Clojurians Log v2

I'm trying the membrane examples. Button clicks responses are very slow. Is it intentional?

They should not be slow. What's the example you're trying?

plenty. Tried the counter and todo list. anything relating to clicks was very slow to respond. text input was snappy in file picker. In the REPL it does not happen

Is it on linux or mac?

linux

I haven't tested as much on linux. I'm wondering if it's not repainting on mouse input for some reason

What do you mean by "in the repl"?

I copied the example from the README and pasted it in the REPL

started with lein repl

and it's not slow when run from the repl?

correct

oh weird. One more thing to check, if you add a println in a mouse handler, is it slow to print?

let's see

That would indicate that the problem is that it's updating the state, but not repainting after mouse inputs for some reason.

Okay the behavior is even weirder

in the beginning it was slow to print and react

but if i click a button several times it reacts quickly and prints quickly

moving to another button is slow again

and speeds up after several clicks

hmmm, that is weird

yeah

another thing to check is try running the todo app with the swing backend lein run -m membrane.java2d

checking

Everything reacts immediately

ok, that means I'm probably doing something wrong when setting up GLFW that only manifests on linux

Thanks for helping me get more info here!

Gladly, if you need a test subject feel free to ping me

👍 , I already have a few ideas in mind.

Slightly easier reproducible builds would be nice, too, I would have wanted to build libmembraneskia.so myself and not have to download a release

although I see the steps now in the yml

It should be reproducible now. I use github to build it now.

yes, by bad, I didn't think to check the CI file

np, it's relatively recent.

Is it possible to build on linux without update-alternative?

I'm not sure. What's update-alternative?

update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-9 60 --slave /usr/bin/g++ g++ /usr/bin/g++-9

update-alternatives --config gcc 

With stuff like adding a ppa and globally modifying build settings, it might be better for linux users to build inside a docker image

Yea, that makes sense. I think it should compile with any c++ compiler

I think I just copied that from stack overflow as the "recommended" way to install gcc

I am not much of an expert on c++ build systems (as you may be able to tell)

I am not an expert on the subject, either 🙂

mostly fumbling my way through

ended up compiling GCC once in the hunt for missing libraries 🙃

Would you say membrane is mature enough to build an application with or should I use another framework in the meanwhile? I like the design philosophy but if I had to be practical, what would you recommend?

For desktop?

yes

With the intent of targeting all operating systems

Unless it's for personal or internal company projects, I think there's probably a few missing pieces right now 😕

😞

I'm working on getting it there, but there are still some rough edges

Since it's easy to embed, it might be possible to use membrane's cljfx or swing backends

so that you can use membrane for some things and fall back to cljfx or swing for other things

I'm not an expert with cljfx or swing, I should start with one thing

I would pick cljfx over swing, but all of my recent desktop projects for the last few years have been electron apps, which is the reason I've been working on membrane

What kind of app would it be?

An API app, which would traditionally be written in Electron

by the way, with targeting SKIA, do you have any plans for cooperation with Tonsky?

potentially. There's also a skija backend

I'm still not sure what his UI library will end up looking like, but hopefully there will be some ways to benefit from each others work.

We did a live chat on youtube about a week ago, https://www.youtube.com/watch?v=Nk6mcyv7Sz4

His chat two weeks ago with Raph Levien was really interesting, https://www.youtube.com/watch?v=PwuwG2-0n3I
