Development

Coding style

This repository follows a custom coding style, which can be validated anytime using the repository's provided configuration file.

Setup of the development environment

To get started, make sure you have a working set of the following components:

• gromox-http
• gromox-zcore
• php-mapi
• nginx

Checkout the repository into a new directory, e.g. /usr/share/grommunio-web-dev.

If you want to use the existing grommunio-web config, point config.php to it:

ln -s /etc/grommunio-web/config.php /usr/share/grommunio-web-dev/config.php

or use the config.php.dist file:

cp -p /usr/share/grommunio-web-dev/config.php.dist /usr/share/grommunio-web-dev/config.php

If you want to use the existing grommunio-web defaults, copy the defaults.php file:

cp -p /usr/share/grommunio-web/defaults.php /usr/share/grommunio-web-dev/defaults.php

Make sure to adjust /usr/share/grommunio-web-dev/defaults.php to use sources instead of the release variant as follows: Search for…

if (!defined('DEBUG_LOADER')) define('DEBUG_LOADER', LOAD_RELEASE);

and replace it with

if (!defined('DEBUG_LOADER')) define('DEBUG_LOADER', LOAD_SOURCE);

For debugging purposes it might make sense to enable debug.php file:

cp -p /usr/share/grommunio-web-dev/debug.php.dist /usr/share/grommunio-web-dev/debug.php

At last, adjust (or copy) the nginx config file /usr/share/grommunio-common/nginx/locations.d/grommunio-web.conf by replacing

alias /usr/share/grommunio-web/;

with

alias /usr/share/grommunio-web-dev/;

After changing the configuration, validate your nginx configuration with the nginx -t command and reload with systemctl reload nginx.

Translations

For performance reasons, the languages are loaded into the shared memory of the running system. After changes to the translation files, re-generate the gettext strings (see Makefile) and make sure you clear the shared memory segment for the cache:

ipcrm -M 0x950412de

The translations are managed through a Weblate project. Contributions are regularly monitored and integrated in the release cycles of grommunio Web.
