markium

Inline markdown formatting and pygments syntax highlighting plugin for the Adium chat client.

🚨 WARNING: THIS PROJECT IS DEAD 🚨

FAIR WARNING: I don't claim to know what the hell I'm doing in Objective-C or Cocoa or even XCode. Use at your own risk.

Features

• Markdown formatting and code syntax highlighting in your chat windows
• Inline code elements and quick bold, italic and ~~strikethrough~~ formatting
• Uses redcarpet Yay! Github-flavored Markdown!
• Fenced code blocks (```: triple-tick) with language specification

Why?

I'm a web developer. I chat a lot with other developers. Textual conversation and programming vocabulary can get very dicey ("put this before this. No, that, not this!"). Inline code references and GFM make the task of talking about code a whole lot easier.

Waaay Beta

Like I said, I'm a web developer (+designer) - this is my first dive into ObjC and the water is cold. I am 100% certain there are better ways to get the results (probably better results, too); I'm just not good enough. Please – by all means – fork me and right all the evils I have committed!

Borrowed Projects

Awesomely cool projects borrowed from:

• Adium
• redcarpet: Github-flavored markdown
• pygments: Syntax highlighting
• Mnmlsm: Florian Pichler's beautiful MessageView Style
• HTMLParser: Ben Reeves' ObjC library

Installation

Quite a few nasty prerequisites, but the basics go like this:

1. Install the gems redcarpet, albino, and nokogiri

   $ gem install redcarpet albino nokogiri
   

2. Install pygments

   $ easy_install Pygments
   

3. Open markium.AdiumMessageView to install the MessageView Style Xtra

4. Open bin/markium.AdiumPlugin to install the ContentFilter plugin (requires Adium restart)

5. Activate the MessageView Style Preferences->Messages and select one of the 3.x variants. Make sure that "Show received message fonts" and "Show received message colors" are both enabled.

Using with Other Styles

The AIHTMLContentFilter method that is used to alter HTML displayed text only works with certain styles. The MessageViewVersion (listed in the view's plist) value for the style must be set to 4. Don't ask me why, there is almost no documentation on the different MessageViewVersions (I had to traipse through Adium's source to figure it out). If you want to see if your favorite MessageView Style will support it, right click on the package (usually located in ~/Library/Application Support/Adium 2.0/Message Styles/), select "Show Package Contents" and open Content/info.plist in an editor. Look for:

...
<key>MessageViewVersion</key>
<integer>4</integer>
...

CSS Additions for Syntax Highlighting

If you want to enable syntax highlighting in your MessageView Style, you can copy and #import the markdown_additions.css file to your own style from:

/markium.AdiumMessageStyle/Contents/Resources/markdown_additions.css

To Do

1. Get help making more of this thing self-contained and less reliant on other packages/languages.
2. Add markdown additions css to more MessageView Styles
3. Auto-inline images?
4. Unit tests
