FunctionalPlus VS function2

Hoogle is really amazing!

Inspired by it, I implemented something similar for FunctionalPlus (a functional-programming library for C++): https://www.editgym.com/fplus-api-search/

I'd love to see more projects taking this path too. :)

A comparable library is FunctionalPlus

You can get a feel for it on its api search site: as an example, enter these queries:

I use a library called FunctionalPlus daily.

Any project CML file that is more complex than this is mismanaged and needs fixing asap. There is absolutely no reason to make CML files describing requirements of a library substantially more complex other than if you have a vendetta against yourself, package maintainers and your users.

FunctionalPlus - 30 lines for usage requirements + 60 for install rules: just simple commands creating a target, setting properties and defining install rules. Hmm, nothing unholy here.

You can copy this project structure: https://github.com/Dobiasd/FunctionalPlus

Fixed size function wrappers are not only limited and also a waste of space. Use a configurable function wrapper like fu2 with a stack allocator and set small object optimizer capacity to 0.

std::function wasn't cutting it for me, but I ended up going with fu2::function. It comes with a lot of features (almost too many), but the header size and compile times are comparable to , and it fit my needs pretty well.

Thank you, function2 is also used heavily in Idle as a type-erasure backend for continuable that is the primary asynchronous task abstraction.

You can write your own std::function, too, nor is it the only STL type that can take a capturing lambda (std::packaged_task for example).

A capturing lambda is just a class with an operator(). It's complicated to do what std::function does, but fully possible.

In fact, custom std::function replacements have better lambda support than std::function itself. Such as unique_function in https://github.com/Naios/function2 which can handle non-copyable lambdas.
