How to Resolve Package Name Conflicts When Importing Multiple Packages in Go?

How to Handle Package Name Conflicts in Go

Importing packages with the same name can cause conflicts in Go source files. Consider a scenario where you need to use both the "text/template" and "html/template" packages within a single file.

The following code will result in errors due to name collisions:

import (
    "fmt"
    "net/http"
    "text/template" // template redeclared as imported package name
    "html/template" // template redeclared as imported package name
)

func handler_html(w http.ResponseWriter, r *http.Request) {
    t_html, err := html.template.New("foo").Parse(`{{define "T"}}Hello, {{.}}!{{end}}`)
    t_text, err := text.template.New("foo").Parse(`{{define "T"}}Hello, {{.}}!{{end}}`)

}

To resolve this conflict, you can import the packages under different names using the following approach:

import (
    "text/template"
    htemplate "html/template" // this is now imported as htemplate
)

Now, you can use "htemplate" to access the "html/template" package, while "template" refers to the "text/template" package, avoiding name collisions and enabling the usage of both packages within the same file.

Refer to the Go language specification for more details and best practices regarding package names and imports.
