17865  29 
*** Document preparation *** 
30 

17869  31 
* Added antiquotations @{ML_type text} and @{ML_struct text} which 
32 
check the given source text as ML type/structure, printing verbatim. 

17865  33 

34 

17779  35 
*** Pure *** 
36 

17865  37 
* Isar: improper proof element 'guess' is like 'obtain', but derives 
38 
the obtained context from the course of reasoning! For example: 

39 

40 
assume "EX x y. A x & B y"  "any previous fact" 

41 
then guess x and y by clarify 

42 

43 
This technique is potentially adventurous, depending on the facts and 

44 
proof tools being involved here. 

45 

18020  46 
* Isar: known facts from the proof context may be specified as literal 
47 
propositions, using ASCII backquote syntax. This works wherever 

48 
named facts used to be allowed so far, in proof commands, proof 

49 
methods, attributes etc. Literal facts are retrieved from the context 

50 
according to unification of type and term parameters. For example, 

51 
provided that "A" and "A ==> B" and "!!x. P x ==> Q x" are known 

52 
theorems in the current context, then these are valid literal facts: 

53 
`A` and `A ==> B` and `!!x. P x ==> Q x" as well as `P a ==> Q a` etc. 

54 

55 
There is also a proof method "fact" which does the same composition 

18044  56 
for explicit goal states, e.g. the following proof texts coincide with 
57 
certain special cases of literal facts: 

18020  58 

59 
have "A" by fact == note `A` 

60 
have "A ==> B" by fact == note `A ==> B` 

61 
have "!!x. P x ==> Q x" by fact == note `!!x. P x ==> Q x` 

62 
have "P a ==> Q a" by fact == note `P a ==> Q a` 

63 

17779  64 
* Input syntax now supports dummy variable binding "%_. b", where the 
65 
body does not mention the bound variable. Note that dummy patterns 

66 
implicitly depend on their context of bounds, which makes "{_. _}" 

17780  67 
match any set comprehension as expected. Potential INCOMPATIBILITY  
68 
parse translations need to cope with syntactic constant "_idtdummy" in 

69 
the binding position. 

70 

71 
* Removed obsolete syntactic constant "_K" and its associated parse 

72 
translation. INCOMPATIBILITY  use dummy abstraction instead, for 

17779  73 
example "A > B" => "Pi A (%_. B)". 
74 

17865  75 

17806  76 
*** HOL *** 
77 

17996  78 
* Alternative iff syntax "A <> B" for equality on bool (with priority 
79 
25 like >); output depends on the "iff" print_mode, the default is 

80 
"A = B" (with priority 50). 

81 

17865  82 
* In the context of the assumption "~(s = t)" the Simplifier rewrites 
83 
"t = s" to False (by simproc "neq_simproc"). For backward 

84 
compatibility this can be disabled by ML "reset use_neq_simproc".

*** ML *** 
93 

17991  94 
* Library: new module Pure/General/rat.ML implementing rational numbers, 
95 
replacing the former functions in the Isabelle library. 

96 

18051  97 
* Library: indexed lists  some functions in the Isabelle library 
98 
treating lists over 'a as finite mappings from [0...n] to 'a 

99 
have been given more convenient names and signatures reminiscent 

100 
of similar functions for alists, tables, etc: 

101 

102 
val nth: 'a list > int > 'a 

103 
val nth_update: int * 'a > 'a list > 'a list 

104 
val nth_map: int > ('a > 'a) > 'a list > 'a list 

105 
val fold_index: (int * 'a > 'b > 'b) > 'a list > 'b > 'b 

106 

107 
Note that fold_index starts counting at index 0, not 1 like foldln used to. 

108 

18020  109 
* Pure: primitive rule lift_rule now takes goal cterm instead of an 
110 
actual goal state (thm). Use Thm.lift_rule (Thm.cgoal_of st i) to 

111 
achieve the old behaviour. 

112 

113 
* Pure: the "Goal" constant is now called "prop", supporting a 

114 
slightly more general idea of ``protecting'' metalevel rule 

115 
statements.

17878  123 
* Simplifier: the simpset of a running simplification process now 
124 
contains a proof context (cf. Simplifier.the_context), which is the 

125 
very context that the initial simpset has been retrieved from (by 

17890  126 
simpset_of/local_simpset_of). Consequently, all plugin components 
17878  127 
(solver, looper etc.) may depend on arbitrary proof data. 
128 

129 
* Simplifier.inherit_context inherits the proof context (plus the 

130 
local bounds) of the current simplification process; any simproc 

131 
etc. that calls the Simplifier recursively should do this! Removed 

132 
former Simplifier.inherit_bounds, which is already included here  

17890  133 
INCOMPATIBILITY. Tools based on lowlevel rewriting may even have to 
134 
specify an explicit context using Simplifier.context/theory_context. 

17878  135 

136 
* Simplifier/Classical Reasoner: more abstract interfaces 

137 
change_simpset/claset for modifying the simpset/claset reference of a 

138 
theory; raw versions simpset/claset_ref etc. have been discontinued  

139

274 
* Considerably improved version of 'constdefs' command. Now performs 

275 
automatic typeinference of declared constants; additional support for 

276 
local structure declarations (cf. locales and HOL records), see also 

277 
isarref manual. Potential INCOMPATIBILITY: need to observe strictly 

278 
sequential dependencies of definitions within a single 'constdefs' 

279 
section; moreover, the declared name needs to be an identifier. If 

280 
all fails, consider to fall back on 'consts' and 'defs' separately. 

281 

282 
* Improved indexed syntax and implicit structures. First of all, 

283 
indexed syntax provides a notational device for subscripted 

284 
application, using the new syntax \<^bsub>term\<^esub> for arbitrary 

285 
expressions. Secondly, in a local context with structure 

286 
declarations, number indexes \<^sub>n or the empty index (default 

287 
number 1) refer to a certain fixed variable implicitly; option 

288 
show_structs controls printing of implicit structures. Typical 

289 
applications of these concepts involve record types and locales. 

290 

291 
* New command 'no_syntax' removes grammar declarations (and 

292 
translations) resulting from the given syntax specification, which is 

293 
interpreted in the same manner as for the 'syntax' command. 

294 

295 
* 'Advanced' translation functions (parse_translation etc.) may depend 

296 
on the signature of the theory context being presently used for 

297 
parsing/printing, see also isarref manual. 

298

* Improved 'oracle' command provides a typesafe interface to turn an

314

315 

316 
* In schematic variable names, *any* symbol following \<^isub> or 

317 
\<^isup> is now treated as part of the base name. For example, the 

318 
following works without printing of awkward ".0" indexes: 

319

lemma "x\<^isub>1 = x\<^isub>2 ==> x\<^isub>2 = x\<^isub>1"

327 

328 
* Clear separation of logical types and nonterminals, where the latter 

329 
may only occur in 'syntax' specifications or type abbreviations. 

330 
Before that distinction was only partially implemented via type class 

331 
"logic" vs. "{}". Potential INCOMPATIBILITY in rare cases of improper 

332 
use of 'types'/'consts' instead of 'nonterminals'/'syntax'. Some very 

333 
exotic syntax specifications may require further adaption 

17691  334 
(e.g. Cube/Cube.thy). 
16234  335 

336 
* Removed obsolete type class "logic", use the top sort {} instead. 

337 
Note that nonlogical types should be declared as 'nonterminals' 

338 
rather than 'types'. INCOMPATIBILITY for new objectlogic 

339 
specifications. 

340 

17095  341

345

347 

348 
* Simplifier: simplification procedures may now take the current 

349 
simpset into account (cf. Simplifier.simproc(_i) / mk_simproc 

350 
interface), which is very useful for calling the Simplifier 

351 
recursively. Minor INCOMPATIBILITY: the 'prems' argument of simprocs 

352 
is gone  use prems_of_ss on the simpset instead. Moreover, the 

353 
lowlevel mk_simproc no longer applies Logic.varify internally, to 

354 
allow for use in a context of fixed variables. 

355 

356 
* thin_tac now works even if the assumption being deleted contains !!

* Method 'rules' has been renamed to 'iprover'. INCOMPATIBILITY. 
17590  361 

16234  362 
* Reorganized bootstrapping of the Pure theories; CPure is now derived 
363 
from Pure, which contains all common declarations already. Both 

364 
theories are defined via plain Isabelle/Isar .thy files. 

365 
INCOMPATIBILITY: elements of CPure (such as the CPure.intro / 

366 
CPure.elim / CPure.dest attributes) now appear in the Pure name space; 

367 
use isatool fixcpure to adapt your theory and ML sources.

*** Locales *** 

17095  392 

17385  393 
* New commands for the interpretation of locale expressions in 
394 
theories (1), locales (2) and proof contexts (3). These generate 

395 
proof obligations from the expression specification. After the 

396 
obligations have been discharged, theorems of the expression are added 

397 
to the theory, target locale or proof context. The synopsis of the 

398 
commands is a follows: 

399 

17095  400 
(1) interpretation expr inst 
401 
(2) interpretation target < expr 

402 
(3) interpret expr inst 

17385  403 

17095  404 
Interpretation in theories and proof contexts require a parameter 
405 
instantiation of terms from the current context. This is applied to 

17385  406 
specifications and theorems of the interpreted expression. 
407 
Interpretation in locales only permits parameter renaming through the 

408 
locale expression. Interpretation is smart in that interpretations 

409 
that are active already do not occur in proof obligations, neither are 

410 
instantiated theorems stored in duplicate. Use 'print_interps' to 

411 
inspect active interpretations of a particular locale. For details, 

17436  412 
see the Isar Reference manual. Examples can be found in 
413 
HOL/Finite_Set.thy and HOL/Algebra/UnivPoly.thy. 

16234  414 

415 
INCOMPATIBILITY: former 'instantiate' has been withdrawn, use 

416 
'interpret' instead. 

417 

17385  418 
* New context element 'constrains' for adding type constraints to 
419 
parameters. 

420 

421 
* Context expressions: renaming of parameters with syntax 

422 
redeclaration. 

17095  423 

424 
* Locale declaration: 'includes' disallowed. 

425 

16234  426 
* Proper static binding of attribute syntax  i.e. types / terms / 
427 
facts mentioned as arguments are always those of the locale definition 

428 
context, independently of the context of later invocations. Moreover, 

429 
locale operations (renaming and type / term instantiation) are applied 

430 
to attribute arguments as expected. 

431 

432 
INCOMPATIBILITY of the ML interface: always pass Attrib.src instead of 

433 
actual attributes; rare situations may require Attrib.attribute to 

434 
embed those attributes into Attrib.src that lack concrete syntax. 

435 
Attribute implementations need to cooperate properly with the static 

436 
binding mechanism. Basic parsers Args.XXX_typ/term/prop and 

437 
Attrib.XXX_thm etc. already do the right thing without further 

438 
intervention. Only unusual applications  such as "where" or "of" 

439 
(cf. src/Pure/Isar/attrib.ML), which process arguments depending both 

440 
on the context and the facts involved  may have to assign parsed 

441 
values to argument tokens explicitly. 

442 

443 
* Changed parameter management in theorem generation for long goal 

444 
statements with 'includes'. INCOMPATIBILITY: produces a different 

445 
theorem statement in rare situations. 

446 

17228  447 
* Locale inspection command 'print_locale' omits notes elements. Use 
448 
'print_locale!' to have them included in the output. 

449 

16234  450 

451 
*** Provers *** 

452

* Provers/hypsubst.ML: improved version of the subst method, for 

454 
singlestep rewriting: it now works in bound variable contexts. New is 

455 
'subst (asm)', for rewriting an assumption. INCOMPATIBILITY: may 

456 
rewrite a different subterm than the original subst method, which is 

457 
still available as 'simplesubst'. 

458 

459 
* Provers/quasi.ML: new transitivity reasoners for transitivity only 

460 
and quasi orders. 

461 

462 
* Provers/trancl.ML: new transitivity reasoner for transitive and 

463 
reflexivetransitive closure of relations. 

464 

465 
* Provers/blast.ML: new reference depth_limit to make blast's depth 

466 
limit (previously hardcoded with a value of 20) userdefinable. 

467 

468 
* Provers/simplifier.ML has been moved to Pure, where Simplifier.setup 

469

* "{x:A. P}" abbreviates "{x. x:A & P}", and similarly for "\<in>" 

491 
instead of ":". 

492 

493 
* theory SetInterval: changed the syntax for open intervals: 

494 

495 
Old New 

496 
{..n(} {..<n} 

497 
{)n..} {n<..} 

498 
{m..n(} {m..<n} 

499 
{)m..n} {m<..n} 

500 
{)m..n(} {m<..<n} 

501 

502 
The old syntax is still supported but will disappear in the next 

503 
release. For conversion use the following Emacs search and replace 

504 
patterns (these are not perfect but work quite well): 

15046  505 

506 
{)\([^\.]*\)\.\. > {\1<\.\.} 

507 
\.\.\([^(}]*\)(} > \.\.<\1}

513 
* Theory Finite_Set: changed the syntax for 'setsum', summation over 
16234  514 
finite sets: "setsum (%x. e) A", which used to be "\<Sum>x:A. e", is 
17371  515 
now either "SUM x:A. e" or "\<Sum>x \<in> A. e". The bound variable can 
17189  516 
be a tuple pattern. 
16234  517 

518 
Some new syntax forms are available: 

519 

520 
"\<Sum>x  P. e" for "setsum (%x. e) {x. P}" 

521 
"\<Sum>x = a..b. e" for "setsum (%x. e) {a..b}" 

522 
"\<Sum>x = a..<b. e" for "setsum (%x. e) {a..<b}" 

523 
"\<Sum>x < k. e" for "setsum (%x. e) {..<k}" 

524 

525 
The latter form "\<Sum>x < k. e" used to be based on a separate 

526 
function "Summation", which has been discontinued. 

527 

528 
* theory Finite_Set: in structured induction proofs, the insert case 

529 
is now 'case (insert x F)' instead of the old counterintuitive 'case 

530 
(insert F x)'. 

531 

532 
* The 'refute' command has been extended to support a much larger 

533 
fragment of HOL, including axiomatic type classes, constdefs and 

534 
typedefs, inductive datatypes and recursion. 

535 

17700  536 
* New tactics 'sat' and 'satx' to prove propositional tautologies. 
537 
Requires zChaff with proof generation to be installed. See 

538 
HOL/ex/SAT_Examples.thy for examples. 

17619  539 

16234  540 
* Datatype induction via method 'induct' now preserves the name of the 
541 
induction variable. For example, when proving P(xs::'a list) by 

542 
induction on xs, the induction step is now P(xs) ==> P(a#xs) rather 

543 
than P(list) ==> P(a#list) as previously. Potential INCOMPATIBILITY 

544 
in unstructured proof scripts. 

545 

546 
* Reworked implementation of records. Improved scalability for 

547 
records with many fields, avoiding performance problems for type 

548 
inference. Records are no longer composed of nested field types, but 

549 
of nested extension types. Therefore the record type only grows linear 

550 
in the number of extensions and not in the number of fields. The 

551 
toplevel (users) view on records is preserved. Potential 

552 
INCOMPATIBILITY only in strange cases, where the theory depends on the 

553 
old record representation. The type generated for a record is called 

554 
<record_name>_ext_type. 

555 

556 
Flag record_quick_and_dirty_sensitive can be enabled to skip the 

557 
proofs triggered by a record definition or a simproc (if 

558 
quick_and_dirty is enabled). Definitions of large records can take 

559 
quite long. 

560 

561 
New simproc record_upd_simproc for simplification of multiple record 

562 
updates enabled by default. Moreover, trivial updates are also 

563 
removed: r(x := x r) = r. INCOMPATIBILITY: old proofs break 

564 
occasionally, since simplification is more powerful by default.

16234  569 
* Simplifier: automatically reasons about transitivity chains 
570 
involving "trancl" (r^+) and "rtrancl" (r^*) by setting up tactics 

571 
provided by Provers/trancl.ML as additional solvers. INCOMPATIBILITY: 

572 
old proofs break occasionally as simplification may now solve more 

573 
goals than previously. 

574 

575 
* Simplifier: converts x <= y into x = y if assumption y <= x is 

576 
present. Works for all partial orders (class "order"), in particular 

577 
numbers and sets. For linear orders (e.g. numbers) it treats ~ x < y 

578 
just like y <= x. 

579 

580 
* Simplifier: new simproc for "let x = a in f x". If a is a free or 

581 
bound variable or a constant then the let is unfolded. Otherwise 

582 
first a is simplified to b, and then f b is simplified to g. If 

583 
possible we abstract b from g arriving at "let x = b in h x", 

584 
otherwise we unfold the let and arrive at g. The simproc can be 

585 
enabled/disabled by the reference use_let_simproc. Potential 

586 
INCOMPATIBILITY since simplification is more powerful by default. 

15776  587 

16563  588 
* Classical reasoning: the meson method now accepts theorems as arguments. 
589 

17595  590 
* Prover support: prerelease of the IsabelleATP linkup, which runs background 
591 
jobs to provide advice on the provability of subgoals.

* Theory OrderedGroup and Ring_and_Field: various additions and

595

* Numerics: 

1249 
 Numeric types (nat, int, and in HOLComplex rat, real, complex, etc.) are 

14731  1250 
now formalized using the Ring_and_Field theory mentioned above. 
14389  1251 
 INCOMPATIBILITY: simplification and arithmetic behaves somewhat differently 
1252 
than before, because now they are set up once in a generic manner. 

14731  1253 
 INCOMPATIBILITY: many typespecific arithmetic laws have gone.

1255 
exponentiation).

* Unions and Intersections: 
15119  1284 
The latex output syntax of UN and INT has been changed 
1285 
from "\Union x \in A. B" to "\Union_{x \in A} B" 

1286 
i.e. the index formulae has become a subscript. 

1287 
Similarly for "\Union x. B", and for \Inter instead of \Union. 

14380  1288 

14418  1289 
* Unions and Intersections over Intervals: 
14731  1290 
There is new short syntax "UN i<=n. A" for "UN i:{0..n}. A". There is 
1291 
also an xsymbol version with subscripts "\<Union>\<^bsub>i <= n\<^esub>. A" 

14418  1292 
like in normal math, and corresponding versions for < and for intersection. 
1293 

15677  1294 
* HOL/List: Ordering "lexico" is renamed "lenlex" and the standard 
1295 
lexicographic dictonary ordering has been added as "lexord". 

1296 

14401  1297 
* ML: the legacy theory structures Int and List have been removed. They had 
1298 
conflicted with ML Basis Library structures having the same names. 

14380  1299 

14464  1300 
* 'refute' command added to search for (finite) countermodels. Only works 
1301 
for a fragment of HOL. The installation of an external SAT solver is 

1302 
highly recommended. See "HOL/Refute.thy" for details. 

1303 

14602  1304 
* 'quickcheck' command: Allows to find counterexamples by evaluating 
1305 
formulae under an assignment of free variables to random values. 

1306 
In contrast to 'refute', it can deal with inductive datatypes, 

1307 
but cannot handle quantifiers. See "HOL/ex/Quickcheck_Examples.thy" 

1308 
for examples.

13618  1322 
* Provers/simplifier: 
1323 

13781  1324 
 Completely reimplemented method simp (ML: Asm_full_simp_tac): 
13618  1325 
Assumptions are now subject to complete mutual simplification, 
1326 
not just from left to right. The simplifier now preserves 

1327 
the order of assumptions. 

1328 

1329 
Potential INCOMPATIBILITY: 

1330 

13781  1331 
 simp sometimes diverges where the old version did 
1332 
not, e.g. invoking simp on the goal 

13618  1333 

1334 
[ P (f x); y = x; f x = f y ] ==> Q 

1335 

13781  1336 
now gives rise to the infinite reduction sequence 
1337 

1338 
P(f x) (f x = f y)> P(f y) (y = x)> P(f x) (f x = f y)> ... 

1339 

1340 
Using "simp (asm_lr)" (ML: Asm_lr_simp_tac) instead often solves this 

1341 
kind of problem. 

1342 

1343 
 Tactics combining classical reasoner and simplification (such as auto) 

1344 
are also affected by this change, because many of them rely on 

1345 
simp. They may sometimes diverge as well or yield a different numbers 

1346 
of subgoals. Try to use e.g. force, fastsimp, or safe instead of auto 

1347 
in case of problems. Sometimes subsequent calls to the classical 

1348 
reasoner will fail because a preceeding call to the simplifier too 

1349 
eagerly simplified the goal, e.g. deleted redundant premises. 

13618  1350 

1351 
 The simplifier trace now shows the names of the applied rewrite rules 

1352 

13829  1353 
 You can limit the number of recursive invocations of the simplifier 
1354 
during conditional rewriting (where the simplifie tries to solve the 

1355 
conditions before applying the rewrite rule): 

1356 
ML "simp_depth_limit := n" 

1357 
where n is an integer. Thus you can force termination where previously 

1358 
the simplifier would diverge.
