The openstack dashboard uses scss for styling, and so far we have used a python scss library for compiling those files to css for use in the browser. However, that library (pyscss) had in recent years some problems, and is not developed or supported by the authors anymore. So it's time to switch to something with a better support.
The django-compressor plugin that we use for handling the compilation of files allows us to use any command-line tool to do the compilation, so we can switch to an scss compiler that is supported and used by the wider community. However, there are several options we can choose from:
sassc
python-libsass
pysassc
ruby-sass
ruby-sassc
node-node-sass
Each of those would introduce a non-python dependency on the dashboard.
The question for the packagers and distro maintainer is which of those tools would be preferable in terms of support, packaging, and maintenance for the long term? Do you have opinions? Maybe there is another tool that would be even better that I didn't find?
