cperl indentation question

cperl indentation question

[mgwmgw]

I have been using emacs since the 1980's,
and I am doing perl development using cperl mode.
The coding style rules where I work require that lines of source are less
than 80 characters wide.
Also, if I have a perl command like this
my $variable = "very long string"
.  " another very long string";
The continuation "." should line up under the double quote at the beginning
of the first line.
If I have a function/sub call
function("very long string"
            . " another very long string");
this lines up just fine,
but I have not figured out how to line this up without parens.
Any ideas?

I mean lining things up by hitting tab
and letting emacs work out the indentation,
in case I did not make that clear.

I'd venture an guess that there's no such option.

You can request it via `M-x report-emacs-bug'.

Hi Mary-Anne,

had a look into, as delt with indents in python-mode. However, seems a non-trivial task to tweak the mode itself.
May a command help you which call manually at this occasion? Something like:

If previous line is an assignement, indent to beginning of RHS. Otherwise indent to the beginning of previous line.
Interested?

Best,

Andreas

Does not sound simple to me and, as far as I know, should not even be
the right way of line up. However, it seems to me that a lot of other
IDEs do not follow your rule too.

This rules are not mine, but that request by OP, writing:
