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is superseded by "(\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 

62440  52 

62904  53 
*** Prover IDE  Isabelle/Scala/jEdit *** 
54 

63135  55 
* Cartouche abbreviations work both for " and ` to accomodate typical 
56 
situations where old ASCII notation may be updated. 

57 

63022  58 
* IDE support for the Isabelle/Pure bootstrap process, with the 
59 
following independent stages: 

60 

61 
src/Pure/ROOT0.ML 

62 
src/Pure/ROOT.ML 

63 
src/Pure/Pure.thy 

64 
src/Pure/ML_Bootstrap.thy 

65 

66 
The ML ROOT files act like quasitheories in the context of theory 

67 
ML_Bootstrap: this allows continuous checking of all loaded ML files. 

68 
The theory files are presented with a modified header to import Pure 

69 
from the running Isabelle instance. Results from changed versions of 

70 
each stage are *not* propagated to the next stage, and isolated from the 

71 
actual Isabelle/Pure that runs the IDE itself. The sequential 

72 
dependencies of the above files are only relevant for batch build.

* Command 'define' introduces a local (nonpolymorphic) definition, with

optional abstraction over local parameters. The syntax resembles 

63043  103 
'definition' and 'obtain'. It fits better into the Isar language than

114 

63259  115 
* Proof methods may refer to the main facts via the dynamic fact 
116 
"method_facts". This is particularly useful for Eisbach method 

117 
definitions. 

118 

119 
* Eisbach provides method "use" to modify the main facts of a given 

120 
method expression, e.g. 

121 

122 
(use facts in simp) 

123 
(use facts in \<open>simp add: ...\<close>)

* Option ML_exception_debugger controls detailed exception trace via the 
413 
Poly/ML debugger. Relevant ML modules need to be compiled beforehand 

414 
with ML_file_debug, or with ML_file and option ML_debugger enabled. Note 

415 
debugger information requires consirable time and space: main 

416

* Local_Theory.restore has been renamed to Local_Theory.reset to 
419 
emphasize its disruptive impact on the cumulative context, notably the 

420 
scope of 'private' or 'qualified' names. Note that Local_Theory.reset is 

421 
only appropriate when targets are managed, e.g. starting from a global 

422 
theory and returning to it. Regular definitional packages should use 

423

424 
Local_Theory.close_target instead. Rare INCOMPATIBILITY.

550 
'ML_file_debug', 'ML_file_no_debug', 'SML_file_debug', 

551 
'SML_file_no_debug' control compilation of sources with or without 

552 
debugging information. The Debugger panel allows to set breakpoints (via 

553

554 
expressions etc. At least one Debugger view needs to be active to have 

555 
any effect on the running ML program.

559 
action "isabelle.updatestate" (shortcut S+ENTER) triggers manual 

560 
update.

563 
avoid GUI overcrowding. INCOMPATIBILITY, use the State panel instead or 

564 
enable option "editor_output_state". 

61215  565

* The text overview column (status of errors, warnings etc.) is updated 
567 
asynchronously, leading to much better editor reactivity. Moreover, the 

568 
full document node content is taken into account. The width of the 

569 
column is scaled according to the main text area font, for improved 

570 
visibility. 

571 

572 
* The main text area no longer changes its color hue in outdated 

573 
situations. The text overview column takes over the role to indicate 

574 
unfinished edits in the PIDE pipeline. This avoids flashing text display 

575 
due to adhoc updates by auxiliary GUI components, such as the State 

576 
panel.

* Command 'text_raw' has been clarified: input text is processed as in 

627

696 

60449  697 
The local assumptions are bound to the name "that". The result is 
698 
exported from context of the statement as usual. The above roughly 

60414  699 
corresponds to a raw proof block like this: 
700

710 

61733  711 
* Assumptions ('assume', 'presume') allow structured rule statements 
712 
using 'if' and 'for', similar to 'have' etc. above. For example: 

61658  713 

714 
assume result: "C x y" 

715 
if "A x" and "B y" 

716 
for x :: 'a and y :: 'a 

717 

718 
This assumes "\<And>x y::'a. A x \<Longrightarrow> B y \<Longrightarrow> C x y" and produces a general 

719 
result as usual: "A ?x \<Longrightarrow> B ?y \<Longrightarrow> C ?x ?y". 

720 

721 
Vacuous quantification in assumptions is omitted, i.e. a forcontext 

722 
only effects propositions according to actual use of variables. For 

723 
example: 

724 

725 
assume "A x" and "B y" for x and y 

726 

727 
is equivalent to: 

728 

729 
assume "\<And>x. A x" and "\<And>y. B y" 

730 

60595  731 
* The meaning of 'show' with Pure rule statements has changed: premises 
732 
are treated in the sense of 'assume', instead of 'presume'. This means, 

62205  733 
a goal like "\<And>x. A x \<Longrightarrow> B x \<Longrightarrow> C x" can be solved completely as 
734 
follows: 

60595  735 

736 
show "\<And>x. A x \<Longrightarrow> B x \<Longrightarrow> C x" 

737 

738 
or: 

739 

740 
show "C x" if "A x" "B x" for x 

741 

742 
Rare INCOMPATIBILITY, the old behaviour may be recovered as follows: 

743 

744 
show "C x" when "A x" "B x" for x 

745 

60459  746 
* New command 'consider' states rules for generalized elimination and 
747 
case splitting. This is like a toplevel statement "theorem obtains" used 

748 
within a proof body; or like a multibranch 'obtain' without activation 

749 
of the local context elements yet. 

750 

60455  751 
* Proof method "cases" allows to specify the rule as first entry of 
752 
chained facts. This is particularly useful with 'consider': 

753 

754 
consider (a) A  (b) B  (c) C <proof> 

755 
then have something 

756 
proof cases 

757 
case a 

758 
then show ?thesis <proof> 

759

760 
case b 

761 
then show ?thesis <proof> 

762

763 
case c 

764 
then show ?thesis <proof> 

765 
qed 

766 

60565  767 
* Command 'case' allows fact name and attribute specification like this: 
768 

769 
case a: (c xs) 

770 
case a [attributes]: (c xs) 

771 

772 
Facts that are introduced by invoking the case context are uniformly 

773 
qualified by "a"; the same name is used for the cumulative fact. The old 

774 
form "case (c xs) [attributes]" is no longer supported. Rare 

775 
INCOMPATIBILITY, need to adapt uses of case facts in exotic situations, 

776 
and always put attributes in front.

786 
relevant for 'using', 'including', 'supply':

* Abbreviations in type classes now carry proper sort constraint. Rare 
896 
INCOMPATIBILITY in situations where the previous misbehaviour has been 

897 
exploited.

* Refinement of userspace type system in type classes: pseudolocal 

62205  900 
operations behave more similar to abbreviations. Potential 
60347  901 
INCOMPATIBILITY in exotic situations.

*** HOL *** 
905 

62017  906 
* The 'typedef' command has been upgraded from a partially checked 
907 
"axiomatization", to a full definitional specification that takes the 

908 
global collection of overloaded constant / type definitions into 

909 
account. Type definitions with open dependencies on overloaded 

910 
definitions need to be specified as "typedef (overloaded)". This 

911 
provides extra robustness in theory construction. Rare INCOMPATIBILITY. 

912 

913 
* Qualification of various formal entities in the libraries is done more 

914 
uniformly via "context begin qualified definition ... end" instead of 

915 
oldstyle "hide_const (open) ...". Consequently, both the defined 

916 
constant and its defining fact become qualified, e.g. Option.is_none and 

917 
Option.is_none_def. Occasional INCOMPATIBILITY in applications. 

918 

919 
* Some old and rarely used ASCII replacement syntax has been removed. 

920 
INCOMPATIBILITY, standard syntax with symbols should be used instead. 

921 
The subsequent commands help to reproduce the old forms, e.g. to 

922 
simplify porting old theories: 

923 

924 
notation iff (infixr "<>" 25) 

925 

926 
notation Times (infixr "<*>" 80) 

927 

928 
type_notation Map.map (infixr "~=>" 0) 

929

930

932 

933

934 
notation FuncSet.extensional_funcset (infixr ">\<^sub>E" 60) 

935 

936 
notation Omega_Words_Fun.conc (infixr "conc" 65) 

937 

938 
notation Preorder.equiv ("op ~~") 

939 
and Preorder.equiv ("(_/ ~~ _)" [51, 51] 50) 

940 

941 
notation (in topological_space) tendsto (infixr ">" 55) 

942 
notation (in topological_space) LIMSEQ ("((_)/ > (_))" [60, 60] 60) 

943 
notation LIM ("((_)/  (_)/ > (_))" [60, 0, 60] 60) 

944 

945 
notation NSA.approx (infixl "@=" 50) 

946 
notation NSLIMSEQ ("((_)/ NS> (_))" [60, 60] 60) 

947 
notation NSLIM ("((_)/  (_)/ NS> (_))" [60, 0, 60] 60) 

948 

949 
* The alternative notation "\<Colon>" for type and sort constraints has been 

950 
removed: in LaTeX document output it looks the same as "::". 

951 
INCOMPATIBILITY, use plain "::" instead. 

952 

953 
* Commands 'inductive' and 'inductive_set' work better when names for 

954 
intro rules are omitted: the "cases" and "induct" rules no longer 

955 
declare empty case_names, but no case_names at all. This allows to use 

956 
numbered cases in proofs, without requiring method "goal_cases". 

957 

958 
* Inductive definitions ('inductive', 'coinductive', etc.) expose 

959 
lowlevel facts of the internal construction only if the option 

62093  960 
"inductive_internals" is enabled. This refers to the internal predicate 
62017  961 
definition and its monotonicity result. Rare INCOMPATIBILITY. 
962 

963 
* Recursive function definitions ('fun', 'function', 'partial_function') 

964 
expose lowlevel facts of the internal construction only if the option 

62205  965 
"function_internals" is enabled. Its internal inductive definition is 
966 
also subject to "inductive_internals". Rare INCOMPATIBILITY. 

62093  967 

968 
* BNF datatypes ('datatype', 'codatatype', etc.) expose lowlevel facts 

969 
of the internal construction only if the option "bnf_internals" is 

970 
enabled. This supersedes the former option "bnf_note_all". Rare 

971 
INCOMPATIBILITY. 

62017  972 

973 
* Combinator to represent case distinction on products is named 

974 
"case_prod", uniformly, discontinuing any input aliasses. Very popular 

975 
theorem aliasses have been retained.

* The coercions to type 'real' have been reorganised. The function 

1023 
'real' is no longer overloaded, but has type 'nat => real' and 

1024 
abbreviates of_nat for that type. Also 'real_of_int :: int => real' 

1025 
abbreviates of_int for that type. Other overloaded instances of 'real' 

1026 
have been replaced by 'real_of_ereal' and 'real_of_float'.

1080 
structure on the raw type to an abstract type defined using typedef.

* Poly/ML default platform architecture may be changed from 32bit to 
62205  1322 
64bit via system option ML_system_64. A system restart (and rebuild) is 
1323

* Poly/ML 5.6 runs natively on x86windows and x86_64windows, which 

1326 
both allow larger heap space than former x86cygwin. 

1327 

62157  1328 
* Heap images are 1015% smaller due to less wasteful persistent theory 
1329

* Command 'experiment' opens an anonymous locale context with private 
1357 
naming policy. 

1358 

59951  1359 
* Command 'notepad' requires proper nesting of begin/end and its proof 
1360 
structure in the body: 'oops' is no longer supported here. Minor 

1361 
INCOMPATIBILITY, use 'sorry' instead. 

1362 

1363 
* Command 'named_theorems' declares a dynamic fact within the context, 

1364 
together with an attribute to maintain the content incrementally. This 

1365 
supersedes functor Named_Thms in Isabelle/ML, but with a subtle change 

1366 
of semantics due to external visual order vs. internal reverse order. 

1367 

1368 
* 'find_theorems': search patterns which are abstractions are 

1369 
schematically expanded before search. Search results match the naive 

1370 
expectation more closely, particularly wrt. abbreviations.
