Javier Salcedo#TIL that you can trigger frame captures on #metal 
programmatically, without needing to run your program through #Xcode
Here's a frame capture of my Metal-cpp #HelloTriangle, taken from within itself!
🤘🏻🔻
#Metal + #glfw with #cpp code only.
Had to avoid #objc because my custom build system can't deal with that yet (and I didn't feel like changing that).
What a pain to get it to compile.
BUT
It's using the exact same shader as my #Vulkan 
#HelloTriangle thanks to #Slang ❤️
AND
```
$ wc -l src/main.cpp src/shaders/hello_triangle.slang
134 src/main.cpp
40 src/shaders/hello_triangle.slang
164 total
```
Brian Swetland@avimanyuroy Okay, best response to this definitely goes to @tojiro who put together a nice, tidy, straightforward, and helpfully commented Hello Triangle demo:
