Clean Phone numbers with RegEx in AutoHotkey

In this video I show how to use a function calling a RegEx (a Regular Expression ) to clean phone numbers.

Using a Regular Expression (RegEx) to Find a URL and not an email address

A subscriber reached out to me (after trying for a few hours) for some help on creating a Regular Expression to pull-out URLs from text. Specifically not including email addresses. Since he gave it a solid try I wanted to help him out. I did a google search and found this post which had the RegEx pattern for finding a URL and not an email address. I then took the pattern and put it on Regular Expressions 101 to make sure it would work in AutoHotkey. After that I adapted it to AutoHotkey code (see below) using RegExMatch.

RegExMatch example with AutoHotkey

A subscriber of my YouTube channel had an issue with using RegExMatch. I decided it was better to walk through the process in a video than to just provide the code. 🙂 As mentioned in the video I highly recommend Jack Dunning’s Regular Expressions AutoHotkey book. Continue reading

Example Webservice / API call- Yelp and working through oAuth2

In our API webinar we discussed how oAuth2 works however there is no better way to explain it than to actually work through an example! In the below video & code I demonstrate how to access Yelp to perform the “handshake” with oAuth1 and receive the oAuth2 authentication. I also demonstrate using a named Regular Expression to isolate the returned token.
