在linux下模拟win+arrow来左右半屏当前窗口

目的

用习惯了windows下的win+arrow来左右窗口，在linux觉得非常不方便的。
所以上网看一下在RHEL6上可以使用的方法。因为不想依赖compiz，所以找到的最好方法是xdotool.
虽然不太完美，但可以满足80%的需求了。

安装xdotool

有两种方法，一种是源码安装，一种是yum安装

源码安装

上面步骤失败了， 所以手工来拷贝

cp libxkbcommon.so libxkbcommon.so.0 libxkbcommon.so.0.0.0 libxkbcommon-x11.so libxkbcommon-x11.so.0 libxkbcommon-x11.so.0.0.0 /usr/local/li
cp xkbcommon /usr/local/include/ -rf

安装xdotools

git clone https://github.com/jordansissel/xdotool.git
cd xdotool && make && make install

安装后命令可以执行，但没有效果
所以只能直接安装，这有一个问题是需要root权限

---

yum直接安装

如果有root权限，那么上面的步骤都不需要，直接用yum安装就好

yum install xtodool

安装后是可以使用

---

绑定快捷键

一种是利用系统快捷键(推荐)，一种是利用xbindkeys(除了做这个其实可以做很多事)

使用系统快捷键

mkdir ~/.winarrow
echo '#!/usr/local/bin/zsh' > ~/.winarrow/leftarrow.sh
echo 'xdotool windowsize $(xdotool getwindowfocus) 50% 100% && xdotool windowmove $(xdotool getwindowfocus) 0 y' >> ~/.winarrow/rightarrow.sh
echo '#!/usr/local/bin/zsh' > ~/.winarrow/leftarrow.sh
echo 'xdotool windowsize $(xdotool getwindowfocus) 50% 100% && xdotool windowmove $(xdotool getwindowfocus) 9999 y' >> ~/.winarrow/rightarrow.sh

然后到系统快捷键里把win+left映射到/home/harriszh/.winarrow/leftarrow.sh, 把win+right映射到/home/harriszh/.winarrow/rightarrow.sh,

注意：直接把命令写在"custom shortcut"的command里不起作用， 因为这个命令里有$()命令替换

---

使用xbindkeys

安装guile

yum install guile

安装guile-config

从centos.pkgs.org下载包

rpm -Uvh /mnt/hgfs/ed/13_linux/gmp-4.3.1-12.el6.x86_64.rpm
rpm -ivh /mnt/hgfs/ed/13_linux/gmp-devel-4.3.1-12.el6.x86_64.rpm
rpm -ivh /mnt/hgfs/ed/13_linux/guile-devel-1.8.7-5.el6.x86_64.rpm

安装xbindkeys

./configura && make && make install

在home目录下vi ~/.xbindkeysrc
"xdotool windowsize $(xdotool getwindowfocus) 50% 100% && xdotool windowmove $(xdotool getwindowfocus) 0 y"

     Mod2+Mod4 + Left

"xdotool windowsize $(xdotool getwindowfocus) 50% 100% && xdotool windowmove $(xdotool getwindowfocus) 9999 y"

     Mod2+Mod4 + Right

然后添加到系统启动程序里

后言

xdotool的问题是窗口最大化时没法起作用（用alt+space,x来取消最大化），同时左停靠和右停靠时窗口上下没有最大。
希望后面的窗口管理器能自动集成这个功能，靠第三方工具是不太可能完美的
