A simple way to wrap a string at different line lengths, optionally with indents.
e.g.
std::cout << Column( "This is quite a long string" ).width( 8 ) << std::endl;
will output:
This is
quite a
long
string
Columns can be combined, too:
auto a = Column( "This is a load of text that should go on the left" ) .width( 10 ); auto b = Column( "Here's some more strings that should be formatted to the right. " "It's longer so there should be blanks on the left" ) .width( 12 ) .initialIndent( 2 ); auto layout = a + Spacer( 4 ) + b; std::cout << layout << std::endl;
gives you:
This is a Here's
load of some more
text that strings that
should go should be
on the formatted to
left the right.
It's longer
so there
should be
blanks on
the left
Not bad!
You can also iterate the lines (which are generated lazily), both from Column and the combined Columns.
