Hi,
Yesterday I committed RubyCocoa support for the prinf_format XML
attributes in bridge support files. Something that I completely forgot
to work on.
What does that mean?
Before, RubyCocoa used to handle APIs accepting a format string and a
variable number of arguments in a quite stupid way, by converting all
the variable arguments after the format string as if they were
Objective-C objects (C_ID type).
So, NSLog('%d', 42) didn't work, because the Fixnum 42 was converted
into an NSNumber, and that %d expects a C integer.
With the new committed support, RubyCocoa will know all APIs that have
a format string argument, and at runtime it will parse the format
string in order to know which type the variable arguments should be
converted to.
NSLog('%d %s %f %@', 42, 'foo', 42.42, 42) will work as expected: 1st
will be converted as a C integer, 2nd as a C string, 3rd as a C
floating numeric and 4th as a NSNumber.
