Redmine

h1. Plugins

Redmine plugins rely on "Rails engines" to add functionalities to the application.

h2. Plugin list

A full list of available Redmine plugins can be found at the "Plugin Directory":/plugins.

More plugins (some in very early development), which are not listed at the "Plugin Directory":/plugins but are publicly available on "GitHub":http://www.github.org, can be found using a "search like this":http://github.com/search?type=Repositories&language=&q=redmine&repo=&langOverride=&x=0&y=0&start_value=1.

h2. Installing a plugin

1. Copy your plugin directory into @#{RAILS_ROOT}/vendor/plugins@. If you are downloading the plugin directly from GitHub, you can do so by changing into your plugin directory and issuing a command like @git clone git://github.com/user_name/name_of_the_plugin.git@.

2. If the plugin requires a migration, run the following command to upgrade your database (make a db backup before):

  rake db:migrate_plugins RAILS_ENV=production

3. Restart Redmine

You should now be able to see the plugin list in _Administration -> Plugins_ and configure the newly installed plugin (if the plugin requires to be configured).

h2. Uninstalling a plugin

1. If the plugin required a migration, run the following command to downgrade your database (make a db backup before):

  rake db:migrate:plugin NAME=plugin_name VERSION=0 RAILS_ENV=production

2. Remove your plugin from @#{RAILS_ROOT}/vendor/plugins@.

3. Restart Redmine

h2. Writing plugins

There is a step-by-step [[Plugin_Tutorial|tutorial]] about writing a plugin. Some more (detailed) information is collected and stored in the "[[Plugin_Internals|plugin internals]]" page.

More (general) developer information can be found in the [[Guide#Developer-guide|Redmine Developer Guide]].
