13 
not check existence within the filesystem. 

14 

54732  15 
* Discontinued legacy_isub_isup, which was a temporary Isabelle/ML 
16 
workaround in Isabelle20131. The prover process no longer accepts 

17 
old identifier syntax with \<^isub> or \<^isup>.

* Auxiliary files ('ML_file' etc.) are managed by the Prover IDE. 

23 
Open text buffers take precedence over copies within the filesystem. 

24 

54688  25 
* Document panel: simplied interaction where every single mouse click

368

369 

370 
* Function package: For each function f, new rules f.elims are 

371 
generated, which eliminate equalities of the form "f x = t".

445 
bottom elements. Allows to generalize some lemmas about reals and 

446 
extended reals. Removed SupInf and replaced it by the instantiation 

447

450 
lemmas.

*** Prover IDE  Isabelle/Scala/jEdit *** 
738 

739 
* Parallel terminal proofs ('by') are enabled by default, likewise 

740 
proofs that are built into packages like 'datatype', 'function'. This 

741 
allows to "run ahead" checking the theory specifications on the 

742 
surface, while the prover is still crunching on internal 

743 
justifications. Unfinished / cancelled proofs are restarted as 

744 
required to complete full proof checking eventually. 

745 

746 
* Improved output panel with tooltips, hyperlinks etc. based on the 

747 
same Rich_Text_Area as regular Isabelle/jEdit buffers. Activation of 

748 
tooltips leads to some window that supports the same recursively, 

749 
which can lead to stacks of tooltips as the semantic document content 

750 
is explored. ESCAPE closes the whole stack, individual windows may be 

751 
closed separately, or detached to become independent jEdit dockables. 

752 

50717  753 
* Improved support for commands that produce graph output: the text 
754 
message contains a clickable area to open a new instance of the graph 

755 
browser on demand. 

756 

49968  757 
* More robust incremental parsing of outer syntax (partial comments, 
758 
malformed symbols). Changing the balance of open/close quotes and 

759 
comment delimiters works more conveniently with unfinished situations 

760 
that frequently occur in user interaction. 

761 

762 
* More efficient painting and improved reactivity when editing large 

763 
files. More scalable management of formal document content.

771 
jEdit plugin option panel provides access to some Isabelle/Scala 

772 
options, including tuning parameters for editor reactivity and color 

773

774

905 
output f x converges to G. 

906

908 
infinity (at_bot).

934 
strict_prefix ~> prefix 

935 

50646  936 
 Replaced constant "postfix" by "suffixeq" with swapped argument 
937 
order (i.e., "postfix xs ys" is now "suffixeq ys xs") and dropped 

938 
old infix syntax "xs >>= ys"; use "suffixeq ys xs" instead. 

939 
Renamed lemmas accordingly. 

940 

941 
 Added constant "list_hembeq" for homeomorphic embedding on 

942 
lists. Added abbreviation "sublisteq" for special case 

943 
"list_hembeq (op =)". 

944 

945 
 Theory Library/Sublist no longer provides "order" and "bot" type 

946 
class instances for the prefix order (merely corresponding locale 

947 
interpretations). The type class instances are now in theory 

948 
Library/Prefix_Order. 

949 

950 
 The sublist relation of theory Library/Sublist_Order is now based

978 
introduce the extensional dependent function space "PiE". Replaced 

979

996 
functions (supersedes the AFP entry "Code Generation for Functions as 

997

998 

999 
* Theory Library/Phantom: generic phantom type to make a type 

1000 
parameter appear in a constant's type. This alternative to adding 

1001 
TYPE('a) as another parameter avoids unnecessary closures in generated 

1002 
code. 

1003 

1004 
* Theory Library/RBT_Impl: efficient construction of redblack trees 

1005 
from sorted associative lists. Merging two trees with rbt_union may 

1006 
return a structurally different tree than before. Potential

* Bundled declarations associate attributed fact expressions with a 
1211 
given name in the context. These may be later included in other 

1212 
contexts. This allows to manage context extensions casually, without 

47855  1213 
the logical dependencies of locales and locale interpretation. See 
1214 
commands 'bundle', 'include', 'including' etc. in the isarref manual. 

47484  1215 

47829  1216 
* Commands 'lemmas' and 'theorems' allow local variables using 'for' 
1217 
declaration, and results are standardized before being stored. Thus 

1218 
oldstyle "standard" after instantiation or composition of facts 

1219 
becomes obsolete. Minor INCOMPATIBILITY, due to potential change of 

1220 
indices of schematic variables. 

1221 

1222 
* Rule attributes in local theory declarations (e.g. locale or class) 

1223 
are now statically evaluated: the resulting theorem is stored instead 

1224 
of the original expression. INCOMPATIBILITY in rare situations, where 

1225 
the historic accident of dynamic reevaluation in interpretations 

1226 
etc. was exploited.

1231 
also supersedes "Isabelle/HOL, A Proof Assistant for HigherOrder 

1232 
Logic" as the recommended beginners tutorial, but does not cover all 

1233 
of the material of that old tutorial.

47855  1246 
* Attribute "abs_def" turns an equation of the form "f x y == t" into 
1247 
"f == %x y. t", which ensures that "simp" or "unfold" steps always 

1248 
expand it. This also works for objectlogic equality. (Formerly 

1249 
undocumented feature.) 

1250 

47856  1251 
* Sort constraints are now propagated in simultaneous statements, just 
1252 
like type constraints. INCOMPATIBILITY in rare situations, where 

1253 
distinct sorts used to be assigned accidentally. For example: 

1254 

1255 
lemma "P (x::'a::foo)" and "Q (y::'a::bar)"  "now illegal" 

1256 

1257 
lemma "P (x::'a)" and "Q (y::'a::bar)" 

1258 
 "now uniform 'a::bar instead of default sort for first occurrence (!)" 

1259 

1260 
* Rule composition via attribute "OF" (or ML functions OF/MRS) is more 

1261 
tolerant against multiple unifiers, as long as the final result is 

1262 
unique. (As before, rules are composed in canonical righttoleft 

1263 
order to accommodate newly introduced premises.) 

1264 

47806  1265 
* Renamed some inner syntax categories: 
1266 

1267 
num ~> num_token 

1268 
xnum ~> xnum_token 

1269 
xstr ~> str_token 

1270 

1271 
Minor INCOMPATIBILITY. Note that in practice "num_const" or 

1272 
"num_position" etc. are mainly used instead (which also include 

1273 
position information via constraints). 

1274 

47829  1275 
* Simplified configuration options for syntax ambiguity: see

* Type 'a set is now a proper type constructor (just as before

1308 
Nontrivial INCOMPATIBILITY. For developments keeping predicates and 

47855  1309 
sets separate, it is often sufficient to rephrase some set S that has 
1310 
been accidentally used as predicates by "%x. x : S", and some 

1311 
predicate P that has been accidentally used as set by "{x. P x}". 

1312 
Corresponding proofs in a first step should be pruned from any 

1313 
tinkering with former theorems mem_def and Collect_def as far as 

1314 
possible. 

1315 

1316 
For developments which deliberately mix predicates and sets, a 

47464  1317 
planning step is necessary to determine what should become a predicate 
1318

* The representation of numerals has changed. Datatype "num" 
1327 
represents strictly positive binary numerals, along with functions 

1328 
"numeral :: num => 'a" and "neg_numeral :: num => 'a" to represent 

47855  1329 
positive and negated numeric literals, respectively. See also 
1330 
definitions in ~~/src/HOL/Num.thy. Potential INCOMPATIBILITY, some 

1331 
user theories may require adaptations as follows:

47855  1350 
* Transfer: New package intended to generalize the existing 
1351 
"descending" method and related theorem attributes from the Quotient 

1352 
package. (Not all functionality is implemented yet, but future 

1353 
development will focus on Transfer as an eventual replacement for the 

1354 
corresponding parts of the Quotient package.) 

47809  1355 

1356 
 transfer_rule attribute: Maintains a collection of transfer rules, 

1357 
which relate constants at two different types. Transfer rules may 

1358 
relate different type instances of the same polymorphic constant, 

1359 
or they may relate an operation on a raw type to a corresponding 

1360 
operation on an abstract type (quotient or subtype). For example: 

1361 

1362 
((A ===> B) ===> list_all2 A ===> list_all2 B) map map 

1363 
(cr_int ===> cr_int ===> cr_int) (%(x,y) (u,v). (x+u, y+v)) plus_int 

1364 

1365 
 transfer method: Replaces a subgoal on abstract types with an 

1366 
equivalent subgoal on the corresponding raw types. Constants are 

1367 
replaced with corresponding ones according to the transfer rules. 

1368 
Goals are generalized over all free variables by default; this is 

47851  1369 
necessary for variables whose types change, but can be overridden 
47855  1370 
for specific variables with e.g. "transfer fixing: x y z". The 
47809  1371 
variant transfer' method allows replacing a subgoal with one that 
1372 
is logically stronger (rather than equivalent). 

1373 

1374 
 relator_eq attribute: Collects identity laws for relators of 

1375 
various type constructors, e.g. "list_all2 (op =) = (op =)". The 

1376 
transfer method uses these lemmas to infer transfer rules for 

1377 
nonpolymorphic constants on the fly. 

1378 

1379 
 transfer_prover method: Assists with proving a transfer rule for a 

1380 
new constant, provided the constant is defined in terms of other 

1381 
constants that already have transfer rules. It should be applied 

1382 
after unfolding the constant definitions. 

1383 

1384 
 HOL/ex/Transfer_Int_Nat.thy: Example theory demonstrating transfer 

1385 
from type nat to type int. 

1386 

47851  1387 
* Lifting: New package intended to generalize the quotient_definition 
1388 
facility of the Quotient package; designed to work with Transfer. 

47809  1389 

1390 
 lift_definition command: Defines operations on an abstract type in 

1391 
terms of a corresponding operation on a representation 

1392 
type. Example syntax: 

1393 

1394 
lift_definition dlist_insert :: "'a => 'a dlist => 'a dlist" 

1395 
is List.insert 

1396 

1397 
Users must discharge a respectfulness proof obligation when each 

1398 
constant is defined. (For a type copy, i.e. a typedef with UNIV, 

1399 
the proof is discharged automatically.) The obligation is 

1400 
presented in a userfriendly, readable form; a respectfulness 

1401 
theorem in the standard format and a transfer rule are generated 

1402 
by the package. 

1403 

1404 
 Integration with code_abstype: For typedefs (e.g. subtypes 

1405 
corresponding to a datatype invariant, such as dlist), 

1406 
lift_definition generates a code certificate theorem and sets up 

1407 
code generation for each constant. 

1408 

1409 
 setup_lifting command: Sets up the Lifting package to work with a 

1410 
userdefined type. The user must provide either a quotient theorem 

1411 
or a type_definition theorem. The package configures transfer 

1412 
rules for equality and quantifiers on the type, and sets up the 

1413 
lift_definition command to work with the type. 

1414 

1415 
 Usage examples: See Quotient_Examples/Lift_DList.thy, 

47851  1416 
Quotient_Examples/Lift_RBT.thy, Quotient_Examples/Lift_FSet.thy, 
1417 
Word/Word.thy and Library/Float.thy. 

47809  1418 

1419 
* Quotient package: 

1420 

1421 
 The 'quotient_type' command now supports a 'morphisms' option with 

1422 
rep and abs functions, similar to typedef. 

1423 

1424 
 'quotient_type' sets up new types to work with the Lifting and 

1425 
Transfer packages, as with 'setup_lifting'. 

1426 

1427 
 The 'quotient_definition' command now requires the user to prove a
