|21.1| Suspend and resume
Ctrl-Z 或者 :suspand 命令挂起 vim 回到shell
GUI 下最小化 vim
回到vim，用 fg
|21.2| Executing shell commands
To execute a single shell command from Vim use ":!{command}"
:!{program} execute {program}
:r !{program} execute {program} and read its output
:w !{program} execute {program} and send text to its input
:range!{program} filter text through {program}
使用 :shell 新起一个shell
|21.3| Remembering information; viminfo 保存了
Command-line and Search pattern history
Text in registers
Marks for various files
The buffer list
Global variables
各种设置的限制，保存在 set viminfo 中
GETTING BACK TO WHERE YOU STOPPED VIM
退出之后，重新进入回到上一次工作位置
`0 回到那一行，那一列
'0 回到那一行行首
这些若干位置，倒排序依次为 `0 `1 `2 `3
也可以用 :marks 查看。实际上都是marks
GETTING BACK TO SOME FILE 回到某个文件
方法一： :oldfiles ，观察文件编号，然后用 :e #<2 或者 :split #<3 进行编辑
方法二： :browse oldfiles 输入需要查看的文件编号Enter
MOVE INFO FROM ONE VIM TO ANOTHER
保存和读取寄存器内容，可以实现跨instance 互通。use the ":wviminfo" and ":rviminfo" commands to save and restore theinformation while still running Vim. This is useful for exchanging registercontents between two instances of Vim
也可以用来为不同目的 purpose 设置不同viminfo，进行保存和读取
:wviminfo! ~/tmp/viminfo 此处 ! 表示强制覆盖
:rviminfo! ~/tmp/viminfo 此处 ! 表示 全部读取，如果不用感叹号，则仅采用未 set 的
|21.4| Sessions
创建 Create Session
:mksession vimbook.vim
restore session
:source vimbook.vim
start Vim and restore a specific session 启动Vim并打开特定Session。 The 'S' stands for
session
vim -S vimbook.vim
'sessionoptions' option 中的一些设置
blank keep empty windows
buffers all buffers, not only the ones in a window
curdir the current directory
folds folds, also manually created ones
help the help window
options all options and mappings
tabpages all tab pages
winsize window sizes
terminal include terminal windows
:wall "保存所有改写过的文件
:mksession! ~/.vim/secret.vim "保存当前Session
:source ~/.vim/boring.vim "读取boring session
UNIX AND MS-WINDOWS
如果需要频繁切换UNIX环境和windows环境，则应设置
:set sessionoptions+=unix,slash
windows可以较好地读取UNIX文本，反之不行。
Windows可以较好地理解 / 分割名字，UNXI不能很好地理解 \
SESSIONS AND VIMINFO
Session 不包括寄存器、书签和命令历史------ not the position of marks, contents of registers and the c ommand line history. You need to use the viminfo feature for these things.------这些保存在 viminfo中
|21.5| Views
session保存整个vim的外观，view保存单一窗口的属性
:mkview 1 "保存当前窗口
:loadview 1 "可以为一个文件配置不同的view设置， 以数字命名多达9个------windows下似乎权限问题，无法写入
另一个方法
save the view of the current file: >
:mkview ~/.vim/main.vim
You can restore it with: >
:source ~/.vim/main.vim
|21.6| Modelines
告知编辑器，对特定格式文件采取特定设置。
The 'modelines' option specifies how many lines at the start and end of the file are inspected for containing a modeline. To inspect ten lines: 设置文本首部或者末尾多少行之内，检查包含modeline
:set modelines=10
The 'modeline' option can be used to switch this off. Do this when you are
working as root on Unix or Administrator on MS-Windows, or when you don't
trust the files you are editing: >
:set nomodeline
设置的格式
any-text vim:set {option}={value} ... : any-text
Any-text 可以是任意文本，例如 注释符号 /* */
第二个冒号 : 之后的文本被忽略
例如
/* vim:set shiftwidth=4: */
