JSCL


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, 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. To use in Node,
node jscl-node.js; to use in Deno,
deno --allow-env --allow-read jscl-deno.js.

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
and go

- Static and dynamic non local exit catch,
throw;
block,
return-from.

- 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

- The format function

- Others

The compiler is very verbose, some simple optimizations or
minification could help to deal with it.

Feel free to hack it yourself
