Question:
How can an online platform dynamically detect and display text in Right-to-Left (RTL) or Left-to-Right (LTR) languages?
Answer:
To dynamically detect and adjust text direction on your platform, lightweight and open-source options include:
- CLD2: A backend solution detecting languages (like Arabic or Hebrew) to infer RTL direction.
- Franc: A frontend or backend language detection tool that can identify RTL languages and adjust direction.
- lre-detection: A lightweight JavaScript library that directly detects RTL or LTR based on character sets, ideal for on-the-fly detection.
- CSS: For inputs, use
unicode-bidianddirection: autoto auto-detect text direction.
Implementation:
Use lre-detection for real-time detection, or combine Franc/CLD2 with server-side detection for broader language support, dynamically setting the dir attribute in your HTML.
