Seer Golang Client

The golang client for the seer forecasting server.

Installation

To install the seer client library, use go get

go get github.com/cshenton/seer-golang/seer

Usage

Since this is a client library, you'll need a server to communicate with. To get up and running just:

docker run -d -p 8080:8080 cshenton/seer

Check out the project repo over here

Then, to interact over localhost

package main

import (
        "log"
        "time"

        "github.com/cshenton/seer-golang/client"
)

func main() {
        // Create a client
        c, err := client.New("localhost:8080")
        if err != nil {
                log.Fatal(err)
        }

        // Create a stream
        _, err = c.CreateStream("myStream", 3600)
        if err != nil {
                log.Fatal(err)
        }

        // Add in data
        _, err = c.UpdateStream(
                "myStream",
                []float64{10, 9, 6},
                []time.Time{
                        time.Date(2016, 1, 1, 0, 0, 0, 0, time.UTC),
                        time.Date(2016, 1, 2, 0, 0, 0, 0, time.UTC),
                        time.Date(2016, 1, 3, 0, 0, 0, 0, time.UTC),
                },
        )
        if err != nil {
                log.Fatal(err)
        }

        // Generate and display forecast
        f, err = c.GetForecast("myStream", 10)
        fmt.Println(f)
}

(For Contributors) Generating gRPC Client stubs

protoc -I ../seer/seer --go_out=plugins=grpc:seer ../seer/seer/seer.proto

We then add //+build !test to the top of the file to exclude it from coverage statistics (since it has a tonne of redundant code, like the Get* methods and the server interfaces, which are not used, and therefore don't require testing).
