* Significantly improved Isabelle/Isar implementation manual.

* Source files are always encoded as UTF8, instead of oldfashioned 
12 
ISOLatin1. INCOMPATIBILITY. Isabelle LaTeX documents might require

40948  26 
* System settings: ISABELLE_HOME_USER now includes ISABELLE_IDENTIFIER 
27 
(and thus refers to something like $HOME/.isabelle/IsabelleXXXX), 

28 
while the default heap location within that directory lacks that extra 

29 
suffix. This isolates multiple Isabelle installations from each 

30 
other, avoiding problems with old settings in new versions. 

31 
INCOMPATIBILITY, need to copy/upgrade old user settings manually.

* New command 'partial_function' provides basic support for recursive 
40194  162 
function definitions over complete partial orders. Concrete instances 
40183  163 
are provided for i) the option type, ii) tail recursion on arbitrary 
164 
types, and iii) the heap monad of Imperative_HOL. See 

165 
HOL/ex/Fundefs.thy and HOL/Imperative_HOL/ex/Linked_Lists.thy for 

166 
examples. 

167 

41398  168 
* Scala (2.8 or higher) has been added to the target languages of the 
169 
code generator. 

170 

171 
* Inductive package: offers new command 'inductive_simps' to 

172 
automatically derive instantiated and simplified equations for 

173 
inductive predicates, similar to 'inductive_cases'. 

174 

175 
* Function package: .psimps rules are no longer implicitly declared 

176 
[simp]. INCOMPATIBILITY. 

177 

178 
* Datatype package: theorems generated for executable equality (class 

179 
eq) carry proper names and are treated as default code equations. 

180 

41510  181 
* New command 'enriched_type' allows to register properties of 
41397  182 
the functorial structure of types. 
183 

41398  184 
* Weaker versions of the "meson" and "metis" proof methods are now 
185 
available in "HOLPlain", without dependency on "Hilbert_Choice". The 

186 
proof methods become more powerful after "Hilbert_Choice" is loaded in 

187 
"HOLMain". 

39771  188 

39644  189 
* Improved infrastructure for term evaluation using code generator 
190 
techniques, in particular static evaluation conversions. 

191 

41398  192 
* Code generator: globbing constant expressions "*" and "Theory.*" 
193 
have been replaced by the more idiomatic "_" and "Theory._". 

194 
INCOMPATIBILITY. 

195 

196 
* Code generator: export_code without explicit file declaration prints 

197 
to standard output. INCOMPATIBILITY. 

198 

199 
* Code generator: do not print function definitions for case 

200 
combinators any longer. 

201 

202 
* Simplification with rules determined by code generator 

203 
with code_simp.ML and method code_simp. 

204 

205 
* Records: logical foundation type for records does not carry a '_type' 

40948  206 
suffix any longer. INCOMPATIBILITY. 
207 

208 
* Code generation for records: more idiomatic representation of record 

209 
types. Warning: records are not covered by ancient SML code 

210 
generation any longer. INCOMPATIBILITY. In cases of need, a suitable 

211 
rep_datatype declaration helps to succeed then: 

38537  212 

213 
record 'a foo = ... 

214 
... 

215 
rep_datatype foo_ext ... 

38535  216 

41398  217 
* Quickcheck now by default uses exhaustive testing instead of random 
218 
testing. Random testing can be invoked by quickcheck[random], 

219 
exhaustive testing by quickcheck[exhaustive]. 

220 

221 
* Quickcheck instantiates polymorphic types with small finite 

222 
datatypes by default. This enables a simple execution mechanism to 

223 
handle quantifiers and function equality over the finite datatypes. 

224 

225 
* Quickcheck's generator for random generation is renamed from "code" 

226 
to "random". INCOMPATIBILITY. 

227 

228 
* Quickcheck now has a configurable time limit which is set to 30 

229 
seconds by default. This can be changed by adding [timeout = n] to the 

230 
quickcheck command. The time limit for Auto Quickcheck is still set 

231 
independently. 

38461  232 

233 
* Quickcheck in locales considers interpretations of that locale for 

234 
counter example search.

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

529 
former command 'new_domain' is now called 'domain'. To use the domain 

530 
package in its original axiomatic mode, use 'domain (unsafe)'. 

531 
INCOMPATIBILITY. 

532 

41401  533 
* The new class 'domain' is now the default sort. Class 'predomain' is 
534 
an unpointed version of 'domain'. Theories can be updated by replacing 

535 
sort annotations as shown below. INCOMPATIBILITY.

* The old type class 'rep' has been superseded by class 'domain'. 

542 
Accordingly, users of the definitional package must remove any 

543 
'default_sort rep' declarations. INCOMPATIBILITY. 

544 

41401  545 
* The domain package (definitional mode) now supports unpointed 
546 
predomain argument types, as long as they are marked 'lazy'. (Strict 

547 
arguments must be in class 'domain'.) For example, the following 

548 
domain definition now works: 

549 

550 
domain natlist = nil  cons (lazy "nat discr") (lazy "natlist") 

551 

552 
* Theory HOLCF/Library/HOL_Cpo provides cpo and predomain class 

553 
instances for types from Isabelle/HOL: bool, nat, int, char, 'a + 'b, 

554 
'a option, and 'a list. Additionally, it configures fixrec and the 

555 
domain package to work with these types. For example: 

556 

557 
fixrec isInl :: "('a + 'b) u > tr" 

558 
where "isInl$(up$(Inl x)) = TT"  "isInl$(up$(Inr y)) = FF"

560 
domain V = VFun (lazy "V > V")  VCon (lazy "nat") (lazy "V list")

* Authentic syntax for *all* logical entities (type classes, type 
785 
constructors, term constants): provides simple and robust 

786 
correspondence between formal entities and concrete syntax. Within 

787 
the parse tree / AST representations, "constants" are decorated by 

788 
their category (class, type, const) and spelled out explicitly with 

789 
their full internal name. 

790 

791 
Substantial INCOMPATIBILITY concerning lowlevel syntax declarations 

792 
and translations (translation rules and translation functions in ML). 

793 
Some hints on upgrading: 

35260  794 

795 
 Many existing uses of 'syntax' and 'translations' can be replaced 

35436  796 
by more modern 'type_notation', 'notation' and 'abbreviation', 
797 
which are independent of this issue. 

35260  798 

799 
 'translations' require markup within the AST; the term syntax 

800 
provides the following special forms: 

801 

802 
CONST c  produces syntax version of constant c from context 

35261  803 
XCONST c  literally c, checked as constant from context 
804 
c  literally c, if declared by 'syntax' 

805 

806 
Plain identifiers are treated as AST variables  occasionally the 

807 
system indicates accidental variables via the error "rhs contains 

808 
extra variables". 

35260  809 

35436  810 
Type classes and type constructors are marked according to their 
811 
concrete syntax. Some old translations rules need to be written 

812 
for the "type" category, using type constructor application 

813 
instead of pseudoterm application of the default category 

814 
"logic". 

815 

35260  816 
 'parse_translation' etc. in ML may use the following 
817 
antiquotations: 

818 

35436  819 
@{class_syntax c}  type class c within parse tree / AST 
820 
@{term_syntax c}  type constructor c within parse tree / AST 

35260  821 
@{const_syntax c}  ML version of "CONST c" above 
822 
@{syntax_const c}  literally c (checked wrt. 'syntax' declarations) 

823 

35436  824 
 Literal types within 'typed_print_translations', i.e. those *not* 
825 
represented as pseudoterms are represented verbatim. Use @{class 

826 
c} or @{type_name c} here instead of the above syntax 

827 
antiquotations. 

828 

35260  829 
Note that old nonauthentic syntax was based on unqualified base 
35436  830 
names, so all of the above "constant" names would coincide. Recall 
831 
that 'print_syntax' and ML_command "set Syntax.trace_ast" help to 

832 
diagnose syntax problems.

* Command 'typedef' now works within a local theory context  without 
929 
introducing dependencies on parameters or assumptions, which is not 

930 
possible in Isabelle/Pure/HOL. Note that the logical environment may 

931 
contain multiple interpretations of local typedefs (with different 

932 
nonemptiness proofs), even in a global theory context. 

933 

934 
* New package for quotient types. Commands 'quotient_type' and 

935 
'quotient_definition' may be used for defining types and constants by 

936 
quotient constructions. An example is the type of integers created by 

937 
quotienting pairs of natural numbers: 

37380  938 

37351  939 
fun 
37380  940 
intrel :: "(nat * nat) => (nat * nat) => bool" 
37351  941 
where 
942 
"intrel (x, y) (u, v) = (x + v = u + y)" 

943 

37380  944 
quotient_type int = "nat * nat" / intrel 
37351  945 
by (auto simp add: equivp_def expand_fun_eq) 
37380  946 

37351  947 
quotient_definition 
948 
"0::int" is "(0::nat, 0::nat)" 

949 

950 
The method "lifting" can be used to lift of theorems from the 

951 
underlying "raw" type to the quotient type. The example 

952 
src/HOL/Quotient_Examples/FSet.thy includes such a quotient 

953 
construction and provides a reasoning infrastructure for finite sets. 

954 

955 
* Renamed Library/Quotient.thy to Library/Quotient_Type.thy to avoid 

956 
clash with new theory Quotient in Main HOL. 

957 

958 
* Moved the SMT binding into the main HOL session, eliminating 

959 
separate HOLSMT session.

1320 

1321 
@{class NAME}  type class 

1322 
@{class_syntax NAME}  syntax representation of the above 

1323 

1324 
@{type_name NAME}  logical type 

1325 
@{type_abbrev NAME}  type abbreviation 

1326 
@{nonterminal NAME}  type of concrete syntactic category 

1327 
@{type_syntax NAME}  syntax representation of any of the above 

1328 

1329 
@{const_name NAME}  logical constant (INCOMPATIBILITY) 

1330 
@{const_abbrev NAME}  abbreviated constant 

1331 
@{const_syntax NAME}  syntax representation of any of the above 

1332 

1333 
* Antiquotation @{syntax_const NAME} ensures that NAME refers to a raw 

1334 
syntax constant (cf. 'syntax' command). 

1335 

1336 
* Antiquotation @{make_string} inlines a function to print arbitrary 

1337 
values similar to the ML toplevel. The result is compiler dependent 

1338 
and may fall back on "?" in certain situations. 

1339 

1340 
* Diagnostic commands 'ML_val' and 'ML_command' may refer to 

1341 
antiquotations @{Isar.state} and @{Isar.goal}. This replaces impure 

1342 
Isar.state() and Isar.goal(), which belong to the old TTY loop and do 

1343 
not work with the asynchronous Isar document model. 

1344 

1345 
* Configuration options now admit dynamic default values, depending on 

1346 
the context or even global references. 

1347 

1348 
* SHA1.digest digests strings according to SHA1 (see RFC 3174). It 

1349 
uses an efficient external library if available (for Poly/ML).

1352 
for some time as aliases within the structure Legacy:

1365 
Note that "open Legacy" simplifies porting of sources, but forgetting 

1366 
to remove it again will complicate porting again in the future. 

1367 

1368 
* Most operations that refer to a global context are named 

1369 
accordingly, e.g. Simplifier.global_context or 

1370 
ProofContext.init_global. There are some situations where a global 

1371 
context actually works, but under normal circumstances one needs to 

1372 
pass the proper local context through the code! 

1373 

1374 
* Discontinued old TheoryDataFun with its copy/init operation  data 

1375 
needs to be pure. Functor Theory_Data_PP retains the traditional 

1376 
Pretty.pp argument to merge, which is absent in the standard 

1377 
Theory_Data version.

37144  1379 
* Sorts.certify_sort and derived "cert" operations for types and terms 
1380 
no longer minimize sorts. Thus certification at the boundary of the 

1381 
inference kernel becomes invariant under addition of class relations, 

1382 
which is an important monotonicity principle. Sorts are now minimized 

1383 
in the syntax layer only, at the boundary between the enduser and the 

1384 
system. Subtle INCOMPATIBILITY, may have to use Sign.minimize_sort 

1385 
explicitly in rare situations.
