What is regex?

Regular expressions, or regex, are a powerful tool for pattern matching and text manipulation. Regex is a sequence of characters that define a search pattern, which can be used to find, replace, or validate text. Regex originated in the 1950s and gained popularity in Unix tools like sed and grep. Today, regex is supported by most programming languages and is widely used for tasks such as data validation, web scraping, and log parsing.

FAQ about regex

What is the difference between regex and wildcard characters?
While both regex and wildcard characters are used for pattern matching, regex is much more powerful and flexible. Wildcard characters, such as * and ?, provide basic pattern matching capabilities, while regex supports a wide range of special characters and constructs, enabling more complex and specific patterns.
Is regex case-sensitive?
By default, regex is case-sensitive. However, most regex engines provide options or flags to enable case-insensitive matching.
Can regex be used to match patterns across multiple lines?
Yes, regex can match patterns across multiple lines. Most regex engines provide options or flags to enable multiline matching, allowing the ^ and $ anchors to match the start and end of each line, respectively.
How can I learn regex?
There are many resources available to learn regex, including online tutorials, books, and interactive tools. Some popular resources include RegexOne, Regular-Expressions.info, and the 'Mastering Regular Expressions' book by Jeffrey Friedl.
Are regex patterns portable across programming languages?
While regex syntax is largely standardized, there can be slight variations between programming languages or regex engines. It's important to consult the documentation for the specific language or tool you are using to ensure compatibility.
What are some common use cases for regex?
Some common use cases for regex include data validation, web scraping, log parsing, and text manipulation. Regex is particularly useful for tasks that involve identifying and extracting specific patterns from text.
