We list a few things you can do which are easy tasks and introduce you to Marble development. You can possible find some Junior Jobs at KDE's Bugzilla. Quality Assurance / Documentation We want our Marble source code to look good. The documentation should be concise and helpful and the comments shouldn't have spelling errors. Also it shouldn't have any obvious "formal" bugs. Help us to improve our code quality. This is an easy job that helps you to get familiar with the source code. It's the first thing that absolute beginners usually want to look at. We list a few important issues that need to be checked for regularly: Try to find spelling errors in the source code comments and in Marble UI strings. (EASY) KDE Krazy check: Have a look at the results of the static code checker: http://www.englishbreakfastnetwork.org/krazy/reports/kde-4.x/kdeedu/marble/index.html. Try to understand possible problems and create a fix for them. (EASY/MEDIUM) Get rid of compile warnings: Compile Marble from scratch and check all the warnings that possibly appear. Try to get rid of the warnings by adding fixes. If parameters are not used, examine why and either remove them or hide the warning or leave it as it is. (EASY-MEDIUM) Compile marble with the cmake option -DPEDANTIC=ON. Fix all errors that come up until Marble compiles through (MEDIUM). Add comments. You don't understand some source code in Marble? Then probably other people won't either. Try to understand it and ask Marble developers. The add some comments so that the next person will be able to understand the source code much easier (MEDIUM). Create API-Documentation (EASY). Review the API. Make sure that the API is Qt-ish (MEDIUM). Read http://qt.gitorious.org/qt/pages/ApiDesignPrinciples and read the Marble source code. Try to find cases which seem to be non-standard. (MEDIUM) Read our Marble Coding Standards: http://websvn.kde.org/trunk/KDE/kdeedu/marble/CODING?revision=700337&view=markup. Ensure that the Marble source code follows it (EASY). Help to translate Marble into your own language. Try to find "weird" translations or translations that don't express things in words that a normal user would understand and correct/report them (MEDIUM). Check KDE's Bugzilla for any open Marble bugs: https://bugs.kde.org/buglist.cgi?quicksearch=Marble. Try to reproduce the bugs and check whether the bugs are still valid. Remove them if they're not valid anymore and seem to be fixed already (EASY). Try to fix them if they are still valid (MEDIUM/HARD). If you come across a problem don't hesitate to ask us (there are no stupid questions, just people who are afraid of asking for stupid reasons ;-) If you want to send in your patch for review, please send it to our mailing list [email protected] KML This section deals with junior jobs that deal with Marble's data structure: Implement a "simple" tag for KML support (e.g. LookAt) The <LookAt> tag in KML should be quite easy to implement -- at least compared to the other tags. Alternatively you can try to find a different tag that looks like it would be easy to implement, however you need to check in the handler or data directory whether it is implemented already. Have a look at the KML reference: http://code.google.com/apis/kml/documentation/kmlreference.html#lookat Have a look at Marble's geodata source (in marble/src/lib/geodata). Try to understand what the parser, the handler and the data stuff does. Create a new handler (EASY) Connect Marble's MarbleMap::setLookAt() command to execute the lookat command Create an "Open Recent ..." menu entry In marble/src/KdeMainWindow.cpp use http://api.kde.org/4.x-api/kdelibs-apidocs/kdeui/html/classKRecentFilesAction.html to create an open recent menu entry for the KDE version of Marble. Adding the same functionality to the Qt version of Marble is a bonus task. Displaying Debug Info on request One could change the MarbleWidget::setTileId method to a MarbleWidget::setDebugInfo( DebugFlags ) method where DebugFlags is using QFlags http://doc.trolltech.com/4.5/qflags.html One could then set enable the qDebug messages by e.g. setting m_widget->setDebugInfo( DebugText | ShowTileID ); Level of difficulty: EASY Adding Bookmarks Gaurav is already working on this one. It would be nice if Marble had its own bookmark feature: Like in Konqueror you'd be able to click Bookmark->Add Bookmark and the current position and zoom value would get stored as a bookmark. Once the user would click the bookmark item the original coordinate and zoom value would get restored. You can use MarbleWidget::centerLongitude(), MarbleWidget::centerLatitude(), MarbleWidget::zoom() and the setters for the same properties to retrieve and set the coordinates. Level of difficulty: HARD Add more Plugin Icons Marble's plugin API lets plugins define an icon which is shown in the menu for activating plugins. Only a few plugins use icons so far however. Please locate appropriate plugin icons (chances are high the oxygen project already has some) and add them. A good start would be the Photos Online Service Plugin. Level of difficulty: EASY Add support for 23 to marble's Photos Online Service Plugin Marble's Photos Online Service Plugin currently displays photos downloaded from Flickr. As 23 also provides flickr API, it should be possible to display images from 23 as well. Bugzilla Level of difficulty: HARD add fast adding messurment points by ctrl+click See Bug 232098 for more information.
