44760  9 
* Improved Isabelle/jEdit Prover IDE (PIDE), which can be invoked as 
44968  10 
"isabelle jedit" or "ISABELLE_HOME/Isabelle" on the command line. 
44760  11 

44777  12 
 Management of multiple theory files directly from the editor 
44760  13 
buffer store  bypassing the filesystem (no requirement to save 
14 
files for checking). 

15 

44777  16 
 Markup of formal entities within the text buffer, with semantic 
44760  17 
highlighting, tooltips and hyperlinks to jump to defining source 
18 
positions. 

19 

44777  20 
 Improved text rendering, with sub/superscripts in the source 
21 
buffer (including support for copy/paste wrt. output panel, HTML 

22 
theory output and other nonIsabelle text boxes). 

23 

24 
 Refined scheduling of proof checking and printing of results, 

44760  25 
based on interactive editor view. (Note: jEdit folding and 
26 
narrowing allows to restrict buffer perspectives explicitly.) 

27 

44777  28 
 Reduced CPU performance requirements, usable on machines with few 
44760  29 
cores. 
30 

44777  31 
 Reduced memory requirements due to pruning of unused document 
44760  32 
versions (garbage collection). 
33 

34 
See also ~~/src/Tools/jEdit/README.html for further information, 

35 
including some remaining limitations. 

36 

44800  37 
* Theory loader: source files are exclusively located via the master 
38 
directory of each theory node (where the .thy file itself resides). 

39 
The global load path (such as src/HOL/Library) has been discontinued. 

40 
Note that the path element ~~ may be used to reference theories in the 

41 
Isabelle home folder  for instance, "~~/src/HOL/Library/FuncSet". 

42 
INCOMPATIBILITY.

* Literal facts `prop` may contain dummy patterns, e.g. `_ = _`. Note 
64 
that the result needs to be unique, which means fact specifications 

65 
may have to be refined after enriching a proof context. 

66 

44800  67 
* Attribute "case_names" has been refined: the assumptions in each case 
68 
can be named now by following the case name with [name1 name2 ...]. 

69 

44968  70 
* Isabelle/Isar reference manual has been updated and extended: 
71 
 "Synopsis" provides a catalog of main Isar language concepts. 

72 
 Formal references in syntax diagrams, via @{rail} antiquotation. 

73 
 Updated material from classic "ref" manual, notably about 

74 
"Classical Reasoner".

44967  230 
* Theory Complex_Main: The definition of infinite series was 
231 
generalized. Now it is defined on the type class {topological_space, 

232 
comm_monoid_add}. Hence it is useable also for extended real numbers. 

42484  233 

44908  234 
* Theory Complex_Main: The complex exponential function "expi" is now 
235 
a typeconstrained abbreviation for "exp :: complex => complex"; thus 

236 
several polymorphic lemmas about "exp" are now applicable to "expi". 

237 

44968  238 
* Code generation: 
239 

240 
 Theory Library/Code_Char_ord provides native ordering of 

241 
characters in the target language. 

242 

243 
 Commands code_module and code_library are legacy, use export_code 

244 
instead. 

245 

246 
 Method "evaluation" is legacy, use method "eval" instead. 

247 

248 
 Legacy evaluator "SML" is deactivated by default. May be 

249 
reactivated by the following theory command: 

250 

251 
setup {* Value.add_evaluator ("SML", Codegen.eval_term) *} 

252 

253 
* Declare ext [intro] by default. Rare INCOMPATIBILITY. 

254 

255 
* Method "fastsimp" has been renamed to "fastforce", but "fastsimp" is 

256 
still available as a legacy feature for some time. 

257 

258 
* Nitpick: 

259 
 Added "need" and "total_consts" options. 

260 
 Reintroduced "show_skolems" option by popular demand. 

261 
 Renamed attribute: nitpick_def ~> nitpick_unfold. 

262 
INCOMPATIBILITY. 

263 

264 
* Sledgehammer: 

265 
 Use quasisound (and efficient) translations by default. 

266 
 Added support for the following provers: EToFoF, LEOII, 

267 
Satallax, SNARK, Waldmeister, and Z3 with TPTP syntax. 

268 
 Automatically preplay and minimize proofs before showing them if 

269 
this can be done within reasonable time. 

270 
 sledgehammer available_provers ~> sledgehammer supported_provers. 

271 
INCOMPATIBILITY. 

272 
 Added "preplay_timeout", "slicing", "type_enc", "sound", 

273 
"max_mono_iters", and "max_new_mono_instances" options. 

274 
 Removed "explicit_apply" and "full_types" options as well as "Full 

275 
Types" Proof General menu item. INCOMPATIBILITY. 

276 

277 
* Metis: 

278 
 Removed "metisF"  use "metis" instead. INCOMPATIBILITY. 

279 
 Obsoleted "metisFT"  use "metis (full_types)" instead. 

280 
INCOMPATIBILITY. 

281 

282 
* Command 'try': 

283 
 Renamed 'try_methods' and added "simp:", "intro:", "dest:", and 

284 
"elim:" options. INCOMPATIBILITY. 

285 
 Introduced 'try' that not only runs 'try_methods' but also 

286 
'solve_direct', 'sledgehammer', 'quickcheck', and 'nitpick'. 

287 

288 
* Quickcheck: 

289 
 Added "eval" option to evaluate terms for the found counterexample 

290 
(currently only supported by the default (exhaustive) tester). 

291 
 Added postprocessing of terms to obtain readable counterexamples 

292 
(currently only supported by the default (exhaustive) tester). 

293 
 New counterexample generator quickcheck[narrowing] enables 

294 
narrowingbased testing. Requires the Glasgow Haskell compiler 

295 
with its installation location defined in the Isabelle settings 

296 
environment as ISABELLE_GHC. 

297 
 Removed quickcheck tester "SML" based on the SML code generator 

298 
(formly in HOL/Library). 

299 

300 
* Function package: discontinued option "tailrec". INCOMPATIBILITY, 

301 
use 'partial_function' instead. 

302 

303 
* Theory Library/Extended_Reals replaces now the positive extended 

304 
reals found in probability theory. This file is extended by 

305 
Multivariate_Analysis/Extended_Real_Limits. 

306 

307 
* Old 'recdef' package has been moved to theory Library/Old_Recdef, 

308 
from where it must be imported explicitly. INCOMPATIBILITY. 

309 

310 
* Theory Library/Wfrec: wellfounded recursion combinator "wfrec" has 

311 
been moved here. INCOMPATIBILITY. 

312 

313 
* Theory Library/Saturated provides type of numbers with saturated 

314 
arithmetic. 

315 

316 
* Theory Library/Product_Lattice defines a pointwise ordering for the 

317 
product type 'a * 'b, and provides instance proofs for various order 

318 
and lattice type classes. 

319 

320 
* Theory Library/Countable now provides the "countable_datatype" proof 

321 
method for proving "countable" class instances for datatypes. 

322 

323 
* Theory Library/Cset_Monad allows do notation for computable sets 

324 
(cset) via the generic monad adhoc overloading facility. 

325 

326 
* Library: Theories of common data structures are split into theories 

327 
for implementation, an invariantensuring type, and connection to an 

328 
abstract type. INCOMPATIBILITY. 

329 

330 
 RBT is split into RBT and RBT_Mapping. 

331 
 AssocList is split and renamed into AList and AList_Mapping. 

332 
 DList is split into DList_Impl, DList, and DList_Cset. 

333 
 Cset is split into Cset and List_Cset. 

334 

335 
* Theory Library/Nat_Infinity has been renamed to 

336 
Library/Extended_Nat, with name changes of the following types and 

337 
constants: 

338 

339 
type inat ~> type enat 

340 
Fin ~> enat 

341 
Infty ~> infinity (overloaded) 

342 
iSuc ~> eSuc 

343 
the_Fin ~> the_enat 

344 

345 
Every theorem name containing "inat", "Fin", "Infty", or "iSuc" has 

346 
been renamed accordingly. INCOMPATIBILITY. 

347 

348 
* Session Multivariate_Analysis: The euclidean_space type class now 

349 
fixes a constant "Basis :: 'a set" consisting of the standard 

350 
orthonormal basis for the type. Users now have the option of 

351 
quantifying over this set instead of using the "basis" function, e.g. 

352 
"ALL x:Basis. P x" vs "ALL i<DIM('a). P (basis i)". 

353 

354 
* Session Multivariate_Analysis: Type "('a, 'b) cart" has been renamed 

355 
to "('a, 'b) vec" (the syntax "'a ^ 'b" remains unaffected). Constants 

356 
"Cart_nth" and "Cart_lambda" have been respectively renamed to 

357 
"vec_nth" and "vec_lambda"; theorems mentioning those names have 

358 
changed to match. Definition theorems for overloaded constants now use 

359 
the standard "foo_vec_def" naming scheme. A few other theorems have 

360 
been renamed as follows (INCOMPATIBILITY): 

361 

362 
Cart_eq ~> vec_eq_iff 

363 
dist_nth_le_cart ~> dist_vec_nth_le 

364 
tendsto_vector ~> vec_tendstoI 

365 
Cauchy_vector ~> vec_CauchyI 

366 

367

735 
inductive predicates, similar to 'inductive_cases'. 

736 

41571  737

40948  760 
types. Warning: records are not covered by ancient SML code 
761 
generation any longer. INCOMPATIBILITY. In cases of need, a suitable 

762

766 
rep_datatype foo_ext ...

769 
'_type' suffix any longer (obsolete due to authentic syntax).

* Quickcheck now by default uses exhaustive testing instead of random 
41571  773 
testing. Random testing can be invoked by "quickcheck [random]", 
774 
exhaustive testing by "quickcheck [exhaustive]". 

41398  775 

776 
* Quickcheck instantiates polymorphic types with small finite 

777 
datatypes by default. This enables a simple execution mechanism to 

778 
handle quantifiers and function equality over the finite datatypes. 

779 

41571  780 
* Quickcheck random generator has been renamed from "code" to 
781 
"random". INCOMPATIBILITY. 

41398  782 

783 
* Quickcheck now has a configurable time limit which is set to 30 

784 
seconds by default. This can be changed by adding [timeout = n] to the 

785 
quickcheck command. The time limit for Auto Quickcheck is still set 

786

INCOMPATIBILITY. 

1005 

1006

* Theory Library/Multiset: renamed empty_idemp ~> empty_neutral. 

1015 
INCOMPATIBILITY. 

1016 

1017 
* Session Multivariate_Analysis: introduced a type class for euclidean 

1018 
space. Most theorems are now stated in terms of euclidean spaces 

1019 
instead of finite cartesian products. 

1020 

1021 
types 

1022 
real ^ 'n ~> 'a::real_vector 

1023 
~> 'a::euclidean_space

\<chi> x. _ ~> \<chi>\<chi> x. _ 

1030 
CARD('n) ~> DIM('a) 

1031 

1032 
Also note that the indices are now natural numbers and not from some 

1033 
finite type. Finite cartesian products of euclidean spaces, products 

1034 
of euclidean spaces the real and complex numbers are instantiated to 

1035 
be euclidean_spaces. INCOMPATIBILITY. 

1036 

1037 
* Session Probability: introduced pextreal as positive extended real 

1038 
numbers. Use pextreal as value for measures. Introduce the 

1039 
RadonNikodym derivative, product spaces and Fubini's theorem for 

1040 
arbitrary sigma finite measures. Introduces Lebesgue measure based on 

1041 
the integral in Multivariate Analysis. INCOMPATIBILITY. 

1042 

1043 
* Session Imperative_HOL: revamped, corrected dozens of inadequacies. 

1044 
INCOMPATIBILITY. 

1045

1047 
prove verification conditions generated by the SPARK Ada program 

1048 
verifier. See also src/HOL/SPARK and src/HOL/SPARK/Examples.

* The domain package now runs in definitional mode by default: The 

41571  1066 
former command 'new_domain' is now called 'domain'. To use the domain 
40621  1067 
package in its original axiomatic mode, use 'domain (unsafe)'. 
1068 
INCOMPATIBILITY. 

1069 

41571  1070 
* The new class "domain" is now the default sort. Class "predomain" 
1071 
is an unpointed version of "domain". Theories can be updated by 

1072

1077 

41571  1078 
* The old type class "rep" has been superseded by class "domain". 
40621  1079 
Accordingly, users of the definitional package must remove any 
41571  1080 
"default_sort rep" declarations. INCOMPATIBILITY. 
40621  1081 

41401  1082 
* The domain package (definitional mode) now supports unpointed 
1083 
predomain argument types, as long as they are marked 'lazy'. (Strict 

41571  1084 
arguments must be in class "domain".) For example, the following 
41401  1085 
domain definition now works: 
1086 

1087 
domain natlist = nil  cons (lazy "nat discr") (lazy "natlist") 

1088 

1089 
* Theory HOLCF/Library/HOL_Cpo provides cpo and predomain class 

41571  1090 
instances for types from main HOL: bool, nat, int, char, 'a + 'b, 
1091 
'a option, and 'a list. Additionally, it configures fixrec and the 

1092 
domain package to work with these types. For example: 

41401  1093 

1094 
fixrec isInl :: "('a + 'b) u > tr" 

1095 
where "isInl$(up$(Inl x)) = TT"  "isInl$(up$(Inr y)) = FF" 

1096 

1097 
domain V = VFun (lazy "V > V")  VCon (lazy "nat") (lazy "V list") 

1098 

41571  1099 
* The "(permissive)" option of fixrec has been replaced with a 
1100 
perequation "(unchecked)" option. See 

1101 
src/HOL/HOLCF/Tutorial/Fixrec_ex.thy for examples. INCOMPATIBILITY. 

1102

* The "bifinite" class no longer fixes a constant "approx"; the class 

1104

* The monadic bind operator on each powerdomain has new binder syntax 

41571  1121

1122 
"upper_bind\<cdot>xs\<cdot>(\<Lambda> x. t)".

 Definitions of "bisim" constants no longer mention definedness. 

1157 
 With mutual recursion, "bisim" predicate is now curried.

*** General *** 
1316 

35436  1317 
* Authentic syntax for *all* logical entities (type classes, type 
1318 
constructors, term constants): provides simple and robust 

1319 
correspondence between formal entities and concrete syntax. Within 

1320 
the parse tree / AST representations, "constants" are decorated by 

1321 
their category (class, type, const) and spelled out explicitly with 

1322 
their full internal name. 

1323 

1324 
Substantial INCOMPATIBILITY concerning lowlevel syntax declarations 

1325 
and translations (translation rules and translation functions in ML). 

1326 
Some hints on upgrading: 

35260  1327 

1328 
 Many existing uses of 'syntax' and 'translations' can be replaced 

35436  1329 
by more modern 'type_notation', 'notation' and 'abbreviation', 
1330 
which are independent of this issue. 

35260  1331 

1332 
 'translations' require markup within the AST; the term syntax 

1333 
provides the following special forms: 

1334 

1335 
CONST c  produces syntax version of constant c from context 

35261  1336 
XCONST c  literally c, checked as constant from context 
1337 
c  literally c, if declared by 'syntax' 

1338 

1339 
Plain identifiers are treated as AST variables  occasionally the 

1340 
system indicates accidental variables via the error "rhs contains 

1341 
extra variables". 

35260  1342 

35436  1343 
Type classes and type constructors are marked according to their 
1344 
concrete syntax. Some old translations rules need to be written 

1345 
for the "type" category, using type constructor application 

1346 
instead of pseudoterm application of the default category 

1347 
"logic". 

1348 

35260  1349 
 'parse_translation' etc. in ML may use the following 
1350 
antiquotations: 

1351 

35436  1352 
@{class_syntax c}  type class c within parse tree / AST 
1353 
@{term_syntax c}  type constructor c within parse tree / AST 

35260  1354 
@{const_syntax c}  ML version of "CONST c" above 
1355 
@{syntax_const c}  literally c (checked wrt. 'syntax' declarations) 

1356 

35436  1357 
 Literal types within 'typed_print_translations', i.e. those *not* 
1358 
represented as pseudoterms are represented verbatim. Use @{class 

1359 
c} or @{type_name c} here instead of the above syntax 

1360 
antiquotations. 

1361 

35260  1362 
Note that old nonauthentic syntax was based on unqualified base 
35436  1363 
names, so all of the above "constant" names would coincide. Recall 
1364 
that 'print_syntax' and ML_command "set Syntax.trace_ast" help to 

1365 
diagnose syntax problems.
