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
