Access Slack API's using Crystal.

slack:
  github: "manastech/crystal_slack"

You can get a Slack::SlashCommand from an HTTP::Request or its body:

require "slack"

request = HTTP::Request.new "POST", "/", body: "token=..."
command = Slack::SlashCommand.from_request(request)
puts command.text

You can create a message and send it using either webhooks or the chat.postMessage API:

require "slack"

message = Slack::Message.new("some_text", channel: "some_channel")

# send to webhook
message.send_to_hook "https://hooks.slack.com/services/..."

# send using the chat.postMessage API
api = Slack::API.new "some_token"
api.post_message(message)

More complex messages are supported. Please check the Message class. You can also get the users and channels given an token.

If you wish to configure the upstream slack host, you may do so

require "slack"

Slack::API.slack_host = "enterprise.slack.com" # Defaults to "slack.com"

Lots of API methods are missing!
