[BangPypers] python for parsing
Hello everyone , I am new to this community . recently i attended a python workshop in my college and got a lot mesmerised by the language so finally decided to port my mini project which i have partially written using LEX and Yacc into python. i would be glad if you could provide me some valuable suggestions on how to go about doing so. Thanking You Rahul ___ BangPypers mailing list BangPypers@python.org http://mail.python.org/mailman/listinfo/bangpypers

Thanks Dhananjay & Noufal , now i have tons of options. But then again i
am trying to find the most suitable one for my program.
Well basically what i am trying to achieve is to create my own syntax
(reasonably simple ) which will help the user to write simple HTML ( +CSS
hopefully) pages without actually coding any of it .
i.e for example
if the user writes
this is heading
--> { the '=' would be a token for headers }
the rest paragraph
the equivalent html generated could be
this is heading
the rest paragraph
besides i am also trying to incorporate inline CSS and other basic
functualities .

Hi, Rahul
It looks like you are trying to create an abstraction above the HTML+JS etc.
Have you looked at pyjamas pyjs.org ?
Though GWT uses java for the same thing.

Read the other code and learn from it, perhaps implement your own thing and compare it with the other to see if there are things to learn. Reinventing the wheel is usually pointless but as an educational experience, I think it's nice. -- ~noufal http://nibrahim.net.in ___ BangPypers mailing list BangPypers@python.org http://mail.python.org/mailman/listinfo/bangpypers
