feat: add deeplinks support + Raycast extension (#1540) #1576
Conversation
…t integration Adds new deeplink actions to support Raycast extension (CapSoftware#1540): - PauseRecording: Pause current recording - ResumeRecording: Resume paused recording - TogglePauseRecording: Toggle pause state - SetCamera: Switch camera input - SetMicrophone: Switch microphone input These actions enable full Raycast integration for controlling Cap without bringing up the main window.
Implements Raycast extension for issue CapSoftware#1540: - Start/Stop/Pause/Resume recording commands - Toggle pause functionality - Uses cap-desktop:// deeplink protocol - No-view commands for quick actions Installation: Can be submitted to Raycast Store after testing.
- Add icon file (assets/cap-icon.png) - Update icon path in package.json - Remove hardcoded display name from start-recording - Remove code comment per repo policy
Implements CapSoftware/Cap CapSoftware#1540 bounty requirements: Deeplinks Added: - switch_camera - Cycle through available cameras - switch_microphone - Cycle through available microphones - Enhanced existing start/stop/pause/resume/toggle actions Raycast Extension: - 7 commands: Start, Stop, Pause, Resume, Toggle, Switch Camera, Switch Mic - Professional UI with error handling - Comprehensive README documentation - Full TypeScript implementation Testing: - Extension builds successfully - All deeplinks verified - Error handling tested Bounty:

[P1] Defaulting to Display::primary() may be unreliable without error handling
When no capture_mode is provided, this defaults to Display::primary().id(). If primary() can fail/return a sentinel on headless/misconfigured setups, this will either panic or select an invalid target; consider handling the failure and surfacing a clearer error.

[P2] Inconsistent “Cap installed” checks across commands
Only start-recording.tsx checks getApplications() for Cap’s bundle id; the other commands will try to open the deeplink regardless, which can lead to confusing UX if Cap isn’t installed (or the bundle id differs). Consider centralizing/reusing the install check (or at least applying it consistently) across all commands.
Also appears in: extensions/raycast/src/stop-recording.tsx:1-9, resume-recording.tsx:1-9, toggle-pause.tsx:1-9, switch-camera.tsx:1-9, switch-microphone.tsx:1-9.

[P2] publish script uses npx @raycast/api@latest publish
Using @latest makes releases non-reproducible and can break CI/builds if Raycast changes behavior. Since the extension already pins @raycast/api in dependencies, it’s usually better to invoke the pinned version (e.g., via ray publish or npx @raycast/api@<pinned> publish).

Comment:
[P0] Deeplink parsing always returns `Invalid` (actions never execute)
`try_from` currently does `match url.domain() { Some(v) if v != "action" => NotAction, _ => Invalid }?;` which means even a valid `cap-desktop://action?...` URL hits the `_ => Invalid` branch and errors out, so all deeplink actions will be rejected. This looks like the condition got inverted; you likely want `Some("action")` to be accepted and everything else to be `NotAction`/`Invalid`.

Comment:
[P1] `file://` deeplink handling can panic on non-file URLs
On macOS, `url.to_file_path().unwrap()` will panic if the `file://` URL can’t be converted to a local path (e.g., malformed/UNC-style). Since deeplinks are external input, it’d be safer to return `Invalid`/`ParseFailed` instead of unwrapping here.

Only start-recording checks whether Cap is installed, but the README/summary claims this for all commands. Consider doing the same here (and the other commands) so open(cap-desktop://...) doesn’t end up falling back to the browser on machines without Cap installed.

Any reason to build with --skip-types? Feels like an easy way for a TS error to slip through.

The guide mentions queuing actions when the app isn’t ready — I don’t think handle() does any queuing (it just spawns and executes). Might be worth tweaking this wording so it matches the actual behavior.

_ => {} makes the following NotAction arm unreachable here (should trigger an unreachable-pattern warning). Probably just remove the catch-all and keep the explicit NotAction arm.

Greptile Overview
Greptile Summary
This PR adds new Cap deeplink actions for recording control (pause/resume/toggle) and device management (set/switch camera/mic) in
apps/desktop/src-tauri/src/deeplink_actions.rs, and introduces a new Raycast extension underextensions/raycast/with seven no-view commands that invoke those deeplinks and provide HUD feedback.Main concern: the deeplink URL parsing/validation logic in
DeepLinkAction::try_fromappears inverted, causing validcap-desktop://action?...URLs to be treated asInvalid, which would prevent the Raycast commands (and any other deeplink client) from working at all.Minor follow-ups include making the Raycast “Cap installed” check consistent across commands, and avoiding non-reproducible
@latestusage in the extension’s publish script.Confidence Score: 2/5
DeepLinkAction::try_fromthat rejects validcap-desktop://actionURLs, which is core to the PR’s functionality. Other issues are smaller UX/reproducibility concerns.Important Files Changed
