[Catalyst] Displaying template files without adding new controller actions

If it's a TT file you need (i.e., not static), along with appropriate processing, you can make a variation on Ben's suggestion by using the $c->request->arguments, and putting the file name into $c->stash->{template} before handing off to the TT view, which is likely to be the default. This is a slight variation on ben's suggestion, which will only hit the file system when looking at the right part of the URI space. 

I've not tested this, but it'd just look something like:

sub dynamic : Local {
  my ($self, $c) = @_;
  my $args = $c->request->arguments();
  $c->stash->{template} = join('/', @$args);

This omits the error handling (assumes TT will take care of that) but should only handle requests that begin /dynamic. The arguments() method returns additional stuff after "/dynamic" in the requesting URL. 

I do something similar in my code (it's not precisely the same, as I retrieve the file contents through a model) and it works pretty well for us. 

For security, you probably want to remove stuff like "..", just to be safe. 

All the best

Like I said, you can either let the webserver serve up static pages. If you are worried about how the URL looks in the browser, some mod_rewrite magic will fix that for you, but that's a subject for another list :)
