What it is AI-extracted, prompt v1, taxonomy v1, 2026-08-30, confidence not recorded
A curated collection of links to single-file implementations of programming languages such as Lisp, Forth, Pascal, BASIC, and Brainfuck. It serves as an approachable educational resource for learning how programming languages and interpreters are built.
Use cases
- learn how to implement a programming language
- find a minimal lisp interpreter source code
- study a small forth implementation in C
- understand interpreters without reading millions of lines
- find teaching examples for a compilers course
- explore how brainfuck or basic interpreters work
When to choose
- you want concise, readable examples of language implementations
- you are learning interpreter or compiler fundamentals
- you need small self-contained codebases to study or teach with
When to avoid
- you need a production-ready language implementation
- you require complete, efficient, or well-supported toolchains
- you need a project with an explicit license or active maintenance guarantees
