           Summary: std.stdio.File + ternary = bug
           Product: D
           Version: D2
          Platform: Other
        OS/Version: Windows
            Status: NEW
          Severity: normal
          Priority: P2
         Component: DMD
        AssignedTo: nobody puremagic.com
        ReportedBy: dsimcha yahoo.com



I haven't been able to reduce this far enough to know for sure whether this is
a DMD or Phobos bug, but the following ternary operator expression should work:

import std.stdio;

void main() {
    bool foo;
    auto lines = (foo ? File("test.d") : File("test.d")).byLine();
    writeln(lines.empty);  // true

    auto handle = File("test.d");
    lines = handle.byLine();
    writeln(lines.empty);  // false
}

This is not a bug. The test actually works if the file "test.d" exists
beforehand.
If it doesn't exist, one must open the file in write mode. By default, the file
is open in read mode.
This works as intended.

import std.stdio;

void main() {
    bool foo;
    auto lines = (foo ? File("test.d", "w") : File("test.d", "w")).byLine();
    writeln(lines.empty);  // true

    auto handle = File("test.d");
    lines = handle.byLine();
    writeln(lines.empty);  // false
}
