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:

After Fix UI Screenshots

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?

Walkthrough

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

Full details: Title check

Explanation

The title uses the fix: prefix with the scope (create playlist), which matches the required conventional-commit format. It states the main change: the input boxes scroll and the cursor stays clamped on the name and search fields. The changeset adds horizontal scrolling to both Create Playlist inputs, so the title describes the main change.

Full details: Linked Issues check

Explanation

Issue #829 is the only directly linked issue. Its coding requirements are horizontal scrolling in both Create Playlist text inputs (playlist name and Add Tracks search), a cursor that stays inside each box, the helper and tests named in the issue, and no changes to the handlers or app.view.

The whole-PR diff of src/tui/ui/create_playlist.rs at head implements each requirement:

• input_scroll(cursor, box_width) subtracts the two border columns. It returns 0 when the inner width is 0 or the cursor fits. Otherwise it returns cursor - inner_width + 1. This matches the formula named in the issue.
• draw_name_stage and draw_add_tracks_stage compute offset from inner[1].width and inner[0].width. Each applies Paragraph::scroll((0, offset)). Each sets cursor x to inner.x + 1 + cursor - offset. The offset never exceeds the cursor, so the subtraction cannot underflow.
• Helper tests match the issue values: input_scroll(5, 20) == 0, input_scroll(5, 0) == 0, input_scroll(18, 20) == 1, input_scroll(40, 20) == 23.
• Both render tests use the names from the issue. They now assert exact cursor positions, which changed since the previous review. The name test asserts x == 86. Layout check: popup x=10 width 80, margin 2, box x=12 width 76, inner width 74, offset 127, cursor x = 13 + 200 - 127 = 86, and the right border is at x=87. The search test asserts x == 87. Layout check: box x=11 width 78, margin 1, inner width 76, offset 125, cursor x = 12 + 200 - 125 = 87, and the right border is at x=88. Both values lie inside the box, one column before the right border.
• src/tui/handlers/create_playlist.rs and app.view are not in the diff, as the issue requires.

The issue's manual narrow-terminal check is non-coding and is not assessed. The issue's example test sizes (50x20, 60 chars) differ from the implemented tests (100x30, 200 chars). The issue gives those sizes as a proposal, and the implemented tests still verify the required containment.

Full details: Out of Scope Changes check

Explanation

The whole-PR diff against the merge base touches two files.

• src/tui/ui/create_playlist.rs: the input_scroll helper, the scroll offset and cursor adjustment in the two input draw functions, and the four tests for that behavior. Every hunk supports #829.
• CHANGELOG.md: one added line under the Unreleased fixes. It describes the Create Playlist scroll fix and links #829. This is documentation of the same change.

The PR objectives mention a request to file a separate issue for grapheme-aware widths. That is a process item, not a code change, and no code for it appears in the diff. No unrelated code change was found.

- Line 68: Update the create-playlist input rendering path so both the offset
and cursor position use the rendered grapheme width of the text before their
respective editing indices, rather than character-count indices. Apply this to
the `input_scroll` call and the corresponding cursor-position calculation.

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.

[IDLinares]

Both render tests have been updated to assert the exact cursor instead of a range as requested. The create_playlist test suite was rerun, and all tests still pass.

Follow-up Comments

Assert that the scrolled suffix is rendered.

281-334: Trivial · Functional Correctness · Quick win

Assert that the scrolled suffix is rendered.

The long-input tests check only cursor coordinates. Use a distinct final character and assert that it appears immediately before the cursor in each input row. This makes the tests fail if paragraph scrolling is removed.

Suggested fix

-    app.view.create_playlist_name = "a".repeat(200).chars().collect();
+    app.view.create_playlist_name = ("a".repeat(199) + "z").chars().collect();
...
     assert_eq!(cursor.x, 86, "cursor x was {}", cursor.x);

Update `long_playlist_name_keeps_the_cursor_inside_the_input_box` and
`long_search_query_keeps_the_cursor_inside_the_search_box` to use a distinct
final character and assert it is rendered immediately before the cursor in each
input row. Keep the existing cursor-position assertions so the tests verify both
cursor placement and rendering of the scrolled suffix.
