It would be really good to have support for regular expressions.
This could be surfaced in the UI ideally in both conditions and actions.
A conditional regex would just test whether a string matched against a regex.
An action regex would expose capture groups.
This is a great suggestion - we are trying to identify a way to safely run regex in Flow.
Great news, thanks for the update @Stephen. We will welcome regex with open arms.
@Stephen, any update?
+1 I think this calls for a lightbulb joke.
Q: How many engineers does it take to type in a Regex?
Here is to confirm that we are also very much interested in this capability. Any update at this point?
