8 

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

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.

* Command 'partial_function' provides basic support for recursive 
623 
function definitions over complete partial orders. Concrete instances 

40183  624 
are provided for i) the option type, ii) tail recursion on arbitrary 
41571  625 
types, and iii) the heap monad of Imperative_HOL. See 
626 
src/HOL/ex/Fundefs.thy and src/HOL/Imperative_HOL/ex/Linked_Lists.thy 

627 
for examples. 

40183  628

* Function package: f.psimps rules are no longer implicitly declared 
630 
as [simp]. INCOMPATIBILITY. 

41398  631 

632 
* Datatype package: theorems generated for executable equality (class 

41571  633 
"eq") carry proper names and are treated as default code equations. 
634 

41594  635 
* Inductive package: now offers command 'inductive_simps' to 
636 
automatically derive instantiated and simplified equations for 

637 
inductive predicates, similar to 'inductive_cases'. 

638 

41571  639 
* Command 'enriched_type' allows to register properties of the 
640 
functorial structure of types. 

39771  641 

39644  642 
* Improved infrastructure for term evaluation using code generator 
643 
techniques, in particular static evaluation conversions. 

644 

41594  645 
* Code generator: Scala (2.8 or higher) has been added to the target 
646 
languages. 

647 

41398  648 
* Code generator: globbing constant expressions "*" and "Theory.*" 
649 
have been replaced by the more idiomatic "_" and "Theory._". 

650 
INCOMPATIBILITY. 

651 

652 
* Code generator: export_code without explicit file declaration prints 

653 
to standard output. INCOMPATIBILITY.

655 
* Code generator: do not print function definitions for case 

656 
combinators any longer. 

657 

41594  658 
* Code generator: simplification with rules determined with 
41571  659 
src/Tools/Code/code_simp.ML and method "code_simp". 
660 

41594  661 
* Code generator for records: more idiomatic representation of record 
40948  662 
types. Warning: records are not covered by ancient SML code 
663 
generation any longer. INCOMPATIBILITY. In cases of need, a suitable 

664 
rep_datatype declaration helps to succeed then: 

38537  665 

666 
record 'a foo = ... 

667 
... 

668 
rep_datatype foo_ext ... 

38535  669

* Records: logical foundation type for records does not carry a 
671 
'_type' suffix any longer (obsolete due to authentic syntax).

INCOMPATIBILITY. 

673

* Quickcheck now by default uses exhaustive testing instead of random 
41571  675 
testing. Random testing can be invoked by "quickcheck [random]", 
676 
exhaustive testing by "quickcheck [exhaustive]". 

41398  677 

678 
* Quickcheck instantiates polymorphic types with small finite 

679 
datatypes by default. This enables a simple execution mechanism to 

680 
handle quantifiers and function equality over the finite datatypes. 

681 

41571  682 
* Quickcheck random generator has been renamed from "code" to 
683 
"random". INCOMPATIBILITY. 

41398  684 

685 
* Quickcheck now has a configurable time limit which is set to 30 

686 
seconds by default. This can be changed by adding [timeout = n] to the 

687 
quickcheck command. The time limit for Auto Quickcheck is still set 

688 
independently. 

38461  689 

690 
* Quickcheck in locales considers interpretations of that locale for 

691 
counter example search.

731 
manually as command 'solve_direct'. 

732 

41601  733

734 
licensing issues) by setting the environment variable 

41603  735 
Z3_NON_COMMERCIAL in etc/settings of the component, for example. For 
736

967 
* The domain package now runs in definitional mode by default: The 

41571  968 
former command 'new_domain' is now called 'domain'. To use the domain 
40621  969 
package in its original axiomatic mode, use 'domain (unsafe)'. 
970 
INCOMPATIBILITY. 

971 

41571  972 
* The new class "domain" is now the default sort. Class "predomain" 
973 
is an unpointed version of "domain". Theories can be updated by 

974 
replacing sort annotations as shown below. INCOMPATIBILITY. 

40621  975 

976 
'a::type ~> 'a::countable

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

978 
'a::pcpo ~> 'a::domain 

979 

41571  980 
* The old type class "rep" has been superseded by class "domain". 
40621  981 
Accordingly, users of the definitional package must remove any 
41571  982 
"default_sort rep" declarations. INCOMPATIBILITY. 
40621  983 

41401  984 
* The domain package (definitional mode) now supports unpointed 
985 
predomain argument types, as long as they are marked 'lazy'. (Strict 

41571  986 
arguments must be in class "domain".) For example, the following 
41401  987 
domain definition now works: 
988 

989 
domain natlist = nil  cons (lazy "nat discr") (lazy "natlist") 

990 

991 
* Theory HOLCF/Library/HOL_Cpo provides cpo and predomain class 

41571  992 
instances for types from main HOL: bool, nat, int, char, 'a + 'b, 
993 
'a option, and 'a list. Additionally, it configures fixrec and the 

994 
domain package to work with these types. For example: 

41401  995 

996 
fixrec isInl :: "('a + 'b) u > tr" 

997 
where "isInl$(up$(Inl x)) = TT"  "isInl$(up$(Inr y)) = FF" 

998 

999 
domain V = VFun (lazy "V > V")  VCon (lazy "nat") (lazy "V list") 

1000 

41571  1001 
* The "(permissive)" option of fixrec has been replaced with a 
1002 
perequation "(unchecked)" option. See 

1003 
src/HOL/HOLCF/Tutorial/Fixrec_ex.thy for examples. INCOMPATIBILITY. 

1004 

1005 
* The "bifinite" class no longer fixes a constant "approx"; the class 

1006 
now just asserts that such a function exists. INCOMPATIBILITY. 

1007 

1008 
* Former type "alg_defl" has been renamed to "defl". HOLCF no longer

1012 

1013

1014 

1015 
* The predicate "directed" has been removed. INCOMPATIBILITY. 

1016 

1017 
* The type class "finite_po" has been removed. INCOMPATIBILITY. 

1018 

1019 
* The function "cprod_map" has been renamed to "prod_map". 

41401  1020 
INCOMPATIBILITY. 
1021 

1022 
* The monadic bind operator on each powerdomain has new binder syntax 

41571  1023 
similar to sets, e.g. "\<Union>\<sharp>x\<in>xs. t" represents 
1024 
"upper_bind\<cdot>xs\<cdot>(\<Lambda> x. t)". 

41401  1025 

1026 
* The infix syntax for binary union on each powerdomain has changed 

41571  1027 
from e.g. "+\<sharp>" to "\<union>\<sharp>", for consistency with set 
1028 
syntax. INCOMPATIBILITY.

41571  1057 

1058 
 Definitions of "bisim" constants no longer mention definedness. 

1059 
 With mutual recursion, "bisim" predicate is now curried.

*** General *** 
1218 

35436  1219 
* Authentic syntax for *all* logical entities (type classes, type 
1220 
constructors, term constants): provides simple and robust 

1221 
correspondence between formal entities and concrete syntax. Within 

1222 
the parse tree / AST representations, "constants" are decorated by 

1223 
their category (class, type, const) and spelled out explicitly with 

1224 
their full internal name. 

1225 

1226 
Substantial INCOMPATIBILITY concerning lowlevel syntax declarations 

1227 
and translations (translation rules and translation functions in ML). 

1228 
Some hints on upgrading: 

35260  1229 

1230 
 Many existing uses of 'syntax' and 'translations' can be replaced 

35436  1231 
by more modern 'type_notation', 'notation' and 'abbreviation', 
1232 
which are independent of this issue. 

35260  1233 

1234 
 'translations' require markup within the AST; the term syntax 

1235 
provides the following special forms: 

1236 

1237 
CONST c  produces syntax version of constant c from context 

35261  1238 
XCONST c  literally c, checked as constant from context 
1239 
c  literally c, if declared by 'syntax' 

1240 

1241 
Plain identifiers are treated as AST variables  occasionally the 

1242 
system indicates accidental variables via the error "rhs contains 

1243 
extra variables". 

35260  1244 

35436  1245 
Type classes and type constructors are marked according to their 
1246 
concrete syntax. Some old translations rules need to be written 

1247 
for the "type" category, using type constructor application 

1248 
instead of pseudoterm application of the default category 

1249 
"logic". 

1250 

35260  1251 
 'parse_translation' etc. in ML may use the following 
1252 
antiquotations: 

1253 

35436  1254 
@{class_syntax c}  type class c within parse tree / AST 
1255 
@{term_syntax c}  type constructor c within parse tree / AST 

35260  1256 
@{const_syntax c}  ML version of "CONST c" above 
1257 
@{syntax_const c}  literally c (checked wrt. 'syntax' declarations) 

1258 

35436  1259 
 Literal types within 'typed_print_translations', i.e. those *not* 
1260 
represented as pseudoterms are represented verbatim. Use @{class 

1261 
c} or @{type_name c} here instead of the above syntax 

1262 
antiquotations. 

1263 

35260  1264 
Note that old nonauthentic syntax was based on unqualified base 
35436  1265 
names, so all of the above "constant" names would coincide. Recall 
1266 
that 'print_syntax' and ML_command "set Syntax.trace_ast" help to 

1267 
diagnose syntax problems.

* New package for quotient types. Commands 'quotient_type' and 

1370 
'quotient_definition' may be used for defining types and constants by

quotient_definition 
1383 
"0::int" is "(0::nat, 0::nat)" 

1384 

1385 
The method "lifting" can be used to lift of theorems from the 

1386 
underlying "raw" type to the quotient type. The example 

1387 
src/HOL/Quotient_Examples/FSet.thy includes such a quotient 

1388 
construction and provides a reasoning infrastructure for finite sets.
