This README belongs to a "The heterogeneous tool set" (Hets) source

release created by "make release" from the original svn repository.

(for svn see http://subversion.tigris.org/)

The original svn sources can be obtained by:

svn co https://svn-agbkb.informatik.uni-bremen.de/Hets/trunk Hets

Information not contained here can be found in the Hets user guide

(doc/UserGuide.pdf) or on the Hets web page www.dfki.de/sks/hets.

The subject of this source release is to create a binary "hets" that

is able to analyse heterogeneous and in particular CASL

specifications.

The sources need to be compiled using ghc Glasgow Haskell Compiler

(www.haskell.org/ghc) version 6.8.3! Haskell as a logic is also

a part of Hets via "Programatica"

(www.cse.ogi.edu/PacSoft/projects/programatica).

Beside output written to the console (stdout) or to files, hets can

display graphs using "uDraw(Graph)", formerly "daVinci"

(www.informatik.uni-bremen.de/uDrawGraph)

Additionally, in particular for the binding to uDrawGraph,

the sources of the uniform workbench are required:

For hets (and uni) to find "uDrawGraph", the environment variables UDG_HOME and

UNIDAVINCI must be set to the installation directory of uDraw(Graph) and to

the actual executable, respectively.

export UNIDAVINCI=$UDG_HOME/bin/uDrawGraph

A typical call of hets is then: hets -g Basic/Numbers.casl

Example specifications can be found under:

If you need to build the hets binary follow the instructions in

INSTALL, alternatively try to get a binary or a complete installer from:
