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

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?

Answer 1

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())

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'])

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
