Open Symbolic Notation, abbreviated OSN, is an easy and flexible data-interchange text format intended for the lightweight representation of generic abstract syntax trees in the domain of formal languages. Additional information is available at OSN web site. -

Helena

+

+

Helena

+

Helena is a processor for the systems of the Î»Î´ family, implemented in Caml as a part of the HELM software, meant for testing both their stable and unstable features. -

+

+

The processor source code is available in the directory /trunk/helm/software/helena/ of the HELM Svn repository. The Svn revisions containing the stable versions of Helena are indicated next. -
