Hello!
I'm quite new using PD. A couple of years ago my friend helped me create capacitive sensors using both PD and Arduino. However, since my old computer got stolen, I'm having a hard time knowing what libraries and setups I need on PD. This is a list of all the errors I get. Please.. help 😅

@me-andmymonkey Yes, for lists check out the list-abs library, all vanilla abstractions. Other things can be build using list-drip: https://forum.pdpatchrepo.info/topic/11122/faster-list-drip-with-list-store-pd-0-48.

With [text] you can sometimes do more because you can directly access lines. So a list would have to be organized vertically in lines. You can also drip a list into a [text], modify the contents and [text sequence] the contents into a [list-store] to have a list again. These are most of the time some effort to build, but all is doable.

I wanted to build PD on Windows 10 to get ASIO support. I failed when I used the "Source" files from the PD website. I succeeded when I used source that I cloned from Github. I followed the same instructions from the wiki both when I failed and when I succeeded. (They are the same as in the manual, just a little more concise.)

I am sharing below my terminal output from the failed build attempts from the downloaded source code (the tar.gz file). Some of these messages suggest that there might be errors in the makefiles. I don't know anything about makefiles, so I can't really interpret the errors. But I did want to pass them along, in case a developer might find them useful. Here you go:

Hello there, this seemed an interesting patch, so i unzipped it on a folder and tried to open it but got an unusable display and a string of errors on console, something like this (its not all of it);

@ingox Ha, I guess this highlights the number 0 paradigm for Pd-- always measure first!

It looks to me like message-passing overhead dwarfs the time it takes to copy a list once into [list store]. That single full list-copy operation (a for loop if you look in the source) is still significant-- about 10% of total computation time when testing with a list of 100,000 elements.

However, if you remove all message-passing overhead and just code up [list drip] as a core class, you consistently get an order of magnitude better performance.

So we have:

1. original list-drip: slow, but I can't find the code for it. But I hope it was just copying a list once before iteration, and not on every pass.
2. matju's insane recursive non-copy list-drip: faster than the original implementation
3. list store] implementation of [list-drip]: looks to be consistently 3 times faster than number 2 above, lending credence to the theory that message-passing overhead is the significant factor in performance. (Well, as long as you aren't copying the entire list on every pass...)
4. Add core class [list drip] to x_list.c and use a for loop to output each element from the incoming vector of atoms without copying anything. I quickly coded this up and saw a consistent order of magnitude performance improvement over the [list store] implementation. (Didn't test with gpointers, which will probably slow down every single implementation listed here.)

I think Matt Barber even had a case where removing a [trigger] object and replacing it with bare wires (and just depending on creation order) generated enough of a performance difference in a complex patch to warrant doing it. (Edit: this may have been in an abstraction, in which case the speedup would be multiplied by the total number of abstractions used...)

It's too bad that message-passing overhead makes that much of a difference. And while I can think of a potential speedup for the case of [trigger], I'm not sure there's a simple way to boost message passing performance across the board.

I thought [list store] and a "get" message avoided the need to split the list.

Why do you desire to avoid splitting a list? The cost is a) the pointer math necessary to index into an array in c, and subtracting the new index from the length of the list..

If the list you want to split somehow already exists inside your [list store] object, then both methods of "dripping" will/should be roughly comparable in speed.

On the other hand, if you are receiving a list from an upstream object chain (e.g., you're inside an abstraction purpose-written to split lists) and want to "drip" it, [list store] requires copying the entire list inside the object before splitting it. For very large lists that operation is not negligible. The [list split] object doesn't require any copies and is why it's used in that insane-looking recursive implementation of [list-drip]

This is why I rhink the [list-drip] implementation is instructive-- it shows clearly the problems that come trying to do recursion in Pd, and it shows clearly how writing performant abstractions often requires drilling down past the language's class boundary and directly reading the implementation. (Or the user has to pentest relentlessly to guess-and-check at the class boundary. Either way, it is unfortunate.)

Edit: clarification

Hey!

I have a list of let's say 8 number:
42 31 96 29 53 32 39 16

Then I sort them from low>high using list-sort abs from list-abs:
16 29 31 32 39 42 53 96

This works fine, but the next step I am not even sure where to begin with.

The next step I would like to do is to get the order of the reordered list, which in this case would be:
7 3 1 5 6 0 4 2

The 7th element of the original list is now first, the 3rd element of the first list is now second and so on.

How would I go about getting the order of the reordered list?

I would like to apply that same order from that list to some other lists.

I checked list-sort abs and printet some of the data from the different processes, but I didn't find the actual order. I am really not familiar with data structures.

Any suggestions?

(the length of is just an example, the lists are going to be longer, sometimes 16 elements, sometimes 64 elements.....=

Thanks!

Here is a starting point:
list-sort-help-com.pd

@ddw_music From what I understand, every time you send to the hot inlet of the standard list objects it iterates through the full list. In your list iterate example the [list] and [list split 1] each iterate through the full list, making two iterations. Your second does not, I did not look close enough on my first glance, but it does iterate through the list once more than [list store] would (assuming [list store] does iterate), 5 times for [list prepend] and once for [list]. For short lists this would notf matter, but could make a big difference on large lists, and a huge difference if [list store] prepends/appends without iteration, we will have to wait for someone more knowledgeable to answer that or just accept that it is faster and be happy at that.

I've modified some abstractions created by @60hz for prototyping fast with ofelia (BTW, thanks a million for your abstractions they're great! And of course a million thanks to @cuinjune for creating Ofelia!). Things seem to work OK, but there's this happening. I have the following patch (I've changed the names from [gl.draw] to [ofelia.draw] for this and other abstractions)

[ofelia.draw]
|
[ofelia.cube]

and I see a white cube in the Ofelia window. Then I make the following connections:

[ofelia.draw]
|
[ofelia.movie]
|
[ofelia.cube]

and I get a video playing in the same cube. Till now everything is fine. But if I go back to the first patch, I don't get a white cube anymore but a still from the video file from [ofelia.movie]. Here are the scripts of the abstractions (almost identical to @60hz abstractions):
[ofelia.draw] (I'm returning ofColor because I want to have all abstractions output pointers and not bangs, maybe there's a better solution for this):

ofelia d draw$0;
local c = ofCanvas(this);
local args = c:getArgs();
local depth = true;
local screenwidth;
local screenheigh;
local widthHeigh;
;
function M.new();
  if args[2] == nil then depth = true;
  else;
  M.depth(args[2]);
  end;
  if ofWindow.exists then;
  screenwidth = ofGetWidth();
  screenheight = ofGetHeight();
  end;
end;
;
function M.screensize(list);
  screenwidth, screenheight = list[1], list[2];
end;
;
function M.depth(string);
  if string == "3d" then;
  depth = true;
  else;
  depth = false;
  end;
end;
function M.bang();
  ofSetDepthTest(depth);
  ofTranslate(screenwidth*0.5, screenheight*0.5);
  return ofColor(255, 255, 255);
end;

[ofelia.movie]:

ofelia d -c17 videoplayer-$0;
local canvas = ofCanvas(this);
local args = canvas:getArgs();
local videoplayer = ofVideoPlayer();
local filename, start, loop = args[1], args[2], args[3];
local loaded = 0;
;
function M.new();
  ofWindow.addListener("setup", this);
  if args[1] == nil then print("No file found");
  else M.open(filename);
  end;
  if args[2] == 1 then M.play();
  end;
  if args[3] == nil then loop = 0;
  end;
end;
;
function M.free();
  ofWindow.removeListener("setup", this);
end;
;
function M.setup();
  M.open(filename);
end;
;
function M.open(string);
  if ofWindow.exists then;
    videoplayer:close();
    videoplayer:load(string);
    if (videoplayer:isLoaded()) then;
    print("loaded " .. string);
    videoplayer:update();
    end;
  end;
end;
function M.url(string);
  if ofWindow.exists then;
    videoplayer:close();
    videoplayer:load(string);

function M.volume(float) videoplayer:setVolume(float) end;
function M.loop(float);
  if float == 0 then videoplayer:setLoopState(OF_LOOP_NONE);
  elseif float == 1 then videoplayer:setLoopState(OF_LOOP_NORMAL);
  elseif float == 2 then videoplayer:setLoopState(OF_LOOP_PALINDROME);
  end;
end;
function M.get()
  return ofTable (videoplayer, videoplayer:isLoaded(), videoplayer:isPlaying(), videoplayer:getCurrentFrame(), videoplayer:getTotalNumFrames(), videoplayer:getWidth(), videoplayer:getHeight());
end;
;
function M.pointer(p);
  videoplayer:update();
  videoplayer:bind();
  return videoplayer;
end;
function M.bang();
  videoplayer:update();
  videoplayer:bind();
  return videoplayer;
end;

Inside [ofelia.movie] there's this patch:

[ofelia d movie_script] <- this is the ofelia object that loads the script above
|
[t a a]
|    |
|    [outlet]
|
[ofelia d videoplayer_unbind;] <- this is one object
[function M.pointer(p);      ]
[p:unbind;                   ]
[end;                        ]

and this is [ofelia.cube]:

ofelia d $0-box;
local c = ofCanvas(this);
local args = c:getArgs();
local width, height, depth, resw, resh, resd, drawmode, strokeweight = args[1], args[2], args[3], args[4], args[5], args[6], args[7], args[8];
local position, orientation, scale = ofVec3f(0, 0, 0), ofVec3f(0, 0, 0), ofVec3f(1, 1, 1);
;
function M.new();
  ofWindow.addListener("setup", this);
  if args[1] == nil then width = 100 end;

  if args[6] == nil then resd = 5 end;
  if args[7] == nil then drawmode = "fill" end;
  if args[8] == nil then strokeweight = 1 end;

end;

end;

  if drawmode == "point" then box$0:drawVertices() end;
  if drawmode == "line" then box$0:drawWireframe() end;
  return anything;
end;

This is a bit too much information but I think it's necessary if anyone can help. There's probably stuff I'm ignorant of. @cuinjune any hints?
