v.0.16.1

The major new feature in this version is OOP - well, poor man's OOP, that is.

Version 0.16.1 released to crates.io

The README is officially transferred to The Rhai Book.

An online Playground is available.

Breaking changes

• The trait function ModuleResolver::resolve no longer takes a Scope as argument.
• Functions defined in script now differentiates between using method-call style and normal function-call style.
  The method-call style will bind the object to the this parameter instead of consuming the first parameter.
• Imported modules are no longer stored in the Scope. Scope::push_module is removed.
  Therefore, cannot rely on module imports to persist across invocations using a Scope.
• AST::retain_functions is used for another purpose. The old AST::retain_functions is renamed to AST::clear_statements.

New features

• Support for function pointers via Fn(name) and Fn.call(...) syntax - a poor man's first-class function.
• Support for calling script-defined functions in method-call style with this binding to the object.
• Special support in object maps for OOP.
• Expanded the AST API for fine-tuned manipulation of functions.

Enhancements

• The Rhai Book is online. Most content in the original README was transferred to the Book.
• New feature internals to expose internal data structures (e.g. the AST nodes).
