Peppermint C89 port

This directory is a clean native C89 implementation of the language behavior present in the original TypeScript interpreter.

Original project: https://github.com/lainq/peppermint

Implemented subset:

• let name := expression bindings
• integer and floating-point literals
• quoted strings with basic escapes
• +, -, *, /, and %
• string concatenation with +
• # comments and line-oriented programs
• @argv and @argv:N
• @env:NAME and @exit

The original repository also contains a separate Brainfuck compiler/runtime; that is not silently folded into this first language-core port.

Build

Requires only a C compiler with C89 support:

make
./peppermint smoke.ppm hello

The build uses -std=c89 -pedantic and has no TypeScript, Node.js, Beef, or third-party runtime dependency.
