- Description:
- PyBison is a Python binding to the Bison (yacc) and Flex (lex)
parser-generator utilities.
It allows parsers to be quickly and easily developed as Python class
declarations, and for these parsers to take advantage of the fast and
powerful C-based Bison/Flex.
Users write a subclass of a basic Parser object, containing a set of methods
and attributes specifying the grammar and lexical analysis rules, and taking
callbacks for providing parser input, and receiving parser target events.
Features
* Runs at near the speed of C-based parsers, due to direct hooks into
bison-generated C code
* Full LALR(1) grammar support
* Includes a utility to convert your legacy grammar (.y) and scanner (.l)
scripts into python modules compatible with PyBison
* Easy to understand - the walkthrough and the examples will have you
writing your own parsers in minutes
* Comfortable and intuitive callback mechanisms
* Can export parse tree to XML with a simple method call
* Can reconstitute a parse tree from XML
