About this page
Below you can find a list of new features introduced since the previous release, along with some background information and examples.
All systems
Language changes
Better support for Delphi-compatible classes
- Overview: Support has been added for nested types (including other classes), class variables and class-local constants.
- Notes: Delphi-compatible.
- More information: class_extensions_examples lists several examples that make use of these features.
Scoped enumerations
- Overview: Support for the {$scopedenums on/off} directive has been added. When scoped enumerations enabled, enumeration elements only be used by fully qualifying them via enumtypename.enumelement.
- Notes: Delphi-compatible.
- More information: http://docs.embarcadero.com/products/rad_studio/delphiAndcpp2009/HelpUpdate2/EN/html/devcommon/compdirsscopedenums_xml.html
Custom deprecated messages
- Overview: Deprecated can now be applied to virtually any syntactic element (including constants and units), and it is also possible to specify a custom deprecation message.
- Notes: Delphi-compatible
- More information:
<delphi> Todo: write example </delphi>
Support for Objective-Pascal dialect
- Overview: On Mac OS X, most system frameworks are written in Objective-C. While it is possible to interface them via a procedural API, this is not very convenient. For this reason, we have created a new dialect called Objective-Pascal that enables seamless interacting with Objective-C code.
- Notes: This new dialect is currently only supported on Darwin-based platforms (including iOS) using the Apple Objective-C runtime. Patches to add support for the GNUStep runtime are welcome.
- More information:
- FPC_PasCocoa explains the basic language definitions..
- FPC_PasCocoa/Differences explains some of the differences between Objective-Pascal and Object Pascal on the one hand, and Objective-C on the other hand.
