Question: I see in your WDL repo 'from [short commit hash(?)]' in the commit msgs. What purpose serves this?

We pull changes from our private repository to the public WDL one, those commit hashes are for our reference. Comment...

I do sometimes and it has a nice feel and ritual but I don't think it's necessarily better. Just different. Comment...

Question: I think it is sensible to think that people learn things best when they "tinker with it". What sort of simple coding projects can be worked on, just for fun, that are enjoyable yet good for learning?

Question: Is there a design constraint that TypedBuf does not provide operator= and CopyFrom? In some cases I just use GetHeapBuf, etc, but I would love to hear the reasoning behind the decision. Excellent stuff, thanks!

It’s not terribly hard but the Culture series by Iain M Banks is a favorite. 4 Comments...

Question: I'm trying to resize dock depending on the theme and I thought it would be a simple matter of using SNM_GeSettIntConfigVar to change "docker2_right" but it doesn't get it. How come some variables from REAPER.ini are exposed to extensions and others are not? Is there some hack to get the rest?
Asked by John (93.138.8.x) on December 29 2018, 5:07pm
Reply on December 29 2018, 8:15pm:

Changing things isn't necessarily safe, because a lot of things are not re-read from the config etc. This sort of thing belongs in the dev section of the forum at any rate. Comment...

Question: Did you ever look into lua obfuscation. I see people recommend precompiling to achieve the same thing. Would that work with REAPER (I draw from previous experience where I couldn't make REAPER run pyc files). Oh, and merry Christmas to you, Cockos team and the rest of your gang!

Question: Do you have any source code available, maybe in a simple language like Python, that we can look at to learn from?

There are a lot of video processors and audio processors included with REAPER that are in a very simple language! I don't write much Python.

Question: What data structure and algorithms do you use to represent and maniputale midi in the piano roll? eg what happens when I cut and paste stuff around? I suppose it's not just a list of midi events?
Asked by diydaw (87.21.112.x) on December 21 2018, 12:59pm
Reply on December 22 2018, 2:38pm:

There are some separate lists, notes are combined into a structure that has the note on and note off events, CCs are separated out, etc. But they are flat lists... Comment...

Question: So searching the forums and can't really find the answer. Does REAPER use joint-stereo when rendering to MP3 with lame or not?
Asked by John (93.138.49.x) on December 17 2018, 4:14pm
Reply on December 17 2018, 4:41pm (edited at December 17 2018, 4:56pm):

Yes, it looks like it's always joint-stereo. We should probably let LAME decide, however it does appear LAME always chooses joint-stereo when it is not otherwise forced. 9 Comments...

Question: Which graphics APIs are used for each version or REAPER?
Asked by interestedInAPI (47.154.0.x) on December 16 2018, 10:19am
Reply on December 16 2018, 2:21pm:

Mostly just bitmap blitting via BitBlt() (windows), CoreGraphics (mac), or Cairo/gdk (linux). Except for video playback, which can use DirectShow (windows) or OpenGL (mac). Comment...
