Installing VoraX (A vim based Oracle IDE) on Windows

I am quite a fan of Vim and use it everyday. So it's natural that I was drawn to VoraX. I installed using the following procedure, but got stuck when connecting to the database. The error is related to Broken Pipe during connection. So if anyone has a solution for that please let me know. I will update this blog post if I find the solution.
The things we need for vorax to be installed are -

1. Oracle Sql Client
2. Gvim 7.4
3. Ruby
4. Ruby Dev Tools
5. And last, vorax itself

Lets start with Oracle Client. Vorax uses sqlplus to connect to Oracle database. So it needs to be installed and it's path added in Environment Path. I already had it installed in my machine and no further configuration was needed for it.
Next up, Gvim. Just download gvim from it's official website and install it. But the problem with that is gvim requires msvcrt-ruby192.dll. But I was unable to find a windows ruby installer that contained this specific version of the dll. So I downloaded custom gvim build from wyw.dcweb.cn which uses msvcrt-ruby200.dll. I found this link in this stackoverflow discussion. After downloading the custom build I replaced the original gvim74.exe and vim74.exe with the custom ones.
Now, it's time to install ruby. Downloaded Ruby 2.0.0-p594 and extract it in a local directory. Lets call it RUBY_DIR. Now put RUBY_DIR\bin in Environment Path.
After this we need to set up Ruby Dev Tools. Download it and extract to some local path. Let's call it's location DEV_DIR. Now open cmd and goto DEV_DIR. Execute the following command -

DEV_DIR>ruby dk.rb init

This will create a file named config.yml in DEV_DIR. Open the file with notepad and insert the RUBY_DIR location at the end of it if the line already doesn't exist and save it. Now run the following command -

ruby dk.rb install

This will install devkit.rb file in RUBY_DIR\lib\ruby\site_ruby.
Now lets start installing VoraX. First we install some ruby gems required by VoraX. For that Open a cmd and goto RUBY_DIR\bin. Now it's time to install some gems required by VoraX. Execute the following command in cmd -

RUBY_DIR\bin>gem install vorax --no-rdoc --no-ri

If you are behind a proxy set up HTTP_PROXY variable first -

set HTTP_PROXY=http://<proxy address or IP>:port

Now download vorax plugin and extract it's contents in %userprofile%\vimfiles. Make sure %userprofile%\_vimrc file contains the line "filetype plugin on".
Now when you run gvim with vorax installed. Further information can be found

My Most Used Vim Commands

I have become fond of Vi/Vim in recent years. For most of my typing works I prefer to use Vim. Well editors which provide vim emulation. So I thought why not share the vim commands that I use most.
