README

Loop Development Kit (LDK) for Go

The LDK is a plugin system for Sidekick. The LDK is built with go-plugin, a HashiCorp plugin system used in several of their projects.

Plugins developed with this library are executed by Sidekick as separate processes. This ensures that crashes or instability in the plugin will not destabilize the Sidekick process.

Communication between Sidekick and the plugin is first initialized over stdio and then performed using GRPC. On mac and linux the GRPC communication is sent over unix domain socket and on windows over local TCP socket.

In order for Sidekick to use a plugin, it must be compiled. Sidekick does not compile or interpret source code at runtime. A consequence of this is that plugins will need to be compiled for each operating system that they want to support.

Installation

go get -u github.com/open-olive/loop-development-kit-go

Usage

Full documentation available on GoDoc.

Controllers

This LDK can be used to write controllers for Sidekick. More detail about controllers is available here.

Sensors

This LDK can be used to write sensors for Sidekick. More detail about sensors is available here.

Development

protoc

The LDK utilizes protoc to create the protobuf that defines the contract that is utilized by GRPC.

  • Install protobuf with Homebrew brew link protobuf
  • Make your changes to proto/ldk.proto
  • Then generate the new protobuf file with make proto/ldk.pb.go

Since proto/ldk.pb.go is auto-generated, do not edit this file directly.
