When Toy Languages Grow Up
summary
A small scripting language called Ink is implemented in Go, started 2019 and grown to tens of thousands of lines powering personal tools and dashboards touched daily by thousands; it uses a tree‑walk interpreter with a tokenizer → parser → evaluator pipeline, supports match expressions with a wildcard underscore, proper tail calls, and an isolate flag for granular OS permissions; it compiles some parts to JavaScript to run in browsers, ships an autoformatter written in Ink, and has produced a path tracer, a Twitter client, and a markdown web app despite being slower than Python.
