• Custom line iterator code for file loading, because rust's built-in one only recognizes LF and CRLF.

• Line number display

• Line wrapping

• File opening by entering path

• UI that wraps editors, for split view.

• Persistent infinite undo

• Multiple cursors

• "Projects"

• Move undo/redo functionality into Editor instead of Buffer

• Clean up text buffer interface:

  • //Editing (these are undoable):
    • //insert_text
    • //remove_text_before
    • //remove_text_after
    • //move_text
  • Undo functionality:
    • //Undo
    • //Redo
    • Edit transactions (for composite edit operations)
  • Info:
    • byte_count
    • //grapheme_count
    • //line_count
  • Position conversions:
    • //index -> line_col
    • //line_col -> index
    • //index -> vis_2d
    • //vis_2d -> index
    • index -> byte_index
    • byte_index -> index
  • Reading text:
    • //grapheme at index (includes visual width in return)
    • //Grapheme iterator (useful for search code, etc.)
    • Byte iterator (useful for search code, etc.)
    • Reverse byte iterator (useful for search code, etc.)
    • //Line iterator (useful for display code)
