Fenced code blocks don't work

[DasyatidPrime]

Supposedly Maruku supports the features from Markdown Extra, and they appear to be enabled by default. On that page, however, there is a description of “fenced code blocks” which are activated by lines of tildes. These don't seem to get translated by Maruku:

$ irb1.9.1
irb(main):001:0> require 'maruku'
=> true
irb(main):005:0> Maruku.new("foo\n\n~~~~\nfoo\n~~~~").to_html
=> "<p>foo</p>\n\n<p>~~~~ foo ~~~~</p>"

It's possible I'm missing some way of enabling these, but a few quick greps of the source turned up nothing.

Correct. The extension is not enabled here.

It is, in my Nokogiri branch.

Any hints on how to enable Maruku with support for fenced code blocks in Jekyll (intelligible to a non-ruby-developer)? To start, how do I install the gem corresponding to the Nokogiri branch?

[distler]

I don't know how to do that from Rubgems, but Bundler handles that task just fine.

[cboettig]

Thanks for the link, just installed the bundler gem. I'm a bit dense, looks like I need to run

gem "maruku", :git => "https://github.com/distler/maruku.git" :branch => "nokogiri"

to use your github branch for the Maruku gem. I tried running that command from the command line and bash just gets confused. How was I supposed to have done it?

[cboettig]

@distler I cloned your Nokogiri branch and ran bundle install successfully to install it. Running Jekyll with Maruku as the interpreter, I still do not get fenced code blocks like ~~~ or

 ```xml 
 <?xml version="1.0" encoding="UTF-8"?>

to display properly. Perhaps I haven't convinced it to use the right version of maruku? Have I missed something?

[distler]

I believe that you need at least five '~'s to signal the start of a fenced codeblock, and an equal (or larger) number to end one.

We should support three-backtick fenced code blocks as well.

Fenced code blocks (tildes and backticks) can be enabled in 0.7.0 using the :fenced_code_blocks setting. This ticket is still open to turn them on by default.
