I would like to distribute all the themes that are in the ThemeRoller gallery (as part of the jquery-ui-rails gem).
I noticed that you can download them using "build themes-download". However, this gets the themes from the ThemeRoller with version 1.8.17, not with whatever version I have checked out. This will cause some maintenance headache, I fear.
Is there a way (even a hack) to generate the theme files straight out of the repository?
There isn't currently a way to generate the themes just from the checked out files. Part of our current release process is to publish the to-release build on a dev instance of ThemeRoller (which is the only thing that can generate themes today) and point the build script at that server and automatically download and then unzip each theme folder :/.
The next version of our build script (that will support the next versions of the Download Builder and ThemeRoller) will support 100% headless generation of gallery as well as custom themes. This is already planned but not yet in development.
