25 | ;;; Commentary: | |
26 | ;; | |
27 | ;; This file implements links to database entries in BibTeX files. | |
28 | ;; Instead of defining a special link prefix, it uses the normal file | |
29 | ;; links combined with a custom search mechanism to find entries | |
33306645 | 30 | ;; by reference key. And it constructs a nice description tag for |
20908596 CD |
31 | ;; the link that contains the author name, the year and a short title. |
32 | ;; | |
33 | ;; It also stores detailed information about the entry so that | |
271672fa | 34 | ;; capture templates can access and enter this information easily. |
20908596 CD |
35 | ;; |

75 | ;; Additionally, the following functions are now available for storing |
76 | ;; bibtex entries within Org-mode documents. | |
77 | ;; | |
78 | ;; - Run `org-bibtex' to export the current file to a .bib. | |
79 | ;; | |
80 | ;; - Run `org-bibtex-check' or `org-bibtex-check-all' to check and | |
81 | ;; fill in missing field of either the current, or all headlines | |
82 | ;; | |
83 | ;; - Run `org-bibtex-create' to add a bibtex entry | |
84 | ;; | |
85 | ;; - Use `org-bibtex-read' to read a bibtex entry after `point' or in | |
86 | ;; the active region, then call `org-bibtex-write' in a .org file to | |
87 | ;; insert a heading for the read bibtex entry | |
88 | ;; | |
89 | ;; - All Bibtex information is taken from the document compiled by | |
90 | ;; Andrew Roberts from the Bibtex manual, available at | |
63aa0982 | 91 | ;; http://www.andy-roberts.net/res/writing/latex/bibentries.pdf |

93 | ;;; History: |
94 | ;; | |
95 | ;; The link creation part has been part of Org-mode for a long time. | |
96 | ;; | |
271672fa | 97 | ;; Creating better capture template information was inspired by a request |
20908596 | 98 | ;; of Austin Frank: http://article.gmane.org/gmane.emacs.orgmode/4112 |
8bfe682a | 99 | ;; and then implemented by Bastien Guerry. |
20908596 | 100 | ;; |
3ab2c837 BG |
101 | ;; Eric Schulte eventually added the functions for translating between |
102 | ;; Org-mode headlines and Bibtex entries, and for fleshing out the Bibtex | |
103 | ;; fields of existing Org-mode headlines. | |
104 | ;; | |
20908596 CD |
105 | ;; Org-mode loads this module by default - if this is not what you want, |
106 | ;; configure the variable `org-modules'. | |
