You can download it from the Automation Panda Github repository – the file is named gherkin_npp_udl.xml. Since I do a lot of behavior-driven test automation development, I created a UDL for Gherkin. For example, keywords may still be highlighted when not actually being used as keywords in the language. Since the highlighting doesn’t rely upon a context-free grammar, it has its limits. Users can also import and export UDLs as XML files for sharing. Stylers can set font color, size, and style.

From there, you can create new user language and set stylers for keywords, operators, and other language facets. To access this feature, simply navigate to the Language menu option, go to User Defined Language near the bottom, and choose Define your language…. This is invaluable if you use an obscure language or even create your own. One of the nifty features in Notepad++ is User Defined Language, which allows users to customize the syntax highlighting for any language. (Not a Windows user? Check out Gherkin Syntax Highlighting in Atom.) I use it all the time, especially for config files and quick edits that don’t require a bulky IDE. Seriously, if you don’t have it, download it now. It can handle just about any programming language out there. It is free, lightweight, feature-rich, and extendable. Notepad++ is an excellent text editor for Windows.
