   |   INI File Reading and WritingHello, I am having trouble finding a lua based INI reader/writer. I need it all done via LUA, which means the use of io.open ect. Does anyone have, know wher to get, or can build one for me. I would greatly appreciate it. I do have one that works a little.. but it is Extremely buggy: Code: function WriteINI(File, Section, KeyName, Value)-- Installation:
 --   1: Place this function at the end of your luaplugin.lua
 --   2: Example code >  WriteINI("ssgm.ini", "Plugins", "01", "LuaPlugin.dll")
 --       This would write ssgm.ini, in the [Plugins] Section and change "01" keyname
 --   3: Example Code 2 >  WriteINI("LuaPlugins/readini.ini", "Source", "Keyname", "Value")
 --       This would read from the LuaPlugins Directory.
 
 
 -- Here are the errors that are returned if you wish to change them.
 
 ArgError = "None"    -- Passed invalid arguments to function
 
 blnSection = false
 intAction = 0
 strBracket = [[[]]
 strCloseBracket = [[].]]
 strCloseBracket = string.sub(strCloseBracket, 1, 1)
 Save = ""
 
 if File ~= nil and Section ~= nil and KeyName ~= nil and Value ~= nil then
 if File ~= "" and Section ~= "" and KeyName ~= "" and Value ~= "" then
 i = io.open(File, "r")
 if i ~= nil then
 while true do
 local Line = i:read()   -- Reads a line
 if Line == nil then
 break
 else
 if intAction == 0 then
 if blnSection == false then
 Found = string.sub(Line, 0, 1)
 if Found == strBracket then -- Found Header
 Header = string.sub(Line, 2, -2)
 if Header == Section then
 blnSection = true
 end
 end
 else
 Header = string.sub(Line, 0, 1)
 if Header == strBracket then
 Line = KeyName .. "=" .. Value .. "\n" .. Line
 intAction = 1
 elseif Header == ";" then
 -- Ignor Comments
 elseif Line == "" then
 -- Ignor Blank Lines
 else
 strFindEqual = string.find(Line, "=")
 if strFindEqual ~= nil then
 strKeyname = string.sub(Line, 0, strFindEqual - 1)
 if strKeyname == KeyName then
 Line = KeyName .. "=" .. Value
 intAction = 1
 end
 end
 end
 end
 end
 
 Save = Save .. Line .. "\n"
 end
 end
 
 i:close()
 
 if intAction == 1 then
 --
 else
 Save = Save .. strBracket .. Section .. strCloseBracket .. "\n" .. KeyName .. "=" .. Value
 end
 
 i = io.open(File, "w")
 i:write(Save)
 i:close()
 else
 i = io.open(File, "w")
 i:write(strBracket .. Section .. strCloseBracket .. "\n" .. KeyName .. "=" .. Value)
 i:close()
 end
 else
 return ArgError
 end
 else
 return ArgError
 end
 end
 
 function ReadINI(File, Section, KeyName)
 -- Installation:
 --   1: Place this function at the end of your luaplugin.lua
 --   2: Example code >  Read = ReadINI("ssgm.ini", "Plugins", "01")
 --       This would read ssgm.ini, in the [Plugins] Section, And most likly will return LuaPlugin.dll
 --   3: Example Code 2 >  Read = ReadINI("LuaPlugins/readini.ini", "Source", "Keyname")
 --       This would read from the LuaPlugins Directory.
 
 -- By Default this function will return "None" if nothing is found, And "NoFile" if the file you are trying
 -- to read does not exist.
 
 -- Here are the errors that are returned if you wish to change them.
 
 NoneError = "None"    -- Didnt Find Keyname in file
 FileError = "NoFile"    -- No file exists
 ArgError = "None"    -- Passed invalid arguments to function
 
 blnSection = false
 intAction = 0
 strBracket = [[[]]
 
 if File ~= nil and Section ~= nil and KeyName ~= nil then
 if File ~= "" and Section ~= "" and KeyName ~= "" then
 i = io.open(File, "r")
 if i ~= nil then
 while true do
 local Line = i:read()   -- Reads a line
 if Line == nil or intAction ~= 0 then
 break

 strKeyname = string.sub(Line, 0, strFindEqual - 1)
 if strKeyname == KeyName then
 intAction = 1
 Value = string.sub(Line, strFindEqual + 1)
 end
 end
 end
 end
 end
 end
 
 i:close()
 
 if intAction == 1 then
 return Value
 elseif intAction == 2 then
 return NoneError

 return NoneError

 return FileError

   |   Re: INI File Reading and WritingThe CC engine's lua implementation cannot do I/O anyways.
 Unless you want to make an external reader (debugger?) and for some godforsaken reason want to do it in Lua I really can't see why you're doing this.

   |   Re: INI File Reading and WritingIt is very hard to find any forum or community that does LUA scripting at all.I did not know your community's use of LUA did not include IO operations.
 It should though since LUA v5 supports it.
 
 But thanks for your help.

   |   Re: INI File Reading and WritingCC's Lua implementation is... lacking at best. Hopefully Data will make it better in future versions, but so far this is not the case.

   |   Re: INI File Reading and WritingOur community at DCOM Productions  has implemented LUA into the game Command and Conquer: Renegade  vastly. It is open source, and created by a total pro who knows his stuff. You should check it out, you may be able to learn something from it.Our LUA forums. We don't support CC, though, But we may be able to help with lua implementation. Thanks for all your help.

   |   Re: INI File Reading and WritingHey uh halotupac or whatever the ♥♥♥♥
 you're sounding more and more like a spambot
 
 I/O is not included with CC's lua on purpose so that people can't write a program to do dumb ♥♥♥♥
 
 also considering that lua project that you guys did you sure are unclear on how to actually type lua

Included libaries, IRClands style. That said, file I/O should be allowed to the CC folder, imho.

   |   Re: INI File Reading and WritingWith that and other things as exceptions. Anyway, I'm sure a key stealing mod will result in a ban.
 As I said, file libs.
