* lisp/oc-csl.el (org-cite-csl-latex-label-separator): Make first line
of the docstring full sentence. Fix double space between sentences.
(org-cite-csl--create-structure-params): re-fill.
(org-cite-csl--no-citelinks-p): Document the function arguments.
* doc/org-manual.org (Exporting): Add cindex entry for both "backend"
and "back-end" for better searchability.
All other changes are trivial.
Note that `org-element-export-snippet-parser' will still use :back-end
property. So will ox.el in INFO channel.
* lisp/oc-csl.el (org-cite-csl--output-format): Use the dedicated
'org-latex' citeproc formatter to export references in LaTeX.
(org-cite-csl-latex-preamble, org-cite-csl--generate-latex-preamble,
org-cite-csl-finalizer): Insert a preamble fragment compatible with
the 'org-latex' citeproc formatter.
(org-cite-csl-latex-label-separator,
org-cite-csl-latex-label-width-per-char): Introduce additional
variables to control bibliography formatting.
* etc/ORG-NEWS: Describe the introduced new options.
* lisp/oc-csl.el: Register the newly added citation styles "title",
"locators and "bibentry" as supported by the "csl" export processor.
(org-cite-csl--create-structure-params): Add support for the creation
of citation structures with the new citation styles.
* lisp/oc-csl.el (org-cite-csl--rendered-bibliographies): New function
to collect all #+print_bibliography keywords with their properties and
call Citeproc to render all sub-bibliographies in one go as required
by the API. Return the formatted bibliographies as values in an alist
in which keys are the #+print_bibliography keyword options as plists.
Cache the return value in the export communication channel.
(org-cite-csl--bibliography-filter): New helper function to convert
plists representing #+print_bibliography options to the alist filter
form expected by Citeproc.
(org-cite-csl--rendered-citations): Call
`org-cite-csl--rendered-bibliographies' before rendering citations to
make sure that the complete sub-bibliography information is added to
the processor and, therefore, citation numbers are correct.
(org-cite-csl--render-bibliography): Instead of directly calling
Citeproc to render the bibliography, call
`org-cite-csl--rendered-bibliographies' and retrieve the formatted
bibliography from its return value based on the options passed as the
`props' argument.
* lisp/oc-csl.el (org-cite-csl--rendered-citations): Collect nocite
style citations in a separate list as required by the citeproc-el
API. Set the output of all nocite citations to the empty string.
(org-cite-csl--nocite-p): New helper predicate for checking whether a
citation is a nocite.
* lisp/oc-csl.el (org-cite-csl--style-file): When file name is
relative, look for it in default directory before expanding it against
`org-cite-csl-styles-dir'.
(org-cite-csl-styles-dir): Document change.
* lisp/oc.el (org-cite-wrap-citation): Mention return value.
* lisp/oc-csl.el (org-cite-csl--create-structure): Use return value
from `org-cite-wrap-citation' instead of using `org-element-lineage'.
* lisp/oc-csl.el (org-cite-csl--create-structure-params): Add support
for bare (b), bare-caps (bc), bare-full (bf), and bare-caps-full (bcf)
author citation styles.
* lisp/oc-csl.el (org-cite-csl--label-regexp): § is not a word start,
so adjust regexp accordingly. Also fix mistake introduced in
c4a357f192.
(org-cite-csl--parse-reference): Ignore any space after locator name.
* lisp/oc-csl.el (org-cite-csl--etc-dir): Adjust docstring to describe
purpose without tying the variable to the repository install scenario.
Since 604bfd9d7 (oc-csl: be more caution about the csl etc location,
2021-07-15), this value hasn't been limited to the repository's
etc/csl/.
* lisp/oc-csl.el (org-cite-csl--etc-dir): Add `data-directory' case,
using it as the fallback. Also, use the more specific
file-directory-p rather than file-exists-p to inspect the candidates.
When using Org from the system installation, the CSL files will be
available in the etc/org/csl/ subdirectory underneath
`data-directory'. (This requires the etc/csl/ files to be synced to
the Emacs repo under etc/org/csl.)
Give the Org repository and package cases precedence because they are
anchored to a specific oc.el location while, for Emacs releases with
Org 9.5 or later, the data-directory files will typically always be
present.
* lisp/oc-csl.el (org-cite-csl--create-structure-params): Introduce this new
function to map the extended list of supported citation styles and variants to
the corresponding citeproc-el citation structure creation parameters.
(org-cite-csl--no-affixes-p, org-cite-csl--capitalize-p,
org-cite-csl--no-author-p): Remove them since their functionality is provided
now by `org-cite-csl--create-structure-params'.
(org-cite-csl--parse-reference): Don't generate `suppress-author' cite
information as that is treated now by citeproc-el as a citation style.
(org-cite-csl--create-structure): Use `org-cite-csl--create-structure-params' to
generate style-dependent citation structure parameters.
* lisp/oc-csl.el (org-cite-csl--processor): Citeproc-el now provides an
itemgetter constructor with all the required functionality and some more, so we
use it to create the itemgetter instead of `org-cite-csl--itemgetter' to avoid
code duplication and make use of the additional features, in particular the
ability to access bibliographies in `org-bibtex' format
(see <https://gewhere.github.io/org-bibtex>).
(org-cite-csl--itemgetter): Is removed since it is no longer used.
* lisp/oc-csl.el (org-cite-csl-finalizer): The hanging LaTeX package
we're using also affects punctuation and makes `,.'"`?!:;' active
characters throughout the entire document. That means a LaTeX snippet
like \(f'(x)\) will now make the document fail to compile.
See <https://tex.stackexchange.com/questions/61732/hanging-package-chokes-on-apostrophes>
for more information. Adding the [notquote] option stops \(f'(x)\) from
being an issue.
In time it could be worth looking into replacing the hanging package
with some use of \parshape.
* lisp/oc-csl.el (org-cite-csl-finalizer): In order for
citeproc-generated references to be treated the same as bib(la)tex
references by hyperref, we need to make use of \hyper@linkstart.
However, this requires \makeatletter and \makeatother, which can only be
used in the preamble. To allow citeproc-el to use \hyper@linkstart, we
add a command definition in the preamble, \citeprocitem.
