Gettext
Gettext is an internationalization (i18n) and localization (l10n) system used for translating software applications into multiple languages. It provides a framework for extracting translatable strings from source code, managing translation files (like .po and .mo), and integrating localized text at runtime. Widely adopted in open-source projects, it supports various programming languages and platforms to enable multilingual software development.
Developers should learn Gettext when building applications that need to support multiple languages, as it offers a standardized and efficient way to handle translations. It is particularly useful for open-source projects, web applications, and desktop software where community contributions or professional localization are required. Use cases include internationalizing websites, creating multilingual desktop apps, and managing translations in large-scale software projects.
