====== Plugin Survey 2011 ======

Welcome to the third survey of all [[:plugins]] present in the plugin namespace of %%www.dokuwiki.org%%.
Data was collected by an automated script 2011-11-23 with some additional manual data download and mining. 
A total of 846 wiki pages containing 825 plugins was examined and source code for 802 plugins (97%) downloaded and parsed.

153 new plugins has been released since previous survey in September 2010 giving a growth figure of 23% a year.

Why?
  * To answer questions like "[[events|Who uses this Event?]]"
  * Monitor plugin developers response to changes like the new download button and new events
  * Give background to discussions about the plugin manager, meta data links, navigation & tags
  * Collect a ToDo list for [[wp>Wikipedia:Wikignome|WikiGnomes]] and some certain [[develtodo|developers]]
  * Just for the fun of it, if you like statistics, you know what I mean :-)

Find the answers in the survey
  * [[Deployment]] - Where and how do users find and install the plugins?
  * [[Compatibility]] - Are we up to date? Are [[syntax]] conflicting with other plugins?
  * [[Source code]] - Code metrics and which plugins have RTL CSS defined?
  * [[Events]] - List of found users for each event.
  * [[Friendliness]] - How well are the plugin system adopted to non-programmers?
  * [[Developers]] - How many have contributed to DokuWiki's wealth of plugins?

Some new highlights in the 2011 survey

  * [[friendliness#readability|Readability analysis]] of plugin homepages
  * Number of plugins [[source_code#jquery|using jQuery]]
  * [[source_code#php5|Usage of PHP5]]
  * [[events#deprecated_events|Deprecated events usage]]
  * List of plugins [[source_code#saving_data_on_action_save|saving data on action SAVE]]
  * Usage of the [[friendliness&#excluded_plugins|new securitywarning field]] in repository database
  * Graphs!

Enjoy!

===== Not every plugin is a plugin =====

What about the 21 other pages? IMHO some pages in the plugin namespace could not be considered plugins. All mentioned below beside [[plugin:div_span_shorthand]] were excluded from the plugin survey. Compared to last year, some pages have moved to more appropriate namnespaces and [[plugin:wysiwyg_nicedit]] plugin is now considered a real plugin.

**Manual page**
  * [[plugin:repository]] - This is the plugin for displaying the plugin list on %%www.dokuwiki.org%%. Page only contains a reference of how the database entry should be for each plugin home page. There is also a separate [[plugin:repository:manual|repo API description]] with a link to the source code.  

**Homemade redirect**
  * [[plugin:header]] - Points to [[plugin:numberedheadings]], database header used to collect/show popularity points?
  * [[plugin:html_comment]] (new) - Points to [[plugin:htmlcomment]]
  * [[plugin:rename]] - Points to [[plugin:pagemove]]
  * [[plugin:sioc]] - Points to [[plugin:dokusioc]]

**Deleted**

A plugin without database header is not visible in the main [[::plugins|plugin list]].
  * [[plugin:addnewpage_old]] - No database header for uncertain reasons.
  * [[plugin:category]] -  Intentionally removed, superseded by [[plugin:tag]].
  * [[plugin:coloured]] - No database header for uncertain reasons. Very similar to the [[devel:syntax_plugins|syntax plugin tutorial]].
  * [[plugin:definition_list]] - Intentionally removed, superseded by [[plugin:definitions]].
  * [[plugin:diskussion_forum]] - Work in progress, without code during 2006 -- 2010, still missing database header :-)
  * [[plugin:folding_sections]] - No database header for uncertain reasons.
  * [[plugin:larger]] -  Intentionally removed, superseded by [[plugin:bbcode]].
  * [[plugin:math_old]] -  Intentionally removed, superseded by [[plugin:math]].
  * [[plugin:pdfbook]] -  Intentionally removed, superseded by [[plugin:bookcreator]].
  * [[plugin:smaller]] -  Intentionally removed, superseded by [[plugin:bbcode]].
  * [[plugin:template_selector]] -  Intentionally removed, superseded by [[plugin:config]].

**Plugin twin**
  * [[plugin:div_span_shorthand]] - This page provides two related plugins: Span Shorthand and Div Shorthand. They were counted as one but code for both were examined during survey.

**Meta plugins** 

There is also a meta plugin system based on the [[plugin:command]] plugin. Some additional commands (class extensions) are published as plugins even though they could not be installed using the [[plugin:plugin|plugin manager]]. See this [[http://forum.dokuwiki.org/thread/3890 | forum post]] for an example of how another command is born.
  * [[plugin:date_time]]
  * [[plugin:freemind]]
  * [[plugin:gist]]
  * [[plugin:template]]

**Mods** 

While modifications found last year has moved to better places, now there is a new one ;-).
  * [[plugin:getraw]] - (new) Creates a url to get raw contents of a wiki, with authorization.

===== More plugins =====
Not all plugins are published at %%www.dokuwiki.org%% and these were __not__ included in the survey. Here are some examples:

  * [[http://rg42.org/wiki/dokuoauth_simple|OAuth]] - Implements basic oAuth support.
  * [[http://inetsoftware.de/other-products/dokuwiki-plugins/search-logger|search-logger]] - This plugin uses the search events to detect a search and store it in a database.
