A long time ago, I had one and was intending *eventually* to add it to iostreams, but never got around to it. It's in:

Thank you. Al though google revealed some postings about margin_ostream it failed to get me to the sources. I am not sure however you noticed the difference to my implementation: I am storing state _in_ the stream, i.e. in ios base member and thus allowing out << indent_in << "blah blah\n"; out << "still indented\n"; And a function void foo(ostream& os) that gets passed down my indent_filter'ed stream still knowns the indentation status. The margin_ostream implements indent operation only the stream object. Does is also have manipulators? Will margin_ostream also work when downcasted to a plain ostream? -- _________________________________________ _ _ | Roland Schwarz |_)(_ | aka. speedsnail | \__) | mailto:roland.schwarz@chello.at ________| http://www.blackspace.at
