2.3.4. Configuring Message Templates
In the Plugin Manager, select the Configuration tab to customize your message templates. You can add, edit or remove the key-value pairs. You can specify any number of key-value pairs.
In any template, the occurrence of every $key is replaced by the value it has in the configuration. For example, if you set the key to Manager and the value to Harry, any occurrence of $Manager is replaced by Harry in the message.
Assume that you have 1000 message templates with your current manager's name has a reference in them. When the current manager is replaced by a new one, it's not easy for you to manually replace the manager's name in all the 1000 messages. If the messages have a $Manager key value, you can reset the value in the Configuration tab of this plugin.
By default, the entire environment variables are used as a key-value pair. An occurrence of $env_variable is replaced by the value it carries. For example, an occurrence of $PATH in your template is replaced by its value when the template is used.
The replacement process uses the following order of precedence:
* $key is replaced by the value set for it in the Configuration tab of the Templates plugin.
* If the key is not found, it is then replaced with the value of its environment variable.
* If key is neither a configuration option nor an environment variable, no changes are made
