Plugin does not work with Cucumber 2.0

[jhansche]

$ bundle exec yardoc
[warn]: Error loading plugin 'yard-cucumber'
[warn]: Error loading plugin 'yard-cucumber'

The plugin can't work with a Cucumber 2.0 dependency. There are some bugs in Cucumber 1.3 that have only been fixed in 2.0 and later.

Can someone be specific about the issues? A backtrace would give us a place to start, but a failing automated test would be ideal. We can either make changes to Cucumber's API or help fix this plugin or both. But we need more information! 😄

That's all the information that I can see... I don't know how to make yardoc print a backtrace for why there was an error loading the plugin. Once I find out how to get more information, I'll try to report that here

Let me paste that here as well. Unfortunately yard does not print backtrace of plugins that failed to load (too bad IMO). By modifying the gem I managed to get to the issue (by modifying gem to stop requiring version 1.3):

[2] pry(main)> require 'yard-cucumber'
LoadError: cannot load such file -- cucumber/parser/gherkin_builder
from /home/avalon/.rvm/rubies/ruby-2.0.0-p451/lib/ruby/site_ruby/2.0.0/rubygems/core_ext/kernel_require.rb:55:in `require'

That's from lib/yard-cucumber.rb. @mattwynne, is that helpful?

And here's reply from @mattwynne from the other issue:

That file is gone, and has been replaced by https://github.com/cucumber/cucumber-ruby-core/blob/master/lib/cucumber/core/gherkin/ast_builder.rb

I think if yard-cucumber is going that deep, it's going to need some fundamental changes in order to work with 2.0.

I'm happy to support that effort, but it will need to be done in the yard-cucumber repo.

Hmm, I don't know how this is usually tested (there are no tests). However, I just commented out the offending require, updated the cucumber dependency to ~>2.0 and ran the rake task to build and serve the examples directory

bundle exec rake server

Everything seemed to run just fine without the require :s

I then rolled the dependency back to ~>1.3 and it still works fine! Does anyone know what this require 'cucumber/parser/gherkin_builder' is for?

There don't seem to be any references to GherkinBuilder in the source

@pghalliday , I pushed your changes to ruby-gems as a band-aid solution for folks who want to use yard in their projects still, without building from github.

@tk8817 cool, thanks
