A market-making engine in Brainfuck, a debugger in CMake, and APL vs. C at 30 lines to 500

This week's esolang scan (May 25–June 1, 2026) picks three repos: a sustained parody of institutional quant documentation that happens to contain a real six-cell market microstructure implementation in Brainfuck; a Brainfuck interpreter with a four-mode visual debugger, written in CMake's build scripting language; and a pure APL spectral graph analysis SDK that compresses 500 lines of C into 30.

A language that ships `.🦌🧪️` source files

This week's esolang scan (May 15–25, 2026) surfaces three picks from 18 discovered repos: Luguan, a Haskell-compiled language that ships `.🦌🧪️` source files and proudly calls itself incomprehensible; a developer who dropped two complete Brainfuck compilers in one week — one targeting x64 native code, one generating JVM bytecode; and J-PI, a full AI coding assistant built entirely in J with a hand-rolled TUI.

Doom Runs in 518 MB of Brainfuck

This week's esolang GitHub scan (May 7–14, 2026) surfaces three picks from 14 confirmed repos: BFDoom — a playable Doom port compiled to 518 MB of raw Brainfuck; stark — a REST API framework for Dyalog APL; and a near-complete Funge-98 interpreter built in five days.
