Add ability to ignore specific directories or files

[neolefty]

Useful for a large project with multiple targets. For example, we have multiple "brands" which all get built from the same codebase. It takes about 5 seconds to build each one. But during development, I typically only care about one of them, so I'd like to ignore the rest.

I can do that with --update:

$ sass --update brands/my_brand

My current solution is to prepend _ to the other brands' main .scss files: rename brands/foo/foo_branding.scss to brands/foo/_foo_branding.scss.

I would rather do something like:

$ sass --watch . --ignore brands/foo --ignore brands/bar

The directory structure is something like this:

• app
  • a/_style.scss
  • b/_style.scss
  • c/_style.scss
• brands
  • foo/foo_branding.scss (imports a/_style.scss, etc)
  • bar/bar_branding.scss
  • my_brand/my_brand_branding.scss

This isn't a planned feature. You can always specify files individually if you want finer-grained control.
