NAME

EPrints - Institutional Repository software


SYNOPSIS

use EPrints qw();

# don't check current user (CLI only)
use EPrints qw( no_check_user );

$eprints = EPrints->new;

# CLI
$repo = $eprints->repository( "demoprints" );

# CGI
$repo = $eprints->current_repository;

if( EPrints->VERSION() gt v3.2.0 )
{
	...
}


DESCRIPTION

See http://www.eprints.org/.


Available Symbols

You can pass options to the EPrints package that effect the EPrints initialisation e.g.

  use EPrints qw( no_check_user );
  • no_check_user
Do not check the current user/group is the same as the user/group in SystemSettings.


Debugging

To get a full stack trace on errors and warnings use Carp's verbose mode. E.g. in perl_lib/EPrints/SystemSettings.pm add:

  use Carp 'verbose';


METHODS

VERSION

$version = EPrints->VERSION()

Returns the version of EPrints in 'v' format (this is the UNIVERSAL method).


human_version

EPrints->human_version()

Returns the EPrints version in a human-readable form.


abort

EPrints->abort( $errmsg )

This subroutine is loaded before other modules so that it may be used to report errors when initialising modules.

When running under Mod_Perl this method is replaced.


dump

EPrints->dump( $VAR1 [, $VAR2 ... ] )

Use Data::Dumper to dump the passed variables to STDERR.


new

$ep = EPrints->new();

Construct a new EPrints system object.


repository

$repo = $ep->repository( $repository_id, [%options] );

Return the EPrints::Repository with the given ID, or undef. Options are... optional.

Options noise=>1, etc.


current_repository

$repo = $ep->current_repository();

Returns the current EPrints::Repository. The current repository is determined by the apache request.
