Latest commit

In some case, Integerspool, Floatspool and Numberspool were not correctly instanciated. Their lisp field was not updated.
There was also a memory leak in nconcn. The use of fullcopy to duplicate a list is now copyatom, which checks if the list is a not new one beforehand.

LispE: Lisp Elémentaire

Hello,

Welcome to Lisp Elémentaire, a version of Lisp that is ultra-minimal but contains all the basic instructions of the language. The code also comes with a small internal editor from another NAVER's project: TAMGU.

LispE has different goals:

  • To show how to easily implement a powerful and extensible Lisp interpreter in C++.
  • To provide a real Lisp language that will allow you to discover a really fascinating language ...
  • To provide a code that can be compiled on any Windows, Linux or Mac OS machine, without any fuss

I based a large part of this work on the following article: The Root of Lisp.

CHECK binaries

We have stashed here precompiled versions for Window and Mac OS (including M1)...

Modern Functional Properties

LispE provides also some interesting properties such as: Data Structures

Finally, LispE can also be used as a Shell: Shell

Come and discover LispE: the Lisp Elémentaire.

Play with it

We provide a fun little program to discover some of the most interesting aspects of LispE: minzork

Have a look and try it
