原文：Change cursor shape in different modes

不同终端版本修改代码不同。

使用如下命令查看Gnome-Terminal终端的版本：

aptitude show gnome-terminal

To change the shape of the cursor in different modes,you can add the following into your vimrc.

将不同版本终端对应的代码添加到vimrc文件中即可。

我的终端版本为3.18***，vimrc文件位于etc/vim/vimrc

For the Gnome-Terminal (version 2.26)Edit

This makes your cursor change in all open terminals. Upgrade your terminal and use the version above instead.

if has("autocmd")
  au InsertEnter * silent execute "!gconftool-2 --type string --set /apps/gnome-terminal/profiles/Default/cursor_shape ibeam"
  au InsertLeave * silent execute "!gconftool-2 --type string --set /apps/gnome-terminal/profiles/Default/cursor_shape block"
  au VimLeave * silent execute "!gconftool-2 --type string --set /apps/gnome-terminal/profiles/Default/cursor_shape ibeam"
endif

For the Gnome-Terminal (version 3.x)Edit

First make a script gnome-terminal-cursor-shape.sh

#!/bin/sh
DEFAULTPROF=`dconf read /org/gnome/terminal/legacy/profiles:/default`
DEFAULTPROF=`echo "$DEFAULTPROF" | sed -e "s/^'/:/" -e "s/'$//"`
dconf write /org/gnome/terminal/legacy/profiles:/$DEFAULTPROF/cursor-shape "'$1'"

Make it executable & put it in /usr/local/bin Next,add this to .vimrc

if has("autocmd")
    au InsertEnter *
        \ if v:insertmode == 'i' |
        \   silent execute "!gnome-terminal-cursor-shape.sh ibeam" |
        \ elseif v:insertmode == 'r' |
        \   silent execute "!gnome-terminal-cursor-shape.sh underline" |
        \ endif
    au InsertLeave * silent execute "!gnome-terminal-cursor-shape.sh block"
    au VimLeave * silent execute "!gnome-terminal-cursor-shape.sh block"
endif

If you use more than one profile in gnome-terminal,you might have to adapt this to your profiles.

For the Gnome-Terminal (version ≥3.16) Edit

This method has the advantage compared to the method above that it influences the given tab only,and not all the tabs that use the given profile. Add the following into .vimrc

if has("autocmd")
  au VimEnter,InsertLeave * silent execute '!echo -ne "\e[2 q"' | redraw!
  au InsertEnter,InsertChange *
    \ if v:insertmode == 'i' | 
    \   silent execute '!echo -ne "\e[6 q"' | redraw! |
    \ elseif v:insertmode == 'r' |
    \   silent execute '!echo -ne "\e[4 q"' | redraw! |
    \ endif
  au VimLeave * silent execute '!echo -ne "\e[ q"' | redraw!
endif

Above snippet disables cursor blinking. If you want cursor blink,just decrement all the 3 numbers above 2,4,6 by one each.

if has("autocmd")
  au VimEnter,InsertLeave * silent execute '!echo -ne "\e[1 q"' | redraw!
  au InsertEnter,InsertChange *
    \ if v:insertmode == 'i' | 
    \   silent execute '!echo -ne "\e[5 q"' | redraw! |
    \ elseif v:insertmode == 'r' |
    \   silent execute '!echo -ne "\e[3 q"' | redraw! |
    \ endif
  au VimLeave * silent execute '!echo -ne "\e[ q"' | redraw!
endif
