The Diet template language is aimed at providing a way to
define procedurally generated HTML/XML pages (or other output
formats), with minimal visual noise. Syntax and feature set are
heavily inspired by Jade <http://jade-lang.org/>, but instead
of JavaScript, all expressions and statements are D statements,
and everything that can be done at compile-time is done at
compile-time.
Vibe.d still contains the original implementation, which was
written around the limitations of DMD's CTFE engine back years
ago, and is basically a monolithic parser+generator with little
flexibility and a number of convenience features missing,
because of their implementation complexity. The new
implementation has been rewritten cleanly, with separate
parser, modifier and generator modules, working on a common DOM
tree intermediate representation.
The major new features/improvements are:
- No external dependencies other than Phobos
- Supports inline and nested tags syntax
- Supports string interpolations within filter nodes (falls
back to
runtime filters)
- Supports AngularJS special attribute names
- Extensible/configurable with traits structures
- Uses less memory during compilation (this one was a real
surprise)
- (Unit) tested from the start
- Supports arbitrary uses other than generating HTML, for
example we
use it similar to QML/XAML for our internal UI framework
The API documentation can be shown ba running DUB:
dub fetch diet-ng --version=1.0.0-alpha.2
dub run diet-ng -b ddox
You can try the library directly, or together with the latest
alpha release of vibe.d (0.7.30-alpha.3). Simply add a
dependency to "diet-ng", version "~>1.0.0-alpha.2". Vibe.d will
automatically re-route render!(...) calls to diet-ng.
A small example with just the most essential features is shown
in the README:
https://code.dlang.org/packages/diet-ng
More complex real-world examples:

Any comments/requests regarding the feature set or API are
highly welcome!
Great stuff! Very much appreciated. Btw, the link to
jade-lang.org (don't click!) leads to a dodgy business homepage
atm. The right address is
http://jade-lang.com/
