so I managed to draw a rectangle in pd gui with tk commands, but

• it is indeed going to be a lot of work to have a usable componant without using CICM
• pd code has absolutely no comments to rely on
• pucket code is plain horrible, even using GOTO... I mean wtf ?

I'll use it as is, and maybe later on if I got time, I'll try to implement something myself, but audio maths are always intimidating

anyway thanks everyone for the help

@phil123456: In a few days I should have an alpha release for the GUI port of Pd-l2ork. It adds substantially to data structure drawing instructions, so you can animate a rectangle like this:

[struct foo float x float y]

[20, 40 250( <-- animate the width
|
[line]
|
[width $1(
|
[draw rect 0 0 20 20]

[foo]

Actually, you can do that right now using the latest release of Pd-l2ork. (Though I've made a few API changes since then, this should still work the same way.)

@jancsika sorry I only work with free packages

@phil123456: Pd-l2ork is free of charge, and all the code uses free software licenses. The only exception I can think of is a single external library where the original author added a clause that it can't be used to oppress or kill people. (But if you were referring to that it's quit an obscure inside joke.)

@jancsika joke ?? I dotn follow you

I could have swore I saw pricing in the orange menus when I checked on the web site

but I use windows unfortunately

@phil123456: I checked here:

I don't see anything in the orange menus that would make someone think they have to pay to download a package.

@jancsika yes I know, but I am sure I saw something about pricing...no explanation here
