[Boost-users] [format] Alternative syntax

[Emre Turkay]

Hi folks,

Any interest in the alternative syntax for boost::format?

format2 f("Hello %s, %s");
std::cout << f("Joe", "Jane") << std::endl
<< f("Jose", "Mary") << std::endl;

Which creates the output;

Hello Joe, Jane
Hello Jose, Mary

Code is available at http://bit.ly/2J60Re for any suggessions.

Take care,

emre

Why is this syntax better?

I like that syntax, and I can see how it could be better in that it
would have better caching (does not need to recreate the object, which
is very slow), and it is a more simple syntax then the normal way you
can cache it. Looks nice to me.

format f1("%s, %s");
string s1 = (f1 % arg1 % arg2).str();

format2 f2("%s, %s");
string s2 = f2(arg1, arg2);

I don't claim it's better in general, the first case is better in places
where you need to bind the arguments one by one. And I think the second
case is easier to read and understand and therefore it is better in places
where you can bind all the arguments at once and need the formatted
string immediately.

Take care,

Well, thanks. Apparently, removing the extra copy of the boost::format
object does not change the functionality, so it is removed.
