slime 20070503 Enhancement to support Emacs.app

[jrh@…]

Here is a Portfile patch to enable slime to use Emacs.app for compilation and as the installation destination (i.e. to use 'emacs-app' instead of 'emacs' as the depends_lib).

[jrh@…]

adds a variant to use emacs-app instead of emacs

[evenson@…]

A very much reworked version of the MacPorts SLIME portfile that:

* updates the sources to CVS HEAD of 20080203, which reflects the major

refactoring into a 'contrib' subdirectory that occured in the last couple of months

* now has an 'app' variant that will install with the 'emacs-app' port

* removed the obsolescent 'devel' variant ('emacs-devel' is no longer in the

MacPorts

* updated style to comply with what is outlined in http://guide.macports.org/#development.practices (no tabs, 4 column indents, Emacs/vim initial modeline)

* rewrote the sample '.emacs' initialization code message to conform with the new style enabling SLIME to more easily serve as the frontend to multiple Lisp (or with varying commandline options)

Additional cleanups before re-requesting commit:

* now works with 'emacs+carbon' by finding the correct Emacs binary

* if an Emacs binary is not found (should always but to be safe), don't bytecompile the *.el files

* disambiguate global variables by prepending 'slime_' to all of them

* cleaned up .emacs initialization code examples

* now passes port lint target

And

* update to CVS version 20080216 upstream

[evenson@…]

And * changed the dependency on installed Lisp so that '+sbcl' is now the default_variant

[jrh@…]

Replying to evenson@panix.com:

* now works with 'emacs+carbon' by finding the correct Emacs binary

The emacs+carbon fix breaks emacs-app support. That code needs to be moved into the else clause of if variant_isset app. Also, the app variant needs to modify depends_lib. Finally, #12115 is closed, so Emacs.app is now able to find slime in ${prefix}/share/emacs/site-lisp.

I'm attaching a modification of your Portfile.
