Does not render correctly on OS X

[eliheuer]

I just tested commit 9b1c006 on Arch with Nightly and it worked without issues.

However, on macOS 10.15 I get a series of errors. It would be nice if this worked well on macOS and I'm happy to be a macOS tester for this editor.

The first error I get reads:

error[E0599]: no function or associated item named `from_u32` found for type `char` in the current scope
   --> src/glifparser.rs:203:23
    |
203 |                 char::from_u32(u32::from_str_radix(unicodehex, 16).expect("<unicode> hex not int"))
    |                       ^^^^^^^^ function or associated item not found in `char`
    |
help: you are looking for the module in `std`, not the primitive type
    |
203 |                 std::char::from_u32(u32::from_str_radix(unicodehex, 16).expect("<unicode> hex not int"))
    |                 ^^^^^^^^^^^^^^^^^^^

I fixed this but got a few more errors and couldn't get it to build, I might try a PR to get it working, but thought I would post the issue first so you know I'm thinking about it.

Thanks!

I just forced pushed for the last time and promise to not do it anymore; can you try on the force pushed branch?

Nightly is required...I don't know why OS X isn't detecting that @eliheuer

[ctrlcctrlv]

Unless for some reason the OS X nightly rustc cannot do char::from_u32??

[eliheuer]

I just checked, I am and was using rustc 1.48.0-nightly on macOS.

[ctrlcctrlv]

🤔 Hmm...

Please let me know if you figure it out; that is very strange. Or, if you can find an alternative for the function that doesn't need Nightly.

I'm actively hacking on this right now to finally add the toolbox, as you saw on Twitter I converted all your icons into their own SVG.

So I hope I don't create a difficult merge conflict as I plan to refactor later probably

This is what I get at commit 6271987:

I kinda like the idea of this not working on mac now that I think about it.

[ctrlcctrlv]

I think that I'm requesting too high an OpenGL version for either Mac in general or your computer specifically.

[ctrlcctrlv]

The internet says that Apple hates OpenGL and that's why it's not working. 🙃

I would need your expertise to figure out how to lower our version. They deprecated it apparently. I'm not dropping it though, let's be clear. Nothing else works on Linux well, and that's the most important platform for this, even above Windows.

[ctrlcctrlv]

I think @kovidgoyal might know what I'm doing wrong also

[kovidgoyal]

Without looking at the code, make sure you are requesting an OpenGL version no higher than 3.3, that's the last that reliably works on macOS

I am:

Although I am using multiple contexts... Perhaps the other context is using a higher version. I'll need to investigate when I get on the computer, but the hard thing is I can't test on Mac. Does anyone know of a service that will allow me to rent and remote in to a Mac? Like via VNC? Of course having graphics is a must.

[ctrlcctrlv]

Update: It does build.

I posted on Twitter I was looking to rent a Mac and got a few nice offers. In the meantime, this is the trial version of Macincloud. So it does build.

I can't tell if this display problem is Macincloud's fault or not.

[ctrlcctrlv]

Update: It really is broken. A nice guy on Twitter gave me TeamViewer access to his Mac. Debugging...

[ctrlcctrlv]

More confirmation: it is not a problem with VNC. l33tguy on Twitter built it on real hardware and got this.

I wonder if rust-skia works at all on Mac.

Update: I've tracked the problem down. The problem is in Reclutch. All its examples are broken on OS X in some way. I've informed @jazzfool, hopefully they can help as they already have with #1.

Thanks everyone, @milezzz. #3 will close this. You're all welcome to try the branch early, but do note that you need to pull aclysma/skulpin to the parent directory as well if you do.
