Description dlikhten 2010-05-21 18:17:47 UTC
I am unable to disable occurrence highlighting in Ruby.

The need arises from the fact that running on a low-powered PC, occurrence highlighting is destroying my editor's performance, even my ability to scroll through the text (left, right, a screen up, a screen down, etc). The performance is attrocious.

I am requesting that a toggle option is added to allow the disabling of this behavior for the ruby editor.

Also could help if the performance problems are looked into removing the need to disable this.

Hi Dmitriy,

Sorry for the late reply, I've been offline. It unfortunately isn't possible to turn off mark occurrences for Ruby. It would be straightforward to add such an option, at least a command line switch. Can you please file a bug for this (sounds like it should be a P2 at least)? We approaching code freeze for 6.9, but since adding an option for this is really low risk I think I'll still be allowed to do that for 6.9.

    Due to usage on my netbook, I would like to disable the Ruby occurrence highlighting feature of netbeans 6.8... (it is extremely costly performance wise, makes editing hard). How can I do this? I have the netbeans ruby bundle and there is no options under mark occurrences to disable ruby, in fact there are no options there at all.

I've added a system property for turning off mark occurrences in 



to netbeans_default_options in <nb_install_dir>/etc/netbeans.conf will disable the occurrence highlightning for Ruby. I'll need to add UI for this later, at this point I can't do any UI changes. Leaving the issue open until then.
