zachary @gparker The word "currently" has me worried, but, thats awesome.
%zd, %tu, %tx (signed, unsigned, hex) currently format NSInteger and NSUInteger with no warnings.

@gparker@kongtomorrow Where are those documented? Last I checked the Apple docs say cast to long. - View other replies

@eridius@gparker@kongtomorrow https://developer.apple.com/library/mac/documentation/Cocoa/Conceptual/Strings/Articles/formatSpecifiers.html … But, as@kongtomorrow says, no explicit mention of NSU?Integer. -
@boredzo@eridius@kongtomorrow NS[U]Integer happen to be the "corresponding [un]signed integer type" on all four OSX and iOS architectures. -
@gparker@boredzo@eridius@kongtomorrow Thanks. I'd been casting to long too.

@gparker what are the z and t modifiers? -
-
@stephentyrone@gparker ah, so it'll only work as long as NS?Integer aligns with those types then. I wonder if that would ever change.

@gparker Hadn’t occurred to me to use the ptrdiff_t sizes for that. Thanks. -
@gparker I can’t wait to see how many people hardcoded, say, struct sizes instead of using sizeof() or offsetof(). -
-
@gparker Is there a rule somewhere about what modifiers to use? Or should we assume sizeof(size_t)==sizeof(ptrdiff_t)==sizeof(NSInteger)? -
@gparker The first one is for ssize_t. Did you mean %td? -
@gparker Nahhh, just cast to unsigned long, much better practice -
“
@gparker: %zd, %tu, %tx (signed, unsigned, hex) currently format NSInteger and NSUInteger with no warnings.” Well, that's interesting. -
