It makes no sense to let the user specify /g for a match. You can't even use it on qr// because it makes no sense. ixsm are the four modifiers that apply to the pattern as opposed to the operator.
-
The followign doesn't make much sense:
my $compd_pattern = eval "qr($pattern)" or die $@;
It removes the ability of qr// to quote, which is what you want. The code should be
my $compd_pattern = qr($pattern);
-
You say you have problems doing substitutions, but you didn't show us your attempt (despite your claim). You should have no problems using a qr// pattern in a substitution.
my $pat = ...;
my $repl = ...;
my $mods = '';
$mods .= 'i' if ...;
$mods .= 's' if ...;
$mods .= 'm' if ...;
$mods .= 'x' if ...;
my $re = qr/(?$mods:$pat)/;
if (...) {
s/$re/$repl/g;
} else {
s/$re/$repl/;
}

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
