Hi,

Here is the code for loading and saving tables converted to LUA 5.0...

function Serialize(tTable, sTableName, sTab)
        assert(tTable, "tTable equals nil");
        assert(sTableName, "sTableName equals nil");

        assert(type(tTable) == "table", "tTable must be a table!");
        assert(type(sTableName) == "string", "sTableName must be a string!");

        sTab = sTab or "";
        sTmp = ""

        sTmp = sTmp..sTab..sTableName.." = {\n"

        for key, value in tTable do
                local sKey = (type(key) == "string") and string.format("[%q]",key) or string.format("[%d]",key);

                if(type(value) == "table") then
                        sTmp = sTmp..Serialize(value, sKey, sTab.."\t");
                else
                        local sValue = (type(value) == "string") and string.format("%q",value) or tostring(value);
                        sTmp = sTmp..sTab.."\t"..sKey.." = "..sValue
                end

                sTmp = sTmp..",\n"
        end

        sTmp = sTmp..sTab.."}"
        return sTmp
end

function SaveToFile(file , table , tablename)
local handle = io.open(file,"w+")
        handle:write(Serialize(table, tablename))
handle:flush()
        handle:close()
end

function LoadFromFile(file)
local handle = io.open(file,"r")
        if (handle ~= nil) then
                loadstring(handle:read("*all"))
handle:flush()
handle:close()
        end
end

Along the same lines, this just is just a bit of IO to store some text in a log file. :)

filename = "../logs/nuked.log";

function StoreFlooder(curUser, sFloodUser)
data = sFloodUser.." was flooded by "..curUser.. " on "..os.date("%d").."."..os.date("%m").."."..os.date("%y").." at "..os.date("%H")..":"..os.date("%M")..":"..os.date("%S").."\r\n";
local file = io.open( filename, "a" );
file:write( data );
file:close();
return 1;
end
This expects 2 usernames as input, but is easy to change to suit your needs.  No prizes for guessing which script i put this in, but i won't post the rest of the script, because the origial author (Phatty) removed the LUA 4 version cause of abuse.  I agree with and respect his decision. :)

Hi,

Made a little update in the code above.

Best regards, nErBoS

this is a bit more open way, so you can use it for several log files.
function StoreLog(file, msg)
local fFile = io.open( file, "a" );
fFile:write( msg);
fFile:close();
return 1;
end

StoreLog("../logs/nuked.log", sFloodUser.." was flooded by "..curUser.. " on "..os.date("%d").."."..os.date("%m").."."..os.date("%y").." at "..os.date("%H")..":"..os.date("%M")..":"..os.date("%S").."\r\n")

Thanks Plop. :)
That looks a lot neater as well as being more versitile. :)

Good job nErBoS and plop!  :D

As i haven't looked into lua5 too much, i appreciate this howto very much. But one question: in lua5 you first create the whole string to write, then, and only then you write it, don't you?

Hi,

If i have understood your question well.... no you can write whatever you want using the write(string) until you close the file, you can call the times you want the write(string), it will start write in the point that it last wrote, like in LUA 4.

Best regards, nErBoS

here's another one for Lua 5 ..

for loading just use dofile("file.lua")

--================================================================---
--==-- Save file/table Functions ================================---
--================================================================---

Save_Serialize = function(tTable, sTableName, hFile, sTab)
sTab = sTab or "";
hFile:write(sTab..sTableName.." = {\n" );
for key, value in tTable do
local sKey = (type(key) == "string") and string.format("[%q]",key) or string.format("[%d]",key);
if(type(value) == "table") then
Save_Serialize(value, sKey, hFile, sTab.."\t");
else
local sValue = (type(value) == "string") and string.format("%q",value) or tostring(value);
hFile:write( sTab.."\t"..sKey.." = "..sValue);
end
hFile:write( ",\n");
end
hFile:write( sTab.."}");
end

Save_File = function(file,table , tablename )
local hFile = io.open (file , "w")
Save_Serialize(table, tablename, hFile);
hFile:close()
end

Typhoon?

i have a question it possible to make a table in table

nested tables are possible and can go as deep as you have memory.

Way depends on how you wanna use, will it be a table like

table={"a","b","c"}

(a. k. a. array)

or like

table={["a"]=1,["b"]=2}

?

Anyway, example for both:

function ReadFile(file)
 local table={} -- create table
 local f=io.open(file,"r") -- open the file for reading
 if f then -- if file exists
  for line in f:lines() do -- parse lines in file one by one
   table.tinsert(line) -- insert every line
   -- OR:
   --table[line]=1 --useful if you wanna dfo hashing later
  end
 end
end

function ReadFile(file) -- another way, for file like: a|b (separator can be custom of course)
 local table={} -- create table
 local f=io.open(file,"r") -- open the file for reading
 if f then -- if file exists
  for line in f:lines() do -- parse lines in file one by one
   local _,_,k,v=string.find(line,"(.+)|(.+)")
   table[k]=v
  end
 end
end


function SaveFile(table,file)
 local f=io.open(file,"w+") -- open the file for writing
 if f then -- this is always true imho
  for key,value in table do -- ok, now parse the table contents one by one
   f:write(key) -- and write them to file
   --OR
   -- f:write(key.."|"..value) -- it outputs: a|b (see above)
  end
 end
end
Sorry, edited under linux with kedit, no debugging or highlighting was possible, but hope this will help. :)

No syntax errors in my post, found SciTE (http://www.scintilla.org/SciTE.html). :))

bastya_elvtars 10x for answer , but pls be more specific

Quotetable1 have
usr.nick
usr.sher
usr.connect

nick="nick",
share=11654310242B
connect=1
}

-- however there is still user.bConnected... :)
Not a so hard-to-save string. :P

i whant to make something like this
user={
      nick="nick",
      share=11654310242B,
      connect={ [1]="os.date"%h:%m"",
                        [2]="os.date"%h:%m"",
......................................................................
                        [n]="os.date"%h:%m"",

Eh, eh. When I release LawMaker, we can go back to this, now I have no time.

ok 10x i will wait  a sollution to my problem

check my freshstuff or texter bot's (latest versions).
think you'll find some nice hints/info there.
