Disable method evaluation inside template

I am using Go for template evaluation and the following is my use case.

We have our application in which we ask customers to include prefixed-based placeholders along with their text.

E.g.:

my name is {$.PRE.FIRSTNAME} 

This will be automatically replaced with their first name, this is just a simple text, there will be more complex text which will be entered by the customer. it can even be a HTML.

following is the code snippet

Over here the first templateText works perfectly file and the second commented one doesn't work. it throws an exception stating a function not defined.

package main

import (
	"bytes"
	"html/template"
	"log"
)

// OuterObject  object
type OuterObject struct {
	PRE *InnerObject
}

// InnerObject macro object
type InnerObject struct {
	FIRSTNAME, LASTNAME string
}

func main() {
	// This works perfectly.
	templateText := "my name is {$.PRE.FIRSTNAME}  "
	// templateText := "my name is {$.PRE.FIRSTNAME} ().push(function() { globalAml.display('sss') };"
	//
	// Above templateText fails with exception :
	// function "globalAml" not defined
	//
	o := &OuterObject{
		PRE: &InnerObject{
			FIRSTNAME: "fName",
			LASTNAME:  "lName",
		},
	}

	var doc bytes.Buffer
	t, err := template.New("test").Delims("{", "}").Parse(templateText)

	if err != nil {
		log.Fatal("Error parsing tag", err)
	}
	err1 := t.Execute(&doc, o)
	if err1 != nil {
		log.Println("Error Execute tag", err1)
	}
	log.Println("Final text ", doc.String())
}

Can anyone help me to ignore the method calls and just to replace the prefixed-based placeholders.

I was temporarily able to handle this case by changing the code snippet to following :

t, err := template.New("test").Delims("{$", "}").Parse(templateText)

I know this will fail in cases where customer entering a text containing these above delimiters.

Thanks a lot, guys.

Your second substitution fails because { and } are the template delimiters. You need to quote them to make this work:

templateText := "my name is {$.PRE.FIRSTNAME} ().push(function() {`{`} globalAml.display('sss') {`}`};"
