1. 记得更改ag.exe,perl.exe,es.exe,git.exe 哈，在.vimrc的第943行，搜索一下即可
并且把.vim目录下的ag.exe添加到path路径下，这样你就可以愉快的`,a`,命令行显示`:Ack everything`

2. 安装ctags(ubuntu: apt-get install exuberant-ctags)和cscope(apt-get install cscope)

" --- type to search the word in all files in the current dir
nmap <leader>q :Ag <c-r>=expand("<cword>")<cr><cr>
nnoremap <space>/ :Ag

In Windows, you should not use file_rec/async source. It is too slow and not easy to use. You should use file_rec source instead.

:TagsGenerate

This command will generate one or more tags files but only if the main tags file exists. The presence of that file acts as an indicator actually. By the main tags file I mean the "tags" file collecting tags from all files and subdirectories of the project root directory.

The most significant one is that Universal-ctags doesn't load ~/.ctags and ./.ctags at starting up time. Instead, it loads ~/.ctags.d/*.ctags and ./.ctags.d/*.ctags

G:\IntellijHome\hutool>cscope -Rbq
cscope: -q option mismatch between command line and old symbol database

sort: cannot read: /tmp/cscope.16808/cscope.1: No such file or directory
cscope: cannot create inverted index; ignoring -q option
cscope: removed files ncscope.in.out and ncscope.po.out

D:\Temp> type cs.bat
@echo off
set path=f:\cygwin\bin;
cscope -Rbkq

出现E623 无法生成cscope进程”

在命令行窗口下可以直接用cscope命令了吗？用cscope -h试试，看能不能执行成功
如果已经可以，你所csprg的名字(在.vimrc中设置)设置成下面的试试：
set csprg=cscope

if has("cscope")
   "  set csprg="F:\cygwin\bin\cscope.exe"              "指定用来执行 cscope 的命令
     set csprg=cscope              "指定用来执行 cscope 的命令
   set csto=1                             "先搜索tags标签文件，再搜索cscope数据库
   set cst                                "使用|:cstag|(:cs find g)，而不是缺省的:tag
   set nocsverb                           "不显示添加数据库是否成功
   " add any database in current directory
   if filereadable("cscope.out")
      cs add cscope.out                   "添加cscope数据库
   endif
   set csverb                             "显示添加成功与否
endif
"cscope"
   " in case your cscope execute is not in system path.
    " let g:cscope_cmd = 'D:/tools/vim/cscope.exe'
    " s: Find this C symbol
    map <leader>fs :call CscopeFind('s', expand('<cword>'))<CR>
    " g: Find this definition
    map <leader>fg :call CscopeFind('g', expand('<cword>'))<CR>
    " d: Find functions called by this function
    map <leader>fd :call CscopeFind('d', expand('<cword>'))<CR>
    " c: Find functions calling this function
    map <leader>fc :call CscopeFind('c', expand('<cword>'))<CR>
    " t: Find this text string
    map <leader>ft :call CscopeFind('t', expand('<cword>'))<CR>
    " e: Find this egrep pattern
    map <leader>fe :call CscopeFind('e', expand('<cword>'))<CR>
    " f: Find this file
    map <leader>ff :call CscopeFind('f', expand('<cword>'))<CR>
    "" i: Find files #including this file
    map <leader>fi :call CscopeFind('i', expand('<cword>'))<CR>
    map <leader>l :call ToggleLocationList()<CR>

使用方法
ag 'hx' /www/t086.com

常用参数
-i 忽略大小写
-l 只列出文件名
-g 文件名匹配
--php 只搜索php文件
--ignore-dir 忽略目录

虽然ctrlspace被我从vim配置中移除了，但是他整合的几个概念还是有意思

 think of ctrlspace


In one workspace(&W : workspace), there're many bookmarks(&b : Bookmark). You can open files(&o: Open) of a bookmark(&b) in one tag(&l Lists, and open another file(&o) of a bookmark(&b) in another tag(&l :Lists). Once you opend one file(&o), actually, you created one buffer(&h Home)


1. Workspace(w  workspace)
2. Bookmark(b  bookmark)
3. Files(&o Open)
4. Tags(&l Lists)
5. Buffers(&h Home)


so, when click F2 in the vim, then o can view file lists, l can view many opened tas, h can view  buffers for opened files. 

call textobj#user#plugin('datetime', {
\   'markdate': {
\     'pattern': '\<\d\d\d\d-\d\d-\d\d\>',

\   },
\   'time': {
\     'pattern': '\<\d\d:\d\d:\d\d\>',

ah                      A section segment (the area between two consecutive
                        headings) including trailing empty lines.
ih                      A section segment without trailing empty lines.

    :VimwikiTable cols rows
    Create a table with the given cols and rows

    :VimwikiTable cols
    Create a table with the given cols and 2 rows

a\                      A cell in a table.
i\                      An inner cell in a table.
ac                      A column in a table.
ic                      An inner column in a table.

al                      A list item plus its children.
il                      A single list item.

*:VimwikiTableMoveColumnLeft* , *:VimwikiTableMoveColumnRight*
    Move current column to the left or to the right:

    Commands are mapped to <A-Left> and <A-Right> respectively.

  [[file:/home/somebody/a/b/c/music.mp3]]

  [[file#anchor]]

For example, consider the following file "Todo.wiki": >
  = My tasks =
  :todo-lists:
    == Home ==
        - [ ] bathe my dog
    == Work ==
        - [ ] beg for *pay rise*
    == Knitting club ==
        === Knitting projects ===
            - [ ] a *funny pig*
            - [ ] a *scary dog*

Then, to jump from your index.wiki directly to your knitting projects, use: >
  [[Todo#Knitting projects]]

Or, to jump to an individual project, use this link: >
  [[Todo#funny pig]]

Or, to jump to a tag, use this link: >
  [[Todo#todo-lists]]

If there are multiple instances of an anchor, you can use the long form which
consists of the complete header hierarchy, separated by '#': >
 [[Todo#My tasks#Knitting club#Knitting projects#scary dog]]

If you don't feel like typing the whole stuff, type just [[Todo# and then
|i_CTRL-X_CTRL-O| to start the omni completion of anchors.

For jumping inside a single file, you can omit the file in the link: >
  [[#pay rise]]

A tag is a sequence of non-space characters between two colons: >
        :tag-example:
It is allowed to concatenate multiple tags in one line: >
        :tag-one:tag-two:
<
If placed in the first two lines of a file, the whole file is tagged.  If
placed under a header, within the 2 lines below it, the header is then tagged
with this tag, and the tag search commands will jump to this specific header.
Otherwise, the tag stands of its own and the search command jumps directly to
it.

你可以用如下命令取得所有的标记的列表：
:marks
你会注意到有一些特殊的标记，包括：

 ' 跳转前的位置( <2018-06-08 16:37> 输入两次'跳转回上一次访问位置

 " 最后编辑的位置

 [ 最后修改的位置的开头

 ] 最后修改的位置的结尾

Set makeprg=perl

然后就可以打开vim *.pl
在命令行模式下执行 :make %
%号指代的旧时的当前文件

This is a list of directories which will be searched when using the
|gf|, [f, ]f, ^Wf, |:find|, |:sfind|, |:tabfind| and other commands,
provided that the file being searched for has a relative path (not
starting with "/", "./" or "../").  The directories in the 'path'
option may be relative or absolute.
- Use commas to separate directory names
:set path=.,/usr/local/include,/usr/include
