pyparsing - load ABNF?

Question

can pyparsing read ABNF from a file instead of having to define it in terms of python objects?

If not, is there something which can do similar (load an ABNF file into a parser object)

Answer 1

See this example submitted by Seo Sanghyeon, which reads EBNF and parses it (using pyparsing) to create a pyparsing parser.

Answer 2

There are lots of Python parsing packages: Python Parsing Tools. ANTLR in particular is very well-respected, and reads a grammar from a dedicated file.
