1.1 Known Issues In This Beta Build

● The new Welcome Page is present, but not fully complete:

○ Information loaded from GetIt will not display, and it will show a spinning wheel only.

○ Similarly the buttons at the top do not work.

○ The fonts or general look and feel used in the lists are not final

○ The custom layout are not persistent if you restart RAD Studio

● New IDE icons are not final. Some have errors in the dark theme, and some others will be redesigned or replaced.

● Debugging macOS ARM apps may require some Python configuration. See the documentation below how to do this.

● Warning: Android applications use a new set of Java libraries. When you are creating a new project, it will have the correct references. When you are upgrading an Android project created with a previous version of RAD Studio, you need to update the Java libraries references manually, with these steps. See the section Android 30 API Support.

2 Beta Installation and General Information

The “Olympus” Beta can coexist with any previous version installation (like 10.4.x or 10.3.x) on the same machine or VM, but we recommend installing Beta versions on a separate machine or VM rather than on your primary development machine.

Hardware and operating system requirements for installing and running “Olympus” are the same as 10.4 Sydney, listed here.

2.1 Supported Target Platforms

RAD Studio “Olympus” is expected to support the following target platforms:

Supported Supported UI Languages Frameworks OS Supported Versions Target Platform Delphi C++ FireMonkey VCL

Windows 32-bit ✔ ✔ ✔ ✔ Windows 10, Windows 7 Windows (SP1+), Windows Server 2019 and 2016 Windows 64-bit ✔ ✔ ✔ ✔

macOS Intel 64-bit ✔ ✔ macOS 11 Big Sur, 10.15 Catalina macOS ARM 64-bit ✔ ✔

iOS iOS14 iOS Device 64-bit ✔ ✔ ✔

Android 32-bit ✔ ✔ ✔ Android 11, 10, 9, 8.1 Android 64-bit ✔ ✔

Ubuntu 20.04 LTS and 18.04 LTS, RedHat Enterprise Linux Linux Intel 64-bit ✔ ✔1 Linux v8, WSL2 (Windows Subsystem for Linux)

2.2 Third Party Beta components

Third party components for previous versions of RAD Studio are generally not compatible with the “Olympus” Beta. You can use the Quality Portal RSB issue for sharing binaries or download links with other beta testers.

1 Via FMX Linux, now available from Embarcadero as part of RAD Studio.

2.3 How to log Beta bugs

To log bugs found in the Beta, login to Embarcadero’s Quality Portal using your Embarcadero Developer Network (EDN) credentials.

Attention: Use your username to log in to EDN. Email address is not supported. If you are having trouble logging in, please contact [email protected]. Same if RAD Studio Beta is not in the Project dropdown list.

Click Create issue on the top bar and select RAD Studio Beta from the Project list:

Before logging a bug, please verify that the bug does not already exist in the system. Duplicate bug reports waste time for both the person logging the bug and the evaluator, who has to reproduce it to determine if it is similar to other bugs.

For any additional information on how to log bugs on Quality Portal, please review the RAD Studio Quality Portal user guide.

2.4 Delphi LSP bugs

If you find bugs in code completion or other Code Insight features, please include LSP log files. You can find full info about turning on logs for DelphiLSP here.

Note that log files include source code when a unit is modified in the IDE. Logs also grow fast, so please turn it on only for the time it takes to reproduce the issue (i.e. turn logging on, start the IDE, reproduce the issue, close the IDE, turn logging off.)

2.5 Exception stack trace reporting in the IDE

The IDE exception dialog no longer attempts to automatically send crash reports to our bug reporting system. Instead, it allows you to save the crash diagnostic to a file and provides links to our reporting system. When an exception occurs, you will see the following exception dialog:

Click Save to collect information on the error and save it to a file. You will see a progress bar showing the information collection status.

Then, the Save Report dialog opens and allows you to review and edit the information that was gathered, and save it to a file.

Click Save Report to save the crash report. Follow the steps in “How to log Beta bugs” above, describing the steps that led to the error, and then attach the crash report file that you previously saved.

3 What’s New in RAD Studio “Olympus”

All new features provided in the “Olympus” Beta are not committed until completed and GA released. The remaining sections of the document describe features available in the current beta version and the issues that have been addressed so far, but there is no guarantee that any or each of these features and fixes will be part of the final shipping product (GA release).

As the product beta itself shows in terms of product name, we are currently planning to release the new version of RAD Studio as version 11.0, to match Microsoft’s version number change in the next version of Windows. For more information about the version number change please refer to this blog post.

4 IDE Changes

4.1 Package Cache Disabled

The IDE has a ‘package cache’. Its purpose is to delay loading of packages until they are required. Most cached packages are component packages, and some packages can’t be cached (such as if they register a property editor for a type that affects other packages, like TStrings.) Normally a package would be loaded into memory, but the cache stores the component name, category and images, and the cached values are used in the Palette. The package for a component is then loaded when you drop that component on the form.

It’s been the cause of a number of bugs especially around component icons not refreshing (it stores icons in the registry), and in some cases can be a cause of slowdown loading projects.

The package cache is now disabled by default. In future, it may be removed completely. If you have experienced slowdowns opening projects, please test in this beta to see if those slowdowns are resolved.

4.2 Welcome Page

The old Welcome Page has been removed, and a new VCL-based Welcome Page has been added to the IDE.

Warning: In this version, the Welcome Page is incomplete and some parts are not fully functional. This includes the GetIt-based frames not displaying content, and the buttons at the top not doing anything when clicked. Please see the Known Issues section.

The Welcome Page, with some customizations

The new Welcome page is designed to:

● Have multiple frames, which can be added, removed, or their position and size rearranged as you wish ● Scale well with high DPI ● Use our own technology (the previous Welcome Page used HTML and an embedded browser) ● Solve bugs in the old implementation, such as opening links in the default browser ● Have an open architecture. In this release, we are not publishing the interfaces (to allow for ‘bake time’, to ensure the interfaces provide everything they need) but we plan in future to publish the interfaces in the ToolsAPI allowing anyone to create a Welcome Page frame

The new Welcome Page will display when you start the IDE. The main things to test this release are:

● The Create frame, which should display the same contents as File > New, and be able to be toggled between Delphi and C++ ● The Open Recent frame. As well as listing recent projects, it lists recent files. You can favorite any item in it which will display at the top. ● Editing the layout. Click the Edit Layout button on the bottom left of the Welcome Page. This opens a layout editor (see image below) ○ You can add and remove frames ○ Frames are placed in a grid. This is intended to allow a very flexible layout ■ You can add or remove rows and columns to this grid ■ Select a frame in the grid to move it, or to expand it vertically or horizontally

The Welcome Page Layout editor dialog box

4.3 High DPI IDE

The Delphi, C++Builder and RAD Studio IDE is now high-DPI enabled. By default, the IDE runs as DPI-unaware, as in previous versions. Running with high DPI enabled is currently a runtime option.

To run the IDE with high DPI support, run bds.exe on the command line or through a shortcut with the following flag:

>bds /highdpi:permonitorv2

Warning: In a future beta, and the final release, we plan to make high DPI enabled by default so that this command-line parameter will be unnecessary. Your feedback if this is the right decision is much appreciated.

Note: to force the IDE to run DPI-unaware, use:

>bds /highdpi:unaware

(or in the current beta, don’t use a command-line parameter at all.)

All windows in the IDE should now support high DPI. This includes behavior such as changing scale when being dragged from one monitor to another. IDE functionality includes:

● The IDE main window ● All dockable windows: Object Inspector, Projects, Structure, Messages, Breakpoint, Watch, Local Variable, Data Explorer, and so forth ○ All Object Inspector property editors ● All dialogs: New Items, IDE Options and Project Options (and all pages in those dialogs), Compile, About, and so forth

● All content windows: the editor, form designers (more on these below), History, type library editor, and so forth.

Note: The code editor currently still uses Courier New 10pt as its default font. We’re considering setting the default to Consolas 10pt, and shipping other common coding fonts with the IDE. Your feedback on what fonts will be appreciated. The editor does not support ligatures in this version.

Attention: The HTML-based Welcome Page does not support high DPI. It will be replaced with a VCL-based implementation in a future beta.

The FMX and VCL form designer support for high DPI is noted below. Please read it. The VCL designer support is complex and we seek beta feedback.

The IDE styles (Light, Dark and Mountain Mist) have been updated to support high DPI.

IDE images, including toolbar icons, the screenshots in the First Start dialog, and elsewhere have been increased in resolution.

The IDE internally uses a TImageCollection and multiple TVirtualImageList components, the same components we recommend for customer applications. All ToolsAPI APIs that refer to images have been updated to pass multiple resolutions of an image (details in the ToolsAPI section below.)

Note: Some icons are beta quality (see note below) or not yet replaced, and in some areas, we have chosen not to update the icons or images to high-res in this version. That decision has been made only for rarely used areas of the IDE. If there is an area without high-res icons which you believe we should address, please file a bug report. Even without updated icons, all areas of the IDE should still scale correctly.

4.3.1 High DPI for the VCL Form Designer The most complex part of high DPI in the IDE is the form designer. By and large the rest of the IDE is the same as any other VCL app (with some exceptions) but the VCL designer is unique. There are significant technical challenges to having a window, such as a designed form, at a different DPI than the IDE it is hosted in. However, there are downsides to always scaling a form, such as having different values streamed to DFM due to the monitor it was opened and designed on, as well as loss of positioning precision if a form is repeatedly rescaled. We’ve done considerable research and prototyping to ensure we have a solution that addresses the multiple different needs that different development teams may have. We strongly seek your feedback on this solution and the best default behavior for the IDE.

In RAD Studio 11.0, the VCL form designer can handle scaling three different ways.

High DPI settings in IDE Options > VCL Form Designer

Note: When changing the ‘VCL Designer High DPI mode’ setting, you need to close and reopen the designer for it to have effect. (We expect to change this in a future beta.)

First, the VCL designer can simply not scale the form at all (‘Low DPI (96 PPI)’). This leaves the designer running at 96PPI, the same pixel size as if the IDE were running DPI unaware. If the IDE itself is running high DPI then the designed form will appear smaller than you’d expect, because its pixel-size - its scaling - is 100% no matter the scaling of the IDE around it.

Note: ‘Low DPI’ is the default in this beta. You need to change this setting in order to test the VCL designer’s high DPI support. We expect to change the default in a future beta.

4.3.1.1 Scaling The other options both scale the form using the VCL’s perMonitorv2 scaling support, the same way a form is scaled at runtime, the support for which is now extended to designtime.

1. The easiest of the two options is to scale the designer with the monitor it is on (‘Automatic’). If the IDE is running at 200%, so is the designer: specifically, the form designer will scale the form to the same PPI as the display that the designer is placed on.

2. The other option is to lock a form to be designed at a specific PPI (‘User Editable’). For example, you can specify a form is always designed at 192PPI: this means that no matter the scaling of the screen your form designer is on, the designer will display and design that form at 200%. (If the monitor and this setting have different PPIs, the displayed form will appear relatively smaller or larger than other controls in the IDE.) The scale to use is a per-form setting and is currently controlled via the PixelsPerInch property in the Object Inspector.

These two settings scale the form at designtime just as it is scaled at runtime. This means that the pixel values of control size and location change in the DFM based on the PPI at which the form was designed. That is, when a form that was last designed at 96PPI (or unknown PPI, as for forms from previous version) is designed and saved at another PPI, Left, Height, Padding, etc. will all be saved in the DFM with a different value.

At runtime, the form is scaled from whatever its design PPI was to the display PPI. This uses the same system as before v11.0, except that in prior versions the design PPI was always assumed to be 96PPI.

Note: Frames are not scaled in this beta. They will only be scaled if they are placed on a form. We plan to address this in a future beta.

4.3.1.2 FAQ and Notes: ● TForm.Scaled must be set to True for scaling to take effect in the designer.

● If multiple team members design a form, the PPI at which they design it can be different each time the form is designed (based on their personal computer configuration.) This means that the form will rescale when it is opened for design, and saved and checked into source control with different pixel values. This may also mean loss of precision - controls’ position or size changing - if a form is repeatedly scaled up and down.

○ To mitigate this, we’ve added the ‘User Editable’ option: a team can use this option and set the PixelsPerInch property to ensure a form is always designed and saved at a specific PPI.

● The designtime PPI is stored in the PixelsPerInch property. If your IDE’s VCL design scaling is set to User Editable, this is a writable property. Enter a PPI value to scale the form to that PPI in the designer. If the IDE’s VCL design scaling is set to ‘Low DPI’ or ‘Automatic’, this property is IDE-managed and is read-only.

○ PixelsPerInch is an existing property. Its meaning is now overloaded. In the past, before 10.3 (where it stopped having meaning) it had meaning at runtime only, for a short time (it was used to initialize the CurrentPPI property for a control.)

4.3.1.3 Questions for beta testers Please test the following areas and consider the following questions.

We have spent considerable time researching this before implementing, as well as testing, but this is an important and complex area. We suggest testing the following areas:

● A form originally designed on Windows 7’s ‘Large Fonts’ scaling (120PPI.) You may well have trouble designing such a form already because until v11 the form designer assumed 96PPI; what is the situation with this new behavior? What if you edit the DFM to set PixelsPerInch to 120? For your forms, is it already set to 120? ● A form designed in Delphi up to 10.2, where the PixelsPerInch property is set. Please also look at old versions - Delphi 7, for example. ● What happens if you move the designer between two monitors of different scales often? The VCL uses integer coordinates and so at runtime it is possible to lose positioning correctly - the same will happen at designtime. How should we handle this? ● Forms designed before v11.0. Do they display and design correctly with each of the designer settings? ● Forms designed at each of the three settings. Do they display and design correctly if you change the designer setting and reopen the form? ● If you have multiple team members with machines with different scaling, please test using the Automatic setting and then each editing the same form. Does this work well or does it cause problems for you, either in control positioning or in source control changes? ● If you design at high DPI, e.g. 200% or 250%, does your app behave and scale correctly when you run it at 100%?

There are some smaller areas that are not around the fundamental design but around UX or workflow which we’d also like feedback on:

● Which of the three designer scaling settings (Low DPI, User Editable, and Automatic) is the best default in the final release? Automatic is the easiest and makes the designer look ‘right’ when you first open it -- but given it can be a

different scale per developer, would that cause too many problems for teams or source control? ● Locking a form to a specific PPI is currently done on a per-form basis. Should this be an IDE-level setting? (Or project-level, but a form may be in multiple projects; we often avoid project-level settings for this reason and so we’d likely go IDE-level for this setting.) ● Should we change the User Editable behavior so that instead of editing a property in the Object Inspector, the designer scaling and form PPI are set elsewhere? (E.g., the FMX designer has a toolbar: some equivalent for the VCL designer, or controls near the form placement control in the bottom right.)

4.3.1.4 Other notes

The ‘Scale grid size / snap tolerance to design PPI’ setting affects the behavior of the visual grid on a form. (By default, this draws a dot every 8x8 pixels, though this is configurable.) When this checkbox is checked, the value (e.g. 8x8) is scaled the same as the form.

Note: Do you find this setting useful? If scaling, should the grid and snap always scale with the form scale?

The form positioner (in the bottom right of the form designer) supports high DPI.

4.3.2 High DPI for the FMX Form Designer The FireMonkey designer scales a form the same way a FMX form does at runtime. Coordinates remain the same (that is, a button placed at (20, 20) will be at (20, 20) no matter the high DPI scaling of the monitor the FMX designer is on.) It is a visual scaling only.

4.3.3 Reporting High DPI Issues When filing bugs about high DPI issues, please include the following information:

● Windows version or build ● Both your scaling and resolution settings ○ Is it a multi-monitor system? Please include the specific scaling and resolution for each monitor ○ Depending on the issue, a screenshot of the display arrangement may be important as well:

● What graphics card is it? ● Are you running on a virtual machine, and if so which one (e.g. VMWare Fusion, Parallels, etc.)? ● Are you running over a remote desktop? ● Are there any other Windows settings that might affect the issue?

4.3.4 New Icons All new set of IDE icons (with multiple resolutions.) The IDE uses the virtual image list throughout. Note that some of these icons will be further replaced in a future beta, and that some icons have glitches (e.g. white backgrounds) in the dark style.

4.4 Open Tools API Changes

All APIs that pass images, such as the splash screen services, about box, IDE Insight, and other areas have been updated to support high DPI images. Each interface has a new overload of relevant methods that take a TGraphicArray (defined as an array of TGraphic.) This allows you to pass in multiple resolutions of the same icon, which are added to the internal image collection and used with a virtual image list.

For example, IOTASplashScreenServices280 is the new splash screen interface for v11 and adds overloads for AddPluginBitmap and AddProductBitmap, where instead of passing a single HBITMAP you pass an array of images:

procedure AddPluginBitmap(const Caption: string; AImageArray: TGraphicArray; AIsUnRegistered: Boolean; const ALicenseStatus, ASKUName: string); overload;

Although the methods take an array of any TGraphic, we recommend PNG images.

Component vendors should update packages to use these new interfaces, so that logos and icons will draw crisply at high DPI. In addition, the enum type TOTACompileMode was incomplete (did not have all values it should have had) and has been fixed.

4.5 VCL Styles in the Designer

VCL controls can be optionally rendered using styles in the designer.

Warning: This feature is not enabled by default in the current beta and can be turned on in the Tools Options dialog, User Interface > Form designer section. The option name is “Enable VCL Styles”.

The StyleName property editor reflects the available styles in the project, and renders a preview (how a button looks). Remember that if you select “Windows” it means platform styling and if you leave the property empty, it is going to use the parent control (or parent form) style.

Rather than using the classic Windows frame, the VCL form designer now has a custom Windows 10-style title bar and frame. This uses a Windows 10 style if no form style is set, or the frame reflects the selected style of the form if the form is set to use a VCL style, as you can see in the image above.

4.6 Form Designing and Code Editing

In 10.4.2, we introduced having the form designer and the code editor open in two edit windows. There were some bugs which have been resolved. In addition, we have made some behavior changes. Previously, the Design tab was disabled when a form was being designed in another window. Now, the tab is always enabled, but if it is being designed in another window a message is displayed; you can click a button to bring the designer to the current window.

4.7 Options Dialog Performance

The Options dialogs (both IDE and Project Options) should load in a fraction of the time of previous releases.

This is implemented by lazy-loading the options panes. In the past, all pages were loaded when the dialog opened; now, a page is loaded (and controls created) only when it needs to be shown. All pages should be independent, but beta testing would be appreciated to ensure there are no unexpected interactions that this causes an issue with.

Third party vendors should be aware of this change for impact on their settings frames.

4.8 FireMonkey Design Guidelines and Margins

The FireMonkey designer in Olympus is introducing guidelines and other features found in the VCL designer, with a different implementation. Here are some of the new features:

1. Components hints are displayed for components and when you are moving or resizing them.

2. Controls offer guidelines for alignment on the sides (there is no plan to have a base text alignment, due to the complexity of text positioning for styled controls):

3. Controls display standard margins distance with a line across and distance indication when this matches margin or padding distance:

4. The form and component resize controls (grab handles when a control is selected, and the form or frame design edge to resize) have been changed to use the same look and feel as the VCL form designer.

4.9 DelphiLSP for Visual Studio Code

In RAD Studio 11 DelphiLSP can be used with other editors. As part of this, we have created a Visual Studio Code extension using DelphiLSP.

When we release Delphi 11 this extension will be placed on the Visual Studio Marketplace. For beta testing, it is available as a separate download at: altd.embarcadero.com/releases/studio/Beta/Olympus/delphilsp-vscode-1.0.0.zip

To install, locate the delphilsp-v1.0.0.vsix file, then follow these Stack Overflow instructions.

Visual Studio Code using the DelphiLSP extension, here providing code completion. Other features, such as navigation, hover, and so forth are also available.

4.9.1 Using DelphiLSP with a Delphi project in VSCode DelphiLSP needs to understand your Delphi project within a VSCode workspace. It does so by reading a JSON file containing key project settings. To generate this JSON file, turn on ‘Generate LSP Config’ in the Delphi Code Insight settings, and then open a project. The file will be created alongside the .dproj, with the same filename but a ‘delphilsp.json’ extension (e.g., the config file for myproject.dproj will be myproject.delphilsp.json.)

Check this checkbox to generate the DelphiLSP JSON config files when a project is opened.

In Visual Studio Code, a workspace is a different concept to a project. When you open a workspace - say, open a folder which contains Delphi source - and open either a .pas or .dpr file, DelphiLSP will look for a project config file. (The extension is activated only when you open a Delphi source file, not when you open the folder or workspace.)

Notification shown when a project configuration file is found and loaded.

If no config files are found, or if multiple are found, you will see a small prompt to choose one. Clicking this will take you to the plugin settings, which you can also open manually. Ensure you set the settings file path on the Workspace tab:

DelphiLSP settings in VSCode. The Workspace > Settings File setting must point at the .delphilsp.json configuration for your project.

The path to the Delphi LSP executable (See the User settings, not Workspace) should be automatically set, but if it is not then point it at the bin\delphilsp.exe file in your installation.

For more information on User vs Workspace settings, please see this VSCode documentation. Workspace settings override User settings, which is why the path the delphilsp.exe should be set in the User settings, but your current project configuration should be set in the Workspace settings.

Once configured, you should be able to use LSP features with your Delphi code in Visual Studio Code.

4.9.1.1 Filing Bug Reports To debug issues and file bug reports:

● Turn on logging: in the DelphiLSP settings, set Log Modes to 255 (a bitmask for all info). Logs are not written to file, but shown in VSCode. Thereafter, follow the same steps to file a DelphiLSP bug report as you would from within Delphi. Make sure you attach the .delphilsp.json file you are using. ● To see more of the communication within VSCode itself, you can also open the Output view: ○ Open the command palette and type "Focus Output View" ○ Select DelphiLSP in the drop-down menu ○ You should see log messages sent from the server to the client in real time

4.9.2 Using DelphiLSP with Other Editors Only the VSCode extension is supported. However, the following documentation may be useful if you want to test DelphiLSP with other editors.

DelphiLSP only communicates over standard (console) I/O.

4.9.2.1 Initialization

LSP allows custom initializationOptions within the initialize request. This is an example of a valid initialization request:

{

"jsonrpc": "2.0", "id" : 1, "method": "initialize", "params": { "processId": 4711, "rootUri": "file:///test/VSCode/Playgrounds", "initializationOptions": { "serverType": "controller", "agentCount": 2, "returnDccFlags": true, "returnHoverModel": true, "storeProjectSettings": false } } }

The fields are as follows: serverType

Defines the operation mode of DelphiLSP:

● "controller": The server will spawn agentCount DelphiLSP sub- processes (agents) that work with the controller in order to answer requests. The controller acts as a proxy between the IDE and the agents. When an agent terminates or stops responding to requests, the controller will replace it with a new fresh agent. Requests can be processed by multiple agents in parallel. (Note: We only support, and have only tested, configurations with up to two agent processes. One is used for Error Insight, and the other to handle all other LSP requests, such as code completion. This is one agent and one linter.)

● "agent": The server runs in single process mode. The server can only handle one request at a time. It is not possible to get error insight (diagnostics) in this mode. ● "linter": The server runs in single process mode. The server cannot process any language feature requests such as code completion. It is dedicated to error insight. Errors, warnings and hints will be provided through the textDocument/publishDiagnostics notification

The default value is "agent". Use “controller” paired with an agentCount of 2 to get the same behavior as the Delphi IDE and the default behavior of the VSCode extension. agentCount

Defines the number of sub-processes to be spawned when serverType = "controller".

● agentCount <= 0: agentCount will be set to 1 ● agentCount = 1: One sub process with serverType = "agent" will be spawned ● agentCount > 1: [agentCount - 1] sub-processes with serverType = "agent" will be spawned. One sub process with serverType = "linter" will be spawned.

The default value is 2. returnDccFlags

If true then code completion items will carry some additional information from the compiler. The IDE uses this data to display types of code completion that are not defined in the LSP specification, such as procedure or type.

The default value is false. returnHoverModel

If true then textDocument/hover will return a JSON object instead of text/Markdown.

The default value is false. storeProjectSettings

If true then the settings sent through workspace/didChangeConfiguration will be generated and saved to %currentDelphiProject%.delphilsp.json. When DelphiLSP is used with a third-party editor then it can use this file to get project settings. See the configuration.settingsFile property.

This flag will only be evaluated when used by RAD Studio, and is how Delphi causes the .delphilsp.json file to be created.

The default value is false. enableFileWatcher

If true then DelphiLSP watches directories for changes in order to detect file modifications. If changes are detected, it refreshes based on the new contents of the file. This only has an effect for files that are not open in the editor: for files that are open in the editor, the editor is responsible for ensuring the LSP server has the current file contents.

The default value is true.

4.9.2.2 Configuration

LSP allows custom settings within the workspace/didChangeConfiguration notification. This is an example of a valid notification:

{ "jsonrpc": "2.0", "method": "workspace/didChangeConfiguration", "params": { "settings": { "settingsFile": "file:///C%3A/Test/SampleProject.delphilsp.json" } } } settingsFile

URI of a .delphilsp.json settings file that has previously been created with storeProjectSettings enabled; that is, when the Delphi IDE ‘Generate LSP Config’ setting is checked in the Code Insight options.

The ability to load settings from a configuration file is only active when DelphiLSP is used by third party editors. When used from Delphi, the IDE communicates directly.

4.10 Code Insight (DelphiLSP) Improvements

4.10.1 Classic Code Completion Removed Delphi classic code completion has been removed from the IDE. Only the LSP option is available for Delphi Code Insight.

4.10.2 DelphiLSP We are aiming at improving Delphi LSP quality and adding some extensions to the features available in 10.4.2.

● DelphiLSP can locate include files. Failing to handle files included in Delphi units was the main known cause of projects that did work with classic code completion not working with DelphiLSP. We still do not support code completion inside a .inc file, but using a .inc file in a .pas file is now understood by DelphiLSP. ● DelphiLSP agent processes will terminate themselves when there is an AV in the compiler DLL. The controller process will create a new replacement agent. This means that if the server encounters an error, instead of staying unstable or not producing results, it will restart. ● Ctrl+Shift+Up/Down works when the method signatures are slightly different (such as when you have edited the parameters for a method, and want to go to the declaration in order to edit it to match) ● Code completion handles forwarded procedures ● Code completion now suggests arrays, when array items are compatible for assignment ● Fixed an issue where a didChangeNotification was not set to the server when a file was removed from a project ● Fixed an issue where ctrl-click navigation did not work when only DCP files were referenced ● Delphi code completion should now display reserved words and templates again (if enabled in the Options) ● Code Completion can complete on Tab key ● Error insight now working for include statements with relative paths ● Improvements to when a server is restarted, if the server crashes or stops responding ● Ctrl+Click now works when only a DCP is referenced ● An issue with the completion results for dereferenced pointers is resolved ● Completion works for identifiers starting with “Is”, and after “is” ● Better completion for type helpers, including the name shown in UI ● Issues around forward-declared methods resolved ● An issue where changes in a unit were not visible when completing is resolved ● Find Declaration works with type helpers with overloaded methods

4.11 Warning for Build Events

Build events can execute arbitrary commands on your system. It is common to get projects, which include build events, from third parties online.

RAD Studio now warns when a project contains a build event in any configuration (including one you are not currently building.)

Prompt notifying you this project contains build events. Click Yes to continue building; No to stop.

Check ‘Always trust this project’ to trust this project in the future as well, and you will never be prompted when you build this project again.

Trusted projects are stored by path in the registry, so if you move the project the IDE will prompt again. Projects are not stored by version, hash, or other data, so it is possible to mark a project as trusted, get a newer modified version (eg by pulling from remote source control), and not be warned even if a project has a build event it did not before. Therefore, this is a security mitigation intended to assist you, but must not be taken as fully preventative in all situations.

Note: Feedback on this feature is much appreciated. It is intended to improve security when using projects from potentially untrusted or potentially compromised sources.

Feedback on this feature is much appreciated. It is intended to improve security when using projects from potentially untrusted or potentially compromised sources.

4.12 Custom Port for Win64 Debugger

The IDE and the Win64 debugger communicate via a socket, if that’s in use you’ll see an error as you start debugging.

In particular when WSL2 is installed (that is, Windows Subsystem for Linux), the Win64 debugger can fail saying ‘unable to create process’, or with a message that a port is in use.

To resolve this and similar issues, you can now define the DBK_DEBUG_PORT environment variable to override the default port number.

4.13 General IDE Changes

Most IDE work has been focused on high DPI, as covered above. Additional IDE improvements include:

In build 6121:

● The DesignIDEResources package is now available ● The default editor font is now Consolas, with a fallback of Fira Code. The First Use dialog also has an editor font setting on the first page. Note that the editor does not support ligatures, so advanced settings of fonts like Fira Code are not available. (Ligature or other advanced rendering support is not planned in this release.) ● The SVN UI packages are now marked runtime. These were originally designtime, so that they could be extended. ● The Code Insight progress bar is hidden once work is completed ● An issue where the IDE consumed very high numbers of GDI handles was resolved ● A bug where the scrollbar for the code completion window could remain on screen has been resolved ● An issue where the action list editor would not open if images were not assigned to the component has been resolved

● A large number of high DPI issues have been resolved, in areas including the Object Inspector and property editors; dataset field list, assign dataset dialog, edit dataset dialog; data bindings; the breakpoint list; the virtual image list and image collection editors; and the Add Reference dialog.

In previous builds:

● Fixed a performance issue with the View Units dialog ● Fixed some localization issues ● Some crashes when running the IDE unthemed have been resolved ● VCL styles in the form designer are supported for non-visual components ● Mouse wheel scrolling is supported in Object Inspector dropdown lists ● Some stability issues around startup (caused by background loading of component images) have been resolved ● The "cursor position" status bar panel can be clicked to show the "go to line number" dialog ● The image collection editor now supports Ctrl+C to copy the selected image to the clipboard ● A bug where the mouse area that would close a tab did not fully correspond to the area the close button was drawn (it was offset by a pixel) has been resolved. ● ‘FireMonkey Metropolis Application’ is no longer listed in the New Items dialog. ● Fixed an issue where the IDE might look for the (old, and removed) Documentation page. ● An issue where the IDE flickered immediately after startup is now resolved, as is flicker when choosing ‘View Source’. ● An issue where opening the Load Process dialog twice in a row would cause a crash is resolved. ● Some German localization text truncation issues have been fixed, especially in the virtual image list editor. ● The Guided Tour package has been removed. ● The fonts in the navigation toolbar at the top of the code editor have been resized to follow the IDE font sizes.

● ‘View Messages’ has been restored to the code editor context menu ● The Library Path dialog now works well when resizing. ● Issues where some dialogs had the wrong control focused have now been resolved. ● Some more instances of TListView, which cannot be fully styled, have been replaced with the virtual treeview. ● The Select Platform, Build Tools, Go To Line Number, Open From Version Control, Select Remote Profile, Attach To Process, various list editor dialogs, Watch Editor, Evaluate, Breakpoint, Creation Order, Directory Select, Use Unit, Use Form, various wizards, Search and Search Progress dialogs now use the IDE-styled title bar. ● Fixed a number of styling issues, AVs, and miscellaneous bugs.

5 Delphi Compiler Improvements and New Platforms

In general terms, we are not expecting major Delphi language improvements in this cycle, given the focus on supporting a new platform (macOS 64 ARM) and compiler performance, also for the LSP backend.

5.1 New macOS ARM 64-bit Target Platform

Olympus supports a new Delphi target platform, macOS ARM 64-bit, to natively target the new M1 Apple Silicon CPUs with macOS 11. You can use this platform to build native M1 applications (of course this requires M1 hardware to run). We’ll keep our Intel 64-bit target support and the creation of Universal Binary applications including both ARM and Intel binaries in a single package.

By now, you should be able to create all types of supported applications: console applications, basic FireMonkey applications, FMX applications using database features, and leverage the universal version of embedded InterBase, IBLite.

5.1.1 Universal binaries You can create a universal binary containing both Intel and ARM code. To do so, ensure the target platform is macOS ARM 64-bit. In the Project Options (ensuring macOS ARM 64-bit is the current target) navigate to Building > Delphi Compiler > Compiling > Other, and check ‘Generate macOS universal binary file (x86_64 + arm64)’.

Notice that to obtain a universal binary you need to deploy the application. The deployment manager combines two binaries into one single “Universal” binary before transferring the application to the target macOS. You can find the universal binary file under the OSXARM64\Debug folder.

5.1.2 M1 Debugging Requirements

Attention: A different debugger is used for M1 ARM debugging than Intel debugging. This debugger’s evaluator does not support Delphi syntax. Evaluation, such as in the Evaluate/Modify dialog, Watches, and so forth need to be in C++ syntax. This means use of double-quotes for strings, and writing expressions as case-sensitive.

PAServer works on M1 Mac hardware. However, there are issues when debugging for the iOS/64 target on a M1 device.

5.1.2.1 LLDB Python Requirement PAServer uses LLDB on macOS ARM, which requires Python 3.9. The upcoming macOS Monterey will include Python, so we believe the following steps will only be required on Big Sur.

If you get the following error:

then you will need to configure Python on your machine.

Warning: In the past we recommended installing Python via HomeBrew. This is no longer required. If you no longer use it and want to remove it, you can type: brew uninstall python3

XCode includes Python 3.8.9. You can use XCode’s version by running the following commands in your terminal.

is normally /Applications/Xcode.app.

Open Terminal and run:

● cd /Application/PAServer-22.0/Contents/MacOS/lldb/lib/python3.9 ● sudo rm Python ● sudo ln -s /Contents/Developer/Library/Frameworks/Python3.framework/Versio ns//Python Python

If the is not /Applications/Xcode.app, you need to set PYTHONHOME to where the Xcode copy of Python is located before you launch PAServer. In your terminal:

● export PYTHONHOME="/Applications/Xcode 12.2.app/Contents/Developer/Library/Frameworks/Python3.framework/Version s/3.8" ● open /Applications/PAServer-22.0.app

5.1.3 MacOS Deprecations ● In the Olympus release, Macapi.QTKit unit is deprecated on macOS/X64, and it’s removed from macOS/Arm64 library, given Apple removed QTKit from macOS/Arm64.

● We removed the "Macapi.Quicktime" unit from the product for both the macOS/X64 and the Arm64 libraries.

5.1.4 Predefined Compiler Symbols for Apple Platforms The following symbols are major differences among three compilers. Other predefined symbols are covered here.

Compilers Symbol dccosx64 dccosxarm64 dcciosarm64

CPU64BITS ✔ ✔ ✔

CPUARM ✔ ✔

CPUARM64 ✔ ✔

CPUX64 ✔

OSX ✔ ✔

OSX64 ✔ ✔

IOS ✔

IOS64 ✔

POSIX ✔ ✔ ✔

POSIX64 ✔ ✔ ✔

PIC ✔ ✔ ✔

EXTERNALLINKER ✔ ✔ ✔

Historically, MACOS means “it is a Darwin platform”: all of Apple operating systems are Darwin variants. So, all macOS and iOS targeted Delphi compilers define MACOS (even if this sounds a bit confusing today, given that the current name of the operating system originally known as OS X is macOS -- our compiler level symbols will keep reflecting the original name).

5.2 Binary Literals and Digit Separator

The Delphi language in Olympus adds support for binary literals, in addition to decimal and hexadecimal ones. A binary literal uses the % symbol as a prefix (the same syntax used by other Pascal compilers): const Four = %100; var x: Integer; begin x := %1001001;

The language also introduces a digit separator that can be used to improve the readability of literal values with many digits. The separator is the underscore “_” and it is basically ignored when parsing and compiling the code. This is very similar to the feature introduced in C# 7.0. const AMillion = 1_000_000;

Of course, you can use the digit separators for binary literals.

5.3 Inline assembler support for AVX instructions (AVX-512)

We have introduced support for asm code for newer sets of instructions, including AVX2 (ymm) and AVX512 (zmm).

Attention: You’d need an AVX-512 compatible CPU (like one of the recent INTEL CPUs) to test this feature. You can find more information at: https://en.wikipedia.org/wiki/Advanced_Vector_Extensions#CPUs_with_AVX-512

6 C++ ToolChain Improvements

6.1 New C++ Code Formatter

The code formatter technology used for C++ has been completely replaced. Code formatting now uses clang-format.

The new formatter options are not found in IDE Options > Language > Formatter; that section now contains only Delphi formatting. To configure C++ formatting, go to Language > C++ > Formatting.

You can always format code manually, but you can also have the IDE automatically format your code when you save, or even as you type. These last two are controlled by the ‘Auto formatting’ setting. Set it to format on save, or format on newline.

6.1.1 Manually To format code, press Ctrl+D. You will be prompted for confirmation. You can format either the whole file, or a selection.

6.1.2 Format On Newline A powerful feature in other editors is the ability to format code as you type. In C++Builder 11, the code editor can optionally format your C++ code each time you press Enter to add a new line.

Clang-format is not fast. The settings offer a max line limit for your code, after which auto-formatting will not occur. By default, this is set to one thousand (1000) lines.

6.1.3 Formatting Style Clang-format comes with several predefined formatting styles. Select which one you want to use.

In a future beta, we will have an Embarcadero style that formats following Embarcadero conventions.

The previous formatter had formatting settings inside the IDE Options, but for clang- format you can edit the configuration file or create a new one. Formatting settings are found in the *.clang-format files. The current configurations are inbuilt, but you can create a new configuration file in the \bin or your versioned RAD Studio AppData user folder (recommended), e.g.

C:\Users\YOU\AppData\Roaming\Embarcadero\BDS\22.0\

Information on how to write a clang-format file can be found here. You can base a file on a pre-existing configuration, including an inbuilt configuration, so making a format config that changes only one or two things is fast.

Files will be found by the IDE when next started and displayed as an option in the ‘Formatting style’ combo box. Edits to a config file will be applied every time formatting is invoked without needing to restart the IDE.

6.1.3.1 Preventing formatting Surround code you do not want formatted with comments as follows:

// clang-format off Code here will not be formatted // clang-format on

A comment can be in single-line format (//) or multi-line (/* */). Turning it off via a comment pauses formatting until an ‘on’ comment is found. These comments themselves will be formatted.

6.2 C++ / Delphi Compatibility

This release has seen a focus on smoothing the integration between Delphi and C++. We now have C++-compatible RTTI available for Delphi types; you can use make_shared on a Delphi type, and there are type conversions to assist in using Delphi types in C++.

6.2.1 C++-compatible RTTI for Delphi types In the past, C++ type information was not available for Delphi types; that is, accessing the result of typeid(delphi-type) where delphi-type is a type that comes from Pascal code, or is a Delphi-style class in C++, would result in an AV. Note that typeid returns a std::typeinfo for a type simply, or if it’s a polymorphic type for the most- derived type of that instance. typeid() now returns a std::typeinfo, and C++-compatible RTTI is generated for Delphi types.

6.2.2 Using smart pointers with Delphi classes

You can now use both std::make_unique and std::make_shared on a Delphi-style class (one defined in Delphi, or in C++ but inherited from one defined in Delphi.) This avoids having to write code like:

auto a = std::shared_ptr(new TObject());

where ‘new’ is bad C++ style, and you would normally want to use the make_shared method.

You can now write,

auto a = make_shared();

6.2.3 Other The Clang compiler now emits a warning when an interface does not derive from IUnknown.

6.2.4 Type conversions The RTL now includes helper methods for type conversions between Delphi types and C++ (and Delphi) strings. This includes conversions from TDateTime to string types, as well as being able to easily convert (assign) from a C++ string to a Delphi string, and use std::string_view on a Delphi string.

We’re very interested in your feedback on these changes.

6.2.4.1 Type conversions to and from strings The classic compiler performed some conversions from some Delphi types to string implicitly. This was incorrect by the C++ standard, and we have not mimicked that incorrect behavior in the Clang computer -- but it is very useful to be able to convert easily and so we have added methods to convert types in a C++ish way, following the example set by std::to_string.

There are now to_string() and from_string() methods for many types to convert to and from strings (UnicodeString, WideString and AnsiString, including templated by codepage), which you can use as follows, here for a Currency value:

String str; Currency curr; TFormatSettings fs;

to_string(str, curr, fs);

from_string(curr, str, fs);

These methods exist for the following types:

● Currency ● TDateTime ● 32 and 64-bit signed and unsigned integer types ● Floating point types (as Extended) ● Variants

6.2.4.2 Assign a C++ string to a Delphi string Direct C++ string to Delphi string assignment works through the string_view constructor:

String str;

std::string std_str("Hello World!"); str = std_str;

std::wstring std_wstr(L"abcdefghijklmnopqrstuvwxyz"); str = std_wstr;

std::u16string std_u16str(u"große Straße"); str = std_u16str;

std::u32string std_u32str(U"sehr kleine Straße"); str = std_u32str;

Or constructing an AnsiString:

AnsiString str;

std::u16string std_str(u"Hello World!"); str = std_str;

std::u32string std_str(U"Hello World!"); str = std_str;

std::wstring std_str(L"abcdefghijklmnopqrstuvwxyz"); str = std_str;

This means you no longer need to assign from the various string types by constructing using c_str().

6.2.4.3 Assign a Delphi string to a C++ string, or get a string_view of a Delphi string You should also be able to assign a C++ string from a Delphi string the same way, since you can get a string_view for a Delphi string:

ShortString str("Hello World!"); std::string_view view(str);

AnsiString str("Hello World!"); std::basic_string_view view(str);

UnicodeString str(L"СЛАДКОЕ"); std::basic_string_view view(str);

6.3 Exception handling

A large number of exception handling issues have been resolved. Please refer to the fix list at the end of this document.

6.4 Other

● You can now attach to a process using the C++ Win64 debugger ● An issue where batch compilation for a project ignored .c files has been resolved

7 VCL and FireMonkey Changes

In Olympus we have done (and are still doing) a large collection of small improvements to the VCL library, focused on removing some remaining XP legacy and inconsistencies with Windows 10 and improving core library features.

7.1 TRichEdit Component updated to RichEdit 4.1 (MSFTEDIT.dll)

In this release we updated the implementation of the VCL TRichEdit component to support a more recent version of the platform control. By doing so we have made a available directly in the VCL component many new platform features, including:

● Transparent richedit controls: When the new property Transparent is set to True the richedit becomes transparent -- its background is replaced by whatever is beneath it. When it is set to False, it behaves as normal, with its background filled with Color. ● URL detection, tooltips and link clicking (see below for more information) ● Spell checking: There is a new property SpellChecking; when set to True the richedit automatically offers native spell checking abilities (on Windows 8 or later) ● Subscript and superscript text attributes ● Background color ● Scroll position tracking (new property ScrollPosition: TPoint) ● Changing margins ● Other missing attributes (see below) ● EM_FormatRange support (see below)

Additionally, TDBRichEdit.Lines is now a public property

7.1.1 RichEdit URL detection RichEdit URL detection is made available with the following new features:

● EnableURLs turns on automatic URL detection in the richedit control. It recognises URLs with known protocols (e.g. http://google.com) or that start with www. (e.g. www.google.com). ● ShowURLHint, when set to True, causes tooltips to be automatically displayed when the mouse is over a URL. ● SetSelTextToFriendlyURL replaces the selected text (starting at position SelStart and running for SelLength characters) with a friendly hyperlink - any text you like (Text) that is a hyperlink to a specified URL (URL)

● When a URL in the richedit is clicked with the left or right mouse button the OnLinkClick event fires, passing the URL and an indication of which button was pressed.

7.1.2 RichEdit Text Attributes Changes TTextAttributes now has additional properties, and some properties have slightly different definitions (only in terms of their property indices so will not affect usage). Here are the full set of properties:

property BackColor: TColor read GetBackColor write SetBackColor; property Bold: Boolean index CFE_BOLD read GetStyleElement write SetStyleElement; property Charset: TFontCharset read GetCharset write SetCharset; property Color: TColor read GetColor write SetColor; property ConsistentAttributes: TConsistentAttributes read GetConsistentAttributes; property Disabled: Boolean index CFE_DISABLED read GetStyleElement write SetStyleElement; property Height: Integer read GetHeight write SetHeight; property Hidden: Boolean index CFE_HIDDEN read GetStyleElement write SetStyleElement; property Italic: Boolean index CFE_ITALIC read GetStyleElement write SetStyleElement; property Link: Boolean index CFE_LINK read GetStyleElement write SetStyleElement; property Name: TFontName read GetName write SetName; property Offset: Integer read GetOffset write SetOffset; property Pitch: TFontPitch read GetPitch write SetPitch; property Protected: Boolean index CFE_PROTECTED read GetStyleElement write SetStyleElement; property RevAuthor: Byte read GetRevAuthor write SetRevAuthor; property Size: Integer read GetSize write SetSize; property Strikeout: Boolean index CFE_STRIKEOUT read GetStyleElement write SetStyleElement; property Style: TFontStyles read GetStyle write SetStyle; property Subscript: TSubscriptType read GetSubscript write SetSubscript;

property Underline: Boolean index CFE_UNDERLINE read GetStyleElement write SetStyleElement;

The new ones are BackColor, Disabled, Hidden, Link, Offset, RevAuthor and Subscript.

TConsistentAttribute in Vcl.ComCtrls.pas now has a new member: caCharSet. This relates to the TTextAttributes.CharSet property.

There are also new types used by TParaAttributes: cpaAlignment, cpaNumbering, cpaFirstIndent, cpaLeftIndent, cpaRightIndent, cpaTabStops.

TParaAttributes has a new property, ConsistentAttributes

This operates similarly to TTextAttributes.ConsistentAttributes in that it returns consistent paragraph attributes from the current selection. The values are described as follows:

● cpaAlignment: Alignment is consistent in the selection ● cpaNumbering: Numbering is consistent in the selection ● cpaFirstIndent: FirstIndent is consistent in the selection ● cpaLeftIndent: LeftIndent is consistent in the selection ● cpaRightIndent: RightIndent is consistent in the selection ● cpaTabStops: Tab settings are consistent in the selection

Additionally, Vcl.ComCtrls.TTextAttributes now has 4 extra Boolean properties to complement Vcl.ComCtrls.TTextAttributes.Style, which allow the individual style attributes of bold, italic, strikeout and underline to be read or written independently:

● property Bold: Boolean ● property Italic: Boolean ● property Strikeout: Boolean ● property Underline: Boolean

7.1.3 RichEdit EM_FORMATRANGE TCustomRichEdit now has a new public method:

function RenderRange(RenderTarget: TCanvas; FormatTarget: TCanvas = nil; RangeStart: Integer = 0; RangeEnd: Integer = -1; MeasureOnly: Boolean = False): Integer;

This provides an alternative to the general purpose Print method allowing custom ranges of the rich edit content to be rendered to any specified TCanvas. The parameters are as follows:

● RenderTarget: a canvas representing the device to render to, if RenderRange is being used to send output to a device, so Printer.Canvas is typically used here, but might be something else if building a print preview window. ● FormatTarget: a canvas representing the target device to format for, so typically Printer.Canvas. If this parameter is nil (the default value) then it defaults to the same as RenderTarget. ● RangeStart: the character position index immediately preceding the first character in the range to be rendered by this call. The default value of 0 indicated the beginning of the richedit control's content. ● RangeEnd: the character position immediately following the last character in the range to be rendered by this call. The default value of -1 indicates the last character in the richedit control's content. ● MeasureOnly: if False (the default) then the text is rendered, if True the text is just measured.

7.2 VCL Modernization Work

7.2.1 New Default Font For VCL applications, the default font is now Segoe UI 9. The title font of the VCL styles is getting adapted to the same default font.

7.2.2 Memo and RichEdit Margins New property in TCustomMemo, published in TMemo, TDBMemo, TRichEdit, TDBRichEdit:

property EditMargins: TEditMargins read FEditMargins write SetEditMargins; where TEditMargins is a type whose public interface is:

TEditMargins = class(TPersistent) public procedure Assign(Source: TPersistent); override; property OnChange: TNotifyEvent read FOnChange write FOnChange; published property Left: TMarginSize read FLeft write SetLeftMargin default 0; property Right: TMarginSize read FRight write SetRightMargin default 0; property Auto: Boolean read FAuto write SetAutoMargin default False; end;

EditMargins.Left and EditMargins.Right allow you to set a specific left and/or right margin on a multiline edit control. EditMargins.Auto sets EditMargins.Left and EditMargins.Right to 0 and allows the control to set its own narrow margins based on its font.

However it should be noted that richedit controls do not respond effectively to EditMargins.Auto, simply setting their left margin to 0. It is currently unclear why this happens.

7.2.3 Radiogroup without frame In TCustomGroupBox we have this public property published in TGroupBox:

● ShowFrame controls whether the groupbox frame is drawn or not

● HeaderFont is the font used to render the group caption, as drawn in the top of the group frame. By default, it is the same as Font and any changes to Font are reflected by the same changes happening to HeaderFont

● DefaultHeaderFont defines the relationship between HeaderFont and Font. When HeaderFont is edited, DefaultHeaderFont becomes False and further changes to Font are not made to HeaderFont. Setting HeaderFont to True makes HeaderFont revert to mirroring Font

7.2.4 DropDownWidth for TComboBox There are two new properties in TCustomComboBox and descendants (public in the TCustomComboBox class, published in the TComboBox class):

property AutoDropDownWidth: Boolean read FAutoDropDownWidth write FAutoDropDownWidth default False; property DropDownWidth: Integer read GetDropDownWidth write SetDropDownWidth stored IsDropDownWidthStored;

● DropDownWidth allows you to customize the minimum width of the combobox's dropdown list. If anything less than the combobox width, then you will see no difference. Larger sizes allow the list to be wider than the combobox for wider strings. If the wider list might spill off the edge of the screen then the list is shifted so that the right list edge is below the combobox right edge and the extra width extends out to the left past the left edge of the combobox.

● AutoDropDownWidth when set to True causes the dropdown list width to be automatically set to as wide as the widest string in the combobox items.

7.2.5 TTreeView support for CheckBoxes TTreeNode defines these new properties: property Checked: Boolean read GetChecked write SetChecked; property CheckState: TNodeCheckState read GetCheckState write SetCheckState; where TNodeCheckState is:

TNodeCheckState = (ncsNone, ncsUnchecked, ncsChecked, ncsPartial, ncsDimmed, ncsExclusion);

Assuming checkboxes are enabled (see TCustomTreeView.CheckBoxes) the check state of a given node can be queried or set with CheckState. Checked is a shortcut property to either find if the check state is ncsChecked or not, or to set the check state to either ncsChecked or ncsUnchecked.

Note that if you try to set a check state that is not appropriate based on the current value of TCustomTreeView.CheckStyles, or is invalid thanks to TCustomTreeView.CheckableItems being False then an exception is raised.

TCustomTreeView defines these protected members: procedure DoCheckStateChanged(Node: TTreeNode; CheckState: TNodeCheckState); virtual; function DoCheckStateChanging(Node: TTreeNode; NewCheckState, OldCheckState: TNodeCheckState): Boolean; virtual; property CheckableItems: Boolean read FCheckableItems write SetCheckableItems default False; property CheckStyles: TCheckStyles read FCheckStyles write SetCheckStyles default []; property OnCheckStateChanged: TTVCheckStateChangedEvent read FOnCheckStateChanged write FOnCheckStateChanged; property OnCheckStateChanging: TTVCheckStateChangingEvent read FOnCheckStateChanging write FOnCheckStateChanging;

These of the above are published by TTreeView: property CheckableItems; property CheckStyles; property OnCheckStateChanged; property OnCheckStateChanging;

The above relies on these types:

TCheckStyle = (csPartial, csDimmed, csExclusion); TCheckStyles = set of TCheckStyle; TTVCheckStateChangedEvent = procedure(Sender: TCustomTreeView; Node: TTreeNode; CheckState: TNodeCheckState) of object; TTVCheckStateChangingEvent = procedure(Sender: TCustomTreeView; Node: TTreeNode; NewCheckState, OldCheckState: TNodeCheckState; var AllowChange: Boolean) of object;

When the CheckableItems property is set to True the treeview gets checkboxes against each node, where the checkbox state is available as a value of type TNodeCheckState given by TTreeNode.CheckState and defaults to ncsUnchecked. By default these are simple 2-state checkboxes, with states of ncsChecked and ncsUnchecked.

However, there are three optional extra states that can be introduced using the treeview's set property CheckStyles:

● csPartial (a small square in the checkbox) ● csDimmed (a dimmed checkmark) ● csExclusion (a cross)

You can select any combination that makes sense for your application and when a node checkbox is clicked sufficiently to yield one of these states they are represented by the TNodeCheckState values ncsPartial, ncsDimmed, and ncsExclusion.

When a checkbox is clicked and its state changes the component first fires the OnCheckStateChanging event, which is passed the old (current) and new check state and gives the opportunity to stop the check state change occurring through its AllowChange var parameter. Assuming the change is allowed then the OnCheckStateChanged event fires passing the new check state.

7.2.6 TWICImage multi frame support TWICImage multi frame support, there are 2 new properties in type TWICImage defined as FrameCount and FrameIndex.

You set FrameIndex to indicate the desired frame from a multi-frame image (such as a multi-frame TIFF file). When loading from the image file that frame is loaded if it exists or an EInvalidOperation exception is raised; FrameIndex defaults to 0, which is valid on images without multiple frames.

When a TWICImage loads a file (or, technically, loads a frame from a file), FrameCount will tell you how many frames are in the file.

These two properties together allow you to read all valid frames in a multi-frame image file.

7.2.7 New TLabelDBEdit component There is now a data-aware version of the TLabeldEdit VCL control. To implement it, the hierarchy of the related controls has changed:

● TCustomLabeledEdit ○ inherits from TCustomMaskEdit ○ new properties: Align, EditMask, etc. inherited from TCustomMaskEdit ● TDBEdit ○ inherits from TCustomLabeledEdit ● TDBLabeledEdit ○ new control that inherits from TDBEdit

Additionally, Olympus adds support for the TLabeledEdit control in the TFlowPanel and TGridPanel containers.

7.2.8 Error Messages improvements ● In case of an error creating a form from a stream, the error message now includes the form file name. ● The Exception Dialog has an extra “Copy” button to copy the error message to the clipboard (the copy operation was already working after selecting the text of the label, but it wasn’t intuitive)

7.2.9 Coolbar Chevron support Coolbar has Chevron support via a new Boolean property ShowChevron.

● When set to True this property helps ensure the user can access hidden buttons. In the case where a TCoolBand in a TCoolBar contains a TToolBar with Wrapable set to False, then if the band is shrunk so that 1 or more tools buttons on the TToolBar are either not visible or not completely visible a

chevron is drawn on the band. Clicking the chevron pops up a popup menu containing items representing all tool buttons that are partly visible or not.

7.2.10 NumberBox The TNumberBox class introduced in 10.4.2 has a few additional features:

● CurrencyFormat type is changed from Byte to TNumberBoxCurrencyFormat. ● There is a new ValueCurrency property. ● The DisplayFormat property is now published.

7.2.11 Threading safety improvement

In general, UI controls should be created in the main UI thread. If you create a VCL control in a background thread, the behavior is undefined and can lead to fairly obscure access violations.

For this reason, there is a new class property:

TControl.RaiseOnNonMainThreadUsage

When this property is True, the VCL will raise an exception in case a TWinControl window handle is created in a thread that’s not the main thread. This prevents issues when this is done by accident. In COM scenarios and other cases, the creation of a handle in a secondary thread might be legitimate and so it remains allowed.

7.2.12 VCL StyleUtils.inc converted to a regular unit The include file StyleUtils.inc has been converted to a regular unit, allowing developers (and component vendors) to better integrate their code with VCL styles support. The previous include file, in fact, defined private types generally impossible to modify and extend, unlike the new unit.

Warning: While we agreed to move the code to a unit, making some data types public and accessible, we reserve the right to make changes to this style API and cannot guarantee the same level of compatibility with external code that the VCL and RTL libraries generally provide.

Attention: While the new DCU files are being delivered, the source code is not part of the installation. We’ll address this issue.

7.2.13 Smaller Changes

● Common dialogs how expose the properties EncodingIndex and ShowEncodingList (which controls whether the dropdown encoding list is enabled and therefore available for use)

● OnTracking event for TTrackbar (triggered when the thumb position on a trackbar is changing).

● Options to skip disabled in TPageControl.FindNextPage with an additional CheckTabEnabled parameter.

● TButtonCategory has a VisibleGutter property.

● TDateTimePicker and TRichEdit display properly when not enabled.

● TScrollBox, in this release, automatically supports the mouse wheel -- notice this change might affect the behavior of existing applications in unwanted ways, as the new default is to activate mouse wheel scrolling for controls without the focus.

● VCL function ScaleImage supports Alpha Channel.

● TVirtualImageList.Images has a proper property setter.

● TTreeNode offers support for nsDropHilited state.

● Default form size is now bigger.

● SetSelText and SetSelTextBuf offer the option not to reset the Undo buffer.

○ This is managed by a new property CanUndoSelText. It is False by default, which maintains backwards compatibility. If set to True it allows Undo to be called (or an Undo operation to be invoked with the UI) to undo a change made with calls to SetSelText or SetSelTextBuf or by assignments to the SelText property.

● Some small TEdgeBrowser improvements.

● TCustomTitleBarPanel now has TitleButtonClose, TitleButtonRestore, TitleButtonMin properties, and a OnUpdateTitlebarButtons event.

● TDateTimePicker allows changing both date and time together in UI

● A TPngImage object handles Assign to and from a TWICImage object

● TWinControl now supports LockDrawing and UnlockDrawing, triggering the execution of the WM_SETREDRAW Windows message:

○ Method TWinControl.LockDrawing disables control updating

○ Method TWinControl.UnlockDrawing enables control updating

○ property TWinControl.IsDrawingLocked returns True if LockDrawing was called (and UnlockDrawing was not called)

○ property TWinControl.RedrawDisabled returns True when the Win32 control drawing is disabled

7.3 FireMonkey

For FireMonkey we have focused on some core refactoring, with particular focus on desktop and Windows in particular.

7.3.1 Better FMX Windows and desktop integration ● Platform services for macOS and Windows refactored into separate units ○ IFMXMultiDisplayService, IFMXScreenService, IFMXDeviceMetricsService, IFMXFullScreenWindowService ● Refactoring of: ○ IFMXSaveStateService ○ IFMXDeviceService ○ IFMXVirtualKeyboardService ○ IFMXTimerService ○ IFMXLoggingService ○ IFMXMenuService ● Extended IFMXMultiDisplayService and TDisplay. ● Extracted all metrics related services into FMX.Platform.Metrics.* units. ● Constraints size for forms.

7.3.2 FireMonkey Windows High-DPI improvements Screen service in FMX used to work in DP on all platforms except Windows. This means TForm.Left, Top, Width and Height works in DP on all platforms except Windows. TForm.Top, TForm.Left in a PX on Windows at the same time TForm.Width and TForm.Height works in DP. So, some properties like Bounds returned a really wrong and strange result (position in px, size in dp in one entity).

The same is about Screen entity, it worked in DP on all platforms except Windows. As a result, the logic that is tied to the positioning of forms completely does not work correctly on Windows: This is all related to the popup form display also, styled border and etc. (there were a set of reports about issues of working popups, forms, form styled border on HiDPI screens).

So for fixing these issues, we standardized the work of the screen service and form positioning. Starting with 10.4.2 it works the same as for other platforms. So these changes were intentional. Now we have further extended this change.

Specific changes for this area:

● Switch from pixels to device independent units (PX to DP), extend IFMXMultiDisplayService ● Fixes to many related issues with features, dragging, positioning… ● Refactoring of TWindowBorderWin ● TControl has new methods for coordinate conversions: ○ ScreenToLocal/LocalToScreen ○ ConvertLocalPointFrom/ConvertLocalPointTo

7.3.3 Google Play Billing Library Version 4 The Olympus beta offers support for the latest version of Google’s Billing API, an update that’s becoming mandatory later this year for Play Store apps (the final deadline is November ‘21).

The new API is integrated seamlessly with the FMX library and your code should adapt easily to the new API.

7.3.4 Android 30 API support Android API 30 support includes the following changes

● Support to target Android API 30 (a Google Play Store requirement for 2021) ● We also migrated from the old “Support Library” libraries to the new “AndroidX” libraries

Also, for Android, RAD Studio now supports the “multidex” feature (which allows your app to generate multiple “classes.dex” files) and uses the newer “D8” DEX compiler instead of the old “DX” one to compile Java bytecode into DEX one.

The new releases include a different set of Java libraries and this makes old projects incompatible. When you open an Android project build with an older version of RAD Studio you need to:

● Navigate to the Projects dockable window. ● Select Android 32-bit or Android 64-bit as the active target platform. ● Right-click on the Libraries node. ● Click on the Revert System Files to Default menu item.

7.3.5 Additional Improvements ● Firemonkey Accessibility Pack is now integrated in the core product (rather than being a separate download) ● Improved Z-Order management for combinations of styles and platform controls ● Removed old deprecated non-scoped enumerated values (that is the FMX Helper classes added to support deprecated enumerations in 2014) ● Support for file upload in TWebBrowser on the Android platform

8 RTL and Data

There are many improvements in the core RAD Studio libraries. Here we are providing a summary of the key changes across RTL, FireDAC, HTTP and REST client libraries and more.

8.1 Platform Identifiers

RTL adds a new platform identifier, pidOSXArm64 for the macOS/Arm64 platform.

Also, the existing pidAndroid32Arm and pidAndroid64Arm identifiers are now obsolete. These are replaced by the new pidAndroidArm32 and pidAndroidArm64, as we have normalized all platform names:

All platform related identifiers use the same format and order of the compilers:

8.2 RTL: TZipFile

We have focused on ZIP files (that is, the TZipFile class of the RTL) quality, improvements, and optimizations. Among others we addressed the following requests:

● TZipHeader has a GetFileName method ● Added support for Zip64 ● Added a method to remove a file in TZipFile ● TZipFile.IsValid() now accepts a stream parameter ● System.Zip improved to work with files larger in size than 4 GB

8.3 RTL large data structures improvements

We have made a few improvements in the use of proper data types for larger memory structures under 64-bit compilers. For example, TMemoryStream in 64-bit supports data structures larger than 2 GB.

Related to this, we added the new method TThread.GetTickCount64 (while the existing TThread.GetTickCount, returning a 32-bit value, remains in the RTL for compatibility).

8.4 Record Helper for TDateTime

There is a new record helper for TDateTime, which includes a “UTC Now” function (not available in the original Date RTL), actually called NowUTC.

The helper is in the System.DateUtils unit and includes the following (mostly self- explanatory) long list of methods:

● Now, NowUTC, Today, Yesterday, Tomorrow ● GetDate, GetTime, ● IsInLeapYear, IsPM, IsAM, IsToday, IsSameDay

● WeeksInYear, DaysInYear, DaysInMonth ● GetYear, GetMonth, GetWeek, GetDay, GetHour, GetMinute, GetSecond, GetMilliSecond ● StartOfTheYear, EndOfTheYear, StartOfTheMonth, EndOfTheMonth, StartOfTheWeek, EndOfTheWeek, StartOfTheDay, EndOfTheDay ● WeekOfTheYear, DayOfTheYear, HourOfTheYear, MinuteOfTheYear, SecondOfTheYear, MilliSecondOfTheYear, WeekOfTheMonth, DayOfTheMonth, HourOfTheMonth, MinuteOfTheMonth, SecondOfTheMonth, MilliSecondOfTheMonth, DayOfTheWeek, HourOfTheWeek, MinuteOfTheWeek, SecondOfTheWeek, MilliSecondOfTheWeek, MinuteOfTheDay, SecondOfTheDay, MilliSecondOfTheDay, SecondOfTheHour, MilliSecondOfTheHour, MilliSecondOfTheMinute ● WithinPastYears, WithinPastMonths, WithinPastWeeks, WithinPastDays, WithinPastHours, WithinPastMinutes, WithinPastSeconds, WithinPastMilliSeconds ● YearsBetween, MonthsBetween, WeeksBetween, DaysBetween, HoursBetween, MinutesBetween, SecondsBetween, MilliSecondsBetween ● DateTimeInRange, DateInRange, TimeInRange ● YearSpan, MonthSpan, WeekSpan, DaySpan, HourSpan, MinuteSpan, SecondSpan, MilliSecondSpan ● IncYear, IncMonth, IncWeek, IncDay, IncHour, IncMinute, IncSecond, IncMilliSecond, AddYear, AddMonth, AddWeek, AddDay, AddHour, AddMinute, AddSecond, AddMilliSecond ● Encode, Decode, EncodeWeek, DecodeWeek, EncodeDay, DecodeDay, EncodeMonthWeek, DecodeMonthWeek, TryEncode, TryEncodeWeek, TryEncodeDay, TryEncodeMonthWeek ● SetYear, SetMonth, SetDay, SetHour, SetMinute, SetSecond, SetMilliSecond, SetDate, SetTime, SetDateTime ● CompareDateTime, SameDateTime, CompareDate, SameDate, CompareTime, SameTime

● NthDayOfWeek, DecodeDayOfWeekInMonth, EncodeDayOfWeekInMonth, TryEncodeDayOfWeekInMonth ● ToJulianDate, SetJulianDate, TrySetJulianDate, ToModifiedJulianDate, SetModifiedJulianDate, TrySetModifiedJulianDate ● ToUnix, SetUnix ● ToMilliseconds, TimeToMilliseconds ● SetISO8601, TrySetISO8601, ToISO8601, SetHttpDate ● ToString, Format

The helper also introduces the following properties for TDateTime: Day, Month, Year, Hour, Minute, Second.

8.5 Record Helper for TCurrency

This release also introduces a helper for the TCurrency data type in Delphi, TCurrencyHelper, similar to the TDoubleHelper. The helper has the methods ToString, Frac, Ceil, Floor and Trunc. It also defined class functions Size, ToString, Parse, and TryParse.

8.6 Bluetooth and BLE Improvements

We have focused on improving quality in this area for all platforms making sure all the core demos work as expected after fixing several open issues. Improvements include both classic Bluetooth and Bluetooth LE and most platforms, with particular focus on Windows 10 and Android (but also iOS and macOS). Improvements also include Beacons support.

The specific list of Bluetooth issues addressed is in the bug list fix below.

8.7 Additional RTL Enhancements

8.7.1 Generic Collections Improvements When using multiple generic types, some generic collections used to have TKey and TValue as symbolic names for the generic types. Now this is confusing as TValue is a

specific type in the RTL. To avoid any confusion the symbolic names have been changed. There is no effect to existing code, as the symbolic names are replaced with concrete types when the generic types are instantiated.

Additionally, there are few additional constructors for collection classes, that take as parameters an array of values, including:

procedure DoCheckStateChanged(Node: TTreeNode; CheckState: TNodeCheckState);

virtual;

constructor TList.Create(const Values: array of T); constructor TDictionary.Create(const AItems: array of TPair);

The implementation of TDictionary Capacity, GrowThreshold and hashing has been improved, with a better balance of performance / memory usage / minimal collisions.

The internal implementation class TListHelper has been removed in favor of using a strongly typed field TArray, updating all related streaming and data mapping code.

8.7.2 RTTI Open array support to RTTI: allows invoking methods with an open array parameter via RTTI and also supports open array arguments in TVirtualMethodInterceptor.

TValue adds specific support for TDateTime. Also, TValue and Variant type interchange has been improved.

8.7.3 PPL Made the PPL Thread pool statistics easier to access, that is, TThreadPoolStats.Get method is now public

8.7.4 Streams New TPointerStream class, allows reading and writing in-memory data using the TStream interface, by indicating a pointer location and a size.

TStream.CopyFrom doesn’t require the size, which might be unknown. The method has also been optimized when Count is large (up to 400% improvement).

8.7.5 Dates to String Conversion Dates to strings and reverse conversions have been improved (including a few long- standing issues). Worth to note, that now StrToDate:

● strictly follows to date format string ● supports date formats with month and day names ● supports date formats with arbitrary text inside

Also improves TFormatSettings date/time related properties initialization and unifies the representation on all platforms.

8.7.6 Create a Interface Instance There is a new System.Generics.Defaults._MakeInterfaceInstance that allows creating an interface instance, where all interface methods are represented by anonymous methods.

8.7.7 TNoRefCountObject The new class System.TNoRefCountObject is a non-reference-counted IInterface implementation (replacing the old and oddly named TSingletonObject)

8.7.8 Optimizations and Other ● Optimized _FinalizeRecord and _FinalizeArray ● The legacy TDatamodule.OldCreateOrder property has been removed and always default to true. In case the property is present in a form description file, it is ignored (but won’t generate an error). The legacy property was used for

compatibility with an older creation order logic, in the early versions of Delphi a long time ago. ● Improved Pascal System.Pos ● TArray.BinarySearch optimization ● Added overloads of TList.Sort( ..., Index, Count ) ● Added System.IOUtils.TFile.Size ● TObject performance fixes for ClassParent and InitInstance ● Some improvements to System.IOUtils.TPath ● RTL support for a system path longer than 260 chars, if supported by the operating system (like on recent versions of Windows) ● Added class property TThread.OnSynchronize ● The EInOutError and EInOutArgumentException messages now include the path and have a Path field.

Improved performance of:

● _UInt32ToHexString and _UInt64ToHexString ● Parse and TryParse for TSingleHelper and TDoubleHelper

The TGUID data structure is now defined only in System.pas (there was a duplicate definition in WinAPI.Ole2.pas)

8.7.9 JSON ● Moved ParseJSONValue() from TJSONObject to TJSONValue ● Added an overloaded TJSONObject.AddPair for an Integer

8.7.10 UTF8ToString Changes The UTF8ToString overload that accepts an array of AnsiChar has been removed and UTF8ToString(array of Byte) deprecated. The removed function is:

UTF8ToString(const S: _PAnsiChr)

The old implementation of that API ignored the length of the array and instead relied on a NULL terminator. Simply changing the implementation would have been

dangerous, as we discovered that there was quite a bit of code that relied on the existing behavior.

STATIC ARRAY

If you have code that invokes UTF8ToString with a static array of AnsiChar, like the following, that code will work as it worked in previous versions:

var Buffer: array[0..MAXPHAT] of AnsiChar; begin ... UTF8ToString(Buffer);

DYNAMIC ARRAY

If you have code that invokes UTF8ToString with a dynamic array of AnsiChar, like this, that code will no longer compile:

var Buffer: array of AnsiChar; // Or TArray begin ... UTF8ToString(Buffer);

To remedy you must switch to one of the following:

1. Cast the array to PAnsiChar This keeps the older behavior where the API relies on a NULL terminator and ignores the length of the array.

var

Buffer: array of AnsiChar; // Or TArray

begin

...

UTF8ToString(PAnsiChar(Buffer));

2. Use UTF8ArrayToString This uses the new UTF8ArrayToString API that ignores NULL terminators and converts all characters in the dynamic array.

var

Buffer: array of AnsiChar; // Or TArray

begin

...

UTF8ArrayToString(Buffer);

8.8 FireDAC

● PostgreSQL driver supports PostgreSQL up to v 13, including support PostgreSQL Stored Procedures ● Official support for Oracle 19c and for 128-character parameter names for Oracle Stored Procedures. ● Extended TFDSortOption with soDigitsAsNumbers, matching the similar TCompareOption in System.SysUtils. ● Firedac Monitor UI improvements. ● Improved Firebird driver to look for the driver in VendorHome and not in the /bin subfolder (which was correct for older versions of Firebird)

8.9 Internet, HTTP and REST Client Libraries

● Timeout mechanism for Backend and EMS client components:

○ The TEMSProvider, TKinveyProvider, TParseProvider classes have 2 new properties: ConnectTimeout and ReadTimeout

○ TEMSApi.TConnectionInfo, TParseApi.TConnectionInfo, TKinveyApi.TConnectionInfo: have variables ConnectTimeout and ReadTimeout

○ TDSRestConnection also surfaces ConnectionTimeOut

● Added Windows support for HTTP / 2

○ New property THttpClient.ProtocolVersion

○ New property TNetHttpClient.ProtocolVersion

● New TBase64URLEncoding encoding and TNetEncoding.Base64URL property

● Switched from gethostbyname to getaddrinfo in the entire RTL, for all platforms.

● New TCertificate.PublicKey, which contains public key modulus

● ContentType now is of string type, not enum. This allows you to use any one content type string. Also, new CustomContentType in RestRequest

● Support for TLS 1.3 in TNetHTTPClient for Windows

● Multiple improvements to TSocket

● A new component TRESTRequestDataSetAdapter simplifies uploading TDataSet (eg, TFDMemTable) data to a server via JSON. It is a companion for the TRESTResponseDataSetAdapter REST component on the server side.

● The TRestClient component surfaces the SecureFailureReasons property of the underlying HTTPClient component

● In the Vcl.Styles unit, the TCustomStyle class FCustomElements and FSource are now declared in the protected section.

8.10 Internet Server Technologies

WebBroker

ISAPI DLL threads have a configurable StackSize, using the variable Web.Win.ISAPIThreadPool.StackSize.

Significantly improved WebBroker performance when sending/streaming files larger than 2 GB (MaxInt).

RAD Server

Multipart/form-data support for RAD Server

DataSnap

DataSnap: The REST URI is now configurable using a new mechanism, based on a TDSMethodMapEvent event

9 Installer Changes

The Olympus installer has several changes worth noticing.

● The minimal installer has been updated to display properly on High DPI screens. The radio buttons and checkboxes should be properly visible. ● The minimal installer offers a language selection option, rather than relying on the OS detection like in the past.

This gives a smoother experience to anyone on a German, French, or Japanese version of Windows who wishes to install the English version of RAD Studio.

Additionally, the platform selection will require the selected language: a discrepancy among the two options could lead to a mixed language IDE, something we’d want to avoid.

● A new Catalog Repository folder selection for installation files allows you to keep the fairly large installation files in a custom location, other than under the public documents folder:

● The installation is now faster. The download of complex features happens by downloading multiple files in parallel rather than in sequence. There is parallelism also between download and extraction of compressed files, while the installation of the features happens in sequence. The information displayed during the installation has been modified accordingly, and the odd “feature names” visible in 10.4.x have been removed and replaced by the number of the download file for each feature.

Attention: The progress bar during the feature installation is not working properly in this build. Let us know any other installation anomaly you notice or any scenario in which installation doesn’t complete.
