How can we improve the workflow for `pipeline.toml` and `ambient.toml`?

[chaosprint]

So far syntax like:

[[pipelines]]
type = "Models"

is hard to write.

Perhaps it's better to make an interactive CLI tool like this:

ambient assets new

What kind of pipeline do you wish to add? Select with space.
- [x] model
- [ ] audio
- [ ] images

Please input your asset URL:
(you can drag and drop to your terminal to get the URL)
(if the file not in the project/assets folder, the file will be copied there)

This may also apply to new components with CLI tools like ambient component new:

My top pain points:

• [ ] when I mistype F32 to f32, the error info is not very easy to read
• [ ] the error for messages is hard to understand and debug

[FredrikNoren]

We used to have a ui for the pipelines before, and it's quite easy to add again. Here's what needs to be done:

1. Add an ambient edit-pipelines command
2. Add ElementEditor to all the type in pipeline_types (see auto_editor example
3. In that mode, don't render the normal client, but instead render all the pipelines using the automatic editors

There's some nuance here too; we need to re-implement an editor for AssetUrls, (probably a file picker), and this UI would need to support showing a file list for the assets so you can create pipelines in different directories. So it's a bit of work to get it all working.

[ten3roberts]

Do you feel that the errors have regressed a lot since before adding the "improved error reporting"

What is the error for when you mistype?

There is some limitations in the serde toml parser due to maturity where errors don't have the same amount of context or line information as other formats, but after #444 these errors should be more descriptive than the previous data did not match any variant of PipelinesOneOrMany.

[chaosprint]

yes, it's better.

The errors I mentioned are some legacy issues I encountered with ambient.toml before:

For example, if we mistype the component type I32 to i32, we get:

 ~/Dev/afpsmod  ambient run                                                                                                                         101 ✘  at 04:22:01 PM

note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace

If the type typo is inside the messages, that will become a really prolonged and confusing one:

The error situation is better in #417 (the types are resolved by the semantic system, so it can better report on errors). For manipulation of the actual embers and pipelines, I agree that it would be nice to have a more systematic approach to it.

The two proposals we've discussed internally are 1) CLI tooling, similar to what's described in this issue 2) an enhanced debugger/editor that lets you visually configure the project and pipelines

We'll see what we can do.

[chaosprint]

Before this is decided, I think it's better to add an empty pipeline.toml in the ./assets/ folder at the start template, with comments/docs inside, like this:

# -------------------------------
# Uncomment any "pipeline" that can suit your need
# This will create a pipeline for everything inside this folder FBX, GLB
# -------------------------------
# [[pipelines]]
# type = "Models"

# -------------------------------
# You can have multiple pipelines
# This is useful for processing things differently
# For example, you may want to use build-in colliders for some models only
# -------------------------------

# [[pipelines]]
# type = "Models"
# sources = ["maps/**/*"]

# [pipelines.collider]
# type = "FromModel"

# [[pipelines]]
# type = "Models"
# sources = ["animations/**/*"]

# -------------------------------
# Create another pipeline for audio
# convertion is false by default and optional
# -------------------------------

# [[pipelines]]
# type = "Audio"
# convert = true
# sources = ["sound/**/*"]

# -------------------------------
# This is for importing an material such as image
# Then in the Rust code, you can import the material like this
# You may need to use other numbers (not just 0) if you have multiple material to import
# ```rust
# .with(pbr_material_from_url(), asset::url("assets/pipeline.toml/0/mat.json").unwrap())
# ```
# -------------------------------

# [[pipelines]]
# type = "Materials"
# output_decals = false

# [pipelines.importer]
# type = "Single"
# name = "pic1"
# base_color = "pic1.jpeg"

@philpax how do you think? I think we need this "traffic sign". Otherwise, users will get confused, have to break the dev flow and try to find examples or docs.

[philpax]

That seems pretty reasonable - tooling would be nice, but it seems unlikely we'll be able to get that any time soon. Feel free to PR that up and I'll do clean-up and merge it in 👌
