Over two years ago, I announced that I had written a dictionary plugin for KRunner. Many expected it would be merged immediately, but there was an unfortunate hiccup. Because of the particulars of KRunner’s threading, and the fact that the dictionary data engine needed to only be accessed from the main thread, Aaron Seigo said that he would add an AbstractRunner property called setReentrant that would allow for easily accessing data engines from the KRunner’s match thread. This never materialized. I waited, and nothing ever came, and eventually I just presumed the plasma developers weren’t interested in adding this API themselves.

Not a problem, though. Now, two years since, I’ve decided to resurrect the runner, and rewrite it using mutexes to work around the API’s threading limitations. The result turned out very cleanly, and so far in my testing it works without fail.

It’s currently in kde-review, but I’m hoping to move it into plasma-addons and ship it with 4.10, now that it works well.

For the eager, you can try it out now with these commands:

svn co svn://anonsvn.kde.org/home/kde/trunk/kdereview/plasma/runners/dictionary dictionary-krunner
cd dictionary-krunner
cmake . -DCMAKE_INSTALL_PREFIX=$(kde4-config --prefix)
make
sudo make install

kquitapp krunner

    Nice to see there is such an interest.

    I have been also working on a dictionary and translator application for KDE Edu for about two years now (Mula in playground).

    We will provide a full-fledged translator and dictionary capability in KDE. :-)

    What about support for languages, as German?

  4. Fuchs says:

    Looks interesting and works here, unfortunately the main issue is, as with the dictionary plasmoid, that unless you can choose the language, it is quite useless for many people out there.

    There is a very old bug report against the dictionary plugin which has the same issue. Note that not everybody speaks english or only english, and would like to look up words in other languages.

    However, you are not the one to blame for that, so thanks a lot for this runner. It looks really interesting and brings a functionality that I missed since I saw it in OS X.

  5. By mutexes, does it mean it is callback friendly. Sorry, I’m more familiar with web terms :D

    I am sorry for the typo. Please accept my apologize for that.

  7. Johannes Huber says:

    How about moving to git?

  8. Migue Chan says:

    You need to install the packages:
    -build-essential
    -cmake

    Try again after installing those.

    there is a dataengine that provides access to stardict dictionaries:
