Hi,
I have a perl regex to test if a file resides under a particular
directory. The test looks like this:
if ($filename =~ $directory) {
# yes, this filename resides under directory
}
This is working for most cases. However, it fails is the directory
contains a +. For example:
$filename = 'ports/www/privoxy+ipv6/files/patch-src::addrlist.c';
$directory = "^/?" . 'ports/www/privoxy+ipv6' . "/";
if ($filename =~ $directory) {
# yes, this filename resides under directory
}
Yes, I can escape the + in the directory name, but then I'd have to
test for all special regex characters and escape them too. That
sounds awfully complicated. ;)
I think it might just be easier to do a straight comparison of the
first N characters of the two strings where N = length of the
directory name.
Any suggestions?
thanks
