I need a safe way to allocate memory for a string variable, without getting exceptions. I don't want to use "try-except" blocks and neither the function that do this, use them internaly. I need a speed optimised method. If there are errors it can return a nil pointer.

 

I checked the GetMem, AllocMem, GetMemory... and they all say that raise exceptions. Although I looked to the GetMemory code but I didn't see any code that raise exceptions. 

You can use SysGetMem, SysReallocMem, SysFreeMem.

Would be interested to see the difference between what dcc64 and fpc emit though - can do share the benchmark code somewhere?

Sorry for dirty adaptation

spritz_bench.zip

Two cent about compilers performance by the example of spritz-c stream cipher implementation:

1. Delphi 11, Windows x86_64 (classic compiler), release

2. Delphi 11, Linux x86_64 (nextgen, LLVM based compiler), release

3. FreePascal 3.3.1, Linux x86_64, release

This number comes maybe from somewhere else

Try to check file version of your delphide280.bpl (or just run Delphi only, not RAD Studio)

Unfortunately I don't have any mac arm to confirm.

You don't need mac to compile units. Just use command line compiler to compile this unit:

unit def;
interface
implementation
{$if defined(MACOS)}
 {$message hint 'MACOS defined'}
{$endif}
end.

Delphi XE2, x86_64, Release:

default - 547840 bytes

+ weaklinkrtti on - 505344 bytes

+ custom rtl build with minimal rtti - 256000 bytes

The same example on 10.4.2:
1770kb, 1279kb, 456kb

How did you produce custom RTL build?

For XE2 you need explicitly rebuild the three files (for latest versons need some more rtl files be rebuilded):
system.pas (with key -Y)
system.sysutils.pas (with key -V-)
system.variants.pas (with key -V-)
(search path should include rtl sources)

When project building seach path should include your own custom rtl dcus, and rtl sources after it.

Um... Aren't you responsible for initializing the record yourself if you have declared an initializer for the record? 

The error is not in the implementation of the custom initializer. A custom initializer is available for the “TRec” type, but an initialization error is in the “TData” type, which does not have a custom initializer, but has a field of a managed type. In the code example, you can replace the custom initializer with any other custom management operator (finalizer, assign), and you will get the same error.

5.5. It also makes sense to change the clHighlightText color for better look of some IDE parts (ObjectInspector, Options Dialogs, New Items dialog).

how would I change "SysColors.clHighlight" from version 10.3.2?

1. Run any resource editor (ResourceHacker, for example) and open ModernTheme260.bpl
2. Extract resource "WIN10IDE_LIGHT" to file *.vsf
3. Open saved file in the Bitmap Style Designer ($(BDSBIN)\BitmapStyleDesigner.exe)
4. In the tree-structure "Objects" find node "SysColors" and item "clHighlight"
5. Change the "clHighlight" to you prefered color
6. Save modified style and close Style Designer
7. Using resource editor replace resource "WIN10IDE_LIGHT" in ModernTheme260.bpl by the modified style file.

p.s. This issue planed to fix soon.

how to export the IDE theme from 10.3.1 to 10.3.2?

Export is not required, it's the same theme. Changed the drawing method.

Your can extract WIN10IDE_LIGHT resource from ModernTheme260.bpl, change SysColors.clHighlight by the BitmapStyleDesigner.exe and replace the style resource.

But it will affects on the some other UI elements, M main menu items, for example.
