You can turn on colours to see what state your documentation is in.
Select the "Outdated Docs" option in the "View" menu to turn colour
coding on and off.
The colours themselves are user settable. In the above picture you will
see some text is red, some is blue, and some is black. Red text represents
things that have no documentation. The public, protected, and private
tags represent the documentation state of the class itself. Blue fields
have docs, but the docs haven't been updated since the object has changed.
For example if you document a method, but then add a variable, those docs
will be out of date. The black text represents documentation that is up
It's actually pretty hard to keep your docs up to date as just about
any change to anything will turn it orange. However it is a
reasonable goal to get rid of as much red as possible. And of course
you can always turn the colour coding off when it gets annoying.
