[isabelle] command "types" on Isabelle 2012
I am starting with Isabelle/Hol and I have some doubts (millions in
fact... :-) ). I am using an existing theory that runs well under
Isabelle 2009-2, but it does not on Isabelle 2012. I am trying to make
it work on this version, but I am finding some problems and although I
have been looking for there is not too much documentation.
In particular I am having parsing errors on some statements using
In the 2009 version the code is like this:
types type8 ="type_length8 Word"
translations (type) "type8" <= (type) "type_length8 word"
It seems that this is not available anymore. I have replaced "types" by
"type_synonym", are types and type_synonym equivalent?
Once modified this, this theory imports "Enum" theory. Again, this is
not a problem in Isabelle 2009-2, but Isabelle 2012 loads its own Enum
theory. Is it possible not to load "Enum" in Isabelle 2012 so I can use
the Non-Isabelle theory?? or should I have to rename the theory, and
probably also the class enum?
Thank you for your help,
