-- I'll leave the text here so that no else who reads this makes the same mistake. :-)
In your call to component_window(), you assign $pcrh and $pid a la
my ($prch,$pid) = @_;
now, I don't see a shift nor a pop nor any other @_ manipulations, which makes your call to tail_lines() incorrect:
sub component_window {
my ($prch,$pid) = @_;
...
my $tail = Tk::IO->new(
-linecommand => sub { tail_lines($prch, $_[0]) });
...
}
sub tail_lines {
my ($proc,$text) = @_;
...
}
because
$_[0] is the same as
$prch when you call
tail_lines($prch, $_[0]), and this seems to be not what you want.
You should be able to either pass the third element directly or get the third element in a var at the top of your sub (i.e.
sub component_window {
my ($prch,$pid,$text)=@_;
...
and pass that...
...
my $tail = Tk::IO->new(
-linecommand => sub { tail_lines($prch, $text) });
...
}
