# JSCL 

[![Pipeline CI](https://github.com/jscl-project/jscl/actions/workflows/main.yml/badge.svg)](https://github.com/jscl-project/jscl/actions/workflows/main.yml)

JSCL is a Common Lisp to JavaScript compiler, which is bootstrapped

from Common Lisp and executed from the browser.



  

    

  



## Getting Started

You can try a demo online [here](https://jscl-project.github.io/), or

you can install the JSCL npm package:

    npm install -g jscl

    

to run `jscl-repl` in NodeJS.

## Build

If you want to hack JSCL, you will have to download the repository

    git clone https://github.com/jscl-project/jscl.git

*load* `jscl.lisp` in your Lisp, and call the bootstrap function to

compile the implementation itself:

    (jscl:bootstrap)

It will generate a `jscl.js` file in the top of the source tree. Now

you can open `jscl.html` in your browser and use it.

## Status

JSCL is and will be a subset of Common Lisp. Of course it is far from

complete, but it supports partially most common special operators,

functions and macros. In particular:

- Multiple values

- Explicit control transfers

  [tagbody](http://www.lispworks.com/documentation/HyperSpec/Body/s_tagbod.htm)

  and [go](http://www.lispworks.com/documentation/HyperSpec/Body/s_go.htm)

- Static and dynamic non local exit [catch](http://www.lispworks.com/documentation/HyperSpec/Body/s_catch.htm), 

  [throw](http://www.lispworks.com/documentation/HyperSpec/Body/s_throw.htm); 

  [block](http://www.lispworks.com/documentation/HyperSpec/Body/s_block.htm),

  [return-from](http://www.lispworks.com/documentation/HyperSpec/Body/s_ret_fr.htm).

- Lexical and special variables. However, declare expressions are

  missing, but you can *proclaim* special variables.

- Optional and keyword arguments

- SETF places

- Packages

- The `LOOP` macro

- CLOS

- Others

The compiler is very verbose, some simple optimizations or

*minification* could help to deal with it.

Most of the above features are incomplete. The major features that are still missing are:

- The `format` function

*Feel free to hack it yourself*
