Hi,
I've built interactive shells for preprocessor and template metaprogramming. I've been using them for development and debugging of metaprograms and I think Boost developers could also find them useful.
You can type in (metaprogramming) expressions which get evaluated and the result is displayed immediately. For example you can type
boost::mpl::push_front<boost::mpl::vector<int, char>, double>::type
and you get
boost_::mpl::vector<double, int, char>
as the result (the boost_ namespace is used because there are some tricks there to make the output more readable).
As an example for the preprocessor shell you can type
BOOST_PP_REPEAT(3, foo BOOST_PP_TUPLE_EAT(3), ~)
and you get
foo foo foo
as the result.
The tools are based on the Boost.Wave library and Clang. You can get them here: Preshell for preprocessor: https://github.com/sabel83/preshell Metashell for template metaprograms: https://github.com/sabel83/metashell
You can also try them from your browser here: http://abel.web.elte.hu/shell
Feedback is welcome.

FANTASTIC! I tried the above example in my ubuntu Konqueror browser and it worked as expected: /* * Template metaprogramming shell 1.0.0 * 9f2271f Keep link path at install * * Metashell Copyright (C) 2013 Abel Sinkovics (abel@sinkovics.hu) * This program comes with ABSOLUTELY NO WARRANTY.

Thank you very much Abel. -kind regards, Larry
