Color Settings

This week, Kate Part received an update of the “Colors” tab in the settings dialog, available in KDE 4.9. The major features include

  • configurable colors: search highlight, replace highlight and modified line colors – finally :-)
  • possibility to always use colors from the KDE color scheme.
  • the implementation works in a way that at some point, the host application (KDevelop, Kile, …) can put items into this list.

Here are screenshots of the new (top) and the old (bottom) color tab:

The new implementation uses a QTreeWidget along with a custom delegate to draw the colors button and reset icon. It would be nice to have an appearance of the categories like in systemsettings, or like in dolphin. Dolphin probably uses a KCategorizedView, which in turn uses KCategoryDrawer. KCategoryDrawer could be used, but needs fine tuning in order to make it look nice. Does someone know how systemsettings draws the nice shaded backgrounds of the categories?

Scripting in Kate

Since several releases, Kate Part has scripting support through javascript. So far, it seems it is not much used by users. Still, I stumbled over two extensions:

If you have more user defined scripts, it would be nice if you let us know! For KDE5, we plan to extend this, so applications like Kile or KDevelop can reuse Kate’s internal code.

On another note, here is a nice blog about the upcoming KDE 4.8 release :-)

Highlighting Search & Replace Matches

In response to Kate in KDE 4.8, there was this reply on reddit:

Does this mean the stupid search/replace functionality has finally been fixed?

Once the search/replace marks/colors text there’s no way to clear it so when you’re replacing keywords the last one will be permanently marked with background color unless you reload the file or search for something else… Infuriating.

It’s about the yellow / green background for search matches / replace items. But stating that you have to reload the file in order to remove the highlighting is completely wrong. If you dislike the persisting highlighting, just press ESC, and it is removed (yes, this is by design, and imho very useful).

There is a pretty good book called The pragmatic programmer, and one rule of thumb is

Use a Single Editor Well

The editor should be an extension of your hand; make sure your editor is configurable, extensible, and programmable.

How true! :-)
