* Theory headers: the new header syntax for Isar theories is 
10 

11 
theory <name> 

16234  12 
imports <theory1> ... <theoryN> 
13 
uses <file1> ... <fileM>

15 

16234  16

theory <name> = <theory1> + ... + <theoryN>:

will disappear in the next release. Use isatool fixheaders to convert 
21 
existing theory files. Note that there is no change in ancient

nonIsar theories now, but these will disappear soon.

*** Pure *** 

134 

135 
* Considerably improved version of 'constdefs' command. Now performs 

136 
automatic typeinference of declared constants; additional support for 

137 
local structure declarations (cf. locales and HOL records), see also 

138 
isarref manual. Potential INCOMPATIBILITY: need to observe strictly 

139 
sequential dependencies of definitions within a single 'constdefs' 

140 
section; moreover, the declared name needs to be an identifier. If 

141 
all fails, consider to fall back on 'consts' and 'defs' separately. 

142 

143 
* Improved indexed syntax and implicit structures. First of all, 

144 
indexed syntax provides a notational device for subscripted 

145 
application, using the new syntax \<^bsub>term\<^esub> for arbitrary 

146 
expressions. Secondly, in a local context with structure 

147 
declarations, number indexes \<^sub>n or the empty index (default 

148 
number 1) refer to a certain fixed variable implicitly; option 

149 
show_structs controls printing of implicit structures. Typical 

150 
applications of these concepts involve record types and locales. 

151 

152 
* New command 'no_syntax' removes grammar declarations (and 

153 
translations) resulting from the given syntax specification, which is 

154 
interpreted in the same manner as for the 'syntax' command. 

155 

156 
* 'Advanced' translation functions (parse_translation etc.) may depend 

157 
on the signature of the theory context being presently used for 

158 
parsing/printing, see also isarref manual. 

159 

16856  160 
* Improved 'oracle' command provides a typesafe interface to turn an 
161 
ML expression of type theory > T > term into a primitive rule of 

162 
type theory > T > thm (i.e. the functionality of Thm.invoke_oracle 

163 
is already included here); see also FOL/ex/IffExample.thy; 

164

* Improved internal renaming of symbolic identifiers  attach primes 
172 
instead of base 26 numbers. 

173 

174 
* New flag show_question_marks controls printing of leading question 

175 
marks in schematic variable names. 

176 

177 
* In schematic variable names, *any* symbol following \<^isub> or 

178 
\<^isup> is now treated as part of the base name. For example, the 

179 
following works without printing of awkward ".0" indexes: 

180 

181 
lemma "x\<^isub>1 = x\<^isub>2 ==> x\<^isub>2 = x\<^isub>1" 

182 
by simp 

183 

184 
* Inner syntax includes (*(*nested*) comments*). 

185 

17548  186 
* Pretty printer now supports unbreakable blocks, specified in mixfix 
16234  187 
annotations as "(00...)". 
188 

189 
* Clear separation of logical types and nonterminals, where the latter 

190 
may only occur in 'syntax' specifications or type abbreviations. 

191 
Before that distinction was only partially implemented via type class 

192 
"logic" vs. "{}". Potential INCOMPATIBILITY in rare cases of improper 

193 
use of 'types'/'consts' instead of 'nonterminals'/'syntax'. Some very 

194 
exotic syntax specifications may require further adaption 

17691  195 
(e.g. Cube/Cube.thy). 
16234  196 

197 
* Removed obsolete type class "logic", use the top sort {} instead. 

198 
Note that nonlogical types should be declared as 'nonterminals' 

199 
rather than 'types'. INCOMPATIBILITY for new objectlogic 

200 
specifications. 

201 

17095  202 
* Attributes 'induct' and 'cases': type or set names may now be 
203 
locally fixed variables as well. 

204 

16234  205 
* Simplifier: can now control the depth to which conditional rewriting 
206 
is traced via the PG menu Isabelle > Settings > Trace Simp Depth 

207 
Limit. 

208 

209 
* Simplifier: simplification procedures may now take the current 

210 
simpset into account (cf. Simplifier.simproc(_i) / mk_simproc 

211 
interface), which is very useful for calling the Simplifier 

212 
recursively. Minor INCOMPATIBILITY: the 'prems' argument of simprocs 

213 
is gone  use prems_of_ss on the simpset instead. Moreover, the 

214 
lowlevel mk_simproc no longer applies Logic.varify internally, to 

215 
allow for use in a context of fixed variables. 

216 

217

226 
INCOMPATIBILITY: elements of CPure (such as the CPure.intro /

228 
use isatool fixcpure to adapt your theory and ML sources.

*** Locales *** 

17095  253 

17385  254 
* New commands for the interpretation of locale expressions in 
255 
theories (1), locales (2) and proof contexts (3). These generate 

256 
proof obligations from the expression specification. After the 

257 
obligations have been discharged, theorems of the expression are added 

258 
to the theory, target locale or proof context. The synopsis of the 

259 
commands is a follows: 

260 

17095  261 
(1) interpretation expr inst 
262 
(2) interpretation target < expr 

263 
(3) interpret expr inst 

17385  264 

17095  265 
Interpretation in theories and proof contexts require a parameter 
266 
instantiation of terms from the current context. This is applied to 

17385  267 
specifications and theorems of the interpreted expression. 
268 
Interpretation in locales only permits parameter renaming through the 

269 
locale expression. Interpretation is smart in that interpretations 

270 
that are active already do not occur in proof obligations, neither are 

271 
instantiated theorems stored in duplicate. Use 'print_interps' to 

272 
inspect active interpretations of a particular locale. For details, 

17436  273 
see the Isar Reference manual. Examples can be found in 
274 
HOL/Finite_Set.thy and HOL/Algebra/UnivPoly.thy. 

16234  275 

276 
INCOMPATIBILITY: former 'instantiate' has been withdrawn, use 

277 
'interpret' instead. 

278 

17385  279 
* New context element 'constrains' for adding type constraints to 
280 
parameters. 

281 

282 
* Context expressions: renaming of parameters with syntax 

283 
redeclaration. 

17095  284 

285 
* Locale declaration: 'includes' disallowed. 

286 

16234  287 
* Proper static binding of attribute syntax  i.e. types / terms / 
288 
facts mentioned as arguments are always those of the locale definition 

289 
context, independently of the context of later invocations. Moreover, 

290 
locale operations (renaming and type / term instantiation) are applied 

291 
to attribute arguments as expected. 

292 

293 
INCOMPATIBILITY of the ML interface: always pass Attrib.src instead of 

294 
actual attributes; rare situations may require Attrib.attribute to 

295 
embed those attributes into Attrib.src that lack concrete syntax. 

296 
Attribute implementations need to cooperate properly with the static 

297 
binding mechanism. Basic parsers Args.XXX_typ/term/prop and 

298 
Attrib.XXX_thm etc. already do the right thing without further 

299 
intervention. Only unusual applications  such as "where" or "of" 

300 
(cf. src/Pure/Isar/attrib.ML), which process arguments depending both 

301 
on the context and the facts involved  may have to assign parsed 

302 
values to argument tokens explicitly. 

303 

304 
* Changed parameter management in theorem generation for long goal 

305 
statements with 'includes'. INCOMPATIBILITY: produces a different 

306 
theorem statement in rare situations. 

307 

17228  308 
* Locale inspection command 'print_locale' omits notes elements. Use 
309 
'print_locale!' to have them included in the output. 

310 

16234  311 

312 
*** Provers *** 

313 

314 
* Provers/hypsubst.ML: improved version of the subst method, for 

315 
singlestep rewriting: it now works in bound variable contexts. New is 

316 
'subst (asm)', for rewriting an assumption. INCOMPATIBILITY: may 

317 
rewrite a different subterm than the original subst method, which is 

318 
still available as 'simplesubst'. 

319 

320 
* Provers/quasi.ML: new transitivity reasoners for transitivity only 

321 
and quasi orders. 

322 

323 
* Provers/trancl.ML: new transitivity reasoner for transitive and 

324 
reflexivetransitive closure of relations. 

325 

326 
* Provers/blast.ML: new reference depth_limit to make blast's depth 

327 
limit (previously hardcoded with a value of 20) userdefinable. 

328 

329 
* Provers/simplifier.ML has been moved to Pure, where Simplifier.setup 

330 
is peformed already. Objectlogics merely need to finish their 

331 
initial simpset configuration as before. INCOMPATIBILITY.

syntax (epsilon) 

339 
"_Eps" :: "[pttrn, bool] => 'a" ("(3\<some>_./ _)" [0, 10] 10) 

340 

16234  341 
The symbol \<some> is displayed as the alternative epsilon of LaTeX 
342 
and xsymbol; use option 'm epsilon' to get it actually printed. 

343 
Moreover, the mathematically important symbolic identifier \<epsilon> 

344 
becomes available as variable, constant etc. INCOMPATIBILITY, 

345 

346 
* "x > y" abbreviates "y < x" and "x >= y" abbreviates "y <= x". 

347

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

instead of ":". 

353 

354 
* theory SetInterval: changed the syntax for open intervals: 

355 

356 
Old New 

357 
{..n(} {..<n} 

358 
{)n..} {n<..} 

359 
{m..n(} {m..<n} 

360 
{)m..n} {m<..n} 

361 
{)m..n(} {m<..<n} 

362 

363 
The old syntax is still supported but will disappear in the next 

364 
release. For conversion use the following Emacs search and replace 

365 
patterns (these are not perfect but work quite well): 

15046  366 

367 
{)\([^\.]*\)\.\. > {\1<\.\.} 

368 
\.\.\([^(}]*\)(} > \.\.<\1}

374 
* Theory Finite_Set: changed the syntax for 'setsum', summation over 
16234  375 
finite sets: "setsum (%x. e) A", which used to be "\<Sum>x:A. e", is 
17371  376 
now either "SUM x:A. e" or "\<Sum>x \<in> A. e". The bound variable can 
17189  377 
be a tuple pattern. 
16234  378 

379 
Some new syntax forms are available: 

380 

381 
"\<Sum>x  P. e" for "setsum (%x. e) {x. P}" 

382 
"\<Sum>x = a..b. e" for "setsum (%x. e) {a..b}" 

383 
"\<Sum>x = a..<b. e" for "setsum (%x. e) {a..<b}" 

384 
"\<Sum>x < k. e" for "setsum (%x. e) {..<k}" 

385 

386 
The latter form "\<Sum>x < k. e" used to be based on a separate 

387 
function "Summation", which has been discontinued. 

388 

389 
* theory Finite_Set: in structured induction proofs, the insert case 

390 
is now 'case (insert x F)' instead of the old counterintuitive 'case 

391 
(insert F x)'. 

392 

393 
* The 'refute' command has been extended to support a much larger 

394 
fragment of HOL, including axiomatic type classes, constdefs and 

395 
typedefs, inductive datatypes and recursion. 

396 

17619  397 
* New tactic 'sat' to prove propositional tautologies. Requires 
398 
zChaff with proof generation to be installed. 

399 

16234  400 
* Datatype induction via method 'induct' now preserves the name of the 
401 
induction variable. For example, when proving P(xs::'a list) by 

402 
induction on xs, the induction step is now P(xs) ==> P(a#xs) rather 

403 
than P(list) ==> P(a#list) as previously. Potential INCOMPATIBILITY 

404 
in unstructured proof scripts. 

405 

406 
* Reworked implementation of records. Improved scalability for 

407 
records with many fields, avoiding performance problems for type 

408 
inference. Records are no longer composed of nested field types, but 

409 
of nested extension types. Therefore the record type only grows linear 

410 
in the number of extensions and not in the number of fields. The 

411 
toplevel (users) view on records is preserved. Potential 

412 
INCOMPATIBILITY only in strange cases, where the theory depends on the 

413 
old record representation. The type generated for a record is called 

414 
<record_name>_ext_type. 

415 

416 
Flag record_quick_and_dirty_sensitive can be enabled to skip the 

417 
proofs triggered by a record definition or a simproc (if 

418 
quick_and_dirty is enabled). Definitions of large records can take 

419 
quite long. 

420 

421 
New simproc record_upd_simproc for simplification of multiple record 

422 
updates enabled by default. Moreover, trivial updates are also 

423 
removed: r(x := x r) = r. INCOMPATIBILITY: old proofs break 

424 
occasionally, since simplification is more powerful by default.

430

431 
provided by Provers/trancl.ML as additional solvers. INCOMPATIBILITY: 

432 
old proofs break occasionally as simplification may now solve more 

433 
goals than previously. 

434 

435 
* Simplifier: converts x <= y into x = y if assumption y <= x is 

436 
present. Works for all partial orders (class "order"), in particular 

437 
numbers and sets. For linear orders (e.g. numbers) it treats ~ x < y 

438 
just like y <= x. 

439 

440 
* Simplifier: new simproc for "let x = a in f x". If a is a free or 

441 
bound variable or a constant then the let is unfolded. Otherwise 

442 
first a is simplified to b, and then f b is simplified to g. If 

443 
possible we abstract b from g arriving at "let x = b in h x", 

444 
otherwise we unfold the let and arrive at g. The simproc can be 

445 
enabled/disabled by the reference use_let_simproc. Potential 

446 
INCOMPATIBILITY since simplification is more powerful by default.

1022 
(\<aa>...\<zz>\<AA>...\<ZZ>), calligraphic (\<A>...\<Z>), and Euler 

14173  1023 
(\<a>...\<z>), are now considered normal letters, and can therefore 
1024 
be used anywhere where an ASCII letter (a...zA...Z) has until 

1025 
now. COMPATIBILITY: This obviously changes the parsing of some 

1026 
terms, especially where a symbol has been used as a binder, say 

1027 
'\<Pi>x. ...', which is now a type error since \<Pi>x will be parsed 

1028 
as an identifier. Fix it by inserting a space around former 

1029 
symbols. Call 'isatool fixgreek' to try to fix parsing errors in 

1030 
existing theory and ML files.

from "\Union x \in A. B" to "\Union_{x \in A} B" 

1169 
i.e. the index formulae has become a subscript. 

1170 
Similarly for "\Union x. B", and for \Inter instead of \Union. 

14380  1171 

14418  1172 
* Unions and Intersections over Intervals: 
14731  1173 
There is new short syntax "UN i<=n. A" for "UN i:{0..n}. A". There is 
1174 
also an xsymbol version with subscripts "\<Union>\<^bsub>i <= n\<^esub>. A" 

14418  1175 
like in normal math, and corresponding versions for < and for intersection. 
1176 

15677  1177 
* HOL/List: Ordering "lexico" is renamed "lenlex" and the standard 
1178 
lexicographic dictonary ordering has been added as "lexord". 

1179 

14401  1180 
* ML: the legacy theory structures Int and List have been removed. They had 
1181 
conflicted with ML Basis Library structures having the same names. 

14380  1182 

14464  1183 
* 'refute' command added to search for (finite) countermodels. Only works 
1184 
for a fragment of HOL. The installation of an external SAT solver is 

1185 
highly recommended. See "HOL/Refute.thy" for details. 

1186 

14602  1187 
* 'quickcheck' command: Allows to find counterexamples by evaluating 
1188 
formulae under an assignment of free variables to random values. 

1189 
In contrast to 'refute', it can deal with inductive datatypes, 

1190 
but cannot handle quantifiers. See "HOL/ex/Quickcheck_Examples.thy" 

1191 
for examples.

1204 

13618  1205 
* Provers/simplifier: 
1206 

13781  1207 
 Completely reimplemented method simp (ML: Asm_full_simp_tac): 
13618  1208 
Assumptions are now subject to complete mutual simplification, 
1209 
not just from left to right. The simplifier now preserves 

1210 
the order of assumptions. 

1211 

1212 
Potential INCOMPATIBILITY: 

1213 

13781  1214 
 simp sometimes diverges where the old version did 
1215 
not, e.g. invoking simp on the goal 

13618  1216 

1217 
[ P (f x); y = x; f x = f y ] ==> Q 

1218 

13781  1219 
now gives rise to the infinite reduction sequence 
1220 

1221 
P(f x) (f x = f y)> P(f y) (y = x)> P(f x) (f x = f y)> ... 

1222 

1223 
Using "simp (asm_lr)" (ML: Asm_lr_simp_tac) instead often solves this 

1224 
kind of problem. 

1225 

1226 
 Tactics combining classical reasoner and simplification (such as auto) 

1227 
are also affected by this change, because many of them rely on 

1228 
simp. They may sometimes diverge as well or yield a different numbers 

1229 
of subgoals. Try to use e.g. force, fastsimp, or safe instead of auto 

1230 
in case of problems. Sometimes subsequent calls to the classical 

1231 
reasoner will fail because a preceeding call to the simplifier too 

1232 
eagerly simplified the goal, e.g. deleted redundant premises. 

13618  1233 

1234 
 The simplifier trace now shows the names of the applied rewrite rules 

1235 

13829  1236 
 You can limit the number of recursive invocations of the simplifier 
1237 
during conditional rewriting (where the simplifie tries to solve the 

1238 
conditions before applying the rewrite rule): 

1239 
ML "simp_depth_limit := n" 

1240 
where n is an integer. Thus you can force termination where previously 

1241 
the simplifier would diverge.

 No longer aborts on failed congruence proof. Instead, the

1249 
proofs. See HOL/Extraction.thy for an example instantiation, as well 

1250 
as HOL/Extraction for some case studies. 

1251 

13868  1252 
* Pure: The main goal of the proof state is no longer shown by default, only 
1253 
the subgoals. This behaviour is controlled by a new flag.

The rules are ordered by how closely they match the subgoal.
