# chord-progression-parser A converter from chord progression strings to AST built in Rust that outputs wasm, so it can be used from JavaScript too. > NOTE: This library releases multiple packages. ![GitHub release (latest SemVer)](https://img.shields.io/github/v/release/lainNao/chord-progression-parser) > > - Rust: > - JS/TS(bundler): > - JS/TS(server): > - JS(CDN): ## Example You can try it on [CodeSandbox](https://codesandbox.io/p/devbox/vite-react-ts-forked-phmkrs?file=%2Fsrc%2FApp.tsx) ![example gif](https://i.imgur.com/kGwySIJ.gif) ## Documents - English - [about chord progression syntax](./_docs/en/about-chord-progression-syntax.md) - [how to develop](./_docs/en/how-to-develop.md) - [memo](./_docs/en/memo.md) - Japanese - [コード進行ASTの文法の説明](./_docs/ja/about-chord-progression-syntax.md) - [開発についての説明](./_docs/ja/how-to-develop.md) - [メモ](./_docs/ja/memo.md) ## How to use ### `Rust` - Install ```sh cargo add chord-progression-parser ``` - And use ```rust use chord_progression_parser::parse_chord_progression_string; fn main() { let input: &str = " @section=Intro [key=E]E - C#m(7) - Bm(7) - C#(7) F#m(7) - Am(7) - F#(7) - B @section=Verse E - C#m(7) - Bm(7) - C#(7) F#m(7) - Am(7) - F#(7) - B "; let result = parse_chord_progression_string(input); println!("{:#?}", result); } ``` ### `JavaScript/TypeScript (using bundler, like Vite, or If you are using Next.js)` - Install (example, use with `Vite`) ```sh npm install @lainnao/chord-progression-parser-bundler npm install -D vite-plugin-wasm ``` - Edit `vite.config.js` ```js import { defineConfig } from "vite"; import wasm from "vite-plugin-wasm"; export default defineConfig({ plugins: [wasm()], }); ``` - And use ```typescript import { parseChordProgressionString } from "@lainnao/chord-progression-parser-bundler/chord_progression_parser"; const result = parseChordProgressionString("C"); console.log(result); ``` ### `JavaScript/TypeScript (server like Node.js, Bun)` - Install ```sh npm install @lainnao/chord-progression-parser-node ``` - And use ```typescript import { parseChordProgressionString } from "@lainnao/chord-progression-parser-node/chord_progression_parser"; const result = parseChordProgressionString("C"); console.log(result); ``` ### `JavaScript(CDN)` - `index.html` ```html Document
