A small lisp written in Python

branch: master
README.rst

Pylisp, a lisp for pythonistas

A small lisp written in Python. The goals are not to implement any specific lisp dialect. That said, aims are to be as Scheme-like as possible, except with Common-Lisp style macros, and without (so far) continuations. The largest overarching goal, however, is to be as compatible as possible with Python.

Usage

One can call up a pylisp interpreter simply by running the command pylisp, and files can be passed as arguments, which will be run.

One can also use import pylisp in a standard python program. This will enable the importation of lisp files as python modules. For example, one could create a file called module.lsp:

(def testfunc (x y)
  (+ x y 7))

and a python file test.py:

import pylisp
import module

assert module.testfunc(7, 4) == 18

Language Features

More can be found in the docs subdirectory, but in short, pylisp includes almost-common-lisp-style conditions/handlers, standard common-lisp-style macros, functions and objects built off of the Python model, and a package/module system identical to Python's.

Something went wrong with that request. Please try again.
