Webwatch

Introduction

This is a demo beginners project for ZuriHac 2016. It watches a certain webpage for links with keywords (e.g. search http://news.ycombinator.com for "Haskell"). When such a link is found, it sends you a slack message. See the codelab for more details.

Code layout

The code is organised in three modules.

  • WebWatch.Links: Scrapes a web page and pulls out links matching given keywords
  • WebWatch.Slack: Performs a HTTP POST request to a Slack webhook
  • Main.hs: Main module, reads the configuration file and then runs the scraper/chatbot at a configurable interval

Libraries

The implementation uses the following libraries:

  • http-client for downloading a web page and sending a POST
  • tagsoup for parsing the web page and getting out the links
  • network-uri to deal with relative/absolute URIs
  • configurator to read the configuration file
