# Citer

Simple CLI that turns an arXiv ID/URL or DOI/URL into a single-line APA citation.

## Setup

```bash
pip install -e .
```

## Usage

```bash
# arXiv IDs or URLs
citer arxiv 2106.01342
citer arxiv https://arxiv.org/abs/2106.01342

# DOIs or DOI URLs
citer doi 10.1038/nphys1170
citer doi https://doi.org/10.1038/nphys1170
```

Errors are printed with a clear message if an ID cannot be parsed or a lookup fails.

## Tests

```bash
python -m pytest
```
