Some platforms and file formats provide support for “plurals”. For example, Android has Quantity Strings and gettext allows to store plural translations in PO files that are accessed using ngettext. iOS has the stringsdict file type which is dedicated to plural strings.

mojito follows CLDR standard to manage plurals.

The mapping is straight forward for platforms that also use CLDR like Android. For gettext, a mapping is required between CLDR forms and gettext indices.

Mojito’s Workbench

In mojito workbench, plural text units are easily identified with the CLDR form displayed as a label next the locale label. Clicking on the plural label opens the workbench with all different plural forms.

Depending on the locale, the forms shown are customized. For example, while English has 2 forms (singular and plural), Japanese has a single form and Russian 4 forms.

The 2 forms shown for English in the the workbench:

create demo repository

Single form shown for Japanese:

create demo repository

Four forms shown for Russian:

create demo repository

Android

Corresponding Android resource file (res/values/strings.xml) looks like:

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <!-- Header for the recipe ingredients with the ingredients count section -->
    <plurals name="pin_recipe_ingredients_with_count">
        <item quantity="one">%1$d ingredient</item>
        <item quantity="other">%1$d ingredient</item>
    </plurals>
</resources>

The Japanese resource file (res/values-ja/strings.xml):

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <!-- Header for the recipe ingredients with the ingredients count section -->
    <plurals name="pin_recipe_ingredients_with_count">
        <item quantity="other">材料：%1$d 種類</item>
    </plurals>
</resources>

And the Russian resource file (res/values-ru/strings.xml):

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <!-- Header for the recipe ingredients with the ingredients count section -->
    <plurals name="pin_recipe_ingredients_with_count">
        <item quantity="one">%1$d ингредиент</item>
        <item quantity="few">%1$d ингредиента</item>
        <item quantity="many">%1$d ингредиентов</item>
        <item quantity="other">%1$d ингредиента</item>
    </plurals>
</resources>

Gettext

A corresponding Gettext PO file (messages.pot) would look like:

msgid "%1$d ingredient"
msgid_plural "%1$d ingredient"
msgstr[0] ""
msgstr[1] ""

The Japanese PO file (ja/LC_MESSAGES/messages.po):

msgid "%1$d ingredient"
msgid_plural "%1$d ingredient"
msgstr[0] "材料：%1$d 種類"

And the Russian PO file (ru/LC_MESSAGES/messages.po):

msgid "%1$d ingredient"
msgid_plural "%1$d ingredient"
msgstr[0] "%1$d ингредиент"
msgstr[1] "%1$d ингредиента"
msgstr[2] "%1$d ингредиентов"
