3.1 Cloze

A cloze note type is a format where you create sentences or paragraphs with “missing” words. A fill-in-the-blanks question.

You can create a cloze note type using ‘M-x gnosis-add-note’ and selecting Cloze, the question should be formatted like this:

{c1:Cyproheptadine::drug name} is a(n) {c2:5-HT2} receptor antagonist used to treat {c2:serotonin syndrome}

You can also format clozes like Anki if you so prefer; e.g {{c1::Cyproheptadine::drug name}}

• For each cX-tag there will be created a cloze type note, the above example creates 2 cloze type notes.
• Each cX tag can have multiple clozes, but each cloze must be a UNIQUE word, or a unique combination of words, in given note.
  • If a cloze is repeated, such as in phrases with “acetyl” & acetylcholine, include whitespace in the cloze to denote a single word.
• You can use the keyword ‘::’ to indicate a hint.

You can remove the guidance string by adjusting ‘gnosis-cloze-guidance’.

3.2 MC-Cloze (Under development)

MC-Cloze is disabled by default, to enable it add to your configuration:

‘(add-to-list 'gnosis-note-types "MC-Cloze")’

A MC-Cloze (Multiple Choice Cloze) is a fill-in-the-blank note, but unlike cloze note type the user is prompted to select an option instead of typing an answer.

You can create multiple notes from one input, but each note can only have one cloze. The first option will always be the right answer (will be randomized in the database), separated by the rest of the answer by ‘gnosis-mc-cloze-separator’ (default value is “&&”), and a note will be generated from each cloze.

Example:

The greatest text editor is Emacs&&Vim&&Helix

When customizing ‘gnosis-mc-cloze=separator’ pay attention to not use values that would mess up with regex functions.

3.3 MCQ

A MCQ note type, as the name suggests, is a multiple choice question.

The stem field (question) is separated by the options (choices) via ‘gnosis-mcq-separator’, each option is separated by ‘gnosis-mcq-option-separator’.

You can remove the guidance string by adjusting ‘gnosis-mcq-guidance’.

3.4 Basic Type

Basic note type is a simple question/answer note, where the user first sees a “main” part, which is usually a question, and he is prompted to input the answer.

3.5 Double

Double note type, is essentially a note that generates 2 basic notes. The second one reverses question/answer.

Ideal for vocabulary acquisition notes.

3.6 y-or-n

y-or-n (yes or no) note type, user is presented with a question and prompted to enter character “y” or “n”.

When using the hidden function ‘gnosis-add-note--y-or-n’, note that the ANSWER must be either 121 (y) or 110 (n), as those correspond to the character values used to represent them.

4.1 Image size

Adjust image size using ‘gnosis-image-height’ & ‘gnosis-image-width’

Example:

(setf gnosis-image-height 300
      gnosis-image-width 300)

4.2 Typos | String Comparison

You can adjust ‘gnosis-string-difference’, this is a threshold value for string comparison that determines the maximum acceptable Levenshtein distance between two strings, which identifies their similarity

Let’s illustrate with an example:

(setf gnosis-string-difference 1)

In this scenario, we set ‘gnosis-string-difference’ to 1. This implies that two strings will be recognized as similar if they exhibit a difference of at most one character edit.

To demonstrate, ’example’ and ’examples’ will be recognized as similar, considering that the latter involves just one additional character."

5.1 Anagnosis Event

Anagnosis, which means comprehension & recognition of knowledge, is triggered when the consecutive successful or failed recalls are equal or greater to anagnosis value.

When anagnosis is triggered by consecutive successful recalls, epignosis value is added to gnosis-plus. Epignosis means accuracy of knowledge.

When anagnosis is triggered by consecutive failed recalls, agnoia value is added to gnosis-minus. Agnoia means lack of knowledge

You can set specific values for each deck and tag of the variables mentioned above by adjusting ‘gnosis-custom-values’.

5.2 Proto

The default initial interval is defined at ‘gnosis-algorithm-proto’, you can define a custom initial interval for each deck as well.

‘gnosis-algorithm-interval’ is a list of numbers, representing the first initial intervals for successful reviews. There is no limit on the length of the list.

Example:

(setq gnosis-algorithm-interval '(0 1 2 30))

Upon each successful note review, the algorithm will increment to the next interval value: 0 days (0), 1 day later (1), 2 days later (2), and 30 days later.

Upon failing to review a note without completing it’s proto successful reviews, it’s next review date will be on the same date.

7.1 Custom Note Types

Each gnosis note type has an interactive function, named ‘gnosis-add-note-TYPE’ and a “hidden” function named ‘gnosis-add-note--TYPE’. You can create your own custom interactive functions to ignore or hard-code specific values by using already defined hidden functions that handle all the logic.

For example:

(defun gnosis-add-note-custombasic (deck)
  (gnosis-add-note--basic :deck deck
                          :question (gnosis-read-string-from-buffer "Question: " "")
                          :answer (read-string "Answer: ")
                          :hint (gnosis-hint-prompt gnosis-previous-note-hint)
                          :extra ""
                          :images nil
                          :tags (gnosis-prompt-tags--split gnosis-previous-note-tags)))
;; Add custom note type to gnosis-note-types
(add-to-list 'gnosis-note-types "custombasic")

Now custombasic is available as a note type, for which you won’t be prompted to enter anything for extra & images.

7.2 Development

To make development and customization easier, gnosis comes with ‘gnosis-test’ module, that should be used to create a custom database for testing.

To exit the testing environment, rerun ‘M-x gnosis-test-start’ and then enter ‘n’ (no) at the prompt “Start development env?”

9.1 emacs-no-littering

If you are a user of emacs-no-littering, you can theme Gnosis to fit its standards by adding the following snippet to your configuration:

(setq gnosis-dir (no-littering-expand-var-file-name "gnosis/"))

This sets ‘gnosis-dir’ to ‘~/.emacs.d/var/gnosis’, in line with the folders of other packages.
