with a front side containing the text "test".
Cards that have been rated as "again" more than eight times and have an ease < 2.0 are considered as leeches .
The ease is included in this classification so that cards can stop being leeches once their review performance has increased.
Leeches should be rewritten or split up into smaller cards to improve the review performance.
- Open Source, works on Linux / BSD
- Org mode syntax for cards
- Easy integration of cards in existing org mode documents (incremental reading)
- Card management & review from inside emacs
- Independent spacing / ease calculation for each node of a cloze card
None of the existing solutions I've seen so far fits these.
org-drill is the one that comes closest and is a elegant solution in that it is fully contained within emacs.
Because ease levels and intervals are stored in the properties of a card, for cloze deletions, a random node is shown at a time and depending on the review result of this node, the interval and ease of the "parent" card are updated.
I'd like to have independent intervals and ease levels for each node of a cloze deletion, because some nodes might be harder to remember than others.
With shared intervals / eases, hard nodes are repeated to rarely and easy nodes are repeated to often.
In addition to that, searching a bunch of org files for cards that are due does not scale well, querying a database is much faster.
Adding a database into the setup can lead to problems where the state of the card in the file is different from the state of the card in the database, but I think the increased flexibility and performance is worth this trade-of.
Simple cards come in two types,
the latter of which is useful for learning the spelling of words.
For each card of type
, two cards are created,
one mapping from front to back, one mapping from back to front.
This is useful for learning words of a foreign language.
Cloze cards have only a front side.
are marked with either
This syntax is inspired by the org mode link syntax.
, the alternative syntax
can be used. This is useful for deletions containing
There are two kinds of cloze cards, deletions and enumerations .
A card is created for each of the nodes, replacing
. The back of this card
of the node.
For deletions, one of the nodes is hidden at a time, for enumerations, one node and all after it are hidden.
For enumerations, nodes other than the current one are shown as
Enumerations are well suited for learning lists of facts where the order is important, e.g. when learning the digits of π.
Combined with inline flashcards, this type of card can be used for incremental reading , wrapping paragraphs of text in inline flashcards and marking relevant pieces of information as nodes.

For the card types "normal" and "double", a horizontal line (
can be used to split the front from the back.
