If you're willing to stick with backspace and carriage return, this really isn't a hard hack at all. Here's a twirly-bob:
{
my $p=0;
$|=1;
sub tick {
print substr(qq{|/-\\|/-\\}, $p++, 1), "\b";
$p=0 if ($p > 8);
}
}
Just call tick repeatedly and the thing will spin. Or a percentage meter:
{
my $bar=qq{0%..........50%..........100%};
$|=1;
sub bar {
local $_=$bar;
substr($_, $_[0]/100*length($_), 1)="|";
print "$_\r";
}
}
Just call bar with a number between 1 and 100 to indicate how complete things are.

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).
