go-refs

Have you ever built a Go package which others depend on and need to understand how to best approach refactoring to limit breaking your external interface?

i.e. Do you need to know which exposed parts of your package are in use?

Go-refs uses Go's AST package to parse a (go) file and list any identifiers which are in use from a given import path.

Usage

go list -json ./... \
  | jq -r '.Dir + "/" + .GoFiles[]' \
  | xargs -n1 go-refs -pkg github.com/hashicorp/terraform/helper/schema \
  | sort | uniq -c | sort -nr
