( [id://3333]=superdoc: print w/replies, xml ) Need Help??
It's hard to test without having code I can run, but I changed a couple lines (marked w/ comments in the code and described more completely below) to get the functionality I think you want. Does the following work how you want it to?
sub extractData { my @projects; push( @projects, [readOnly("$proj Data.txt"), "A"] ); unless( $pointerProj eq "NONE" ) { push( @projects, [readOnly("$pointerProj Data.txt"), "B"] ); } for( @projects ) { my @data = @{ $_->[0] }; # WAS: my @data = @{ $_[0] }; my $key = $_->[1]; # WAS: my $key = $_[1]; ... } } sub readOnly { my @contents; my $filePath; my $file; my $errMsg; $filePath = "$path\\" . $_[0]; $errMsg = "Unable to read $filePath: $!"; open $file, '<', $filePath or die $errMsg; @contents = <$file>; close $file; return \@contents; # WAS: return \@contents; }

I changed readOnly() to return an array reference. Each project is then an array reference with another array reference (the 'data') at index 0 and a text string (the 'key') at index 1. To get these two items, you need to dereference the outer array reference with $_->[X]. You used $_[X] which is how you get an item from an array, not an array reference.

Title:
Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post; it's "PerlMonks-approved HTML":



  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • 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).
  • Want more info? How to link or How to display code and escape characters are good places to start.
