File Navigation in Vim

Task Ruby
Opening files quickly Install Command-T from GitHub.
Custom Command-T mappings
" Open files with <leader>f
map <leader>f :CommandTFlush<cr>\|:CommandT<cr>
" Open files, limited to the directory of the current file, with <leader>gf
" This requires the %% mapping found below.
map <leader>gf :CommandTFlush<cr>\|:CommandT %%<cr>
Custom Rails-specific Command-T mappings
map <leader>gv :CommandTFlush<cr>\|:CommandT app/views<cr>
map <leader>gc :CommandTFlush<cr>\|:CommandT app/controllers<cr>
map <leader>gm :CommandTFlush<cr>\|:CommandT app/models<cr>
map <leader>gh :CommandTFlush<cr>\|:CommandT app/helpers<cr>
map <leader>gl :CommandTFlush<cr>\|:CommandT lib<cr>
map <leader>gp :CommandTFlush<cr>\|:CommandT public<cr>
map <leader>gs :CommandTFlush<cr>\|:CommandT public/stylesheets<cr>
Other Rails-specific file keystrokes
map <leader>gr :topleft :split config/routes.rb<cr>
map <leader>gg :topleft 100 :split Gemfile<cr>
Show the current routes in the split
function! ShowRoutes()
  " Requires 'scratch' plugin
  :topleft 100 :split __Routes__
  " Make sure Vim doesn't write __Routes__ as a file
  :set buftype=nofile
  " Delete everything
  :normal 1GdG
  " Put routes output in buffer
  :0r! rake -s routes
  " Size window to number of lines (1 plus rake output length)
  :exec ":normal " . line("$") . "_ "
  " Move cursor to bottom
  :normal 1GG
  " Delete empty trailing line
  :normal dd
map <leader>gR :call ShowRoutes()<cr>
Edit or view files in same directory as current file
cnoremap %% <C-R>=expand('%:h').'/'<cr>
map <leader>e :edit %%
map <leader>v :view %%
Make the current window big, but leave others context
set winwidth=84
" We have to have a winheight bigger than we want to set winminheight. But if
" we set winheight to be huge before winminheight, the winminheight set will
" fail.
set winheight=5
set winminheight=5
set winheight=999
Use :A to switch between production and test code in Rails Install rails.vim from GitHub.
Run only the tests you want while moving around
function! RunTests(filename)
    " Write the file and run tests for the given filename
    :silent !echo;echo;echo;echo;echo
    exec ":!bundle exec rspec " . a:filename

function! SetTestFile()
    " Set the spec file that tests will be run for.
    let t:grb_test_file=@%

function! RunTestFile(...)
    if a:0
        let command_suffix = a:1
        let command_suffix = ""

    " Run the tests for the previously-marked file.
    let in_spec_file = match(expand("%"), '_spec.rb$') != -1
    if in_spec_file
        call SetTestFile()
    elseif !exists("t:grb_test_file")
    call RunTests(t:grb_test_file . command_suffix)

function! RunNearestTest()
    let spec_line_number = line('.')
    call RunTestFile(":" . spec_line_number)

" Run this file
map <leader>t :call RunTestFile()<cr>
" Run only the example under the cursor
map <leader>T :call RunNearestTest()<cr>
" Run all test files
map <leader>a :call RunTests('spec')<cr>
Switch between the last two files
nnoremap <leader><leader> <c-^>
