Re: Emacs on OS X development

This is perfect.

Yamamoto, is it easy to have an update of your 24.1 patches uploaded to FTP?  Incorporating this one and the one that you mailed out recently to the list?


After thinking about all the discussion here, and the rule that "every feature in Emacs should work in the GNU system, and should work at least as well in the GNU system as it does on any other platform" puts these "mac" patches in a predicament.  Things like animation support—that is taken care of mainly by the Cocoa libraries?—may not be easy to do well on the GNU system.  And it seems like, based on the bits I have read from Yamamoto, it would also not be easy to incorporate the "mac" changes into mainline because of fundamental design choices in the NS port.  But MacVIM is an example of this same problem dealt with by the Vim camp; it is an extension to Vim—by default support GTK and Gnome—and adds a nice Cocoa layer.

My only concern is that Yamamoto not get burnt out maintaing this; I don't know how time consuming it is but I assume there is some challenge. So the only question I have is if Yamamoto would consider keeping the source for his port in a VCS somewhere online so that people can help by submitting bugs and things. And maybe even build a small website to promote that version.  Maybe this would not be desirable for Yamamoto though, but it seems like it would build a bit more community for it, and also let people play with the HEAD version. Just an idea; I may have missed the discussion about this already...

And I believe no matter what the outcome, this is a win for all. More attention to Emacs on any platform will eventually trickle down to the GNU system in some way or another.  Maybe all the changes will get incorporated into the main tree or maybe none will, but I suspect the reality is a middle ground where some patches stay in the Mac port and some get the main tree.

I will try to work on creating .app binaries for this.  There has to be a simple way as someone is packaging Emacs.app now...
