Closes #456.

spotify-player CopyLink parity: cliamp share prints a shareable link for the current track (--copy also puts it on the clipboard), and Ctrl+Y does the same from the TUI with footer feedback. Daemon users get copy-from-anywhere without attaching.

Link derivation lives in playlist.ShareLink: Spotify URIs map to open.spotify.com pages (track/episode/album/playlist/artist/show, covered by unit tests), plain http(s) URLs pass through (YouTube Music uses full watch URLs in track paths, verified in external/ytmusic), and anything without a public page (local files, yt-dlp search expressions) reports no link. internal/clipboard resolves wl-copy/xclip/xsel/pbcopy/clip at call time with zero new dependencies.

Two choices I made that need maintainer sign-off:

  1. Key: y is lyrics, Y opens YouTube, so this takes Ctrl+Y (next to Ctrl+S save). Happy to leave it unbound or move it.
  2. Clipboard daemonizing: wl-copy/xclip fork to serve the selection, so the Copy path uses cmd.Run with discarded output — CombinedOutput hangs forever waiting on pipes the daemon holds. Caught live on NixOS/Wayland during testing.

Verified: go vet + go test ./playlist/ . ./ui/model/ clean, share/share --copy e2e against a live daemon playing Spotify (round-trips through wl-paste correctly).

Summary by CodeRabbit

  • New Features

    • Added a share command to print a shareable link for the currently playing track.
    • Added --copy to copy the link to the system clipboard.
    • Added Ctrl+Y to copy the currently playing track’s share link from the app.
    • Spotify links are converted to web links, while supported URLs are preserved.
  • Documentation

    • Documented the new CLI command and Ctrl+Y keybinding.
  • Bug Fixes

    • Added clear feedback when no track is playing or no shareable link is available.

Adds spotify-player CopyLink parity: a `cliamp share` IPC subcommand
that prints a shareable link for the current track (plus --copy for the
clipboard), and a Ctrl+Y client binding with in-app feedback.

playlist.ShareLink derives links from the track path: Spotify URIs map
to open.spotify.com pages (track/episode/album/playlist/artist/show),
plain http(s) URLs pass through, and anything without a public page
(local files, yt-dlp search expressions) reports no link. internal/
clipboard resolves wl-copy/xclip/xsel/pbcopy/clip at call time with no
new dependencies; callers fall back to showing the text.

y is taken by lyrics and Y opens the YouTube provider, hence Ctrl+Y
(right next to Ctrl+S save). No default-plain-key claim.

Closes bjarneo#456

📝 Walkthrough

Walkthrough

Adds share-link generation for supported track paths, cross-platform clipboard copying, a share CLI command, and a Ctrl+Y TUI action. Documentation covers both entry points and supported link behavior.

Changes

Track sharing

Layer / File(s) Summary
Share-link derivation and validation
playlist/sharelink.go, playlist/sharelink_test.go
ShareLink converts supported Spotify URIs and passes through HTTP(S) URLs. Tests cover valid and rejected paths.
Clipboard backend selection
internal/clipboard/clipboard.go, internal/clipboard/clipboard_test.go
clipboard.Copy selects platform- and session-specific clipboard backends, applies a five-second timeout per invocation, and reports unavailable or failed copies.
CLI and TUI sharing entrypoints
commands.go, ui/model/command_registry.go, ui/model/commands.go, ui/model/keys.go, ui/model/update.go, ui/model/share_test.go, docs/cli.md, docs/keybindings.md
The share command and Ctrl+Y action derive links, copy them when requested, and report results. Documentation describes both interfaces.

Priority: ➖ Normal

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: ⚪ Minimal · up to cf818

This change adds track-share links through the CLI and TUI, with supported Spotify identifiers converted to public URLs and clipboard failures reported clearly. No current merge-blocking risk remains.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

🔎 Supported by static analysis

🌐 Web query:

In the Go standard library documentation, does net/url.PathEscape escape URL path-segment delimiters such as "/", "?", and "#"?

💡 Result:

Yes, the Go standard library function net/url.PathEscape escapes URL path-segment delimiters such as the forward slash (/), as well as many other special characters, by replacing them with their corresponding %XX percent-encoded sequences [1][2][3]. Specifically, the official documentation states that PathEscape escapes a string so it can be safely placed inside a URL path segment, explicitly noting that it replaces special characters, including /, with %XX sequences [1][3]. Regarding the characters you asked about: - Forward slash (/): Yes, PathEscape converts this to %2F [1][4]. - Question mark (?): Yes, PathEscape is designed to escape special characters to ensure they do not interfere with the structure of the URL, and will escape the question mark to %3F to ensure it is treated as part of the path segment rather than the start of a query string. - Number sign (#): Yes, PathEscape will escape the number sign to %23 to ensure it is treated as part of the path segment rather than the start of a URL fragment. PathEscape is intended for individual path segments; if you have a full path with multiple segments separated by slashes, you should split the path and escape each segment individually rather than passing the entire path string into PathEscape, as it will escape all forward slashes [5].

Escape the Spotify identifier as one URL path segment.

ShareLink accepts id values containing /, ?, or # and inserts them directly into URL syntax. These characters can change the resulting path, query, or fragment. Use url.PathEscape(id) and add regression cases for reserved URL characters.

Proposed fix
-import "strings"
+import (
+	"net/url"
+	"strings"
+)

-			return "https://open.spotify.com/" + typ + "/" + id, true
+			return "https://open.spotify.com/" + typ + "/" + url.PathEscape(id), true

…ut, id escaping

- Print the link before reporting a --copy failure, and include it in
  the TUI footer fallback, so headless and clipboard-less setups keep
  the usable result.
- Bound clipboard backends with a 5s CommandContext deadline so a
  stalled backend cannot freeze the TUI update path.
- Reject Spotify ids containing reserved URL chars and PathEscape the
  rest, with a regression case. Add a no-backend clipboard test.

shareTrack returned only after clipboard.Copy finished, so a stalled
backend froze input and rendering for up to 5s per backend. Return a
tea.Cmd that copies in the background and report through shareCopiedMsg
instead, following the ytdlSavedMsg pattern. Success and failure footer
text unchanged. Adds Update-level tests for both outcomes.
