Question

我最近碰到了这个奇怪的Vim插件，无法弄清楚它的用途。

几乎没有记录，nobdy真的在谈论它，但对其他一些插件来说似乎很重要。

我发现的全部都在这里：

http://www.vim.org/scripts/script.php?script_id=3252

和

https://github.com/eparreno/vim-l9

但他们只是说＆＃34;它是一个图书馆＆＃34;和＆＃34;查看源代码＆＃34;。

任何人都知道这个lib是什么，如果我应该拥有它，出于什么目的，或者我是否可以删除它，直到某些其他插件中的某些依赖项未得到满足？

我注意到最近来自Vundle的几个地方对L9的引用。没错，一开始就没有记录。但主要的源文件autoload/l9.vim中有很好的评论。它是一组通用实用功能。以下是其大部分API，增加了Vim对列表，数字，字符串，行，路径，文件，缓冲区，窗口，搜索等的处理：

" returns false if the caller script should finish.

function l9#unique(items)

" [ [0], [1,2], [3] ] -> [ 0, 1, 2, 3 ]

function l9#moveToBufferWindowInCurrentTabpage(bufNr)

" returns 0 if the buffer is not found.
function s:moveToOtherTabpageOpeningBuffer(bufNr)

" move to a window containing specified buffer.
" returns 0 if the buffer is not found.
function l9#moveToBufferWindowInOtherTabpage(bufNr)
