-- Sample configuration for languages to support

-- The languages table contains a table per language to support.
-- The keys are the language code used by OpenStreetMap, e.g. "en" for English.
-- The values are tables. Use empty tables if you want the value of name:xx=*
-- to be written to the attribute name_xx. Use a table with a key "fallback"
-- if you want to provide an array of fallback keys. They will be read in the
-- provided order.
--
-- Fallback keys must
-- be provided as full OSM keys ("name:xx", not "xx"). You can access any tag here,
-- e.g. official_name:xx=* as a fallback if name:xx=* is not set and you wish to have
-- as much localised names as possible in your vectortiles even if they are outdated.
local languages = {
	-- Add English (en). This will write the value of name:en
	-- to the attribute name_en. If no name:en=* is set, Tilemaker will
	-- try name:de=*, name:fr=*, int_name=* and name=* in the given order as fallbacks.
	en = {
		fallback = { "name:de", "name:fr", "int_name", "name" },
	},
	-- Add German (de) using name:en, name:fr, int_name and name as fallbacks.
	de = {
		fallback = { "name:en", "name:fr", "int_name", "name" },
	},
	-- Add Russian without any fallback. If an OSM object has no name:ru,
	-- no name_ru attribute will be written.
	ru = {
		fallback = { },
	},
	-- Add Ukrainian without any fallback (alternative notation).
	uk = { },
	-- Note: You can't set a value to nil. Lua will skip this entry.
	-- Following line will cause Esperanto to be ignored.
	eo = nil,
}

-- Do not remove return statement.
