-- 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) });
...
}

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
