* IDE support for the sourcelevel debugger of Poly/ML, to work with 
60984  16 
Isabelle/ML and official Standard ML. Configuration option "ML_debugger" 
17 
and commands 'ML_file_debug', 'ML_file_no_debug', 'SML_file_debug', 

18 
'SML_file_no_debug' control compilation of sources with debugging 

19 
information. The Debugger panel allows to set breakpoints (via context 

20 
menu), step through stopped threads, evaluate local ML expressions etc. 

21 
At least one Debugger view needs to be active to have any effect on the 

22 
running ML program.

have result: "C x y"

if "A x" and "B y" 

43 
for x :: 'a and y :: 'a 

44 
<proof> 

45 

60449  46 
The local assumptions are bound to the name "that". The result is 
47 
exported from context of the statement as usual. The above roughly 

60414  48 
corresponds to a raw proof block like this: 
49 

50 
{ 

51 
fix x :: 'a and y :: 'a 

60449  52 
assume that: "A x" "B y"

have "C x y" <proof>

59 

60595  60 
* The meaning of 'show' with Pure rule statements has changed: premises 
61 
are treated in the sense of 'assume', instead of 'presume'. This means, 

62 
a goal like "\<And>x. A x \<Longrightarrow> B x \<Longrightarrow> C x" can be solved completely as follows: 

63 

64 
show "\<And>x. A x \<Longrightarrow> B x \<Longrightarrow> C x" 

65 

66 
or: 

67 

68 
show "C x" if "A x" "B x" for x 

69 

70 
Rare INCOMPATIBILITY, the old behaviour may be recovered as follows: 

71 

72 
show "C x" when "A x" "B x" for x 

73 

60406  74 
* New command 'supply' supports fact definitions during goal refinement 
75 
('apply' scripts). 

76 

60459  77 
* New command 'consider' states rules for generalized elimination and 
78 
case splitting. This is like a toplevel statement "theorem obtains" used 

79 
within a proof body; or like a multibranch 'obtain' without activation 

80 
of the local context elements yet. 

81 

60455  82 
* Proof method "cases" allows to specify the rule as first entry of 
83 
chained facts. This is particularly useful with 'consider': 

84 

85 
consider (a) A  (b) B  (c) C <proof> 

86 
then have something 

87 
proof cases 

88 
case a 

89 
then show ?thesis <proof> 

90 
next 

91 
case b 

92 
then show ?thesis <proof> 

93 
next 

94 
case c 

95 
then show ?thesis <proof> 

96 
qed 

97 

60565  98 
* Command 'case' allows fact name and attribute specification like this: 
99 

100 
case a: (c xs) 

101 
case a [attributes]: (c xs) 

102 

103 
Facts that are introduced by invoking the case context are uniformly 

104 
qualified by "a"; the same name is used for the cumulative fact. The old 

105 
form "case (c xs) [attributes]" is no longer supported. Rare 

106 
INCOMPATIBILITY, need to adapt uses of case facts in exotic situations, 

107 
and always put attributes in front.

60631  114 
* Command 'subgoal' allows to impose some structure on backward 
115 
refinements, to avoid proof scripts degenerating into long of 'apply' 

116 
sequences. Further explanations and examples are given in the isarref 

117 
manual.

60581  143 
* The undocumented feature of implicit cases goal1, goal2, goal3, etc. 
60617  144 
is marked as legacy, and will be removed eventually. The proof method 
145 
"goals" achieves a similar effect within regular Isar; often it can be 

146 
done more adequately by other means (e.g. 'consider'). 

60581  147 

60551  148 
* Nesting of Isar goal structure has been clarified: the context after 
149 
the initial backwards refinement is retained for the whole proof, within 

150 
all its context sections (as indicated via 'next'). This is e.g. 

151 
relevant for 'using', 'including', 'supply': 

152 

153 
have "A \<and> A" if a: A for A 

154 
supply [simp] = a

* Method "sleep" succeeds after a realtime delay (in seconds). This is 
162 
occasionally useful for demonstration and testing purposes.

60331  165 
*** Pure *** 
166 

60489  167 
* The vacuous fact "TERM x" may be established "by fact" or as `TERM x` 
168 
as well, not just "by this" or "." as before. 

169 

60331  170 
* Configuration option rule_insts_schematic has been discontinued 
171 
(intermediate legacy feature in Isabelle2015). INCOMPATIBILITY. 

172 

60349  173 
* Abbreviations in type classes now carry proper sort constraint. 
174 
Rare INCOMPATIBILITY in situations where the previous misbehaviour 

175 
has been exploited previously. 

176 

177 
* Refinement of userspace type system in type classes: pseudolocal 

178 
operations behave more similar to abbreviations. Potential 

179 
INCOMPATIBILITY in exotic situations. 

180 

181 

60171  182 
*** HOL *** 
183 

61118  184 
* Qualification of various formal entities in the libraries is done more 
185 
uniformly via "context begin qualified definition ... end" instead of 

186 
oldstyle "hide_const (open) ...". Consequently, both the defined 

187 
constant and its defining fact become qualified, e.g. Option.is_none and 

188 
Option.is_none_def. Occasional INCOMPATIBILITY in applications.

*** Document preparation *** 
466 

467 
* Document markup commands 'chapter', 'section', 'subsection', 

468 
'subsubsection', 'text', 'txt', 'text_raw' work uniformly in any 

469 
context, even before the initial 'theory' command. Obsolete proof 

470 
commands 'sect', 'subsect', 'subsubsect', 'txt_raw' have been 

471 
discontinued, use 'section', 'subsection', 'subsubsection', 'text_raw' 

472 
instead. The old 'header' command is still retained for some time, but 

473 
should be replaced by 'chapter', 'section' etc. (using "isabelle 

474 
update_header"). Minor INCOMPATIBILITY. 

475 

60010  476 
* Official support for "tt" style variants, via \isatt{...} or 
477 
\begin{isabellett}...\end{isabellett}. The somewhat fragile \verb or 

478 
verbatim environment of LaTeX is no longer used. This allows @{ML} etc. 

479 
as argument to other macros (such as footnotes). 

480 

481 
* Document antiquotation @{verbatim} prints ASCII text literally in "tt" 

482 
style. 

483 

484 
* Discontinued obsolete option "document_graph": session_graph.pdf is 

485 
produced unconditionally for HTML browser_info and PDFLaTeX document. 

486 

59951  487 
* Diagnostic commands and document markup commands within a proof do not 
488 
affect the command tag for output. Thus commands like 'thm' are subject 

489 
to proof document structure, and no longer "stick out" accidentally. 

490 
Commands 'text' and 'txt' merely differ in the LaTeX style, not their 

491 
tags. Potential INCOMPATIBILITY in exotic situations. 

492 

493 
* System option "pretty_margin" is superseded by "thy_output_margin", 

494 
which is also accessible via document antiquotation option "margin". 

495 
Only the margin for document output may be changed, but not the global 

496 
pretty printing: that is 76 for plain console output, and adapted 

497 
dynamically in GUI frontends. Implementations of document 

498 
antiquotations need to observe the margin explicitly according to 

499 
Thy_Output.string_of_margin. Minor INCOMPATIBILITY.

680 
* The factorial function, "fact", now has type "nat => 'a" (of a sort 

681 
that admits numeric types including nat, int, real and complex. 

682 
INCOMPATIBILITY: an expression such as "fact 3 = 6" may require a type

* Subtle change of name space policy: undeclared entries are now 
792 
considered inaccessible, instead of accessible via the fullyqualified

internal name. This mainly affects Name_Space.intern (and derivatives), 

794 
which may produce an unexpected Long_Name.hidden prefix. Note that

Synchronized.var (which is usually sufficient in applications). Subtle

883 

57504  884 
* Standard tactics and proof methods such as "clarsimp", "auto" and 
885 
"safe" now preserve equality hypotheses "x = expr" where x is a free 

886 
variable. Locale assumptions and chained facts containing "x" 

887 
continue to be useful. The new method "hypsubst_thin" and the 

888 
configuration option "hypsubst_thin" (within the attribute name space) 

889 
restore the previous behavior. INCOMPATIBILITY, especially where 

890 
induction is done after these methods or when the names of free and 

891 
bound variables clash. As first approximation, old proofs may be 

892 
repaired by "using [[hypsubst_thin = true]]" in the critical spot. 

893 

56232  894 
* More static checking of proof methods, which allows the system to 
895 
form a closure over the concrete syntax. Method arguments should be 

896 
processed in the original proof context as far as possible, before 

897 
operating on the goal state. In any case, the standard discipline for 

898 
subgoaladdressing needs to be observed: no subgoals or a subgoal 

899 
number that is out of range produces an empty result sequence, not an 

900 
exception. Potential INCOMPATIBILITY for nonconformant tactical 

901 
proof tools. 

902 

57452  903 
* Lexical syntax (inner and outer) supports text cartouches with 
904 
arbitrary nesting, and without escapes of quotes etc. The Prover IDE 

905 
supports input via ` (backquote). 

906 

907 
* The outer syntax categories "text" (for formal comments and document 

908 
markup commands) and "altstring" (for literal fact references) allow 

909 
cartouches as well, in addition to the traditional mix of quotations. 

910 

911 
* Syntax of document antiquotation @{rail} now uses \<newline> instead 

912 
of "\\", to avoid the optical illusion of escaped backslash within 

57491  913 
string token. General renovation of its syntax using text cartouches. 
57452  914 
Minor INCOMPATIBILITY. 
915

918

* Lowlevel typeclass commands 'classes', 'classrel', 'arities' have 
1000 
been discontinued to avoid the danger of nontrivial axiomatization 

1001 
that is not immediately visible. INCOMPATIBILITY, use regular 

1002 
'instance' command with proof. The required OFCLASS(...) theorem 

1003 
might be postulated via 'axiomatization' beforehand, or the proof 

1004 
finished trivially if the underlying class definition is made vacuous 

1005 
(without any assumptions). See also Isabelle/ML operations 

1006 
Axclass.class_axiomatization, Axclass.classrel_axiomatization, 

1007 
Axclass.arity_axiomatization. 

1008 

56245  1009 
* Basic constants of Pure use more conventional names and are always 
1010 
qualified. Rare INCOMPATIBILITY, but with potentially serious 

1011 
consequences, notably for tools in Isabelle/ML. The following 

1012 
renaming needs to be applied: 

1013 

1014 
== ~> Pure.eq 

1015 
==> ~> Pure.imp 

1016 
all ~> Pure.all 

1017 
TYPE ~> Pure.type 

1018 
dummy_pattern ~> Pure.dummy_pattern 

1019 

1020 
Systematic porting works by using the following theory setup on a 

1021 
*previous* Isabelle version to introduce the new name accesses for the 

1022 
old constants: 

1023 

1024 
setup {* 

1025 
fn thy => thy 

1026 
> Sign.root_path 

1027 
> Sign.const_alias (Binding.qualify true "Pure" @{binding eq}) "==" 

1028 
> Sign.const_alias (Binding.qualify true "Pure" @{binding imp}) "==>" 

1029 
> Sign.const_alias (Binding.qualify true "Pure" @{binding all}) "all" 

1030 
> Sign.restore_naming thy 

1031 
*} 

1032 

1033 
Thus ML antiquotations like @{const_name Pure.eq} may be used already. 

1034 
Later the application is moved to the current Isabelle version, and 

1035 
the auxiliary aliases are deleted.

* Obsolete attribute "standard" has been discontinued (legacy since

1043 
where instantiations with schematic variables are intended (for 

1044 
declaration commands like 'lemmas' or attributes like "of"). The 

1045 
following temporary definition may help to port old applications: 

1046

"Scan.succeed (Thm.rule_attribute (K Drule.export_without_context))"

57508  1258 
* New internal SAT solver "cdclite" that produces models and proof 
1259 
traces. This solver replaces the internal SAT solvers "enumerate" and 

1260 
"dpll". Applications that explicitly used one of these two SAT 

1261 
solvers should use "cdclite" instead. In addition, "cdclite" is now 

1262 
the default SAT solver for the "sat" and "satx" proof methods and 

1263 
corresponding tactics; the old default can be restored using "declare 

1264 
[[sat_solver = zchaff_with_proofs]]". Minor INCOMPATIBILITY. 

1265 

1266 
* SMT module: A new version of the SMT module, temporarily called 

1267 
"SMT2", uses SMTLIB 2 and supports recent versions of Z3 (e.g., 

1268 
4.3). The new proof method is called "smt2". CVC3 and CVC4 are also 

1269 
supported as oracles. Yices is no longer supported, because no version 

1270 
of the solver can handle both SMTLIB 2 and quantifiers. 

1271 

1272 
* Activation of Z3 now works via "z3_non_commercial" system option 

1273 
(without requiring restart), instead of former settings variable 

1274 
"Z3_NON_COMMERCIAL". The option can be edited in Isabelle/jEdit menu 

1275 
Plugin Options / Isabelle / General. 

1276 

1277 
* Sledgehammer: 

1278 
 Z3 can now produce Isar proofs. 

1279 
 MaSh overhaul: 

57532  1280 
. New SMLbased learning algorithms eliminate the dependency on 
57508  1281 
Python and increase performance and reliability. 
1282 
. MaSh and MeSh are now used by default together with the 

1283 
traditional MePo (MengPaulson) relevance filter. To disable 

1284 
MaSh, set the "MaSh" system option in Isabelle/jEdit Plugin 

1285 
Options / Isabelle / General to "none". 

1286 
 New option: 

1287 
smt_proofs 

1288 
 Renamed options: 

1289 
isar_compress ~> compress 

1290 
isar_try0 ~> try0 

1291 

1292 
INCOMPATIBILITY. 

1293 

1294 
* Removed solvers remote_cvc3 and remote_z3. Use cvc3 and z3 instead. 

1295 

1296 
* Nitpick: 

1297 
 Fixed soundness bug whereby mutually recursive datatypes could 

1298 
take infinite values. 

1299 
 Fixed soundness bug with lowlevel number functions such as 

1300 
"Abs_Integ" and "Rep_Integ". 

1301 
 Removed "std" option. 

1302 
 Renamed "show_datatypes" to "show_types" and "hide_datatypes" to 

1303 
"hide_types". 

1304 

1305 
* Metis: Removed legacy proof method 'metisFT'. Use 'metis 

1306 
(full_types)' instead. INCOMPATIBILITY. 

1307 

1308 
* Try0: Added 'algebra' and 'meson' to the set of proof methods. 

1309 

1310 
* Adjustion of INF and SUP operations: 

1311 
 Elongated constants INFI and SUPR to INFIMUM and SUPREMUM. 

1312 
 Consolidated theorem names containing INFI and SUPR: have INF and 

1313 
SUP instead uniformly. 

1314 
 More aggressive normalization of expressions involving INF and Inf 

1315 
or SUP and Sup. 

1316 
 INF_image and SUP_image do not unfold composition. 

1317 
 Dropped facts INF_comp, SUP_comp. 

1318 
 Default congruence rules strong_INF_cong and strong_SUP_cong, with 

1319 
simplifier implication in premises. Generalize and replace former 

1320 
INT_cong, SUP_cong 

1321 

1322 
INCOMPATIBILITY. 

1323 

1324 
* SUP and INF generalized to conditionally_complete_lattice. 

1325 

1326 
* Swapped orientation of facts image_comp and vimage_comp: 

1327 

1328 
image_compose ~> image_comp [symmetric] 

1329 
image_comp ~> image_comp [symmetric] 

1330 
vimage_compose ~> vimage_comp [symmetric] 

1331 
vimage_comp ~> vimage_comp [symmetric] 

1332 

1333 
INCOMPATIBILITY. 

1334 

57504  1335 
* Theory reorganization: split of Big_Operators.thy into 
1336 
Groups_Big.thy and Lattices_Big.thy. 

55098  1337 

57418  1338
