I just finished my workshop at EKON 23.
Like every year, it was a great event to attempt to, and I enjoyed presenting 2
sessions and 1 workshop.
Sessions were about "Kingdom Driven Design" (KDD), which is the
name I used to define a cut-down version of "Domain Driven Design" (DDD).
Less paranoid, a bit less isolation, but perhaps more common sense for the less
sensitive projects.
Some presentations and code are now available!

2015-11-21. Pascal Programming
There is a very trendy move, since a few years, to value so called "meta-programming".
In short, it is about the ability to treat programs as their data.
It is a very powerful paradigm in functional languages, and it was also
introduced to OOP languages, even in SmallTalk a long time
before this concept was trendy in Ruby, C# or Java.
In OOP compiled languages, reflection is used to achieve a similar behavior
at run-time, mainly via RTTI (Run-Time Type
Information).
Delphi supports
RTTI since its version 1, as it was heavily used e.g. for all UI
streaming.
In our framework, we rely on RTTI for its main features:
ORM, SOA
and
MVC - and even in some other parts, like
Desktop UI generation.
But RTTI could easily be abused.
Here are some thoughts, started as a comment in a
good old Mason's blog article about how RTTI performance may be a
bottleneck.
My comment was to get rid of RTTI, and follow a SOLID
implementation with explicit OOP code, like use of
interface.

2014-10-24. Open Source › mORMot Framework
We almost finished implementing a long-standing feature request,
introducing MVC / MVVM for Web Applications (like RubyOnRails) in mORMot.
This is a huge step forward, opening new perspectives not only to our
framework, but for the Delphi community.
In respect to the existing
MVC frameworks for Delphi, our solution is closer to Delphi On Rails (by the
convention-over-configuration
pattern) than the Delphi MVC
Framework or XMM.
The mORMot point of view is unique, and quite powerful,
since it is integrated with other parts of our framework, as its ORM/ODM or interface-based services.
Of course, this is a work in progress, so you are welcome to put your feedback,
patches or new features!
We will now explain how to build a MVC/MVVM web application using
mORMot, starting from the "30
- MVC Server" sample.
First of all,
check the source in our GitHub repository: two .pas files, and
a set of minimalist Mustache
views.
This little web application publishes a simple BLOG, not fully finished yet
(this is a Sample, remember!).
But you can still execute it in your desktop browser, or any mobile device
(thanks to a simple Bootstrap-based responsive design), and see the
articles list, view one article and its comments, view the author information,
log in and out.
This sample is implemented as such:
| MVVM | Source | mORMot |
| Model | MVCModel.pas |
TSQLRestServerDB ORM over a SQlite3 database |
| View | *.html |
Mustache template engine in the Views sub-folder |
| ViewModel | MVCViewModel.pas |
Defined as one IBlogApplication interface |
For the sake of the simplicity, the sample will create some fake data in its own local SQlite3 database, the first time it is executed.

Mustache is
a well-known logic-less template engine.
There is plenty of Open Source implementations around (including in JavaScript,
which can be very convenient for AJAX applications on client side, for
instance).
For mORMot, we created the first pure Delphi implementation of it,
with a perfect integration with other bricks of the framework.
In last part of this series of blog articles, we will introduce the
Mustache library included within mORMot source code
tree.
You can download this documentation
as one single pdf file.
