[Preprocessor] ternary identity macro
Hello, I often write something like #define TEXT(z, n, data) data BOOST_PP_ENUM(5, TEXT, xxx) in my code to create a comma separated list of words. Is there already a macro like TEXT in boost? Or is there a even better way to do what I want? Thanks in advance

There is BOOST_PP_ENUM_PARAMS. BOOST_PP_ENUM_PARAMS(5, xxx) Roman Perepelitsa.
Sebastian, I think to get the desired effect will need to use BOOST_PP_INTERCEPT to suppress the number: BOOST_PP_ENUM_PARAMS <http://www.boost.org/doc/libs/1_49_0/libs/preprocessor/doc/ref/enum_binary_params.html>(5, SomeText BOOST_PP_INTERCEPT <http://www.boost.org/doc/libs/1_49_0/libs/preprocessor/doc/ref/intercept.html>) Regards Daniel Bradburn 2012/4/24 Roman Perepelitsa <roman.perepelitsa@gmail.com>
