I have just rehacked the C format hack as follows:
* you can now use format specifier S (capital S) for a
string argument
* you can now specify positions like
print$ f"%2$+10.3d --> %S\n" ("Hello",99);
The %99$ format is a common extension to C formats,
especially useful for i18n applications such as gettext
message catalogs (where language grammars dictate different
ordering of arguments in messages).
The position indicators work even if your C library
doesn't support them: they're handled by Felix directly.
Positions count from left to right for formats without
any specified position, that is, formats WITH a position
don't increment the count.
The position numbers are ONE origin .. even though Felix
numbers tuples ZERO origin (but Felix numbers $1, $2 arguments
for primitives ONE origin .. just to confuse you :)
* there's a lot more error checking of the formats now
* you cannot leave out an argument position
* You cannot use position specifiers for * specifiers
(this is a buglet)
