I would like to write to two files at once.

If user specifies verbose flag, output should write to both stdout and the programs standard output file.

Any ideas?

I should add, I'm using a library that already writes it's output to a std.stdout.File that I can provide it, so my thinking is I need a std.stdout.File that points at both stdout and some arbitrary file location.

Tricky I think...

What I ended up doing was creating an OutputRange that contains the files I want to write to.
On OutputRange.put I simply print to print to all the files.

Means I had to edit the underlying library, but that's OK as I own it, and this seems more robust anyway :)

If it is hardcoded to take a File (I.e. it's not a template parameter), then your options are: modify the library, modify phobos or use the OS to do the duplication. On *nix you should be able to do it quite easily, don't know about windows.

If I understand right you want to redirect the output to a file by a flag , another file type , video printer is it?

Just like MultiFile example here: :)

Yeah!
This is my implementation:
public struct OutputSink{
	File[] files;
	@property void addFile(File f){ files ~= f; }
	@property File[] file(){ return files; }

	void put(Args...)(string fmt, Args args){
		foreach(file; files)
			file.writefln(fmt, args);
	}
}

I'll remember to look in your book next time I need something simple :)

I think by video printer you mean the console?
If so, yes.

I believe I've solved it anyway, see Ali and my answer above.
Thanks!

You're right, Ali 's book is of great help for all
