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.

Delphi XE4 NextGen compiler: using byte instead of ansichar?

When I first read the technical white paper covering all of the language changes in XE4 for mobile development (tied to the new ARM LLVM-based Delphi compiler), I have to confess I was pretty much confused.

Two great mORMot users just asked for XE4/iOS support of mORMot.

Win32/Win64 support for XE4 will be done as soon as we got a copy of it.
I suspect the code already works, since it was working as expected with XE3, and we rely on our own set of low-level functions for most internal work.

But iOS-targetting is more complex, due to the NextGen compiler, mainly.

Adding JavaScript server-side support to mORMot

A long-time mORMot user and contributor just made a proposal on our forums.
He did use mORMot classes to integrate a SpiderMonkey JavaScript engine to our very fast and scaling HTTP server, including our optimized JSON serialization layer.

Today, he sent to me some of his source code, which sounds ready to be included in the main trunk!

This is a great contribution, and Pavel's goal is nothing less than offering
Delphi based, FAST multithreaded server with ORM and node.js modules compatible.

Go language and Delphi

Do you know the Go language?

It is a strong-typed, compiled, cross-platform, and concurrent.
It features some nice high-level structures, like maps and strings, and still have very low-level access to the generated code: pointers are there, in a safe strong-typed implementation just like in pascal, and there is even a "goto", which sounds like an heresy to dogmatic coders, but does make sense to me, at least when you want to optimize code speed, in some rare cases.

It is created/pushed by Google, used internally by the company in their computer farms, and was designed by one of the original C creators.

How function results are allocated

One potential issue with Delphi coding, is about how the result of a functions are implemented.

If you forget to set a result value to a function, you'll get a compiler warning.
Never underestimate such warning: IMHO this is not a warning, but an error.

And you should better be aware of the handling of reference-counted types (e.g. string) in a function results: those are passed the stack as var parameters, so the result of a function may be set even if an exception is raised during function execution!
