Access to html/template functions

[toqueteos]

I've tried to use the printf function but I just get panics:

#{printf "%s:%s" $a $b}
{{printf "%s:%s" $a $b}}

Are html/template builtin functions allowed somehow? If so, how?

Try using Go style function calls:

#{printf("%s:%s", $a, $b)}

@eknkc 👍 ❤️ Oh god, finally. Thaaaanks so much. Really. Best templating library to date.

P.D: You should mention this on the docs.

Thanks a lot!

You are right, there seems to be no mention about function calls on the documentation. Gonna put somthing.

Also another good addition is that pipelined functions don't work. Example:
{{fn 1 | printf}} -> #{fn(1)|printf}

I don't know if that's intentional or a consequence of the templating engine (char | is used for content delimiting).

Edit: Typo, pipelined functions instead of filters.
