前言

以下是vscode的简单配置步骤,主要围绕.vscode文件夹的配置展开,由于网上对于VSCode的安装和MinGW的下载和环境变量的配置教程较多也很简单,本文不再赘述。

第一部分是.vscode文件夹的基础配置,使用此配置文件可以简单编译,运行和调试单文件和多文件的C语言程序,不能实现其他复杂任务

第二部分是.vscode文件夹的进阶配置,增加了C++的支持以及x86,x64以及debug和release模式的切换以及其他一些小功能

如有错误,欢迎指正:)

这是一些VSCode的快捷键以及配置文件时能用到的一些知识

Ctrl+Shift+P --- 打开命令面板

Ctrl+Shift+B --- 开始执行编译任务

调试相关快捷键:

F5 --- 启动调试/全速运行到下一个断点

Shift+F5 --- 停止

Ctrl+Shift+F5 --- 重新运行

F10 --- 单步跳过

F11 --- 单步进入

Shift+F11 --- 单步跳出

${workspaceFolder} --- 在VSCode中打开文件夹的绝对路径

${workspaceRoot} --- 在VSCode中打开文件夹的绝对路径+文件夹的名字

${workspaceRootFolderName} --- 在VSCode中打开文件夹的名字

${file} --- 文件自身的绝对路径

${fileBasename} --- 当前打开的文件名+后缀名(不包括路径)

${fileBasenameNoExtension} --- 当前打开的文件的文件名(不包括路径和后缀名)

${fileDirname} --- 当前打开的文件所在的绝对路径,不包括文件名

${fileExtname} --- 当前打开的文件的后缀名

${relativeFile} --- 相对于${workspaceFolder},当前打开的文件路径

${relativeFileDirname} --- 相对于${workspaceFolder},当前打开文件的目录名

${lineNumber} --- 当前文件光标所在的行号

.vscode文件夹基础配置

c_cpp_properties.json是用mingw编译的配置文件

下面是参考配置

{

"configurations": [

{

"name": "Win32",

"includePath": [

"${workspaceFolder}/**"

],

"defines": [

"_DEBUG",

"UNICODE",

"_UNICODE"

],

"windowsSdkVersion": "10.0.22621.0",

"compilerPath": "C:/mingw32/bin/gcc.exe",

//这里给出具体编译器位置,环境变量要提前配置好

"cStandard": "c17",//这里指定c语言标准

"cppStandard": "c++17",//这里指定c++标准

"intelliSenseMode": "linux-gcc-x86",

"compilerArgs": []

}

],

"version": 4

}

tasks.json是VSCode运行编译任务时的一些配置,要注意单文件和多文件的配置不同,

下面将分别给出说明

//单文件tasks.json

{

"version": "2.0.0",

"tasks": [

{

"type": "cppbuild",

"label": "C/C++: gcc.exe 生成活动文件",

"command": "C:/mingw32/bin/gcc.exe",

"args": [

"-fdiagnostics-color=always",

"-g",

"${file}",//这是要编译的文件名

"-o",

"${fileDirname}\\${fileBasenameNoExtension}.exe"

/*这是自动生成的原始配置,生成的exe文件在源文件所在的文件夹内

如果要保存在当前文件夹内的bin文件夹内,则改成

"${fileDirname}\\bin\\${fileBasenameNoExtension}.exe"*/

],

"options": {

"cwd": "C:/mingw32/bin"//这里依然是编译器路径

},

"problemMatcher": [

"$gcc"

],

"group": "build",

"detail": "编译器: C:/mingw32/bin/gcc.exe"

}

]

}

多文件编译要把所有文件放到一个文件夹内

.c/.cpp文件可以建一个src文件夹

.h文件可以建一个inc文件夹

//多文件tasks.json

{

"version": "2.0.0",

"tasks": [

{

"type": "cppbuild",

"label": "C/C++: gcc.exe 生成活动文件",

"command": "C:/mingw32/bin/gcc.exe",

"args": [

"-fdiagnostics-color=always",

"-g",

"${fileDirname}\\*.c",//当前路径下所有的.c文件

"${fileDirname}\\*.h",//当前路径下所有的.h文件

/*如果把.c和.h文件分到了src和inc文件夹,目前看来只能把

${fileDirname}换成具体的路径*/

"-o",

"${fileDirname}\\bin\\${fileBasenameNoExtension}.exe"

/*目前这样生成的.exe文件只能命名为选中源文件的名称(例如选中main.c

只能生成叫main.exe的文件),如果只单独打开这一个文件夹的话则无上述问

题,只需要改成

"${fileDirname}\\bin\\${workspaceFolderBasename}.exe"即可*/

],

"options": {

"cwd": "C:/mingw32/bin"

},

"problemMatcher": [

"$gcc"

],

"group": "build",

"detail": "编译器: C:/mingw32/bin/gcc.exe"

}

]

}

launch.json是VSCode的调试配置文件,如果没有在调试界面点击生成即可,进入

launch.json后右下角点击添加配置,选择gdb调试,自动生成模板后内容如下,单文件和多文件配置一致,因为都是生成一个exe文件

{

// 使用 IntelliSense 了解相关属性。

// 悬停以查看现有属性的描述。

// 欲了解更多信息,请访问: https://go.microsoft.com/fwlink/?linkid=830387

"version": "0.2.0",

"configurations": [

{

"name": "(gdb) 启动",

"type": "cppdbg",

"request": "launch",

"program": "输入程序名称,例如 ${workspaceFolder}/a.exe",

/*这是例子,需要按照具体情况修改

例如修改为${fileDirname}\\bin\\${fileBasenameNoExtension}.exe */

"args": [],

"stopAtEntry": false,

"cwd": "${fileDirname}",

"environment": [],

"externalConsole": false,

"MIMode": "gdb",

"miDebuggerPath": "/path/to/gdb",

/*这里是gdb路径,例如C:\\mingw32\\bin\\gdb.exe*/

"setupCommands": [

{

"description": "为 gdb 启用整齐打印",

"text": "-enable-pretty-printing",

"ignoreFailures": true

},

{

"description": "将反汇编风格设置为 Intel",

"text": "-gdb-set disassembly-flavor intel",

"ignoreFailures": true

}

]

},

}

基础配置不包含程序的运行,若要运行可以在VSCode中用PowerShell运行,但需要注意用powershell运行程序时必须先cd到该程序所在的文件夹(不能是父文件夹)不然会报错

.vscode文件夹进阶配置

x86和x64编译的切换

在c_cpp_properties.json中添加Win64编译选项``

{

"name": "Win64",

"includePath": [

"${workspaceFolder}/**"

],

"defines": [

"_DEBUG",

"UNICODE",

"_UNICODE"

],

"windowsSdkVersion": "10.0.22621.0",

"compilerPath": "C:/mingw64/bin/gcc.exe",

"cStandard": "c17",

"cppStandard": "c++17",

"intelliSenseMode": "windows-gcc-x64"

}

tasks.json中添加x64编译任务

{

"type": "cppbuild",

"label": "C/C++: gcc.exe 生成活动文件",

"command": "C:/mingw64/bin/gcc.exe",

"args": [

"-fdiagnostics-color=always",

"-g",

"${file}",//单文件编译,多文件搜索目录如下

//"${fileDirname}\\*.c",

//"${fileDirname}\\*.h",

"-o",

"${fileDirname}\\bin\\${fileBasenameNoExtension}.exe"

],

"options": {

"cwd": "C:/mingw64/bin"

},

"problemMatcher": [

"$gcc"

],

"group": {

"kind": "build",

"isDefault": false

},

"detail": "编译器: C:/mingw64/bin/gcc.exe"

}

debug和release的切换以及代码优化水平的设置

-g --- 用于生成调试信息,也就是debug模式

-O1 --- 代码优化水平1

-O2 --- 代码优化水平2

O1和O2都是属于release模式,代码优化水平O1

-o --- 指定输出文件名称,后面接要输出文件的路径和名称

debug时自动编译

在launch.json中加入"preLaunchTask":"build"

表示在调试前先执行编译任务,值与task中的label对应

默认启动项

在tasks.json中的group里加入"inDefault": true表示该task为默认项,只能有一个默认

task否则全部当非默认处理

build后直接run

在tasks.json中加入一个新任务,增加dependsOn: "build"和

"command": "${fileDirname}\\bin\\${fileBasenameNoExtension}.exe

其中"dependsOn"表示任务依赖,表示运行这个任务前要先执行build任务,也就是编译,名称和编译任务"label"值对应

"command"中执行exe文件,位置要与build任务中exe的生成位置相同

执行task时光标位置设定

在tasks.json的"presentasion"里添加"focus": true,表示在执行task时光标在终端,方

便进行输入,但对于build任务意义不大,在执行run任务时可以改为true

debug默认在main函数入口处停下

在launch.json中加入"stopAtEntry": true,相当于在main上打断点

中文乱码情况的解决

在args中添加"-fexec-charset=GB18030"使文件以GB18030编码

这里提一下GB2312,GB18030,GBK编码的区别

GB2312是第一个汉字编码的国家标准,GBK是GB2312的升级版,增加了更多的字符,而GB18030则是GBK的升级版,兼容Unicode编码,所以用GB18030更好

C++编译的两种方法

方法一:把原先的gcc换成g++就可以自动链接标准库

方法二:在C语言编译task的基础上,在args中加入"-lstdc++",这样就可以在用gcc编译时连接C++标准库,编译C语言也不受影响,值得注意的是"-lstdc++"在args中的位置,args是从上至下执行命令,"-lstdc++"不能在寻找源文件之前运行,否则会报错,所以添加在-o找到源文件之后

"args": [

"-fdiagnostics-color=always",

"-g",

"${file}",

"-lstdc++",

"-o",

"${fileDirname}\\bin\\${fileBasenameNoExtension}.exe",

"-fexec-charset=GB18030"

],

tasks.json中"presentation"设置详解

"echo" --- 该设置控制任务的输出是否在 VSCode 终端中显示。当设置为true时,任务输

出将显示在终端中;当设置为false时,任务输出将不显示在终端中

"reveal" --- 该设置控制任务输出是否在终端中打开。当设置为always时,每次任务运行

时,终端都会自动打开;当设置为silent时,终端不会自动打开,除非手动打开;当设置为never时,终端始终不打开

"focus" --- 该设置控制在任务运行时是否激活终端。当设置为true时,终端窗口将自动激

活;当设置为 false 时,终端窗口不会自动激活

"panel" --- 该设置控制任务输出是否与其他任务共享终端面板。当设置为shared时,任务

输出将与其他任务共享同一个终端面板;当设置为dedicated时,任务输出将在一个单独的终端面板中显示,不与其他任务共享
