Add inline sourcemap support

Some users want to use sourcemaps in development without creating any additional files, or even entirely over stdin/stdout. We should add an additional sourcemap type (in-css? base64? super-inline?) that does this.

Edited by @nex3 to retarget the issue. Previous report below:

I can’t find any possibility to get the sourcemap without having to write both, the compiled .css and the sourcemap file to disk.

I am looking for something like:

$ sass --sourcemap-only style.scss

which would output the sourcemap instead of the compiled .css.

This is relevant when writing transformers in certain frameworks since they only work in memory.

Precisely. sass is a command-line application, and as such it should be able to work with stdin and stdout as nearly any other command-line application does. Even programs that output binary files (like zip) do output the result in stdout. Actually… I can’t think of many scripts (apart from sass) that aren’t able to do that.

EDIT: Sorry. That may have come off a bit presumptuous. If you don’t want to implement my request, it’s obviously your choice and I’ll find a workaround. It being a command-line application is the reason I’d love that feature though. It will allow me to use it as I’d love using it, instead of having to implement a hack for it.

I’m moving this issue to the new Ruby Sass repository because it’s specific to Ruby Sass’s implementation. Once it’s there, I’m going to close it as “on ice” because Ruby Sass is deprecated and no additional features are planned for it.
