Inline usage and implementation counts for Go files in VS Code — inspired by JetBrains Code Vision.
Features
- Usage counts — shows how many times a function or method is called, inline at the end of its declaration line
- Implementation counts — shows how many types implement an interface
- Clickable hints — click a hint to jump directly to the usage or open the references panel when there are multiple
Requirements
- The Go extension for VS Code must be installed and active (it provides the language server that powers symbol and reference lookups)
Extension Settings
| Setting | Default | Description |
|---|---|---|
goCodeVision.showUsages |
true |
Show usage count hints for functions and methods |
goCodeVision.showImplementations |
true |
Show implementation count hints for interfaces |
goCodeVision.debounceMs |
600 |
Delay in ms before refreshing hints after a file change |
How It Works
The extension uses VS Code's built-in InlayHintsProvider API together with the reference and implementation providers from the Go language server (gopls). After each file change (debounced), it queries all symbols in the document and fetches their references or implementations, then renders the counts as inlay hints.
