Code & Placeholders

Localazy automatically identifies and highlights placeholders within your source text, making them visually distinct for translators.

When translating, placeholders like variables, HTML tags, and formatting codes appear specially marked, preventing accidental modification. Our system also performs validation checks that detect if a placeholder is missing or modified in the translation, alerting translators immediately rather than letting errors slip through to your application.

For developers, this means far fewer runtime crashes and formatting issues caused by broken placeholders in translated text. You won’t need to manually verify that every %s, {variable}, or HTML tag has been preserved correctly across dozens of languages - Localazy handles this verification automatically, letting you focus on building your product rather than debugging localization issues.

Format Conversions support placeholders across various formats, but their syntax can differ between platforms. For example, in Android, placeholders are typically in the format %1$s, while in iOS, they use %@. Localazy automatically converts these placeholders to the appropriate format for the target platform, ensuring that your translations work correctly without manual adjustments.

Localazy’s placeholder detection system works with virtually all common placeholder formats used in software development. This includes HTML/XML tags, React-style JSX elements, iOS and Android string format specifiers (%s, %d, etc.), ICU MessageFormat patterns ({name}), JavaScript template literals, printf-style formatting, and custom variable patterns specific to different frameworks and languages.

The system is designed to be framework-agnostic, so whether you’re using Angular, React, Vue, iOS Swift, Android Kotlin, or any other technology stack, Localazy will automatically recognize your code elements. This flexibility means you don’t need to modify your existing code patterns or add special markup for Localazy to understand what needs protection during translation.

If the placeholders in your project are not supported, feel free to contact us, we constantly expand the detection with new syntax.
