To build this, a zig compiler (tested: 0.14.1) is needed, run zig build --release=fast.

It will download https://github.com/chmod222/zuxn when building.

Hello!

You can configure associations to run .rom files in this config:
https://git.kolibrios.org/KolibriOS/kolibrios/src/branch/main/data/common/settings/assoc.ini

Also, you probably would like to configure icons for .rom files and additional associations (for some file managers), using config files in this folder:
https://git.kolibrios.org/KolibriOS/kolibrios/src/branch/main/data/common/File%20Managers

All available icons and numbers can be found in /sys/@reshare app, ICONS16/W section.

Add association and icon for .rom files, thanks.

Also implement the file device (without stat op), and remove the MPL-2.0 license file (which I think should be in the root folder so that each program don't need to store its own).

Hi!

Wanted to test it and realized that emulator itself isn't included in image auto-build yet.
To include it, you need to use KolibriOS TUP build system:

  • Add proper Tupfile.lua to emulator source code folder.
  • Add reference entry to general data/Tupfile.lua file.

You can get an example in this commit and adapt it to your Zig building pipeline:

Hi, it seems tup doesn't want to work with zig build, which will download 3rd deps and manage some cache itself.

May I commit the built binary into the repo?

Yep, if tup can't work with Zig - binary is okay.

Your project can be in a separate repo with autobuild. While building the OS, main workflow can just download an artifact from your CI

@iyzsong hi, and sorry for late response!

I finally tested your emulator, and have some feedback.
Overall, it works pretty fine, but there are some small problems:

  1. I can't open window in full screen, there is some weird top padding.
  2. There are some overdraws of window borders and shifted lines (highlighted in red). Take in account that each window in KolibriOS have a 5 pixel borders, as well as varying header height (depend on current skin).

Is it possible to fix them?

When creating a window, you can set a flag to start drawing coords from window client area (don't overlap borders), and call a separate function to get header height of current skin, and adapt your rendering accordingly.

No problem.

Yes, full screen is not supported, it only render at 1x/2x/3x. The weird you see is due to screen is too small for the left editor, run it at 1080p will show the correct border.

  1. There are some overdraws of window borders and shifted lines (highlighted in red). Take in account that each window in KolibriOS have a 5 pixel borders, as well as varying header height (depend on current skin).

I think that's skin drawing, I created the window with skinned, no fill and and relative coordinates. change to another skin show this, which i think is correct:

Oh, got it!
I tried to run KOS with bigger screen resolution, and now this problem is also gone.

Thus, I suppose, all is okay with this PR.
Thank you for your response!
