I am sure that it is a powerful library, but I really have no idea at all what is going on. I can't even parse the first line as valid C++ in any way. You need better examples, and also is that really the best way you could find to express repeating?
If I try to imagine what the interface would look like after taking into account some of the suggestions that were made, this sentence:
"Create data elements by mapping 1, 10, 100, 1000 by function f, and insert each result in cont by invoking modifier push_front."
translates to
( push_front<1>( cont ) % ( _data = f ) % ( _repeat = n ) )( 1, 10, 100, 1000 );
Questions : - is it more readable, now?
That is more readable.
Thanks.
- What if each example was preceded by its English equivalent. Is this a bit of stretch or a reasonable approach? I think this is a good idea. In general I think you can't over-explain basic examples.
OK, Thanks.
The style the library is using is still.. interesting. I'm still not sure why the '_repeat = n' comes in, and things seem attached strangely. I might perfer something that looked more like boost range's
make_range(1,10,100,1000) | f | push_front(cont)
I will answer this, but please note that I caused some confusion in answering Steward R. I just posted a correcting message, which perhaps will clarify where option ( _repeat = n ) was meant to achieve, in that case.
But, that might well not design as well as I think it would, or not do what you are suggesting.
