Although I am not sure but it may Range in D, has the same
concept that C++ has on iterator, like InputIterator or
OutputIterator, since I realized that the output of [ filter ]
does not have RandomAccessRange so I can not use input[ 0 ]. But
I can use input.front().
Also thank you @Stanislav Blinov, I am familiar with lambda but
have never seen a lambda in shape of string :)
---------------------------------------------------------
Solving the problem by using
split and empty in std.string
or splitter in std.algorithm or splitter in std.regex
plus
filter in std.algorithm,
and accessing the elements by:
input.front()
input.popFront()
---------------------------------------------------------
for input:
import std.stdio : print = writeln;
import std.algorithm: filter;
import std.string: split, empty;
void main() {
immutable (char)[] str = "one//two//three";
auto input = str.split( '/' ).filter!( element => !element.empty
)();
print( input.front );
input.popFront();
print( input.front );
input.popFront();
print( input.front );
}
the output is:
one
two
three
