How to compile
First of all, you need to compile KDevelop and KDevPlatform. There are 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.
First of all, go to your build directory, all the testing has to be done in this directory. Now, there are two mechanisms to test this plugin: RSpec and QtTest. RSpec is used to test the parser, and QtTest to test everything else. If you want to test the parser, you'll have to run the following commands:
cd parser/tools rspec -c -f doc parser_spec.rb
For the other components, there is an executable file for each of them. You just have to go inside its test directory and execute the tests. For example, to test the DUChain:
cd duchain/tests ./duchain
Testing using Guard
All this process can be automated by using the guard gem. Note that there is a Gemfile in the source code of this plugin. So, to get guard and its dependencies, you may want to run the
bundle command. And finally, in the root of the source tree you will have to execute the following command:
guard -w /relative/path/to/the/build/directory
Now all the tests will be run and you'll get notified. Moreover, if you install the plugin again, all tests will be executed automatically.
Generating the documentation
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.
