*** General ***
wenzelm@45593
     8
wenzelm@45614
     9
* Prover IDE (PIDE) improvements:
wenzelm@45614
    10
wenzelm@45614
    11
  - markup for bound variables
wenzelm@45614
    12
  - markup for types of term variables (e.g. displayed as tooltips)
wenzelm@46956
    13
  - support for user-defined Isar commands within the running session
wenzelm@47158
    14
  - improved support for Unicode outside original 16bit range
wenzelm@47158
    15
    e.g. glyph for \<A> (thanks to jEdit 4.5.1)
wenzelm@45614
    16
wenzelm@46485
    17
* Updated and extended reference manuals ("isar-ref" and
wenzelm@46485
    18
"implementation"); reduced remaining material in old "ref" manual.
wenzelm@46485
    19
wenzelm@45593
    20
* Rule attributes in local theory declarations (e.g. locale or class)
wenzelm@45593
    21
are now statically evaluated: the resulting theorem is stored instead
wenzelm@45593
    22
of the original expression.  INCOMPATIBILITY in rare situations, where
wenzelm@45593
    23
the historic accident of dynamic re-evaluation in interpretations
wenzelm@45593
    24
etc. was exploited.
wenzelm@45593
    25
wenzelm@45600
    26
* Commands 'lemmas' and 'theorems' allow local variables using 'for'
wenzelm@45600
    27
declaration, and results are standardized before being stored.  Thus
wenzelm@45600
    28
old-style "standard" after instantiation or composition of facts
wenzelm@45600
    29
becomes obsolete.  Minor INCOMPATIBILITY, due to potential change of
wenzelm@45600
    30
indices of schematic variables.
wenzelm@45600
    31
wenzelm@46483
    32
* Renamed some inner syntax categories:
wenzelm@46483
    33
wenzelm@46483
    34
    num ~> num_token
wenzelm@46483
    35
    xnum ~> xnum_token
wenzelm@46483
    36
    xstr ~> str_token
wenzelm@46483
    37
wenzelm@46483
    38
Minor INCOMPATIBILITY.  Note that in practice "num_const" or
wenzelm@46483
    39
"num_position" etc. are mainly used instead (which also include
wenzelm@46483
    40
position information via constraints).
wenzelm@45703
    41
wenzelm@46506
    42
* Simplified configuration options for syntax ambiguity: see
wenzelm@46512
    43
"syntax_ambiguity_warning" and "syntax_ambiguity_limit" in isar-ref
wenzelm@46512
    44
manual.  Minor INCOMPATIBILITY.
wenzelm@46506
    45
wenzelm@46959
    46
* Forward declaration of outer syntax keywords within the theory
wenzelm@46959
    47
header -- minor INCOMPATIBILITY for user-defined commands.  Allow new
wenzelm@46959
    48
commands to be used in the same theory where defined.
wenzelm@46959
    49
wenzelm@45593
    50
wenzelm@45134
    51
*** Pure ***
wenzelm@45134
    52
wenzelm@47482
    53
* Auxiliary contexts indicate block structure for specifications with
wenzelm@47482
    54
additional parameters and assumptions.  Such unnamed contexts may be
wenzelm@47482
    55
nested within other targets, like 'theory', 'locale', 'class',
wenzelm@47482
    56
'instantiation' etc.  Results from the local context are generalized
wenzelm@47482
    57
accordingly and applied to the enclosing target context.  Example:
wenzelm@47482
    58
wenzelm@47482
    59
  context
wenzelm@47482
    60
    fixes x y z :: 'a
wenzelm@47482
    61
    assumes xy: "x = y" and yz: "y = z"
wenzelm@47482
    62
  begin
wenzelm@47482
    63
wenzelm@47482
    64
  lemma my_trans: "x = z" using xy yz by simp
wenzelm@47482
    65
wenzelm@47482
    66
  end
wenzelm@47482
    67
wenzelm@47482
    68
  thm my_trans
wenzelm@47482
    69
wenzelm@47482
    70
The most basic application is to factor-out context elements of
wenzelm@47482
    71
several fixes/assumes/shows theorem statements, e.g. see
wenzelm@47482
    72
~~/src/HOL/Isar_Examples/Group_Context.thy
wenzelm@47482
    73
wenzelm@47482
    74
Any other local theory specification element works within the "context
wenzelm@47482
    75
... begin ... end" block as well.
wenzelm@47482
    76
wenzelm@47484
    77
* Bundled declarations associate attributed fact expressions with a
wenzelm@47484
    78
given name in the context.  These may be later included in other
wenzelm@47484
    79
contexts.  This allows to manage context extensions casually, without
wenzelm@47484
    80
the logical dependencies of locales and locale interpretation.
wenzelm@47484
    81
wenzelm@47484
    82
See commands 'bundle', 'include', 'including' etc. in the isar-ref
wenzelm@47484
    83
manual.
wenzelm@47484
    84
wenzelm@47427
    85
* Rule composition via attribute "OF" (or ML functions OF/MRS) is more
wenzelm@47427
    86
tolerant against multiple unifiers, as long as the final result is
wenzelm@47427
    87
unique.  (As before, rules are composed in canonical right-to-left
wenzelm@47427
    88
order to accommodate newly introduced premises.)
wenzelm@47427
    89
wenzelm@46976
    90
* Command 'definition' no longer exports the foundational "raw_def"
wenzelm@46976
    91
into the user context.  Minor INCOMPATIBILITY, may use the regular
wenzelm@46976
    92
"def" result with attribute "abs_def" to imitate the old version.
wenzelm@46976
    93
wenzelm@46903
    94
* Attribute "abs_def" turns an equation of the form "f x y == t" into
wenzelm@46903
    95
"f == %x y. t", which ensures that "simp" or "unfold" steps always
wenzelm@46903
    96
expand it.  This also works for object-logic equality.  (Formerly
wenzelm@46903
    97
undocumented feature.)
wenzelm@46903
    98
wenzelm@46493
    99
* Discontinued old "prems" fact, which used to refer to the accidental
wenzelm@47464
   100
collection of foundational premises in the context (already marked as
wenzelm@47464
   101
legacy since Isabelle2011).
wenzelm@46493
   102
wenzelm@45134
   103
* Obsolete command 'types' has been discontinued.  Use 'type_synonym'
wenzelm@45134
   104
instead.  INCOMPATIBILITY.
wenzelm@45134
   105
wenzelm@47464
   106
* Old code generator for SML and its commands 'code_module',
wenzelm@45383
   107
'code_library', 'consts_code', 'types_code' have been discontinued.
haftmann@46028
   108
Use commands of the generic code generator instead.  INCOMPATIBILITY.
wenzelm@45383
   109
wenzelm@47464
   110
* Redundant attribute "code_inline" has been discontinued. Use
wenzelm@47464
   111
"code_unfold" instead.  INCOMPATIBILITY.
wenzelm@47464
   112
wenzelm@47464
   113
* Dropped attribute "code_unfold_post" in favor of the its dual
wenzelm@47464
   114
"code_abbrev", which yields a common pattern in definitions like
haftmann@46028
   115
haftmann@46028
   116
  definition [code_abbrev]: "f = t"
haftmann@46028
   117
haftmann@46028
   118
INCOMPATIBILITY.
wenzelm@45383
   119
wenzelm@45427
   120
* Sort constraints are now propagated in simultaneous statements, just
wenzelm@45427
   121
like type constraints.  INCOMPATIBILITY in rare situations, where
wenzelm@45427
   122
distinct sorts used to be assigned accidentally.  For example:
wenzelm@45427
   123
wenzelm@45427
   124
  lemma "P (x::'a::foo)" and "Q (y::'a::bar)"  -- "now illegal"
wenzelm@45427
   125
wenzelm@45427
   126
  lemma "P (x::'a)" and "Q (y::'a::bar)"
wenzelm@47462
   127
    -- "now uniform 'a::bar instead of default sort for first occurrence (!)"
wenzelm@45427
   128
wenzelm@45427
   129
huffman@45122

*** HOL ***
huffman@45122
   131
nipkow@47495
   132
* New tutorial "Programming and Proving in Isabelle/HOL" ("prog-prove").
nipkow@47494
   133
It completely supercedes "A Tutorial Introduction to Structured Isar Proofs",
nipkow@47494
   134
which has been removed. It supercedes "Isabelle/HOL, A Proof Assistant
nipkow@47494
   135
for Higher-Order Logic" as the recommended beginners tutorial
nipkow@47494
   136
but does not cover all of the material of that old tutorial.
wenzelm@47464
   137
wenzelm@47464
   138
* Discontinued old Tutorial on Isar ("isar-overview");
wenzelm@47464
   139
wenzelm@47464
   140
* Type 'a set is now a proper type constructor (just as before
wenzelm@47464
   141
Isabelle2008).  Definitions mem_def and Collect_def have disappeared.
wenzelm@47464
   142
Non-trivial INCOMPATIBILITY.  For developments keeping predicates and
wenzelm@47464
   143
sets separate, it is often sufficient to rephrase sets S accidentally
wenzelm@47464
   144
used as predicates by "%x. x : S" and predicates P accidentally used
wenzelm@47464
   145
as sets by "{x. P x}".  Corresponding proofs in a first step should be
wenzelm@47464
   146
pruned from any tinkering with former theorems mem_def and Collect_def
wenzelm@47464
   147
as far as possible.
wenzelm@47464
   148
wenzelm@47464
   149
For developments which deliberately mixed predicates and sets, a
wenzelm@47464
   150
planning step is necessary to determine what should become a predicate
wenzelm@47464
   151
and what a set.  It can be helpful to carry out that step in
wenzelm@47464
   152
Isabelle2011-1 before jumping right into the current release.
wenzelm@47464
   153
wenzelm@47464
   154
* The representation of numerals has changed.  Datatype "num"
wenzelm@47464
   155
represents strictly positive binary numerals, along with functions
wenzelm@47464
   156
"numeral :: num => 'a" and "neg_numeral :: num => 'a" to represent
wenzelm@47464
   157
positive and negated numeric literals, respectively. (See definitions
wenzelm@47464
   158
in ~~/src/HOL/Num.thy.) Potential INCOMPATIBILITY, some user theories
wenzelm@47464
   159
may require adaptations as follows:
huffman@47108
   160
huffman@47108
   161
  - Theorems with number_ring or number_semiring constraints: These
huffman@47108
   162
    classes are gone; use comm_ring_1 or comm_semiring_1 instead.
huffman@47108
   163
huffman@47108
   164
  - Theories defining numeric types: Remove number, number_semiring,
huffman@47108
   165
    and number_ring instances. Defer all theorems about numerals until
huffman@47108
   166
    after classes one and semigroup_add have been instantiated.
huffman@47108
   167
huffman@47108
   168
  - Numeral-only simp rules: Replace each rule having a "number_of v"
huffman@47108
   169
    pattern with two copies, one for numeral and one for neg_numeral.
huffman@47108
   170
huffman@47108
   171
  - Theorems about subclasses of semiring_1 or ring_1: These classes
huffman@47108
   172
    automatically support numerals now, so more simp rules and
huffman@47108
   173
    simprocs may now apply within the proof.
huffman@47108
   174
huffman@47108
   175
  - Definitions and theorems using old constructors Pls/Min/Bit0/Bit1:
huffman@47108
   176
    Redefine using other integer operations.
huffman@47108
   177
haftmann@46834
   178
* Code generation by default implements sets as container type rather
haftmann@46834
   179
than predicates.  INCOMPATIBILITY.
haftmann@46834
   180
krauss@47265
   181
* New proof import from HOL Light: Faster, simpler, and more scalable.
krauss@47265
   182
Requires a proof bundle, which is available as an external component.
wenzelm@47464
   183
Discontinued old (and mostly dead) Importer for HOL4 and HOL Light.
krauss@47265
   184
INCOMPATIBILITY.
krauss@47264
   185
nipkow@46373
   186
* New type synonym 'a rel = ('a * 'a) set
nipkow@46373
   187
haftmann@46752
   188
* More default pred/set conversions on a couple of relation operations
wenzelm@47464
   189
and predicates.  Added powers of predicate relations.  Consolidation
wenzelm@47464
   190
of some relation theorems:
haftmann@46752
   191
haftmann@46752
   192
  converse_def ~> converse_unfold
haftmann@47549
   193

   195
  transp_def ~> transp_trans
haftmann@46752
   196
  Domain_def ~> Domain_unfold
haftmann@46752
   197
  Range_def ~> Domain_converse [symmetric]
haftmann@46752
   198
haftmann@46981
   199
Generalized theorems INF_INT_eq, INF_INT_eq2, SUP_UN_eq, SUP_UN_eq2.
haftmann@46981
   200
wenzelm@47464
   201
See theory "Relation" for examples for making use of pred/set
wenzelm@47464
   202
conversions by means of attributes "to_set" and "to_pred".
haftmann@47086
   203
haftmann@46752
   204
INCOMPATIBILITY.
haftmann@46752
   205
bulwahn@46363
   206
* Renamed facts about the power operation on relations, i.e., relpow
wenzelm@47464
   207
to match the constant's name:
wenzelm@47463

wenzelm@47463
   233
bulwahn@46363
   234
INCOMPATIBILITY.
bulwahn@46363
   235
bulwahn@47448
   236
* Theory Relation: Consolidated constant name for relation composition
wenzelm@47464
   237
and corresponding theorem names:
wenzelm@47464
   238
haftmann@47549
   239
  - Renamed constant rel_comp to relcomp.
wenzelm@47464
   240
bulwahn@47448
   241
  - Dropped abbreviation pred_comp. Use relcompp instead.
wenzelm@47464

wenzelm@45383

* New "case_product" attribute to generate a case rule doing multiple
wenzelm@45383

case distinctions at the same time.  E.g.
wenzelm@45383
   578
wenzelm@45383
   579
  list.exhaust [case_product nat.exhaust]
wenzelm@45383
   580
wenzelm@45383
   581
produces a rule which can be used to perform case distinction on both
wenzelm@45383
   582
a list and a nat.
wenzelm@45383
   583
wenzelm@47464
   584
* Theory Library/Multiset: Improved code generation of multisets.
wenzelm@47464
   585
wenzelm@47464
   586
* New diagnostic command 'find_unused_assms' to find potentially
wenzelm@47464
   587
superfluous assumptions in theorems using Quickcheck.
bulwahn@46591
   588
bulwahn@45759
   589
* Quickcheck:
wenzelm@47464
   590
bulwahn@45759
   591
  - Quickcheck returns variable assignments as counterexamples, which
bulwahn@45759
   592
    allows to reveal the underspecification of functions under test.
bulwahn@45759
   593
    For example, refuting "hd xs = x", it presents the variable
bulwahn@45759
   594
    assignment xs = [] and x = a1 as a counterexample, assuming that
bulwahn@45759
   595
    any property is false whenever "hd []" occurs in it.
wenzelm@47464
   596
bulwahn@45759
   597
    These counterexample are marked as potentially spurious, as
bulwahn@45759
   598
    Quickcheck also returns "xs = []" as a counterexample to the
bulwahn@45759
   599
    obvious theorem "hd xs = hd xs".
wenzelm@47464
   600
bulwahn@45759
   601
    After finding a potentially spurious counterexample, Quickcheck
bulwahn@45759
   602
    continues searching for genuine ones.
wenzelm@47464
   603
bulwahn@45759
   604
    By default, Quickcheck shows potentially spurious and genuine
wenzelm@47464
   605
    counterexamples. The option "genuine_only" sets quickcheck to only
wenzelm@47464
   606
    show genuine counterexamples.
bulwahn@45941
   607
bulwahn@45941
   608
  - The command 'quickcheck_generator' creates random and exhaustive
bulwahn@45941
   609
    value generators for a given type and operations.
wenzelm@47464
   610
bulwahn@45941
   611
    It generates values by using the operations as if they were
wenzelm@47463
   612
    constructors of that type.
bulwahn@46170
   613
bulwahn@46170
   614
  - Support for multisets.
bulwahn@46170
   615
bulwahn@46591
   616
  - Added "use_subtype" options.
wenzelm@47464
   617
bulwahn@47349
   618
  - Added "quickcheck_locale" configuration to specify how to process
bulwahn@47349
   619
    conjectures in a locale context.
bulwahn@47349
   620
blanchet@45398
   621
* Nitpick:
wenzelm@47464
   622
blanchet@45516
   623
  - Fixed infinite loop caused by the 'peephole_optim' option and
blanchet@45516
   624
    affecting 'rat' and 'real'.
blanchet@45516
   625
blanchet@45516
   626
* Sledgehammer:
blanchet@46409
   627
  - Added "lam_trans", "uncurry_aliases", and "minimize" options.
blanchet@45706
   628
  - Renamed "slicing" ("no_slicing") option to "slice" ("dont_slice").
blanchet@46301
   629
  - Renamed "sound" option to "strict".
blanchet@45516
   630
blanchet@45516
   631
* Metis:
blanchet@45516
   632
  - Added possibility to specify lambda translations scheme as a
blanchet@46366
   633
    parenthesized argument (e.g., "by (metis (lifting) ...)").
blanchet@45398
   634
bulwahn@47197
   635
* SMT:
bulwahn@47197
   636
  - renamed "smt_fixed" option to "smt_read_only_certificates".
wenzelm@47463
   637
blanchet@46641
   638
* Command 'try0':
blanchet@46641
   639
  - Renamed from 'try_methods'. INCOMPATIBILITY.
blanchet@46641
   640
noschinl@46888
   641
* New "eventually_elim" method as a generalized variant of the
wenzelm@47464
   642
eventually_elim* rules. Supports structured proofs.
noschinl@46888
   643
wenzelm@47413
   644
* HOL/TPTP: support to parse and import TPTP problems (all languages)

wenzelm@47463
   656
analysis.
wenzelm@47463
   657
wenzelm@47463
   658
* Much greater use of mathematical symbols.
wenzelm@47463
   659
wenzelm@47463

*** ML ***
wenzelm@45128
   664
wenzelm@46948
   665
* Antiquotation @{keyword "name"} produces a parser for outer syntax
wenzelm@46948
   666
from a minor keyword introduced via theory header declaration.
wenzelm@46948
   667
wenzelm@46961
   668
* Antiquotation @{command_spec "name"} produces the
wenzelm@46961
   669
Outer_Syntax.command_spec from a major keyword introduced via theory
wenzelm@46961
   670
header declaration; it can be passed to Outer_Syntax.command etc.
wenzelm@46961
   671
wenzelm@46916
   672
* Local_Theory.define no longer hard-wires default theorem name
wenzelm@46992
   673
"foo_def", but retains the binding as given.  If that is Binding.empty
wenzelm@46992
   674
/ Attrib.empty_binding, the result is not registered as user-level
wenzelm@46992
   675
fact.  The Local_Theory.define_internal variant allows to specify a
wenzelm@46992
   676
non-empty name (used for the foundation in the background theory),
wenzelm@46992
   677
while omitting the fact binding in the user-context.  Potential
wenzelm@46992
   678
INCOMPATIBILITY for derived definitional packages: need to specify
wenzelm@46992
   679
naming policy for primitive definitions more explicitly.
wenzelm@46916
   680
wenzelm@46497
   681
* Renamed Thm.capply to Thm.apply, and Thm.cabs to Thm.lambda in
wenzelm@46497
   682
conformance with similar operations in structure Term and Logic.
wenzelm@46497
   683
wenzelm@45592
   684
* Antiquotation @{attributes [...]} embeds attribute source
wenzelm@45592
   685
representation into the ML text, which is particularly useful with
wenzelm@45592
   686
declarations like Local_Theory.note.
wenzelm@45592
   687
wenzelm@45128
   688
* Structure Proof_Context follows standard naming scheme.  Old
wenzelm@45128
   689
ProofContext has been discontinued.  INCOMPATIBILITY.
wenzelm@45128
   690
wenzelm@45293
   691
* Refined Local_Theory.declaration {syntax, pervasive}, with subtle
wenzelm@45298
   692
change of semantics: update is applied to auxiliary local theory
wenzelm@45293
   693
context as well.
wenzelm@45293
   694
wenzelm@45620

wenzelm@41703
   724
*** General ***
wenzelm@41703
   725
wenzelm@44760
   726
* Improved Isabelle/jEdit Prover IDE (PIDE), which can be invoked as
wenzelm@44968
   727
"isabelle jedit" or "ISABELLE_HOME/Isabelle" on the command line.
wenzelm@44760
   728
wenzelm@44777
   729
  - Management of multiple theory files directly from the editor
wenzelm@44760
   730
    buffer store -- bypassing the file-system (no requirement to save
wenzelm@44760
   731
    files for checking).
wenzelm@44760
   732
wenzelm@44777
   733
  - Markup of formal entities within the text buffer, with semantic
wenzelm@44760
   734
    highlighting, tooltips and hyperlinks to jump to defining source
wenzelm@44760
   735
    positions.
wenzelm@44760
   736
wenzelm@44777
   737
  - Improved text rendering, with sub/superscripts in the source
wenzelm@44777
   738
    buffer (including support for copy/paste wrt. output panel, HTML
wenzelm@44777
   739
    theory output and other non-Isabelle text boxes).
wenzelm@44777
   740
wenzelm@44777
   741
  - Refined scheduling of proof checking and printing of results,
wenzelm@44760
   742
    based on interactive editor view.  (Note: jEdit folding and
wenzelm@44760
   743
    narrowing allows to restrict buffer perspectives explicitly.)
wenzelm@44760
   744
wenzelm@44777
   745
  - Reduced CPU performance requirements, usable on machines with few
wenzelm@44760
   746
    cores.
wenzelm@44760
   747
wenzelm@44777
   748
  - Reduced memory requirements due to pruning of unused document
wenzelm@44760
   749
    versions (garbage collection).
wenzelm@44760

   752
including some remaining limitations.
wenzelm@44760
   753
wenzelm@44800
   754
* Theory loader: source files are exclusively located via the master
wenzelm@44800
   755
directory of each theory node (where the .thy file itself resides).
wenzelm@44800
   756
The global load path (such as src/HOL/Library) has been discontinued.
wenzelm@44800
   757
Note that the path element ~~ may be used to reference theories in the
wenzelm@44800
   758
Isabelle home folder -- for instance, "~~/src/HOL/Library/FuncSet".
wenzelm@44800
   759
INCOMPATIBILITY.
wenzelm@44800
   760
wenzelm@41955
   761
* Theory loader: source files are identified by content via SHA1
wenzelm@41955
   762
digests.  Discontinued former path/modtime identification and optional
wenzelm@41955
   763
ISABELLE_FILE_IDENT plugin scripts.
wenzelm@41955
   764
wenzelm@41703
   765
* Parallelization of nested Isar proofs is subject to
wenzelm@41703
   766
Goal.parallel_proofs_threshold (default 100).  See also isabelle
wenzelm@41703
   767
usedir option -Q.
wenzelm@41703
   768
wenzelm@42669
   769
* Name space: former unsynchronized references are now proper
wenzelm@42669
   770
configuration options, with more conventional names:
wenzelm@42669
   771
wenzelm@42669
   772
  long_names   ~> names_long
wenzelm@42669
   773
  short_names  ~> names_short
wenzelm@42669
   774
  unique_names ~> names_unique
wenzelm@42669
   775
wenzelm@42669
   776
Minor INCOMPATIBILITY, need to declare options in context like this:
wenzelm@42669
   777
wenzelm@42669
   778
  declare [[names_unique = false]]
wenzelm@42358
   779
wenzelm@42502
   780
* Literal facts `prop` may contain dummy patterns, e.g. `_ = _`.  Note
wenzelm@42502
   781
that the result needs to be unique, which means fact specifications
wenzelm@42502
   782
may have to be refined after enriching a proof context.
wenzelm@42502
   783
wenzelm@44800
   784
* Attribute "case_names" has been refined: the assumptions in each case
wenzelm@44800
   785
can be named now by following the case name with [name1 name2 ...].
wenzelm@44800
   786
wenzelm@44968
   787
* Isabelle/Isar reference manual has been updated and extended:
wenzelm@44968
   788
  - "Synopsis" provides a catalog of main Isar language concepts.
wenzelm@44968
   789
  - Formal references in syntax diagrams, via @{rail} antiquotation.
wenzelm@44968
   790

* Class complete_lattice: generalized a couple of lemmas from sets;
wenzelm@44800
   800
generalized theorems INF_cong and SUP_cong.  New type classes for
wenzelm@44800
   801
complete boolean algebras and complete linear orders.  Lemmas
wenzelm@44800
   802
Inf_less_iff, less_Sup_iff, INF_less_iff, less_SUP_iff now reside in
wenzelm@44800
   803
class complete_linorder.
wenzelm@44800
   804
wenzelm@44800
   805
Changed proposition of lemmas Inf_bool_def, Sup_bool_def, Inf_fun_def,
wenzelm@44800
   806
Sup_fun_def, Inf_apply, Sup_apply.
wenzelm@44800

wenzelm@44973
   845
INCOMPATIBILITY.
wenzelm@44973
   846
wenzelm@44973

compl_sup_top, inf_idem, inf_left_idem, inf_sup_absorb, sup_idem,
wenzelm@44973

wenzelm@44973
   855
INCOMPATIBILITY.
wenzelm@44973
   856
krauss@44845
   857
* Added syntactic classes "inf" and "sup" for the respective
krauss@44845
   858
constants.  INCOMPATIBILITY: Changes in the argument order of the
krauss@44845
   859
(mostly internal) locale predicates for some derived classes.
krauss@44845
   860
wenzelm@44800
   861
* Theorem collections ball_simps and bex_simps do not contain theorems
wenzelm@44800
   862
referring to UNION any longer; these have been moved to collection
wenzelm@44800
   863
UN_ball_bex_simps.  INCOMPATIBILITY.
wenzelm@44800
   864
wenzelm@44800
   865
* Theory Archimedean_Field: floor now is defined as parameter of a
wenzelm@44800
   866
separate type class floor_ceiling.
wenzelm@44800
   867
wenzelm@44800
   868
* Theory Finite_Set: more coherent development of fold_set locales:
haftmann@42874

haftmann@42874
   870
    locale fun_left_comm ~> locale comp_fun_commute

wenzelm@44800
   872
wenzelm@44800

wenzelm@44800
   874
adjustment.  INCOMPATIBILITY.
haftmann@42874
   875
wenzelm@44800
   876

   877
accordance with standard mathematical terminology. INCOMPATIBILITY.
huffman@44081
   878
wenzelm@44800
   879
* Theory Complex_Main: The locale interpretations for the
wenzelm@44800
   880
bounded_linear and bounded_bilinear locales have been removed, in
wenzelm@44800
   881
order to reduce the number of duplicate lemmas. Users must use the
wenzelm@44800
   882
original names for distributivity theorems, potential INCOMPATIBILITY.

* Theory Complex_Main: The definition of infinite series was
wenzelm@44967
   979
generalized.  Now it is defined on the type class {topological_space,
wenzelm@44967
   980
comm_monoid_add}.  Hence it is useable also for extended real numbers.
wenzelm@42484
   981
huffman@44908
   982
* Theory Complex_Main: The complex exponential function "expi" is now
huffman@44908
   983
a type-constrained abbreviation for "exp :: complex => complex"; thus
huffman@44908
   984
several polymorphic lemmas about "exp" are now applicable to "expi".
huffman@44908
   985
wenzelm@44968
   986
* Code generation:
wenzelm@44968
   987
wenzelm@44968
   988
  - Theory Library/Code_Char_ord provides native ordering of
wenzelm@44968
   989
    characters in the target language.
wenzelm@44968
   990
wenzelm@44968
   991
  - Commands code_module and code_library are legacy, use export_code
wenzelm@44968
   992
    instead.
wenzelm@44968
   993
wenzelm@44968
   994
  - Method "evaluation" is legacy, use method "eval" instead.
wenzelm@44968
   995
wenzelm@44968
   996
  - Legacy evaluator "SML" is deactivated by default.  May be
wenzelm@44968
   997
    reactivated by the following theory command:
wenzelm@44968
   998
wenzelm@44968
   999
      setup {* Value.add_evaluator ("SML", Codegen.eval_term) *}
wenzelm@44968
  1000
wenzelm@44968
  1001
* Declare ext [intro] by default.  Rare INCOMPATIBILITY.
wenzelm@44968
  1002
wenzelm@45088
  1003
* New proof method "induction" that gives induction hypotheses the
wenzelm@45088
  1004
name "IH", thus distinguishing them from further hypotheses that come
wenzelm@45088
  1005
from rule induction.  The latter are still called "hyps".  Method
wenzelm@45088
  1006
"induction" is a thin wrapper around "induct" and follows the same
wenzelm@45088
  1007
syntax.
wenzelm@45088
  1008
wenzelm@44968
  1009
* Method "fastsimp" has been renamed to "fastforce", but "fastsimp" is
wenzelm@44968
  1010
still available as a legacy feature for some time.
wenzelm@44968
  1011
wenzelm@44968
  1012
* Nitpick:
wenzelm@44968
  1013
  - Added "need" and "total_consts" options.
wenzelm@44968
  1014
  - Reintroduced "show_skolems" option by popular demand.
wenzelm@44968
  1015
  - Renamed attribute: nitpick_def ~> nitpick_unfold.
wenzelm@44968
  1016
    INCOMPATIBILITY.
wenzelm@44968
  1017
wenzelm@44968
  1018
* Sledgehammer:
wenzelm@44968
  1019
  - Use quasi-sound (and efficient) translations by default.
wenzelm@44968
  1020
  - Added support for the following provers: E-ToFoF, LEO-II,
wenzelm@44968
  1021
    Satallax, SNARK, Waldmeister, and Z3 with TPTP syntax.
wenzelm@44968
  1022
  - Automatically preplay and minimize proofs before showing them if
wenzelm@44968
  1023
    this can be done within reasonable time.
wenzelm@44968
  1024
  - sledgehammer available_provers ~> sledgehammer supported_provers.
wenzelm@44968
  1025
    INCOMPATIBILITY.
wenzelm@44968
  1026
  - Added "preplay_timeout", "slicing", "type_enc", "sound",
wenzelm@44968
  1027
    "max_mono_iters", and "max_new_mono_instances" options.
wenzelm@44968
  1028
  - Removed "explicit_apply" and "full_types" options as well as "Full
wenzelm@44968
  1029
    Types" Proof General menu item. INCOMPATIBILITY.
wenzelm@44968
  1030
wenzelm@44968
  1031
* Metis:
wenzelm@44968
  1032
  - Removed "metisF" -- use "metis" instead. INCOMPATIBILITY.
wenzelm@44968
  1033
  - Obsoleted "metisFT" -- use "metis (full_types)" instead.
wenzelm@44968
  1034
    INCOMPATIBILITY.
wenzelm@44968
  1035
wenzelm@44968
  1036
* Command 'try':
wenzelm@44968
  1037
  - Renamed 'try_methods' and added "simp:", "intro:", "dest:", and
wenzelm@44968
  1038
    "elim:" options. INCOMPATIBILITY.
wenzelm@44968
  1039
  - Introduced 'try' that not only runs 'try_methods' but also
wenzelm@44968
  1040
    'solve_direct', 'sledgehammer', 'quickcheck', and 'nitpick'.
wenzelm@44968
  1041
wenzelm@44968
  1042
* Quickcheck:
wenzelm@44968
  1043
  - Added "eval" option to evaluate terms for the found counterexample
wenzelm@44968
  1044
    (currently only supported by the default (exhaustive) tester).
wenzelm@44968

  - Added post-processing of terms to obtain readable counterexamples
wenzelm@44968
  1046
    (currently only supported by the default (exhaustive) tester).
wenzelm@44968
  1047
  - New counterexample generator quickcheck[narrowing] enables
wenzelm@44968
  1048
    narrowing-based testing.  Requires the Glasgow Haskell compiler
wenzelm@44968

been renamed accordingly. INCOMPATIBILITY.

* Session Multivariate_Analysis: The euclidean_space type class now
wenzelm@44968
  1104
fixes a constant "Basis :: 'a set" consisting of the standard
wenzelm@44968
  1105
orthonormal basis for the type. Users now have the option of
wenzelm@44968
  1106
quantifying over this set instead of using the "basis" function, e.g.
wenzelm@44968
  1107
"ALL x:Basis. P x" vs "ALL i<DIM('a). P (basis i)".
wenzelm@44968
  1108
wenzelm@44968
  1109
* Session Multivariate_Analysis: Type "('a, 'b) cart" has been renamed
wenzelm@44968
  1110
to "('a, 'b) vec" (the syntax "'a ^ 'b" remains unaffected). Constants
wenzelm@44968
  1111
"Cart_nth" and "Cart_lambda" have been respectively renamed to
wenzelm@44968
  1112
"vec_nth" and "vec_lambda"; theorems mentioning those names have
wenzelm@44968
  1113
changed to match. Definition theorems for overloaded constants now use
wenzelm@44968
  1114
the standard "foo_vec_def" naming scheme. A few other theorems have
wenzelm@44968
  1115
been renamed as follows (INCOMPATIBILITY):
wenzelm@44968
  1116
wenzelm@44968
  1117
  Cart_eq          ~> vec_eq_iff
wenzelm@44968

  Cauchy_vector    ~> vec_CauchyI
wenzelm@44968
  1121
wenzelm@44968
  1122
* Session Multivariate_Analysis: Several duplicate theorems have been
wenzelm@44968

wenzelm@43731
  1243
* The inner syntax of sort/type/term/prop supports inlined YXML
wenzelm@43731
  1244
representations within quoted string tokens.  By encoding logical
wenzelm@43731
  1245
entities via Term_XML (in ML or Scala) concrete syntax can be
wenzelm@43731
  1246
bypassed, which is particularly useful for producing bits of text

wenzelm@42057
  1268
translations that choke on unexpected type constraints.  Positions can
wenzelm@42057
  1269
be stripped in ML translations via Syntax.strip_positions /
wenzelm@42057
  1270
Syntax.strip_positions_ast, or via the syntax constant
wenzelm@42057
  1271
"_strip_positions" within parse trees.  As last resort, positions can
wenzelm@42057
  1272
be disabled via the configuration option Syntax.positions, which is
wenzelm@42057
  1273
called "syntax_positions" in Isar attribute syntax.

  1288
pointer equality (assumes that eq relation is reflexive).
wenzelm@42403
  1289
wenzelm@42793
  1290
* Classical tactics use proper Proof.context instead of historic types
wenzelm@42793
  1291
claset/clasimpset.  Old-style declarations like addIs, addEs, addDs
wenzelm@42793
  1292
operate directly on Proof.context.  Raw type claset retains its use as
wenzelm@42793
  1293
snapshot of the classical context, which can be recovered via
wenzelm@42793
  1294
(put_claset HOL_cs) etc.  Type clasimpset has been discontinued.

* Various optional external tools are referenced more robustly and
wenzelm@44967
  1308
uniformly by explicit Isabelle settings as follows:
wenzelm@44967
  1309
wenzelm@44967
  1310
  ISABELLE_CSDP   (formerly CSDP_EXE)
wenzelm@44967
  1311
  ISABELLE_GHC    (formerly EXEC_GHC or GHC_PATH)
wenzelm@44967

wenzelm@44967
  1314
  ISABELLE_YAP    (formerly EXEC_YAP)
wenzelm@44967
  1315
wenzelm@44967
  1316
Note that automated detection from the file-system or search path has
wenzelm@44967
  1317
been discontinued.  INCOMPATIBILITY.
wenzelm@44967
  1318
wenzelm@43752
  1319
* Scala layer provides JVM method invocation service for static
wenzelm@44800
  1320
methods of type (String)String, see Invoke_Scala.method in ML.  For
wenzelm@44800
  1321
example:
wenzelm@43752
  1322
wenzelm@43752
  1323
  Invoke_Scala.method "java.lang.System.getProperty" "java.home"
wenzelm@43752
  1324
wenzelm@44967
  1325
Together with YXML.string_of_body/parse_body and XML.Encode/Decode
wenzelm@44967
  1326
this allows to pass structured values between ML and Scala.
wenzelm@44800

* The IsabelleText fonts includes some further glyphs to support the
wenzelm@44803
  1329
Prover IDE.  Potential INCOMPATIBILITY: users who happen to have
wenzelm@44803
  1330
installed a local copy (which is normally *not* required) need to
wenzelm@44803
  1331
delete or update it from ~~/lib/fonts/.

*** General ***
wenzelm@37536
  1339
wenzelm@41573
  1340
* Experimental Prover IDE based on Isabelle/Scala and jEdit (see
wenzelm@41612
  1341
src/Tools/jEdit).  This also serves as IDE for Isabelle/ML, with
wenzelm@41612
  1342
useful tooltips and hyperlinks produced from its static analysis.  The
wenzelm@41612
  1343
bundled component provides an executable Isabelle tool that can be run
wenzelm@41612
  1344
like this:
wenzelm@41612
  1345
wenzelm@41612
  1346
  Isabelle2011/bin/isabelle jedit
wenzelm@41573
  1347
wenzelm@40948
  1348
* Significantly improved Isabelle/Isar implementation manual.
wenzelm@40948
  1349
wenzelm@41594
  1350
* System settings: ISABELLE_HOME_USER now includes ISABELLE_IDENTIFIER
wenzelm@41595
  1351
(and thus refers to something like $HOME/.isabelle/Isabelle2011),
wenzelm@41594
  1352
while the default heap location within that directory lacks that extra
wenzelm@41594
  1353
suffix.  This isolates multiple Isabelle installations from each
wenzelm@41594
  1354
other, avoiding problems with old settings in new versions.
wenzelm@41594
  1355
INCOMPATIBILITY, need to copy/upgrade old user settings manually.
wenzelm@41594
  1356
wenzelm@40947
  1357
* Source files are always encoded as UTF-8, instead of old-fashioned
wenzelm@40947
  1358
ISO-Latin-1.  INCOMPATIBILITY.  Isabelle LaTeX documents might require
wenzelm@40948
  1359
the following package declarations:
wenzelm@40947
  1360
wenzelm@40947
  1361
  \usepackage[utf8]{inputenc}
wenzelm@40947
  1362
  \usepackage{textcomp}
wenzelm@40947
  1363
krauss@41440
  1364
* Explicit treatment of UTF-8 sequences as Isabelle symbols, such that
wenzelm@37536
  1365
a Unicode character is treated as a single symbol, not a sequence of
wenzelm@37536
  1366
non-ASCII bytes as before.  Since Isabelle/ML string literals may
wenzelm@37536
  1367
contain symbols without further backslash escapes, Unicode can now be
wenzelm@37536
  1368
used here as well.  Recall that Symbol.explode in ML provides a
wenzelm@37536
  1369
consistent view on symbols, while raw explode (or String.explode)
wenzelm@37536
  1370
merely give a byte-oriented representation.
wenzelm@37536
  1371
wenzelm@41594
  1372
* Theory loader: source files are primarily located via the master
wenzelm@41594
  1373
directory of each theory node (where the .thy file itself resides).
wenzelm@41594
  1374
The global load path is still partially available as legacy feature.
wenzelm@41594
  1375
Minor INCOMPATIBILITY due to subtle change in file lookup: use
wenzelm@41594
  1376
explicit paths, relatively to the theory.
wenzelm@38135
  1377
wenzelm@37939
  1378
* Special treatment of ML file names has been discontinued.
wenzelm@37939
  1379
Historically, optional extensions .ML or .sml were added on demand --
wenzelm@37939
  1380
at the cost of clarity of file dependencies.  Recall that Isabelle/ML
wenzelm@37939
  1381
files exclusively use the .ML extension.  Minor INCOMPATIBILTY.
wenzelm@37939
  1382
wenzelm@38980
  1383
* Various options that affect pretty printing etc. are now properly
wenzelm@38767
  1384
handled within the context via configuration options, instead of
wenzelm@40879
  1385
unsynchronized references or print modes.  There are both ML Config.T
wenzelm@40879
  1386

  1426
float_token.
wenzelm@40291
  1427
wenzelm@41594
  1428
* Support for real valued preferences (with approximative PGIP type):

outdated 'types', which is still available as legacy feature for some
wenzelm@41249
  1442
time.
wenzelm@41249

wenzelm@41249

ballarin@41435

* Locale interpretation commands 'interpret' and 'sublocale' accept
ballarin@41435
  1451
lists of equations to map definitions in a locale to appropriate
ballarin@41435
  1452
entities in the context of the interpretation.  The 'interpretation'
ballarin@41435
  1453
command already provided this functionality.
ballarin@41435
  1454
wenzelm@41594
  1455
* Diagnostic command 'print_dependencies' prints the locale instances
wenzelm@41594
  1456
that would be activated if the specified expression was interpreted in
wenzelm@41594
  1457
the current context.  Variant "print_dependencies!" assumes a context
wenzelm@41594
  1458
without interpretations.
ballarin@38110
  1459
ballarin@38110
  1460
* Diagnostic command 'print_interps' prints interpretations in proofs
ballarin@38110
  1461
in addition to interpretations in theories.
ballarin@38110
  1462
wenzelm@38708
  1463
* Discontinued obsolete 'global' and 'local' commands to manipulate
wenzelm@38708
  1464
the theory name space.  Rare INCOMPATIBILITY.  The ML functions
wenzelm@38708
  1465
Sign.root_path and Sign.local_path may be applied directly where this
wenzelm@38708
  1466
feature is still required for historical reasons.
wenzelm@38708
  1467
wenzelm@40948

* The "prems" fact, which refers to the accidental collection of
wenzelm@41574
  1472
foundational premises in the context, is now explicitly marked as
wenzelm@41594
  1473
legacy feature and will be discontinued soon.  Consider using "assms"
wenzelm@41594
  1474
of the head statement or reference facts by explicit names.
wenzelm@41574

* Coercive subtyping: functions can be declared as coercions and type
wenzelm@41594
  1486
inference will add them as necessary upon input of a term.  Theory
wenzelm@41594
  1487
Complex_Main declares real :: nat => real and real :: int => real as
wenzelm@41594
  1488
coercions. A coercion function f is declared like this:
wenzelm@40939
  1489
wenzelm@40939
  1490
  declare [[coercion f]]
nipkow@40866
  1491
wenzelm@41571
  1492
To lift coercions through type constructors (e.g. from nat => real to
nipkow@40866
  1493
nat list => real list), map functions can be declared, e.g.
nipkow@40866
  1494
wenzelm@40939
  1495
  declare [[coercion_map map]]
wenzelm@40939
  1496
wenzelm@40939
  1497
Currently coercion inference is activated only in theories including
wenzelm@40939
  1498
real numbers, i.e. descendants of Complex_Main.  This is controlled by
wenzelm@41020
  1499
the configuration option "coercion_enabled", e.g. it can be enabled in
wenzelm@40939
  1500
other theories like this:
wenzelm@40939
  1501
wenzelm@40939
  1502
  declare [[coercion_enabled]]
nipkow@40866

* Command 'partial_function' provides basic support for recursive
wenzelm@41571
  1505
function definitions over complete partial orders.  Concrete instances
krauss@40183
  1506
are provided for i) the option type, ii) tail recursion on arbitrary
wenzelm@41571

  1512
as [simp].  INCOMPATIBILITY.
haftmann@41398
  1513
haftmann@41398

* Datatype package: theorems generated for executable equality (class
wenzelm@41571
  1515
"eq") carry proper names and are treated as default code equations.
wenzelm@41571
  1516
wenzelm@41594
  1517
* Inductive package: now offers command 'inductive_simps' to
wenzelm@41594
  1518
automatically derive instantiated and simplified equations for
wenzelm@41594
  1519
inductive predicates, similar to 'inductive_cases'.
wenzelm@41594
  1520
wenzelm@41571
  1521
* Command 'enriched_type' allows to register properties of the
wenzelm@41571
  1522
functorial structure of types.
haftmann@39771
  1523
haftmann@39644

wenzelm@41594
  1528
languages.
wenzelm@41594
  1529
haftmann@41398
  1530
* Code generator: globbing constant expressions "*" and "Theory.*"
haftmann@41398

haftmann@41398
  1536
haftmann@41398
  1537
* Code generator: do not print function definitions for case
haftmann@41398
  1538
combinators any longer.
haftmann@41398
  1539
wenzelm@41594

src/Tools/Code/code_simp.ML and method "code_simp".
wenzelm@41571
  1542
wenzelm@41594
  1543
* Code generator for records: more idiomatic representation of record
wenzelm@40948
  1544
types.  Warning: records are not covered by ancient SML code
wenzelm@40948
  1545
generation any longer.  INCOMPATIBILITY.  In cases of need, a suitable
wenzelm@40948
  1546
rep_datatype declaration helps to succeed then:
haftmann@38537

haftmann@38537
  1548
  record 'a foo = ...
haftmann@38537

  1550
  rep_datatype foo_ext ...
haftmann@38535
  1551
wenzelm@41594
  1552
* Records: logical foundation type for records does not carry a

  1554
INCOMPATIBILITY.

* Quickcheck now by default uses exhaustive testing instead of random
wenzelm@41571
  1557
testing.  Random testing can be invoked by "quickcheck [random]",
wenzelm@41571
  1558
exhaustive testing by "quickcheck [exhaustive]".
haftmann@41398
  1559
haftmann@41398
  1560
* Quickcheck instantiates polymorphic types with small finite
haftmann@41398
  1561
datatypes by default. This enables a simple execution mechanism to
haftmann@41398
  1562
handle quantifiers and function equality over the finite datatypes.
haftmann@41398
  1563
wenzelm@41571
  1564
* Quickcheck random generator has been renamed from "code" to
wenzelm@41571
  1565
"random".  INCOMPATIBILITY.
haftmann@41398
  1566
haftmann@41398
  1567
* Quickcheck now has a configurable time limit which is set to 30
haftmann@41398
  1568
seconds by default. This can be changed by adding [timeout = n] to the
haftmann@41398
  1569
quickcheck command. The time limit for Auto Quickcheck is still set
haftmann@41398
  1570
independently.
haftmann@38461

* Proof methods "metis" and "meson" now have configuration options
wenzelm@41571
  1607
"meson_trace", "metis_trace", and "metis_verbose" that can be enabled
wenzelm@41571

boehmes@41601
  1615
* The default SMT solver Z3 must be enabled explicitly (due to
boehmes@41601
  1616
licensing issues) by setting the environment variable
wenzelm@41603
  1617
Z3_NON_COMMERCIAL in etc/settings of the component, for example.  For
wenzelm@41603
  1618
commercial applications, the SMT solver CVC3 is provided as fall-back;
wenzelm@41603
  1619
changing the SMT solver is done via the configuration option

i.e. "remote_cvc3" and "remote_z3".
wenzelm@41571
  1624
wenzelm@41571
  1625
* Added basic SMT support for datatypes, records, and typedefs using
wenzelm@41571
  1626
the oracle mode (no proofs).  Direct support of pairs has been dropped
wenzelm@41571
  1627
in exchange (pass theorems fst_conv snd_conv pair_collapse to the SMT
wenzelm@41571

  1682
haftmann@41398
  1683
* Abandoned locales equiv, congruent and congruent2 for equivalence
haftmann@41398
  1684

"Sum_Type.Plus" instead.
haftmann@41398
  1767

* Session Probability: introduced pextreal as positive extended real
wenzelm@41594
  1822
numbers.  Use pextreal as value for measures.  Introduce the
wenzelm@41594
  1823
Radon-Nikodym derivative, product spaces and Fubini's theorem for
wenzelm@41594
  1824
arbitrary sigma finite measures.  Introduces Lebesgue measure based on

  1863
Accordingly, users of the definitional package must remove any
wenzelm@41571
  1864
"default_sort rep" declarations.  INCOMPATIBILITY.
huffman@40621
  1865
huffman@41401
  1866
* The domain package (definitional mode) now supports unpointed
huffman@41401
  1867
predomain argument types, as long as they are marked 'lazy'. (Strict
wenzelm@41571
  1868
arguments must be in class "domain".) For example, the following
huffman@41401
  1869
domain definition now works:
huffman@41401
  1870
huffman@41401
  1871
  domain natlist = nil | cons (lazy "nat discr") (lazy "natlist")
huffman@41401
  1872
huffman@41401
  1873
* Theory HOLCF/Library/HOL_Cpo provides cpo and predomain class
wenzelm@41571
  1874
instances for types from main HOL: bool, nat, int, char, 'a + 'b,
wenzelm@41571
  1875
'a option, and 'a list.  Additionally, it configures fixrec and the
wenzelm@41571
  1876
domain package to work with these types.  For example:
huffman@41401
  1877
huffman@41401
  1878
  fixrec isInl :: "('a + 'b) u -> tr"
huffman@41401
  1879
    where "isInl$(up$(Inl x)) = TT" | "isInl$(up$(Inr y)) = FF"
huffman@41401
  1880
huffman@41401
  1881
  domain V = VFun (lazy "V -> V") | VCon (lazy "nat") (lazy "V list")
huffman@41401
  1882
wenzelm@41571
  1883
* The "(permissive)" option of fixrec has been replaced with a
wenzelm@41571
  1884
per-equation "(unchecked)" option. See
wenzelm@41571
  1885
src/HOL/HOLCF/Tutorial/Fixrec_ex.thy for examples. INCOMPATIBILITY.
wenzelm@41571
  1886
wenzelm@41571
  1887
* The "bifinite" class no longer fixes a constant "approx"; the class
wenzelm@41571
  1888
now just asserts that such a function exists.  INCOMPATIBILITY.
wenzelm@41571
  1889
wenzelm@41571
  1890
* Former type "alg_defl" has been renamed to "defl".  HOLCF no longer
huffman@41287
  1891
defines an embedding of type 'a defl into udom by default; instances
wenzelm@41571
  1892
of "bifinite" and "domain" classes are available in
wenzelm@41571
  1893
src/HOL/HOLCF/Library/Defl_Bifinite.thy.
wenzelm@41571
  1894
wenzelm@41571
  1895
* The syntax "REP('a)" has been replaced with "DEFL('a)".
wenzelm@41571
  1896
wenzelm@41571
  1897
* The predicate "directed" has been removed.  INCOMPATIBILITY.
wenzelm@41571

INCOMPATIBILITY.
huffman@41401
  1903
huffman@41401
  1904
* The monadic bind operator on each powerdomain has new binder syntax
wenzelm@41571
  1905
similar to sets, e.g. "\<Union>\<sharp>x\<in>xs. t" represents
wenzelm@41571
  1906
"upper_bind\<cdot>xs\<cdot>(\<Lambda> x. t)".
huffman@41401
  1907
huffman@41401
  1908
* The infix syntax for binary union on each powerdomain has changed
wenzelm@41571
  1909
from e.g. "+\<sharp>" to "\<union>\<sharp>", for consistency with set
wenzelm@41571
  1910
syntax.  INCOMPATIBILITY.
wenzelm@41571
  1911
wenzelm@41571
  1912
* The constant "UU" has been renamed to "bottom".  The syntax "UU" is
huffman@41429
  1913
still supported as an input translation.
huffman@41429
  1914
huffman@40621

* Authentic syntax for *all* logical entities (type classes, type

wenzelm@35436
  2103
correspondence between formal entities and concrete syntax.  Within

Substantial INCOMPATIBILITY concerning low-level syntax declarations

  2110
Some hints on upgrading:
wenzelm@35260
  2111
wenzelm@35260
  2112
  - Many existing uses of 'syntax' and 'translations' can be replaced
wenzelm@35436
  2113
    by more modern 'type_notation', 'notation' and 'abbreviation',
wenzelm@35436
  2114
    which are independent of this issue.
wenzelm@35260
  2115
wenzelm@35260
  2116
  - 'translations' require markup within the AST; the term syntax
wenzelm@35260
  2117
    provides the following special forms:
wenzelm@35260
  2118
wenzelm@35260
  2119
      CONST c   -- produces syntax version of constant c from context
wenzelm@35261
  2120
      XCONST c  -- literally c, checked as constant from context
wenzelm@35261
  2121
      c         -- literally c, if declared by 'syntax'
wenzelm@35261
  2122
wenzelm@35261
  2123
    Plain identifiers are treated as AST variables -- occasionally the
wenzelm@35261
  2124
    system indicates accidental variables via the error "rhs contains
wenzelm@35261
  2125
    extra variables".
wenzelm@35260
  2126
wenzelm@35436
  2127
    Type classes and type constructors are marked according to their
wenzelm@35436
  2128
    concrete syntax.  Some old translations rules need to be written
wenzelm@35436
  2129
    for the "type" category, using type constructor application
wenzelm@35436
  2130
    instead of pseudo-term application of the default category
wenzelm@35436
  2131
    "logic".
wenzelm@35436
  2132
wenzelm@35260
  2133
  - 'parse_translation' etc. in ML may use the following
wenzelm@35260
  2134
    antiquotations:
wenzelm@35260
  2135
wenzelm@35436
  2136
      @{class_syntax c}   -- type class c within parse tree / AST
wenzelm@35436
  2137
      @{term_syntax c}    -- type constructor c within parse tree / AST
wenzelm@35260
  2138
      @{const_syntax c}   -- ML version of "CONST c" above
wenzelm@35260
  2139
      @{syntax_const c}   -- literally c (checked wrt. 'syntax' declarations)
wenzelm@35260
  2140
wenzelm@35436
  2141
  - Literal types within 'typed_print_translations', i.e. those *not*
wenzelm@35436
  2142
    represented as pseudo-terms are represented verbatim.  Use @{class
wenzelm@35436
  2143
    c} or @{type_name c} here instead of the above syntax
wenzelm@35436
  2144
    antiquotations.
wenzelm@35436
  2145
wenzelm@35260
  2146
Note that old non-authentic syntax was based on unqualified base
wenzelm@35436
  2147
names, so all of the above "constant" names would coincide.  Recall
wenzelm@35436
  2148
that 'print_syntax' and ML_command "set Syntax.trace_ast" help to
wenzelm@35436
  2149
diagnose syntax problems.
wenzelm@35260
  2150
wenzelm@35351
  2151
* Type constructors admit general mixfix syntax, not just infix.
wenzelm@35351
  2152
wenzelm@36508
  2153
* Concrete syntax may be attached to local entities without a proof
wenzelm@36508
  2154
body, too.  This works via regular mixfix annotations for 'fix',
wenzelm@36508
  2155
'def', 'obtain' etc. or via the explicit 'write' command, which is
wenzelm@36508
  2156
similar to the 'notation' command in theory specifications.
wenzelm@36508
  2157
wenzelm@37351
  2158
* Discontinued unnamed infix syntax (legacy feature for many years) --
wenzelm@37351
  2159
need to specify constant name and syntax separately.  Internal ML
wenzelm@37351
  2160
datatype constructors have been renamed from InfixName to Infix etc.
wenzelm@37351
  2161
Minor INCOMPATIBILITY.
wenzelm@37351
  2162
wenzelm@37351
  2163
* Schematic theorem statements need to be explicitly markup as such,
wenzelm@37351
  2164
via commands 'schematic_lemma', 'schematic_theorem',
wenzelm@37351
  2165
'schematic_corollary'.  Thus the relevance of the proof is made
wenzelm@37351
  2166
syntactically clear, which impacts performance in a parallel or
wenzelm@37351
  2167
asynchronous interactive environment.  Minor INCOMPATIBILITY.
wenzelm@37351
  2168
wenzelm@35613
  2169
* Use of cumulative prems via "!" in some proof methods has been
wenzelm@37351
  2170
discontinued (old legacy feature).
wenzelm@35613
  2171
boehmes@35979
  2172
* References 'trace_simp' and 'debug_simp' have been replaced by
wenzelm@36857
  2173
configuration options stored in the context. Enabling tracing (the
wenzelm@36857
  2174
case of debugging is similar) in proofs works via
wenzelm@36857
  2175
wenzelm@36857
  2176
  using [[trace_simp = true]]
wenzelm@36857
  2177
wenzelm@36857
  2178
Tracing is then active for all invocations of the simplifier in
wenzelm@36857
  2179
subsequent goal refinement steps. Tracing may also still be enabled or
wenzelm@40780
  2180
disabled via the ProofGeneral settings menu.
boehmes@35979
  2181
wenzelm@36177
  2182
* Separate commands 'hide_class', 'hide_type', 'hide_const',
wenzelm@36177
  2183
'hide_fact' replace the former 'hide' KIND command.  Minor
wenzelm@36177
  2184
INCOMPATIBILITY.
wenzelm@36177
  2185
wenzelm@37298
  2186
* Improved parallelism of proof term normalization: usedir -p2 -q0 is
wenzelm@37298
  2187
more efficient than combinations with -q1 or -q2.

  2191
wenzelm@37351
  2192
* Proofterms record type-class reasoning explicitly, using the
wenzelm@37351
  2193
"unconstrain" operation internally.  This eliminates all sort
wenzelm@37351
  2194
constraints from a theorem and proof, introducing explicit
wenzelm@37351
  2195
OFCLASS-premises.  On the proof term level, this operation is
wenzelm@37351
  2196
automatically applied at theorem boundaries, such that closed proofs
wenzelm@37351
  2197
are always free of sort constraints.  INCOMPATIBILITY for tools that
wenzelm@37351
  2198
inspect proof terms.
haftmann@36147
  2199
wenzelm@35765
  2200
* Local theory specifications may depend on extra type variables that
wenzelm@35765
  2201
are not present in the result type -- arguments TYPE('a) :: 'a itself
wenzelm@35765
  2202
are added internally.  For example:
wenzelm@35765
  2203
wenzelm@35765
  2204
  definition unitary :: bool where "unitary = (ALL (x::'a) y. x = y)"
wenzelm@35765
  2205
wenzelm@37351
  2206
* Predicates of locales introduced by classes carry a mandatory
wenzelm@37351
  2207
"class" prefix.  INCOMPATIBILITY.
wenzelm@37351
  2208
wenzelm@37351
  2209
* Vacuous class specifications observe default sort.  INCOMPATIBILITY.
wenzelm@37351
  2210
wenzelm@37351
  2211
* Old 'axclass' command has been discontinued.  INCOMPATIBILITY, use
wenzelm@37351
  2212
'class' instead.
wenzelm@37351
  2213
wenzelm@37351
  2214
* Command 'code_reflect' allows to incorporate generated ML code into
wenzelm@37351
  2215
runtime environment; replaces immature code_datatype antiquotation.
wenzelm@37351
  2216
INCOMPATIBILITY.
wenzelm@37351
  2217
wenzelm@37351

wenzelm@37351
  2220
wenzelm@36857
  2221
* Code generator: details of internal data cache have no impact on the
wenzelm@36857
  2222
user space functionality any longer.
wenzelm@36857
  2223
wenzelm@37351
  2224
* Methods "unfold_locales" and "intro_locales" ignore non-locale
wenzelm@37351
  2225
subgoals.  This is more appropriate for interpretations with 'where'.
wenzelm@36857
  2226
INCOMPATIBILITY.
haftmann@34170
  2227
wenzelm@36356
  2228
* Command 'example_proof' opens an empty proof body.  This allows to
wenzelm@36356
  2229
experiment with Isar, without producing any persistent result.
wenzelm@36356
  2230
wenzelm@35413
  2231
* Commands 'type_notation' and 'no_type_notation' declare type syntax
wenzelm@35413
  2232
within a local theory context, with explicit checking of the
wenzelm@35413
  2233
constructors involved (in contrast to the raw 'syntax' versions).
wenzelm@35413
  2234
wenzelm@36178
  2235
* Commands 'types' and 'typedecl' now work within a local theory
wenzelm@36178
  2236
context -- without introducing dependencies on parameters or
wenzelm@36178
  2237
assumptions, which is not possible in Isabelle/Pure.
wenzelm@35681
  2238
wenzelm@36857

* Command 'typedef' now works within a local theory context -- without
wenzelm@37351
  2246
introducing dependencies on parameters or assumptions, which is not
wenzelm@37351
  2247
possible in Isabelle/Pure/HOL.  Note that the logical environment may
wenzelm@37351
  2248
contain multiple interpretations of local typedefs (with different
wenzelm@37351
  2249
non-emptiness proofs), even in a global theory context.
wenzelm@37351
  2250
wenzelm@37351
  2251
* New package for quotient types.  Commands 'quotient_type' and
wenzelm@37351
  2252
'quotient_definition' may be used for defining types and constants by
wenzelm@37351
  2253
quotient constructions.  An example is the type of integers created by
wenzelm@37351
  2254
quotienting pairs of natural numbers:
wenzelm@37380
  2255
wenzelm@37351
  2256
  fun
wenzelm@37380
  2257
    intrel :: "(nat * nat) => (nat * nat) => bool"

  2259
    "intrel (x, y) (u, v) = (x + v = u + y)"
wenzelm@37351
  2260
wenzelm@37380
  2261
  quotient_type int = "nat * nat" / intrel
wenzelm@37351
  2262

  2263
wenzelm@37351
  2264
  quotient_definition
wenzelm@37351

    "0::int" is "(0::nat, 0::nat)"
wenzelm@37351
  2266
wenzelm@37351
  2267
The method "lifting" can be used to lift of theorems from the
wenzelm@37351
  2268
underlying "raw" type to the quotient type.  The example
wenzelm@37351
  2269
src/HOL/Quotient_Examples/FSet.thy includes such a quotient
wenzelm@37351
  2270
construction and provides a reasoning infrastructure for finite sets.
wenzelm@37351
  2271
wenzelm@37351
  2272
* Renamed Library/Quotient.thy to Library/Quotient_Type.thy to avoid
wenzelm@37351
  2273
clash with new theory Quotient in Main HOL.
wenzelm@37351
  2274

  - classes division_ring_inverse_zero, field_inverse_zero,
wenzelm@36857
  2423
    linordered_field_inverse_zero include rule inverse 0 = 0 --

* Refined algebra theorem collections:
wenzelm@36857
  2429
  - dropped theorem group group_simps, use algebra_simps instead;
wenzelm@36857
  2430
  - dropped theorem group ring_simps, use field_simps instead;
wenzelm@36857
  2431
  - proper theorem collection field_simps subsumes former theorem
wenzelm@36857
  2432
    groups field_eq_simps and field_simps;
wenzelm@36857
  2433
  - dropped lemma eq_minus_self_iff which is a duplicate for
wenzelm@36857
  2434
    equal_neg_zero.

  2435
INCOMPATIBILITY.

  2452
replaced by the more convenient lemmas Inf_empty and Sup_empty.
wenzelm@44973
  2453
Dropped lemmas Inf_insert_simp and Sup_insert_simp, which are subsumed
wenzelm@44973
  2454
by Inf_insert and Sup_insert.  Lemmas Inf_UNIV and Sup_UNIV replace
wenzelm@44973
  2455
former Inf_Univ and Sup_Univ.  Lemmas inf_top_right and sup_bot_right

  2459
multiset order:
wenzelm@37351
  2460
wenzelm@36857
  2461
  - pointwise ordering is instance of class order with standard syntax
wenzelm@36857
  2462
    <= and <;
wenzelm@36857
  2463
  - multiset ordering has syntax <=# and <#; partial order properties
wenzelm@36857
  2464
    are provided by means of interpretation with prefix
wenzelm@36857
  2465
    multiset_order;
wenzelm@36857
  2466
  - less duplication, less historical organization of sections,
wenzelm@36857
  2467
    conversion from associations lists to multisets, rudimentary code
wenzelm@36857
  2468
    generation;
wenzelm@36857
  2469
  - use insert_DiffM2 [symmetric] instead of elem_imp_eq_diff_union,

blanchet@36929
  2527
    INCOMPATIBILITY.
blanchet@36929
  2528
  - Added user's manual ("isabelle doc sledgehammer").
blanchet@36929
  2529
  - Added option syntax and "sledgehammer_params" to customize
blanchet@36929
  2530
    Sledgehammer's behavior.  See the manual for details.
blanchet@36929
  2531
  - Modified the Isar proof reconstruction code so that it produces
blanchet@36929
  2532
    direct proofs rather than proofs by contradiction.  (This feature
blanchet@36929
  2533
    is still experimental.)
blanchet@36929
  2534
  - Made Isar proof reconstruction work for SPASS, remote ATPs, and in
blanchet@36929
  2535
    full-typed mode.
blanchet@36929
  2536
  - Added support for TPTP syntax for SPASS via the "spass_tptp" ATP.
blanchet@36929
  2537
blanchet@36928
  2538
* Nitpick:
blanchet@36928
  2539
  - Added and implemented "binary_ints" and "bits" options.
blanchet@36928
  2540
  - Added "std" option and implemented support for nonstandard models.
blanchet@36928
  2541
  - Added and implemented "finitize" option to improve the precision
blanchet@36928
  2542
    of infinite datatypes based on a monotonicity analysis.
blanchet@36928
  2543
  - Added support for quotient types.
blanchet@36928
  2544
  - Added support for "specification" and "ax_specification"
blanchet@36928
  2545
    constructs.
blanchet@36928
  2546
  - Added support for local definitions (for "function" and
blanchet@36928
  2547
    "termination" proofs).
blanchet@36928
  2548
  - Added support for term postprocessors.
blanchet@36928
  2549
  - Optimized "Multiset.multiset" and "FinFun.finfun".
blanchet@36928
  2550
  - Improved efficiency of "destroy_constrs" optimization.
blanchet@36928
  2551
  - Fixed soundness bugs related to "destroy_constrs" optimization and
blanchet@36928
  2552
    record getters.
blanchet@37272
  2553
  - Fixed soundness bug related to higher-order constructors.
blanchet@37272
  2554
  - Fixed soundness bug when "full_descrs" is enabled.
blanchet@36928
  2555
  - Improved precision of set constructs.
blanchet@37260
  2556
  - Added "atoms" option.
blanchet@36928
  2557
  - Added cache to speed up repeated Kodkod invocations on the same
blanchet@36928
  2558
    problems.
blanchet@36928
  2559
  - Renamed "MiniSatJNI", "zChaffJNI", "BerkMinAlloy", and
blanchet@36928
  2560
    "SAT4JLight" to "MiniSat_JNI", "zChaff_JNI", "BerkMin_Alloy", and
blanchet@36928
  2561
    "SAT4J_Light".  INCOMPATIBILITY.
blanchet@36928
  2562
  - Removed "skolemize", "uncurry", "sym_break", "flatten_prop",
blanchet@36928
  2563
    "sharing_depth", and "show_skolems" options.  INCOMPATIBILITY.
blanchet@37264

* Method "induct" now takes instantiations of the form t, where t is not
berghofe@37361
  2567
  a variable, as a shorthand for "x == t", where x is a fresh variable.
berghofe@37361
  2568
  If this is not intended, t has to be enclosed in parentheses.
berghofe@37361
  2569
  By default, the equalities generated by definitional instantiations
berghofe@37361
  2570
  are pre-simplified, which may cause parameters of inductive cases
berghofe@37361
  2571
  to disappear, or may even delete some of the inductive cases.
berghofe@37361
  2572
  Use "induct (no_simp)" instead of "induct" to restore the old
berghofe@37361
  2573
  behaviour. The (no_simp) option is also understood by the "cases"
berghofe@37361
  2574
  and "nominal_induct" methods, which now perform pre-simplification, too.
berghofe@37361

huffman@36828

* The domain package no longer defines the function "foo_copy" for
huffman@36828

recursive domain "foo".  The reach lemma is now stated directly in
huffman@36828
  2586
terms of "foo_take".  Lemmas and proofs that mention "foo_copy" must

* Antiquotations for basic formal entities:
wenzelm@37351
  2637
wenzelm@37351
  2638
    @{class NAME}         -- type class
wenzelm@37351
  2639
    @{class_syntax NAME}  -- syntax representation of the above
wenzelm@37351
  2640
wenzelm@37351
  2641
    @{type_name NAME}     -- logical type
wenzelm@37351
  2642
    @{type_abbrev NAME}   -- type abbreviation
wenzelm@37351
  2643
    @{nonterminal NAME}   -- type of concrete syntactic category
wenzelm@37351
  2644
    @{type_syntax NAME}   -- syntax representation of any of the above
wenzelm@37351
  2645
wenzelm@37351
  2646
    @{const_name NAME}    -- logical constant (INCOMPATIBILITY)
wenzelm@37351
  2647
    @{const_abbrev NAME}  -- abbreviated constant
wenzelm@37351

    @{const_syntax NAME}  -- syntax representation of any of the above
wenzelm@37351
  2649
wenzelm@37351
  2650
* Antiquotation @{syntax_const NAME} ensures that NAME refers to a raw
wenzelm@37351
  2651
syntax constant (cf. 'syntax' command).
wenzelm@37351
  2652
wenzelm@37351
  2653
* Antiquotation @{make_string} inlines a function to print arbitrary
wenzelm@37351
  2654
values similar to the ML toplevel.  The result is compiler dependent
wenzelm@37351
  2655
and may fall back on "?" in certain situations.
wenzelm@37351
  2656
wenzelm@37351
  2657
* Diagnostic commands 'ML_val' and 'ML_command' may refer to
wenzelm@37351
  2658
antiquotations @{Isar.state} and @{Isar.goal}.  This replaces impure
wenzelm@37351
  2659
Isar.state() and Isar.goal(), which belong to the old TTY loop and do
wenzelm@37351
  2660
not work with the asynchronous Isar document model.
wenzelm@37351
  2661
wenzelm@37351
  2662
* Configuration options now admit dynamic default values, depending on
wenzelm@37351
  2663
the context or even global references.
wenzelm@37351
  2664
wenzelm@37351
  2665
* SHA1.digest digests strings according to SHA-1 (see RFC 3174).  It
wenzelm@37351
  2666
uses an efficient external library if available (for Poly/ML).
wenzelm@37351
  2667
wenzelm@37144
  2668
* Renamed some important ML structures, while keeping the old names
wenzelm@37144
  2669
for some time as aliases within the structure Legacy:
wenzelm@37144

wenzelm@37144

  OuterKeyword  ~>  Keyword
wenzelm@37144

wenzelm@37144
  2682
Note that "open Legacy" simplifies porting of sources, but forgetting
wenzelm@37144
  2683
to remove it again will complicate porting again in the future.
wenzelm@37144

  2685
* Most operations that refer to a global context are named
wenzelm@37144
  2686
accordingly, e.g. Simplifier.global_context or
wenzelm@37144
  2687
ProofContext.init_global.  There are some situations where a global
wenzelm@37144
  2688
context actually works, but under normal circumstances one needs to
wenzelm@37144
  2689
pass the proper local context through the code!
wenzelm@37144
  2690
wenzelm@37144
  2691
* Discontinued old TheoryDataFun with its copy/init operation -- data
wenzelm@37144
  2692
needs to be pure.  Functor Theory_Data_PP retains the traditional
wenzelm@37144
  2693
Pretty.pp argument to merge, which is absent in the standard
