# Arxiv::References

Welcome to your new gem! In this directory, you'll find the files you need to be able to package up your Ruby library into a gem. Put your Ruby code in the file `lib/arxiv/references`. To experiment with that code, run `bin/console` for an interactive prompt.

## Dependencies

- k2pdfopt (http://www.willus.com/k2pdfopt/)

## Installation

### Install arxiv-references

```ruby
gem 'arxiv-references'
```

And then execute:

    $ bundle

Or install it yourself as:

    $ gem install arxiv-references

## Usage

### fetch paper information from arxiv url
`arxiv-ref url <arxivurl>`

### fetch paper information from arxiv ID
`arxiv-ref id <arxivid>`

### fetch paper citation list from PDF URL
`arxiv-ref pdfurl <pdfurl>`

### Options
--work_dir : [default: /tmp] working directory to convert multi column pdf to one column
--use_dir  : [default: true] create working directory or not


## Development

After checking out the repo, run `bin/setup` to install dependencies. Then, run `rake spec` to run the tests. You can also run `bin/console` for an interactive prompt that will allow you to experiment.

To install this gem onto your local machine, run `bundle exec rake install`. To release a new version, update the version number in `version.rb`, and then run `bundle exec rake release`, which will create a git tag for the version, push git commits and tags, and push the `.gem` file to [rubygems.org](https://rubygems.org).
