proto

proto gives Go operations like Map, Reduce, Filter, De/Multiplex, etc. without sacrificing idiomatic harmony or speed. It also introduces a convenience type for these functions, Proto, which is a stand-in for the empty interface (interface{}), which is used to box values being sent to these operations.

Documentation

Please see documentation.{txt,html} for the automatically generated documentation - or better yet, just run:

godoc github.com/eblume/proto | less

That's probably a better idea since there's a decent chance the documentation might be lagging behind the current code base, since it has to be run manually (at this moment).

You can also take a look at the *_test.go files for an even better look in to how to use Proto. I will make one disclaimer, which is that code written with Proto has some unavoidable boilerplate in the form of casting to/from the Proto type - this boilerplate is annoying but is much less obvious and significant with larger code bases that use Proto-style channels in chains.

Examples

Double every integer in a slice:

inputs := []Proto{0, 1, 2, 3, 4, 5, 6}
sent := Send(inputs)
doubler := func(a Proto) Proto {
    return a.(int) * 2
}
mapped := Map(doubler, sent)
doubled := Gather(mapped)

Double every integer, chained:

doubled := Gather(Map(func(a Proto) Proto {
    return a.(int) * 2
}, Send([]Proto{0, 1, 2, 3, 4, 5, 6})))
