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

11 
theory <name> 

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

15130  14 
begin 
15 

16234  16 
where the 'uses' part is optional. The previous syntax 
17 

18 
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 

17371  22 
nonIsar theories now, but these will disappear soon.

55 
Classical Reasoner. Typical big applications run around 2 times 

56 
faster. 

57 

17519  58 
* ProofGeneral interface: the default settings no longer prefer xemacs 
59 
over GNU emacs. Users typically need to experiment with various 

60 
variations on PROOFGENERAL_OPTIONS="... p emacs" to find the most 

61 
stable Emacs version on their platform.

* Commands 'display_drafts' and 'print_drafts' perform simple output 
67 
of raw sources. Only those symbols that do not require additional 

68 
LaTeX packages (depending on comments in isabellesym.sty) are 

69 
displayed properly, everything else is left verbatim. isatool display 

70

*** Pure *** 

139 

140 
* Considerably improved version of 'constdefs' command. Now performs 

141 
automatic typeinference of declared constants; additional support for 

142 
local structure declarations (cf. locales and HOL records), see also 

143 
isarref manual. Potential INCOMPATIBILITY: need to observe strictly 

144 
sequential dependencies of definitions within a single 'constdefs' 

145 
section; moreover, the declared name needs to be an identifier. If 

146 
all fails, consider to fall back on 'consts' and 'defs' separately. 

147 

148 
* Improved indexed syntax and implicit structures. First of all, 

149 
indexed syntax provides a notational device for subscripted 

150 
application, using the new syntax \<^bsub>term\<^esub> for arbitrary 

151 
expressions. Secondly, in a local context with structure 

152 
declarations, number indexes \<^sub>n or the empty index (default 

153 
number 1) refer to a certain fixed variable implicitly; option 

154 
show_structs controls printing of implicit structures. Typical 

155 
applications of these concepts involve record types and locales. 

156 

157 
* New command 'no_syntax' removes grammar declarations (and 

158 
translations) resulting from the given syntax specification, which is 

159 
interpreted in the same manner as for the 'syntax' command. 

160 

161 
* 'Advanced' translation functions (parse_translation etc.) may depend 

162 
on the signature of the theory context being presently used for 

163 
parsing/printing, see also isarref manual. 

164 

16856  165 
* Improved 'oracle' command provides a typesafe interface to turn an 
166 
ML expression of type theory > T > term into a primitive rule of 

167 
type theory > T > thm (i.e. the functionality of Thm.invoke_oracle 

168 
is already included here); see also FOL/ex/IffExample.thy;

16234  176 
* Improved internal renaming of symbolic identifiers  attach primes 
177 
instead of base 26 numbers. 

178 

179 
* New flag show_question_marks controls printing of leading question 

180 
marks in schematic variable names. 

181 

182 
* In schematic variable names, *any* symbol following \<^isub> or 

183 
\<^isup> is now treated as part of the base name. For example, the 

184 
following works without printing of awkward ".0" indexes: 

185 

186 
lemma "x\<^isub>1 = x\<^isub>2 ==> x\<^isub>2 = x\<^isub>1" 

187 
by simp 

188 

189 
* Inner syntax includes (*(*nested*) comments*). 

190 

191 
* Pretty pinter now supports unbreakable blocks, specified in mixfix 

192 
annotations as "(00...)". 

193 

194 
* Clear separation of logical types and nonterminals, where the latter 

195 
may only occur in 'syntax' specifications or type abbreviations. 

196 
Before that distinction was only partially implemented via type class 

197 
"logic" vs. "{}". Potential INCOMPATIBILITY in rare cases of improper 

198 
use of 'types'/'consts' instead of 'nonterminals'/'syntax'. Some very 

199 
exotic syntax specifications may require further adaption 

200 
(e.g. Cube/Base.thy). 

201 

202 
* Removed obsolete type class "logic", use the top sort {} instead. 

203 
Note that nonlogical types should be declared as 'nonterminals' 

204 
rather than 'types'. INCOMPATIBILITY for new objectlogic 

205 
specifications. 

206 

17535  207 
* 'defs': more wellformedness checks of overloaded definitions. 
208 

17095  209 
* Attributes 'induct' and 'cases': type or set names may now be 
210 
locally fixed variables as well. 

211 

16234  212 
* Simplifier: can now control the depth to which conditional rewriting 
213 
is traced via the PG menu Isabelle > Settings > Trace Simp Depth 

214 
Limit. 

215 

216 
* Simplifier: simplification procedures may now take the current 

217 
simpset into account (cf. Simplifier.simproc(_i) / mk_simproc 

218 
interface), which is very useful for calling the Simplifier

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

220 
is gone  use prems_of_ss on the simpset instead. Moreover, the 

221 
lowlevel mk_simproc no longer applies Logic.varify internally, to 

222 
allow for use in a context of fixed variables. 

223 

224 
* thin_tac now works even if the assumption being deleted contains !! 

225 
or ==>. More generally, erule now works even if the major premise of 

226 
the elimination rule contains !! or ==>. 

227 

228 
* Reorganized bootstrapping of the Pure theories; CPure is now derived 

229 
from Pure, which contains all common declarations already. Both 

230 
theories are defined via plain Isabelle/Isar .thy files. 

231 
INCOMPATIBILITY: elements of CPure (such as the CPure.intro / 

232 
CPure.elim / CPure.dest attributes) now appear in the Pure name space; 

233 
use isatool fixcpure to adapt your theory and ML sources.

236

*** Locales *** 

17095  249 

17385  250 
* New commands for the interpretation of locale expressions in 
251 
theories (1), locales (2) and proof contexts (3). These generate 

252 
proof obligations from the expression specification. After the 

253 
obligations have been discharged, theorems of the expression are added 

254 
to the theory, target locale or proof context. The synopsis of the 

255 
commands is a follows: 

256 

17095  257 
(1) interpretation expr inst 
258 
(2) interpretation target < expr 

259 
(3) interpret expr inst 

17385  260 

17095  261 
Interpretation in theories and proof contexts require a parameter 
262 
instantiation of terms from the current context. This is applied to 

17385  263 
specifications and theorems of the interpreted expression. 
264 
Interpretation in locales only permits parameter renaming through the 

265 
locale expression. Interpretation is smart in that interpretations 

266 
that are active already do not occur in proof obligations, neither are 

267 
instantiated theorems stored in duplicate. Use 'print_interps' to 

268 
inspect active interpretations of a particular locale. For details, 

17436  269 
see the Isar Reference manual. Examples can be found in 
270 
HOL/Finite_Set.thy and HOL/Algebra/UnivPoly.thy. 

16234  271 

272 
INCOMPATIBILITY: former 'instantiate' has been withdrawn, use 

273 
'interpret' instead. 

274 

17385  275 
* New context element 'constrains' for adding type constraints to 
276 
parameters. 

277 

278 
* Context expressions: renaming of parameters with syntax 

279 
redeclaration. 

17095  280 

281 
* Locale declaration: 'includes' disallowed. 

282 

16234  283 
* Proper static binding of attribute syntax  i.e. types / terms / 
284 
facts mentioned as arguments are always those of the locale definition 

285 
context, independently of the context of later invocations. Moreover, 

286 
locale operations (renaming and type / term instantiation) are applied 

287 
to attribute arguments as expected. 

288 

289 
INCOMPATIBILITY of the ML interface: always pass Attrib.src instead of 

290 
actual attributes; rare situations may require Attrib.attribute to 

291 
embed those attributes into Attrib.src that lack concrete syntax. 

292 
Attribute implementations need to cooperate properly with the static 

293 
binding mechanism. Basic parsers Args.XXX_typ/term/prop and 

294 
Attrib.XXX_thm etc. already do the right thing without further 

295 
intervention. Only unusual applications  such as "where" or "of" 

296 
(cf. src/Pure/Isar/attrib.ML), which process arguments depending both 

297 
on the context and the facts involved  may have to assign parsed 

298 
values to argument tokens explicitly. 

299 

300 
* Changed parameter management in theorem generation for long goal 

301 
statements with 'includes'. INCOMPATIBILITY: produces a different 

302 
theorem statement in rare situations. 

303 

17228  304 
* Locale inspection command 'print_locale' omits notes elements. Use 
305 
'print_locale!' to have them included in the output. 

306 

16234  307 

308 
*** Provers *** 

309 

310 
* Provers/hypsubst.ML: improved version of the subst method, for 

311 
singlestep rewriting: it now works in bound variable contexts. New is 

312 
'subst (asm)', for rewriting an assumption. INCOMPATIBILITY: may 

313 
rewrite a different subterm than the original subst method, which is 

314 
still available as 'simplesubst'. 

315 

316 
* Provers/quasi.ML: new transitivity reasoners for transitivity only 

317 
and quasi orders. 

318 

319 
* Provers/trancl.ML: new transitivity reasoner for transitive and 

320 
reflexivetransitive closure of relations. 

321 

322 
* Provers/blast.ML: new reference depth_limit to make blast's depth 

323 
limit (previously hardcoded with a value of 20) userdefinable. 

324 

325 
* Provers/simplifier.ML has been moved to Pure, where Simplifier.setup 

326 
is peformed already. Objectlogics merely need to finish their 

327 
initial simpset configuration as before. INCOMPATIBILITY.

334 
syntax (epsilon) 

335 
"_Eps" :: "[pttrn, bool] => 'a" ("(3\<some>_./ _)" [0, 10] 10) 

336 

16234  337 
The symbol \<some> is displayed as the alternative epsilon of LaTeX 
338 
and xsymbol; use option 'm epsilon' to get it actually printed. 

339 
Moreover, the mathematically important symbolic identifier \<epsilon> 

340 
becomes available as variable, constant etc. INCOMPATIBILITY, 

341 

342 
* "x > y" abbreviates "y < x" and "x >= y" abbreviates "y <= x". 

343 
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>" 

348 
instead of ":". 

349 

350 
* theory SetInterval: changed the syntax for open intervals: 

351 

352 
Old New 

353 
{..n(} {..<n} 

354 
{)n..} {n<..} 

355 
{m..n(} {m..<n} 

356 
{)m..n} {m<..n} 

357 
{)m..n(} {m<..<n} 

358 

359 
The old syntax is still supported but will disappear in the next 

360 
release. For conversion use the following Emacs search and replace 

361 
patterns (these are not perfect but work quite well): 

15046  362 

363 
{)\([^\.]*\)\.\. > {\1<\.\.} 

364 
\.\.\([^(}]*\)(} > \.\.<\1}

370 
* Theory Finite_Set: changed the syntax for 'setsum', summation over 
16234  371 
finite sets: "setsum (%x. e) A", which used to be "\<Sum>x:A. e", is 
17371  372 
now either "SUM x:A. e" or "\<Sum>x \<in> A. e". The bound variable can 
17189  373 
be a tuple pattern. 
16234  374 

375 
Some new syntax forms are available: 

376 

377 
"\<Sum>x  P. e" for "setsum (%x. e) {x. P}" 

378 
"\<Sum>x = a..b. e" for "setsum (%x. e) {a..b}" 

379 
"\<Sum>x = a..<b. e" for "setsum (%x. e) {a..<b}" 

380 
"\<Sum>x < k. e" for "setsum (%x. e) {..<k}" 

381 

382 
The latter form "\<Sum>x < k. e" used to be based on a separate 

383 
function "Summation", which has been discontinued. 

384 

385 
* theory Finite_Set: in structured induction proofs, the insert case 

386 
is now 'case (insert x F)' instead of the old counterintuitive 'case 

387 
(insert F x)'. 

388 

389 
* The 'refute' command has been extended to support a much larger 

390 
fragment of HOL, including axiomatic type classes, constdefs and 

391 
typedefs, inductive datatypes and recursion. 

392 

393 
* Datatype induction via method 'induct' now preserves the name of the 

394 
induction variable. For example, when proving P(xs::'a list) by 

395 
induction on xs, the induction step is now P(xs) ==> P(a#xs) rather 

396 
than P(list) ==> P(a#list) as previously. Potential INCOMPATIBILITY 

397 
in unstructured proof scripts. 

398 

399 
* Reworked implementation of records. Improved scalability for 

400 
records with many fields, avoiding performance problems for type 

401 
inference. Records are no longer composed of nested field types, but 

402 
of nested extension types. Therefore the record type only grows linear 

403 
in the number of extensions and not in the number of fields. The 

404 
toplevel (users) view on records is preserved. Potential 

405 
INCOMPATIBILITY only in strange cases, where the theory depends on the 

406 
old record representation. The type generated for a record is called 

407 
<record_name>_ext_type. 

408 

409 
Flag record_quick_and_dirty_sensitive can be enabled to skip the 

410 
proofs triggered by a record definition or a simproc (if 

411 
quick_and_dirty is enabled). Definitions of large records can take 

412 
quite long. 

413 

414 
New simproc record_upd_simproc for simplification of multiple record 

415 
updates enabled by default. Moreover, trivial updates are also 

416 
removed: r(x := x r) = r. INCOMPATIBILITY: old proofs break 

417 
occasionally, since simplification is more powerful by default.

* Simplifier: automatically reasons about transitivity chains 
423

424 
provided by Provers/trancl.ML as additional solvers. INCOMPATIBILITY: 

425 
old proofs break occasionally as simplification may now solve more 

426 
goals than previously. 

427 

428 
* Simplifier: converts x <= y into x = y if assumption y <= x is 

429 
present. Works for all partial orders (class "order"), in particular 

430 
numbers and sets. For linear orders (e.g. numbers) it treats ~ x < y 

431 
just like y <= x. 

432 

433 
* Simplifier: new simproc for "let x = a in f x". If a is a free or 

434 
bound variable or a constant then the let is unfolded. Otherwise 

435 
first a is simplified to b, and then f b is simplified to g. If 

436 
possible we abstract b from g arriving at "let x = b in h x", 

437 
otherwise we unfold the let and arrive at g. The simproc can be 

438 
enabled/disabled by the reference use_let_simproc. Potential 

439 
INCOMPATIBILITY since simplification is more powerful by default.

matching; defining multiple functions with mutual recursion is also 

666 
supported. Patterns may include the constants cpair, spair, up, sinl, 

667

668 
equations are proven as rewrite rules. See HOLCF/ex/Fixrec_ex.thy for 

669 
syntax and examples.

* New commands 'cpodef' and 'pcpodef' for defining predicate subtypes 

672 
of cpo and pcpo types. Syntax is exactly like the 'typedef' command, 

673

Sign.declare_name. Several theory and proof context operations modify 

824 
the naming context. Especially note Theory.restore_naming and 

825 
ProofContext.restore_naming to get back to a sane state; note that 

826 
Theory.add_path is no longer sufficient to recover from 

827 
Theory.absolute_path in particular.

* Pure: new flags short_names (default false) and unique_names 

830

831 
short_names is set, names are printed unqualified. If unique_names is 

832 
reset, the name prefix is reduced to the minimum required to achieve 

833 
the original result when interning again, even if there is an overlap 

834 
with earlier declarations.

* Pure: Greek letters (except small lambda, \<lambda>), as well as Gothic 
977 
(\<aa>...\<zz>\<AA>...\<ZZ>), calligraphic (\<A>...\<Z>), and Euler 

14173  978 
(\<a>...\<z>), are now considered normal letters, and can therefore 
979 
be used anywhere where an ASCII letter (a...zA...Z) has until 

980 
now. COMPATIBILITY: This obviously changes the parsing of some 

981 
terms, especially where a symbol has been used as a binder, say 

982 
'\<Pi>x. ...', which is now a type error since \<Pi>x will be parsed 

983 
as an identifier. Fix it by inserting a space around former 

984 
symbols. Call 'isatool fixgreek' to try to fix parsing errors in 

985 
existing theory and ML files.

1086 
* Numerics: 

1087 
 Numeric types (nat, int, and in HOLComplex rat, real, complex, etc.) are 

14731  1088 
now formalized using the Ring_and_Field theory mentioned above. 
14389  1089 
 INCOMPATIBILITY: simplification and arithmetic behaves somewhat differently 
1090 
than before, because now they are set up once in a generic manner. 

14731  1091 
 INCOMPATIBILITY: many typespecific arithmetic laws have gone.

1093 
exponentiation).

1100 
the reference "print_record_type_abbr".

* Unions and Intersections: 
15119  1122 
The latex output syntax of UN and INT has been changed 
1123 
from "\Union x \in A. B" to "\Union_{x \in A} B" 

1124 
i.e. the index formulae has become a subscript. 

1125 
Similarly for "\Union x. B", and for \Inter instead of \Union. 

14380  1126 

14418  1127 
* Unions and Intersections over Intervals: 
14731  1128 
There is new short syntax "UN i<=n. A" for "UN i:{0..n}. A". There is 
1129 
also an xsymbol version with subscripts "\<Union>\<^bsub>i <= n\<^esub>. A" 

14418  1130 
like in normal math, and corresponding versions for < and for intersection. 
1131 

15677  1132

1133 
lexicographic dictonary ordering has been added as "lexord". 

1134

* ML: the legacy theory structures Int and List have been removed. They had 
1136 
conflicted with ML Basis Library structures having the same names. 

14380  1137 

14464  1138 
* 'refute' command added to search for (finite) countermodels. Only works 
1139 
for a fragment of HOL. The installation of an external SAT solver is 

1140 
highly recommended. See "HOL/Refute.thy" for details. 

1141 

14602  1142 
* 'quickcheck' command: Allows to find counterexamples by evaluating 
1143 
formulae under an assignment of free variables to random values. 

1144 
In contrast to 'refute', it can deal with inductive datatypes, 

1145 
but cannot handle quantifiers. See "HOL/ex/Quickcheck_Examples.thy"

 simp sometimes diverges where the old version did 
1170 
not, e.g. invoking simp on the goal 

13618  1171 

1172 
[ P (f x); y = x; f x = f y ] ==> Q 

1173 

13781  1174 
now gives rise to the infinite reduction sequence 
1175 

1176 
P(f x) (f x = f y)> P(f y) (y = x)> P(f x) (f x = f y)> ... 

1177 

1178 
Using "simp (asm_lr)" (ML: Asm_lr_simp_tac) instead often solves this 

1179 
kind of problem. 

1180 

1181 
 Tactics combining classical reasoner and simplification (such as auto) 

1182 
are also affected by this change, because many of them rely on 

1183 
simp. They may sometimes diverge as well or yield a different numbers 

1184 
of subgoals. Try to use e.g. force, fastsimp, or safe instead of auto 

1185 
in case of problems. Sometimes subsequent calls to the classical 

1186 
reasoner will fail because a preceeding call to the simplifier too 

1187 
eagerly simplified the goal, e.g. deleted redundant premises. 

13618  1188 

1189 
 The simplifier trace now shows the names of the applied rewrite rules 

1190 

13829  1191 
 You can limit the number of recursive invocations of the simplifier 
1192 
during conditional rewriting (where the simplifie tries to solve the 

1193 
conditions before applying the rewrite rule): 

1194 
ML "simp_depth_limit := n" 

1195 
where n is an integer. Thus you can force termination where previously 

1196 
the simplifier would diverge.
