Shell cmd w/ multiple args

I'm trying to expand on to a simple LUA script I wrote (my first time working with LUA) to allow multiple arguments to be passed to it. The problem I'm running into is it seems that the way I'm doing it gives one argument regardless of what I type (I ran into a similar problem when first writing it where the argument wouldn't be nil when nothing was passed to it).

Here's my script:

Code:

import "Turbine"



AhCmd = Turbine.ShellCommand();



function AhCmd:Execute(cmd, arg1, arg2)

        if ( type(tonumber(arg1)) == "number"  and  arg2 == nil ) then

                AhCmd:AhCalc(arg1);

        elseif ( type(tonumber(arg1)) == "number" and type(tonumber(arg2)) == "number" ) then

                AhCmd:AhCalc(arg1, arg2);

        else

                AhCmd:GetHelp();

        end

end



function AhCmd:AhCalc(buyout, bid)

        if (bid == nil) then

                Turbine.Shell.WriteLine( "<rgb=#00FF00>Set Buyout to</rgb> <rgb=#FFFF00>" .. math.floor( ( buyout/0.95)*(10^2) )/(10^2) .. "s</rgb> <rgb=#00FF00>to get</rgb> <rgb=#80FF00>" .. buyout .. "s</rgb>" );

        else

                Turbine.Shell.WriteLine( "<rgb=#00FF00>Set Starting Bid to</rgb> <rgb=#FFBF00>" .. math.floor( ( bid/0.95)*(10^2) )/(10^2) .. "s</rgb><rgb=#00FF00>, Buyout to</rgb> <rgb=#FFFF00>" .. math.floor( ( buyout/0.95)*(10^2) )/(10^2) .. "s</rgb> <rgb=#00FF00>to get between</rgb> <rgb=#80FF00>" .. bid .. "s</rgb> <rgb=#00FF00>and</rgb> <rgb=#80FF00>" .. buyout .. "s</rgb>" );

        end

end



function AhCmd:GetHelp()

        Turbine.Shell.WriteLine( "Syntax: /ah <price>" );

end



Turbine.Shell.AddCommand( "ah", AhCmd );

The script accurately acknowledges 1 argument, but will just return the help text if 2 are is sent.
I know could just add a 2nd command specifically written to accept 2 args, but I really want just 1 command to work for everything

Hi MuNkEy,

if I recall correctly, than there is only one argument passed to Execute:

Code:

Execute = function(sender, cmd, args)

I.e. args is one big string holding all the parameters. Therefore you may want to parse args in a loop and find all your parameters.

Just an update in case it helps anyone in the future...

I solved this by adding the split function

Code:

function split(pString, pPattern)

        local Table = {} -- NOTE: use {n = 0} in Lua-5.0

        local fpat = "(.-)" .. pPattern

        local last_end = 1

        local s, e, cap = pString:find(fpat, 1)

        while s do

                if s ~= 1 or cap ~= "" then

                        table.insert(Table,cap)

                end

                last_end = e+1

                s, e, cap = pString:find(fpat, last_end)

        end

        if last_end <= #pString then

                cap = pString:sub(last_end)

                table.insert(Table, cap)

        end

        return Table

end

once you have that function, you can split the string to an array with

Code:

function Execute(cmd, args)

        args = split(args, " ");

end

you can also easily implement string.split using string.gmatch:

Code:

string.split=function(str,separator)

local tmpArray={};

local tmpElem;

 if string.find("^$()%.[]*+-?",separator,1,true)~=nil then separator="%"..separator end

 for tmpElem in string.gmatch(str,"[^"..separator.."]+") do

  table.insert(tmpArray,tmpElem);

 end

 return tmpArray;

end

then use the same as your original split function:

Code:

args = string.split(args, " ");

This version also allows using control characters, including "%" as separators.

EDIT: After playing with it a bit, I realized that the simple solution I originally posted doesn't account for "empty" values between separator characters and neither the original nor the simple version accounted for empty values at the end of the string. So, a more complete (but slightly uglier) version is:

Code:

string.split=function(str,separator)

 local tmpArray={};

 local tmpElem;

 str=tostring(str);

 if string.find("^$()%.[]*+-?",separator,1,true)~=nil then separator="%"..separator end

 for tmpElem in string.gmatch(str,"[^"..separator.."]*") do

  table.insert(tmpArray,tmpElem);

 end

 local tmpIndex=1;

 while tmpIndex<=#tmpArray do

  if tmpIndex==#tmpArray and tmpArray[tmpIndex]=="" then

  table.remove(tmpArray,tmpIndex);

  else

  if tmpArray[tmpIndex]=="" and tmpArray[tmpIndex+1]~="" then

    table.remove(tmpArray,tmpIndex);

  else

    tmpIndex=tmpIndex+1;

  end

  end

 end

 return tmpArray;

end
