GoGo CodeLens

A VS Code extension that adds CodeLens annotations to your Go code. showing reference counts, interface implementations, and method relationships inline.

Features

Show reference count above function, interface, interface method, method, and struct in Go code
Show number of symbols implementing an interface or interface method
Show number of interfaces implemented by a method or struct
Fully customizable — You can enable/disable each annotation type and change how the codelens should be displayed

Interface	Method

Function	Struct

Don't worry, all annotations are fully customizable and can be turned off if you prefer a cleaner view.

Installation

Option 1: Install from VS Code Marketplace

You can download it from https://marketplace.visualstudio.com/items?itemName=xiaoxuxxxx.gogo-codelens

Option 2: Build and Install Locally

In case you don't trust my provided bundle vsix file (you should not trust any unknown extension in marketplace). Here's step to build

Prerequisite

NodeJS
vsce

Build extension file

install the dependencies

npm i

run build command

vsce package

and your .vsix file will be generated in workspace directory

Install from locally build file

From your VS Code, go to extension tab
Click ... and then click Install From VSIX
Select builded file

Tips: You can just drag and drop the .vsix file to the Extension tab to install it

Configuration

You can configure the extension in your VS Code settings.json or through the settings UI.
