Term::Report - Easy way to create dynamic 'reports' from within scripts.

SYNOPSIS ^

   use Term::Report;
   use Time::HiRes qw(usleep);

   my $items = 100;
   my $report = Term::Report->new(
            startRow => 4,
            numFormat => 1,
            statusBar => [
               label => 'Widget Analysis: ',
               subText => 'Locating widgets',
               subTextAlign => 'center',
               showTime=>1
            ],
   );

   my $status = $report->{statusBar};
   $status->setItems($items);
   $status->start;

   $report->savePoint('total', "Total widgets: ", 1);
   $report->savePoint('discarded', "\n  Widgets discarded: ", 1);

   for (1..$items){
      $report->finePrint('total', 0, $_);

      if (!($_%int((rand(10)+rand(10)+1)))){
         $report->finePrint('discarded', 0, ++$discard);
         $status->subText("Discarding bad widget");
      }
      else{
         $status->subText("Locating widgets");
      }

      usleep(75000);
      $status->update;
   }

   $status->reset({reverse=>1, subText=>'Processing widgets', setItems=>($items-$discard), start=>1});
   $report->savePoint('inventory', "\n\nInventorying widgets... ", 1);

   for (1..($items-$discard)){
      $report->finePrint('inventory', 0, $_);
      $status->update;
   }

   $report->printBarReport(
      "\n\n\n\n    Summary for widgets: \n\n",
      {
            "       Total:        " => $items,
            "       Good Widgets: " => $items-$discard,
            "       Bad Widgets:  " => $discard,
      }
   );

DESCRIPTION ^

Term::Report can be used to generate nicely formatted dynamic output. It can also use Term::StatusBar to show progress and Number::Format so numbers show up more readable. All output is sent to STDOUT by default.

The current release may not be compatible with previous code. Many changes were made with regards to how output could be formatted.

METHODS ^

new(parameters)

   cls       - This clears the screen. Default is 1.
   startRow  - This indicates which row to start at. Default is 1.
   startCol  - This indicates which column to start at. Default is 1.
   numFormat - This indicates if you want to use Number::Format. Default is undef.
   statusBar - This indicates if you want to use Term::StatusBar. Default is undef.
   fh        - User-defined file handle. This is passed on to Term::StatusBar. Default is STDOUT.

numFormat and statusBar can be passed in 2 different ways.

The first way is as a simple flag: numFormat => 1

Or as an array reference with parameters for a Number::Format object: numFormat => [-MON_DECIMAL_POINT => ',', -INT_CURR_SYMBOL => '']

statusBar behaves the same way except takes parameters appropriate for Term::StatusBar.

finePrint($row, $col, @text)

This gives more control over where to place text. With the introduction of 'save points', $row may be either a number, indicating a row, or a savepoint label, which may not be all numbers or it will be interpreted as a row.

printLine(@text)

This places text after the last known text has been placed. It tries very hard to "Do The Right Thing", but I am certain there are more 'bugs' in it.

lineLength('m')

Returns length($obj->{m}). This function shouldn't really be called as it has little purpose outside the module.

_adjustCurRow($text)

Internal function printLine() uses to try and place text properly.

printBarReport($header, $config)

Works in conjunction with Term::StatusBar to print a summary of data it processed.

savePoint($label, $text, $print)

Allows the referencing of a screen position with a text label. This calls printLine() and remembers the position it was placed in, along with the text it represents. $print is a flag indicating whether to immediately print the $text, or to delay it.

clear()

Clears the screen and resets currentRow to startRow. This is mostly for re-using the report object within the same script. The actual cursor is set to (0,0).

finished()

Accurately places the cursor at the last line of the 'report'.
