Ruby Regex Interpolation at Benjamin Uchida blog

Ruby Regex Interpolation. Ruby regular expressions (ruby regex for short) help you find specific patterns inside strings, with the intent of extracting data for further processing. What if you want to merge a variable, or even numbers into another string? Probably regexp.escape(foo) would be a starting point, but is there a good reason you can't use the more conventional expression. R = /(?\w+)/ /(?\w+)\s*=\s*#{r}/ =~ 'x = y' p foo #.</p> A regexp interpolation, #{}, also disables the assignment: Two common use cases for regular expressions include validation & parsing. How can you combine two or more strings together? A regexp may contain interpolated strings; Regular expressions are sort of a swiss army knife for finding things in strings (text), extracting parts of them, or mass replacing certain bits. You can interpolate variables into your regex using the #{} syntax, making your patterns dynamic. Foo = 'bar' /#{foo}/ # => /bar/ =~ and regexp#match. Use the concat method & string interpolation!
