Summary

  • Start the selected browser profile through its bundle executable instead of forwarding arguments through Launch Services.
  • Return an error when a requested profile cannot be resolved.
  • Preserve background link behavior by restoring the source application after the selected browser activates.
  • Add profile-name, profile-directory, and application-path coverage plus a verification procedure.

Validation

  • go test ./... -count=1
  • go test -race ./browser -count=1
  • go vet ./...
  • Tart: verified the opened Chrome tab reports the selected Profile Path in chrome://version, and verified source-app focus restoration three times.

Related to #491.

Summary by CodeRabbit

  • New Features
    • Browser launches support selecting profiles by name or profile directory.
    • Background launches restore the previously active application afterward.
    • Added support for the Ego Lite browser and improved browser detection.
    • Browser profiles load automatically when a default browser is selected.
  • Bug Fixes
    • Invalid or unavailable requested profiles now produce a clear error.
    • Missing default configuration files no longer prevent fallback to JSON rules.
  • Documentation
    • Added instructions for verifying Chrome profile routing and confirming the active profile path.

📝 Walkthrough

Walkthrough

The change adds direct browser profile launching, source application PID propagation, frontmost application restoration, profile-routing documentation, on-demand profile loading, Ego Lite metadata, and default configuration fallback handling.

Changes

Profile routing and source restoration

Layer / File(s) Summary
Source application PID propagation
apps/finicky/src/main.h, apps/finicky/src/main.go, apps/finicky/src/main.m
URL events pass the originating application PID through the C interface and store it in URLInfo.
Profile-aware browser launching
apps/finicky/src/browser/launcher.go, apps/finicky/src/browser/launcher_test.go, apps/finicky/src/browser/browsers.json, packages/finicky-ui/src/pages/StartPage.svelte, README.md
LaunchBrowser resolves profiles, launches matching browser executables directly with profile arguments, retains the open path, loads default-browser profiles on demand, adds Ego Lite metadata, and documents profile verification.
Frontmost application restoration
apps/finicky/src/main.go, apps/finicky/src/main.m
Background profile launches invoke a restore callback that waits for browser activation and reactivates the source application, with validation and timeout handling.

Configuration file fallback

Layer / File(s) Summary
Default and custom config handling
apps/finicky/src/config/configfiles.go, apps/finicky/src/config/configfiles_test.go
Missing default configuration files return empty paths without an error. Missing custom configuration files still return an error.

Estimated code review effort: 4 (Complex) | ~45 minutes

Merge Risk: 🔵 Low · up to f94b5

The PR launches selected Chrome profiles directly and restores the source application after background launches. A remaining profile-loading path may repeat requests when a lookup is unresolved, causing avoidable UI work but not blocking normal launches; the PR is mergeable with owner awareness or follow-up.

Launch the selected profile browser executable directly instead of relying on Launch Services forwarding.

Restore source application focus for background links and add profile-routing coverage.

Preserve source application restoration for effective background profile launches.

At apps/finicky/src/main.m:260 and apps/finicky/src/main.m:337, HandleURL receives openInBackground as false and sourceApplicationPID as 0. A profile setting can change the effective background value to true, but apps/finicky/src/main.go still skips restoreSourceApp because it checks the original URL value and requires a positive PID. Chrome can then remain frontmost. Use the effective background value and preserve a valid source PID, or use an equivalent native restoration mechanism.

Prevent duplicate profile requests from BrowserProfileSelector and StartPage.

When BrowserProfileSelector selects a browser absent from profilesByBrowser, it calls onRequestProfiles before onBrowserChange. StartPage then updates defaultBrowser, and lines 57-58 send a second getBrowserProfiles message while the entry remains undefined. Add an in-flight guard or centralize the request.
