41571  490 
* Command 'enriched_type' allows to register properties of the 
491 
functorial structure of types. 

39771  492 

39644  493 
* Improved infrastructure for term evaluation using code generator 
494 
techniques, in particular static evaluation conversions. 

495 

41594  496 
* Code generator: Scala (2.8 or higher) has been added to the target 
497 
languages. 

498 

41398  499 
* Code generator: globbing constant expressions "*" and "Theory.*" 
500 
have been replaced by the more idiomatic "_" and "Theory._". 

501 
INCOMPATIBILITY. 

502 

503 
* Code generator: export_code without explicit file declaration prints 

504 
to standard output. INCOMPATIBILITY. 

505 

506 
* Code generator: do not print function definitions for case 

507 
combinators any longer. 

508 

41594  509 
* Code generator: simplification with rules determined with 
41571  510 
src/Tools/Code/code_simp.ML and method "code_simp". 
511 

41594  512 
* Code generator for records: more idiomatic representation of record 
40948  513 
types. Warning: records are not covered by ancient SML code 
514 
generation any longer. INCOMPATIBILITY. In cases of need, a suitable 

515 
rep_datatype declaration helps to succeed then: 

38537  516 

517 
record 'a foo = ... 

518 
... 

519 
rep_datatype foo_ext ... 

38535  520 

41594  521 
* Records: logical foundation type for records does not carry a 
522 
'_type' suffix any longer (obsolete due to authentic syntax). 

523 
INCOMPATIBILITY. 

524 

41398  525 
* Quickcheck now by default uses exhaustive testing instead of random 
41571  526 
testing. Random testing can be invoked by "quickcheck [random]", 
527 
exhaustive testing by "quickcheck [exhaustive]". 

41398  528 

529 
* Quickcheck instantiates polymorphic types with small finite 

530 
datatypes by default. This enables a simple execution mechanism to 

531 
handle quantifiers and function equality over the finite datatypes. 

532 

41571  533 
* Quickcheck random generator has been renamed from "code" to 
534 
"random". INCOMPATIBILITY. 

41398  535 

536 
* Quickcheck now has a configurable time limit which is set to 30 

537 
seconds by default. This can be changed by adding [timeout = n] to the 

538 
quickcheck command. The time limit for Auto Quickcheck is still set 

539 
independently. 

38461  540 

541 
* Quickcheck in locales considers interpretations of that locale for 

542 
counter example search.

41571  575 
* Proof methods "metis" and "meson" now have configuration options 
576 
"meson_trace", "metis_trace", and "metis_verbose" that can be enabled 

577 
to diagnose these tools. E.g. 

578 

579 
using [[metis_trace = true]] 

580 

41398  581 
* Auto Solve: Renamed "Auto Solve Direct". The tool is now available 
582 
manually as command 'solve_direct'. 

583 

41601  584 
* The default SMT solver Z3 must be enabled explicitly (due to 
585 
licensing issues) by setting the environment variable 

41603  586 
Z3_NON_COMMERCIAL in etc/settings of the component, for example. For 
587 
commercial applications, the SMT solver CVC3 is provided as fallback; 

588 
changing the SMT solver is done via the configuration option 

589 
"smt_solver".

593 

594 
* Added basic SMT support for datatypes, records, and typedefs using 

595 
the oracle mode (no proofs). Direct support of pairs has been dropped 

596 
in exchange (pass theorems fst_conv snd_conv pair_collapse to the SMT

729 
bij_def and surj_def are unchanged. INCOMPATIBILITY.

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

41571  735 
"Sum_Type.Plus" instead. 
41398  736 

737 
* Constant "split" has been merged with constant "prod_case"; names of 

738 
ML functions, facts etc. involving split have been retained so far, 

739 
though. INCOMPATIBILITY. 

740

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

742

746 

41594  747

INCOMPATIBILITY. 

758 

759

773 

774

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

786

*** HOLCF *** 
817 

818 
* The domain package now runs in definitional mode by default: The 

41571  819 
former command 'new_domain' is now called 'domain'. To use the domain 
40621  820 
package in its original axiomatic mode, use 'domain (unsafe)'. 
821 
INCOMPATIBILITY. 

822 

41571  823 
* The new class "domain" is now the default sort. Class "predomain" 
824 
is an unpointed version of "domain". Theories can be updated by 

825 
replacing sort annotations as shown below. INCOMPATIBILITY. 

40621  826 

827 
'a::type ~> 'a::countable 

828 
'a::cpo ~> 'a::predomain 

829 
'a::pcpo ~> 'a::domain 

830 

41571  831 
* The old type class "rep" has been superseded by class "domain". 
40621  832 
Accordingly, users of the definitional package must remove any 
41571  833 
"default_sort rep" declarations. INCOMPATIBILITY. 
40621  834 

41401  835 
* The domain package (definitional mode) now supports unpointed 
836 
predomain argument types, as long as they are marked 'lazy'. (Strict 

41571  837 
arguments must be in class "domain".) For example, the following 
41401  838 
domain definition now works: 
839 

840 
domain natlist = nil  cons (lazy "nat discr") (lazy "natlist") 

841 

842 
* Theory HOLCF/Library/HOL_Cpo provides cpo and predomain class 

41571  843 
instances for types from main HOL: bool, nat, int, char, 'a + 'b, 
844 
'a option, and 'a list. Additionally, it configures fixrec and the 

845 
domain package to work with these types. For example: 

41401  846 

847 
fixrec isInl :: "('a + 'b) u > tr" 

848 
where "isInl$(up$(Inl x)) = TT"  "isInl$(up$(Inr y)) = FF" 

849 

850 
domain V = VFun (lazy "V > V")  VCon (lazy "nat") (lazy "V list") 

851 

41571  852 
* The "(permissive)" option of fixrec has been replaced with a 
853 
perequation "(unchecked)" option. See 

854 
src/HOL/HOLCF/Tutorial/Fixrec_ex.thy for examples. INCOMPATIBILITY. 

855 

856 
* The "bifinite" class no longer fixes a constant "approx"; the class 

857 
now just asserts that such a function exists. INCOMPATIBILITY. 

858 

859 
* Former type "alg_defl" has been renamed to "defl". HOLCF no longer

863 

864

868 
* The type class "finite_po" has been removed. INCOMPATIBILITY. 

869 

870 
* The function "cprod_map" has been renamed to "prod_map". 

41401  871 
INCOMPATIBILITY. 
872 

873 
* The monadic bind operator on each powerdomain has new binder syntax 

41571  874 
similar to sets, e.g. "\<Union>\<sharp>x\<in>xs. t" represents 
875 
"upper_bind\<cdot>xs\<cdot>(\<Lambda> x. t)". 

41401  876 

877 
* The infix syntax for binary union on each powerdomain has changed 

41571  878 
from e.g. "+\<sharp>" to "\<union>\<sharp>", for consistency with set 
879 
syntax. INCOMPATIBILITY.

907

41571  908 

909 
 Definitions of "bisim" constants no longer mention definedness. 

910 
 With mutual recursion, "bisim" predicate is now curried.

35436  1070 
* Authentic syntax for *all* logical entities (type classes, type 
1071 
constructors, term constants): provides simple and robust 

1072 
correspondence between formal entities and concrete syntax. Within 

1073 
the parse tree / AST representations, "constants" are decorated by 

1074 
their category (class, type, const) and spelled out explicitly with 

1075 
their full internal name. 

1076 

1077 
Substantial INCOMPATIBILITY concerning lowlevel syntax declarations 

1078 
and translations (translation rules and translation functions in ML). 

1079 
Some hints on upgrading: 

35260  1080 

1081 
 Many existing uses of 'syntax' and 'translations' can be replaced 

35436  1082 
by more modern 'type_notation', 'notation' and 'abbreviation', 
1083 
which are independent of this issue. 

35260  1084 

1085 
 'translations' require markup within the AST; the term syntax 

1086 
provides the following special forms: 

1087 

1088 
CONST c  produces syntax version of constant c from context 

35261  1089 
XCONST c  literally c, checked as constant from context 
1090 
c  literally c, if declared by 'syntax' 

1091 

1092 
Plain identifiers are treated as AST variables  occasionally the 

1093 
system indicates accidental variables via the error "rhs contains 

1094 
extra variables". 

35260  1095 

35436  1096 
Type classes and type constructors are marked according to their 
1097 
concrete syntax. Some old translations rules need to be written 

1098 
for the "type" category, using type constructor application 

1099 
instead of pseudoterm application of the default category 

1100 
"logic". 

1101 

35260  1102 
 'parse_translation' etc. in ML may use the following 
1103 
antiquotations: 

1104 

35436  1105 
@{class_syntax c}  type class c within parse tree / AST 
1106 
@{term_syntax c}  type constructor c within parse tree / AST 

35260  1107 
@{const_syntax c}  ML version of "CONST c" above 
1108 
@{syntax_const c}  literally c (checked wrt. 'syntax' declarations) 

1109 

35436  1110 
 Literal types within 'typed_print_translations', i.e. those *not* 
1111 
represented as pseudoterms are represented verbatim. Use @{class 

1112 
c} or @{type_name c} here instead of the above syntax 

1113 
antiquotations. 

1114 

35260  1115 
Note that old nonauthentic syntax was based on unqualified base 
35436  1116 
names, so all of the above "constant" names would coincide. Recall 
1117 
that 'print_syntax' and ML_command "set Syntax.trace_ast" help to 

1118 
diagnose syntax problems.

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

1221 
'quotient_definition' may be used for defining types and constants by 

1222

1223 
quotienting pairs of natural numbers:

37351  1225 
fun 
37380  1226 
intrel :: "(nat * nat) => (nat * nat) => bool"

where

"intrel (x, y) (u, v) = (x + v = u + y)"

quotient_type int = "nat * nat" / intrel

quotient_definition 
1234 
"0::int" is "(0::nat, 0::nat)" 

1235 

1236 
The method "lifting" can be used to lift of theorems from the 

1237 
underlying "raw" type to the quotient type. The example 

1238 
src/HOL/Quotient_Examples/FSet.thy includes such a quotient 

1239 
construction and provides a reasoning infrastructure for finite sets. 

1240
