Summary

Adds a Settings Hooks pane, matching the Mac PreferencesHooksPane. Before this change, Windows had only an "Enable hooks" switch in Advanced, and you had to edit hooks.json by hand to add rules.

  • New tab: Settings > Hooks, with tab id hooks. It sits between Advanced and About, as on the Mac sidebar. The id is added to the backend whitelist in surface_target.rs and to the frontend SettingsTabId / TAB_META, so CODEXBAR_PROOF_MODE=settings:hooks works.
  • Enable hooks: the switch writes hooks.json enabled and settings.json hooks_enabled together (Mac SettingsStore+Config.swift:235-270). The trust warning sits under it: "Hooks can execute local commands on this PC. Only configure commands you trust."
  • Rules editor: add or delete rules, up to 32 (MAX_RULES). Each rule has an enable switch, an event (the 7 hook events), a provider ("Any provider" or one provider), a quota_low threshold, an executable and arguments (up to 32). Edits save straight away, as on the Mac. Text fields save when they lose focus or on Enter.
  • New bridge commands: get_hooks_config and save_hooks_config. The backend validates every save: an unknown event, more than 32 rules, or more than 32 arguments on a rule is refused with a readable error. The UI cap is not the only check. When hooks.json can't be read, the pane locks and shows why instead of overwriting the file.
  • Advanced tab: the old Hooks switch is removed; it now lives in the Hooks pane.

Mac reference (upstream 0.70.0 Sources/CodexBar)

  • PreferencesHooksPane.swift:
    • :10-20 pane layout;
    • :22-43 enable switch and warning;
    • :62-198 rules editor (add, delete, event and provider pickers, arguments);
    • :200-212 rule cap.
  • SettingsStore+Config.swift:235-270: the master switch writes both flags.
  • PreferencesSidebar.swift:42: the Hooks entry in the sidebar.

Commands run on the head (706d436)

CARGO_TARGET_DIR=W:\cargo-target\settings-hooks. Heavy steps ran under the E-core wrapper. CI was not set.

  • Rust: 14 tests in core/hooks.rs and commands/hooks.rs, covering validation, round trips, both flags written, and the rule cap.

Real-window proof

The proof used a debug build of this head with the proof-kit dirs/reqwest shim, which is not committed. It ran against an isolated home with CODEXBAR_PROOF_MODE=settings:hooks. CDP drove the clicks and cua-driver took the screenshots. The window was on the secondary monitor. The real %APPDATA%\CodexBar was never touched.

The steps log is W:/mac-parity/report/lane-s/pr1/steps.jsonl (run lane-s-pr1-20261012-032112, 0 failures). It shows:

  • The pane, subtitle and trust warning are shown, and Enable starts off. Shot: shots/01-hooks-empty-warning.png.

  • "+ Add rule" adds a rule. Typing C:\Tools\my-command.exe and an argument --notify lands in the isolated hooks.json. Shot: shots/02-rule-added.png.

  • After the app is killed and relaunched on the same home, the rule is still there with the same executable and argument. Shot: shots/03-rule-persisted-after-reopen.png.

  • The Enable switch:

    State hooks.json enabled settings.json hooks_enabled (DPAPI-decrypted)
    After switching on true true
    After switching off false false

    Shot: shots/04-enabled.png.

  • Adding 31 more rules gives 32 rows, "+ Add rule" is disabled, and hooks.json holds 32 rules. Shot: shots/05-32-rule-cap.png.

  • A direct save_hooks_config with 33 rules is refused: hooks support at most 32 rules (got 33).

The screenshots show the isolated proof path in the footer, which includes the local Windows user name. They contain no email addresses or credentials.

Open questions (default chosen)

  1. Footer with the hooks.json path: Windows-only. The Mac has no footer. Kept, because Windows users may edit the file by hand. Default: keep.
  2. Partly-on caption: shown when only one of the two flags is on, for example after a hand edit. Not on the Mac. Default: show the caption, and let the switch write both flags.
  3. Load and save error captions: inline under the pane. The Mac shows no error text. Default: inline caption.
  4. Save timing for text fields: they save on blur or Enter, not on every keystroke as on the Mac. This avoids a disk write per key. Default: blur or Enter.
  5. Translations: the new strings are translated in all 10 locales, without a native-speaker review. Default: ship them as they are.

Summary by CodeRabbit

  • New Features
    • Added a Hooks tab in Settings to enable hooks and manage rules by event, provider, usage threshold, executable, and arguments.
    • Added a warning about hooks running local commands, plus status messages for partial activation and configuration load or save errors.
    • Added translated Hooks settings labels and guidance in supported languages.
  • Bug Fixes
    • Hook configuration now identifies unreadable files and validates event names, rule counts, and argument limits before saving.
    • Saving hook configuration replaces the file atomically.

A rapid pair of hook-rule edits can lose one saved change, and a Rust test fails on Unix hosts. These are bounded issues without an established broader production failure.

Build the next rule list from the latest drafts, not the render-time rules.

The onChange and onDelete callbacks close over rules from the last render. persist calls setRules(next) at once. If a user commits two edits before React re-renders, the second edit starts from the stale list. Example: blur one argument field and then click "+ Add argument" in the same tick. The second save overwrites the first edit. Use a ref that persist updates synchronously, and read the current list from that ref.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Make the executable path in the rule_with helper platform-neutral.

rule_with hard-codes C:\Tools\notify.exe. On non-Windows targets this path is not absolute. a_rule_over_the_argument_cap_never_matches asserts rule_with(32).matches(&event). That assertion fails on non-Windows hosts. The tests at lines 131-152 already use #[cfg(windows)] to select an absolute path. The same issue affects config_matching_respects_enabled_flag at line 162, which was not changed here. The test at lines 292-318 also compares against C:\Tools\a.exe. That test passes because it only compares PathBuf values. Use a cfg-selected absolute path in the helper.

Proposed fix
-        executable: PathBuf::from(r"C:\Tools\notify.exe"),
+        executable: if cfg!(windows) {
+            PathBuf::from(r"C:\Tools\notify.exe")
+        } else {
+            PathBuf::from("/usr/bin/true")
+        },
