This code runs on ideone: http://ideone.com/iSBBO But not here, 32 bit, Linux, dmd 2.058 with:


/usr/include/d/std/conv.d(101): Error: template
std.format.formatValue(Writer,T,Char) if (is(Unqual!(T) == bool))
formatValue(Writer,T,Char) if (is(Unqual!(T) == bool)) matches more than one
template declaration,
/usr/include/d/std/format.d(1342):formatValue(Writer,T,Char) if
(!isSomeString!(T) && isDynamicArray!(T)) and
/usr/include/d/std/format.d(1978):formatValue(Writer,T,Char) if
(!isSomeString!(T) && (is(T == struct) || is(T == union)))

Don't link to an external site, because it may be disappear in the future. Instead write code directly, or attach the testcase, please.

> http://ideone.com/iSBBO

import std.string;
import std.stdio;

struct S {
    ubyte[] metadata;

    string toString(){
        return "%s".format( metadata );
    }
}

struct Foo {
    S[] bar;
    alias bar this;

    string toString(){
        return "%s".format( bar );
    }
}

void main(){
    S   s;
    s.metadata = [0,1,2];
    Foo foo;
    foo.bar = [s];

    writeln( foo );
}

This test case with 2.059head does not raise errors, but std.format still has an issue.

Reduced test case:

struct Foo {
    int[] bar;
    alias bar this;
}
void main()
{
    import std.format;
    import std.array;

    auto w = appender!string();
    FormatSpec!char f;
    Foo foo;
    formatValue(w, foo, f);    // OK
    formatValue(w, Foo(), f);  // NG
}
