Where to get this filter

This filter is included in the official Pandoc Lua filter repository (https://github.com/pandoc/lua-filters).

pandoc-doi2cite

This pandoc lua filiter helps users to insert references in a document with using DOI(Digital Object Identifier) tags. With this filter, users do not need to make bibtex file by themselves. Instead, the filter automatically generate .bib file from the DOI tags, and convert the DOI tags into citation keys available by --citeproc.

What the filter do are as follows:

1. Search citations with DOI tags in the document
2. Search corresponding bibtex data from __from_DOI.bib file
3. If not found, get bibtex data of the DOI from http://api.crossref.org
4. Add reference data to __from_DOI.bib file
5. Check duplications of reference keys
6. Replace DOI tags to the correspoinding citation keys

Prerequisites

• Pandoc version 2.0 or newer
• This filter does not need any external dependencies
• This filter should be executed before pandoc-crossref or --citeproc

DOI tags

Following DOI tags can be used:

• @https://doi.org/
• @doi.org/
• @DOI:
• @doi:

The first one (@https://doi.org/) may be the most useful because it is same as the accessible URL.

YAML header

The file name of the auto-generated bibliography file MUST be __from_DOI.bib, but the place of the file can be changed (e.g. './refs/__from_DOI.bib' or 'refs\\__from_DOI.bib' for Windows). Yo u can designate the filepath in the document yaml header. The yaml key is bibliography, which is also used by --citeproc.

Example

example1.md:

---
bibliography:
  - 'my_refs.bib'
  - '__from_DOI.bib'
---
