PostAgents

Bookmark with GimmeBar

As of 2015-02-20 you can replicate adding a page to Gimme Bar without API access by extracting the relevant cookies/fields from a POST request to https://gimmebar.com/bookmarklet/capture. Load a page you're going to bookmark, fire up a network inspector (e.g. Chromium's Developer Tools - Network tab) and use the Extension/Bookmarklet to add the page to your gimmebar. You should extract cookies: gimmebookmarklet and gimmebar.session, and the post field _csrf. With these you can setup a PostAgent:

{
  "post_url": "https://gimmebar.com/bookmarklet/capture",
  "expected_receive_period_in_days": "1",
  "content_type": "form",
  "method": "post",
  "payload": {
    "source": "{{url}}",
    "url": "{{url}}",
    "title": "{{title}}",
    "private": "0",
    "use_prev": "0",
    "_csrf": "REPLACE_ME"
  },
  "headers": {
    "Cookie": "gimmebookmarklet=REPLACE_ME; gimmebar.session=REPLACE_ME"
  },
  "disable_ssl_verification": "true"
}

Wunderlist Agent

Make sure you set up a Wunderlist OAuth Application. Then authenticate against Wunderlist in the Services section of your huginn installation.

XKCD to Wunderlist

In your huginn instance go to Services -> Import Scenario and enter https://dl.dropboxusercontent.com/u/62784372/xkcd-to-wunderlist.json as the public scenario URL. Select the Wunderlist account you want to use, and confirm that you want to import that scenario.

Important: After the import you need to edit the XKCD Publisher (Wunderlist Agent). Click on Actions -> Edit agent and select the List you want to use to store new XKCD Comics.

##Event Formatting Agent - Replace emails in event hash with URL

Easy way to filter and replace content in event using regexp_replace

    "message": "{{ content | regex_replace: '(\\S+)@(\\S+).(\\S+)', '{{url}} ' }}"
  }
}

Daily updates from Github commits

Get an email digest of commits. Ugly formatting, so please feel free to improve!

Daily Update of Huginn Commits on Github

Else-If loops & formatting strings as numbers

Numbers are extracted as strings often and cause issues with comparators. One can either use multiply:1 to cast them as integers or otherwise use string length depending on the goal. Combined with if/elsif/else here:

 {% if total.size >= 7 %}${{total | divided_by:1000000 }}M{% elsif total.size >=6 %}${{round_raised | divided_by:1000}}K{% else %}below $100,000{% endif %}

Get today's date in Liquid Formatting

This is useful for the subject line in Daily EmailDigestAgent agents

{% assign current_date = 'now' | date: '%s' %} {{current_date | date: \"%a, %b %d, %Y\" }}

Amazon Pricewatch

Get an email whenever something drops below a certain price on Amazon
