7366 :: How to add a parameter based on a variable?

  I assume I would use a template somehow? If my_var == true then add a parameter, otherwise leave it out.

  My use case is Karax, where autofocus = "" must be added to an input() call to add autofocus functionality. I don't want to write an if/else block and duplicate my input() code.

  What's the default value of autofocus?

  I don't know, because Karax seems to generate code somehow, so there's no input proc to examine.

  Maybe make a helper proc using cstring(nil) as in Karax's toSelected/toDisabled/toChecked procs - https://github.com/pragmagic/karax/blob/4c06cb3204bfc89dbbdd1b4d20ca888bd61aeaa1/karax/karax.nim#L822
