opal

• Fix regression: add %i[foo bar] style words back to lexer

• Move corelib from opal/core to opal/corelib. This stops files in core/ clashing with user files.

• Reverted RUBY_VERSION to 1.9.3. Opal 0.6.0 will be the first release for 2.0.0.

• Opal now targets ruby 2.0.0

• Named function inside class body now generates with $ prefix, e.g. $MyClass. This makes it easier to wrap/bridge native functions.

• Support Array subclasses

• Various fixes to String, Kernel and other core classes

• Fix Method#call to use correct receiver

• Fix Module#define_method to call #to_proc on explicit argument

• Fix super() dispatches on class methods

• Support yield() calls from inside a block (inside a method)

• Cleanup string parsing inside lexer

• Cleanup parser/lexer to use t and k prefixes for all tokens

• Include native into corelib for 0.5.x

• Move all corelib under core/ directory to prevent filename clashes with require

• Move native.rb into stdlib - must now be explicitly required

• Implement BasicObject#__id__

• Cleanup and fix various Enumerable methods

• Optimized_operators is no longer a compiler option
• Replace Opal.bridge_class() with class Foo < `bar` syntax
• Expose Opal.bridge_class() for bridging native prototypes
• Source maps improvements
• Massive Rubyspec cleanup + passing specs
• Massive Corelib/Stdlib cleanup + fixes
• Massive internal cleanup + fixes

• Remove native object method calls
• Add Struct class
• Add method stubs as method_missing option, stubs enabled by default
• Native is now used to wrap native objects directly
• Fix Hash.new and Hash.allocate for subclasses
• Generate sourcemaps from fragments
• Allow blocks to be passed to zsuper (no args) calls
• Fix yield when given 1 or multiple arguments for block destructuring

• Re-implement class system. Classes are now real objects instead of converted Procs. This allows classes to properly inherit methods from each other.
• Fix exception hierarchy. Not all standard exception classes were subclassing the correct parent classes, this is now fixed.
• Move ERB into stdlib. The erb compiler/parser has also been moved into lib/
• Opal::Builder class. A simple port/clone of sprockets general building. This allows us to build projects similar to the way opal-sprockets does.
• Move json.rb to stdlib.
