Failed to get a graphics device

[kristijanhusak]

Hi,

I wanted to give this a try, but I wasn't able to start it. I tried both release and cargo package.
This is what I get when I try to start it (full backtrace):

╰─ RUST_BACKTRACE=full neophyte                                                                                                                                                                                                              ─╯

Thank you for the report! It looks like I forgot to remove several GPU feature requirements that are not longer being used. Could you try with the latest changes on main?

I gave it a try, but now I'm getting a different error: Unsupported uniform datatype! 0x8DC6. Here's full backtrace:

[tim-harding]

Seems like GLES does not like vec2<u32> push constants. I've changed them all to vec2<i32>. See if that helps. Thank you for the reports, by the way. This is the kind of thing that's difficult to anticipate.

[kristijanhusak]

There's a progress :)

I gave it a try, and now I'm getting some error around fonts:

I tried using custom font with this in my init.lua, but it didn't help:

{
    'tim-harding/neophyte',
    opts = {
      fonts = {
        'JetBrains Mono',
      },
    },
  }

[tim-harding]

Seems like there aren't any fonts loaded. I should fix it so that it defaults to Roboto Mono instead of crashing due to an empty font list (edit: this is done in the latest commits). I tested with JetBrains Mono and it works alright for me, so either it's called something different on your system or font-loader has troubles with your platform. What system are you running on? And to clarify, though, does it still crash if you set opts = {}?

[kristijanhusak]

What system are you running on?

I'm running Arch Linux

And to clarify, though, does it still crash if you set opts = {}

Yes, I tried various things.

I don't know Rust, but I tried debugging the issue.

When I set a custom list of fonts, I checked if it propagates that to Rust.
It doesn't even come to the set_fonts here:

neophyte/src/text/fonts.rs

Line 69 in b215f06

pub fn set_fonts(&mut self, fonts: Vec<FontSetting>, size: FontSize) {

It panics while setting up an Event handler here:

neophyte/src/event_handler/mod.rs

Line 50 in b215f06

let fonts = Fonts::new();

It seems that this returns None

neophyte/src/text/font.rs

Line 56 in b215f06

let font = FontRef::from_index(data.as_ref(), index)?;

Then later metrics is not set, and it panics from there.

data is property set, it returns array of ints.

[tim-harding]

That is very surprising. The binary data for Roboto is included directly in the binary, so it doesn't make sense to me that it would be failing to load the default fonts. Swash doesn't depend on the environment from what I'm aware of either, and in any case I'm on Arch too. Here's my hunch. I added the fonts with Git LFS, and it seems that there might be a footgun where Git creates files with the same names but without actually downloading the data, which would mean we're including files that don't contain valid font data. Could you try running git lfs install and pulling again?

[kristijanhusak]

Tried git lfs install, same thing.
Do you have an idea how can I debug it?

[tim-harding]

Perhaps git lfs fetch? If that doesn't seem to fix it, maybe just verify that the fonts in src/text/fonts/ open correctly. Edit: Apparently git lfs pull is the right thing now.

[kristijanhusak]

Ok, after git lfs pull error changed again:

Alright, I figured out how to set the GLES backend for local testing and fixed this particular crash. As a consequence, however, I discovered that OpenGL in general does not support push constants, which I use across all the shaders in Neophyte. To support OpenGL, I will need to replace my use of push constants with uniform buffers, which will take a bit of time. In the meantime, I recommend installing Vulkan drivers if you wish to keep experimenting. Otherwise, I will let you know when OpenGL is supported. Notes on driver and Git cloning issues are also in the readme now.
