Scannerless Generalized LR

Scannerless parsing is a parsing technique in which lexical and context-free syntax are integrated into one grammar and are all handled by a single context-free analysis phase. This approach has a number of advantages including discarding of the scanner and lexical disambiguation by means of the context in which a lexical token occurs.

Implementations

• SGLR is a Scannerless Generalized LR parser
• DParser is Scannerless Generalized LR parser generator.
