Description Keith Rollin 2016-12-08 21:49:23 PST
As Alex noted in Bug 164527, Comment 40, the string specifications in format strings are not standard and don't build with non-Cocoa SDKs or even with Cocoa SDKs that are not recent enough.

I thought about using "PRIs" instead of "STRING_SPECIFICATION" (as an analog to "PRId8", et al), but wasn't sure everyone would get the reference. Also, I've been encouraged by multiple parties to spell out my symbol names, so I went with "STRING_SPECIFICATION". But if there's support for "PRIs" (or perhaps "PRIsPUBLIC"), I could use that instead.

We do use a lot of PRI* in places like NetworkCacheStatistics.cpp, but PRIs isn't standardized and I think this is indeed better.

http://www.cplusplus.com/reference/cstdio/printf/ calls this a "specifier" not a "specification".  Let's call them specifiers.  If they're called specifications somewhere I'm not familiar with, that's ok, too.
