vscode 更换背景图片的 python 脚本

vscode 更换背景图片的 python 脚本

vscode 可以通过插件来实现更换背景图片，但是并不好看

还是要通过修改软件本身才能达到美观的目的

vscode 背景样式css文件的路径

win：盘符:\Users\用户名\AppData\Local\Programs\Microsoft VS Code\resources\app\out\vs\workbench\workbench.desktop.main.css

linux：/usr/share/code/resources/app/out/vs/workbench\workbench.desktop.main.css

修改的样式

好几个版本了，都没啥变动，就是workbench.desktop.main.css文件中的第5个body{(一共有14个)

如果workbench.desktop.main.css文件结构变了，代码是要重写的

因为权限的一些问题，需要把要替换的图片放到与workbench.desktop.main.css同级目录下

body {
    height: 100%;
    width: 100%;
    margin: 0;
    padding: 0;
    overflow: hidden;
    font-size: 11px;
    user-select: none;
    pointer-events: auto !important;
    background-size: 100% !important;
    opacity: 0.8 !important;
    background-position: 0 0 !important;background-image: url('xxx.jpg') !important;content: '';
    position:absolute;
    z-index:99999;
    width:100%;
    background-repeat: no-repeat;
}

这是为了方便展示，保存的话，还是建议缩进成1行

python脚本替换vscode背景

直接看代码吧，不是很复杂的脚本

路径写死了，可以替换，可以传参

暂且命名为 change_backgroud.py

如果workbench.desktop.main.css文件结构变了，代码是要重写的
