Fast Gherkin lexer and parser based on Ragel. Gherkin is two things:
Supported platforms:
Due to the cross-platform nature of this library, you have to install a lot of tools to build gherkin yourself. In order to make it easier for occasional contributors to get the development environment up and running, you don‘t have to install everything up front. The build scripts should tell you if you are missing something. For example, you shouldn‘t have to install MinGW to build windows binaries if you are a Linux user and just want to fix a bug in the C code.
These are the minimal tools you need to install:
With this minimal toolchain installed, install Ruby gems needed by the build:
gem install bundler bundle install
Running RSpec and Cucumber tests
rake clean spec cucumber
If the RL_LANGS environment variable is set, only the parsers for the languages specified there will be built. E.g. in Bash, export RL_LANGS="en,fr,no". This can be quite helpful when modifying the Ragel grammar.
See subsections for building for a specific platform.
You‘ll need GCC installed.
Build the gem with:
rake build
You must install JRuby to build the pure Java jar or the JRuby gem:
rvm install jruby rvm use jruby rvm gemset create cucumber rvm use @cucumber gem install bundler bundle install
Now you can build the jar with:
rake clean jar
In order to build and test Gherkin for Javascript you must install:
Now you can build the Javascript with:
rake js cd js npm install
And you can try it out with node.js:
node js/example/print.js spec/gherkin/fixtures/1.feature
You can also try out Gherkin running in the browser (likely to move to a separate project):
# Pull in the Ace (http://ace.ajax.org/) editor: git submodule update --init # Open a sample Gherkin-powered editor in Chrome open js/example/index.html
If you‘re hacking and just want to rebuild the English parser:
rake js/lib/gherkin/lexer/en.js
You must install Mono and IKVM to build the pure .NET dll and the IronRuby gem:
Now you can build the .NET dll with:
rake ikvm
In order to build Windows binaries (so we can release Windows gems from OS X/Linux) we need to set up rake-compiler.
github.com/luislavena/rake-compiler/
Now, let‘s install MinGW…
I didn‘t want to install macports (I‘m on homebrew) and I couldn‘t figure out how to build MinGW myself. I got prebuilt binaries (version 4.3.0): crossgcc.rts-software.org/doku.php - just add the bin folder to your PATH
You must install MinGW rubies to build gems fow Windows. First you need to download and install MinGW:
OS X users can get it from crossgcc.rts-software.org/doku.php Once you have installed it, add this to your .bashrc:
export PATH=$PATH:/usr/local/i386-mingw32-4.3.0/bin
Now, let‘s install some rubies. Make sure you have openssl installed first.
brew install openssl # 1.8.6 # Don't worry about inconsistent patchlevels here. It works. rvm install 1.8.6-p399 rvm use 1.8.6-p399 rvm gemset create cucumber rvm use @cucumber gem install bundler bundle install rake-compiler cross-ruby VERSION=1.8.6-p287 # 1.9.1 # Later 1.9.1 patch levels or 1.9.2 don't compile on mingw. # The compiled binaries should still work on 1.9.2 rvm install 1.9.1-p243 rvm use 1.9.1-p243 rvm gemset create cucumber rvm use @cucumber gem install bundler bundle install rake-compiler cross-ruby VERSION=1.9.1-p243
