Hi. I'm now digging in some chinese program and want to create some directory paths.
Everything is working as intended, I can create files with chinese name.
But when it comes to creating folder with chinese chars in it's name - I'm totally stuck.

I'm using windows "mkdir" command with the full and correct path

Code: Select all

Destination = "C:\\Some\\Folders\\格力2-ABC\\"
os.execute("mkdir \""..Destination.."\"")

os.execute is returning "true" and path is created indeed . But all chinese symbols are messed up and this leads to creating path
"C:\Some\Folders\ж јеЉ›2-ABC" and now "writeRegionToFile" cant find "Destination" folder.

I tried using "lfs.mkdir" command, but seems that it uses the same method as previous and path is messed up in the same way.

So I want to create folder with correct name, or at least just check if folder is created correctly. Is it somehow possible without sanitizing "Destination" string?

This is because Lua is ANSI C based and Chinese characters are unicode. You will need an external library to handle such strings which you can find at [Link]. At least that's the only way I know of. If someone else knows a better way that I am more than welcome to listen

But it's more over-engineered than just checking path to contain only english letters, numbers and symbols.
Anyway, Thanks, I'll look into it - library seems very useful at first glance.

It is a useful library that contains a lot of Windows-specific things that you may find useful.

^ you should also check this out: [ [Link] ]. This library is integrated in CE (using it myself in my tables), but "obviously" i'm not aware if it supports multi_char sets (no mentioning @ github).
If it does, please report back.

As I said in the topic - lfs.mkdir not helped - it created the same dir as native windows "mkdir".
And with default settings - generated trainers does not include it.

Also, I just found in celua one useful thing called "ansiToUtf8(string)" - thanks LeFiXER for mentioning ANSI.
So I can just use

Code: Select all

if ansiToUtf8(FilePath) ~= FilePath then print("Failed.") end

To see, if path will be broken and use exe's root dir instead.

Yup, I think it's better to include one library to bypass all the problems I can encounter in the future. Thanks again!
Now I just need to figure out, how to compile it and include in the CT and EXE(As I think - include it in cheat table lua script and then add in exe's "extra files") . Never did that before.

Nwm, figured it out, but still without 32bit version

Well, seems that I just can't compile "winapi" library - tried gcc, msvc, even luarocks.
Only gcc succeeded - but when it comes to loading dll with CE - it throws an error like

Code: Select all

main.lua error:error loading module "winapi" from file
"C:\ProgramFiles\CheatEngine 7.2\winapi.dll": ?? ?????? ????????? ??????.

Or last part is changing to "%1 ?? ???????? ??????????? Win32" if I'm trying to load it with 32bit CE - because I cant compile dll with 32bit lua5.1.dll
I'm sorry for the dumb question, but can someone send me working dll? I can't find any.[/i]

Well, just used "lua53-64.dll" and it's headers from Cheat Engine folder, as Dark Byte said [Link].
Now library loads and it's commands are executed correctly.
But anyway - winapi.make_dir() is creating folder with the same broken name. So, full day spent for nothing.

Use winapi.short_path()

May try this. The function should be able to make for other usage, eg. rmdir etc.

Code: Select all

function cmd_utf8(cmd_tmplate, debugCheck)
  return function(...)-- string parameter to be put in template
    local tmp, fms = os.getenv'TEMP', string.format
    local name = os.tmpname():match[[([^\]*)$]]
    local cmd = fms([[%s\%s.cmd]],tmp,name)
    if debugCheck then print('path:',cmd)end-- for debug
    -- sending utf txt by a cmd file instead via command-line
    -- chcp 65001 -> utf8 encoding
    local cmdtxt = fms([[
    @echo off
    chcp 65001
    ]]..cmd_tmplate, ... )--  string params from input, each %s in template should match count of ... (varargs)
    if debugCheck then print('cmd--\n',cmdtxt,'\n--') end
    local f = io.open(cmd,'wb')
    if not f then return nil,'fail open cmd'else
      local ok = f:write(cmdtxt),f:close()
      if not ok then return nil,'fail write cmd'else
        shellExecute('cmd',fms('/c call "%s" && del /Q "%s"',cmd, cmd),nil,false)
        return true
      end
    end
  end
end
-- test
local mkdir_utf8 = cmd_utf8([[
    mkdir "%s"
 ]],true)--<-- remove true for no debug print
mkdir_utf8[[d:\00exe\逆転裁判]]-- it may need to be a full path, for it executed from a cmd at temp dir.

I tried, but it does not create folders, only files in existing folders

Code: Select all

testfolder = winapi.short_path("testfolder\\testfile")
testfile = winapi.short_path("testfile")

print(tostring(testfolder))
print(testfile)

nil 
testfile

Maybe I just don't understand something, but api's example file "testshort.lua" does not create folders too.

Many thanks, sir panraven, you're always a savior.
Firstly I tried creating a pipe to cmd and then passing commands, but it didn't helped.
Then I thought about creating batch file with mkdir and path string, but stuck at the moment of writing to file the string I wanted. Totally forgot about lua's io.open.
Your code is working great, even does not blink with unnecessary CMD window. But for me - sometimes it does not delete cmd file if command is executed repeatedly, and with random names - there's a bunch of old cmd's left in temp folder. Not a big deal - I can just hardcode file name.
