Shifter - Blazingly Fast YUI Builder

The purpose of this project is to replace YUI's use of our old ant

We have out grown our old builder, so it was time to build a new one!


Shifter will parse your current *.properties files and convert them into a build.json file that it can process. It only imports the relevant settings required to build the module.

It does not import module meta-data

Instead, Shifter parses the meta-data from the modules meta/*.json files and uses that instead. So you don't have to declare your meta-data in more than one place now.


Shifter is designed to work side by side with our current builder (for now) so you don't have to switch over to using it fully if it doesn't work properly for you. Just don't delete your *.properties files until you are sure that Shifter builds your module properly. If it doesn't, file a ticket and we'll get it fixed up ASAP.

Shifter will read a build.json file if it exists, if one doesn't and it finds a *.properties file it will generate the build.json from them. So if you have issues with the build, just delete the build.json file and have Shifter regenerate it after your issue is fixed.
