Create Update Package in EasyCreator

[ripper17]

Hi

First: This is an amazing component, saving so much work when developing a component. It is perfect for packing the installation file.
What would make this even more usefull would be the possibility to create an update package as well.

This is what I think would be needed:
- User Input: Select the old version (which is the base for the update)
- Automatic: Unzip this old version and run a DIFF on the old version compared to this version
- Automatic: Recognize which files have been added / edited
- Automatic: Recognize, if the SQL installation file has been changed, if so:
 - Automatic: Create an (or modify the existing) install.COMPNAME.php file that will be executed during the Joomla installation of the package to UPDATE the database.
- Automatic: Create the XML Update manifest (this just needs to hold an extra attribute compared to a "normal" manifest
- Automatic: ZIP and TAR.GZ the update package.

I know that this is a lot of work, but I think this would be immensly usefull!

Best regards

Martin

No news about this idea ?

I've finally found some time to create a first iteration of a script that will create an update package.
It is a perl script, and I think it should be possible to call it with shell-exec, but I did not have a chance to try this!!

What does this script require:

• XML::Simple module
• On Windows: UnxUtils (available at http://unxutils.sourceforge.net/
• On Windows: the folder 'usr\local\wbin' from UnxUtils in your PATH variable

What does this script expect as input:

• The ZIP file of the the old version (-o oldVersion.zip) in the same directory as the perl script!
• The ZIP file of the the new version (-n newVersion.zip) in the same directory as the perl script!

What does this script do:

• Check for changed files (including language files)
• Create a new upgrade manifest
• Zip it all together

What does this script not do (yet):

• Check for changed SQL install instructions
• Therefore it does not automatically create a new install.COMPNAME.php file

Maybe it's of use to some people or can even be integrated in EasyCreator (feel absolutely free to do so!)
I've attached the perl script for everyone to download and improve (*HINT*) :-)
