Concatenation of 2 strings in variables

[github-reader]

Hello I want to do this:

{{ $var1 := "val1" }}
{{ $var2 := "val2" }}
/* Wanted result, no valid gomplate code */
{{ $var3 := $var1 + $var2 }}

I have googled for a solution. It seems that gomplate cannot concatenate strings. How ca I solve that with gomplate? Hints to go language did not help. They also did not work here?

Hi @github-reader, I've moved this issue to a discussion instead as this is more of a question than a bug report.

There are a number of ways to concatenate strings in the Go templating language that gomplate uses. Usually, what I do is use the print keyword:

$ gomplate -i '{{ $var1 := "val1" }}{{ $var2 := "val2" }}{{ $var3 := print $var1 $var2 }}{{ $var3 }}'
val1val2

You can also use printf if you're familiar with that style of syntax:

$ gomplate -i '{{ $var1 := "val1" }}{{ $var2 := "val2" }}{{ $var3 := printf "%s%s" $var1 $var2 }}{{ $var3 }}'
val1val2
