62216  22 

23 

62327  24 
*** HOL *** 
25 

62522  26 
* New abbreviations for negated existence (but not bounded existence): 
27 

28 
\<nexists>x. P x \<equiv> \<not> (\<exists>x. P x) 

29 
\<nexists>!x. P x \<equiv> \<not> (\<exists>!x. P x) 

30 

62521  31 
* The print mode "HOL" for ASCII syntax of binders "!", "?", "?!", "@" 
32 
has been removed for output. It is retained for input only, until it is 

33 
eliminated altogether. 

34 

62327  35 
* (Co)datatype package: 
62332  36 
 the predicator :: ('a => bool) => 'a F => bool is now a firstclass 
37 
citizen in bounded natural functors 

62327  38 
 "primrec" now allows nested calls through the predicator in addition 
39 
to the map function. 

62332  40 
 "bnf" automatically discharges reflexive proof obligations 
41 
"bnf" outputs a slightly modified proof obligation expressing rel in 

42 
terms of map and set 

43 
(not giving a specification for rel makes this one reflexive) 

44 
"bnf" outputs a new proof obligation expressing pred in terms of set 

45 
(not giving a specification for pred makes this one reflexive) 

46 
INCOMPATIBILITY: manual "bnf" declarations may need adjustment 

62335  47 
 Renamed lemmas: 
48 
rel_prod_apply ~> rel_prod_inject 

49 
pred_prod_apply ~> pred_prod_inject 

50 
INCOMPATIBILITY. 

62327  51 

62407  52 
* Renamed split_if > if_split and split_if_asm > if_split_asm to 
53 
resemble the f.split naming convention, INCOMPATIBILITY.

311 
'SML_file_no_debug' control compilation of sources with or without 

312

313

320

323 
avoid GUI overcrowding. INCOMPATIBILITY, use the State panel instead or

61215  325

* The text overview column (status of errors, warnings etc.) is updated 
327 
asynchronously, leading to much better editor reactivity. Moreover, the 

328 
full document node content is taken into account. The width of the 

329 
column is scaled according to the main text area font, for improved 

330 
visibility. 

331 

332 
* The main text area no longer changes its color hue in outdated 

333 
situations. The text overview column takes over the role to indicate 

334 
unfinished edits in the PIDE pipeline. This avoids flashing text display 

335 
due to adhoc updates by auxiliary GUI components, such as the State 

336 
panel.

456

The local assumptions are bound to the name "that". The result is 
458 
exported from context of the statement as usual. The above roughly 

60414  459 
corresponds to a raw proof block like this:

61733  471 
* Assumptions ('assume', 'presume') allow structured rule statements 
472 
using 'if' and 'for', similar to 'have' etc. above. For example: 

61658  473 

474 
assume result: "C x y" 

475 
if "A x" and "B y" 

476 
for x :: 'a and y :: 'a 

477 

478 
This assumes "\<And>x y::'a. A x \<Longrightarrow> B y \<Longrightarrow> C x y" and produces a general 

479 
result as usual: "A ?x \<Longrightarrow> B ?y \<Longrightarrow> C ?x ?y". 

480 

481 
Vacuous quantification in assumptions is omitted, i.e. a forcontext 

482 
only effects propositions according to actual use of variables. For 

483 
example: 

484 

485 
assume "A x" and "B y" for x and y 

486 

487 
is equivalent to: 

488 

489 
assume "\<And>x. A x" and "\<And>y. B y" 

490 

60595  491 
* The meaning of 'show' with Pure rule statements has changed: premises 
492 
are treated in the sense of 'assume', instead of 'presume'. This means, 

62205  493 
a goal like "\<And>x. A x \<Longrightarrow> B x \<Longrightarrow> C x" can be solved completely as 
494 
follows: 

60595  495 

496 
show "\<And>x. A x \<Longrightarrow> B x \<Longrightarrow> C x" 

497 

498 
or: 

499 

500 
show "C x" if "A x" "B x" for x 

501 

502 
Rare INCOMPATIBILITY, the old behaviour may be recovered as follows: 

503 

504 
show "C x" when "A x" "B x" for x 

505 

60459  506 
* New command 'consider' states rules for generalized elimination and 
507 
case splitting. This is like a toplevel statement "theorem obtains" used 

508 
within a proof body; or like a multibranch 'obtain' without activation 

509 
of the local context elements yet. 

510 

60455  511 
* Proof method "cases" allows to specify the rule as first entry of 
512 
chained facts. This is particularly useful with 'consider': 

513 

514 
consider (a) A  (b) B  (c) C <proof> 

515 
then have something 

516 
proof cases 

517 
case a 

518 
then show ?thesis <proof> 

519

520 
case b 

521 
then show ?thesis <proof> 

522

523 
case c 

524 
then show ?thesis <proof> 

525

526 

60565  527 
* Command 'case' allows fact name and attribute specification like this: 
528 

529 
case a: (c xs) 

530 
case a [attributes]: (c xs) 

531 

532 
Facts that are introduced by invoking the case context are uniformly 

533 
qualified by "a"; the same name is used for the cumulative fact. The old 

534 
form "case (c xs) [attributes]" is no longer supported. Rare 

535 
INCOMPATIBILITY, need to adapt uses of case facts in exotic situations, 

536 
and always put attributes in front.

* Nesting of Isar goal structure has been clarified: the context after 
544 
the initial backwards refinement is retained for the whole proof, within 

545 
all its context sections (as indicated via 'next'). This is e.g. 

546 
relevant for 'using', 'including', 'supply':

559 
* Improved typeinference for theorem statement 'obtains': separate 

560

561 

562 
* Term abbreviations via 'is' patterns also work for schematic 

563 
statements: result is abstracted over unknowns. 

564 

60631  565 
* Command 'subgoal' allows to impose some structure on backward 
566 
refinements, to avoid proof scripts degenerating into long of 'apply' 

567

manual.

783 
'real' is no longer overloaded, but has type 'nat => real' and 

784 
abbreviates of_nat for that type. Also 'real_of_int :: int => real' 

785 
abbreviates of_int for that type. Other overloaded instances of 'real' 

786

* The following combinators for lowlevel profiling of the ML runtime 
983 
system are available: 

984 

985 
profile_time (*CPU time*) 

986 
profile_time_thread (*CPU time on this thread*)

* Antiquotation @{method NAME} inlines the (checked) name of the given 
992 
Isar proof method. 

993 

61922  994 
* Pretty printing of Poly/ML compiler output in Isabelle has been 
995 
improved: proper treatment of break offsets and blocks with consistent 

996 
breaks. 

997 

61268  998 
* The auxiliary module Pure/display.ML has been eliminated. Its 
999 
elementary thm print operations are now in Pure/more_thm.ML and thus 

1000 
called Thm.pretty_thm, Thm.string_of_thm etc. INCOMPATIBILITY.

* Simproc programming interfaces have been simplified: 
1003 
Simplifier.make_simproc and Simplifier.define_simproc supersede various

1005 
term patterns for the lefthand sides are specified with implicitly 

1006

1011 
Thm.instantiate' (*version with positional arguments*) 

1012 

1013 
Drule.infer_instantiate (*instantiation with type inference*) 

1014 
Drule.infer_instantiate' (*version with positional arguments*) 

1015 

1016 
The LHS only requires variable specifications, instead of full terms. 

1017 
Old cterm_instantiate is superseded by infer_instantiate. 

1018 
INCOMPATIBILITY, need to readjust some ML names and types accordingly. 

1019 

60793  1020 
* Old tactic shorthands atac, rtac, etac, dtac, ftac have been

* Command 'experiment' opens an anonymous locale context with private

1118 

59951  1119 
* Command 'notepad' requires proper nesting of begin/end and its proof 
1120 
structure in the body: 'oops' is no longer supported here. Minor 

1121 
INCOMPATIBILITY, use 'sorry' instead. 

1122 

1123 
* Command 'named_theorems' declares a dynamic fact within the context, 

1124 
together with an attribute to maintain the content incrementally. This 

1125 
supersedes functor Named_Thms in Isabelle/ML, but with a subtle change 

1126 
of semantics due to external visual order vs. internal reverse order.

1128 
* 'find_theorems': search patterns which are abstractions are 

1129 
schematically expanded before search. Search results match the naive

*** Document preparation *** 
1187 

1188 
* Document markup commands 'chapter', 'section', 'subsection', 

1189 
'subsubsection', 'text', 'txt', 'text_raw' work uniformly in any 

1190 
context, even before the initial 'theory' command. Obsolete proof 

1191 
commands 'sect', 'subsect', 'subsubsect', 'txt_raw' have been 

1192 
discontinued, use 'section', 'subsection', 'subsubsection', 'text_raw' 

1193 
instead. The old 'header' command is still retained for some time, but 

1194 
should be replaced by 'chapter', 'section' etc. (using "isabelle 

1195 
update_header"). Minor INCOMPATIBILITY. 

1196 

60009  1197 
* Official support for "tt" style variants, via \isatt{...} or 
1198 
\begin{isabellett}...\end{isabellett}. The somewhat fragile \verb or 

1199 
verbatim environment of LaTeX is no longer used. This allows @{ML} etc. 

1200 
as argument to other macros (such as footnotes). 

1201 

1202 
* Document antiquotation @{verbatim} prints ASCII text literally in "tt" 

1203 
style. 

1204 

1205 
* Discontinued obsolete option "document_graph": session_graph.pdf is 

1206 
produced unconditionally for HTML browser_info and PDFLaTeX document. 

1207 

59951  1208 
* Diagnostic commands and document markup commands within a proof do not 
1209 
affect the command tag for output. Thus commands like 'thm' are subject 

1210 
to proof document structure, and no longer "stick out" accidentally. 

1211 
Commands 'text' and 'txt' merely differ in the LaTeX style, not their 

1212 
tags. Potential INCOMPATIBILITY in exotic situations. 

1213 

1214 
* System option "pretty_margin" is superseded by "thy_output_margin", 

1215 
which is also accessible via document antiquotation option "margin". 

1216 
Only the margin for document output may be changed, but not the global 

1217 
pretty printing: that is 76 for plain console output, and adapted 

1218 
dynamically in GUI frontends. Implementations of document 

1219 
antiquotations need to observe the margin explicitly according to 

1220 
Thy_Output.string_of_margin. Minor INCOMPATIBILITY.

* Command and antiquotation "value" provide different evaluation slots 
1366 
(again), where the previous strategy (NBE after ML) serves as default. 

1367 
Minor INCOMPATIBILITY. 

1368 

1369 
* Add NO_MATCHsimproc, allows to check for syntactic nonequality. 

1370 

1371 
* field_simps: Use NO_MATCHsimproc for distribution rules, to avoid 

1372 
nontermination in case of distributing a division. With this change 

1373 
field_simps is in some cases slightly less powerful, if it fails try to 

1374 
add algebra_simps, or use divide_simps. Minor INCOMPATIBILITY. 

1375 

1376 
* Separate class no_zero_divisors has been given up in favour of fully 

1377 
algebraic semiring_no_zero_divisors. INCOMPATIBILITY. 

1378 

1379 
* Class linordered_semidom really requires no zero divisors. 

1380 
INCOMPATIBILITY. 

1381 

1382 
* Classes division_ring, field and linordered_field always demand 

1383 
"inverse 0 = 0". Given up separate classes division_ring_inverse_zero, 

1384 
field_inverse_zero and linordered_field_inverse_zero. INCOMPATIBILITY. 

1385 

1386 
* Classes cancel_ab_semigroup_add / cancel_monoid_add specify explicit 

1387 
additive inverse operation. INCOMPATIBILITY.

* Complex powers and square roots. The functions "ln" and "powr" are now 
60025  1390 
overloaded for types real and complex, and 0 powr y = 0 by definition. 
1391 
INCOMPATIBILITY: type constraints may be necessary.

* The functions "sin" and "cos" are now defined for any type of sort 
1394 
"{real_normed_algebra_1,banach}" type, so in particular on "real" and 

1395 
"complex" uniformly. Minor INCOMPATIBILITY: type constraints may be

* New library of properties of the complex transcendental functions sin, 

1399 
cos, tan, exp, Ln, Arctan, Arcsin, Arccos. Ported from HOL Light.

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

1402 
that admits numeric types including nat, int, real and complex.
