- Written in Python.
- Support fuzzy and regex searching.
- Full-featured.
- Well-designed fuzzy matching algorithm.
- Extensible.
Please see the CHANGELOG for a release history.
Wiki.
A list of community extensions can be found in the Extensions wiki.
- vim7.3 or higher. Only support 7.4.1126+ after v1.01.
- Python2.7+ or Python3.1+.
- To use the popup mode, neovim 0.5.0+ or vim 8.1.1615+ are required.
For vim-plug user:
Plug 'Yggdroot/LeaderF', { 'do': ':LeaderfInstallCExtension' }LeaderF is already very fast. If you'd like better performance, install the C extension of the fuzzy matching algorithm, which is more than 10 times faster.
To install the C extension, firstly, make sure python2 and/or python3 commands are available on Linux/Unix/MacOS and py -2 and/or py -3 commands are available on Windows.
-
Install the C extension
:LeaderfInstallCExtension
There may be some errors during the installation, please google the error messages to resolve it.
For example,"error: Unable to find vcvarsall.bat", you can turn to here for help. -
Uninstall the C extension
:LeaderfUninstallCExtension
After running any command of LeaderF, check the value of echo g:Lf_fuzzyEngine_C, if the value is 1, it means the C extension is loaded sucessfully.

Input formats:
-
In NameOnly mode (fuzzy mode)
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 mode)
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.
Smart Case:
-
If the characters in search pattern are all lowercase, the matching is case-insensitive. If the search pattern contains uppercase characters, all lowercase characters still are matched case-insensitively, the uppercase characters can only match upper case. So uppercase characters can speed up the narrowing down of the searching result.
e.g., input
abcDef，it can match the following strings:abcDef AbcDef abcDEf aBcDeFbut can not match the strings such as:
abcdef AbcdefNote:
abcandefare still case-insensitive.
And operator:
-
In fuzzy mode, using
' '(space) as the and operator, the candidate lines should fuzzily match all the substrings separated by space.e.g., input
abc def gh，it can match the following strings:...a.b.c...d.e.f...g.h... ...a.b.c...g.h...d.e.f... ...a.d..e.g.b.c...h..f... ...gh...def...abc...
Popup Mode is to open LeaderF in a popup window(vim 8.1.1615+) or floating window(nvim 0.4.2+).
To enable popup mode:
let g:Lf_WindowPosition = 'popup'or add --popup after each subcommand, e.g.,
Leaderf file --popup
-
Change key bindings
By default,
<Up>and<Down>are used to recall last/next input pattern from history. If you want to use them to navigate the result list just like<C-K>and<C-J>:let g:Lf_CommandMap = {'<C-K>': ['<Up>'], '<C-J>': ['<Down>']}for more detail, please refer to
:h g:Lf_CommandMap. -
Change the colors used in LeaderF
let g:Lf_PopupPalette = { \ 'light': { \ 'Lf_hl_match': { \ 'gui': 'NONE', \ 'font': 'NONE', \ 'guifg': 'NONE', \ 'guibg': '#303136', \ 'cterm': 'NONE', \ 'ctermfg': 'NONE', \ 'ctermbg': '236' \ }, \ 'Lf_hl_cursorline': { \ 'gui': 'NONE', \ 'font': 'NONE', \ 'guifg': 'NONE', \ 'guibg': '#303136', \ 'cterm': 'NONE', \ 'ctermfg': 'NONE', \ 'ctermbg': '236' \ }, \ }, \ 'dark': { \ ... \ ... \ } \ }
All the highlight groups supported are defined in LeaderF/autoload/leaderf/colorscheme/popup/default.vim.
-
Change the default mapping of searching files command
e.g.
let g:Lf_ShortcutF = '<C-P>' -
Show icons (should install fonts from https://github.com/ryanoasis/nerd-fonts)
Support commands: buffer,file,mru,window
" Show icons, icons are shown by default let g:Lf_ShowDevIcons = 1 " For GUI vim, the icon font can be specify like this, for example let g:Lf_DevIconsFont = "DroidSansM Nerd Font Mono" " If needs set ambiwidth=double
" don't show the help in normal mode
let g:Lf_HideHelp = 1
let g:Lf_UseCache = 0
let g:Lf_UseVersionControlTool = 0
let g:Lf_IgnoreCurrentBufferName = 1
