Installation

To install this plugin just put the plugin files in your ~/.vim (Linux) or ~/vimfiles (Windows). For Vundle user, just add Plugin 'Yggdroot/LeaderF' to your .vimrc.

Performance

LeaderF is already very fast. If you want better performance, install the C extension of the fuzzy matching algorithm, which is more than 10 times faster. To install the C extension, follow the below:

• On Linux/Unix/MacOS:

  First, make sure python and/or python3 commands are available. Then run the installation script:

  cd ~/.vim/bundle/LeaderF
  ./install.sh
  

  Uninstall the C extension:

   ./install.sh --reverse
  
  

  If you are using vim-plug:

   Plug 'Yggdroot/LeaderF', { 'do': './install.sh' }
  
  

• On Windows:

  First, make sure py and/or py -3 commands are available. Then run the installation script:

  cd ~\.vim\bundle\LeaderF
  .\install.bat
  

  There may be some error during the installation, please google the error messages to resolve it.

  Uninstall the C extension:

   .\install.bat --reverse
  
  

  If you are using vim-plug:

   Plug 'Yggdroot/LeaderF', { 'do': '.\install.bat' }
  
  

After running any command of LeaderF, check the value of echo g:Lf_fuzzyMatch_C, if the value is 1, it means the C extension is loaded sucessfully.

Input formats:

• In NameOnly mode (fuzzy)

  'abc' is interpreted as vim's regexp 'a.\{-}b.\{-}c'. If the first character you input is ';', then the searching will be the same as in FullPath mode. If you input string as 'abc;def', then 'abc' will match the file name and 'def' will match the directory name.

• In FullPath mode (fuzzy)

  Same as in NameOnly mode except that the pattern will match the full path but not the file name only.

• In Regexp mode

  The input string is the same as the Vim's regexp.

Customization

• Change key bindings

  By default, <ESC> is the shortcut key to switch to normal mode, if you want to change it to be 'Quit from LeaderF':

  let g:Lf_CommandMap = {'<C-C>': ['<Esc>', '<C-C>']}

• Customize the statusline

  Please refer to here.

• Change the highlight of matched string

  highlight Lf_hl_match gui=bold guifg=Blue cterm=bold ctermfg=21
  highlight Lf_hl_matchRefine  gui=bold guifg=Magenta cterm=bold ctermfg=201
  

• Change the default mapping of searching files command

  e.g. let g:Lf_ShortcutF = '<C-P>'
