Jekyll-Scholar
==============

Jekyll-Scholar is for all the academic bloggers out there. It is a set of
extensions to [Jekyll](http://jekyllrb.com/), 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.

Install and setup a new [Jekyll](http://jekyllrb.com/) directory (see the
[Jekyll-Wiki](https://github.com/mojombo/jekyll/wiki/Usage) 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'

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](https://github.com/citation-style-language/styles)).

The `use_raw_bibtex_entry` option will disable parsing of Liquid tags that 
are embedded in the Bibtex fields. This option provides a way to circumvent 
the problem that the double braces functionality of BibTex is accidentally 
parsed by Liquid, while it was intended to keep the exact capitalization style.

### 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:

If you are using other converters to generate your site, don't worry, you can
Sylvester Keil's avatar
Sylvester Keil committed
118 119 120 121 122 123 124 125 126 127
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 --file books %}` and

149 150 151
Finally, the bibliography tag supports an optional filter parameter. This
filter takes precedence over the global filter defined in your configuration.

Bjoern Rueffer (Air)'s avatar

152
    {% bibliography --query @*[year=2013] %}
Sylvester Keil's avatar
Sylvester Keil committed
153 154 155 156 157

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:

Sylvester Keil's avatar
Sylvester Keil committed
158
    {% bibliography -f secondary -q @*[year=2013] %}
Sylvester Keil's avatar
Sylvester Keil committed
159 160 161 162 163 164 165 166

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](https://github.com/inukshuk/bibtex-ruby)
documentation.

167 168 169 170 171 172 173 174
If you need to limit the number of entries in your bibliography, you can
use the `--max` option:

    {% bibliography --max 5 %}

This would generate a bibliography containing only the first 5 entries
of your bibliography (after query filters and sort options have been applied).

175 176 177 178 179 180 181
### Bibliography Template

Your bibliography is always rendered as an ordered list. Additionally,
each reference is wrapped in an HTML tag (`span` by default but you can
change this using the `reference_tagname` setting) with the cite key
as id. The reference string itself is governed by the rules in your
CSL style but you can also customize the main template a little bit.
182 183
By default, the template is `{{reference}}` – this renders only the
reference tag. The template uses Liquid to render and, in
184
addition to the reference, exposes the cite-key (as `key`), the
185 186
entry's `type`, the `index` in the bibliography, and the link to
file repository as `link`. Thus, you could
187 188 189
customize the template in your configuration as follows:

    scholar:
190
      bibliography_template: <abbr>[{{key}}]</abbr>{{reference}}
191 192 193

This would be processed into something like:

194
    <li><abbr>[ruby]</abbr><span id="ruby">Matsumoto, Y. (2008). <i>The Ruby Programming Language</i>. O&#8217;Reilly Media.</span></li>
195

196 197 198 199 200 201 202 203 204 205 206 207 208 209 210 211 212 213 214
If you have more complex requirements, it quickly becomes tedious to
have the template inside the configuration; for this reason, you can
also put the bibliography template into your layouts directory. Jekyll-Scholar
will load this template if the option set in your configuration matches
an existing layout (without the file extension). That is to say, if you set:

    scholar:
      bibliography_template: bib

And there is a file `_layouts/bib.html` (or with another extension) the
contents of this file will be used as the template. Please note that it is
important for this file to contain the YAML front matter! For example, this
would be a more complex template file:

    ---
    ---
    {{ reference }}

    {% if entry.abstract %}

Sylvester Keil's avatar

219

220 221 222
You can also override the default bibliography template, by passing the
`--template` or `-T` option parameter to the bibliography tag.

257 258 259 260
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:

Bjoern Rueffer (Air)'s avatar
Bjoern Rueffer (Air) committed
261
    {% bibliography --cited %}
262

Sylvester Keil's avatar
Sylvester Keil committed
263 264 265 266 267 268
By default, the `--cited` option will still sort your bibliography if you set
the sort option. Especially for styles using citation numbers, this is usually
not the desired behaviour. In such cases you can use `--cited_in_order` instead
of `--cited` and your bibliography will contain all cited items in the order
they were cited on the page.

Sylvester Keil's avatar

269 270 271 272 273
For longer quotes, Jekyll-Scholar provides a `quote` tag:

    {% quote derrida:purveyor %}
    Lorem ipsum dolor sit amet, consectetur adipisicing elit,
    sed do eiusmod tempor.
Sylvester Keil's avatar

275 276 277 278 279 280 281 282 283 284 285 286 287 288
    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>

289 290 291 292 293 294
#### Multiple citation

You can cite multiple items in a single citation by referencing all ids
of the items you wish to quote separated by spaces. For example,
`{% cite ruby microscope %}` would produce a cite tag like:

Sylvester Keil's avatar
Sylvester Keil committed
295
    <a href="#ruby">(Flanagan &amp; Matsumoto 2008; Shaughnessy 2013)</a>
296

Sylvester Keil's avatar
Sylvester Keil committed
297 298 299 300 301 302 303 304
#### Suppressing author names

Sometimes you want to suppress author names in a citation, because the
name has already been mentioned in your text; for such cases Jekyll-Scholar
provides the `--suppress_author` option (short form: `-A`):
`...as Matz explains {% cite ruby -A -l 42 %}` would produce something
like: `...as Matz explains (2008, p. 42)`.

305 306 307 308
#### Page numbers and locators

If you would like to add page numbers to your citation, you can use the
`-l` or `--locator` option. For example, `{% cite ruby -l 23-5 %}` would
Sylvester Keil's avatar
Sylvester Keil committed
309
produce a citation like `(Matsumoto, 2008, pp. 23-5)`.
310 311 312 313

When quoting multiple items (see above) you can add multiple locators after
the list of ids. For example, `{% cite ruby microscope -l 2 -l 24 & 32 %}`.

314 315 316 317 318 319 320 321 322 323 324 325 326
#### 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
Sylvester Keil's avatar
Sylvester Keil committed
327 328
"Flanagan, D., & Matsumoto, Y. (2008). *The Ruby Programming Language.*.
O'Reilly Media" (the exact result depends on your formatting style).
329

Sylvester Keil's avatar
Sylvester Keil committed
330 331 332
The `reference` tag accepts the same --file/-f parameter as the bibliography
tag. This can be handy if you want to use a special BibTeX file as input for
a specific page. As an example, the tag
333

Bjoern Rueffer (Air)'s avatar
Bjoern Rueffer (Air) committed
334
    {% reference ruby --file /home/foo/bar.bib %}
335 336

will attempt to read the key `ruby` from file `/home/foo/bar.bib`. It will not

#### Multiple bibliographies within one document (like [multibib.sty](http://www.ctan.org/pkg/multibib))
Bjoern Rueffer (Air)'s avatar
Bjoern Rueffer (Air) committed
340 341

When you have multiple `{% bibliography %}` sections in one file,
Sylvester Keil's avatar
Sylvester Keil committed
342
Jekyll-Scholar will generate several lists containing the same
Bjoern Rueffer (Air)'s avatar
Bjoern Rueffer (Air) committed
343 344 345
publications that have the same `id` attributes. As a result, when you
cite a reference the link to an `id` attribute cannot be resolved
uniquely. Your browser will always take you take you to the first
Sylvester Keil's avatar
Sylvester Keil committed
346
occurrence of the `id`. Moreover, valid HTML requires unique `id`
Bjoern Rueffer (Air)'s avatar
Bjoern Rueffer (Air) committed
347 348 349 350 351
attributes. This scenario may happen, for example, if you cite the
same reference in different blog posts, and all of these posts are
shown in one html document.

As a solution, Jekyll-Scholar provides the `--prefix` tag. In your
Sylvester Keil's avatar

352
first post you might cite as

### File Repositories

File repository support was added to Jekyll-Scholar starting at version
Sylvester Keil's avatar
Sylvester Keil committed
397
2.0. Currently, if you have a folder in your site that contains PDF or
Sylvester Keil's avatar
Sylvester Keil committed
398 399 400 401
Postscript files of your papers, you can use the configuration option
`repository` to indicate this directory. When generating bibliographies,
Jekyll-Scholar will look in that folder to see if it contains a filename
matching each entry's BibTeX key: if it does, the path to that file
402 403 404 405 406 407 408 409
will be exposed to the bibliography template as the `link` property.

Since version 4.1.0 repositories are not limited to PDF and PS files.
These files are mapped to the `links` property in your bibliography
template. Here is an example of template that utilizes this feature
to link to supporting material in a ZIP archive:

    {{ reference }} [<a href="{{links.zip}}">Supporting Materials</a>]

### Detail Pages

If your layouts directory contains a layout file for bibliography details
414
(the `details_layout` configuration options), Jekyll-Scholar will generate

Sylvester Keil committed
415 416 417 418 419 420 421 422 423 424 425 426 427 428 429 430 431 432 433 434
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:

    ---

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).

### 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
467 468
    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 2.3.0 or

later versions. You can also overwrite the configuration's query parameter
in each bibliography tag individually as described above.
