template.ParseFiles reading multiple files

[andersk (Anders Kristensen)]

Hello,

I am using template.ParseFiles to read files but the problem is the list of templates is going bigger day by day and I need all of them to be loaded.

I need to do something like:
var temp_pages = template.Must(template.ParseFiles("/temps1/*.html","/temps2/*.html")

/temps1/* == will read all the html files in temps1 folder
/temps1/* == will read all the html files in temps2 folder

I know I can use ParseGlob but using that I can access only one folder.

Thanks

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...))

Try something like this:

t, err := template.New("templ").ParseGlob(path + "/templates/*.html")

[le] I saw you already used ParseGlob.
