What is the difference between Regex syntax in Ruby vs Perl?

Question

In my understanding, when Matz invented Ruby, he pretty much lifted a lot of Perl language constructs and duplicated them. Does this extend to regular expressions as well, or are there any syntactical differences that I should be aware of?

Answer 1

There's an extensive comparison of regex support in many languages at https://www.regular-expressions.info/refbasic.html and its sibling pages. Enter the two languages that you want to compare wrt support of regex capabilities, and see the differences in the table.
