Piecewise - Regular Expressions

Analyze and act on text with the free Regular Expressions DLC pack!

Regular expressions are a set of rules that tell computers how to analyze text for patterns. You might use a regular expression to determine whether text meets a certain set of criteria, and potentially act on it by replacing and capturing matches. The Piecewise Regular Expressions add-on adds 4 blocks that allow you to utilize regular expressions.

With the Piecewise Regular Expressions add-on, you can use regular expressions to determine whether, for example:

• a file has a certain extension
  
• a message contains a URL
  
• a message contains characters that do not appear in a particular script (i.e. Latin)
  
• arbitrary text starts with or ends with a particular pattern

Note that you must be running at least Piecewise 23.01.0 ("Fireworks Beneath My Shoes") to use this addon. You can view your version of Piecewise from the Piecewise menu -> About Piecewise...
