I'm writing a program to take a file and convert it into a binary format which
matches the format produced by a system which we use.  If I get it right, this
will allow me to "replay" the file into the system.  However I can't find how
to do I/O in D.  I've got the "D Programming Language" and "Tango" books, but
not much there, and as a C/C++ programmer, Tango doesn't seem that appealing
:-).  Is there a tutorial anywhere?
Thanks

in case you did not find some example code yet: http://www.dprogramming.com/FileTutorial.html

Thanks.  Not sure how I didn't find that - I'm looking now. Graham

Is this D 1.0 ? I get errors regarding printf - I understood that writeln was the
2.0 way.
Thanks

Yes, I think it's D 1.0. For a D 2.0 version I replaced those printf's with writeln's, too.

Bye,
Tom

File/path I/O is kind of a pain in Tango. You might want to consider D2/Phobos for that: http://www.digitalmars.com/d/2.0/phobos/std_file.html

If you want to use D1/Tango though, the API reference is here: http://www.dsource.org/projects/tango/docs/stable

Weren't streams converted to ranges?

Not yet. std.stream as it is is going to be deprecated/removed. However, the Phobos team does not yet have a replacement for it (which will be a range-based stream solution). I believe that there's at least one implementation floating around which might make it into Phobos, but nothing has been approved yet for inclusion.

I'm getting a little confused.  I've installed a .deb package of d 2.0, but now my
code won't compile:
unlogcat.d(112): Error: std.stream.File at
/usr/include/d/dmd/phobos/std/stream.d(1787) conflicts with std.stdio.File at
/usr/include/d/dmd/phobos/std/stdio.d(248)

Yet if I leave either out, I get unresolved symbols.  Also, where can I find out
what exceptions can be raised for a particular operation ?
Thanks

Your code probably is including both stdio and stream.  Then you use the simple type File, which is defined in both.

Try disambiguating by using std.stdio.File or std.stream.File.

Or alternatively, you can rename imports (don't remember the exact syntax).
