62969  23 
* Simplified outer syntax: uniform category "name" includes long 
24 
identifiers. Former "xname" / "nameref" / "name reference" has been 

25 
discontinued. 

26 

62807  27 
* Mixfix annotations support general block properties, with syntax 
28 
"(\<open>x=a y=b z \<dots>\<close>". Notable property names are "indent", "consistent", 

29 
"unbreakable", "markup". The existing notation "(DIGITS" is equivalent 

30 
to "(\<open>indent=DIGITS\<close>". The former notation "(00" for unbreakable blocks 

31 
is superseded by "(\<open>unbreabable\<close>"  rare INCOMPATIBILITY. 

62789  32 

62440  33 
* New symbol \<circle>, e.g. for temporal operator. 
34 

62453  35 
* Old 'header' command is no longer supported (legacy since 
36 
Isabelle2015). 

37 

63273  38 
* Command 'bundle' provides a local theory target to define a bundle 
39 
from the body of specification commands (such as 'declare', 

40 
'declaration', 'notation', 'lemmas', 'lemma'). For example: 

41 

42 
bundle foo 

43 
begin 

44 
declare a [simp] 

45 
declare b [intro] 

46 
end 

63272  47 

63282  48 
* Command 'unbundle' is like 'include', but works within a local theory 
49 
context. Unlike "context includes ... begin", the effect of 'unbundle' 

50 
on the target context persists, until different declarations are given. 

51 

63383  52 
* Proof method "blast" is more robust wrt. corner cases of Pure 
53 
statements without objectlogic judgment.

62440  55 

62904  56 
*** Prover IDE  Isabelle/Scala/jEdit *** 
57 

63135  58 
* Cartouche abbreviations work both for " and ` to accomodate typical 
59 
situations where old ASCII notation may be updated. 

60 

63022  61 
* IDE support for the Isabelle/Pure bootstrap process, with the 
62 
following independent stages: 

63 

64 
src/Pure/ROOT0.ML 

65 
src/Pure/ROOT.ML 

66 
src/Pure/Pure.thy 

67 
src/Pure/ML_Bootstrap.thy 

68 

69 
The ML ROOT files act like quasitheories in the context of theory 

70 
ML_Bootstrap: this allows continuous checking of all loaded ML files. 

71 
The theory files are presented with a modified header to import Pure 

72 
from the running Isabelle instance. Results from changed versions of 

73 
each stage are *not* propagated to the next stage, and isolated from the 

74 
actual Isabelle/Pure that runs the IDE itself. The sequential 

63307  75 
dependencies of the above files are only observed for batch build.

* The defining position of a literal fact \<open>prop\<close> is maintained more 
98 
carefully, and made accessible as hyperlink in the Prover IDE. 

99 

100 
* Commands 'finally' and 'ultimately' used to expose the result as 

101 
literal fact: this accidental behaviour has been discontinued. Rare

INCOMPATIBILITY, use more explicit means to refer to facts in Isar.

105 
better to internal axioms as singleton facts with mandatory name. Minor

INCOMPATIBILITY. 

107 

63180  108

119 
optional abstraction over local parameters. The syntax resembles 

63043  120 
'definition' and 'obtain'. It fits better into the Isar language than

old 'def', which is now a legacy feature.

62216  128 

62939  129

130 
Isabelle2016). INCOMPATIBILITY, use "standard" instead. 

131 

63259  132 
* Proof methods may refer to the main facts via the dynamic fact 
133 
"method_facts". This is particularly useful for Eisbach method 

134 
definitions. 

135 

136 
* Eisbach provides method "use" to modify the main facts of a given 

137 
method expression, e.g. 

138 

139 
(use facts in simp) 

140 
(use facts in \<open>simp add: ...\<close>)

717 
'ML_file_debug', 'ML_file_no_debug', 'SML_file_debug', 

718 
'SML_file_no_debug' control compilation of sources with or without 

719 
debugging information. The Debugger panel allows to set breakpoints (via 

720

738 

739 
* The main text area no longer changes its color hue in outdated 

740

741 
unfinished edits in the PIDE pipeline. This avoids flashing text display 

742

743

The local assumptions are bound to the name "that". The result is

corresponds to a raw proof block like this:

61733  878 
* Assumptions ('assume', 'presume') allow structured rule statements 
879 
using 'if' and 'for', similar to 'have' etc. above. For example: 

61658  880 

881 
assume result: "C x y" 

882 
if "A x" and "B y" 

883 
for x :: 'a and y :: 'a 

884 

885 
This assumes "\<And>x y::'a. A x \<Longrightarrow> B y \<Longrightarrow> C x y" and produces a general 

886 
result as usual: "A ?x \<Longrightarrow> B ?y \<Longrightarrow> C ?x ?y". 

887 

888 
Vacuous quantification in assumptions is omitted, i.e. a forcontext 

889 
only effects propositions according to actual use of variables. For 

890 
example: 

891 

892 
assume "A x" and "B y" for x and y 

893 

894 
is equivalent to: 

895 

896 
assume "\<And>x. A x" and "\<And>y. B y" 

897 

60595  898 
* The meaning of 'show' with Pure rule statements has changed: premises 
899 
are treated in the sense of 'assume', instead of 'presume'. This means, 

62205  900 
a goal like "\<And>x. A x \<Longrightarrow> B x \<Longrightarrow> C x" can be solved completely as 
901 
follows: 

60595  902 

903 
show "\<And>x. A x \<Longrightarrow> B x \<Longrightarrow> C x" 

904 

905 
or: 

906 

907 
show "C x" if "A x" "B x" for x 

908 

909 
Rare INCOMPATIBILITY, the old behaviour may be recovered as follows: 

910 

911 
show "C x" when "A x" "B x" for x 

912 

60459  913 
* New command 'consider' states rules for generalized elimination and 
914 
case splitting. This is like a toplevel statement "theorem obtains" used 

915 
within a proof body; or like a multibranch 'obtain' without activation 

916 
of the local context elements yet. 

917 

60455  918 
* Proof method "cases" allows to specify the rule as first entry of 
919 
chained facts. This is particularly useful with 'consider': 

920 

921 
consider (a) A  (b) B  (c) C <proof> 

922 
then have something 

923 
proof cases 

924 
case a 

925 
then show ?thesis <proof> 

926

927 
case b 

928 
then show ?thesis <proof> 

929

930 
case c 

931 
then show ?thesis <proof> 

932 
qed 

933 

60565  934 
* Command 'case' allows fact name and attribute specification like this: 
935 

936 
case a: (c xs) 

937 
case a [attributes]: (c xs) 

938 

939 
Facts that are introduced by invoking the case context are uniformly 

940 
qualified by "a"; the same name is used for the cumulative fact. The old 

941 
form "case (c xs) [attributes]" is no longer supported. Rare 

942 
INCOMPATIBILITY, need to adapt uses of case facts in exotic situations, 

943 
and always put attributes in front.

953 
relevant for 'using', 'including', 'supply':

* The undocumented feature of implicit cases goal1, goal2, goal3, etc. 
60617  1005 
is marked as legacy, and will be removed eventually. The proof method 
1006 
"goals" achieves a similar effect within regular Isar; often it can be

'abbreviation' is also kept for morphims that only change the involved

1031 
when working with complex locale hierarchies, because proof states are

* The 'typedef' command has been upgraded from a partially checked 
1074 
"axiomatization", to a full definitional specification that takes the 

1075 
global collection of overloaded constant / type definitions into 

1076 
account. Type definitions with open dependencies on overloaded 

1077 
definitions need to be specified as "typedef (overloaded)". This 

1078 
provides extra robustness in theory construction. Rare INCOMPATIBILITY. 

1079

* Qualification of various formal entities in the libraries is done more 

1081 
uniformly via "context begin qualified definition ... end" instead of 

1082 
oldstyle "hide_const (open) ...". Consequently, both the defined 

1083 
constant and its defining fact become qualified, e.g. Option.is_none and 

1084 
Option.is_none_def. Occasional INCOMPATIBILITY in applications.

* Some old and rarely used ASCII replacement syntax has been removed. 

1087

1115 

1116 
* The alternative notation "\<Colon>" for type and sort constraints has been 

1117 
removed: in LaTeX document output it looks the same as "::". 

1118 
INCOMPATIBILITY, use plain "::" instead. 

1119 

1120 
* Commands 'inductive' and 'inductive_set' work better when names for 

1121 
intro rules are omitted: the "cases" and "induct" rules no longer 

1122 
declare empty case_names, but no case_names at all. This allows to use 

1123 
numbered cases in proofs, without requiring method "goal_cases". 

1124 

1125 
* Inductive definitions ('inductive', 'coinductive', etc.) expose 

1126 
lowlevel facts of the internal construction only if the option 

62093  1127 
"inductive_internals" is enabled. This refers to the internal predicate 
62017  1128 
definition and its monotonicity result. Rare INCOMPATIBILITY. 
1129 

1130 
* Recursive function definitions ('fun', 'function', 'partial_function') 

1131 
expose lowlevel facts of the internal construction only if the option 

62205  1132 
"function_internals" is enabled. Its internal inductive definition is 
1133 
also subject to "inductive_internals". Rare INCOMPATIBILITY. 

62093  1134 

1135 
* BNF datatypes ('datatype', 'codatatype', etc.) expose lowlevel facts 

1136 
of the internal construction only if the option "bnf_internals" is 

1137 
enabled. This supersedes the former option "bnf_note_all". Rare 

1138

1140 
* Combinator to represent case distinction on products is named
