}

Per-repository state — one instance per open tab.

Fields

repo_path: Option<PathBuf>

Path to the currently opened repository (workdir root).

repo_info: Option<RepoInfo>

High-level information about the opened repository.

branches: Vec<BranchInfo>

All branches (local + remote) in the repository.

current_branch: Option<String>

Name of the currently checked-out branch.

commits: Vec<CommitInfo>

Commit log (newest first).

selected_commit: Option<usize>

Index into commits of the currently selected commit.

anchor_commit_index: Option<usize>

Anchor commit index for range selection — set on a plain click.

selected_commits: Vec<usize>

Ordered (ascending) list of commit indices in the current range selection.

graph_rows: Vec<GraphRow>

Per-commit graph layout rows for branch visualisation.

unstaged_changes: Vec<DiffFileEntry>

Unstaged (working-directory) changes.

staged_changes: Vec<DiffFileEntry>

Staged (index) changes.

commit_files: Vec<DiffFileEntry>

Lightweight file list for the currently selected commit (path + status only).

selected_commit_oid: Option<String>

OID of the currently selected commit (needed for on-demand file diff loading).

selected_file_index: Option<usize>

Index of the selected file in commit_files.

is_loading_file_diff: bool

True while a single-file diff is being loaded.

anchor_file_index: Option<usize>

Anchor index for range selection — set on a regular click, kept fixed while the user extends the selection with Shift+Click.

selected_commit_file_indices: Vec<usize>

Ordered list of file indices currently multi-selected in the commit file list (Shift+Click). Always stored in ascending index order (lowest index first).

multi_file_diffs: Vec<DiffInfo>

Diffs for all multi-selected files (populated when 2+ files are selected).

commit_range_diffs: Vec<DiffInfo>

Combined diff for all commits in the current range selection (populated when selected_commits.len() > 1). Shown in the diff panel instead of single-commit diff.

selected_diff: Option<DiffInfo>

The diff currently displayed in the diff viewer panel.

commit_message: String

Text in the commit-message input.

stashes: Vec<StashEntry>

All stash entries.

remotes: Vec<RemoteInfo>

Configured remotes.

show_commit_detail: bool

Whether the commit detail pane is visible.

new_branch_name: String

Text in the “new branch name” input.

show_branch_create: bool

Whether the inline branch-creation UI is visible.

local_branches_expanded: bool

Whether the Local branches section is expanded.

remote_branches_expanded: bool

Whether the Remote branches section is expanded.

stash_message: String

Text in the “stash message” input.

selected_unstaged: HashSet<String>

Set of selected unstaged file paths (for multi-select).

selected_staged: HashSet<String>

Set of selected staged file paths (for multi-select).

anchor_unstaged_index: Option<usize>

Anchor index for Shift+Click range selection in the unstaged list.

anchor_staged_index: Option<usize>

Anchor index for Shift+Click range selection in the staged list.

pending_discard: Option<String>

File path pending discard confirmation (None = no pending discard).

status_message: Option<String>

Transient status-bar message (e.g. “Branch created”).

error_message: Option<String>

Error message shown in a banner / toast.

is_loading: bool

True while an async operation is in flight.

context_menu_pos: (f32, f32)

Cursor position captured at the moment the context menu was opened. Used to anchor the menu so it doesn’t follow the mouse after appearing.

context_menu: Option<ContextMenu>

Currently open context menu, if any.

rename_branch_target: Option<String>

Name of the branch currently being renamed (None = not renaming).

rename_branch_input: String

The new name being typed in the rename input.

create_tag_target_oid: Option<String>

When Some(oid), the tag-creation inline form is visible, targeting that OID.

create_tag_annotated: bool

True when creating an annotated tag; false for a lightweight tag.

create_tag_name: String

The tag name the user is typing.

create_tag_message: String

The annotated tag message the user is typing (only used when create_tag_annotated is true).

create_branch_at_oid: Option<String>

When Some(oid), the inline “create branch at this commit” form is visible.

commit_scroll_offset: f32

Current scroll offset of the commit log in pixels. Tracked via on_scroll so virtual scrolling can render only the visible window of rows.

hovered_commit: Option<usize>

Index of the commit row currently being hovered by the mouse. Used to show ghost branch labels and highlight the row.

branch_context: Vec<Option<String>>

Pre-computed branch context labels for each commit row. For rows with refs, this is empty (the real badges are shown instead). For rows without refs, this contains the inherited branch name from the nearest ancestor in the same graph lane.

diff_scroll_offset: f32

Current scroll offset of the diff viewer in pixels.

commit_display: Vec<(String, String)>

Pre-computed display strings for each commit: (relative_time, truncated_author). Computed once when commits load to avoid per-frame string allocations. The summary is read directly from commits[i].summary to avoid duplication.

has_more_commits: bool

Whether there are potentially more commits to load beyond those already shown.

is_loading_more_commits: bool

Guard: true while a background load-more task is in flight (prevents duplicates).

file_history_path: Option<String>

When Some(path), the file-history overlay is shown for that repo-relative path.

file_history_commits: Vec<CommitInfo>

Commits loaded for the file-history overlay (newest first).

file_history_scroll: f32

Scroll offset of the file-history list in pixels.

blame_path: Option<String>

When Some(path), the blame overlay is shown for that repo-relative path.

blame_lines: Vec<BlameLine>

Blame lines loaded for the blame overlay.

blame_scroll: f32

Scroll offset of the blame view in pixels.

pending_delete_file: Option<String>

When Some(path), a delete-confirmation banner is shown for that file.

Implementations

impl RepoTab

pub fn new_empty() -> Self

Create an empty tab (no repo open — shows welcome screen).

pub fn has_repo(&self) -> bool

Whether a repository is currently open in this tab.

pub fn default_remote(&self) -> String

Name of the first remote, or “origin” as a fallback.

pub fn display_name(&self) -> String

Display name for the tab (last path component, or “New Tab”).

pub fn apply_payload(&mut self, payload: RepoPayload, path: PathBuf)

Apply a full repo payload to this tab, resetting transient UI state.

The currently selected commit (if any) is re-pinned by OID after the new commit list arrives, so background auto-refreshes (git-watcher or staging changes) never clear the user’s selection.
