" 設定
call unite#set_substitute_pattern('file', '^;v', '~/.vim/*')
call unite#set_substitute_pattern('file', '^;b', '~/.vim/bundle/*')
call unite#set_substitute_pattern('file', '^;g', '/var/lib/gems/1.8/gems/*')

" 下記の A, B, C の方法で Unite を起動したとき、substitute_pattern
" の動作を３つの入力パターンで確認した。
"
" cd ~/.vim
" gvim

" A: file
Unite file -buffer-name=file
" =================================================================

" ;v => OK
" ;b => OK
" ;g => OK /var/lib/gems/1.8/gems 配下のCandidate が出る。

" B: file_rec
" =================================================================
Unite file_rec/async -buffer-name=file

" ;v => OK
" ;b => OK
" ;g => NG ;g のまま

" C: file_rec
Unite file_rec -buffer-name=file
" ;v => OK
" ;b => OK
" ;g => NG ;g のまま

" 違い
" file_rec, file_rec/async とも、;v, ;b の絞り込み結果が相対パス表示なのに対して、A の file subustitute_pattern 発動後の candidate が絶対パス表示になる。
