Implementations

impl GitVcs

pub fn open(root: &Path) -> Result<Self, VcsError>

pub fn open_with_context( root: &Path, context_lines: u32, ) -> Result<Self, VcsError>

Open with a custom number of context lines around diff hunks.

Trait Implementations

impl Vcs for GitVcs

fn git_dir(&self) -> Result<PathBuf, VcsError>

Resolved repository metadata directory. In a plain repo this is <root>/.git; in a linked worktree <root>/.git is a gitlink file and this resolves to the external gitdir it points at.

fn head(&self) -> Result<HeadInfo, VcsError>

Current branch, commit, and upstream.

fn status(&self) -> Result<StatusModel, VcsError>

Untracked / unstaged / staged sections as separate diff models.

fn working_tree_diff(&self) -> Result<DiffModel, VcsError>

HEAD vs workdir+index including untracked files: the review view.

fn commit_diff(&self, oid: &str) -> Result<DiffModel, VcsError>

Changes a single commit introduced over its first parent.

fn range_diff( &self, oldest_oid: &str, newest_oid: &str, ) -> Result<DiffModel, VcsError>

Combined diff of a contiguous commit range, from the first parent of oldest to newest (git diff <oldest>^..<newest> semantics). When oldest is a root commit its first-parent tree is the empty tree, so the range includes everything oldest introduced.

fn log(&self, limit: usize) -> Result<Vec<LogEntry>, VcsError>

History from HEAD, newest first.

fn branches(&self) -> Result<Vec<BranchInfo>, VcsError>

Local branches.

fn stage(&self, rel: &Path) -> Result<(), VcsError>

Stage a whole file (worktree deletions become staged deletions).

fn stage_hunk(&self, rel: &Path, hunk: &HunkId) -> Result<(), VcsError>

Stage one hunk out of the unstaged (or untracked) changes of a file.

fn unstage(&self, rel: &Path) -> Result<(), VcsError>

Reset a file’s index entry back to HEAD, keeping the worktree.

fn unstage_hunk(&self, rel: &Path, hunk: &HunkId) -> Result<(), VcsError>

Remove one staged hunk from the index, keeping the worktree.

fn discard(&self, rel: &Path) -> Result<(), VcsError>

Throw away worktree changes only; an untracked file is deleted. Refused while the file has staged changes (unstage first).

fn commit(&self, message: &str) -> Result<String, VcsError>

Commit the index; returns the new commit id.

fn head_message(&self) -> Result<String, VcsError>

Full message of the HEAD commit, for amend/reword editor templates.

fn amend( &self, message: Option<&str>, use_index: bool, ) -> Result<String, VcsError>

Amend HEAD, returning the new commit id. message None reuses HEAD’s message (extend); Some rewords it. use_index true folds the staged index into the new tree (extend/amend); false keeps HEAD’s tree (a pure reword). Local-only — no network.

fn create_branch(&self, name: &str, checkout: bool) -> Result<(), VcsError>

fn delete_branch(&self, name: &str) -> Result<(), VcsError>

Refused for the currently checked-out branch.

fn checkout(&self, name: &str) -> Result<(), VcsError>

fn stash_push(&self, message: Option<&str>) -> Result<(), VcsError>

Stash tracked changes (staged + unstaged), reverting the worktree to HEAD; untracked files are left in place, matching git stash. message None lets the backend label it. Local-only — no network.

fn stash_pop(&self) -> Result<(), VcsError>

Restore the most recent stash and drop it. Refused when there is no stash or the pop would conflict.

fn network_argv(&self, op: NetworkOp) -> Vec<String>

Argv to run for a network op, e.g. ["git", "push"]. The binary runs this in Vcs::workdir so the backend’s own CLI handles credentials; diffler never touches them. A future jj backend returns ["jj", …].

fn workdir(&self) -> Result<PathBuf, VcsError>

Working directory to run Vcs::network_argv in.

fn remote_url(&self, name: &str) -> Result<Option<String>, VcsError>

URL of the named remote (e.g. origin), if it exists. Used to detect the CI provider’s host without shelling out.

fn remotes(&self) -> Result<Vec<String>, VcsError>

Names of every configured remote, for multi-remote CI detection.
