           Summary: Justified Tuple printing
           Product: D
           Version: D2
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: minor
          Priority: P2
         Component: Phobos
        AssignedTo: nobody puremagic.com
        ReportedBy: bearophile_hugs eml.cc



import std.stdio: writeln, writefln;
import std.typecons: tuple;
void main() {
    auto s = "hello";
    writefln(">%40s<", s);
    writefln(">%-40s<", s);
    auto t = tuple("hello");
    writefln(">%40s<", t);
    writefln(">%-40s<", t);
}


dmd 2.063alpha prints:


                                   hello<
hello                                   <
Tuple!(string)("hello")<
Tuple!(string)("hello")<



But maybe it should print:

                                   hello<
hello                                   <
                 Tuple!(string)("hello")<
Tuple!(string)("hello")                 <

--------------------

Note: currently this code doesn't give an error, I don't know if this is
correct:


import std.stdio: writefln;
void main() {
    auto s = "hello";
    writefln(">%-s<", s);
}


It prints:

hello<
