 +====== Plugin Development ====== 
 +
 +It is very easy to write a DokuWiki plugin. Before writing your own, remember to search for similar plugins among [[:plugins|plugins already written]] and read through [[devel:security|security guidelines for plugin authors]].
 +
 +DokuWiki has a flexible plugin API which allows developers to extend its functionality, be it additional [[:wiki:syntax]] modes, custom [[action modes]], new [[:export]] formats, and a lot more. Depending on the plugin's purpose, a plugin can either consist of one, or more, components of the following plugin types.
 +
 +===== Plugin Types =====
 +
 +At the moment DokuWiki features seven different plugin types.
 +
 +  * [[Syntax Plugins]] extend DokuWiki's basic [[:wiki:syntax]].
 +  * [[Action Plugins]] can be used to extend or replace many aspects of DokuWiki's core operations, from saving wikipages to adding new [[action modes]].
 +  * [[Admin Plugins]] can provide administration functionality for DokuWiki - these plugins are accessible to superusers and managers via the Admin button.
 +  * [[Helper Plugins]] can be used to provide functionality to many other plugins, so each plugin doesn't have to re-implement a certain function over and over again.
 +  * [[Renderer Plugins]] allow to create new [[:export]] modes and to replace the standard DokuWiki XHTML renderer.
 +  * [[Remote Plugins]] allow to add webservices to your plugin.
 +  * [[Auth Plugins]] add additional authentication backend to the DokuWiki, which could be activated via configuration manager.
 +  * [[CLI Plugins]] add command line tools to your plugin
 +
 +A simple plugin like [[plugin:color|color plugin]] may only consist of a single file, ''syntax.php''. More advanced plugins consist of several components, for example the [[plugin:data|structured data plugin]] have the syntax handling split in "data entry" and "table view" components, an action component for the special edit button attached to every data entry and an admin interface for database maintenance.

 +===== Plugin Name =====
 +
 +A valid plugin name:
 +  * Should only contain the characters a-z and 0-9. 
 +  * Underscore is NOT allowed as:
 +    * This is used to separate ''<plugin name>'' from ''<component name>''
 +    * Using underscore will also give a [[:popularity|popularity]] rating of zero. 
 +  * If the same name is used by two different plugins
 +    * they are mutually excluding and inherently incompatible, 
 +    * furthermore only one of them can have a plugin homepage on dokuwiki.org.

 +
 +===== Publishing a Plugin on dokuwiki.org =====
 +
 +If you created a plugin, please share it with the community. Just create a page named after your plugin in the plugin namespace. E.g. if your pluginfolder is named ''sample'' create a page ''plugin:sample'' here in the wiki.
 +
 +The page should contain all needed documentation on how to install and use the plugin and give users a pretty good idea what it does before installing the plugin. Adding screenshots might be a good idea as well. When creating the new page, a namespace template will prefill sections and tips for you.
 +
 +At the top of the plugin page a few metadata fields have to be filled. A description of each field can be found on [[plugin:repository|Repository Plugin]] page.
 +
 +Users will see that an update is available in the extension manager. For this to work properly it is necessary that the date “Last updated on” at the Plugin wiki page equals the date in the file [[devel:plugin_info|plugin.info.txt]] in the source tarball/zipfile. If this is not the case, available  updates will not be shown or the “Update” signal will persist despite the plugin being up-to-date!
 +
 +Uploads are not allowed on dokuwiki.org, so you need to host your plugin files somewhere else. We recommend to manage your source with a Revision Control System like [[git]]. If you do, it's easiest to use a public repository host like [[https://github.com/|GitHub]], [[https://gitlab.com/|GitLab]] or [[https://bitbucket.org/|Bitbucket]] which offers also a bug tracker for your repository.
 +
 +Plugin developers can check the [[devel:badextensions|bad extension page]] for differences in their github repository checkin, the [[devel:plugin_info|plugin.info.txt]] and the respective page at dokuwiki.org.
 +
 +===== Inspiration =====
 +
 +Already more than 1200 plugins are written for DokuWiki. To learn how things are working, you might study some existing plugins that have some similarity with your ideas. At [[https://codesearch.dokuwiki.org/]] can find all them in a browsable format.
