- There are several common mistakes that prevent applications from being properly localized. Find out what they are and how to easily avoid them in this tutorial.
- Building KDE's Localization Module
- Building and installing language support from KDE's localization (l10n) module is a good idea for those working on applications in the main KDE repository. Doing so will allow you to test your application in another language and spot problem areas. Learn how to do just that in this tutorial.
- Incorporating i18n Into the Build System
- Once your application is ready to be localized, the next step is to ensure that translation files are built automatically and kept up to date. This tutorial covers the necessary CMakeFiles.txt additions as well the process of distributing the resulting message catalogs with your application.
- Common i18n Challenges and Solutions
- This tutorial covers challenges that you may eventually run into such as translating handbooks and other data that exists outside of the source code, merging and handling obsolete .po files, dealing with freezes, coding in languages other than English and creating independent releases of or moving applications between KDE modules.
- Semantic Markup of Messages
- To ensure consistent presentation and more meaningful representations of messages in applications, semantic markup can be applied to messages marked for translation using the KUIT system. This tutorial describes how this system works.
- Automated i18n Code Checking
- The Krazy code checker scans KDE's code and reports common i18n mistakes.
- Dealing with Language Changes
- This tutorial covers dealing with changing languages: How to add the function to change the language and then dynamically update the user interface when language has been changed.
- Understanding How Messages Appear to Translators
- An introduction to what context information is extracted (and what isn't) from source code for translators to see.
