feat(mobile): add #channel autocomplete to compose bar#411
Merged
Conversation
Add channel name autocomplete to the mobile chat input, mirroring desktop's #channel link feature. When users type # at a word boundary, a filtered suggestion list of non-DM channels appears (up to 8 results, case-insensitive substring match). Selecting a channel inserts #channel-name with a trailing space. - Detect # trigger via backward cursor walk with word-boundary check - Mutual exclusion with existing @mention autocomplete - _ChannelSuggestions widget with stream/forum type icons and labels - # toolbar button for manual trigger (alongside existing @ button) - Shared helpers: _findTrigger, _spliceAndMoveCursor, _insertTriggerAtCursor Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
…gger The refactored _findTrigger helper incorrectly stopped at spaces for all triggers, breaking multi-word @mention queries like "@alice Smith". Now accepts a stopAtSpace parameter: false for @ (only newlines stop the walk), true for # (spaces and newlines, since channel names are kebab-case). Also adds unit tests for findTrigger, filterChannels, and spliceAndMoveCursor. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
The channel detail page test expected exactly one hash icon, but the new compose bar toolbar adds a second one. Relax to findsAtLeastNWidgets. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
