.vimrc file for Ggrep key binding

" Does a git grep of whatever you are currently searching for.  Requires
" fugitive.vim
" Bugs:
"   Always does a case dependent search, even if vim is ignorecase mode.
"   Doesn't understand searches with spaces in them (usually you can just
"     replace spaces with dots in the Vim search).
"   Doesn't understand most metacharacters that also mean something to the
"     shell.
"   Understands \<word\> and converts to a grep -w, but doesn't understand
"     asymmetric word delimiters like \<word or word\>

  let stripped = matchlist(searchterm, '^\\<\(.*\)\\>$')

" If there's a vertical split, this opens the search in the right side.
" If there is no vertical split, just does the search in the current window.
" If you accidentally do the search in the current window, use :b# to go back.
map å <C-W>l:call GgrepFromSearch()<CR>

" Creates a vertical split and does the search in the right hand one.
map Å :vspl<CR><C-W>l:call GgrepFromSearch()<CR>

" For moving back and forth through the Ggrep result.
map æ :cprevious<CR>
map ø :cnext<CR>

" Looks at the character to the left, and does a shell-style autocomplete
" (ctrl-P) if we are in the middle of a word.  If there is white-space
" or beginning-of-line, it does two spaces to indent.
