 the predicator :: ('a => bool) => 'a F => bool is now a firstclass 
20 
citizen in bounded natural functors 

62327  21 
 "primrec" now allows nested calls through the predicator in addition 
22 
to the map function. 

62332  23 
 "bnf" automatically discharges reflexive proof obligations 
24 
"bnf" outputs a slightly modified proof obligation expressing rel in 

25 
terms of map and set 

26 
(not giving a specification for rel makes this one reflexive) 

27 
"bnf" outputs a new proof obligation expressing pred in terms of set 

28 
(not giving a specification for pred makes this one reflexive) 

29 
INCOMPATIBILITY: manual "bnf" declarations may need adjustment 

62335  30 
 Renamed lemmas: 
31 
rel_prod_apply ~> rel_prod_inject 

32 
pred_prod_apply ~> pred_prod_inject

* IDE support for the sourcelevel debugger of Poly/ML, to work with 
62253  216 
Isabelle/ML and official Standard ML. Option "ML_debugger" and commands 
217 
'ML_file_debug', 'ML_file_no_debug', 'SML_file_debug', 

218 
'SML_file_no_debug' control compilation of sources with or without 

219 
debugging information. The Debugger panel allows to set breakpoints (via 

220 
context menu), step through stopped threads, evaluate local ML 

221 
expressions etc. At least one Debugger view needs to be active to have 

222 
any effect on the running ML program.

* The State panel manages explicit proof state output, with dynamic 
225 
autoupdate according to cursor movement. Alternatively, the jEdit 

226 
action "isabelle.updatestate" (shortcut S+ENTER) triggers manual 

227 
update. 

61729  228 

229 
* The Output panel no longer shows proof state output by default, to 

230 
avoid GUI overcrowding. INCOMPATIBILITY, use the State panel instead or 

231 
enable option "editor_output_state". 

61215  232 

61803  233 
* The text overview column (status of errors, warnings etc.) is updated 
234 
asynchronously, leading to much better editor reactivity. Moreover, the 

235 
full document node content is taken into account. The width of the 

236 
column is scaled according to the main text area font, for improved 

237 
visibility. 

238 

239 
* The main text area no longer changes its color hue in outdated 

240 
situations. The text overview column takes over the role to indicate 

241 
unfinished edits in the PIDE pipeline. This avoids flashing text display 

242 
due to adhoc updates by auxiliary GUI components, such as the State 

243 
panel.

* Commands 'paragraph' and 'subparagraph' provide additional section

292 

293 
* Command 'text_raw' has been clarified: input text is processed as in 

294 
'text' (with antiquotations and control symbols). The key difference is 

295 
the lack of the surrounding isabelle markup environment in output. 

296 

297 
* Text is structured in paragraphs and nested lists, using notation that 

298 
is similar to Markdown. The control symbols for list items are as 

299

that is a cartouche: \<^name>\<open>...\<close> is equivalent to @{name \<open>...\<close>} and 
61595  307

308 
\<^name> without following cartouche is equivalent to @{name}. The

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

363 

60449  364 
The local assumptions are bound to the name "that". The result is 
365 
exported from context of the statement as usual. The above roughly 

60414  366 
corresponds to a raw proof block like this: 
367 

368

377 

61733  378 
* Assumptions ('assume', 'presume') allow structured rule statements 
379 
using 'if' and 'for', similar to 'have' etc. above. For example: 

61658  380 

381 
assume result: "C x y" 

382 
if "A x" and "B y" 

383 
for x :: 'a and y :: 'a 

384 

385 
This assumes "\<And>x y::'a. A x \<Longrightarrow> B y \<Longrightarrow> C x y" and produces a general 

386 
result as usual: "A ?x \<Longrightarrow> B ?y \<Longrightarrow> C ?x ?y". 

387 

388 
Vacuous quantification in assumptions is omitted, i.e. a forcontext 

389 
only effects propositions according to actual use of variables. For 

390 
example: 

391 

392 
assume "A x" and "B y" for x and y 

393 

394 
is equivalent to: 

395 

396 
assume "\<And>x. A x" and "\<And>y. B y" 

397 

60595  398 
* The meaning of 'show' with Pure rule statements has changed: premises 
399 
are treated in the sense of 'assume', instead of 'presume'. This means, 

62205  400 
a goal like "\<And>x. A x \<Longrightarrow> B x \<Longrightarrow> C x" can be solved completely as 
401 
follows: 

60595  402 

403 
show "\<And>x. A x \<Longrightarrow> B x \<Longrightarrow> C x" 

404 

405 
or: 

406 

407 
show "C x" if "A x" "B x" for x 

408 

409 
Rare INCOMPATIBILITY, the old behaviour may be recovered as follows: 

410 

411 
show "C x" when "A x" "B x" for x 

412 

60459  413 
* New command 'consider' states rules for generalized elimination and 
414 
case splitting. This is like a toplevel statement "theorem obtains" used 

415 
within a proof body; or like a multibranch 'obtain' without activation 

416 
of the local context elements yet. 

417 

60455  418 
* Proof method "cases" allows to specify the rule as first entry of 
419 
chained facts. This is particularly useful with 'consider': 

420 

421 
consider (a) A  (b) B  (c) C <proof> 

422 
then have something 

423 
proof cases 

424 
case a 

425 
then show ?thesis <proof> 

426 
next 

427 
case b 

428 
then show ?thesis <proof> 

429 
next 

430 
case c 

431 
then show ?thesis <proof> 

432 
qed 

433 

60565  434 
* Command 'case' allows fact name and attribute specification like this: 
435 

436 
case a: (c xs) 

437 
case a [attributes]: (c xs) 

438 

439 
Facts that are introduced by invoking the case context are uniformly 

440 
qualified by "a"; the same name is used for the cumulative fact. The old 

441 
form "case (c xs) [attributes]" is no longer supported. Rare 

442 
INCOMPATIBILITY, need to adapt uses of case facts in exotic situations, 

443 
and always put attributes in front.

* Nesting of Isar goal structure has been clarified: the context after

453 
relevant for 'using', 'including', 'supply':

60631  472

473

* The undocumented feature of implicit cases goal1, goal2, goal3, etc. 
60617  505 
is marked as legacy, and will be removed eventually. The proof method 
506 
"goals" achieves a similar effect within regular Isar; often it can be 

507

'abbreviation' is also kept for morphims that only change the involved

parameters, and only 'notation' is suppressed. This can be of great help 
531 
when working with complex locale hierarchies, because proof states are

* The 'typedef' command has been upgraded from a partially checked 
574 
"axiomatization", to a full definitional specification that takes the 

575 
global collection of overloaded constant / type definitions into 

576 
account. Type definitions with open dependencies on overloaded 

577 
definitions need to be specified as "typedef (overloaded)". This 

578 
provides extra robustness in theory construction. Rare INCOMPATIBILITY. 

579 

580 
* Qualification of various formal entities in the libraries is done more 

581 
uniformly via "context begin qualified definition ... end" instead of 

582 
oldstyle "hide_const (open) ...". Consequently, both the defined 

583 
constant and its defining fact become qualified, e.g. Option.is_none and 

584 
Option.is_none_def. Occasional INCOMPATIBILITY in applications. 

585 

586 
* Some old and rarely used ASCII replacement syntax has been removed. 

587 
INCOMPATIBILITY, standard syntax with symbols should be used instead. 

588 
The subsequent commands help to reproduce the old forms, e.g. to 

589 
simplify porting old theories: 

590

614 
notation NSLIM ("((_)/  (_)/ NS> (_))" [60, 0, 60] 60) 

615 

616 
* The alternative notation "\<Colon>" for type and sort constraints has been 

617 
removed: in LaTeX document output it looks the same as "::". 

618 
INCOMPATIBILITY, use plain "::" instead. 

619 

620 
* Commands 'inductive' and 'inductive_set' work better when names for 

621 
intro rules are omitted: the "cases" and "induct" rules no longer 

622 
declare empty case_names, but no case_names at all. This allows to use 

623 
numbered cases in proofs, without requiring method "goal_cases". 

624 

625 
* Inductive definitions ('inductive', 'coinductive', etc.) expose 

626 
lowlevel facts of the internal construction only if the option 

62093  627 
"inductive_internals" is enabled. This refers to the internal predicate 
62017  628 
definition and its monotonicity result. Rare INCOMPATIBILITY. 
629 

630 
* Recursive function definitions ('fun', 'function', 'partial_function') 

631 
expose lowlevel facts of the internal construction only if the option 

62205  632 
"function_internals" is enabled. Its internal inductive definition is 
633 
also subject to "inductive_internals". Rare INCOMPATIBILITY. 

62093  634 

635 
* BNF datatypes ('datatype', 'codatatype', etc.) expose lowlevel facts 

636 
of the internal construction only if the option "bnf_internals" is 

637 
enabled. This supersedes the former option "bnf_note_all". Rare 

638 
INCOMPATIBILITY. 

62017  639 

640 
* Combinator to represent case distinction on products is named 

641 
"case_prod", uniformly, discontinuing any input aliasses. Very popular 

642 
theorem aliasses have been retained.

* The coercions to type 'real' have been reorganised. The function 

690 
'real' is no longer overloaded, but has type 'nat => real' and 

691 
abbreviates of_nat for that type. Also 'real_of_int :: int => real' 

692 
abbreviates of_int for that type. Other overloaded instances of 'real' 

693 
have been replaced by 'real_of_ereal' and 'real_of_float'.

1031 
together with an attribute to maintain the content incrementally. This 

1032 
supersedes functor Named_Thms in Isabelle/ML, but with a subtle change

*** Document preparation *** 
1094 

1095 
* Document markup commands 'chapter', 'section', 'subsection', 

1096 
'subsubsection', 'text', 'txt', 'text_raw' work uniformly in any 

1097 
context, even before the initial 'theory' command. Obsolete proof 

1098 
commands 'sect', 'subsect', 'subsubsect', 'txt_raw' have been 

1099 
discontinued, use 'section', 'subsection', 'subsubsection', 'text_raw' 

1100 
instead. The old 'header' command is still retained for some time, but 

1101 
should be replaced by 'chapter', 'section' etc. (using "isabelle 

1102 
update_header"). Minor INCOMPATIBILITY. 

1103 

60009  1104 
* Official support for "tt" style variants, via \isatt{...} or 
1105 
\begin{isabellett}...\end{isabellett}. The somewhat fragile \verb or 

1106 
verbatim environment of LaTeX is no longer used. This allows @{ML} etc. 

1107 
as argument to other macros (such as footnotes). 

1108 

1109 
* Document antiquotation @{verbatim} prints ASCII text literally in "tt" 

1110 
style. 

1111 

1112 
* Discontinued obsolete option "document_graph": session_graph.pdf is 

1113 
produced unconditionally for HTML browser_info and PDFLaTeX document. 

1114 

59951  1115 
* Diagnostic commands and document markup commands within a proof do not 
1116 
affect the command tag for output. Thus commands like 'thm' are subject 

1117 
to proof document structure, and no longer "stick out" accidentally. 

1118 
Commands 'text' and 'txt' merely differ in the LaTeX style, not their 

1119 
tags. Potential INCOMPATIBILITY in exotic situations. 

1120 

1121 
* System option "pretty_margin" is superseded by "thy_output_margin", 

1122 
which is also accessible via document antiquotation option "margin". 

1123 
Only the margin for document output may be changed, but not the global 

1124 
pretty printing: that is 76 for plain console output, and adapted 

1125 
dynamically in GUI frontends. Implementations of document 

1126 
antiquotations need to observe the margin explicitly according to 

1127 
Thy_Output.string_of_margin. Minor INCOMPATIBILITY.

1193 
INCOMPATIBILITY.

 The rule "set_cases" is now registered with the "[cases set]" 

57990  1195 
attribute. This can influence the behavior of the "cases" proof 
1196 
method when more than one case rule is applicable (e.g., an 

1197 
assumption is of the form "w : set ws" and the method "cases w" 

1198 
is invoked). The solution is to specify the case rule explicitly 

1199

'src/HOL/Library/Old_SMT.thy'. It is provided for compatibility, 
1255 
until applications have been ported to use the new 'smt' method. For 

1256 
the method to work, an older version of Z3 (e.g. Z3 3.2 or 4.0) must 

1257 
be installed, and the environment variable "OLD_Z3_SOLVER" must 

1258 
point to it. 

58062  1259

1265 
method, especially runtime statistics of Z3 proof reconstruction. 

58060  1266 

60261  1267 
* Lifting: command 'lift_definition' allows to execute lifted constants 
1268 
that have as a return type a datatype containing a subtype. This 

1269 
overcomes longtime limitations in the area of code generation and 

1270 
lifting, and avoids tedious workarounds. 

60258  1271 

60009  1272

1273 
(again), where the previous strategy (NBE after ML) serves as default.

1276 
* Add NO_MATCHsimproc, allows to check for syntactic nonequality. 

1277 

1278 
* field_simps: Use NO_MATCHsimproc for distribution rules, to avoid 

1279 
nontermination in case of distributing a division. With this change 

1280 
field_simps is in some cases slightly less powerful, if it fails try to 

1281 
add algebra_simps, or use divide_simps. Minor INCOMPATIBILITY. 

1282 

1283

1284 
algebraic semiring_no_zero_divisors. INCOMPATIBILITY.

1308 
* The factorial function, "fact", now has type "nat => 'a" (of a sort 

1309 
that admits numeric types including nat, int, real and complex. 

1310 
INCOMPATIBILITY: an expression such as "fact 3 = 6" may require a type 

1311 
constraint, and the combination "real (fact k)" is likely to be 

1312 
unsatisfactory. If a type conversion is still necessary, then use 

1313 
"of_nat (fact k)" or "real_of_nat (fact k)". 

1314 

1315 
* Removed functions "natfloor" and "natceiling", use "nat o floor" and 

1316 
"nat o ceiling" instead. A few of the lemmas have been retained and 

1317 
adapted: in their names "natfloor"/"natceiling" has been replaced by 

1318 
"nat_floor"/"nat_ceiling".

1330 
mult_less_imp_less_left ~> mult_left_less_imp_less 

1331

1332 

1333

1334 
double_add_less_zero_iff_single_add_less_zero (simp by default anyway). 

1335
