A quick and dirty syntax translation / conversion reference guide to ease the transition between Python and Julia. This is not meant as a reference to the language. For that you should read the manual.

Some important differences

• Arrays in Julia are indexed starting from 1.
• In Julia classes (i.e. types) don't own methods. Methods are implementations of generic functions and are invoked in a "static style", i.e. instead of Python's str1.rstrip(), we will have rstrip( str1 ), instead of file1.close(), close( file1 ).

Some important similarities.

This setup allows to trigger an IFTTT event whenever a web page changes. It uses the urlwatch utility and the IFTTT Maker Channel.

Instructions:

• Sign up to IFTTT.
• Connect IFTTT's Maker Channel, and take note of your Maker key.
• Create a new Recipe that takes the Maker Channel as input and outputs wherever you want. I used IF Notifications with the IF Android app, so that I get a notification on my phone whenever the trigger runs. The script passes the updated URL to IFTTT as value1, and my notification contains URL updated: {{Value1}}, so that I know which of the web pages has been updated.
• On the machine that will check the website for changes install urlwatch and python2-requests.
• Echo the URLs to check to ~/.urlwatch/urls.txt, one per line.
• Then, copy over my hooks.py to ~/.urlwatch/libs/hooks.py adding the URLs to the ifttt_urls tuple and substituting YOUR_TRIGGER_NAME and YOUR_MAKER_KEY.
