Module Bundles

How to create module bundles

When you want to bundle multiple modules into one single bundle, following would be the procedure to follow:-

• Package individual modules same as you do for any module manager compatible module.
• Put all such modules into one single directory.
• Place manifest.xml file in that directory in following format :

<?xml version='1.0' ?>
<module>
	<name>[Bundle Name]</name> 
	<version>[Bundle Version]</version>
	<dependencies>
		<vtiger_version>[Least Compatible Vtiger Version]</vtiger_version>
		<vtiger_max_version>[Most Compatible Vtiger Version]</vtiger_max_version>
	</dependencies> 
	<modulebundle>true</modulebundle>
	<modulelist>
		<dependent_module>
			<name>[Module Name - 1]</name>
			<install_sequence>[Sequence of the Module for Installation]</install_sequence> 
			<filepath>[Zip file name]</filepath> 
		</dependent_module>
		<dependent_module>
			<name>[Module Name - 1]</name>
			<install_sequence>[Sequence of the Module for Installation]</install_sequence> 
			<filepath>[Zip file name]</filepath> 
		</dependent_module><dependent_module>
			...
		</dependent_module>
	</modulelist>
</module> 

• Bundle this new directory similar to other module manager compatible directory.

Example:
