This is a port of the glibc gnu regex engine into perl. There are few
|
||
|
|
reasons you would need this. The few I can think of include:
|
||
|
|
|
||
|
|
0) You wish to use untrusted user expressions in such a way as to be
|
||
|
|
able to catch errors. Example: eval { alarm 2; m/((){1024}){1024}/ }
|
||
|
|
is an instant uncatchable segmentation fault. GNU's regexps will still
|
||
|
|
fail, but in a timeout way rather than an instant segfault way.
|
||
|
|
|
||
|
|
1) You wish to have POSIX compliance on ... something ... Perl's
|
||
|
|
regexps are slightly different -- arguably better, but different.
