We are happy to announce Dezyne 2.20 which introduces global function and foreign function. This release represents 111 commits over three years.
See the NEWS below for a brief summary.
Here is the Dezyne home page:
https://dezyne.org
What's next?
In the next releases we would like to see:
- Improved performance of the Well-formedness check.
- Performance improved parse infrastructure including normalization.
- New sequential simulator infrastructure with improved support for
systems, constraining interfaces, shared state, and debugging
communcations labeled with external and defer.
See the ROADMAP in GIT for details.
Enjoy!
The Dezyne developers.
ABOUT
Dezyne is a programming language and a set of tools to spoecify,
validate, verify, simulate, document, and implement concurrent control
software for embedded and cyber-physical systems.
The Dezyne language has formal semantics expressed in mCRL2
(https://mcrl2.org) developed at the department of Mathematics and
Computer Science of the Eindhoven University of Technology
(https://tue.nl). Dezyne requires that every model is finite,
deterministic and free of deadlocks, livelocks, and contract violations.
This is achieved by means of the language itself as well as by builtin
verification through model checking. This allows the construction of
complex systems by assembling independently verified components.

Use a .sig file to verify that the corresponding file (without the
.sig suffix) is intact. First, be sure to download both the .sig file
and the corresponding tarball. Then, run a command like this:
gpg --verify .sig
The signature should match the fingerprint of the following key:
pub rsa4096 2018-04-08 [SC]
1A85 8392 E331 EAFD B8C2 7FFB F3C1 A0D9 C1D6 5273
uid [ full ] Jan (janneke) Nieuwenhuizen <[email protected]>
If that command fails because you don't have the required public key,
or that public key has expired, try the following commands to retrieve
or refresh it, and then rerun the 'gpg --verify' command.
gpg --recv-keys 1A858392E331EAFDB8C27FFBF3C1A0D9C1D65273
As a last resort to find the key, you can try the official GNU
keyring:
wget -q https://ftp.gnu.org/gnu/gnu-keyring.gpg
gpg --keyring gnu-keyring.gpg --verify .sig
This release is based on the dezyne git repository, available as
git clone git://git.savannah.nongnu.org/dezyne.git
with commit tagged as v2.20.0.
For a summary of changes and contributors, see:

or run this command from a git-cloned dezyne directory:
git shortlog v2.19.3..v2.20.0
Alternatively, Dezyne can be installed using GNU Guix:
guix pull
guix install dezyne
