* 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.

|
||
;;; Commentary:
|
||
|
||
;; This library registers the `csl' citation processor, which provides
|
||
;; the "export" capability for citations.
|
||
|
||
;; The processor relies on the external Citeproc Emacs library, which must be
|
||
;; available prior to loading this library.
|
||
|
||
;; By default, citations are rendered in Chicago author-date CSL style. You can
|
||
;; use another style file by specifying it in `org-cite-export-processors' or
|
||
;; from within the document by adding the file name to "cite_export" keyword
|
||
;;
|
||
;; #+cite_export: csl /path/to/style-file.csl
|
||
;; #+cite_export: csl "/path/to/style-file.csl"
|
||
;;
|
||
;; With the variable `org-cite-csl-styles-dir' set appropriately, the
|
||
;; above can even be shortened to
|
||
;;
|
||
;; #+cite_export: csl style-file.csl
|
||
;;
|
||
;; Styles can be downloaded, for instance, from the Zotero Style Repository
|
||
;; (<https://www.zotero.org/styles>). Dependent styles (which are not "unique"
|
||
;; in the Zotero Style Repository terminology) are not supported.
|
||
|
||
;; The processor uses the "en-US" CSL locale file shipped with Org for rendering
|
||
;; localized dates and terms in the references, independently of the language
|
||
;; settings of the Org document. Additional CSL locales can be made available
|
||
;; by setting `org-cite-csl-locales-dir' to a directory containing the locale
|
||
;; files in question (see <https://github.com/citation-style-language/locales>
|
||
;; for such files).
|
||
|
||
;; Bibliography is defined with the "bibliography" keyword. It supports files
|
||
;; with ".bib", ".bibtex", and ".json" extensions. References are exported using
|
||
;; the "print_bibliography" keyword.
|
||
|
||
;; The library supports the following citation styles:
|
||
;;
|
||
;; - noauthor (na), including bare (b), caps (c) and bare-caps (bc) variants,
|
||
;; - default style, including bare (b), caps (c) and bare-caps (bc) variants.
|
||
|
||
;; CSL styles recognize "locator" in citation references' suffix. For example,
|
||
;; in the citation
|
||
;;
|
||
;; [cite:see @Tarski-1965 chapter 1, for an example]
|
||
;;
|
||
;; "chapter 1" is the locator. The whole citation is rendered as
|
||
;;
|
||
;; (see Tarski 1965, chap. 1 for an example)
|
||
;;
|
||
;; in the default CSL style.
|
||
;;
|
||
;; The locator starts with a locator term, among "bk.", "bks.", "book", "chap.",
|
||
;; "chaps.", "chapter", "col.", "cols.", "column", "figure", "fig.", "figs.",
|
||
;; "folio", "fol.", "fols.", "number", "no.", "nos.", "line", "l.", "ll.",
|
||
;; "note", "n.", "nn.", "opus", "op.", "opp.", "page", "p.", "pp.", "paragraph",
|
||
;; "para.", "paras.", "¶", "¶¶", "§", "§§", "part", "pt.", "pts.", "section",
|
||
;; "sec.", "secs.", "sub verbo", "s.v.", "s.vv.", "verse", "v.", "vv.",
|
||
;; "volume", "vol.", and "vols.". It ends with the last comma or digit in the
|
||
;; suffix, whichever comes last, or runs till the end of the suffix.
|
||
;;
|
||
;; The part of the suffix before the locator is appended to reference's prefix.
|
||
;; If no locator term is used, but a number is present, then "page" is assumed.
|
||
|
||
;; This library was heavily inspired by and borrows from András Simonyi's
|
||
;; Citeproc Org (<https://github.com/andras-simonyi/citeproc-org>) library.
|
||
;; Many thanks to him!
