Charset::Baudot3pm

Usage

    use Charset::Baudot;

    my $a = baudot2ascii"(Baudot text)";

Overview

Charset::Baudot defines functions to convert between a subset of ASCII and a subset of nonstandard Baudot - the original Baudot allows only letters, numbers, and some punctuation. We assume that a "Shift to letters" code while already in letters mode means "Shift to lowercase" and "Shift to figures" while already in figures mode means "Shift to symbols". This allows to use up to 120 characters. However, for simplicity some characters are available in multiple sets, so the total is less than that.

By default, both functions baudot2ascii and ascii2baudot are imported in your namespace. If you don't want that, you know how to avoid it. They do the obvious thing to their first argument and return the transformed string.

There is another function, standardbaudot, not exported by default, which sets the module's behaviour to shandard Baudot.

Well, that's all.

Baudot character table

The following are the characters recognised. As described, the "shift" characters have nonstandard meaning.

Notes

This module reimplements some of the functionality of two other modules (see Exporter, Carp, Reinventing the Wheel). This is intentional, as it will leave larger scope for obfuscation in a future release.
