bmc2ly: Braille music to LilyPond conversion

[Mario Lang]

Hi Lillies!

I am new here, so let me shortly introduce myself.  I am a a Linux and
Free Software user since 1997.  Computers and music have always been one
of my hobbies.  Since about 4 years now I am working on Open Source software
to process (first write, now read) braille music code.  Braille music is
a rather old standard, dating back to 1880.  It has been streamlined
since in various international meetings.  Basically, it is a way to
write a typical musical score in a tactile, linear manner.
In case you wonder, yes, I am blind myself.  That is why I spend my free
time playing with such obscure (almost cryptic!) things :-).

My current subproject in that area is parsing braille music code and
converting it to another (visual) representation.  While I have worked
lots with MusicXML in the past, it made more sense to start with
LilyPond when it comes to exporting my parse results.  This is what I
currently do, and what has resulted in a tool called bmc2ly.  It takes
Braille music code from stdin and converts it to a LilyPond score file.

As a small teaser, I include two examples in this mail directly.  First
is the braille music code, followed by the LilyPond source created from
bmc2ly.

If you have any interest in what I am doing, please make sure to drop me
a mail.  If you know of people that could benefit from this work, please
let them know.  If you are interested in this topic and you are looking
for a project to contribute to, please consider helping.  I am more or
less on my own currently, and while I have learnt a lot about visual
music notation, writing a translator between the tactile and the visual
world without being able to actually see the visual results is quite a
crazy job.  Its fun, but I could use a helping hand here and there.

BMC (the project of which bmc2ly is a part of) has not been publicly
released yet.  It lives on GitHub though, and can be built from there
directly.

So, without further delay, here are my teasers :-).  Thanks for your
kind attention.
