GoGo CodeLens

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

What's new

• Added type alias, constant and variable codelens
• Added an option to choose the caching strategy.

See full changelog here https://github.com/XiaoXuxxxx/gogo-codelens/blob/main/CHANGELOG.md

Features

• Show reference count or implement count above function, interface, interface method, method, struct, type alias, constant, variable in Go code
• Fully customizable — You can enable/disable each annotation type and change how the codelens should be displayed

Interface	Method
Function	Struct
Type alias	Variable
Constant

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

1. install the dependencies

npm i 

2. run build command

vsce package

and your .vsix file will be generated in workspace directory

Install from locally build file

1. From your VS Code, go to extension tab

2. Click ... and then click Install From VSIX

3. 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.

Caching Strategy

Setting	Description	Default
gogoCodeLens.codelens.cacheStrategy	Define the caching strategy when generating the codelens	VERSION_AND_TIMESTAMP

Possible Value	Description
VERSION_AND_TIMESTAMP	Caches results based on the document version and the last updated dattime of all documents
NO_CACHE	Disables caching, forcing recalculation every time the file is switched or edited.

If you notice that the CodeLens is not updating correctly or behaves inconsistently, it may be due to caching issues. To resolve this, consider using NO_CACHE
