This module implements the Tcl Object Oriented Library framework, or TOOL. It is intended to be a general purpose framework that is useable in its own right, and easily extensible.

TOOL defines a metaclass with provides several additional keywords to the TclOO description langauge, default behaviors for its consituent objects, and top-down integration with the capabilities provided by the oo::meta package.

The TOOL metaclass was build with the oo::dialect package, and thus can be used as the basis for additional metaclasses. As a metaclass, TOOL has it's own "class" class, "object" class, and define namespace.

package require tool

# tool::class workds just like oo::class
tool::class create myclass {

# tool::define works just like oo::define
tool::define myclass method noop {} {}

# tool::define and tool::class understand additional keywords
tool::define myclass array_ensemble mysettings mysettings {}

# And tool interoperates with oo::define
oo::define myclass method do_something {} { return something }

# TOOL and TclOO objects are interchangeable
oo::class create myooclass {
  superclass myclass

Several manual pages go into more detail about specific keywords and methods.


TOOL adds new (or modifies) keywords used in the definitions of classes. However, the new keywords are only available via calls to tool::class create or tool::define

Public Object Methods

The TOOL object mother of all classes defines several methods to enforces consistent behavior throughout the framework.
