INI File Reading and Writing
Hello, 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 else 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 intAction = 2 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 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 else return NoneError end else return FileError end else return ArgError end else return ArgError end end

Re: INI File Reading and Writing
The 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 Writing
It 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 Writing
CC'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 Writing
Our 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 Writing
Hey 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 Writing
With that and other things as exceptions. Anyway, I'm sure a key stealing mod will result in a ban.
As I said, file libs.
