Flowbot - A Flowdock robot written in Go

This is a library to create a Flowdock robot which runs in Golang.

Overview

It uses the following Flowdock APIs:

• Stream API (to read content on a given flow),
• Push API (to push chat message on the flow or a team inbox notification).

Installation

$ go get -u github.com/eko/flowbot

Run the robot

$ go run app.go
Connecting to Flowdock stream https://stream.flowdock.com/flows/[...]/[...]
Connected! Start reading stream...
-> Command found: flow uptime
-> Chat message correctly sent.

A robot example application

This sample application answers to the following commands:

• flow uptime: Renders the server uptime,
• flow image : Render the first image found on Google Image corresponding to

package main

import (
    "github.com/eko/flowbot"
    "fmt"
    "io/ioutil"
    "net/http"
    "os/exec"
    "regexp"
)

func main() {
    flowbot.FlowdockFlowToken = "<YOUR FLOW TOKEN API KEY>"
    flowbot.FlowdockStreamUrl = "https://stream.flowdock.com/flows/<YOUR-ORGANIZATION>/<YOUR-FLOW-NAME>"
    flowbot.FlowdockAuthUsername = "<YOUR EMAIL ADDRESS>"
    flowbot.FlowdockAuthPassword = "<YOUR PASSWORD>"

    flowbot.AddCommand("flow uptime", func (command flowbot.Command, entry flowbot.Entry) {
        output, err := exec.Command("uptime").Output()
        if err != nil { panic(err) }

        flowbot.SendChat(fmt.Sprintf("My uptime: %s", output))
    })

    flowbot.AddCommand("flow image (.*)", func (command flowbot.Command, entry flowbot.Entry) {
        query := command.Pattern.FindStringSubmatch(entry.Content)[1]

        response, err := http.Get(fmt.Sprintf("https://ajax.googleapis.com/ajax/services/search/images?v=1.0&q=%s", query))
        if err != nil { panic(err) }

        body, _ := ioutil.ReadAll(response.Body)

        imagePattern := regexp.MustCompile(`(http[s]?://[a-zA-Z0-9\/\-\.\_\%]+.[gif|png|jpg|jpeg])`)
        image := imagePattern.FindStringSubmatch(string(body))[0]

        flowbot.SendChat(image)
    })

    flowbot.Stream()
}
