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.


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 -> @msgmeta has the url to the image * LOCATION-> @msgmeta has the long / lat * AUDIO -> @msgmeta has the url to the mp3 file * ATTACHMENTUNKNOWN -> @msgmeta has the url to the ATTACHMENTUNKNOWN (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. ```ruby 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 replymessage 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] ```ruby def computeemojis(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.

    url: "",
    form_name: 'search',
    result_css_selector: '.result > a',
    image_css_selector: 'img',
    button_text: 'more infos'

handle_search_result( url: "", 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: ```ruby class BotLogic < BaseBotLogic

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

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 ```
