* Experimental Prover IDE based on Isabelle/Scala and jEdit (see 
41612  427 
src/Tools/jEdit). This also serves as IDE for Isabelle/ML, with 
428 
useful tooltips and hyperlinks produced from its static analysis. The 

429 
bundled component provides an executable Isabelle tool that can be run 

430 
like this:

41595  437 
(and thus refers to something like $HOME/.isabelle/Isabelle2011), 
41594  438 
while the default heap location within that directory lacks that extra 
439 
suffix. This isolates multiple Isabelle installations from each

41571  597 
* Function package: f.psimps rules are no longer implicitly declared 
598 
as [simp]. INCOMPATIBILITY. 

41398  599 

600 
* Datatype package: theorems generated for executable equality (class 

41571  601 
"eq") carry proper names and are treated as default code equations. 
602 

41594  603 
* Inductive package: now offers command 'inductive_simps' to 
604 
automatically derive instantiated and simplified equations for 

605 
inductive predicates, similar to 'inductive_cases'. 

606 

41571  607 
* Command 'enriched_type' allows to register properties of the 
608 
functorial structure of types. 

39771  609 

39644  610 
* Improved infrastructure for term evaluation using code generator 
611 
techniques, in particular static evaluation conversions. 

612 

41594  613 
* Code generator: Scala (2.8 or higher) has been added to the target 
614 
languages. 

615 

41398  616 
* Code generator: globbing constant expressions "*" and "Theory.*" 
617 
have been replaced by the more idiomatic "_" and "Theory._". 

618 
INCOMPATIBILITY. 

619 

620 
* Code generator: export_code without explicit file declaration prints 

621 
to standard output. INCOMPATIBILITY. 

622 

623 
* Code generator: do not print function definitions for case 

624 
combinators any longer. 

625 

41594  626 
* Code generator: simplification with rules determined with 
41571  627 
src/Tools/Code/code_simp.ML and method "code_simp". 
628 

41594  629 
* Code generator for records: more idiomatic representation of record 
40948  630 
types. Warning: records are not covered by ancient SML code 
631 
generation any longer. INCOMPATIBILITY. In cases of need, a suitable 

632 
rep_datatype declaration helps to succeed then: 

38537  633 

634 
record 'a foo = ... 

635 
... 

636 
rep_datatype foo_ext ... 

38535  637 

41594  638 
* Records: logical foundation type for records does not carry a 
639 
'_type' suffix any longer (obsolete due to authentic syntax). 

640 
INCOMPATIBILITY. 

641 

41398  642 
* Quickcheck now by default uses exhaustive testing instead of random 
41571  643 
testing. Random testing can be invoked by "quickcheck [random]", 
644 
exhaustive testing by "quickcheck [exhaustive]". 

41398  645 

646 
* Quickcheck instantiates polymorphic types with small finite 

647 
datatypes by default. This enables a simple execution mechanism to 

648 
handle quantifiers and function equality over the finite datatypes. 

649 

41571  650 
* Quickcheck random generator has been renamed from "code" to 
651 
"random". INCOMPATIBILITY. 

41398  652 

653 
* Quickcheck now has a configurable time limit which is set to 30 

654 
seconds by default. This can be changed by adding [timeout = n] to the 

655 
quickcheck command. The time limit for Auto Quickcheck is still set 

656 
independently. 

38461  657 

658 
* Quickcheck in locales considers interpretations of that locale for 

659 
counter example search.

41571  692 
* Proof methods "metis" and "meson" now have configuration options 
693 
"meson_trace", "metis_trace", and "metis_verbose" that can be enabled 

694 
to diagnose these tools. E.g. 

695 

696 
using [[metis_trace = true]] 

697 

41398  698 
* Auto Solve: Renamed "Auto Solve Direct". The tool is now available 
699 
manually as command 'solve_direct'. 

700 

41601  701 
* The default SMT solver Z3 must be enabled explicitly (due to 
702 
licensing issues) by setting the environment variable 

41603  703 
Z3_NON_COMMERCIAL in etc/settings of the component, for example. For 
704 
commercial applications, the SMT solver CVC3 is provided as fallback; 

705 
changing the SMT solver is done via the configuration option 

706 
"smt_solver".

710 

711 
* Added basic SMT support for datatypes, records, and typedefs using 

712 
the oracle mode (no proofs). Direct support of pairs has been dropped 

713 
in exchange (pass theorems fst_conv snd_conv pair_collapse to the SMT

Various operations from the Haskell prelude are used for generating 

842

845 
"surj f" is now an abbreviation of "range f = UNIV". The theorems 

846 
bij_def and surj_def are unchanged. INCOMPATIBILITY.

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

41571  852 
"Sum_Type.Plus" instead. 
41398  853 

854 
* Constant "split" has been merged with constant "prod_case"; names of 

855 
ML functions, facts etc. involving split have been retained so far, 

856 
though. INCOMPATIBILITY. 

857 

858 
* Dropped old infix syntax "_ mem _" for List.member; use "_ : set _" 

859 
instead. INCOMPATIBILITY. 

860 

41571  861

863 

41594  864 
* Former theory Library/Enum is now part of the HOLMain image.

873 
Syntax in Library/State_Monad has been changed to avoid ambiguities. 

874 
INCOMPATIBILITY. 

875 

876 
* Theory Library/SetsAndFunctions has been split into 

877 
Library/Function_Algebras and Library/Set_Algebras; canonical names 

878 
for instance definitions for functions; various improvements. 

879 
INCOMPATIBILITY.

* Theory Library/Multiset provides stable quicksort implementation of 

882 
sort_key.

935 
* The domain package now runs in definitional mode by default: The 

41571  936 
former command 'new_domain' is now called 'domain'. To use the domain 
40621  937 
package in its original axiomatic mode, use 'domain (unsafe)'. 
938 
INCOMPATIBILITY. 

939 

41571  940 
* The new class "domain" is now the default sort. Class "predomain" 
941 
is an unpointed version of "domain". Theories can be updated by 

942 
replacing sort annotations as shown below. INCOMPATIBILITY. 

40621  943 

944 
'a::type ~> 'a::countable 

945 
'a::cpo ~> 'a::predomain 

946 
'a::pcpo ~> 'a::domain 

947 

41571  948 
* The old type class "rep" has been superseded by class "domain". 
40621  949 
Accordingly, users of the definitional package must remove any 
41571  950 
"default_sort rep" declarations. INCOMPATIBILITY. 
40621  951 

41401  952 
* The domain package (definitional mode) now supports unpointed 
953 
predomain argument types, as long as they are marked 'lazy'. (Strict 

41571  954 
arguments must be in class "domain".) For example, the following 
41401  955 
domain definition now works: 
956 

957 
domain natlist = nil  cons (lazy "nat discr") (lazy "natlist") 

958 

959 
* Theory HOLCF/Library/HOL_Cpo provides cpo and predomain class 

41571  960 
instances for types from main HOL: bool, nat, int, char, 'a + 'b, 
961 
'a option, and 'a list. Additionally, it configures fixrec and the 

962 
domain package to work with these types. For example: 

41401  963 

964 
fixrec isInl :: "('a + 'b) u > tr" 

965 
where "isInl$(up$(Inl x)) = TT"  "isInl$(up$(Inr y)) = FF" 

966 

967 
domain V = VFun (lazy "V > V")  VCon (lazy "nat") (lazy "V list") 

968 

41571  969 
* The "(permissive)" option of fixrec has been replaced with a 
970 
perequation "(unchecked)" option. See 

971 
src/HOL/HOLCF/Tutorial/Fixrec_ex.thy for examples. INCOMPATIBILITY. 

972 

973 
* The "bifinite" class no longer fixes a constant "approx"; the class 

974 
now just asserts that such a function exists. INCOMPATIBILITY. 

975 

976 
* Former type "alg_defl" has been renamed to "defl". HOLCF no longer

980 

981

987 
* The function "cprod_map" has been renamed to "prod_map". 

41401  988 
INCOMPATIBILITY. 
989 

990 
* The monadic bind operator on each powerdomain has new binder syntax 

41571  991 
similar to sets, e.g. "\<Union>\<sharp>x\<in>xs. t" represents 
992 
"upper_bind\<cdot>xs\<cdot>(\<Lambda> x. t)". 

41401  993 

994 
* The infix syntax for binary union on each powerdomain has changed 

41571  995 
from e.g. "+\<sharp>" to "\<union>\<sharp>", for consistency with set 
996 
syntax. INCOMPATIBILITY.

1027 
 With mutual recursion, "bisim" predicate is now curried.

*** General *** 
1186 

35436  1187 
* Authentic syntax for *all* logical entities (type classes, type 
1188 
constructors, term constants): provides simple and robust 

1189 
correspondence between formal entities and concrete syntax. Within 

1190 
the parse tree / AST representations, "constants" are decorated by 

1191 
their category (class, type, const) and spelled out explicitly with 

1192 
their full internal name. 

1193 

1194 
Substantial INCOMPATIBILITY concerning lowlevel syntax declarations 

1195 
and translations (translation rules and translation functions in ML). 

1196 
Some hints on upgrading: 

35260  1197 

1198 
 Many existing uses of 'syntax' and 'translations' can be replaced 

35436  1199 
by more modern 'type_notation', 'notation' and 'abbreviation', 
1200 
which are independent of this issue. 

35260  1201 

1202 
 'translations' require markup within the AST; the term syntax 

1203 
provides the following special forms: 

1204 

1205 
CONST c  produces syntax version of constant c from context 

35261  1206 
XCONST c  literally c, checked as constant from context 
1207 
c  literally c, if declared by 'syntax' 

1208 

1209 
Plain identifiers are treated as AST variables  occasionally the 

1210 
system indicates accidental variables via the error "rhs contains 

1211 
extra variables". 

35260  1212 

35436  1213 
Type classes and type constructors are marked according to their 
1214 
concrete syntax. Some old translations rules need to be written 

1215 
for the "type" category, using type constructor application 

1216 
instead of pseudoterm application of the default category 

1217 
"logic". 

1218 

35260  1219 
 'parse_translation' etc. in ML may use the following 
1220 
antiquotations: 

1221 

35436  1222 
@{class_syntax c}  type class c within parse tree / AST 
1223 
@{term_syntax c}  type constructor c within parse tree / AST 

35260  1224 
@{const_syntax c}  ML version of "CONST c" above 
1225 
@{syntax_const c}  literally c (checked wrt. 'syntax' declarations) 

1226 

35436  1227 
 Literal types within 'typed_print_translations', i.e. those *not* 
1228 
represented as pseudoterms are represented verbatim. Use @{class 

1229 
c} or @{type_name c} here instead of the above syntax 

1230 
antiquotations. 

1231 

35260  1232 
Note that old nonauthentic syntax was based on unqualified base 
35436  1233 
names, so all of the above "constant" names would coincide. Recall 
1234 
that 'print_syntax' and ML_command "set Syntax.trace_ast" help to 

1235 
diagnose syntax problems.

1337 
* New package for quotient types. Commands 'quotient_type' and 

1338 
'quotient_definition' may be used for defining types and constants by 

1339 
quotient constructions. An example is the type of integers created by 

1340 
quotienting pairs of natural numbers: 

37380  1341 

37351  1342 
fun 
37380  1343 
intrel :: "(nat * nat) => (nat * nat) => bool" 
37351  1344 
where 
1345 
"intrel (x, y) (u, v) = (x + v = u + y)" 

1346 

37380  1347 
quotient_type int = "nat * nat" / intrel

37380  1349 

37351  1350 
quotient_definition 
1351 
"0::int" is "(0::nat, 0::nat)" 

1352 

1353 
The method "lifting" can be used to lift of theorems from the 

1354 
underlying "raw" type to the quotient type. The example 

1355 
src/HOL/Quotient_Examples/FSet.thy includes such a quotient 

1356 
construction and provides a reasoning infrastructure for finite sets. 

1357
