libass: update to 0.12.2, port to GitHub

[Ionic (Mihai Moldovan)]

libass has seen newer versions for a while, but the port is currently stale at version 0.10.2.

Furthermore, the project switched to GitHub some time ago.

It is openmaintainer, but due to the changed being quite substantial, I'm not committing without asking the maintainer first.

Good thing I slept over it.

While waking up, I realized that the ASM parts will probably not work on ppc(64), so the port be broken for ppc(64) users.

Even worse, it turned out even i386 didn't compile correctly.

The new patch version fixes these problems (although I have only tested building on i386 and x86_64.)

Update libass to 0.12.2, port to GitHub. Updated to work universally.

+    if {[string match "*i386*" ${configure.universal_archs}] ||
+        [string match "*x86_64*" ${configure.universal_archs}]} {
+        depends_build-append port:yasm
+    }

You should use this instead:

if {"i386" in ${configure.universal_archs} || "x86_64" in ${configure.universal_archs}}

Are you sure that works? vim's syntax highlighting doesn't like it.

[larryv (Lawrence Velázquez)]

Vim’s Tcl highlighting is mediocre at best. I tend to ignore it.

[titan] 92134 % rlwrap port-tclsh
% set foo {x86_64 ppc64}
x86_64 ppc64
% expr {"x86_64" in $foo}
1
% expr {"i386" in $foo}
0
