Line Modification System

Some days ago, Dominik implemented a line modification system in the KatePart.
For all who don’t know what that means at all (like me before the DS 2011), here some screenshots.

First, starting with a fresh loaded file:

Now, lets write some lines:

Next, after saving:

Now, lets change some stuff again:

Awesome :)

First I thought: Why to hell do I need such a feature? But after using it some days now, I think it is really VERY useful.

Yesterday I worked in parallel on code that generates integer linear programs as CPLEX files and read the output files (which are > 100000 lines) to find regressions.
I had to manually tweak the ILP files a bit to reveal the reason of my issues and it was just cool to exactly know even after save, which lines in the ILP I touched.
Normally I would have written some comments like \changed… above my modified lines in the output files, but yeah, KatePart does track such stuff now automatically ;)

Even for the much less big source files, it was nice to see:
Oh, I just tweaked that few C++ lines and it did remove the issue, maybe I should look at the lines below/above of that lines, too, for more possible problems?

Therefor: Thanks to Dominik for this nifty feature, I hope others appreciate it, too!

If you want this feature now: Use the guide at’s Get It!. Updates

After adding the new design to the Kate homepage, I got some feedback about broken fonts and other stuff. Most should be fixed now, e.g. the “The Team” page now looks kind of okay again.

In addition, we now have some nice feed display with the latest commits and overall a bit cleanup page. For mobile devices, like my Android phone, we now have WPtouch installed, which provides some rather nice layout for small screens (but allows easy switch back to normal layout, too).

If you have any additional comments, what could be changed, just write me a comment or a mail.
