;;; 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: | |
;; | |
;; - author (a), including caps (c), full (f), and caps-full (cf) variants, | |
;; - noauthor (na), including bare (b), caps (c) and bare-caps (bc) variants, | |
;; - year (y), including a bare (b) variant, | |
;; - text (t). including caps (c), full (f), and caps-full (cf) 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! | |

Thanks, yes, @bdarcus has notified me of the Parsebib changes yesterday. I created a new repo for the patched oc-csl.el
, the latest version there addresses this issue (together with the recent citeproc-el
versions). See https://github.com/andras-simonyi/oc-csl-ns. I plan to remove this Gist in the near future.
Ah cool, I'll redirect my attention there the :) I presume you're still planning on submitting some patches to Org in the not-to-distant future?

Yes, absolutely, as soon as my FSF paperwork arrives.

parsebib-parse-buffer
should beparsebib-parse-bib-buffer
.The old function:
The new function:
(cl-defun parsebib-parse-bib-buffer (&key entries strings expand-strings inheritance fields)
So I think you want
(parsebib-parse-bib-buffer :expand-strings t :inheritance t)
.
