[Userscript] Memrise Autocorrect (diacritics, punctuation, case)

Thank you for this script! If anyone is interested, I improved it a little in terms of events (compositionstart wasn’t working for example):

$(‘body’).on(’.typing input’, ‘input’, function() {
processInput();
});

$('body').on('select', function() {
    processInput();
});


function processInput () {
    var b = MEMRISE.garden.box,
        p = b.testData.correct,
        i = b.$input.input || b.$input,
        v = i.val(),
        sliceIndex = 0;

    for (let a of p) {
        if (a.indexOf(v) !== 0) {
            var aNoDiacritics = getNonDiacritics(a).toLowerCase();
            var aSimple = getNonPunctuation(aNoDiacritics);
            var vSimple = getNonPunctuation(getNonDiacritics(v)).toLowerCase();

            if (aSimple.indexOf(vSimple) === 0) {
                var noDiacriticSliceIndex = aNoDiacritics.match(new RegExp(`.*?${vSimple.split("").join(".*?")}((${punctuation.source}|\\s)+$){0,1}`))[0].length;
                var counter = 0;
                for (let i = 0; i < a.length; i++) {
                    counter += getNonDiacritics(a[i]).length;
                    if(counter <= noDiacriticSliceIndex) sliceIndex++;
                    else break;
                }
            }
        } else {
            try{
                sliceIndex = a.match(new RegExp(`${v}((${punctuation.source}|\\s)+$){0,1}`))[0].length;
            }catch(e){
                console.log(e);
                //break;
            }
        }

        if (sliceIndex) {
            var replacement = a.slice(0, sliceIndex);
            i.val(replacement);
            if(v !== replacement) {
                console.log(v);
                console.log(replacement);
                $('.typing-type-here').trigger('keydown');
            }
            break;
        }
    }
}
