通过编译代码操纵Linux中的窗口大小？

发布于 2024-10-27 05:55:18 字数 402 浏览 3 评论 0原文

我使用 xrandr、grep 和 wmctrl 编写了几个脚本，将窗口最大化到屏幕大小的一半（以便轻松并排放置窗口），如下所示：

#!/bin/bash

w=`xrandr 2> /dev/null | grep '*' | grep -Po '\d+(?=x)'`
h=`xrandr 2> /dev/null | grep '*' | grep -Po '(?<=x)\d+'`
wmctrl -r :ACTIVE: -b remove,maximized_horz,maximized,vert
wmctrl -r :ACTIVE: -e 0,0,0,$((w / 2)),$h

有没有一种方法可以更原生地执行此操作？该脚本在我的台式机上运行良好，但在我的笔记本电脑上有半秒的延迟，这有点烦人。

I wrote a couple of scripts to maximize a window to half the size of the screen (to make it easy to place windows side-by-side) using xrandr, grep, and wmctrl as follows:

#!/bin/bash

w=`xrandr 2> /dev/null | grep '*' | grep -Po '\d+(?=x)'`
h=`xrandr 2> /dev/null | grep '*' | grep -Po '(?<=x)\d+'`
wmctrl -r :ACTIVE: -b remove,maximized_horz,maximized,vert
wmctrl -r :ACTIVE: -e 0,0,0,$((w / 2)),$h

Is there a way to do this more natively? The script works well on my desktop, but on my laptop there's a half-second lag that is kind of annoying.

测试代码

# w_h="$(print -- "1280x1024 0.0*" | awk '/.*\*$/{sub(/ .*$/, "");sub("x"," ");$1=$1/2 ;print}')"
# w="${w_h% *}" ; h="${w_h#* }"

实际代码

# awk matches only line ending with '*', remove everything from last space to EOL, replace X with " "
# w_H looks like "640 1040", below splits on space char populating correct var
w_h="$(xrandr | awk '/\*/{sub(/[0-9\.*\+]*$/, ""); sub("x", " "); $1=$1/2; print}')"
w="${w_h% *}" ; h="${w_h#* }"
wmctrl -r :ACTIVE: -b remove,maximized_horz,maximized,vert
wmctrl -r :ACTIVE: -e 0,0,0,${w},${h}

请注意，我已经在 awk 内完成了 W 上的 div。此外，反引号在 posix shell 中已被弃用。让您的生活更轻松，使用 $() 进行命令替换;-)

我希望这会有所帮助。

wmctrl -r :ACTIVE: -b remove,maximized_horz,maximized,vert
wmctrl -r :ACTIVE: -e 0,0,0,${w},${h}

Note that I have done the div on W inside awk. Also, backticks are deprecated in posix shells. Make your life easier and use $() for command substituton ;-)

I hope this helps.
