Global type override in .swaggo file not working

[bmpotter]

Describe the bug
First, thank you for this excellent swaggo project! It is a great productivity enhancement.

The replace statement in .swaggo does not seem to be honored for an external type. I can successfully use swaggertype for every use of that external type in all of my structs, but i want to be able to define the alternate type once in the .swaggo file instead.

To Reproduce
Use this main.go file:

package main

import (
	"fmt"
	"github.com/lib/pq"
)

type MyStruct struct {
	Foo    string         `json:"foo"`    // some field
	Labels pq.StringArray `json:"labels"` // external type not found in .swaggo file

	//Labels pq.StringArray `json:"labels" swaggertype:"array,string"` // this works
}

// @Router /myroute [get]
// @Summary Get something
// @id get
// @Tags MyStruct
// @Produce json
// @Success 200 {object} MyStruct "Resource returned"
func Get() {
	fmt.Println("getting something")
}

// @title My test case
// @version 0.1
// @tag.name MyStruct
func main() {
	fmt.Println("hello")
}

And use this .swaggo file:

// swag does not pick this up, still get msg: cannot find type definition: pq.StringArray
replace github.com/lib/pq.StringArray []string

// Also tried these:
// replace lib/pq.StringArray []string
// replace pq.StringArray []string
// skip github.com/lib/pq.StringArray

Then run $GOPATH/bin/swag init and you'll get this output:

Expected behavior
It should run without error, and in the generated docs/swagger.* files it should define the labels field as a string array.

Your swag version
The same problem occurs in both:
v1.7.8
v1.7.9-p1

Your go version
1.17.5

Desktop:
MacOS Big Sur 11.6

duplicate #1208

implemented in #1209 and you will be able to benefit from it in v1.8.4.

It works in v1.8.4, thx! This issue can be closed.

@bmpotter how did it work for you? I get

:cannot find type definition: []string

when I have replace pq.StringArray []string in .swaggo file
