Go Porject settings in VS Code

For now VS code is a great tool for develop Go project without much efforts to config. For most simple Go project you only need to install the Go plugin to turn your VS Code into Go IDE. I have noted some problems I have encountered when I setup Go in VS Code.

For the project using Go 1.11 Modules

It's a bit tricky to setup. Because we need set environment virable
GO111MODULE=on and build flag: -mod=vendor

// .vscode/launch.json for Go debug
{
    "version": "0.2.0",
    "configurations": [

        {
            "name": "Launch Package",
            "type": "go",
            "request": "launch",
            "mode": "debug",
            "program": "${workspaceFolder}",
            "env": {"GO111MODULE": "on"},
            "buildFlags": "-mod=vendor",
            "args": []
        }
    ]
}

Then you can run the Go project by clicking the debug button in vscode.
You can also change the .vscode/settings.json and add the go.buildFlags and go.toolsEnvVars .

For the go test, you can set go.testEnvVars and go.testFlags. But it does not work for the test for the project which forked from the original project. For this situation please check below article.

Disable 'format on save'

VS Code has enabled go format on save default. For most case, disable the go format on save is not recommended. But if you work on the legacy project or some project not put linter and format into workflow in the beginning. You may want to disable this feature.

It seems vscode-go or vscode have the bug with current version
Version 1.35.1 (1.35.1) go plugin version: 0.11.0
VS code can't disable "formatOnSave". And here is a alternative solution:

Open Shortcuts editor and change saveWithoutFormatting to
cmd+s and change save to cmd+k s:

{
  "key": "cmd+s",
  "command": "workbench.action.files.saveWithoutFormatting"
}

{
  "key": "cmd+k s",
  "command": "workbench.action.files.save"
}

And we should using below solution to achive this effect. But it's not working for current vscode.

The solution is to add this property to the .vscode/settings.json
May not work for Version 1.35.1 (1.35.1) go plugin version: 0.11.0

    "[go]": {
        "editor.formatOnSave": false
    }
