+# Contributing to ChaiScript
+
+Thank you for contributing!
+
+# Pull Requests
+
+Please follow the existing style in the code you are patching.
+
+ - two space indent
+ - no tabs EVER
+ - match the existing indentation level
+ 
+All ChaiScript commits are run through a large set of builds and analysis on all supported platforms. Those results are posted on the 
+[build dashboard](http://chaiscript.com/ChaiScript-BuildResults/index.html). No PR will be accepted until all tests pass.
+
+The build system has full integration with GitHub and you will be notified automatically if all tests have passed.
+
+# Issues
+
+Please do not post a "chaiscript is too slow", "chaiscript compiles too slowly", or "chaiscript needs more documentation" issue
+without first reading the following notes.
+
+## ChaiScript is Too Slow
+
+We are actively working on constently improving the runtime performance of ChaiScript. With the performance being
+[monitored with each commit](http://chaiscript.com/ChaiScript-BuildResults/performance.html).
+
+If you feel you *must* post an issue about performance, please post a complete example that illustrates the exact case you
+feel should be better optimized.
+
+Any issue request regarding performance without a complete example of the issue experienced will be closed.
+
+## ChaiScript Compiles Too Slowly
+
+This is also something we are actively working on. If you need highly optimized build times, please see [this discussion
+on the discourse site](http://discourse.chaiscript.com/t/slow-build-times/94).
+
+## ChaiScript Needs More Documentation
+
+If you have a question that is not addressed in the [cheatsheet](https://github.com/ChaiScript/ChaiScript/blob/develop/cheatsheet.md) 
+please open an issue so we can get the Cheatsheet updated.

+# ChaiScript Versioning
+
+ChaiScript tries to follow the [Semantic Versioning](http://semver.org/) scheme. This basically means:
+
+  * Major Version Number: API changes / breaking changes
+  * Minor Version Number: New Features
+  * Patch Version Number: Minor changes / enhancements
+  
+
+
+# Initializing ChaiScript
+
+```
+chaiscript::ChaiScript chai; // loads stdlib from loadable module on file system
+chaiscript::ChaiScript chai(chaiscript::Std_Lib::library()); // compiles in stdlib
+```
+
+# Adding Things To The Engine
+
+## Adding a Function / Method / Member
+
+### General
+
+```
+chai.add(chaiscript::fun(&function_name), "function_name");
+chai.add(chaiscript::fun(&Class::method_name), "method_name");
+chai.add(chaiscript::fun(&Class::member_name), "member_name");
+```
+
+### With Overloads 
+
+#### Preferred
+
+```
+chai.add(chaiscript::fun<ReturnType (ParamType1, ParamType2)>(&function_with_overloads), "function_name");
+```
+
+#### Alternative
+
+```
+chai.add(chaiscript::fun(std::static_cast<ReturnType (*)(ParamType1, ParamType2)>(&function_with_overloads)), "function_name");
+```
+This overload technique is also used when exposing base member using derived type
+
+```
+struct Base
+{
+  int data;
+};
+
+struct Derived : public Base
+{};
+
+chai.add(chaiscript::fun(static_cast<int(Derived::*)>(&Derived::data)), "data");
+```
+
+### Lambda
+
+```
+chai.add(
+  chaiscript::fun<std::string (bool)>(
+    [](bool type) { 
+      if (type) { return "x"; } 
+      else { return "y"; } 
+    }), "function_name");
+```
+
+### Constructors
+
+```
+chai.add(chaiscript::constructor<MyType ()>(), "MyType");
+chai.add(chaiscript::constructor<MyType (const MyType &)>(), "MyType");
+```
+
+## Adding Types
+
+It's not strictly necessary to add types, but it helps with many things. Cloning, better errors, etc.
+
+```
+chai.add(chaiscript::user_type<MyClass>(), "MyClass");
+```
+
+## Adding Type Conversions
+
+User defined type conversions are possible, defined in either script or in C++.
+
+A helper function exists for strongly typed and ChaiScript `Vector` function conversion definition:
+
+```
+chai.add(chaiscript::vector_conversion<std::vector<int>>());
+```
+
+A helper function also exists for strongly typed and ChaiScript `Map` function conversion definition:
+
+```
+chai.add(chaiscript::map_conversion<std::map<std::string, int>>());
+```
+
+
+This allows you to pass a ChaiScript function to a function requiring `std::vector<int>`
+
+## Adding Objects
+
+```
+chai.add(chaiscript::var(somevar), "somevar"); // copied in
+chai.add(chaiscript::var(std::ref(somevar), "somevar"); // by reference, shared between C++ and chai
+auto shareddouble = std::make_shared<double>(4.3);
+chai.add(chaiscript::var(shareddouble), "shareddouble"); // by shared_ptr, shared between c++ and chai
+chai.add(chaiscript::const_var(somevar), "somevar"); // copied in and made const
+chai.add_global_const(chaiscript::const_var(somevar), "somevar"); // global const. Throws if value is non-const, throws if object exists
+chai.add_global(chaiscript::var(somevar), "somevar"); // global non-const, throws if object exists
+chai.set_global(chaiscript::var(somevar), "somevar"); // global non-const, overwrites existing object
+```
+# Using STL
+ChaiScript recognize many types from STL, but you have to add specific instantiation yourself.
+
+```
+typedef std::vector<std::pair<int, std::string>> data_list;
+data_list my_list{ make_pair(0, "Hello"), make_pair(1, "World") };
+chai.add(chaiscript::bootstrap::standard_library::vector_type<data_list>("DataList"));
+chai.add(chaiscript::bootstrap::standard_library::pair_type<data_list::value_type>("DataElement"));
+chai.add(chaiscript::var(&my_list), "data_list");
+chai.eval(R"_(
+    for(var i=0; i<data_list.size(); ++i)
+    {
+      print(to_string(data_list[i].first) + " " + data_list[i].second)
+    }
+  )_");
+```
+
+# Executing Script
+
+## General
+
+```
+chai.eval("print(\"Hello World\")");
+chai.eval(R"(print("Hello World"))");
+```
+
+## Unboxing Return Values
+
+Returns values are of the type `Boxed_Value` which is meant to be opaque to the programmer. Use one of the unboxing methods to access the internal data.
+
+### Prefered
+
+```
+chai.eval<double>("5.3 + 2.1"); // returns 7.4 as a C++ double
+```
+
+### Alternative
+
+```
+auto v = chai.eval("5.3 + 2.1");
+chai.boxed_cast<double>(v); // extracts double value from boxed_value and applies known conversions
+chaiscript::boxed_cast<double>(v); // free function version, does not know about conversions
+```
+
+### Converting Between Algebraic Types
+
+```
+chaiscript::Boxed_Number(chai.eval("5.3 + 2.1")).get_as<int>(); // works with any number type
+// which is equivalent to, but much more automatic than:
+static_cast<int>(chai.eval<double>("5.3+2.1")); // this version only works if we know that it's a double
+```
+
+### Conversion Caveats
+
+Conversion to `std::shared_ptr<T> &` is supported for function calls, but if you attempt to keep a reference to a `shared_ptr<>` you might invoke undefined behavior
+
+```cpp
+// ok this is supported, you can register it with chaiscript engine
+void nullify_shared_ptr(std::shared_ptr<int> &t) {
+  t == nullptr
+}
+```
+
+```cpp
+int main()
+{
+  // do some stuff and create a chaiscript instance
+  std::shared_ptr<int> &ptr = chai.eval<std::shared_ptr<int> &>(somevalue);
+  // DO NOT do this. Taking a non-const reference to a shared_ptr is not 
+  // supported and causes undefined behavior in the chaiscript engine
+}
+```
+
+
+## Sharing Values
+
+```
+double &d = chai.eval("var i = 5.2; i"); // d is now a reference to i in the script
+std::shared_ptr<double> d = chai.eval("var i = 5.2; i"); // same result but reference counted
+
+d = 3;
+chai.eval("print(i)"); // prints 3
+```
+
+## Catching Eval Errors
+
+```
+try {
+  chai.eval("2.3 + \"String\"");
+} catch (const chaiscript::exception::eval_error &e) {
+  std::cout << "Error\n" << e.pretty_print() << '\n';
+}
+```
+
+## Catching Errors Thrown From Script
+
+```
+try {
+  chai.eval("throw(runtime_error(\"error\"))", chaiscript::exception_specification<int, double, float, const std::string &, const std::exception &>());
+} catch (const double e) {
+} catch (int) {
+} catch (float) {
+} catch (const std::string &) {
+} catch (const std::exception &e) {
+  // This is the one what will be called in the specific throw() above
+}
+```
+
+## Sharing Functions
+
+
+```
+auto p = chai.eval<std::function<std::string (double)>>("to_string"); 
+p(5); // calls chaiscript's 'to_string' function, returning std::string("5")
+```
+
+Note: backtick treats operators as normal functions
+
+```
+auto p = chai.eval<std::function<int (int, int)>>(`+`); 
+p(5, 6); // calls chaiscript's '+' function, returning 11
+```
+
+```
+auto p = chai.eval<std::function<std::string (int, double)>>("fun(x,y) { to_string(x) + to_string(y); }");
+p(3,4.2); // evaluates the lambda function, returning the string "34.2" to C++
+```
+
+# Language Reference
+
+## Variables
+
+```
+var i; // uninitialized variable, can take any value on first assignment;
+auto j; // equiv to var
+
+var k = 5; // initialized to 5 (integer)
+var l := k; // reference to k
+auto &m = k; // reference to k
+
+global g = 5; // creates a global variable. If global already exists, it is not re-added
+global g = 2; // global 'g' now equals 2
+
+global g2;
+if (g2.is_var_undef()) { g2 = 4; } // only initialize g2 once, if global decl hit more than once
+
+GLOBAL g3; // all upper case version also accepted
+```
+
+## Built in Types
+
+```
+var v = [1,2,3u,4ll,"16", `+`]; // creates vector of heterogenous values
+var m = ["a":1, "b":2]; // map of string:value pairs
+```
+
+Floating point values default to `double` type and integers default to `int` type. All C++ suffixes
+such as `f`, `ll`, `u` as well as scientific notation are supported
+
+```
+1.0 // double
+1.0f // float
+1.0l // long double
+1 // int
+1u // unsigned int
+1ul // unsigned long
+1ull // unsigned long long
+```
+
+Literals are automatically sized, just as in C++. For example: `10000000000` is > 32bits and the appropriate type is used to hold it
+on your platform.
+
+
+## Functions
+
+Note that any type of ChaiScript function can be passed freely to C++ and automatically
+converted into an `std::function` object.
+
+### General 
+
+```
+def myfun(x, y) { x + y; } // last statement in body is the return value
+def myfun(x, y) { return x + y; } // equiv 
+```
+
+### Optionally Typed
+
+```
+def myfun(x, int y) { x + y; } // requires y to be an int
+```
+
+### With Guards
+
+```
+def myfun(x, int y) : y > 5 { x - y; } // only called if y > 5
+```
+
+### Methods
+
+Methods and functions are mostly equivalent
+
+```
+def string::add(int y) { this + to_string(y); }
+def add(string s, int y) { s + to_string(y); } //equiv functionality
+
+// calling new function/method
+"a".add(1); // returns a1
+add("a", 1); // returns a1, either calling syntax works with either def above
+```
+
+### Lambdas
+
+```
+var l = fun(x) { x * 15; }
+l(2) // returns 30
+
+var a = 13
+var m = fun[a](x) { x * a; } 
+m(3); // a was captured (by reference), returns 39
+
+var n = bind(fun(x,y) { x * y; }, _, 10);
+n(2); // returns 20 
+```
+
+
+
+## ChaiScript Defined Types
+
+Define a type called "MyType" with one member value "a" and a getter
+
+### Preferred
+
+```
+class MyType {
+  var value;
+  def MyType() { this.value = "a"; }
+  def get_value() { "Value Is: " + this.value; }
+};
+```
+
+### Alternative 
+
+```
+attr MyType::value;
+def MyType::MyType() { this.value = "a"; }
+def MyType::get_value() { "Value Is: " + this.value; }
+```
+
+### Using
+
+```
+var m = MyType(); // calls constructor
+print(m.get_value()); // prints "Value Is: a"
+print(get_value(m)); // prints "Value Is: a"
+```
+
+## Dynamic Objects
+
+All ChaiScript defined types and generic Dynamic_Object support dynamic parameters
+
+```
+var o = Dynamic_Object();
+o.f = fun(x) { print(x); }
+o.f(3); // prints "3"
+```
+
+Implicit 'this' is allowed:
+
+```
+var o = Dynamic_Object();
+o.x = 3;
+o.f = fun(y) { print(this.x + y); }
+o.f(10); // prints 13
+```
+
+### Option Explicit
+
+If you want to disable dynamic parameter definitions, you can `set_explicit`.
+
+```
+class My_Class {
+  def My_Class() {
+    this.set_explicit(true);
+    this.x = 2; // this would fail with explicit set to true
+  }
+};
+```
+
+## method_missing
+
+A function of the signature `method_missing(object, name, param1, param2, param3)` will be called if an appropriate
+method cannot be found
+
+```
+def method_missing(int i, string name, Vector v) {
+  print("method_missing(${i}, ${name}), ${v.size()} params");
+}
+
+5.bob(1,2,3); // prints "method_missing(5, bob, 3 params)"
+```
+
+`method_missing` signature can be either 2 parameters or 3 parameters. If the signature contains two parameters
+it is treated as a property. If the property contains a function then additional parameters are passed to
+the contained function.
+
+If both a 2 parameter and a 3 parameter signature match, the 3 parameter function always wins.
+
+
+# Built In Functions
+
+## Evaluation
+
+```
+eval("4 + 5") // dynamically eval script string and returns value of last statement
+eval_file("filename") // evals file and returns value of last statement
+use("filename") // evals file exactly once and returns value of last statement
+                // if the file had already been 'used' nothing happens and undefined is returned
+```
+
+Both `use` and `eval_file` search the 'usepaths' passed to the ChaiScript constructor
+

+Introduction
+============

+
+ChaiScript is one of the only embedded scripting language designed from the 
+ground up to directly target C++ and take advantage of modern C++ development 
+techniques, working with the developer like he expects it to work.  Being a 
+native C++ application, it has some advantages over existing embedded scripting 
+languages:
+
+1. It uses a header-only approach, which makes it easy to integrate with 
+   existing projects.
+2. It maintains type safety between your C++ application and the user scripts.
+3. It supports a variety of C++ techniques including callbacks, overloaded 
+   functions, class methods, and stl containers.
+
+
+Requirements
+============
+
+ChaiScript requires a C++11 compiler to build with support for variadic 
+templates.  It has been tested with gcc 4.6 and clang 3.1 (with libcxx). MacOS 
+10.8 (Mountain Lion) is also known to support the C++11 build with Apple's 
+clang 4.0. MSVC 2013 or newer is supports also. For more information see the build 
+[dashboard](http://chaiscript.com/ChaiScript-BuildResults/index.html).
+
+Usage
+=====
+
+* Add the ChaiScript include directory to your project's header search path
+* Add `#include <chaiscript/chaiscript.hpp>` to your source file
+* Instantiate the ChaiScript engine in your application.  For example, create a 
+  new engine with the name `chai` like so: `chaiscript::ChaiScript chai`
+* The default behavior is to load the ChaiScript standard library from a 
+  loadable module. A second option is to compile the library into your code,
+  see below for an example.
+
+Once instantiated, the engine is ready to start running ChaiScript source.  You
+have two main options for processing ChaiScript source: a line at a time using 
+`chai.eval(string)` and a file at a time using `chai.eval_file(fname)`
+
+To make functions in your C++ code visible to scripts, they must be registered 
+with the scripting engine.  To do so, call add:
+
+    chai.add(chaiscript::fun(&my_function), "my_function_name");
+
+Once registered the function will be visible to scripts as "my_function_name"
+
+Examples
+========
+
+ChaiScript is similar to ECMAScript (aka JavaScript(tm)), but with some 
+modifications to make it easier to use.  For usage examples see the "samples" 
+directory, and for more in-depth look at the language, the unit tests in the 
+"unittests" directory cover the most ground.
+
+For examples of how to register parts of your C++ application, see 
+"example.cpp" in the "src" directory. Example.cpp is verbose and shows every 
+possible way of working with the library. For further documentation generate 
+the doxygen documentation in the build folder or see the website 
+http://www.chaiscript.com.
+
+
+The shortest complete example possible follows:
+
+    /// main.cpp
+
+    #include <chaiscript/chaiscript.hpp>
+
+    double function(int i, double j)
+    {
+      return i * j;
+    }
+
+    int main()
+    {
+      chaiscript::ChaiScript chai;
+      chai.add(chaiscript::fun(&function), "function");
+
+      double d = chai.eval<double>("function(3, 4.75);");
+    }
+
+
+
+Or, if you want to compile the std lib into your code, which reduces
+runtime requirements.
+
+    /// main.cpp
+
+    #include <chaiscript/chaiscript.hpp>
+    #include <chaiscript/chaiscript_stdlib.hpp>
+
+    double function(int i, double j)
+    {
+      return i * j;
+    }
+
+    int main()
+    {
+      chaiscript::ChaiScript chai(chaiscript::Std_Lib::library());
+      chai.add(chaiscript::fun(&function), "function");
+
+      double d = chai.eval<double>("function(3, 4.75);");
+    }
