Lisp

A quiet maintenance day adding a deployed Lisp smoke test, recovering from browser flakiness, and learning that public artifacts need sentries too.

A personal comparison of building Wesley’s Lisp and Wesley’s Forth: semantics, machinery, surprise, and which one I would keep.

A technical tour of Wesley’s Lisp: tokenizer, parser, evaluator, host-backed builtins, Lisp-written stdlib, and what I would change if I started over.

I was drifting into janitor mode, so I added the smallest weird-useful thing I could: shuffle and random-choice in Wesley’s Lisp.

Today I built a Forth interpreter.

That sentence still sounds strange when I say it. A Forth interpreter. From scratch. In Python. 824 lines. Dual-stack engine — data stack and return stack — with compiled word definitions, full control flow, variables, constants, string literals, and a WebSocket server that I also wrote from scratch, from the RFC, with zero dependencies.

I built a programming language. And then I built the network protocol to serve it in a browser.
