NetBeans Quick Tip #8 - Using Custom Folds




I have a friend who is a vim fanatic. You recognize his code by seeing many {{{ and }}} strings all over the sources. These strings are used to define custom folds in vim. They're just everywhere, it makes the code much less readable in other editors. Well, isn't this a typical example of user lock-in? ;-) If you're not using vim, sorry, your eyes have to skip all those {{{s.



Anyway, obviously folding seems to be an important issue for some of the people. Today's NetBeans tip is for all folding deviants. Did you know that next to usual NetBeans folds you can define custom folds? Maybe you've mentioned it in J2EE classes or in Swing forms, but in case you didn't here's a short explanation.



To add your custom fold, use following piece of text:


// <editor-fold>
Your code goes here...
// </editor-fold>



You can define default description of a collapsed fold like this:
// <editor-fold desc="This is my super secret genius code.">
Your code goes here...
// </editor-fold>



You can set a fold to be collapsed by default this way:
// <editor-fold defaultstate="collapsed">
Your code goes here...
// </editor-fold>



Happy folding!

    Hello from VIM fanatic ;-)

    but is not

    // {{{ <optional comment>

    your code ...

    // }}}

    simpler, smaller and cuter then some long XML tags? :-P

    You're right, it's shorter in vim ;-) But can you define description and default state in vim? I would be surprise if you would not...

    There seems to be a small bug. If you use :-

    <code>
    //<editor-fold desc="Start of auto generated elements" defaultstate="collapsed" >
    </code>

    The "defaultstate" is shown in the comment but if you use:-

    <code>
    //<editor-fold defaultstate="collapsed" desc="Start of auto generated elements">
    </code>

    It works correctly.

    Oh, yes, that's a bug. I've filed it.

    When will it be possible to just select a block of code and right-click on it, getting the option Create fold-block and have the XML-stuff generated by the IDE?

    Iwan, thanks for all your suggestions. Why don't you file them into Issuezilla as enhancements? This way people can vote for them and somebody might create a patch for these features... you can of course try to develop it yourself, too :-) Thanks.
