|Hi there! I'm sorry to tell you that this page is still under construction. The responsible for this mess is Miquel (mssola on IRC).|
First of all, you need to compile KDevelop and KDevPlatform. There're instructions on how to do this here: KDevelop4/HowToCompile. If you have succeeded in installing KDevelop and KDevPlatform, you can install the Ruby plugin in pretty much the same way. First, download the source code:
git clone git://anongit.kde.org/kdev-ruby
Then you can compile it by doing the following:
mkdir build cd build cmake -DCMAKE_INSTALL_PREFIX=$HOME/kdevelop4 ../ make make install
Last but not least, make sure to run
kbuildsycoca4 after the installation process.
This plugin needs to have a file with all the Ruby built-in modules, classes, constants, etc. This file is called builtins.rb and you can find it in the documentation/ directory. This file will always be available, but if you want to generate it again, you have to follow some simple steps. First of all, you need to get the Ruby source code (the MRI implementation). You can download it here or, alternatively, you can use svn or git like this:
svn co http://svn.ruby-lang.org/repos/ruby/trunk ruby git clone https://github.com/ruby/ruby.git
This is a necessary step because the documentation/kdevruby_doc.rb script needs the path of the Ruby source code as the first parameter. The second parameter to be passed to this script will be the name of the output file. Therefore, to generate the builtins.rb file we just have to execute:
cd documentation ruby kdevruby_doc.rb /absolute/path/to/the/ruby/source/code builtins.rb
Note that this process can take a while. After this, we'll have a brand new builtins.rb file.
