botstack

This is a base project for creating FB Chatbots. It has a state machine and User Management and allows you to add functionality with modules.

Quickstart

Put all your logic into lib/bot. We've already prepared everything for you to kickstart your project.

@msg_meta holds @request_type holds the type of the request. Could be one of the following:

• DELIVERY (maybe will be removed in the future, to disruptive)
• OPTIN
• CALLBACK
• TEXT
• IMAGE -> @msg_meta has the url to the image
• LOCATION-> @msg_meta has the long / lat
• AUDIO -> @msg_meta has the url to the mp3 file
• ATTACHMENT_UNKNOWN -> @msg_meta has the url to the ATTACHMENT_UNKNOWN (mostly http links fucked up with fb outbound link system) @current_user hold infos of your current user (last seen, state machine, user id ...)

Reply Module

This function will reply a message back to the user who sent one. you can use Spintax and Emojs.

 def reply_message(msg, options={})

 def example()
  reply_message "make {:pizza:|:sushi:|:lemon:} great again!"
 end

This function will send an image back to the user who sent a message to your bot.

 def reply_image(img_url)

This function will render HTML and send an image back to the user who sent a message to your bot.

 def reply_html(html)

This function will render a bubble and send it to the user.

 def reply_bubble

This function will return a string along with a set of button options specified in an array.

 def reply_quick_buttons(msg, options=%W(Yes No))

This function will return a string containing the message a user sent to your bot.

 def get_message

Emoji Module

Most of the time you will not need the Emoji Module because it is already integrated into the reply module.

This function will return the UTF-8 representation of the given Emoji Name

 def get_emoji(name)

This function will send a reply message with the UTF-8 representation of the given Emoji Name

 def reply_emoji(name)

This function will be always used with the reply_message function of the repy module. It will search for emoji names surrounded with : and replaces them with the UTF-8 representation of the given [Emoji Name]

 def compute_emojis(content)

This function is the opposite of the function above.

 def parse_emojis(content)

Web Search Module

With the web search module you can transport websites to messengers. Just add two methods to your bot logic. One for handling search requests and one for handling user input on the search results.

search_request_on_website(
	url: "http://www.example.com/",
	form_name: 'search',
	result_css_selector: '.result > a',
	image_css_selector: 'img',
	button_text: 'more infos'
)

handle_search_result(
	url: "http://www.example.com",
	result_css_selector: ".result"
)

State Machine Module

This Module will help you with guiding users through different states of your bot.

Example usage of the State Machine Module:

class BotLogic < BaseBotLogic

	def self.bot_logic
		state_action 0, :greeting
		state_action 1, :turorial
		state_action 2, :bye
	end

	def self.greeting
		reply_message "greeting"
		state_go
	end 

	def self.turorial
		reply_message "turorial"
		state_go
	end 

	def self.bye
		reply_message "bye"
		state_reset
	end 

end
