Gettext is an internationalization (i18n) and localization (l10n) library for Elixir applications. It provides macros for marking strings in source code that need translation, extracts these strings into POT (Portable Object Template) files, and merges them with PO (Portable Object) files for different locales. At runtime, it looks up translations based on the current locale and supports features like pluralization, context-based translations, domain-specific messages, and string interpolation with compile-time optimization. The architecture follows a library pattern with clear separation between the API (Gettext module), backend behavior (Gettext.Backend), compilation (Gettext.Compiler), extraction (Gettext.Extractor), merging (Gettext.Merger), and specialized components for interpolation, pluralization, and fuzzy matching.
This is a monorepo for General Translation (GT), a comprehensive internationalization (i18n) and localization (l10n) platform. It provides runtime libraries for React, Next.js, Vue, React Native, Node.js, and Python frameworks, enabling developers to translate entire React components—not just strings—using a simple `<T>` wrapper. The platform includes a CLI for extracting translatable strings from source code, uploading them to a translation service, and downloading completed translations. A Babel/SWC compiler injects translation hashes at build time, and a Sanity CMS plugin manages document-level translations. The architecture is a multi-package monorepo with shared core types, a compiler pipeline, framework-specific adapters, and a cloud API client. The codebase demonstrates high craftsmanship with clean abstractions like condition stores, singleton caches, batch processing utilities, and a step-based workflow pattern. It is actively maintained with extensive test coverage and modern tooling (pnpm, Turborepo, TypeScript, Vitest).
