I have the following list that is generated where the fist item it the child and the second item is the parent:
b:a
c:a
d:b
e:c
f:c
And it needs to look like this when I am done:
+-b--d
a -+
+ +-e
+-c-+
+-f
Any help with this would be appreciated.
I'd suggest something along these lines...
use Graph::Easy;
my $graph = Graph::Easy->new();
my @nodes=('b:a','c:a','d:b','e:c','f:c');
my ($child,$parent);
# build the graph
foreach my $node (@nodes) {
($child,$parent) = split(":",$node);
$graph->add_edge($parent,$child);
}
# print the graph
print $graph->as_asciii();
I have no idea how to store this either.
Is there any reason you don't want to do this?
# save the graph by saving the list of original nodes
open($filehandle,"<","nodes.dat") or die("Can't open file 'nodes.dat'
+for writing: $!\n");
print $filehandle join("\n",@nodes);

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).
