Overview Version History Q & A Rating & Review
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
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
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
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.
Caching Strategy
Setting
Description
Default
gogoCodeLens.codelens.cacheStrategyDefine the caching strategy when generating the codelens
VERSION_AND_TIMESTAMP
Possible Value
Description
VERSION_AND_TIMESTAMPCaches results based on the document version and the last updated dattime of all documents
NO_CACHEDisables 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
