在 Lua 中打开以日语命名的文件

Question

我有一堆 XML 文件用日文命名。我使用 Lua 来阅读它们并将必要的信息放入表格中。我可以打开仅以单个汉字命名的文件，如名。xml，但对于多个汉字，如名前。xml，这是相反的。在运行 Lua 文件之前，我将命令行的代码页设置为 65001（作为 UTF-8）。要读取文件，我需要使用 WinAPI 库将文件名从 ACP（ASCII 代码页？）编码为 UTF-8，但这种编码仅适用于单个汉字。我已经在 Internet 上尝试了一些建议，使用文件的短路径等，但其中 none 行得通。我试图通过运行 Lua 作为管理员使用短路径——如其他类似问题所述，您需要管理员权限才能使用短路径——但没有成功。

...
for fn in io.popen("DIR xml /B /AA"):lines() do
    ...
    local f = assert(io.open("xml\" .. winapi.encode(winapi.CP_UTF8, winapi.CP_ACP, fn), "rb"))
    ...
end
...

但是我的代码产生了 "Invalid argument" 错误。我搜索了这个错误，但其中 none 个是 Lua 相关的，所以我打开了 C/C++ 相关的，但我得到的只是 'use _wfopen' 之类的那。它没有在 Lua 中实现，我也不想自己实现它。所以有人知道如何解决这个问题吗？如需更多信息，请务必让我知道。谢谢！

Answer 1

我不知道为什么您的程序无法运行，但请尝试以下解决方法：

local pipe = io.popen([[for %G in (xml\*) do @(type "%G" & echo @FILENAMEMARKER#%G)]], "rb")
local all_files = pipe:read"*a"
pipe:close()
for filecontent, filename in all_files:gmatch"(.-)@FILENAMEMARKER#(.-)\r?\n" do
   -- process your file here
   print('===== This is your file name:')
   print(filename)
   print('== This is your file content:')
   print(filecontent)
   print('== End of file')
end

我认为你可以在 table 中使用日文字母

local jaAlphbet={"一","｜","丶","ノ","乙","亅","<","二","亠","人","⺅","","儿","入","ハ","丷","冂","冖","冫","几","凵","刀","⺉","力","勹","匕","匚","十","卜","卩","厂","厶","又","マ","九","ユ","乃","","⻌","口","囗","土","士","夂","夕","大","女","子","宀","寸","小","⺌","尢","尸","屮","山","川","巛","工","已","巾","干","幺","广","廴,"廾","弋","弓","ヨ","彑","彡","彳","⺖","⺘","⺡","⺨","⺾","⻏","⻖","也","亡","及","久","⺹","心","戈","戸","手","支","攵","文","斗","斤","方","无","日","曰","月","木","欠","止","歹","殳","比","毛","氏","气","水","火","⺣","爪","父","爻","爿","片","牛","犬","⺭","王","元","井","勿","尤","五","屯","巴","毋","玄","瓦","甘","生","用","田","疋","疒","癶","白","皮","皿","目","矛","矢","石","示","禸","禾","穴","立","⻂","世","巨","冊","母","⺲","牙","瓜","竹","米","糸","缶","羊","羽","而","耒","耳","聿","肉","自","至","臼","舌","舟","艮","色","虍","虫","血","行","衣","西","臣","見","角","言","谷","豆","豕","豸","貝","赤","走","足","身","車","辛","辰","酉","釆","里","舛","麦","金","長","門","隶","隹","雨","青","非","奄","岡","免","斉","面","革","韭","音","頁","風","飛","食","首","香","品","馬","骨","高","髟","鬥","鬯","鬲","鬼","竜","韋","魚","鳥","鹵","鹿","麻","亀","啇","黄","黒","黍","黹","無","歯","黽","鼎","鼓","鼠","鼻","齊","龠"}
print(jaAlphbet[1])--and you can call the letters, letter by letter
