ruby-graphviz rpm vs gem

["Guillermo Gómez S."]

I have doubt here... i guess both are different sw... but look...

[1] yum install graphviz-ruby

vs

[2] gem install ruby-graphviz

should i start packaging the 2nd, what about the first? (confused)

This appeared on adopting rubygem-state_machine (testing it):

$ ruby unit/state_test.rb
Skipping GraphViz StateMachine::State tests. `gem install ruby-graphviz`
> = v0.9.0 and try again.

...

Then i tried the existing rpm [1] without luck for state_machine, the i 
tried the gem version [2], which fixes the output warning.

If I'm understanding it correctly, it seems that the upstream graphviz 
source provides some wrappers for various languages, including ruby

http://cvs.fedoraproject.org/viewvc/rpms/graphviz/F-13/graphviz.spec?view=ma...

Where as the ruby-graphviz gem provides a pure-ruby implementation of 
some of this functionality (the specifics of which I'm not sure)

I imagine rubygem-state_machine depends on the ruby-graphiz modules and 
api, or if it doesn't it at least has a gem dependency listed for that.

Most likely the best way to proceed is to package the 
rubygem-ruby-graphviz dependency, or perhaps you can get away with 
patching state_machine to work against graphviz-ruby (though this is 
less desirable incase of API discrepancies).

Well, actually I checked graphviz-ruby binary rpm and state_machine-0.9.4.gem,
and
- while graphviz-ruby provides "gv" module
-------------------------------------
$ rpm -qlp graphviz-ruby-2.26.0-4.fc14.i686.rpm 2>/dev/null | grep 'ruby.1.8.**so$'
/usr/lib/ruby/site_ruby/1.8/i386-linux/gv.so
------------------------------------
- state_machine-0.9.4.gem actually requires "graphviz" module for graphviz related
   tests:
------------------------------------
$ cat -n test/unit/event_test.rb
    761  begin
    762    # Load library
    763    require 'rubygems'
    764    gem 'ruby-graphviz', '>=0.9.0'
    765    require 'graphviz'
    793  rescue LoadError
    794    $stderr.puts 'Skipping GraphViz StateMachine::Event tests. `gem install ruby-graphviz` >= v0.9.0 and try again.'
    795  end
-----------------------------------
   So graphviz-ruby does not provide this dependency.

You can create "rubygem-ruby-graphviz" srpm from ruby-graphviz(-0.9.16).gem
and import it into Fedora if you want to enable all tests.

Thank u very much all, i will proceed creating rubygem-ruby-graphviz 
srpm from the gem, first for testing purposes, then as stand alone 
rubygem for Fedora. I think is it not only for testing purposes included 
in state_machine, my guess is state_machine implements some 
functionalities based en grahviz based on this gem.

Meanwhile, state_machine new spec/srpm has been posted for review 
https://bugzilla.redhat.com/show_bug.cgi?id=622904

There's no issue so far with it.
