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.
To clone the repository, run this command:
git clone https://git.savannah.nongnu.org/git/alisp.git
You can find the released tarballs down on this page, but I recommend running from the latest commit, since new features and bugfixes happen often.
To get the gist of this project, see README (https://git.savannah.nongnu.org/cgit/alisp.git/tree/README) and NOTES (https://git.savannah.nongnu.org/cgit/alisp.git/tree/NOTES).
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 includes more than three quarters of Common Lisp! Run the test.pl script (https://git.savannah.nongnu.org/cgit/alisp.git/tree/test.pl) for a tour de force of the interpreter.
alisp is quite friendly to the programmer: it features a basic profiler and also a debugger with stepping, a feature that most free CL implementations lack.
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.

Version 1.1 is out!
Now al has improvements in LOOP, a better function compiler and a limited file compiler, better support for pathnames and for querying the filesystem, various improvements to the profiler and the stepper, initial support for watchpoints and tons of bugfixes as usual. [...]

Version 1.0 is out!
Now al has a basic pretty printer, better LOOP, handling of compiler macros, much better CLOS, better inspection tools including a backtrace printer, more complete handling of pathnames, a better minimal compiler, more reader macros, support for symbol macros, a much better debugging and stepping experience. As usual, tons [...]

Version 0.999 is out.
Now al has more sharp macros and many improvements in all kinds of arrays, filenames, fill pointers, minimal compilation, generic functions, streams, LOOP, FORMAT; it also has ROOM, TRACE and stepping in the debugger, that almost no free CL implementation has; last but not least, tons of bug fixes and closed leaks make al [...]

Version 0.99 is out.
Now al has better support for UTF-8, fill pointers, macro functions, generic functions, standard objects, pathnames and file operations, restarts; we also have minimal compilation and a basic debugger and profiler; finally a lot of bug fixes and closed leaks.
