Subject: [Hets-devel] New meaning of HETS_ISABELLE
Message-ID: <41E2C575.3010905@informatik.uni-bremen.de>

Dear Hetters,

for a tool demo in Bangalore, Lutz and I need to customize Isabelle/ProofGeneral
with large fonts.

We therefore found it more convenient to let HETS_ISABELLE point to the Isabelle
binary, instead of the Isabelle main folder: one can then just set HETS_ISABELLE
to different shell scripts invoking different font sizes.

After the next update, you need to update your HETS_ISABELLE setting accordingly.

Greetings,
Till

Subject: [Hets-devel] hets with programatica
Message-ID: <41E2B7D2.4070306@tzi.de>

Hi,

in order to include a Haskell logic and a translation from HasCASL to 
Haskell into hets the programatica cvs repository must be checked out in 
the same directory where HetCATS and uni reside.

(The Makefile checks for $(wildcard ../programatica/tools))

Programatica comes from
http://www.cse.ogi.edu/~hallgren/Programatica/

and can be checked out via:

    1. cvs -d :pserver:anoncvs@cvs.haskell.org:/cvs login
    2. Enter the password: cvs.
    3. cvs -d :pserver:anoncvs@cvs.haskell.org:/cvs checkout programatica


(the name "glass.cse.ogi.edu" instead of "cvs.haskell.org" also works)

All haskell code is analyzed in a single Prelude module, therefore 
qualified names are not supported. Subject to change may be the 
inclusion/treatment of prelude functions. Currently not much more than 
Haskell tuples are known for a translation from HasCASL.

Via HasCASL also CASL can be translated to Haskell.

I'ld like to translate some free HasCASL types to Haskell data types 
with "deriving (Show, Eq, Ord)", but theses classes depend on more 
prelude function than currently included. The HasCASL2HasCASL morphism 
is intended to translate certain formulas to executable program 
equations. In some cases overlapping patterns are generated, in other 
cases "Eq" instances are missing.

Cheers Christian
