Kate on

Goodbye to Gitorious, welcome to

You can find the Kate project here.
The “Get It!” page on the homepage is updated, too.
Push access is still restricted, but that will not last for ever ūüėČ

Thanks to the sysadmin team of KDE, thanks guys, for all the work you put into the new infrastructure (and to help me with my faults ūüėČ
And thanks to Gitorious, it was a nice time there, and I learned to appreciate Git, like many Kate developers (some appreciated it even before).

Like before, all changes in SVN and Git will be synced by me, as Kate is still released with KDE SC from SVN.

For the future I would like (and most kate devs, too) to develop solely in the Kate repository and have Kate released from there with KDE SC (instead spread over several modules).
But this must still be discussed with the release team after 4.6.
Beside, this means no split off from KDE, but it makes contributing to Kate that much easier, given atm you would need to checkout/clone kdelibs + kdebase + kdesdk and try to build there the Kate relevant parts, which is just no fun, if you just want to hack on some small bug or feature :/

Kate git repository moving to soon!

We tried to move weeks ago already, but in our current repository some small glitches occured during the SVN => Git transition.
I have redone the conversion now and soon we will be on (if I not screw that again, thanks already to sysadmin for all help, now and in past!).
Still some small stuff will then need to be ported, which I will do after the initial repository is up there.
After this, the repository on Gitorious will vanish.

I will keep syncing KDE SVN and the repository, until KDE has migrated, too.
But please, if you work on features rather than simple oneliner fixes, use the git repository on after it is announced to be available.
You have automagically a git account and it makes merges for me much easier, if there are not too many conflicts from SVN -><- Git.

I hope the Kate team can keep the kate repository then as sole workspace, as working on the kate part/app is much easier for all contributors if you don’t have to get whole kdelibs/kdesdk. But that is still not discussed out I think, release team has a say here, as I would rather like to stay in KDE release cycle.

Kate Night-Make

Each night now Kate (part/app) is build from git and all unit tests are run. Yeah, we even got some tests .P
Until now, that just reminds on of our failures ūüėČ But I hope the daily mail will perhaps motivate me and others more to fix them ūüėČ

Beside, thanks for all the people working to write these tests, like Bernhard, Dominik and Milian.

Kate History ;)

While setting up the new server for the Kate homepage, I actually found again old stuff ūüėČ
Amazing that mails nearly ten years old can still be somewhere on the filesystem.
Perhaps a little hint, to post the beginnings of what today is Kate/KatePart/KWrite and KTextEditor.

Ten years ago, I asked the original author of KWrite, if he is interested in a MDI version of it (sorry, german, original mail):

From: Cullmann Christoph <>
Subject: KWrite - Verbesserungsvorschläge
Date: Thu, 14 Dec 2000 18:38:42 +0100

Ich benutze KWrite regelmässig um Quellcode zu bearbeiten und das
Syntaxhighlighting ist sehr praktisch.
Es wäre jedoch schön wenn KWrite eine MDI-Oberfläche hätte.
Ich baue gerade eine und falls jemand Interesse hat können sie sich ja melden.

Danke und Tschö
Christoph Cullmann

I actually never got any reaction from the author Jochen Wilhelmy. Guess the mail address was already abandoned at that time.
Later I tried my luck with kde-devel:

i am building a mdi texteditor using the kwrite-widget.
I want to use most of the extended features of the kwrite class, like search
dialog, kspell, ....

Is there any way to do this using the KParts system or must i use the kwrite
include files and compile the kwrite widget into my program ?

cu and thanks for any answer

Not much reactions, thought, but I kept to be persistent ūüėČ

Hi all,
I have build up a editor using the KWrite Widget and a QTabWidget to provide
a multidocument interface :-)
It has some bugs at the moment (I think QTabWidget is the problem) but works
real nice.

Anybody interested in this ?

Shortly after this mail, one of the developers which stayed around for years joined, Anders Lund (more at the team page).
I named the starting project “KCEdit” and put it up on

Date: Sat, 13 Jan 2001 12:04:33 +0100

Hi all,
I have build up a small mdi texteditor using the kwrite widget :-)
If someone is interested in helping to improve it or only wants to
test it a bit, i have set a project up.

url :

It would be nice if someone wants to take part in the development.


After that, the next nice guy joined: Michael Bartl.
We searched for a new name for the editor, as KCEdit was not that nice, as very similar to KEdit and no longer only “Cullmann”‘s pet project.
What did we choose? Here you see:

Here it is ;-)

As failed to be a nice hosting, we moved the project to (and later back again, lol).
Because of family problems Michael dropped out of the time after sometime, still BIG THANK YOU.

Later, I tried to get my changes back in KDE, as I didn’t want to do a permanent fork:

Subject: How can I participate in the KWrite project ?
Date: Tue, 20 Feb 2001 20:25:15 +0100

I want to help as a developer in the kwrite project. I and some other people
are working on Kant (, a MDI
texteditor for kde >=2.0 and we often find bugs in the kwrite code or missing
features we would need. It would be great if I could help to develop kwrite
because only sending bug reports and hoping that new features in kwrite will
come up sometime is really annoying.
How can I join the KWrite team and get CVS read/write access (perhaps ;-) ?
To have an overview about my skills please look at the Kant sourcecode or
simply download and test Kant out of the CVS at

cu and thx for you interest
Christoph Cullmann

Sorry for the bad English ;-)

Without much problems, I got a CVS account on the KDE server and was allowed to add my code and the code of the others to the KWrite codebase.
All other contributors which were still active got accounts later, too. Worked all like a charm thanks to Waldo Bastian.
Still Kant itself was not in KDE, therefor next try:

Subject: Could Kant replace or extend KWrite in KDE ?
Date: Sat, 24 Feb 2001 17:28:58 +0100

I am the projectmanager of Kant, a MDI texteditor which uses the KWrite
widget for displaying text (no MDI like you know it from windows, MDI like
you know it from Emacs or Konqueror :).

Kant has come to a level of stability which would it allow to put it into the
kde cvs i hope. I have talked with Carsten Pfeiffer (he likes Kant :) and he
told me to send a message to this list to start a discussion if and where
Kant could be integrated.

I just released a new Kant version (kant-0.2.0-prerelease) on
for testing the app that you have an overview about its features.

Kant Homepage:

newest Kant version to download:

nice screenshot of Kant:

If you want to look at the unstable development code just look into the Kant
CVS at, you find the exact description to checkout at the
Kant Homepage under "CVS" (cvs-modulename: kant).

Kant links dynamic to kwritepart and konsolepart. This must be considered if
you want to put Kant into kde cvs.

I hope you all like Kant, I think it would be a nice replacement for KWrite.

cu and thx

Sorry for my poor English and the big tar.gz file (something isn't right with
make dist in kant, must fix it :)

After some changes to the code, we were allowed to move the development completly to KDE CVS.
Joseph Wenninger joined the development, too.

Btw., my nice old e-mail footer:

Whereas Kant was just a fine name for us, it had some pronunciation in english which was not that political correct ūüėČ
Therefor we searched a new name:

Hi David,
would be Kate a political correct name for Kant ?

Kate - KDE Advanced Text Editor


We even asked the developers of Katy, an other text editor, if they would have problems with that name change ūüėČ
Kate was born ūüėČ
