           Summary: Unexpected BufferedFile output
           Product: D
           Version: 2.040
          Platform: x86
        OS/Version: Windows
            Status: NEW
          Severity: normal
          Priority: P2
         Component: Phobos
        AssignedTo: nobody puremagic.com
        ReportedBy: bearophile_hugs eml.cc



This D2 code:

import std.stream: BufferedFile, FileMode;
import std.conv: to;
void main() {
    auto fout = new BufferedFile("foo.txt", FileMode.Out);
    int x = 10;
    fout.write(to!(const(char)[])(x) ~ "\n");
    fout.close();
}


Generates this foo.txt file (bytes expressed in hex):

03 00 00 00 31 30 0a



This Python2.6 program:

fout = file("foo.txt", "w")
fout.write(str(10) + "\n")

Generates this foo.txt file:

31 30 0d 0a


So I don't know if the D code gives the right output.

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

Secondary problem, this line:
fout.write(to!(const(char)[])(x) ~ "\n");
can't be replaced by this simpler one, that doesn't work:
fout.write(to!string(x) ~ "\n");

The second problem is now fixed, this code compiles, see bug 2718 :


import std.stream: BufferedFile, FileMode;
import std.conv: to;
void main() {
    auto fout = new BufferedFile("foo.txt", FileMode.Out);
    int x = 10;
    fout.write(to!string(x) ~ "\n");
    fout.close();
}
