Takes a format string (char const*) and a list of tokens (Str) and returns a Str of the formatted string.
Tokens are provided in '<'identifier'>' format where '<' '>' are just angle brackets (you can change it in token_fmt_va)
---------------------------------------------------------
Example - A string with:
typedef <type> <name> <name>;
Will have a token_fmt arguments populated with:
"type", str_for_type,
"name", str_for_name,
and:
stringize( typedef <type> <name> <name>; )
-----------------------------------------------------------
So the full call for this example would be:
token_fmt(
"type", str_for_type
, "name", str_for_name
, stringize(
typedef <type> <name> <name>
));
!----------------------------------------------------------
! Note: token_fmt_va is whitespace sensitive for the tokens.
! This can be alleviated by skipping whitespace between brackets but it was choosen to not have that implementation by default.
