* Document antiquotation @{file_unchecked} is like @{file}, but does

54732  15 
* Discontinued legacy_isub_isup, which was a temporary Isabelle/ML 
16

22 

55122  23 
* Lexical syntax (inner and outer) supports text cartouches with 
55668  24 
arbitrary nesting, and without escapes of quotes etc. The Prover IDE 
25 
supports input methods via ` (backquote), or << and >> (double angle 

26 
brackets). 

55122  27 

56232  28 
* More static checking of proof methods, which allows the system to 
29 
form a closure over the concrete syntax. Method arguments should be 

30 
processed in the original proof context as far as possible, before 

31 
operating on the goal state. In any case, the standard discipline for 

32 
subgoaladdressing needs to be observed: no subgoals or a subgoal 

33 
number that is out of range produces an empty result sequence, not an 

34 
exception. Potential INCOMPATIBILITY for nonconformant tactical 

35 
proof tools.

*** Prover IDE  Isabelle/Scala/jEdit *** 
45 

56342  46 
* Improved syntactic and semantic completion mechanism: 
47 

48 
 No completion for Isar keywords that have already been recognized 

49 
by the prover, e.g. ":" within accepted Isar syntax looses its 

50 
meaning as abbreviation for symbol "\<in>". 

51 

52 
 Completion context provides information about embedded languages 

53 
of Isabelle: keywords are only completed for outer syntax, symbols 

54 
or antiquotations for languages that support them. E.g. no symbol 

55 
completion for ML source, but within ML strings, comments, 

56 
antiquotations. 

57 

58 
 Support for semantic completion based on failed name space lookup. 

59 
The error produced by the prover contains information about 

60 
alternative names that are accessible in a particular position. 

61 
This may be used with explicit completion (C+b) or implicit 

62 
completion after some delay. 

63 

64 
 Semantic completions may get extended by appending a suffix of 

65 
underscores to an already recognized name, e.g. "foo_" to complete 

66 
"foo" or "foobar" if these are known in the context. The special 

67 
identifier "__" serves as a wildcard in this respect: it 

68 
completes to the full collection of names from the name space 

69 
(truncated according to the system option "completion_limit"). 

70 

71 
 Syntax completion of the editor and semantic completion of the 

72 
prover are merged. Since the latter requires a full roundtrip of 

73 
document update to arrive, the default for option 

74 
jedit_completion_delay has been changed to 0.5s to improve the 

75 
user experience. 

76 

77 
 Option jedit_completion_immediate may now get used with 

78 
jedit_completion_delay > 0, to complete symbol abbreviations 

79 
aggressively while benefiting from combined syntactic and semantic 

80 
completion. 

81 

82 
 Support for simple completion templates (with single 

83 
placeholder), e.g. "`" for text cartouche, or "@{" for 

84 
antiquotation. 

85 

86 
 Improved treatment of completion vs. various forms of jEdit text 

87 
selection (multiple selections, rectangular selections, 

88 
rectangular selection as "tall caret"). 

89 

90 
 More reliable treatment of GUI events vs. completion popups: avoid 

91 
loosing keystrokes with slow / remote graphics displays. 

92 

54533  93 
* Auxiliary files ('ML_file' etc.) are managed by the Prover IDE. 
94 
Open text buffers take precedence over copies within the filesystem. 

95 

55536  96 
* Improved support for Isabelle/ML, with jEdit mode "isabelleml" for 
97 
auxiliary ML files. 

98 

54688  99 
* Document panel: simplied interaction where every single mouse click 
100 
(re)opens document via desktop environment or as jEdit buffer. 

101 

54881  102 
* Option "jedit_print_mode" (see also "Plugin Options / Isabelle / 
103 
General") allows to specify additional print modes for the prover 

104 
process, without requiring oldfashioned commandline invocation of 

105 
"isabelle jedit m MODE".

55001  112 
*** Pure *** 
113 

56245  114 
* Basic constants of Pure use more conventional names and are always 
115 
qualified. Rare INCOMPATIBILITY, but with potentially serious 

116 
consequences, notably for tools in Isabelle/ML. The following 

117 
renaming needs to be applied: 

118 

119 
== ~> Pure.eq 

120 
==> ~> Pure.imp 

121 
all ~> Pure.all 

122 
TYPE ~> Pure.type 

123 
dummy_pattern ~> Pure.dummy_pattern 

124 

125 
Systematic porting works by using the following theory setup on a 

126 
*previous* Isabelle version to introduce the new name accesses for the 

127 
old constants: 

128 

129 
setup {* 

130 
fn thy => thy 

131 
> Sign.root_path 

132 
> Sign.const_alias (Binding.qualify true "Pure" @{binding eq}) "==" 

133 
> Sign.const_alias (Binding.qualify true "Pure" @{binding imp}) "==>" 

134 
> Sign.const_alias (Binding.qualify true "Pure" @{binding all}) "all" 

135 
> Sign.restore_naming thy 

136 
*} 

137 

138 
Thus ML antiquotations like @{const_name Pure.eq} may be used already. 

139 
Later the application is moved to the current Isabelle version, and 

140 
the auxiliary aliases are deleted.

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

158 
where instantiations with schematic variables are intended (for 

159 
declaration commands like 'lemmas' or attributes like "of"). The 

160 
following temporary definition may help to port old applications: 

161 

162 
attribute_setup standard = 

163 
"Scan.succeed (Thm.rule_attribute (K Drule.export_without_context))" 

164

* More thorough check of proof context for goal statements and 
55006  166 
attributed fact expressions (concerning background theory, declared 
167

168 
context discipline. See also Assumption.add_assumes and the more 

169 
primitive Thm.assume_hyps.

745 
same timing information is shown in the extended tooltip of the

752 
be marked explicitly as required and checked in full, using check box 

753 
or shortcut "C+e SPACE". 

754 

54305  755 
* Improved completion mechanism, which is now managed by the 
756 
Isabelle/jEdit plugin instead of SideKick. Refined table of Isabelle 

757 
symbol abbreviations (see $ISABELLE_HOME/etc/symbols). 

758

INCOMPATIBILITY wrt. jEdit defaults, may have to invent new shortcuts 

762

763 

54305  764 
* Improved support of various "minor modes" for Isabelle NEWS, 
765 
options, session ROOT etc., with completion and SideKick tree view. 

766 

53971  767

* Commands 'interpretation' and 'sublocale' are now targetsensitive. 
796 
In particular, 'interpretation' allows for nonpersistent 

797 
interpretation within "context ... begin ... end" blocks offering a 

798 
lightweight alternative to 'sublocale'. See "isarref" manual for 

799

861 
natural (replaces former code_numeral) and integer (replaces former

869 
f_g.cases which exposed internal sum types. Potential INCOMPATIBILITY, 

870 
in the case that the unusable rule was used nevertheless. 

871 

872 
* Function package: For each function f, new rules f.elims are 

873 
generated, which eliminate equalities of the form "f x = t". 

874 

875 
* New command 'fun_cases' derives adhoc elimination rules for 

876 
function equations as simplified instances of f.elims, analogous to 

877 
inductive_cases. See ~~/src/HOL/ex/Fundefs.thy for some examples. 

53307  878

54378  881 
+ parametricity theorems for the raw term can be specified in 
54021  882 
the command lift_definition, which allow us to generate stronger 
883 
transfer rules 

884 
+ setup_lifting generates stronger transfer rules if parametric 

885 
correspondence relation can be generated 

886 
+ various new properties of the relator must be specified to support 

887 
parametricity 

888

889 
 setup_lifting generates domain rules for the Transfer package 

890 
 stronger reflexivity prover of respectfulness theorems for type 

891

892 
 ===> and > are now local. The symbols can be introduced 

893

894 
anonymous context)

 Reification is now directly available in HOLMain in structure 
912 
"Reification". 

913 
 Reflection now handles multiple lists with variables also. 

914 
 The whole reflection stack has been decomposed into conversions. 

52286  915

916 

51489  917 
* Revised devices for recursive definitions over finite sets: 
918 
 Only one fundamental fold combinator on finite set remains: 

919 
Finite_Set.fold :: ('a => 'b => 'b) => 'b => 'a set => 'b

53362  943 
INCOMPATIBILITY. 
944 

53160  945 
* Introduce type class "conditionally_complete_lattice": Like a 
946 
complete lattice but does not assume the existence of the top and 

947 
bottom elements. Allows to generalize some lemmas about reals and 

948 
extended reals. Removed SupInf and replaced it by the instantiation 

949 
of conditionally_complete_lattice for real. Renamed lemmas about 

950 
conditionallycomplete lattice from Sup_... to cSup_... and from 

951 
Inf_... to cInf_... to avoid hidding of similar complete lattice 

952 
lemmas. 

953 

954 
* Introduce type class linear_continuum as combination of 

955 
conditionallycomplete lattices and inner dense linorders which have 

956 
more than one element. INCOMPATIBILITY. 

957 

53983  958 
* Introduced type classes order_top and order_bot. The old classes top 
959 
and bot only contain the syntax without assumptions. INCOMPATIBILITY: 

960 
Rename bot > order_bot, top > order_top 

53683  961 

53160  962 
* Introduce type classes "no_top" and "no_bot" for orderings without 
963 
top and bottom elements.

51732  973 

974 
 continuous and continuos_on from Multivariate_Analysis: 

53983  975 
"continuous" is the continuity of a function at a filter. "isCont"

977 

978

979 
arbitrary filter. 

980 

981

in tendsto_intros (or FDERIV_intros) are also available as 

1011 
tendsto_eq_intros (or FDERIV_eq_intros) where the righthand side

*** Prover IDE  Isabelle/Scala/jEdit *** 
1240 

1241 
* Parallel terminal proofs ('by') are enabled by default, likewise 

1242 
proofs that are built into packages like 'datatype', 'function'. This 

1243 
allows to "run ahead" checking the theory specifications on the 

1244 
surface, while the prover is still crunching on internal 

1245 
justifications. Unfinished / cancelled proofs are restarted as 

1246 
required to complete full proof checking eventually. 

1247 

1248 
* Improved output panel with tooltips, hyperlinks etc. based on the 

1249 
same Rich_Text_Area as regular Isabelle/jEdit buffers. Activation of 

1250 
tooltips leads to some window that supports the same recursively, 

1251 
which can lead to stacks of tooltips as the semantic document content 

1252 
is explored. ESCAPE closes the whole stack, individual windows may be 

1253 
closed separately, or detached to become independent jEdit dockables. 

1254 

50717  1255 
* Improved support for commands that produce graph output: the text 
1256 
message contains a clickable area to open a new instance of the graph

browser on demand. 

1258 

49968  1259 
* More robust incremental parsing of outer syntax (partial comments, 
1260 
malformed symbols). Changing the balance of open/close quotes and 

1261 
comment delimiters works more conveniently with unfinished situations 

1262 
that frequently occur in user interaction.

* Quickcheck: added an optimisation for equality premises. It is 

1347 
switched on by default, and can be switched off by setting the 

1348 
configuration quickcheck_optimise_equality to false.

1361 
* Preprocessing of the code generator rewrites set comprehensions into 

1362 
pointfree expressions.

* The SMT solver Z3 has now by default a restricted set of directly 

1365 
supported features. For the full set of features (div/mod, nonlinear 

1366 
arithmetic, datatypes/records) with potential proof reconstruction 

1367 
failures, enable the configuration option "z3_with_extensions". Minor 

1368 
INCOMPATIBILITY.

1405 
 Introduced the predicate filterlim (LIM x F. f x :> G) which 

1406 
expresses that when the input values x converge to F then the 

1407 
output f x converges to G. 

1408 

1409 
 Added filters for convergence to positive (at_top) and negative 

1410 
infinity (at_bot).
