I have what looks like a perfect application for Boost/Preprocessor. I have 192 entries in a Factory Map a portion of which are show below. I'd like to generate the permutations of the three macro inputs, but can't figure out where to start. Any help would be appreciated.

#define MAP_ENTRY_MCR( aLang, aType, aAcc ) \ \ mMap[ CKey( aLang, aType, aAcc ) ] \ = CVarX< aLang, aType, aAcc >::Make;

MAP_ENTRY_MCR( DCTlanguageC, DCT_DOUBLE , DCT_NONE ); MAP_ENTRY_MCR( DCTlanguageC, DCT_DOUBLE , DCT_INIT ); MAP_ENTRY_MCR( DCTlanguageC, DCT_DOUBLE , DCT_ANYTIME );

MAP_ENTRY_MCR( DCTlanguageC, DCT_FLOAT , DCT_NONE ); ...

Thanks, Jeff Flinn

Hi Jeff,

I want to make certain that I'm clear about what you're trying to do. You have 192 consecutive "MAP_ENTRY_MCR( ... )" with different permutions each time, right? How many different elements for each "field" do you have? (i.e. how many DCT_DOUBLE, DCT_FLOAT, etc. and how many DCT_NONE, DCT_INIT, etc.)

aLang(4) => DCTlanguageAda, DCTlanguageAdsim, DCTlanguageC , DCTlanguageFortran aType(8)=> DCT_DOUBLE, DCT_FLOAT , DCT_INT_16, DCT_INT_32, DCT_INT_8 , DCT_UINT_16, DCT_UINT_32, DCT_UINT_8 aAcc(3)=> DCT_INIT, DCT_ANYTIME, DCT_NONE This accounts for 96 MAP_ENTRY_MCR's. There will actually be a 4th macro argument: aDim(2)=> DCT_Vector, DCT_Scalar Which accounts for the 192 entries. The DCT_ constants are a combination of enums and integer defines. aLang and aDim are enum entries, with sequential values starting with 1. aType and aAcc are integer defines. aType is non-sequential, aAcc is sequential starting with 1. It is possible for any of these to become non-sequential in the future.

There are several ways to do this, so let me know if I'm clear on what you're doing, and I'll help you.
