Interesting. Should I do the same in phobos?
stdout("wyda");
I'd like that particularly because write() is too common a name to place
at namespace level for my taste. So then we'd have:
stdout("wyda"); // no newline
stdout("wyda\n"); // newline but no flushing on binary stream
stdout("wyda", newline); // write'n'flush
stdout.writeln("wyda"); // same
If we go that route I'll even drop writeln and rely on passing newline.
For formatting there'd be stdout.format and stdout.formatln or something.
This is funny because Tango has adopted exactly the same design.
The only difference is that Stdout is written in upper case:
import tango.io.Stdout;
void main() {
Stdout("Hello, World\n"); // no flushing
Stdout("Hello, World").newline; // new line appended, flushs
Stdout.format("Hello, {}!", "Andrei").newline; // formatting
Stdout.formatln("Hello, {}!", "Kris");
}
It would be great if the two libraries share the same interface.
BTW, since you are in process of redesigning of Phobos IO/stream system, it
would be great if you take a look at the Tango IO system, first. I recall you
telling that you didn't give a good look at Tango, so now is the time. I
particularly insist on talking to Kris about it; perhaps, he has some ideas on
the topic. He may also share experience with you (errors he made etc). I'll
give you a few ideas of mine in a separate post.
You shouldn't avoid looking on someone's code, especially if it may help D get
better standard library. There's nothing wrong with borrowing ideas from
others, too, especially if they give you a permission for that. Tango is
dual-licensed under Academic Free License v3.0 and BSD License, so there might
not be a need to, but anyway.
Back on topic, in most cases I use:
debug writefln("hello");
because I have no console in release version (and it throws when there
is no stdout, look in the bugzilla for a bug report). It is already
long enough, so I wouldn't like it to be even longer:
debug stdio.writefln("hello");
My 0.02 rubles.
Got them.
