* 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.

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.

Tutorial on Locales ("locales" manual) for details. 
29253  113 

114 
 In locale expressions, instantiation replaces renaming. Parameters 

115 
must be declared in a for clause. To aid compatibility with previous 

116 
parameter inheritance, in locale declarations, parameters that are not 

117 
'touched' (instantiation position "_" or omitted) are implicitly added 

118 
with their syntax at the beginning of the for clause. 

119 

120 
 Syntax from abbreviations and definitions in locales is available in 

121 
locale expressions and context elements. The latter is particularly 

122 
useful in locale declarations. 

123 

124 
 More flexible mechanisms to qualify names generated by locale 

125 
expressions. Qualifiers (prefixes) may be specified in locale

697 
"close Gamma T1". We are looking for other examples where this 

698

* Name space merge now observes canonical order, i.e. the second space

885 

26681  886 
* Unused theorems can be found using the new command 'unused_thms'. 
887 
There are three ways of invoking it: 

888 

889 
(1) unused_thms 

890 
Only finds unused theorems in the current theory. 

891 

892 
(2) unused_thms thy_1 ... thy_n  

893 
Finds unused theorems in the current theory and all of its ancestors, 

894 
excluding the theories thy_1 ... thy_n and all of their ancestors. 

895 

896 
(3) unused_thms thy_1 ... thy_n  thy'_1 ... thy'_m 

897 
Finds unused theorems in the theories thy'_1 ... thy'_m and all of 

898 
their ancestors, excluding the theories thy_1 ... thy_n and all of 

899 
their ancestors. 

900 

26718  901 
In order to increase the readability of the list produced by 
902 
unused_thms, theorems that have been created by a particular instance 

26874  903 
of a theory command such as 'inductive' or 'function' are considered 
904 
to belong to the same "group", meaning that if at least one theorem in 

26718  905 
this group is used, the other theorems in the same group are no longer 
906 
reported as unused. Moreover, if all theorems in the group are 

907 
unused, only one theorem in the group is displayed. 

908 

909 
Note that proof objects have to be switched on in order for 

910 
unused_thms to work properly (i.e. !proofs must be >= 1, which is 

26874  911 
usually the case when using Proof General with the default settings). 
26681  912 

26650  913 
* Authentic naming of facts disallows adhoc overwriting of previous 
914 
theorems within the same name space. INCOMPATIBILITY, need to remove 

915 
duplicate fact bindings, or even accidental fact duplications. Note 

916 
that tools may maintain dynamically scoped facts systematically, using 

917 
PureThy.add_thms_dynamic. 

918 

26660  919 
* Command 'hide' now allows to hide from "fact" name space as well.

* Method "induct_scheme" derives userspecified induction rules 
27067  997 
from wellfounded induction and completeness of patterns. This factors 
998

* More flexible generation of measure functions for termination 

1003 
proofs: Measure functions can be declared by proving a rule of the 

1004 
form "is_measure f" and giving it the [measure_function] attribute. 

1005 
The "is_measure" predicate is logically meaningless (always true), and 

1006 
just guides the heuristic. To find suitable measure functions, the 

1007 
termination prover sets up the goal "is_measure ?f" of the appropriate 

1008 
type and generates all solutions by prologstyle backwards proof using 

1009 
the declared rules. 

1010 

1011 
This setup also deals with rules like 

1012 

1013 
"is_measure f ==> is_measure (list_size f)" 

1014 

1015 
which accommodates nested datatypes that recurse through lists. 

1016 
Similar rules are predeclared for products and option types.

theorems within a class context produce both relative results (with 

1380 
implicit parameters according to the locale context), and polymorphic 

1381 
constants with qualified polymorphism (according to the class 

1382 
context). Within the body context of a 'class' target, a separate 

1383 
syntax layer ("user space type system") takes care of converting 

1384 
between global polymorphic consts and internal locale representation.
