60986  15 
* 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.

* Local goals ('have', 'show', 'hence', 'thus') allow structured 
37

example: 
60414  40 

41 
have result: "C x y" 

42 
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" 
60414  53 
have "C x y" <proof> 
54 
}

note result = this

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.

113 

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. 

118 

60578  119 
* Proof method "goals" turns the current subgoals into cases within the 
120 
context; the conclusion is bound to variable ?case in each case. 

60617  121 
For example: 
122 

123 
lemma "\<And>x. A x \<Longrightarrow> B x \<Longrightarrow> C x" 

60622  124 
and "\<And>y z. U y \<Longrightarrow> V z \<Longrightarrow> W y z" 
125 
proof goals 

126 
case (1 x) 

127 
then show ?case using \<open>A x\<close> \<open>B x\<close> sorry 

128 
next 

129 
case (2 y z) 

130 
then show ?case using \<open>U y\<close> \<open>V z\<close> sorry 

131 
qed 

132 

133 
lemma "\<And>x. A x \<Longrightarrow> B x \<Longrightarrow> C x" 

134 
and "\<And>y z. U y \<Longrightarrow> V z \<Longrightarrow> W y z" 

60617  135 
proof goals 
136 
case prems: 1 

137 
then show ?case using prems sorry 

138 
next 

139 
case prems: 2 

140 
then show ?case using prems sorry 

141 
qed 

60578  142 

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 

155 
proof 

156 
show A by simp 

157 
next 

158 
show A by simp 

159 
qed 

160 

60554  161 
* Method "sleep" succeeds after a realtime delay (in seconds). This is 
162 
occasionally useful for demonstration and testing purposes. 

163 

60406  164 

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 

60347  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 *** 
457 

458 
* Document markup commands 'chapter', 'section', 'subsection', 

459 
'subsubsection', 'text', 'txt', 'text_raw' work uniformly in any 

460 
context, even before the initial 'theory' command. Obsolete proof 

461 
commands 'sect', 'subsect', 'subsubsect', 'txt_raw' have been 

462 
discontinued, use 'section', 'subsection', 'subsubsection', 'text_raw' 

463 
instead. The old 'header' command is still retained for some time, but 

464 
should be replaced by 'chapter', 'section' etc. (using "isabelle 

465 
update_header"). Minor INCOMPATIBILITY. 

466 

60009  467 
* Official support for "tt" style variants, via \isatt{...} or 
468 
\begin{isabellett}...\end{isabellett}. The somewhat fragile \verb or 

469 
verbatim environment of LaTeX is no longer used. This allows @{ML} etc. 

470 
as argument to other macros (such as footnotes). 

471 

472 
* Document antiquotation @{verbatim} prints ASCII text literally in "tt" 

473 
style. 

474 

475 
* Discontinued obsolete option "document_graph": session_graph.pdf is 

476 
produced unconditionally for HTML browser_info and PDFLaTeX document. 

477 

59951  478 
* Diagnostic commands and document markup commands within a proof do not 
479 
affect the command tag for output. Thus commands like 'thm' are subject 

480 
to proof document structure, and no longer "stick out" accidentally. 

481 
Commands 'text' and 'txt' merely differ in the LaTeX style, not their 

482 
tags. Potential INCOMPATIBILITY in exotic situations. 

483 

484 
* System option "pretty_margin" is superseded by "thy_output_margin", 

485 
which is also accessible via document antiquotation option "margin". 

486 
Only the margin for document output may be changed, but not the global 

487 
pretty printing: that is 76 for plain console output, and adapted 

488 
dynamically in GUI frontends. Implementations of document 

489 
antiquotations need to observe the margin explicitly according to 

490 
Thy_Output.string_of_margin. Minor INCOMPATIBILITY.

* The functions "sin" and "cos" are now defined for any type of sort 
664 
"{real_normed_algebra_1,banach}" type, so in particular on "real" and 

665 
"complex" uniformly. Minor INCOMPATIBILITY: type constraints may be 

666 
needed. 

667 

668 
* New library of properties of the complex transcendental functions sin, 

669 
cos, tan, exp, Ln, Arctan, Arcsin, Arccos. Ported from HOL Light. 

670 

671 
* The factorial function, "fact", now has type "nat => 'a" (of a sort 

672 
that admits numeric types including nat, int, real and complex. 

673 
INCOMPATIBILITY: an expression such as "fact 3 = 6" may require a type 

674 
constraint, and the combination "real (fact k)" is likely to be 

675 
unsatisfactory. If a type conversion is still necessary, then use 

676 
"of_nat (fact k)" or "real_of_nat (fact k)". 

677 

678 
* Removed functions "natfloor" and "natceiling", use "nat o floor" and 

679 
"nat o ceiling" instead. A few of the lemmas have been retained and 

680 
adapted: in their names "natfloor"/"natceiling" has been replaced by 

681 
"nat_floor"/"nat_ceiling". 

682 

683

693 
mult_less_imp_less_left ~> mult_left_less_imp_less 

694

60009  782 
* Subtle change of name space policy: undeclared entries are now 
783 
considered inaccessible, instead of accessible via the fullyqualified 

784 
internal name. This mainly affects Name_Space.intern (and derivatives), 

785 
which may produce an unexpected Long_Name.hidden prefix. Note that 

60010  786 
contemporary applications use the strict Name_Space.check (and 
60009  787 
derivatives) instead, which is not affected by the change. Potential 
788 
INCOMPATIBILITY in rare applications of Name_Space.intern. 

59951  789

797 
INCOMPATIBILITY. 

798 

799 
* Former combinators NAMED_CRITICAL and CRITICAL for central critical 

800 
sections have been discontinued, in favour of the more elementary 

801 
Multithreading.synchronized and its highlevel derivative 

802 
Synchronized.var (which is usually sufficient in applications). Subtle 

803 
INCOMPATIBILITY: synchronized access needs to be atomic and cannot be 

804 
nested. 

805 

60009  806 
* Synchronized.value (ML) is actually synchronized (as in Scala): subtle 
807

* Support for official Standard ML within the Isabelle context. 
867 
Command 'SML_file' reads and evaluates the given Standard ML file. 

868 
Toplevel bindings are stored within the theory context; the initial 

869 
environment is restricted to the Standard ML implementation of 

870 
Poly/ML, without the addons of Isabelle/ML. Commands 'SML_import' 

871 
and 'SML_export' allow to exchange toplevel bindings between the two 

872

874 

57504  875 
* Standard tactics and proof methods such as "clarsimp", "auto" and 
876 
"safe" now preserve equality hypotheses "x = expr" where x is a free 

877 
variable. Locale assumptions and chained facts containing "x" 

878 
continue to be useful. The new method "hypsubst_thin" and the 

879 
configuration option "hypsubst_thin" (within the attribute name space) 

880 
restore the previous behavior. INCOMPATIBILITY, especially where 

881 
induction is done after these methods or when the names of free and 

882 
bound variables clash. As first approximation, old proofs may be 

883 
repaired by "using [[hypsubst_thin = true]]" in the critical spot. 

884 

56232  885 
* More static checking of proof methods, which allows the system to 
886 
form a closure over the concrete syntax. Method arguments should be 

887 
processed in the original proof context as far as possible, before 

888 
operating on the goal state. In any case, the standard discipline for 

889 
subgoaladdressing needs to be observed: no subgoals or a subgoal 

890 
number that is out of range produces an empty result sequence, not an 

891 
exception. Potential INCOMPATIBILITY for nonconformant tactical 

892 
proof tools. 

893 

57452  894 
* Lexical syntax (inner and outer) supports text cartouches with 
895 
arbitrary nesting, and without escapes of quotes etc. The Prover IDE 

896 
supports input via ` (backquote). 

897 

898 
* The outer syntax categories "text" (for formal comments and document 

899 
markup commands) and "altstring" (for literal fact references) allow 

900 
cartouches as well, in addition to the traditional mix of quotations. 

901 

902 
* Syntax of document antiquotation @{rail} now uses \<newline> instead 

903 
of "\\", to avoid the optical illusion of escaped backslash within 

57491  904 
string token. General renovation of its syntax using text cartouches. 
57452  905 
Minor INCOMPATIBILITY. 
906 

907 
* Discontinued legacy_isub_isup, which was a temporary workaround for 

908 
Isabelle/ML in Isabelle20131. The prover process no longer accepts 

909 
old identifier syntax with \<^isub> or \<^isup>. Potential 

910 
INCOMPATIBILITY. 

911 

912 
* Document antiquotation @{url} produces markup for the given URL, 

913 
which results in an active hyperlink within the text. 

914

916

* Lowlevel typeclass commands 'classes', 'classrel', 'arities' have 
991 
been discontinued to avoid the danger of nontrivial axiomatization 

992 
that is not immediately visible. INCOMPATIBILITY, use regular 

993 
'instance' command with proof. The required OFCLASS(...) theorem 

994 
might be postulated via 'axiomatization' beforehand, or the proof 

995 
finished trivially if the underlying class definition is made vacuous 

996 
(without any assumptions). See also Isabelle/ML operations 

997 
Axclass.class_axiomatization, Axclass.classrel_axiomatization, 

998 
Axclass.arity_axiomatization. 

999 

56245  1000 
* Basic constants of Pure use more conventional names and are always 
1001 
qualified. Rare INCOMPATIBILITY, but with potentially serious 

1002 
consequences, notably for tools in Isabelle/ML. The following 

1003 
renaming needs to be applied: 

1004 

1005 
== ~> Pure.eq 

1006 
==> ~> Pure.imp 

1007 
all ~> Pure.all 

1008 
TYPE ~> Pure.type 

1009 
dummy_pattern ~> Pure.dummy_pattern 

1010 

1011 
Systematic porting works by using the following theory setup on a 

1012 
*previous* Isabelle version to introduce the new name accesses for the 

1013 
old constants: 

1014 

1015 
setup {* 

1016 
fn thy => thy 

1017 
> Sign.root_path 

1018 
> Sign.const_alias (Binding.qualify true "Pure" @{binding eq}) "==" 

1019 
> Sign.const_alias (Binding.qualify true "Pure" @{binding imp}) "==>" 

1020 
> Sign.const_alias (Binding.qualify true "Pure" @{binding all}) "all" 

1021 
> Sign.restore_naming thy 

1022 
*} 

1023 

1024 
Thus ML antiquotations like @{const_name Pure.eq} may be used already. 

1025 
Later the application is moved to the current Isabelle version, and 

1026 
the auxiliary aliases are deleted.

* Obsolete attribute "standard" has been discontinued (legacy since 
1033 
Isabelle2012). Potential INCOMPATIBILITY, use explicit 'for' context 

1034 
where instantiations with schematic variables are intended (for 

1035 
declaration commands like 'lemmas' or attributes like "of"). The 

1036 
following temporary definition may help to port old applications: 

1037 

1038 
attribute_setup standard = 

1039 
"Scan.succeed (Thm.rule_attribute (K Drule.export_without_context))" 

1040

* More thorough check of proof context for goal statements and 
55006  1042

* New internal SAT solver "cdclite" that produces models and proof 
1250 
traces. This solver replaces the internal SAT solvers "enumerate" and 

1251 
"dpll". Applications that explicitly used one of these two SAT 

1252 
solvers should use "cdclite" instead. In addition, "cdclite" is now 

1253 
the default SAT solver for the "sat" and "satx" proof methods and 

1254 
corresponding tactics; the old default can be restored using "declare 

1255 
[[sat_solver = zchaff_with_proofs]]". Minor INCOMPATIBILITY. 

1256 

1257 
* SMT module: A new version of the SMT module, temporarily called 

1258 
"SMT2", uses SMTLIB 2 and supports recent versions of Z3 (e.g., 

1259 
4.3). The new proof method is called "smt2". CVC3 and CVC4 are also 

1260 
supported as oracles. Yices is no longer supported, because no version 

1261 
of the solver can handle both SMTLIB 2 and quantifiers. 

1262 

1263 
* Activation of Z3 now works via "z3_non_commercial" system option 

1264 
(without requiring restart), instead of former settings variable 

1265 
"Z3_NON_COMMERCIAL". The option can be edited in Isabelle/jEdit menu 

1266 
Plugin Options / Isabelle / General. 

1267 

1268 
* Sledgehammer: 

1269 
 Z3 can now produce Isar proofs. 

1270 
 MaSh overhaul: 

57532  1271 
. New SMLbased learning algorithms eliminate the dependency on 
57508  1272 
Python and increase performance and reliability. 
1273 
. MaSh and MeSh are now used by default together with the 

1274 
traditional MePo (MengPaulson) relevance filter. To disable 

1275 
MaSh, set the "MaSh" system option in Isabelle/jEdit Plugin 

1276 
Options / Isabelle / General to "none". 

1277 
 New option: 

1278 
smt_proofs 

1279 
 Renamed options: 

1280 
isar_compress ~> compress 

1281 
isar_try0 ~> try0 

1282 

1283 
INCOMPATIBILITY. 

1284 

1285 
* Removed solvers remote_cvc3 and remote_z3. Use cvc3 and z3 instead. 

1286 

1287 
* Nitpick: 

1288 
 Fixed soundness bug whereby mutually recursive datatypes could 

1289 
take infinite values. 

1290 
 Fixed soundness bug with lowlevel number functions such as 

1291 
"Abs_Integ" and "Rep_Integ". 

1292 
 Removed "std" option. 

1293 
 Renamed "show_datatypes" to "show_types" and "hide_datatypes" to 

1294 
"hide_types". 

1295 

1296 
* Metis: Removed legacy proof method 'metisFT'. Use 'metis 

1297 
(full_types)' instead. INCOMPATIBILITY. 

1298 

1299 
* Try0: Added 'algebra' and 'meson' to the set of proof methods. 

1300 

1301 
* Adjustion of INF and SUP operations: 

1302 
 Elongated constants INFI and SUPR to INFIMUM and SUPREMUM. 

1303 
 Consolidated theorem names containing INFI and SUPR: have INF and 

1304 
SUP instead uniformly. 

1305 
 More aggressive normalization of expressions involving INF and Inf 

1306 
or SUP and Sup. 

1307 
 INF_image and SUP_image do not unfold composition. 

1308 
 Dropped facts INF_comp, SUP_comp. 

1309 
 Default congruence rules strong_INF_cong and strong_SUP_cong, with 

1310 
simplifier implication in premises. Generalize and replace former 

1311 
INT_cong, SUP_cong 

1312 

1313 
INCOMPATIBILITY. 

1314 

1315 
* SUP and INF generalized to conditionally_complete_lattice. 

1316 

1317 
* Swapped orientation of facts image_comp and vimage_comp: 

1318 

1319 
image_compose ~> image_comp [symmetric] 

1320 
image_comp ~> image_comp [symmetric] 

1321 
vimage_compose ~> vimage_comp [symmetric] 

1322 
vimage_comp ~> vimage_comp [symmetric] 

1323 

1324 
INCOMPATIBILITY. 

1325 

57504  1326 
* Theory reorganization: split of Big_Operators.thy into 
1327 
Groups_Big.thy and Lattices_Big.thy. 

55098  1328 

57418  1329
