45614  9 
* Prover IDE (PIDE) improvements: 
10 

11 
 markup for bound variables 

12 
 markup for types of term variables (e.g. displayed as tooltips) 

13 

46485  14 
* Updated and extended reference manuals ("isarref" and 
15 
"implementation"); reduced remaining material in old "ref" manual. 

16 

45593  17 
* Rule attributes in local theory declarations (e.g. locale or class) 
18 
are now statically evaluated: the resulting theorem is stored instead 

19 
of the original expression. INCOMPATIBILITY in rare situations, where 

20 
the historic accident of dynamic reevaluation in interpretations 

21 
etc. was exploited.

31 
num ~> num_token 

32 
xnum ~> xnum_token 

33 
xstr ~> str_token 

34 

35 
Minor INCOMPATIBILITY. Note that in practice "num_const" or 

36 
"num_position" etc. are mainly used instead (which also include 

37 
position information via constraints).

* Discontinued old "prems" fact, which used to refer to the accidental 
47 
collection of foundational premises in the context (marked as legacy 

48 
since Isabelle2011). 

49 

45134  50 
* Obsolete command 'types' has been discontinued. Use 'type_synonym' 
51 
instead. INCOMPATIBILITY. 

52

* Ancient code generator for SML and its commands 'code_module', 
45383  54 
'code_library', 'consts_code', 'types_code' have been discontinued.

*** HOL *** 
78 

46160  79 
* Type 'a set is now a proper type constructor (just as before 
80 
Isabelle2008). Definitions mem_def and Collect_def have disappeared. 

81 
Nontrivial INCOMPATIBILITY. For developments keeping predicates and 

82 
sets separate, it is often sufficient to rephrase sets S accidentally 

83 
used as predicates by "%x. x : S" and predicates P accidentally used 

84 
as sets by "{x. P x}". Corresponding proofs in a first step should be 

85 
pruned from any tinkering with former theorems mem_def and 

86 
Collect_def. For developments which deliberately mixed predicates and 

87 
sets, a planning step is necessary to determine what should become a 

88 
predicate and what a set. It can be helpful to carry out that step in 

89 
Isabelle20111 before jumping right into the current release.

* Quickcheck: 
300 
 Quickcheck returns variable assignments as counterexamples, which 

301 
allows to reveal the underspecification of functions under test. 

302 
For example, refuting "hd xs = x", it presents the variable 

303 
assignment xs = [] and x = a1 as a counterexample, assuming that 

304 
any property is false whenever "hd []" occurs in it. 

305 
These counterexample are marked as potentially spurious, as 

306 
Quickcheck also returns "xs = []" as a counterexample to the 

307 
obvious theorem "hd xs = hd xs". 

308 
After finding a potentially spurious counterexample, Quickcheck 

309 
continues searching for genuine ones. 

310 
By default, Quickcheck shows potentially spurious and genuine 

311 
counterexamples. The option "genuine_only" sets quickcheck to 

312 
only show genuine counterexamples. 

45941  313 

314 
 The command 'quickcheck_generator' creates random and exhaustive 

315 
value generators for a given type and operations. 

316 
It generates values by using the operations as if they were 

317 
constructors of that type.

* Improved Isabelle/jEdit Prover IDE (PIDE), which can be invoked as

"isabelle jedit" or "ISABELLE_HOME/Isabelle" on the command line. 
44760  380

 Management of multiple theory files directly from the editor 
44760  382 
buffer store  bypassing the filesystem (no requirement to save 
383 
files for checking). 

384 

44777  385 
 Markup of formal entities within the text buffer, with semantic 
44760  386 
highlighting, tooltips and hyperlinks to jump to defining source 
387 
positions. 

388 

44777  389 
 Improved text rendering, with sub/superscripts in the source 
390 
buffer (including support for copy/paste wrt. output panel, HTML 

391 
theory output and other nonIsabelle text boxes). 

392 

393 
 Refined scheduling of proof checking and printing of results, 

44760  394 
based on interactive editor view. (Note: jEdit folding and 
395 
narrowing allows to restrict buffer perspectives explicitly.) 

396 

44777  397 
 Reduced CPU performance requirements, usable on machines with few 
44760  398 
cores. 
399 

44777  400 
 Reduced memory requirements due to pruning of unused document 
44760  401

44967  630 
* Theory Complex_Main: The definition of infinite series was 
631 
generalized. Now it is defined on the type class {topological_space, 

632 
comm_monoid_add}. Hence it is useable also for extended real numbers. 

42484  633 

44908  634 
* Theory Complex_Main: The complex exponential function "expi" is now 
635 
a typeconstrained abbreviation for "exp :: complex => complex"; thus 

636 
several polymorphic lemmas about "exp" are now applicable to "expi". 

637 

44968  638 
* Code generation: 
639 

640 
 Theory Library/Code_Char_ord provides native ordering of 

641 
characters in the target language. 

642 

643 
 Commands code_module and code_library are legacy, use export_code 

644 
instead. 

645 

646 
 Method "evaluation" is legacy, use method "eval" instead. 

647 

648 
 Legacy evaluator "SML" is deactivated by default. May be 

649 
reactivated by the following theory command: 

650 

651 
setup {* Value.add_evaluator ("SML", Codegen.eval_term) *} 

652 

653 
* Declare ext [intro] by default. Rare INCOMPATIBILITY. 

654 

45088  655 
* New proof method "induction" that gives induction hypotheses the 
656 
name "IH", thus distinguishing them from further hypotheses that come 

657 
from rule induction. The latter are still called "hyps". Method 

658 
"induction" is a thin wrapper around "induct" and follows the same 

659 
syntax. 

660 

44968  661 
* Method "fastsimp" has been renamed to "fastforce", but "fastsimp" is 
662 
still available as a legacy feature for some time. 

663 

664 
* Nitpick: 

665 
 Added "need" and "total_consts" options. 

666 
 Reintroduced "show_skolems" option by popular demand. 

667 
 Renamed attribute: nitpick_def ~> nitpick_unfold. 

668 
INCOMPATIBILITY. 

669 

670 
* Sledgehammer: 

671 
 Use quasisound (and efficient) translations by default. 

672 
 Added support for the following provers: EToFoF, LEOII, 

673 
Satallax, SNARK, Waldmeister, and Z3 with TPTP syntax. 

674 
 Automatically preplay and minimize proofs before showing them if 

675 
this can be done within reasonable time. 

676 
 sledgehammer available_provers ~> sledgehammer supported_provers. 

677 
INCOMPATIBILITY. 

678 
 Added "preplay_timeout", "slicing", "type_enc", "sound", 

679 
"max_mono_iters", and "max_new_mono_instances" options. 

680 
 Removed "explicit_apply" and "full_types" options as well as "Full 

681 
Types" Proof General menu item. INCOMPATIBILITY. 

682 

683 
* Metis: 

684 
 Removed "metisF"  use "metis" instead. INCOMPATIBILITY. 

685 
 Obsoleted "metisFT"  use "metis (full_types)" instead. 

686 
INCOMPATIBILITY. 

687 

688 
* Command 'try': 

689 
 Renamed 'try_methods' and added "simp:", "intro:", "dest:", and 

690 
"elim:" options. INCOMPATIBILITY. 

691 
 Introduced 'try' that not only runs 'try_methods' but also 

692 
'solve_direct', 'sledgehammer', 'quickcheck', and 'nitpick'. 

693 

694 
* Quickcheck: 

695 
 Added "eval" option to evaluate terms for the found counterexample 

696 
(currently only supported by the default (exhaustive) tester). 

697 
 Added postprocessing of terms to obtain readable counterexamples 

698 
(currently only supported by the default (exhaustive) tester). 

699 
 New counterexample generator quickcheck[narrowing] enables 

700 
narrowingbased testing. Requires the Glasgow Haskell compiler 

701 
with its installation location defined in the Isabelle settings 

702 
environment as ISABELLE_GHC. 

703 
 Removed quickcheck tester "SML" based on the SML code generator 

704 
(formly in HOL/Library). 

705 

706 
* Function package: discontinued option "tailrec". INCOMPATIBILITY, 

707 
use 'partial_function' instead. 

708 

709 
* Theory Library/Extended_Reals replaces now the positive extended 

710 
reals found in probability theory. This file is extended by 

711 
Multivariate_Analysis/Extended_Real_Limits. 

712 

44974  713 
* Theory Library/Old_Recdef: old 'recdef' package has been moved here, 
714 
from where it must be imported explicitly if it is really required. 

715 
INCOMPATIBILITY. 

44968  716 

717 
* Theory Library/Wfrec: wellfounded recursion combinator "wfrec" has 

718 
been moved here. INCOMPATIBILITY. 

719 

720 
* Theory Library/Saturated provides type of numbers with saturated 

721 
arithmetic. 

722 

723 
* Theory Library/Product_Lattice defines a pointwise ordering for the 

724 
product type 'a * 'b, and provides instance proofs for various order 

725 
and lattice type classes. 

726 

727 
* Theory Library/Countable now provides the "countable_datatype" proof 

728 
method for proving "countable" class instances for datatypes. 

729 

730 
* Theory Library/Cset_Monad allows do notation for computable sets 

731 
(cset) via the generic monad adhoc overloading facility. 

732 

733 
* Library: Theories of common data structures are split into theories 

734 
for implementation, an invariantensuring type, and connection to an 

735 
abstract type. INCOMPATIBILITY. 

736 

737 
 RBT is split into RBT and RBT_Mapping. 

738 
 AssocList is split and renamed into AList and AList_Mapping. 

739 
 DList is split into DList_Impl, DList, and DList_Cset. 

740 
 Cset is split into Cset and List_Cset. 

741 

742 
* Theory Library/Nat_Infinity has been renamed to 

743 
Library/Extended_Nat, with name changes of the following types and 

744 
constants: 

745 

746 
type inat ~> type enat 

747 
Fin ~> enat 

748 
Infty ~> infinity (overloaded) 

749 
iSuc ~> eSuc 

750 
the_Fin ~> the_enat 

751 

752 
Every theorem name containing "inat", "Fin", "Infty", or "iSuc" has 

753 
been renamed accordingly. INCOMPATIBILITY. 

754 

755 
* Session Multivariate_Analysis: The euclidean_space type class now 

756 
fixes a constant "Basis :: 'a set" consisting of the standard 

757 
orthonormal basis for the type. Users now have the option of 

758 
quantifying over this set instead of using the "basis" function, e.g. 

759 
"ALL x:Basis. P x" vs "ALL i<DIM('a). P (basis i)". 

760 

761 
* Session Multivariate_Analysis: Type "('a, 'b) cart" has been renamed 

762 
to "('a, 'b) vec" (the syntax "'a ^ 'b" remains unaffected). Constants 

763 
"Cart_nth" and "Cart_lambda" have been respectively renamed to 

764 
"vec_nth" and "vec_lambda"; theorems mentioning those names have 

765 
changed to match. Definition theorems for overloaded constants now use 

766 
the standard "foo_vec_def" naming scheme. A few other theorems have 

767 
been renamed as follows (INCOMPATIBILITY): 

768 

769 
Cart_eq ~> vec_eq_iff 

770 
dist_nth_le_cart ~> dist_vec_nth_le 

771 
tendsto_vector ~> vec_tendstoI 

772 
Cauchy_vector ~> vec_CauchyI 

773 

774 
* Session Multivariate_Analysis: Several duplicate theorems have been 

775 
removed, and other theorems have been renamed or replaced with more 

776 
general versions. INCOMPATIBILITY.

'_type' suffix any longer (obsolete due to authentic syntax).

41571  1209 
testing. Random testing can be invoked by "quickcheck [random]", 
1210 
exhaustive testing by "quickcheck [exhaustive]". 

41398  1211 

1212 
* Quickcheck instantiates polymorphic types with small finite 

1213 
datatypes by default. This enables a simple execution mechanism to 

1214 
handle quantifiers and function equality over the finite datatypes. 

1215

INCOMPATIBILITY. 
40725  1248 
 Added support for partial quotient types. 
1249 
 Added local versions of the "Nitpick.register_xxx" functions. 

1250 
 Added "whack" option. 

1251 
 Allow registration of quotient types as codatatypes. 

1252 
 Improved "merge_type_vars" option to merge more types. 

1253 
 Removed unsound "fast_descrs" option. 

1254 
 Added custom symmetry breaking for datatypes, making it possible to reach 

1255 
higher cardinalities. 

1256 
 Prevent the expansion of too large definitions.

41571  1258 
* Proof methods "metis" and "meson" now have configuration options 
1259 
"meson_trace", "metis_trace", and "metis_verbose" that can be enabled 

1260 
to diagnose these tools. E.g. 

1261 

1262 
using [[metis_trace = true]] 

1263 

41398  1264 
* Auto Solve: Renamed "Auto Solve Direct". The tool is now available 
1265 
manually as command 'solve_direct'. 

1266 

41601  1267 
* The default SMT solver Z3 must be enabled explicitly (due to 
1268 
licensing issues) by setting the environment variable 

41603  1269 
Z3_NON_COMMERCIAL in etc/settings of the component, for example. For 
1270 
commercial applications, the SMT solver CVC3 is provided as fallback; 

1271 
changing the SMT solver is done via the configuration option 

1272 
"smt_solver".

41571  1275 
i.e. "remote_cvc3" and "remote_z3". 
1276 

1277 
* Added basic SMT support for datatypes, records, and typedefs using 

1278 
the oracle mode (no proofs). Direct support of pairs has been dropped 

1279 
in exchange (pass theorems fst_conv snd_conv pair_collapse to the SMT 

1280 
support for a similar behavior). Minor INCOMPATIBILITY.

1324 
equal and constant equal, plus renaming of related facts and various 

1325 
tuning. INCOMPATIBILITY. 

1326
