? What is this repo? This repo contains the code for Particle Syntax and the Parsers Programming Language. These are the core layers upon which Scroll is built.
? Who is this for? This repo is for advanced Scroll developers.
? How do I build Parsers? You can try the Parsers tutorial. link parsersTutorial.html Parsers tutorial
This ScrollSDK contains two implementations of Parsers: one in TypeScript and one in Parsers.
You write Parsers to extend Scroll. By creating Parsers with the SDK you get a parser, a type checker, syntax highlighting, autocomplete, a compiler, and virtual machine for executing your version of Scroll. The ScrollSDK also includes a simple web IDE for writing Parsers called Parser Designer. link designer/index.html Parser Designer
At this point in time, to make your Parsers do very useful things, you also need to use another language that you know. The ScrollSDK lets you create new languages using just Scroll or Scroll + Javascript. Parsers can include code from any programming language, not just Javascript. Though at the moment only Scroll + Javascript is supported.
The ScrollSDK currently includes a number of libraries and apps to use (scripts in the "products" folder).
code const {Particle} = require("scrollsdk/products/Particle.js") const particle = new Particle("hello world") console.log(particle.asString)
code
code npm install . npm run local open http://localhost:3333/
code npm install . npm run local open http://localhost:3333/designer
If you look at the source, you will also see a set of build tools (such as Builder and TypeScriptRewriter). These are currently undocumented and not recommended for external use.
code npm run build npm test
The ScrollSDK is a monorepo. With on average over 1 major version released each month for the past 2.5 years, it would take a lot of overhead to constantly be updating 10+ different repositories and modules every month. Once we're more confident in the theory and best practices, it might make sense to break this repo into independent modules. That being said, we despise unnecessary dependencies as much as anyone. If anyone wants to create some automated submodules built from the projects in this monorepo, to allow for consuming of a smaller subset of the code and dependencies in this module, feel free to do so.

All breaking changes are mentioned in the releaseNotes. We follow semantic versioning, so breaking changes should not happen if you stay on the same major version. link releaseNotes.html releaseNotes
If you build a Particles library/SDK in another language, let us know and we'll add a link.
If you are working on a Particles library in a new host language, feel free to post an issue or ask for help in the WWS subreddit. https://www.reddit.com/r/WorldWideScroll WWS subreddit

Particles was originally called Tree Notation. Parsers was originally called Grammar.
This is the first Particles and Parsers libraries in existence, so there were no alternative implementations. Note and Space were predecessors to Particles. If a better alternative low level syntax to Particles is possible, it has yet to be discovered.
All that said, the important part of this repo is not the code but the design patterns. Particles is very simple, and you can implement the patterns contained here in your own code without using this library. In fact, that is often the best way to use Particles!
It is helpful to set "goto_anything_exclude_gitignore": true to ignore files in gitignore. Read more here.
