vscode使用技巧

vs code是微软推出的一款开源免费的代码编辑器，可运行在Windows，Linux，MacOS平台，官方下载地址如下：

如果系统版本比较旧(如Ubuntu 16)，安装新版本vs code可能会出现出现一些问题，可以在下面链接下载旧版本：

1,安装插件

安装插件可以提高效率，可以参考我的安装：c/c++，python，DeviceTree，Makefile Tools，CMake。

2,快捷键

以Windows下为例：

• Ctrl + 鼠标左键单击：跳转代码;


• Alt + 左箭头：后退(返回跳转);


• Alt + 右箭头：前进(进入跳转);


• Alt + 上箭头：整行上移;


• Alt + 下箭头：整行下移;


• Alt + Shift + 上箭头：整行向上复制;


• Alt + Shift + 下箭头：整行向下复制;


• Shift + Del：剪切当前行(也可当作删除整行使用);


• Ctrl + A && Ctrl + K && Ctrl + F：格式化全选代码;


• Ctrl + K && Ctrl + T：切换主题；


• Ctrl + P：搜索文件;


• Ctrl + G：跳转到行;


• Ctrl + F：文件内搜索/替换;


• Ctrl + Shift + F：全局搜索关键字(折叠选项里可筛选搜索文件的范围，类型，及是否替换关键字);


• 如果安装了c/c++这个插件,那么多行注释可以这样写: 先输入双引号内的字符"/***/"，然后光标定位到倒数第一个"*"号之前，按下回车即可多行注释，范围内每一个回车自动新增注释一行;


• 目录树栏有个OUTLINE(中文名叫大纲)，可以查看函数目录;

3,内容定制

vs code面对大型代码工程时，在使用默认配置下，全局搜索和代码管理的效率非常低，我们需要调整配置，提高我们搜索和查看本地代码的效率，我们以Linux内核源码为例，在编译内核源码后，会产生大量的"*.o"的文件，这在全局搜索代码时，会拖慢我们找到代码的效率，除此之外，像"*.txt"，"*.md"，"*.rst"等文件，搜索时甚至大多数浏览代码时也不需要，我们就把它们屏蔽掉，下面是我针对全志一款芯片调整的Linux内核工程的vs code设置，首先在Linux内核根目录新建一个".vscode"，(注意前面的逗点)，在这个目录里新建两个json配置文件：c_cpp_properties.json和settings.json，分别写入如下内容:

c_cpp_properties.json

1 {
2 "configurations": [
3 {
4 "name": "Linux",
5 "includePath": [
6 "${workspaceFolder}/**",
7 "${workspaceFolder}/include/**",
8 "${workspaceFolder}/arch/arm/include/**"
9 ],
10 "intelliSenseMode": "linux-gcc-x64",
11 "compilerPath": "",
12 "cStandard": "c17",
13 "cppStandard": "c++17",
14 "configurationProvider": "ms-vscode.makefile-tools"
15 }
16 ],
17 "version": 4
18 }
