I wonder if there is a simple way to extract Authority from an URL string.
What is Authority of URL: https://en.wikipedia.org/wiki/URL#Syntax



https://dlang.org/phobos/std_path.html
I was able to gather the filename of URL via std.path package function: baseName.

import std.stdio, std.path;
void main()
{
string url = "https://github.com/BoQsc/notes/archive/master.zip";

// Output: url filename: master.zip
writeln("url filename: ", url.baseName);

// Output: url path: https://github.com/BoQsc/notes/archive
writeln("url path: ", url.dirName);


}



However it seems that std.path lacks ability to extract Authority part that URL contains.

https://dlang.org/phobos/std_path.html#rootName
I tried std.path.rootName, but it didn't return Authority part of URL.

import std.stdio, std.path;
void main()
{
string url = "https://github.com/BoQsc/notes/archive/master.zip";

// Output: url path:
writeln("url path: ", url.rootName);
}


I'm questioning, if D lang will ever include simple URL parsing into their std Phobos library?

Curl added an api to access the URL parser it itself uses. It would say, it is just an pull request away.

For the time being you can e.g. have a look at the package arsd. It contains an url parser and is very small without any further dependencies.

Kind regards

idk about phobos, but I have one of these in my web server library

http://dpldocs.info/experimental-docs/arsd.cgi.Uri.html

(also copy/pasted to the http client lib)
http://dpldocs.info/experimental-docs/arsd.http2.Uri.html

you can copy/paste it too if you like.

This package appears good to me too, with decent docs and sane looking tests, at least for data extraction (mine was written more for the relative link handling)
