Maybe I'm just having an attack of premature senile dementia, but looking at the DB module documentation it looks like subclassing should be easy - something along the lines of:
package Devel::larryk;
use base qw(DB);
use strict;
Devel::larryk->new()->register(); # create instance and register
sub new { bless {} }
sub init {
my $self = shift;
$self->ready();
print "larryk initialised\n";
}
1;
This should then be invokable from the command line, as:
perl -d:larryk foo.pl
...but it doesn't work. Why?
Because as soon as I use the DB module (in order to subclass it) it immediately calls ->init() on all registered clients. But of course I haven't registered as a client yet because I only just used it. So I seem to have a chicken and egg situation.
How can this work?
larryk
perl -le "s,,reverse killer,e,y,rifle,lycra,,print"

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).
