Some thoughts about "modern" pascal, generics, code and data structures

In a comment of a Google+ announcement about new C# features, Stephan did react about my naive enthusiasm about SmartPascal.

Apart from the fact that he did miss the numerous ways of creating Windows executable in this dialect (I quoted at least 5 diverse ways), he was chocked by the fact that the SmartPascal syntax, in its actual idiom, does not support generics.

But are generics mandatory?
I'm not speaking about any drug identified by its chemical name rather than its brand name (Wikipedia).
I would neither comment on the current Delphi implementation of generics (which may appear not so polished, nor very widely used, even in the Delphi RTL/FMX, but for TList<T> TDictionary<>).
Just share some thoughts about what is, to my opinion - which may be wrong and biased! - the most important part of today's programming.

Cross-Platform mORMot Clients - Smart Mobile Studio

Current version of the main framework units target only Win32 and Win64 systems.

It allows to make easy self-hosting of mORMot servers for local business applications in any corporation, or pay cheap hosting in the Cloud, since mORMot CPU and RAM expectations are much lower than a regular IIS-WCF-MSSQL-.Net stack.
But in a Service-Oriented Architecture (SOA), you would probably need to create clients for platforms outside the Windows world, especially mobile devices.

A set of cross-platform client units is therefore available in the CrossPlatform sub-folder of the source code repository. It allows writing any client in modern object pascal language, for:

  • Any version of Delphi, on any platform (Mac OSX, or any mobile supported devices);
  • FreePascal Compiler 2.7.1;
  • Smart Mobile Studio 2.1, to create AJAX or mobile applications (via PhoneGap, if needed).

This series of articles will introduce you to mORMot's Cross-Platform abilities:

Any feedback is welcome in our forum, as usual!

Benchmarking Mustache libraries: native SynMustache vs mustache.js/SpiderMonkey

I just wrote a small sample program, for benchmarking Mustache libraries: native SynMustache vs mustache.js running on SpiderMonkey 24...

And the winner is ...SynMustache, which is 10 times faster, uses almost no memory during process, and handles inlined {{>partials}} natively (whereas we have to handle them manually with mustache.js)!

Who says that Garbage Collection and immutable strings in modern JITted runtimes are faster than "native" Delphi applications?
Are you still preferring the "NextGen" roadmap?

Mustache Logic-less templates for Delphi - part 3

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.

JavaScript support in mORMot via SpiderMonkey

As we already stated, we finished the first step of integration of the SpiderMonkey engine to our mORMot framework.
Version 1.8.5 of the library is already integrated, and latest official revision will be soon merged, thanks to mpv's great contribution.
It can be seen as stable, since it is already used on production site to serve more than 1,000,000 requests per day.

You can now easily uses JavaScript on both client and server side.
On server side, mORMot's implementation offers an unique concept, i.e. true multi-threading, which is IMHO a huge enhancement when compared to the regular node.js mono-threaded implementation, and its callback hell.
In fact, node.js official marketing states its non-blocking scheme is a plus. It allows to define a HTTP server in a few lines, but huge server applications need JavaScript experts not to sink into a state a disgrace.
