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

11 
theory <name> 

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

begin 
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 

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

53 
Classical Reasoner. Typical big applications run around 2 times

* ProofGeneral interface: the default settings no longer prefer xemacs 
57

58 
variations on PROOFGENERAL_OPTIONS="... p emacs" to find the most 

59 
stable Emacs version on their platform.

* Commands 'display_drafts' and 'print_drafts' perform simple output 
65

66 
LaTeX packages (depending on comments in isabellesym.sty) are 

67 
displayed properly, everything else is left verbatim. isatool display 

68

*** Pure *** 

137 

138 
* Considerably improved version of 'constdefs' command. Now performs 

139 
automatic typeinference of declared constants; additional support for 

140 
local structure declarations (cf. locales and HOL records), see also 

141 
isarref manual. Potential INCOMPATIBILITY: need to observe strictly 

142 
sequential dependencies of definitions within a single 'constdefs' 

143 
section; moreover, the declared name needs to be an identifier. If 

144 
all fails, consider to fall back on 'consts' and 'defs' separately. 

145 

146 
* Improved indexed syntax and implicit structures. First of all, 

147 
indexed syntax provides a notational device for subscripted 

148 
application, using the new syntax \<^bsub>term\<^esub> for arbitrary 

149 
expressions. Secondly, in a local context with structure 

150 
declarations, number indexes \<^sub>n or the empty index (default 

151 
number 1) refer to a certain fixed variable implicitly; option 

152 
show_structs controls printing of implicit structures. Typical 

153 
applications of these concepts involve record types and locales. 

154 

155 
* New command 'no_syntax' removes grammar declarations (and 

156 
translations) resulting from the given syntax specification, which is 

157 
interpreted in the same manner as for the 'syntax' command. 

158 

159 
* 'Advanced' translation functions (parse_translation etc.) may depend 

160 
on the signature of the theory context being presently used for 

161 
parsing/printing, see also isarref manual. 

162 

16856  163 
* Improved 'oracle' command provides a typesafe interface to turn an 
164 
ML expression of type theory > T > term into a primitive rule of 

165 
type theory > T > thm (i.e. the functionality of Thm.invoke_oracle 

166 
is already included here); see also FOL/ex/IffExample.thy;

* Improved internal renaming of symbolic identifiers  attach primes 
175 
instead of base 26 numbers. 

176 

177 
* New flag show_question_marks controls printing of leading question 

178 
marks in schematic variable names. 

179 

180 
* In schematic variable names, *any* symbol following \<^isub> or 

181 
\<^isup> is now treated as part of the base name. For example, the 

182 
following works without printing of awkward ".0" indexes: 

183 

184 
lemma "x\<^isub>1 = x\<^isub>2 ==> x\<^isub>2 = x\<^isub>1" 

185 
by simp 

186 

187 
* Inner syntax includes (*(*nested*) comments*). 

188 

189 
* Pretty pinter now supports unbreakable blocks, specified in mixfix 

190 
annotations as "(00...)". 

191 

192 
* Clear separation of logical types and nonterminals, where the latter 

193 
may only occur in 'syntax' specifications or type abbreviations. 

194 
Before that distinction was only partially implemented via type class 

195 
"logic" vs. "{}". Potential INCOMPATIBILITY in rare cases of improper 

196 
use of 'types'/'consts' instead of 'nonterminals'/'syntax'. Some very 

197 
exotic syntax specifications may require further adaption 

198 
(e.g. Cube/Base.thy). 

199 

200 
* Removed obsolete type class "logic", use the top sort {} instead. 

201 
Note that nonlogical types should be declared as 'nonterminals' 

202 
rather than 'types'. INCOMPATIBILITY for new objectlogic 

203 
specifications. 

204 

17535  205 
* 'defs': more wellformedness checks of overloaded definitions. 
206 

17095  207 
* Attributes 'induct' and 'cases': type or set names may now be 
208 
locally fixed variables as well. 

209 

16234  210 
* Simplifier: can now control the depth to which conditional rewriting 
211 
is traced via the PG menu Isabelle > Settings > Trace Simp Depth 

212 
Limit. 

213 

214 
* Simplifier: simplification procedures may now take the current 

215 
simpset into account (cf. Simplifier.simproc(_i) / mk_simproc 

216 
interface), which is very useful for calling the Simplifier 

217 
recursively. Minor INCOMPATIBILITY: the 'prems' argument of simprocs 

218 
is gone  use prems_of_ss on the simpset instead. Moreover, the

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

223 
or ==>. More generally, erule now works even if the major premise of 

224

225 

226 
* Reorganized bootstrapping of the Pure theories; CPure is now derived 

227 
from Pure, which contains all common declarations already. Both 

228 
theories are defined via plain Isabelle/Isar .thy files. 

229 
INCOMPATIBILITY: elements of CPure (such as the CPure.intro / 

230 
CPure.elim / CPure.dest attributes) now appear in the Pure name space; 

231 
use isatool fixcpure to adapt your theory and ML sources.

*** Locales *** 

17095  247 

17385  248 
* New commands for the interpretation of locale expressions in 
249 
theories (1), locales (2) and proof contexts (3). These generate 

250 
proof obligations from the expression specification. After the 

251 
obligations have been discharged, theorems of the expression are added 

252 
to the theory, target locale or proof context. The synopsis of the 

253 
commands is a follows: 

254 

17095  255 
(1) interpretation expr inst 
256 
(2) interpretation target < expr 

257 
(3) interpret expr inst 

17385  258 

17095  259 
Interpretation in theories and proof contexts require a parameter 
260 
instantiation of terms from the current context. This is applied to 

17385  261 
specifications and theorems of the interpreted expression. 
262 
Interpretation in locales only permits parameter renaming through the 

263 
locale expression. Interpretation is smart in that interpretations 

264 
that are active already do not occur in proof obligations, neither are 

265 
instantiated theorems stored in duplicate. Use 'print_interps' to 

266 
inspect active interpretations of a particular locale. For details, 

17436  267 
see the Isar Reference manual. Examples can be found in 
268 
HOL/Finite_Set.thy and HOL/Algebra/UnivPoly.thy. 

16234  269 

270 
INCOMPATIBILITY: former 'instantiate' has been withdrawn, use 

271 
'interpret' instead. 

272 

17385  273 
* New context element 'constrains' for adding type constraints to 
274 
parameters. 

275 

276 
* Context expressions: renaming of parameters with syntax 

277 
redeclaration. 

17095  278 

279 
* Locale declaration: 'includes' disallowed. 

280 

16234  281 
* Proper static binding of attribute syntax  i.e. types / terms / 
282 
facts mentioned as arguments are always those of the locale definition 

283 
context, independently of the context of later invocations. Moreover, 

284 
locale operations (renaming and type / term instantiation) are applied 

285 
to attribute arguments as expected. 

286 

287 
INCOMPATIBILITY of the ML interface: always pass Attrib.src instead of 

288 
actual attributes; rare situations may require Attrib.attribute to 

289 
embed those attributes into Attrib.src that lack concrete syntax. 

290 
Attribute implementations need to cooperate properly with the static 

291 
binding mechanism. Basic parsers Args.XXX_typ/term/prop and 

292 
Attrib.XXX_thm etc. already do the right thing without further 

293 
intervention. Only unusual applications  such as "where" or "of" 

294 
(cf. src/Pure/Isar/attrib.ML), which process arguments depending both 

295 
on the context and the facts involved  may have to assign parsed 

296 
values to argument tokens explicitly. 

297 

298 
* Changed parameter management in theorem generation for long goal 

299 
statements with 'includes'. INCOMPATIBILITY: produces a different 

300 
theorem statement in rare situations. 

301 

17228  302 
* Locale inspection command 'print_locale' omits notes elements. Use 
303 
'print_locale!' to have them included in the output. 

304 

16234  305 

306 
*** Provers *** 

307 

308 
* Provers/hypsubst.ML: improved version of the subst method, for 

309 
singlestep rewriting: it now works in bound variable contexts. New is 

310 
'subst (asm)', for rewriting an assumption. INCOMPATIBILITY: may 

311 
rewrite a different subterm than the original subst method, which is 

312 
still available as 'simplesubst'. 

313 

314 
* Provers/quasi.ML: new transitivity reasoners for transitivity only 

315 
and quasi orders. 

316 

317 
* Provers/trancl.ML: new transitivity reasoner for transitive and 

318 
reflexivetransitive closure of relations. 

319 

320 
* Provers/blast.ML: new reference depth_limit to make blast's depth 

321 
limit (previously hardcoded with a value of 20) userdefinable. 

322 

323 
* Provers/simplifier.ML has been moved to Pure, where Simplifier.setup 

324 
is peformed already. Objectlogics merely need to finish their 

325 
initial simpset configuration as before. INCOMPATIBILITY.

332

333 
"_Eps" :: "[pttrn, bool] => 'a" ("(3\<some>_./ _)" [0, 10] 10) 

334 

16234  335 
The symbol \<some> is displayed as the alternative epsilon of LaTeX 
336 
and xsymbol; use option 'm epsilon' to get it actually printed. 

337 
Moreover, the mathematically important symbolic identifier \<epsilon> 

338 
becomes available as variable, constant etc. INCOMPATIBILITY, 

339 

340 
* "x > y" abbreviates "y < x" and "x >= y" abbreviates "y <= x". 

341 
Similarly for all quantifiers: "ALL x > y" etc. The xsymbol for >=

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

instead of ":". 

347 

348 
* theory SetInterval: changed the syntax for open intervals: 

349 

350 
Old New 

351 
{..n(} {..<n} 

352 
{)n..} {n<..} 

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

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

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

356 

357 
The old syntax is still supported but will disappear in the next 

358 
release. For conversion use the following Emacs search and replace 

359 
patterns (these are not perfect but work quite well): 

15046  360 

361 
{)\([^\.]*\)\.\. > {\1<\.\.} 

362 
\.\.\([^(}]*\)(} > \.\.<\1}

368 
* Theory Finite_Set: changed the syntax for 'setsum', summation over 
16234  369 
finite sets: "setsum (%x. e) A", which used to be "\<Sum>x:A. e", is 
17371  370 
now either "SUM x:A. e" or "\<Sum>x \<in> A. e". The bound variable can 
17189  371 
be a tuple pattern. 
16234  372 

373 
Some new syntax forms are available: 

374 

375 
"\<Sum>x  P. e" for "setsum (%x. e) {x. P}" 

376 
"\<Sum>x = a..b. e" for "setsum (%x. e) {a..b}" 

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

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

379 

380 
The latter form "\<Sum>x < k. e" used to be based on a separate 

381 
function "Summation", which has been discontinued. 

382 

383 
* theory Finite_Set: in structured induction proofs, the insert case 

384 
is now 'case (insert x F)' instead of the old counterintuitive 'case 

385 
(insert F x)'. 

386 

387 
* The 'refute' command has been extended to support a much larger 

388 
fragment of HOL, including axiomatic type classes, constdefs and 

389 
typedefs, inductive datatypes and recursion. 

390 

391 
* Datatype induction via method 'induct' now preserves the name of the 

392 
induction variable. For example, when proving P(xs::'a list) by 

393 
induction on xs, the induction step is now P(xs) ==> P(a#xs) rather 

394 
than P(list) ==> P(a#list) as previously. Potential INCOMPATIBILITY 

395 
in unstructured proof scripts. 

396 

397 
* Reworked implementation of records. Improved scalability for 

398 
records with many fields, avoiding performance problems for type 

399 
inference. Records are no longer composed of nested field types, but 

400 
of nested extension types. Therefore the record type only grows linear 

401 
in the number of extensions and not in the number of fields. The 

402 
toplevel (users) view on records is preserved. Potential 

403 
INCOMPATIBILITY only in strange cases, where the theory depends on the 

404 
old record representation. The type generated for a record is called 

405 
<record_name>_ext_type. 

406 

407 
Flag record_quick_and_dirty_sensitive can be enabled to skip the 

408 
proofs triggered by a record definition or a simproc (if 

409 
quick_and_dirty is enabled). Definitions of large records can take 

410 
quite long. 

411 

412 
New simproc record_upd_simproc for simplification of multiple record 

413 
updates enabled by default. Moreover, trivial updates are also 

414 
removed: r(x := x r) = r. INCOMPATIBILITY: old proofs break 

415 
occasionally, since simplification is more powerful by default.

421

422 
provided by Provers/trancl.ML as additional solvers. INCOMPATIBILITY: 

423 
old proofs break occasionally as simplification may now solve more 

424 
goals than previously. 

425 

426 
* Simplifier: converts x <= y into x = y if assumption y <= x is 

427 
present. Works for all partial orders (class "order"), in particular 

428 
numbers and sets. For linear orders (e.g. numbers) it treats ~ x < y 

429 
just like y <= x. 

430 

431 
* Simplifier: new simproc for "let x = a in f x". If a is a free or 

432 
bound variable or a constant then the let is unfolded. Otherwise 

433 
first a is simplified to b, and then f b is simplified to g. If 

434 
possible we abstract b from g arriving at "let x = b in h x", 

435 
otherwise we unfold the let and arrive at g. The simproc can be 

436 
enabled/disabled by the reference use_let_simproc. Potential 

437 
INCOMPATIBILITY since simplification is more powerful by default.

663 
matching; defining multiple functions with mutual recursion is also 

664 
supported. Patterns may include the constants cpair, spair, up, sinl, 

665 
sinr, or any data constructor defined by the domain package. The given 

666 
equations are proven as rewrite rules. See HOLCF/ex/Fixrec_ex.thy for 

667 
syntax and examples. 

668

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

670 
of cpo and pcpo types. Syntax is exactly like the 'typedef' command, 

671 
but the proof obligation additionally includes an admissibility

819 
a fully qualified name and external accesses of a fully qualified 

820

Sign.declare_name. Several theory and proof context operations modify 

822 
the naming context. Especially note Theory.restore_naming and 

823 
ProofContext.restore_naming to get back to a sane state; note that 

824 
Theory.add_path is no longer sufficient to recover from 

825 
Theory.absolute_path in particular.

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

828 
(default true) for controlling output of qualified names. If 

829 
short_names is set, names are printed unqualified. If unique_names is 

830 
reset, the name prefix is reduced to the minimum required to achieve 

831 
the original result when interning again, even if there is an overlap 

832 
with earlier declarations.

* Pure: Greek letters (except small lambda, \<lambda>), as well as Gothic 
974 
(\<aa>...\<zz>\<AA>...\<ZZ>), calligraphic (\<A>...\<Z>), and Euler 

14173  975 
(\<a>...\<z>), are now considered normal letters, and can therefore 
976 
be used anywhere where an ASCII letter (a...zA...Z) has until 

977 
now. COMPATIBILITY: This obviously changes the parsing of some 

978 
terms, especially where a symbol has been used as a binder, say 

979 
'\<Pi>x. ...', which is now a type error since \<Pi>x will be parsed 

980 
as an identifier. Fix it by inserting a space around former 

981 
symbols. Call 'isatool fixgreek' to try to fix parsing errors in 

982 
existing theory and ML files.

1084 
 Numeric types (nat, int, and in HOLComplex rat, real, complex, etc.) are 

14731  1085 
now formalized using the Ring_and_Field theory mentioned above. 
14389  1086 
 INCOMPATIBILITY: simplification and arithmetic behaves somewhat differently

* Unions and Intersections: 
15119  1119 
The latex output syntax of UN and INT has been changed 
1120 
from "\Union x \in A. B" to "\Union_{x \in A} B" 

1121 
i.e. the index formulae has become a subscript. 

1122 
Similarly for "\Union x. B", and for \Inter instead of \Union. 

14380  1123 

14418  1124 
* Unions and Intersections over Intervals: 
14731  1125 
There is new short syntax "UN i<=n. A" for "UN i:{0..n}. A". There is 
1126 
also an xsymbol version with subscripts "\<Union>\<^bsub>i <= n\<^esub>. A" 

14418  1127 
like in normal math, and corresponding versions for < and for intersection. 
1128

* ML: the legacy theory structures Int and List have been removed. They had 
1133 
conflicted with ML Basis Library structures having the same names. 

14380  1134 

14464  1135 
* 'refute' command added to search for (finite) countermodels. Only works 
1136 
for a fragment of HOL. The installation of an external SAT solver is 

1137 
highly recommended. See "HOL/Refute.thy" for details. 

1138 

14602  1139 
* 'quickcheck' command: Allows to find counterexamples by evaluating 
1140 
formulae under an assignment of free variables to random values. 

1141 
In contrast to 'refute', it can deal with inductive datatypes, 

1142 
but cannot handle quantifiers. See "HOL/ex/Quickcheck_Examples.thy"

now gives rise to the infinite reduction sequence 
1172 

1173 
P(f x) (f x = f y)> P(f y) (y = x)> P(f x) (f x = f y)> ... 

1174 

1175 
Using "simp (asm_lr)" (ML: Asm_lr_simp_tac) instead often solves this 

1176 
kind of problem. 

1177 

1178 
 Tactics combining classical reasoner and simplification (such as auto) 

1179 
are also affected by this change, because many of them rely on 

1180 
simp. They may sometimes diverge as well or yield a different numbers 

1181 
of subgoals. Try to use e.g. force, fastsimp, or safe instead of auto 

1182 
in case of problems. Sometimes subsequent calls to the classical 

1183 
reasoner will fail because a preceeding call to the simplifier too 

1184 
eagerly simplified the goal, e.g. deleted redundant premises. 

13618  1185 

1186 
 The simplifier trace now shows the names of the applied rewrite rules 

1187 

13829  1188 
 You can limit the number of recursive invocations of the simplifier 
1189 
during conditional rewriting (where the simplifie tries to solve the 

1190 
conditions before applying the rewrite rule): 

1191 
ML "simp_depth_limit := n" 

1192 
where n is an integer. Thus you can force termination where previously 

1193 
the simplifier would diverge.
