BibTeX layer

Table of ContentsClose


1. 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.

1.1. 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.
  • Optionally install full fledged ebib reference manager

2. 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.

3. Configuration

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

(setq bibtex-completion-bibliography '("~/Papers/references.bib")
      bibtex-completion-library-path "~/Papers/"
      bibtex-completion-notes-path "~/Papers/")

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, ivy-bibtex and biblio package documentations.

3.1. Ebib and biblio

To enable installation of the ebib reference manager set the variable bibtex-enable-ebib-support as shown in the following code block:

(bibtex :variables
        bibtex-enable-ebib-support t
        ebib-preload-bib-files '("path-to-bib-file.bib")
        ebib-file-search-dirs '("/path-to-documents-directory")
        ebib-import-directory "path-to-e.g.-download-directory")

The code block also shows how to set some optional ebib variables.

With the installation of the ebib package, Spacemacs automatically loads the ebib-biblio package that uses the biblio package to provide an easy way of fetching citations from the web into the database (follow the links to the packages additional descriptions and usage instructions).

4. 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 n Open notes
SPC m b Open browser
SPC m i Insert new entry
SPC m s Sort entry
SPC m h Various actions on entry

In addition, org-mode, latex-mode and markdown-mode all have the following key binding added:
