Notes on various text api projects

---

Enhancements that possibly require alternatives to standard Document classes:

• Chat rendering
  • Could possibly simply be sped up with ElementSpec[] insertion
  • May just need alternate view? formatting is derived from structure?
• SM: enhanced doc construction

Enhancements that may just need alternative View classes:

• Syntax highlighting for wiki-style text and raw html editor components
  • Should at least color-code shorthand elements and html tags
  • Could interpret bold, italic, and headline tags
  • Blue: start-of-line tags, correct link/embed tags, correct & sequences
  • Grey: terminated html tags
  • Red: Incorrect/unterminated link/embed tags, html tags, or escapes
• Paren highlighting in formula editor
• WYSIWYG editor
  • need attribute support in SharedDocument
• Spell checking?
  • See "Jazzy" on sourceforge/freshmeat
  • Word lists at http://wordlist.sourceforge.net/

API notes:

• AbstractDocument.createLeafElement(...) only called at EOL
• GlyphView.createFragment(...) is called on line/word-wrap
• GlyphPainter imp that wraps existing imp, intercepts calls, changes Graphics context color, and
  • Element responsible for tracking runs
  • RunSet cached, recomputed only if text changes
