💡 Ideas to Improve openpdf-kotlin Module

1. Add Kotlin extension functions for common PDF tasks

   • 📄 Provide idiomatic Kotlin APIs like pdfDocument.addParagraph("...").
   • 📈 Benefit: Cleaner and more concise Kotlin usage.

2. Use Kotlin DSL for document creation

   • 🛠 Create a builder-style DSL for PDF generation (e.g., pdf { paragraph("Hello") }).
   • 📈 Benefit: Makes PDF creation more readable and expressive in Kotlin.

3. Add coroutines support for asynchronous PDF operations

   • 🧵 Wrap I/O-heavy tasks in suspend functions.
   • 📈 Benefit: Enables better integration with modern Kotlin apps using coroutines.

4. Improve null safety with Kotlin types

   • ✅ Replace nullable Java types with Kotlin ? syntax and smart casting.
   • 📈 Benefit: Safer code and better IDE support for Kotlin developers.

5. Write idiomatic Kotlin sample projects

   • 📚 Provide clean Kotlin examples in the examples/ directory or as a separate repo.
   • 📈 Benefit: Lowers the entry barrier for Kotlin users.

6. Add Kotlin wrappers for OpenPDF core classes

   • 🧩 Provide simplified Kotlin APIs for PdfWriter, PdfDocument, etc.
   • 📈 Benefit: Reduce boilerplate and increase developer productivity.

7. Publish multiplatform Kotlin targets

   • 🌐 Explore compatibility with Kotlin Multiplatform (JVM + Native/JS later).
   • 📈 Benefit: Enables cross-platform use (e.g., Android + Desktop).

8. Add unit tests written in Kotlin

   • ✅ Write tests in Kotlin to cover wrapper functions and DSLs.
   • 📈 Benefit: Ensures quality and demonstrates usage patterns.

9. Provide integration with Kotlin logging frameworks

   • 🪵 Integrate with kotlin-logging or SLF4J wrappers.
   • 📈 Benefit: Enables better debugging and diagnostics for Kotlin users.

10. Use Kotlin’s Result type for error handling

    • ⚠ Replace exception-heavy APIs with idiomatic Result<T> returns.
    • 📈 Benefit: Clearer error handling without deep try/catch blocks.
