[go-nuts] Re: template Funcs with ParseFile and Execute

[Lee McLoughlin]

Perhaps I'm missing something in the documentation but I think this shows 
something odd happening when the name in New() and the first filename in 
ParseFiles() do not match:

package main

import (
        "fmt"
        "html/template"
        "log"
        "os"
)

// x.tpl contains just one line: hello

func main() {
        // Works
        {
                tpl := template.New("x.tpl")

                tpl, err := tpl.ParseFiles("x.tpl")
                if err != nil {
                        log.Fatal("parse ", err)
                }
                fmt.Println(tpl.DefinedTemplates())
                err = tpl.Execute(os.Stdout, nil)
                if err != nil {
                        log.Fatal("exec ", err)
                }
        }

        // Execute fails because template is "incomplete or empty"
        // The only difference is the name passed to New() "y" does NOT 
match
        // the file name passed to ParseFiles() "x.tpl"
        {
                tpl := template.New("y")

                tpl, err := tpl.ParseFiles("x.tpl")
                if err != nil {
                        log.Fatal("parse ", err)
                }
                fmt.Println(tpl.DefinedTemplates())
                err = tpl.Execute(os.Stdout, nil)
                if err != nil {
                        log.Fatal("exec ", err)
                }
        }
}
