自定义内置函数

4paradigm@4paradigmdeMacBook-Pro ~/P/j/copilot_operation (master)> pwd
/Users/4paradigm/Projects/judgeflow/copilot_operation前面前面的显示内容有点长,因此打算缩减下最前面的 user & hostname。
修改方式如下:
在命令行中输入 funced prompt_login,即可进入内置函数编辑状态。
> funced prompt_login
prompt_login> function prompt_login --description 'display user name for the prompt'
if not set -q __fish_machine
set -g __fish_machine
set -l debian_chroot $debian_chroot
if test -r /etc/debian_chroot
set debian_chroot (cat /etc/debian_chroot)
end
if set -q debian_chroot[1]
and test -n "$debian_chroot"
set -g __fish_machine "(chroot:$debian_chroot)"
end
end
# Prepend the chroot environment if present
if set -q __fish_machine[1]
echo -n -s (set_color yellow) "$__fish_machine" (set_color normal) ' '
end
# If we're running via SSH, change the host color.
set -l color_host $fish_color_host
if set -q SSH_TTY; and set -q fish_color_host_remote
set color_host $fish_color_host_remote
end
echo -n -s (set_color $fish_color_user) "$USER" (set_color normal) @ (set_color $color_host) (prompt_hostname) (set_color normal)
end将倒数第二行进行修改,修改后如下:
echo -n -s (set_color $fish_color_user) wangsc (set_color normal) @ (set_color $color_host) MacBook-Pro (set_color normal)最后输入 funcsave prompt_login 来保存脚本。

最后的效果如下:
