It's hard to write a good developer documentation. Examples are easier to understand and to maintain. We will write a number of plugins, that each uses one feature of Piwik: - ExampleDBAccess - ExampleFeedburner - ExampleWidget - ExampleEditMenu - Other features to cover in example plugins: API, plotting data, recording new data in new db table, running tests, using a config file, using the "option" mechanism, etc.

Then we would: - build a wiki page listing all the Example plugins - print their quick description - link to their source code

Examples of other open source project plugin documentation * writing a plugin http://codex.wordpress.org/Writing_a_Plugin * plugin api http://codex.wordpress.org/Plugin_API * mediawiki plugin hooks http://www.mediawiki.org/wiki/Manual:Hooks

Ideas of simple useful plugins - "You have X websites and Y users registered in Piwik. You are using Piwik A.B version." - "Featured user" that randomly picks a use case from our use case base. - "Piwik has been downloaded N times."

Technical notes: * content loaded from piwik.org via highly cached proxy pages * if piwik.org is down, should not affect loading time of dashboard * have one widget for general purpose content (Piwik has been downloaded X times)

I added two new widgets in changeset 2958 - "You have X websites and Y users registered in Piwik. You are using Piwik A.B version." - "Piwik has been downloaded N times."

They demonstrate simple database queries and a remote API call to demo.piwik.org (via jquery ajax request). Both widgets use templates.

greg: You forgot to check in the en.php - both widgets appear but their translations are missing.

We should also have the documentation point to ExampleUI plugin

It would be nice to document how plugins can create new sections in the config file.

Something like this (but finding a way not to call the __destruct would be better)

$config = Zend_Registry::get('config');
$config->MobileAnalytics = array("TeraWurflURL"=>"unconfigured");
$config->__destruct();
Piwik::createConfigObject();

I'm not sure why it wasn't working before, but this works great now.
Result:

[MobileAnalytics]
TeraWurflURL = "unconfigured"

Agree. Planning a cleaner config writer should already be in #1713.

@mattab commented on November 24th 2010

Also, while writing dev doc, I recommend going through the config.ini.php settings to find out which ones could be of interest to the Piwik plugin developer (I'm thinking eg. disable_merged_assets, track_visits_inside_piwik_ui, always_archive_* etc.)

The new general layout of the documentation is now in place (piwik.org/docs).

Plugin guides are part of the new organization but are yet to be written. The proposed list is :

Development Guides Basic architecture Adding a widget Use Smarty templates Accessing the database Editing the menu Using Piwik's API Plotting Data Recording new Data Adding options in config.ini

@julienmoumne commented on March 4th 2011

Should include guide : Internationalization and localization See forum post

Mostly we have such simple plugins now. The docs are still missing but will be covered in separate plugin. For latest docs on plugin development see: http://new.piwik.org/docs/plugins/
