This was created to replace compass in a Rails project.

The generator supports multiple themes and the sprite dimensions are available in a dimensions.sass file as variables.

There are no other dependencies than Ruby and ImageMagick binaries (or compatible commands with convert and identify).

The image name contains an MD5 hash of all images content and is stored directly into public/assets
so that the resulting CSS doesn't depend on sprockets.

It took about 0.2s to generate two theme sprites for me with about 30 images each.

Simple script that should work if you follow the convention of declaring a single outer class per file with simple class names and structure.

Some files may not be compatible with refinements and should have some comment like "#skip-refinement-conversion" in the file header (first 10_000 chars of the file). The "class" line should also be in the header section of the file.

Files skipped will be copied "as is" to the new directory.
