libipuz is a library for loading and saving the ipuz data format for pencil-and-paper puzzles. It is written in C and Rust, and has dependencies on glib and json-glib. It is licensed under terms of the LGPLv2.1-or-later and the MIT licenses.

libipuz intends to have complete compatibility with the ipuz spec (local mirror), and areas where we don’t support something correctly are considered a bug. The areas where we have extensions or clarifications are documented here:

This library was primarily written for use by GNOME Crosswords. As a result, it only loads crossword-style ipuz puzzles. Other types are planned for the future.
