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, double>::type

and you get

boost_::mpl::vector

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
