Creating new Alphabets for MorseTrainer


If you want to create a new alphabet for MorseTrainer you must use ResEdit, a program usually used by developers only. An alphabet definition is contained in a "CWAD"-resource. The name of the resource is also the name of the alphabet. The ID of the resource should be 1000+country number (7 for Sweden) if the alphabet is localized for a specific country. MorseTrainer uses the alphabet corresponding to the system used. That is if a Swedish system is used the CWAD resource with ID=1007 will be used as default (if nothing else has been selected). If no localized alphabet can be found the international CWAD will be used having ID=999. If you create an alphabet which is not intended for any special country give the resource an ID above 2000. The CWAD resource consists of plain text where each line describes a Morse character.

Example:

A •-
B -•••

The first character is the ASCII character and the sequence of "-" (DAH) and "•" (DIT) describes the corresponding Morse code. Two more fields can be used if needed:

A •- "This is A" "A"
B -••• "This is B" "B"

When a third string exists (within " ") the fourth must also exist even if it is empty. The third string explains the meaning of the character and the fourth string explains the keys to press (Ex: option-cmd-Q).

It's OK to write:

A •-
A •- "" ""
A •- "" "A"
A •- "This is A" ""
A •- "This is A" "A"

It's NOT OK to write:

A •- "This is A"
A •- ""

Before you start to experiment with the CWAD resource take a look at the existing alphabets!
