Re: about std.string.representation

[bioinfornatics]

I try this




import std.traits       : isSomeChar;
import std.typetuple    : TypeTuple;
import std.stdio;

template CharEncodingType(Char)
{
    // Get representation type
    alias TypeTuple!(ubyte, ushort, uint) U;

    // const and immutable storage classes
    static if (is(Char == immutable)) alias immutable(U) T;
    else static if (is(Char == const)) alias const(U) T;
    else alias U T;

    // shared storage class (because shared(const(T)) is possible)
    static if (is(Char == shared)) alias shared(T)  
CharEncodingType;
    else alias T CharEncodingType;
}

void main()
{
    string  t  = "test";
    char[]  c  = "test".dup;
    dchar[] dc = "test"d.dup;
    wchar[] wc = "test"w.dup;

    alias T  = CharEncodingType!(typeof(t));
    alias C  = CharEncodingType!(typeof(c));
    alias DC = CharEncodingType!(typeof(dc));
    alias WC = CharEncodingType!(typeof(wc));

    writeln( typeid(T), typeid(C), typeid(DC), typeid(WC) );

}





RESULT

$ ~/test_type
(ubyte,ushort,uint)(ubyte,ushort,uint)(ubyte,ushort,uint)(ubyte,ushort,uint)


instead of ubyte,ushort,uint

i will use your way ali

thanks for your useful code
