NAME

Math::SymbolicX::Calculator::Interface::Web - An AJAXy web interface to the calculator

SYNOPSIS

# simplest form of usage:
use Math::SymbolicX::Calculator::Interface::Web;
my $interface = Math::SymbolicX::Calculator::Interface::Web->new();
# But you probably want to use
# Math::SymbolicX::Calculator::Interface::Web::Server instead!

DESCRIPTION

This module implements an AJAX-enabled web interface to the Math::SymbolicX::Calculator.

This is alpha software!

You probably want to look at the symbolic_calculator_web_server script or the Math::SymbolicX::Calculator::Interface::Web::Server module which come with this distribution instead!

METHODS

new

Returns a new web interface object.

Optional parameters: (default in parenthesis)

calc => a Math::SymbolicX::Calculator object to use

execute_expression

Runs a single expression.

calc

Returns the Calculator object of this Web Interface.

exit_hook

Call this before stopping the web interface. It runs all cleanup actions such as those needed for a possible persistance.

This method doesn't actually kill your script, but returns after doing the cleanup.

error

Used to issue a warning to the user. First argument must be an error message to display. This is currently ignored for the web interface. Investigating methods to pass this to the client in a reliable fashion.

_parse_command

Parses generic commands such as exit and print.

This might change. (Name and implementation)

First argument: Expression to parse.

_generic_out

Generic output routine: Print Formulas and messages alike

Subject to change and refactoring.
