GitHub - pemistahl/grex: A command-line tool and Rust library with Python bindings for generating regular expressions from user-provided test cases
grex is a library as well as a command-line utility that is meant to simplify the often complicated and tedious task of creating regular expressions. It does so by automatically generating a single regular expression from user-provided test cases. The resulting expression is guaranteed to match the test cases which it was generated from. This project has started as a Rust port of the JavaScript to

ES2020: `String.prototype.matchAll`
The proposal “String.prototype.matchAll†by Jordan Harband is currently at stage 3. This blog post explains how it works. Before we look at the proposal, let’s review the status quo. Getting all matches for a regular expression  # At the moment, there are several ways in which you can get all matches for a given regular expression. RegExp.prototype.exec() with /g  # If a regular expression has the
Building a RegExp machine. Part 1: Regular grammars
In this series of articles we’re going to study a theory and implementation behind the formalism of regular expressions, — the technique used for text processing, implementation of tokenizers, etc. Audience: experienced programmers, professionals. You can also see more details, and enroll to full course. Note: this is not a series on “how to use regexpâ€, but rather on “how to implement regexpâ€. Yo
Upcoming regular expression features  | Blog  | Chrome for Developers
ES2015 introduced many new features to the JavaScript language, including significant improvements to the regular expression syntax with the Unicode (/u) and sticky (/y) flags. But development has not stopped since then. In tight collaboration with other members at TC39 (the ECMAScript standards body), the V8 team has proposed and co-designed several new features to make regular expressions even m
