|---|---|---|
| rgareus | falktx: did you succeed to embedd NSViews (LV2#CocoaUI)? or does this only work with dedicated windows/showUI? | 10:55 |
| falktx | rgareus: full cocoa UIs | 11:05 |
| falktx | both in dpf and juce | 11:06 |
| falktx | rgareus: does ardour do lv2 cocoa uis? | 11:06 |
| falktx | I always forget... | 11:06 |
| rgareus | falktx: no, ardour does delegates everything to libsuil | 11:07 |
| rgareus | I suppose someone should implement suil cocoa_in_gtk2. | 11:08 |
| falktx | then cocoa_in_gtk3, qt4 and qt5 | 11:10 |
| falktx | still missing win32_on_gtk3, qt4, and qt5 as well | 11:11 |
| rgareus | falktx: I had a quick look at pugl_osx.m and that creates a window by itself. (testing with your carla-bridge-lv2-cocoa)... | 11:11 |
| rgareus | falktx: .. and wondered how that can be embedded. | 11:11 |
| rgareus | falktx: when running it with setBfree.lv2/upstream pugl I always get the dedicated window (not the NSView that is returned as widget) | 11:12 |
| falktx | it steals the window view I think | 11:14 |
| rgareus | falktx: pugl creates a window, and that's the one that will be used. the original (host created one) is hidden. | 11:17 |
| rgareus | falktx: I think pugl needs to be changed for a *true* embeddable NSView solution | 11:18 |
| falktx | my pugl already is true embed | 11:18 |
| falktx | when there's a parent view my pugl does not create the window | 11:18 |
| rgareus | falktx: I see. that makes sense | 11:21 |
| rgareus | falktx: does addSubview evantually call initWithFrame and provide colorBits and depthBits? | 11:21 |
| rgareus | falktx: or does your host do that? | 11:22 |
| falktx | hosts are supposed to init the view afaik | 11:22 |
| falktx | or it gets done automatically when the view is added to a window | 11:23 |
| rgareus | falktx: I just did a quick check and OSX only calls initWithFrame:(NSRect)frame | 11:23 |
| rgareus | falktx: the PuglOpenGLView's constructor is never called because the args are missing but the parent NSView is created | 11:23 |
| falktx | are you sure? wouldn't that make the view invalid? | 11:24 |
| rgareus | falktx: yeah it segfaults | 11:24 |
| falktx | I got mine to work here | 11:28 |
| falktx | zamaudio stuff too | 11:29 |
| falktx | rgareus: so you think PuglOpenGLView needs an extra constructor? | 11:29 |
| rgareus | falktx: I don't know yet | 11:33 |
| rgareus | falktx: can you gdb break in @implementation PuglOpenGLView | 11:36 |
| rgareus | initWithFrame() | 11:36 |
| *** rncbc has joined #lv2 | 11:36 | |
| rgareus | and get a backtrace? who calls that function? | 11:36 |
| falktx | sure, let me have launch first | 11:37 |
| rgareus | falktx: NSOpenGLView itsels only has a initWithFrame:pixelFormat constructor. | 11:37 |
| falktx | bbl | 11:37 |
| rgareus | so I wonder how apple knows to provide the extra args | 11:37 |
| *** bgribble has joined #lv2 | 11:41 | |
| wrl | you should have initialized your view before you addSubview | 11:56 |
| wrl | addSubview will result in a few other calls made to your view, in particular viewWillMoveToSuperview/viewDidMoveToSuperview | 11:57 |

| Joeboy | Would I be correct in thinking there's currently no way to write an LV2 plugin in python? | 16:31 |
| falktx | plugin? tricky | 16:32 |
| falktx | ui? can be done | 16:32 |
| falktx | lv2 expects a binary | 16:32 |
| Joeboy | The plugin bit is the bit I'm interested in right now. I guess you'd need some kind of bridge. | 16:33 |
| falktx | you can call some python stuff from C | 16:33 |
| Joeboy | I guess you could have a C plugin that took the path to a python file as a parameter | 16:34 |
| Joeboy | Anyway, unless it exists already I'm probably not that interested. | 16:35 |
| Anchakor | it's very impractical, C is really the best language for DSP | 16:35 |
| Joeboy | I was thinking about it for the DSP course I'm doing | 16:36 |
| Joeboy | Not for something to be used onstage etc | 16:36 |
| Joeboy | Just that it would be nice to be able to call a python script from audacity | 16:36 |
| Anchakor | if you want a nicer language to write DSP in, use faust | 16:36 |

| rgareus | Joeboy: there are less than a handful of scripting languages that are realtime-safe and python is not one of them | 17:41 |
| * rgareus knows only two RT-safe ones: lua and supernova (supercollider's scripting lang). | 17:42 | |
| Joeboy | rgareus: But, there are reasons you might want to process audio outside of realtime. | 17:42 |
| rgareus | Joeboy: sure. python is just fine and easy. | 17:42 |
| rgareus | but realtime is a different story. | 17:43 |
| Joeboy | Well, audacity allows you to run plugins on your audio, and realtime is obviously not relevant there. | 17:44 |
| rgareus | lv2file is the same (or jackd in freewheeling mode) | 17:45 |
