Quick and dirty song parser to play obligatory Super Mario Bros. theme song.

[lberezy]

This works on my MacBook Air (Mid 2013).

I wrote this small song parser very quickly to get the theme song to Super Mario Bros. playing.
The song does not repeat as the file pointer is not wound back to the start. Unexpected data in the file will most definitely break the parser.

[rocketinventor]

@lberezy It seems like it would be easy to add a quick and dirty if statement that checks for a token such as :end; or :repeat; and resets the file pointer. Do you think you could do that?

[fulldecent]

Is this a standard file format for the audio tune?

[lberezy]

@rocketinventor: almost certainly that is possible, but read on because...
@fulldecent: Nope, I don't think this is a standard file format, but it was one of the first results in Google for "super mario theme frequencies". I just threw this together a short while before bed last night so it's exceptionally dirty.
Perhaps it might be possible to add an MML parser or even a much more complex MIDI parser.

Take a look at the example from the tinyMML parser, looks straight forward to implement.

[rocketinventor]

@lberezy @fulldecent It seems excessive to add an MML parser or a MIDI player to the main program, at least at this point.
I like what @lberezy did because it has little overhead and makes it more modular so that it is possible to change the set of frequencies being transmitted easily without having to change or recompile the main program. Having a list of commands with a simple syntax is also great because the file could be systematically edited to transmit other types of data.
The only problem with the pull request in my opinion would be that it doesn't loop, so adding a loop statement would bring functional parity to it.

Having a separate program that parses MML or MIDI and spits out a list of frequencies in the format of the smb.song file might be a fun idea and could be implemented in any language without introducing bugs into the main program or making it bloated.

[lberezy]

I completely agree. The tinyMML parser is the smallest fully fledged song
solution I could find and I was already thinking it was far too big. Does
anyone know a more common and simple song description format?

And yes, I'll get around to adding in a loop.

It now repeats on the ":end" token in the song.

[rocketinventor]

Awesome! I hope it gets merged!

I kind of have a json descriptor idea here that I made for a game engine based on that old music tracker software that I can't recall the name right now. It's basically an array of channels, that are an array of beats each that's a array that includes first the note, than the instrument, and then the volume. I ditched effects and have a synthesizer one folder up. It's missing a bpm field right now.

@lberezy As you can probably see, I have ported your code, as well as the smb.song file over into the Vanilla JS version.
I'm looking for testers (It should work the same as #20 but just want to make sure).

[fulldecent]

Blocker #28

[rocketinventor]

@lberezy Thank you for your contributions! I'd love to see it added to the main branch but, that is currently not possible (because of the conflicts). Do you have any plans on updating the source for the new parser?

Here is conversion to .song format:

Sorry for the glacial pace here. And... it's merged! Thank you. Also updated to standardized tune format for #28.
