* 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 [[http://davazp.net/jscl/jscl.html][here]]. But if you want to hack JSCL, you will have
to download the repository

=git clone git@github.com:davazp/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 tranfers ([[http://www.lispworks.com/documentation/HyperSpec/Body/s_tagbod.htm][tagbody]] and [[http://www.lispworks.com/documentation/HyperSpec/Body/s_go.htm][go]])
  - Static and dynamic non local exit ([[http://www.lispworks.com/documentation/HyperSpec/Body/s_catch.htm][catch]], [[http://www.lispworks.com/documentation/HyperSpec/Body/s_throw.htm][throw]]; [[http://www.lispworks.com/documentation/HyperSpec/Body/s_block.htm][block]], [[http://www.lispworks.com/documentation/HyperSpec/Body/s_ret_fr.htm][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 compiler is very verbose, some simple optimizations or
/minification/ could help to deal with it.

Most of the above features are incomplete. It is not so bad because
so the compiler is not too heavy, but it would be great if we were
just enough compliant to include a [[http://www.cs.cmu.edu/afs/cs/project/ai-repository/ai/lang/lisp/code/iter/loop/mit/0.html][loop implementation]], a format
implementation, or even [[http://www.cs.cmu.edu/afs/cs/project/ai-repository/ai/lang/lisp/oop/0.html][CLOS]] or non-CLOS OOP.
