C++ Coding Standards Part 0: Automated Code Analysis

Automated analysis is the main advantage to working with a modern statically typed compiled language like C++. Code analysis tools can inform us when we have implemented an operator overload with a non-canonical form, when we should have made a method const, or when the scope of a variable can be reduced.

// ChaiScript has its own simple object model and works well with object
// oriented C++


// There is no difference between a function and a method, it's just syntactic sugar

var s = "mystring".size() // returns 8
var s2 = size("mystring") // returns 8

// class syntax

lefticus

// ChaiScript supports normal functional programming paradigms, with automatic overload resolution

var plus = `+` // get a reference to the function object representing all known `+` functions

print(plus("a", "b")) // prints "ab"
print(plus(1 , 3)) // prints "4"
// print(plus("a" , 3)) // generates a runtime error, no string + int operator available

// Back ticks are only necessary for capturing operator functions

lefticus

// ChaiScript's primary error handling is exceptions, just like C++, and uses C++
// exceptions internally. This means that exceptions can be shared / passed / handled
// between ChaiScript and C++

// catching chaiscript errors inside of chaiscript
try {
  eval("BLARG")
} catch (e) {
  print("Error while processing eval statement"))
}

lefticus

// ChaiScript supports the normal kind of control blocks you've come to expect from 
// C++ and JavaScript
