Be able to output a minified file about myth

[mstade]

This sounds like it's out of scope of what Myth is trying to do. Myth takes the CSS syntax of tomorrow and compiles it into the syntax of today. Optimizing that code is probably best handled by a separate, focused tool to do just that.

hmm yeah, it seems out of scope for the node api itself. but since lots of the preprocessors (all?) include a way to minify to ease the workflow i could see that putting it in scope for the CLI

ah but then its in Rework already, so maybe just easier to make it in scope everywhere :)

I think you should do whatever lets you focus on the mission statement: providing future CSS syntax capabilities today. Maybe I'm being too much of a puritan here, but I reckon code optimization doesn't fall in to that bucket and is probably best handled by whatever tool fits that bill.

I agree: myth should focus on the mission statement. I personally prefer a "one app - one task approach", this enables me to use whatever css optimizer / linter / tool in my build process and switch them easily.

If you also add sourcemap support with the minification that would allow someone to see and edit the input.css in their browser's dev tools, instead of seeing just the output.css.

I also think minification should be left to a separate program. clean-css (for example) already plugs in quite nicely: cat input.css | myth | cleancss > output.css

[ianstormtaylor]

k yup, agreed. out of scope for myth, better to stay small and good at one thing. either use sqwish or clean-css

or minify if you want an easy-to-remember api for all of em :)

The curious thing here is that Myth is basically a packaging up of Rework with a fixed set of plug-ins, and as @ianstormtaylor mentioned, Rework supports compression, but this is obscured by the Myth CLI.

If you did want to use the Rework compression instead of cleancss or an alternative, you could use Myth indirectly as a Rework plugin instead of the CLI:
