Hi,

Can someone give me a clue on why nothing is printed to stdout ?

I wish a list of files with their size.

code:
//
import std.stdio;
import std.file;

void main(string[] args)
{
    foreach (DirEntry e; dirEntries(".", SpanMode.shallow))
    {
        writeln(e.name, "\t", e.size);
    }
}
//
Build with (dmd2):
dmd -w test.d

Works for me on 2.055 and 2.056 on windows. What compiler and OS are you using?

c:\temp>dmd -w test.d
c:\temp>test|more
.\.a.d.un~      5326
.\.asciidoc_user-guide.txt.un~  942
(...)

Tested with dmd 2.055 and now 2.056 on Linux

My aplogies it you already know this, It's not my intention to be patronizing: You did run the resulting executable, right ( ./test )? And there are files in the dir its beng run from?

And you did run it in a DOS window or from a batch file with a PAUSE to allow you to read the output ;-)

I might be way off on this.
Yet this silly stuff used to catch me all the time when switching from windows to *nixes, back and forth:

sh$: compile something to 'test'
sh$: test
no output - WTF? Ahem, it just called that command line tool named  test...
sh$: ./test
wow, now something happens ;)

Don't need to apologize, it's already kind to answer ;)
So, Yes I run the resulting executable in my $HOME dir where there are
many files.

If I run it through Geany (IDE) I only got:
------------------
(program exited with code: 1)
Press return to continue

If I run in my terminal, there's no output.

Oh I remember doing that too :)  Don't feel bad, everyone does this at least once.  I hate that stupid test builtin, nobody ever uses it anymore.

Note, it's not a command line tool, it's a shell builtin, which is why it overrides anything in your search path.

I've since adopted the habit of calling test programs "testme" instead of "test" :)
