Plugins
=======

Thruk is easily extenable with plugins and there are some plugins
already included. Plugins itself reside in the
'plugins/plugins-available' directory. Activate a plugin by creating a symlink
in the 'plugins/plugin-enabled' directory. If you use the packaged Thruk
version, the plugins folder is directly in your Thruk folder. If you are using
OMD, the plugins folder is in $OMD_ROOT/etc/thruk/plugins.
Make sure you restart Thruk / Apache after enabling / disabling
plugins.

NOTE: With Thruk 2.0 a few minor changes are required for plugins. If you
have own custom plugins, the link:thruk_2_0_migration_guide.html[Migration Guide] will
help you getting them to work with Thruk 2.0.

Later versions of Thruk have a plugins manager included in the config
tool and you can manage your plugins there.

Example of a plugins folder with some plugins enabled.

Hello World Plugin
~~~~~~~~~~~~~~~~~~

----
 Author:      Mikael Nordin
 Description: Hello World Plugin
 Download:    https://github.com/mickenordin/thruk_hello
----

The hello world plugin should get you started if you want to
write your own plugin.





Writing your own plugins
------------------------

The directory structure of a plugin is similar to a normal perl
module. The following example has lib, static content, templates and
tests. But you don't need all of them.

TIP: Let me know if you want to get your plugin listed here.

++++
<pre style="line-height:18px;">
  ├── lib
  │   └── Thruk
  │       └── Controller
  ├── root
  │   └── images
  ├── t
  └── templates
</pre>
++++

.Structure
* 'lib' containts all Perl files
* 'root' contains all static content
* 't' keep the tests here
* 'templates' contains all template files for dynamic pages

Hello World Plugin
~~~~~~~~~~~~~~~~~~
In this example we will create a small Plugin that displays the words
"Hello World!" on the plugin page hello.cgi.

First we create a minimal directory structure the plugin directory,
in linux it might be done like this:

++++
<pre style="line-height:18px;">
mkdir -p hello/{lib/Thruk/Controller,templates}
</pre>
++++

.Next we need to create some files:
- hello/description.txt
- hello/preview.png
- hello/routes
- hello/lib/Thruk/Controller/hello.pm
- hello/templates/hello.tt

.hello/description.txt
This file contains some basic information about your plugin displayed
on the plugin overview page. For example

++++
<pre style="line-height:18px;">
The 'Hello World' plugin displays the words "Hello World!" on the
plugin page hello.cgi.

Url: hello.cgi
</pre>
++++

.hello/preview.png
This is an image file that is also displayed on the plugin overview.

.hello/routes
This file is a snippet part of a perl module and contains a menu item
for the sidebar:

++++
<pre style="line-height:18px;">
##########################################################

=head2 add_routes

page: /thruk/cgi-bin/hello.cgi

=cut

$routes->{'/thruk/cgi-bin/hello.cgi'} = 'Thruk::Controller::hello::index';

# add new menu item
Thruk::Utils::Menu::insert_item('System', {
                                'href'  => '/thruk/cgi-bin/hello.cgi',
                                'name'  => 'Hello World!',
});
</pre>
++++

.hello/lib/Thruk/Controller/hello.pm
This file is a perl module and contains the actual perl code that is run.
In this case we only set a variable called hello_var in our Thruk::Context
that we will access from the template later:

++++
<pre style="line-height:18px;">
package Thruk::Controller::hello;

use strict;
use warnings;

=head1 NAME

Thruk::Controller::hello - Hello World!

=head1 DESCRIPTION

Hello World!.

=head1 METHODS

=cut


=head2 index

=cut

sub index {
        my ( $c ) = @_;

        return unless Thruk::Action::AddDefaults::add_defaults($c, Thruk::Constants::ADD_CACHED_DEFAULTS);

        $c->stash->{title}           = 'Hello World!';
        $c->stash->{'subtitle'}              = 'Hello World!';
        $c->stash->{'infoBoxTitle'}          = 'Hello World!';
        $c->stash->{template} = 'hello.tt';
        $c->stash->{hello_var} = 'Hello World!'; # This is our magic variable
}

1;
</pre>
++++
.hello/templates/hello.tt
This file is the template that builds our HTML for the hello.cgi page. It mostly
consists of HTML with some variables accessed via the [% variable_name %] notation.

[source,html]
----
<!DOCTYPE html>
<html>
	<head>
		<title>[% title_prefix %][% title %]</title>
		[% PROCESS _favicon.tt %]
		<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
		<meta name="viewport" content="width=device-width, initial-scale=1, maximum-scale=1, user-scalable=no" />
	</head>
	<body>
		<h1>[% hello_var %]</h1> <!-- This is where we access our variable -->
	</body>
</html>
----
Now if you want a more stylish plugin you can add some Thruk-common css and make your template look like this:
[source,html]
----
<!DOCTYPE html>
<html>
	<head>
		<title>[% title_prefix %][% title %]</title>
		[% PROCESS _favicon.tt %]
		<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
		<meta name="viewport" content="width=device-width, initial-scale=1, maximum-scale=1, user-scalable=no" />
		[% PROCESS _common_css.tt  %]
		[% PROCESS _header.tt
			css=["plugins/conf/conf.css"]
			js=["plugins/conf/conf.js"]
		%]
	</head>
	<body>
		<h1>[% hello_var %]</h1> <!-- This is where we access our variable -->
	</body>
</html>
----

You can also add some info boxes and your plugin will look like all the rest:

[source,html]
----
<!DOCTYPE html>
<html>
	<head>
		<title>[% title_prefix %][% title %]</title>
		[% PROCESS _favicon.tt %]
		<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
		<meta name="viewport" content="width=device-width, initial-scale=1, maximum-scale=1, user-scalable=no" />
		[% PROCESS _common_css.tt %]
		[% PROCESS _header.tt
			css=["plugins/conf/conf.css"]
			js=["plugins/conf/conf.js"]
		%]
	</head>
	<body>
		[% PROCESS _message.tt %]
		[% PROCESS _overdiv.tt %]
		[% PROCESS _infobox.tt %]
		<h1>[% hello_var %]</h1> <!-- This is where we access our variable -->
	</body>
</html>
----
You can also protect your cgi page using the authorization settings from cgi.cfg.

Lets say you want to limit access to users with both the permissions
'authorized_for_configuration_information' and 'authorized_for_system_commands'
then you can use the function '$c->check_user_roles' with the appropriate parameters to check permissions.
You can modify your index function in 'hello/lib/Thruk/Controller/hello.pm' to look like this
to stop anyone from accessing your cgi without proper permissions:

++++
<pre style="line-height:18px;">

sub index {
        my ( $c ) = @_;

        return unless Thruk::Action::AddDefaults::add_defaults($c, Thruk::Constants::ADD_CACHED_DEFAULTS);
        if( !$c->check_user_roles("authorized_for_configuration_information") || !$c->check_user_roles("authorized_for_system_commands")) {
                return $c->detach('/error/index/8');
        }

        $c->stash->{title}           = 'Hello World!';
        $c->stash->{'subtitle'}              = 'Hello World!';
        $c->stash->{'infoBoxTitle'}          = 'Hello World!';
        $c->stash->{template} = 'hello.tt';
        $c->stash->{hello_var} = 'Hello World!'; # This is our magic variable
}

</pre>
++++

That's it! With these files in place you can restart your webserver and you will have
a link to hello.cgi in your Thruk sidebar.

++++
<a title="hello" rel="lightbox[plugins]" href="plugins/hello1.png"><img src="plugins/hello1.png" alt="Hello World Plugin" width="30%" height="30%" /></a>
<br style="clear: both;">
++++

TIP: Try to copy an existing plugin, change it to your needs
or copy/paste ideas from it to your own.
