Morse code tools from read to write, analog to digital.
Targets Python3, tested against against CPython 3.3-3.6 and PyPy 3.
$ pip install sweetmorse
Use it from code:
>>> from sweetmorse.morse import Morse
>>> # Parse plain text, human readable, and binary Morse formats
>>> Morse.parse("SOS") == Morse.parse("... ___ ...") == Morse.parse("101010001110111011100010101")
True
>>> m = Morse.parse("SOS")
>>> m.human_readable
'... ___ ...'
>>> m.binary
'101010001110111011100010101'You get an executable that reads from standard in and performs conversions between sweetmorse's formats:
$ echo "Hello, Morse World!" | sweetmorse PLAIN HUMAN_READABLE > output.txt
$ cat output.txt
.... . ._.. ._.. ___ __..__ __ ___ ._. ... . .__ ___ ._. ._.. _.. _._.__
$ cat output.txt | sweetmorse HUMAN_READABLE BINARY
101010100010001011101010001011101010001110111011100011101110101011101110000000111011100011101110111000101110100010101000100000001011101110001110111011100010111010001011101010001110101
You can do the same with the main module, provided everything's in your PYTHONPATH:
$ echo "Hello, Morse World!" | python sweetmorse/main.py PLAIN HUMAN_READABLE
.... . ._.. ._.. ___ __..__ __ ___ ._. ... . .__ ___ ._. ._.. _.. _._.__
The BINARY format is perfect for sending and reading an analog Morse signal: step through the binary representation at a constant speed, sending a high signal for every 1 and a low signal for every 0.
See a proof of concept for interprocess communication with Morse code here (this just communicates between two GPIO pins on a Raspberry Pi in the same process, but use your imagination!).
