Migration to github for all my open source projects… done!

Since when Google announced that Google Code will be closed I did start to plan the migration of all my open source projects. Now, the migration is terminated.

In the next days, I’ll add all the contributors too, so that the development can go forward as usual.

These are the projects

  • DelphiMVCFramework
    • if you are reading my Delphi Cookbook, please use this new repository instead of the old SVN one, reported in the book.
  • DORM, the Delphi ORM
  • DelphiRedisClient
  • DelphiDIContainer
  • DelphiSTOMPClient

All the repositories are available on my personal github page https://github.com/danieleteti and, as usual all contributions are welcome.

Enjoy.

 

My “Delphi Cookbook” has been published

Almost an year ago I started to write a book about Delphi for Packt Publishing. Today that book has been published.

Delphi Cookbook Cover
Delphi Cookbook Cover

This book is a cookbook! That’s it, in 328 pages you will find useful (I hope) “recipes” for your day-by-day Delphi job.

Topics of the book

  • Create visually stunning applications using FireMonkey
  • Effectively use LiveBindings with the right OOP approach
  • Create server-side programs to serve RESTful web services and provide data to your mobile apps
  • Develop mobile apps for Android and iOS using well-defined GUI design patterns for a great user experience
  • Build efficient mobile apps that read data from a remote server
  • Call the platform-native API on Android and iOS even for an unpublished API
  • Use extended RTTI to better manage the software customization for your customer
  • Leverage the most popular design patterns for a better design without wasting too much time debugging

It is not an introductory book, you will not find any “Introduction to the Object Pascal language”, however the majority of the chapters are not too complex and can be grasped also by the new Delphi programmers.

The book is available for sale on the editor website and on Amazon.

DelphiMVCFramework is now Open Source!

delphimvcframework

Yes, just after 1 year of development, and a couple of big projects developed with it, the DelphiMVCFramework has been published as OpenSource.

The project is on google code svn https://code.google.com/p/delphimvcframework/

I’ll talk about it at ITDevCon2013 (http://www.itdevcon.it)

In the trunk there are many samples and I’m planning to put many others.

Main DMVCFramework features

  • RESTful (RMM Level 3) compliant
  • Server side generated pages using eLua (Embedded Lua)
  • Messaging extension using STOMP (tested with Apache Apollo and Apache ActiveMQ)
  • Can be used in load balanced environment using memcached (memcached.org)
  • Fancy URL with parameter mappings
  • Integrated RESTClient
  • Works with XE4 and XE5 (tested, but should works also on XE3 and XE2)
  • Experimental support for IOCP
  • Simple, but very very simple, to use…

It contains also a lot of indipendent code that can be used in other kind of projects.

These are the most notable:

  • Mapper (convert JSON <=> Object, ObjectList <=> JSONArray, ObjectLists <=> DataSets)
  • LuaBinding (integrate Lua script into Delphi native code)
  • LuaTextFilter (convert eLua into plain Lua executable script just like JSP)
Currently DMVCFramework use Embarcadero WebBroker framework, but is not tied to it. I’m working on a version that use IOCP (that is 10 times faster than plain WebBroker) and other web libraries for Delphi.
Code is enough stable and is already used in big production system.
WARNING!
There are a couple of bugs that affect WebBroker and so, DMVCFramework.
In our system, I’ve applied some patches to solve these problems. If you need those patches, ask me (I cannot publish the full code because it is Embarcadero licensed code).
The bugs are:
And another bug that affect also DataSnap and TIdHTTPWebBrokerBridge based projects.
Code is tested on XE4 and XE5 but should works also on XE3 and XE2.

Sending Android Intents from Delphi (Part 1)

As you probably know, I work for the italian embarcadero representative (www.bittime.it), so last week, I’ve been in Milan (Italy) with the Delphi Product Manager Marco Cantù, to show the new Delphi XE5 for Android (and iOS…).

Users (old and new) were enthusiastics. The Delphi-WAY combined with the Android openness and flexibility, is really a good way to develop mobile apps for the business customers.

So, after the initial demos some users were interested in sending Android Intents from their Delphi app.

I’ve builded some demos about Intents, so I showed those demos to them (in the next weeks there will be many Delphi for Android training in Italy, so I’ve build those demo in advance)

In Delphi XE5 you can call java classes from the Google SDK. So I started investigating hot to do this.

There are a lot of possibilities, and I’m still doing research, but this is a simple Intent send demos.

The Intents demo app
The Intents demo app

 

This is the code under the first button.

procedure THeaderFooterForm.Button1Click(Sender: TObject);
var
  Intent: JIntent;
begin
  // JAVA SDK ANDROID HELP SAYS...
  // String url = "http://www.example.com";
  // Intent i = new Intent(Intent.ACTION_VIEW);
  // i.setData(Uri.parse(url));
  // startActivity(i);

  Intent := TJIntent.Create;
  Intent.setAction(TJIntent.JavaClass.ACTION_VIEW);
  Intent.setData(TJnet_Uri.JavaClass.parse
    (StringToJString('http://www.danieleteti.it')));
  MainActivity.startActivity(Intent);
end;

Simple, isn’t it?

With this piece of code, you cann open your device browser to a web site (my blog in the snippet).

Click on the first button and you will be redirected to this blog.

Open browser with intent
Open browser with intent

 

Intents are REALLY powerfull

With the next snippet, you can send piece of data (e.g. text) to other apps. You dont have to know the apps in advance, Android will do the match with the Implicit Intent. (It is similat to the TShowShareSheet action).

procedure THeaderFooterForm.Button2Click(Sender: TObject);
var
  Intent: JIntent;
begin
  // Intent intent = new Intent(Intent.ACTION_SEND);
  // intent.setType("text/plain");
  // intent.putExtra(android.content.Intent.EXTRA_TEXT, "Android Rocks!!!");
  // startActivity(intent);

  Intent := TJIntent.Create;
  Intent.setType(StringToJString('text/plain'));
  Intent.setAction(TJIntent.JavaClass.ACTION_SEND);
  Intent.putExtra(TJIntent.JavaClass.EXTRA_TEXT,
    StringToJString('Delphi Rocks!!!'));
  MainActivity.startActivity(Intent);
end;
Chose wich apps shoud be launched to handle the intent (and the text)
Chose wich apps shoud be launched to handle the intent (and the text)

 

Now, if you choose Twitter, you will get this screen.

Intent handle by twitter app
Intent handle by twitter app

 

I’ve demos about placing a call, sending an SMS, show a PDF file, accessing different kind of storage etc.
In the next part of this mini series I’ll show some other snippets.

There is still many areas to explore…

  • Services
  • BroadcastReceiver
  • Widget
  • Bluetooth
  • I/O
  • …?

I’ll keep you informed…
