GoDoc Build Status Go Report Card

Skit is a simple tool/library written in Go (or Golang) for building Slack bots. Skit pre-compiled binary is good enough to build simple slack bots. For more complex usecases skit can be used as a library as well.


Simply download the pre-built binary for your platform from the Releases section.


Pre-compiled Binary

Release archive will contain a skit.toml file with some sample handlers setup. To run this default setup:

  1. Create a bot on slack by following Documentation
  2. Set slack token generated for the bot in skit.toml
  3. Run skit -c skit.toml
  4. Go to slack and find the bot which you created and chat!

skit.toml configuration file

Following skit.toml file can be used to setup a simple slack bot that passes any message sent to it to a shell script The output of this script will be sent back as the response.

token = "your-token-here"
log_level = "info"

name = "matcha_all"
type = "command"
match = [
cmd = "./"
args = [
  "{{ .event.Text }}"

See examples/ for samples of different handler configurations.

As a library

Following sample shows how to build a simple bot that echo's everything you say to it!

sk:= skit.New("your-token", logrus.New())
sk.Register("echo_all", skit.SimpleHandler("{{.event.Text}}",  ".*"))


A handler is an implementation of skit.Handler interface. A handler is responsible for consuming event, processing and responding to it when applicable. Currently 3 types of handlers are available.

1. simple

  • simple handler can be used to build simple regex based conversational bot.

  • Following sample shows how to configure simple handler:

    name = "simple_bot"
    type = "simple"
    match = [
      "my name is (?P<name>.*)"
    message = "Hello there {{ .name }}!"

2. command

  • command handler can be used to delegate the message handling responsibility to external command

  • This allows building bots which are more complex than the ones built with simple

  • Following sample shows how to configure command handler:

    name = "external_command"
    type = "command"
    match = [
    cmd = "./"
    args = [
      "{{ .event.Text }}"
    timeout = "5s"

3. lua

  • lua allows writing handlers using Lua script which will be executed using embedded Gopher-Lua

  • Lua code will have access to skit instance and its APIs and can be used build complex bots.

  • You can provide paths to be added to LUA_PATH as paths in the following config.

  • In the config sample below, source can be any valid lua code. So you can put your handler code in a file (e.g., handler.lua) under one of the paths and use source="require('handler')" in the handler config.

  • Following sample shows how to configure lua handler:

    name = "lua_handler"
    type = "lua"
    handler = "handle_event"
    paths = []
    source = """
      function handle_event(ctx, sk, event)
        sk:SendText(ctx, "Hello from Lua!", event.Channel)
        return true
