Go 调试插件

Go 插件调试

Go允许使用--buildmode=plugin在unix系统上编译插件，得到.so文件。

此时如果直接在VSCode中调用Delve调试插件，会报错：plugin.Open failed: plugin was built with a different version of package。

查阅VsCode-go的调试指南，发现local debug模式要求”The binary must be built with go build -gcflags=all=”-N -l” to disable inlining and optimizations that can interfere with debugging.”

故而我们需要在编译插件时，添加-gcflags=all="-N -l"参数（可通过launch config中的prelaunchTask调用编译任务实现）。

VSCode配置

launch.json和tasks.json的配置如下：

{
  "version": "0.2.0",
  "configurations": [
    {
      "name": "Launch main",
      "type": "go",
      "request": "launch",
      "program": "${workspaceFolder}/main.go",
      "args": [],
      "preLaunchTask": "build plugin"
    }
  ]
}

{
  "tasks": [
    {
      "label": "build plugin",
      "type": "shell",
      "command": "go build -gcflags=all=\"-N -l\" -o plugin.so -buildmode=plugin .",
      "group": {
        "kind": "build",
        "isDefault": true
      }
    }
  ]
}
