Git Tools
Inspect and author Git interchange formats locally in the browser.
Git Tools is a standalone local-first application in the add·ideas Toolbox. Inputs are processed in the browser and are not uploaded.
Version 0.1 scope
- Unified and
git diffpatch parsing with file status, modes, renames, hunk counts, line numbers, statistics, binary markers, and diagnostics - Unified patch authoring from before/after text with bounded LCS, context selection, path safety, and missing-final-newline markers
- Root
.gitignorematching for comments, escapes, globstars, character classes, directory rules, negation, ordered explanations, and ignored-parent diagnostics - Strict SemVer 2.0 precedence plus common exact, comparator, partial, wildcard, hyphen, tilde, caret, AND, and OR ranges
- Conventional Commit builder and structural lint with breaking-change/footer diagnostics
- Keep-a-Changelog heading/section normalization, stable ordering, and duplicate-entry removal
Patch and before/after inputs are capped at 4 MiB with additional file, line, hunk, and diff-matrix bounds. .gitignore evaluates one repository-root file only; it does not read nested ignore files, global excludes, index state, or submodules. No workspace or .git directory is accessed. See docs/ARCHITECTURE.md and docs/PRIVACY-SECURITY.md.
