Pyret

This repository holds the implementation of the Pyret programming language and its related tools.

Directories

Most directories map explicitly to logical components and deployed systems:

• lang/: compiler and standard libraries
• code.pyret.org/: server and client files for the code.pyret.org web service
• embed/: static HTML embedding package (https://www.npmjs.com/package/pyret-npm)
• npm/: CLI package (https://www.npmjs.com/package/pyret-embed)
• codemirror-mode/: CodeMirror 5 mode for Pyret highlighting and indentation
• pyret.org/: Pollen source of the pyret.org homepage
• vscode/: Visual Studio Code extension (https://marketplace.visualstudio.com/items?itemName=PyretProgrammingLanguage.pyret-parley, https://open-vsx.org/extension/PyretProgrammingLanguage/pyret-parley)

Individual directories are separate projects, and have their own READMEs, Makefiles, package dependencies, and so on. Some of them create or contain symlinks to others (e.g. code.pyret.org relies on a symlink to lang/).

There are also directories only related to testing:

• .github/: for automated testing workflows (testing only; deployment to servers and package registries is managed outside of this repository)
• browser-test/: shared infrastructure for headless testing across the browser and webview components (code.pyret.org, embed, vscode)

Historical Note

This monorepo was consolidated from several now-readonly repositories in 2026:

• code.pyret.org/ -> brownplt/code.pyret.org
• docs/ -> brownplt/pyret-docs
• codemirror-mode/ -> brownplt/pyret-codemirror-mode
• npm/ -> brownplt/pyret-npm
• pyret.org/ -> brownplt/pyret.org
• embed/ -> brownplt/pyret-embed
• vscode/ -> jpolitz/pyret-parley-vscode
• lang/ -> brownplt/pyret-lang (this repository), #horizon and #master branches. (This repository was kept at the same Github org/repo to maintain issues, PRs, and other historical references)
