I’ve begun to explore Radiant as a publishing/blogging platform. At the moment, I’m trying to nail down is how to best format command-line output or code as the majority of the content published will be of a technical nature. Can someone point me in the right direction of what I should use to get the “desired” affect 😛 I found [Background Photos 100% For Free to Download | Wallpapers.com](http://alexgorbatchev.com/SyntaxHighlighter/) which is a JavaScript-based solution. Unfortunately it doesn’t appear to support formatting/highlighting command-line output. What’s the best Radiant filter / JS library / some-other-solution out there for both command-line output and code syntax highlighting? Thanks in advance! Fima ---

Thanks John - will take a look. Do you have any public pages you can share as examples? ---

[http://johnmuhl.com/tmp/kramdown-coderay](http://johnmuhl.com/tmp/kramdown-coderay) the kramdown looks like (replace - with space): ----def meth options ------p options ----end {:lang=“ruby”} just a standard markdown code block followed by {:lang=“lang”} [http://coderay.rubychan.de/](http://coderay.rubychan.de/) list the supported languages. ---

Ok, so I’m sure you can tell by this last post of mine that I’m a complete noob. Looks like it’s kramdown that I would use for the markdown and then coderay for syntax highlighting. Fine. Figured out that part. So now the question is how do I use kramdown + coderay w/ radiant? 😛 Thanks again. ---

don’t mind me - I’m just going to update this thread as I figure more things out … looks like there’s a kramdown radiant filter 🙂 [http://ext.radiantcms.org/extensions/192-kramdown-filter](http://ext.radiantcms.org/extensions/192-kramdown-filter) now just need to figure out how to leverage the coderay gem 😛 ---

I can’t quite figure out how to use the coderay gem. Could you provide some guidance around how to do it? I see that there are filters available to me via extensions that allow me to leverage different text markups - I’m guessing I’d have to use the coderay gem in a different manner? Or should it be exposed as a filter like the others? Thanks for the help. ---

So looks like there are two radiant extensions below that allow you to leverage the coderay gem: [https://github.com/phallstrom/code\_ray](https://github.com/phallstrom/code_ray) > **[GitHub - alno/radiant-code-extension: Extension to highlight code in Radiant CMS](https://github.com/alno/radiant-code-extension)** > > Extension to highlight code in Radiant CMS. Contribute to alno/radiant-code-extension development by creating an account on GitHub. I’m inclined to use the the 2nd one since it supports other syntax highlighters beyond coderay. What are your thoughts on which one to use? Also, I’m curious, why use kramdown over the existing Markdown radiant filter? Speed or other reasons as well? Thanks! ---

What are your thoughts on which one to use? I tried to use alno/radiant-code-extension for the same reason but had to switch over to phallstrom/code\_ray because I couldn’t overcome an processor error and I decided that coderay was an acceptably easy library to implement and use. Ultimately, I forked it so I could merge envygeek’s fork and pallstrom’s. Kevin ---

Looks like coderay is working well. I installed: coderay gem + radiant extension @ [GitHub - phallstrom/code\_ray: A RadiantCMS extension to provide syntax highlighting via the CodeRay ruby gem](https://github.com/phallstrom/code_ray) and now I can specify \ blocks! not sure what the benefits are of kramdown over the existing Markdown radiant filter that comes with the “Coffee blog” template. If you guys can shed some light on why kramdown is a better option I’d appreciate it. Thanks again! Fima ---

gem install radiant-kramdown\_filter-extension gem install coderay then in config/environment.rb … require ‘radius’ require ‘coderay’ # add this line … config.gem ‘will\_paginate’, :version =\> ‘~\> 2.3.11’ config.gem ‘radiant-kramdown\_filter-extension’ # add this line … then restart radiant and you should be all set. ---
