perl pack equivalent in lua

[baggins]

Thanks admin.

Now, I am developping this script not on LM but on a 'normal' Linux box, because I don't want to use the LM that is in production... Is there some standard lua equivalent for lmcore.hextostring?

Also the perl script converts the command to a readable string for logging purposes:

Code:

$commandhex =~ s/(.)/sprintf("0x%x ",ord($1))/eg;

How would that be done in lua?

Thanks!

I've found a script and written another one that I can use on my Linux box.

Code:

function string.fromhex(str)
    return (str:gsub('..', function (cc)
        return string.char(tonumber(cc, 16))
    end))
end

function printhex (str)
    length = string.len(str)
    result = ""
    for i = 1, length,2 do
        result = result..'0x'..string.sub(str,i,i+1).." "
    end
    return result
end
