Allow specifying field values from org-mode properties (#22) 
* Allow specifying field values from org-mode properties

* Update documentation and fine-tune the diff

* Refactor, fix indentation, and other minor fixes

Renamed all-fields to named-fields since the heading and content
before first subheading can also be a field.

* anki-editor
anki-editor is an [[https://www.gnu.org/software/emacs/emacs.html][Emacs]] minor mode for making [[https://apps.ankiweb.net][Anki]] cards with [[https://orgmode.org][Org Mode]].
This repository is a fork of [[https://github.com/louietan/anki-editor][louietan/anki-editor]]. By now there are quite a few differences and extensions compared to the original:
- The develop branch of the original has been merged into the master branch; see the unreleased section of [[https://github.com/orgtre/anki-editor/blob/master/Changelog.org][Changelog.org]] for a list of the new features that come with this.
- Almost all outstanding pull requests to the original have been integrated; [[https://github.com/orgtre/anki-editor/issues/10][this issue]] tracks the two exceptions.
- A more flexible note structure, outlined [[https://github.com/eyeinsky/org-anki/issues/48#issuecomment-1216625730][here]], has been introduced.
- The commands to push notes, delete notes, and insert notes have been improved.
- A [[https://github.com/orgtre/anki-editor/issues/13][transient interface]] to all commands has been created.
See the [[https://github.com/louietan/anki-editor/compare/master...orgtre:anki-editor:master][commit log]] for a full list of differences. Note that this README does not reflect all the changes and additions yet.
** Installation
*** External dependencies
Other than Emacs you need [[https://apps.ankiweb.net][Anki]], its [[https://github.com/FooSoft/anki-connect][AnkiConnect]] add-on, and [[https://curl.se][curl]] to use anki-editor. Because of AnkiConnect, anki-editor-mode needs Anki to be running (see [[https://github.com/orgtre/anki-editor/issues/5#issuecomment-1295857747][issue]] for explanation).
*** Using package.el
If you're using the built-in =package.el= package manager, first manually download this repository and then type the following in Emacs:
: M-x package-install-file [RET] "path/to/anki-editor.el" [RET]
You can also first visit =anki-editor.el= in an Emacs buffer and then type =M-x package-install-from-buffer [RET]=. Both will install the anki-editor package, including uninstalled Elisp dependencies, into =package-user-dir= (=~/.emacs.d/elpa= by default), generate autoloads, and set up =load-path=.
*** Using straight.el
If you're using [[https://github.com/radian-software/straight.el][straight.el]] as package manager, install by adding this to your =init.el=:
#+begin_src elisp
(use-package anki-editor
:defer t
:straight (:fork "orgtre"))
#+end_src
** Usage
*** The Layout of Notes
The power of this mode comes from the builtin HTML export backend
provided by Org, which enables you to use almost all the Org
constructs for writing Anki notes: lists, code blocks, tables,
latex and so on.
The structure of a note is as follows, which is inspired by
~org-drill~. Check out [[./examples.org][examples.org]] for more examples.
#+BEGIN_SRC org
,* Raining :vocab:idioms:
:PROPERTIES:
:ANKI_DECK: English
:ANKI_NOTE_TYPE: Basic (and reversed card)
:ANKI_TAGS: vocab idioms
:END:
,** Front
(it's) raining cats and dogs
,** Back
it's raining very hard
,* Is there a shorter way to write notes?
:PROPERTIES:
:ANKI_NOTE_TYPE: Basic
:END:
,** Back
Yes, like this one, Front is missing, ~anki-editor~ will use note
heading as Front. This is neat as sometimes it's verbose to repeat
the same content in note heading and first field.
This works for all note types, just make one field absent and
~anki-editor~ will use note heading as that missing field.
,* Is there a an even shorter way to write notes?
:PROPERTIES:
:ANKI_NOTE_TYPE: Basic
:END:
Yes, like this one, Front and Back is missing, ~anki-editor~ will use note
heading as Front and the text after as Back. This is neat as sometimes it's verbose to repeat
the same content in note heading and first field.
This works for all note types, just make the first 2 fields absent and
~anki-editor~ will use note heading as first field and the text below the heading as second field.
,* You can extract a field value from an org-property
:PROPERTIES:
:ANKI_NOTE_TYPE: Basic
:ANKI_FIELD_FRONT: Can one define an anki-field inside an org-mode property?
:ANKI_PREPEND_HEADING: nil
:END:
Yes. In this example, =anki-editor= will use the =ANKI_FIELD_FRONT= property value as
a front side of the Anki card and the body of the card as its back.
,** Front
Notice that property fields will override subheading fields.

#+END_SRC
- Anki deck is provided by ~ANKI_DECK~ property. This property is
retrieved with inheritance, that is to say, it can be put in any
ancestor entries or at top of the file by ~#+PROPERTY: ANKI_DECK
DeckName~.
- ~ANKI_NOTE_TYPE~ property is to specify the Anki note type of a
note and is also required for identifying an Anki note entry.
- Anki tags can be provided in two ways:
1. With a ~ANKI_TAGS~ property, multiple tags are separated by spaces
2. With Org tags [fn:1], this could be turned off if you would
like to keep Org tags separated from Anki tags
- Child entries of a note entry are fields.
Typing all these information by hand could be inefficient and prone
to errors, so this package provides an interactive command
~anki-editor-insert-note~ to help with this and hooks up
auto-completions for decks, note types and tags etc.
[fn:1] It should be noted that Org only allows letters, numbers, =_=
and ~@~ in a tag but Anki allows more, so you may have to edit you
Anki tags before they can be used in Org without any surprise.

*** Functions and Macros
**** anki-editor-map-note-entries
Simple wrapper that calls ~org-map-entries~ with
~&ANKI_NOTE_TYPE<>\"\"~ appended to MATCH.
**** anki-editor-api-call
Invoke AnkiConnect with ACTION and PARAMS.
**** anki-editor-api-call-result
Calls above, returns result field or raise an error.
**** anki-editor-api-with-multi
Used in combination with ~anki-editor-api-enqueue~ to queue
multiple api calls and combine them into one 'multi' call at the
end, return the results of these calls in the same order.
Usage:
#+begin_src elisp
(cl-destructuring-bind (decks models tags notes)
(anki-editor-api-with-multi
;; The following api calls will be combined into one 'multi' call.
(anki-editor-api-enqueue 'deckNames)
(anki-editor-api-enqueue 'modelNames)
(anki-editor-api-enqueue 'getTags)
(anki-editor-api-enqueue 'findNotes :query "deck:Default"))
(message (concat "decks: %S\n"
"models: %S\n"
"tags: %S\n"
"notes: %S")
decks models tags notes))
#+end_src
**** anki-editor-api-enqueue
Like ~anki-editor-api-call~, but is only used in combination with
~anki-editor-api-with-multi~. Instead of sending the request
directly, it simply queues the request.
**** anki-editor-note-at-point
Make a note struct from current entry.
**** anki-editor-find-notes
Find notes with QUERY.
**** anki-editor-copy-styles
Copy `org-html-style-default' and `anki-editor-html-head' to Anki card stylings.
**** anki-editor-remove-styles
Remove from card stylings html tags generated by this mode.
** Limitations
*** Tags between Anki and Org
Because the set of characters allowed in tags is different between
Anki and Org, you have to make sure that tags from Anki are
compatible with Org and tags in Org could be recognized by Anki.
*** Working with Anki add-ons
This package might not work well with certain Anki add-ons
especially those who extend the builtin Anki note editor to
automatically fill note field content (e.g. ~Add note id~).
*** One Way Sync with Anki
To sync anki notes and decks to org see ([[https://github.com/orgtre/ankiorg][orgtre/ankiorg]]).
The following items are not synchronized to org:
- Deletion of Notes
- Deck Changes
