I prefer
sub printlog {
print LOG @_ unless $nolog;
}
printlog "======== done =========\n";
to
print LOG "======== done =========\n" unless $nolog;
as it makes for less clutter. It is also beneficial in
that, with a little more work, $nolog doesn't
have to pollute the namespace.
BEGIN {
my $nolog = 0;
sub setlog {
$nolog = shift;
}
sub printlog {
print LOG @_ unless $nolog;
}
}
setlog 1;
printlog "======== done =========\n";
I like to generalise this functionality to handle debug/production screen output and/or
log file output.

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).

Want more info? How to link
or How to display code and escape characters
are good places to start.
