Hi,

I wonder if anyone could share his best practices as far as documenting Boost.Parameter enabled constructors is concerned. I'm currently doing something along the lines of

/** Construct from named parameters and use defaults where parameters are empty * * * \tparam Opts ArgumentPack of options. The following options are supported * - \a min_group_size minimum number of supporting correspondences to

form

a group. * - \a ntrials number of times to form basis from two randomly selected correspondences. * - \a bin_size_pos quantization size for transformed point coordinates. * - \a bin_size_orientation quantization in radians for surface orientation angles. * */ template<class Opts> group_geo_hash(const Opts &opts) { this->init( opts[Keywords::_min_group_size | 10], opts[Keywords::_bin_size_pos | LibFundament::rasFloat(10)], opts[Keywords::_orientation_rad | LibFundament::rasFloat(0.2)], opts[Keywords::_ntrials | 0]); } }

which is sub-optimal, because default values for options and option types are missing. Doxygen can deduce types for regular parameters as well as default values. Ideally this should work for boost.parameters as well :) Even better, Doxygen could warn about undocumented parameters.

I've used Doxygen tags WARN_IF_UNDOCMENTED and WARN_IF_DOC ERROR, and WARN_NO_PARAMDOC both in my doxyfile and in jamfiles - all =YES, sending the output to a named WARN_FILE = Boost_options_warnings.txt. This gives you a list of missing C++ Doxygen comments doc items if you are using Doxywizard (recommended at first because it is *much* quicker than running Quickbook toolchain). If the warnings file is empty, it is worth running the full docs :-) HTH - though I'm not sure it solves your real problem. Paul --- Paul A.
