fontify-face

Fontify symbols representing faces with that face.

Usage

Enable fontify-face-mode in the buffer where you want the previews to be active.

Note: the symbols are tested with facep predicate which means if the package that defines the faces is not loaded they will not be fontified. If you want to see the previews you will have to require the package that defines the faces first.

Rationale

Read the blog for a more in depth background.

During theme or package development it is useful to see how the faces look directly during development. This saves time and provides thighter feedback loop. Happy theming!
