Edit table data through a directory in lua

Question

I have a table and a directory :

--directory
{
[1] = "File"
[2] = "Documents"
[3] = "txt_Page"
}

--Table for directory
{
Files = {
    File = {
        Documents = {
            txt_Page = "new"
            }
        }
    }
}

I want to edit the txt_page through the directory and return the newly edited files table but I've tried methods and I can't seem to find it.

Answer 1

Just concat it:

tabl = {"File", "Documents", "txt_page"}
path = table.concat(tabl, "/")
print(path)  -- "File/Documents/txt_page"

For Lua table:

local new_txt_Page = 3
local str = "Files['" .. table.concat(tabl, "']['") .. "'] = " .. new_txt_Page
print (str) -- Files['File']['Documents']['txt_Page'] = 3 
load(str)() -- execute the string

If your strings have no spaces dashes etc., then you can make it just like:

str = "Files."..table.concat(tabl, ".").." = ".. new_txt_Page
print (str) -- Files.File.Documents.txt_Page = 3
load(str)()
