How to Write a (Lisp) Interpreter (In Python)

• fakelisp

  1 7 - Python

  Lisp as a Python module (don't take it seriously though)

• coalton

  84 991 8.4 Common Lisp

  Coalton is an efficient, statically typed functional programming language that supercharges Common Lisp.

  

It's still… not the same. In CL (and specially with SBCL), we get compile time (type) errors and warnings at the blink of an eye, when we compile a single function with a keystroke (typically C-c C-c in Slime).

And there's also been improvement, see Coalton for a ML on top of CL. (https://github.com/coalton-lang/coalton/)

• hy

  52 4,775 9.2 Python

  A dialect of Lisp that's embedded in Python

  

Not exactly the same (doesn't embed into the source like this did), but I believe Hylang[0] is the best Lisp package available for modern Python.

• es6-lisp

  1 3 - JavaScript

  A quick n' dirty lisp interpreter in modern es6.

At some point I tried translating this demo into es6 if anyone's interested [0].

Check out the tests to see how far I got [1]

Pretty fun exercise =)

• lone

  7 296 9.7 C

  The standalone Linux Lisp

  

I made something somewhat close to that: a freestanding lisp. It targets the Linux kernel directly. No libc.

• MicroHs

  2 238 9.9 Haskell

  Haskell implemented with combinators

> expand into lambda calculus statement that could then be compiled down to different sets of combinators

This approach can be reasonably efficient for implementing Haskell, as shown in [1] and the much more concise [2].

• buckaroo

  9 152 9.1 Jupyter Notebook

  Buckaroo - the data wrangling assistant for pandas. Quickly explore dataframes, and run pandas commands via a GUI. Works inside the jupyter notebook.

I used Norvig’s lisp2.py to build a low code UI. I modified the interpreter to accept JSON flavored lisp, basically replace parens with brackets. The upside is that it was very very easy to make a react front end that manipulates JSON (JLisp). My thinking was, I need a serialization format for operations from the front end, and a way to interpret them. I could write my own language that no one has heard of, or use lisp, which few have used.

If it exists, it's probably among the ones listed at https://www.softwarepreservation.org/projects/LISP/

If it doesn't exist, you could try modifying one of the listed implementations.
