配置VSCode开发环境

简述

之前都是使用Clion写代码, 只是写写题目, 只有单文件. 虽然有插件自动添加add_executable()语句到CMakeLists.txt里. 但Clion还是太臃肿了, 文件数量一多, 启动和索引就要非常久.

后来发现VSCode这个轻量级的编辑器, 但是它只是个编辑器, 要想真正成为Clion那样的IDE还得折腾一番. 为了和Clion无缝过渡, 我打算使用CMake+MSVC作为VSCode的工具链.

配置文件

自动添加`add_executable()`

.vscode/AddExecutable.ps1

param(
  [string]$WorkspaceRoot = $(throw "Parameter missing: -WorkspaceRoot [Workspace root]"),
  [string]$SrcDir=$(throw "Parameter missing: -SrcDir [Relative path to the source file]"),
  [string]$SrcName=$(throw "Parameter missing: -SrcName [Name of the source file]")
)

if ($SrcDir[-1] -ne '\') {
  $SrcDir = $SrcDir.Insert($SrcDir.Length, '\')
}
if ($WorkspaceRoot[-1] -ne '\') {
  $WorkspaceRoot = $WorkspaceRoot.Insert($WorkspaceRoot.Length, '\')
}

if (!(Test-Path ($WorkspaceRoot + $SrcDir))) {
  throw "$($WorkspaceRoot + $SrcDir) doesn't exist!"
}

if (!(Test-Path ($WorkspaceRoot + $SrcDir + $SrcName))) {
  throw "$($WorkspaceRoot + $SrcDir + $SrcName) doesn't exist!"
}

$SrcNameWithoutExtention = $SrcName.split('.')
if ($SrcNameWithoutExtention.Length -ge 2) {
  $SrcNameWithoutExtention = $SrcNameWithoutExtention[0..($SrcNameWithoutExtention.Length - 2)]
} else {
  $SrcNameWithoutExtention = $SrcNameWithoutExtention[0]
}

$SrcNameWithoutExtention = $SrcNameWithoutExtention -join '_'
$ExecutableName = ($SrcDir + $SrcNameWithoutExtention) -Replace "\\", "_"
echo $("Executable name: " + $ExecutableName)
echo $("Source name without extention: " + $SrcNameWithoutExtention)

Add-Content -Path "$($WorkspaceRoot + $SrcDir)\CMakeLists.txt" -Value "`nadd_executable($ExecutableName $SrcName)" -Encoding "utf8" -NoNewline

.vscode/tasks.json

{
  "version": "2.0.0",
  "tasks": [
    {
      "type": "shell",
      "label": "Add Executable",
      "command": "./AddExecutable.ps1",
      "args": [
        "${workspaceFolder}",
        "${relativeFileDirname}",
        "${fileBasename}",
      ],
      "options": {
        "cwd": "${workspaceRoot}\\.vscode"
      },
      "problemMatcher": [
        "$msCompile"
      ],
      "group": {
        "kind": "build",
        "isDefault": true
      },
    }
  ]
}

打开某个*.cpp文件后, 按下Ctrl + Shift + B选择Add Executable, 即可在CMakeLists.txt文件看到add_executable()语句了.

其实安装C/C++ Compile Run插件更方便...
