Add tree view mode for file lists

Summary

Adds a user-selectable FileListMode (Plain list or Tree) and applies it to file lists across the app, including the Create Pull Request screen. The mode is persisted locally and synced through the existing settings snapshot/cloud settings path.

What changed

Settings model and persistence

  • New FileListMode enum (list, tree) with titles, conforming to String, Codable, CaseIterable, Identifiable, Sendable in macgit/Models/AppSettingsSnapshot.swift.
  • AppSettingsSnapshot gains a fileListMode property (default .list), included in its initializer, Codable coding, and Equatable synthesis.
  • Decoding uses decodeIfPresent(...) ?? .list, so existing snapshots without the key remain compatible.
  • AppState adds a @Published var fileListMode backed by the "fileListMode" UserDefaults key, reads it on load (defaulting to .list), includes it in snapshot/currentSettingsSnapshot construction, and applies it in snapshot application (macgit/App/AppState.swift).
  • CloudSettingsDocument.encode writes fileListMode.rawValue; decoding reads it via optionalString with a .list default and validates against FileListMode(rawValue:) (macgit/Services/FirestoreSettingsStore.swift).

New views

  • macgit/Views/Common/FilePathListView.swift
  • macgit/Views/FileStatus/FileStatusTreeNativeList.swift
  • macgit/Views/History/CommitFileTreeNativeList.swift

Integration into existing views

  • FileStatusView and CommitFileListView updated to support list/tree rendering.
  • HistoryCommitDetailView, PullRequestDraftChangesView, and GeneralSettingsView updated (settings UI exposes the mode).
  • MainWindowView+PullRequestActions.swift updated.

Create Pull Request window

  • CreatePullRequestWindowController: rounded window content is now wrapped in a GeometryReader that frames the content to the viewport, with a comment noting the window geometry owns the viewport including embedded split views. The hosting view's sizingOptions remain [], and contentMinSize is now set after assigning contentView.
  • Window sizing changed: default height cap raised from min(720, …) to min(800, …); minimum height raised from min(520, …) to min(640, …).

Tests

  • macgitTests/AppSettingsSnapshotTests.swift
  • macgitTests/CloudSettingsDocumentTests.swift

Notes

  • fileListMode defaults to list mode, and older stored/cloud documents without the field decode to .list.
  • The commit history includes: "feat: Add tree view mode for file lists", "fix: Constrain PR window content to viewport and raise min height", and "feat: add tree view mode for create pr screen".

Note: the supplied diff was truncated, so details of the new view files and some integration changes are not fully visible here.

Summary by CodeRabbit

  • New Features
    • Choose between a plain list and a folder-based tree view for staged and changed files, commit files, and pull request changes.
    • Expand or collapse folders individually or all at once, and select files or folders in the tree view.
    • Use tree views to stage or unstage files, preview files, and access file actions where available.
    • Your file display preference is saved with your settings and restored when settings are applied.
  • Improvements
    • The create pull request window can display more content vertically.

Add FileListMode setting with list and tree options synced through settings snapshot and Firestore. Render staged, changed, and commit file lists as native tree views when tree mode is enabled.
Wrap the create pull request content in a GeometryReader so split views fill the window, enforce the minimum size after the hosting view is installed, and increase the default and minimum window heights.

📝 Walkthrough

File lists now support plain and hierarchical layouts. The selected layout is available in settings and persists locally and in cloud settings. Staged, changed, commit-detail, and pull-request draft lists can display tree layouts. The create-pull-request window also has revised sizing.

Changes: File List Tree Mode

Layer / File(s) Summary
File layout preference and persistence
macgit/Models/AppSettingsSnapshot.swift, macgit/App/AppState.swift, macgit/Services/FirestoreSettingsStore.swift, macgit/Views/Common/GeneralSettingsView.swift, macgitTests/*Settings*Tests.swift
Settings snapshots and local and cloud settings include fileListMode. General settings provides Plain list and Tree options, and restoring defaults selects list mode. Missing values default to list mode. Cloud decoding rejects unsupported values.
Shared path layout and tree construction
macgit/Views/Common/FilePathListView.swift
The shared list view switches between plain and tree content. It groups items by path, orders folders and files, and supports folder expansion and bulk expand or collapse.
Staged and changed file trees
macgit/Views/FileStatus/FileStatusTreeNativeList.swift, macgit/Views/FileStatus/FileStatusView.swift
Staged and changed file sections use the shared layout control and native tree rows. The rows connect folder and file selection, staging, conflict details, menus, and drag actions.
Commit file trees and view integration
macgit/Views/History/CommitFileTreeNativeList.swift, macgit/Views/History/CommitFileListView.swift, macgit/Views/History/HistoryCommitDetailView.swift, macgit/Views/MainWindow/MainWindowView+PullRequestActions.swift, macgit/Views/PullRequests/PullRequestDraftChangesView.swift
Commit file lists add tree rows and layout controls, with selection, opening, and patch-menu behavior. History detail and pull-request draft views enable the controls. The pull-request preparation view receives appState through the environment.

Create Pull Request Window

Layer / File(s) Summary
Window sizing and hosted content
macgit/App/CreatePullRequestWindowController.swift
The maximum window height increases to 800 points and the minimum content height increases to 640 points, subject to the window size. Hosted content is sized to the available geometry.

Review comments at @macgit/Views/FileStatus/FileStatusTreeNativeList.swift:
- Around line 17-31: Update FileStatusTreeNativeList to accept onDrop and
onDropTargetChanged callbacks, and implement its table-view drop validation and
acceptance methods so file drops stage or unstage files according to the target
section and update the drop highlight. In FileStatusView.nativeTreeList, pass
the existing handleFileDrop and target-change handlers, matching the behavior of
FileStatusNativeList.

Review comments at @macgit/Views/FileStatus/FileStatusView.swift:
- Around line 492-531: Add only a double-click binding in
FileStatusTreeNativeList alongside the existing table.action setup, targeting
its double-click handler so double-clicking a file invokes the supplied
onQuickAction callback.

Review comments at @macgit/Views/History/CommitFileListView.swift:
- Around line 94-113: Update selectTreeFile to calculate Shift-selection ranges
from the displayed tree rows rather than changes, passing the current rows into
the selection handler and including only file rows within the range. Preserve
the existing Command-toggle and single-selection behavior.
