Perl Indentation

Perl Indentation

[Aaron Lenfestey]

This bug report will be sent to the Free Software Foundation,
not to your local site managers!
Please write in English, because the Emacs maintainers do not have
translators to read other languages for them.

Your bug report will be posted to the bug-gnu-emacs@gnu.org mailing list,
and to the gnu.emacs.bug news group.

In GNU Emacs 21.3.2 (i386-pc-linux-gnu, X toolkit, Xaw3d scroll bars)
 of 2003-04-24 on raven, modified by Debian
configured using `configure  i386-linux --prefix=/usr --sharedstatedir=/var/lib --libexecdir=/usr/lib --localstatedir=/var/lib --infodir=/usr/share/info --mandir=/usr/share/man --with-pop=yes --with-x=yes --with-x-toolkit=athena --without-gif'

Please describe exactly what actions triggered the bug
and the precise symptoms of the bug:

Emacs is not correctly indenting my perl.  As in the example, it too much 
indents a line following a statement including '::'. 

{
    mylib::perlfunc();
      mylib::perlfunc();
}

A minor change causes correct behavior:

{
    mylibperlfunc();
    mylib::perlfunc();
}

Also, note that correct behavior is exhibited without the enclosing {}.

Thanks for the reply.
Its not indenting it. when I do M-x cperl-mode, there is no effect.

Thanks

Start Emacs without any init files:

emacs -q test.pl

Then do

M-x cperl-mode

Type in a short program, e.g.

#!/usr/bin/perl

if (scalar @ARGV)
{
 print "indentation test here\n";
}

Does line 5 not indent when you hit TAB?  It does for me.

It's not designed to automatically re-indent the current file.
Any new code you enter will be indented according to style, 
as well any line you press 'TAB' on. To set the particular
style, use cperl-set-style - my personal favourite is 'C++', 
even though it has problems with multi-line lists.

There's also 'perl-mode', which again will not automatically 
re-intent any of your buffer. It's a bit less colourful, but 
just as functional as 'cperl-mode'.

Yes. TAB Does the magic. But when you are writing tons of line, you
can not press tons of TABs.
So is there any block indentation technique? VIM has this feature.

For any region you can use C-M-\ (indent-region) or you can also use C-j
(newline-and-indent) instead of Enter (newline) when writing the code.

RE: perl indentation

[Bourgneuf Francois]

You may use perltidy.

I have inserted the following code in my .emacs, then C-c t will do the job on any marked region.
If you use activeperl, perltidy will be located in "Perl_Directory"/site/bin/perltidy

;; PerlTidy
(defmacro mark-active ()
    "Xemacs/emacs compatibility macro"
    (if (boundp 'mark-active)
        'mark-active
      '(mark)))
(defun perltidy ( )
  "Run perltidy on the current region or buffer."
  (interactive)
  (let ((orig-point (point)))
    (unless (mark-active) (mark-defun))
    (shell-command-on-region (point) (mark) "perltidy -q -ci=2 -bli -l=0 -lp -vt=1 -vtc=1 -nsfs -ndln" nil t)
    (goto-char orig-point)))
(global-set-key "\C-ct" 'perltidy)
