After much debugging and tweaking and testing and polishing, we're
declaring Slate as ready for release as 0.3, our first public
fully-bootstrapped system. This is a big step for us, and marks a
critical point in the lifespan of the project. Here is a summary of the
Slate is now virtual-machine-based using a self-generated set of sources
which are idiomatic and efficient. The VM is generated through a build
process and translation layer which are designed for easy extension,
composition, and integration. The VM loads images which can be built
declaratively through a from-scratch build process we have developed and
can be re-used and modified as needed. Images may also be saved while
running, and reloaded to continue from that run-time point. Much of the
work involved in 0.3 has gone towards ensuring that this new environment
is effectively bug-free and robust, and has succeeded for all the ways
the libraries use it.
Relatively simple optimizations have been added to improve performance,
and have had the effect of nearly-entirely removing the overhead of the
powerful but complicated dispatch mechanism, and making Slate comparable
with other similar languages for basic work.
Nearly every library in the system has been given a full test treatment,
and debugged and polished thoroughly. The fixes and enhancements cover
everything from the C-code generator to streaming and external resources.
Some features have been delayed in their introduction to the new
environment, particularly subjective dispatch, graphics backends, and
socket support, but these will be available soon in subsequent sub-point
releases along with other important features.
Slate 0.3 is released at http://slate.tunes.org/downloads/slate-0.3.tgz
The distribution contains the full set of our repository's source,
initial VM C sources and images, and copies of the programmer's manual
in HTML, PostScript, and PDF formats. The included README file provides
details on how to use it.
