This group is not part of the GNU Project.

This is a lisp implementation.  Now it is just an interpreter, but I will add some compilation later.  I aim for Common Lisp conformance, but I'm not religious about it.

I write alisp in C89 syntax and standard library.

I use GNU readline (optionally) and GNU mp as external libraries, for line input and arbitrary precision arithmetic respectively.

The implementation is incomplete as of now.  See the test.pl script for a tour de force of the interpreter.

This is a solo project at the moment, so please don't send patches.  But do send bug reports and suggestions to the address you find in README!  If you need some lisp construct, tell me.

I release alisp as free software under GPL version 3 or later.

If you like this project, you can make a recurrent donation at https://liberapay.com/andreamonaco.  Thank you very much!

If you know of any relevant grant or have other funding suggestions, write to me.

Version 0.97 is out.

Now al has plists, bitwise operators, random functions, auxiliary variables, more math functions, restarts, basic support for classes and generic functions.  We can now say that al has limited support for each and every aspect of ANSI CL, and that half of the standard symbols are implemented.
