7.6. fix-lint-errors — Lint Auto-Fixer

fix-lint-errors rewrites source to resolve mechanical lint findings. It walks each input file’s AST, collects edits for the fixable rules, and writes them back — then compile-verifies the result and auto-reverts a file whose rewrite broke it.

Fixable rules: STYLE005 (if (c) { return } → if (c) return), STYLE017 (boolean return ladders), STYLE018 (b == true shapes), PERF013 (a += 1 → a++), PERF015/PERF016 (ternary min/max/abs), PERF017 (length(x) == 0 → empty(x)). Rules that need cross-statement restructuring are out of scope — fix those by hand from the lint report.

7.6.1. Quick start

daslang utils/fix-lint-errors/main.das -- <files...>

Flags: --dry-run (print edits, write nothing), -q (suppress per-file lines), --help for the rest.
