Describes a single edit applied to a buffer's content.

Edit deltas are used for incremental content sync with the tree-sitter parser process. Instead of sending the entire file content after each change, the BEAM sends compact deltas that describe what changed and where. The parser applies these to its stored copy of the source and performs an incremental reparse.

Fields

• start_byte — byte offset where the edit begins
• old_end_byte — byte offset where the old (removed) text ends
• new_end_byte — byte offset where the new (inserted) text ends
• start_position — {line, col} at start_byte
• old_end_position — {line, col} at old_end_byte
• new_end_position — {line, col} at new_end_byte
• inserted_text — the text that was inserted (empty for pure deletions)
