[asterisk-users] escaping regular expression

2009-02-04 Thread Klaus Darilion 
Hi!

I am going nuts using REGEXP. I just want to verify if a variable 
contains a valid +E164 phone number.

These, the the pattern is ^\+[0-9]+

First I tried:

   Set(pattern=^\+[0-9]+);
   if (${REGEX(${pattern} ${${var}})})

but that does not work, the backslash is removed, as seen in the log file:

   func_strings.c: FUNCTION REGEX (^+[0-9]+)(+4312345 
http://www.adaanumber.com/)

So, meanwhile I tried to escape the backslash. I tried:
   Set(pattern=^\\+[0-9]+);
   Set(pattern=^\\\+[0-9]+);
   Set(pattern=^+[0-9]+);

But always the same result:

   func_strings.c: FUNCTION REGEX (^+[0-9]+)(+4312345)

How can I solve this problem?

Thanks
Klaus

Try something like... pattern=^[+]\{1\}[0-9]+

Are you sure? The \ should be in front of the +

So, the \ is still stripped (ast_app_separate_args removes \), but, it
doesn't matter as the + is bracketed so it's not the first character after
the ^ and so regcomp doesn't fail...

Ah, the trick is to put the + into [], so it need not be escaped.
