pyrxiv 0.2.0

A Python package for retrieving arXiv papers and filter them out with respect to some specific regex pattern.

pyrxiv

pyrxiv is a Python package for retrieving arXiv papers, storing their metadata in pydantic-like classes, and optionally filtering some of them out based on the specific content of the papers (matching a regex pattern).

While originally developed for the Strongly Correlated Electron Systems community in Condensed Matter Physics (cond-mat.str-el), it's designed to be flexible and applicable to any arXiv category.

Install the core package:

pip install pyrxiv

Objective

pyrxiv main objective is to provide an easy command line interface (CLI) to search and download arXiv papers which contain a specific content string matched against a regex pattern. You can use the CLI and print the options after installing the package using:

pyrxiv --help

or directly:

pyrxiv search_and_download --help

For example:

pyrxiv search_and_download --category cond-mat.str-el --regex-pattern "DMFT|Hubbard" --n-papers 5

Development

To contribute to pyrxiv or run it locally, follow these steps:

Clone the Repository

git clone https://github.com/JosePizarro3/pyrxiv.git
cd pyrxiv

Set Up a Virtual Environment

We recommend Python ≥ 3.10:

python3 -m venv .venv
source .venv/bin/activate

Install Dependencies

Use uv (faster than pip) to install the package in editable mode with dev extras:

pip install --upgrade pip
pip install uv
uv pip install -e .[dev]

Run tests

Use pytest with verbosity to run all tests:

python -m pytest -sv tests

To check code coverage:

python -m pytest --cov=pyrxiv tests

Code formatting and linting

We use Ruff for formatting and linting (configured via pyproject.toml).

Check linting issues:

ruff check .

Auto-format code:

ruff format .

Manually fix anything Ruff cannot handle automatically.
