Ogex

A custom regex engine with unified syntax for named groups and backreferences.

Overview

Ogex introduces a cleaner, more intuitive syntax for named capturing groups and backreferences:

• Named groups: (name:pattern) instead of (?<name>pattern)
• Backreferences: \g{name} or \g{1} instead of \k<name> or \1
• Works identically in patterns and replacement strings

The engine is written in Rust for performance and provides bindings for multiple languages.

Important

This project is going to soon be moved to a self-hosted Forgejo instance Currently it will act as a push-mirror, and in the future, github will be the push-mirror The repository is already available at: https://hangar.nixthedev.ru/NiXTheDev/Ogex

Crates

Crate	Description
ogex	Core regex library (Rust)
ogex-cli	CLI tool
ogex-python	Python bindings

Quick Start

Rust

See ogex/README.md

JavaScript/WASM

import { Regex } from '@ogex/ogex';

const regex = new Regex('(name:hello)');
const match = regex.find('hello world');
console.log(match.text);  // "hello"

Python

import ogex

regex = ogex.Regex(r"(name:\w+) is \g{name}")
match = regex.search("John is John")
print(match.named_group("name"))  # "John"

CLI

# Test a pattern
ogex test "(name:hello)" "hello world"

# Convert syntax
ogex convert "(name:abc)"
# Output: (?<name>abc)
