Ruby Refactoring Tool for Vim

I love vim! It's my editor of choice when I am developing software.

Currently (for the last 4 years at least) I have been working mainly with the Ruby Programming Language.

I have been missing a refactoring tool for a while (like the ones you can find in IDE's) while I am developing, but I never had the nerve to dwell into vim script to actually code my own.

Recently (a couple of weeks ago) Gary Bernhardt presented his vim configuration in the Software Craftsmanship User Group UK and he showed us the two refactoring patterns he has written in vim script.

Initially I just thought "cool", but it didn't really sink in until a couple of weeks later.

So now I have decided to code this in vim script, but I am not sure how far I will go with it (clone at your own risk).

N.B. 'Rename Local Variable', 'Rename Instance Variable' and 'ExtractMethod' require matchit.vim:

Implemented commands/patterns:

:RAddParameter           - Add Parameter 
:RInlineTemp             - Inline Temp
:RConvertPostConditional - Convert Post Conditional
:RExtractConstant        - Extract Constant          (visual selection)
:RExtractLet             - Extract to Let (Rspec)
:RExtractLocalVariable   - Extract Local Variable    (visual selection)
:RRenameLocalVariable    - Rename Local Variable     (visual selection/variable under the cursor, *REQUIRES matchit.vim*)
:RRenameInstanceVariable - Rename Instance Variable  (visual selection, *REQUIRES matchit.vim*)
:RExtractMethod          - Extract Method            (visual selection, *REQUIRES matchit.vim*)

Default bindings:

:nnoremap <leader>rap  :RAddParameter<cr>
:nnoremap <leader>rcpc :RConvertPostConditional<cr>
:nnoremap <leader>rel  :RExtractLet<cr>
:vnoremap <leader>rec  :RExtractConstant<cr>
:vnoremap <leader>relv :RExtractLocalVariable<cr>
:nnoremap <leader>rit  :RInlineTemp<cr>
:vnoremap <leader>rrlv :RRenameLocalVariable<cr>
:vnoremap <leader>rriv :RRenameInstanceVariable<cr>
:vnoremap <leader>rem  :RExtractMethod<cr>
