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

not check existence within the filesystem. 

14 

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

17

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".

*** Pure *** 
115 

56245  116 
* Basic constants of Pure use more conventional names and are always 
117 
qualified. Rare INCOMPATIBILITY, but with potentially serious 

118 
consequences, notably for tools in Isabelle/ML. The following 

119 
renaming needs to be applied: 

120 

121 
== ~> Pure.eq 

122 
==> ~> Pure.imp 

123 
all ~> Pure.all 

124 
TYPE ~> Pure.type 

125 
dummy_pattern ~> Pure.dummy_pattern 

126 

127 
Systematic porting works by using the following theory setup on a 

128 
*previous* Isabelle version to introduce the new name accesses for the 

129 
old constants: 

130 

131 
setup {* 

132 
fn thy => thy 

133 
> Sign.root_path 

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

135 
> Sign.const_alias (Binding.qualify true "Pure" @{binding imp}) "==>" 

136 
> Sign.const_alias (Binding.qualify true "Pure" @{binding all}) "all" 

137 
> Sign.restore_naming thy 

138 
*} 

139 

140 
Thus ML antiquotations like @{const_name Pure.eq} may be used already. 

141 
Later the application is moved to the current Isabelle version, and 

142 
the auxiliary aliases are deleted.

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

160 
where instantiations with schematic variables are intended (for 

161 
declaration commands like 'lemmas' or attributes like "of"). The 

162 
following temporary definition may help to port old applications: 

163 

164

165 
"Scan.succeed (Thm.rule_attribute (K Drule.export_without_context))" 

166

* More thorough check of proof context for goal statements and 
55006  168 
attributed fact expressions (concerning background theory, declared 
169 
hyps). Potential INCOMPATIBILITY, tools need to observe standard 

170 
context discipline. See also Assumption.add_assumes and the more 

171 
primitive Thm.assume_hyps.

761 
sledgehammer runs over existing document sources, independently of 

762

763 

51533  764 
* Dockable window "Timing" provides an overview of relevant command 
54332  765

766 
same timing information is shown in the extended tooltip of the 

767

768 
COMMAND modifier is pressed. 

51533  769 

53971  770 
* Improved dockable window "Theories": Continuous checking of proof 
771 
document (visible and required parts) may be controlled explicitly, 

772 
using check box or shortcut "C+e ENTER". Individual theory nodes may 

773 
be marked explicitly as required and checked in full, using check box 

774 
or shortcut "C+e SPACE". 

775 

54305  776 
* Improved completion mechanism, which is now managed by the 
777 
Isabelle/jEdit plugin instead of SideKick. Refined table of Isabelle 

778

878 
Code_Target_Nat and Code_Target_Numeral. See the tutorial on code

880 

881 
* Numeric types are mapped by default to target language numerals: 

882 
natural (replaces former code_numeral) and integer (replaces former 

883 
code_int). Conversions are available as integer_of_natural / 

884

885 
Code_Numeral.integer_of_natural / Code_Numeral.natural_of_integer (in

* Function package: For mutually recursive functions f and g, separate 

889 
cases rules f.cases and g.cases are generated instead of unusable 

890 
f_g.cases which exposed internal sum types. Potential INCOMPATIBILITY, 

891 
in the case that the unusable rule was used nevertheless. 

892 

893 
* Function package: For each function f, new rules f.elims are 

894 
generated, which eliminate equalities of the form "f x = t". 

895 

896 
* New command 'fun_cases' derives adhoc elimination rules for 

897 
function equations as simplified instances of f.elims, analogous to 

898 
inductive_cases. See ~~/src/HOL/ex/Fundefs.thy for some examples.

54021  903 
the command lift_definition, which allow us to generate stronger 
904

926

* Reification and reflection: 
53160  932 
 Reification is now directly available in HOLMain in structure 
933 
"Reification". 

934 
 Reflection now handles multiple lists with variables also. 

935 
 The whole reflection stack has been decomposed into conversions. 

52286  936

937 

51489  938 
* Revised devices for recursive definitions over finite sets: 
939

967 
complete lattice but does not assume the existence of the top and 

968 
bottom elements. Allows to generalize some lemmas about reals and 

969 
extended reals. Removed SupInf and replaced it by the instantiation 

970 
of conditionally_complete_lattice for real. Renamed lemmas about 

971 
conditionallycomplete lattice from Sup_... to cSup_... and from 

972 
Inf_... to cInf_... to avoid hidding of similar complete lattice 

973 
lemmas.

976 
conditionallycomplete lattices and inner dense linorders which have 

977 
more than one element. INCOMPATIBILITY. 

978 

53983  979

981 
Rename bot > order_bot, top > order_top 

53683  982 

53160  983

1262 
* Parallel terminal proofs ('by') are enabled by default, likewise 

1263 
proofs that are built into packages like 'datatype', 'function'. This 

1264 
allows to "run ahead" checking the theory specifications on the 

1265 
surface, while the prover is still crunching on internal 

1266 
justifications. Unfinished / cancelled proofs are restarted as 

1267 
required to complete full proof checking eventually. 

1268 

1269 
* Improved output panel with tooltips, hyperlinks etc. based on the 

1270 
same Rich_Text_Area as regular Isabelle/jEdit buffers. Activation of 

1271 
tooltips leads to some window that supports the same recursively, 

1272 
which can lead to stacks of tooltips as the semantic document content 

1273 
is explored. ESCAPE closes the whole stack, individual windows may be 

1274 
closed separately, or detached to become independent jEdit dockables. 

1275 

50717  1276

browser on demand.

* Command 'export_code': relative file names are interpreted 
1333 
relatively to master directory of current theory rather than the 

1334 
rather arbitrary current working directory. INCOMPATIBILITY.

* Discontinued obsolete attribute "COMP". Potential INCOMPATIBILITY, 
1337 
use regular rule composition via "OF" / "THEN", or explicit proof 

1338 
structure instead. Note that Isabelle/ML provides a variety of 

1339 
operators like COMP, INCR_COMP, COMP_INCR, which need to be applied 

1340 
with some care where this is really required. 

1341

* Command 'typ' supports an additional variant with explicit sort 
1343 
constraint, to infer and check the most general type conforming to a 

51063  1344 
given sort. Example (in HOL): 
48792  1345 

1346 
typ "_ * _ * bool * unit" :: finite

* Command 'locale_deps' visualizes all locales and their relations as 
1349 
a Hasse diagram.

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

1386 
supported features. For the full set of features (div/mod, nonlinear 

1387 
arithmetic, datatypes/records) with potential proof reconstruction 

1388 
failures, enable the configuration option "z3_with_extensions". Minor 

1389 
INCOMPATIBILITY.
