vscode配置

vscode插件vim:esc和caps没切换，文件-首选项-设置，搜Keyboard:Dispatch改为keyCode重启软件即可

vscode调试C/C++

安装以下工具(本地调试直接本地安装，若远程调试就ssh之后在远程安装)

• vscode插件C/C++:C/C++ IntelliSense, debugging, and code browsing.
• vscode插件Cmake Tools:Extended CMake support in Visual Studio Code

系统ubuntu:

sudo apt install -y build-essential gdb cmake

系统arch:

sudo pacman -S base-devel gdb cmake

本地单文件调试

# zh @ li in ~/hello [20:14:03]
$ tree -a
└── hello.c

# zh @ li in ~/hello [20:15:03]
$ cat hello.c
#include <stdio.h>
#include <stdlib.h>

int main(int argc, char **argv)
{
    for(int i = 0; i < 2; i++){
        printf("hello world %d\n", i);
    }
    return 0;
}

运行-添加配置-C++(GDB/LLDB)-gcc(/usr/bin/gcc)，自动生成 launch.json 和 tasks.json 并进入调试(此时就可以打断点重新调试，在断点时，在调试控制台可以敲指令修改变量值等等的)

# zh @ li in ~/li/tmp/hello [21:39:07]
$ tree -a

├── hello.c
└── .vscode
    ├── launch.json #该文件用于调试
    └── tasks.json  #该文件用于编译

本地调试cmake项目

ctrl+shift+p-CMake:Select a kit可修改编译工具链(也可在状态栏点击修改或ctrl+shift+p-CMake:Edit User-Local Cmake Kits)

ctrl+shift+p-CMake:Select Variant可修改编译级别类型(也可在状态栏点击修改)

ctrl+shift+p-CMake:Configure配置项目

ctrl+shift+p-CMake:Build构建项目(也可在状态栏点击build)默认情况是构建所有目标，可以ctrl+shift+p-CMake:Set Build Target选择要构建的目标(也可以点状态栏)

设置断点过后，ctrl+shift+p-CMake:Debug即可开始调试(也可按F5)

远程调试

1. ssh-copy-id usr@ipaddr
2. vscode插件Remote-SSH:Open any folder on a remote machine using SSH and take advantage of VS Code’s full feature set.
3. vscode通过ssh登陆到远程
4. vscode搜索前面的插件，选择安装到远程
5. 打开项目，调试方式跟前面的一样
