Hi!
$c is hash reference with key "can_request_view_document";
The value for that key is anonymous sub.
You can call this sub like this
$c->{can_request_view_document}->($doc, $r);

Afternoon all,
I have been asked to take a look at a .pl file which is part of a
set-up called "EPrints". The particular file controls who can access
documents on a server.
Excluding some comments, the file starts like:
$c->{can_request_view_document} = sub
{
my( $doc, $r ) = @_;
It then goes on to complete the subroutine and return a value.
I understand that $doc and $r are populated via @_ but I have never
before seen the structure of the first line starting with "$c".
Additionally, the file doesn't look like a typical Perl file
(eg.#!/usr/bin/perl -w at the top and some use statements).
I know it's very vague, but could anybody explain this syntax to me?
My suspicion is that something else is calling the subroutines in this
file? Am I at least on the right track?
Thanks,
James
