Jekyll-Scholar
Jekyll-Scholar is for all the academic bloggers out there. It is a set of extensions to Jekyll, the awesome, blog aware, static site generator; it formats your bibliographies and reading lists for the web and gives your blog posts citation super-powers.
For additional features you may also want to take a look at jekyll-scholar-extras.
Installation
$ [sudo] gem install jekyll-scholar
Usage
Install and setup a new Jekyll directory (see the
Jekyll-Wiki for detailed
instructions). To enable the Jekyll-Scholar add the following statement
to a file in your plugin directory (e.g., to _plugins/ext.rb):
require 'jekyll/scholar'
In your configuration you can now adjust the Jekyll-Scholar settings. The default configuration is as follows:
scholar:
style: apa
locale: en
sort_by: none
order: ascending
source: ./_bibliography
bibliography: references.bib
details_dir: bibliography
details_layout: bibtex.html
details_link: Details
query: "@*"
You can use any style that ships with CiteProc-Ruby by name (e.g., apa, mla, chicago-fullnote-bibliography), or else you can add a link to any CSL style (e.g., you could link to any of the styles available at the official CSL style repository).
The locale settings defines what language to use when formatting
your references (this typically applies to localized terms, e.g., 'Eds.' for
editors in English).
The source option indicates where your bibliographies are stored;
bibliography is the name of your default bibliography.
Bibliographies
Once you have loaded Jekyll-Scholar, all files with the extension .bib or
.bibtex will be converted when you run Jekyll (don't forget to add a YAML
header to the files); the file can contain regular HTML or Markdown and
BibTeX entries; the latter will be formatted by Jekyll-Scholar according to
the citation style and language defined in your configuration file.
For example, if you had a file bibliography.bib in your root directory:
---
---
References
==========
@book{ruby,
title = {The Ruby Programming Language},
author = {Flanagan, David and Matsumoto, Yukihiro},
year = {2008},
publisher = {O'Reilly Media}
}
It would be converted to bibliography.html with the following content:
<h1 id='references'>References</h1>
<p>Flanagan, D., & Matsumoto, Y. (2008). <i>The Ruby Programming Language</i>. O’Reilly Media.</p>
This makes it very easy for you to add your bibliography to your Jekyll-powered blog or website.
If your using other converters to generate your site, don't worry, you can
still generate bibliographies using the bibliography tag. In your site
or blog post, simply call:
{% bibliography %}
This will generate your default bibliography; if you use multiple, you can also pass in a name to tell Jekyll-Scholar which bibliography it should render.
Let's say you have two bibliographies stored in _bibliography/books.bib and
_bibliography/papers.bib; you can include the bibliographies on your site
by respectively calling {% bibliography books %} and
{% bibliography papers %}. For example, you could have a file references.md
with several reference lists:
---
title: My References
---
{{ page.title }}
================
The default Bibliography
------------------------
{% bibliography %}
Secondary References
--------------------
{% bibliography secondary %}
Finally, the bibliography tag supports an optional filter parameter. This filter takes precedence over the global filter defined in your configuration.
{% bibliography filter: @*[year=2013] %}
The example above would print a bibliography of all entires published in the year 2013. Of course you can also combine the file and filter parameters like this:
{% bibliography secondary filter: @*[year=2013] %}
This would print the publications from 2013 of the bibliography at
_bibliography/secondary.bib.
For more details about filters, see the corresponding section below or consult the BibTeX-Ruby documentation.
Citations
If you want to reference books or papers from your bibliography in your blog
posts, Jekyll-Scholar can help you, too. Simply use the cite tag with
the appropriate key of the item you want to cite and Jekyll-Scholar will
create a formatted citation reference for you. For a quick example, take
following blog post:
---
layout: default
title: A Blogging Scholar
---
{{ page.title }}
================
Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor
incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam, quis
nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat.
Duis 'aute irure dolor in reprehenderit in voluptate' {% cite derrida:purveyor %}
velit esse cillum dolore eu fugiat nulla pariatur. Excepteur sint occaecat
cupidatat non proident, 'sunt in culpa qui officia deserunt mollit anim id est
laborum' {% cite rabinowitz %}.
Duis 'aute irure dolor in reprehenderit in voluptate' {% cite breton:surrealism %}
velit esse cillum dolore eu fugiat nulla pariatur. Excepteur sint occaecat
cupidatat non proident, 'sunt in culpa qui officia deserunt mollit anim id est
laborum' {% cite rainey %}.
References
----------
{% bibliography %}
Note that this will print your entire bibliography in the Reference section.
If you would like to include only those entries you cited on the page, pass
the cited option to the bibliography tag:
{% bibliography cited %}
For longer quotes, Jekyll-Scholar provides a quote tag:
{% quote derrida:purveyor %}
Lorem ipsum dolor sit amet, consectetur adipisicing elit,
sed do eiusmod tempor.
Lorem ipsum dolor sit amet, consectetur adipisicing.
{% endquote %}
For example, this could be rendered as:
<blockquote>
<p>Lorem ipsum dolor sit amet, consectetur adipisicing elit,<br/>
sed do eiusmod tempor.</p>
<p>Lorem ipsum dolor sit amet, consectetur adipisicing.</p>
<cite>
<a href="#derrida:purveyor">(Derrida, 1975)</a>
</cite>
</blockquote>
Displaying formatted references
If you want to display the full formatted reference entry, you can use the
reference tag. For example, given the following Bibtex entry,
@book{ruby,
title = {The Ruby Programming Language},
author = {Flanagan, David and Matsumoto, Yukihiro},
year = {2008},
publisher = {O'Reilly Media}
}
using {% reference ruby %} anywhere in your page, it will print
"Flanagan, D., & Matsumoto, Y. (2008). The Ruby Programming Language..
O'Reilly Media" (the exact result depends on your formatting style).
The reference tag accepts a second optional argument that specifies the
absolute path of the BibTeX file to use as input. Using it, you can override
the file from which the bib entries are read. This can be handy if you
want to use a special BibTeX file as input for a specific page. As an example,
the tag
{% reference ruby, /home/foo/bar.bib %}
will attempt to read the key ruby from file /home/foo/bar.bib. It will not
fallback to the default BibTeX file.
Detail Pages
If your layouts directory contains a layout file for bibliography details (the 'details_layout' configuration options), Jekyll-Scholar will generate a details page for each entry in you main bibliography. That is to say, if your bibliography contains the following entry:
@book{ruby,
title = {The Ruby Programming Language},
author = {Flanagan, David and Matsumoto, Yukihiro},
year = {2008},
publisher = {O'Reilly Media}
}
Then a page 'bibliography/ruby.html' will be generated according to your details page layout. In the layout file, you have access to all fields of your BibTeX entry. Here is an example of a details page layout:
---
---
<html>
<head></head>
<body>
<h1>{{ page.entry.title }}</h1>
<h2>{{ page.entry.author }}</h2>
<p>{{ page.entry.abstract }}</p>
</body>
</html>
When Jekyll-Scholar generates detail pages, it also adds links to each entry's detail page to the generated bibliography. You can alter the name of the link via the 'details_link' configuration option.
Jekyll-Scholar also provides a Liquid tag for conveniently adding links
to individual detail pages. For example, if you would like to add a simple
link to one of the items in your bibliography on a page or in a blog post
you can use the cite_details tag to generate the link. For this to work,
you need to pass the BibTeX key of the element you want to reference to
the tag and, optionally, provide a text for the link (the default text
can be set via the 'details_link' configuration option).
Duis 'aute irure dolor in reprehenderit in voluptate' velit esse cillum
dolore eu fugiat nulla pariatur. Excepteur sint occaecat cupidatat non
proident {% cite_details key, Click Here For More Details %}.
Bibliography Filters
By default, Jekyll-Scholar includes all entries in you main BibTeX file when generating bibliographies. If you want to include only those entries matching certain criteria, you can do so by adjusting the 'query' configuration option. For example:
query: "@book" #=> includes only books
query: "@article[year>=2003]" #=> includes only articles published 2003 or later
query: "@*[url]" #=> includes all entries with a url field
query: "@*[status!=review]" #=> includes all entries whose status field is not set to 'review'
query: "@book[year <= 1900 && author ^= Poe]" #=> Books published before 1900 where the author matches /Poe/
Please note that some of these queries require bibtex-ruby 2.0.7 or later versions. You can also overwrite the configuration's query parameter in each bibliography tag individually as described above.
