Re: save regex in a file?

If you really want to put the m and the delimiter in the file, you will have to remove them before applying the regex. Something like this:

$re =~ s/^m//;
$re =~ s/^.//;
$re =~ s/.$/;
$string =~ $re;

Note that this may not give the same behavior as a normal match if you've used a delimiter that also appears in the regex, e.g. m|foo\|bar|

It is a bummer to hear that. It really seems like a big disadvantage to not be able to specify the delimiter in the file as I know there are "special" delimiters that are sometimes used. It also means that I have to separately ask if there are any operators "ie: case insensitive" as an example...m/abc/i Would eval() help? I tried the simple case I could think of and it didn't seem to work... Thanks for ideas!!!	[reply]

Using eval would just introduces a whole new bag of worms; I don't think it would be the best solution. Fortunately, you can specify the modifiers within the regex. Here are two quick examples. `(?i)abc (?s-m:^start.*end)` [download] The first turns on case-insensitivity for the entire pattern. The seconds turn on single-line matching and turns off multi-line matching for the part of the pattern within the parentheses. perlre explains this syntax in more detail.	[reply] [d/l]
