What version of Go are you using (go version)?

$ go version
1.12.2 darwin/adm64

Does this issue reproduce with the latest release?

What operating system and processor architecture are you using (go env)?

go env Output
$ go env

What did you do?

template.Must(template.New("test").Funcs(newTempFuncs).ParseFiles("test.temp"))
will do nothing, seems that parsefiles does not suport funcs;

template.Must(template.New("test").Funcs(newTempFuncs).Parse(templatetest))
the templatetest has the some content as test.temp and works as expect...

if i change template.Must(template.New("test").Funcs(newTempFuncs).ParseFiles("test.temp")); to template.Must(template.ParseFiles("test.temp")) and remove funcs in tempfile, everythings seems fine...so I am confused...

What did you expect to see?

template.Must(template.New("test").Funcs(newTempFuncs).ParseFiles("test.temp"))
should render template

What did you see instead?

do nothing until i change to template.Must(template.ParseFiles("test.temp")) and work as expect

package main

import (
	"text/template"
	"os"
	"strings"
)

func main() {
	
	tmpl1 := template.Must(template.New("test").Funcs(template.FuncMap{"trim": strings.TrimSpace,}).ParseFiles("foo.tmpl"))
	
	tmpl1.Execute(os.Stdout, " string contains spaces both ")
}

foo.tmpl

{{.|trim}}
