Franz Lisp: A Classic Lisp Implementation from UC Berkeley
What Is Franz Lisp?
Franz Lisp was a Lisp implementation developed at University of California, Berkeley by students of Richard Fateman. It was developed for porting Macsyma algebra system, an enormous Lisp application written in Maclisp, to DEC VAX-11 minicomputer. UC Berkeley distributed it with the Berkeley Software Distribution. Franz Inc. was founded to provide commercial support of Franz Lisp, but the company switched to Common Lisp afterward.
The original code is retrived from Franz Lisp Opus 38.93b at the CMU AI Repository. According to the page, that is placed in the public domain. However, since the origin of the code is the Berkeley Software Distribution, it would be safer to treat it as distributed under the term of the 4-clause BSD License. Thus, I decided to do so. Kamil Rytarowski pointed it out, thanks a lot!
Note that UCB have declared that the clause 3 is no longer effective for their code in BSD, so Franz Lisp in this repository is essentially under the term of the 3-clause BSD License that is OSI-approved and GPL-compatible.
See ftp://ftp.cs.berkeley.edu/pub/4bsd/README.Impt.License.Change for details.
Also, this repository contains no code from AT&T.
A Short Guide
franz/ directory contains the source code of the interpreter called
lisp. It is mostly written in C but plain old (pre-ANSI) one. There are also
some assembly code for VAX, Motorola 68000, etc.
lisplib/ directory contains Lisp code that may or may not run on Franz
Lisp, from official basic libraries to some foreign libraries such as a port
of Flavors (an object-oriented Lisp system) and the
loop macro. You must have
fun here! :)
liszt/ directory contains the source code of the compiler called
It is written in Franz Lisp itself. The names of franz and liszt are taken from
the Hungarian composer Franz Liszt.
pearl/ directory contains an implementation of PEARL (Package for
Efficient Access to Representations in Lisp) AI programming language that was
developed by Michael Deering and Joseph Faletti at the Berkeley AI Research
Project (BAIR). Some information is available at the Michael Deering's Web
page about PEARL.
utils/ directory contains some utilities used by the original developers.
