## What it is
Pomsky is a modern, portable regular expression language that cross-compiles to standard regexes for engines like PCRE, JavaScript, Python, Java, .NET, Ruby, Rust, and RE2. It ships as a Rust library and CLI, with a VS Code extension and online playground.

## Use cases
- write readable regexes with saner syntax
- compile pomsky expressions to JavaScript regex
- generate regexes compatible with multiple engines
- replace complex regex with variables and ranges
- test regex patterns with built-in tests

## When to choose
- you maintain complex regexes that are hard to read
- you need the same pattern across multiple regex flavors
- you want editor tooling and diagnostics for regex authoring

## When to avoid
- your team only knows plain regex and won't learn a new syntax
- you target a regex engine Pomsky doesn't support
- you need zero build step in your pipeline

## Facets
- artifact type: library
- maturity: active
- function: parser, compiler, developer-tools
- domain: programming-languages, parsers, developer-tools
- platform: rust, cli, cross-platform
- tags: regex-language, transpiler, regular-expressions, vscode-extension, nodejs
