Just FYI.... Emacs 22 has been a *long* time in coming, and is much
more functional and useful than Emacs 21 in many ways. This has
motivated various groups to roll out CVS pre-release versions, like
this one. There are even version which remap all key bindings to be
more "Mac-like" (see aquamacs.org).
Emacs 22 has at long last recently entered pre-test phase, so an
actual honest-to-goodness release will be coming soon. I'm attempting
to get IDLWAVE as up to date as possible for this release (since it
will be the default version people use for the next ~5 years). For
the first time, Emacs trivially compiles on OSX as either a Carbon
Emacs.app, or normal X11 Emacs (both have pluses/minuses w.r.t. IDL
usage). So, by all means install one of these "itchy trigger finger"
pre-release versions, but just make sure you get the latest "real"
version when it arrives hopefully soon. The magic version of IDLWAVE
to look for is 6.1_em22.
Easiest way to get going with Emacs is Help->Emacs Tutorial, and note that
in most Emacs mappings Meta == Apple (which is unfortunately different
from the default Terminal, where Meta == Option key). Also feel free to
ignore whatever seems weird and use whatever is easiest. For instance,
C-n for "down one line" is probably awkward for most people... just use
the down arrow, etc.
For the record, I actually prefer the X11 version of Emacs 22 on OSX,
because:
1. IDL is already running in X11, so you can switch back and forth using
focus-follow-mouse (if you like that kind of thing, and have set it
up).
2. On my Powerbook, I don't often have my external mouse handy, but
with X11, I can emulate 3-button mice using Apple and Option click
(and turn this off when I have my real bluetooth mouse available).
This isn't crucial, but many things in Emacs like other clicks
(middle-click to paste, right-click on IDL breakpoint lines to
change options, etc.).
3. I can make Option -> Meta (for uniformity) and Apple -> Super, so I
can save keystrokes by mapping IDLWAVE commands like C-c C-d C-c to s-c
(Super-c, aka Apple-c), etc. In ~/.emacs:
(setq idlwave-shell-debug-modifiers '(super))
On the other hand, Carbon Emacs has nicely anti-aliased fonts and benefits
from running its own applications (can hide it, use application-window
Expose, etc.).
