(ComputerCraft) (minecraft version 1.7.10) (question) Make a language file reader

Question

I'd like to make a language reader for my operating system, but I cant find anything that helps me.
I want to put the list into my other script.
Heres the de-de language file (location: /os/bin/):

    de = {
    Menu = "Menü",
    Shutdown = "Ausschalten",
    MenuLength = 4,
    ShutdownLength = 11
    }

Can anyone help me please?

Can you elaborate? You want this list to be put into your other script IF the language `de` is selected? — ConnerWithAnE, Dec 15 '21 at 21:28
Yes, I want to do that, but i want it in different scripts so you can add custom ones — DanielMo09, Dec 16 '21 at 14:21

The gsub() string function/method can do that with your translation table.
You only have to use your language table for that.
Example...

# /usr/bin/lua
Lua 5.3.5  Copyright (C) 1994-2018 Lua.org, PUC-Rio
> de = {
>>     Menu = "Menü",
>>     Shutdown = "Ausschalten",
>>     MenuLength = 4,
>>     ShutdownLength = 11
>>     }
> language = de
> print(('Menu Shutdown'):gsub('(%g+)', language))
Menü Ausschalten    2

If you have to use Lua 5.1 then use %w...

# /bin/lua
Lua 5.1.5  Copyright (C) 1994-2012 Lua.org, PUC-Rio
> de = {
>>     Menu = "Menü",
>>     Shutdown = "Ausschalten",
>>     MenuLength = 4,
>>     ShutdownLength = 11
>>     }
> language = de
> print(('Menu Shutdown'):gsub('(%w+)', language))
Menü Ausschalten    2

The length can be measured with the len() function/method...

> print(('Shutdown'):gsub('(%w+)', language):len())
11
> print(('Menu'):gsub('(%w+)', language):len())
5

As you can see in Lua the Umlaut ü is measured different.

To include your de-de.lua i suggest dofile() that loads it with your specific path...

Lua 5.1.5  Copyright (C) 1994-2012 Lua.org, PUC-Rio
> dofile('/os/bin/de-de.lua') -- But read comment about security
> print(de['Menu'])
Menü

Try to convert the special words with german Umlaut into its byte representation.
And put the bytes into your translation table...

$ lua
Lua 5.4.3  Copyright (C) 1994-2021 Lua.org, PUC-Rio
> print(('Menü'):byte(1,-1))
77  101 110 195 188
> print('\77\101\110\195\188')
Menü
> de = {Menu = '\77\101\110\195\188'}
> print(('Menu'):gsub('%g+', de))
Menü    1

...or for Lua 5.1...

$ /bin/lua
Lua 5.1.5  Copyright (C) 1994-2012 Lua.org, PUC-Rio
> print(('Menü'):byte(1, -1))
77  101 110 195 188
> print('\77\101\110\195\188')
Menü
> de = {Menu = '\77\101\110\195\188'}
> print(('Menu'):gsub('%w+', de))
Menü    1

You also can mix it.
And here are the bytes for: üäößÜÄÖ

> print(('üäößÜÄÖ'):byte(1, -1))
195 188 195 164 195 182 195 159 195 156 195 132 195 150
> de = {Menu = 'Men\195\188', Umlaute = '\195\188\195\164\195\182\195\159\195\156\195\132\195\150'}
> print(('Menu Umlaute'):gsub('%w+', de))
Menü üäößÜÄÖ    2

I got an error: ".temp:1: bios:14: [string "de-de"]:1: unexpected symbol" and also when i try to edit de-de file i get this error: "de = { Menu = window:94: Arguments must be the same length" I tried the print(de['Menu']) test – DanielMo09 Dec 16 '21 at 14:13
For coding I use Visual Studio Code if that helps – DanielMo09 Dec 16 '21 at 14:53
Whats the name of your de file? - ```de-de``` or ```de-de.lua```? – koyaanisqatsi Dec 16 '21 at 15:24
the name is de-de – DanielMo09 Dec 16 '21 at 16:22
i also removed the .lua – DanielMo09 Dec 16 '21 at 16:23
Its very late for me right now BUT I think I just found the problem (I can't try it now because tomorrow is school): I think "ü" is an unicode for ComputerCraft and ComputerCraft doesn't accept unicodes – DanielMo09 Dec 17 '21 at 01:07
You can try the byte representation. Look in my post how to produce byte representation. – koyaanisqatsi Dec 17 '21 at 10:21
It was the Ü and thanks for helping! – DanielMo09 Dec 17 '21 at 13:13

When I recommended `dofile` in another question, I got a few dislikes for "security reasons" :) Alternatively, you can use the Lua deserializer here, which does the same in a more secure way: http://www.computercraft.info/wiki/Textutils.unserialize – Luke100000 Dec 17 '21 at 15:24
Ahh, thanks ima try that too – DanielMo09 Dec 18 '21 at 10:20
