Hi,

I want to make Alex to parse a file using states. I wrote a simple basic wrapped .x file but it complaints that it doesn't know the "begin" symbol. As listed here[1], my code does something like this:

<0> \/{2} { begin italic }

Am I doing something wrong? Should I manage myself the states? Should I use another parser generator?

Hi,

Just found out that only the monadic wrapper handles state. However, if I switch to it I receive the following error:

templates/wrappers.hs:133:15: Not in scope: `alexEOF'

Does anyone know what's going here? Thanks

Hi, Solved them after a night without sleep :) Thanks, -- Mihai
