Dear,
i do not understand what is wrong in my code and produce this:

-------------------------
$ ldc2 ../../lib/libdscience-ldc.a -I=../.. fasta.d
/usr/include/d/std/range.d(295): Error: static assert  "Cannot put a
Sequence into a LockingTextWriter"
    instantiatied in /usr/include/d/std/format.d(1512):
put!(LockingTextWriter,Sequence)
    instantiatied in /usr/include/d/std/format.d(1869):
formatRange!(LockingTextWriter,Sequence,char)
    instantiatied in /usr/include/d/std/format.d(2232):
formatValue!(LockingTextWriter,Sequence,char)
    ... (1 instantiations, -v to show) ...
    instantiatied in /usr/include/d/std/stdio.d(684):
formattedWrite!(LockingTextWriter,char,Sequence)
    instantiatied in /usr/include/d/std/stdio.d(1563):
write!(Sequence,char)
    instantiatied in fasta.d(12): writeln!(Sequence)
-------------------------


sequence file can be show here: https://gitorious.org/dscience/dscience/blobs/master/dscience/molecules/sequence.d


thanks

Just by reading the code, LockingTextWriter can "put" only the dchar type. This is from std.stdio:

        /// Range primitive implementations.
        void put(A)(A writeme) if (is(ElementType!A : const(dchar)))
// ...
        void put(C)(C c) if (is(C : const(dchar)))

I haven't tried it myself, but changing the return type of Sequence.front() to dchar would work.

I was wrong anyway. I think is(C : const(dchar)) means if C can implicitly be convertible to dchar. That is the case for char and wchar, so that can't be the reason.

Sorry, no more ideas here. :(
