PR: Improve Error Handling in CodeChunker

Summary

This pull request improves error handling in the CodeChunker class by replacing an assert statement with a proper RuntimeError exception. This change ensures that library users receive clear, actionable error messages when the parser fails to initialize, rather than an ambiguous AssertionError.

Details

• File: src/chonkie/chunker/code.py
• Change:
  • Replaced:

    assert self.parser is not None, "Parser is not initialized."

    with:

    if self.parser is None:
        raise RuntimeError("Parser failed to initialize. Language detection or initialization failed.")

• Reason:
  • Assertions are intended for internal logic errors and can be disabled with Python's -O flag.
  • Raising a specific exception provides clearer feedback to developers using the library and allows for better error handling downstream.

Impact

• Improves developer experience for all users of the CodeChunker class.
• No breaking changes to the public API.

Summary of Changes

Hello @anaslimem, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request refines the error handling mechanism within the CodeChunker class by transitioning from an assertion-based check to a more robust exception-based approach. This change ensures that any issues with parser initialization are communicated explicitly through a RuntimeError, providing developers with precise feedback and improving the overall reliability and usability of the library without altering its public API.

Highlights

• Improved Error Handling: Replaced an assert statement with a RuntimeError exception for parser initialization failures in the CodeChunker class.
• Enhanced Developer Experience: Library users will now receive clearer, actionable error messages when the parser fails to initialize, facilitating better error handling downstream.

Code Review

The pull request effectively improves error handling by replacing an assert statement with a RuntimeError exception. This change is beneficial as it provides clearer and more robust error feedback to users, aligning with best practices for library development where assertions are typically reserved for internal logic checks that should never fail in production. The change is well-justified and implemented correctly.
