history
Project history and usage
chmlib is a small C library and set of utilities for reading Microsoft ITSS/CHM Html Help files.
Project history
The upstream README for CHMLIB 0.40a says the library was designed for accessing MS ITSS files, the format used by Microsoft Html Help .chm documentation, and supports archive lookup and reading but not writing. The GitHub source tree was imported in 2006 at version 0.37, while the NEWS file records earlier 0.2, 0.3, 0.32, and 0.35 release history.
Adoption history
The README credits portability work across Linux, Win32, OS X, Solaris, IRIX, Windows CE, MinGW32, x86-64, and ia64, plus Debian package maintainers. The input package facts show modern distribution through Homebrew, Debian/Ubuntu, Fedora/DNF, MacPorts, Nix, Arch, and openSUSE.
How it is used
The package provides library functionality and command-line utilities such as chm_http, enum_chmLib, enumdir_chmLib, extract_chmLib, and test_chmLib for inspecting, serving, and extracting CHM archives.
Why package nerds care
chmlib matters to package maintainers because it is old, small infrastructure for a proprietary documentation container format. Its utilities and library bindings let Unix systems index, extract, and view legacy Windows help files without the Microsoft runtime.
Timeline
- 2002: README credits Solaris and IRIX portability work.
- 2006: Official GitHub source tree imported at 0.37.
- 2006: NEWS records security fixes around 0.36 and 0.37 and later 0.40 maintenance fixes.
- 2026: Homebrew packages chmlib 0.40 from the jedrea.com source tarball.
Related projects
- The README names Microsoft Html Help, ITSS, IStorage-style archive access, Stuart Caie's LZX decompression code, and chm_http as an included helper utility.
