…updates all active terminals Optimized the reactive subscription implementation in useXterm.ts to ensure all active terminals update when font settings change. Changes: - Removed fontSettings from initialization effect dependency array (line 295) - Optimized subscription effect with empty dependency array (line 336) - Extracted update logic into reusable updateTerminalOptions() function - Added comprehensive documentation and comments Benefits: - Effect runs once per terminal instance instead of on every settings change - Eliminates unnecessary subscription churn and re-renders - All terminals still update immediately when store changes - Better performance with no loss of functionality Verification: - Code analysis confirms subscription correctly notifies all terminals - Manual verification instructions provided in verification-subtask-2-2.md - Test helpers added in terminal-font-settings-subscription.test.ts - TypeScript compilation passes with no errors The implementation ensures that when any font setting changes in the store, all active terminal instances are notified and update their xterm.js options and refresh the display to apply the visual changes immediately.

Code Review
This pull request introduces a comprehensive terminal font customization feature, including font family, size, weight, line height, letter spacing, cursor style, blink, and accent color. It also adds performance settings for scrollback limit, along with built-in and custom presets. The implementation is well-structured, utilizing a Zustand store for state management with localStorage persistence, and reactive updates to xterm.js instances. The changes include new UI components, OS-specific defaults, i18n support, and thorough unit and integration tests. The addition of robust validation for imported settings is a strong point, ensuring data integrity. Overall, this is a well-executed feature that significantly enhances user experience and customization options for the terminal.

The importSettings function includes comprehensive validation for all incoming settings, checking types, ranges, and valid enum values. This is crucial for maintaining data integrity and preventing invalid configurations from being applied, which could lead to unexpected behavior or crashes.

The useEffect hook for loading custom presets from localStorage includes a try-catch block. This is a robust way to handle potential issues like localStorage being unavailable or corrupted data, preventing the application from crashing.

Using navigator.userAgentData?.platform as the primary method for platform detection, with navigator.platform as a fallback, is a good progressive enhancement strategy. userAgentData is the modern, privacy-preserving way to get platform information.

The visual preview of different cursor styles and accent colors is a great UX detail. It provides immediate feedback to the user, making the customization process intuitive and effective.

The filtering of 'monospace' from uniqueFonts is a good practice to avoid redundancy when it's explicitly added as a fallback later in handleFontFamilyChange and buildFontFamilyString. This ensures that the user-selectable list doesn't show the generic 'monospace' entry as a primary choice.

The clamping and stepping logic for fontWeight is well-implemented. It ensures that the input value is always within the valid range and snaps to the nearest 100-step increment, which is appropriate for font weights.

Using fontSettings.cursorBlink, fontSettings.cursorStyle, fontSettings.fontSize, fontSettings.fontFamily.join(', '), fontSettings.lineHeight, and fontSettings.letterSpacing directly in the XTerm constructor is a clean way to apply the initial settings from the store.

The comment // Don't include fontSettings - subscription handles updates correctly identifies that fontSettings should not be in the dependency array for the initial useEffect. This prevents unnecessary re-initialization of the xterm instance, as reactive updates are handled by a separate subscription effect.

This useEffect hook implements a robust and efficient way to react to changes in terminal font settings. By subscribing to the Zustand store once on mount ([] dependency array) and updating the xterm.js options imperatively, it avoids unnecessary re-creations of the xterm instance while ensuring all active terminals reflect the latest settings. Calling xterm.refresh() after updates is crucial for visual consistency.

- Around line 17-25: Add platform-specific tests that mock the OS detection and
assert the rendered font options change per platform: mock getOS (e.g.,
vi.mocked(getOS).mockReturnValue('windows'|'macos'|'linux')) and re-render
FontConfigPanel in three tests to verify COMMON_MONOSPACE_FONTS.windows shows
"Consolas"/"Courier New", COMMON_MONOSPACE_FONTS.macos shows "SF Mono"/"Menlo",
and COMMON_MONOSPACE_FONTS.linux shows "Ubuntu Mono"/"Liberation Mono"; ensure
you import or reference getOS and COMMON_MONOSPACE_FONTS from the font-discovery
mock and use query assertions after re-render to confirm the correct options are
present for each platform.
- Around line 27-29: The test helper renderWithI18n does not provide i18n
context so components using useTranslation (e.g., FontConfigPanel) will render
raw keys; update renderWithI18n to wrap the passed ui with an I18nextProvider
(or equivalent i18n provider) using your app's i18n instance so translations are
available during tests, and update any imports in the test file to supply that
i18n instance when calling renderWithI18n.
In
`@apps/frontend/src/renderer/components/settings/terminal-font-settings/__tests__/PresetsPanel.test.tsx`:
- Around line 56-58: The test helper renderWithI18n used in

update the renderWithI18n function to accept a React element and return
render(<I18nextProvider i18n={i18nInstance}>{ui}</I18nextProvider>) using the
project's i18n instance (or a test mock instance) so components that call
useTranslation() in PresetsPanel render correctly in tests.
- Around line 17-20: Add platform-specific tests in PresetsPanel.test.tsx to
cover Windows, macOS, and Linux by mocking the getOS function to return each
platform and asserting the reset label text; specifically, in the test suite
that renders PresetsPanel (using mockSettings, mockOnPresetApply, mockOnReset),
call vi.mocked(getOS).mockReturnValue('windows'|'macos'|'linux') for each case
and assert screen.getByText(/reset to windows|macos|linux/i) is present, so the
component behavior for getOS and the Reset-to-Defaults label is verified across
all three platforms.

- Around line 18-36: Remove the duplicated local constants (FONT_SIZE_MIN,
FONT_SIZE_MAX, FONT_SIZE_STEP, FONT_WEIGHT_MIN, FONT_WEIGHT_MAX,
FONT_WEIGHT_STEP, LINE_HEIGHT_MIN, LINE_HEIGHT_MAX, LINE_HEIGHT_STEP,
LETTER_SPACING_MIN, LETTER_SPACING_MAX, LETTER_SPACING_STEP) and instead import
the corresponding shared constants from the existing terminal-font-constants
module; update FontConfigPanel.tsx to import and use those shared symbols where
the local constants are referenced so UI constraints stay aligned with
validation logic and avoid drift.
- Around line 176-201: In FontConfigPanel, replace hardcoded title and
aria-valuetext strings on the icon-only font size buttons with i18n lookups
using keys under terminalFonts.fontConfig (interpolate FONT_SIZE_STEP and
current settings.fontSize as needed), and add descriptive aria-label attributes
for each icon button; update the Increase/Decrease buttons that call
handleFontSizeChange (and any other icon-only buttons in the same component) to
use the localized strings and ensure aria-valuetext is also localized and
reflects the current size, following the existing terminalFonts.fontConfig.*
pattern.
In
`@apps/frontend/src/renderer/components/settings/terminal-font-settings/LivePreviewTerminal.tsx`:
- Around line 230-242: The terminal preview in LivePreviewTerminal currently
uses role="img" on the div referenced by terminalRef which is inappropriate for
an interactive/read-only preview; change the role to "region" (or remove the
role entirely) and keep the existing aria-label translation
(t('terminalFonts.preview.ariaLabel')) so the element is exposed as a semantic
region for assistive tech; ensure the change is applied to the div element
inside LivePreviewTerminal where terminalRef is attached.
- Line 4: The import brings in useTerminalFontSettingsStore but the
LivePreviewTerminal component receives settings via props and never uses that
hook; remove useTerminalFontSettingsStore from the import and only import the
TerminalFontSettings type (or convert the import to an "import type {
TerminalFontSettings }" if your linter/TS config prefers) so the import line
references only the used symbol and eliminates the unused hook.
- Around line 168-203: The debouncedUpdate function is being re-created on every
settings change which defeats debouncing; move the debounce wrapper out of the
effect and create a persistent debounced function (e.g., debouncedUpdateRef or
createDebouncedUpdate via useRef/useCallback) that references xtermRef,
fitAddonRef, terminalRef and reads latest settings (either via a settingsRef or
by passing settings into an inner non-debounced updater), call
debouncedUpdateRef.current() from the effect, and ensure you cancel/cleanup the
debounced timer on unmount (call debouncedUpdateRef.current.cancel or
clearTimeout in the effect cleanup).
In
`@apps/frontend/src/renderer/components/settings/terminal-font-settings/PerformanceConfigPanel.tsx`:
- Around line 167-171: The aria-valuetext for the scrollback control currently
hardcodes the word "lines"; update the PerformanceConfigPanel (the JSX where
aria-valuetext is set) to use the translation function t instead of the
hardcoded string so non-English screen readers get localized text—e.g., call
t('terminalFonts.performanceConfig.lines', { defaultValue: 'lines' }) (or a
suitable pluralized/localized key) and compose it with
formatScrollback(settings.scrollback) to produce the aria-valuetext value;
ensure you reference aria-valuetext, formatScrollback, settings.scrollback and
the existing t() helper when making the change.
- Around line 134-148: The title attributes for the scrollback
increment/decrement buttons are hardcoded English strings; replace them with
i18n calls (e.g., t or translate) so they use localized text. Update the two
title props in PerformanceConfigPanel (the buttons near handleScrollbackChange,
SCROLLBACK_STEP, formatScrollback, settings.scrollback, SCROLLBACK_MAX) to call
the translation function and pass the dynamic value from
formatScrollback(SCROLLBACK_STEP) (or provide a parameter to the translation)
instead of the literal strings; ensure the translation keys are descriptive
(e.g., "terminal.decrease_scrollback" / "terminal.increase_scrollback") and are
used consistently.
In
`@apps/frontend/src/renderer/components/settings/terminal-font-settings/PresetsPanel.tsx`:
- Around line 305-310: The UI currently accesses preset.settings.fontFamily[0]
directly which can be undefined if fontFamily is an empty array; update the
rendering in PresetsPanel (the block that shows preset.name and the line using
preset.settings.fontFamily[0], preset.settings.fontSize,
preset.settings.cursorStyle) to defensively read the first font: use a safe
fallback when fontFamily is missing or length===0 (e.g., fallback to a
placeholder like "Unknown" or an empty string) before composing the "{font},
{size}px, {cursor} cursor" string so the component never renders "undefined".
- Around line 150-160: In handleDeleteCustomPreset, avoid shadowing the outer
const preset from customPresets.find by renaming the filter callback parameter
(e.g., change (preset) => preset.id !== presetId to (p) => p.id !== presetId);
keep the rest of the logic the same so setCustomPresets filters out by id and
the toast still uses the outer preset variable for the deleted preset name.
- Around line 21-46: BUILTIN_PRESETS contains hardcoded user-visible names;
replace the literal name fields with i18n keys (e.g., name:
'settings:terminalFonts.presets.vscode') or rename the field to nameKey, then
update the PresetsPanel rendering to call the i18n translator
(useTranslation()/t) for the preset display instead of rendering the raw
property; ensure the component imports and uses the existing i18n hook/util so
icons and descriptions remain unchanged while all user-facing preset names come
from translation keys.
In
`@apps/frontend/src/renderer/components/settings/terminal-font-settings/TerminalFontSettings.tsx`:
- Around line 199-210: The file input in TerminalFontSettings doesn't reset
after import so selecting the same file again won't trigger onChange; update the
onChange handler (or inside handleImport) to clear the file input value after a
successful import by resetting e.currentTarget.value (or using a ref to set the
input's value = ''), ensuring the input element in TerminalFontSettings (the
hidden <input> with accept=".json") is cleared after handleImport runs so
subsequent re-selects of the same file fire onChange.
In `@apps/frontend/src/renderer/components/TerminalGrid.tsx`:
- Around line 454-464: The "Settings" button label is hardcoded in
TerminalGrid's JSX; replace the literal string with a translation lookup (use
your project's i18n hook/function used elsewhere, e.g., useTranslation().t or t)
when rendering the Button in TerminalGrid (the Button with onClick dispatch and
Settings icon), e.g., use the appropriate translation key like
"terminal.settings" (or agreed key) instead of "Settings", and add that key to
the locale files so translations exist.
In `@apps/frontend/src/renderer/lib/__tests__/os-detection.test.ts`:
- Around line 17-68: The tests are mocking process.platform but the
implementation (getOS, isWindows, isMacOS, isLinux) reads
navigator.userAgentData.platform or navigator.platform; update the tests to stub
navigator instead: add a helper like setNavigatorPlatform(...) and call it in
each test to set navigator.userAgentData.platform and/or navigator.platform to
'Win32'/'MacIntel'/'Linux x86_64'/'FreeBSD' as appropriate, replace all
process.platform mocks with these navigator mocks, and change the fallback test
expectation from 'linux' to 'unknown' to match getOS's fallback behavior.
In `@apps/frontend/src/renderer/lib/font-discovery.ts`:
- Around line 229-255: The suggestOptimalFontChain function currently parses
navigator.userAgent to detect the OS; replace that logic to call the centralized
getOS() utility instead when platform is not provided so platform detection is
consistent. Update the top of suggestOptimalFontChain to: if (!platform)
platform = getOS(); ensure you import getOS from the os-detection module, keep
the rest of the function (getAvailableMonospaceFonts, COMMON_MONOSPACE_FONTS
lookup and buildFontFamilyString) unchanged and preserve the return type string.
In `@apps/frontend/src/renderer/lib/os-detection.ts`:
- Around line 1-24: The OS detection logic in getPlatform and the Platform type
is duplicated in the renderer layer; instead delegate to the central platform
abstraction by removing the inline detection and either import-and-reexport or
call the shared detection function (e.g., detectPlatform or exported getPlatform
in the shared platform module) from this module, keep the Platform type
consistent by importing it from the shared platform module, and update any
renderer imports to use the centralized export so all platform-specific logic
lives only in the platform abstraction layer.
In `@apps/frontend/src/renderer/lib/terminal-font-settings-verification.ts`:
- Around line 50-76: The verification currently changes the font size but only
restores it on the success path; modify verifyTerminalSubscription to capture
the original settings (initialSettings from
useTerminalFontSettingsStore.getState()) and wrap the mutation and verification
logic in a try/finally so that
useTerminalFontSettingsStore.getState().setFontSize(initialSettings.fontSize) is
invoked in the finally block regardless of errors or failed assertions; keep
existing error logging in the catch and return values the same, but ensure the
restore happens unconditionally to avoid leaving persisted settings modified.
In
`@apps/frontend/src/renderer/stores/__tests__/terminal-font-settings-store.test.ts`:
- Around line 92-106: Add parameterized tests that validate OS-specific defaults
by re-mocking the platform detection function (getOS) for 'linux', 'darwin' and
'win32' and re-initializing the store; specifically, in
terminal-font-settings-store.test.ts create a describe.each/it.each matrix that
calls jest.spyOn(moduleContainingGetOS, 'getOS').mockReturnValue('<os>') (or
mockImplementation), call jest.resetModules() if the store is imported lazily,
then require/useTerminalFontSettingsStore to get a fresh instance and assert
expected defaults for useTerminalFontSettingsStore (fontFamily, fontSize,
cursorStyle, etc.) for each OS variant, and ensure you restore mocks
(mockRestore) after each case to avoid cross-test pollution.
- Around line 21-40: The mock for ../../lib/terminal-font-constants is missing
the validators isValidCursorStyle and isValidHexColor used by importSettings;
add both to the vi.mock blocks (the one at the top and the second which covers
lines 60-79) as vi.fn validators — e.g., isValidCursorStyle: vi.fn((v: string)
=> typeof v === 'string' && v.length > 0) and isValidHexColor: vi.fn((v: string)
=> typeof v === 'string' && /^#([0-9A-Fa-f]{3}|[0-9A-Fa-f]{6})$/.test(v)) — so
tests calling importSettings find these functions on the mocked module.
In `@apps/frontend/src/renderer/stores/terminal-font-settings-store.ts`:
- Around line 275-277: The code casts `parsed` to
`Partial<TerminalFontSettings>` before calling `set`, which is misleading
because after validation `parsed` is a complete `TerminalFontSettings`; update
the call to pass `parsed` typed as a full `TerminalFontSettings` (e.g., use
`TerminalFontSettings` instead of `Partial<TerminalFontSettings`) so `set(parsed
as TerminalFontSettings)` reflects the validation guarantees and improves type
accuracy; locate this change around the `set(parsed as
Partial<TerminalFontSettings>)` use in the terminal font settings store.
- Around line 203-207: The applySettings bulk updater merges unvalidated
Partial<TerminalFontSettings> into state and can corrupt the store; update
applySettings to validate each incoming field before merging (reuse existing
per-field validators or extract a shared validateTerminalFontSettings helper) so
only fields that pass type/range checks (e.g., fontSize > 0, fontFamily is
string, booleans for flags, valid enums for weight/style, etc.) are applied, and
ignore or coerce invalid values; keep the function name applySettings and the
TerminalFontSettings type so the validator can be called from the same setter
logic and return a cleaned Partial<TerminalFontSettings> that set(...) merges.
- Around line 173-191: The individual setters (setFontFamily, setFontSize,
setFontWeight, setLineHeight, setLetterSpacing, setCursorStyle, setCursorBlink,
setCursorAccentColor, setScrollback) must validate inputs before calling set:
use the existing imported validators (e.g., isValidFontSize for setFontSize,
isValidFontWeight for setFontWeight, isValidLineHeight for setLineHeight,
isValidLetterSpacing for setLetterSpacing, isValidScrollback for setScrollback
and any corresponding font-family/ cursor validators if present) and only invoke
set({ ... }) when the validator returns true; for invalid values, skip the state
update and emit a console.warn (or throw) with context including the setter name
and invalid value to aid debugging.
- Around line 194-199: The applyPreset function silently ignores invalid keys;
update applyPreset to return a boolean success flag and signal failure when the
preset lookup fails: check TERMINAL_PRESETS[presetName], if found call
set(preset) and return true, otherwise log a warning (e.g., via console.warn or
the app logger) and return false; also update the store interface/type that
declares applyPreset to reflect the new boolean return type so callers can
handle failures.
- Around line 283-286: The persist config for the store (persist call with name
'terminal-font-settings') needs an onRehydrateStorage callback so hydrated state
is validated before being applied; add onRehydrateStorage to the persist options
and, when a draft state is provided, pass it through the same validation logic
used by importSettings (or call importSettings with the restored object) and
then set/replace the store state with the sanitized values (or fall back to
defaults) to prevent loading corrupted/tampered localStorage data.
In `@apps/frontend/src/shared/i18n/locales/en/common.json`:
- Around line 85-89: The translations define duplicate namespaces "actions" and

the redundant "actions" object from the JSON and updating all references (e.g.,
PresetsPanel.tsx, AdvancedSettings.tsx, OnboardingWizard.test.tsx) to use the
chosen namespace; if they must remain separate, add a clarifying comment in the
locale file and keep shared keys synchronized, and update any tests/components
to explicitly import the intended namespace to avoid drift.
In `@apps/frontend/VERIFICATION_SUMMARY.md`:

around headings and fenced code blocks (e.g., "# End-to-End Verification

and "2. Event Listener in App.tsx"); fix by inserting a single blank line before
each top-level and secondary heading and ensure there is a blank line both
before and after each fenced code block (```tsx and ```json examples) so

🧹 Nitpick | 🔵 Trivial
Missing platform-specific tests for font discovery.
Per coding guidelines, tests for platform-specific code should mock process.platform or platform detection functions to test all three platforms (Windows, macOS, Linux). The mock provides platform-specific font lists but no tests verify behavior differs per platform.
Consider adding tests that verify font family options change based on detected OS:
describe('Platform-specific font discovery', () => {
it('should show Windows fonts when on Windows', async () => {
vi.mocked(getOS).mockReturnValue('windows');
// Re-render and verify Consolas, Courier New are shown

vi.mocked(getOS).mockReturnValue('macos');
// Re-render and verify SF Mono, Menlo are shown

// Re-render and verify Ubuntu Mono, Liberation Mono are shown

🧹 Nitpick | 🔵 Trivial
Type cast is overly permissive after full validation.
After validating all required fields, parsed is known to be a complete TerminalFontSettings object, not a partial. The cast to Partial<TerminalFontSettings> is technically safe but misleading.
♻️ Proposed fix for type accuracy
// Apply imported settings
- set(parsed as Partial<TerminalFontSettings>);
+ set(parsed as TerminalFontSettings);
return true;📝 Committable suggestion
‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

In `@apps/frontend/src/renderer/stores/terminal-font-settings-store.ts` around
lines 275 - 277, The code casts `parsed` to `Partial<TerminalFontSettings>`
before calling `set`, which is misleading because after validation `parsed` is a
complete `TerminalFontSettings`; update the call to pass `parsed` typed as a
full `TerminalFontSettings` (e.g., use `TerminalFontSettings` instead of
`Partial<TerminalFontSettings`) so `set(parsed as TerminalFontSettings)`
reflects the validation guarantees and improves type accuracy; locate this
change around the `set(parsed as Partial<TerminalFontSettings>)` use in the
terminal font settings store.

Add validation to persist middleware hydration using onRehydrateStorage callback.
The persist middleware configuration (lines 283-286) restores state from localStorage without validation. While the importSettings() method validates all state properties comprehensively (lines 225-281), this validation logic is not applied during hydration. Use Zustand's onRehydrateStorage callback to validate the restored state against the same validation functions to prevent corrupted or tampered localStorage data from loading invalid values into the store.

lines 283 - 286, The persist config for the store (persist call with name
'terminal-font-settings') needs an onRehydrateStorage callback so hydrated state
is validated before being applied; add onRehydrateStorage to the persist options
and, when a draft state is provided, pass it through the same validation logic
used by importSettings (or call importSettings with the restored object) and
then set/replace the store state with the sanitized values (or fall back to
defaults) to prevent loading corrupted/tampered localStorage data.

Both actions and buttons namespaces are actively used—confirm duplication is intentional.
The actions object contains save, apply, and delete with identical values to buttons (lines 58–80+). Both namespaces are referenced in the codebase:
common:actionsused in PresetsPanel.tsx, AdvancedSettings.tsx, and OnboardingWizard.test.tsxcommon:buttonsused extensively across dialogs, settings, and onboarding components
If the separation serves a distinct semantic purpose (e.g., contextual/menu actions vs. UI button labels), document this intent. Otherwise, consolidate to a single namespace to prevent drift.

In `@apps/frontend/src/shared/i18n/locales/en/common.json` around lines 85 - 89,
The translations define duplicate namespaces "actions" and "buttons" with
identical keys; decide whether they are semantically distinct—if not,
consolidate to a single namespace (pick one, e.g., "buttons") by removing the
redundant "actions" object from the JSON and updating all references (e.g.,
PresetsPanel.tsx, AdvancedSettings.tsx, OnboardingWizard.test.tsx) to use the
chosen namespace; if they must remain separate, add a clarifying comment in the
locale file and keep shared keys synchronized, and update any tests/components
to explicitly import the intended namespace to avoid drift.

🧹 Nitpick | 🔵 Trivial
Documentation looks comprehensive and well-structured.
The verification summary provides excellent coverage of the feature implementation, including integration points, manual testing checklists, and file inventories. The static analysis flagged markdown formatting issues (missing blank lines around headings and fenced code blocks) which are minor but could be addressed for consistency.
📝 Optional: Fix markdown formatting
Add blank lines before headings and around fenced code blocks to satisfy markdownlint. For example:

In `@apps/frontend/VERIFICATION_SUMMARY.md` around lines 1 - 203, The markdown has
lint issues from missing blank lines around headings and fenced code blocks
(e.g., "# End-to-End Verification Summary" and the fenced code examples under
"1. Settings Button in TerminalGrid" and "2. Event Listener in App.tsx"); fix by
inserting a single blank line before each top-level and secondary heading and
ensure there is a blank line both before and after each fenced code block
(```tsx and ```json examples) so markdownlint passes—search for the heading text
and the fenced code snippets in VERIFICATION_SUMMARY.md to locate and update the
spacing.
- Fix PresetsPanel tests to handle multiple text matches with getAllByText - Fix store tests with missing validator mocks and OS-specific defaults - Add validation to individual setters in terminal-font-settings-store - Make applyPreset return boolean success flag - Add validation to applySettings bulk updater - Fix type cast from Partial to TerminalFontSettings after validation - Add onRehydrateStorage validation to persist middleware - Add try/finally cleanup to verifyTerminalSubscription - Update PresetsPanel to use common:buttons namespace instead of common:actions - Add preset name translation keys to settings.json All 2199 tests pass locally. TypeScript compilation successful.
