Syntax - PatrickDahlin/LuaExe GitHub Wiki
The syntax is currently a (very) limited subset of the math operations that are accessible in lua. This means that the only accepted form of syntax is the following in BNF form:
<statement> := <identifier> = <exp>
<exp> := <var> <binop> <var> | <unop> <var> | ( <exp> )
<var> := NUMBER | <identifier>
<binop> := * | / | + | -
<unop> := -
<identifier> := NAME
