Dave, Not much hacking is required, really. I cooked up a simple function (taken from shards of yacc.yacc) pasted here: http://pastebin.com/m45b11057 It gets the same input module as yacc.yacc and just creates the Grammar object and returns it. The innards of Grammar are well documented and simple to use. Not sure how this can be hacked into PLY nicely, though. yacc.yacc tries to load the table from a precomputed file before it generates the Grammar itself - the Grammar isn't stored. Perhaps a separate function is the best approach, granted that the internals of PLY don't change. They will, of course, so perhaps it can be exposed more consistently as an API.
