1. ThemeSettings: change 'auto' radio value to 'system' to match
the v5 settingsSchema enum. Storing 'auto' silently wipes all
settings on next launch.
2. UpdateBanner: render an 'available' branch so users see a CTA
when a new version is detected (the store already had this state,
but the banner was silent). Added a test.
3. feed-config: remove the unused resolveFeedUrl / FEEDS exports.
feedConfigFor is the actual implementation used by the IPC
handler. Updated tests to match.
4. main/index.js: tighten app:open-external regex to https:// only.
The v5.0.0 React UI shipped with a working surface but had a number of
features left as 'wired in a later phase' or broken by missing IPC
plumbing. This commit completes the wiring end-to-end and proves the
behaviour with the run-desktop driver.
Toolbar format buttons (Toolbar.tsx)
- Bold, Italic, Unordered/Ordered list, Code, Link now dispatch real
commands instead of being permanently disabled.
New module: src/renderer/lib/editor-commands.ts
- Module-level singleton holding the active CodeMirror EditorView.
- toggleBold/Italic/Code/CodeBlock, toggleUnorderedList/OrderedList,
insertLink, setHeadingLevel, scrollToLine, undo, redo, insertSnippet.
- CodeMirrorEditor mounts the view via setActiveView on mount and
nulls it on unmount, so commands land on the focused buffer.
register-menu-commands.ts
- file.confirmClose: prompts before closing a dirty tab via the
confirm modal; otherwise closes silently.
- app.quit: prompts before quitting if any buffer is dirty; uses
the new ipc.app.quit channel.
- short-cuts.show: shows the keyboard shortcut list in a confirm dialog.
- editor.bold/italic/code/list.*/link/undo/redo/heading.*: drive the
active editor.
- find.toggle: dispatches mc:find-toggle for any listening component.
- view.sidebarPanel/bottomPanel: navigate between sidebar sections
via the new data-testid buttons; bottom panel toggles the REPL.
- font.size: increase/decrease/reset on editorFontSize (10..28).
- theme.loadCustomCss/clearCustomCss: pick and clear the custom CSS
path on the settings store.
- template.load: inserts a bundled markdown skeleton at the cursor.
- print.preview/previewStyled: emit mc:print and mc:print-preview.
- file.clearRecent: clears open tabs.
- file.new: creates an untitled buffer and tab.
- editor.gotoHeading: scrolls to a given line (used by Outline and
Breadcrumb).
- view.toggleSidebar: already wired.
- file.opened: already wired (prior fix).
Sidebar Outline + Breadcrumb
- Both now click through to 'editor.gotoHeading' with the line
number extracted from the active buffer.
- Sidebar exposes data-testid for the 'view.sidebarPanel' menu action.
editor-commands sets the active view; scroll metrics flow through to
Minimap which now reads scrollRatio/visibleRatio from the editor.
Export dialogs (PDF/DOCX/HTML)
- Replaced the broken ipc.export.{pdf,docx,html,batch} calls (those
channels were not implemented in main and only CHANNEL_MISSING
was returned) with renderer-side pipelines.
- PDF: generateHtml() with @page CSS for size + margins, then
ipc.print to the main process for native print-to-PDF.
- DOCX: generateDocx() from the existing lib, then ipc.file.writeBuffer.
- HTML: generateHtml() then ipc.file.writeBuffer.
- All three dialogs use ipc.app.showSaveDialog for output path
(new IPC handler) and ipc.file.writeBuffer for the binary write
(new preload channel).
- PrintPreview now uses MarkdownRenderer instead of a raw <pre>.
New settings fields
- editorFontSize: 10..28 px (drives CodeMirror theme font-size)
- customCssPath: string|null (Theme menu wires 'load-custom-css' and
'clear-custom-css' to it).
New IPC channels
- 'app:quit', 'app:open-external', 'app:show-save-dialog',
'write-buffer' (already existed; now exposed in preload).
Tests
- Updated Toolbar test: format buttons are no longer disabled and
dispatch their command ids.
- Updated Export*D*Dialog tests to mock the new ipc surface
(ipc.print, ipc.app.showSaveDialog, ipc.file.writeBuffer) and
assert the new flow.
- Updated PrintPreview test to use ipc.print.doPrint.
- Updated phase8-toasts integration: PDF flow now goes through
ipc.print and asserts 'Sent <title> to printer'.
- register-menu-commands test: re-register 'template.load' AFTER
Harness renders so the captured-args handler is the live one.
Verification
- npm run build:renderer: success (1.6s)
- npx vitest run: 308 passed (up from 305; 3 new + unchanged)
- npx jest: 189 passed (unchanged)
- .claude/skills/run-desktop/verify-features.mjs: drove the live app
via Playwright, exercised every wired feature end-to-end, captured
11 screenshots. All verified working (editor + preview render the
file content, toolbar buttons dispatch, dialogs open, theme
toggles, outline shows headings, italic button works in editor).
Two related defects were breaking the 'open file' flow:
1. The BrowserWindow webPreferences had no preload path AND
contextIsolation: false, so contextBridge.exposeInMainWorld
threw on load and window.electronAPI was never set. Result:
every renderer-side ipc.* call returned CHANNEL_MISSING and
silently no-op'd. Toolbar Open/Save, the file menu, every
dialog — all broken.
2. The 'file.opened' IPC bridge in register-menu-commands.ts
dispatched to a 'file.opened' command that was never registered
as a handler. Even if the preload had worked, the main menu's
File -> Open would have been a no-op once it reached the
command store.
Fixes:
- window/index.js: add preload path; set contextIsolation: true
(required for contextBridge) and nodeIntegration: false
(renderer no longer needs direct Node access; everything goes
through the whitelisted preload bridge).
- file-store.ts: add openFileFromMain(path, content) that opens
a tab + editor buffer from content the main process already read
(skips the renderer's ipc.file.read since main has the bytes).
Preserves existing buffer content if the file is already open.
- register-menu-commands.ts: register 'file.opened' to call
openFileFromMain. Drop the dead 'command.palette' bridge
(no consumer, no UI, no handler).
- tests: two new cases for openFileFromMain — verifies it does
not call ipc.file.read and does not clobber user edits on
re-open.
Verified end-to-end via the run-desktop driver: triggering
file-opened from the main process with a test .md now shows the
content in BOTH the CodeMirror editor and the rendered preview
pane (plus the Outline panel picks up the H1). 497 tests pass.
- useRegisterMenuCommands: registers file.open, file.save, file.closeTab,
tab.next, tab.prev, view.toggleSidebar, view.togglePreview in command store
- useBridgeNativeMenu: useMenuAction for 13 native-menu channels
(file-save, toggle-preview, load-template-menu, etc.)
- AppShell calls both on mount
- integration test mock extended to include ipc.menu.on
- 145/145 tests pass (was 105)
- bridge between main-process menu events and the command dispatcher
- optional transform: convert raw IPC payload to command args
- extends ipc.ts with ipc.menu.on() helper
- TDD: 5 unit tests covering subscription, payload transform, no-op, unmount
- 'mod+s' / 'mod+shift+s' / 'Tab' / etc.
- mod = meta (Mac) or ctrl (others)
- suppresses when <input>/<textarea>/contentEditable focused
- preventDefault on match
- TDD: 15 unit tests covering parser, match, suppression, unmount
- useCommandStore: register/unregister/registerMany/dispatch/get
- keyed by id (e.g. 'file.open', 'view.toggleSidebar')
- TDD: 10 unit tests covering register, dispatch, unregister, batch
- foundation for Phase 6 native menu + toolbar wiring
