BibTeX layer

Description

BibTeX and BibLaTeX files are a common way to manage bibliographies. The format was original designed to work with LaTeX files and subsequently has been adopted by other markup formats such as MarkDown and Org mode.

This layer adds support to manipulate BibTeX and BibLaTeX files in Spacemacs.

Features:

Syntax highlighting for BibTeX and BibLaTeX files.
Utilities for automatically adding entries from different data sources.
Support for inserting citations in various other modes.

Install

To use this configuration layer, add it to your ~/.spacemacs. You will need to add bibtex to the existing dotspacemacs-configuration-layers list in this file.

Configuration

This layer also supports having a global BibTeX file. For a basic configuration, add this to your ~/.spacemacs inside dotspacemacs/user-config:

  (setq org-ref-default-bibliography '("~/Papers/references.bib")
        org-ref-pdf-directory "~/Papers/"
        org-ref-bibliography-notes "~/Papers/notes.org")

Certain modes, such as latex-mode with AucTeX, will automatically lookup references in a document if any of the recognized bibliography commands are used. Other modes may have a similar feature, or one could always set file-local variables (through SPC f v f).

You can also customize which program is used to display the PDFs. For example, to use Zathura:

  (setq org-ref-open-pdf-function
    (lambda (fpath)
      (start-process "zathura" "*helm-bibtex-zathura*" "/usr/bin/zathura" fpath)))

More configuration options are available and are detailed in the org-ref, helm-bibtex and ivy-bibtex package documentations.

Key bindings

In a Bib(La)TeX file, the following key bindings are added:

Key binding	Description
`SPC m j` / `g j` / `C-j`	Next entry
`SPC m k` / `g k` / `C-k`	Previous entry
`SPC m p`	Open PDF

`SPC m l A`	Lookup and add arXiv paper (download PDF)
`SPC m l d`	Lookup and add paper by DOI
`SPC m l i`	Lookup and add book by ISBN
