cperl printf indentation

cperl printf indentation

[Dan Jacobson]

Should hitting tab on each line in cperl mode really indent like this?:
    printf "%.1f\t%.1f\t%s\n",
      $F[0] - $C - $A * $F[0] - $B * $F[1],
	$F[1] + $D - $A * $F[1] - $B * $F[0],
	  "@F";

Well, there must be something else at work in
http://jidanni.org/geo/taiwan_datums/programs/twd6797thl
when you hit TAB on those lines.

Yes, probably - which emacs, cperl-mode file, and with what
settings in your .emacs are you using?

( Also note: if you load perl-mode after loading cperl-mode,
  it pretty much destroys cperl-mode's ability to function:
  to avoid this, I generally have (defalias 'perl-mode 'cperl-mode)
  in my .emacs )

cperl-version's value is "4.23"
# dlocate cperl-mode
emacs21-common: /usr/share/emacs/21.3/lisp/progmodes/cperl-mode.elc
# apt-cache policy emacs21-common
  Installed: 21.3-2

In http://jidanni.org/comp/emacs.txt I use fset. Should I use defalias instead?

OK, bug has been found. I will CC those concerned.

(I think you mean you want me to use printf() instead of printf.)
