Comments on: How to Adapt Templates as a Fusion Sequence

I really cann’t understand, why we need to transform data to fusion::vector . Why not contrary? Because type fusion::vector is built automatically by ‘>>’ and ‘qi::auto_’, but we want to have data .

Shortly: why transformation is data -> fusion::vector , but not contrary?

P.S. Excuse me if my English is not clear enough.

Olaf,
definitely. This was a typo in the code which is corrected now.

Thanks!

Is the

typedef fusion::vector type

correct? Isn’t it

typedef fusion::vector type ?

Thanks,
Olaf

Jeroen,

you’re right, fail() will be added with the next version only (Boost 1.43/Spirit V2.3), but it doesn’t hurt to define that function anyways, it just won’t be called.

Thanks!

I believe for backwards compatibility you should #include and wrap the fail function in a #if SPIRIT_VERSION >= 0x2030 .. #endif
