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 #define MAKE_TYPE(z,n,t) BOOST_PP_CAT(T,n)*

BOOST_PP_ENUM(10,MAKE_TYPE,~)

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

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

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

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

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.
