Known Issues and Warnings for led Editor

Status Update (2026-03-20)

All major functions are operational with enhanced stability:

  • Search & Replace: Fully functional with improved regex handling and safety checks ✓
  • Syntax Highlighting: Multi-line nested blocks now correctly colorized ✓
  • Status Bar: Optimized and overflow-protected ✓
  • Test Suite: Expanded to 95 tests covering edge cases, large files, and word wrap scenarios ✓

Critical Warnings

  • Large Files: Files over 30000 lines hog the system and will need to process terminated.
  • File Validation: Rejects files >10MB or with null bytes to avoid crashes. Check file properties if loading fails.
  • Display Robustness: Very long lines (>10,000 chars) use basic rendering without highlighting for performance.

Limitations

  • Language Support: Optimized for C/C++; other languages may have incomplete highlighting or parsing.
  • Performance: Dense or very large files may load slowly; consider splitting files for better experience.
  • Word Wrap: Temporarily disabled due to cursor positioning bugs in word wrap mode. Will be re-enabled once fully fixed.

Workarounds

  • For large files, use external tools to split before editing.
  • Toggle off syntax highlighting in config for problematic files.
  • Run tests with ./led -t to verify stability on your system.
