First, you will need to have your Go environment correctly configured. The path folder for your Go binaries must also be added to the environment variable $PATH in your operating system. Please, find below some guidelines on how to do that in your operating system:

• Windows,
• Linux,
• and macOS

Then, you will need to install the impler package as follows:

go get -u github.com/jiandahao/impler

Obs: make sure your $GOPATH/bin is in your $PATH so that you can access the impler binary.

for local installation:

npm i vsce -g
// remove `out/**` in .vscodeignore
// then do 
vsce package

then you will get a .vsix file:

vscode-go-impl-methods-0.0.0-development.vsix 

select and install the generated vsix file.

VS Code extension that automatically generates method stubs for Golang interfaces. Just inform the receiver and the interface. The extension will generate the method stubs.

  • // mt MyType
  • // mp *MyPointer
• Open the Command Palette
  • Ctrl+Shift+P (Linux and Windows)
  • Shift+Command+P (macOS)
• Look for Go: Implement Interface Methods

The extension is working, but there are a few things to improve. Any suggestions are welcomed. Please, feel free to contribute.
