Change line continuation behavior in cperl-mode

Change line continuation behavior in cperl-mode

[Steve]

Is there any way to change the indentation of continued lines (i.e.
lines ending in a ".") in cperl-mode? The current behavior is to add
an additional number of spaces to each continued line, so that, for
example, the second line is indented 2 characters, the next, 4, the
next, 6, etc, in an upside-down stair-step pattern. I'd like to have
all lines after the first indented the same (e.g. If the starting line
is at column 6, I'd like all the others to be at column 8). perl-mode
does this properly.

Thanks!

Steve

not sure, but have you tried customize-group with cperl?

in particular, there's a section on indentation with a lot variables
you can tweak.

in general, when behavior in some mode you don't like, first thing to
try is customize-group, followed by the mode name (may or may not end
in “-mode”). Not all major mode support this customize feature, but
most big ones or well written ones do.

Yes, that was the first thing I checked. There's nothing that
obviously applies to string continuation (not line continuation, which
works fine) on successive lines.

oh.

I looked into further your Q,... not sure what you mean though.

I tried this:


#perl
$some = "sme" .
    "what" .
    "that" .
    "and";
print $some;

but it seems to align? i'm not aware that perl line needs a dot to
signify continue? can you give a example?

I'm having the same problem as Steve mentioned and I also noticed that 
sometimes it seems to work. Most importantly, I get the staircase effect 
inside a sub, but not outside.
Example:

my $s = "this"
     . " string"
     . " is"
     . " long";

sub bus {
     my $s = "this"
         . " string"
             . " goes on"
                 . " and on";
}

I reproduced it. Don't know how to solve. Looks like its by design.
