[cream] Status Report on Mac Support for Cream

[Erik Z. <eri...@gm...>]

To summarize, I haven't been able to get it to run. Therefore I am
suggesting two solutions below.

The Mac port of gvim was withdrawn at some point in the past. MacVim is
typically used. MacVim is a fully functional version of gvim. It has the
added benefit of being compatible with the Mac clipboard, fully supporting
the Mac App functionality, and looking truly lovely on a Retina display.

Unfortunately MacVim does not accept the normal gvim startup arguments. It
is normally launched as a graphical app within Mac OS X. You can pass
startup arguments to it with the mac-unix open command, however MacVim is
either not expecting them, or is missing some extra step to support them.

***This prevents Cream from running on a Mac.***

Two separate but complementary things can be done to address this issue.

   1. (Out of scope for the Cream project — in scope for the MacVim
   project). Someone can fix MacVim to accept command line arguments, and
   hopefully make a “gvim” script alias that will pass that information along
   to MacVim.
   2. (In scope for Cream) Someone can produce a patch to the vim scripts
   that causes Cream to be used without any gvim command line arguments. This
   would consist of hard-coding the information that the cream startup command
   normally passes along to gvim. It would prevent gvim from being used
   without Cream, so it should be done in a way that makes it easy for someone
   to go in and disable it, by commenting out a single line for example.
   Especially if MacVim has further incompatibilities.

If someone knows of a way to patch the vim scripts as mentioned in item 2
above, then I would be excited to try it out. Has anyone done that before?

Thanks,
Erik
