I’ve registered and been approved for a citeproc-rb project on RubyForge.  
This is to host releases of the Ruby gem (the packaging standard for Ruby).  
Once citeproc-rb matures a little it should be possible to do:

gem install citeproc-rb

I’m hoping to have a very early version over the next week or so - I’ll  
announce any releases through this list.

Regards,

Liam.

I’ve released a gem of citeproc-rb via RubyForge - not sure when or if it’ll  
turn up in the gem lists.

This is at best an early alpha release - it supports the core Zotero styles  
with the test data Bruce sent through. What is missing are a substantive set  
of test cases, and I think some refactoring of the input/output handling.  
I’m hoping to dedicate some time over the next few weeks to work on the test  
cases more systematically.

Regards,

Liam.

Works for me!

Now what? The README doesn’t seem to apply to the gem install.

Sounds good.

You should hopefully be able to run the example, e.g:

ruby examples/citeproc\_driver.rb --input test/fixtures/csl\_test\_data.json  
–content-type json --csl data/styles/ama.csl

Or used as a library, something like:

require ‘citeproc’

csl = Citeproc::CslParser.new([file or URL])  
locale = Citeproc::CslParser.new([file or URL])  
input\_filter = CSL::CslInputFilter.new  
input\_filter.parse({some JSON citations})  
processor = Citeproc::CslProcessor.new  
formatter = Citeproc::XhtmlFormatter.new  
nodes = processor.process\_bibliography(input\_filter, csl.style,  
locale.style)  
results = formatter.format(nodes)  
puts results

But yes, more documentation and some simplification of the API is needed  
too…

I’m not familiar with ruby and its package management, and I tried to  
install citeproc-rb using gem. When I run the examples as suggested in  
the README I get the same error I get when I try it from the svn repo:

./examples/…/lib/citeproc/csl\_parser.rb:25: undefined method `gem' for main:Object (NoMethodError) from ./examples/../lib/citeproc.rb:18:in`require’  
from ./examples/…/lib/citeproc.rb:18  
from examples/citeproc\_driver.rb:19:in `require’  
from examples/citeproc\_driver.rb:19

this is the output of gem query --local:

\*\*\* LOCAL GEMS \*\*\*

builder (2.0.0)  
Builders for MarkUp.

citeproc-rb (0.0.1)  
Citeproc-rb is a Ruby port of the .

sources (0.0.1)  
This package provides download sources for remote gem installation

Could you please give me a hint on what I’m doing wrong? Unfortunately  
I have no time to start digging into ruby right now.

TIA.

It seems gems isn’t loaded, but the csl\_parser.rb file then requires  
the builder gem. I believe. If you add this it should work (it does  
for me):

require ‘rubygems’

Note: I just checked in this change. Hope that’s OK Liam.
