[ragel-users] Basic Ragel parser - CS variable not changing

[Adrian Thurston]

Hi Luis,

I don't see the exact input file ... but my guess is that it includes a 
newline? Note that ragel always parses *exactly* the grammar that you 
give it. It does not scan forward looking for a match or disregard 
trailing data.
