vim插件Leaderf的功能补充

 1、快捷键及排除搜索目录设置：

nnoremap <leader>f :LeaderfFile ~<cr>
noremap <F2> :LeaderfFunction!<cr>
let g:Lf_WildIgnore = {
            \ 'dir': ['.svn','.git','.hg','.vscode','.wine','.deepinwine','.oh-my-zsh'],
            \ 'file': ['*.sw?','~$*','*.bak','*.exe','*.o','*.so','*.py[co]']
            \}

" 按Esc键退出函数列表
let g:Lf_NormalMap = {
	\ "File":   [["<ESC>", ':exec g:Lf_py "fileExplManager.quit()"<CR>']],
	\ "Buffer": [["<ESC>", ':exec g:Lf_py "bufExplManager.quit()"<CR>']],
	\ "Mru":    [["<ESC>", ':exec g:Lf_py "mruExplManager.quit()"<CR>']],
	\ "Tag":    [["<ESC>", ':exec g:Lf_py "tagExplManager.quit()"<CR>']],
	\ "Function":    [["<ESC>", ':exec g:Lf_py "functionExplManager.quit()"<CR>']],
	\ "Colorscheme":    [["<ESC>", ':exec g:Lf_py "colorschemeExplManager.quit()"<CR>']],
	\ }
" let g:Lf_UseCache = 0

2、安装搜索工具rg：

curl -LO https://github.com/BurntSushi/ripgrep/releases/download/0.10.0/ripgrep_0.10.0_amd64.deb
sudo dpkg -i ripgrep_0.10.0_amd64.deb

" ack
if executable('rg')
    let g:ackprg = 'rg --vimgrep'
endif
nnoremap <leader>F :Ack!<space>
let g:ackhighlight = 1
let g:ack_autoclose = 1
