How set TEMPLATE_STRING_IF_INVALID

[iyaozhen]

My tpl is "t {{no_value}}" and not set no_value in context, it return "t ", now.

If a variable that doesn’t exist, I hope the template system will insert the raw token. e.g. "t {{no_value}}". It is useful for debug.

That's a feature not yet supported. I'll add it to the withlist.
