consistentimports: detect inconsistent import aliases

go-recipes Go Report Card OpenSSF Scorecard codecov

Report import paths and aliases count when same import path has multiple aliases.

go install github.com/nikolaydubina/consistentimports@latest
consistentimports ./...

In example bellow same same import has two alises passInspect != passinspect. This linter detects that.

// apple.go
import (
    passInspect "golang.org/x/tools/go/analysis/passes/inspect"
)

// pear.go
import (
    passinspect "golang.org/x/tools/go/analysis/passes/inspect"
)

Example

-: "k8s.io/utils/net" netutils:4 netutil:1
-: "k8s.io/client-go/listers/core/v1" corelisters:1 listersv1:1 v1listers:1
-: "k8s.io/client-go/informers/core/v1" coreinformers:1 informers:1
-: "k8s.io/api/rbac/v1" rbacv1:4 v1:2
-: "k8s.io/apimachinery/pkg/runtime" runtime:3 kruntime:1
-: "k8s.io/api/imagepolicy/v1alpha1" imagepolicyv1alpha1:1 v1alpha1:1

Alternatives

Appendix A: packages in same module

As of 2023-06-08, there seem to be no way to in golang.org/x/tools/go/analysis to:

However, for practical use we really need to narrow down to current module, or else linter will keep checking recursively way outside of current module.

One simple heuristic is to check that package and the package it imports match long enough prefix.
