Usually this pattern is then used by string searching algorithms for "find" or "find and replace" operations on strings.) <https://en.wikipedia.org/wiki/Regular_expression> Ruby programming language documentation, Regexp class page, viewed February 7, 2018: (Regular expressions (regexps) are patterns which describe the contents of a string. They're used for testing whether a string contains a given pattern, or extracting the portions that match.) <http://ruby-doc.org/core-2.5.0/Regexp.html> Perl 6 Documentation, Regexes, viewed February 7, 2018: (Regular expressions, regexes for short, are a sequence of characters that describe a pattern of text. Pattern matching is the process of matching those patterns to actual text.) <https://docs.perl6.org/language/regexes> TechTarget, Oct. 15, 2018 (Regular expression (regex): A regular expression (sometimes abbreviated to "regex") is a way for a computer user or programmer to express how a computer program should look for a specified pattern in text and then what the program is to do when each pattern match is found. For example, a regular expression could tell a program to search for all text lines that contain the word "Windows 95" and then to print out each line in which a match is found or substitute another text sequence (for example, just "Windows") where any match occurs) |
