* Different bookkeeping for code equations:

a) On theory merge, the last set of code equations for a particular constant 

110 
is taken (in accordance with the policy applied by other parts of the 

111 
code generator framework). 

112 
b) Code equations stemming from explicit declarations (e.g. code attribute) 

113 
gain priority over default code equations stemming from definition, primrec, 

114 
fun etc.

* Dropped locale element "includes". This is a major INCOMPATIBILITY. 
121 
In existing theorem specifications replace the includes element by the 

122 
respective context elements of the included locale, omitting those that 

123 
are already present in the theorem specification. Multiple assume 

124 
elements of a locale should be replaced by a single one involving the 

125 
locale predicate. In the proof body, declarations (most notably 

126 
theorems) may be regained by interpreting the respective locales in the 

127 
proof context as required (command "interpret"). 

128 
If using "includes" in replacement of a target solely because the 

129 
parameter types in the theorem are not as general as in the target, 

130 
consider declaring a new locale with additional type constraints on the 

131 
parameters (context element "constrains"). 

132

29253  142 
* Complete reimplementation of locales. INCOMPATIBILITY. 
143 
The most important changes are listed below. See documentation 

144 
(forthcoming) and tutorial (also forthcoming) for details. 

145 

146 
 In locale expressions, instantiation replaces renaming. Parameters 

147 
must be declared in a for clause. To aid compatibility with previous 

148 
parameter inheritance, in locale declarations, parameters that are not 

149 
'touched' (instantiation position "_" or omitted) are implicitly added 

150 
with their syntax at the beginning of the for clause. 

151 

152 
 Syntax from abbreviations and definitions in locales is available in 

153 
locale expressions and context elements. The latter is particularly 

154 
useful in locale declarations. 

155 

156 
 More flexible mechanisms to qualify names generated by locale 

157 
expressions. Qualifiers (prefixes) may be specified in locale 

158 
expressions. Available are normal qualifiers (syntax "name:") and strict 

159 
qualifiers (syntax "name!:"). The latter must occur in name references 

160 
and are useful to avoid accidental hiding of names, the former are 

161 
optional. Qualifiers derived from the parameter names of a locale are no 

162 
longer generated. 

163 

164 
 "sublocale l < e" replaces "interpretation l < e". The instantiation 

165 
clause in "interpretation" and "interpret" (square brackets) is no 

166 
longer available. Use locale expressions. 

167 

168 
 When converting proof scripts, be sure to replace qualifiers in 

169 
"interpretation" and "interpret" by strict qualifiers. Qualifiers in 

170 
locale expressions range over a single locale instance only.

* The Isabelle "emacs" tool provides a specific interface to invoke 
514 
Proof General / Emacs, with more explicit failure if that is not 

515 
installed (the old isabelleinterface script silently falls back on

571 

26681  572 
* Unused theorems can be found using the new command 'unused_thms'. 
573 
There are three ways of invoking it: 

574 

575 
(1) unused_thms 

576 
Only finds unused theorems in the current theory. 

577 

578 
(2) unused_thms thy_1 ... thy_n  

579 
Finds unused theorems in the current theory and all of its ancestors, 

580 
excluding the theories thy_1 ... thy_n and all of their ancestors. 

581 

582 
(3) unused_thms thy_1 ... thy_n  thy'_1 ... thy'_m 

583 
Finds unused theorems in the theories thy'_1 ... thy'_m and all of 

584 
their ancestors, excluding the theories thy_1 ... thy_n and all of 

585 
their ancestors. 

586 

26718  587 
In order to increase the readability of the list produced by 
588 
unused_thms, theorems that have been created by a particular instance 

26874  589 
of a theory command such as 'inductive' or 'function' are considered 
590 
to belong to the same "group", meaning that if at least one theorem in 

26718  591 
this group is used, the other theorems in the same group are no longer 
592 
reported as unused. Moreover, if all theorems in the group are 

593 
unused, only one theorem in the group is displayed. 

594 

595 
Note that proof objects have to be switched on in order for 

596 
unused_thms to work properly (i.e. !proofs must be >= 1, which is 

26874  597 
usually the case when using Proof General with the default settings). 
26681  598 

26650  599 
* Authentic naming of facts disallows adhoc overwriting of previous 
600 
theorems within the same name space. INCOMPATIBILITY, need to remove 

601 
duplicate fact bindings, or even accidental fact duplications. Note 

602 
that tools may maintain dynamically scoped facts systematically, using 

603 
PureThy.add_thms_dynamic. 

604 

26660  605 
* Command 'hide' now allows to hide from "fact" name space as well.

* Method "induct_scheme" derives userspecified induction rules 
27067  683 
from wellfounded induction and completeness of patterns. This factors 
684 
out some operations that are done internally by the function package 

685 
and makes them available separately. See 

686 
src/HOL/ex/Induction_Scheme.thy for examples.

688 
* More flexible generation of measure functions for termination 

689 
proofs: Measure functions can be declared by proving a rule of the 

690 
form "is_measure f" and giving it the [measure_function] attribute. 

691 
The "is_measure" predicate is logically meaningless (always true), and 

692 
just guides the heuristic. To find suitable measure functions, the 

693 
termination prover sets up the goal "is_measure ?f" of the appropriate 

694 
type and generates all solutions by prologstyle backwards proof using 

695 
the declared rules. 

696 

697 
This setup also deals with rules like 

698 

699 
"is_measure f ==> is_measure (list_size f)" 

700 

701 
which accommodates nested datatypes that recurse through lists. 

702 
Similar rules are predeclared for products and option types.

1066 
implicit parameters according to the locale context), and polymorphic 

1067 
constants with qualified polymorphism (according to the class 

1068 
context). Within the body context of a 'class' target, a separate 

1069 
syntax layer ("user space type system") takes care of converting 

1070 
between global polymorphic consts and internal locale representation.

* Overloaded definitions are now actually checked for acyclic 
19714  1130 
dependencies. The overloading scheme is slightly more general than 
1131 
that of Haskell98, although Isabelle does not demand an exact 

1132 
correspondence to type class and instance declarations. 

1133 
INCOMPATIBILITY, use ``defs (unchecked overloaded)'' to admit more 

1134 
exotic versions of overloading  at the discretion of the user! 

19711  1135 

1136 
Polymorphic constants are represented via type arguments, i.e. the 

1137 
instantiation that matches an instance against the most general 

1138 
declaration given in the signature. For example, with the declaration 

1139 
c :: 'a => 'a => 'a, an instance c :: nat => nat => nat is represented 

1140 
as c(nat). Overloading is essentially simultaneous structural 

1141 
recursion over such type arguments. Incomplete specification patterns 

19714  1142 
impose global constraints on all occurrences, e.g. c('a * 'a) on the 
19715  1143 
LHS means that more general c('a * 'b) will be disallowed on any RHS. 
19714  1144 
Command 'print_theory' outputs the normalized system of recursive 
1145 
equations, see section "definitions".

* Isar: command 'declaration' augments a local theory by generic 
1180 
declaration functions written in ML. This enables arbitrary content 

1181 
being added to the context, depending on a morphism that tells the 

1182 
difference of the original declaration context wrt. the application 

1183 
context encountered later on. 

1184 

1185 
* Isar: proper interfaces for simplification procedures. Command 

1186 
'simproc_setup' declares named simprocs (with match patterns, and body 

1187 
text in ML). Attribute "simproc" adds/deletes simprocs in the current 

1188 
context. ML antiquotation @{simproc name} retrieves named simprocs. 

1189 

1190 
* Isar: an extra pair of brackets around attribute declarations 

1191 
abbreviates a theorem reference involving an internal dummy fact, 

1192 
which will be ignored later  only the effect of the attribute on 

1193 
the background context will persist. This form of inplace 

1194 
declarations is particularly useful with commands like 'declare' and 

1195 
'using', for example ``have A using [[simproc a]] by simp''.

* Isar: improper proof element 'guess' is like 'obtain', but derives 
1213 
the obtained context from the course of reasoning! For example: 

1214 

1215 
assume "EX x y. A x & B y"  "any previous fact" 

1216 
then guess x and y by clarify 

1217 

1218 
This technique is potentially adventurous, depending on the facts and 

1219 
proof tools being involved here. 

1220 

18020  1221 
* Isar: known facts from the proof context may be specified as literal 
1222 
propositions, using ASCII backquote syntax. This works wherever 

1223 
named facts used to be allowed so far, in proof commands, proof 

1224 
methods, attributes etc. Literal facts are retrieved from the context 

1225 
according to unification of type and term parameters. For example, 

1226 
provided that "A" and "A ==> B" and "!!x. P x ==> Q x" are known 

1227 
theorems in the current context, then these are valid literal facts: 

1228 
`A` and `A ==> B` and `!!x. P x ==> Q x" as well as `P a ==> Q a` etc. 

1229 

1230 
There is also a proof method "fact" which does the same composition 

18044  1231 
for explicit goal states, e.g. the following proof texts coincide with 
1232 
certain special cases of literal facts: 

18020  1233 

1234 
have "A" by fact == note `A` 

1235 
have "A ==> B" by fact == note `A ==> B` 

1236 
have "!!x. P x ==> Q x" by fact == note `!!x. P x ==> Q x` 

1237 
have "P a ==> Q a" by fact == note `P a ==> Q a`

1267 
simplifies the first three subgoals, while (rule foo, simp_all)[] 

1268 
simplifies all new goals that emerge from applying rule foo to the 

1269 
originally first one.

* Isar: the conclusion of a long theorem statement is now either 
1276 
'shows' (a simultaneous conjunction, as before), or 'obtains' 

1277 
(essentially a disjunction of cases with local parameters and 

1278 
assumptions). The latter allows to express general elimination rules 

18910  1279 
adequately; in this notation common elimination rules look like this: 
18901  1280 

1281 
lemma exE:  "EX x. P x ==> (!!x. P x ==> thesis) ==> thesis" 

1282 
assumes "EX x. P x" 

1283 
obtains x where "P x" 

1284 

1285 
lemma conjE:  "A & B ==> (A ==> B ==> thesis) ==> thesis" 

1286 
assumes "A & B" 

1287 
obtains A and B 

1288 

1289 
lemma disjE:  "A  B ==> (A ==> thesis) ==> (B ==> thesis) ==> thesis" 

1290 
assumes "A  B" 

1291 
obtains 

1292 
A 

1293 
 B 

1294 

18910  1295 
The subsequent classical rules even refer to the formal "thesis" 
18901  1296 
explicitly: 
1297 

1298 
lemma classical:  "(~ thesis ==> thesis) ==> thesis" 

1299 
obtains "~ thesis" 

1300 

18910  1301 
lemma Peirce's_Law:  "((thesis ==> something) ==> thesis) ==> thesis" 
1302 
obtains "thesis ==> something" 

18901  1303 

1304 
The actual proof of an 'obtains' statement is analogous to that of the 

18910  1305 
Isar proof element 'obtain', only that there may be several cases. 
1306 
Optional case names may be specified in parentheses; these will be 

1307 
available both in the present proof and as annotations in the 

1308 
resulting rule, for later use with the 'cases' method (cf. attribute 

1309 
case_names).

These specifications may be also used in a locale context. Then the 
1360 
constants being introduced depend on certain fixed parameters, and the 

1361 
constant name is qualified by the locale base name. An internal 

1362 
abbreviation takes care for convenient input and output, making the 

19088  1363 
parameters implicit and using the original short name. See also

entities from a monomorphic theory.
