What is this header for? It defines, just to give an example, equal_to: namespace ranges { /// \addtogroup group-functional /// @{ struc ...

Godbolt: Here input is a contiguous, non-common, non-sized range. range-v3's take_last(n) doesn't work on such ranges, because its strategy is simp ...

I'd like to rangify the following code, which checks for the first occurance of a sequence of unique characters: I came up with the following, that ...

I want to declare a function, that gets a range as input, outputs a single number and use it directly with ranges::views::transform of the range-v3 li ...

I am using the following concepts to identify a map-like type, but it causes a cryptic error within the range-v3 v.0.12 library when used with GCC-11 ...

I have the following code fragment using ranges::v3: I get the following errors It appears to be complaining about the absence of a suitable ove ...

I am trying to use ranges-v3 to split an SNMP OID into parts and return them as a std::deque<uint32_t>. The following code works but only after ...

I find the traditional syntax of most c++ stl algorithms annoying; that using them is lengthy to write is only a small issue, but that they always nee ...

I'm trying to parse a Wavefront OBJ file. If line describes a vertex, i try to split it, take XYZ-coordinates, and assign them to a tuple. For example ...

I'd like to have a generator that terminates, like python, but I can't tell from ranges::views::generate's interface if this is supported. ...
