*** General *** 
11 

64390  12 
* Splitter in proof methods "simp", "auto" and friends: 
13 
 The syntax "split add" has been discontinued, use plain "split", 

14 
INCOMPATIBILITY. 

15 
 For situations with many conditional or case expressions, there is 

16 
an alternative splitting strategy that can be much faster. It is 

17 
selected by writing "split!" instead of "split". It applies safe 

18 
introduction and elimination rules after each split rule. As a 

19 
result the subgoal may be split into several subgoals. 

20 

63273  21 
* Command 'bundle' provides a local theory target to define a bundle 
22 
from the body of specification commands (such as 'declare', 

23 
'declaration', 'notation', 'lemmas', 'lemma'). For example: 

24 

25 
bundle foo 

26 
begin 

27 
declare a [simp] 

28 
declare b [intro] 

29 
end 

63272  30 

63282  31 
* Command 'unbundle' is like 'include', but works within a local theory 
32 
context. Unlike "context includes ... begin", the effect of 'unbundle' 

33 
on the target context persists, until different declarations are given. 

34 

63977  35 
* Simplified outer syntax: uniform category "name" includes long 
36 
identifiers. Former "xname" / "nameref" / "name reference" has been 

37 
discontinued. 

38 

39 
* Embedded content (e.g. the inner syntax of types, terms, props) may be 

40 
delimited uniformly via cartouches. This works better than oldfashioned 

41 
quotes when sublanguages are nested. 

42 

43 
* Mixfix annotations support general block properties, with syntax 

44 
"(\<open>x=a y=b z \<dots>\<close>". Notable property names are "indent", "consistent", 

45 
"unbreakable", "markup". The existing notation "(DIGITS" is equivalent 

46 
to "(\<open>indent=DIGITS\<close>". The former notation "(00" for unbreakable blocks 

47 
is superseded by "(\<open>unbreabable\<close>"  rare INCOMPATIBILITY. 

63650  48 

63383  49 
* Proof method "blast" is more robust wrt. corner cases of Pure 
50 
statements without objectlogic judgment. 

51 

63624
994d1a1105ef
more informative 'prf' and 'full_prf', based on HOL/Proofs/ex/XML_Data.thy;

changeset

52 
* Commands 'prf' and 'full_prf' are somewhat more informative (again): 
63977  53 
proof terms are reconstructed and cleaned from administrative thm nodes. 
54 

55 
* Code generator: config option "code_timing" triggers measurements of 

56 
different phases of code generation. See src/HOL/ex/Code_Timing.thy for 

57 
examples. 

58 

59 
* Code generator: implicits in Scala (stemming from type class 

60 
instances) are generated into companion object of corresponding type 

61 
class, to resolve some situations where ambiguities may occur. 

62 

64390  63 
* Solve direct: option "solve_direct_strict_warnings" gives explicit 
64 
warnings for lemma statements with trivial proofs. 

64013
048b7dbfdfa3

62904  67 
*** Prover IDE  Isabelle/Scala/jEdit *** 
68 

64527  69 
* More aggressive flushing of machinegenerated input, according to 
70 
system option editor_generated_input_delay (in addition to existing 

71 
editor_input_delay for regular user edits). This may affect overall PIDE 

72 
reactivity and CPU usage. 

73 

64390  74 
* Syntactic indentation according to Isabelle outer syntax. Action 
75 
"indentlines" (shortcut C+i) indents the current line according to 

76 
command keywords and some command substructure. Action 

77 
"isabelle.newline" (shortcut ENTER) indents the old and the new line 

78 
according to command keywords only; see also option 

79 
"jedit_indent_newline". 

80 

81 
* Semantic indentation for unstructured proof scripts ('apply' etc.) via 

82 
number of subgoals. This requires information of ongoing document 

83 
processing and may thus lag behind, when the user is editing too 

84 
quickly; see also option "jedit_script_indent" and 

85 
"jedit_script_indent_limit". 

86 

87 
* Refined folding mode "isabelle" based on Isar syntax: 'next' and 'qed' 

88 
are treated as delimiters for fold structure; 'begin' and 'end' 

89 
structure of theory specifications is treated as well. 

90 

91 
* Command 'proof' provides information about proof outline with cases, 

92 
e.g. for proof methods "cases", "induct", "goal_cases". 

93 

94 
* Completion templates for commands involving "begin ... end" blocks, 

95 
e.g. 'context', 'notepad'. 

96 

97 
* Sidekick parser "isabellecontext" shows nesting of context blocks 

98 
according to 'begin' and 'end' structure. 

99 

63977  100 
* Highlighting of entity def/ref positions wrt. cursor. 
101 

102 
* Action "isabelle.selectentity" (shortcut CS+ENTER) selects all 

64514  103 
occurrences of the formal entity at the caret position. This facilitates 
63977  104 
systematic renaming. 
105 

106 
* PIDE document markup works across multiple Isar commands, e.g. the 

107 
results established at the end of a proof are properly identified in the 

108 
theorem statement. 

109 

110 
* Cartouche abbreviations work both for " and ` to accomodate typical 

111 
situations where old ASCII notation may be updated. 

112 

63875  113 
* Dockable window "Symbols" also provides access to 'abbrevs' from the 
114 
outer syntax of the current theory buffer. This provides clickable 

115 
syntax templates, including entries with empty abbrevs name (which are 

116 
inaccessible via keyboard completion). 

117 

63022  118 
* IDE support for the Isabelle/Pure bootstrap process, with the 
119 
following independent stages: 

120 

121 
src/Pure/ROOT0.ML 

122 
src/Pure/ROOT.ML 

123 
src/Pure/Pure.thy 

124 
src/Pure/ML_Bootstrap.thy 

125 

126 
The ML ROOT files act like quasitheories in the context of theory 

127 
ML_Bootstrap: this allows continuous checking of all loaded ML files. 

128 
The theory files are presented with a modified header to import Pure 

129 
from the running Isabelle instance. Results from changed versions of 

130 
each stage are *not* propagated to the next stage, and isolated from the 

131 
actual Isabelle/Pure that runs the IDE itself. The sequential 

63307  132 
dependencies of the above files are only observed for batch build. 
62904  133 

63977  134 
* Isabelle/ML and Standard ML files are presented in Sidekick with the 
135 
tree structure of section headings: this special comment format is 

136 
described in "implementation" chapter 0, e.g. (*** section ***). 

63461  137 

63581  138 
* Additional abbreviations for syntactic completion may be specified 
63871  139 
within the theory header as 'abbrevs'. The theory syntax for 'keywords' 
140 
has been simplified accordingly: optional abbrevs need to go into the 

141 
new 'abbrevs' section. 

142 

143 
* Global abbreviations via $ISABELLE_HOME/etc/abbrevs and 

144 
$ISABELLE_HOME_USER/etc/abbrevs are no longer supported. Minor 

145 
INCOMPATIBILITY, use 'abbrevs' within theory header instead. 

63579  146 

64390  147 
* Action "isabelle.keymapmerge" asks the user to resolve pending 
148 
Isabelle keymap changes that are in conflict with the current jEdit 

149 
keymap; nonconflicting changes are always applied implicitly. This 

150 
action is automatically invoked on Isabelle/jEdit startup and thus 

151 
increases chances that users see new keyboard shortcuts when reusing 

152 
old keymaps. 

153 

63675  154 
* ML and document antiquotations for filesystems paths are more uniform 
155 
and diverse: 

156 

157 
@{path NAME}  no filesystem check 

158 
@{file NAME}  check for plain file 

159 
@{dir NAME}  check for directory 

160 

161 
Minor INCOMPATIBILITY, former uses of @{file} and @{file_unchecked} may 

162 
have to be changed. 

63669  163 

164 

63977  165 
*** Document preparation *** 
166 

167 
* New symbol \<circle>, e.g. for temporal operator. 

168 

64073  169 
* New document and ML antiquotation @{locale} for locales, similar to 
170 
existing antiquotation @{class}. 

171 

63977  172 
* Mixfix annotations support delimiters like \<^control>\<open>cartouche\<close>  
173 
this allows special forms of document output. 

174 

175 
* Raw LaTeX output now works via \<^latex>\<open>...\<close> instead of raw control 

176 
symbol \<^raw:...>. INCOMPATIBILITY, notably for LaTeXsugar.thy and its 

177 
derivatives. 

178 

179 
* \<^raw:...> symbols are no longer supported. 

180 

181 
* Old 'header' command is no longer supported (legacy since 

182 
Isabelle2015).

63039  197 
* Command 'define' introduces a local (nonpolymorphic) definition, with 
198 
optional abstraction over local parameters. The syntax resembles 

63043  199 
'definition' and 'obtain'. It fits better into the Isar language than 
200 
old 'def', which is now a legacy feature.

* The defining position of a literal fact \<open>prop\<close> is maintained more 
209 
carefully, and made accessible as hyperlink in the Prover IDE. 

210 

211 
* Commands 'finally' and 'ultimately' used to expose the result as 

212 
literal fact: this accidental behaviour has been discontinued. Rare 

213 
INCOMPATIBILITY, use more explicit means to refer to facts in Isar. 

214 

215 
* Command 'axiomatization' has become more restrictive to correspond 

216 
better to internal axioms as singleton facts with mandatory name. Minor 

217 
INCOMPATIBILITY. 

62939  218 

63259  219 
* Proof methods may refer to the main facts via the dynamic fact 
220 
"method_facts". This is particularly useful for Eisbach method 

221 
definitions. 

222 

63527  223 
* Proof method "use" allows to modify the main facts of a given method 
224 
expression, e.g. 

63259  225 

226 
(use facts in simp) 

227 
(use facts in \<open>simp add: ...\<close>) 

228 

63977  229 
* The old proof method "default" has been removed (legacy since 
230 
Isabelle2016). INCOMPATIBILITY, use "standard" instead.

234 

63977  235 
* Pure provides basic versions of proof methods "simp" and "simp_all" 
236 
that only know about metaequality (==). Potential INCOMPATIBILITY in 

237 
theory imports that merge Pure with e.g. Main of Isabelle/HOL: the order 

238 
is relevant to avoid confusion of Pure.simp vs. HOL.simp. 

239 

240 
* The command 'unfolding' and proof method "unfold" include a second 

241 
stage where given equations are passed through the attribute "abs_def" 

242 
before rewriting. This ensures that definitions are fully expanded, 

243 
regardless of the actual parameters that are provided. Rare 

244 
INCOMPATIBILITY in some corner cases: use proof method (simp only:) 

245 
instead, or declare [[unfold_abs_def = false]] in the proof context. 

246 

247 
* Typeinference improves sorts of newly introduced type variables for 

248 
the objectlogic, using its base sort (i.e. HOL.type for Isabelle/HOL). 

249 
Thus terms like "f x" or "\<And>x. P x" without any further syntactic context 

250 
produce x::'a::type in HOL instead of x::'a::{} in Pure. Rare 

251 
INCOMPATIBILITY, need to provide explicit type constraints for Pure 

252 
types where this is really intended.

63977  257 
* New proof method "argo" using the builtin Argo solver based on SMT 
258 
technology. The method can be used to prove goals of quantifierfree 

259 
propositional logic, goals based on a combination of quantifierfree 

260 
propositional logic with equality, and goals based on a combination of 

261 
quantifierfree propositional logic with linear real arithmetic 

262 
including min/max/abs. See HOL/ex/Argo_Examples.thy for examples.

265

276 
them in "~~/src/HOL/Library/BNF_Corec.thy": 'corec', 'corecursive', 

277 
'friend_of_corec', and 'corecursion_upto'; and 'corec_unique' proof

 'primrec' now allows nested calls through the predicator in addition

63855  283 
 'bnf' automatically discharges reflexive proof obligations. 
62693  284 
 'bnf' outputs a slightly modified proof obligation expressing rel in

terms of map and set 
63855  286 
(not giving a specification for rel makes this one reflexive). 
62693  287 
 'bnf' outputs a new proof obligation expressing pred in terms of set 
63855  288 
(not giving a specification for pred makes this one reflexive). 
289 
INCOMPATIBILITY: manual 'bnf' declarations may need adjustment. 

62335  290 
 Renamed lemmas: 
291

* The 'coinductive' command produces a proper coinduction rule for 
300 
mutual coinductive predicates. This new rule replaces the old rule, 

301 
which exposed details of the internal fixpoint construction and was 

302 
hard to use. INCOMPATIBILITY. 

303 

304 
* New abbreviations for negated existence (but not bounded existence): 

305 

306 
\<nexists>x. P x \<equiv> \<not> (\<exists>x. P x) 

307 
\<nexists>!x. P x \<equiv> \<not> (\<exists>!x. P x) 

308 

309 
* The print mode "HOL" for ASCII syntax of binders "!", "?", "?!", "@" 

310 
has been removed for output. It is retained for input only, until it is 

311 
eliminated altogether. 

312 

313 
* The unique existence quantifier no longer provides 'binder' syntax, 

314 
but uses syntax translations (as for bounded unique existence). Thus 

315 
iterated quantification \<exists>!x y. P x y with its slightly confusing 

316 
sequential meaning \<exists>!x. \<exists>!y. P x y is no longer possible. Instead, 

317 
pattern abstraction admits simultaneous unique existence \<exists>!(x, y). P x y 

318 
(analogous to existing notation \<exists>!(x, y)\<in>A. P x y). Potential 

319 
INCOMPATIBILITY in rare situations. 

320 

321 
* Conventional syntax "%(). t" for unit abstractions. Slight syntactic 

322 
INCOMPATIBILITY.

listsum ~> sum_list

343 
div_mult_self2_is_id ~> nonzero_mult_div_cancel_right 

344

365 
* New type class "idom_abs_sgn" specifies algebraic properties 

366 
of sign and absolute value functions. Type class "sgn_if" has 

367 
disappeared. Slight INCOMPATIBILITY. 

368 

369 
* Dedicated syntax LENGTH('a) for length of types. 

370 

63977  371 
* Characters (type char) are modelled as finite algebraic type 
372 
corresponding to {0..255}. 

373 

374 
 Logical representation: 

375 
* 0 is instantiated to the ASCII zero character. 

376 
* All other characters are represented as "Char n" 

377 
with n being a raw numeral expression less than 256. 

378 
* Expressions of the form "Char n" with n greater than 255 

379 
are noncanonical. 

380 
 Printing and parsing: 

381 
* Printable characters are printed and parsed as "CHR ''\<dots>''" 

382 
(as before). 

383 
* The ASCII zero character is printed and parsed as "0". 

384 
* All other canonical characters are printed as "CHR 0xXX" 

385 
with XX being the hexadecimal character code. "CHR n" 

386 
is parsable for every numeral expression n. 

387 
* Noncanonical characters have no special syntax and are 

388 
printed as their logical representation. 

389 
 Explicit conversions from and to the natural numbers are 

390 
provided as char_of_nat, nat_of_char (as before). 

391 
 The auxiliary nibble type has been discontinued. 

392 

393 
INCOMPATIBILITY. 

394 

395 
* Type class "div" with operation "mod" renamed to type class "modulo" 

396 
with operation "modulo", analogously to type class "divide". This 

397 
eliminates the need to qualify any of those names in the presence of 

398 
infix "mod" syntax. INCOMPATIBILITY. 

399 

63979  400 
* Statements and proofs of KnasterTarski fixpoint combinators lfp/gfp 
401 
have been clarified. The fixpoint properties are lfp_fixpoint, its 

402 
symmetric lfp_unfold (as before), and the duals for gfp. Auxiliary items 

403 
for the proof (lfp_lemma2 etc.) are no longer exported, but can be 

404 
easily recovered by composition with eq_refl. Minor INCOMPATIBILITY. 

405 

63977  406 
* Constant "surj" is a mere input abbreviation, to avoid hiding an 
407 
equation in term output. Minor INCOMPATIBILITY. 

408 

409 
* Command 'code_reflect' accepts empty constructor lists for datatypes, 

410 
which renders those abstract effectively. 

411 

412 
* Command 'export_code' checks given constants for abstraction 

413 
violations: a small guarantee that given constants specify a safe 

414 
interface for the generated code. 

415 

416 
* Code generation for Scala: ambiguous implicts in class diagrams are 

417 
spelt out explicitly. 

418 

419 
* Static evaluators (Code_Evaluation.static_* in Isabelle/ML) rely on 

420 
explicitly provided auxiliary definitions for required type class 

64390  421 
dictionaries rather than halfworking magic. INCOMPATIBILITY, see the 
422 
tutorial on code generation for details. 

423 

424 
* Theory Set_Interval: substantial new theorems on indexed sums and 

425 
products. 

63977  426 

427 
* Locale bijection establishes convenient default simp rules such as 

428 
"inv f (f a) = a" for total bijections. 

429 

430 
* Abstract locales semigroup, abel_semigroup, semilattice, 

431 
semilattice_neutr, ordering, ordering_top, semilattice_order, 

432 
semilattice_neutr_order, comm_monoid_set, semilattice_set, 

433 
semilattice_neutr_set, semilattice_order_set, 

434 
semilattice_order_neutr_set monoid_list, comm_monoid_list, 

435 
comm_monoid_list_set, comm_monoid_mset, comm_monoid_fun use boldified 

436 
syntax uniformly that does not clash with corresponding global syntax. 

437 
INCOMPATIBILITY. 

438 

439 
* Former locale lifting_syntax is now a bundle, which is easier to 

440 
include in a local context or theorem statement, e.g. "context includes 

441 
lifting_syntax begin ... end". Minor INCOMPATIBILITY. 

442 

63807  443 
* Some old / obsolete theorems have been renamed / removed, potential 
444 
INCOMPATIBILITY. 

445 

446 
nat_less_cases  removed, use linorder_cases instead 

447 
inv_image_comp  removed, use image_inv_f_f instead 

448

493 

494 
* The type class ordered_comm_monoid_add is now called 

495 
ordered_cancel_comm_monoid_add. A new type class ordered_comm_monoid_add 

496 
is introduced as the combination of ordered_ab_semigroup_add +

* Renamed HOL/Quotient_Examples/FSet.thy to 
63977  600 
HOL/Quotient_Examples/Quotient_FSet.thy INCOMPATIBILITY. 
601 

64390  602 
* Session HOLLibrary: theory FinFun bundles "finfun_syntax" and 
603 
"no_finfun_syntax" allow to control optional syntax in local contexts; 

604 
this supersedes former theory FinFun_Syntax. INCOMPATIBILITY, e.g. use 

605 
"unbundle finfun_syntax" to imitate import of 

606 
"~~/src/HOL/Library/FinFun_Syntax". 

607 

608 
* Session HOLLibrary: theory Multiset_Permutations (executably) defines 

609 
the set of permutations of a given set or multiset, i.e. the set of all 

610 
lists that contain every element of the carrier (multi)set exactly 

611 
once. 

612 

613 
* Session HOLLibrary: multiset membership is now expressed using 

614 
set_mset rather than count. 

615 

616 
 Expressions "count M a > 0" and similar simplify to membership 

617 
by default. 

618 

619 
 Converting between "count M a = 0" and nonmembership happens using 

620 
equations count_eq_zero_iff and not_in_iff. 

621 

622 
 Rules count_inI and in_countE obtain facts of the form 

623 
"count M a = n" from membership. 

624 

625 
 Rules count_in_diffI and in_diff_countE obtain facts of the form 

626 
"count M a = n + count N a" from membership on difference sets. 

627 

628 
INCOMPATIBILITY. 

629 

630 
* Session HOLLibrary: theory LaTeXsugar uses newstyle "dummy_pats" for 

631 
displaying equations in functional programming style  variables 

632 
present on the lefthand but not on the righhand side are replaced by 

633 
underscores. 

634 

635 
* Session HOLLibrary: theory Combinator_PER provides combinator to 

636 
build partial equivalence relations from a predicate and an equivalence 

637 
relation. 

638 

639 
* Session HOLLibrary: theory Perm provides basic facts about almost 

640 
everywhere fix bijections. 

641 

642 
* Session HOLLibrary: theory Normalized_Fraction allows viewing an 

643 
element of a field of fractions as a normalized fraction (i.e. a pair of 

644 
numerator and denominator such that the two are coprime and the 

645 
denominator is normalized wrt. unit factors). 

646 

647 
* Session HOLNSA has been renamed to HOLNonstandard_Analysis. 

648 

649 
* Session HOLMultivariate_Analysis has been renamed to HOLAnalysis. 

650 

651 
* Session HOLAnalysis: measure theory has been moved here from 

652 
HOLProbability. When importing HOLAnalysis some theorems need 

653 
additional name spaces prefixes due to name clashes. INCOMPATIBILITY. 

654 

655 
* Session HOLAnalysis: more complex analysis including Cauchy's 

656 
inequality, Liouville theorem, open mapping theorem, maximum modulus 

657 
principle, Residue theorem, Schwarz Lemma. 

658 

659 
* Session HOLAnalysis: Theory of polyhedra: faces, extreme points, 

660 
polytopes, and the Kreinâ€“Milman Minkowski theorem. 

661 

662 
* Session HOLAnalysis: Numerous results ported from the HOL Light 

663 
libraries: homeomorphisms, continuous function extensions, invariance of 

664 
domain. 

665 

666 
* Session HOLProbability: the type of emeasure and nn_integral was 

667 
changed from ereal to ennreal, INCOMPATIBILITY. 

668 

669 
emeasure :: 'a measure \<Rightarrow> 'a set \<Rightarrow> ennreal 

670 
nn_integral :: 'a measure \<Rightarrow> ('a \<Rightarrow> ennreal) \<Rightarrow> ennreal 

671 

672 
* Session HOLProbability: Code generation and QuickCheck for 

673 
Probability Mass Functions. 

674 

675 
* Session HOLProbability: theory Random_Permutations contains some 

676 
theory about choosing a permutation of a set uniformly at random and 

677 
folding over a list in random order. 

678 

679 
* Session HOLProbability: theory SPMF formalises discrete 

680 
subprobability distributions. 

681 

682 
* Session HOLLibrary: the names of multiset theorems have been 

683 
normalised to distinguish which ordering the theorems are about 

684

ms_lesseq_impl > subset_eq_mset_impl 

710 

711 
* HOLLibrary: multisets are now ordered with the multiset ordering 

712 
#\<subseteq># ~> \<le>

#\<subset># ~> < 

714 
le_multiset ~> less_eq_multiset 

715 
less_multiset ~> le_multiset 

716 
INCOMPATIBILITY. 

717 

718 
* Session HOLLibrary: the prefix multiset_order has been discontinued: 

719 
the theorems can be directly accessed. As a consequence, the lemmas 

720 
"order_multiset" and "linorder_multiset" have been discontinued, and the 

721 
interpretations "multiset_linorder" and "multiset_wellorder" have been 

722 
replaced by instantiations. INCOMPATIBILITY. 

723 

724

749 

750 
* Session HOLLibrary: the lemma mset_map has now the attribute [simp]. 

751 
INCOMPATIBILITY. 

752 

753 
* Session HOLLibrary: some theorems about multisets have been removed. 

754 
INCOMPATIBILITY, use the following replacements: 

755 

756 
le_multiset_plus_plus_left_iff ~> add_less_cancel_right 

757

772 
mset_less_empty_nonempty ~> subset_mset.zero_less_iff_neq_zero 

773 

774 
* Session HOLLibrary: some typeclass constraints about multisets have 

775 
been reduced from ordered or linordered to preorder. Multisets have the 

776 
additional typeclasses order_bot, no_top, 

777 
ordered_ab_semigroup_add_imp_le, ordered_cancel_comm_monoid_add, 

778 
linordered_cancel_ab_semigroup_add, and 

779 
ordered_ab_semigroup_monoid_add_imp_le. INCOMPATIBILITY. 

780 

781 
* Session HOLLibrary: there are some new simplification rules about 

782 
multisets, the multiset ordering, and the subset ordering on multisets. 

783 
INCOMPATIBILITY. 

784 

785 
* Session HOLLibrary: the subset ordering on multisets has now the 

786 
interpretations ordered_ab_semigroup_monoid_add_imp_le and 

787 
bounded_lattice_bot. INCOMPATIBILITY. 

788 

789 
* Session HOLLibrary, theory Multiset: single has been removed in favor 

790 
of add_mset that roughly corresponds to Set.insert. Some theorems have 

791 
removed or changed: 

792 

793 
single_not_empty ~> add_mset_not_empty or empty_not_add_mset 

794 
fold_mset_insert ~> fold_mset_add_mset

844 

845 
* Session HOLLibrary, theory Multiset: the definitions of some 

846 
constants have changed to use add_mset instead of adding a single 

847 
element: 

848 

849

857 
INCOMPATIBILITY. 

858 

859 
* Session HOLLibrary, theory Multiset: due to the above changes, the 

860 
attributes of some multiset theorems have been changed: 

861 

862 
insert_DiffM [] ~> [simp] 

863 
insert_DiffM2 [simp] ~> [] 

864 
diff_add_mset_swap [simp]

881 
INCOMPATIBILITY. 

882 

64391  883 
* Session HOLLibrary, theory Multiset: the order of the variables in 
64390  884 
the second cases of multiset_induct, multiset_induct2_size, 
885 
multiset_induct2 has been changed (e.g. Add A a ~> Add a A). 

886 
INCOMPATIBILITY. 

887 

888 
* Session HOLLibrary, theory Multiset: there is now a simplification 

889 
procedure on multisets. It mimics the behavior of the procedure on 

890 
natural numbers. INCOMPATIBILITY. 

891 

892 
* Session HOLLibrary, theory Multiset: renamed sums and products of 

893 
multisets: 

894 

895 
msetsum ~> sum_mset 

896 
msetprod ~> prod_mset 

897 

898 
* Session HOLLibrary, theory Multiset: the notation for intersection 

899 
and union of multisets have been changed: 

900 

901 
#\<inter> ~> \<inter># 

902 
#\<union> ~> \<union># 

903 

904 
INCOMPATIBILITY. 

905 

906 
* Session HOLLibrary, theory Multiset: the lemma 

907 
one_step_implies_mult_aux on multisets has been removed, use 

908 
one_step_implies_mult instead. INCOMPATIBILITY. 

909 

910 
* Session HOLLibrary: theory Complete_Partial_Order2 provides reasoning 

911 
support for monotonicity and continuity in chaincomplete partial orders 

912 
and about admissibility conditions for fixpoint inductions. 

913 

64523  914 
* Session HOLLibrary: theory Library/Polynomial contains also 
915 
derivation of polynomials (formerly in Library/Poly_Deriv) but not 

916 
gcd/lcm on polynomials over fields. This has been moved to a separate 

917 
theory Library/Polynomial_GCD_euclidean.thy, to pave way for a possible 

918 
future different type class instantiation for polynomials over factorial 

919 
rings. INCOMPATIBILITY. 

64390  920 

921 
* Session HOLLibrary: theory Sublist provides function "prefixes" with 

922 
the following renaming 

923 

924 
prefixeq > prefix 

925 
prefix > strict_prefix 

926 
suffixeq > suffix 

927 
suffix > strict_suffix 

928 

929 
Added theory of longest common prefixes. 

64389  930 

64391  931 
* Session HOLNumber_Theory: algebraic foundation for primes: 
932 
Generalisation of predicate "prime" and introduction of predicates 

933 
"prime_elem", "irreducible", a "prime_factorization" function, and the 

934 
"factorial_ring" typeclass with instance proofs for nat, int, poly. Some 

935 
theorems now have different names, most notably "prime_def" is now 

936 
"prime_nat_iff". INCOMPATIBILITY. 

937 

938 
* Session Old_Number_Theory has been removed, after porting remaining 

939 
theories. 

940 

64551  941 
* Session HOLTypes_To_Sets provides an experimental extension of 
942 
HigherOrder Logic to allow translation of types to sets.

63215  954 
Isabelle/ML, with special notation @int/nat or @int for numerals (an 
955 
abbreviation for antiquotation @{Pure.rat argument}) and ML pretty

962 
the argument is a plain file. Minor INCOMPATIBILITY. 

963 

964 
* Antiquotation @{make_string} is available during Pure bootstrap  

965 
with approximative output quality. 

966 

967 
* Lowlevel ML system structures (like PolyML and RunCall) are no longer 

968 
exposed to Isabelle/ML userspace. Potential INCOMPATIBILITY. 

969 

62861  970 
* The ML function "ML" provides easy access to runtime compilation. 
971 
This is particularly useful for conditional compilation, without 

972 
requiring separate files. 

973 

62498  974 
* Option ML_exception_debugger controls detailed exception trace via the 
975 
Poly/ML debugger. Relevant ML modules need to be compiled beforehand 

976 
with ML_file_debug, or with ML_file and option ML_debugger enabled. Note 

977 
debugger information requires consirable time and space: main 

978 
Isabelle/HOL with full debugger support may need ML_system_64. 

979 

62514  980 
* Local_Theory.restore has been renamed to Local_Theory.reset to 
981 
emphasize its disruptive impact on the cumulative context, notably the 

982 
scope of 'private' or 'qualified' names. Note that Local_Theory.reset is 

983 
only appropriate when targets are managed, e.g. starting from a global 

984 
theory and returning to it. Regular definitional packages should use 

985 
balanced blocks of Local_Theory.open_target versus 

986 
Local_Theory.close_target instead. Rare INCOMPATIBILITY. 

987 

62519  988 
* Structure TimeLimit (originally from the SML/NJ library) has been 
989 
replaced by structure Timeout, with slightly different signature. 

990 
INCOMPATIBILITY. 

991 

62551  992 
* Discontinued cd and pwd operations, which are not welldefined in a 
993 
multithreaded environment. Note that files are usually located 

994 
relatively to the master directory of a theory (see also 

995 
File.full_path). Potential INCOMPATIBILITY. 

996

* Commandline tool "isabelle yxml" has been discontinued. 

1053 
INCOMPATIBILITY, use operations from the modules "XML" and "YXML" in 

1054 
Isabelle/ML or Isabelle/Scala. 

1055 

1056 
* Many Isabelle tools that require a Java runtime system refer to the 

1057 
settings ISABELLE_TOOL_JAVA_OPTIONS32 / ISABELLE_TOOL_JAVA_OPTIONS64, 

1058 
depending on the underlying platform. The settings for "isabelle build" 

1059 
ISABELLE_BUILD_JAVA_OPTIONS32 / ISABELLE_BUILD_JAVA_OPTIONS64 have been 

1060 
discontinued. Potential INCOMPATIBILITY. 

1061 

1062 
* The Isabelle system environment always ensures that the main 

1063 
executables are found within the shell search $PATH: "isabelle" and 

1064 
"isabelle_scala_script". 

1065 

1066 
* Isabelle tools may consist of .scala files: the Scala compiler is 

1067 
invoked on the spot. The source needs to define some object that extends 

1068 
Isabelle_Tool.Body. 

1069 

1070 
* File.bash_string, File.bash_path etc. represent Isabelle/ML and 

1071 
Isabelle/Scala strings authentically within GNU bash. This is useful to 

1072 
produce robust shell scripts under program control, without worrying 

1073 
about spaces or special characters. Note that user output works via 

1074 
Path.print (ML) or Path.toString (Scala). INCOMPATIBILITY, the old (and 

1075 
less versatile) operations File.shell_quote, File.shell_path etc. have 

1076 
been discontinued. 

1077 

63995  1078 
* The isabelle_java executable allows to run a Java process within the 
1079 
name space of Java and Scala components that are bundled with Isabelle, 

1080 
but without the Isabelle settings environment. 

1081 

64390  1082 
* Isabelle/Scala: the SSH module supports ssh and sftp connections, for 
1083 
remote commandexecution and filesystem access. This resembles 

1084 
operations from module File and Isabelle_System to some extent. Note 

1085 
that Path specifications need to be resolved remotely via 

1086 
ssh.remote_path instead of File.standard_path: the implicit process 

1087 
environment is different, Isabelle settings are not available remotely. 

1088 

1089 
* Isabelle/Scala: the Mercurial module supports repositories via the 

1090 
regular hg commandline interface. The repositroy clone and working 

1091 
directory may reside on a local or remote filesystem (via ssh 

1092 
connection).

1130

1131

schematic_lemma ~> schematic_goal 

1136 
schematic_theorem ~> schematic_goal

Commandline tool "isabelle update_theorems" updates theory sources

1154 
'ML_file_debug', 'ML_file_no_debug', 'SML_file_debug', 

1155 
'SML_file_no_debug' control compilation of sources with or without 

1156 
debugging information. The Debugger panel allows to set breakpoints (via 

1157

1158 
expressions etc. At least one Debugger view needs to be active to have 

1159

action "isabelle.updatestate" (shortcut S+ENTER) triggers manual 

1164

61729  1165 

1166 
* The Output panel no longer shows proof state output by default, to 

1167 
avoid GUI overcrowding. INCOMPATIBILITY, use the State panel instead or 

1168 
enable option "editor_output_state". 

61215  1169 

61803  1170 
* The text overview column (status of errors, warnings etc.) is updated 
1171 
asynchronously, leading to much better editor reactivity. Moreover, the 

1172 
full document node content is taken into account. The width of the 

1173 
column is scaled according to the main text area font, for improved 

1174 
visibility. 

1175 

1176 
* The main text area no longer changes its color hue in outdated 

1177 
situations. The text overview column takes over the role to indicate 

1178 
unfinished edits in the PIDE pipeline. This avoids flashing text display 

1179 
due to adhoc updates by auxiliary GUI components, such as the State 

1180

'text' (with antiquotations and control symbols). The key difference is 

1232 
the lack of the surrounding isabelle markup environment in output. 

1233 

1234 
* Text is structured in paragraphs and nested lists, using notation that 

1235 
is similar to Markdown. The control symbols for list items are as 

1236 
follows: 

1237 

1238 
\<^item> itemize 

1239 
\<^enum> enumerate

that is a cartouche: \<^name>\<open>...\<close> is equivalent to @{name \<open>...\<close>} and 
61595  1244 
\<open>...\<close> without control symbol is equivalent to @{cartouche \<open>...\<close>}. 
1245 
\<^name> without following cartouche is equivalent to @{name}. The 

61501  1246 
standard Isabelle fonts provide glyphs to render important control 
1247 
symbols, e.g. "\<^verbatim>", "\<^emph>", "\<^bold>".

The local assumptions are bound to the name "that". The result is

corresponds to a raw proof block like this:

61733  1315 
* Assumptions ('assume', 'presume') allow structured rule statements 
1316 
using 'if' and 'for', similar to 'have' etc. above. For example: 

61658  1317 

1318 
assume result: "C x y" 

1319 
if "A x" and "B y" 

1320 
for x :: 'a and y :: 'a 

1321 

1322 
This assumes "\<And>x y::'a. A x \<Longrightarrow> B y \<Longrightarrow> C x y" and produces a general 

1323 
result as usual: "A ?x \<Longrightarrow> B ?y \<Longrightarrow> C ?x ?y". 

1324 

1325 
Vacuous quantification in assumptions is omitted, i.e. a forcontext 

1326 
only effects propositions according to actual use of variables. For 

1327 
example: 

1328 

1329 
assume "A x" and "B y" for x and y 

1330 

1331 
is equivalent to: 

1332 

1333 
assume "\<And>x. A x" and "\<And>y. B y" 

1334 

60595  1335 
* The meaning of 'show' with Pure rule statements has changed: premises 
1336 
are treated in the sense of 'assume', instead of 'presume'. This means, 

62205  1337 
a goal like "\<And>x. A x \<Longrightarrow> B x \<Longrightarrow> C x" can be solved completely as 
1338 
follows: 

60595  1339 

1340 
show "\<And>x. A x \<Longrightarrow> B x \<Longrightarrow> C x" 

1341 

1342 
or: 

1343 

1344 
show "C x" if "A x" "B x" for x 

1345 

1346 
Rare INCOMPATIBILITY, the old behaviour may be recovered as follows: 

1347 

1348 
show "C x" when "A x" "B x" for x 

1349 

60459  1350 
* New command 'consider' states rules for generalized elimination and 
1351 
case splitting. This is like a toplevel statement "theorem obtains" used 

1352 
within a proof body; or like a multibranch 'obtain' without activation 

1353 
of the local context elements yet. 

1354 

60455  1355 
* Proof method "cases" allows to specify the rule as first entry of 
1356 
chained facts. This is particularly useful with 'consider': 

1357 

1358 
consider (a) A  (b) B  (c) C <proof> 

1359 
then have something 

1360 
proof cases 

1361 
case a 

1362 
then show ?thesis <proof> 

1363 
next 

1364 
case b 

1365 
then show ?thesis <proof> 

1366

1367 
case c 

1368 
then show ?thesis <proof>

qed 

1370 

60565  1371 
* Command 'case' allows fact name and attribute specification like this: 
1372 

1373 
case a: (c xs) 

1374 
case a [attributes]: (c xs) 

1375 

1376 
Facts that are introduced by invoking the case context are uniformly 

1377 
qualified by "a"; the same name is used for the cumulative fact. The old 

1378 
form "case (c xs) [attributes]" is no longer supported. Rare 

1379 
INCOMPATIBILITY, need to adapt uses of case facts in exotic situations, 

1380 
and always put attributes in front.

1390
