rgpy 0.1.0

Rust-powered blazing-fast regex search for Python

rgpy

rgpy is a blazing-fast, Rust-powered regular expression search tool for Python.
It brings the speed of ripgrep and regex into your Python environment, ideal for scanning large log files and datasets.

---

🚀 Features

• Super-fast regex matching (powered by Rust)
• Supports both regex and pcre2
• Multithreaded line scanning (via Rayon)
• Easy-to-use Python API

---

📦 Installation

Install via pip using maturin:

pip install maturin
maturin develop  # for local development

You can also install from PyPI once published:

pip install rgpy

---

🧪 Example Usage

from rgpy import search_file

results = search_file(
    pattern="error",
    path="./logs/sample.log",
    engine="regex",         # or "pcre2"
    ignore_case=True
)

for line in results:
    print(line)

⚙️ Arguments

Parameter	Type	Description
pattern	str	Regex pattern to search
path	str	Path to the target file
engine	str	"regex" (default) or "pcre2"
ignore_case	bool	Case-insensitive matching (optional)

---

🛠 Engine Options

• "regex": Rust’s built-in, fast and safe regex engine (no backreferences or lookbehind)
• "pcre2": Perl-compatible regex with full support for lookaround, backreference, etc. (slightly slower)

---

⚡ Performance

rgpy uses Rust + Rayon for multithreaded file processing.
This makes it significantly faster than Python’s built-in re module, especially for large files.
