parsing decimal numbers

[orangeduck]

Hey, you need to escape the period character . because it has the special meaning of matching any character in regular expressions (in this case it is matching a single space character).

You can try "number : /-?[0-9]+(\\.[0-9]*)?/ ; "

Thanks for bringing it up. I'll make sure to mention this in the book because a few people have had trouble with it.

Thanks! I tried to escape it, but with only one , I didn't try with a double \
Btw, your parser is very very nice software!

[orangeduck]

Yeah you need it twice because it is inside a C string, confusing!

Thanks :)

No... thanks to you.
I sent an email to [email protected] about "cons" :-)
When you have time if you can read it... thanks again!
