We're still a few days away from release, but don't think anything else
is going to change. And I /really/ don't want to have to write this
changelog (and then merge into later versions) on the 25th.
Speakers can now play arbitrary PCM audio, sampled at 48kHz and with a
resolution of 8 bits. Programs can build up buffers of audio locally,
play it using `speaker.playAudio`, where it is encoded to DFPWM, sent
across the network, decoded, and played on the client.
`speaker.playAudio` may return false when a chunk of audio has been
submitted but not yet sent to the client. In this case, the program
should wait for a speaker_audio_empty event and try again, repeating
until it works.
While the API is a little odd, this gives us fantastic flexibility (we
can play arbitrary streams of audio) while still being resilient in the
presence of server lag (either TPS or on the computer thread).
Some other notes:
- There is a significant buffer on both the client and server, which
means that sound take several seconds to finish after playing has
started. One can force it to be stopped playing with the new
`speaker.stop` call.
- This also adds a `cc.audio.dfpwm` module, which allows encoding and
decoding DFPWM1a audio files.
- I spent so long writing the documentation for this. Who knows if it'll
be helpful!
Plan here is to release 1.98 for 1.16.x and 1.17.x and 1.97.1 for
1.15.x. However, will let this sit for a few days while I sort out 1.98
and the 1.17 port just in case any more bugs pop up.
- Allow help files to use the ".md" suffix, and move changelog/whatsnew
to use them.
- When files end with ".md", the "help" program attempts to highlight
them. This involves:
- Colour code blocks with a lightGrey background.
- Replace lists to use bullet points instead of "-"/"*".
- Colours headings yellow.
The implementation of this is a bit janky because a) I wrote this and
b) we need to run this step before text wrapping, but preserve
colours and section positions over wrapping (thanks to Jack for
getting this working).
- Add section navigation to the help viewer, with left/right to move to
the next/previous section.
Closes#569
