Is there a “safeTemplateVariable” kind of function for Golang?
It is better to ask this question with an example:
First, lets declare a variable in Golang:
$html := "<b>hi!</b>"
If we try to output $html the output would be:
input: $html
output:<b>hi!</b>
If you pass the safeHTML function, the html will evaluate and the output would be:
input: safeHTML
output:hi!
Is there a way to parse a Golang variable? Like this:
If I try this: $var1 := "it's me!" $var2 := "hey guys, $var1 "
This would happen:
input: $var2
output:"hey guys, $var 1 "
But I want the $var1 value to be evaluated, like this:"hey guys, it's me!"
Sorry if I wasn't clear enough, I'm not a native english speaker
Thanks for the help!

"Safe" is the default mode for HTML templates in Go.
If you have a variable with special HTML characters, they are escaped on output, rendering them completely safe. This is different than stripping HTML tags, though, which your example seems to do. If you want to strip HTML tags, rather than escaping HTML characters, you'll need to write your own function.
If you want to disable safe behavior, and output raw HTML, use the template.HTML type.
