Text::Flowchart::Script - A simple language for Text::Flowchart

  use Text::Flowchart::Script;
  my $p = Text::Flowchart::Script->new();

  # Parse the program
  $p->parse($program);

  # Draw the chart
  print $p->render;

  # Tokenize the source code
  print $p->tokenize;

  # Print translated code
  print $p->debug;

Text::Flowchart is a tool for generating flowcharts in ASCII style. However, users have to process some repeated things themselves, such as variable declaration, parentheses. As to this point, Text::Flowchart::Script defines a simple language for users to create text flowcharts much easier.

Now, let's get down to the language. See an example.

Initialize a flowchart.

        init : width => 50, directed => 0;

Let 'begin' be a box.

        begin = box :
                string  => "ALPHA",
                x_coord => 0,
                y_coord => 0,
                width   => 9,
                y_pad   => 0
        ;

Let 'end' be another box.

        end = box :
                string => "OMEGA",
                x_coord => 15,
                y_coord => 0
        ;

Draw a line from 'begin' to 'end'

        relate
              : begin bottom
              : end top
        ;

For details of the functions and parameters, see Text::Flowchart

* Variables do not come with the dollar sign ($).

* Users can treat an initialized variable as a function for modification of variable's attributes

* Users can insert comments quoted by /* and */

* Arguments are grouped by ':'

* Every statement should be ended with a semicolon.
