[preprocessor] add pointer to T..
Hello, Thinking maybe little to late in the night at my end, but can see how to generate the following: T0* T0*, T1* T0*, T1*, T2* ..and so on Some variant on the below maybe..? Of course, below, you'd get T*0, T*1, etc if tried BOOST_PP_ENUM_PARAMS(n, T*) which doesn't produce a valid token. #include <boost/preprocessor/iteration/local/hpp> #include <boost/preprocessor/repetition.hpp> #define OPERATOR(z, n, _) \ \ BOOST_PP_ENUM_PARAMS(n, T) /**/ #define BOOST_PP_LOCAL_MACRO(n) OPERATOR(_, n, _) #define BOOST_PP_LOCAL_LIMITS(1, 3) #include BOOST_PP_LOCAL_ITERATE() #undef BOOST_PP_LOCAL_MACRO #undef BOOST_PP_LOCAL_LIMITS #undef OPERATOR All help appreciated. Cheers, -- Manfred

Thank you Joel, but how do I get the repetition across the other dimension? - I'm thinking I need something like a For-loop in there, so I get the rows of varying lengths.. Cheers, -- Manfred

Try: #define MAKE_TYPE(z,n,t) BOOST_PP_CAT(T,n)* #define MAKE_ROW(z,n,t) BOOST_PP_ENUM(n,MAKE_TYPE,~) BOOST_PP_REPEAT(10,MAKE_ROW,~)

I missed your need, you may just need to use BOOST_PP_FOR or BOOST_PP_ITERATE over your code calling the MAKE_TYPE in BOOST_PP_ENUM
Yes, ..trying that right now. However, if you or anyone else comes up with a solution, I'd be happy to see it. But I'll keep trying at this end. Thanks ever so much for your help to date. Cheers, -- Manfred

Hello Joel, turns out you got what I wanted in your first post to me, ..just it's so late in the evening here (quarter to 2 in the morning), that I forgot to put back-slashes on my macros.. (need, more of coffee, and sleep.. well I should do one or the other, can't do one, while I do the other). Thank you again Joel for bearing with me while I sorted myself out. Cheers, -- Manfred
You can also achieve this by using BOOST_PP_ENUM_BINARY_PARAMS and BOOST_PP_INTERCEPT to remove the second concatenated index: BOOST_PP_ENUM_BINARY_PARAMS(3, T, * BOOST_PP_INTERCEPT) which expands to...T0* T0*, T1* T0*, T1*, T2*Which will save you having to use the extra define.

Thank you Daniel - your suggestion has also now just proved useful. --Manfred On Mon, 31 May 2010 00:19:53 +0000 Daniel Bradburn <moagstar@hotmail.com> wrote:
