Delphi语言功能列表以及引入/弃用它们的版本

Question

在开始之前,我想指出的是,我已经通过谷歌进行了这样的事情,并且无法找到一个,我已经诚实而真实地搜索过.

我要求(对于我正在开发的项目)列出所有Delphi(2007年到最新发布的版本,我不再支持2007年以前的任何版本)"语言功能",以及它们被引入的版本和(在适用的情况下)弃用,改进或删除.

我之前已经在Stack Overflow上注意到类似的问题,尽管其中大部分是以"哪个特征最好"的形式表达的,并且被认为是不合适的.

如果有人知道这样的清单(或有足够的业余时间来编制一个清单),我将非常感激.

接受的答案将包含指向此类列表的链接或列表本身.

总结一下:

Delphi 10.3.x,10.4(尚未推出,这是推测性的)

• 自定义托管记录
• 可空类型
• 支持macOS 64位
• 支持Android 64位

德尔福10.3

• 64位Linux编译器不再使用ARC,而是使用默认的手动托管,这与Windows编译器中的相同.这使得从Windows或OSX到Linux的代码更容易移植.
• 具有自动类型推断的内联变量
• 在Linux上启用8位AnsiChar/AnsiString支持.
• C++ Builder和Delphi现在对所有调用都使用相同的ABI.

德尔福10.2东京

• 支持Linux服务器应用程序(使用LLVM和ARC的Intel 64位).
• @只有在强制转换数组时才允许使用运算符将动态数组分配给指针.
• 更灵活的单元名称命名空间分辨率

德尔福10.1柏林

• 在所有平台上对Utf8String和RawByteString类型的本 机支持
• 的[weak],[unsafe]和[volatile]属性都支持所有的编译器.
• OSX上扩展的大小现在是16个字节.
• 类和记录助手无法访问它们扩展的类或记录的私有成员.
• 支持Android高达6.01.

德尔福10西雅图

• Support for Android 5.1.1 and iOS 8.4
• Improved OSX exception handling

Delphi XE8

• Support for 64-bit iOS;
• New integer types: FixedInt, FixedUInt 32-bit integer types on all platforms;
• New platform dependent integer types: LongInt, LongWord (64-bits on iOS-64, 32-bits on all other platforms);

Delphi XE7

• String-Like Operations Supported on Dynamic Arrays
• Parallel Library added to the RTL

• New compiler intrinsic routines (undocumented):

  function IsManagedType(T: TypeIdentifier): Boolean; function HasWeakRef(T: TypeIdentifier): Boolean; function GetTypeKind(T: TypeIdentifier): TTypeKind; function IsConstValue(Value): boolean;

Delphi XE6

Delphi XE5

• Android Support;
  needs device with ArmV6 + Neon or ArmV7 for deployment
  introduces conditional define ANDROID
• Operator overloading for classes (but only for the NextGen compiler {Android/iOS})

Delphi XE4

• The following new conditionals are introduced/enabled in XE4:
  AUTOREFCOUNT
  CPUARM
  EXTERNAL_LINKER
  IOS
  NEXTGEN
  UNDERSCOREIMPORTNAME
  WEAKREF
  WEAKINSTREF
  WEAKINTREF

  • Reintroduced support for iOS.
  • New dependency directive for specifying the dependencies of an external library (undocumented until XE8).
  • ARC support in NextGen compilers (including TObject.DisposeOf).
    _{Note that much of the groundwork for ARC was already in XE3, but much of it was disabled}
  • Before the XE4 release, $IF statements could only be terminated with $IFEND, and the $IFDEF, $IFNDEF, $IFOPT directives could only be terminated with $ENDIF.

At XE4, this changed so that $ENDIF became an accepted terminator for $IF, $IFDEF, $IFNDEF, and $IFOPT.

Delphi XE3

• Record helpers for built-in types
• Removed support for iOS.
• Atomic intrinsic functions:
  AtomicExchange(), AtomicIncrement(), AtomicCmpExchange(), AtomicDecrement()
• Introduction of the [ref] attribute.

Delphi XE2

• Cross platform support for Mac OSX (32-bit) and iOS;
• Support for Win64;
• Modified RTL to support cross platform;
• Packed Now Forces Byte Alignment of Records (Pre XE2 it did not necessarily do this)

• Eight new DEFINEs have been added:

  ALIGN_STACK
  CPUX86
  CPUX64
  MACOS (Mac operating system)
  MACOS32
  PC_MAPPED_EXCEPTIONS
  PIC
  WIN64

• Full unit scope names are now required in your uses clause.
• {$ExcessPrecision on/off} compiler directive (x64 only)
• The build-in types differ depending on the target platform (32/64-bit)
  • Extended Data Type Is 10 bytes on Win32, but 8 (!) bytes on Win64

Delphi XE

• The {$STRINGCHECKS} compiler directive is ignored in XE;
• New 16-byte value for the {$ALIGN} directive: The acceptable values for the {$ALIGN} directive now include 1, 2, 4, 8, and 16.
• new {$CODEALIGN} directive, this sets the starting address for a procedure or function.
• The {$STRONGLINKTYPES ON} directive
• Support for regular expressions.

Delphi 2010

• Enhanced Delphi RTTI (Run Time Type Information).
• Attributes
• The as operator can be used to cast an interface reference back to the object from which it was extracted.
• The is operator can be used to verify whether an interface reference was extracted from a certain class.
• Normal unsafe casting can be performed on an interface: TObject(SomeInterface).
• new delayed directive indicates that an external library such as a DLL is not to be loaded at declaration time but is to wait until the first call to the method
• Class Constructor/Destructor

Delphi 2009

• Intrinsic type string now maps to UnicodeString;
• {$HighCharUnicode on|off} compiler directive
• Generics;
• function Default(T): T intrinsic function (Undocumented)

  • W1057 Implicit string cast from '%s' to '%s',
  • W1058 Implicit string cast with potential data loss from '%s' to '%s',
  • W1059 Explicit string cast from '%s' to '%s',
  • W1060 Explicit string cast with potential data loss from '%s' to '%s';
• The Exit function can take a parameter specifying a result;
• resourcestrings as Widestrings;
• TObject has a extra hidden pointer to TMonitor in addition to its VMT pointer;
• the deprecated keyword can now have additional text

Delphi 2007

• No language changes that I know of;
  Note that Delphi 2007 is a non-breaking release, DCU's from D2006 will work unchanged in D2007;
• (The .NET 'personality' of 2007 introduced generics)

Delphi 2006

• Enhanced records;
• operator overloading;
• static methods and properties;
• class helpers;
• FastMM is the default memory manager;
• strict private/protected visibility keyword;
• final keyword for virtual methods;
• {$METHODINFO} directive;

Delphi 2005

• for ... in loops,
• inline keyword
• Wildcard in uses statement allowed
• nested types
• nested constants
• {$REGION}/{$ENDREGION} directives

Delphi 7

• three additional compiler warnings:
  • Unsafe_Type,
  • Unsafe_Code, and
  • Unsafe_Cast. These warnings are disabled by default, but can be enabled
• new compiler directive {$WARN UNSAFE_CODE ON}
• Overloads of routines that format and parse numbers, date-time values, and currency using a TFormatSettings structure.

Delphi 6

• [TCustomVariantType][68] provides operator overloading for custom variant types
• New compiler directives:
  • {$IFDEF MSWINDOWS}
  • {$IFDEF LINUX}
  • 在我的博客上,我保留了更新的[Delphi版本之间的更改列表](http://theroadtodelphi.wordpress.com/2009/09/20/hello-world/) (9认同)
  • 神圣的废话延迟了,真是太棒了!升级时他们为什么不给你这个清单! (3认同)

Answer 2

只是为了补充Johan的答案,请在我的博客上查看此条目List of changes between versions of Delphi (Since Delphi 5)以及The TIndex列出自delphi 2005以来的大部分新功能以及每个资源的优秀页面.

Answer 3

Dephi JEDI项目使用的jedi.inc文件公开了一系列功能定义.如果您的项目与MPL兼容,您甚至可以将其用于特征检测,并省去重新发明特定轮子的麻烦.

例如,它定义SUPPORTS_FOR_IN编译器是否支持枚举器.可以将枚举器代码包装在IFDEF对该定义的检查中,而不是检查特定的编译器版本.
