rgareusis there a LV2 host that supports the displayPriority port property?16:54
*** sigma6 has quit IRC16:56
*** yann-kaelig has quit IRC17:03
*** yann-kaelig has joined #lv217:04
falktxthere will be soon17:04
falktxwe're going to use it for mod17:04
falktxcarla should do that too, sometime soon before 2.0 is finalized17:05
falktxrgareus: if you add that property to your plugins, that will be a nice start17:05
rgareusfalktx: the setBfree leslie had it for years17:08
rgareusthe version in debian/stable already features it.17:08
rgareusoldstable, even :)17:08
rgareusthe issue I'm trying to address: I keep adding ports.  some of the newer/later ones however should be listed first17:39
falktxso you think hosts should be ignoring indexes?17:39
rgareuswhile most hosts only check for  lv2:symbol,   I currently also keep lv2:index,17:40
falktxseems doable to in carla17:40
falktxI don't keep the real lv2 index, I have an internal index in order to have audio / control buffers separate17:40
rgareusthe alternative would be to re-order port lv2:index .   I think displayPriority is really only intended for "window is too small"17:41
rgareusfalktx: makes sense. I think it was only nedko's old LV2 host that preferred displayPriority over lv2:symbol17:41
rgareusfalktx: makes sense. I think it was only nedko's old LV2 host that preferred lv2:index over lv2:symbol17:42
rgareusardour (and maybe also jalv?) tries to be smart and auto-groups  ports by lv:name (using some gtk similarity match)17:43
HarryHaarenaren't there port groups for that?17:44
HarryHaaren(assuming plugin devs actually group the ports)17:45

ssj71can anybody read this? https://mountainbikesandtrombones.blogspot.com/b/post-preview?token=Mx0o3E0BAAA.wPrFdI1jAqMxD07gcQjZ7A.RbskwmrdX4YCkWJf9iZcTw&postId=3809250968421114787&type=POST22:29
HarryHaarenssj71, its a "preview" but yes22:31
ssj71HarryHaaren: ok, I'd like someone to review it before it goes live22:32
ssj71Its a bit lengthy though22:32
* HarryHaaren notes links are broken in blogger.com previews, so i can't check them22:32
ssj71ah22:32
HarryHaarenno problem though - i'm reading the content now22:32
ssj71I guess I could post it and just repost if anything is found22:33
HarryHaarennah don worry, gimme a few mins to read22:33
HarryHaaren:)22:33
HarryHaarenssj71, "event port" is a double term.. because there is a port type called an "event" port22:35
HarryHaaren(before Atom came along, and saved the day, Event ports were used for MIDI messages22:35
HarryHaaren)22:35
HarryHaarenin the section "Now we need a port for this parameter", i suggest removing references to Event based port22:36
HarryHaarenand just jump to "we use an Atom port" or something to that effect?22:36
HarryHaarenso far so good though..22:36
ssj71IIUC the atom port is still an event port as atoms are event based opposed to a sampled signal22:37
HarryHaarenyes true22:37
ssj71its just not the same as the legacy event port22:37
HarryHaarenexactly.. which might lead to confusion?22:37
HarryHaarenideally run the article by drobilla.. he's the guy who really gets this, and knows whats planned too22:39
ssj71HarryHaaren: I've edited it, If you reload the page does it update or do you need a new URL?22:39
HarryHaareni think a new url, based on the big hash in the preview urls22:40
ssj71could be, when I reloaded it did update22:40
HarryHaarenoh ok, leme try22:40
ssj71https://mountainbikesandtrombones.blogspot.com/b/post-preview?token=1PAy3E0BAAA.wPrFdI1jAqMxD07gcQjZ7A.hOoDP2nntKgZLlAOG___ng&postId=3809250968421114787&type=POST22:40
ssj71just in case22:40
HarryHaarenyep updated on old url22:41
HarryHaarenreads better, good stuff22:41
ssj71sweet. Thanks for taking the time, let me know whatever thoughts you have22:42
ssj71HarryHaaren: has drobilla been around today?22:42
HarryHaarenhaven't seen him22:42
HarryHaarenoh wait, he timed out at like 15:00, so 8 hours ago22:43
HarryHaarenyes22:43
HarryHaarenin answer to your question :)22:43
HarryHaarenssj71, is there a way you can <code> tag the TTL and code? Would make it easier to read IMO22:44
HarryHaarenor <pre> boxes would be good?22:44
HarryHaarenexample <pre> boxes as on OpenAV site: http://openavproductions.com/real-time-latency-tuning/22:44
ssj71HarryHaaren: I am using <code>22:45
HarryHaarenoh ok, <pre> ?22:45
HarryHaarenthat makes the little copy-paste boxes IIRC, which can be nice for people looking to snippet your code and steal it ;)22:45
ssj71HarryHaaren: in addition to <code> or as substitute?22:45
HarryHaarenaddition i guess22:46
HarryHaaren<pre> <code> code here </code> </pre>22:46
HarryHaarensuggestion: "File IO is NEVER realtime safe" -> "File I/O is NOT realtime safe"22:46
HarryHaarenit *can* be RT safe, if the file is already in cache, and OS can read it directly from memory (aka, mmap() file access)22:47
HarryHaarenits a detail - for the sake of this guide I guess it don't matter22:47
HarryHaarenNEVER is stronger than NOT i guess.. but slightly misleading too22:48
HarryHaarenin a good way :D22:48
HarryHaarensuggestion: skip the Xrun explaination, just link RT-101 as you have. Mentioning threads here will probably scare people more than anything22:49
* HarryHaaren apologizes to ssj71, i seem to be quite a picky proof-reader22:51
ssj71HarryHaaren: unfortunately its somewhat germane to the topic of worker extension. let me look at it22:51
ssj71I'm still working on the <pre>s :)22:51
*** grejppi has quit IRC22:53
ssj71HarryHaaren: got the <pre> tags in but it didn't seem to make a difference. I think I need a different blogger template or whatever,22:54
ssj71I don22:54
ssj71t't really enjoy messing with css and that sort of stuff22:54
HarryHaarendon't stress the <pres>22:54
ssj71well its been a source of dissatisfaction for me with my blog for a while. But its also something I don't want to spend time on22:56
HarryHaarenfair enough i think22:57
HarryHaarendo you play trombone? Just reading the url now22:57
ssj71HarryHaaren: yep. Thats the only thing I gig on really22:58
HarryHaarenoh cool, must ask you for some (easy) fun funky tunes, i'm in the (slow) process of learning trumpet :)22:58
HarryHaarennice - down at the end now23:00
*** grejppi_ has joined #lv223:03
*** rncbc has quit IRC23:03
HarryHaarenhey grejppi_23:07
*** gianMOD_ has joined #lv223:08
*** gianMOD has quit IRC23:11
*** grejppi_ is now known as grejppi23:14
grejppiHarryHaaren: hey there23:15
HarryHaarenhey hey, how are you?23:15
grejppiHarryHaaren: I guess I'm fine, what's up?23:16
HarryHaarenjust chatting about all things LV2 here - ssj71 wrote a tutorial/article for Lv2 Atoms, was proof-reading that23:17
HarryHaarenwas reading that, done now.23:17
HarryHaarengrejppi, how are your projects coming along?23:17
grejppiHarryHaaren: sluggish23:18
grejppiwell, I had a huuge load of assignments to do by the end of last month so I'm taking a break first23:20
HarryHaarengood - that's part of it :)23:21
ssj71HarryHaaren: sorry I got pulled into a meeting there. I'll look at the thread discussion and see if I can make it more accessible23:24
HarryHaarenssj71, all good, sure.23:24
HarryHaarenbreak it "out" of the main article as much as you can i'd say - perhaps even a different post23:25
* HarryHaaren thinks its an interesting topic, might do an LV2 threading code tutorial23:25
*** ricardocrudo has quit IRC23:26
*** yann-kaelig has quit IRC23:29
ssj71HarryHaaren: I've tried to remove the discussion about thread. There are still a couple places I didn't see a good way around it, but I hopefully expained it well23:58
ssj71don't feel bad if you have additional criticism. Its all been constructive.23:59
HarryHaarenssj71, ill reload and re-read the threading bits23:59
ssj71thx23:59
