Information for plugin contributors

Prerequisites

A working Docker 1.12+ and Docker Compose installation (https://docs.docker.com/installation/).
Composer (https://getcomposer.org/download/).
PhantomJS 2.1 or greater (http://phantomjs.org).
MySQL client and admin tools.

Running the plugin in WordPress

Run bin/run-wordpress <version>. E.g. bin/run-wordpress 60.
Connect to Wordpress on port 80<version> (e.g. port 8060).

Running the unit tests

Run bin/unit-tests <optional path to file>.

Running the integration tests

Install Docker 1.12 and docker-compose.
Run bin/integration-tests <version>. E.g. bin/integration-tests 60.

Check if the code follows WordPress standard

Run bin/check-style to make sure there are no errors.

Test XML-RPC code

WordPress can either be used via the web interface or through the official WordPress apps for mobile devices. WordPress uses XML-RPC internally to communicate between the app and the WordPress admin. Make sure therefore that when developing functionality that is linked to functionality available in the mobile app that it also works over XML-RPC.

Translating the plugin

Language packs will be generated for the plugin once translations for a language are 100% filled in and approved.

See https://translate.wordpress.org/projects/wp-plugins/tiny-compress-images.

For development you may create .po and .mo files for a each language. The .mo files can be created with gettext. Install gettext and generate the .mo language file do the following:

Install gettext for example run brew install gettext.
Add a link msgfmt ln -s /usr/local/Cellar/gettext/0.19.7/bin/msgfmt ~/.bin.
Generate the .mo files bin/format-language-files.

When finished modifying, you can upload the changes to the SVN trunk. Within roughly 15 minutes WordPress will be updated and allow to add missing translations before publishing the new plugin release.
