Delphi Predefined Conditionals on iOS: IOS, MACOS, MACOS32, POSIX and POSIX32 (via: Conditional compilation (Delphi) – RAD Studio)

Posted by jpluimers on 2014/03/03

Just a reminder to Self after reading Predefined Conditions in Conditional compilation (Delphi) – RAD Studio.

On iOS, these conditional symbols are defined:

  • IOS
  • MACOS
  • MACOS32
  • POSIX
  • POSIX32

For the (x86 based) iOS simulator, CPU386 and CPUX86 are defined.

For iOS physical devices, CPUARM is defined.

For OS X and the iOS Simulator, ALIGN_STACK is defined as some parameters (including Extended) require to be aligned on 16-byte boundaries. For explanation, see the Mac OS X Stack Alignment article by Eli Boling, as well as PC_MAPPED_EXCEPTIONS and UNDERSCOREIMPORTNAME (sometimes een PIC).

Delphi types that cannot be used for TypeInfo

Posted by jpluimers on 2014/03/03

When writing the Spring4D unit tests for GetTypeSize to include as many TTypeKind values, I came across a few types that either did not compile, or were not supported by TypeInfo. I listed them below as I could not find them in the documentation.

I included a test named Test_EnsureAllTTypeKindsCoveredByCallsTo_Test_GetTypeSize_ that verifies that all TTypeKind values except tkUnknown are covered. So future extensions of TTypeKind will make the tests fail.

As a side issue, I really wanted to know if tkUnknown could be emitted by the compiler. It can sort of, for instance by defining discontiguous enumerations, but are incompatible with TypeInfo as well.

osx – How to find out Mac OS X version from Terminal? (via: Super User)

Posted by jpluimers on 2014/03/03

I’m a command-line addict, so this was a great SuperUser question by Željko Filipin:

I know how to find Mac OS X version from GUI: Apple Menu (top left) > About This Mac

Is there a Terminal command that will tell me Mac OS X version?

It was answered by User delfuego:

You have a few options:

sw_vers -productVersion
system_profiler SPSoftwareDataType

These commands led me to this post: Finding OS X Version and Build Information From the Command Line | The Nubby Admin that also showed these commands:

uname -a
osascript -e 'system info'

Where uname shows only the kernal version, oascript gives a ton of information. Read the rest of this entry »
