gaberoo/doitex

Use doi citations in Latex and fetch automatically from CrossRef.

doitex.rb

Script to automatically parse doi citations from LaTeX documents and download the corresponding references from CrossRef.

Usage

Just cite references in your LaTeX document using the format \cite{doi:<doi>}. Then, after running latex, pdflatex, xelatex, etc., run

ruby doitex.rb <aux_file> <bib_file>

Your bib_file will automatically be augmented with the missing references. If you are compiling a LaTeX document called article.tex with a bibliography file references.bib, run

pdflatex article
ruby doitex.rb article.aux references.bib
bibtex article
pdflatex article
pdflatex article

Hopefully in the future I/you/we can incorporate this into a latexmk workflow.

Using a mapping file

You can also specify a key-to-doi mapping file in YAML format:

citekey1: doi1
citekey2: doi2
...

This might be useful if you want to use identifiable citation keys in your latex document, almost like a barebones bibtex file. Then just call doitex with the -m option:

ruby doitex.rb -m <ref_map> <aux_file> <bib_file>

Citations that don't have a DOI

No problem! doitex just adds missing references to an existing bib file, so you can have anything else in there too.

Dependencies

• bibtex-ruby
• serrano

Installation

You need ruby (comes with macOS and generally with Linux). I've tested this on Ruby 2.4.2, but raise issues if you find compatibility problems. Then, just install the dependencies:

gem install bibtex-ruby serrano

CrossRef polite pool

CrossRef has a polite pool. To get into it, either specify your email address on the command line with the -e flag, or set the CROSSREF_EMAIL environmental variable.

Future work (contributions welcome!)

1. Create a proper gem.
2. Figure out how to add doitex to the latexmk workflow.
