Re^6: [perldebugger] calling perldoc from within the debugger (REPL) (THX!)

[LanX]

Thanx, look really easy ... nice work pemungkah! 8)

I have to figure out a good automated context strategy...

... hmm ...I think it's appropriate to default to list evaluation like with the x-cmd since I can always use scalar to do otherwise.

But it's somehow useless to get just one line with index 0 for dumping a scalar

  DB<4> print "my father plays dominos\n"
my father plays dominos
0  1

Do you know a way to change this behavior automatically for a one element list like with p-cmd?

  DB<4> print "my father plays dominos\n"
1my father plays dominos

as far as I can understand from the docs of DB it's neccessary to manipulate dumpvar.pl to achieve this... right?

What you're seeing here is an 'x' of the print's return value, which is of course 1 since the print succeeded. We can expand the replacement eval with a crude check for the function being a print, in which case we leave $onetimeDump off.

sub smarter_eval {
  local $onetimeDump = 'dump'
    if $_[0] =~ /\Aprint\s*\(?/;
  old_eval(@_);
}
