*** General *** 
11 

63273  12 
* Command 'bundle' provides a local theory target to define a bundle 
13 
from the body of specification commands (such as 'declare', 

14 
'declaration', 'notation', 'lemmas', 'lemma'). For example: 

15 

16 
bundle foo 

17 
begin 

18 
declare a [simp] 

19 
declare b [intro] 

20 
end 

63272  21 

63282  22 
* Command 'unbundle' is like 'include', but works within a local theory 
23 
context. Unlike "context includes ... begin", the effect of 'unbundle' 

24 
on the target context persists, until different declarations are given. 

25 

63977  26 
* Simplified outer syntax: uniform category "name" includes long 
27 
identifiers. Former "xname" / "nameref" / "name reference" has been 

28 
discontinued. 

29 

30 
* Embedded content (e.g. the inner syntax of types, terms, props) may be 

31 
delimited uniformly via cartouches. This works better than oldfashioned 

32 
quotes when sublanguages are nested. 

33 

34 
* Mixfix annotations support general block properties, with syntax 

35 
"(\<open>x=a y=b z \<dots>\<close>". Notable property names are "indent", "consistent", 

36 
"unbreakable", "markup". The existing notation "(DIGITS" is equivalent 

37 
to "(\<open>indent=DIGITS\<close>". The former notation "(00" for unbreakable blocks 

38 
is superseded by "(\<open>unbreabable\<close>"  rare INCOMPATIBILITY. 

63650  39 

63383  40 
* Proof method "blast" is more robust wrt. corner cases of Pure 
41 
statements without objectlogic judgment. 

42 

63624

43 
* Commands 'prf' and 'full_prf' are somewhat more informative (again): 
63977  44 
proof terms are reconstructed and cleaned from administrative thm nodes. 
45 

46 
* Code generator: config option "code_timing" triggers measurements of 

47 
different phases of code generation. See src/HOL/ex/Code_Timing.thy for 

48 
examples. 

49 

50 
* Code generator: implicits in Scala (stemming from type class 

51 
instances) are generated into companion object of corresponding type 

52 
class, to resolve some situations where ambiguities may occur. 

53 

54 
* Splitter in simp, auto and friends: 

55 
 The syntax "split add" has been discontinued, use plain "split", 

56 
INCOMPATIBILITY. 

57 
 For situations with many conditional or case expressions, there is 

58 
an alternative splitting strategy that can be much faster. It is 

59 
selected by writing "split!" instead of "split". It applies safe 

60 
introduction and elimination rules after each split rule. As a 

61 
result the subgoal may be split into several subgoals.

*** Prover IDE  Isabelle/Scala/jEdit *** 
68 

63977  69 
* Highlighting of entity def/ref positions wrt. cursor. 
70 

71 
* Action "isabelle.selectentity" (shortcut CS+ENTER) selects all 

72 
occurences of the formal entity at the caret position. This facilitates 

73 
systematic renaming. 

74 

75 
* PIDE document markup works across multiple Isar commands, e.g. the 

76 
results established at the end of a proof are properly identified in the 

77 
theorem statement. 

78 

79 
* Cartouche abbreviations work both for " and ` to accomodate typical 

80 
situations where old ASCII notation may be updated. 

81 

63875  82 
* Dockable window "Symbols" also provides access to 'abbrevs' from the 
83 
outer syntax of the current theory buffer. This provides clickable 

84 
syntax templates, including entries with empty abbrevs name (which are 

85 
inaccessible via keyboard completion). 

86 

63022  87 
* IDE support for the Isabelle/Pure bootstrap process, with the 
88 
following independent stages: 

89 

90 
src/Pure/ROOT0.ML 

91 
src/Pure/ROOT.ML 

92 
src/Pure/Pure.thy 

93 
src/Pure/ML_Bootstrap.thy 

94 

95 
The ML ROOT files act like quasitheories in the context of theory 

96 
ML_Bootstrap: this allows continuous checking of all loaded ML files. 

97 
The theory files are presented with a modified header to import Pure 

98 
from the running Isabelle instance. Results from changed versions of 

99 
each stage are *not* propagated to the next stage, and isolated from the 

100 
actual Isabelle/Pure that runs the IDE itself. The sequential 

63307  101 
dependencies of the above files are only observed for batch build. 
62904  102 

63977  103 
* Isabelle/ML and Standard ML files are presented in Sidekick with the 
104 
tree structure of section headings: this special comment format is 

105 
described in "implementation" chapter 0, e.g. (*** section ***). 

63461  106 

63608  107 
* Sidekick parser "isabellecontext" shows nesting of context blocks 
108 
according to 'begin' and 'end' structure.

63977  123 
* Refined folding mode "isabelle" based on Isar syntax: 'next' and 'qed' 
124 
are treated as delimiters for fold structure; 'begin' and 'end' 

125 
structure of theory specifications is treated as well. 

63236  126 

63751  127 
* Action "isabelle.keymapmerge" asks the user to resolve pending 
128 
Isabelle keymap changes that are in conflict with the current jEdit 

129 
keymap; nonconflicting changes are always applied implicitly. This 

130 
action is automatically invoked on Isabelle/jEdit startup and thus 

131 
increases chances that users see new keyboard shortcuts when reusing 

132 
old keymaps.

139 

63581  140 
* Additional abbreviations for syntactic completion may be specified 
63871  141 
within the theory header as 'abbrevs'. The theory syntax for 'keywords' 
142 
has been simplified accordingly: optional abbrevs need to go into the 

143 
new 'abbrevs' section. 

144 

145 
* Global abbreviations via $ISABELLE_HOME/etc/abbrevs and 

146 
$ISABELLE_HOME_USER/etc/abbrevs are no longer supported. Minor 

147 
INCOMPATIBILITY, use 'abbrevs' within theory header instead. 

63579  148 

63675  149 
* ML and document antiquotations for filesystems paths are more uniform 
150 
and diverse: 

151 

152 
@{path NAME}  no filesystem check 

153 
@{file NAME}  check for plain file 

154 
@{dir NAME}  check for directory 

155 

156 
Minor INCOMPATIBILITY, former uses of @{file} and @{file_unchecked} may 

157 
have to be changed. 

63669  158

63977  160 
*** Document preparation *** 
161 

162 
* New symbol \<circle>, e.g. for temporal operator. 

163 

64073  164 
* New document and ML antiquotation @{locale} for locales, similar to 
165 
existing antiquotation @{class}. 

166 

63977  167 
* Mixfix annotations support delimiters like \<^control>\<open>cartouche\<close>  
168 
this allows special forms of document output. 

169 

170 
* Raw LaTeX output now works via \<^latex>\<open>...\<close> instead of raw control 

171 
symbol \<^raw:...>. INCOMPATIBILITY, notably for LaTeXsugar.thy and its 

172 
derivatives. 

173 

174 
* \<^raw:...> symbols are no longer supported. 

175 

176 
* Old 'header' command is no longer supported (legacy since 

177 
Isabelle2015).

* Command 'define' introduces a local (nonpolymorphic) definition, with 
193 
optional abstraction over local parameters. The syntax resembles 

63043  194 
'definition' and 'obtain'. It fits better into the Isar language than 
195 
old 'def', which is now a legacy feature.

62216  202 

63977  203 
* The defining position of a literal fact \<open>prop\<close> is maintained more 
204 
carefully, and made accessible as hyperlink in the Prover IDE. 

205 

206 
* Commands 'finally' and 'ultimately' used to expose the result as 

207 
literal fact: this accidental behaviour has been discontinued. Rare 

208 
INCOMPATIBILITY, use more explicit means to refer to facts in Isar. 

209 

210 
* Command 'axiomatization' has become more restrictive to correspond 

211 
better to internal axioms as singleton facts with mandatory name. Minor 

212 
INCOMPATIBILITY. 

62939  213 

63259  214 
* Proof methods may refer to the main facts via the dynamic fact 
215 
"method_facts". This is particularly useful for Eisbach method 

216 
definitions. 

217 

63527  218 
* Proof method "use" allows to modify the main facts of a given method 
219 
expression, e.g. 

63259  220 

221 
(use facts in simp) 

222 
(use facts in \<open>simp add: ...\<close>) 

223 

63977  224 
* The old proof method "default" has been removed (legacy since 
225 
Isabelle2016). INCOMPATIBILITY, use "standard" instead.

229 

63977  230 
* Pure provides basic versions of proof methods "simp" and "simp_all" 
231 
that only know about metaequality (==). Potential INCOMPATIBILITY in 

232 
theory imports that merge Pure with e.g. Main of Isabelle/HOL: the order 

233 
is relevant to avoid confusion of Pure.simp vs. HOL.simp. 

234 

235 
* The command 'unfolding' and proof method "unfold" include a second 

236 
stage where given equations are passed through the attribute "abs_def" 

237 
before rewriting. This ensures that definitions are fully expanded, 

238 
regardless of the actual parameters that are provided. Rare 

239 
INCOMPATIBILITY in some corner cases: use proof method (simp only:) 

240 
instead, or declare [[unfold_abs_def = false]] in the proof context. 

241 

242 
* Typeinference improves sorts of newly introduced type variables for 

243 
the objectlogic, using its base sort (i.e. HOL.type for Isabelle/HOL). 

244 
Thus terms like "f x" or "\<And>x. P x" without any further syntactic context 

245 
produce x::'a::type in HOL instead of x::'a::{} in Pure. Rare 

246 
INCOMPATIBILITY, need to provide explicit type constraints for Pure 

247 
types where this is really intended.

327 
 The "size" plugin has been made compatible again with locales. 
63855  328 
 The theorems about "rel" and "set" may have a slightly different (but 
329 
equivalent) form. 

330 
INCOMPATIBILITY. 

62327  331 

63977  332 
* The 'coinductive' command produces a proper coinduction rule for 
333 
mutual coinductive predicates. This new rule replaces the old rule, 

334 
which exposed details of the internal fixpoint construction and was 

335 
hard to use. INCOMPATIBILITY. 

336 

337 
* New abbreviations for negated existence (but not bounded existence): 

338 

339 
\<nexists>x. P x \<equiv> \<not> (\<exists>x. P x) 

340 
\<nexists>!x. P x \<equiv> \<not> (\<exists>!x. P x) 

341 

342 
* The print mode "HOL" for ASCII syntax of binders "!", "?", "?!", "@" 

343 
has been removed for output. It is retained for input only, until it is 

344 
eliminated altogether. 

345 

346 
* The unique existence quantifier no longer provides 'binder' syntax, 

347 
but uses syntax translations (as for bounded unique existence). Thus 

348 
iterated quantification \<exists>!x y. P x y with its slightly confusing 

349 
sequential meaning \<exists>!x. \<exists>!y. P x y is no longer possible. Instead, 

350 
pattern abstraction admits simultaneous unique existence \<exists>!(x, y). P x y 

351 
(analogous to existing notation \<exists>!(x, y)\<in>A. P x y). Potential 

352 
INCOMPATIBILITY in rare situations. 

353 

354 
* Conventional syntax "%(). t" for unit abstractions. Slight syntactic 

355 
INCOMPATIBILITY. 

356 

357 
* Characters (type char) are modelled as finite algebraic type 

358 
corresponding to {0..255}. 

359 

360 
 Logical representation: 

361 
* 0 is instantiated to the ASCII zero character. 

362 
* All other characters are represented as "Char n" 

363 
with n being a raw numeral expression less than 256. 

364 
* Expressions of the form "Char n" with n greater than 255 

365 
are noncanonical. 

366 
 Printing and parsing: 

367 
* Printable characters are printed and parsed as "CHR ''\<dots>''" 

368 
(as before). 

369 
* The ASCII zero character is printed and parsed as "0". 

370 
* All other canonical characters are printed as "CHR 0xXX" 

371 
with XX being the hexadecimal character code. "CHR n" 

372 
is parsable for every numeral expression n. 

373 
* Noncanonical characters have no special syntax and are 

374 
printed as their logical representation. 

375 
 Explicit conversions from and to the natural numbers are 

376 
provided as char_of_nat, nat_of_char (as before). 

377 
 The auxiliary nibble type has been discontinued. 

378 

379 
INCOMPATIBILITY. 

380 

381 
* Type class "div" with operation "mod" renamed to type class "modulo" 

382 
with operation "modulo", analogously to type class "divide". This 

383 
eliminates the need to qualify any of those names in the presence of 

384 
infix "mod" syntax. INCOMPATIBILITY. 

385 

63979  386 
* Statements and proofs of KnasterTarski fixpoint combinators lfp/gfp 
387 
have been clarified. The fixpoint properties are lfp_fixpoint, its 

388 
symmetric lfp_unfold (as before), and the duals for gfp. Auxiliary items 

389 
for the proof (lfp_lemma2 etc.) are no longer exported, but can be 

390 
easily recovered by composition with eq_refl. Minor INCOMPATIBILITY. 

391 

63977  392 
* Constant "surj" is a mere input abbreviation, to avoid hiding an 
393 
equation in term output. Minor INCOMPATIBILITY. 

394 

395 
* Command 'code_reflect' accepts empty constructor lists for datatypes, 

396 
which renders those abstract effectively. 

397 

398 
* Command 'export_code' checks given constants for abstraction 

399 
violations: a small guarantee that given constants specify a safe 

400 
interface for the generated code. 

401 

402 
* Code generation for Scala: ambiguous implicts in class diagrams are 

403 
spelt out explicitly. 

404 

405 
* Static evaluators (Code_Evaluation.static_* in Isabelle/ML) rely on 

406 
explicitly provided auxiliary definitions for required type class 

407 
dictionaries rather than halfworking magic. INCOMPATIBILITY, see 

408

411

415 

416 
* Locale bijection establishes convenient default simp rules such as 

417 
"inv f (f a) = a" for total bijections. 

418 

419 
* Abstract locales semigroup, abel_semigroup, semilattice, 

420

425 
syntax uniformly that does not clash with corresponding global syntax. 

426 
INCOMPATIBILITY. 

427 

428 
* Former locale lifting_syntax is now a bundle, which is easier to 

429 
include in a local context or theorem statement, e.g. "context includes 

430 
lifting_syntax begin ... end". Minor INCOMPATIBILITY.

797 
for monotonicity and continuity in chaincomplete partial orders and 

798 
about admissibility conditions for fixpoint inductions. 

799 

800 
* HOLLibrary: theory Polynomial contains also derivation of polynomials 

801 
but not gcd/lcm on polynomials over fields. This has been moved to a 

802 
separate theory Library/Polynomial_GCD_euclidean.thy, to pave way for a 

803 
possible future different type class instantiation for polynomials over 

804 
factorial rings. INCOMPATIBILITY.

1122

61215  1136 

61803  1137 
* The text overview column (status of errors, warnings etc.) is updated 
1138 
asynchronously, leading to much better editor reactivity. Moreover, the 

1139 
full document node content is taken into account. The width of the 

1140 
column is scaled according to the main text area font, for improved 

1141 
visibility. 

1142 

1143 
* The main text area no longer changes its color hue in outdated 

1144 
situations. The text overview column takes over the role to indicate 

1145 
unfinished edits in the PIDE pipeline. This avoids flashing text display 

1146 
due to adhoc updates by auxiliary GUI components, such as the State 

1147

* Assumptions ('assume', 'presume') allow structured rule statements 
1283 
using 'if' and 'for', similar to 'have' etc. above. For example: 

61658  1284 

1285 
assume result: "C x y" 

1286 
if "A x" and "B y" 

1287 
for x :: 'a and y :: 'a 

1288 

1289 
This assumes "\<And>x y::'a. A x \<Longrightarrow> B y \<Longrightarrow> C x y" and produces a general 

1290 
result as usual: "A ?x \<Longrightarrow> B ?y \<Longrightarrow> C ?x ?y". 

1291 

1292 
Vacuous quantification in assumptions is omitted, i.e. a forcontext 

1293 
only effects propositions according to actual use of variables. For 

1294 
example: 

1295 

1296 
assume "A x" and "B y" for x and y 

1297 

1298 
is equivalent to: 

1299 

1300 
assume "\<And>x. A x" and "\<And>y. B y" 

1301 

60595  1302 
* The meaning of 'show' with Pure rule statements has changed: premises 
1303 
are treated in the sense of 'assume', instead of 'presume'. This means, 

62205  1304 
a goal like "\<And>x. A x \<Longrightarrow> B x \<Longrightarrow> C x" can be solved completely as 
1305 
follows: 

60595  1306

* New command 'consider' states rules for generalized elimination and 
1318 
case splitting. This is like a toplevel statement "theorem obtains" used 

1319 
within a proof body; or like a multibranch 'obtain' without activation 

1320 
of the local context elements yet. 

1321 

60455  1322 
* Proof method "cases" allows to specify the rule as first entry of 
1323 
chained facts. This is particularly useful with 'consider': 

1324 

1325 
consider (a) A  (b) B  (c) C <proof> 

1326 
then have something 

1327 
proof cases 

1328 
case a 

1329 
then show ?thesis <proof> 

1330 
next 

1331 
case b 

1332 
then show ?thesis <proof> 

1333

1334 
case c

then show ?thesis <proof>

* Command 'case' allows fact name and attribute specification like this: 
1339 

1340 
case a: (c xs) 

1341 
case a [attributes]: (c xs) 

1342 

1343 
Facts that are introduced by invoking the case context are uniformly 

1344 
qualified by "a"; the same name is used for the cumulative fact. The old 

1345 
form "case (c xs) [attributes]" is no longer supported. Rare 

1346 
INCOMPATIBILITY, need to adapt uses of case facts in exotic situations, 

1347 
and always put attributes in front.

* Nesting of Isar goal structure has been clarified: the context after 
1355 
the initial backwards refinement is retained for the whole proof, within 

1356 
all its context sections (as indicated via 'next'). This is e.g. 

1357 
relevant for 'using', 'including', 'supply': 

1358 

1359 
have "A \<and> A" if a: A for A

1368 
proof body as well, abstracted over relevant parameters.

* Improved typeinference for theorem statement 'obtains': separate 

1371 
parameter scope for of each clause. 

1372

* Term abbreviations via 'is' patterns also work for schematic 

1374 
statements: result is abstracted over unknowns.

* Command 'subgoal' allows to impose some structure on backward 
1377 
refinements, to avoid proof scripts degenerating into long of 'apply' 

1378 
sequences. Further explanations and examples are given in the isarref 

1379 
manual.
