I was hoping that some of the local experts might like to offer some
critiques of some bits of my .emacs file that I suspect might be
accomplishable in better or more standard ways.
(global-set-key [(control m)] 'newline-and-indent)
I've had this first bit just about since I started with Emacs. It's
hard to believe that anyone at all would use C-j for this, as the
Emacs manual seems to suggest. It's only in text-mode that it
occasionally gives me unwanted indentation.
(defadvice open-line (around vi-style-open-line activate)
"Make open-line behave more like vi."
(beginning-of-line)
ad-do-it
(indent-according-to-mode))
This snippet is also of pretty ancient vintage. It used to be its own
function, but I recently recast it as advice. It also occasionally
gives me unwanted indentation, typically in text-mode.
(global-set-key [(control x) (control o)] 'other-window-delete-rest)
(defun other-window-delete-rest (arg)
"Goes to the next window with other-window, then makes that window
the only visible window. With a prefix argument, kills the current
buffer first."
(interactive "P")
(if arg (kill-buffer nil))
(other-window 1)
(delete-other-windows))
This one has been so useful it's hard to believe it's not built into
Emacs somewhere. I only recently discovered C-x 4 0, which does part
of the job that this command does, but I think this arrangement is
better overall.
(defvar recenter-fraction 0.33
"The recenter-proportionally advice will recenter the screen by
putting the current line this far down the window.")
(defadvice recenter (before recenter-proportionally activate)
(or (ad-get-arg 0)
(ad-set-arg 0 (truncate (* recenter-fraction (window-body-height))))))
Pretty self-explanatory. It generally seems to be more convenient for
me to see about twice as much below the current line as above.
