Re: regex needed with match operator

Here's a fix for your regex

if(m[/\w+/foo]) {
  s[.* /(\w+) /foo \z]($1)x;
  ...
}
[download]

Here's a simpler solution which grabs what is matched (as opposed to modifying the contents @FILES as your code does)

print m{ /(\w+) /foo\z }x, "\n"
  for @FILES;

See. perlre for more info on the regex used.

And once you try to store the retrieved bits, you arrive at something like `my @name; push @name, m{ /(\w+) /foo\z }x for @FILES;` [download] which, of course, is a map in disguise: `my @name = map m{ /(\w+) /foo\z }x, @FILES;` [download] Makeshifts last the longest.	[reply] [d/l] [select]

Thanks broquaint, Would you mind explaining exactly what the \z and x are doing in the regex? Thanks again	[reply]

Would you mind explaining exactly what the \z and x are doing in the regex? Sure, to quote the docs `\z Match only at end of string` This is very similar to `$` except `$` matches the end of a line or before a newline. `x Extend your pattern's legibility by permitting whitespace and comments.` As it says, it allows for more readable regex, which is generally desirable considering the acute succinctness of regular expressions.

Thank you, It makes a lot more sense now, and I didn't realize the differnece between $, and \z, but now I do.	[reply]
