I want to define alphanumeric characters in an easy way.
Something like that:
char[] arr = ['a'..'z', 'A'..'Z', '0'..'9'];
Though above example doesn't work. Is there any easy way to do
this?
I am trying to do something like EBNF definitions. So, I do
not want to use loops, or define every single thing one by one
by hand.
There are convenient constants defined in std.ascii.
import std.ascii;
string arr = lowercase ~ uppercase ~ digits;
// also 'std.ascii.letters' gives ('A' .. 'Z' ~ 'a' .. 'z')
Well, that's just disguising what we can't do.
D has alot of compile time structures, even much complex than
what I asked. So, this type of thing should be doable for
immutable arrays.
