Hi Bertolt, sorry for a belated reply, but here it goes anyway.
2. I don't think that passing line width as construct parameter to options_descripton is optimal. It's not really property of options description. A better design would be do only line_width parameter to the options_description::print method. What do you think?
But this would mean no more oprator<< for options_descripton! Not a real problem but existing code like
os << desc;
would have to be changed to
desc.print(os, line_length);
If you want i can make that change but the question is do you really want to? (Assuming a default line_length for oprator<< does not really look right to me.)
I think default line length will work for a large percentage of users, and to make output with non-default line_length convenient we can introduce a new function: os << line_length(desc, 40) which will create a special object that will call 'print' with the right parameters. What do you think? Regardless of what we decide on the above, your patch is almost finished, so I've just committed it. Thanks for the work and your patience!
3. Do you plan to add detailed formatting description. If you don't have
the
time now, no problem, I'll commit the patch anyway.
I plan to do. But probably not before new year.
No pressure, but still would be nice ;-) - Volodya
