− | This is the bits which you will need to get started...
| + | Core API modules. |
| + | * EPrint.pm |
| + | * DataObj.pm |
| + | * DataSet |
| + | * EPrint/EPrint |
| + | * EPrint/User |
| + | * EPrint/Subject |

− | A connection to the EPrints system is represented by an instance of [[API:EPrints/Session|EPrints::Session]]. The session object links to
| + | Todo later. |
− | * the [[API:EPrints/Repository#get_conf|configuration]] of the [[API:EPrints/Session#get_repository|repository]] (only one per session object, even if the system itself has multiple repositories). | + | * Paginate.pm |
− | * the [[API:EPrints/Session#get_database|database]] for the repository. | + | * Paginate/Columns.pm |
− | * the [[API:EPrints/Session#get_lang|language]] to output in. | + | * Box.pm |
− | And if a CGI script then also
| + | * Email.pm |
− | * the [[API:EPrints/Session#current_user|current user]], if any. | + | * Platform.pm |
− | * the [[API:EPrints/Session#get_request|apache request]]. | + | * Storage.pm |
− | | + | * TempDir.pm |
− | If you're writing your own script then you'll need to start by asking for a Session object.

− | == Command-line Script ==
| |
− | | |
− | #!/usr/bin/perl -w -I/opt/eprints3/perl-lib/
| |
− |
| |
− | use EPrints;
| |
− |
| |
− | use strict;
| |
− |
| |
− | my $archive_id = $ARGV[0];
| |
− | my $session = new EPrints::Session( 1, $archive_id );
| |
− | exit( 1 ) unless( defined $session );
| |
− |
| |
− | # do your stuff
| |
− |
| |
− | $session->terminate;
| |
− | | |
− | The "1" passed to Session tells it that we're a normal script and not a CGI script.
| |
− | | |
− | The $archive_id value is taken from $ARGV[0] which is the first parameter on the commandline. You could hard-wire the value if you wanted.
| |
− | | |
− | The use of "-w" to produce warnings and "use strict" to prevent sloppy code is just good Perl-practice.
| |
− | | |
− | == CGI Script ==
| |
− | | |
− | This is similar to a command line script but you don't need the path to perl and the archive_id is not needed as it will work that out from the web-request.
| |
− | | |
− | use EPrints;
| |
− | | |
− | use strict;
| |
− | | |
− | my $session = new EPrints::Session;
| |
− | exit( 0 ) unless( defined $session );
| |
− | | |
− | # do some stuff
| |
− | | |
− | # Return a result to browser (usually an HTML page)
| |
− |
| |
− | $session->terminate();
| |
− | | |
− | == Code in the EPrints Configuration Files ==
| |
− | | |
− | Such as eprint_render.pl or creating a new subroutine for render_single_value on a field.
| |
− | | |
− | These are always passed a $session so you don't need to create your own.
| |
− | | |
− | == Plugins ==
| |
− | | |
− | These are described in the section about plugins.
