Re: Help with a regular expression for file name parsing

This works with the samples supplied:

print $data;;

#some "random stuff" @include "some file" did you parse that?
#more 'random' stuff @include 'another file' you sure?
#and more random stuff @include yet\ another\ file positive?

print for $data =~ m[\@include\s('[^']+'|"[^"]+"|.+?(?<!\\))\s]g;;
"some file"
'another file'
yet\ another\ file
[download]

Spreading that out a bit:

m[
  \@include \s       ## the introducer followed by a space
  (                  ## capture
      '[^']+'        ## A single quoted string with no embedded single
+ quotes
  |                  ## or
      "[^"]+"        ## a double quoted string with no embedded double
+ quotes
  |                  ## or
      .+? (?<!\\)    ## a min length string that ends in a space that 
+isn't escaped
  )
  \s
]gx;;

Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.

"Science is about questioning the status quo. Questioning authority".

In the absence of evidence, opinion is indistinguishable from prejudice.

The start of some sanity?

Your regular expression works, but the code is rather a muddle. Here's a version that he can use to test with: `$data = join '', <DATA>; print "$_\n" for $data =~ m[\@include\s('[^']+'\|"[^"]+"\|.+?(?<!\\))\s] +g; __DATA__ #some "random stuff" @include "some file" did you parse that? #more 'random' stuff @include 'another file' you sure? #and more random stuff @include yet\ another\ file positive?` [download]	[reply] [d/l]

When tested with this version, the output is just `1`	[reply] [d/l]

Are you sure you copied it correctly? I get this: `"some file" 'another file' yet\ another\ file` [download]	[reply] [d/l]
