Convert::Morse - Package to convert between ASCII text and MORSE alphabet. use Convert::Morse qw(as_ascii as_morse is_morsable); print as_ascii('.... . .-.. .-.. --- -- --- .-. ... .'),"\n"; # 'Helo Morse' print as_morse('Perl?'),"\n"; # '.--. . .-. .-.. ..--..' print "Yes!\n" if is_morsable('Helo Perl.'); # print "Yes!" perl5.6.0, Exporter Exports nothing on default, but can export "as_ascii()" and "as_morse()". This module lets you convert between normal ASCII text and international Morse code. You can redefine the token sets, if you like.

INPUT
ASCII text can have both lower and upper case, it will be converted to upper case prior to converting. Morse code input consists of dashes '-' and dots '.'. The elements MUST NOT to have spaces between, e.g. A is '.-' and not '. -'. Characters MUST have at least one space between. Additonal spaces are left over to indicate word boundaries. This means '.- -...' means 'AB' and and '.- -...' means 'A B'. The conversion routines are designed to be stable and ignore/skip unknown input, so that you can write: print as_ascii('Hello -- --- .-. ... . Perl!'); beware, though, a single '.' or '-' at the end will be interpreted as '. ' respective '- ' and thus become 'E' or 'T'. Use "Convert::Morse::error()" to check wether all went ok or not.

OUTPUT
The output will always consist of upper case letters or, in case of "as_morse()", of "[-. ]".

ERRORS
Unknown tokens in the input are ignored/skipped. In these cases you get the last error message with "Convert::Morse::error()".

as_ascii()
as_ascii(); Convert a Morse code text consisting of dashes and dots to ASCII.

as_morse()
as_morse(); Convert a ASCII text to Morse code text consisting of dashes, dots and spaces.

is_morse()
is_morse(); Return wether input is a true Morse code string or not.

is_morsable()
is_morseable(); Return wether input can be completely expressed as Morse code or not.

error()
error(); Returns the last error message or undef when no error occured. Can not yet do Japanese code nor German Umlaute. None known yet. Tels http://bloodgate.com in late 2000.
