What I want to do is: What is supported in many programming languages but not in modern D programming language: String Interpolation I believe this will be done using the template.

I've just discovered[1] that I had a DConf 2020 presentation which is somewhat related to this thread. Initializing the D runtime appears at this point: https://youtu.be/FNL-CPX4EuM?t=2585 Ali [1] I am not kidding!

Are there any methods to get the screen resolution?
Call DisplayWidth/DisplayHeight on the X connection... my
simpledisplay.d provides bindings (though not a high level helper
function since both X and Windows calls are trivial)
On C/C++ from under X11, it is not possible to do this on the
command line via SSH, since the display is not defined.
Just defined the display, that's easy.
import std.process;
enviornment["DISPLAY"] = ":0";
that can work with any lib, then connect.
OR, with my lib, it is all included:
---
import arsd.simpledisplay;
XDisplayConnection.setDisplayName(":0"); // set the local name
regardless of what is set on ssh
auto connection = XDisplayConnection.get(); // connection
import std.stdio;
writeln(DisplayWidth(connection, 0), " x ",
DisplayHeight(connection, 0)); // the 0 is the screen number
---
Though note with a multiple monitor system, this will give the
*full* size of the virtual screen, not individual screens.
simpledisplay has methods for this. but I marked it `private`
and it only loads the data when a window is created... you COULD
hack past this anyway but prolly not worth the hassle. Maybe I
will make it public officially in the next release.
But if you are desperate for the info now, here's how you can
bypass private and get at it anyway:
---
// use reflection to bypass `private`
alias MonitorInfo = __traits(getMember,
arsd.simpledisplay.SimpleWindow, "MonitorInfo");
// make a temporary window just to get the info
auto window = new SimpleWindow(1, 1, null, OpenGlOptions.no,
Resizability.fixedSize, WindowTypes.eventOnly);
// this is the function that actually loads the monitor info
window.actualDpi();
// make sure none waiting in a buffer
flushGui();
// and now get the data out
foreach(monitor; MonitorInfo.info) {
writeln(monitor.position.size);
}
window.close();
---
But since you're bypassing private and poking internals, if/when
I do decide to make this public instead of private, I'll probably
break this approach (when it is public though you can just simply
loop over the info).

(https://docs.microsoft.com/en-us/windows/win32/api/winuser/nf-winuser-getsystemmetrics) Been a while since I've done any Win32 stuff directly. In this age of multiple monitors, it's probably better to use `EnumDisplaySettings' on Windows. https://docs.microsoft.com/en-us/windows/win32/api/winuser/nf-winuser-enumdisplaysettingsa But the best option is like I said above: see how other libraries do it.

And is it possible to do this somehow by means of D, pulling out the system resolution of the installed display? Like C++, the D standard library doesn't have anything for this. It's platform specific. There are several open source libraries out there that include that functionality, so you could just look at one of them (GLFW, SDL, SFML, etc.) and do what they do for the platforms you care about. They all have to go through the same system APIs. For example, on Windows you can use two calls to `GetSystemMetrics` (one for the width, one for the height).
