Re: [Q] simple translator from Lua to Java Script and PHP

["V S P" <toreason@...>]

Sure,
here it is (there are two files and a test file)

http://pastebin.com/f6dbea82b

----  lua file like this

if arr1.field1<arr2.field1  or arr1.field2>arr2[33][15] then
  call_func2("xyz")
elseif a<b then
  call_func3("abc")
  call_func4("abc")
else
  call_func5(123)
end


-----------



will get translated into 
-------------

if( js_iop_or( js_iop_lt( arr1['field1'], arr2['field1'])
, js_iop_lt( arr2[33][15], arr1['field2'])
)
)
{
 call_func2('xyz') ;
}
else if
( js_iop_lt(a,b)
)
{
 call_func3('abc') ; call_func4('abc') ;
}
else

{
 call_func5(123) ;
}/*end of if*/

-------------

I also have many call backs
context sensitive callbacks and 'output language builder' callbacks
(to translate to other languages if I need to)

I just have it serving my needs because it does not do
even assignment operations (because I use function calls for assignments
and does not support parenthesis, of course nothing like function
declarations either....


I can add some things easily , but others are obviously way beyound
my skills.

Also, I have been programming Lua just for two months, so my code
may be 'cheesy' to many hardcore people

Well -- done with disclaimers :-)
