Data Recovery in 4.10

Recently I’ve blogged about the usage of KMessageWidget in the data recovery process in Kate Part. Finally, we decided to stick with KMessageWidget, since it is a standard kdelibs widget, used by a lot of KDE applications. Besides, it is visually appealing and attracts the user’s attention. In KDE SC 4.10, it will look like this:

Now if you recover the data, it may happen that the swap file is broken, e.g. because it was accidently manipulated for whatever reason. Then you get notified like this:

Besides that, we are currently at our Kate/KDevelop meeting in Vienna. Lots of exciting stuff is happening, so expect more in the next days :-)

Project Plugin, Current State

After some days of more hacking on the plugin, there current state is already nice for my daily use.

A simple file like

     "name": "Kate"
   , "files": [ { "git": 1 } ]

defines already the complete project for the kate.git.

If you open any file with Kate inside your local kate.git clone (and the project plugin from master branch is loaded), Kate will auto-open the project and highlight the file you just opened there in the tree. No need to think about opening some project in the menu, just open the file you want to start working at and start. The project plugin won’t get into your way or require additional steps.

It will allow you nice and fast file switching between your project files in the filesystem tree like structure without any noise of non-git tracked files ;) Still the normal “Documents” view is around like it used to be, if you want to just navigate between currently opened files.

If you modify the project file, the project will auto-refresh itself, still a reload button is needed to trigger e.g. reparsing of git files, if your add/remove files and want a fresh project tree. The auto-reload won’t help there, as is is more or less a nop if the project file content was unchanged.

The “Search and Replace” plugin will integrate nicely and per default will do project wide searches, if any project is currently active (you can switch to other search modes like before in the combobox, just the default is changed, if the project plugin is active). Thanks to Kåre’s nice design of the plugin, this addition was really easy to implement.

Exuberant Ctags integration is work-in-progress. At the moment on project load, a background thread will generate a ctags index (after it has constructed the file tree from git/svn/…) and the auto-completion will use this index for all files associated with your project. An additional toolview, that allows you to search inside the index will be implemented, too. It is a bit like the current ctags plugin, but without any setup or manual indexing ;) For the kate.git, the indexing (in the background) needs less than half second, even for kdelibs frameworks branch it is only 2-3 seconds. On Kate exit the index files (created as temp files in your local temp directory) will vanish again. No index database polluting your checkouts/clones or homes.

Will try to add more features I like for my daily work, if you have any ideas to improve the plugin, just let me know here or on ;)

Project Management, Take Three

After bit more playing around with the project plugin, I did get aware that I am even to lazy to open project files. Normally if I need to fix something or add new features, I just go to the directory and open the source or build system files I need to work on.  Therefore the project plugin now just watches which files you open and will load the corresponding project on the fly for you ;) (instead of naming your project, you create a .kateproject hidden file in the toplevel project dir, just like Git would do it with its .git directory)

Next issue that arised: even with the simple pattern syntax like:

"files": [ { "directory": "kate", "filters": ["*.cpp", "*.h", "*.ui", "CMakeLists.txt", "Find*.cmake"], "recursive": 1 } ]

it is hard to enumerate all files in the kate.git, as we have .py files, .xml files, .desktop files, .sh files and so on.

As I started here locally to add more and more extensions, I got the impression that just asking Git would be an better idea, and voila:

"files": [ { "directory": "kate", "git": 1, "recursive": 1 } ]

and you get recursively all files that are registered in your Git clone in the kate directory ;)

If you still have SVN, no problem, for your project this will work:

"files": [ { "directory": "kate", "svn": 1, "recursive": 1 } ]

These extensions make creating your Kate project much easier I guess and avoid any battling with regular expressions to keep track of the important files.

Other improvements:

  • Current file will be selected correctly in the projects view
  • Search and Replace is enhanced with an “in Project” option, if the project plugin is loaded and any project active, for this a bit work was needed to allow inter-plugin communication ;)

And again, the mandatory screenshot:

RFC: Data Recovery

Currently, we use our own passive notification bar to show a recovery bar when a swap file was found:

Since version 4.7 we have a class called KMessageWidget (api documentation). Using KMessageWidget, the notification could also look like this:

Imo, the new one looks nicer, as it much better distinguishes the notification popup from the rest of the ui. However, it several drawbacks:

  • the minimum width is now 800 pixel due to the label (too large, might break layout in apps)
  • the title “Data Recovery” was omitted
  • the “Help” link, showing a tool tip with further information, can not be added anymore (the api does not allow it)

Possible solutions:

  • put the buttons under the label, as it was in the old version (currently, the api does not allow it, so we’d need something like setButtonsUnderText(bool))
  • wrap the text in the label (looks aweful, since the buttons appear then between two lines of text)
  • to get the “Help” label back, the api would need to forward the QLabel’s signal linkActivated(const QString&)

I’m not sure whether the API can be extended in the 4.x line, though…
