Did your syntax highlighting for an installed package (e.g. Jade, Coffeescript, Stylus, etc.) suddenly stop working? This helped me.
- Press command + shit + p to bring up the Command Palette (also under Tools > Command Pallette…)
- Type in “enable”
- From the dropdown menu, click on “Enable Package”
- Either an alert will pop up telling you that there are no disabled packages (sorry I couldn’t help!) OR a dropdown will appear with a list of disabled packages
- Click on the name of the syntax that was (mysteriously?) disabled, and voila. Back in business.
