Localisation
============
OpenMW supports localisation of mods using ICU MessageFormat wrapped in YAML.
Currently this is only possible using the
`openmw.core.l10n <../lua-scripting/openmw_core.html##(core).l10n>`_ lua function.
Locales
-------
Locales usually have the form ``{lang}_{COUNTRY}``,
where ``{lang}`` is a lowercase two-letter language code and ``{COUNTRY}`` is an uppercase
two-letter country code. Localisation files *must* have this exact capitalisation and separator
to be recognized.
When users request a locale using the :ref:`preferred locales` setting they do not need to match capitalisation
and can also use hyphens instead of underscores. The locale will be normalised to the above format.
Locales may also contain variants and keywords, though these usually will not be necessary.
See `The Locale chapter of the ICU Guide <https://unicode-org.github.io/icu/userguide/locale/#language-code>`_ for full details.
Localisation Files
--------------------------
Localisation files (containing the message names and translations) should be stored in the
VFS as files of the form ``l10n/<ContextName>/<Locale>.yaml``.
Messages contents have the form of ICU MessageFormat strings.
See `the Formatting Messages chapter of the ICU Guide <https://unicode-org.github.io/icu/userguide/format_parse/messages/>`_
for a guide to MessageFormat, and see
`The ICU APIdoc <https://unicode-org.github.io/icu-docs/apidoc/released/icu4c/classicu_1_1MessageFormat.html>`_
for full details of the MessageFormat syntax.
Examples
~~~~~~~~
.. code-block:: yaml
:caption: DataFiles/l10n/MyMod/en.yaml
good_morning: 'Good morning.'
you_have_arrows: |-
{count, plural,
one {You have one arrow.}
other {You have {count} arrows.}
}
.. code-block:: yaml
:caption: DataFiles/l10n/MyMod/de.yaml
good_morning: "Guten Morgen."
you_have_arrows: |-
{count, plural,
one {Du hast ein Pfeil.}
other {Du hast {count} Pfeile.}
}
"Hello {name}!": "Hallo {name}!"
Select rules can be used to match arbitrary string arguments.
The default keyword ``other`` must always be provided.
.. code-block:: yaml
:caption: DataFiles/l10n/AdvancedExample/en.yaml
pc_must_come: {PCGender, select,
male {He is}
female {She is}
other {They are}
} coming with us.
Numbers have various formatting options and can also be formatted with custom patterns.
See `The ICU Guide <https://unicode-org.github.io/icu/userguide/format_parse/numbers/skeletons.html#syntax>`_
.. code-block:: yaml
:caption: DataFiles/l10n/AdvancedExample2/en.yaml
quest_completion: "The quest is {done, number, percent} complete."
# E.g. "You came in 4th place"
ordinal: "You came in {num, ordinal} place."
# E.g. "There is one thing", "There are one hundred things"
spellout: "There {num, plural, one{is {num, spellout} thing} other{are {num, spellout} things}}."
numbers: "{int} and {double, number, integer} are integers, but {double} is a double"
rounding: "{value, number, :: .00}"
