Basic syntax highlighting and error checking of CoffeeScript is only officially available in Jetbrains RubyMine IDE – read on to get it in other IDEs.
To get the same level of support for CoffeeScript in PhpStorm (and probably in similar JetBrains IDEs such as WebStorm and PyCharm), simply copy the CoffeeScript plugin directory from a trial version of the latest version of RubyMine:
- Install RubyMine EAP
- Copy the coffeescript directory from C:\Program Files (x86)\JetBrains\RubyMine 107.261\plugins\ to C:\Program Files (x86)\JetBrains\PhpStorm 2.1\plugins\
Some third party plugins exist and are officially available for the other IDEs, although they probably come with just as little support as the solution described above. Notice that none of the following plugins are being actively developed.
