This section contains information about tools for KDE development.
Debugging and Analysis
A list of tools which are used to analyze a program. This includes debuggers and profilers, for instance.
- Valgrind helps to find memory leaks and uninitialized memory blocks. Additional features are a profiler and more. Valgrind is one of the most important development tools!
- The GNU Project Debugger (GDB)
- GDB helps in debugging source code. As GDB evolved over time it is recommended to use version 6.x. Graphical frontends are available (see below). See also the debugging tutorial Debugging with GDB.
- KDbg is a graphical user interface to GDB, which is able to set breakpoints, step through the code etc.
- KDevelop is an excellent IDE for developing KDE and Qt C++ applications. It includes a an integrated debugger, a powerful editor with syntax highlighting, a Project wizard to create applications from templates, the automake/autoconf gunk, and even the class documentation. Further details can also be found in the KDevelop wiki.
- Instructions on how to use KDevelop with KDE 4 applications is available at this page
- Qt Designer
- With Trolltechs Qt Designer it is easy to layout user interfaces like buttons and checkboxes. Additional features are undo/redo, checking accelerator conflicts etc. Qt Designer allows even non-programmers to help design KDE dialogs. Further details can be found in the tutorial Using Qt Designer and in the Qt documentation.
Internationalization (i18n) Tools
- KBabel is a set of tools for editing and managing gettext PO files. Its main part is a powerful and comfortable PO file editor which features full navigation capabilities, full editing functionality, possibility to search for translations in different dictionaries, spell and syntax checking, showing diffs and many more.
- Also included is a "Catalog Manager", a file manager view which helps keeping an overview of PO files. Last but not least it includes a standalone dictionary application as an additional possibility to access KBabel's powerful dictionaries. KBabel will help you to translate fast and also keep consistent translations.
- Dr. Klash
- This little utility, once activated, can present a report about conflicting shortcuts in menus. Not only this is helpful for translators but also for developers. A little hand editing of `kde-config --localprefix`/share/config/kdeglobals activates this feature:
- Now pressing F12 will show a dialog containing which accelerators in the currently focussed interface conflict and provide suggestions for new accelerators. If no accelerators conflict or Dr. Klash has nothing to suggest, no popup dialog will not be displayed at all.
- With AutoCheckAccelerators enabled the dialog will popup automatically if a conflict exists and AlwaysShowCheckAccelerators can force the dialog to always popup even if there are no conflicts to report.
- The XX language
- This helper language serves as a debugging aid for people finding untranslated strings in applications. If you start your application with the ``xx locale, all translated strings will appear with x's. First you have to check out these ``translations from l10n/xx and install them.
- After you've built l10n/xx and installed it, run your application using the XX locale. This can be done by launching it from the command line like this:
> KDE_LANG=xx kspread
- This will start KSpread using the XX locale no matter what your current language setting is. Look for strings that do not have the x's in them. If x's are missing from a string, it could be due to missing i18n calls or even missing or incorrectly generated .pot files. Consult the i18n tutorials for further information.
- When checking for untranslated strings, be sure to check all the WhatsThis help and tooltips.
Examining .po files
You can look at the translated .po files to see if a string is present and has been translated. For example, here's a portion of l10n/de/messages/kdebase/konqueror.po:
#: konq_mainwindow.cc:3707 konq_tabs.cc:84
msgid "&New Tab"
msgstr "Neues &Unterfenster"
The string to be translated is given on the msgid line. The translated string is on the msgstr line. Notice that the exact same string to translate came from konq_mainwindow.cc and also from konq_tabs.cc. This saves the translators from having to translate the same identical string twice.
You can also use KBabel to examine .po files. KBabel is part of the kdesdk module.
- Get information about KDE's installation - kde-config
- The tool kde-config helps to find out more about a KDE installation.
- Driving Konqueror From Scripts - kfmclient
