[EP-tech] Re: plugin_alias_map restrictions?

1- copy it to your local repository directory:
cp lib/defaultcfg/citations/eprint/screen.xml archives/<id>/cfg/citations/eprint/ 

2- make changes (needs to be valid XHTML)

3- restart apache or reload config

Sounds like an option - how would I override the screen citation?

OK right I think I had read your post a bit too quickly Andrew, sorry!

Not sure which version of EPrints you're using - on 3.3.12,
Screen::EPrint::render_title is driven mostly by:


my $title = $self->{processor}->{eprint}->render_citation( "screen" );


So why don't you just over-ride the "screen" citation and add the item
type there?

Hi Seb,

So, in an attempt to understand the workings of this, trying to replace
the render_title in the Screen::EPrint  object by defining a local
'Screen::LocalEprint' package containing a render_title method doesn't
work, because the Edit screen is essentially already defined as a child
of the original EPrint definition before the alias mapping takes effect?
So you need to replace/create the method in the specific class that is
being instantiated?  (I've probably just mashed up some OO terminology
quite badly there!)

Should look something like:

e.g. in
archives/<id>/cfg/plugins/EPrints/Plugin/Screen/EPrint/LocalEdit.pm

#code-start
package EPrints::Plugin::Screen::EPrint::LocalEdit;

@ISA = ( 'EPrints::Plugin::Screen::EPrint::Edit' );

use strict;

sub render_title
{
       # whatever you need to do
}

1;
#code-end


in the conf (e.g. archives/<id>/cfg/cfg.d/plugins.pl):

$c->{plugin_alias_map}->{"Screen::EPrint::Edit"} =
"Screen::EPrint::LocalEdit";
$c->{plugin_alias_map}->{"Screen::EPrint::LocalEdit"} = undef;


Then when EPrints calls Screen::EPrint::Edit, it will call your
LocalEdit plug-in instead, in a transparent manner.

Seb.

Hello! I¹ve been working with archive localised plugins but have come
up against one that¹s giving me grief. I¹m trying to extend
Screen::EPrint with the intent of overriding the render_title function,
adding the Eprint type to the output.

I¹ve gone through the motions of creating a new child plugin with all
the correct dependencies, adding the alias map line into plugins.pl,
however EPrints does not seem to be inheriting this plugin at all. Are
there limitations on what can be changed this way?
