And here is the second comment I wanted to put:
When parsing the options, you use an if-else. I don't know if
its just me, but I find that using a switch is clearer (it's
what you do in your second example). It also introduces string
cases (illegal in C++), and labeled control statements.
The code becomes:
import std.stdio : writef, writeln;
void main(string args)
args = args[1 .. $];
bool writeNewline = true;
size_t i = 0;
myForeach: foreach(arg; args)
writeNewline = false;
args = args[i .. $];
writef("%-(%s %)", args);
PS: If I figure out how to comment on your blog, I'll paste the
comments there :)
thanks for the info on writef, I didn't realise it could do that.
About the switch statement: I didn't even know you could do that
with labels, I'd only ever used them for gotos. I'll consider
putting that in the next version.
