feat(widgets): add duplicate remover widget - #42
Merged

Conversation
Turns a pasted list into a set: splits on lines, commas or whitespace, with optional trimming and case folding, and rejoins the unique values in first-seen, alphabetical or by-count order. A second tab lists each repeated value with how many times it occurred. The counts are free: deduplicating already needs a Map keyed on each value, so counting occurrences is the same pass (measured at 1M items, 790ms with counts against 621ms for a Set that discards them). What does not scale is rendering one row per duplicated value, so the summary lists the 200 most repeated and reports the rest as a total, and the input is read through useDeferredValue so a large paste never blocks typing.

- Line 125: Update the “Use as input” click handling around setInput so the
action is disabled or ignored whenever stale is true, preventing stale output
from replacing the current widget input; preserve the existing behavior when
stale is false.

- Keep untrimmed comma values as they are. With trimming off the items still carry the space that followed each comma, and joining them back with ", " grew every value by one space, so feeding the result back through "Use as input" changed the data. The separator now follows the trim setting, and a round-trip test covers it. - Disable "Use as input" while the result is stale. `output` is derived from the deferred input, so clicking during the deferred pass on a large list wrote the previous result over the edit that was still being processed. The handler is guarded as well as the button. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01K2aiBGNxfoFs9oBpSVBTsE

Turns a pasted list into a set, and shows which items repeated and how many times.

What it does
item2precedesitem10) or by-count order.Use as inputfeeds the deduplicated list back into the box.On large lists, and why the per-item counts are free
Deduplicating already needs a Map keyed on each value, so counting occurrences is the same pass. Measured in Node on this branch:
Setonly, no countsThe ~25% is one object allocated per distinct value, not a second pass. What does not scale is rendering one row per duplicated value: in Chromium, building and laying out raw list rows costs 25 ms at 1,000 rows, 239 ms at 10,000 and 2,509 ms at 100,000, before React's own overhead.
So the counts stay exact and complete, and only the list is capped, at the 200 most repeated values with the remainder reported as a total ("Showing the 200 most repeated of 120,000 duplicated values"). The input is read through
useDeferredValueso a large paste never blocks typing.At that scale the limit is no longer this widget but the
<textarea>itself: one keystroke in a bare 300,000-line textarea costs Chromium ~2.9 s (~1.1 s at 100,000 lines). Pasting a huge list is fine; editing it character by character is not, and that is true of every textarea-based widget here. Moving the input toCodeEditor(CodeMirror virtualizes) would be the follow-up if that ever becomes a real use case.Testing
npx tsc -b --noEmit,npm run lint(only the two pre-existingPageColorPicker.tsxwarnings),npm test: 967 passing, including 20 new tests on the pure engine and 10 on the widget (the 200-row cap and option persistence among them).🤖 Generated with Claude Code
