📄 Description

Summary

This PR fixes the sparse spacing issue that occurs when displaying hyphenated words like 'claude-code-action' in both Assistant and User messages in the TUI. Fixes #621.

Problem

Previously, hyphenated words would break at hyphens, creating sparse single-word lines that made the chat interface look broken and difficult to read.

Before:

Solution

After:
image

  • Assistant messages: Use non-breaking hyphens (U+2011) in markdown rendering to prevent word breaks at hyphens
  • User messages: Apply non-breaking hyphens before word wrapping and styling
  • Textarea component: Modified word boundary detection to treat hyphens as part of words
  • Width constraint: Maintained 86 character width limit with precise calculations

Changes Made

  1. packages/tui/internal/components/chat/message.go: Updated user message rendering to use non-breaking hyphens
  2. packages/tui/internal/components/textarea/textarea.go: Modified word boundary detection in textarea word wrapping
  3. packages/tui/internal/util/file.go: Enhanced markdown rendering with hyphen handling

Testing

  • Verified both Assistant and User messages display correctly
  • Confirmed 86 character width constraint is maintained
  • Tested with various hyphenated words and phrases
  • No visual regressions in existing functionality

This change significantly improves the readability of hyphenated content in the TUI without affecting any other functionality.
