I was just looking at the ghc port a few days ago, mostly in an attempt to figure out why it a-splode! on my 10.5 PPC system, and I noticed a lot of this:
platform darwin 7 powerpc { ... } platform darwin 8 powerpc { ... } platform darwin 8 i386 { ... }
And so on. It occurred to me that if "platform darwin 9 powerpc" (that's me) was going to duplicate a lot of the existing rules, maybe it would make more sense to introduce ranges and sets to the existing logic (I checked, and there's currently no support for it that a cursory glance indicated, anyway).
Then we could do stuff like this:
platform darwin [7-8] powerpc { ... }
platform darwin 9 {powerpc, i386} { .. }
And have far more concise portfiles. We might also have a platform_isset procedure so that you could do:
platform darwin [7-9] { if {[platform_isset darwin 8]} { .. do some special tiger-only magic .. } ... more darwin generic foo here ... }
Thoughts? If folks like the idea and nobody immediately jumps to do it, I might give the appropriate hacks a whack (eee! managers coding!).
That makes good sense to me, especially after looking at the ghc Portfile.
The gsl port seems to think this functionality already exists: platform darwin 6 7 { configure.cflags-append "-O1" } I wonder whether this section actually gets used on Panther or Jaguar...
