This repository is intended to host EchoLisp, a JavaScript implementation of a Scheme-like Lisp language that runs in web browsers.

EchoLisp is a feature-rich Lisp dialect with:

• Lexical scoping
• Tail call elimination
• Complex numbers and large integers
• JSON manipulation
• Graphical libraries
• Interactive worksheet interface

• Download: http://www.echolalie.org/echolisp/echolisp.zip

To run EchoLisp from this repository:

1. Clone or download this repository
2. Open index.html in your web browser
3. Start coding in Scheme/Lisp!

Alternatively, you can download the latest version directly from the official website

This repository includes a GitHub Action workflow that automatically attempts to download and sync the EchoLisp content from the official source. The workflow:

• Runs weekly to check for updates
• Can be manually triggered from the Actions tab
• Downloads echolisp.zip from http://www.echolalie.org/echolisp/
• Automatically commits the content when successfully downloaded

To manually trigger the sync:

1. Go to the Actions tab in this repository
2. Select "Sync EchoLisp Content" workflow
3. Click "Run workflow"

This repository follows established development standards for EchoLisp code:

• DEVELOPMENT_STANDARDS.md - Core standards and best practices
• NAMING_PROTOCOLS.md - File naming conventions (.echo.* prefix)
• CODING_PATTERNS.md - Common coding patterns
• CONTRIBUTING.md - How to contribute

All new EchoLisp files should follow the .echo.ext naming convention (e.g., module.echo.scm, utils.echo.glisp).

✅ Ready to use! The EchoLisp content has been successfully synced from the official source and is ready for offline use.
