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".

84 
complete boolean algebras and complete linear orders. Lemmas 

85 
Inf_less_iff, less_Sup_iff, INF_less_iff, less_SUP_iff now reside in

44967  261 
* Theory Complex_Main: The definition of infinite series was 
262 
generalized. Now it is defined on the type class {topological_space, 

263 
comm_monoid_add}. Hence it is useable also for extended real numbers. 

42484  264 

44908  265 
* Theory Complex_Main: The complex exponential function "expi" is now 
266 
a typeconstrained abbreviation for "exp :: complex => complex"; thus 

267 
several polymorphic lemmas about "exp" are now applicable to "expi". 

268 

44968  269 
* Code generation: 
270 

271 
 Theory Library/Code_Char_ord provides native ordering of 

272 
characters in the target language. 

273 

274 
 Commands code_module and code_library are legacy, use export_code 

275 
instead. 

276 

277 
 Method "evaluation" is legacy, use method "eval" instead. 

278 

279 
 Legacy evaluator "SML" is deactivated by default. May be 

280 
reactivated by the following theory command: 

281 

282 
setup {* Value.add_evaluator ("SML", Codegen.eval_term) *} 

283 

284 
* Declare ext [intro] by default. Rare INCOMPATIBILITY. 

285 

45088  286 
* New proof method "induction" that gives induction hypotheses the 
287 
name "IH", thus distinguishing them from further hypotheses that come 

288 
from rule induction. The latter are still called "hyps". Method 

289 
"induction" is a thin wrapper around "induct" and follows the same 

290 
syntax. 

291 

44968  292 
* Method "fastsimp" has been renamed to "fastforce", but "fastsimp" is 
293 
still available as a legacy feature for some time. 

294 

295 
* Nitpick: 

296 
 Added "need" and "total_consts" options. 

297 
 Reintroduced "show_skolems" option by popular demand. 

298 
 Renamed attribute: nitpick_def ~> nitpick_unfold. 

299 
INCOMPATIBILITY. 

300 

301 
* Sledgehammer: 

302 
 Use quasisound (and efficient) translations by default. 

303 
 Added support for the following provers: EToFoF, LEOII, 

304 
Satallax, SNARK, Waldmeister, and Z3 with TPTP syntax. 

305 
 Automatically preplay and minimize proofs before showing them if 

306 
this can be done within reasonable time. 

307 
 sledgehammer available_provers ~> sledgehammer supported_provers. 

308 
INCOMPATIBILITY. 

309 
 Added "preplay_timeout", "slicing", "type_enc", "sound", 

310 
"max_mono_iters", and "max_new_mono_instances" options. 

311 
 Removed "explicit_apply" and "full_types" options as well as "Full 

312 
Types" Proof General menu item. INCOMPATIBILITY. 

313 

314 
* Metis: 

315 
 Removed "metisF"  use "metis" instead. INCOMPATIBILITY. 

316 
 Obsoleted "metisFT"  use "metis (full_types)" instead. 

317 
INCOMPATIBILITY. 

318 

319 
* Command 'try': 

320 
 Renamed 'try_methods' and added "simp:", "intro:", "dest:", and 

321 
"elim:" options. INCOMPATIBILITY. 

322 
 Introduced 'try' that not only runs 'try_methods' but also 

323 
'solve_direct', 'sledgehammer', 'quickcheck', and 'nitpick'. 

324 

325 
* Quickcheck: 

326 
 Added "eval" option to evaluate terms for the found counterexample 

327 
(currently only supported by the default (exhaustive) tester). 

328 
 Added postprocessing of terms to obtain readable counterexamples 

329 
(currently only supported by the default (exhaustive) tester). 

330 
 New counterexample generator quickcheck[narrowing] enables 

331 
narrowingbased testing. Requires the Glasgow Haskell compiler 

332 
with its installation location defined in the Isabelle settings 

333 
environment as ISABELLE_GHC. 

334 
 Removed quickcheck tester "SML" based on the SML code generator 

335 
(formly in HOL/Library). 

336 

337 
* Function package: discontinued option "tailrec". INCOMPATIBILITY, 

338 
use 'partial_function' instead. 

339 

340 
* Theory Library/Extended_Reals replaces now the positive extended 

341 
reals found in probability theory. This file is extended by 

342 
Multivariate_Analysis/Extended_Real_Limits. 

343 

44974  344 
* Theory Library/Old_Recdef: old 'recdef' package has been moved here, 
345 
from where it must be imported explicitly if it is really required. 

346 
INCOMPATIBILITY. 

44968  347 

348 
* Theory Library/Wfrec: wellfounded recursion combinator "wfrec" has 

349 
been moved here. INCOMPATIBILITY. 

350 

351 
* Theory Library/Saturated provides type of numbers with saturated 

352 
arithmetic. 

353 

354 
* Theory Library/Product_Lattice defines a pointwise ordering for the 

355 
product type 'a * 'b, and provides instance proofs for various order 

356 
and lattice type classes. 

357 

358 
* Theory Library/Countable now provides the "countable_datatype" proof 

359 
method for proving "countable" class instances for datatypes. 

360 

361 
* Theory Library/Cset_Monad allows do notation for computable sets 

362 
(cset) via the generic monad adhoc overloading facility. 

363 

364 
* Library: Theories of common data structures are split into theories 

365 
for implementation, an invariantensuring type, and connection to an 

366 
abstract type. INCOMPATIBILITY. 

367 

368 
 RBT is split into RBT and RBT_Mapping. 

369 
 AssocList is split and renamed into AList and AList_Mapping. 

370 
 DList is split into DList_Impl, DList, and DList_Cset. 

371 
 Cset is split into Cset and List_Cset. 

372 

373 
* Theory Library/Nat_Infinity has been renamed to 

374 
Library/Extended_Nat, with name changes of the following types and 

375 
constants: 

376 

377 
type inat ~> type enat 

378 
Fin ~> enat 

379 
Infty ~> infinity (overloaded)

* Session Multivariate_Analysis: The euclidean_space type class now 

387 
fixes a constant "Basis :: 'a set" consisting of the standard 

388 
orthonormal basis for the type. Users now have the option of 

389 
quantifying over this set instead of using the "basis" function, e.g. 

390 
"ALL x:Basis. P x" vs "ALL i<DIM('a). P (basis i)".

392 
* Session Multivariate_Analysis: Type "('a, 'b) cart" has been renamed 

393 
to "('a, 'b) vec" (the syntax "'a ^ 'b" remains unaffected). Constants 

394 
"Cart_nth" and "Cart_lambda" have been respectively renamed to 

395 
"vec_nth" and "vec_lambda"; theorems mentioning those names have 

396 
changed to match. Definition theorems for overloaded constants now use 

397 
the standard "foo_vec_def" naming scheme. A few other theorems have

* Records: logical foundation type for records does not carry a 
836 
'_type' suffix any longer (obsolete due to authentic syntax). 

837 
INCOMPATIBILITY. 

838 

41398  839 
* Quickcheck now by default uses exhaustive testing instead of random 
41571  840 
testing. Random testing can be invoked by "quickcheck [random]", 
841 
exhaustive testing by "quickcheck [exhaustive]". 

41398  842 

843 
* Quickcheck instantiates polymorphic types with small finite 

844 
datatypes by default. This enables a simple execution mechanism to 

845 
handle quantifiers and function equality over the finite datatypes. 

846 

41571  847 
* Quickcheck random generator has been renamed from "code" to 
848 
"random". INCOMPATIBILITY. 

41398  849 

850 
* Quickcheck now has a configurable time limit which is set to 30 

851 
seconds by default. This can be changed by adding [timeout = n] to the 

852 
quickcheck command. The time limit for Auto Quickcheck is still set 

853 
independently. 

38461  854 

855 
* Quickcheck in locales considers interpretations of that locale for 

856 
counter example search.

* Proof methods "metis" and "meson" now have configuration options 
890 
"meson_trace", "metis_trace", and "metis_verbose" that can be enabled 

891 
to diagnose these tools. E.g. 

892 

893 
using [[metis_trace = true]] 

894 

41398  895

896 
manually as command 'solve_direct'. 

897 

41601  898 
* The default SMT solver Z3 must be enabled explicitly (due to 
899 
licensing issues) by setting the environment variable 

41603  900 
Z3_NON_COMMERCIAL in etc/settings of the component, for example. For 
901 
commercial applications, the SMT solver CVC3 is provided as fallback; 

902 
changing the SMT solver is done via the configuration option 

903 
"smt_solver".

908 
* Added basic SMT support for datatypes, records, and typedefs using 

909 
the oracle mode (no proofs). Direct support of pairs has been dropped 

910 
in exchange (pass theorems fst_conv snd_conv pair_collapse to the SMT

1038 
Various operations from the Haskell prelude are used for generating 

1039

41571  1041 
* Term "bij f" is now an abbreviation of "bij_betw f UNIV UNIV". Term 
1042 
"surj f" is now an abbreviation of "range f = UNIV". The theorems 

1043 
bij_def and surj_def are unchanged. INCOMPATIBILITY.

1046 
"*" and "+" respectively. INCOMPATIBILITY.

* Name "Plus" of disjoint sum operator "<+>" is now hidden. Write 

41571  1049 
"Sum_Type.Plus" instead. 
41398  1050 

1051 
* Constant "split" has been merged with constant "prod_case"; names of 

1052 
ML functions, facts etc. involving split have been retained so far, 

1053 
though. INCOMPATIBILITY. 

1054 

1055 
* Dropped old infix syntax "_ mem _" for List.member; use "_ : set _" 

1056 
instead. INCOMPATIBILITY.

INCOMPATIBILITY. 
1060 

41594  1061

1070 
Syntax in Library/State_Monad has been changed to avoid ambiguities. 

1071 
INCOMPATIBILITY. 

1072 

1073 
* Theory Library/SetsAndFunctions has been split into

Library/Function_Algebras and Library/Set_Algebras; canonical names 

1075 
for instance definitions for functions; various improvements. 

1076 
INCOMPATIBILITY.

1078 
* Theory Library/Multiset provides stable quicksort implementation of 

1079 
sort_key. 

1080

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

1082 
INCOMPATIBILITY. 

1083 

1084 
* Session Multivariate_Analysis: introduced a type class for euclidean 

1085 
space. Most theorems are now stated in terms of euclidean spaces 

1086 
instead of finite cartesian products. 

1087 

1088 
types 

1089 
real ^ 'n ~> 'a::real_vector 

1090 
~> 'a::euclidean_space 

1091

_ $ _ ~> _ $$ _ 

1096 
\<chi> x. _ ~> \<chi>\<chi> x. _ 

1097 
CARD('n) ~> DIM('a) 

1098 

1099 
Also note that the indices are now natural numbers and not from some 

1100 
finite type. Finite cartesian products of euclidean spaces, products 

1101 
of euclidean spaces the real and complex numbers are instantiated to 

1102 
be euclidean_spaces. INCOMPATIBILITY. 

1103 

1104 
* Session Probability: introduced pextreal as positive extended real 

1105 
numbers. Use pextreal as value for measures. Introduce the 

1106 
RadonNikodym derivative, product spaces and Fubini's theorem for 

1107 
arbitrary sigma finite measures. Introduces Lebesgue measure based on 

1108 
the integral in Multivariate Analysis. INCOMPATIBILITY. 

1109 

1110 
* Session Imperative_HOL: revamped, corrected dozens of inadequacies. 

1111 
INCOMPATIBILITY. 

1112 

1113 
* Session SPARK (with image HOLSPARK) provides commands to load and 

1114

*** HOLCF *** 
1131 

1132 
* The domain package now runs in definitional mode by default: The 

41571  1133 
former command 'new_domain' is now called 'domain'. To use the domain 
40621  1134 
package in its original axiomatic mode, use 'domain (unsafe)'. 
1135 
INCOMPATIBILITY. 

1136 

41571  1137 
* The new class "domain" is now the default sort. Class "predomain" 
1138 
is an unpointed version of "domain". Theories can be updated by 

1139 
replacing sort annotations as shown below. INCOMPATIBILITY. 

40621  1140 

1141 
'a::type ~> 'a::countable 

1142 
'a::cpo ~> 'a::predomain 

1143 
'a::pcpo ~> 'a::domain 

1144 

41571  1145 
* The old type class "rep" has been superseded by class "domain". 
40621  1146 
Accordingly, users of the definitional package must remove any 
41571  1147 
"default_sort rep" declarations. INCOMPATIBILITY. 
40621  1148 

41401  1149 
* The domain package (definitional mode) now supports unpointed 
1150 
predomain argument types, as long as they are marked 'lazy'. (Strict 

41571  1151 
arguments must be in class "domain".) For example, the following 
41401  1152 
domain definition now works: 
1153 

1154 
domain natlist = nil  cons (lazy "nat discr") (lazy "natlist") 

1155 

1156 
* Theory HOLCF/Library/HOL_Cpo provides cpo and predomain class 

41571  1157 
instances for types from main HOL: bool, nat, int, char, 'a + 'b, 
1158 
'a option, and 'a list. Additionally, it configures fixrec and the 

1159 
domain package to work with these types. For example: 

41401  1160 

1161 
fixrec isInl :: "('a + 'b) u > tr" 

1162 
where "isInl$(up$(Inl x)) = TT"  "isInl$(up$(Inr y)) = FF" 

1163 

1164 
domain V = VFun (lazy "V > V")  VCon (lazy "nat") (lazy "V list") 

1165 

41571  1166 
* The "(permissive)" option of fixrec has been replaced with a 
1167 
perequation "(unchecked)" option. See 

1168 
src/HOL/HOLCF/Tutorial/Fixrec_ex.thy for examples. INCOMPATIBILITY. 

1169 

1170 
* The "bifinite" class no longer fixes a constant "approx"; the class 

1171 
now just asserts that such a function exists. INCOMPATIBILITY. 

1172 

1173 
* Former type "alg_defl" has been renamed to "defl". HOLCF no longer

of "bifinite" and "domain" classes are available in 
1176 
src/HOL/HOLCF/Library/Defl_Bifinite.thy. 

1177 

1178 
* The syntax "REP('a)" has been replaced with "DEFL('a)". 

1179 

1180 
* The predicate "directed" has been removed. INCOMPATIBILITY. 

1181 

1182 
* The type class "finite_po" has been removed. INCOMPATIBILITY. 

1183 

1184 
* The function "cprod_map" has been renamed to "prod_map". 

41401  1185 
INCOMPATIBILITY. 
1186 

1187 
* The monadic bind operator on each powerdomain has new binder syntax 

41571  1188 
similar to sets, e.g. "\<Union>\<sharp>x\<in>xs. t" represents 
1189 
"upper_bind\<cdot>xs\<cdot>(\<Lambda> x. t)". 

41401  1190 

1191 
* The infix syntax for binary union on each powerdomain has changed 

41571  1192 
from e.g. "+\<sharp>" to "\<union>\<sharp>", for consistency with set 
1193 
syntax. INCOMPATIBILITY. 

1194

1221 
* Various changes to bisimulation/coinduction with domain package: 

41571  1222 

1223 
 Definitions of "bisim" constants no longer mention definedness. 

1224 
 With mutual recursion, "bisim" predicate is now curried. 

40621  1225 
 With mutual recursion, each type gets a separate coind theorem. 
1226 
 Variable names in bisim_def and coinduct rules have changed.

* Parallel and asynchronous execution requires special care concerning 
1370 
interrupts. Structure Exn provides some convenience functions that 

1371 
avoid working directly with raw Interrupt. User code must not absorb 

1372 
interrupts  intermediate handling (for cleanup etc.) needs to be 

1373 
followed by reraising of the original exception. Another common 

1374 
source of mistakes are "handle _" patterns, which make the meaning of 

1375 
the program subject to physical effects of the environment.

* Authentic syntax for *all* logical entities (type classes, type 
1385 
constructors, term constants): provides simple and robust 

1386 
correspondence between formal entities and concrete syntax. Within 

1387 
the parse tree / AST representations, "constants" are decorated by 

1388 
their category (class, type, const) and spelled out explicitly with 

1389 
their full internal name.

Substantial INCOMPATIBILITY concerning lowlevel syntax declarations 

1392 
and translations (translation rules and translation functions in ML). 

1393 
Some hints on upgrading: 

35260  1394 

1395 
 Many existing uses of 'syntax' and 'translations' can be replaced 

35436  1396 
by more modern 'type_notation', 'notation' and 'abbreviation', 
1397 
which are independent of this issue. 

35260  1398 

1399 
 'translations' require markup within the AST; the term syntax 

1400 
provides the following special forms: 

1401 

1402 
CONST c  produces syntax version of constant c from context 

35261  1403 
XCONST c  literally c, checked as constant from context
