For parsing files i have setup a variable for template.ParseFiles and i currently have to manually set each file.

Two things:

How would i be able to walk through a main folder and a multitude of subfolders and automatically add them to ParseFiles so i dont have to manually add each file individually?

How would i be able to call a file with the same name in a subfolder because currently I get an error at runtime if i add same name file in ParseFiles.

var templates = template.Must(template.ParseFiles(
    "index.html", // main file
    "subfolder/index.html" // subfolder with same filename errors on runtime
    "includes/header.html", "includes/footer.html",
))


func main() {
    // Walk and ParseFiles
    filepath.Walk("files", func(path string, info os.FileInfo, err error) {
        if !info.IsDir() {
            // Add path to ParseFiles


        }
        return
    })

    http.HandleFunc("/", home)
    http.ListenAndServe(":8080", nil)
}

func home(w http.ResponseWriter, r *http.Request) {
    render(w, "index.html")
}

func render(w http.ResponseWriter, tmpl string) {
    err := templates.ExecuteTemplate(w, tmpl, nil)
    if err != nil {
        http.Error(w, err.Error(), http.StatusInternalServerError)
    }
}
