C++ dataflow programming library for hard real-time controls and DSP

We have open sourced a compact and simple dataflow programming library in C++ intended for hard real-time embedded systems as well as general-purpose applications. It is dependency-free, single-header-only, and runs anywhere out of the box. Behold the Real-time Actor-based Message Exchange Network :

Here’s the idea:

               ┌────────┐
       (float) │ Summer │ (float)
 in_a ◄────────┤        │◄──────── out_sum
               │        │
       (float) │        │
 in_b ◄────────┤        │
               └────────┘

struct Summer
{
    ramen::Puller<float> in_a;
    ramen::Puller<float> in_b;
    ramen::Pullable<float> out_sum = [this](float& out) { out = *in_a + *in_b; };
};

A detailed walkthrough with examples is available from the repo.
