Other

3.0.0: Support for HHVM and PHP7

Added support for PHP7

• Replaced String classes used in test suite as "string" is reserved as
  type name in PHP7.
  (@thekid)
• Rewrote tests verifying exceptions are raised for argument type
  mismatches to work in both PHP 5.x and PHP 7.X.
  (@thekid)

Fixed issue #39: HHVM support

• Fixed sscanf() incompatibilities - HHVM doesn't support %* for not
  assigning variables. Worked around by supplying dummy variables.
  (@thekid)
• Added a native importer which doesn't verify extensions. HHVM does
  not group functions into extensions like PHP does.
  (@thekid)

Removed support for PHP 5.2 and PHP 5.3

• Added new PHP 5.4 the default emitter, which emits new T().method()
  as (new T())->method() instead of wrapping it in the deprecated
  create core functionality.
  (@thekid)
• Removed PHP 5.2 and 5.3 emitters, using -E php5.2 or -E php5.3
  on the command line will produce an error!
  (@thekid)

Other improvements

• Improved performance when loading supported syntaxes by deferring
  parser and lexer instantiation until when first needed.
  (@thekid)

2.1.0: XP Framework adoption

• Adopted to newer XP versions by no longer using deprecated functionality:
  . Replaced uses() call with class loader API call
  . Replaced raise() with reflection-based creation statement
  . Changed delete() call to use unset language construct.
  (@thekid)

2.0.0: New lambda syntax, namespaces and 5.3 closures

This release contains the following changes:

• Made available via Composer (@thekid)
• Heads up: Changed minimum XP version to run the XP compiler to XP
  6.0.0. It can still generated code to run on XP 5.X-SERIES, but will
  require 6.X-SERIES to run itself (@thekid)
• Added possibility to add default values to lambda parameters. See
  #38 - (@thekid)
• Fixed compiler choking on methods with generic return types (@thekid)
• Allowed omitting the parameter type inside method declarations. The type
  will then be set to var and will be unchecked at runtime (@thekid)
• Changed syntax for lambdas from #{ $a -> $a + 1 }; to $a -> $a + 1;,
  after resolving the grammar conflicts the former was avoiding. The old
  form is still supported but will raise compile-time warnings. It will be
  removed in the next major release.
  (@thekid)
• Changed PHP 5.3 emitter to emit PHP 5.3 anonymous functions for lambdas
  (@thekid)
• Merged pull request #37 to solve issue #36: Support "new T()", "T::const"
  and "T::$static" inside annotations - (@thekid)
• Added backwards compatible emitter (-E php5.2) to create non-namespaced
  code for use with XP 5.8 and PHP 5.2 - (@thekid)
• Changed default behaviour to creating namespaced code (compatible with
  XP 5.9 and PHP 5.3+) - (@thekid)
• Changed "-E" command line argument to support versions: -E name will
  load xp.compiler.emit.name.Emitter, -E name60 will load the class
  xp.compiler.emit.name.V60Emitter - (@thekid)
• Changed all emit*() methods in xp.compiler.emit.Emitter to protected
  (@thekid)
