Using function from `main` package into main.go file-CodePudding

I have 2 files into the root directory: main.go and utils.go.

main.go file is:

package main

func main() {
   CustomPrint()
}

utils.go file:

package main

import "fmt"

func CustomPrint() {
   fmt.Println("example")
}

However, I get an error because customPrint is not recognized.

Is there any way to do that without create another package to store utils.go file?

CodePudding user response：

yes. just build it with * wildcard. like this: go build *.go

CodePudding user response：

You can't have more than one main in your package. This can be implemented like:

main.go

package main

import (
    util "./utils"
)

func main() {
    util.CustomPrint()
}

/utils/utils.go

package utils

import "fmt"

func CustomPrint() {
    fmt.Println("example")
}
