* Theory headers: the new header syntax for Isar theories is

11 
theory <name>

imports <theory1> ... <theoryN> 
13 
uses <file1> ... <fileM>

will disappear in the next release. Use isatool fixheaders to convert

nonIsar theories now, but these will disappear soon.

*** Pure *** 

131 

132 
* Considerably improved version of 'constdefs' command. Now performs 

133 
automatic typeinference of declared constants; additional support for 

134 
local structure declarations (cf. locales and HOL records), see also 

135 
isarref manual. Potential INCOMPATIBILITY: need to observe strictly 

136 
sequential dependencies of definitions within a single 'constdefs' 

137 
section; moreover, the declared name needs to be an identifier. If 

138 
all fails, consider to fall back on 'consts' and 'defs' separately. 

139 

140 
* Improved indexed syntax and implicit structures. First of all, 

141 
indexed syntax provides a notational device for subscripted 

142 
application, using the new syntax \<^bsub>term\<^esub> for arbitrary 

143 
expressions. Secondly, in a local context with structure 

144 
declarations, number indexes \<^sub>n or the empty index (default 

145 
number 1) refer to a certain fixed variable implicitly; option 

146 
show_structs controls printing of implicit structures. Typical 

147 
applications of these concepts involve record types and locales. 

148 

149 
* New command 'no_syntax' removes grammar declarations (and 

150 
translations) resulting from the given syntax specification, which is 

151 
interpreted in the same manner as for the 'syntax' command. 

152 

153 
* 'Advanced' translation functions (parse_translation etc.) may depend 

154 
on the signature of the theory context being presently used for 

155 
parsing/printing, see also isarref manual. 

156 

16856  157 
* Improved 'oracle' command provides a typesafe interface to turn an 
158 
ML expression of type theory > T > term into a primitive rule of 

159 
type theory > T > thm (i.e. the functionality of Thm.invoke_oracle 

160 
is already included here); see also FOL/ex/IffExample.thy;

* Improved internal renaming of symbolic identifiers  attach primes 
169 
instead of base 26 numbers. 

170 

171 
* New flag show_question_marks controls printing of leading question 

172 
marks in schematic variable names. 

173 

174 
* In schematic variable names, *any* symbol following \<^isub> or 

175 
\<^isup> is now treated as part of the base name. For example, the 

176 
following works without printing of awkward ".0" indexes: 

177 

178 
lemma "x\<^isub>1 = x\<^isub>2 ==> x\<^isub>2 = x\<^isub>1" 

179 
by simp 

180 

181 
* Inner syntax includes (*(*nested*) comments*). 

182 

183 
* Pretty pinter now supports unbreakable blocks, specified in mixfix 

184 
annotations as "(00...)". 

185 

186 
* Clear separation of logical types and nonterminals, where the latter 

187 
may only occur in 'syntax' specifications or type abbreviations. 

188 
Before that distinction was only partially implemented via type class 

189 
"logic" vs. "{}". Potential INCOMPATIBILITY in rare cases of improper 

190 
use of 'types'/'consts' instead of 'nonterminals'/'syntax'. Some very 

191 
exotic syntax specifications may require further adaption 

192 
(e.g. Cube/Base.thy). 

193 

194 
* Removed obsolete type class "logic", use the top sort {} instead. 

195 
Note that nonlogical types should be declared as 'nonterminals' 

196 
rather than 'types'. INCOMPATIBILITY for new objectlogic 

197 
specifications. 

198 

17095  199 
* Attributes 'induct' and 'cases': type or set names may now be 
200 
locally fixed variables as well. 

201 

16234  202 
* Simplifier: can now control the depth to which conditional rewriting 
203 
is traced via the PG menu Isabelle > Settings > Trace Simp Depth 

204 
Limit. 

205 

206 
* Simplifier: simplification procedures may now take the current 

207 
simpset into account (cf. Simplifier.simproc(_i) / mk_simproc 

208 
interface), which is very useful for calling the Simplifier 

209 
recursively. Minor INCOMPATIBILITY: the 'prems' argument of simprocs 

210 
is gone  use prems_of_ss on the simpset instead. Moreover, the 

211 
lowlevel mk_simproc no longer applies Logic.varify internally, to 

212 
allow for use in a context of fixed variables. 

213 

214 
* thin_tac now works even if the assumption being deleted contains !! 

215 
or ==>. More generally, erule now works even if the major premise of 

216 
the elimination rule contains !! or ==>.

218 
* Reorganized bootstrapping of the Pure theories; CPure is now derived 

219 
from Pure, which contains all common declarations already. Both 

220 
theories are defined via plain Isabelle/Isar .thy files. 

221 
INCOMPATIBILITY: elements of CPure (such as the CPure.intro / 

222 
CPure.elim / CPure.dest attributes) now appear in the Pure name space; 

223 
use isatool fixcpure to adapt your theory and ML sources.

*** Locales *** 

17095  239 

17385  240 
* New commands for the interpretation of locale expressions in 
241 
theories (1), locales (2) and proof contexts (3). These generate 

242 
proof obligations from the expression specification. After the 

243 
obligations have been discharged, theorems of the expression are added 

244 
to the theory, target locale or proof context. The synopsis of the 

245 
commands is a follows: 

246 

17095  247 
(1) interpretation expr inst 
248 
(2) interpretation target < expr 

249 
(3) interpret expr inst 

17385  250 

17095  251 
Interpretation in theories and proof contexts require a parameter 
252 
instantiation of terms from the current context. This is applied to 

17385  253 
specifications and theorems of the interpreted expression. 
254 
Interpretation in locales only permits parameter renaming through the 

255 
locale expression. Interpretation is smart in that interpretations 

256 
that are active already do not occur in proof obligations, neither are 

257 
instantiated theorems stored in duplicate. Use 'print_interps' to 

258 
inspect active interpretations of a particular locale. For details, 

17436  259 
see the Isar Reference manual. Examples can be found in 
260 
HOL/Finite_Set.thy and HOL/Algebra/UnivPoly.thy. 

16234  261 

262 
INCOMPATIBILITY: former 'instantiate' has been withdrawn, use 

263 
'interpret' instead. 

264 

17385  265 
* New context element 'constrains' for adding type constraints to 
266 
parameters. 

267 

268 
* Context expressions: renaming of parameters with syntax 

269 
redeclaration. 

17095  270 

271 
* Locale declaration: 'includes' disallowed. 

272 

16234  273 
* Proper static binding of attribute syntax  i.e. types / terms / 
274 
facts mentioned as arguments are always those of the locale definition 

275 
context, independently of the context of later invocations. Moreover, 

276 
locale operations (renaming and type / term instantiation) are applied 

277 
to attribute arguments as expected. 

278 

279 
INCOMPATIBILITY of the ML interface: always pass Attrib.src instead of 

280 
actual attributes; rare situations may require Attrib.attribute to 

281 
embed those attributes into Attrib.src that lack concrete syntax. 

282 
Attribute implementations need to cooperate properly with the static 

283 
binding mechanism. Basic parsers Args.XXX_typ/term/prop and 

284 
Attrib.XXX_thm etc. already do the right thing without further 

285 
intervention. Only unusual applications  such as "where" or "of" 

286 
(cf. src/Pure/Isar/attrib.ML), which process arguments depending both 

287 
on the context and the facts involved  may have to assign parsed 

288 
values to argument tokens explicitly. 

289 

290 
* Changed parameter management in theorem generation for long goal 

291 
statements with 'includes'. INCOMPATIBILITY: produces a different 

292 
theorem statement in rare situations. 

293 

17228  294 
* Locale inspection command 'print_locale' omits notes elements. Use 
295 
'print_locale!' to have them included in the output. 

296 

16234  297 

298 
*** Provers *** 

299 

300 
* Provers/hypsubst.ML: improved version of the subst method, for 

301 
singlestep rewriting: it now works in bound variable contexts. New is 

302 
'subst (asm)', for rewriting an assumption. INCOMPATIBILITY: may 

303 
rewrite a different subterm than the original subst method, which is 

304 
still available as 'simplesubst'. 

305 

306 
* Provers/quasi.ML: new transitivity reasoners for transitivity only 

307 
and quasi orders. 

308 

309 
* Provers/trancl.ML: new transitivity reasoner for transitive and 

310 
reflexivetransitive closure of relations. 

311 

312 
* Provers/blast.ML: new reference depth_limit to make blast's depth 

313 
limit (previously hardcoded with a value of 20) userdefinable. 

314 

315 
* Provers/simplifier.ML has been moved to Pure, where Simplifier.setup 

316 
is peformed already. Objectlogics merely need to finish their 

317 
initial simpset configuration as before. INCOMPATIBILITY.

324 
syntax (epsilon) 

325 
"_Eps" :: "[pttrn, bool] => 'a" ("(3\<some>_./ _)" [0, 10] 10) 

326 

16234  327 
The symbol \<some> is displayed as the alternative epsilon of LaTeX 
328 
and xsymbol; use option 'm epsilon' to get it actually printed. 

329 
Moreover, the mathematically important symbolic identifier \<epsilon> 

330 
becomes available as variable, constant etc. INCOMPATIBILITY, 

331 

332 
* "x > y" abbreviates "y < x" and "x >= y" abbreviates "y <= x". 

333 
Similarly for all quantifiers: "ALL x > y" etc. The xsymbol for >=

is \<ge>. New transitivity rules have been added to HOL/Orderings.thy to

* "{x:A. P}" abbreviates "{x. x:A & P}", and similarly for "\<in>" 

338 
instead of ":". 

339 

340 
* theory SetInterval: changed the syntax for open intervals: 

341 

342 
Old New 

343 
{..n(} {..<n} 

344 
{)n..} {n<..} 

345 
{m..n(} {m..<n} 

346 
{)m..n} {m<..n} 

347 
{)m..n(} {m<..<n} 

348 

349 
The old syntax is still supported but will disappear in the next 

350 
release. For conversion use the following Emacs search and replace 

351 
patterns (these are not perfect but work quite well): 

15046  352 

353 
{)\([^\.]*\)\.\. > {\1<\.\.}

358 
* Theory Finite_Set: changed the syntax for 'setsum', summation over 
16234  359 
finite sets: "setsum (%x. e) A", which used to be "\<Sum>x:A. e", is 
17371  360 
now either "SUM x:A. e" or "\<Sum>x \<in> A. e". The bound variable can 
17189  361 
be a tuple pattern. 
16234  362 

363 
Some new syntax forms are available: 

364 

365 
"\<Sum>x  P. e" for "setsum (%x. e) {x. P}" 

366 
"\<Sum>x = a..b. e" for "setsum (%x. e) {a..b}" 

367 
"\<Sum>x = a..<b. e" for "setsum (%x. e) {a..<b}" 

368 
"\<Sum>x < k. e" for "setsum (%x. e) {..<k}" 

369 

370 
The latter form "\<Sum>x < k. e" used to be based on a separate 

371 
function "Summation", which has been discontinued. 

372 

373 
* theory Finite_Set: in structured induction proofs, the insert case 

374 
is now 'case (insert x F)' instead of the old counterintuitive 'case 

375 
(insert F x)'. 

376 

377 
* The 'refute' command has been extended to support a much larger 

378 
fragment of HOL, including axiomatic type classes, constdefs and 

379 
typedefs, inductive datatypes and recursion. 

380 

381 
* Datatype induction via method 'induct' now preserves the name of the 

382 
induction variable. For example, when proving P(xs::'a list) by 

383 
induction on xs, the induction step is now P(xs) ==> P(a#xs) rather 

384 
than P(list) ==> P(a#list) as previously. Potential INCOMPATIBILITY 

385 
in unstructured proof scripts. 

386 

387 
* Reworked implementation of records. Improved scalability for 

388 
records with many fields, avoiding performance problems for type 

389 
inference. Records are no longer composed of nested field types, but 

390 
of nested extension types. Therefore the record type only grows linear 

391 
in the number of extensions and not in the number of fields. The 

392 
toplevel (users) view on records is preserved. Potential 

393 
INCOMPATIBILITY only in strange cases, where the theory depends on the 

394 
old record representation. The type generated for a record is called 

395 
<record_name>_ext_type. 

396 

397 
Flag record_quick_and_dirty_sensitive can be enabled to skip the 

398 
proofs triggered by a record definition or a simproc (if 

399 
quick_and_dirty is enabled). Definitions of large records can take 

400 
quite long. 

401 

402 
New simproc record_upd_simproc for simplification of multiple record 

403 
updates enabled by default. Moreover, trivial updates are also 

404 
removed: r(x := x r) = r. INCOMPATIBILITY: old proofs break 

405 
occasionally, since simplification is more powerful by default.

412 
provided by Provers/trancl.ML as additional solvers. INCOMPATIBILITY: 

413 
old proofs break occasionally as simplification may now solve more 

414 
goals than previously. 

415 

416 
* Simplifier: converts x <= y into x = y if assumption y <= x is 

417 
present. Works for all partial orders (class "order"), in particular 

418 
numbers and sets. For linear orders (e.g. numbers) it treats ~ x < y 

419 
just like y <= x. 

420 

421 
* Simplifier: new simproc for "let x = a in f x". If a is a free or 

422 
bound variable or a constant then the let is unfolded. Otherwise 

423 
first a is simplified to b, and then f b is simplified to g. If 

424 
possible we abstract b from g arriving at "let x = b in h x", 

425 
otherwise we unfold the let and arrive at g. The simproc can be 

426 
enabled/disabled by the reference use_let_simproc. Potential 

427

917 
(\<aa>...\<zz>\<AA>...\<ZZ>), calligraphic (\<A>...\<Z>), and Euler 

14173  918

920 
now. COMPATIBILITY: This obviously changes the parsing of some 

921 
terms, especially where a symbol has been used as a binder, say 

922 
'\<Pi>x. ...', which is now a type error since \<Pi>x will be parsed 

923 
as an identifier. Fix it by inserting a space around former 

924 
symbols. Call 'isatool fixgreek' to try to fix parsing errors in

* Unions and Intersections: 
15119  1062 
The latex output syntax of UN and INT has been changed 
1063 
from "\Union x \in A. B" to "\Union_{x \in A} B" 

1064 
i.e. the index formulae has become a subscript. 

1065 
Similarly for "\Union x. B", and for \Inter instead of \Union. 

14380  1066 

14418  1067 
* Unions and Intersections over Intervals: 
14731  1068 
There is new short syntax "UN i<=n. A" for "UN i:{0..n}. A". There is 
1069 
also an xsymbol version with subscripts "\<Union>\<^bsub>i <= n\<^esub>. A" 

14418  1070 
like in normal math, and corresponding versions for < and for intersection. 
1071 

15677  1072 
* HOL/List: Ordering "lexico" is renamed "lenlex" and the standard 
1073 
lexicographic dictonary ordering has been added as "lexord". 

1074 

14401  1075 
* ML: the legacy theory structures Int and List have been removed. They had 
1076 
conflicted with ML Basis Library structures having the same names. 

14380  1077 

14464  1078 
* 'refute' command added to search for (finite) countermodels. Only works 
1079 
for a fragment of HOL. The installation of an external SAT solver is 

1080 
highly recommended. See "HOL/Refute.thy" for details. 

1081 

14602  1082 
* 'quickcheck' command: Allows to find counterexamples by evaluating 
1083 
formulae under an assignment of free variables to random values. 

1084 
In contrast to 'refute', it can deal with inductive datatypes, 

1085 
but cannot handle quantifiers. See "HOL/ex/Quickcheck_Examples.thy" 

1086 
for examples.

13618  1100 
* Provers/simplifier: 
1101 

13781  1102 
 Completely reimplemented method simp (ML: Asm_full_simp_tac): 
13618  1103 
Assumptions are now subject to complete mutual simplification, 
1104 
not just from left to right. The simplifier now preserves 

1105 
the order of assumptions. 

1106 

1107 
Potential INCOMPATIBILITY: 

1108 

13781  1109 
 simp sometimes diverges where the old version did 
1110 
not, e.g. invoking simp on the goal 

13618  1111 

1112 
[ P (f x); y = x; f x = f y ] ==> Q 

1113 

13781  1114 
now gives rise to the infinite reduction sequence 
1115 

1116 
P(f x) (f x = f y)> P(f y) (y = x)> P(f x) (f x = f y)> ... 

1117 

1118 
Using "simp (asm_lr)" (ML: Asm_lr_simp_tac) instead often solves this 

1119 
kind of problem. 

1120 

1121 
 Tactics combining classical reasoner and simplification (such as auto) 

1122 
are also affected by this change, because many of them rely on 

1123 
simp. They may sometimes diverge as well or yield a different numbers 

1124 
of subgoals. Try to use e.g. force, fastsimp, or safe instead of auto 

1125 
in case of problems. Sometimes subsequent calls to the classical 

1126 
reasoner will fail because a preceeding call to the simplifier too 

1127 
eagerly simplified the goal, e.g. deleted redundant premises. 

13618  1128 

1129 
 The simplifier trace now shows the names of the applied rewrite rules 

1130 

13829  1131 
 You can limit the number of recursive invocations of the simplifier 
1132 
during conditional rewriting (where the simplifie tries to solve the 

1133 
conditions before applying the rewrite rule): 

1134 
ML "simp_depth_limit := n" 

1135 
where n is an integer. Thus you can force termination where previously 

1136 
the simplifier would diverge.

1144

1145 
as HOL/Extraction for some case studies. 

1146 

13868  1147

1148

 'case' command admits impromptu naming of parameters (such as 
1354 
"case (Suc n)"); 

1355 
 'induct' method divinates rule instantiation from the inductive 

1356 
claim; no longer requires excessive ?P bindings for proper 

1357 
instantiation of cases; 

1358 
 'induct' method properly enumerates all possibilities of set/type 

1359 
rules; as a consequence facts may be also passed through *type* 

1360 
rules without further ado; 

1361 
 'induct' method now derives symbolic cases from the *rulified* 

1362 
rule (before it used to rulify cases stemming from the internal 

1363 
atomized version); this means that the context of a nonatomic 

1364 
statement becomes is included in the hypothesis, avoiding the 

1365 
slightly cumbersome show "PROP ?case" form; 

1366 
 'induct' may now use elimstyle induction rules without chaining 

1367 
facts, using ``missing'' premises from the goal state; this allows 

1368 
rules stemming from inductive sets to be applied in unstructured 

1369 
scripts, while still benefitting from proper handling of nonatomic 

1370 
statements; NB: major inductive premises need to be put first, all 

1371 
the rest of the goal is passed through the induction;
