Cucumber Expressions is an alternative to Regular Expressions with a more intuitive syntax.
Full documentation is at https://cucumber.io/docs/cucumber/cucumber-expressions including syntax, usage examples, and an interactive playground.
See ARCHITECTURE.md
The Cucumber Expression syntax is inspired by similar expression syntaxes in other BDD tools, such as Turnip, Behat and Behave.
Big thanks to Jonas Nicklas, Konstantin Kudryashov and Jens Engel for implementing those libraries.
The Tiny-Compiler-Parser tutorial by Yehonathan Sharvit inspired the design of the Cucumber expression parser.
