title: CatalystX::Dispatcher::AsGraph
summary: In which I wrote a module to visualize routes in Catalyst.
---

This morning I saw [this post](http://marcus.nordaaker.com/2009/05/awesome-route-graph-with-mojoxroutesasgraph/) from Marcus Ramberg about [MojoX::Routes::AsGraph](http://search.cpan.org/perldoc?MojoX::Routes::AsGraph). I liked the idea. But as I Catalyst instead of Mojo, I thought I could give a try and do the same thing for Catalyst dispatcher, and I've coded CatalystX::Dispatcher::AsGraph. For the moment only private actions are graphed.

You use it like this: `perl bin/catalyst_graph_dispatcher.pl --appname Arkham --output routes.png`

You can create a simple script to output as text if you prefer:

{% highlight perl %}
#!/usr/bin/perl -w
use strict;
use CatalystX::Dispatcher::AsGraph;

my $graph = CatalystX::Dispatcher::AsGraph->new_with_options();
$graph->run;
print $graph->graph->as_txt;
{% endhighlight %}

The code is on [GitHub](http://github.com/franckcuny/CatalystX--Dispatcher--AsGraph/tree/master) for the moment.

For thoses who are interested by visualization, I'll publish soon some (at least I think) really nice visualisations about CPAN, Perl, and his community, that we have created at [$work](http://rtgi.fr).
