Hi!

I searching trivial simple D/OpenGL working in 2021 year example.

It may be triangle.
It may be based on any library: SDL, GLFW, Derelict, etc.

Can you help me ?

https://github.com/drug007/gfm7/tree/master/examples/simpleshader

it's not trivial though but it works (tested in linux)
just `dub fetch gfm7` then go to `path\to\gfm7\examples\simpleshader` 
and run `dub`.

All kudos to Guillaume Piolat, original author of gfm library.

Thank, drug.
I think some like this:

   env DFLAGS=-wi dub run

or like this

   "buildRequirements": [ "allowWarnings" ]

without gfm/sdl2/timer.d editing.

Yes, you right. It can be removed. I will do it.

         try
         {
             SDL2Timer timer = cast(SDL2Timer)param;
             return timer.onTimer(interval);
         }
         catch (Throwable e)
         {
             // No Throwable is supposed to cross C callbacks 
boundaries
             // Crash immediately
             exit(-1);
             return 0; // <--HERE WARMING
         }

It is worked! Thank!

If like me you hate OpenGL :) you can can also get

Thank, Guillaume Piolat.

I using CPU Pentium B970 It is old CPU, but even it contains a 
graphics accelerator.
Mesa DRI Intel(R) HD Graphics 2000 (SNB GT1), has 4 conveers on 
GPU.
Smartphones also contains GPU.
Because OpenGL has high priority.

CPU render, may be later.

Thanks, I noticed turtle, dg2d. It has clipping, it usefull.
What about text rendering ?

 What about text rendering ?


Generally, text rendering on OpenGL is a huge pain to implement. This is
not specific to D, but to OpenGL in general, because OpenGL itself does
not have direct support for text rendering at all.  The usual route is
to use an existing text-rendering library like FreeType to rasterize
your text, then upload it as a texture to the GPU and render it as a
quad.

If you want to do a more modern approach, you could use signed distance
fields, but that requires some deep knowledge of how shaders work unless
you can find an off-the-shelf library that does it for you. You may
still end up needing FreeType or equivalent anyway, to get the SDFs in
the first place.

Here's something to start you off, if you don't already have an approach
in mind:

Dear Vitaly (Google translates it like that :)), I didn't touch 
that game for a while. I have just tried to compile and those are 
the steps to build and run it:

Using a Windows 10 x64. (Webassembly build needs crazy efforts, 
don't try it for now. If you are on a posix system please delete 
*.a folders from the root folder because they are for webassembly)

1) Open the dub.json or dub.selections.json, and change "bcaa": 
"~>0.0.5" to "bcaa": "0.0.5" (Recently a contributor and I have 
made some breaking changes in bcaa).

2) Have those lib and dll files in the root folder of the project:

chipmunk.lib // I manually compiled this one
libfreetype-6.dl
libjpeg-9.dll
libpng16-16.dll
libtiff-5.dll
libwebp-7.dll
SDL2_image.dll
SDL2_image.lib
SDL2_ttf.dll
SDL2_ttf.lib
SDL2.dll
SDL2.lib
zlib1.dll

basically, those are win 64-bit builds of SDL2, its friends, and 
their dependencies. If you provide an email, I can send them to 
you via wetransfer.

For posix builds, you will have to figure those out.

You may also need to use the exact version of "bettercmath": 
"0.3.1".

 Can you help me ?


OpenGL is being replaced by vulcan, just to plug my little

Pretty beafy, but well vulkan is a lot more verbose compared to

Just disable shader compilation using dub, the shader only needs 
to be compiled once. Since you're on linux it fails to execute 
glslc.exe (the windows executable). If you compiled them yourself 
you can remove it from dub prebuild commands

Thanks, Danny Arends!
I fixed the configuration in dub.json, and in the application.d I 
fixed VK_API_VERSION_1_0. It worked!
