This repository contains code examples for a series of blog posts "Great Tiny Languages".

Here you may find micro-implementations of the most fundamental historical programming languages. Each implementation is in Python, code is deliberately terse to keep it under ~50 lines of code. Only Python standard library is used, and even that to a very humble extent (sys, sometimes re, rarely itertool etc).

I hope this project becomes a good starting point in implementing your own programming languages or learning about the history of programming.

• asm.py - Assembly - compiles Python-ish assembly into bytecode and executes it.
• basic.py - BASIC - a subset of TinyBASIC, but it comes with a proper BASIC line editor!
• lisp.py - Lisp 1.5 - a classic, by John McCarthy, enough to interpret itself (meta-circular interpreter)
• apl.py - a k/simple interpreter, by Arthur Whitney, toy dialect of K (array processing programming language), which is a variant of APL itself.
• mouse.py - concatenative programming language MOUSE, as published in BYTE magazine from 1979.
• pl0.py - a PL/0 interpreter, by Niclaus Wirth.
• tcl.py - a tiny, tiny command language interpreter (TCL).
