New macro for the new feature of rb_scan_args()

Added by nobu (Nobuyoshi Nakada) about 11 years ago. Updated about 11 years ago.


Description

=begin
(({rb_scan_args()})) has new feature since 1.9.3, but there is no way to tell if it is available from extension libraries.
So we have to provide a preprocessor symbol for it now.

The name in my mind is (({HAVE_RB_SCAN_ARGS_OPTIONAL_HASH})) now.
Any ideas?
=end

Do you know any concrete application that is in urgent need of the information?

i for sample would like to know how to use the Optional Hash (and with 2.0 the default hash parameters) with rb_scan_args

Updated by nobu (Nobuyoshi Nakada) about 11 years ago

No concrete applications yet, but they will come soon certainly.

An extension library which wants to support optional hash may want to
use this feature, and the feature itself is intended to be.

Suppose that it wants to support 1.9.3 either right now, then it needs
the way to tell if rb_scan_args() supports ':'. But the way is now
only try_run, which can't work while cross compiling.

It's too late after the 2.0.0 release.
