清单的本地化 [英] Localization of lists

问题描述

对字符串列表进行本地化的正确方法是什么?我知道分隔符可以被本地化为逗号或分号，但是连词是否被本地化了?如果是这样，我的任意长度列表的格式字符串将是什么样?

What is the right way to localize a list of strings? I know that the separator can be localized to a comma or a semi-colon but does the conjunction get localized? If so, what would my format string for an arbitrary length list look like?

示例

蝙蝠，猫和狗".我可以按区域设置使用分隔符，并按以下方式构造LIST:

"Bat, Cat and Dog". I could use the separator as per locale and construct the LIST as the following:

LIST := UNIT
LISTMID := UNIT SEPARATOR UNIT
LISTMID := LISTMID SEPARATOR UNIT
LIST := UNIT CONJUNCTION UNIT
LIST := LISTMID CONJUNCTION UNIT

我是否必须根据每种语言制定此规则?有没有可用的库来帮助解决这个问题?

Would I have to craft this rule per language? Any libraries available to help with this?

推荐答案

我来到这里寻找相同问题的答案，并最终进行了更多的谷歌搜索，结果发现:

I came here looking for an answer to the same question, and ended up doing more googling, which found this: http://icu-project.org/apiref/icu4j/com/ibm/icu/text/ListFormatter.html

该类采用参数two，start，middle和end:

• two-两个项目的字符串，第一个包含{0}，第二个包含{1}.
• start-列表项开始的字符串，第一个包含{0}，其余包含{1}.
• middle-列表项开头的字符串，其中，列表的第一部分包含{0}，列表的其余部分包含{1}.
• end-列表项末尾的字符串，其中，列表的第一部分为{0}，最后一项为{1}.

因此，对于英语来说，应该是:

So, for English, that would be:

 - TWO := "{0} and {1}"
 - START := "{0}, {1}"
 - MIDDLE := "{0}, {1}" 
 - END := "{0} and {1}"

我写了一个简短的Lua演示来说明我的工作原理:

I wrote a quick Lua demonstration for how I imagine this works:

function list_format(words, templates)
    local length = #words
    if length == 1 then return words[1] end
    if length == 2 then 
        return replace(replace(templates['two'], '{0}', words[1]), 
            '{1}', words[2])
    end

    local result = replace(templates['end'], '{1}', words[length])
    while length > 3 do
        length = length - 1
        local mid = replace(templates['middle'], '{1}', words[length])
        result = replace(result, '{0}', mid)
    end
    result = replace(result, '{0}', words[2])
    result = replace(templates['start'], '{1}', result)
    result = replace(result, '{0}', words[1])
    return result
end

function replace(template, index, text)
    str, _ = string.gsub(template, index, text)
    return str
end

local english = {
    ["two"] = "{0} and {1}",
    ["start"] = "{0}, {1}",
    ["middle"] = "{0}, {1}",
    ["end"] = "{0} and {1}"
}

print(list_format({"banana"}, english))
print(list_format({"banana", "apple"}, english))
print(list_format({"banana", "apple", "mango"}, english))
print(list_format({"banana", "apple", "mango", "pineapple"}, english))

要使其适应其他语言应该是微不足道的.

It should be trivial to adapt this for other languages.
