Parsing text input with a LL(k)-parser
This is going to be the month of the weird ideas 
After writing all the stuff on product selection and recommendation, I’m now thinking about parsing form input with a LL(k)-parser (generated by JavaCC for example) to notice if people try to fill code into a form instead of “text content”. The idea came up my mind during a discussion with a client today and for me it seems to be interesting as I found some stuff tonight online and got a quite good plan how to implement it.
So, expect some more on grammars, finite state machines and regular expression during the next weeks
Curious what you come up with
