Hi all, I've just committed the version of Wave (V1.2.4) which will be part of the upcomming Boost release. It has a bunch of new features in it (with kind approval by Thomas Witt) and some bugfixes applied making it worth to have a look at: - automatic include guard detection - full interactive mode of the Wave tool, now you can use the Wave tool just like Python or Perl for instance to interactively try out your BOOST_PP macros - load/save macro tables to store the state of interactive sessions (that's implemented using the Boost.Serialization library) - performance improvements by upto 30-40% - new pragmas allowing to control certain library features from inside the preprocessed sources (partial output redirection, control of generated whitespace and #line directives) - and bunch of fixes For a full list of changes please look at: http://boost-consulting.com/boost/libs/wave/ChangeLog Feedback is as always welcome!
