Syntax Highlighting for Gherkin (Cucumber Language)
- by Liam McLennan
SyntaxHighlighter is the de facto standard for syntax highlighting on the web. I am currently working on a tool for publishing BDD specifications on the web and I want syntax highlighting. Unfortunately, SyntaxHighlighter does not support Gherkin, the language Cucumber and SpecFlow use to define BDD specifications. Writing new language parsers for SyntaxHighlighter is very easy, so I implemented one for Gherkin. Here is what a syntax highlighted Gherkin file looks like: # A comment here
Feature: Some terse yet descriptive text of what is desired
In order to realize a named business value
As a explicit system actor
I want to gain some beneficial outcome which furthers the goal
@secretlabel
Scenario: Some determinable business situation
Given some precondition
And some other precondition
When some action by the actor
And some other action
And yet another action
Then some testable outcome is achieved
And something else we can check happens too
Like all SyntaxHighlighter brushes to use this one you need to install the brush (shBrushGherkin.js). I have also used a custom theme to get it just the way I wanted it (shThemeGherkin.css). If you would like to use my Gherkin brush you may download the code and example page.
