hypr-cwd

#!/bin/sh
# 通过当前激活 window 的 title 获取当前的工作目录，
# 目前支持 emacs (需要配置 frame-title-format,如下文注释)
# 后续可以添加 alacritty/foot 等的支持(需要在 zsh/bash 中配置一定的规则以更新 window title)
# 可以实现的功能：
# 比如说 在 emacs 中 当前在/etc 目录下，我想打开 alacritty 终端并进入 /etc 目录，则可以使用以下命令
#  alacritty  --working-directory=$(hypr-cwd||echo $HOME)
# get current work directory of front most app
# supported app:
# 1. emacs
#       frame-title-format '( "%f  GNU/Emacs<" (:eval (expand-file-name default-directory)) ">")
#       详见：https://github.com/jixiuf/vmacs/blob/master/conf/conf-common.el#L56
# 2. alacritty with zsh
#       autoload -U add-zsh-hook
#       update_cwd(){
#           print -Pn "\e]2;$(pwd)\a" #s
#       }
#       add-zsh-hook precmd update_cwd
# bashrc
# tramp(){
#    printf "\e]2;/ssh:$(whoami)@$(ip addr | grep 'inet\b' |grep -v 127.0.0.1 | awk '{print $2}' | cut -d/ -f1):$(pwd)\a"
# }
