Anki add-on for memorizing lists and enumerations

Cloze Overlapper for Anki

List memorization made easy!

This is an add-on for the spaced-repetition flashcard app Anki. It facilitates memorizing enumerations, lists, or any other type of sequential information by breaking the sequence up into cards where each item serves as the context cue for the next.

Background

Memorizing lists and enumerations has always been a particularly difficult part of studying flashcards. Good flashcards follow the minimum information principle, where each card is kept as short as possible. Sequential information has unfortunately always somewhat eluded that basic principle because it is hard to break down into smaller chunks. Normally you would employ methods like grouping or categorizing to consolidate information, but with each item building upon the next, that does usually not work for sequences or enumerations.

One of the common recommendations in cases like this has always been to create overlapping flashcards, where each card's answer serves as the question prompt for next card in line. For an array of three list items A, B, C you would end up with three cards of the form A → B, B → C, and C → D. What results is chain of overlapping associations between each sequence node that can potentially improve the storage and retrieval strength of the entire sequence.

While this method is generally assumed to be quite effective, following it requires a significant time investment up-front that only few students are able or willing to make.

The Add-on

This is where Cloze Overlapper comes in. It takes care of all the arduous steps required to create these flashcards manually and provides you with a dead-simple workflow: You paste in the sequence or list, adjust the cloze generation settings, and let the add-on generate the cards for you.

More generally speaking, Cloze Overlaper provides Anki with a completely novel cloze system that can cover almost every use case you can think of, be it revealing each taxon of a classification system individually, or even gradually building up to an entire poem:

Due to working with the formatting tools that Anki provides itself, the cards generated by this add-on are fully compatible with all Anki platforms, smartphone apps included:

Installation

AnkiWeb

The easiest way to install Cloze Overlapper is through AnkiWeb.

Manual installation

Please click on the entry corresponding to your Anki version:

Note: Pre-compiled test builds for Anki 2.1 are now available on my Patreon. These will become public once testing is complete.

Anki 2.1

1. Make sure you have the latest version of Anki 2.1 installed. Earlier releases (e.g. found in various Linux distros) do not support .ankiaddon packages.
2. Download the latest .ankiaddon package from my Patreon
3. From Anki's main window, head to Tools → Add-ons
4. Drag-and-drop the .ankiaddon package onto the add-ons list
5. Restart Anki

Anki 2.0

1. Go to Tools → Add-ons → Open add-ons folder
2. Find and delete the Cloze Overlapper.py file if it already exists.
3. See if you can find a cloze_overlapper folder. If so:
   1. If the folder contains a meta.json file, copy the file to a safe location. This will allow you to preserve your current settings.
   2. Proceed to delete the cloze_overlapper folder
4. Download and extract the latest Anki 2.0 add-on release from my Patreon

cloze-overlapper's Issues

Add option to reindex cards in existing note

Checklist

• I've verified that I use the latest version of the add-on by redownloading it from AnkiWeb
• I've verified that I use the latest version of Anki by checking at https://apps.ankiweb.net#download
• I've checked if anyone else suggested this feature before by looking through the issue reports.

Problem case

First a big thanks for developing this useful package. It's been a great help for my study!

I usually uses the tool to recite a paragraph of text, where sequential context matters, so I would cloze selected text one by one:

Lorem ipsum [[oc1::dolor sit amet]], [[oc2::consectetuer adipiscing elit]]. Donec hendrerit tempor
tellus. [[oc3::Donec pretium posuere tellus]]. Proin quam nisl, [[oc4::tincidunt et]], [[oc5::mattis
eget, convallis nec, purus.]] Cum sociis natoque penatibus et magnis dis
parturient montes, [[oc6::nascetur ridiculus mus]]. Nulla posuere. [[oc7::Donec vitae dolor]].
[[oc8::Nullam tristique diam non turpis]]. Cras placerat accumsan nulla. [[oc9::Nullam rutrum.]]
[[oc10::Nam vestibulum]] accumsan nisl.

And this generates 10 cloze cards and a full card.

Now during my review session, I sometimes find the original cloze is too coarse, and I would like to break it down into finer pieces. For example, breaks consectetuer adipiscing elit at oc2 into consectetuer and adipiscing elit. My expected result is:

• New cards [[oc2::consectetuer]] and [[oc3::adipiscing elit]] added, old [[oc2::consectetuer adipiscing elit]] removed
• Index of cards that are after the change are added by 1: Original [[oc3::Donec pretium posuere tellus]] becomes [[oc4:Donec pretium posuere tellus]], and original [[oc4:...]] becomes [[oc5:...]], and so on.

11 cloze cards are generated with a new full card.

Solution

Concisely describe the solution you would like

A command to reindex all clozes based on their position.

Concisely describe alternatives you've considered (if any)

Currently, if I remove [[oc2::...]] and use shortcut Ctrl+Shift+C to cloze adipiscing elit, cloze overlappers would use the maximum index (10) and generate [[oc11::adipiscing elit]]. During review then, the context before [[oc11::adipiscing elit]] is considered to be [[oc10::Nam vestibulum]] instead of [[oc2::consectetuer]], so sequential context is lost.

The only way I can achieve this result, for now, is to remove [[oc2::...]], add [oc3::], and manually edit index in all subsequent cards from oc3 to oc10. Disadvantage: becomes tedious when there are many clozes to change.

Yet another solution: remove subsequent clozes one by one, and re-cloze them so they are in the desired order. It's a slight improvement over manual editing. (Side note: I suspect this should work, but the Alt+Shift+R shortcut to remove cloze in selected text, as I have seen in Wiki/Usage, does not work for me. It simply inserts "R" in text box.)

Yet another solution: Break the whole paragraph into lines to utilize the automatic index behavior in list clozes. Disadvantage: it would not look great at all for a paragraph of text.

Again, thanks for the gorgeous plugin!

Can't resize the Options window, text does not fit

Prerequisite checklist

• In case of a bug: Have you tried restarting Anki?
• Are you running the latest version of the add-on. Have you redownloaded the add-on from AnkiWeb to make sure?
• Did you check the add-on documentation (e.g. AnkiWeb description, Wiki if it exists) for known issues?
• Did you perform a cursory search through the existing issue reports?

What is the problem/feature you would like to see fixed/implemented?

Many strings do not fit in their space in the window. Pulling a window corner moves the window, unlike with Firefox or Anki.

How can we reproduce the problem?

[What were you doing when the problem occurred?]

1. Set the Qt4 font to DejaVu Sans Book size 12 or 14 (using qtconfig-qt4).
2. Open Cloze Overlapper Options.

Expected behavior:

Text fits, as there is plenty of space on the screen for the window to grow.

If the window can't grow on its own, I can resize it.

Actual behavior:

Neither of the above.

Reproducible?:

Yes.

Improve support for HTML tags

Awesome add-on.
It could be more awesome if html can be overlapped say tags. The use of this is obvious. Think about wanting to learn and memorize origami through sequence of picture.

Do not show success message if notes not added

E.g. scenario:

• user has added an additional field in position 1
• field 1 is empty when adding note, whereas original field is filled out

Expected behavior:

• no confirmation message from add-on on added notes

Actual behavior:

• confirmation message regardless of whether note creation succeeded or not

Note: we do account for an empty Original field (because it's usually at position 1). But in corner cases where users have modified their templates the add-on does not behave as expected in this scenario.

Customize Keyboard Shortcuts conflicts with modified cloze hotkey

Caused by Liresol/anki-custom-shortcuts@daa0edc

Editor.onCloze – which Cloze Overlapper wraps – is no longer assigned in favor of a duplicated CKS-specific cloze method. Working around this fact is possible, but hacky. As other add-ons like Enhanced Cloze are also affected, it would be more sensible for CKS to fix this on their side.

Possible enhancements to the Toggle List feature

I really appreciate that you included the feature to toggle ordered and unordered lists. I think your add-on does a better job with lists than the "Power Format Pack" add-on, which I've consequentally deleted. However, there are a few ways I think the list feature could be improved:

1. Currently every line of text becomes a list item when a Toggle List hotkey is pressed. But sometimes I only want parts of the text to be formatted as a list. Would it be possible to introduce the following behavior when a Toggle List hotkey is pressed: if no text is selected, toggle list formatting for all lines; but if only some text is selected, then toggle list formatting for only those lines.

   (Because this suggestion requires you to no longer assume that the user wants every line to be a list item as well as a cloze deletion, it might make sense to de-link toggling list formatting and generating overlapping clozes.)

2. I'd love to be able to use the list feature of this add-on even for other note types. It seems this might be possible if you made toggling list formatting and generating overlapping clozes independent commands. That way, the "Reminder: can only generate overlapping clozes ..." warning would only appear when attempting to generate overlapping cloze. Meanwhile, the user could toggle list formatting freely when working with other note types.

Thanks as always for your great work!

Mathjax problem - false alert

Oops, it turns out it was the case of a dumb user. First of all, the problem also occured with regular clozes, and second, could be avoided by adding more whitespace around the < and >.

Problem description

Trying to cloze overlap cards with Mathjax which include < and > symbols. Cloze overlapper shows them in the answer correctly when they are written out as </> - but then they will be shown as error once "Reveal all clozes" is pressed - and basically vice versa.

The issue persists when all add-ons are disabled (please forgive having them toggled on in the screenshot), it surely is some bug in note template.

Cloze button generates Anki cloze markers rather than overlapping cloze markers

Using the cloze button will currently create Anki clozes ({{c1::) rather than the add-on's clozes ([[oc1::]]). This issue does not appear when using the cloze hotkeys.

(thanks to Gabriel for the report!)

JSONEncodeError when saving settings on Anki 2.1.26+

Anki 2.1.26+ changes how col.conf operates, so we need to adjust config getting/saving accordingly.

Implement automatic unsuspend when suspend option active

Ideally we would have the full cloze appear once all regular clozes have graduated from learning.

Or, with a more sophisticated implementation: After all regular clozes have reached at least an interval of X days, with X being user-customizable.

Option to limit the number of ellipses

Prerequisite checklist

• Are you running the latest version of the add-on. Have you redownloaded the add-on from AnkiWeb to make sure?
• Did you check the add-on documentation (e.g. AnkiWeb description, Wiki if it exists) for known issues?
• Did you perform a cursory search through the existing issue reports?

What is the problem/feature you would like to see fixed/implemented?

I think all the ellipsis characters provide unnecessary context if you need the association between the previous and the current items not based on their position in a long list (especially relative to a very far end). There could be a way to limit the amount of them like there is with "Context Before" and "Context After".

How can we reproduce the problem?

1. Generate clozes out of a long list.

Expected behavior: [What you expected to happen]

First line
{{c1::Second line}}
...

or at most

First line
{{c1::Second line}}

Actual behavior: [What actually happened]

error when loading plugin

I ahve installed the plugin and whenever i start anki i get this.
https://imgur.com/KfdUquL
how do I fix this ?

Hint reveal hotkey interferes with Image Occlusion's "Toggle Masks" and can't be changed in the UI.

Toggle Masks in IO didn't work anymore for me after the introduction of the hint reveal hotkey in cloze overlapper.
I never tried if the hint reveal hotkey for cloze overlapper works when IO is installed too.

Changing the hint reveal hotkey to "h" in reviewer.py fixed the problem for me, but imo this should be in the config dialog.

Option to require confirmation before automatically changing text fields

Prerequisite checklist

• In case of a bug: Have you tried restarting Anki?
• Are you running the latest version of the add-on. Have you redownloaded the add-on from AnkiWeb to make sure?
• Did you check the add-on documentation (e.g. AnkiWeb description, Wiki if it exists) for known issues?
• Did you perform a cursory search through the existing issue reports?

What is the problem/feature you would like to see fixed/implemented?

On a press of a button and even some other actions (review or note edit?) after editing the Original field, CO updates any text in the note fields, including text that I have entered or edited myself. It should ask for a confirmation.

It is a possible serious dataloss for me, because I add pictures for almost every cloze (bus routes). To avoid it, I would have to add a Pre field and a Remarks/Extra field for each cloze field.

How can we reproduce the problem?

1. Enter "123\n456" into Original and abc into Text1.
2. Press CO's [.] button. It also happens without pressing any button, if the Original field was edited.

Expected behavior:
A confirmation request.

Actual behavior:
The abc was overwritten with {{c1::123}}\n... silently.

Reproducible?:
Yes.

Version information

Anki Version 2.0.52
Qt 4.8.1 PyQt 4.9.1

Wrong tool tip for "Don't generate full cloze"

Small issue: the tool tip for "Don't generate full cloze" in the Overlapping Cloze Note Settings seems to be wrong. (It's identical to what I see when hovering my mouse over "No cues for first item".)

My mouse disappeared from the screenshot, but I was hovering over "Don't generate full cloze".

Scroll to the cloze spot?

Great add-on. I was trying anki cloze, but it doesn't scroll to the cloze spot in long articles. I find a solution on Reddit which leads me here. Does the scroll function work or just me?

Wiki says the default card prefix is "ol-cloze", but it's "cloze-ol". It also mentions Deck Override, but that's not available.

https://github.com/Glutanimate/cloze-overlapper/wiki/Customization#ankis-cards-dialog

Also, I didn't know that was the card prefix and was looking for it in the templates and styling fields. So please mention that it's at "More → Rename".

But there is actually no "More → Deck override" for Cloze types, at least in Anki 2.0.x.

How to update notes?

I notice a typo in a cloze note, so I update it. Except that the Text1,Text2, etc. fields do not update to reflect that change. Can I force them to update?

When will this addon available for Anki 2.1?

When will this addon available for Anki 2.1? I was able to build the addon using aab and install it. But I got errors after restarting Anki informing missing forms files

Note ID AssertionError when adding notes on Anki 2.1.28+

Problem description

When creating new notes with overlapping clozes, there is an AssertionError (see below), because there is no id for the new note yet.
I think that the issue was introduced with ankitects/anki@f637ac9#diff-4a37772b551db2baaf677e04d51a3c04, but I'm not sure.

Error building from source

I read on here that you could build the addon from source, so I downloaded v0.4.0-alpha.0 from the tags page. Then I ran make on the root directory. Instead of building the addons, it returned some errors.

Cloze deletion single card error when adding to deck

Problem description

The smallest example I can find where the error is reproduced is the following:

In short I believe the add-on currently doesn't support single cloze card design.
One useful application would be tables, in which I would like to reveal multiple fields at the same time.
The fields seem to be correctly populated but adding the card to the deck fails with the error below.
This issue is present only when creating/adding new cards, and not when editing existing ones.

Not generating continuous cloze captions

After reinstalling Anki with the Cloze overlapper plug-in, I am not able to generate multiple close captions (oc1, oc2, etc.) Instead both the shortcut Ctrl-Shift-C and the generate caption button on the toolbar are only generating {{c1::}} captions.

Show Original is not working with LaTeX

I want to use the cloze-overlapper addon and LaTeX together. The following example works fine except that somehow the cloze syntax does not get removed from the Show Original hint.

[latex]
\section*{Bernoulli's Inequality}

For any real number $x$ [[oc1::$> -1, \, x \neq 0$]] and any integer $n$ [[oc2:: $\geq 2$]] we have
[[oc3::$$(1+x)^n > 1+nx.$$]]
[/latex]

I would be very grateful for any help.

Sincerely, Vincent

Error message while adding cards in Anki 2.1.33

IMPORTANT

The easiest fix that I found online was to downgrade to 2.1.26 which actually worked for me so yay! But one person in Glutaminate's Patreon & another on this thread commented that his error still persisted after downgrading to 2.1.26.

Thank you!

Problem description

Error message pops up when trying to add a cloze overlapper card in Anki 2.1.33. The error also pops up if -

1. I go to Tools > Cloze Overlapper Options > Clicking on Ok.

2. While in the process of adding a card, before actually adding it, clicking on the settings icon to open the cloze overlapper settings window, and clicking Ok.

Ability To Type in Cloze

I'm not sure where you want features such as this @glutanimate.

The ability to type in the cloze would be helpful at times. I'm not sure how difficult it would be to implement it with this addon though. I've tried a few {{type:cloze:}} combinations, but it doesn't look like it's going to be that simple.

I'll look into this later when I have time to dig into the code.

I would really appreciate your help!

Cloze overlapping for "Strip HTML when pasting text"

Hi,

I'm trying to use cloze overlapping under the preference "Strip HTML when pasting text", but when I try to do this I get a message stating there are too many Cloze overlaps generated. I use the "Strip HTML when pasting text" preference because it allows me to copy and paste with the original formatting from Microsoft word (i.e. with colour etc). Is there anything I can do to be able to use Cloze Overlapping with the "Strip HTML when pasting text" preference?

Custom Study with "mark" clozes

Hi Glut!
I'm searching a solution for custom study for cloze overlapper

The problem is:
Is there a way to create a custom study for the clozes i've marked?
Because when i "mark" a card, anky "mark" all the clozes, i only want the specific ones

Here is an exemple

Question1
[oc1::Asw1] (i need to MARK it/Specif Tag )

Question2
[oc2::Asw2]

Question3
[oc3::Asw3]
.
Etc..

Does this work with 2.1.29 or 2.1.26?

Your question

It is mentioned in the readme file that it used to be a stand alone script. Can I use it as such with this release?
The issue is that I could not get it to run in anki, It seems that there are some fundamental issues that are still not fixed and I am not able to build the add-on since I am using windows.

2.1 support

Since Anki 2.0 support is ending in 2020.

(feature request) Add custom Cloze-overlapping Note type

I want to configure custom styles per deck, but it seems not supported.
It would be quite useful to be able to add custom Note type for cloze overlapping.

Please make this compatible with Anki 2.1.x

Problem description

As readme states, i must drag-and-drop .ankiapp into addons list. Sadly i cannot find a file or folder with that name in latest release of this addon.

Problem description

Please describe the issue concisely in here. In case of an error: Walk us through the steps you took to get there. What happened? What did you expect to happen?
I was trying to generate overlapping clozes with this add-on but however when i clicked on the button, an error shows up. I've done what Anki recommended which is to hold shift while starting anki. The problem does go away then but whenever i clicked on the button again, the same issue persists.
