Install Alcinoe
If you don’t plan to use any Alcinoe visual components at design time, then you don’t need to install anything, just add {alcinoe_rootdir}\source in the search path of your project.

If you plan to use visual components at design time then you need to install the BPL. Launch Delphi and go in component > Install Packages… > and choose the BPL located in {alcinoe_rootdir}\lib\bpl\alcinoe\Win32\sydney\Alcinoe_sydney.bpl (if you are in delphi Sydney else choose the directory that corresponds to your Delphi version). You still need to add in your search path {alcinoe_rootdir}\source

Alcinoe also improves a little the original Delphi source codes. In this way, you will need to go in {alcinoe_rootdir}\embarcadero\sydney\10_4_2 and run update.bat to retrieve and patch the original Delphi source code. The batch file assumes that the original source code is located in “c:\Program Files (x86)\Embarcadero\Studio\21.0\source” and that you have GIT in your path. After the batch is copied and patched the Delphi source code will need to include this source code in your project search path.

To finish more and more libraries use Java 1.8 features (like webRTC, exoplayer, etc.). In this way, we must do desugaring (Desugaring allows you to use these features on older devices by replacing new bytecodes and language APIs with older ones during the build process). With d8.bat (replacement of dx.bat), desugaring is turned on by default. So you can now use most of the latest language changes while targeting older devices. Waiting for Embarcadero swap to D8.bat, we must make DX.bat a “proxy” to D8.bat. For this just replace your original DX.bat (mine is located in c:\SDKs\android\build-tools\30.0.3\d8.bat) by the one located in {alcinoe_rootdir}\tools\D8Proxy\dx.bat. more details here: https://quality.embarcadero.com/browse/RSP-24155

Full OpenGL video player for FireMonkey
ALVideoPlayer will render a video to a TEXTURE. This is really important because you can fully integrate the video in the Delphi form and you can place any controls you want on the top of it as it’s support Z-ORDER. Official Delphi video player are just native video player window on the top of the form and thus not support Z-ORDER.

Under android I use ExoPlayer. ExoPlayer supports features like Dynamic adaptive streaming over HTTP (DASH), HLS, SmoothStreaming and Common Encryption, which are not supported by MediaPlayer. It’s designed to be easy to customize and extend. Under iOS I use AVPlayer with support also HLS like ExoPlayer does

WebRTC Delphi wrapper
WebRTC (Web Real-Time Communications) is a technology which enables Web applications and sites to capture and optionally stream audio and/or video media, as well as to exchange arbitrary data between browsers and mobile applications without requiring an intermediary. The set of standards that comprises WebRTC makes it possible to share data and perform teleconferencing peer-to-peer, without requiring that the user installs plug-ins or any other third-party software.

TALWebRTC component makes it easy to add video and audio chat into your applications, which opens up a whole new world of interactivity

Firemonkey native iOS/Android TEdit and TMemo
The spirit is to mix FireMonkey control with native platform control when the functionality on such control starts to be very hard to implement (like webbrowser, edit, memo, datepicker, etc.). But it’s not to make several distinct forms for several platforms like offer for example http://www.turbococoa.com/ (but this option is also a good alternative in some way, it’s up to you to decide)

In Delphi (berlin) their is already IOS platform control that was quite well implemented but close to none android platform control and so I start to build native android/iOS controls like TEdit/TMemo. These control work mostly like some windows that are placed on The top of the form (so off course no z-order with FireMonkey control)

The fact
Painting of FireMonkey controls can be sometimes slow, or say differently, not sufficiently fast for a fluid scrolling. For example if you simply look the basic TRectangle with round corners, the paint procedure can take around 3ms! So if you have around 20 visible TRectangles on your screen, then it’s will cost you around 60ms to repaint the full screen (and normally you don’t have only TRectangle, you also have TLabel, TCheckbox, etc..). After it’s just math, take 100ms to repaint the screen, so you can only do around 10 frames per seconds (in reality you will have much less even) so the scrolling can’t be fluid 🙁

The solution
I didn’t want to rebuild the FireMonkey controls, it’s a too huge job for me, and instead I try to find an intermediate solution. This what I find by adding “double-buffered” property to the FireMonkey controls. So instead to repaint and repaint (and repaint) the controls for every single pixels move of the scrollbox, I first paint the control on a “buffer” that I store directly in the GPU memory (through TTexture), and when the system asks me to repaint the controls instead of calling again the paint algorithm I simply redraw the buffer TTexture.

The results
As I say before it’s took 3ms just to paint a simple TRectangle with round corners. With my double-buffered property it’s take now around 0.1ms! So now the scroll looks much more fluid!

OpenGL draw => Replaced by native iOS/android draw
Most of the basic shape (like TRectangle, TCircle, etc.) use openGL to draw. it’s not very efficient, for example to draw a circle under openGL you will in fact draw 50 triangles. This result often in poor quality : https://quality.embarcadero.com/browse/RSP-15206 For roundrect it’s even worse because you must first calculate the path and then later draw it (much more slow than TCircle)

Other problem is all of these draw depend of Form.quality. if you set form.quality to highquality then everything you will do on the canvas will be multisample like drawing an image for example and that could be problematic because the image will be anti-aliased. if you set form.quality to highperformance then the draw will be very rough (no anti aliasing).

To resolve this, I build the buffer of my control using NATIVE ANDROID/IOS API. In this way we will have a high quality draw at also a high speed without being dependent of the form.quality

Json Parser
TALJsonDocument is a Delphi parser/writer for JSON / BSON data format. it’s support DOM and SAX parser (Note a better name could be SAJ for Simple API for JSON instead of SAX for Simple API for XML but as the concept of SAX is well know I keep this name), support BSON format, and use a similar syntax than TALXMLDocument / TXMLDocument. TALJsonDocument can also export Json / Bson data in TALStringList.

When it deals with parsing some (textual) content, two directions are usually envisaged. In the JSON world, you have usually to make a choice between:

A DOM parser, which creates an in-memory tree structure of objects mapping the JSON content;
A SAX parser, which reads the JSON content, then call pre-defined events for each JSON content element.
In fact, DOM parsers use internally a SAX parser to read the JSON content. Therefore, with the overhead of object creation and their property initialization, DOM parsers are typically three to five times slower than SAX (and use much much more memory to store all the nodes). But, DOM parsers are much more powerful for handling the data: as soon as it’s mapped in native objects, code can access with no time to any given node, whereas a SAX-based access will have to read again the whole JSON content.

Most JSON parser available in Delphi uses a DOM-like approach. For instance, the DBXJSON unit included since Delphi 2010 or the SuperObject library create a class instance mapping each JSON node. In order to achieve best speed, TALJsonDocument implements DOM parser and also a SAX parser.

TALJsonDocument can also support comments inside the JSON source that is an extension to the JSON specifications

TALJsonDocument syntax is very similar to TALXMLdocument / TXMLDocument

TALJsonDocument is available in 2 variants: TALJsonDocument that is made on the top of ansiString (so UTF-8) and TALJsonDocumentU that is made on the top of unicode string (so UTF-16)

Example :

{
_id: 1, // comments
name: { first: “John”, last: “Backus” },
birth: new Date(‘1999-10-21T21:04:54.234Z’),
contribs: [ “Fortran”, “ALGOL”, “Backus-Naur Form”, “FP” ],
awards: [
{ award: “National Medal of Science”,
year: 1975,
by: “National Science Foundation” },
{ award: “Turing Award”,
year: 1977,
by: “ACM” }
],
spouse: “”,
address: {},
phones: []
}
To access the document nodes :

MyJsonDoc.loadFromJson(AJsonStr, False);
MyJsonDoc.ParseOptions := [poAllowComments]; // to allow comments inside the JSON source
MyJsonDoc.childnodes[‘_id’].int32;
MyJsonDoc.childnodes[‘name’].childnodes[‘first’].text;
MyJsonDoc.childnodes[‘name’].childnodes[‘last’].text;
MyJsonDoc.childnodes[‘birth’].datetime;
for i := 0 to MyJsonDoc.childnodes[‘contribs’].ChildNodes.count – 1 do
MyJsonDoc.childnodes[‘contribs’].childnodes[i].text;
for i := 0 to MyJsonDoc.childnodes[‘awards’].ChildNodes.count – 1 do begin
MyJsonDoc.childnodes[‘awards’].childnodes[i].childnodes[‘award’].text;
MyJsonDoc.childnodes[‘awards’].childnodes[i].childnodes[‘year’].text;
MyJsonDoc.childnodes[‘awards’].childnodes[i].childnodes[‘by’].text;
end;
Or if you are not sure of the existence of the nodes before to access them or you don’t want to check it you can also do :

MyJsonDoc.GetChildNodeValueInt32(‘_id’, 0{default if node not exists});
MyJsonDoc.GetChildNodeValueText([‘name’,’first’], ”{default if node not exists});
MyJsonDoc.GetChildNodeValueDateTime(‘birth’, Now{default if node not exists});
To create the document nodes :

MyJsonDoc.addchild(‘_id’).int32 := 1;
with MyJsonDoc.addchild(‘name’, ntObject) do begin
addchild(‘first’).text := ‘John’;
addchild(‘last’).text := ‘Backus’;
end;
MyJsonDoc.addchild(‘birth’).dateTime := Now;
with MyJsonDoc.addchild(‘contribs’, ntArray) do begin
addchild.text := ‘Fortran’;
addchild.text := ‘ALGOL’;
addchild.text := ‘Backus-Naur Form’;
addchild.text := ‘FP’;
end;
with MyJsonDoc.addchild(‘awards’, ntArray) do begin
with addchild(ntObject) do begin
addchild(‘award’).text := ‘National Medal of Science’;
addchild(‘year’).int32 := 1975;
addchild(‘by’).text := ‘National Science Foundation’;
end;
with addchild(ntObject) do begin
addchild(‘award’).text := ‘Turing Award’;
addchild(‘year’).int32 := 1977;
addchild(‘by’).text := ‘ACM’;
end;
end;
MyJsonDoc.addchild(‘spouse’);
MyJsonDoc.addchild(‘address’, ntObject);
MyJsonDoc.addchild(‘phones’, ntArray);
You can also create/update nodes like this :

MyJsonDoc.SetChildNodeValueInt32(‘_id’, 0);
MyJsonDoc.SetChildNodeValueText([‘name’,’first’], ‘John’);
MyJsonDoc.SetChildNodeValueDateTime(‘birth’, Now);
To load and save from BSON :

MyJsonDoc.LoadFromFile(aBSONFileName, False{saxMode}, True{BSON});
MyJsonDoc.SaveToFile(aBSONFileName, False{saxMode}, True{BSON});
To parse an JSON document in Sax Mode :

MyJsonDoc.onParseText := procedure (Sender: TObject;
const Path: AnsiString;
const name: AnsiString;
const Args: array of const;
NodeSubType: TALJSONNodeSubType)
begin
case NodeSubType of
nstFloat: Writeln(Path + ‘=’ + ALFloatToStr(Args[0].VExtended^, ALDefaultFormatSettings));
nstText: Writeln(Path + ‘=’ + ansiString(Args[0].VAnsiString));
nstObjectID: Writeln(Path + ‘=’ + ‘ObjectId(“‘+ALBinToHex(ansiString(Args[0].VAnsiString))+'”)’);
nstBoolean: Writeln(Path + ‘=’ + ALBoolToStr(Args[0].VBoolean,’true’,’false’));
nstDateTime: Writeln(Path + ‘=’ + ALFormatDateTime(”’ISODate(“”yyyy”-”mm”-”dd”T”hh”:”nn”:”ss”.”zzz”Z”)”’, Args[0].VExtended^, ALDefaultFormatSettings));
nstNull: Writeln(Path + ‘=’ + ‘null’);
nstRegEx: Writeln(Path + ‘=’ + ansiString(Args[0].VAnsiString));
nstBinary: Writeln(Path + ‘=’ + ‘BinData(‘+inttostr(Args[1].VInteger)+’, “‘+ansiString(ALBase64EncodeStringNoCRLF(ansiString(Args[0].VAnsiString)))+'”)’);
nstJavascript: Writeln(Path + ‘=’ + ansiString(Args[0].VAnsiString));
nstInt32: Writeln(Path + ‘=’ + ‘NumberInt(‘+inttostr(Args[0].VInteger)+’)’);
nstTimestamp: Writeln(Path + ‘=’ + ‘Timestamp(‘+inttostr(int64(cardinal(Args[0].VInteger)))+’, ‘+inttostr(int64(cardinal(Args[1].VInteger)))+’)’);
nstInt64: Writeln(Path + ‘=’ + ‘NumberLong(‘+inttostr(Args[0].VInt64^)+’)’);
end;
end;
MyJsonDoc.LoadFromJSON(AJsonStr, true{saxMode});
ImageMagick wrapper for Delphi
Use ImageMagick® to create, edit, compose, or convert bitmap images. It can read and write images in a variety of formats (over 200) including PNG, JPEG, GIF, HEIC, TIFF, DPX, EXR, WebP, Postscript, PDF, and SVG. Use ImageMagick to resize, flip, mirror, rotate, distort, shear and transform images, adjust image colors, apply various special effects, or draw text, lines, polygons, ellipses and Bézier curves.

Example :

var aWand: PMagickWand;
begin

//Create the ImageMagick Library
alCreateImageMagickLibrary({alcinoe_rootdir} + ‘\lib\dll\imagemagick\win32\imagemagick’, min(2, System.CPUCount){aThreadLimit});
try

//create the wand pointer
aWand := ALImageMagickLib.NewMagickWand;
try

//load the image
if ALImageMagickLib.MagickReadImage(aWand, pansiChar(aInputFilename)) <> MagickTrue then RaiseLastMagickWandError(aWand);

//Set the compression quality
if ALImageMagickLib.MagickSetImageCompressionQuality(aWand,80) <> MagickTrue then RaiseLastMagickWandError(aWand);

//autorate the image
if ALImageMagickLib.MagickAutoOrientImage(aWand) <> MagickTrue then RaiseLastMagickWandError(aWand);

//Resize the image using the Lanczos filter
if ALImageMagickLib.MagickResizeImage(aWand, 640, 480, LanczosFilter) <> MagickTrue then RaiseLastMagickWandError(aWand);

//save the image
ALImageMagickLib.MagickWriteImage(aWand, pansiChar(aOutputFilename));

finally
ALImageMagickLib.DestroyMagickWand(aWand);
end;

finally
alFreeImageMagickLibrary;
end;

end;

MongoDb client
Delphi Client for MongoDB database. A Delphi driver (with connection pool) to access a mongoDB server. a connection pool is a cache of database connections maintained so that the connections can be reused when future requests to the database are required. In connection pooling, after a connection is created, it is placed in the pool and it is used over again so that a new connection does not have to be established. If all the connections are being used, a new connection is made and is added to the pool. Connection pooling also cuts down on the amount of time a user must wait to establish a connection to the database.

Example :

aJSONDoc := TALJSONDocument.create;
aMongoDBClient := TAlMongoDBClient.create;
try
aMongoDBClient.Connect(”, 0);
aMongoDBClient.SelectData(‘test.exemple’,
‘{fieldA:123}’, // the query
‘{fieldA:1, fieldB:1}’, // the return fields selector
aJSONDoc.node);
aMongoDBClient.disconnect;
for i := 0 to aJSONDoc.node.childnodes.count – 1 do
with aJSONDoc.node.childnodes[i] do
writeln(aJSONDoc.node.childnodes[i].nodename + ‘=’ + aJSONDoc.node.childnodes[i].text)
finally
aMongoDBClient.free;
aJSONDoc.free;
end;
Example with connection pool :

aMongoDBConnectionPoolClient := TAlMongoDBConnectionPoolClient.create(aDBHost, aDBPort);
try

::Thread1::
aMongoDBConnectionPoolClient.SelectData(‘test.example’,
‘{fieldA:123}’, // the query
‘{fieldA:1, fieldB:1}’, // the return fields selector
aLocalVarJSONDOC.node);

::Thread2::
aMongoDBConnectionPoolClient.SelectData(‘test.example’,
‘{fieldA:999}’, // the query
‘{fieldA:1, fieldB:1}’, // the return fields selector
aLocalVarJSONDOC.node);

finally
aMongoDBClient.free;
end;
Example tail monitoring :

aMongoDBTailMonitoringThread := TAlMongoDBTailMonitoringThread.Create(
aDBHost,
aDBPort,
‘test.cappedCollectionExemple’
‘{}’, // the query
‘{fieldA:1, fieldB:1}’, // the return fields selector

Procedure (Sender: TObject; JSONRowData: TALJSONNode)
begin
writeln(‘New item added in cappedCollectionExemple: ‘ + JSONRowData.childnodes[‘fieldA’].text);
end,

procedure (Sender: TObject; Error: Exception)
begin
writeln(Error.message);
end);
….
aMongoDBTailMonitoringThread.free;
WebSocket client
WebSocket Client for Delphi implemented on the top of WinHTTP. The WebSocket is a communication protocol, that makes it possible to open a two-way interactive communication session between the user’s browser and a server. With this, you can send messages to a server and receive event-driven responses without having to poll the server for a reply.

Fast TStringList
TALStringList Work the same as Delphi TStringList except that it’s allow to search a name=value using a quicksort algorithm when the list is sorted. Also TALStringList use a locale independent algorithm (based on the 8-bit ordinal value of each character) instead of the AnsiCompareText and AnsiCompareStr used by the Delphi TStringList. at the end the sort in TALStringList is up to 10x more faster than in Delphi TStringList. Also TALStringList is not an Unicode TStringList but an 100% Ansi StringList

TALNVStringList (NV for NameValue) is same as TALStringList (use also a quicksort algorithm) except that here optimization is oriented for name/value list instead of string list.

TALHashedStringList TALHashedStringList is same as TALStringList except that it’s use an internal hash table instead of a quicksort algorithm. By using TALHashedStringList instead of TALStringList, you can improve performance when the list contains a large number of strings (else if you list don’t contain a lot of strings the performance is lower than TALStringList because of the cost to calculate the hash)

PHP runner
ALPHPRunnerEngine is a simple but useful component for easily use php (any version) as a scripting language in Delphi applications. ALPhpRunnerEngine allows to execute the PHP scripts within the Delphi program without a WebServer. ALPHPRunnerEngine use the CGI/FastCGI interface (php-cgi.exe) of PHP to communicate with PHP engine.

Memcached Client
Delphi Client for memcached database.

What is Memcached? Free & open source, high-performance, distributed memory object caching system, generic in nature, but intended for use in speeding up dynamic web applications by alleviating database load.

Memcached is an in-memory key-value store for small chunks of arbitrary data (strings, objects) from results of database calls, API calls, or page rendering.

Memcached is simple yet powerful. Its simple design promotes quick deployment, ease of development, and solves many problems facing large data caches.

GSM component
The TAlGSMComm component implements SMS text messaging through the text-mode interface defined in the GSM Technical Specification 07.05, version 5.1.0, dated December 1996. There are several variations of this spec, used throughout Nokia, Siemens, Ericsson, etc models. We have tested the Nokia 6230 in-house, but the Nokia 7190, 8890, 6210 and 9110 models should work as well. Phones from other manufacturers will also work, as long as they implement the text-mode interface. About 1/4 of the current phones are capable of being connected to a PC (through IR or serial cable), about 1/3 of those are text-mode only, 1/3 are PDU mode only, and the other 1/3 support both text and PDU mode. Some phones (such as the Nokia 5190) support SMS, but they use a proprietary protocol, which TALGSMComm does not support.

To test your phone, connect the phone to your PC through the serial cable or IR device (consult your phone’s documentation for details on how to connect). Enter “AT” into a terminal window to verify the connection is established (you should receive “OK” from the phone), then enter “AT+CMGF=?”. The response should contain a “1”, indicating that it supports text-mode. If both of these tests pass, then your phone meets the basic requirements.

WIN64
Unfortunately, in win64 we lost all the FastCode heritage. (that was mostly based on ASM). That mean that most of the functions will be around 2x to 10x more slower. you can try to launch /demo/ALStringBenchMark/ in win64 and Win32 to see the difference in speed.

Delphi 5 TDateTimePicker Format

During add Delphi 5 compatibility to the Purchase Order calculation sample of HotXLS Delphi Excel Spreadsheet component, an error occurred while compiling under Delphi 5.

The line which set the date format of the TDateTimePicker control does not compile:

TDateTimePicker control of Delphi is a wrapper around a Microsoft control. It allows you to show the date in one of two formats (long and short), but in Delphi 5 and lower, it did not allow you to change the DateTime format. That’s because it uses the Windows date and time settings, not Delphi’s internal format variables like “ShortDateFormat”.

In Delphi 6 and later, you can use the Format property to change the display of date or time.

In Delphi 5 and earlier, you should use the DateTime_SetFormat function to set the format, this function in the “CommCtrl” unit, you should add CommCtrl to the “USES” column, otherwise, the DateTime_SetFormat won’t be recognized.

The fix for our sample project looks like this:

ftol and the 64bit Delphi inline asm changes

Above is a Delphi inline asm version of the ftol (Floating Point to Integer Conversion) function used by our HotPDF Delphi PDF component.

When compiling above Delphi codes in the 64-bit target platform, Delphi will raise below error:
[dcc64 Error] E1025 Unsupported language feature: ‘ASM’

The reason is: The 64-bit Delphi compiler DCC64 does not support mixed Pascal/assembly code.
DCC64.EXE supports 64-bit assembly code, but the routines must be written completely in assembler.

In addition, the 64-bit asm codes have many different than the 32-bit ones, you can not copy the 32-bit asm codes to the 64-bit assembler routines directly, you must re-write them from scratch, I found below codes from the internet:

But maybe we do not really need assembly this routine,

The trunc function of Delphi just returns the integer part of a floating point number, that’s the conversion from floating point to integer. The speed of this version should be not bad.

Delphi Incompatible type tagLOGBRUSH tagLOGBRUSH32

When using Delphi XE2 or above editions to compile coeds likes below:

The compiler says: E2010 Incompatible types: ‘tagLOGBRUSH’ and ‘tagLOGBRUSH32’.

The solution to fix this compiling error is:

C++Builder dynamic create & delete HotPDF component instance

This example shows you how to programmatically New and Free a HotPDF object instance with C++Builder.

You need to set the include & library path of the project to the directory where HotPDF library files exist.
