how do I define c style code blocks in lua?

Question

is there a way to define {} and blankspace as a lua code block?

something like this..

function()
{
   local x = 3
   if     (x == 1) { print("hi1") }
   elseif (x == 2)   print("hi2") 
   else   (x == 3)   print("hi3") 
}

it would also be nice to define things like ++ and += too

Answer 1

Just use do..end . += operator and friends aren't conformant with spirit of Lua. Your code will not run. First of all, you need to understand basic Lua syntax. Example of corrected code:

function f()
   local x = 3
   if x == 1 then
      print("hi1")
   elseif x == 2 then
      print("hi2")
   elseif x == 3 then
      print("hi3")
   end
end

To create block simply use

do
  print('Hello, world!')
end
