XP Language

The download package contains the language's source and a compiler.

Specially developed for the XP Framework, the XP language is based on PHP.

What is new in this release:

• Support for HHVM and PHP7.

What is new in version 2.0.0:

• Made available via Composer
• 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
• Added possibility to add default values to lambda parameters.
• Fixed compiler choking on methods with generic return types
• Allowed omitting the parameter type inside method declarations. The type will then be set to var and will be unchecked at runtime
• Changed syntax for lambdas from #{ $a -> $a + 1 }; to $a -> $a + 1;, after resolving the grammar conflicts the former was avoiding. The old form is still supported but will raise compile-time warnings. It will be removed in the next major release.
• Changed PHP 5.3 emitter to emit PHP 5.3 anonymous functions for lambdas
• Merged pull request #37 to solve issue #36: Support "new T()", "T::const" and "T::$static" inside annotations
• Added backwards compatible emitter (-E php5.2) to create non-namespaced code for use with XP 5.8 and PHP 5.2
• Changed default behaviour to creating namespaced code (compatible with XP 5.9 and PHP 5.3+)
• 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

Limitations:

• As the language itself is written in the XP Framework, no binary or proprietary extensions are needed.
