This package provides a class for the creation of simple dispatchers from character sequences to actions. Internally each dispatcher is in essence a deterministic finite automaton with tree structure.

Class API

The package exports a single command, the class command, enabling the creation of dispatcher instances. Its API is:

Object API

The objects created by the class command provide the methods listed below:


The simplicity of the DFA means that it is not possible to recognize a character sequence with has a another recognized character sequence as its prefix.

In other words, the set of recognized strings has to form a prefix code.

Bugs, Ideas, Feedback

This document, and the package it describes, will undoubtedly contain bugs and other problems. Please report such in the category term of the Tcllib Trackers. Please also report any ideas for enhancements you may have for either package and/or documentation.

When proposing code changes, please provide unified diffs, i.e the output of diff -u.

Note further that attachments are strongly preferred over inlined patches. Attachments can be made by going to the Edit form of the ticket immediately after its creation, and then using the left-most button in the secondary navigation bar.
