The Go framework hanu is your best friend to create Slack bots! hanu uses allot for easy command and request parsing (e.g. whisper <word>) and runs fine as a Heroku worker. All you need is a Slack API token and you can create your first bot within seconds! Just have a look at the hanu-example bot or read my tutorial …
- Respond to mentions
- Respond to direct messages
- Auto-Generated command list for
help - Works fine as a worker on Heroku
Use the following example code or the hanu-example bot to get started.
package main
import (
"log"
"strings"
"github.com/sbstjn/hanu"
)
func main() {
slack, err := hanu.New("SLACK_BOT_API_TOKEN")
if err != nil {
log.Fatal(err)
}
Version := "0.0.1"
slack.Command("shout <word>", func(conv hanu.ConversationInterface) {
str, _ := conv.String("word")
conv.Reply(strings.ToUpper(str))
})
slack.Command("whisper <word>", func(conv hanu.ConversationInterface) {
str, _ := conv.String("word")
conv.Reply(strings.ToLower(str))
})
slack.Command("version", func(conv hanu.ConversationInterface) {
conv.Reply("Thanks for asking! I'm running `%s`", Version)
})
slack.Listen()
}The example code above connects to Slack using SLACK_BOT_API_TOKEN as the bot's token and can respond to direct messages and mentions for the commands shout <word> , whisper <word> and version.
You don't have to care about help requests, hanu has it built in and will respond with a list of all defined commands on direct messages like this:
/msg @hanu help
Of course this works fine with mentioning you bot's username as well:
@hanu help
Use direct messages for communication:
/msg @hanu version
Or use the bot in a public channel:
@hanu version
- github.com/sbstjn/allot for parsing
cmd <param1:string> <param2:integer>strings - golang.org/x/net/websocket for websocket communication with Slack
