*** HOL *** 
20 

31547  21 
* Class semiring_div requires superclass no_zero_divisors and proof of 
22 
div_mult_mult1; theorems div_mult_mult1, div_mult_mult2, 

23 
div_mult_mult1_if, div_mult_mult1 and div_mult_mult2 have been 

24 
generalized to class semiring_div, subsuming former theorems 

25 
zdiv_zmult_zmult1, zdiv_zmult_zmult1_if, zdiv_zmult_zmult1 and 

26 
zdiv_zmult_zmult2. div_mult_mult1 is now [simp] by default. 

27 
INCOMPATIBILITY. 

28 

29 
* Power operations on relations and functions are now one dedicate 

30 
constant compow with infix syntax "^^". Power operations on 

31 
multiplicative monoids retains syntax "^" and is now defined generic 

32 
in class power. INCOMPATIBILITY. 

33 

34 
* ML antiquotation @{code_datatype} inserts definition of a datatype 

35 
generated by the code generator; see Predicate.thy for an example. 

36 

37 
* New method "linarith" invokes existing linear arithmetic decision 

38 
procedure only. 

31481  39 

31900  40 
* Implementation of quickcheck using generic code generator; default 
41 
generators are provided for all suitable HOL types, records and 

42 
datatypes. 

43 

44 
* Constants Set.Pow and Set.image now with authentic syntax; 

45 
objectlogic definitions Set.Pow_def and Set.image_def. 

46 
INCOMPATIBILITY. 

31643  47 

31790  48 
* Renamed theorems: 
49 
Suc_eq_add_numeral_1 > Suc_eq_plus1 

50 
Suc_eq_add_numeral_1_left > Suc_eq_plus1_left 

51 
Suc_plus1 > Suc_eq_plus1 

52 

31814  53 
* New sledgehammer option "Full Types" in Proof General settings menu. 
31900  54 
Causes full type information to be output to the ATPs. This slows 
55 
ATPs down considerably but eliminates a source of unsound "proofs" 

56 
that fail later. 

57 

58 
* Discontinued ancient tradition to suffix certain ML module names 

59 
with "_package", e.g.:

* NewNumberTheory: Jeremy Avigad's new version of part of 
69 
NumberTheory. If possible, use NewNumberTheory, not NumberTheory. 

30949  70 

31784  71 
* Simplified interfaces of datatype module. INCOMPATIBILITY. 
72 

31900  73 
* Abbreviation "arbitrary" of "undefined" has disappeared; use 
74 
"undefined" directly. INCOMPATIBILITY. 

75 

76 
* New evaluator "approximate" approximates an real valued term using 

77 
the same method as the approximation method. 

78 

79 
* Method "approximate" supports now arithmetic expressions as 

80 
boundaries of intervals and implements interval splitting and Taylor 

81 
series expansion. 

82 

31901  83 
* Changed DERIV_intros to a dynamic fact (via Named_Thms). Each of 
31900  84 
the theorems in DERIV_intros assumes composition with an additional 
85 
function and matches a variable to the derivative, which has to be 

86 
solved by the simplifier. Hence (auto intro!: DERIV_intros) computes 

87 
the derivative of most elementary terms. 

88 

89 
* Maclauren.DERIV_tac and Maclauren.deriv_tac was removed, they are 

90 
replaced by: (auto intro!: DERIV_intros). INCOMPATIBILITY.

Tutorial on Locales ("locales" manual) for details. 
29253  171 

172 
 In locale expressions, instantiation replaces renaming. Parameters 

173 
must be declared in a for clause. To aid compatibility with previous 

174 
parameter inheritance, in locale declarations, parameters that are not 

175 
'touched' (instantiation position "_" or omitted) are implicitly added 

176 
with their syntax at the beginning of the for clause. 

177 

178 
 Syntax from abbreviations and definitions in locales is available in 

179 
locale expressions and context elements. The latter is particularly 

180 
useful in locale declarations. 

181

 More flexible mechanisms to qualify names generated by locale

expressions. Qualifiers (prefixes) may be specified in locale

* Nominal datatypes can now contain typevariables. 
728 

729 
* Commands 'nominal_inductive' and 'equivariance' work with local 

730 
theory targets. 

731 

732 
* Nominal primrec can now works with local theory targets and its 

733 
specification syntax now conforms to the general format as seen in 

734 
'inductive' etc. 

735 

736 
* Method "perm_simp" honours the standard simplifier attributes 

737 
(no_asm), (no_asm_use) etc. 

738 

739 
* The new predicate #* is defined like freshness, except that on the 

740 
left hand side can be a set or list of atoms. 

741 

742 
* Experimental command 'nominal_inductive2' derives strong induction 

743 
principles for inductive definitions. In contrast to 

744 
'nominal_inductive', which can only deal with a fixed number of 

745 
binders, it can deal with arbitrary expressions standing for sets of 

746 
atoms to be avoided. The only inductive definition we have at the 

747 
moment that needs this generalisation is the typing rule for Lets in 

748 
the algorithm W: 

749 

750 
Gamma  t1 : T1 (x,close Gamma T1)::Gamma  t2 : T2 x#Gamma 

751 
 

752 
Gamma  Let x be t1 in t2 : T2 

753 

754 
In this rule one wants to avoid all the binders that are introduced by 

755 
"close Gamma T1". We are looking for other examples where this 

756 
feature might be useful. Please let us know.

935

943 

26681  944 
* Unused theorems can be found using the new command 'unused_thms'. 
945 
There are three ways of invoking it: 

946 

947 
(1) unused_thms 

948 
Only finds unused theorems in the current theory. 

949 

950 
(2) unused_thms thy_1 ... thy_n  

951 
Finds unused theorems in the current theory and all of its ancestors, 

952 
excluding the theories thy_1 ... thy_n and all of their ancestors. 

953 

954 
(3) unused_thms thy_1 ... thy_n  thy'_1 ... thy'_m 

955 
Finds unused theorems in the theories thy'_1 ... thy'_m and all of 

956 
their ancestors, excluding the theories thy_1 ... thy_n and all of 

957 
their ancestors. 

958 

26718  959 
In order to increase the readability of the list produced by 
960 
unused_thms, theorems that have been created by a particular instance 

26874  961 
of a theory command such as 'inductive' or 'function' are considered 
962 
to belong to the same "group", meaning that if at least one theorem in 

26718  963 
this group is used, the other theorems in the same group are no longer 
964 
reported as unused. Moreover, if all theorems in the group are 

965 
unused, only one theorem in the group is displayed. 

966 

967 
Note that proof objects have to be switched on in order for 

968 
unused_thms to work properly (i.e. !proofs must be >= 1, which is 

26874  969 
usually the case when using Proof General with the default settings). 
26681  970 

26650  971 
* Authentic naming of facts disallows adhoc overwriting of previous 
972 
theorems within the same name space. INCOMPATIBILITY, need to remove 

973 
duplicate fact bindings, or even accidental fact duplications. Note 

974 
that tools may maintain dynamically scoped facts systematically, using 

975 
PureThy.add_thms_dynamic. 

976 

26660  977 
* Command 'hide' now allows to hide from "fact" name space as well.

* Method "induct_scheme" derives userspecified induction rules

from wellfounded induction and completeness of patterns. This factors 
1056

* More flexible generation of measure functions for termination 

1061 
proofs: Measure functions can be declared by proving a rule of the 

1062 
form "is_measure f" and giving it the [measure_function] attribute. 

1063 
The "is_measure" predicate is logically meaningless (always true), and 

1064 
just guides the heuristic. To find suitable measure functions, the 

1065 
termination prover sets up the goal "is_measure ?f" of the appropriate 

1066 
type and generates all solutions by prologstyle backwards proof using 

1067 
the declared rules. 

1068 

1069 
This setup also deals with rules like 

1070 

1071 
"is_measure f ==> is_measure (list_size f)" 

1072 

1073 
which accommodates nested datatypes that recurse through lists. 

1074 
Similar rules are predeclared for products and option types.
