replaced ancient sys_error by raise Fail, assuming that the latter is not handled specifically by the environment;

try_param_tac: plain user error appears more appropriate;

replaced ancient sys_error by raise Fail, assuming that the latter is not handled specifically by the environment;

eliminated dead code;

more conventional exceptions for abstract syntax operations -- eliminated ancient SYS_ERROR; proper signature constraint;

removed assumption

more on naming tactics;

tuned proof

tuned proof

tuned lemma proposition of properties_for_sort_key

lemmas sorted_map_same, sorted_same

lemmas multiset_of_filter, sort_key_by_quicksort

more on "Time" in Isabelle/ML;

simplified some time constants;

added convenience operation seconds: real -> time;

avoid catch-all exception handling;

eliminated fragile catch-all pattern, based on educated guess about the intended exception;

Attribute map_function -> coercion_map; tuned;

syntax category "real" subsumes plain "int";

merged

Plus -> Sum_Type.Plus

Minor reformat.

support for real valued preferences;

support for real valued configuration options;

support for floating-point tokens in outer syntax (coinciding with inner syntax version);

merged

added rule let_mono

CONTRIBUTORS;

more sharing of operations, without aliases;

simplified data lookup;

export declarations by default, to allow other ML packages by-pass concrete syntax; proper Args parsing for attribute syntax (required for proper treatment of morphisms when declarations are moved between contexts); tuned;

proper signature constraint for ML structure; explicit theory setup, which is customary outside Pure; formal @{binding} instead of Binding.name;

proper header; tuned whitespace;

Coercive subtyping via subtype constraints, by Dmitriy Traytel (21-Oct-2010).

updated SMT certificates

eta-expand built-in constants; also rewrite partially applied natural number terms

optionally drop assumptions which cannot be preprocessed

added crafted list of SMT built-in constants

clarified error message

tuned

introduced SMT.distinct as a representation of the solvers' built-in predicate; check that SMT.distinct is always applied to an explicit list

merged

added listrel1

hide Sum_Type.Plus

merged

added user aliasses (still unclear how to specify names with whitespace contained)

merged

tuned structure of theory

remove term_of equations for Heap type explicitly

no need for setting up the kodkodi environment since Kodkodi 1.2.9

fixed order of quantifier instantiation in new Skolemizer

restructure Skolemization code slightly

ensure that MESON correctly preserves the name of variables (needed by the new Skolemizer)

more work on new Skolemizer without Hilbert_Choice

fix cluster numbering in the absense of Hilbert_Choice (reverts acde1b606b0e, effectively reintroducing most of 0bfaaa81fc62)

prevent type errors because of inconsistent skolem Var types by giving fresh indices to Skolems

make handling of parameters more robust, by querying the goal
