Okay, i've apropos'ed, checked the manual, browsed my local sources, and looked through the elisp archives, and i still haven't found a solution: any suggestions for how to sort a dired buffer by _date_? Seems a little tough on the surface, since sort-columns appears to use a sort utility which won't do month names properly: i could have sworn i saw some code to do this before, but since i can't find it, if you've got a solution, please post/mail. ........................................

It's sort of a hack, but it works. The "s" key in the dired keymap is defined to call "dired-sort", which toggles the arguments to ls(1) between their normal dired value and a set which sorts by date. Each time you press the "s" key the arguments are toggled, ls(1) is called, and the results displayed. The ls(1) arguments are local to each dired buffer.

In the spirit of the recently posted dired-by-date patch, I seem to remember that it used to be that when you did M-x grep, and got your results in the *compilation* buffer, that hitting 'e' or somehing on a partiucular line would cause that file to be edited, and move the cursor to the line in question (One could even do this by character - enough information is present). Does someone still have the code which does this, or could perhaps some FSF member dig it out of the code locker? ceb

After grep or compile you can edit the files mentioned in *compilation* by
keying in C-x `. Every time you do this, you get into the next file.

? The following works on my machine:
Hmmmm. This seems to sort on the userid. Perhaps you have a weird ls?
And you have to use it all the time. It should be a separate function.
Not to be outdone, here is my version, simpler and more general:
Add the following to your .emacs to sort by both time and date:
(setq dired-mode-hook 'dired-mode-hook)
(defun dired-mode-hook ()
"Define dired extensions"
(setq case-fold-search t) ; Why is this not done?
(define-key dired-mode-map "t" 'dired-sort-by-time)
(define-key dired-mode-map "s" 'dired-sort-by-size)
(setq dired-mode-hook nil))
(defun dired-sort-by-time (arg) ; t
"Reread directory and sort by time. Reverse sort with prefix."
(interactive "P")
(let ((dired-listing-switches
(concat dired-listing-switches "t" (and arg "r"))))
(revert-buffer)))
(defun dired-sort-by-size (arg) ; s
"Reread directory and sort by size. Reverse sort with prefix."

In the spirit of the recently posted dired-by-date patch, I seem to

results in the *compilation* buffer, that hitting 'e' or somehing on a
partiucular line would cause that file to be edited, and move the
cursor to the line in question (One could even do this by character -
enough information is present).
Does someone still have the code which does this, or could perhaps
some FSF member dig it out of the code locker?
This isn't the old code (I wasn't aware of the old code) but it does
part of the trick:
;;; Added functions to the compile package
(defun ag-reparse-compilation-errors ()
"Move to a position in the compilation window,
skipping stuff you don't want,
and recreate list.
INTERIM: maybe long delay since whole list is redone.
but so far I have found it tolerable"
(interactive)
(compilation-forget-errors)
(save-excursion
(set-buffer "*compilation*")
(setq compilation-parsing-end (point)))
(next-error))
(make-global-binding "\^x\\" 'ag-reparse-compilation-errors)
As I mention inline, it can be slow since it reparses the *compilation*
buffer -- this was right for me, since I occasionally edit the compilation
buffer, but it isn't always the best. Or, you could move down the already
parsed list of marks until you found the one corresponding to your
position in the *compilation* buffer.
PS. is there any way, macro invocation or such, so that the docstring
can be split up into several lines and properly indented?
Eg. instead of:
(defun foo ()
"Multi
line
docstring
obscures
indentation"
(bar
(baz)))
Something like:
(defun foo ()
(CONCAT-MACRO
"Multi\n"
"line\n"
"docstring\n"
"reasonably\n"
"indented\n")
(bar
(baz)))
ANSI C combines adjacent string literals, separated by whitespace
including newlines, into one literal, but this obviously wouldn't
work for LISP.
I'm told that Common Lisp has a special code that indicates
to delete leading whitespace per line in the following literal,
but that's pretty ugly.
A macro would be what I want, but it seems that special forms
get in the way.
