Clojurians Log v2

I'm trying to follow the tutorial in Ubuntu 20.04 with Java 11 and (skia/run #(ui/label "Hello world!")) exits immediately without popping up anything or throwing/displaying any error. the call evaluates to #object[clojure.core.async.impl.channels.ManyToManyChannel 0x2c203f38 "clojure.core.async.impl.channels.ManyToManyChannel@2c203f38"]

I tried to clojure.core.async/take! from that channel and my callback never gets called

hmmm, it seems like it should display an error if nothing happens

can you try using run-sync instead of run? (skia/run-sync #(ui/label "Hello world!"))

just to double check, which version of membrane are you using?

the channel should close when the all the windows are closed

run-sync gives me an error trying to load a font:

I'm using the version indicated in the tutorial: com.phronemophobic/membrane {:mvn/version "0.9.14-beta"}

ah ok. I'm seeing the same error. I think the issue is that I just forgot to update the linux build for this version. i'm rebuilding right now!

thank you! I'll give it a try as soon as it's rebuilt

ok, just uploaded [com.phronemophobic/membrane "0.9.15-beta"]

which doesn't appear to throw the same error on my ubuntu vm. (it's using a different version, but it's hopefully close enough 🤞)

it works now, thanks! for some reason I can't run this with cider-jack-in, but if it works when launching from a terminal I guess I can cider-connect

does it just hang when you use cider jack in? or is there an error?

run-sync hangs

it should hang until the window is closed

run returns the channel and nothing else happens

no window opens in either case

but if I run it from the terminal I do get a window

well, that's with run-sync. if I call run from the terminal I get no window (or maybe it gets created but the program exits before it gets a chance to show up)

ok. that's a bummer. I'll write up an issue so I can make sure to look into it

now, if I wait on a promise that gets delivered when the channel that run return closes, I do get a window

I've filed the issue at https://github.com/phronmophobic/membrane/issues/6 if you find any other info.

it's getting pretty late here, but if you run into any issues or goofiness, I'm absolutely looking for feedback. I'll try to look into the cider-jack-in issue tomorrow.
