Token-oriented representation of program code with support for textual editing thereof

摘要: An editor, software engineering tool or collection of such tools may be configured to encode (or employ an encoding of) insertion point representation that identifies both a particular token token-oriented and character offset thereinto. Efficient implementations insert, remove replace operations are described herein. Computational costs typically scale at worst with the size fragments inserted into and/or removed from representation, rather than buffer size. Accordingly, particularly well-suited providing efficient support for programming environments in which stream is updated incrementally correspondence user edits.
