Recent Files Menu in Kate

As many other applications Kate has the menu File > Recent Files, which lists all files you recently used. This recent file list right now is per session, i.e., each session has its own entries listed as recent files. Now there is a request to change it such that there is just one single global recent file list. I think having two recent files menus (one for the session and one global) is a bad solution. Further, adding an option for that also sounds wrong.

To change or not to change, that’s the question?! :) What do you think?

File Tree plugin and Kate in KDE SC 4.6

Hi! It’s me again. Got some exciting news.

The file tree is now the default (and only) document list/view widget. It actually took me by surprise. After I got the list mode and other features implemented, the old document list was unceremoniously ripped out, and extensions were added to allow kate to always load a given plugin, and give its settings tab a little more prominence.

Since then however I’ve fixed a few issues regarding the settings in the plugin. The file tree settings tab now sets the plugins global settings, and will clear out the setting overrides for the current session so they will get pulled from the global settings. And I just finished up adding back the “Go” menu, and the “next” and “prev” document shortcuts.

Just to be clear, you are NOT forced to use a tree view from now on. That is just the current default. You can switch to list mode using either the settings dialog (which will apply to kate globally, minus any sessions you have used the document view context menu to change the mode for), or using the context menu on the document view (file tree) widget.

Thank you to everyone who has used my plugin in the past, and to everyone who will be using it in the future :)

Introducing Kate GDB Plugin

Have you, like me, had to switch to an external debugger or run raw gdb in the terminal plugin to debug the C/C++ application you develop with Kate? That might not be necessary any more. There is now a “GDB Plugin” in trunk that gives you the power of raw GDB with some QAction candy for the most common actions.

I have always been a bit frustrated with not having a debugger directly in Kate, but too lazy/busy to start a debugger plugin project. Fortunately Ian Wakeling started this GDB plugin and got it off the ground. When I got introduced to it at Akademy, it triggered an itch in me to get this plugin into kdesdk and to add some features for the more point and click type of persons. As it seemed I had a bit more free time to spend on the plugin, Ian let me take over as maintainer.

Main features of the plugin:
- Jump to the corresponding file and line whenever gdb stops.
- Insert and remove breakpoints.
- Tool-bar buttons for the most often used actions like step into/over/out. Those actions can of course also be assigned to keyboard shortcuts.
- Execution markers and breakpoint markers on the icon border.
- A call stack tab for point and click navigation of the call stack.
- Optional IO redirection to a separate tab.
- Printing the value of the currently selected variable or expression. QStrings and friends are not supported (yet?).
- And last but not least. A GDB console for the full power of GDB.

And now the screen-shots

Kate Tree View Plugin Update

It’s me again. Given how much people seem to like the plugin, and that some would like to see this plugin replace the existing simple list view, I’ve put in a bit of work to make it so the tree view plugin replaces as much functionality of the original file list as possible.

There’s now a list mode (which was surprisingly easy to do), as well as the tree mode and I’ve extended the sorting support to include all but the “custom sort order” option of the original file list (it’ll take a bit more work to support that, if its something people actually use, I just haven’t felt like doing the work to get drag and drop to work, and before now it didn’t make much sense to add). While I was at it I also added a Settings Dialog Page for the plugin.

One improvement (imo) over the old file list, is that all tree view settings are session specific. Each session saves its own sorting, view mode, and item highlighting color settings.

Now for some gratuitous screen shots:

Here we see the new sort order context menu items, pretty dull so far.

Now it starts to get a little more interesting. The view mode context menu!

Ooh, and now we can see it displaying in list mode!

Again in list mode, but sorted by the document’s path, rather than just by document name.

And here’s the new config page. Nothing much to look at, but it works :)

I still have a couple more things I want to add, like a fancy way to filter and eventually, if everyone’s agreeable, I’ll thief the back/forward actions, and the “Go” menu from the main file list.

Before I go, I was wondering if people would be willing to help me with some distro packages, I might be able to manage some Debian packages, but I’m not sure when I’ll get to it so if anyone is willing and capable, have at it.

Thats all for now. Thanks for reading :)
