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

Thanks for a great script!

In case this was bothering anyone else, quick-and-dirty centering of “Item info” button so the “Need help?” arrow points to the correct button (with seven buttons showing).

$("#option-item-info")[0].nextSibling.after($("#option-item-info")[0])

Q: Should it be adjusted only for the “Need help?” message, or all of the pop-up messages?
(other messages include “multiple answers”, “a bit off”, “Wanikani is looking for the…”)

I’d guess all.

I just came across a problem with the reading/meaning confusion check:
wanakana.toKana("sennenn") results in せんねん instead of せんえん, which I would have expected. Therefore answering with “sennenn” for the 千円 meaning question is not recognized as a reading/meaning mistake.

I have added a bugfix for this:

Thanks for the fix!

After looking at it, I think I only needed to replace:

var answer_as_kana = wanakana.toKana($('#user-response').val());

with:

var answer_as_kana = wanakana.toKana($('#user-response').val(), {IMEMode:true});

I was only able to test this in the Javascript Console, and it worked fine. If you know of additional cases that this won’t address, please let me know :slight_smile:

Really? In my tests, adding {IMEMode: true} wasn’t enough.

Have you tested it with WanaKana version 1.3.7 (the one used by WaniKani on the review page)? I think the up-to-date version of WanaKana behaves differently in this case.

Ahh, Wanakana version may be the issue. This is how I tested:

I’ve updated with your exact fix, and added an attribution in the code. Thanks again!

The attribution wasn’t really necessary since it was me in the first place who introduced this bug when I implemented the reading/meaning confusion check feature, but thanks nonetheless :smiley:

It’s time I didn’t have to spend debugging :slight_smile:
Also, I’m glad for the “reading/meaning confusion” feature as well, even if I didn’t think to add attribution at the time.

Sorry, my to_kana() function also contains a bug – it throws an error if the passed string is empty (which happens whenever the user tries to submit an empty answer to a meaning question). Here is the updated function:

    function to_kana(text) {
        return Array.from(text).reduce((total, c) => wanakana.toKana(total + c, {IMEMode: true}), "").replace(/n$/, String.fromCharCode(12435));
    }

I was excited to finally try this script, had been using “ignore” all this time - especially because I wanted to sometimes mark an answer as wrong that Wani recognized as correct by mistake.

I like its functions but I ran into a big problem right away in a short 15 reviews session:
It happened to me at least 4 times during this very short review sesson (in which I purposely got stuff wrong to test the script) that after I click “retry”, it was no longer possible to enter any text! The input window just turned grey!
Sometimes that happened right away, sometimes it took a second where I could still enter like one letter before that happened.
The only way around it was to refresh the webpage but for obvious reasons I do not feel happy with using a script when that is such a frequent occurence.

I tried scanning this topic briefly for anybody else this happened to but couldn’t find anything.
I hope anybody can help, I really wanna use this but as it is now, I gotta stick to the “ignore” script.

EDIT: I disabled the ignore script because I heard that there might be issues if both run at the same time.

I have this happening to me all the time, but I haven’t bothered to make a report here. What works for me usually is clicking the submit button with the mouse and then backspacing. Sometimes I need to click the input space to presumably get focus. I’ve noticed this happens a lot when I input a bit too fast, and it’s quite annoying. No idea what’s causing it, though. On firefox myself.

Hmm okay, I wonder if the dev knows about this? Surely this can be fixed!

I can produce a similar issue caused by the mistake delay: if I get an answer wrong, press escape, retype the answer, and then try to submit the retyped answer before the mistake delay is over, the input box becomes greyed out. However, this bug seems a bit different than your experience.

Anyway, my bug can be fixed by setting ignore_submit to false if the answer gets reset:

[...]
function set_answer_state(answer, show_msgs, no_redraw) {
	// If user requested to retype answer, reset the question.
	if (answer.reset) {
		ignore_submit = false;
		[...]

Please post your settings for Double-Check, and I’ll see if I can replicate the issue here.
It may be a few days before I can look into it, though.

I left everything on default except for on the first page of the settings where I enabled marking answers as wrong, and as correct.

@rfindley Thanks for the script. I have a quick question: what happens when I’ve made a mistake previously but accidentally moved forward with the wrong answer? If I see that same item again, is there anyway to remove the mistake made previously?
