    .desktop file

    In order to find your language support plugin, KDE needs a .desktop file with some meta information.

    • X-KDE-Library=... this must be the same as the name of your library, i.e. look into the CMakeLists.txt for your kde4_add_plugin line and use the same name
    • X-KDE-PluginInfo-Name=... this must be a unique name that is used to reference and find your plugin.

    After installing your plugin, make sure to run kbuildsycoca4. For testing, try duchainify or ktraderclient.

    the plugin

    A basic plugin's header looks like this:

    #include <interfaces/iplugin.h>
    #include <language/interfaces/ilanguagesupport.h>
    
    class KDevTestLangPlugin : public KDevelop::IPlugin, public KDevelop::ILanguageSupport
    {
        Q_OBJECT
        Q_INTERFACES( KDevelop::ILanguageSupport )
        public:
            explicit KDevTestLangPlugin( QObject* parent, const QVariantList& args = QVariantList() );
            
            virtual KDevelop::ParseJob* createParseJob(const KDevelop::IndexedString& url);
            virtual QString name() const;
    };
    

    An implementation could look like this:

    
    #include "kdevtestlangplugin.h"
    #include <KPluginFactory>
    #include <KAboutData>
    
    #include "testlangparsejob.h"
    
    K_PLUGIN_FACTORY(KDevTestLangSupportFactory, registerPlugin<KDevTestLangPlugin>(); )
    // note: "kdevtestlangsupport" must be the same as you used in X-KDE-PluginInfo-Name!
    K_EXPORT_PLUGIN(KDevTestLangSupportFactory(KAboutData("kdevtestlangsupport","kdevtestlang", ki18n("TestLanguage Support"), "0.1", ki18n("Support for Some Test Language"), KAboutData::License_GPL)))
    
    using namespace KDevelop;
    
    KDevTestLangPlugin::KDevTestLangPlugin(QObject* parent, const QVariantList& )
         : IPlugin( KDevTestLangSupportFactory::componentData(), parent )
         , ILanguageSupport()
    {
        // NOTE: this is important!
        KDEV_USE_EXTENSION_INTERFACE(ILanguageSupport)
    }
    
    ParseJob* KDevTestLangPlugin::createParseJob(const IndexedString& url)
    {
        return new TestLangParseJob(url, this);
    }
    
    QString KDevTestLangPlugin::name() const
    {
        // some unique id for your language
        return "testlang";
    }
