The test hardcoded 'refs/heads/main' for update-ref, but without
init.defaultBranch config (as in nix sandbox), git defaults to 'master'.
This caused the signed commit to be on a different branch than HEAD,
so arc log showed the unsigned commit instead.
Use 'git symbolic-ref HEAD' to get the actual branch name.
Also fix missing blank line separator between header and body.
Detect GPG vs SSH signatures when displaying commits. GPG-signed
commits from cloned/migrated git repos now show as valid with the
issuer key ID instead of failing SSH signature verification.
- Extract git commit signatures (gpgsig) during clone, migrate, and pull
- Sign git commits on push/sync when a signing key is configured
- Add tests for signature preservation and signed push
The imported counter was incrementing once per ref processed, not once
per commit converted. Since git_to_arc recursively walks the entire
ancestor chain, a single ref import would convert all reachable commits
but only count as 1.
Fix by measuring the growth of the git-to-arc map before and after the
import loop. Also strengthen tests to assert exact counts for commits,
bookmarks, and tags.
Add a centralized ui module with Arc's visual identity: colored commit
IDs (magenta), bookmarks (cyan), tags (yellow), status symbols, and
diff highlighting. Update all command output and tests accordingly.
- Add ssh-key crate dependency for SSHSIG format signing/verification
- Add signing module with sign, verify, and fingerprint functions
- Add ssh_signature field to Commit model (optional, backward-compatible)
- Integrate signing into commit flow (signs when user.key is configured)
- Show [signed] tag in log output for signed commits
- Show signature fingerprint and verification status in show output
- Gracefully degrade if key is missing/invalid (warns, commits unsigned)
- Add openssh to nix flake nativeCheckInputs for ssh-keygen in tests
- Add comprehensive signing tests covering signed/unsigned commits
- config set/get/show/unset commands with dotted key paths (user.name, default.bookmark, aliases.c, etc.)
- local config overrides global config per rule 21
- alias expansion at CLI level before dispatch per rule 23
- InvalidConfigKey error variant
- 28 tests covering all config operations, global/local resolution, and alias expansion
Add named stash support with create, use, push, pop, rm, and list
commands. Stashes are stored as YAML in .arc/stashes/named/ with a
stack-based push/pop model. Active stash tracked in state.yml.
- stash push saves dirty changes and resets worktree to clean state
- stash pop requires clean worktree and matching HEAD base commit
- 28 integration tests covering all commands and edge cases
- new error variants: StashAlreadyExists, StashNotFound, NoActiveStash,
NothingToStash, StashEmpty, StashBaseMismatch
- Add reset command to discard worktree changes (all or specific files)
- Add revert command to create inverse commits (preserving immutability)
- Add merge command with three-way merge and conflict detection
- Add graft command to cherry-pick commits onto bookmarks
- Create merge.rs with file-level and line-level three-way merge engine
- Create modify.rs orchestrating undo/modification operations
- Add MergeConflicts and NoMergeBase error variants
- Make refs utility functions (write_tree, clean_tracked_files) public
- Make inspect::myers_diff public for reuse in merge engine
- Add comprehensive tests for all four commands
- Add src/refs.rs with mark_add/rm/list/rename, tag_add/rm/list, switch
- Bookmarks stored as YAML RefTarget files in .arc/bookmarks/
- Tags stored as YAML RefTarget files in .arc/tags/ (immutable)
- Switch reconstructs worktree from delta chain, checks for dirty state
- Add error variants: BookmarkNotFound, BookmarkAlreadyExists, TagNotFound,
TagAlreadyExists, CannotRemoveActiveMark, DirtyWorktree
- Wire up CLI dispatch for mark, tag, and switch commands
- Fix cli.rs tests to run mark/tag list within a repo context
- Add 35 new tests across tests/mark.rs, tests/tag.rs, tests/switch.rs
- arc log: shows commit history newest-first with optional range support
- arc show: displays commit details by bookmark/tag/commit-id/prefix
- arc history: blame-style line attribution using Myers diff algorithm
- New resolve module for target resolution (bookmark → tag → commit prefix)
- New inspect module with timestamp formatting (no extra deps)
- Tests for all three commands (17 new tests, 82 total)
- Add commit command with auto-change detection (no staging area)
- Add status command showing added/modified/deleted files
- Add diff command with unified diff output
- Store commits as ZSTD-compressed MessagePack in .arc/commits/<id>.zst
- Generate commit/delta IDs via SHA-256 hashing
- Reconstruct committed state by replaying delta chains
- Add ignore pattern matching with glob support (.arcignore/.ignore)
- Always exclude .arc/ directory from worktree scanning
- Update HEAD and bookmark refs on commit
- Add NothingToCommit error variant
- Add zstd, sha2, hex dependencies
- Add 30 new tests across commit, status, diff, and tracking
