* org-protocol.el: * org-bibtex.el: Remove remember support. * org-clock.el (org-clock-heading-for-remember): Delete. (org-clock-in): Do not set the heading for remember. Users are encouraged to migrate their remember templates to `org-capture-templates' instead of `org-remember-templates'. See `org-capture-import-remember-templates' on how to ease the transition.

;;; Commentary:
|
||
;;
|
||
;; This file implements links to database entries in BibTeX files.
|
||
;; Instead of defining a special link prefix, it uses the normal file
|
||
;; links combined with a custom search mechanism to find entries
|
||
;; by reference key. And it constructs a nice description tag for
|
||
;; the link that contains the author name, the year and a short title.
|
||
;;
|
||
;; It also stores detailed information about the entry so that
|
||
;; capture templates can access and enter this information easily.
|
||
;;
|
||
;; The available properties for each entry are listed here:
|
||
;;
|
||
;; :author :publisher :volume :pages
|
||
;; :editor :url :number :journal
|
||
;; :title :year :series :address
|
||
;; :booktitle :month :annote :abstract
|
||
;; :key :btype
|
||
;;
|
||
;; Here is an example of a capture template that use some of this
|
||
;; information (:author :year :title :journal :pages):
|
||
;;
|
||
;; (setq org-capure-templates
|
||
;; '((?b "* READ %?\n\n%a\n\n%:author (%:year): %:title\n \
|
||
;; In %:journal, %:pages.")))
|
||
;;
|
||
;; Let's say you want to capture this BibTeX entry:
|
||
;;
|
||
;; @Article{dolev83,
|
||
;; author = {Danny Dolev and Andrew C. Yao},
|
||
;; title = {On the security of public-key protocols},
|
||
;; journal = {IEEE Transaction on Information Theory},
|
||
;; year = 1983,
|
||
;; volume = 2,
|
||
;; number = 29,
|
||
;; pages = {198--208},
|
||
;; month = {Mars}
|
||
;; }
|
||
;;
|
||
;; M-x `org-capture' on this entry will produce this buffer:
|
||
;;
|
||
;; =====================================================================
|
||
;; * READ <== [point here]
|
||
;;
|
||
;; [[file:file.bib::dolev83][Dolev & Yao 1983: security of public key protocols]]
|
||
;;
|
||
;; Danny Dolev and Andrew C. Yao (1983): On the security of public-key protocols
|
||
;; In IEEE Transaction on Information Theory, 198--208.
|
||
;; =====================================================================
|
||
;;
|
||
;; Additionally, the following functions are now available for storing
|
||
;; bibtex entries within Org-mode documents.
|
||
;;
|
||
;; - Run `org-bibtex' to export the current file to a .bib.
|
||
;;
|
||
;; - Run `org-bibtex-check' or `org-bibtex-check-all' to check and
|
||
;; fill in missing field of either the current, or all headlines
|
||
;;
|
||
;; - Run `org-bibtex-create' to add a bibtex entry
|
||
;;
|
||
;; - Use `org-bibtex-read' to read a bibtex entry after `point' or in
|
||
;; the active region, then call `org-bibtex-write' in a .org file to
|
||
;; insert a heading for the read bibtex entry
|
||
;;
|
||
;; - All Bibtex information is taken from the document compiled by
|
||
;; Andrew Roberts from the Bibtex manual, available at
|
||
;; http://www.andy-roberts.net/res/writing/latex/bibentries.pdf
|
||
;;
|
||
;;; History:
|
||
;;
|
||
;; The link creation part has been part of Org-mode for a long time.
|
||
;;
|
||
;; Creating better capture template information was inspired by a request
|
||
;; of Austin Frank: http://article.gmane.org/gmane.emacs.orgmode/4112
|
||
;; and then implemented by Bastien Guerry.
|
||
;;
|
||
;; Eric Schulte eventually added the functions for translating between
|
||
;; Org-mode headlines and Bibtex entries, and for fleshing out the Bibtex
|
||
;; fields of existing Org-mode headlines.
|
||
;;
|
||
;; Org-mode loads this module by default - if this is not what you want,
|
||
;; configure the variable `org-modules'.
