template.ParseFiles reading multiple files

[andersk (Anders Kristensen)]

I figured it out.

1. Read all files of different directories using ReadDir. Created a function:

    func GetTempFilesFromFolders(folders []string) []string {
   
    var filepaths []string
    for _, folder := range folders {
    	files, err := ioutil.ReadDir(folder)
    	CheckErr(err)
   
    	for _, file := range files {
    		if(strings.Contains(file.Name(),".html")) {
    			filepaths = append(filepaths, folder+file.Name())
    		}
    	}
    }
    return filepaths
    }
   

2. Use the string slice as variadic parameter: filepaths…

    tempfiles := funcs.GetTempFilesFromFolders(dirs)
    var temp_lp = template.Must(template.ParseFiles(tempfiles...))
