# Godiff
A native, minimal, local diff viewer for reviewing Git changes and committing
them: a reimplementation of codiff in Go
with MyGo's native UI. No webview, no JavaScript:
the window is drawn by MyGo on the GPU, with the system's fonts, accent color,
dark mode, menus and vibrancy.
## Features
- **Review local changes**: staged, unstaged and untracked files against
 `HEAD`, in one scrolling surface of file cards with sticky headers.
- **Split and unified diffs** with syntax highlighting (codiff's Licht and
 Dunkel palettes), word-level change highlighting, and unchanged lines that
 expand 100 at a time or all at once. New and deleted files show in one
 column.
- **Viewed files**: marking a file viewed collapses it, and it opens again
 once it changes. Generated files (lockfiles, `*.min.js`,
 `linguist-generated`, …) and dependency folders start collapsed.
- **Review comments**: click a line, or press J / K to
 choose a hunk and Enter , then copy every comment as Markdown,
 with the diff around it, for an agent or a colleague.
- **Commit** the files you choose, with a subject and a summary, from the
 sidebar's Commit button. Other staged work stays staged.
- **History**: browse commits and review any of them, or compare the work
 tree with a branch.
- **Pull requests**, after pulls.review:
 list the open pull requests of the repository's GitHub remote
 ( ⌘3 ) and review any of them, open or not. Godiff fetches its
 commits into your clone, so it reads as local changes do: highlighted,
 expandable, with pictures. Its files group by kind (code, tests, docs,
 config, dependencies, generated), each group with how much of it you
 viewed; review threads show under their lines, to reply to and resolve;
 comments go out alone or into your review, which you submit as a comment,
 an approval or a request for changes. A banner says when new commits are
 pushed.
- **AI review**: a coding agent installed on your machine — Claude Code,
 Codex, OpenCode or Pi — reviews the changes, a pull request's or your
 own: it summarizes them, groups the files by intent, and notes the lines
 that deserve attention, marking what needs care. It runs read-only, with
 the agent's own sign-in, and its review is kept until you ask for
 another. Choose the agent and the model in the review's card, among
 those the agent lists, of any of its providers; by default OpenCode
 reviews with the model it starts with itself. The card lists the notes,
 and the file tree marks the files with some: click one, or press
 N and ⇧N , to go from note to note.
- **Find in diffs** ( ⌘F ), a **file filter** ( ⌘P ) and a
 **command bar** ( ⌘K ).
- Image previews of changed pictures, a file tree with change counts and
 status letters, and a banner when the work tree changes.
- Sidebar navigation selects files, directories, commits and pull requests
 on pointer press, showing the new selection as the sidebar takes focus.
 Directory disclosure and button actions activate on release.
