A cute but powerful little LISP dialect geared towards generating images.
Inspired by Norvig's lis.py, Impl started as a subset of Scheme, but diverged because I had an idea to make a language that produces images from language features.
Impl has a good size set of standard procedures and keywords.
Impl supports:
- List, Int, Float, String, and Boolean operations borrowing from Python's semantics
- User-defined variables and first-class procedures with lexical scope
- If-else conditionals
- Ease of use language features like
let,for, and' quoting - "keywords" like
:x, inspired by Clojure - etc.
Examples can be found in _examples/, but here are a couple of animations I generated using Impl.
Linear Regression Fitting
python <path to impl.py> <source file name?>
Running Impl without any arguments results in the REPL, which can evaluate expressions but is not meant for generating images. Running Impl with one filename argument executes the given file.
