[Userscript]: Double-Check (Version 2.x)

@rfindley The regression seems to be caused by the fact that WaniKani is now calling Howler.unload() every time the question changes. I fixed this by replacing the function with a version that only unloads audio that is not playing / queued to play. I also fixed two other bugs: the class name issue and the issue with audio playing twice sometimes. The audio playing twice issue was fixed by calling wkRefreshAudio() when the answer state is reset under some but not all circumstances (see code).

Just want to verify it’s not just an issue with this user’s setup; all of the above is true for me too.

FYI:

Version 2.2.27 backspace or Esc not working to allow retyping answer.

Downgrading to version 2.2.24 is appears to be working.

It seems like Wanikani is sometimes showing the wrong prompt when this script is installed now, I tried downgrading to 2.2.24 but the issue is still there. After you hit enter with a blank input, the prompt will change to the correct prompt.

Edit: I narrowed it down to only happening when there is supposed to be a Kanji input. With the blank input line, you can spam the enter key and it will change prompts with each hit until a meaning prompt is shown.

Edit2: Wrong answers on reading inputs are being counted as correct and traversing like you are in lightning mode. Empty inputs just jump to a new prompt.

The new update seems to have triggered this =)

This script makes WK usable for my dyslectic ADHD mind, so going on vacation till solved :crazy_face::rofl:

Error in this script now. It appears to be mimicking lightning mode and breezing past the readings, whether right or wrong, with no indication with correct or not. I attempted to downgrade to several previous versions and couldn’t get it to work.

Also: thank you SO much for this script! it’s so wonderful, and SO appreciated! The amount of work you put into it is wonderful, and so are you! =D

It wasn’t the new update since it was working fine last night. It seems like Wanikani updated something thats causing this.

I only first noticed it today as well, but after testing by several it seems to only happen with this script active, while others disabled.
The update might have been good at first, and a new change by WK created the problem.
Nothing is conclusive, but it seems probable

Having tested multiple versions of this script today and having the same issue occur, I think its safe to conclude that it’s not the most recent update of the script but something changed on Wanikani’s end.

Yes, but we agree it happens only with this scrip, even if not caused by the new update then.
Which just makes it harder to fix… Had it been the new version it could have been easier to know what caused it (or change back to old version)

See Many iems marked right no matter how wrong - #33 by est_fills_cando for information about the current issues.

Same issue with me, i’m used to pressing enter twice (and if i’m wrong, it’ll stop me) and now sometimes pressing enter will advance like 2-3 readings/meanings, right or wrong. I haven’t touched the scripts in a very long time so it’s definitely a change on WK’s end.

Here is a version that I think fixes the issues people are having with incorrect answers being marked correctly. I made this fix pretty quickly, so please let me know if you encounter any additional bugs.

Also, if you use this fix or any other fix that involves needing to copy + paste a script, make sure to re-enable automatic updates if you use TamperMonkey. (Copying and pasting a script in TamperMonkey causes automatic updates for that script to be disabled, but you can reenabling them by going to the settings tab for the script.)

Edit 2: An official fix from the author of DoubleCheck has been posted, so you should just be able to update DoubleCheck instead of using the script below and it should be fixed when you do that.

Yep, I just published essentially the same fix. Wanikani removed filterAuxiliaryMeanings() from the answerChecker. Thanks for working so quickly to get people back up and running!

Hmm… it’s still working fine for me. But try the update that I just posted to fix unrelated issues.

Oh that was quick!
Thanks for the great work! :smiling_face_with_three_hearts:

I first got “reinstal” instead of update (which didn’t help)
Restarted Chrome to get “Update” instead
Not sure what was up with that XD

Tested, it works! Thanks! :smiling_face_with_three_hearts:

I had to copy the code since it would neither update nor reinstall, but the update itself works like a charm. Big thanks for everyone involved to get this bug reported to the right people and ofc for the fix :slight_smile:

Thank you for the quick update, this script is a lifesaver with how often I make typos.
