Introduction

animation.gif

Pinokio is a browser that lets you locally install, run, and automate any AI on your computer. Everything you can run in your command line can be automated with Pinokio script, with a user-friendly UI.

You can use Pinokio to automate anything, including:

  1. Install AI apps and models
  2. Manage and Run AI apps
  3. Create workflows to orchestrate installed AI apps
  4. Run any command to automate things on your machine
  5. and more...

Features

Here's what makes Pinokio special:

  1. Local: Everything gets installed and runs locally. None of your data is stored on someone else's server.
  2. Free: Pinokio is an open source application that is 100% free to use with no restriction. There is no one to pay for API access, since everything runs on your local machine. Play with AI as much as you want, for free forever.
  3. Private: You don't need to worry about submitting private data just to run AI, everything runs 100% privately on your own machine.
  4. User-friendly Interface: Pinokio provides a user-friendly GUI for running and automating anything that you would normally need to use the terminal for.
  5. Batteries Included: Pinokio is a self-contained system. You do not need to install any other program. Pinokio can automate anything, including program/library installations. The only program you need is Pinokio.
  6. Cross Platform: Pinokio works on ALL operating systems (Windows, Mac, Linux).
  7. Save Storage and Resources: Pinokio has a lot of optimization features that will save you hundreds of gigabytes of disk space. Also, many other resource optimization features (such as memory) all possible with Pinokio.
  8. Expressive Scripting Language: Pinokio script is a powerful automation scripting language with features like memory, dynamic templating, and extensible low level APIs.
  9. Portable: Everything is stored under an isolated folder and everything exists as a file, which means you can easily back up everything or delete apps simply by deleting files.

Architecture

Pinokio takes inspiration from how traditional computers work.

Just like how a computer can do all kinds of things thanks to its comprehensive architecture, Pinokio as a virtual computer is a comprehensive platform for running and automating anything you can imagine with AI.

  1. File System: Where and how Pinokio stores files.
  2. Processor: How pinokio runs tasks.
  3. Memory: How pinokio implements a state machine using its built-in native memory.
  4. Script: The programming language that operates pinokio.
  5. UI: The UI (user interface) through which users access apps.

Quickstart

Pinokio File System

Pinokio is a self-contained platform that lets you install apps in an isolated manner.

  1. Isolated Environment: no need to worry about messing up your global system configurations and environments
  2. Batteries Included: no need to manually install required programs just to install something (such as ffpeg, node.js, visual studio, conda, python, pip, etc.). Pinokio takes care of it automatically.

To achieve this, Pinokio stores everything under a single isolated folder ("pinokio home"), so it never has to rely on your system-wide configs and programs but runs everything in a self-contained manner.

You can set the pinokio home folder when you first set up Pinokio, as well as later change it to a new location from the settings tab.

settings.png

So where are the files stored? Click the "Files" button from the home page:

files.png

This will open Pinokio's home folder in your file explorer:

files_explorer.png

Let's quickly go through what each folder does:

  1. api: stores all the downloaded apps (scripts).
    • The folders inside this folder are displayed on your Pinokio's home.
  2. bin: stores globally installed modules shared by multiple apps so you don't need to install them redundantly.
    • For example, ffmpeg, nodejs, python, etc.
  3. cache: stores all the files automatically cached by apps you run.
    • When something doesn't work, deleting this folder and starting fresh may fix it.
    • It is OK to delete the cache folder as it will be re-populated by the apps you use as you start using apps.
  4. drive: stores all the virtual drives created by the fs.link Pinokio API
  5. logs: stores all the log files for each app.

Hello world

Let's write a script that clones a git repository.

gitjson.png

  1. Create a folder named helloworld under the Pinokio api folder.
  2. Create a file named git.json under the the Pinokio api/helloworld folder.
{
  "run": [{
    "method": "shell.run",
    "params": {
      "message": "git clone https://github.com/pinokiocomputer/test"
    }
  }]
}

Now when you go back to Pinokio, you will see your helloworld repository show up. Navigate into it and click the git.json tab to run it:

gitclone.gif

You will see that an api/helloworld/test folder has been cloned from the https://github.com/pinokiocomputer/test repository.


Templates

We can also dynamically change what commmands to run, and how to run them, using templates.

As an example, let's write a script that runs dir on windows, and ls on linux and mac.

In your api/helloworld folder, create a file named files.json:

{
  "run": [{
    "method": "shell.run",
    "params": {
      "message": "{{platform === 'win32' ? 'dir' : 'ls'}}"
    }
  }]
}
  1. The {{ }} template expression contains a JavaScript expression
  2. There are several variables available inside every template expression, and one of them is platform.
  3. The value of platform is either darwin (mac), win32 (windows), or linux (linux).

This means, on Windows, the above script is equivalent to:

{
  "run": [{
    "method": "shell.run",
    "params": {
      "message": "dir"
    }
  }]
}

Or if it's not windows (mac or linux), it's equivalent to:

{
  "run": [{
    "method": "shell.run",
    "params": {
      "message": "ls"
    }
  }]
}

You can learn more about templates here


Run in daemon mode

When a Pinokio script finishes running, every shell session that was spawned through the script gets disposed of, and all the related processes get shut down.

For example, let's try launching a local web server using http-server. Create a new folder named httpserver under the Pinokio api folder, and create a new script named index.json:

{
  "run": [{
    "method": "shell.run",
    "params": {
      "message": "npx -y http-server"
    }
  }]
}

Then go back to Pinokio and you'll see this app show up on the home page. Click through and click the index.json tab on the sidebar, and it will start this script, which should launch the web server using npx http-server.

But the problem is, right after it launches the server it will immediately shut down and you won't be able to use the web server.

This is because Pinokio automatically shuts down all processes associated with the script when it finishes running all the steps in the run array.

To avoid this, you need to tell Pinokio this app should stay up even after all the steps have run. We simply need to add a daemon attribute:

{
  "daemon": true,
  "run": [{
    "method": "shell.run",
    "params": {
      "message": "npx -y http-server"
    }
  }]
}

Now retry starting the script, and you'll see that the web server starts running and does not shut down.

The web server will serve all the files in the current folder (in this case just index.json), like this:

httpserver.gif

You can stop the script by pressing the "stop" button at the top of the page.

Learn more about daemon mode here


Run multiple commands

You can also run multiple commands with one shell.run call.

Let's try an example. We are going to install, initialize, and launch a documentation engine in one script.

Things like this used to be not accessible for normal people (since you have to run these things in the terminal), but with Pinokio, it's as easy as one click.

  1. Create a folder named docsify under the Pinokio api folder
  2. Create a file named index.json under the api/docsify folder. The index.json file should look like the following:
{
  "daemon": true,
  "run": [{
    "method": "shell.run",
    "params": {
      "message": [
        "npx -y docsify-cli init docs",
        "npx -y docsify-cli serve docs"
      ]
    }
  }]
}

This example does 2 things:

  1. Initialize a docsify Documentation project
  2. Launch the docsify dev server

When you click the dev server link from the Pinokio terminal, it will open the documentation page in a web browser:

docsify.gif

Install packages into venv

One of the common use cases for Pinokio is to:

  1. Create/activate a venv
  2. Install dependencies into the activated venv

Let's try a simple example. This example is a minimal gradio app from the official gradio tutorial

First, create a folder named gradio_demo under Pinokio's api folder.

Next, create a file named app.py in the api/gradio_demo folder.

# app.py
import gradio as gr

def greet(name, intensity):
    return "Hello, " + name + "!" * int(intensity)

demo = gr.Interface(
    fn=greet,
    inputs=["text", "slider"],
    outputs=["text"],
)
demo.launch()

We also need a requirements.txt file that looks like this:

# requirements.txt
gradio

Finally, we need an install.json script that will install the dependencies from the requirements.txt file:

{
  "run": [{
    "method": "shell.run",
    "params": {
      "venv": "env",
      "message": "pip install -r requirements.txt"
    }
  }]
}

The folder structure will look like this:

/PINOKIO_HOME
  /api
    /gradio_demo
      app.py
      requirements.txt
      install.json

Go back to Pinokio and you'll see the gradio_demo app. Click into the UI and click the install.json tab, and it will:

  1. Create a venv folder at path env
  2. Activate the env environment
  3. Run pip install -r requirements.txt, which will install the gradio dependency into the env envrionment.

Here's what the installation process looks like (note that a new env folder has been created at the end):

gradio_install.gif

Learn more about the venv API here


Run an app in venv

continued from the last section.

Now let's write a simple script that will launch the gradio server from the app.py from the last section. Create a file named start.json in the same folder:

{
  "daemon": true,
  "run": [{
    "method": "shell.run",
    "params": {
      "venv": "env",
      "message": "python app.py"
    }
  }]
}

Go back to Pinokio and you'll see that the start.json file now shows up on the sidebar as well. Click to start the start.json script. This will:

  1. activate the env environment we created from the install step
  2. run python app.py in daemon mode (daemon: true), which will launch the gradio server and keep it running.

It will look something like this:

gradio_start.gif

Download a file

Pinokio has a cross-platform API for downloading files easily and reliably (including automatic retries, etc.).

Let's try writing a simple script that downloads a PDF.

First create a folder named download under the Pinokio api folder, and then create a file named index.json:

{
  "run": [{
    "method": "fs.download",
    "params": {
      "uri": "https://arxiv.org/pdf/1706.03762.pdf",
      "dir": "pdf"
    }
  }]
}

This will download the file at https://arxiv.org/pdf/1706.03762.pdf to a folder named pdf (The fs.download API automatically creates a folder at the location if it doesn't already exist). Here's what it looks like:

fsdownload.gif

Learn more about the fs.download API here


Call a script from another script

In many cases you may want to call a script from another script. Some examples:

  1. An orchestration script that spins up stable diffusion and then llama.
  2. An agent that starts stable diffusion, and immediately makes a request to generate an image, and finally stops the stable diffusion server to save resources, automatically.
  3. An agent that makes a request to a llama endpoint, and then feeds the response to a stable diffusion endpoint.

We can achieve this using the script APIs:

Here's an example. Let's create a simple caller.json and callee.json:

caller.json:

{
  "run": [{
    "method": "script.start",
    "params": {
      "uri": "callee.json",
      "params": { "a": 1, "b": 2 }
    }
  }, {
    "method": "log",
    "params": {
      "json2": "{{input}}"
    }
  }]
}

First step, the caller.json will call callee.json with the params { "a": 1, "b": 2 }.

This params object will be passed into the callee.json as args:

callee.json:

{
  "run": [{
    "method": "script.return",
    "params": {
      "ressponse": "{{args.a + args.b}}"
    }
  }]
}

The callee.json script immediately returns the value {{args.a + args.b}} with the script.return call.

Finally, the caller.json will call the last step log, which will print the value {{input}}, which is the return value from callee.json. This will print 3:

localscript.gif


Install, start, and stop remote scripts

The last section explained how you can call a script from within the same repository. But what if you want to call scripts from other repositories?

The script.start API can also download and run remote scripts on the fly.

Create a folder named remotescript under Pinokio api folder and create a file named install.json under the api/remotescript:

{
  "run": [{
    "method": "script.start",
    "params": {
      "uri": "https://github.com/cocktailpeanutlabs/moondream2.git/install.js"
    }
  }, {
    "method": "script.start",
    "params": {
      "uri": "https://github.com/cocktailpeanutlabs/moondream2.git/start.js"
    }
  }, {
    "id": "run",
    "method": "gradio.predict",
    "params": {
      "uri": "{{kernel.script.local('https://github.com/cocktailpeanutlabs/moondream2.git/start.js').url}}",
      "path": "/answer_question_1",
      "params": [
        { "path": "https://media.timeout.com/images/105795964/750/422/image.jpg" },
        "Explain what is going on here"
      ]
    }
  }, {
    "method": "log",
    "params": {
      "json2": "{{input}}"
    }
  }, {
    "method": "script.stop",
    "params": {
      "uri": "https://github.com/cocktailpeanutlabs/moondream2.git/start.js"
    }
  }]
}
  1. The first step starts the script https://github.com/cocktailpeanutlabs/moondream2.git/install.js.
    • If the moondream2.git repository already exists on Pinokio, it will run the install.js script.
    • If it doesn't already exist, Pinokio automatically clones the https://github.com/cocktailpeanutlabs/moondream2.git repository first, and then starts the install.js script after that.
  2. After the install has finished, it then launches the gradio app using the https://github.com/cocktailpeanutlabs/moondream2.git/start.js script. This script will return after the server has started.
  3. Now we run gradio.predict, using the kernel.script.local() API to get the local variable object for the start.js script, and then getting its url value (which is programmatically set inside the moondream2.git/start.js script).
    • Basically, this step makes a request to the gradio endpoint to ask the LLM "Explain what is going on here", passing an image.
  4. Next, the return value from the gradio.predict is logged to the terminal using the log API.
  5. Finally, we stop the moondream2/start.js script to shut down the moondream gradio server using the script.stop API.
    • If we don't call the script.stop, the moondream2 app will keep running even after this script halts.

Here's what it would look like:

remotescript.gif

The ability to run script.start, and then script.stop is very useful for running AI on personal computers, because most personal computers do not have unbounded memory, and your computer will quickly run out of memory if you cannot shut down these AI engines programmatically.

With script.stop you can start a script, get its response, and immediatley shut it down once the task has finished, which will free up the system memory, which you can use for running other subsequent AI tasks.


Build UI with pinokio.js

Pinokio apps have a simple structure:

  1. shortcut: The app shortcut that shows up on Pinokio home.
  2. app: The main UI layout for the app

Shortcut

shortcut.png

App

main.gif

By default if you do not have a pinokio.js file in your project,

While this is convenient for getting started, it's not flexible enough:

  1. You can't control what gets displayed in the menu bar
  2. You can't control how the scripts are launched (by passing params for example)
  3. You can't control how the app is displayed
    • The title of the app will be your folder name
    • There is no description
    • The icon will just show a default icon.

To customize how your app itself behaves, you will want to write a UI script named pinokio.js.

Let's try writing a minimal UI:

  1. Create a folder named downloader in the /PINOKIO_HOME/api folder
  2. Add any icon to the /PINOKIO_HOME/api/downloader folder and name it icon.png
  3. Create a file named /PINOKIO_HOME/api/downloader/download.json
  4. Create a file named /PINOKIO_HOME/api/downloader/pinokio.js

/PINOKIO_HOME/api/downloader/icon.png

doraemon.png

/PINOKIO_HOME/api/downloader/download.json

{
  "run": [{
    "method": "shell.run",
    "params": {
      "message": "git clone {{input.url}}"
    }
  }]
}

/PINOKIO_HOME/api/downloader/pinokio.js

module.exports = {
  title: "Download Anything",
  description: "Download a git repository",
  icon: "icon.png",
  menu: [{
    text: "Start",
    href: "download.json",
    params: {
      url: "https://github.com/cocktailpeanut/dalai"
    }
  }]
}

The end result will look like this in your file explorer:

downloader.png

Now go back to Pinokio and refresh, and you will see your app show up:

custom_ui_preview.png

Now when you click into the app, you will see the following:

custom_ui.gif

  1. You will see the menu item Start.
  2. Click this to run the download.json which is specified by the href attribute.
  3. Also note that the script is passing the value of https://github.com/cocktailpeanut/dalai as the params.url value.
  4. The params passed to the download.json is made available as the input variable, so the git clone {{input.url}} will be instantiated as git clone https://github.com/cocktailpeanut/dalai.

Publish your script

Once you have a working script repository, you can publish to any git hosting service and share the URL, and anyone will be able to install and run your script.


Install script from any git url

You can install any pinokio script repository very easily:

  1. Click the "Download from URL" button at the top of the Discover page.
  2. Enter the git URL (You can optionally specify the branch as well).

download_git.gif


List your script on the directory

If you published to github, you can tag your repository with "pinokio" to make it show up in the "latest" section of the Discover page.

tagging.gif

Now it will automatically show up on the "latest" section (at the bottom of the "Discover" page):

latest.png

Pinokio constructs the "Latest" section automatically from GitHub "/repositories" API at https://api.github.com/search/repositories?q=topic:pinokio&sort=updated&direction=desc

So if you tagged your repository as "pinokio" but doesn't show up, check in the API result, and try to figure out why it's not included in there.


Auto-generate app launchers

While it is important to understand how all this works, in most cases you may want a simple "launcher combo", which includes:

  1. App install script: Installs the app dependencies
  2. App Launch script: Starts the app
  3. UI: Displays the launcher UI.
  4. Reset script: Resets the app state when something goes wrong.
  5. Update script: Updates the app to the latest version with 1 click.

This use case is needed so often, that we've implemented a program that automatically generates these scripts instantly. It's called Gepeto.


Adding posts to the Newsfeed

Often you may want to share more info about each script. You can use the newsfeed for that.

pinokio_meta.gif

To do this, simply create a pinokio_meta.json file, with a posts array attribute, where each item is an x.com URL. Here's an example:

{
  "posts": [
    "https://x.com/cocktailpeanut/status/1819482952071323788",
    "https://x.com/cocktailpeanut/status/1819439443394109837",
    "https://x.com/cocktailpeanut/status/1800944955738685648",
    "https://x.com/cocktailpeanut/status/1754244867159413001",
    "https://x.com/cocktailpeanut/status/1729884460114727197",
    "https://x.com/cocktailpeanut/status/1728075614807048208"
  ]
}

You can see it in action: https://github.com/cocktailpeanutlabs/comfyui/blob/main/pinokio_meta.json

Once you publish, this will be immediately reflected on the script landing page.


Gepeto


Gepeto is a program that lets you automatically generate Pinokio scripts, specifically for app launchers.

Let's start by actually generating an app and its launcher in 1 minute.

Gepeto Quickstart


1. Install Gepeto on Pinokio

If you don't have gepeto installed already, find it on Pinokio and install first.

gepeto_install.gif

2. Generate Scripts with Gepeto

You will see a simple web UI that lets you fill out a form. For simplicity, just enter Helloworld as the project name, and press submit.

gepeto_generate.gif

This will initialize a project. When you go back to Pinokio home,

  1. You will see a new entry named Helloworld. Click into it and you'll see the launcher screen.
  2. Also, check your /PINOKIO_HOME/api folder, you will find a new folder named Helloworld with some script files.

3. Install and Start the App

Now let's click the install button to install the app, and when it's over, click start to launch.

gepeto_launch.gif

You will see a minimal gradio app, where you can enter a prompt and it will generate an image using Stable Diffusion XL Turbo.

So what just happened? We've just created an empty project, which comes with a minimal demo app.

Let's take a look at each generated file in the next section.


Creating an empty project

Gepeto automatically generates a minimal set of scripts required for an app launcher. A typical app launcher has the following features:

  1. Install: Install the dependencies required to run the app. (install.js)
  2. Launch: Launch the app itself. (start.js)
  3. Reset install: Reset all the installed dependencies in case you need to reinstall fresh. (reset.js)
  4. Update: Update to the latest version when the project gets updated. (update.js)
  5. GUI: The script that describes what the launcher will look like and behave on Pinokio home and as a sidebar menu. (pinokio.js)

Here's what it looks like:

type2.png

Note that in addition to the scripts mentioned above, gepeto has generated some extra files:

The notable files to look at are app.py and requirements.txt files:

app.py
import gradio as gr
import torch
from diffusers import DiffusionPipeline
import devicetorch
# Get the current device ("mps", "cuda", or "cpu")
device = devicetorch.get(torch)
# Create a diffusion pipeline
pipe = DiffusionPipeline.from_pretrained("stabilityai/sdxl-turbo").to(device)
# Run inference
def generate_image(prompt):
    return pipe(
      prompt,
      num_inference_steps=2,
      strength=0.5,
      guidance_scale=0.0
    ).images[0]
# Create a text input + image output UI with Gradio
app = gr.Interface(fn=generate_image, inputs="text", outputs="image")
app.launch()
requirements.txt

The below are the libraries required to run app.py.

transformers
accelerate
diffusers
gradio
devicetorch

So how are these files actually used?

install.js

If you look inside install.js, you will see that it's running pip install -r requirements.txt to install the dependencies inside the file, like this:

module.exports = {
  run: [
    // Delete this step if your project does not use torch
    {
      method: "script.start",
      params: {
        uri: "torch.js",
        params: {
          venv: "env",                // Edit this to customize the venv folder path
          // xformers: true   // uncomment this line if your project requires xformers
        }
      }
    },
    // Edit this step with your custom install commands
    {
      method: "shell.run",
      params: {
        venv: "env",                // Edit this to customize the venv folder path
        message: [
          "pip install -r requirements.txt"
        ],
      }
    },
    //  Uncomment this step to add automatic venv deduplication (Experimental)
    //  {
    //    method: "fs.link",
    //    params: {
    //      venv: "env"
    //    }
    //  },
    {
      method: "notify",
      params: {
        html: "Click the 'start' tab to get started!"
      }
    }
  ]
}
  1. The first step runs script.start to call a script named torch.js. This installs torch.
  2. The second step runs pip install -r requirements.txt file to install everything in that file.
start.js

And if you look inside start.js, you will see that it's running python app.py to start the app:

module.exports = {
  daemon: true,
  run: [
    // Edit this step to customize your app's launch command
    {
      method: "shell.run",
      params: {
        venv: "env",                // Edit this to customize the venv folder path
        env: { },                   // Edit this to customize environment variables (see documentation)
        message: [
          "python app.py",    // Edit with your custom commands
        ],
        on: [{
          // The regular expression pattern to monitor.
          // When this pattern occurs in the shell terminal, the shell will return,
          // and the script will go onto the next step.
          "event": "/http:\/\/\\S+/",

          // "done": true will move to the next step while keeping the shell alive.
          // "kill": true will move to the next step after killing the shell.
          "done": true
        }]
      }
    },
    // This step sets the local variable 'url'.
    // This local variable will be used in pinokio.js to display the "Open WebUI" tab when the value is set.
    {
      method: "local.set",
      params: {
        // the input.event is the regular expression match object from the previous step
        url: "{{input.event[0]}}"
      }
    },
//    Uncomment this step to enable local wifi sharing (access the app from devices on the same network)
//    {
//      method: "proxy.start",
//      params: {
//        uri: "{{local.url}}",
//        name: "Local Sharing"
//      }
//    }
  ]
}
  1. The first step starts a shell (shell.run), activates a venv environment at env path, and runs the command python app.py. It then monitors the shell terminal for any regular expression matching the pattern /http:\/\/[0-9.:]+/, and goes to the next step (without terminating the shell).
  2. The next step sets the local variable url as using the regular expression match from the previous step.

And that's all there is to it!


Customizing the empty project

Just to make sure we get the point across, let's try modifying the auto-generated code to customize the app:

Open the app.py and just replace it with something even simpler:

import gradio as gr
def square(num):
    return num * num
app = gr.Interface(fn=square, inputs="number", outputs="number")
app.launch()

Also you can get rid of everything but gradio in the requirements.txt file:

gradio

Now restart the app. It's an app that takes a number and displays its square value:

Creating a launcher for an existing project

So far we've seen "how to start from scratch". But what if you want to take an EXISTING project and simply write a launcher for it? For example:

  1. Write a local launcher for ComfyUI
  2. Write a local launcher for FaceFusion
  3. Write a local launcher for HuggingFace Spaces
  4. so on.

In this case, you just need to enter the git repository URL of the project you're trying to install, when you first run gepeto.

gepeto_web.png

As an example, let's build a launcher for Devika, an AI agent application.

  1. Enter devika-launcher in the Project Name field.
  2. Enter https://raw.githubusercontent.com/stitionai/devika/main/.assets/devika-avatar.png in the Icon URL field.
  3. Enter https://github.com/stitionai/devika in the Git URL field.

and press Submit. Gepeto will generate the launcher. Go to Pinokio home, you'll find the generated launcher:

devika-home.png

Click into it and click the Files tab to view the generated folder:

devika-view.gif

The generated folder looks like this:

devika-launcher.png

Note that there are no app.py and requirements.txt files. Since we entered a git URL, Gepeto assumes that the actual app logic will be in that repository and therefore doesn't generate these two files in this case.

install.js

Let's take a look at install.js. This is the default script gepeto has generated:

module.exports = {
  run: [
    // Edit this step to customize the git repository to use
    {
      method: "shell.run",
      params: {
        message: [
          "git clone https://github.com/stitionai/devika app",
        ]
      }
    },
    // Delete this step if your project does not use torch
    {
      method: "script.start",
      params: {
        uri: "torch.js",
        params: {
          venv: "env",                // Edit this to customize the venv folder path
          path: "app",                // Edit this to customize the path to start the shell from
          // xformers: true   // uncomment this line if your project requires xformers
        }
      }
    },
    // Edit this step with your custom install commands
    {
      method: "shell.run",
      params: {
        venv: "env",                // Edit this to customize the venv folder path
        path: "app",                // Edit this to customize the path to start the shell from
        message: [
          "pip install gradio devicetorch",
          "pip install -r requirements.txt"
        ]
      }
    },
    //  Uncomment this step to add automatic venv deduplication (Experimental)
    //  {
    //    method: "fs.link",
    //    params: {
    //      venv: "env"
    //    }
    //  },
    {
      method: "notify",
      params: {
        html: "Click the 'start' tab to get started!"
      }
    }
  ]
}

This is the default install script generated by Gepeto.

  1. Run git clone https://github.com/stitionai/devika app to download the git repository to app folder.
  2. Call torch.js script, which automatically installs the correct version of Pytorch for the current system.
  3. Run pip install gradio devicetorch and then pip install -r requirements.txt, to install dependencies.

This script assumes that the installation for this Devika project is done by running pip install -r requirements.txt. Normally this works in many cases, but often you have to do some more. Let's take a look at Devika README.md:

devika-install.png

Looks like we need to do some more:

  1. In addition to pip install -r requirements.txt we also need to install Playwright.
  2. Also we need to install the NPM dependencies with bun install.

Let's edit the install.js to reflect this:

module.exports = {
  run: [
    // Edit this step to customize the git repository to use
    {
      method: "shell.run",
      params: {
        message: [
          "git clone https://github.com/stitionai/devika app",
        ]
      }
    },
    // Delete this step if your project does not use torch
    {
      method: "script.start",
      params: {
        uri: "torch.js",
        params: {
          venv: "env",                // Edit this to customize the venv folder path
          path: "app",                // Edit this to customize the path to start the shell from
          // xformers: true   // uncomment this line if your project requires xformers
        }
      }
    },
    // Edit this step with your custom install commands
    {
      method: "shell.run",
      params: {
        venv: "env",                // Edit this to customize the venv folder path
        path: "app",                // Edit this to customize the path to start the shell from
        message: [
          "pip install gradio devicetorch",
          "pip install -r requirements.txt",
          "playwright install --with-deps"
        ]
      }
    },
    {
      method: "shell.run",
      params: {
        path: "app/ui",
        message: "npm install"
      }
    },
    //  Uncomment this step to add automatic venv deduplication (Experimental)
    //  {
    //    method: "fs.link",
    //    params: {
    //      venv: "env"
    //    }
    //  },
    {
      method: "notify",
      params: {
        html: "Click the 'start' tab to get started!"
      }
    }
  ]
}
  1. Just notice the third step: we've added the additional command playwright install --with-deps
  2. Additionally, the fourth step has been added, where we run npm install (We use npm install instead of the proposed bun install since it's effectively the same and NPM is included in Pinokio by default)
start.js

Now, what about actually launching the app? The start.js script takes care of this. Let's take a look at the generated file:

module.exports = {
  daemon: true,
  run: [
    {
      method: "shell.run",
      params: {
        venv: "env",                // Edit this to customize the venv folder path
        env: { },                   // Edit this to customize environment variables (see documentation)
        path: "app",                // Edit this to customize the path to start the shell from
        message: [
          "python app.py",    // Edit with your custom commands
        ],
        on: [{
          // The regular expression pattern to monitor.
          // When this pattern occurs in the shell terminal, the shell will return,
          // and the script will go onto the next step.
          "event": "/http:\/\/\\S+/",

          // "done": true will move to the next step while keeping the shell alive.
          // "kill": true will move to the next step after killing the shell.
          "done": true
        }]
      }
    },
    {
      // This step sets the local variable 'url'.
      // This local variable will be used in pinokio.js to display the "Open WebUI" tab when the value is set.
      method: "local.set",
      params: {
        // the input.event is the regular expression match object from the previous step
        url: "{{input.event[0]}}"
      }
    },
  ]
}

The generated script runs the default command python app.py. But again, we need to make some changes to the commands. Let's take a look at the README.md file https://github.com/stitionai/devika?tab=readme-ov-file#installation:

devikia-launch.png

  1. We need to run python devika.py for the backend
  2. We need to then run bun run start for the frontend (or npm run start)

Here's what the updated start.js script looks like:

module.exports = {
  daemon: true,
  run: [
    {
      method: "shell.run",
      params: {
        venv: "env",                // Edit this to customize the venv folder path
        env: { },                   // Edit this to customize environment variables (see documentation)
        path: "app",                // Edit this to customize the path to start the shell from
        message: [
          "python devika.py",
        ],
        on: [{
          "event": "/Devika is up and running/i",   // wait until the terminal prints this message
          "done": true
        }]
      }
    },
    {
      method: "shell.run",
      params: {
        path: "app/ui",
        message: "npm run start",
        on: [{ "event": "/http:\/\/\\S+/", "done": true }]
      }
    },
    {
      // This step sets the local variable 'url'.
      // This local variable will be used in pinokio.js to display the "Open WebUI" tab when the value is set.
      method: "local.set",
      params: {
        // the input.event is the regular expression match object from the previous step
        url: "{{input.event[0]}}"
      }
    },
  ]
}

Here are the changes:

  1. instead of python app.py, now we have the python devika.py command.
  2. The python devika.py command waits until the terminal encounters the regulare expression pattern /Devika is up and running/i. This ensures that it doesn't move onto the next step until the server has fully started.
  3. Also, we have a new step that runs npm run start
  4. The npm run start waits until the terminal encounters the pattern /http:\/\/\\S+/. This takes advantage of the fact that the app prints the endpoint URL at the end of the launch.

After we've updated both the install.js and start.js files, let's go back to Pinokio and try installing and starting:

devika_launch.gif


Adding cross platform support

Often we encounter projects that DO NOT support cross platform out of the box. (For example only support CUDA--Nvidia GPUs--and not Macs).

Normally you can find out very quickly whether an app supports cross platform, simply by searching for cuda in the app code.

If there's any part of the code that hardcodes "cuda" as a device, that means it only works for CUDA.

We can fix this by simply finding all these occurrences and replace the hardcoded "cuda" with the correct device value for the user's platform.

Let's walk through the process step by step:

  1. Create a copy of the original project (so you can edit the code).
  2. Update the app code to support cross platform
  3. Use this copy repository (instead of the original project) when running gepeto.

1. Create a copy

Most open source AI projects are hosted on GitHub or HuggingFace.

Before you make changes to the code, you need to create your own copy fork the original project to create your own version.

HuggingFace Spaces

On HuggingFace Spaces, you need to duplicate the space. Make sure to set it to public.

hf_duplicate.gif

GitHub

On GitHub, you need to fork a repository.

gh_fork.gif

2. Clone the repository to your machine

Now that you have your own copy, you can clone the git repository to your local machine to start editing the code.

Let's say your repository is https://huggingface.co/spaces/cocktailpeanut/cosxl

You can clone it from terminal using:

git lfs install
git clone https://huggingface.co/spaces/cocktailpeanut/cosxl

The git lfs install is for allowing large files, which happens often when the repository contains large files.

Now you are ready to edit the files to add cross platform support.

3. Add device support for Torch

Many projects only support CUDA devices (Nvidia GPU). To make sure apps support non-CUDA devices, we need to:

  1. Find all occurrences of "cuda" in the app code (for example app.py)
  2. Replace all those occurrences with a variable named device
  3. Make sure the device variable is correctly set

Let's take a look at an example:

# app.py
import torch
...
pipe_edit = CosStableDiffusionXLInstructPix2PixPipeline.from_single_file(edit_file, num_in_channels=8)
pipe_edit.scheduler = EDMEulerScheduler(sigma_min=0.002, sigma_max=120.0, sigma_data=1.0, prediction_type="v_prediction")
pipe_edit.to("cuda")

pipe_normal = StableDiffusionXLPipeline.from_single_file(normal_file, torch_dtype=torch.float16)
pipe_normal.scheduler = EDMEulerScheduler(sigma_min=0.002, sigma_max=120.0, sigma_data=1.0, prediction_type="v_prediction")
pipe_normal.to("cuda")

This python code has "cuda" hardcoded in two places:

In this case we need to replace these "cuda" strings with the user's actual device.

We can do this by using a minimal library called devicetorch.

First add a line in requirements.txt to include devicetorch:

# requirements.txt
devicetorch

Next, import devicetorch and call devicetorch.get(torch) to get the actual device name:

# app.py
import torch
import devicetorch
...

# Dynamically get the current device name: will return either "cuda", "mps", or "cpu".
device = devicetorch.get(torch)

pipe_edit = CosStableDiffusionXLInstructPix2PixPipeline.from_single_file(edit_file, num_in_channels=8)
pipe_edit.scheduler = EDMEulerScheduler(sigma_min=0.002, sigma_max=120.0, sigma_data=1.0, prediction_type="v_prediction")
pipe_edit.to(device)

pipe_normal = StableDiffusionXLPipeline.from_single_file(normal_file, torch_dtype=torch.float16)
pipe_normal.scheduler = EDMEulerScheduler(sigma_min=0.002, sigma_max=120.0, sigma_data=1.0, prediction_type="v_prediction")
pipe_normal.to(device)

There are some cases where it's much more complicated and this method doesn't work (In these cases I recommend asking the original project author to officially support MPS).

But in most cases, above approach is enough to add cross platform support for any AI app.

4. More torch handling

Often when you do the "cuda" check (as mentioned above), you will ALSO account cuda specific code snippets like this:

torch.cuda.empty_cache()

Again, this code assumes that it will only run on CUDA devices, and it will FAIL if you run the code on an MPS (Mac) device.

The devicetorch library also has a utility method named devicetorch.empty_cache(torch) to take care of this. Just comment out the existing code and replace it with devicetorch.empty_cache(torch)

#torch.cuda.empty_cache()
devicetorch.empty_cache(torch)

This will automatically run:

4. Run gepeto

Now push the updates back to your copy repository. We will be using THIS repository to install the app (not the original repository).

When you run gepeto, you'll see the Git URL field:

gepeto_web.png

Enter YOUR repository url, and press "Submit". That's all! Try installing with the generated script!


Downloading files with script

Sometimes, the project will tell you you need to download certain files and place them inside certain folder paths.

For example, it may say:

Download https://huggingface.co/stabilityai/stable-diffusion-xl-base-1.0/resolve/main/sd_xl_base_1.0.safetensors to models/checkpoints

Download https://huggingface.co/stabilityai/stable-diffusion-xl-refiner-1.0/resolve/main/sd_xl_refiner_1.0.safetensors to models/checkpoints

We can actually use the built-in fs.download API to download these files:

{
  "run": [{
    ...
  }, {
    "method": "fs.download",
    "params": {
      "url": "https://huggingface.co/stabilityai/stable-diffusion-xl-base-1.0/resolve/main/sd_xl_base_1.0.safetensors",
      "dir": "app/models/checkpoints"
    }
  }, {
    "method": "fs.download",
    "params": {
      "url": "https://huggingface.co/stabilityai/stable-diffusion-xl-refiner-1.0/resolve/main/sd_xl_refiner_1.0.safetensors",
      "dir": "app/models/checkpoints"
    }
  }]
}

This will download the files into those directories.

If the folder doesn't exist, it will create the folders first automatically.


Porting huggingface spaces to local

  1. Create a copy
  2. Use the app.py and requirements.txt files
  3. Remove the spaces

Sometimes an app may have some additional changes.

  1. Huggingface spaces: When trying to make a localized version of a Huggingface space that utilizes Zero GPU, you will need to comment out the @spaces.GPU declarations.
  2. Environment variables: When the code makes use of environment variables (Search for os.environ.get(...), this means the app is expecting an environment variable.

1. Handling Huggingface Space

Some huggingface spaces make use of a feature called Zero GPU, which dynamically assigns GPU to each app based on demand.

These are Huggingface-specific feature, and is not required when running locally. Here's an example usage:

import spaces
from diffusers import DiffusionPipeline

pipe = DiffusionPipeline.from_pretrained(...)
pipe.to('cuda')

@spaces.GPU
def generate(prompt):
    return pipe(prompt).images

gr.Interface(fn=generate, inputs=gr.Text(), outputs=gr.Gallery()).launch()

Because we don't use the spaces feature, we can comment out these spaces related lines:

The result:

#import spaces
from diffusers import DiffusionPipeline

pipe = DiffusionPipeline.from_pretrained(...)
pipe.to('cuda')

#@spaces.GPU
def generate(prompt):
    return pipe(prompt).images

gr.Interface(fn=generate, inputs=gr.Text(), outputs=gr.Gallery()).launch()

2. Environment Variables

Sometimes the code may be looking for system environment variables. To find out if this is the case, search for: os.environment.get.

For example, let's say the code has:

# app.py
mps_fallback = os.environ.get("PYTORCH_ENABLE_MPS_FALLBACK")

You can pass in the PYTORCH_ENABLE_MPS_FALLBACK environment variable by setting the env object when launching app.py, like this:

{
  "run": [{
    "method": "shell.run",
    "params": {
      "message": "python app.py",
      "env": {
        "PYTORCH_ENABLE_MPS_FALLBACK": "1"
      }
    }
  }]
}

Guides

This section will explain some frequently used techniques for writing scripts.

Install Torch

A lot of AI projects rely on PyTorch. However, installing PyTorch is a bit tricky. Let's take a look at an example.

Problem

Let's imagine a project with the following folder structure (a typical huggingface gradio space is structured this way):

app.py
requirements.txt
install.js

The requirements.txt may look something like this:

diffusers
accelerate
torch
transformers
gradio

A naive way to write an install script install.js would be something like this:

module.exports = {
  "run": [{
    "method": "shell.run",
    "params": {
      "venv": "env",
      "message": "pip install -r requirements.txt"
    }
  }]
}

However this won't work for many cases, because with PyTorch, every OS/GPU combination has its own unique install command, as can be seen on the Official PyTorch Website (See the bottom line "Run this Command:"):

torch.gif

Solution

To solve this problem and port AI projects to run locally and cross-platform, we need to:

  1. Update ignore the generic torch, torchvision, and torchaudio declarations inside requirements.txt.
  2. Update the install.json so it installs correct versions of Torch.

1. Update requirements.txt

First, let's comment out any occurrence of torch, torchvision, and torchaudio, since we will write a custom installer for these:

diffusers
accelerate
#torch        <= commented out, will be ignored.
transformers
gradio

Here's an actual example: https://huggingface.co/spaces/cocktailpeanut/SPRIGHT-T2I/blob/main/requirements.txt

2. Update the install script

Let's update the install.js to add all possible combintations of torch install commands:

module.exports = {
  "run": [
    // Torch for windows nvidia
    {
      "when": "{{platform === 'win32' && gpu === 'nvidia'}}",
      "method": "shell.run",
      "params": {
        "venv": "env",
        "message": "pip install torch torchvision torchaudio  --index-url https://download.pytorch.org/whl/cu121"
      }
    },
    // Torch for windows amd
    {
      "when": "{{platform === 'win32' && gpu === 'amd'}}",
      "method": "shell.run",
      "params": {
        "venv": "env",
        "message": "pip install torch-directml"
      }
    },
    // Torch for windows cpu
    {
      "when": "{{platform === 'win32' && (gpu !== 'nvidia' && gpu !== 'amd')}}",
      "method": "shell.run",
      "params": {
        "venv": "env",
        "message": "pip install torch torchvision torchaudio"
      }
    },
    // Torch for mac
    {
      "when": "{{platform === 'darwin'}}",
      "method": "shell.run",
      "params": {
        "venv": "env",
        "message": "pip install --pre torch torchvision torchaudio --index-url https://download.pytorch.org/whl/nightly/cpu"
      }
    },
    // Torch for linux nvidia
    {
      "when": "{{platform === 'linux' && gpu === 'nvidia'}}",
      "method": "shell.run",
      "params": {
        "venv": "env",
        "message": "pip install torch torchvision torchaudio"
      }
    },
    // Torch for linux rocm (amd)
    {
      "when": "{{platform === 'linux' && gpu === 'amd'}}",
      "method": "shell.run",
      "params": {
        "venv": "env",
        "message": "pip install torch torchvision torchaudio --index-url https://download.pytorch.org/whl/rocm5.7"
      }
    },
    // Torch for linux cpu
    {
      "when": "{{platform === 'linux' && (gpu !== 'amd' && gpu !=='amd')}}",
      "method": "shell.run",
      "params": {
        "venv": "env",
        "message": "pip install torch torchvision torchaudio --index-url https://download.pytorch.org/whl/cpu"
      }
    },
    // Install requirements.txt
    {
      "method": "shell.run",
      "params": {
        "venv": "env",
        "message": "pip install -r requirements.txt"
      }
    }
  ]
}
  1. This will walk through the run array and check the when clauses, and only execute the commands when the conditions are met.
  2. Then in the last step, it will run the original pip install -r requirements.txt

Install Torch and Xformers

Xformers is another library that is frequently used in AI projects, but only for CUDA (NVIDIA GPUs).

Whenever you come across a project that includes xformers as a dependency, you will need to do the same thing you did for torch:

  1. comment out the xformers line from the requirements.txt
  2. add a custom handling logic for xformers into the install script, so it only gets installed when the app is running on nvidia GPU.

For example, an udpated requirements.txt file may look like this:

diffusers
accelerate
#torch        <= commented out, will be ignored.
#xformers     <= commented out, will be ignored.
transformers
gradio

Additionally, we update the install script so it correctly handles xformers when the GPU is nvidia:

  1. check if the gpu is nvidia.
  2. and if so, add the xformers to the pip install command.
module.exports = {
  "run": [
    // Torch for windows nvidia
    {
      "when": "{{platform === 'win32' && gpu === 'nvidia'}}",
      "method": "shell.run",
      "params": {
        "venv": "env",
        "message": "pip install torch torchvision torchaudio xformers --index-url https://download.pytorch.org/whl/cu121"
      }
    },
    // Torch for windows amd
    {
      "when": "{{platform === 'win32' && gpu === 'amd'}}",
      "method": "shell.run",
      "params": {
        "venv": "env",

      }
    },

    {
      "when": "{{platform === 'win32' && (gpu !== 'nvidia' && gpu !== 'amd')}}",
      "method": "shell.run",
      "params": {
        "venv": "env",
        "message": "pip install torch torchvision torchaudio"
      }
    },

      "when": "{{platform === 'darwin'}}",
      "method": "shell.run",

}

The only lines that have been changed are:

Build an App Launcher Instantly

Pinokio script can be used to do all kinds of things (run shell commands, make network requests, write to files, etc.), but sometimes we want a dead simple way to auto-generate some scripts to install and run some apps.

For this specific--but very frequent--use case, we have a program called gepeto, which automatically generates a set of scripts commonly used for installing, running, and managing apps.

If building an app launcher is your goal, we recommend you start from using Gepeto.


File System

Home directory

Pinokio stores everything inside a centralized location (Pinokio Home Directory). This means you can:

  1. Remove apps simply by deleting folders (No messy sysetm-wide installed files and DLLs)
  2. Back up either the entire workspace or individual apps simiply by backing up folders.

home.png

When you first install Pinokio, you will be asked to set the home folder path.

You can also update it later in the settings tab.


Self-contained File System

The top level folders under the Pinokio home directory look like the following

We'll use the /PINOKIO_HOME notation to refer to the pinokio home directory from this point.

The /PINOKIO_HOME folder is whichever folder you set as your Pinokio home.

/PINOKIO_HOME
  /api
    /stable-diffusion-webui.git
    /comfyui.git
    /brushnet.git
    ...
  /bin
    /miniconda
    /homebrew
    /py
  /drive
    /drives
      /peers
        ...
      /pip
  /cache
  /logs

/api

The api folder is where the downloaded app repositories are stored. An API folder can contain either of the following:

  1. downloaded from git: repositories you downloaded from git.
  2. locally created: you can manually create folders and work from there.

/bin

The bin folder stores all the binaries commonly used by AI engines.

Things installed into the /bin folder can be shared across multiple apps in the /api folder.

/drive

The drive folder stores virtual drives, used for deduplicating redundant files to save the disk space, sharing data across multiple apps, and overall separating data from application for many useful scenarios.

Learn more about virtual drives here

/cache

The cache folder stores cache files programmatically downloaded or generated by apps (through pip, torch, huggingface-cli, etc.)

/logs

The logs folder contains the logs, essential for debugging when something doesn't work.


Distributed File URI

Pinokio uses a unique distributed URI system that lets you:

Let's first take a look at the most obvious option--Relative file paths.

Relative Path

A URI can be a relative path. The path is resolved relative to the currently running script.

Let's say we have a folder at /PINOKIO_HOME/api/myapp, which looks like this:

/myapp
  start.js
  subroutine.json

And here's what start.js looks like:

// start.js
module.exports = {
  "run": [{
    "method": "script.start",
    "params": {
      "uri": "subroutine.json"
    }
  }]
}

In this example, the start.js script calls another script named subroutine.json. This is a relative path.

The Pinokio interpreter automatically resolves the path of subroutine.json as the same folder that contains start.js, which is /PINOKIO_HOME/api/myapp.

So the script.start call will look for the file /PINOKIO_HOME/api/myapp/subroutine.json and run that script.

Git Path

The relative path is enough for most cases, but what if the script you want to run is NOT from the same repository? What if you want to download a remote repository and run some script inside it?

This is where the Git URI scheme comes in.

Specification

This goal is achieved by adopting the git url protocol.

<REMOTE_GIT_URI>/<RELATIVE_PATH_WITHIN_THE_REPOSITORY>

For example, to reference a file at install.js inside the https://github.com/cocktailpeanutlabs/comfyui.git git repository, the HTTP path would look like:

https://github.com/cocktailpeanutlabs/comfyui.git/install.js

Some rules:

  1. The <REMOTE_GIT_URI> must end with .git (This is the standard way to reference git repositories)
  2. The URL info is derived from the .git/config file within the downloaded repository.
    • This means a local repository without .git/config won't have a publicly addresable URI. You will need to publish it somewhere before you can use the universal git uri.

Content Addressable

In addition to being able to reference filenames, you can also reference files within a specific version, such as:

  1. a file path in a specific commit hash
  2. a file path in a specific branch
// commit hash uri
{
  "method": "script.start",
  "params": {
    "uri": "https://github.com/facefusion/facefusion-pinokio.git/install.js",
    "hash": "ced4e76aa2a7c60a08535af8c340efea153ec381"
  }
}

// git branch uri
{
  "method": "script.start",
  "params": {
    "uri": "https://github.com/facefusion/facefusion-pinokio.git/install.js",
    "branch": "master"
  }
}

Above scripts will:

  1. check whether the repository is locally installed
  2. if not, git clone the repository https://github.com/facefusion/facefusion-pinokio.git
  3. switch to the commit hash (ced4e76aa2a7c60a08535af8c340efea153ec381) or the branch (master)
  4. resolve the locally downloaded file path install.js from the auto-downloaded git repository
  5. and run it

Virtual Drive

Introduction

Virtual drives let you store data outside of applications while making them behave as if they are inside, by utilizing symbolic links.

virtualdrive.png

This is useful for various cases such as:

  1. Storing files that persist across multiple installs (Similar to Docker Volumes)
  2. Sharing files across multiple apps (for example, ComfyUI, Fooocus, and Stable-Diffusion-WebUI sharing .safetensor AI model files among them so you don't have to download redundant files for each app)
  3. Storing all the library files (such as pytorch) in a deduplicated manner, which saves a lot of disk space.

Use Cases

  1. Persistence: Because Drives exist independently, they stay around even if you delete the apps or update them. If you want to store large AI model files for some apps, and want the models to persist even when you delete or update the app, this is very useful.
  2. Shareable: Virtual drives can also specify peers, which lets multiple apps share a single virtual drive. When you specify a peer array, the fs.link API will look for any pre-existing peer drive before creating a new dedicated drive. If a peer drive exists, the fs.link will simply link to the discovered drive path instead of creating a new one.
  3. Save Disk Space: The primary purpose of the virtual drive is to avoid duplicate files as much as possible, which significantly saves disk space. In many cases, it can save tens of gigabytes per application.

How it works

1. Symbolic Link

Virtual drives are internally implemented with symbolic links on Linux/Mac, and junctions on Windows.

When you create a set of virtual drives using the fs.link API, here's what happens:

  1. Create a set of virtual drive folders under the /PINOKIO_HOME/drive folder.
  2. Create symbolic links from the specified app folders to the newly created virtual drive folders (which exist OUTSIDE of the app repository)
  3. Thanks to the symbolic links, when you reference one of the app folders that link to the virtual drives, it will behave as if the files are actually insdie the specified app folder path, but in reality the files are stored in the external "virtual drive" folder.
  4. When you delete the app repository, the files you stored using virtual drivees will stay, since the virtual drives exist outside of the app repository. Only the links are deleted.

2. Programmable

Normally creating symbolic links is a tedious process that people must do manually, since every person's system environment is different.

However thanks to Pinokio's self-contained and distributed file system architecture, it is possible to write scripts that will deterministically automate symbolic link creation regardless of what the user's global system environment looks like.

Learn more about the fs.link API here.

3. It "just" works.

The virtual drive abstraction seamlessly blends into whichever apps you already have, and the apps do NOT need to be written in special ways to facilitate virtual drives.

Apps work EXACTLY the same as when they do not use virtual drives, without having to change any code. In fact you can turn the virtual drive feature on and off very easily, simply by including or excluding a single fs.link API call.

Example: Let's say an app at path /PINOKIO_HOM/api/sd has a piece of code that says open("models/checkpoint.pt")

Basically, everything works exactly the same as when you didn't create the virtual drive links, but we still end up with all the benefits that come with virtual drives.

Learn more about the fs.link API here.


Processor

The processor is the CPU of Pinokio. It follows the same scheme all modern CPUs implement (fetch-decode-execute cycle)

  1. Fetch (Loader): The loader engine instantiates the state machine (including the memory as well as self, which refers to its own code)
  2. Decode (Template): The template engine takes a template expression and instantiates it using the current state provided by the loader
  3. Execute (Runner): The runner takes the instantiated request and executes it.

Fetch

The "Fetch" step resolves locally installed scripts and loads them to memory.

fetch.png

Resolve Script

The first step is to resolve the script URI. This involves:

  1. Checking if the specified HTTP git URI is already installed locally.
  2. If it is installed, resolving the local path, so we can access the actual files.

Syntax

{
  "uri": <script_uri>
}

Example

{
  "uri": "https://github.com/cocktailpeanut/blogger.git/index.json"
}

Here's how the above request gets resolved to a local file:

  1. First look for a locally downloaded repository under the /PINOKIO_HOME/api whose git remote matches https://github.com/cocktailpeanut/blogger.git
  2. Let's say we have a locally downloaded repository at /PINOKIO_HOME/api/blogger.git. Then the script resolves the local file at /PINOKIO_HOME/api/blogger.git/index.json.
  3. If not found, it will throw an error.

Note

Pinokio does NOT make a network request to the https path.

Instead, the https URI is simply used for resolving the local paths for already downloaded repositories.

Usage

In practice, most Pinokio users will NOT directly make the "uri" call request programmatically.

Instead, the scripts can be triggered through the UI.

Load Script

The loading stage takes the resolved script file, and actually loads them to memory, so the Pinokio engine can run through the script to execute the commands.

Script written in JSON

Syntax

A script is a JSON (or a JavaScript that returns JSON) file that follows the following syntax:

{
  "daemon": <daemon>,
  "run": <rpc_requests>,
  <key>: <val>,
  <key>: <val>,
  ...
}
Example

Here's an example script that clones a repository and installs some packages.

{
  "run": [{
    "method": "shell.run",
    "params": {
      "message": "git clone https://huggingface.co/spaces/cocktailpeanut/BRIA-RMBG-1.4 app"
    }
  }, {
    "method": "shell.run",
    "params": {
      "venv": "env",
      "path": "app",
      "message": "pip install -r requirements.txt"
    }
  }]
}

In this example, the run array makes 2 shell.run RPC calls:

  1. git clone: Runs git clone https://huggingface.co/spaces/cocktailpeanut/BRIA-RMBG-1.4 app to clone the remote repository to app folder.
  2. install dependencies:
    • Runs pip install -r requirements.txt
    • from the app folder (which was just downloaded from the previous step)
    • to install depencencies to a venv environment at env path

Script written in JavaScript

You can also write JavaScript files to implement a script.

Simply write a node.js async function module that returns a JSON script:

Syntax
module.exports = async (kernel) => {
  return <JSON_RUN_SCRIPT>
}
Example
module.exports = async (kernel) => {
  return {
    "run": [
      {
        "method": "shell.run",
        "params": {
          "message": "git clone https://huggingface.co/spaces/cocktailpeanut/BRIA-RMBG-1.4 app"
        }
      },
      {
        "method": "shell.run",
        "params": {
          "venv": "env",
          "path": "app",
          "message": "pip install -r requirements.txt"
        }
      },
      (kernel.gpu === 'nvidia' ? "pip install xformers" : null)
    ]
  }
}

This is useful when you want to dynamically generate the script based on the kernel state.

  1. Note that it's a node.js module.
  2. It's an async function which takes kernel variable, which lets you access all the system utils and info.
  3. The async function is returning a JSON that follows the Pinokio script syntax.

Note that the last step in the run array either returns pip install xformers or null depending on the kernel.gpu variable:

(kernel.gpu === 'nvidia' ? "pip install xformers" : null)

This will utilize the kernel.gpu variable to detect the gpu, and only run pip install xformers if the gpu is nvidia.

Otherwise it returns null, which will be ignored (skipped) in the execution stage.


Decode

decode.png

A typical Pinokio script contains template expressions.

Without template expressions, you would only be able to run static commands. What we want is to be able to dynamically form requests on the fly, so every run can run a unique request workflow based on the current state of the Pinokio state machine.

Template Interpreter

A Pinokio template expression is a string surrounded by {{ }}, and filled out on the fly when a command is run. Example:

{
  "method": "local.set",
  "params": {
    "name": "{{input}}"
  }
}

So, what can go inside the {{ }} expression?

  1. Any JavaScript evaluation expression: It is recommended to use only simple expressions, but any expression you can run in node.js can be included. For example: {{Buffer.from(input.images[0], "base64")}}
  2. Memory variables: Pinokio exposes certain variables from the memory so you can dynamically run commands based on these memory variables.

The next section lists all the memory variables available for use inside the script template expressions.

Memory Variables

So what kind of variables are available inside the template expression?

Pinokio exposes several system memory variables inside templates. Making use of these variables are essential for writing dynamic (and stateful) scripts.

You can learn more about memory variables in the memory section.

Decode Cycle

The template expressions are instantiated freshly at the beginning of every step in the run array, using the up-to-date memory variables available at the time of parsing.

For example let's say we have a logging script:

{
  "run": [{
    "method": "log",
    "params": {
      "raw": "running instruction {{current}}"
    }
  }, {
    "method": "log",
    "params": {
      "raw": "running instruction {{current}}"
    }
  }, {
    "method": "log",
    "params": {
      "raw": "running instruction {{current}}"
    }
  }]
}

Since the current variable returns the index of the currently executing step in the run array,

  1. First it will run the run[0] step, and print running instruction 0
  2. Then it will run the next step run[1], and print running instruction 1
  3. Finally it will run the final step run[2], and print running instruction 2

Execute

execute.png

Once the request has been instantiated by the decoder, the request is executed.

Script Lifecycle

The script lifecycle is very simple:

{
  "run": [
    <RPC>,
    <RPC>,
    <RPC>,
    <RPC>,
    <RPC>,
    ...
  ]
}
  1. The run array is an ordered list of RPC calls.
  2. Pinokio walks through the run array to run the steps one by one.
  3. Each <RPC> is freshly decoded with the template interpreter before executing.
  4. After each step, the return value of each step is passed down to the next step in the form of input.
  5. Each step can make use of the input variable passed in from the previous step in their template expression to dynamically construct the method to run.
  6. When it reaches the end of the run array, the script halts, and all the processes associated with the script is garbage collected.

run.png

RPC

The RPC (Remote Procedure Call) API lets you actually write various logic to make Pinokio do things.

syntax

{
  "id": <RPC_id>,
  "when": <RPC_condition>,
  "method": <RPC_method>,
  "params": <RPC_params>,
}
  1. <RPC_id>: optional. mark this RPC call with the id of <RPC_id>. a jump RPC call can jump to any step within the run array.
  2. <RPC_condition>: optional. if evaluated to true, run this step. Otherwise go to the next step.
  3. <RPC_method>: The RPC method to call
  4. <RPC_params>: A JSON parameter to pass to the <RPC_method> as payload. The <RPC_params> object will be available as the value {{input}} template expression on the next step.

To learn about all the available RPC APIs, see the script section.

examples

id
{
  "run": [{
    "method": "jump",
    "params": {
      "id": "{{gpu === 'nvidia' ? 'cuda' : 'cpu'}}"
    }
  }, {
    "id": "cpu",
    "method": "shell.run",
    "params": {
      "message": "pip install torch torchvision torchaudio"
    }
  }, {
    "id": "cuda",
    "method": "shell.run",
    "params": {
      "message": "pip install torch torchvision torchaudio --index-url https://download.pytorch.org/whl/cu121"
    }
  }]
}

When the script starts running it encounters a jump instruction that dynamically jumps to either cuda (run[2]) or cpu (run[1]) depending on the GPU.

when
{
  "run": [{
    "when": "{{gpu !== 'nvidia'}}",
    "method": "shell.run",
    "params": {
      "message": "pip install torch torchvision torchaudio"
    }
  }, {
    "when": "{{gpu === 'nvidia'}}",
    "method": "shell.run",
    "params": {
      "message": "pip install torch torchvision torchaudio --index-url https://download.pytorch.org/whl/cu121"
    }
  }]
}

Daemon mode

By default when Pinokio finishes running all the steps inside the run array, every process associated with the script halts, and whatever was in the memory gets cleared out immediately (See script lifecycle).

However, sometimes you may want to keep all the processes running even after Pinokio interpreter has finished executing every step in the run array.

For example imagine launching a web server using Pinokio script:

{
  "run": [{
    "method": "shell.run",
    "params": {
      "message": "python server.py"
    }
  }]
}

The python server.py may launch a server, but when the script finishes running, everything associated with the script will be shut down automatically, including the server.

To keep the server process running, we simply need to specify an additional attribute: daemon:

{
  "daemon": true,
  "run": [{
    "method": "shell.run",
    "params": {
      "message": "python server.py"
    }
  }]
}

By setting daemon to true, Pinokio won't automatically shut down all the associated processes, which means the server will stay running.

The only way to stop the server in this case, is to explicitly stop the script using the script.stop API, or through the Pinokio stop button interface.


Memory

As a pinokio script gets executed step by step, you can update the memory so it can be used in later steps.

input

An input is a variable that gets passed from one RPC call to the next. Not all RPC APIs have a return value, but the ones that do, will pass down the input value to the next step.

run.png

There are two types of input:

  1. Return values between steps: The input value passed into run[1], ... run[run.length-1] steps. Basically, these are values that one step passes on to the next. run[0] can't have this since there is no previous step to run[0].
  2. Initial script launch parameter: The input value passed into run[0].
    • By default, this value will be null for run[0] since there is no "previous step".
    • But it is possible to pass in custom input values to the first step run[0]
      • script.start params: You can launch scripts programmatically using the script.start API. And when you call the method, you can pass an additional params parameter. This will be passed into the first step run[0] as input.
      • pinokio.js menu item params: You can construct the menu items UI in pinokio.js with an array attribute named menu, where each item may contain an href attribute, which will create a menu item that launches a script at the specified URI. You can also pass an additional params object along with the href, and this params object will be passed to the first step run[0] of the script as input when it's launched through the menu item.

Let's take a look at an example:

{
  "run": [{
    "id": "run",
    "method": "gradio.predict",
    "params": {
      "uri": "http://127.0.0.1:7860",
      "path": "/answer_question_1",
      "params": [
        { "path": "https://media.timeout.com/images/105795964/750/422/image.jpg" },
        "Explain what is going on here"
      ]
    }
  }, {
    "method": "log",
    "params": {
      "json2": "{{input.data[0]}}"
    }
  }]
}

In the example above, we are:

  1. Making a request to http://127.0.0.1:7860 using the gradio.predict API.
  2. The return value of the gradio.predict gets passed down to the next step log.
  3. The log takes the input and instantiates the template {{input.data[0]}} and logs the result to the terminal.

args

args is equivalent to the input of the first step (run[0]).

Sometimes you may want to pass in some parameters when launching a script, and make use of the parameter object throughout the entire script.

You can't do this with input because the input variable gets set freshly for every step.

Let's take a look at an example (a file named launch.json):

{
  "run": [{
    "method": "log",
    "params": {
      "json2": "{{input}}"
    }
  }, {
    "method": "log",
    "params": {
      "json2": "{{args}}"
    }
  }]
}

We may launch this script with the following script.start API call:

{
  "run": [{
    "method": "script.start",
    "params": {
      "uri": "launch.json",
      "params": {
        "a": 1,
        "b": 2
      }
    }
  }]
}

This will print:

{"a": 1, "b": 2}
{"a": 1, "b": 2}
  1. The first line is from the first step, using the input value available at run[0].
  2. The second line is from the second step, usin the args value.

Note that the input value and args value will always be the same for run[0].


local

The local variable is every variable prefixed with local.. For example:

Local variables are reset whenever the script finishes running, which means if you run a script once, and run it again, they will always start from scratch.

You can set local variable values with local.set API.


self

The self refers to the script itself.

A run script looks like this:

{
  "daemon": <daemon>,
  "run": <rpc_requests>,
  <key>: <val>,
  <key>: <val>,
  ...
}

Where:

Note that you can have any kind of custom <key>/<value> pairs in the script.

And when you do, you can access them using the self notation.

Let's imagine we have the following script:

{
  "cmds": {
    "win32": "dir",
    "darwin": "ls",
    "linux": "ls"
  },
  "run": [{
    "method": "shell.run",
    "params": {
      "message": "{{self.cmds[platform]}}"
    }
  }]
}

Here, the self.cmds[platform] will resolve to:


uri

The current script uri


cwd

The path of the currently running script


platform

The current operating system. May be one of the following:


arch

The current system architecture. May be one of the following:


gpus

An array of available GPUs on the machine

Example:

["apple"]

gpu

The first available GPU

Example:

apple

current

The current variable points to the index of the currently executing instruction within the run array. For example:

{
  "run": [{
    "method": "log",
    "params": {
      "raw": "running instruction {{current}}"
    }
  }, {
    "method": "log",
    "params": {
      "raw": "running instruction {{current}}"
    }
  }, {
    "method": "log",
    "params": {
      "raw": "running instruction {{current}}"
    }
  }]
}

will print:

running instruction 0
running instruction 1
running instruction 2

next

The next variable points to the index of the next instruction to be executed. (null if the current instruction is the final instruction in the run array):

{
  "run": [{
    "method": "log",
    "params": {
      "raw": "running instruction {{current}}. next instruction is {{next}}"
    }
  }, {
    "method": "log",
    "params": {
      "raw": "running instruction {{current}}. next instruction is {{next}}"
    }
  }, {
    "method": "log",
    "params": {
      "raw": "running instruction {{current}}. next instruction is {{next}}"
    }
  }]
}

Above command will print the following:

running instruction 0. next instruction is 1
running instruction 1. next instruction is 2
running instruction 2. next instruction is null

env

You can access the environment variables of the currently running process with env.

For example, let's say we have set the SD_INSTALL_CHECKPOINT and MODEL_PATH environment variables for the app. We may retrieve them while executing a script, like this:

{
  "run": [{
    "method": "fs.download",
    "params": {
      "uri": "{{env.SD_INSTALL_CHECKPOINT}}",
      "dir": "{{env.MODEL_PATH}}"
    }
  }]
}

Additionally, we may even use the environment variables inside when, effectively determining whether to run an action or not based on environment variables.

For example we may ONLY want to download a file if the environment variable is set:

{
  "run": [{
    "method": "shell.run",
    "params": {
      "message": "git clone https://github.com/AUTOMATIC1111/stable-diffusion-webui app",
    }
  }, {
    "when": "{{env.SD_INSTALL_CHECKPOINT}}",
    "method": "fs.download",
    "params": {
      "uri": "{{env.SD_INSTALL_CHECKPOINT}}",
      "dir": "{{env.MODEL_PATH}}"
    }
  }]
}

In the above script,

  1. If the SD_INSTALL_CHECKPOINT environment variable is set (through ENVIRONMENT, or through other means), the fs.download action will execute properly.
  2. If the SD_INSTALL_CHECKPOINT is NOT set, then the second step will be skipped and the script will complete immediately after the first step.

kernel

The kernel JavaScript API

kernel.exists

Check whether a file or a folder at the specified path exists:

syntax

kernel.exists(...pathChunks)

examples

inside a script
{
  "run": [{
    "when": "{{!kernel.exists(cwd, 'env')}}",
    "method": "script.start",
    "params": {
      "uri": "install.js"
    }
  }]
}

When the template interpreter encounters kernel.exists, it merges all the supplied chunks to construct the full path.

  1. First resolve the path using the cwd variable and the string "env", which will resolve to the env folder in the current directory.
  2. Then it checks if that path exists.
  3. if exists, returns true, otherwise returns false
inside pinokio.js

It is also possible to use the kernel.exists() method inside pinokio.js to dynamically construct the UI.

The UI sidebar gets updated for every step in the run array execution.

module.exports = {
  version: "1.5",
  title: "My App",
  description: "Add description here",
  icon: "icon.png",
  menu: async (kernel) => {
    // we pass 3 chunks: __dirname, "app", and "env" ==> the chunks will be joined to construct the absolute path, and will be checked to see if the path exists.
    let installed = await kernel.exists(__dirname, "app", "env")
    if (installed) {
      // Already installed, display "start" button
      return [{
        icon: "fa-solid fa-plug",
        text: "Start",
        href: "start.js",
      }]
    } else {
      // Not installed, display "install" button
      return [{
        icon: "fa-solid fa-plug",
        text: "Install",
        href: "install.js",
      }]
    }
  }
}

kernel.script.local

Get the local variables of any specified script path

syntax

kernel.script.local(...pathChunks)

example

using relative path
{
  "run": [{
    "method": "script.start",
    "params": {
      "uri": "start.js"
    }
  }, {
    "method": "log",
    "params": {
      "text": "{{kernel.script.local(cwd, 'start.js').url}}"
    }
  }]
}
  1. First run install.js using the script.start API
  2. Then in the next step (log API call), we check {{kernel.script.local(cwd, 'start.js')}}
  3. If the start.js is running, it will return a JSON that contains all its variables as key/value pairs. Otherwise it will return an empty JSON {}
  4. In this case, we assume there's a local variable named url, and can get its value with kernel.script.local(cwd, 'start.js').url
using git path
{
  "run": [{
    "method": "script.start",
    "params": {
      "uri": "https://github.com/cocktailpeanutlabs/moondream2.git/start.js"
    }
  }, {
    "method": "log",
    "params": {
      "json2": "{{kernel.script.local('https://github.com/cocktailpeanutlabs/moondream2.git/start.js')}}"
    }
  }]
}
  1. If https://github.com/cocktailpeanutlabs/moondream2.git/start.js is running: return all local variables for the script
  2. If NOT running: return an empty object {}
inside pinokio.js
module.exports = {
  version: "1.5",
  title: "My App",
  description: "Add description here",
  icon: "icon.png",
  menu: async (kernel) => {

    // Step 1.
    // Get the `local.url` variable inside the script "start.js"
    let url = kernel.local(__dirname, "app", "start.js").url

    // Step 2.
    // If there's a local variable "url", display the "web UI" tab,
    // which links to the url => when clicked, this will open the url
    if (url) {
      return [{
        icon: "fa-solid fa-plug",
        text: "Web UI",
        href: url,
      }]
    }
    // Step 3.
    // if there is no local variable "url",
    // it means the url inside the "start.js" script is not yet ready.
    // so do NOT display the tab to open the url.
    else {
      return [{
        icon: "fa-solid fa-plug",
        text: "Start",
        href: "start.js",
      }]
    }
  }
}

kernel.script.running

syntax

kernel.script.running(...pathChunks)

examples

{
  "run": [{
    "method": "script.start",
    "params": {
      "uri": "install.js"
    }
  }, {
    "method": "log",
    "params": {
      "text": "{{kernel.script.running(cwd, 'install.js')}}"
    }
  }]
}
  1. First it will start the install.js script using the script.start API.
  2. Then in the second step, it checks if the install.js script is running. In this case we have to pass both the cwd (current directory) and the install.js so they can be merged to result in an absolute path.
inside pinokio.js
module.exports = {
  version: "1.5",
  title: "My App",
  description: "Add description here",
  icon: "icon.png",
  menu: async (kernel) => {

    // Step 1.
    // Get the `local.url` variable inside the script "start.js"
    let url = kernel.local(__dirname, "app", "start.js").url

    // Step 2.
    // If there's a local variable "url", display the "web UI" tab,
    // which links to the url => when clicked, this will open the url
    if (url) {
      return [{
        icon: "fa-solid fa-plug",
        text: "Web UI",
        href: url,
      }]
    }
    // Step 3.
    // if there is no local variable "url",
    // it means the url inside the "start.js" script is not yet ready.
    // so do NOT display the tab to open the url.
    else {
      return [{
        icon: "fa-solid fa-plug",
        text: "Start",
        href: "start.js",
      }]
    }
  }
}

_

The _ is the utility variable that lets you easily manipulate data inside template expressions, powered by lodash.

Example:

{
  "run": [{
    "method": "log",
    "params": {
      "raw": "{{_.difference([2, 1], [2, 3])}}"
    }
  }]
}

will print:

1

Another example, where we use the _.sample() method to randomly pick an item from the self.friends variable:

{
  "friends": [
    "HAL 9000",
    "Deep Blue",
    "Watson",
    "AlphaGo",
    "Siri",
    "Cortana",
    "Alexa",
    "Google Assistant",
    "OpenAI",
    "Tesla Autopilot",
    "IBM Watson",
    "Boston Dynamics",
    "IBM Deep Blue",
    "Microsoft Tay",
    "IBM DeepMind",
    "Amazon Rekognition",
    "OpenAI GPT-3"
  ],
  "run": [{
    "method": "log",
    "params": {
      "raw": "random friend: {{_.sample(self.friends)}}"
    }
  }, {
    "method": "log",
    "params": {
      "raw": "random friend: {{_.sample(self.friends)}}"
    }
  }, {
    "method": "log",
    "params": {
      "raw": "random friend: {{_.sample(self.friends)}}"
    }
  }]
}

Above script prints randomly picked items, for example:

random friend: IBM DeepMind
random friend: HAL 9000
random friend: Amazon Rekognition

os

Pinokio exposes the node.js os module through the os variable.

For example, ee can use the os variable to dynamically figure out which platform the script is running on and perhaps shape the commands based on the platform. Example:

{
  "run": [{
    "method": "shell.run",
    "params": {
      "message": "{{os.platform() === 'win32' ? 'dir' : 'ls'}}"
    }
  }]
}

Above script:

  1. runs dir on windows
  2. runs ls on non-windows operating systems (mac, linux)

path

The Node.js path module

examples

{
  "run": [{
    "method": "shell.run",
    "params": {
      "message": "cd {{path.resolve(cwd, 'env')}}"
    }
  }]
}

Script

Pinokio script is a declarative markup that can shell commands, work with files, make network requests, and pretty much everything you need to automatically install and run ANYTHING on a computer.

It is written in JSON, and can also be written in JavaScript (which returns the resulting JSON) in case you need to make them dynamically change.


fs

fs.write

syntax

The fs api provides a simple way to write json, text, or buffer to the file system.

{
  "method": "fs.write",
  "params": {
    "path": <path>,
    <type>: <data>
  }
}

return value

none

examples

Writing JSON

Here's a simple example to write JSON to items.json

{
  "method": "fs.write",
  "params": {
    "path": "items.json",
    "json": {
      "names": [ "alice", "bob", "carol" ]
    }
  }
}

This will result in a file named items.json looking like this:

{"names":["alice","bob","carol"]}


Writing Multi-line JSON

The json type writes the entire JSON in a single line. If we want to write a multiline JSON, use json2 type:

{
  "method": "fs.write",
  "params": {
    "path": "items.json",
    "json2": {
      "names": [ "alice", "bob", "carol" ]
    }
  }
}

This will result in items.json looking like this:

{
  "names": [
    "alice",
    "bob",
    "carol"
  ]
}


Writing text
{
  "method": "fs.write",
  "params": {
    "path": "items.csv",
    "text": "alice,bob,carol"
  }
}

This will result in items.csv that looks like this:

alice,bob,carol


Writing buffer

Converting a base64 string to Buffer and writing to img.png:

{
  "method": "fs.write",
  "params": {
    "path": "img.png",
    "buffer": "{{Buffer.from(input.images[0], 'base64')}}"
  }
}

fs.read

syntax

The fs api provides a simple way to read from files.

{
  "method": "fs.read",
  "params": {
    "path": <path>,
    "encoding": <encoding>
  }
}

Internally, the API calls the fs.readFile node.js method:

fs.readFile(params.path, params.encoding)

return value

examples

example (read img.png and print its base64 encoded string):

{
  "run": [{
    "method": "fs.read",
    "params": {
      "path": "img.png",
      "encoding": "base64"
    }
  }, {
    "method": "log",
    "params": {
      "raw": "data:image/png;base64,{{input}}"
    }
  }]
}

fs.rm

syntax

The fs.rm API deletes a file or a folder at the specified path

{
  "method": "fs.rm",
  "params": {
    "path": <path>
  }
}

return value

none

examples

example: Delete the folder app in the current directory.

{
  "run": [{
    "method": "fs.rm",
    "params": {
      "path": "app"
    }
  }]
}

fs.copy

syntax

The fs.copy API copies a file or a folder at src to dest

{
  "method": "fs.copy",
  "params": {
    "src": <source_path>,
    "dest": <destination_path>
  }
}

return value

none

examples

example: Copying hello.txt to world.txt

{
  "run": [{
    "method": "fs.copy",
    "params": {
      "src": "hello.txt",
      "dest": "world.txt"
    }
  }]
}

example: Copying the folder app to a new folder api recursively

{
  "run": [{
    "method": "fs.copy",
    "params": {
      "src": "app",
      "dest": "api"
    }
  }]
}

fs.download

The fs.download downloads a file to a specified path or directory. If the path does not exist, it is created first if possible.

syntax

{
  "method": "fs.download",
  "params": {
    "uri": <uri>,
    <type>: <path>
  }
}

return value

none

examples

download file as path

example: Download https://via.placeholder.com/600/92c952 to a file named placeholder.png

{
  "run": [{
    "method": "fs.download",
    "params": {
      "url": "https://via.placeholder.com/600/92c952",
      "path": "placeholder.png"
    }
  }]
}
download file into dir

example: Download the file at https://huggingface.co/stabilityai/sdxl-turbo/resolve/main/sd_xl_turbo_1.0.safetensors?download=true under the models folder

{
  "run": [{
    "method": "fs.download",
    "params": {
      "url": "https://huggingface.co/stabilityai/sdxl-turbo/resolve/main/sd_xl_turbo_1.0.safetensors?download=true",
      "dir": "models"
    }
  }]
}
download files into dir

example: Download multiple files into a dir

{
  "run": [{
    "method": "fs.download",
    "params": {
      "uri": [
        "https://huggingface.co/justimyhxu/GRM/blob/main/grm_u.pth",
        "https://huggingface.co/cocktailpeanut/sv3/blob/main/sv3d_p.safetensors"
      ],
      "dir": "app/checkpoints"
    }
  }]
}

fs.link

The fs.link API provides an easy way to store data outside of the repository through a mechanism called Pinokio Virtual Drive.

Virtual drives let you store data outside of applications and reference them from the apps without changing anything. Useful for many things, such as:

  1. Storing files that persist across multiple installs (Similar to Docker Volumes)
  2. Sharing files across multiple apps (such as AI model .safetensor files)
  3. Storing all the library files (such as pytorch) in a deduplicated manner

Learn more about Virtual Drives here

Here are the operations supported by the fs.link API:

  1. folder linking: link any folder paths within the current repository to corresponding virtual drive paths
  2. peer linking: optionally, you can create a shared drive among multiple applications by declaring them as peer drives. It works the same sa folder linking, except it first checks if there's already an existing peer drive before creating one. If there is one already, the discovered peer drive is used instead of creating one.
  3. venv linking: a special link method, which automatically links every installed python package inside a venv environment to each corresponding drive path.
    • useful for saving disk space by automatically deduplicating redundant packages (such as pytorch, etc.) across multiple apps.

1. folder linking

link_folder.png

You can link folders to virtual drive counterparts with:

{
  "method": "fs.link",
  "params": {
    "drive": {
      <drive_folder_path>: <actual_folder_path>,
      <drive_folder_path>: <actual_folder_path>,
      ...
    }
  }
}

Every fs.link call creates a virtual drive designated for the current repository, and then links the specified virtual paths to the actual path counterparts.

Here's an example:


// /PINOKIO_HOME/api/APP1/install.json

{
  "method": "fs.link",
  "params": {
    "drive": {
      "checkpoints": "app/models/checkpoints",
      "clip": "app/models/clip",
      "vae": "app/models/vae"
    }
  }
}
  1. The fs.link call first creates a virtual drive for the current repository (/PINOKIO_HOME/api/APP1)
  2. It then merges all the files inside app/models/checkpoints, app/models/clip, app/models/vae into the corresponding virtual drive folders (checkpoints, clip, vae)
  3. Finally, it creates symbolic links to link the actual paths to the virtual drive paths:
    • from app/models/checkpoints, app/models/clip, and app/models/vae to
    • to the created virtual drive paths for this repository at checkpoints, clip, and vae each.

Let's walk through each step one by one.

NOTE

The following sections simply explain how the fs.link API works internally, and not something you need to do yourself. All these steps are taken care of by the fs.link API automatically.

Just read to understand what exactly happens when you run the fs.link API.

Step 1. Drive Creation

The fs.link first creates a virtual drive for the current repository. A unique folder for the current repository is created under /PINOKIO_HOME/drive/drives/peers.

Here's an example:

/PINOKIO_HOME
  /drive
    /drives
      /peers  
        /d1711553147861       <= virtual drive
Step 2. Create virtual drive folders

The next step is to create the virtual drive folders from the keys under the params.drive, in this case:

We end up with a virtua drive at the following paths:

/PINOKIO_HOME
  /drive
    /drives
      /peers  
        /d1711553147861       <= virtual drive
          /checkpoints
          /clip               
          /vae
Step 3. Merge Files into Drives

Next, if there were any existing files inside the application folders, we need to merge them into the virtual drive folders, since we are about to turn these folders into symbolic links.

The merging is necessary, because otherwise all those files will be lost during the process, since the original folders will turn into symbolic links in the next step.

Pinokio uses a merging algorithm to merge the files at path:

into the virtual drive folders:

At the end of this step, the original application folders will be empty, and all the files will now be in the virtual drive folders.

Step 4. Create Links

Finally we finish the process by linking the application folders to the corresponding drive folders:

/PINOKIO_HOME/api/APP1/app/models/checkpoints => /PINOKIO_HOME/drive/drives/peers//d1711553147861/checkpoints
/PINOKIO_HOME/api/APP1/app/models/clip        => /PINOKIO_HOME/drive/drives/peers//d1711553147861/clip
/PINOKIO_HOME/api/APP1/app/models/vae         => /PINOKIO_HOME/drive/drives/peers//d1711553147861/vae

The app will work exactly the same as before, because when the app tries to access the application folders, they will be redirected by the symbolic links to the virtual drive folders.

Now if we download a file named sd_xl_turbo_1.0_fp16.safetensors into /PINOKIO_HOME/api/APP1/app/models/checkpoints, the actual file will be stored in the linked virtual drive folder like this:

/PINOKIO_HOME
  /api
    /APP1
      /app
        /models
          /checkpoints => symbolic liink to /drive/drives/peers/d1711553147861/checkpoints
    /APP2
    /APP3
    ...
  /drive
    /drives
      /peers
        /d1711553147861
          /checkpoints
            sd_xl_turbo_1.0_fp16.safetensors
        ...
  /logs
  /bin
  /cache

However you will still be able to access the sd_xl_turbo_1.0_fp16.safetensors file as if it's inside /PINOKIO_HOME/api/APP1/app/models/checkpoints thanks to the symbolic link system.

2. peer linking

link_peer.png

Now, what if we want to share a single virtual drive among multiple apps? For example, let's say we have 3 different Stable Diffusion apps named Stable-Diffusion-WebUI, ComfyUI, and Fooocus, and they all use the same AI model files.

How can we create a virtual drive so it can be shared by all 3 apps?

We can achieve this by declaring peers when creating a virtual drive with fs.link:

{
  "method": "fs.link",
  "params": {
    "drive": {
      <drive_folder_path>: <actual_folder_path>,
      <drive_folder_path>: <actual_folder_path>,
      ...
    },
    "peers": <peers>
  }
}

The only difference from plain folder linking is that there's a peer array.

When a peers array is declared, the fs.link API runs the following logic first BEFORE attempting to create its own virtual drive folders:

  1. Loop through the peers array, and for each peer check if there is any virtual drive already created.
  2. If a virtual drive is found for a peer, use that drive instead of creating a new drive.
  3. If no virtual drive is found for any of the specified git repositories in the peers array, create a virtual drive using the folder linking method.

Let's take a look at a specific example, where we will write scripts for fooocus, stable-diffusion-webui, and comfyui so they all declare one another as peers:

      },
      "peers": [
        "https://github.com/cocktailpeanutlabs/automatic1111.git",
        "https://github.com/cocktailpeanutlabs/comfyui.git"
      ]
    }
  }]
}

      "peers": [
        "https://github.com/cocktailpeanutlabs/comfyui.git",
        "https://github.com/cocktailpeanutlabs/fooocus.git"
      ]
    }
  }]
}

Install script in https://github.com/cocktailpeanutlabs/comfyui.git

{
  "run": [{
    "method": "shell.run",
    "params": {
      "message": "git clone https://github.com/comfyanonymous/ComfyUI.git app"
    }
  }, {
    "method": "fs.link",
    "params": {
      "drive": {
        "checkpoints": "app/models/checkpoints",
        "clip": "app/models/clip",
        "clip_vision": "app/models/clip_vision",

        "vae": "app/models/vae"
      },
      "peers": [
        "https://github.com/cocktailpeanutlabs/automatic1111.git",
        "https://github.com/cocktailpeanutlabs/fooocus.git"
      ]
    }
  }]
}

Each of the three scripts declares the rest 2 as the peers:

peers.png

So how does this work in practice?

  1. When any of these three scripts are run for the first time, there will be no existing "peer drive", therefore a new virtual drive will be created for the respository.
  2. Then later if you run one of the other scripts, it will first run the peers check to discover any existing peer.
  3. Since a peer virtual drive was already created in step 1, the virtual drive created in step 1 will used when running the rest of the fs.link folder linking, instead of creating a new drive.

3. venv linking

link_venv.png

One of the most frequently encountered use cases is dealing with redundant packages installed into venv environments across multiple apps.

Let's imagine the following scenario where we have 3 different apps APP1, APP2, and APP3, each with its own independent venv environment:

/PINOKIO_HOME
  /api
    /APP1
      requirements.txt
      app.py
      /venv
        /lib
          /python3.10
            /site-packages
              /torch
              /accelerate
              /xformers
    /APP2
      requirements.txt
      app.py
      /venv
        /lib
          /python3.10
            /site-packages
              /torch
              /accelerate
              /xformers
    /APP3
      requirements.txt
      app.py
      /venv
        /lib
          /python3.10
            /site-packages
              /torch
              /accelerate
              /xformers
  1. ALL of these apps have the same redundant packages installed (torch, accelerate, xformers, etc.)
  2. However this is how venv is supposed to work. The whole point of venv is to isolate environments, so each environment is not supposed to know about other environments on the same machine.
  3. It would still be nice to take advantage of the isolated environments we get from venv, while removing redundancy, so we can save some disk space.

And this is where the venv linking comes in.

For this special use case, there's an automated way to create virtual drives, with just one line.

{
  "method": "fs.link",
  "params": {
    "venv": <venv_path>
  }
}

This will:

  1. look into all the pip packages installed into the venv at <venv_path>
  2. automatically create virtual drives for each unique version of the installed packages
  3. automatically merge the package files inside the <venv_path> into the virtual drive paths
  4. automatically create symbolic links from all the folders inside the original <venv_path> site-packages folder pointing to the automatically created virtual drive folders.

Unlike the folder linking method which creates a unique virtual drive for every repository, there is a single centralized pip drive organized as follows:

/PINOKIO_HOME
  /drive
    /drives
      /pip
        /accelerate
          /0.20.3
          /0.21.0
          /0.28.0
        /torch
          /2.1.0
          /2.2.2
        ...

Basically, every unique version of a unique library installed has its unique folder path.

When you call fs.link on a venv environment path, here's what happens:

  1. Pinokio scans through the specified venv folder to find all installed packages
  2. Then for every package in the venv, it looks up /PINOKIO_HOME/drive/drives/pip/<package_name>/<version> to check if it already exists in the virtual drive
  3. If it already exists, just use that one
  4. If it does NOT exist, create the library's version folder (for example /PINOKIO_HOME/drive/drives/pip/torch/2.3.0), move all files into the drive, and create a symbolic link

This way, each library path in the venv will be nothing more than a symbolic link to the created drive path.

Here's what the end result may look like for the original 3 apps example from above:

/PINOKIO_HOME
  /drive
    /drives
      /pip
        /accelerate
          /0.20.3
          /0.21.0
          /0.28.0
        /torch
          /2.1.0
          /2.2.2
        /xformers
          /0.0.25
          /0.0.24
        ...
  /api
    /APP1
      requirements.txt
      app.py
      /venv
        /lib
          /python3.10
            /site-packages
              /torch          => link to /PINOKIO_HOME/drive/drives/pip/torch/2.2.2
              /accelerate     => link to /PINOKIO_HOME/drive/drives/pip/accelerate/0.28.0
              /xformers       => link to /PINOKIO_HOME/drive/drives/pip/xformers/0.0.25
    /APP2
      requirements.txt
      app.py
      /venv
        /lib
          /python3.10
            /site-packages
              /torch          => link to /PINOKIO_HOME/drive/drives/pip/torch/2.2.2
              /accelerate     => link to /PINOKIO_HOME/drive/drives/pip/accelerate/0.28.0
              /xformers       => link to /PINOKIO_HOME/drive/drives/pip/xformers/0.0.25
    /APP3
      requirements.txt
      app.py
      /venv
        /lib
          /python3.10
            /site-packages
              /torch          => link to /PINOKIO_HOME/drive/drives/pip/torch/2.2.2
              /accelerate     => link to /PINOKIO_HOME/drive/drives/pip/accelerate/0.28.0
              /xformers       => link to /PINOKIO_HOME/drive/drives/pip/xformers/0.0.25
  1. Note that the /torch, /accelerate, and xformers folders are all pointing to the shared virtual drive folders. This is already saving tons of disk space by removing the redundancy.
  2. At the same time, each app works EXACTLY the same as before because these are symbolic links, and they all behave as if these pip packages are actually stored in each app's venv site-packages folders (but in reality they are just symbolic links pointing to the shared pip virtual drive)

jump

By default, Pinokio steps through all the requests in the run array and halts at the end.

However you can implement looping, which will let you build all kinds of interesting perpetual workflows.

syntax

{
  "method": "jump",
  "params": {
    <key>: <value>,
    "params": <params>
  }
}

return value

none

examples

jump to index
{
  "run": [{
    "method": "jump",
    "params": {
      "index": 2
    }
  }, {
    "method": "log",
    "params": {
      "raw": "hello"
    }
  }, {
    "method": "log",
    "params": {
      "raw": "world"
    }
  }]
}

This will print:

world
jump to id
{
  "run": [{
    "method": "jump",
    "params": {
      "id": "w"
    }
  }, {
    "method": "log",
    "params": {
      "raw": "hello"
    }
  }, {
    "id": "w",
    "method": "log",
    "params": {
      "raw": "world"
    }
  }]
}

This will print:

world
jump with params
{
  "run": [{
    "method": "jump",
    "params": {
      "id": "w",
      "params": {
        "answer": 42
      }
    }
  }, {
    "method": "log",
    "params": {
      "raw": "hello"
    }
  }, {
    "id": "w",
    "method": "log",
    "params": {
      "raw": "the meaning of life, the universe, and everything: {{input.answer}}"
    }
  }]
}

Above script will:

  1. first encounter the jump step, which jumps to the id of "w", which happens to be the last step in the run array (run[2]).
  2. in addition to jumping, it will pass the params of { "answer": 42 }.
  3. In the last step, the params passed in from the previous step will be available as the variable input, and the template expression {{input.answer}} will evaluate to 42

So it will print:

the meaning of life, the universe, and everything: 42
loop

You can use the jump api to loop.

{
  "run": [{
    "id": "start",
    "method": "local.set",
    "params": {
      "counter": "{{local.counter ? local.counter+1 : 1}}"
    }
  }, {
    "method": "log",
    "params": {
      "raw": "{{'' + local.counter + ' is ' + (local.counter % 2 === 0 ? 'even' : 'odd')}}"
    }
  }, {
    "method": "jump",
    "params": {
      "id": "{{local.counter < 20 ? 'start' : 'end'}}"
    }
  }, {
    "id": "end",
    "method": "log",
    "params": {
      "raw": "finished!"
    }
  }]
}
  1. sets local.counter to 1
  2. prints whether it's even or odd
  3. jumps back to start if the local.counter is less than 20
  4. otherwise jump to end.

gradio

gradio.predict

syntax

{
  "method": "gradio.predict",
  "params": {
    "uri": <uri>,
    "path": <path>,
    "params": <params>
  }
}

return value

examples

Let's make a request to a gradio endpoint:

{
  "run": [{
    "method": "gradio.predict",
    "params": {
      "uri": "http://127.0.0.1:7860",
      "path": "/answer_question_1",
      "params": [
        { "path": "https://media.timeout.com/images/105795964/750/422/image.jpg" },
        "Explain what is going on here"
      ]
    }
  }, {
    "method": "log",
    "params": {
      "json2": "{{input.data[0]}}"
    }
  }]
}

If the endpoint returns { "data": ["A man is drinking coffee"] }, the script will print:

A man is drinking coffee.

local

local.set

Sets a value at an object path (can be a key path, and the key path can also include an array index)

syntax

{
  "method": "local.set",
  "params": {
    <key>: <val>,
    ...
  } 
}

Sets the local variable attributes for the <key> as <val>.

  1. The local variable will be available from the memory as long as the script is running.
  2. When the script finishes running, the local variables will be gone.

return value

none

examples

simple key/val

The following comand sets the local variables local.name.first and local.animal:

{
  "run": [{
    "method": "local.set",
    "params": {
      "name": "Alice",
      "animal": "dog"
    }
  }, {
    "method": "log",
    "params": {
      "text": "{{local.name + ' ' + local.animal}}"
    }
  }]
}

This will set the local variables name and animal, and will print:

Alice dog

log

syntax

{
  "method": "log",
  "params": {
    <type>: <data>
  }
}

return value

    "params": {
      "hello": "world"
    }
  }, {
    "method": "log",
    "params": {
      "text": "{{local.hello}}"
    }
  }]
}

will print:

world
printing JSON

Passing the json attribute (instead of raw) will print JSON

{
  "run": [{
    "method": "local.set",
    "params": {
      "hello": "world"
    }
  }, {
    "method": "log",
    "params": {
      "json": "{{local}}"
    }
  }]
}

will print:

{"hello":"world"}
printing multiline JSON

Passing the json2 attribute will print JSON, but in multiple lines:

{
  "run": [{
    "method": "local.set",
    "params": {
      "hello": "world",
      "bye": "world"
    }
  }, {
    "method": "log",
    "params": {
      "json2": "{{local}}"
    }
  }]
}

will print the object in multiple lines:

{
  "hello": "world"
  "bye": "world"
}

net

  "params": {
    "url": <url>,
    "method": <method>,
    "headers": <request_headers>,
    "data": <request_data>
  }
}

The net api internally makes use of the axios library, so for a full reference of the API refer to the Axios documentation here

Internally, the above JSON script calls the following axios command:

let response = await axios({
  "url": <url>,
  "method": "get"|"post"|"delete"|"put",
  "headers": <request headers>,
  "data": <request body>,
}).then((res) => {
  return res.data
})

    "method": "script.return",
    "params": {
      "response": "{{args.a + ' + ' + args.b}}"
    }
  }]
}

This will print:

{
  "a": "hello",
  "b": "world"
}
hello world
{
  "a": "hello",
  "b": "world"
}
{
  "response": "hello + world"
}

This is because when this script is called with the params of { "a": "hello", "b": "world" }:

  1. In the first step, BOTH input and args will be { "a": "hello", "b": "world" }
    • input is the params passed in from the immediately previous step, which means the input value will be different for every step.
    • args is the params passed in to the script itself, which means the args (if it exists), will be the same value throughout the entire script execution.
  2. In the second step, the args is still available as the same value, therefore prints hello world
  3. In the third step, the args is the same again, so prints the same args object
  4. The last step (script.return) returns the value { "response": "hello + world" }
  5. Then the original index.json goes on to the next step with the return value set to input, so the log method prints { "response": "hello + world" }

because:

  1. the args will be { "a": "hello", "b": "world" } throughout the entire callee.json script execution
  2. the input value
remote script call

"remote script" does NOT mean it makes a request to a remote server.

Remote script simply means a script downloaded from a remote server. In this case, the uri can be a git URI scheme that points to a file. For example https://github.com/cocktailpeanutlabs/comfyui.git/install.js.

Here's an example. Let's say we have a script at /PINOKIO_HOME/api/myapp/install.json:

{
  "run": [{
    "method": "script.start",
    "params": {
      "uri": "https://github.com/cocktailpeanutlabs/torch.git/install.js",
      "branch": "main",
      "params": {
        "venv": "{{path.resolve(cwd, 'env')}}"
      }
    }
  }]
}

When this script runs, here's what happens:

  1. First, internally Pinokio runs script.download to clone the repository at https://github.com/cocktailpeanutlabs/torch.git
  2. Then it switches the git branch to main.
  3. Then it starts the script install.js with a params of { "venv": "{{path.resolve(cwd, 'env')}}" }, which resolves to the env folder of the current script
    • Note that the cwd is the path of the original script: /PINOKIO_HOME/api/myapp (not the path for the repository just downloaded)
    • This means the actual params that gets passed will look something like { "venv": "/PINOKIO_HOME/api/myapp/install.json" }

    }
  }, {

    "params": {
      "json2": "{{input.response}}"
    }

    }
  }]
}

note that script.return itself does NOT have a return value because its function is to return the value back to the caller script.


shell

shell.run

syntax

The shell.run command starts an instant shell, runs the specified commands, and closes the shell.

{
  "method": "shell.run",
  "params": {
    "message": <message>,
    "path": <path>,
    "env": <env>,
    "venv": <venv_path>,
    "conda": <conda_config>,
    "on": <shell_event_handler>,
    "sudo": <sudo>,
    "cache": <cache>
  }
}

return value

Example:

When running:

{
  "daemon": true,
  "run": [{
    "method": "shell.run",
    "params": {
      "message": "python app.py",
      "venv": "env",
      "on": [{
        "event": "/http:\/\/[0-9.:]+/",
        "done": true
      }]
    }
  }, {
    "method": "local.set",
    "params": {
      "url": "{{input.event[0]}}"
    }
  }, {
    "method": "log",
    "params": {
      "raw": "Running on {{local.url}}"
    }
  }]
}

The first step will return input as the following object:

examples

message

You can either pass one message (string), or multiple messages (array):

Single message

If the message attribute is a single string, it simply enters that line into the shell.

{
  "run": [{
    "method": "shell.run",
    "params": {
      "venv": "env",
      "message": "pip install -r requirements.txt"
    }
  }]
}
Multiple messages

If the message attribute is an array, it executes the commands in sequence.

{
  "run": [{
    "method": "shell.run",
    "params": {
      "venv": "env",
      "message": [
        "pip install -r requirements.txt",
        "pip install torch gradio"
      ]
    }
  }]
}
path

The path attribute is used to specify the path from which the shell starts.

{
  "run": [{
    "method": "shell.run",
    "params": {
      "path": "app",
      "message": "python app.py"
    }
  }]
}

In this example, the shell starts from the app folder, basically running python for the app/app.py file.

env

The env attribute can be used to inject custom environment variables when starting the shell.

{
  "run": [{
    "method": "shell.run",
    "params": {
      "env": {
        "PYTORCH_ENABLE_MPS_FALLBACK": "1"
      },
      "message": "python app.py"
    }
  }]
}

In this example, the PYTORCH_ENABLE_MPS_FALLBACK environment variable is set to "1" before running python app.py.

venv

The venv attribute is used to declaratively activate a venv environment with just 1 line.

{
  "run": [{
    "method": "shell.run",
    "params": {
      "venv": ".env",
      "message": "python app.py"
    }
  }]
}

With just one line above, it either creates a venv at path .env (if it doesn't exist yet), and activates the environment for this specific shells session.

Basically, when the .env already exists, it's equivalent to:

source .env/bin/activate
python app.py

And when the .env doesn't exist, it's equivalent to:

python -m venv .env
source .env/bin/activate
python app.py

But you don't have to worry about any of this since with just one line "venv": ".env" this is handled automatically.

Note that the venv environment is ephemeral to the shell.run call, so when that shell session ends, the venv is no longer active.

For example:

{
  "run": [{
    "method": "shell.run",
    "params": {
      "venv": "env1",
      "message": "python app.py"
    }
  }, {
    "method": "shell.run",
    "params": {
      "venv": "env2",
      "message": "python app.py"
    }
  }]
}

in the example above, the first shell.run runs in env1 environment, whereas the second shell.run runs in env2 environment. The two shell sessions are completely independent from each other.

conda

The conda attribute

1. default is base

By default if you do not specify any conda attribute in shell.run, it will automatically activate the Pinokio-sandboxed base environment.

Even if you have a globally installed conda, it will NOT use your system-wide base environment, but use Pinokio's own base environment. This is to ensure everything works exactly the same for every user in every system.

For example the following will automatically activate the Pinokio base environment before starting the shell (which you can find in /PINOKIO_HOME/bin/miniconda):

{
  "run": [{
    "method": "shell.run",
    "params": {
      "message": "python app.py"
    }
  }]
}
2. specifying custom conda environment path

You can also create and/or activate a custom conda environment at a specific path:

{
  "run": [{
    "method": "shell.run",
    "params": {
      "conda": "conda_env",
      "message": "python app.py"
    }
  }]
}

Above script will:

  1. First check if there's a conda environment at path conda_env (relative to the current folder)
  2. If there is one, activate the environment
  3. If there is no conda environment there, create a conda environment at the location and activate it.
  4. Finally start the shell session and run the command python app.py
3. specifying custom conda environment by name

You can also create/activate a conda environment by name. In this case you will need to use the object syntax instead of using string.

The difference is, instead of storing the conda environment at a specific path, the environment will be stored inside /PINOKIO_HOME/bin/miniconda.

{
  "run": [{
    "method": "shell.run",
    "params": {
      "conda": {
        "name": "conda_env",
      },
      "message": "python app.py"
    }
  }]
}

Writing scripts that create custom conda environments by name is not recommended, because of potential name collision issues. If you really must use conda, create custom conda environments using path instead.

4. skip activating any conda environment

Normally you probably don't want to do this, but you can even avoid the default option of activating the base conda environment if you want.

{
  "run": [{
    "method": "shell.run",
    "params": {
      "conda": {
        "skip": true
      },
      "message": "python app.py"
    }
  }]
}
5. custom conda environment with custom python

You can create a custom conda environment with a custom python version using the conda.python attribute:

{
  "run": [{
    "method": "shell.run",
    "params": {
      "conda": {
        "path": "custom_python_conda_env",
        "python": "python=3.11"
      },
      "message": "python app.py"
    }
  }]
}
on

The on attribute lets you implement a realtime shell parser.

  1. Monitor the shell content in realtime
  2. When one of the specified events match, move on to the next step along with the matched pattern as input.event
  3. Additionally, specify whether to kill the shell process (kill) or keep it running (done)
1. keep the shell process running and move on
{
  "daemon": true,
  "run": [{
    "method": "shell.run",
    "params": {
      "message": "python app.py",
      "venv": "env",
      "on": [{
        "event": "/http:\/\/[0-9.:]+/",
        "done": true
      }]
    }
  }, {
    "method": "local.set",
    "params": {
      "url": "{{input.event[0]}}"
    }
  }]
}

Explanation:

  1. method: Run a command with shell.run that starts a web server (python app.py)
  2. venv: The shell is automatically activated to the venv at path env (relative path).
  3. on: The on handler takes an array of multiple possible events (In this case just one event).
    • event The shell keeps running until the regular expression /http:\/\/[0-9.:]+/,
    • done: Since done: true is set, the behavior is to move onto the next RPC call while keeping the shell process running. This is needed because we want the python app.py process to keep running (it's a web server).
  4. In the next step local.set, the input variable passed in from the previous step contains { id, stdout, event } attributes.
1. kill the shell process and move on

Example:

{
  "daemon": true,
  "run": [{
    "method": "shell.run",
    "params": {
      "message": "python app.py",
      "venv": "env",
      "on": [{
        "event": "/http:\/\/[0-9.:]+/",
        "kill": true
      }]
    }
  }, {
    "method": "local.set",
    "params": {
      "url": "{{input.event[0]}}"
    }
  }]
}

Same as the done: true case, but in this case, the kill: true is set, therefore when the event match happens, the shell session as well as all its associated processes are shut down before moving onto the next step.

sudo

Run shell commands in admin mode.

{
  "run": [{
    "method": "shell.run",
    "params": {
      "sudo": true,
      "message": "reg add HKLM\\SYSTEM\\CurrentControlSet\\Control\\FileSystem /v LongPathsEnabled /t REG_DWORD /d 1 /f",
    }
  }]
}

In this case we are trying to set the registry value, which needs to be run in admin mode, and we can simply pass the sudo: true option to achieve this.


UI

The RPC API lets you automatically run things. But we also need a user interface to interact with them.

Just like scripts, you can write a UI using nothing but JSON (or JavaScript).

components

For every project, you just need to think about two UI components:

  1. shortcut: displayed on the home page.
  2. app: The actual UI layout.

shortcut

ui0.png

app

ui1.png

pinokio.js

Building a UI requires only a single file named pinokio.js. Simply place a file named pinokio.js in the project root folder.

The pinokio.js file describes both:

  1. Shortcut UI
  2. App UI

What if there is no pinokio.js file?

In this case, Pinokio will do its best to generate a minimal UI for you:

  1. The shortcut UI will simply display the folder name as its title, and a default icon.
  2. The app UI will display all js or json files inside the project root folder.

But in most cases you will want to write a simple pinokio.js file to build your own custom UI.

syntax

module.exports = {
  "version": <script_schema_version>,
  "title": <title>,
  "icon": <icon>,
  "description": <description>,
  "menu": <menu>,
  "pre": <pre>,
  "start": <start>
}

examples

Prerequisite apps

Let's say an app needs Ollama to run.

We can direct the user to install Ollama before installing the app, using the <pre> syntax in pinokio.js:

module.exports = {
  version: "2.0",
  title: "LLM App",
  pre: [{
    icon: "ollama.png",
    title: "Ollama",
    description: "Get up and running with large language models.",
    href: "https://ollama.com/"
  }],
  ...
}

When this is downloaded, the user will be shown the following Prerequisites screen BEFORE the install screen:

prerequisites.png

Static menu

Here's a UI script for generating a minimal launcher UI:

module.exports = {
  version: "2.0",
  title: "Test Launcher",
  description: "This is for testing a test launcher",
  icon: "icon.png",
  menu: [{
    icon: "fa-brands fa-google",  // see https://fontawesome.com/icons/google?f=brands&s=solid
    text: "Open Google",
    href: "https://google.com",
  }, {
    icon: "fa-brands fa-discord",
    text: "Open Discord in New Window",
    href: "https://discord.gg/TQdNwadtE4",
    popout: true    // "popout": true => opens the link in an external browser instead of as a Pinokio tab.
  }]
}

Dynamic menu

The sidebar menu is automatically re-rendered every time a step in the currently running script finishes.

This means you can write the pinokio.js file so it automatically displays relevant items in realtime.

dynamicmenu.gif

For example, when the app is running, you may want to display a link to open the actual web UI. Or when the app is not running, you may want to display a "Start" button instead.

We can achieve this type of dynamic menu rendering by using a function instead of array. Instead of setting a static menu array, set the menu as an async function that takes kernel and info as an arguments.

You can use the info variable to get various types of status information about the files and scripts:

Check out an example below, where it makes use of the info API to determine whether install.json or start.json scripts are running, and if they are, get the local variable in memory, etc.

const path = require("path")
module.exports = {
  version: "2.0",
  title: "InvokeAI",
  description: "Generative AI for Professional Creatives",
  icon: "icon.jpeg",
  menu: async (kernel, info) => {
    /**********************************************************************************************
      info has 4 methods (where `filepath` may be a relative path or an absolute path.):
        - info.local(filepath): get the local variable object of a script running at `filepath`.
        - info.running(filepath): get the running status of a script at `filepath`.
        - info.exists(filepath): check if a file exists at `filepath`.
        - info.path(filepath): get the absolute path of a `fileapth`.
    **********************************************************************************************/
    let installing = info.running("install.json")
    let installing = info.running("install.json")
    let installed = info.exists("app/env")
    if (installing) {
      return [{ icon: "fa-solid fa-plug", text: "Installing...", href: "install.json" }]
    } else if (installed) {
      let running = info.running("start.json")
      if (running) {
        let memory = info.local("start.json")
        if (memory && memory.url) {
          return [
            { icon: "fa-solid fa-rocket", text: "Web UI", href: memory.url },
            { icon: "fa-solid fa-terminal", text: "Terminal", href: "start.json" },
            { icon: "fa-solid fa-rotate", text: "Update", href: "update.json" },
          ]
        } else {
          return [
            { icon: "fa-solid fa-terminal", text: "Terminal", href: "start.json" },
            { icon: "fa-solid fa-rotate", text: "Update", href: "update.json" },
          ]
        }
      } else {
        return [{
          icon: "fa-solid fa-power-off",
          text: "Start",
          href: "start.json",
        }, {
          icon: "fa-solid fa-rotate", text: "Update", href: "update.json"
        }, {
          icon: "fa-solid fa-plug", text: "Reinstall", href: "install.json"
        }, {
          icon: "fa-solid fa-broom", text: "Factory Reset", href: "reset.json"
        }]
      }
    } else {
      return [
        { icon: "fa-solid fa-plug", text: "Install", href: "install.json" },
        { icon: "fa-solid fa-rotate", text: "Update", href: "update.json" }
      ]
    }
  }
}

Based on the determined app status, the dynamic menu function can generate menu items.

  1. check whether a file/folder exists at a path: info.exists()
  2. check if a script at a specified path is running: info.running()
  3. get the local variables object for a script at specified path: info.local()

Nested menu

You can nest the menu array into another menu (up to level 2)

nestedmenu.gif

module.exports = {
  title: "Test Launcher",
  description: "This is for testing a test launcher",
  icon: "icon.png",
  menu: [{
    icon: "fa-solid fa-download",
    text: "Download Models",
    menu: [
      { text: "Download by URL", icon: "fa-solid fa-download", href: "download.html?raw=true" },
      { text: "SDXL", icon: "fa-solid fa-download", href: "download-sdxl.json", mode: "refresh" },
      { text: "SDXL Turbo", icon: "fa-solid fa-download", href: "download-turbo.json", mode: "refresh" },

      { text: "Playground2.5", icon: "fa-solid fa-download", href: "download-playground.json", mode: "refresh" },

    ]
  }]
}

Auto-execution

Using the default attribute, it is possible to implement auto-executing scripts.

For example, let's say we want the following behavior:

module.exports = {
  title: "Auto Launcher",
  icon: "icon.png",
  menu: async (kernel, info) => {
    if (info.exists("app/env")) {
      // already installed. select the "start.js", automatically running `start.js`
      return [{
        text: "Install",
        href: "install.js"
      }, {
        default: true,
        text: "Start",
        href: "start.js"
      }]
    } else {
      // not installed yet. select the install.js tab.
      return [{
        default: true,
        text: "Install",
        href: "install.js"
      }, {
        text: "Start",
        href: "start.js"
      }]
    }
  }
}

ENVIRONMENT

While it's possible to customize script behaviors by directly modifying the script files, this is not desirable.

We want a way to customize an app's behavior WITHOUT touching the code. We can achieve this through ENVIRONMENT.

Before

Let's say you want to write a script that automatically downloads an AI model to a specified directory (for example models). The script may look like this:

{
  "run": [{
    "method": "fs.download",
    "params": {
      "uri": "https://huggingface.co/stabilityai/stable-diffusion-xl-base-1.0/resolve/main/sd_xl_base_1.0.safetensors",
      "dir": "app/models/Stable-diffusion"
    }
  }]
}

The problem is, to change the behavior of this script, the end user will need to edit the URI using a file editor.

What if you wanted to let the end user modify the uri?


After

If you want to write a script that can be easily customized by users, you may want to create a file named _Environment (Must be prefixed with _).

Here's an example _ENVIRONMENT file:

#####################################################################################################################
#
# SD_INSTALL_CHECKPOINT
# - Delete this field if you don't want to auto-download a checkpoint when installing
# - Replace the URL with another checkpoint link if you want a different checkpoint
#
#####################################################################################################################
SD_INSTALL_CHECKPOINT=https://huggingface.co/stabilityai/stable-diffusion-xl-base-1.0/resolve/main/sd_xl_base_1.0.safetensors

Put this file inside the root of the script, along with pinokio.js and download.json, like this:

pinokio.js
download.json
_ENVIRONMENT

Then we can modify the download.json file like this:

{
  "run": [{
    "method": "fs.download",
    "params": {
      "uri": "{{env.SD_INSTALL_CHECKPOINT}}",
      "dir": "app/models/Stable-diffusion"
    }
  }]
}

Custom Install Screen

When you publish this repository, when the user installs the script, they will be shown the following custom install screen:

custom_install.png

With a user-friendly interface, the user can customize which URL to use when first installing the app.


Configure Menu

Also, after the install is complete, they will be able to access the same ENVIRONMENT editor under the Configure menu:

configure.png


How it works

The _ENVIRONMENT file you included is a template file. When a user downloads this script repository, here's what happens:

  1. A new ENVIRONMENT file (note that there is no _ prefix) is created by inheriting from the _ENVIRONMENT template file.
  2. From this point on, _ENVIRONMENT is NOT used.
  3. The ENVIRONMENT file is used to store the app's configuration going forward.
  4. The user can edit the configuration by either DIRECTLY editing the ENVIRONMENT file, or by editing through the built-in Configure menu.

Isolated Environment for Each App

These environment variables are not some special purpose things JUST for Pinokio. They are internally powered by the widely adopted Environment variable system.

This means we can use the ENVIRONMENT file to not only customize the script behavior but also ANYTHING that happens inside the app. When would this be useful?

Often, apps have their own ways of configuring. For example, all Gradio based apps let you customize the app's behavior through environment variables. Traditionally, running these apps in a customized manner involved either:

  1. Changing the environment variables GLOBALLY.
  2. or running environment shell commands like export GRADIO_SERVER_PORT=8080

Neither are ideal.

Fortunately, Pinokio's ENVIRONMENT file takes care of this automatically.

Let's say we want to let users customize GRADIO_SERVER_PORT and GRADIO_TEMP_DIR. All you need to do to enable this is set those values in the _ENVIRONMENT file (or ENVIRONMENT file if the user is trying to customize this on their end):

GRADIO_SERVER_PORT=8080
GRADIO_TEMP_DIR=./cache/GRADIO

These variables will be immediately available for editing in the Configure menu, and whenever run any script from the repository, these custom environment variables will be automatically applied.
