C# scanner file for CodeRay

Added by percy li over 14 years ago

I'm a C# programmer and don't have much knowledge on RoR.

When I came to Remine, the code highlighting tool "CodeRay" doesn't support C# right now. So I think I need to replace it with another highlighting tool, or make an extension for CodeRay.

There is already a Java scanner file in the current CodeRay library. So I tried to write a C# one according to the Java one. Fortunately, it went smoothly.

The attachment file is the C# scanner I made. It is a temporary solution, because I wrote it just for CodeRay, which is also the version Remine is currently using, although there seems to be some improvements in the newer versions of CodeRay. According to the CodeRay roadmap, C# support will be added in version 1.1.


Put the csharp.rb in <redmine folder>vendor/plugins/coderay-

And then you may use <pre><code class="csharp">.... block now.

(Optional) You may add aliases in the file <redmine folder>vendor/plugins/coderay-

(Optional) You may add file extensions' mappings in the file <redmine folder>vendor/plugins/coderay- And following is my settings:

    'cs' => :csharp,
    'config' => :xml,
    'aspx' => :html,
    'resx' => :xml,
    'asax' => :html,
    'ashx' => :html,
    'xaml' => :xml,
    'csproj' => :xml,
    'xsd' => :xml,
    'xsc' => :xml,
    'xss' => :xml,
    'settings' => :xml,

Thanks for the c# scanner. It makes our code snippets much easier to read.

Where did you put coderay_vscolors.css or what did you do with it?

Append it to Redmine stylesheet by copying its contents or using @import directive:

I have wrote another C# scanner .
It is based on coderay 1.1.1.rc1 (not yet released), and tested on redmine-3.1.0 .

1. how to install my patched coderay


$ git clone

build and

$ cd coderay
$ git checkout csharp-scanner
$ gem build coderay.gemspec


$ sudo gem install ./coderay-1.1.1.rc1.gem
$ gem list coderay

*** LOCAL GEMS ***

coderay (1.1.1.rc1, 1.1.0)

2. setup your redmine

Edit redmine's Gemfile,

A. uninstall

If newer coderay will be released, you should uninstall my patched coderay.

$ sudo gem uninstall coderay -v 1.1.1.rc1

Restore redmine's original Gemfile,
run bundler again
and then restart your web server.
