Features
- TUI editor with a tool-section outline, file browser, live word/modal-state inspector, find & replace with preview, bookmarks, snippets and a command palette.
- Safe by default — every transform prints a diff and writes nothing unless you
pass
-i/-o. Writes are atomic;--backupkeeps a.bak. - Exact arithmetic —
Decimalthroughout; untouched lines round-trip byte for byte. - Transforms — renumber, strip, case, shift, scale, mirror, rotate, address math, feed/speed scaling, limited to a line, block or tool range.
- Analysis — stats, tool list, 21 validation rules, NC-aware diff.
- Machine profiles for Fanuc (mill/turn), Haas, Siemens ISO and generic ISO, plus your own TOML profiles.
- CI-friendly — versioned
--jsonoutput and meaningful exit codes.
