wtf is melody?

Melody is a tool that lets you write pattern-matching rules in a readable, sentence-like format instead of using regular expressions directly. Regular expressions (regex) are notoriously cryptic, strings like /\w+\s1\d{2}/ are hard to write, harder to read, and nearly impossible to revisit weeks later. Melody solves this by giving you a cleaner syntax that compiles down to the same regex you'd normally hand-write. You write Melody code using plain keywords and symbols. For example, some of <word> means "one or more word characters" (which compiles to \w+), and 2 of <digit> means "exactly two digits" (\d{2}). You can name capture groups with readable syntax like capture major { ... }, which turns into the regex equivalent (?<major>...). Literals like "batman" get automatically escaped, so you don't have to worry about special characters. The result is code that reads almost like English but produces the same compact regex output machines expect. This is aimed at anyone who writes regex but finds it painful, developers, data analysts, QA engineers, or anyone validating and extracting text. If you've ever needed to match a semantic version string, find indented code blocks, or parse hashtags, Melody lets you express those patterns in a way a teammate can actually understand without consulting a regex cheat sheet. You can try it in a browser-based playground before installing anything. The project is written in Rust and currently targets the JavaScript flavor of regex. It's explicitly early and unstable, with a detailed feature matrix showing what works versus what's still planned, things like nested groups and lookbehind aren't implemented yet. There's a VSCode extension for syntax highlighting, and the compiler is available as a Rust crate, a command-line tool, and a WASM binding for browser use. The file extension for Melody source files is .mdy.
