# New "Imperative" Syndicate Implementation

This experimental reimplementation of Syndicate takes the
language-level constructs of facets, endpoints, and fields to heart,
and integrates knowledge of facets and endpoints into the dataspace
implementation itself.

It gains a *significant* performance advantage by doing so.

Programs seem to be about *20x faster*. Some are only 10x faster, some
are 30x faster.

The prototype that embodies the new idea is in
[prototype.rkt](prototype.rkt).

All the drivers end up looking much nicer with this new
implementation. The previously-separate GL-2D support is now
integrated as just another driver (though the timing characteristics
of the old implementation are not precisely preserved). The
[ground.rkt](ground.rkt) implementation is much cleaner.

Install the package by getting a Git checkout and running

```shell
raco pkg install --link -n imperative-syndicate `pwd`
```

The implementation test suite lives in [test/](test/). Run it with:

```shell
raco setup imperative-syndicate; raco test -p imperative-syndicate
```

Try out the "many Racket logos" animation example/demo:

```shell
racket examples/gl-2d-many.rkt
```

Hopefully you'll get a smooth 60fps, though I admit I'm running it on
a fairly fast machine so you might need to drop the sprite-count in
the code a bit to sustain 60fps.
