;; Description: Make Anki Cards in Org-mode
|
|
;; Author: Lei Tan

;; Version: 0.3.3

;; Package-Requires: ((emacs "25") (request "0.3.0") (dash "2.12.0"))

;;; Commentary:
|
|
;;
|
|
;; This package is for people who use Anki as SRS but would like to
|
|
;; make cards in Org-mode.
|
|
;;
|
|
;; With this package, you can make cards from something like:
|
|
;; (which is inspired by `org-dirll')
|
|
;;
|
|
;; * Item :emacs:lisp:programming:
|
|
;; :PROPERTIES:
|
|
;; :ANKI_DECK: Computing
|
|
;; :ANKI_NOTE_TYPE: Basic
|
|
;; :END:
|
|
;; ** Front
|
|
;; How to hello world in elisp ?
|
|
;; ** Back
|
|
;; #+BEGIN_SRC emacs-lisp
|
|
;; (message "Hello, world!")
|
|
;; #+END_SRC
|
|
;;
|
|
;; This package extends Org-mode's built-in HTML backend to generate
|
|
;; HTML for contents of note fields with specific syntax (e.g. latex)
|
|
;; translated to Anki style, then save the note to Anki.
|
|
;;
|
|
;; For this package to work, you have to setup these external dependencies:
|
|
;; - curl
|
|
;; - AnkiConnect, an Anki addon that runs an HTTP server to expose
|
|
;; Anki functions as RESTful APIs, see
|
|
;; https://github.com/FooSoft/anki-connect#installation
|
|
;; for installation instructions
