Try using cperl-mode, rather than perl-mode. It's a much

You can always to C-q TAB to insert a literal tab. Depending on
programming modes, you have to find the relevant variable to get
them not to do syntax-driven indentaton.

M-x customize-variable RET tab-stop-list RET
If you change this and then save your changes, tab-stop-list
will be set.

How do I set that mode?
Why are there two perl modes? Why not just one?
Why is the broken perl mode the default? Why not make the good one the
default?

Well, what I'd actually like from an editor would be partial syntax-driven
inedentation. That is, hitting tab once puts the tabs where emacs thinks
they outght to be, and subsequent tab requests bump everything over one
tab. I'd also love it if there was *never* a time when I hit a button and
nothing happens.

And I'll have to do this on every host, right? There's no way to have a
single emacs config file to serve a whole network?

I have just tried the above with `emacs-21.3 -q --no-site-file' and couldn't
reproduce your problem. The ($o_year...) lines gets properly indented
below the previous line.
Could you show us a more complete example where the problem can be
reproduced ?

PS: Yes, the default perl-mode is not as sophisticated as cperl-mode.
Note that the version in the Emacs repository is significantly improved
in some areas (provided you use font-lock).

The easiest way is to add (defalias 'perl-mode 'cperl-mode) to
your ~/.emacs. The, any subsequent attempts to turn on
perl-mode, will use cperl-mode instead.
> Why are there two perl modes? Why not just one?
cperl-mode was originally an extra package not integrated into
Emacs. I'm not sure why it isn't the default now that it is
there.

(defun my-tab (&rest args)
"If `last-command' was `my-tab', insert a literal tab.
Else call `indent-according-to-mode'"
(interactive "P")
(if (eq last-command 'my-tab)
(save-excursion (beginning-of-line) (insert ?\t)) ; tab
(indent-according-to-mode)))
You might need to alter this somewhat to deal with indenting
blocks. Add this to your ~/.emacs, then, you can bind it in the
various modes you use. E.g., for cperl-mode, you'd do:
(add-hook 'cperl-mode-hook
#'(lambda ()
(define-key cperl-mode-map (kbd "TAB") #'my-tab))
Note that you need to define the key after loading cperl-mode,
otherwise your binding will be overriden by cperl's default one.

Depends on how you can access the files on the network.
Typically your ~/.emasc resides in your home directory. If this
isn't the same across the network, you'd have to copy the file
around to all the hosts. Or, and this gets slightly
complicated, write one complete .emacs, store it somewhere that's
accessible by (say) ftp, then, on each individual host, have a
minimal .emacs that `load's said file. Emacs has builtin support
for accessing ftp files. Look for documentation on ange-ftp for
how to use it.
Hope that sort of helps.

Well, that shouldn't be so hard to hack up. See the variable
`last-input-event'.

I keep mine in CVS (along with the rest of my dotfiles). This seems to

[root@bugzilla PhoneStats]# emacs --version
GNU Emacs 21.2.1 Copyright (C)
Ok, I have this astonishingly annoying problem in perl mode. I can't get
proper indention on some lines. Check this out:
------------
if(defined($rqpairs{'area'})) {
print "Content-type: text/html\n\n";
print "<html>";
print "<head><title>Canvassing report: $rqpairs{'area'}</title></head>\n";
print "<body bgcolor=white>";
print "Canvassing report for $rqpairs{'area'}<br>";
$dbcmd = "SELECT count(*) FROM calls WHERE ( (outgoingnum like ";
$dbcmd .= "'P1$rqpairs{'area'}%') OR (outgoingnum like 'P0";
$dbcmd .= "$rqpairs{'area'}\%')) ";
($year, $month, $day) = Date::Calc::Today();
($o_year, $o_month, $o_day) = Date::Calc::Add_Delta_Days($year, $month,
$day, -\
30);
$dstr = sprintf("'%04d-%02d-%02d' AND '%04d-%02d-%02d'",
$o_year, $o_month, $o_day, $year, $month, $day);
$dbcmd .= "AND (calldate between $dstr) ORDER BY calldate;";
$sth = $dbh -> prepare($dbcmd);
$sth->execute;
$count = $sth->fetchrow_array;
---------
Now, notice how the indention changes unexpectedly after the line
($year, $month, $day) = Date::Calc::Today();
This is also the first line where the :: notation is used. Is emacs unable
to understand this _extremely_ common notation? How can I make it
understand? (Note that vi understands just fine and will tab this file
easily.. but I think any editor that defaults to opening files read-only
is a viewer, not an editor. ;)
Further, is there some command like:
M-x when-i-say-tab-i-mean-tab-damn-it
that will make emacs ALWAYS add a tab when I hit the tab button, whether
it seems reasonable to emacs or not? I've also yet to be able to find an
easy way to set tab width without editing a configuration file..?
Any assistance would be greatly appreciated.
