How Can I Resolve Conflicting Package Imports with Identical Names in Go?

Understanding Import Declarations for Packages with Duplicating Names

To utilize multiple packages with identical names in the same source file, understanding import declarations is crucial. When importing packages with the same name, such as "text/template" and "html/template," conflicting declarations can arise.

Consider the following code:

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}}`)
}

This code will result in errors due to the redeclaration of the "template" variable. To resolve this issue, we can rename one of the packages using an alias. For instance:

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

By renaming "html/template" to "htemplate," we can access both packages separately. For example:

t_html, err := htemplate.New("foo").Parse(`{{define "T"}}Hello, {{.}}!{{end}}`)

This code will create a new template using the "html/template" package through the "htemplate" alias.
