CHM libraries for Python

• pychm wraps the CHMLib C library. The high-level CHMFile class finds the title, home page, table of contents and index, reads pages, and runs searches against the CHM’s built-in full-text index; the low-level chm.chmlib module mirrors the C API, including enumeration. It needs CHMLib installed. GPL-2.0-or-later, in maintenance mode.

Without native dependencies, you can also extract a CHM with the 7z command (subprocess.run(["7z", "x", "help.chm", "-oout"])) and parse the extracted .hhc table of contents with an HTML parser. The archmage tool, built on pychm, converts CHM to HTML or PDF.
