Question

I am trying to dynamically parse files using walk in a folder and I want to be able to set the path of the file “path/file.html”. But my issue is if I have a file in a folder “path/folder/files.html” I can’t do it because when I ExecuteTemplate the file name will be the same “files.html”. Is it possible to name each template as I ParseFiles?

Im ok with doing a file one at a time if trying to do them all at once wont work.

// Parse file and send to responsewriter
func View(w http.ResponseWriter, path string) {
    temp, err := template.ParseFiles("application/views/"+path+".html")
    if err != nil {
        http.Error(w, err.Error(), http.StatusInternalServerError)
    } else {
        temp.ExecuteTemplate(w, path, nil)
    }
}

Walk the filesystem using filepath.Walk and a consumer method that will create templates with the full file paths as names:

package main

import (
    "fmt"
    "html/template"
    "os"
    "path/filepath"
)

func consumer(p string, i os.FileInfo, e error) error {
    t := template.New(p)
    fmt.Println(t.Name())
    return nil
}

func main() {
    filepath.Walk("/path/to/template/root", filepath.WalkFunc(consumer))
}
