unexported

unexported

unexported provides a Go analyzer module. The analyzer is designed to check that exported functions and types use only exported types in their signatures. This helps to enforce best practices in Go code and ensures that the public API doesn't rely on unexported types.

Usage

go get github.com/la0rg/unexported

import "github.com/la0rg/unexported"

The unexported.NewAnalyzer() follows guidelines in the xanalysis package. This should make it easy to integrate unexported with your own analysis driver program.

Flags

The "unexported" analyzer supports the following flags:

• skip-interfaces: When set, interfaces are excluded from the analysis.
• skip-types: When set, types are excluded from the analysis.
• skip-func-args: When set, function arguments are excluded from the analysis.
• skip-func-returns: When set, function return parameters are excluded from the analysis.

Command-Line Tool

This repository also includes a command-line tool to run the "unexported" analyzer on your code. The tool can be found in the cmd/unexported directory. To use the tool, follow these steps:

1. Install:

go install github.com/la0rg/unexported/cmd/unexported@latest

1. Run the tool passing the path to your Go code:

unexported [flags] [packages]

Example

Given the package:

package storage

type person struct {
	Name string
}

func GetPerson() person {
	return person{Name: "John Doe"}
}

func SavePerson(p person) {
	// save to DB
}

type ExtendedPerson struct {
	Person person
}

running the unexported ./... command with the default flags will produce:

storage.go:7:18: unexported type person is used in the exported function GetPerson
storage.go:11:17: unexported type person is used in the exported function SavePerson
storage.go:15:6: unexported type person is used in the exported type declaration ExtendedPerson
