Method and apparatus for program development using a grammar-sensitive editor

摘要

Techniques used in program development using a grammar sensitive editor are described. Input within an edit buffer is processed by a lexical and syntax analyzer in response to various syntactic and lexical states. Actions such as updating various multimedia indices are performed. Users are guided through program development through prompts for menu selection. The items transmitted on the menu are in accordance with the current state of lexical and syntactic processing. If an input in the edit buffer is invalid, the erroneous text is detected via the lexical and syntax analyzers and the erroneous text is highlighted. Additionally, transmitted via the menu is a selection of correct and valid alternatives from which the user may select to be included in the edit buffer.
