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.

Hi everyone,
I am starting to use Ragel and I do need some help from you guys. This
is main.rl ( http://pastebin.com/vbinzrYg ), a Ragel + C simple program
to parse numbers according to this grammar *[0-9]+ ( '.' [0-9]+ )?;* .
The problem is that I am not able to get success parsing of correct
inputs using it.
This is the way I compile it :
/ragel -F0 main.rl/
/gcc -ggdb main.c -o main/
This is how I execute the program :
/$./main input.txt /
/
/
And this is the result : (please note that in the line is where is
executed the /%write init/ and/%write exec /Ragel code)
/cs: 0/
/integer_first_final: 3/
/-----------/
/cs: 0/
/integer_first_final: 3/
/integer_error/
/Parsing "input.txt"... Failed!/
$cat input.txt
/1.1/
The CS variable is having an mysterious behavior. I would appreciate any
kind of help or guidance. Thanks.
Best,
Luis Martin Gil
