`pneumatic`

pneumatic is a library providing lazily evaluated functional programing to Go. The API is meant to be quite similar to Rust's std::iter::Iterator trait. Working in Go professionally, one of the things I find irksome is a lack of declarative programming. The primary goal for this library is simply to be an exercise in generics and functional programming, making my (and hopefully your) Go experience better.

Note that while you and I both love using declarative, functional code, it is generally considered unidiomatic in Go. Consider your project's style guide before deciding whether pneumatic is right for you.

import "github.com/skubalj/pneumatic"

evenSquares := pneumatic.NewFromSlice([]int{1, 2, 3, 4, 5}).
    Map(func(x int) int {return x * x}).
    Filter(func(y int) bool {return x&1 == 0}).
    Collect() // => []int{4, 16}
