For example we have to files in the directory test.

// address.go
package models

import "fmt"

var (
	EmptyVariable, AnotherEmptyVariable string
	A, B                                = "1", 2
	PackageVariable                     = "Teststreet"
	AnotherPackageVariable              = "Anotherteststreet"
)

const (
	StartingStreetNumber = 1
)

type (
	AddressLike interface {
		FullAddress(withPostalCode bool) string
	}

	Address struct {
		A, B          string
		Street        string
		City          string
		PostalCode    string
		Country       string
		CustomChannel chan string
		AnInterface   *interface{}
	}
)

func (address Address) FullAddress(withPostalCode bool) string {
	return fmt.Sprintf(
		"%s %s %d",
		PackageVariable,
		AnotherPackageVariable,
		StartingStreetNumber,
	)
}

// user.go
package models

import "github.com/bykof/go-plantuml/test/address/models"

type (
	User struct {
		FirstName      string
		LastName       string
		Age            uint8
		Address        *models.Address
		privateAddress models.Address
	}
)

func (user *User) SetFirstName(firstName string) {
	user.FirstName = firstName
}

func PackageFunction() string {
	return "Hello World"
}

Then we run go-plantuml generate or go-plantuml generate -d . -o graph.puml.

This will create a graph.puml file and check for .go files inside your current directory.
