Just my type: things I learned from writing my own programming language
summary
A first‑hand account of actually building a toy language: WholesomeLang implemented as WholesomeLang in Ruby, with a custom tokenizer and parser, a runner that accepts flags, lots of debugging views, and quirky primitives like type (prints) and “friends” for classes. Transcript shows gotchas—assumes spaces around =, assumes final newline—so portability breaks, it’s not packaged, and it forbids certain words across languages (prevents unwholesome words). Watch if concrete implementation details and tradeoffs matter.
