It seems like I got into a hacking frenzy after yesterday’s Ruby plugins for Kate. Today I sat down and took another look at the KRubyPluginFactory to implement KIO slave support.
So here it is, our very first Ruby Hello World KIO slave:
# kate: space-indent on; indent-width 2;
class Main < KIO::SlaveBase
def initialize protocol, pool_sock, app_sock
super protocol, pool_sock, app_sock
def get url
data Qt::ByteArray.new('Hello World from our first Ruby KIO slave!')
We’ll also need a rubytest.protocol file that describes our new protocol:
To test it, you just have to type rubytest:/ into konqi’s addressbar and you should see nice hello world greeting.
Some more info on the structure of a Ruby kio slave: the Ruby script always has to be named ‘main.rb’ and the SlaveBase derived class always ‘Main’. The module name is the camelized form of the protocol (so a protocol ‘foo_bar’ would map to a module name ‘FooBar’). The script has to reside in <kde prefix>/share/apps/kio_<protocol name>.
The .protocol file itself should be installed to <kde prefix>/share/kde4/services.
As with the Kate plugin, I packaged this example in a tarball. It ships a Makefile and can easily be installed to your home directory with ‘make install’.
I committed this feature to both trunk and the 4.5 branch – so you can soon start coding your own KIO slaves in Ruby! 🙂
