Output.timing;

improved output;

moved print_mode to General/output.ML; load General/pretty.ML early;

added Pure/General/output.ML;

avoid 'handle _' -- would cover Interrupt as well!!!

Sign.infer_types: Sign.pp;

Library.read_int;

Output.output;

'classrel': support multiple arguments;

* ML: all output via channels of writeln etc. passed through Output.output;

output channels;

added asm_lr_simplify/asm_lr_rewrite and adapted asm_full_simplify/asm_full_rewrite to match to corresponding simp_tacs

new skolemize_tac and skolemize method

new theorem Collect_imp_eq

abstraction over functions is no default any more.

adjusted for different signature of Type.typ_instance

mainly new/different datatype examples

documentation updated

major code change: refute can now handle any Isabelle term, adds certain axioms automatically, and can handle inductive datatypes (but not yet recursion over them)

new default parameters for refute

solver "auto" now issues a warning when it uses solver "enumerate"

Corrected printer bug for bounded quantifiers Q x<=y. P

more group isomorphisms

added drop_take:thm

- deleted unneeded function eta_long (now in Pure/pattern.ML - added HOL.min / HOL.max to allowed consts again - added final simplification step with presburger_ss to preprocessor again

Adapted to new syntax for case expressions.

Added more flexible parse / print translations for case expressions.

Modified functions pt_to_ast and ast_to_term to improve handling of errors in parse (ast) translations caused by ambiguous input.

- exported result datatype - added functions get_result and get_exn

updated;

Pure: clear separation of logical types and nonterminals;

adapted tsig/sg interface;

added dest, minimals, maximals, is_edge, add_edge/merge_trans_acyclic;

added fold, product; removed transitive_closure;

adapted names of some sort ops;

major cleanup of tsig datastructures and extend/merge operations; fixes old bugs in classes/arities code; proper treatment of nonterminals and syntax-only types;

Type.strip_sorts;

incorporate type inference interface from type.ML;

adapted tsig interface;

moved some sort ops to sorts.ML; added string_of_vname (from Syntax module);

test_classrel/arity improve error reporting; tuned;

xxx_typ_raw replace xxx_typ_no_norm forms; prevent duplicate consts declarations in merge; misc cleanup;

string_of_vname moved to term.ML;

incorporate sort ops from term.ML; use Graph.T; misc cleanup;

type.ML now before Syntax module;

xxx_typ_raw replace xxx_typ_no_norm forms;

'classrel' now allows multiple arguments;

Sign.certify_tyname;
