Version 0.10 is released today. There is not much new in terms of functionality, but much of the code has been rewritten in preparation for a Windows port and much of it has been moved from C to JavsScript to make it tighter. Also new is the inclusion of SpiderMonkey in the tar.gz file to simplify installation.
Installation is made a lot easier by the efforts of OSSP, who have made a proper autoconf tarball out of spidermonkey: http://www.ossp.org/pkg/lib/js/
Thanks, guys! Jsext is updated to make use of their package, which contains the latest spidermonkey release, now with XML support according to the latest ECMA recommendations: http://www.ecma-international.org/publications/standards/Ecma-357.htm
Wrapping is now done through the highly intuitive C("#include <headerfile>","cache-file.so") syntax. All wrapping is now recursive, and double-wrapping is avoided by examining the symbols defined in previously included files.
jsext now supports fastCGI, either as a static or dynamic server. See jslib/fcgi.js and jslib/fcgi-wrapper for details.
jsext in version 0.8 is the first jsext release on SourceForge. Make sure to install spidermonkey (headers go in /usr/include/jsapi) before attempting to build!
