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

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

# Print translated code
print $p->debug;

DESCRIPTION

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::Lingua defines a simple language for users to create text flowcharts much easier.

This module provides two styles of interface for users to choose, as shown in SYNOPSIS.

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  => "BEGIN",
        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

NOTES

  • Variables does not come with the dollar sign ($).

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

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

  • Arguments are grouped by ':'

  • Every statement should be ended with a semicolon.
