fixed spelling;

removed unused "boundary" of Table/Graph.get_first;

proper treatment of paths passed to the shell -- to allow spaces in file names as usual;

renamed system/system_out to bash/bash_output -- to emphasized that this is really GNU bash, not some undefined POSIX sh;

misc tuning;

merged

adjusted to changeset 118b41bba42b5

tuned font handling; explicit workaround for Apple's font manager in Java 1.6, which fails to create "IsabelleTextBold" as family member of "IsabelleText";

updated versions of requirements;

filter out identical completions only after symbols.decode -- recover completion of literal symbols (e.g. \<AA>);

eliminated self intersection and non-integer coordinates;

try "GTK+" as well -- note that "Nimbus" is unavailable in versions of OpenJDK;

updated generated files;

merged

Changed 'bounded unique existential quantifiers' from a constant to syntax translation.

four changes to Nitpick: 1. avoid writing absolute paths in Kodkodi files for input/output files of external SAT solvers (e.g. MiniSat), to dodge Cygwin problems 2. do eta-contraction in the monotonicity check 3. improved quantifier massaging algorithms using ideas from Paradox 4. repaired "check_potential" and "check_genuine"

capture error messages (of SMT solvers)

Removed explicit type annotations

adjusted to changes in List_Set.thy

more correspondence lemmas between related operations

canonical insert operation; generalized lemma foldl_apply_inv to foldl_apply

dropped some redundancies

generalized lemma foldl_apply_inv to foldl_apply

more correspondence lemmas between related operations; tuned some proofs

new theory Algebras.thy for generic algebraic structures

tuned structure; moved non-related quickcheck.setup to Code_Generator.thy

Changed author; removed debugging code.

merged

adding Mutabelle to repository

Replaced vec1 and dest_vec1 by abbreviation.

merged

HOLogic.strip_psplits: types are ordered after syntactic appearance, not after corresponding de-Bruin index (closer correspondence to similar strip operations)

merged

support skolem constant for extensional arrays in Z3 proofs

drop underscores at end of names coming from Boogie

merged

correctly hiding facts of Lazy_Sequence

corrected and simplified Spec_Rules registration in the Recdef package

merged

adopting predicate compiler to new Spec_Rules and eliminating the use of Nitpick_Simps

adopting Sequences

added registration of equational theorems from prim_rec and rec_def to Spec_Rules

simplified proofs

NEWS

more accurate dependencies

code literals: distinguish numeral classes by different entries

cleanup of Multiset.thy: less duplication, tuned and simplified a couple of proofs, less historical organization of sections, conversion from associations lists to multisets, rudimentary code generation

merged

dropped some old primrecs and some constdefs

explicit CONST in translations

modernized syntax

fix issues with previous Nitpick change

merged

some work on Nitpick's support for quotient types; quotient types are not yet in Isabelle, so for now I hardcoded "IntEx.my_int"

removed the Nitpick code that loaded the "Nitpick" theory explicitly if it's not already loaded, because this didn't work properly and is of doubtful value

Added transpose_rectangle, when the input list is rectangular.

Add transpose to the List-theory.

some examples for basic context operations;

minimal tuning of this slightly dated material;

added Subgoal.FOCUS; misc tuning and clarification;

basic setup for ML examples: tag "mlex";

union is an abbreviation for sup.
