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)
}
}
}
