上一篇文章《讓人相見恨晚的vim插件：模糊查找神器LeaderF》概括性的介紹了LeaderF的基本功能，本篇對(duì)LeaderF的新功能做一下介紹。

隨著LeaderF功能的不斷增多，LeaderF的命令也在不斷的增加，給開發(fā)和使用都帶來一些不便。于是，LeaderF提供了一個(gè)統(tǒng)一的命令接口，就像shell命令一樣，不同的命令選項(xiàng)組合，帶來不同的功能。
可以通過:Leaderf -h來查看具體使用方法。

usage: Leaderf[!] [-h] [--reverse] [--stayOpen] [--input  | --cword]
                  [--top | --bottom | --left | --right | --belowright | --aboveleft | --fullScreen]
                  [--nameOnly | --fullPath | --fuzzy | --regexMode] [--nowrap]
                  {file,tag,function,mru,searchHistory,cmdHistory,help,line,colorscheme,self,bufTag,buffer,rg}
                  ...

optional arguments:
  -h, --help            show this help message and exit
  --reverse             show results in bottom-up order
  --stayOpen            don"t quit LeaderF after accepting an entry
  --input        specifies INPUT as the pattern inputted in advance
  --cword               current word under cursor is inputted in advance
  --top                 the LeaderF window is at the top of the screen
  --bottom              the LeaderF window is at the bottom of the screen
  --left                the LeaderF window is at the left of the screen
  --right               the LeaderF window is at the right of the screen
  --belowright          the LeaderF window is at the belowright of the screen
  --aboveleft           the LeaderF window is at the aboveleft of the screen
  --fullScreen          the LeaderF window takes up the full screen
  --nameOnly            LeaderF is in NameOnly mode by default
  --fullPath            LeaderF is in FullPath mode by default
  --fuzzy               LeaderF is in Fuzzy mode by default
  --regexMode           LeaderF is in Regex mode by default
  --nowrap              long lines in the LeaderF window won"t wrap

subcommands:

  {file,tag,function,mru,searchHistory,cmdHistory,help,line,colorscheme,self,bufTag,buffer,rg}
    file                search files
    tag                 navigate tags using the tags file
    function            navigate functions or methods in the buffer
    mru                 search most recently used files
    searchHistory       execute the search command in the history
    cmdHistory          execute the command in the history
    help                navigate the help tags
    line                search a line in the buffer
    colorscheme         switch between colorschemes
    self                execute the commands of itself
    bufTag              navigate tags in the buffer
    buffer              search buffers
    rg                  grep using rg

If [!] is given, enter normal mode directly.

這樣就可以用:Leaderf [options]來執(zhí)行LeaderF的命令了。例如：

每個(gè)子命令都有專有的命令選項(xiàng)，可以用:Leaderf -h來查看。例如，Leaderf mru -h:

usage: Leaderf[!] mru [-h] [--cwd] [--no-split-path] [--reverse] [--stayOpen]
                      [--input  | --cword]
                      [--top | --bottom | --left | --right | --belowright | --aboveleft | --fullScreen]
                      [--nameOnly | --fullPath | --fuzzy | --regexMode]
                      [--nowrap]

optional arguments:
  -h, --help       show this help message and exit

specific arguments:
  --cwd            search MRU in current working directory
  --no-split-path  do not split the path

common arguments:
  --reverse        show results in bottom-up order
  --stayOpen       don"t quit LeaderF after accepting an entry
  --input   specifies INPUT as the pattern inputted in advance
  --cword          current word under cursor is inputted in advance
  --top            the LeaderF window is at the top of the screen
  --bottom         the LeaderF window is at the bottom of the screen
  --left           the LeaderF window is at the left of the screen
  --right          the LeaderF window is at the right of the screen
  --belowright     the LeaderF window is at the belowright of the screen
  --aboveleft      the LeaderF window is at the aboveleft of the screen
  --fullScreen     the LeaderF window takes up the full screen
  --nameOnly       LeaderF is in NameOnly mode by default
  --fullPath       LeaderF is in FullPath mode by default
  --fuzzy          LeaderF is in Fuzzy mode by default
  --regexMode      LeaderF is in Regex mode by default
  --nowrap         long lines in the LeaderF window won"t wrap

If [!] is given, enter normal mode directly.

好多從ctrlp.vim轉(zhuǎn)過來的朋友說不習(xí)慣LeaderF自上而下顯示結(jié)果的方式，想要LeaderF也能像ctrlp一樣自下而上（最優(yōu)結(jié)果在最下面）顯示結(jié)果，為了回饋各位朋友對(duì)LeaderF的支持，現(xiàn)在LeaderF也添加了自下而上顯示搜索結(jié)果的功能：

只需要在命令后面加上--reverse即可，或者也可以一勞永逸，在vimrc里面加上
let g:Lf_ReverseOrder = 1 。

LeaderF支持用空格（可以用g:Lf_AndDelimiter來修改）作為And操作符來進(jìn)行模糊匹配。當(dāng)匹配已經(jīng)匹配到字符串末尾時(shí)，可以通過敲空格和一個(gè)子串來匹配字符串的前面部分，進(jìn)行快速過濾。
NOTE: 空格分隔的每個(gè)子串都是對(duì)整個(gè)字符串的模糊匹配，而不是精確匹配。

可以通過上下鍵來翻看模糊匹配歷史：

LeaderF精益求精，永無止境。
