Hi gang,

With a little JRuby love I managed to hook Cucumber (http://cukes.info/) up to JBehave. My latest commit:
http://github.com/aslakhellesoy/cucumber/commit/855e033832e19b5ad248c57cfb4abc8f72fa2da0

What this means is that it will be possible to use Cucumber with Java, implementing steps simply by subclassing
org.jbehave.scenario.steps.Steps. I don't use the Scenario or runner classes. The README in the link above
explains why this is interesting.

I'm planning to package Cucumber in an executable cucumber.jar file so people can run it from the command line,
just like the pure ruby version.

Any thoughts on this?

Ehi Asklak,

welcome back to Java-land

Very interesting stuff - I'll have a closer look and sniff at weekend. But looks promising ...

Glad you like it. Here is how to try it out until I package a more user-friendly release:

Install jruby and git or msysgit

git clone git://github.com/aslakhellesoy/cucumber.git # A little slow - I need to http://kerneltrap.org/mailarchive/git/2007/10/7/331471
jruby -S gem install diff-lcs treetop rspec term-ansicolor
cd cucumber
git checkout -b ast
git pull origin ast
cd examples/jbehave
mvn compile jar:jar
jruby ../../bin/cucumber features
jruby ../../bin/cucumber features/trading.feature:5:22 # Only run first and last scenario

If you're on Windows you won't get coloured output (No ANSI Color support in terminal from Java AFAIK), but if you have OS X or Linux, try my
magenta colour scheme: http://wiki.github.com/aslakhellesoy/cucumber/console-colours
Also, look at the neat error output if you make any of the steps fail. Use -b to get full backtrace. --help for more.

I'm planning to do some changes so that JBehave steps can also take Cucumber table objects as input.
I'm also looking into nailgun to reduce startup overhead (JRuby's Ruby parser is slow although execution is fast)

BTW, Cucumber's output is like this:

  Scenario: Status alert can be activated                   # features/trading.feature:5
    Given a stock of prices 0.5,1.0 and a threshold of 10.0 # cukes.jbehave.examples.trader.scenarios.TraderSteps

Do you know if there is a way to get access to the line of each step (annotation or method definition) so I can append it to the class name?
I'm super rusty on Java

More later!
