Hey @bvqbao!

Thanks for opening an issue 😊

Yes, we actually had this in mind for Chonkie's future releases! Though at this may take some time to add as it's not an immediate priority at the moment~ We want to focus on getting the core chunkers of Chonkie to be stable, adding additional chunking methods, and offering support to greater input modalities first (e.g., Markdown, PDF, JSON etc.). We definitely plan for code chunking before the v1 stable release, however, and possibly even in Q1/Q2 2025.

I hope you continue to support Chonkie as it grows. :))

Thanks~ ☺️
