How to pack a Magento extension

This admin page will help to pack your extensions, such as modules, add-ons, language packs, interfaces and themes, into PEAR packages which you could upload to MagentoConnect and share with other community members.

To start packing extensions, log in to Magento Admin panel and go to: Admin Panel: » System » Magento Connect » Package Extenssions.

You can easily follow the 5 step process to generate the extension that are described in the remaining article.

The extension packaging process includes generation of package.xml file with information about the package collected by the 5 steps below, and archiving content files and folders specified by the Contents step.

After package is uploaded to Magento Connect, it will be available for downloading and installation for other members, by pasting extension key into Magento Connect downloader.

Extension key is constructed from:

  • PEAR channel nickname (magento-core or magento-community)
  • Short package name (Mage_Core_Modules)
  • Numeric release version (1.2.3) or release stability (beta) – optional>

So the extension key could look like this:

  • magento-core/Mage_Core_Modules-1.2.3 – specific release version will be installed
  • magento-core/Mage_Core_Modules-beta – latest beta release will be installed
  • magento-core/Mage_Core_Modules – latest release for local stability settings will be installed

NOTES

Make sure that downloader/pearlib/php and var/pear folders exist and have writable permissions for the web service.

In version 1.0 you should run these commands before packaging extensions, to initialize PEAR packager:

Channel fields can be:

  • CORE packages: connect.magentocommerce.com/core (nickname magento-core)
  • COMMUNITY packages: connect.magentocommerce.com/community (nickname magento-community)

Any Suggestions on what to do in version 1.2?
