Summary

Typing a long playlist name in Create Playlist, or a long query in the Add Tracks search box of Create Playlist, ran the text past the right border, and the terminal cursor left the box with it. Both inputs now scroll horizontally, and the cursor stays at the right edge, matching the behavior of the main search bar.

Fixes #829

Changes in src/tui/ui/create_playlist.rs:

• Added input_scroll(cursor, box_width) private helper with formula from search bar in search.rs
• draw_name_stage and draw_add_tracks_stage pass offset to Paragraph::scroll((0, offset)) and subtract from cursor x position
• Added 4 tests: two for helper and two render tests that assert the cursor stays in the input field. They failed before and pass after the fix
• Updated CHANGELOG.md with a line about the fix

Additional notes

Manual check on Windows 11 10.0.26200 (x64), Git Bash terminal, and SpotatiUI version 0.47.0 was also done, and the screenshots below show the before and after. The name field scrolls, and the cursor stays at the right border:

Possible follow-up (not in this PR): the Create Playlist handlers track the cursor by summing c.width() per char. For multi-code-point emoji (e.g. joined sequences like 👩‍💻 or skin-tone emoji), that can differ from the width Ratatui draws, since it renders them as one grapheme. In the extreme case (dozens of joined emoji in one name) the scroll offset can exceed the rendered text and the box looks empty. This predates this PR and, as far as I can tell, applies to the main search bar too. Issue #829 says to leave the handlers alone, so I kept this PR to the scroll fix. Would you like a separate issue for grapheme-aware cursor widths in the input handlers?

Summary by CodeRabbit

• Bug Fixes
  • Long playlist names and searches in the Add Tracks field now scroll horizontally within their input boxes when the text exceeds the visible space. The cursor remains visible at the right edge as you type, making it easier to see and edit the latest characters without the input extending beyond its borders.

Walkthrough

The Create Playlist name and Add Tracks search inputs now scroll horizontally when text exceeds the visible width. Their cursor positions account for the scroll offset. Tests cover offset calculations and cursor placement.

Changes: Create Playlist input scrolling

Layer / File(s)	Summary
Calculate and apply input scrolling src/tui/ui/create_playlist.rs, CHANGELOG.md	A helper calculates the horizontal offset for bordered inputs. The playlist-name and search inputs use the offset for rendering and cursor placement. Tests cover fitting and zero-width inputs, offset values, and cursor placement for long text. The Unreleased changelog records the behavior.

Estimated code review effort: 2 (Simple) | ~10 minutes

Full details: Title check

Explanation

The title uses the conventional-commit prefix "fix" with the scope "create playlist", which matches the required format. It states the main change: the name and search inputs in the Create Playlist flow now scroll horizontally and keep the cursor clamped. The raw summary and objectives confirm this matches the changeset. The subject is concise, but it is not written in the imperative mood, and it is 83 characters long.

Full details: Linked Issues check

Explanation

Issue #829 requires horizontal scrolling in both Create Playlist text inputs (playlist name and Add Tracks search), so the cursor stays inside each box. The head diff of src/tui/ui/create_playlist.rs implements this:

• input_scroll(cursor, box_width) subtracts the two border columns and returns cursor - inner_width + 1 when the cursor does not fit. It returns 0 for a zero-width box. This matches the search.rs formula named in the issue.
• draw_name_stage and draw_add_tracks_stage compute the offset from inner[1].width and inner[0].width. Each applies Paragraph::scroll((0, offset)) and sets cursor x to inner.x + 1 + cursor - offset. The offset never exceeds the cursor, so the subtraction cannot underflow.
• Four tests exist with the names listed in the issue. Two unit tests cover the helper. Two TestBackend render tests (100x30, 200-character input) assert the cursor x lies strictly inside the input border. I checked the layout math: name box right border at x=87 and search box right border at x=88 on that backend. The render tests assert ranges, not the exact x values the issue suggests, but they still verify containment.
• src/tui/handlers/create_playlist.rs and app.view are unchanged, as the issue requires. The cursor stays a display width.
  The issue's manual narrow-terminal check is non-coding and is not reported. It does not affect this verdict.

Full details: Out of Scope Changes check

Explanation

The whole-PR changes, per the summary and the inspected diff, touch src/tui/ui/create_playlist.rs and CHANGELOG.md. Every change in create_playlist.rs supports #829: the input_scroll helper, the scroll offset and cursor adjustment in the two input draw functions, and the four tests for that behavior. The CHANGELOG.md entry (reported as +1/-0) documents the same fix and is legitimate documentation. I did not read the CHANGELOG.md diff directly, but the summary content is consistent with the fix. No unrelated code change was found in the inspected diff.

Could the two render tests assert the exact cursor x instead of a range? On 100x30 that is 86 for the name box and 87 for the search box, and an off-by-one in the offset would then fail.

[LargeModGames]

On the grapheme widths: yes, please open a separate issue for it, covering both the Create Playlist handlers and the main search bar. Use the bug report template, and keep it out of this PR.
