54705  12 
* Document antiquotation @{file_unchecked} is like @{file}, but does 
13 
not check existence within the filesystem. 

14 

54732  15 
* Discontinued legacy_isub_isup, which was a temporary Isabelle/ML 
16 
workaround in Isabelle20131. The prover process no longer accepts 

17 
old identifier syntax with \<^isub> or \<^isup>.

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 

46 
* Auxiliary files ('ML_file' etc.) are managed by the Prover IDE. 

47 
Open text buffers take precedence over copies within the filesystem. 

48 

55536  49 
* Improved support for Isabelle/ML, with jEdit mode "isabelleml" for 
50 
auxiliary ML files.

52 
* Improved completion based on context information about embedded 
55716  53 
languages: keywords are only completed for outer syntax, symbols or 
54 
antiquotations for languages that support them. E.g. no symbol 

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

56 
antiquotations.

57 

55963  58 
* Semantic completions may get extended by appending a suffix of 
59 
underscores to an already recognized name, e.g. "foo_" to complete 

60 
"foo" or "foobar" if these are known in the context. The special 

61 
identifier "__" serves as a wildcard in this respect: it completes to 

62 
the full collection of names from the name space (truncated according 

63 
to the system option "completion_limit"). 

64 

54688  65 
* Document panel: simplied interaction where every single mouse click 
66 
(re)opens document via desktop environment or as jEdit buffer. 

67 

54881  68 
* Option "jedit_print_mode" (see also "Plugin Options / Isabelle / 
69 
General") allows to specify additional print modes for the prover 

70 
process, without requiring oldfashioned commandline invocation of 

71 
"isabelle jedit m MODE".

55001  78 
*** Pure *** 
79 

56245  80 
* Basic constants of Pure use more conventional names and are always 
81 
qualified. Rare INCOMPATIBILITY, but with potentially serious 

82 
consequences, notably for tools in Isabelle/ML. The following 

83 
renaming needs to be applied: 

84 

85 
== ~> Pure.eq 

86 
==> ~> Pure.imp 

87 
all ~> Pure.all 

88 
TYPE ~> Pure.type 

89 
dummy_pattern ~> Pure.dummy_pattern 

90 

91 
Systematic porting works by using the following theory setup on a 

92 
*previous* Isabelle version to introduce the new name accesses for the 

93 
old constants: 

94 

95 
setup {* 

96 
fn thy => thy 

97 
> Sign.root_path 

98 
> Sign.const_alias (Binding.qualify true "Pure" @{binding eq}) "==" 

99 
> Sign.const_alias (Binding.qualify true "Pure" @{binding imp}) "==>" 

100 
> Sign.const_alias (Binding.qualify true "Pure" @{binding all}) "all" 

101 
> Sign.restore_naming thy 

102 
*} 

103 

104 
Thus ML antiquotations like @{const_name Pure.eq} may be used already. 

105 
Later the application is moved to the current Isabelle version, and 

106 
the auxiliary aliases are deleted.

55152  122 
* Obsolete attribute "standard" has been discontinued (legacy since 
123 
Isabelle2012). Potential INCOMPATIBILITY, use explicit 'for' context 

124 
where instantiations with schematic variables are intended (for 

125 
declaration commands like 'lemmas' or attributes like "of"). The 

126 
following temporary definition may help to port old applications: 

127 

128 
attribute_setup standard = 

129 
"Scan.succeed (Thm.rule_attribute (K Drule.export_without_context))" 

130 

55001  131 
* More thorough check of proof context for goal statements and 
55006  132 
attributed fact expressions (concerning background theory, declared 
133 
hyps). Potential INCOMPATIBILITY, tools need to observe standard 

134 
context discipline. See also Assumption.add_assumes and the more 

135 
primitive Thm.assume_hyps.

* More robust editing of running commands with internal forks, 

608 
e.g. nonterminating 'by' steps. 

609 

54641  610 
* More relaxed Sledgehammer panel: avoid repeated application of query 
611 
after edits surrounding the command location. 

612

* More status information about commands that are interrupted 
614 
accidentally (via physical event or Poly/ML runtime system signal, 

615 
e.g. outofmemory).

695 
same timing information is shown in the extended tooltip of the

697 
COMMAND modifier is pressed. 

51533  698 

53971  699 
* Improved dockable window "Theories": Continuous checking of proof 
700 
document (visible and required parts) may be controlled explicitly, 

701 
using check box or shortcut "C+e ENTER". Individual theory nodes may 

702 
be marked explicitly as required and checked in full, using check box 

703 
or shortcut "C+e SPACE". 

704 

54305  705 
* Improved completion mechanism, which is now managed by the 
706 
Isabelle/jEdit plugin instead of SideKick. Refined table of Isabelle 

707 
symbol abbreviations (see $ISABELLE_HOME/etc/symbols). 

708

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

712

* Improved support of various "minor modes" for Isabelle NEWS, 
715 
options, session ROOT etc., with completion and SideKick tree view. 

716 

53971  717

54032  801 
* Attibute 'code': 'code' now declares concrete and abstract code 
802 
equations uniformly. Use explicit 'code equation' and 'code abstract' 

803 
to distinguish both when desired. 

804 

805 
* Discontinued theories Code_Integer and Efficient_Nat by a more 

806 
finegrain stack of theories Code_Target_Int, Code_Binary_Nat, 

807 
Code_Target_Nat and Code_Target_Numeral. See the tutorial on code 

808 
generation for details. INCOMPATIBILITY. 

809 

810 
* Numeric types are mapped by default to target language numerals: 

811 
natural (replaces former code_numeral) and integer (replaces former 

812 
code_int). Conversions are available as integer_of_natural / 

813 
natural_of_integer / integer_of_nat / nat_of_integer (in HOL) and 

814 
Code_Numeral.integer_of_natural / Code_Numeral.natural_of_integer (in 

815 
ML). INCOMPATIBILITY. 

816 

817 
* Function package: For mutually recursive functions f and g, separate 

818 
cases rules f.cases and g.cases are generated instead of unusable 

819 
f_g.cases which exposed internal sum types. Potential INCOMPATIBILITY, 

820 
in the case that the unusable rule was used nevertheless. 

821 

822 
* Function package: For each function f, new rules f.elims are 

823 
generated, which eliminate equalities of the form "f x = t". 

824 

825 
* New command 'fun_cases' derives adhoc elimination rules for 

826 
function equations as simplified instances of f.elims, analogous to 

827 
inductive_cases. See ~~/src/HOL/ex/Fundefs.thy for some examples. 

53307  828 

54021  829 
* Lifting: 
830 
 parametrized correspondence relations are now supported: 

54378  831 
+ parametricity theorems for the raw term can be specified in 
54021  832 
the command lift_definition, which allow us to generate stronger 
833 
transfer rules 

834 
+ setup_lifting generates stronger transfer rules if parametric 

835 
correspondence relation can be generated 

836 
+ various new properties of the relator must be specified to support 

837 
parametricity 

838 
+ parametricity theorem for the Quotient relation can be specified 

839 
 setup_lifting generates domain rules for the Transfer package 

840 
 stronger reflexivity prover of respectfulness theorems for type 

841 
copies 

842 
 ===> and > are now local. The symbols can be introduced 

843 
by interpreting the locale lifting_syntax (typically in an 

844 
anonymous context) 

54378  845 
 Lifting/Transfer relevant parts of Library/Quotient_* are now in 
54021  846 
Main. Potential INCOMPATIBILITY 
847 
 new commands for restoring and deleting Lifting/Transfer context: 

848 
lifting_forget, lifting_update 

54378  849 
 the command print_quotmaps was renamed to print_quot_maps. 
54021  850 
INCOMPATIBILITY 
851 

852 
* Transfer: 

54378  853 
 better support for domains in Transfer: replace Domainp T 
54021  854 
by the actual invariant in a transferred goal 
855 
 transfer rules can have as assumptions other transfer rules 

856 
 Experimental support for transferring from the raw level to the 

857 
abstract level: Transfer.transferred attribute 

858 
 Attribute version of the transfer method: untransferred attribute 

859 

52286  860 
* Reification and reflection: 
53160  861 
 Reification is now directly available in HOLMain in structure 
862 
"Reification". 

863 
 Reflection now handles multiple lists with variables also. 

864 
 The whole reflection stack has been decomposed into conversions. 

52286  865 
INCOMPATIBILITY. 
866 

51489  867 
* Revised devices for recursive definitions over finite sets: 
868 
 Only one fundamental fold combinator on finite set remains: 

869 
Finite_Set.fold :: ('a => 'b => 'b) => 'b => 'a set => 'b 

870 
This is now identity on infinite sets.

873 
 Locales comm_monoid_set, semilattice_order_set and 

874 
semilattice_neutr_order_set for big operators on sets. 

875 
See theory Big_Operators for canonical examples. 

876 
Note that foundational constants comm_monoid_set.F and 

877 
semilattice_set.F correspond to former combinators fold_image 

878 
and fold1 respectively. These are now gone. You may use 

51490  879 
those foundational constants as substitutes, but it is 
53983  880 
preferable to interpret the above locales accordingly. 
51489  881

889 

53526  890 
* Complete_Partial_Order.admissible is defined outside the type class 
891 
ccpo, but with mandatory prefix ccpo. Admissibility theorems lose the 

892 
class predicate assumption or sort constraint when possible. 

53362  893 
INCOMPATIBILITY. 
894 

53160  895 
* Introduce type class "conditionally_complete_lattice": Like a 
896 
complete lattice but does not assume the existence of the top and 

897 
bottom elements. Allows to generalize some lemmas about reals and 

898 
extended reals. Removed SupInf and replaced it by the instantiation 

899 
of conditionally_complete_lattice for real. Renamed lemmas about 

900 
conditionallycomplete lattice from Sup_... to cSup_... and from 

901 
Inf_... to cInf_... to avoid hidding of similar complete lattice 

902 
lemmas. 

903 

904 
* Introduce type class linear_continuum as combination of 

905 
conditionallycomplete lattices and inner dense linorders which have 

906 
more than one element. INCOMPATIBILITY. 

907 

53983  908 
* Introduced type classes order_top and order_bot. The old classes top 
909 
and bot only contain the syntax without assumptions. INCOMPATIBILITY: 

910 
Rename bot > order_bot, top > order_top 

53683  911 

53160  912 
* Introduce type classes "no_top" and "no_bot" for orderings without 
913 
top and bottom elements. 

51732  914 

915 
* Split dense_linorder into inner_dense_order and no_top, no_bot. 

916 

917 
* Complex_Main: Unify and move various concepts from 

53160  918 
HOLMultivariate_Analysis to HOLComplex_Main. 
51732  919 

53983  920 
 Introduce type class (lin)order_topology and 
921 
linear_continuum_topology. Allows to generalize theorems about 

922 
limits and order. Instances are reals and extended reals. 

51732  923 

924 
 continuous and continuos_on from Multivariate_Analysis: 

53983  925 
"continuous" is the continuity of a function at a filter. "isCont" 
926 
is now an abbrevitation: "isCont x f == continuous (at _) f". 

927 

928 
Generalized continuity lemmas from isCont to continuous on an 

929 
arbitrary filter. 

930 

931 
 compact from Multivariate_Analysis. Use Bolzano's lemma to prove 

932 
compactness of closed intervals on reals. Continuous functions 

933 
attain infimum and supremum on compact sets. The inverse of a 

934 
continuous function is continuous, when the function is continuous 

935 
on a compact set.

show equivalence of properties on the neighbourhood filter of x and 
943 
on all sequences converging to x. 

944 

945 
 FDERIV: Definition of has_derivative moved to Deriv.thy. Moved 

946 
theorems from Library/FDERIV.thy to Deriv.thy and base the 

947 
definition of DERIV on FDERIV. Add variants of DERIV and FDERIV 

948 
which are restricted to sets, i.e. to represent derivatives from 

949 
left or right. 

51732  950 

951 
 Removed the withinfilter. It is replaced by the principal filter: 

952 

953 
F within X = inf F (principal X) 

954 

955 
 Introduce "at x within U" as a single constant, "at x" is now an 

956 
abbreviation for "at x within UNIV" 

957 

53983  958 
 Introduce named theorem collections tendsto_intros, 
959 
continuous_intros, continuous_on_intros and FDERIV_intros. Theorems 

960 
in tendsto_intros (or FDERIV_intros) are also available as 

961 
tendsto_eq_intros (or FDERIV_eq_intros) where the righthand side 

962 
is replaced by a congruence rule. This allows to apply them as 

963 
intro rules and then proving equivalence by the simplifier. 

51732  964 

965 
 Restructured theories in HOLComplex_Main: 

966 

967

+ Moved Ln and Log to Transcendental 

978

*** Prover IDE  Isabelle/Scala/jEdit *** 
1190 

1191 
* Parallel terminal proofs ('by') are enabled by default, likewise 

1192 
proofs that are built into packages like 'datatype', 'function'. This 

1193 
allows to "run ahead" checking the theory specifications on the 

1194 
surface, while the prover is still crunching on internal 

1195 
justifications. Unfinished / cancelled proofs are restarted as 

1196 
required to complete full proof checking eventually. 

1197 

1198 
* Improved output panel with tooltips, hyperlinks etc. based on the 

1199 
same Rich_Text_Area as regular Isabelle/jEdit buffers. Activation of 

1200 
tooltips leads to some window that supports the same recursively, 

1201 
which can lead to stacks of tooltips as the semantic document content 

1202 
is explored. ESCAPE closes the whole stack, individual windows may be 

1203 
closed separately, or detached to become independent jEdit dockables. 

1204 

50717  1205 
* Improved support for commands that produce graph output: the text 
1206 
message contains a clickable area to open a new instance of the graph 

1207 
browser on demand. 

1208 

49968  1209 
* More robust incremental parsing of outer syntax (partial comments, 
1210 
malformed symbols). Changing the balance of open/close quotes and 

1211 
comment delimiters works more conveniently with unfinished situations 

1212 
that frequently occur in user interaction.

* Class "comm_monoid_diff" formalises properties of bounded 
49388  1335 
subtraction, with natural numbers and multisets as typical instances. 
1336 

50646  1337 
* Added combinator "Option.these" with type "'a option set => 'a set". 
1338 

1339 
* Theory "Transitive_Closure": renamed lemmas 

1340 

1341 
reflcl_tranclp > reflclp_tranclp 

1342 
rtranclp_reflcl > rtranclp_reflclp 

1343 

1344 
INCOMPATIBILITY. 

1345 

1346 
* Theory "Rings": renamed lemmas (in class semiring) 

1347 

1348 
left_distrib ~> distrib_right 

1349 
right_distrib ~> distrib_left 

1350 

1351 
INCOMPATIBILITY. 

1352 

1353 
* Generalized the definition of limits: 

1354 

1355 
 Introduced the predicate filterlim (LIM x F. f x :> G) which 

1356 
expresses that when the input values x converge to F then the 

1357 
output f x converges to G. 

1358 

1359 
 Added filters for convergence to positive (at_top) and negative 

1360 
infinity (at_bot). 

1361 

1362 
 Moved infinity in the norm (at_infinity) from 

1363 
Multivariate_Analysis to Complex_Main. 

1364 

1365 
 Removed real_tendsto_inf, it is superseded by "LIM x F. f x :> 

1366 
at_top". 

1367 

1368 
INCOMPATIBILITY. 

1369 

1370 
* Theory "Library/Option_ord" provides instantiation of option type to 

1371 
lattice type classes. 

1372 

1373 
* Theory "Library/Multiset": renamed 

1374 

1375 
constant fold_mset ~> Multiset.fold 

1376 
fact fold_mset_commute ~> fold_mset_comm 

1377 

1378 
INCOMPATIBILITY. 

1379 

1380 
* Renamed theory Library/List_Prefix to Library/Sublist, with related 

1381 
changes as follows. 

1382 

1383 
 Renamed constants (and related lemmas) 

49145  1384 

1385 
prefix ~> prefixeq 

1386 
strict_prefix ~> prefix 

1387 

50646  1388 
 Replaced constant "postfix" by "suffixeq" with swapped argument 
1389 
order (i.e., "postfix xs ys" is now "suffixeq ys xs") and dropped 

1390 
old infix syntax "xs >>= ys"; use "suffixeq ys xs" instead. 

1391 
Renamed lemmas accordingly. 

1392 

1393 
 Added constant "list_hembeq" for homeomorphic embedding on 

1394 
lists. Added abbreviation "sublisteq" for special case 

1395 
"list_hembeq (op =)". 

1396 

1397 
 Theory Library/Sublist no longer provides "order" and "bot" type 

1398 
class instances for the prefix order (merely corresponding locale 

1399 
interpretations). The type class instances are now in theory 

1400 
Library/Prefix_Order. 

1401 

1402 
 The sublist relation of theory Library/Sublist_Order is now based 

1403 
on "Sublist.sublisteq". Renamed lemmas accordingly: 

50516  1404 

1405 
le_list_append_le_same_iff ~> Sublist.sublisteq_append_le_same_iff 

1406 
le_list_append_mono ~> Sublist.list_hembeq_append_mono 

1407 
le_list_below_empty ~> Sublist.list_hembeq_Nil, Sublist.list_hembeq_Nil2 

1408 
le_list_Cons_EX ~> Sublist.list_hembeq_ConsD 

1409 
le_list_drop_Cons2 ~> Sublist.sublisteq_Cons2' 

1410 
le_list_drop_Cons_neq ~> Sublist.sublisteq_Cons2_neq 

1411 
le_list_drop_Cons ~> Sublist.sublisteq_Cons' 

1412 
le_list_drop_many ~> Sublist.sublisteq_drop_many 

1413 
le_list_filter_left ~> Sublist.sublisteq_filter_left 

1414 
le_list_rev_drop_many ~> Sublist.sublisteq_rev_drop_many 

1415 
le_list_rev_take_iff ~> Sublist.sublisteq_append 

1416 
le_list_same_length ~> Sublist.sublisteq_same_length 

1417 
le_list_take_many_iff ~> Sublist.sublisteq_append'
