vscode如何配置C/C++环境，支持函数跳转和自动补全

Frankie

YUNTU所有的VSCODE工程编译都是基于CMake来实现的，所有可以很容易的被各个IDE/插件识别
VSCODE的C/C++插件可以用以下两种（任选其一即可），建议选择ClangD

clangd 插件

安装

安装clangd，vscode会默认下载clangd-server，或者可以手动选择clangd的目录

配置

clangd的配置是每个workspace下的*.code-workspace文件里单独配置

{
    "folders": [
        {
            "path": "."
        }
    ],
    "settings": {
        "clangd.arguments": [
            "--compile-commands-dir=${workspaceFolder}/build",
            "--query-driver=${env:APPDATA}/yt_config_tool/gcc-arm-none-eabi-10.3-2021.10/bin/arm-none-eabi-gcc.exe"
        ]
    }
}

其中 --compile-commands-dir 是必须的，clangd会默认去搜索这个目录下的 compile_commands.json 文件，这个文件是工程经过cmake编译后产生的一个文件，
格式大概如下：

{
  "directory": "C:/Users/Frankie/Downloads/ha0_dd/build",
  "command": "C:\\Users\\Frankie\\AppData\\Roaming\\yt_config_tool\\gcc-arm-none-eabi-10.3-2021.10\\bin\\arm-none-eabi-gcc.exe -DARMCM7_DP -DCORTEXM -DCPU_YTM32B1HA0 -DYTM32B1HA0 -IC:/Users/Frankie/Downloads/ha0_dd/board -IC:/Users/Frankie/Downloads/ha0_dd/platform/drivers/src/clock/YTM32B1Hx -IC:/Users/Frankie/Downloads/ha0_dd/platform/drivers/src/pins -IC:/Users/Frankie/Downloads/ha0_dd/platform/drivers/inc -IC:/Users/Frankie/Downloads/ha0_dd/platform/devices/common -IC:/Users/Frankie/Downloads/ha0_dd/platform/devices -IC:/Users/Frankie/Downloads/ha0_dd/platform/devices/YTM32B1HA0/include -IC:/Users/Frankie/Downloads/ha0_dd/platform/devices/YTM32B1HA0/startup -IC:/Users/Frankie/Downloads/ha0_dd/CMSIS/Core/Include -IC:/Users/Frankie/Downloads/ha0_dd/rtos/osif -mcpu=cortex-m7 -g -mlittle-endian -mthumb -specs=nosys.specs -Wall -Werror=all -Wno-error=comment -g -O1 -ffunction-sections -fdata-sections -Wno-error=unused-variable -Wno-error=unused-parameter -Wno-error=unused-function -Wno-error=unused-but-set-variable -Wno-error=unused-result -Wno-error=maybe-uninitialized -Wno-error=sign-compare -Wno-error=strict-aliasing -Wno-error=unknown-pragmas -Wno-error=format -fdiagnostics-color=always -o CMakeFiles\\GENERATED_CONFIG_TARGET.dir\\board\\clock_config.c.o -c C:\\Users\\Frankie\\Downloads\\ha0_dd\\board\\clock_config.c",
  "file": "C:\\Users\\Frankie\\Downloads\\ha0_dd\\board\\clock_config.c",
  "output": "CMakeFiles\\GENERATED_CONFIG_TARGET.dir\\board\\clock_config.c.o"
},

记录了每一个c文件的搜索路径，编写选项等信息。
--query-driver是可选测试，用于找到类似stdint.h 这种头文件，因为这些头文件在自己的工程下是不存在的。
配置好后，就可以进行跳转了。

效果

数组自动加入索引

函数参数名的显示

代码自动补全

C/C++ 插件

因为这个插件不是很推荐，所以就简单解释一下

安装

直接从vscode的扩展商店里安装即可

配置

c/c++的配置是每个workspace下的.vscode/c_cpp_properties.json文件里单独配置

{
    "env": {
        "PROJ_DIR": "${workspaceFolder}"
    },
    "configurations": [
        {
            "name": "YTM32B1HA0",
            "intelliSenseMode": "gcc-x64",
            "includePath": [
                "${PROJ_DIR}/board",
                "${PROJ_DIR}/platform/drivers/src/clock/YTM32B1Hx",
                "${PROJ_DIR}/platform/drivers/src/pins",
                "${PROJ_DIR}/platform/drivers/inc",
                "${PROJ_DIR}/platform/devices/common",
                "${PROJ_DIR}/platform/devices",
                "${PROJ_DIR}/platform/devices/YTM32B1HA0/include",
                "${PROJ_DIR}/platform/devices/YTM32B1HA0/startup",
                "${PROJ_DIR}/CMSIS/Core/Include",
                "${PROJ_DIR}/rtos/osif"
            ],
            "defines": [
                "YTM32B1HA0",
                "CPU_YTM32B1HA0"
            ],
            "cStandard": "c11",
            "cppStandard": "c++17",
            "compileCommands": "${workspaceFolder}/build/compile_commands.json",
            "browse": {
                "path": [
                    "${workspaceFolder}"
                ],
                "limitSymbolsToIncludedHeaders": true,
                "databaseFilename": ""
            },
            "configurationProvider": "ms-vscode.cmake-tools"
        }
    ]
}

也可以指定 compile_commands.json 文件

而且这两个插件貌似会有冲突

george 是的
