vim的高级用法:退出vim时自动保存当前vim窗口的状态

用vim编辑文档时,我们经常会在同一个vim中同时打开几个文档在不同的窗口中并且会定义一些marks和在registers里面存储一些内容. 当我们退出vim后,这些信息大部分丢失了,特别是当我们重新打开文件后,原来打开的多窗口不会恢复,我们只打开了一个当前文件窗口. 由于vim强大的功能,我们想能不能在打开文件时,完全恢复原来退出时的状态, 就象我们没退出过一样.包括marks和registers都没被改变.答案是 可以.下面就列出来我是怎么修改vim的配置达到目的的 :

在你的 /etc/vim/gvimrc或/etc/vim/gvimrc.local中加入一下两行:

au VimLeave * mksession! ~/.vim/session/%:t.session
au VimLeave * wviminfo! ~/.vim/session/%:t.viminfo

并保证 目录~/.vim/session存在.

然后写一个脚本程序gvims:
#!/bin/sh
if [ -r ~/.vim/session/$1.session ]; then
gvim "+source ~/.vim/session/$1.session" "+rviminfo ~/.vim/session/$1.viminfo"
else
gvim $1
fi

当用gvim编辑完后,退出是,文件是以当前子窗口的名字保存窗口信息的,所以下次打开时,要用那个窗口名字作为gvims的参数.

这样的话, 对于一个项目的编辑非常有用. 例如: 我们现在做一个项目,名字是storm. 我们切换到项目storm所在的目录,运行 gvims storm. 这样就会打开一个gvim窗口,然后我们用 命令 :new storm.c 回车, 然后有输入命令 :vert new storm.h. 然后调整窗口大小,编辑,保存. 现在我们这个gvim窗口里有三个子窗口,一个显示storm, 一个显示storm.c,一个显示storm.h. 这时,我们切换到storm的编辑窗口,然后我们输入命令 :qa 退出gvim. 过了几天,我们可能要重新编辑项目storm,这是 你在任一个目录下(不一定是 项目storm的目录), 输入shell命令
gvims storm (如果你还记得你的项目名字是storm的话 (= ). 当gvim运行后,你会发现你的gvim显示的状态就象你几天前没退出一样. enjoy!

Improve it again. Now, it's more comfortable.

au VimLeave * exe ' if strlen(v:this_session) | exe "wviminfo! " . v:this_session . ".viminfo" | else | exe "wviminfo! " . "~/.vim/session/" . g:myfilename . ".session.viminfo" | endif '
au VimLeave * exe 'if strlen(v:this_session) | exe "mksession! " . v:this_session | else | exe "mksession! " . "~/.vim/session/" . g:myfilename . ".session" | endif '

script gvims:
#!/bin/sh
if [ -r ~/.vim/session/$1.session ]; then
gvim "+source ~/.vim/session/$1.session" "+rviminfo ~/.vim/session/$1.session.viminfo"
else
gvim "+let g:myfilename = \"$1\" "
fi

If we start with a project named "storm", just enter the command "gvims storm", then gvim will open a empty window.
Do what you want to do in gvim. If you have to stop your work for some reasons, just type ":wa", then ":qa" and leave.
When you want to continue your work sometime later, just enter "gvims storm". Everything is restored.

In addition, using "g:myprojectname" instead of "g:myfilename" above should be more better !
enjoy !

The scripts above is optimized to avoid the conflict between gvim and gvims.

in gvimrc or gvimrc.local
au VimLeave * exe 'if exists("g:cmd") && g:cmd == "gvims" | if strlen(v:this_session) | exe "wviminfo! " . v:this_session . ".viminfo" | else | exe "wviminfo! " . "~/.vim/session/" . g:myfilename . ".session.viminfo" | endif | endif '
au VimLeave * exe 'if exists("g:cmd") && g:cmd == "gvims" | if strlen(v:this_session) | exe "mksession! " . v:this_session | else | exe "mksession! " . "~/.vim/session/" . g:myfilename . ".session" | endif | endif'

#!/bin/sh
if [ -r ~/.vim/session/$1.session ]; then
gvim "+source ~/.vim/session/$1.session" "+rviminfo ~/.vim/session/$1.session.viminfo" "+let g:cmd = \"gvims\" " "+command Noprj let g:cmd = \"\" "
else
gvim "+let g:myfilename = \"$1\" " "+let g:cmd = \"gvims\" " "+command Noprj let g:cmd = \"\" "
fi


Vim/Gvim is greate !
