I implemented a Google Wave Robot which annotates BNF syntax rules using railroad diagram images. I put notes about the implementation process here for the benefit of posterity.
http://listtree.appspot.com/firstWaveRobot The robot Id is whiff-gae-tutor...@appspot.com -- if you are using wave, please add it to a wave and try it out. It should "respond" to a BNF rule you type in like this one: program ::= "begin" (statement ";")+ "end" $$ Happy Holidays everyone... I'm off to the slopes :). -- Aaron Watters === an apple every 8 hours will keep 3 doctors away --kliban -- http://mail.python.org/mailman/listinfo/python-list
