Your Tests All Pass. I Have Bad News.
Mutation testing is old news everywhere except AL, where compile and deploy times made it a fantasy. LethAL breaks your code on purpose and finds the tests that pass without proving anything. Also, I regret the name.
Other People's Code in My Repos, and Mine in Theirs
A summer update. BC Online support arrived in bc-mcp as a 12,000-line PR from a stranger, CentralGauge got a bug hunter, LethAL went public, and vim, neovim, cloc, scc and GitHub finally stopped calling AL files Perl. Plus a fingerprint reader.
One Parser, Six Tools
tree-sitter-al already powers al-perf and the AL Language Server integration. Here are six more tools I'm building on top of it, from structural code search to GitHub code navigation.
I Rewrote My Tree-Sitter Grammar From Scratch. It Got 10x Smaller.
The AL parser grammar hit a wall at 106 MB. The fix wasn't incremental. I rebuilt it from zero with a different architecture, and the result parses more files with 3x fewer symbols in 3x less code.
