In this CodeRage session, Bernd Ua shows you the power and benefits of unit testing and mocking with Spring4D open-source framework. Overview of the Spring4D Spring4D is a great open-source framework to leverage the power of Delphi. In this session, you will learn about the mocking framework contained in Spring4D. We will see how easy it is to get started with mocking and mock out interfaces your classes under tests are using. What is mocking? If you are mocking out something you replace a productive implementation with a special implementation for testing, the so-called mock You can write Mocks manually or use ones that have been automatically created by frameworks The difference between mocks and stubs or dummies is some extra code to log and heck calls made to the mock What a Unit test should not do A Unit test should better not use Databases Network access File Systems External Resouces A Configured Environment So, if your unit test uses one of the above it is more likely an integration test. Be sure to watch the CodeRage session to learn more about mocking and mocking practices in action!

MultitrackStudio from Bremmers Audio Design is a multitrack music recording software which supports recording, editing and mixing audio and MIDI tracks. With the growth of Mac worldwide, MultitrackStudio developers felt the urgency of making their application available on macOS. They had previously used Delphi with VCL (Visual Component Library) a visual component based object oriented framework for developing Microsoft Windows applications. When Embarcadero Technologies released Delphi with FireMonkey, MultitrackStudio developers reworked their custom controls to work with both VCL and FireMonkey. The Delphi RTL (run time library functions and procedures) provided them with cross platform versions of most common functions and they could program against any C or Cocoa framework. After writing some Mac specific code including Core Audio and Audio Units, they had a running version on macOS.

Want to know how to evaluate a Python Expression in Delphi using Python4Delphi? Python for Delphi (P4D) is a set of free components that wrap up the Python DLL into Delphi and C++Builder. They let you easily execute Python scripts, create new Python modules and new Python types. This post will guide you on how to use these components, create a VCL application, run a simple python expression in it, and shows the output message. Python4Delphi Demo2 Sample App shows how to Evaluate a Python Expression by typing the python expression in a Memo, execute and show the message. You can find the Demo2 source on GitHub. Check Demo1 on how to run a simple python script in Delphi. Prerequisites: Download and install the latest Python for your platform. Follow the Python4Delphi installation instructions mentioned here. Alternatively, you can check out this video Getting started with Python4Delphi Components used in Python4Delphi Demo2 App: TPythonEngine: A collection of relatively low-level routines for communicating with Python, creating Python types in Delphi, etc. It’s a Singleton class. Some of the key properties for the component listed here. AutoLoad: Enable this property to load the python DLL automatically. It defaults to true. AutoUnload: Enable this property to unload the python DLL automatically. It defaults to true. DllName: By default, it reflects the latest e.g. python39.dll. But you can provide your registered version. DllPath: Physical location of the Python DLL. InitScript: You can provide the python script here to execute implicitly. IO: Associate the TPythonGUIInputOutput component to this property. RegVersion: Registered python version e.g 3.9. UseLastKnownVersion: If you want to use the latest registered Python version installed set this property to True. 2.TPythonGUIInputOutput: Inherited from TPythonInputOutput (which works as a console for python outputs) Using this component Output property you can associate the Memo component to show the Output. MaxLineLength: Maximum character length per line. MaxLines: Maximum python script lines can be executed using this component. OutPut: Associate the Memo component to show the output. RawOutput: Produce the result as raw output. UniCodeIO: Set true to provide Input and output as Unicode. 3.TMemo: A multiline text editing control, providing text scrolling. The text in the memo control can be edited as a whole or line by line. You can find the Python4Delphi Demo2 sample project from the extracted GitHub repository ..Python4DelphiDemosDemo02.dproj. Open this project in RAD Studio 10.4.1 and run the application. Implementation Details: PythonEngine1 provides the connection to Python or rather the Python API. This project uses Python3.9 which can be seen in TPythonEngine DllName property. PythonGUIInputOutput1 provides a conduit for routing input and output between the Graphical User Interface (GUI) and the currentlyexecuting Python script. Memo1, used for providing the Python Expression and Memo2 for showing the output(instead Memo2 used ShowMessage to show the expression result) Buttons to perform the execution, load script from, and save the script to file. On Clicking Execute Button the script expression is executed using the below code. procedure TForm1.Button1Click(Sender: TObject); var Result : PPyObject; begin with PythonEngine1 do begin Result := EvalStrings( Memo1.Lines ); if Assigned(Result) then begin ShowMessage(Format(‘Eval: %s’,[PyObjectAsString(Result)])); Py_DECREF(Result); end else ShowMessage(‘Could not evaluate the script’); end; end; procedure TForm1.Button1Click(Sender: TObject); var   Result : PPyObject; begin   with PythonEngine1 do     begin       Result := EvalStrings( Memo1.Lines );       if Assigned(Result) then         begin           ShowMessage(Format(‘Eval: %s’,[PyObjectAsString(Result)]));           Py_DECREF(Result);         end       else         ShowMessage(‘Could not evaluate the script’);     end; end; EvalStrings will evaluate the Mathematical expression provided in the Memo1 and return the Python Object(PPyObject).

Many times we need to override windows default settings or customize our application by code, irrespective of user settings in windows for better user experience. Your application has been built with options to apply certain themes and the user also has the flexibility to change Windows themes for entire windows/apps. In this case, your application user experience should not be affected by user system settings. This post can guide you to set the themes in your Windows VCL application. How to check whether dark mode is enabled? Press Windows + R -> Type Regedit cmd in Run Command window. Navigate to the folder: ComputerHKEY_CURRENT_USERSOFTWAREMicrosoftWindowsCurrentVersionThemesPersonalize. Check AppsUseLightTheme Keyword and if its value is 1 then the windows apps theme is in Light mode and 0 means it’s in Dark mode. How to set the themes in Delphi from project options : In Delphi IDE, Go to -> Project Menu -> options -> appearance -> Select the available themes suitable for your application. Carbon for Dark theme for example. You application theme settings: If you want to give a better user experience explicitly irrespective of (or) according to windows themes selected by the user in the machine, first programmatically check the app theme mode. Navigate to the following location ComputerHKEY_CURRENT_USERSOFTWAREMicrosoftWindowsCurrentVersionThemesPersonalize and get the keyword AppsUseLightTheme value. Accordingly build your logic of setting the VCL theme using the VCL API to set the themes. Note: Platform specific conditional defines need to be included accordingly if it is cross platform application. Check the below Video for the full demonstration of setting the dark/light theme Vice-versa for a VCL application. Check out the latest Delphi 10.4.1 which supports High DPI Styles and VCL per control styling for your applications.
