*** 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is superseded by "(\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

more informative 'prf' and 'full_prf', based on HOL/Proofs/ex/XML_Data.thy;

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.

* 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

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.

293 
which exposed details of the internal fixpoint construction and was 

294 
hard to use. INCOMPATIBILITY. 

295 

296 
* New abbreviations for negated existence (but not bounded existence): 

297 

298 
\<nexists>x. P x \<equiv> \<not> (\<exists>x. P x) 

299 
\<nexists>!x. P x \<equiv> \<not> (\<exists>!x. P x) 

300 

301 
* The print mode "HOL" for ASCII syntax of binders "!", "?", "?!", "@" 

302 
has been removed for output. It is retained for input only, until it is 

303 
eliminated altogether. 

304 

305 
* The unique existence quantifier no longer provides 'binder' syntax, 

306 
but uses syntax translations (as for bounded unique existence). Thus 

307 
iterated quantification \<exists>!x y. P x y with its slightly confusing 

308 
sequential meaning \<exists>!x. \<exists>!y. P x y is no longer possible. Instead, 

309 
pattern abstraction admits simultaneous unique existence \<exists>!(x, y). P x y 

310 
(analogous to existing notation \<exists>!(x, y)\<in>A. P x y). Potential 

311 
INCOMPATIBILITY in rare situations. 

312 

313 
* Conventional syntax "%(). t" for unit abstractions. Slight syntactic 

314 
INCOMPATIBILITY. 

315 

316 
* Characters (type char) are modelled as finite algebraic type 

317 
corresponding to {0..255}. 

318 

319 
 Logical representation: 

320 
* 0 is instantiated to the ASCII zero character. 

321 
* All other characters are represented as "Char n" 

322 
with n being a raw numeral expression less than 256. 

323 
* Expressions of the form "Char n" with n greater than 255 

324 
are noncanonical. 

325 
 Printing and parsing: 

326 
* Printable characters are printed and parsed as "CHR ''\<dots>''" 

327 
(as before). 

328 
* The ASCII zero character is printed and parsed as "0". 

329 
* All other canonical characters are printed as "CHR 0xXX" 

330 
with XX being the hexadecimal character code. "CHR n" 

331 
is parsable for every numeral expression n. 

332 
* Noncanonical characters have no special syntax and are 

333 
printed as their logical representation. 

334 
 Explicit conversions from and to the natural numbers are 

335 
provided as char_of_nat, nat_of_char (as before). 

336 
 The auxiliary nibble type has been discontinued. 

337 

338 
INCOMPATIBILITY. 

339 

340 
* Type class "div" with operation "mod" renamed to type class "modulo" 

341 
with operation "modulo", analogously to type class "divide". This 

342 
eliminates the need to qualify any of those names in the presence of 

343 
infix "mod" syntax. INCOMPATIBILITY. 

344 

63979  345 
* Statements and proofs of KnasterTarski fixpoint combinators lfp/gfp 
346 
have been clarified. The fixpoint properties are lfp_fixpoint, its 

347 
symmetric lfp_unfold (as before), and the duals for gfp. Auxiliary items 

348 
for the proof (lfp_lemma2 etc.) are no longer exported, but can be 

349 
easily recovered by composition with eq_refl. Minor INCOMPATIBILITY. 

350 

63977  351 
* Constant "surj" is a mere input abbreviation, to avoid hiding an 
352 
equation in term output. Minor INCOMPATIBILITY. 

353 

354 
* Command 'code_reflect' accepts empty constructor lists for datatypes, 

355 
which renders those abstract effectively. 

356 

357 
* Command 'export_code' checks given constants for abstraction 

358 
violations: a small guarantee that given constants specify a safe 

359 
interface for the generated code. 

360 

361 
* Code generation for Scala: ambiguous implicts in class diagrams are 

362 
spelt out explicitly. 

363 

364 
* Static evaluators (Code_Evaluation.static_* in Isabelle/ML) rely on 

365 
explicitly provided auxiliary definitions for required type class 

366 
dictionaries rather than halfworking magic. INCOMPATIBILITY, see 

367 
the tutorial on code generation for details. 

368 

369 
* Theory Set_Interval.thy: substantial new theorems on indexed sums 

370 
and products. 

371 

372 
* Theory List.thy: ranaming of listsum ~> sum_list, listprod ~> 

373 
prod_list, INCOMPATIBILITY. 

374 

375 
* Locale bijection establishes convenient default simp rules such as 

376 
"inv f (f a) = a" for total bijections. 

377 

378 
* Abstract locales semigroup, abel_semigroup, semilattice, 

379 
semilattice_neutr, ordering, ordering_top, semilattice_order, 

380 
semilattice_neutr_order, comm_monoid_set, semilattice_set, 

381 
semilattice_neutr_set, semilattice_order_set, 

382 
semilattice_order_neutr_set monoid_list, comm_monoid_list, 

383 
comm_monoid_list_set, comm_monoid_mset, comm_monoid_fun use boldified 

384 
syntax uniformly that does not clash with corresponding global syntax. 

385 
INCOMPATIBILITY. 

386 

387 
* Former locale lifting_syntax is now a bundle, which is easier to 

388 
include in a local context or theorem statement, e.g. "context includes 

389 
lifting_syntax begin ... end". Minor INCOMPATIBILITY. 

390 

63807  391 
* Some old / obsolete theorems have been renamed / removed, potential 
392 
INCOMPATIBILITY. 

393 

394 
nat_less_cases  removed, use linorder_cases instead 

395 
inv_image_comp  removed, use image_inv_f_f instead 

396 
image_surj_f_inv_f ~> image_f_inv_f

instantiating linordered_semiring_strict and ordered_ab_group_add, an 
753

754 
be required. INCOMPATIBILITY.

756 
* HOLLibrary: theory Complete_Partial_Order2 provides reasoning support 

757 
for monotonicity and continuity in chaincomplete partial orders and 

758 
about admissibility conditions for fixpoint inductions. 

759 

760 
* HOLLibrary: theory Polynomial contains also derivation of polynomials 

761 
but not gcd/lcm on polynomials over fields. This has been moved to a 

762 
separate theory Library/Polynomial_GCD_euclidean.thy, to pave way for a 

763 
possible future different type class instantiation for polynomials over 

764 
factorial rings. INCOMPATIBILITY. 

765 

766 
* HOLLibrary: theory Sublist.thy provides function "prefixes" with the 

767 
following renaming

63173  769 
prefixeq > prefix 
770 
prefix > strict_prefix 

771 
suffixeq > suffix

* IDE support for the sourcelevel debugger of Poly/ML, to work with 
62253  1055 
Isabelle/ML and official Standard ML. Option "ML_debugger" and commands 
1056 
'ML_file_debug', 'ML_file_no_debug', 'SML_file_debug', 

1057 
'SML_file_no_debug' control compilation of sources with or without 

1058 
debugging information. The Debugger panel allows to set breakpoints (via 

1059 
context menu), step through stopped threads, evaluate local ML 

1060 
expressions etc. At least one Debugger view needs to be active to have 

1061 
any effect on the running ML program. 

60984  1062

* The State panel manages explicit proof state output, with dynamic 
1064 
autoupdate according to cursor movement. Alternatively, the jEdit 

1065 
action "isabelle.updatestate" (shortcut S+ENTER) triggers manual 

1066 
update. 

61729  1067 

1068 
* The Output panel no longer shows proof state output by default, to 

1069 
avoid GUI overcrowding. INCOMPATIBILITY, use the State panel instead or 

1070 
enable option "editor_output_state". 

61215  1071 

61803  1072 
* The text overview column (status of errors, warnings etc.) is updated 
1073 
asynchronously, leading to much better editor reactivity. Moreover, the 

1074 
full document node content is taken into account. The width of the 

1075 
column is scaled according to the main text area font, for improved 

1076 
visibility. 

1077 

1078 
* The main text area no longer changes its color hue in outdated 

1079 
situations. The text overview column takes over the role to indicate 

1080 
unfinished edits in the PIDE pipeline. This avoids flashing text display 

1081 
due to adhoc updates by auxiliary GUI components, such as the State 

1082 
panel.

* Commands 'paragraph' and 'subparagraph' provide additional section 
1130 
headings. Thus there are 6 levels of standard headings, as in HTML. 

1131 

1132 
* Command 'text_raw' has been clarified: input text is processed as in 

1133 
'text' (with antiquotations and control symbols). The key difference is 

1134 
the lack of the surrounding isabelle markup environment in output. 

1135 

1136 
* Text is structured in paragraphs and nested lists, using notation that 

1137 
is similar to Markdown. The control symbols for list items are as 

1138 
follows: 

1139 

1140

that is a cartouche: \<^name>\<open>...\<close> is equivalent to @{name \<open>...\<close>} and 
61595  1146

1147 
\<^name> without following cartouche is equivalent to @{name}. The 

61501  1148 
standard Isabelle fonts provide glyphs to render important control 
1149

60449  1203 
The local assumptions are bound to the name "that". The result is 
1204 
exported from context of the statement as usual. The above roughly 

60414  1205 
corresponds to a raw proof block like this:

61733  1217 
* Assumptions ('assume', 'presume') allow structured rule statements 
1218 
using 'if' and 'for', similar to 'have' etc. above. For example: 

61658  1219 

1220 
assume result: "C x y" 

1221 
if "A x" and "B y" 

1222 
for x :: 'a and y :: 'a 

1223 

1224 
This assumes "\<And>x y::'a. A x \<Longrightarrow> B y \<Longrightarrow> C x y" and produces a general 

1225 
result as usual: "A ?x \<Longrightarrow> B ?y \<Longrightarrow> C ?x ?y". 

1226 

1227 
Vacuous quantification in assumptions is omitted, i.e. a forcontext 

1228 
only effects propositions according to actual use of variables. For 

1229 
example: 

1230 

1231 
assume "A x" and "B y" for x and y 

1232 

1233 
is equivalent to: 

1234 

1235 
assume "\<And>x. A x" and "\<And>y. B y" 

1236 

60595  1237 
* The meaning of 'show' with Pure rule statements has changed: premises 
1238 
are treated in the sense of 'assume', instead of 'presume'. This means, 

62205  1239 
a goal like "\<And>x. A x \<Longrightarrow> B x \<Longrightarrow> C x" can be solved completely as 
1240 
follows: 

60595  1241 

1242 
show "\<And>x. A x \<Longrightarrow> B x \<Longrightarrow> C x" 

1243 

1244 
or: 

1245 

1246 
show "C x" if "A x" "B x" for x 

1247 

1248 
Rare INCOMPATIBILITY, the old behaviour may be recovered as follows: 

1249 

1250 
show "C x" when "A x" "B x" for x 

1251 

60459  1252 
* New command 'consider' states rules for generalized elimination and 
1253 
case splitting. This is like a toplevel statement "theorem obtains" used 

1254 
within a proof body; or like a multibranch 'obtain' without activation 

1255 
of the local context elements yet. 

1256 

60455  1257 
* Proof method "cases" allows to specify the rule as first entry of 
1258 
chained facts. This is particularly useful with 'consider': 

1259 

1260 
consider (a) A  (b) B  (c) C <proof> 

1261 
then have something 

1262 
proof cases 

1263 
case a 

1264 
then show ?thesis <proof> 

1265 
next 

1266 
case b 

1267 
then show ?thesis <proof> 

1268 
next 

1269 
case c 

1270 
then show ?thesis <proof> 

1271 
qed 

1272 

60565  1273 
* Command 'case' allows fact name and attribute specification like this: 
1274 

1275 
case a: (c xs) 

1276 
case a [attributes]: (c xs) 

1277 

1278 
Facts that are introduced by invoking the case context are uniformly 

1279 
qualified by "a"; the same name is used for the cumulative fact. The old 

1280 
form "case (c xs) [attributes]" is no longer supported. Rare 

1281 
INCOMPATIBILITY, need to adapt uses of case facts in exotic situations, 

1282

* Nesting of Isar goal structure has been clarified: the context after 
1290 
the initial backwards refinement is retained for the whole proof, within 

1291

1292 
relevant for 'using', 'including', 'supply':

* The undocumented feature of implicit cases goal1, goal2, goal3, etc. 
60617  1344 
is marked as legacy, and will be removed eventually. The proof method 
1345 
"goals" achieves a similar effect within regular Isar; often it can be 

1346 
done more adequately by other means (e.g. 'consider').

* More gentle suppression of syntax along locale morphisms while

'abbreviation' is also kept for morphims that only change the involved 
62017  1369 
parameters, and only 'notation' is suppressed. This can be of great help 
1370 
when working with complex locale hierarchies, because proof states are 

1371 
displayed much more succinctly. It also means that only notation needs 

1372 
to be redeclared if desired, as illustrated by this example:
