107 
INCOMPATIBILITY. 

108 

52430  109 
* Proper diagnostic command 'print_state'. Old 'pr' (with its 
110 
implicit change of some global references) is retained for now as 

111 
control command, e.g. for ProofGeneral 3.7.x. 

112

114 
and Unix commandline print spooling. Minor INCOMPATIBILITY: use 

115 
'display_drafts' instead and print via the regular document viewer. 

116

*** Prover IDE  Isabelle/Scala/jEdit *** 
122 

53971  123 
* New manual "jedit" for Isabelle/jEdit, see isabelle doc or 
53852  124 
Documentation panel. 
125 

53971  126 
* Dockable window "Documentation" provides access to Isabelle 
127 
documentation. 

52646  128 

52949  129 
* Dockable window "Find" provides query operations for formal entities 
130 
(GUI frontend to 'find_theorems' command). 

131 

53050  132 
* Dockable window "Sledgehammer" manages asynchronous / parallel 
133 
sledgehammer runs over existing document sources, independently of 

134 
normal editing and checking process. 

135 

51533  136 
* Dockable window "Timing" provides an overview of relevant command 
54332  137 
timing information, depending on option jedit_timing_threshold. The 
138 
same timing information is shown in the extended tooltip of the 

139 
command keyword, when hovering the mouse over it while the CONTROL or 

140 
COMMAND modifier is pressed. 

51533  141 

53971  142 
* Improved dockable window "Theories": Continuous checking of proof 
143 
document (visible and required parts) may be controlled explicitly, 

144 
using check box or shortcut "C+e ENTER". Individual theory nodes may 

145 
be marked explicitly as required and checked in full, using check box 

146 
or shortcut "C+e SPACE". 

147 

54305  148 
* Improved completion mechanism, which is now managed by the 
149 
Isabelle/jEdit plugin instead of SideKick. Refined table of Isabelle 

150 
symbol abbreviations (see $ISABELLE_HOME/etc/symbols). 

151 

54319  152 
* Standard jEdit keyboard shortcut C+b completeword is remapped to 
153 
isabelle.complete for explicit completion in Isabelle sources. 

154 
INCOMPATIBILITY wrt. jEdit defaults, may have to invent new shortcuts 

155 
to resolve conflict. 

156 

54305  157 
* Improved support of various "minor modes" for Isabelle NEWS, 
158 
options, session ROOT etc., with completion and SideKick tree view. 

159 

53971  160 
* Strictly monotonic document update, without premature cancellation of 
161 
running transactions that are still needed: avoid reset/restart of 

162 
such command executions while editing.

168 
toplevel theorem statements.

177 
obsolete $ISABELLE_HOME_WINDOWS variable. 

53971  178 

179 
* Improved support for Linux lookandfeel "GTK+", see also "Utilities 

180

181 

182 
* Improved support of native Mac OS X functionality via "MacOSX" 

183

* Commands 'interpretation' and 'sublocale' are now targetsensitive. 
189 
In particular, 'interpretation' allows for nonpersistent 

190 
interpretation within "context ... begin ... end" blocks offering a 

191 
lightweight alternative to 'sublocale'. See "isarref" manual for 

192 
details. 

51747  193 

51565  194 
* Improved locales diagnostic command 'print_dependencies'. 
195 

51313  196 
* Discontinued obsolete 'axioms' command, which has been marked as 
197 
legacy since Isabelle20092. INCOMPATIBILITY, use 'axiomatization' 

198

* System option "proofs" has been discontinued. Instead the global 
204 
state of Proofterm.proofs is persistently compiled into logic images 

205 
as required, notably HOLProofs. Users no longer need to change 

206 
Proofterm.proofs dynamically. Minor INCOMPATIBILITY. 

207 

208 
* Syntax translation functions (print_translation etc.) always depend 

209 
on Proof.context. Discontinued former "(advanced)" option  this is 

210 
now the default. Minor INCOMPATIBILITY. 

211 

212 
* Former global reference trace_unify_fail is now available as 

213 
configuration option "unify_trace_failure" (global context only). 

214 

52463  215 
* SELECT_GOAL now retains the syntactic context of the overall goal 
216 
state (schematic variables etc.). Potential INCOMPATIBILITY in rare 

217 
situations.

248 
* Discontinued theories Code_Integer and Efficient_Nat by a more 

249 
finegrain stack of theories Code_Target_Int, Code_Binary_Nat, 

250 
Code_Target_Nat and Code_Target_Numeral. See the tutorial on code 

251 
generation for details. INCOMPATIBILITY. 

252 

253 
* Numeric types are mapped by default to target language numerals: 

254 
natural (replaces former code_numeral) and integer (replaces former 

255 
code_int). Conversions are available as integer_of_natural / 

256 
natural_of_integer / integer_of_nat / nat_of_integer (in HOL) and 

257 
Code_Numeral.integer_of_natural / Code_Numeral.natural_of_integer (in

* Function package: For mutually recursive functions f and g, separate 

261 
cases rules f.cases and g.cases are generated instead of unusable 

262 
f_g.cases which exposed internal sum types. Potential INCOMPATIBILITY, 

263 
in the case that the unusable rule was used nevertheless. 

264 

265 
* Function package: For each function f, new rules f.elims are 

266 
generated, which eliminate equalities of the form "f x = t". 

267 

268 
* New command 'fun_cases' derives adhoc elimination rules for 

269 
function equations as simplified instances of f.elims, analogous to 

270 
inductive_cases. See ~~/src/HOL/ex/Fundefs.thy for some examples.

 parametrized correspondence relations are now supported: 

54378  274 
+ parametricity theorems for the raw term can be specified in 
54021  275 
the command lift_definition, which allow us to generate stronger 
276 
transfer rules 

277 
+ setup_lifting generates stronger transfer rules if parametric 

278 
correspondence relation can be generated 

279 
+ various new properties of the relator must be specified to support 

280 
parametricity 

281

282 
 setup_lifting generates domain rules for the Transfer package 

283

284

285 
 ===> and > are now local. The symbols can be introduced 

286 
by interpreting the locale lifting_syntax (typically in an 

287

298

* Reification and reflection: 
53160  304 
 Reification is now directly available in HOLMain in structure 
305 
"Reification". 

306 
 Reflection now handles multiple lists with variables also. 

307 
 The whole reflection stack has been decomposed into conversions. 

52286  308 
INCOMPATIBILITY. 
309 

51489  310 
* Revised devices for recursive definitions over finite sets: 
311 
 Only one fundamental fold combinator on finite set remains: 

312 
Finite_Set.fold :: ('a => 'b => 'b) => 'b => 'a set => 'b 

313

319 
Note that foundational constants comm_monoid_set.F and 

320

321 
and fold1 respectively. These are now gone. You may use 

51490  322

334 
ccpo, but with mandatory prefix ccpo. Admissibility theorems lose the 

335

53362  336 
INCOMPATIBILITY. 
337 

53160  338 
* Introduce type class "conditionally_complete_lattice": Like a 
339 
complete lattice but does not assume the existence of the top and 

340 
bottom elements. Allows to generalize some lemmas about reals and 

341 
extended reals. Removed SupInf and replaced it by the instantiation 

342 
of conditionally_complete_lattice for real. Renamed lemmas about 

343 
conditionallycomplete lattice from Sup_... to cSup_... and from 

344 
Inf_... to cInf_... to avoid hidding of similar complete lattice 

345 
lemmas. 

346 

347 
* Introduce type class linear_continuum as combination of 

348 
conditionallycomplete lattices and inner dense linorders which have 

349 
more than one element. INCOMPATIBILITY. 

350 

53983  351 
* Introduced type classes order_top and order_bot. The old classes top 
352 
and bot only contain the syntax without assumptions. INCOMPATIBILITY: 

353 
Rename bot > order_bot, top > order_top 

53683  354 

53160  355 
* Introduce type classes "no_top" and "no_bot" for orderings without 
356 
top and bottom elements. 

51732  357 

358 
* Split dense_linorder into inner_dense_order and no_top, no_bot. 

359

53160  361 
HOLMultivariate_Analysis to HOLComplex_Main. 
51732  362 

53983  363 
 Introduce type class (lin)order_topology and 
364 
linear_continuum_topology. Allows to generalize theorems about 

365 
limits and order. Instances are reals and extended reals. 

51732  366 

367 
 continuous and continuos_on from Multivariate_Analysis: 

53983  368 
"continuous" is the continuity of a function at a filter. "isCont" 
369 
is now an abbrevitation: "isCont x f == continuous (at _) f". 

370 

371 
Generalized continuity lemmas from isCont to continuous on an 

372 
arbitrary filter. 

373 

374 
 compact from Multivariate_Analysis. Use Bolzano's lemma to prove 

375 
compactness of closed intervals on reals. Continuous functions 

376 
attain infimum and supremum on compact sets. The inverse of a 

377 
continuous function is continuous, when the function is continuous 

378 
on a compact set.

388 
 FDERIV: Definition of has_derivative moved to Deriv.thy. Moved 

389 
theorems from Library/FDERIV.thy to Deriv.thy and base the 

390 
definition of DERIV on FDERIV. Add variants of DERIV and FDERIV 

391 
which are restricted to sets, i.e. to represent derivatives from 

392 
left or right. 

51732  393 

394 
 Removed the withinfilter. It is replaced by the principal filter: 

395 

396 
F within X = inf F (principal X) 

397 

398 
 Introduce "at x within U" as a single constant, "at x" is now an 

399 
abbreviation for "at x within UNIV" 

400 

53983  401 
 Introduce named theorem collections tendsto_intros, 
402 
continuous_intros, continuous_on_intros and FDERIV_intros. Theorems 

403 
in tendsto_intros (or FDERIV_intros) are also available as 

404 
tendsto_eq_intros (or FDERIV_eq_intros) where the righthand side 

405 
is replaced by a congruence rule. This allows to apply them as 

406 
intro rules and then proving equivalence by the simplifier.

*** Prover IDE  Isabelle/Scala/jEdit *** 
633 

634 
* Parallel terminal proofs ('by') are enabled by default, likewise 

635 
proofs that are built into packages like 'datatype', 'function'. This 

636 
allows to "run ahead" checking the theory specifications on the 

637 
surface, while the prover is still crunching on internal 

638 
justifications. Unfinished / cancelled proofs are restarted as 

639 
required to complete full proof checking eventually. 

640 

641 
* Improved output panel with tooltips, hyperlinks etc. based on the 

642 
same Rich_Text_Area as regular Isabelle/jEdit buffers. Activation of 

643 
tooltips leads to some window that supports the same recursively, 

644 
which can lead to stacks of tooltips as the semantic document content 

645 
is explored. ESCAPE closes the whole stack, individual windows may be 

646 
closed separately, or detached to become independent jEdit dockables. 

647 

50717  648 
* Improved support for commands that produce graph output: the text 
649 
message contains a clickable area to open a new instance of the graph 

650 
browser on demand. 

651 

49968  652 
* More robust incremental parsing of outer syntax (partial comments, 
653 
malformed symbols). Changing the balance of open/close quotes and 

654 
comment delimiters works more conveniently with unfinished situations 

655 
that frequently occur in user interaction. 

656 

657 
* More efficient painting and improved reactivity when editing large 

658 
files. More scalable management of formal document content.

* Generalized the definition of limits: 

797 

798 
 Introduced the predicate filterlim (LIM x F. f x :> G) which 

799 
expresses that when the input values x converge to F then the 

800 
output f x converges to G. 

801 

802 
 Added filters for convergence to positive (at_top) and negative 

803 
infinity (at_bot). 

804 

805 
 Moved infinity in the norm (at_infinity) from 

806 
Multivariate_Analysis to Complex_Main. 

807 

808

828 
prefix ~> prefixeq 

829 
strict_prefix ~> prefix 

830 

50646  831 
 Replaced constant "postfix" by "suffixeq" with swapped argument 
832 
order (i.e., "postfix xs ys" is now "suffixeq ys xs") and dropped 

833 
old infix syntax "xs >>= ys"; use "suffixeq ys xs" instead. 

834 
Renamed lemmas accordingly. 

835 

836 
 Added constant "list_hembeq" for homeomorphic embedding on 

837 
lists. Added abbreviation "sublisteq" for special case 

838 
"list_hembeq (op =)". 

839 

840 
 Theory Library/Sublist no longer provides "order" and "bot" type 

841 
class instances for the prefix order (merely corresponding locale 

842 
interpretations). The type class instances are now in theory 

843 
Library/Prefix_Order. 

844 

845 
 The sublist relation of theory Library/Sublist_Order is now based 

846

869 
* Theory Library/Debug and Library/Parallel provide debugging and 

870 
parallel execution for code generated towards Isabelle/ML. 

871 

872 
* Theory Library/FuncSet: Extended support for Pi and extensional and 

873 
introduce the extensional dependent function space "PiE". Replaced 

874 
extensional_funcset by an abbreviation, and renamed lemmas from 

875 
extensional_funcset to PiE as follows: 

876 

877 
extensional_empty ~> PiE_empty

890 
* Theory Library/FinFun: theory of almost everywhere constant 

891 
functions (supersedes the AFP entry "Code Generation for Functions as 

892 
Data"). 

893 

894 
* Theory Library/Phantom: generic phantom type to make a type 

895 
parameter appear in a constant's type. This alternative to adding 

896 
TYPE('a) as another parameter avoids unnecessary closures in generated 

897 
code. 

898 

899 
* Theory Library/RBT_Impl: efficient construction of redblack trees 

900 
from sorted associative lists. Merging two trees with rbt_union may 

901 
return a structurally different tree than before. Potential 

902 
INCOMPATIBILITY.

* Bundled declarations associate attributed fact expressions with a 
1106 
given name in the context. These may be later included in other 

1107 
contexts. This allows to manage context extensions casually, without 

47855  1108 
the logical dependencies of locales and locale interpretation. See 
1109 
commands 'bundle', 'include', 'including' etc. in the isarref manual. 

47484  1110 

47829  1111 
* Commands 'lemmas' and 'theorems' allow local variables using 'for' 
1112 
declaration, and results are standardized before being stored. Thus 

1113 
oldstyle "standard" after instantiation or composition of facts 

1114 
becomes obsolete. Minor INCOMPATIBILITY, due to potential change of 

1115 
indices of schematic variables. 

1116 

1117 
* Rule attributes in local theory declarations (e.g. locale or class) 

1118 
are now statically evaluated: the resulting theorem is stored instead 

1119 
of the original expression. INCOMPATIBILITY in rare situations, where 

1120 
the historic accident of dynamic reevaluation in interpretations 

1121 
etc. was exploited. 

1122 

1123 
* New tutorial "Programming and Proving in Isabelle/HOL" 

1124 
("progprove"). It completely supersedes "A Tutorial Introduction to 

1125 
Structured Isar Proofs" ("isaroverview"), which has been removed. It 

1126 
also supersedes "Isabelle/HOL, A Proof Assistant for HigherOrder 

1127 
Logic" as the recommended beginners tutorial, but does not cover all 

1128 
of the material of that old tutorial. 

1129 

1130 
* Updated and extended reference manuals: "isarref", 

1131 
"implementation", "system"; reduced remaining material in old "ref" 

1132 
manual.

47855  1141 
* Attribute "abs_def" turns an equation of the form "f x y == t" into 
1142 
"f == %x y. t", which ensures that "simp" or "unfold" steps always 

1143 
expand it. This also works for objectlogic equality. (Formerly 

1144 
undocumented feature.) 

1145 

47856  1146 
* Sort constraints are now propagated in simultaneous statements, just 
1147 
like type constraints. INCOMPATIBILITY in rare situations, where 

1148 
distinct sorts used to be assigned accidentally. For example: 

1149 

1150 
lemma "P (x::'a::foo)" and "Q (y::'a::bar)"  "now illegal" 

1151 

1152 
lemma "P (x::'a)" and "Q (y::'a::bar)" 

1153 
 "now uniform 'a::bar instead of default sort for first occurrence (!)" 

1154 

1155 
* Rule composition via attribute "OF" (or ML functions OF/MRS) is more 

1156 
tolerant against multiple unifiers, as long as the final result is 

1157 
unique. (As before, rules are composed in canonical righttoleft 

1158 
order to accommodate newly introduced premises.) 

1159 

47806  1160 
* Renamed some inner syntax categories: 
1161 

1162 
num ~> num_token 

1163 
xnum ~> xnum_token 

1164 
xstr ~> str_token 

1165 

1166 
Minor INCOMPATIBILITY. Note that in practice "num_const" or 

1167 
"num_position" etc. are mainly used instead (which also include 

1168 
position information via constraints). 

1169 

47829  1170 
* Simplified configuration options for syntax ambiguity: see 
1171 
"syntax_ambiguity_warning" and "syntax_ambiguity_limit" in isarref 

1172 
manual. Minor INCOMPATIBILITY. 

1173 

47856  1174 
* Discontinued configuration option "syntax_positions": atomic terms 
1175

47464  1201 
* Type 'a set is now a proper type constructor (just as before 
1202 
Isabelle2008). Definitions mem_def and Collect_def have disappeared. 

1203 
Nontrivial INCOMPATIBILITY. For developments keeping predicates and 

47855  1204 
sets separate, it is often sufficient to rephrase some set S that has 
1205 
been accidentally used as predicates by "%x. x : S", and some 

1206 
predicate P that has been accidentally used as set by "{x. P x}". 

1207 
Corresponding proofs in a first step should be pruned from any 

1208 
tinkering with former theorems mem_def and Collect_def as far as 

1209 
possible. 

1210 

1211 
For developments which deliberately mix predicates and sets, a 

47464  1212 
planning step is necessary to determine what should become a predicate 
1213 
and what a set. It can be helpful to carry out that step in 

1214 
Isabelle20111 before jumping right into the current release. 

1215

1223

47855  1224 
positive and negated numeric literals, respectively. See also 
1225 
definitions in ~~/src/HOL/Num.thy. Potential INCOMPATIBILITY, some

47855  1245 
* Transfer: New package intended to generalize the existing 
1246 
"descending" method and related theorem attributes from the Quotient 

1247 
package. (Not all functionality is implemented yet, but future 

1248 
development will focus on Transfer as an eventual replacement for the 

1249 
corresponding parts of the Quotient package.) 

47809  1250 

1251 
 transfer_rule attribute: Maintains a collection of transfer rules, 

1252 
which relate constants at two different types. Transfer rules may 

1253 
relate different type instances of the same polymorphic constant, 

1254 
or they may relate an operation on a raw type to a corresponding 

1255 
operation on an abstract type (quotient or subtype). For example: 

1256 

1257 
((A ===> B) ===> list_all2 A ===> list_all2 B) map map 

1258 
(cr_int ===> cr_int ===> cr_int) (%(x,y) (u,v). (x+u, y+v)) plus_int 

1259 

1260 
 transfer method: Replaces a subgoal on abstract types with an 

1261 
equivalent subgoal on the corresponding raw types. Constants are 

1262 
replaced with corresponding ones according to the transfer rules. 

1263 
Goals are generalized over all free variables by default; this is 

47851  1264 
necessary for variables whose types change, but can be overridden 
47855  1265 
for specific variables with e.g. "transfer fixing: x y z". The 
47809  1266 
variant transfer' method allows replacing a subgoal with one that 
1267 
is logically stronger (rather than equivalent). 

1268 

1269 
 relator_eq attribute: Collects identity laws for relators of 

1270 
various type constructors, e.g. "list_all2 (op =) = (op =)". The 

1271 
transfer method uses these lemmas to infer transfer rules for 

1272 
nonpolymorphic constants on the fly. 

1273 

1274 
 transfer_prover method: Assists with proving a transfer rule for a 

1275 
new constant, provided the constant is defined in terms of other 

1276 
constants that already have transfer rules. It should be applied 

1277 
after unfolding the constant definitions. 

1278 

1279 
 HOL/ex/Transfer_Int_Nat.thy: Example theory demonstrating transfer 

1280 
from type nat to type int. 

1281 

47851  1282 
* Lifting: New package intended to generalize the quotient_definition 
1283 
facility of the Quotient package; designed to work with Transfer. 

47809  1284 

1285 
 lift_definition command: Defines operations on an abstract type in 

1286 
terms of a corresponding operation on a representation 

1287 
type. Example syntax: 

1288 

1289 
lift_definition dlist_insert :: "'a => 'a dlist => 'a dlist" 

1290 
is List.insert 

1291 

1292 
Users must discharge a respectfulness proof obligation when each 

1293 
constant is defined. (For a type copy, i.e. a typedef with UNIV, 

1294 
the proof is discharged automatically.) The obligation is 

1295 
presented in a userfriendly, readable form; a respectfulness 

1296 
theorem in the standard format and a transfer rule are generated 

1297 
by the package. 

1298 

1299 
 Integration with code_abstype: For typedefs (e.g. subtypes 

1300 
corresponding to a datatype invariant, such as dlist), 

1301 
lift_definition generates a code certificate theorem and sets up 

1302 
code generation for each constant. 

1303 

1304 
 setup_lifting command: Sets up the Lifting package to work with a 

1305 
userdefined type. The user must provide either a quotient theorem 

1306 
or a type_definition theorem. The package configures transfer 

1307 
rules for equality and quantifiers on the type, and sets up the 

1308 
lift_definition command to work with the type. 

1309 

1310 
 Usage examples: See Quotient_Examples/Lift_DList.thy, 

47851  1311 
Quotient_Examples/Lift_RBT.thy, Quotient_Examples/Lift_FSet.thy, 
1312 
Word/Word.thy and Library/Float.thy. 

47809  1313 

1314 
* Quotient package: 

1315 

1316 
 The 'quotient_type' command now supports a 'morphisms' option with 

1317 
rep and abs functions, similar to typedef. 

1318 

1319 
 'quotient_type' sets up new types to work with the Lifting and 

1320 
Transfer packages, as with 'setup_lifting'. 

1321 

1322 
 The 'quotient_definition' command now requires the user to prove a 

1323 
respectfulness property at the point where the constant is 

1324 
defined, similar to lift_definition; INCOMPATIBILITY. 

1325 

1326 
 Renamed predicate 'Quotient' to 'Quotient3', and renamed theorems 

1327 
accordingly, INCOMPATIBILITY. 

1328 

1329 
* New diagnostic command 'find_unused_assms' to find potentially 

1330 
superfluous assumptions in theorems using Quickcheck. 

1331 

1332 
* Quickcheck: 

1333 

1334 
 Quickcheck returns variable assignments as counterexamples, which 

1335 
allows to reveal the underspecification of functions under test. 

1336 
For example, refuting "hd xs = x", it presents the variable 

1337 
assignment xs = [] and x = a1 as a counterexample, assuming that 

1338 
any property is false whenever "hd []" occurs in it. 

1339 

1340 
These counterexample are marked as potentially spurious, as 

1341 
Quickcheck also returns "xs = []" as a counterexample to the 

1342 
obvious theorem "hd xs = hd xs". 

1343 

1344 
After finding a potentially spurious counterexample, Quickcheck 

1345 
continues searching for genuine ones. 

1346 

1347 
By default, Quickcheck shows potentially spurious and genuine 

1348 
counterexamples. The option "genuine_only" sets quickcheck to only 

1349 
show genuine counterexamples. 

1350 

1351 
 The command 'quickcheck_generator' creates random and exhaustive 

1352 
value generators for a given type and operations. 

1353 

1354 
It generates values by using the operations as if they were 

1355 
constructors of that type. 

1356 

1357 
 Support for multisets. 

1358 

1359 
 Added "use_subtype" options. 

1360 

1361 
 Added "quickcheck_locale" configuration to specify how to process 

1362 
conjectures in a locale context. 

1363 

47855  1364 
* Nitpick: Fixed infinite loop caused by the 'peephole_optim' option 
1365 
and affecting 'rat' and 'real'. 

47809  1366 

1367 
* Sledgehammer: 

1368 
 Integrated more tightly with SPASS, as described in the ITP 2012 

1369 
paper "More SPASS with Isabelle". 

1370 
 Made it try "smt" as a fallback if "metis" fails or times out. 

1371 
 Added support for the following provers: AltErgo (via Why3 and 

1372 
TFF1), iProver, iProverEq. 

1373 
 Sped up the minimizer. 

1374 
 Added "lam_trans", "uncurry_aliases", and "minimize" options. 

1375 
 Renamed "slicing" ("no_slicing") option to "slice" ("dont_slice"). 

1376 
 Renamed "sound" option to "strict". 

1377 

47855  1378 
* Metis: Added possibility to specify lambda translations scheme as a 
1379 
parenthesized argument (e.g., "by (metis (lifting) ...)").

* SMT: Renamed "smt_fixed" option to "smt_read_only_certificates". 

1382 

1383 
* Command 'try0': Renamed from 'try_methods'. INCOMPATIBILITY. 

47809  1384 

47856  1385 
* New "case_product" attribute to generate a case rule doing multiple 
1386 
case distinctions at the same time. E.g. 

1387 

1388 
list.exhaust [case_product nat.exhaust] 

1389 

1390 
produces a rule which can be used to perform case distinction on both 

1391 
a list and a nat. 

1392 

47809  1393 
* New "eventually_elim" method as a generalized variant of the 
47855  1394 
eventually_elim* rules. Supports structured proofs.

* Record: code generation can be switched off manually with 
1401 

1402 
declare [[record_coden = false]]  "default true" 

1403 

1404 
* Datatype: type parameters allow explicit sort constraints. 

1405 

47855  1406 
* Concrete syntax for case expressions includes constraints for source 
1407 
positions, and thus produces Prover IDE markup for its bindings. 

1408 
INCOMPATIBILITY for oldstyle syntax translations that augment the 

1409 
pattern notation; e.g. see src/HOL/HOLCF/One.thy for translations of 

1410 
one_case. 

1411 

1412 
* Clarified attribute "mono_set": pure declaration without modifying 

1413 
the result of the fact expression.
