[D] http+json

[cyrusmsk]

Not sure if you are interested in PRs.
I was wondering how D will do http + json.

On my M1 machine LDC is the most popular option (DMD will require Rosetta, GDC probably possible to build, but there is no pre-generated packages).
LDC is LLVM based D backend. And it is providing more optimized code, but it takes more time for compilation, than reference compiler DMD.

So in D world popular flow is: using DMD in developing iteration, and LDC for preparing deployable to production binary.
So on x86 systems DMD should be even faster!

Using DUB for building I have (with /usr/bin/time):

initial build:
0.40 real 0.37 user 0.05 sys
Second build:
0.05 real 0.03 user 0.00 sys

With go build I have (actually the first build took 2s - probably because it was downloading packages):

Initial build:
0.30 real 0.37 user 0.21 sys
Second build:
0.09 real 0.11 user 0.20 sys

import std.stdio: writeln;
import std.json: parseJSON;
import std.net.curl: get;

void main()
{
    auto luke = get("https://swapi.dev/api/people/1").parseJSON();
    writeln(luke["name"].str, " has ", luke["eye_color"].str, " eyes");
}
