is there a simple way to get the unqualified name of a class
at runtime without having to pass it through std.format?
`typeid(class).name` always yields the full classname,
including its module information (i.e.,
"modulename.classname"), where I only want "classname" on its
own.
https://dlang.org/phobos/object.html#.TypeInfo_Class.name is
all you have there, and it's just a string, so the simple way
is to manipulate the string.
string unqualified(string name) {
import std.string : lastIndexOf;
import std.algorithm : min;
const i = name.lastIndexOf('.');
return i == -1 ? name : name[min(i+1, $) .. $];
Parsing was always an option, but anytime I come across a
solution where parsing/formatting seems to be the answer, it
always feels more hacky than a genuine solution. Hacks can be
fine, especially in low-frequency code like the stuff I'm
revisiting this month, but I always prefer direct library-based
or language-based solutions whenever humanly possible. Dlang's
reference docs unfortunately assume a level of expertise with the
language (especially, expertise with code generation and compiler
specs) that makes it much harder for me to "ask the right
questions" when I'm searching: I'm really not much of a
programmer. Heh.
