How to Resolve Conflicting Package Names When Importing Multiple Go Packages?

Importing and Utilizing Diverse Packages With Shared Names

When working with multiple packages containing identical package names, such as text/template and html/template, issues can arise while importing them within the same source file. Consider the following example:

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 ambiguity caused by the multiple declarations of template. To resolve this, we can utilize an alias while importing the conflicting package. Here's an example:

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

By assigning an alias (htemplate in this case), we can differentiate between the two packages and access their respective types and functions separately. In the above example, you can now utilize htemplate instead of html/template to interact with the HTML templating package.
