Subject: regex.7.gz: The [[:<:]] and [[:>:]] word boundary regexps are not supported

Date: Thu, 17 Feb 2005 11:29:08 +0100

Package: manpages
Version: 2.01-1
Severity: minor
File: regex.7.gz


  Hello  !

  The regex.7.gz mentions that [[:>:]] and [[:<:]] are available to designate word boundaries. 
However, neither grep nor sed, which are build on the standard libc regcomp do recognise this syntax. 
Moreover, the small program here 

#include <regex.h>
#include <sys/types.h>
#include <iostream>

using namespace std;

int main()
{
  regex_t RE;
  int err_code = regcomp(&RE, "[[:<:]]",
			 REG_EXTENDED);
  char Buffer[100];
  if(err_code) {
    regerror(err_code, &RE, Buffer, 100);
    cerr << "Error : " << Buffer << endl;
  }
}


produces the following error message:

Error : Invalid character class name

My guess is that this feature is not implemented anymore, or has never been. Then, two solutions: 
either remove it from the documentation, or at least mention that it's not supported anymore - either 
put the feature back into libc ;-) !

  Thanks for considering this report

	Vincent Fourmond

Hi Michael,

looks like the manpage needs an adjustment, or at least a note when
the GNU libc is used.

Regards,

	Joey

Testing? What's that? If it compiles, it is good, if it boots up, it is perfect.

Please always Cc to me when replying to me on the lists.

Hi Joey,

What does "looks like" mean.  Did you research this, or just 
leave it to me? (I have limited time...) FWIW, as far as I can
tell (from reading the regcomp source), it looks like the 
man page is wrong. But it would assist in the future if you 
could have a shot at the leg work (if technically possible) 
on reports such as this. 

I have commented out that paragraph of the manual page,
and the change will appear in man-pages-2.03.

Cheers,

Michael
