magento2: Magento 2.2.0: Translations for 'Item in Cart' missing in mini cart.

The reason why some strings are not translated is because they are by default only in html files in tags like

<translate args="'Item in Cart'" if="getCartLineItemsCount() === 1"/>

The Magento Translation module has four different patterns it uses to detect translatable phrases. Only the translations for strings matching these patterns are translated into the js-translation.json. You can see the patterns in Magento/Translation/etc/di.xml. Unfortunately none of those patterns match the translate args tags.

To fix this without needing to explicitly call for a translation on all the missing phrases, you can add the following lines into pretty much any module’s di.xml:

    <type name="Magento\Translation\Model\Js\Config">
        <arguments>
            <argument name="patterns" xsi:type="array">
                <item name="translate_args" xsi:type="string"><![CDATA[~translate args\=("|'|"')([^\'].*?)('"|'|")~]]></item>
            </argument>
        </arguments>
    </type>

This adds a pattern that matches the translate args tags to the translation config.

@magento-engcom-team Suggested fix for the issue is to add the above pattern (or something similar) to the relevant part of Magento/Translation/etc/di.xml.

I added file cart-items.html and this code. Now “Item in Cart” translating for different language works.

<div class="title" data-role="title">
    <strong role="heading"><span data-bind="text: getItemsQty()"></span>
        <!-- ko if: getItemsQty() == 1 -->
        <!-- ko i18n: 'Item in Cart' --><!-- /ko -->
        <!-- /ko -->
        <!-- ko if: getItemsQty() > 1 -->
        <!-- ko i18n: 'Items in Cart' --><!-- /ko -->
        <!-- /ko -->
    </strong>
</div>

hi, any of solutions provided above doesnt work for me (M2.2.2). does anybody have working solution? thanks in advance!

The problem is that there was not js translation before <translate> tag.

I solved it temporary by overriding template src/vendor/magento/module-checkout/view/frontend/web/template/minicart/content.html

and add there js translation:

<div class="items-total"> to 
<div class="items-total" data-translate-hidden="attr: { item_in_cart: $t('Item in Cart') }"

you can use any name for attribute here.

This solution works for me.
