*** General ***
wenzelm@45593
     8
wenzelm@45614
     9
* Prover IDE (PIDE) improvements:
wenzelm@45614
    10
wenzelm@47585
    11
  - more robust Sledgehammer integration (as before the sledgehammer
wenzelm@47585
    12
    command line needs to be typed into the source buffer)
wenzelm@45614
    13
  - markup for bound variables
wenzelm@45614
    14
  - markup for types of term variables (e.g. displayed as tooltips)
wenzelm@46956
    15
  - support for user-defined Isar commands within the running session
wenzelm@47158
    16
  - improved support for Unicode outside original 16bit range
wenzelm@47158
    17
    e.g. glyph for \<A> (thanks to jEdit 4.5.1)
wenzelm@45614
    18
wenzelm@46485
    19
* Updated and extended reference manuals ("isar-ref" and
wenzelm@46485
    20
"implementation"); reduced remaining material in old "ref" manual.
wenzelm@46485
    21
wenzelm@45593
    22
* Rule attributes in local theory declarations (e.g. locale or class)
wenzelm@45593
    23
are now statically evaluated: the resulting theorem is stored instead
wenzelm@45593
    24
of the original expression.  INCOMPATIBILITY in rare situations, where
wenzelm@45593
    25
the historic accident of dynamic re-evaluation in interpretations
wenzelm@45593
    26
etc. was exploited.
wenzelm@45593
    27
wenzelm@45600
    28
* Commands 'lemmas' and 'theorems' allow local variables using 'for'
wenzelm@45600
    29
declaration, and results are standardized before being stored.  Thus
wenzelm@45600
    30
old-style "standard" after instantiation or composition of facts
wenzelm@45600
    31
becomes obsolete.  Minor INCOMPATIBILITY, due to potential change of
wenzelm@45600
    32
indices of schematic variables.
wenzelm@45600
    33
wenzelm@46483
    34
* Renamed some inner syntax categories:
wenzelm@46483
    35
wenzelm@46483
    36
    num ~> num_token
wenzelm@46483
    37
    xnum ~> xnum_token
wenzelm@46483
    38
    xstr ~> str_token
wenzelm@46483
    39
wenzelm@46483
    40
Minor INCOMPATIBILITY.  Note that in practice "num_const" or
wenzelm@46483
    41
"num_position" etc. are mainly used instead (which also include
wenzelm@46483
    42
position information via constraints).
wenzelm@45703
    43
wenzelm@46506
    44
* Simplified configuration options for syntax ambiguity: see
wenzelm@46512
    45
"syntax_ambiguity_warning" and "syntax_ambiguity_limit" in isar-ref
wenzelm@46512
    46
manual.  Minor INCOMPATIBILITY.
wenzelm@46506
    47
wenzelm@46959
    48
* Forward declaration of outer syntax keywords within the theory
wenzelm@46959
    49
header -- minor INCOMPATIBILITY for user-defined commands.  Allow new
wenzelm@46959
    50
commands to be used in the same theory where defined.
wenzelm@46959
    51
wenzelm@45593

wenzelm@45134
    53
*** Pure ***
wenzelm@45134
    54
wenzelm@47482
    55
* Auxiliary contexts indicate block structure for specifications with
wenzelm@47482
    56
additional parameters and assumptions.  Such unnamed contexts may be
wenzelm@47482
    57
nested within other targets, like 'theory', 'locale', 'class',
wenzelm@47482
    58
'instantiation' etc.  Results from the local context are generalized
wenzelm@47482
    59
accordingly and applied to the enclosing target context.  Example:
wenzelm@47482
    60
wenzelm@47482
    61
  context
wenzelm@47482
    62
    fixes x y z :: 'a
wenzelm@47482
    63
    assumes xy: "x = y" and yz: "y = z"
wenzelm@47482
    64
  begin
wenzelm@47482
    65
wenzelm@47482
    66
  lemma my_trans: "x = z" using xy yz by simp
wenzelm@47482
    67
wenzelm@47482
    68
  end
wenzelm@47482
    69
wenzelm@47482
    70
  thm my_trans
wenzelm@47482
    71
wenzelm@47482
    72
The most basic application is to factor-out context elements of
wenzelm@47482
    73
several fixes/assumes/shows theorem statements, e.g. see
wenzelm@47482
    74
~~/src/HOL/Isar_Examples/Group_Context.thy
wenzelm@47482
    75
wenzelm@47482
    76
Any other local theory specification element works within the "context
wenzelm@47482
    77
... begin ... end" block as well.
wenzelm@47482
    78
wenzelm@47484
    79
* Bundled declarations associate attributed fact expressions with a
wenzelm@47484
    80
given name in the context.  These may be later included in other
wenzelm@47484
    81
contexts.  This allows to manage context extensions casually, without
wenzelm@47484
    82
the logical dependencies of locales and locale interpretation.
wenzelm@47484
    83
wenzelm@47484
    84
See commands 'bundle', 'include', 'including' etc. in the isar-ref
wenzelm@47484
    85
manual.
wenzelm@47484
    86
wenzelm@47427
    87
* Rule composition via attribute "OF" (or ML functions OF/MRS) is more
wenzelm@47427
    88
tolerant against multiple unifiers, as long as the final result is
wenzelm@47427
    89
unique.  (As before, rules are composed in canonical right-to-left
wenzelm@47427
    90
order to accommodate newly introduced premises.)
wenzelm@47427
    91
wenzelm@46976
    92
* Command 'definition' no longer exports the foundational "raw_def"
wenzelm@46976
    93
into the user context.  Minor INCOMPATIBILITY, may use the regular
wenzelm@46976
    94
"def" result with attribute "abs_def" to imitate the old version.
wenzelm@46976
    95
wenzelm@46903
    96
* Attribute "abs_def" turns an equation of the form "f x y == t" into
wenzelm@46903
    97
"f == %x y. t", which ensures that "simp" or "unfold" steps always
wenzelm@46903
    98
expand it.  This also works for object-logic equality.  (Formerly
wenzelm@46903
    99
undocumented feature.)
wenzelm@46903
   100
wenzelm@46493
   101
* Discontinued old "prems" fact, which used to refer to the accidental
wenzelm@47464
   102
collection of foundational premises in the context (already marked as
wenzelm@47464
   103
legacy since Isabelle2011).
wenzelm@46493
   104
wenzelm@45134
   105
* Obsolete command 'types' has been discontinued.  Use 'type_synonym'
wenzelm@45134
   106
instead.  INCOMPATIBILITY.
wenzelm@45134
   107
wenzelm@47464
   108
* Old code generator for SML and its commands 'code_module',
wenzelm@45383
   109
'code_library', 'consts_code', 'types_code' have been discontinued.
haftmann@46028
   110
Use commands of the generic code generator instead.  INCOMPATIBILITY.
wenzelm@45383
   111
wenzelm@47464
   112
* Redundant attribute "code_inline" has been discontinued. Use
wenzelm@47464
   113
"code_unfold" instead.  INCOMPATIBILITY.
wenzelm@47464
   114
wenzelm@47464
   115
* Dropped attribute "code_unfold_post" in favor of the its dual
wenzelm@47464
   116
"code_abbrev", which yields a common pattern in definitions like
haftmann@46028
   117
haftmann@46028
   118
  definition [code_abbrev]: "f = t"
haftmann@46028
   119
haftmann@46028
   120
INCOMPATIBILITY.
wenzelm@45383
   121
wenzelm@45427
   122
* Sort constraints are now propagated in simultaneous statements, just
wenzelm@45427
   123
like type constraints.  INCOMPATIBILITY in rare situations, where
wenzelm@45427
   124
distinct sorts used to be assigned accidentally.  For example:
wenzelm@45427
   125
wenzelm@45427
   126
  lemma "P (x::'a::foo)" and "Q (y::'a::bar)"  -- "now illegal"
wenzelm@45427
   127
wenzelm@45427
   128
  lemma "P (x::'a)" and "Q (y::'a::bar)"
wenzelm@47462
   129
    -- "now uniform 'a::bar instead of default sort for first occurrence (!)"
wenzelm@45427
   130
wenzelm@45427

*** HOL ***
huffman@45122
   133
nipkow@47495
   134
* New tutorial "Programming and Proving in Isabelle/HOL" ("prog-prove").
nipkow@47494
   135
It completely supercedes "A Tutorial Introduction to Structured Isar Proofs",
nipkow@47494
   136
which has been removed. It supercedes "Isabelle/HOL, A Proof Assistant
nipkow@47494
   137
for Higher-Order Logic" as the recommended beginners tutorial
nipkow@47494
   138
but does not cover all of the material of that old tutorial.
wenzelm@47464
   139
wenzelm@47464
   140
* Discontinued old Tutorial on Isar ("isar-overview");
wenzelm@47464
   141
wenzelm@47464
   142
* Type 'a set is now a proper type constructor (just as before
wenzelm@47464
   143
Isabelle2008).  Definitions mem_def and Collect_def have disappeared.
wenzelm@47464
   144
Non-trivial INCOMPATIBILITY.  For developments keeping predicates and
wenzelm@47464
   145
sets separate, it is often sufficient to rephrase sets S accidentally
wenzelm@47464
   146
used as predicates by "%x. x : S" and predicates P accidentally used
wenzelm@47464
   147
as sets by "{x. P x}".  Corresponding proofs in a first step should be
wenzelm@47464
   148
pruned from any tinkering with former theorems mem_def and Collect_def
wenzelm@47464
   149
as far as possible.
wenzelm@47464
   150
wenzelm@47464
   151
For developments which deliberately mixed predicates and sets, a
wenzelm@47464
   152
planning step is necessary to determine what should become a predicate
wenzelm@47464
   153
and what a set.  It can be helpful to carry out that step in
wenzelm@47464
   154
Isabelle2011-1 before jumping right into the current release.
wenzelm@47464
   155
wenzelm@47464
   156
* The representation of numerals has changed.  Datatype "num"
wenzelm@47464
   157
represents strictly positive binary numerals, along with functions
wenzelm@47464
   158
"numeral :: num => 'a" and "neg_numeral :: num => 'a" to represent
wenzelm@47464
   159
positive and negated numeric literals, respectively. (See definitions
wenzelm@47464
   160
in ~~/src/HOL/Num.thy.) Potential INCOMPATIBILITY, some user theories
wenzelm@47464
   161
may require adaptations as follows:
huffman@47108
   162
huffman@47108
   163
  - Theorems with number_ring or number_semiring constraints: These
huffman@47108
   164
    classes are gone; use comm_ring_1 or comm_semiring_1 instead.
huffman@47108
   165
huffman@47108
   166
  - Theories defining numeric types: Remove number, number_semiring,
huffman@47108
   167
    and number_ring instances. Defer all theorems about numerals until
huffman@47108
   168
    after classes one and semigroup_add have been instantiated.
huffman@47108
   169
huffman@47108
   170
  - Numeral-only simp rules: Replace each rule having a "number_of v"
huffman@47108
   171
    pattern with two copies, one for numeral and one for neg_numeral.
huffman@47108
   172
huffman@47108
   173
  - Theorems about subclasses of semiring_1 or ring_1: These classes
huffman@47108
   174
    automatically support numerals now, so more simp rules and
huffman@47108
   175
    simprocs may now apply within the proof.
huffman@47108
   176
huffman@47108
   177
  - Definitions and theorems using old constructors Pls/Min/Bit0/Bit1:
huffman@47108
   178
    Redefine using other integer operations.
huffman@47108
   179
haftmann@46834
   180
* Code generation by default implements sets as container type rather
haftmann@46834
   181
than predicates.  INCOMPATIBILITY.
haftmann@46834
   182
krauss@47265
   183
* New proof import from HOL Light: Faster, simpler, and more scalable.
krauss@47265
   184
Requires a proof bundle, which is available as an external component.
wenzelm@47464
   185
Discontinued old (and mostly dead) Importer for HOL4 and HOL Light.
krauss@47265
   186
INCOMPATIBILITY.
krauss@47264
   187
nipkow@46373
   188
* New type synonym 'a rel = ('a * 'a) set
nipkow@46373
   189
haftmann@46752
   190
* More default pred/set conversions on a couple of relation operations
wenzelm@47464
   191
and predicates.  Added powers of predicate relations.  Consolidation
wenzelm@47464
   192
of some relation theorems:
haftmann@46752
   193
haftmann@46752
   194
  converse_def ~> converse_unfold
haftmann@47549
   195

   197
  transp_def ~> transp_trans
haftmann@46752
   198
  Domain_def ~> Domain_unfold
haftmann@46752
   199
  Range_def ~> Domain_converse [symmetric]
haftmann@46752
   200
haftmann@46981
   201
Generalized theorems INF_INT_eq, INF_INT_eq2, SUP_UN_eq, SUP_UN_eq2.
haftmann@46981
   202
wenzelm@47464
   203
See theory "Relation" for examples for making use of pred/set
wenzelm@47464
   204
conversions by means of attributes "to_set" and "to_pred".
haftmann@47086
   205
haftmann@46752
   206
INCOMPATIBILITY.
haftmann@46752
   207
bulwahn@46363
   208
* Renamed facts about the power operation on relations, i.e., relpow
wenzelm@47464
   209
to match the constant's name:
wenzelm@47463
   210

bulwahn@46363
   223

  single_valued_rel_pow ~> single_valued_relpow
wenzelm@47463
   235
bulwahn@46363
   236
INCOMPATIBILITY.
bulwahn@46363
   237
bulwahn@47448
   238
* Theory Relation: Consolidated constant name for relation composition
wenzelm@47464
   239
and corresponding theorem names:
wenzelm@47464
   240
haftmann@47549
   241
  - Renamed constant rel_comp to relcomp.
wenzelm@47464
   242
bulwahn@47448
   243
  - Dropped abbreviation pred_comp. Use relcompp instead.
wenzelm@47464

bulwahn@47448
   245
  - Renamed theorems:
wenzelm@47464

wenzelm@45383

huffman@47655
   660
* New Transfer package:
huffman@47655
   661
huffman@47655
   662
  - transfer_rule attribute: Maintains a collection of transfer rules,
huffman@47655
   663
    which relate constants at two different types. Transfer rules may
huffman@47655
   664
    relate different type instances of the same polymorphic constant,
huffman@47655
   665
    or they may relate an operation on a raw type to a corresponding
huffman@47655
   666
    operation on an abstract type (quotient or subtype). For example:
huffman@47655
   667
huffman@47655
   668
    ((A ===> B) ===> list_all2 A ===> list_all2 B) map map
huffman@47655
   669
    (cr_int ===> cr_int ===> cr_int) (%(x,y) (u,v). (x+u, y+v)) plus_int
huffman@47655
   670
huffman@47655
   671
  - transfer method: Replaces a subgoal on abstract types with an
huffman@47655
   672
    equivalent subgoal on the corresponding raw types. Constants are
huffman@47655
   673
    replaced with corresponding ones according to the transfer rules.
huffman@47655
   674
    Goals are generalized over all free variables by default; this is
huffman@47655
   675
    necessary for variables whose types changes, but can be overridden
huffman@47655
   676
    for specific variables with e.g. 'transfer fixing: x y z'.
huffman@47659
   677
    The variant transfer' method allows replacing a subgoal with
huffman@47659
   678
    one that is logically stronger (rather than equivalent).
huffman@47655
   679
huffman@47655
   680
  - relator_eq attribute: Collects identity laws for relators of
huffman@47655
   681
    various type constructors, e.g. "list_all2 (op =) = (op =)". The
huffman@47655
   682
    transfer method uses these lemmas to infer transfer rules for
huffman@47655
   683
    non-polymorphic constants on the fly.
huffman@47655
   684
huffman@47655
   685
  - transfer_prover method: Assists with proving a transfer rule for a
huffman@47655
   686
    new constant, provided the constant is defined in terms of other
huffman@47655
   687
    constants that already have transfer rules. It should be applied
huffman@47655
   688
    after unfolding the constant definitions.

huffman@47655
   693
* New Lifting package:
huffman@47655
   694
huffman@47655
   695
  - lift_definition command: Defines operations on an abstract type in
huffman@47655
   696
    terms of a corresponding operation on a representation type. Example
huffman@47655
   697
    syntax:
huffman@47655
   698
huffman@47655
   699
    lift_definition dlist_insert :: "'a => 'a dlist => 'a dlist"
huffman@47655
   700
      is List.insert
huffman@47655
   701
huffman@47655
   702
    Users must discharge a respectfulness proof obligation when each
huffman@47655
   703
    constant is defined. (For a type copy, i.e. a typedef with UNIV,
huffman@47655
   704
    the proof is discharged automatically.) The obligation is
huffman@47655
   705
    presented in a user-friendly, readable form; a respectfulness
huffman@47655
   706
    theorem in the standard format and a transfer rule are generated
huffman@47655
   707
    by the package.
huffman@47655
   708
huffman@47655
   709
  - Integration with code_abstype: For typedefs (e.g. subtypes
huffman@47655
   710
    corresponding to a datatype invariant, such as dlist),
huffman@47655
   711
    lift_definition generates a code certificate theorem and sets up
huffman@47655
   712
    code generation for each constant.
huffman@47655
   713
huffman@47655
   714
  - setup_lifting command: Sets up the Lifting package to work with
huffman@47655
   715
    a user-defined type. The user must provide either a quotient
huffman@47655
   716
    theorem or a type_definition theorem. The package configures
huffman@47655
   717
    transfer rules for equality and quantifiers on the type, and sets
huffman@47655
   718
    up the lift_definition command to work with the type.
huffman@47655
   719
huffman@47655
   720
  - Usage examples: See Quotient_Examples/Lift_DList.thy,
huffman@47655
   721

   722
    Library/Float.thy.
huffman@47655
   723
huffman@47655
   724
* Quotient package:
huffman@47655
   725
huffman@47655
   726
  - The 'quotient_type' command now supports a 'morphisms' option with
huffman@47655
   727
    rep and abs functions, similar to typedef.
huffman@47655
   728
huffman@47655
   729
  - 'quotient_type' sets up new types to work with the Lifting and
huffman@47655
   730
    Transfer packages, as with 'setup_lifting'.
huffman@47655
   731
huffman@47655
   732
  - The 'quotient_definition' command now requires the user to prove a
huffman@47655
   733
    respectfulness property at the point where the constant is
huffman@47659
   734
    defined, similar to lift_definition; INCOMPATIBILITY.
huffman@47655
   735
huffman@47655
   736
  - Renamed predicate 'Quotient' to 'Quotient3', and renamed theorems
huffman@47655
   737
    accordingly, INCOMPATIBILITY.
huffman@47655
   738
wenzelm@47464
   739
* New diagnostic command 'find_unused_assms' to find potentially
wenzelm@47464
   740
superfluous assumptions in theorems using Quickcheck.
bulwahn@46591
   741
bulwahn@45759
   742
* Quickcheck:
wenzelm@47464
   743
bulwahn@45759
   744
  - Quickcheck returns variable assignments as counterexamples, which
bulwahn@45759
   745
    allows to reveal the underspecification of functions under test.
bulwahn@45759
   746
    For example, refuting "hd xs = x", it presents the variable
bulwahn@45759
   747
    assignment xs = [] and x = a1 as a counterexample, assuming that
bulwahn@45759
   748
    any property is false whenever "hd []" occurs in it.
wenzelm@47464
   749
bulwahn@45759
   750
    These counterexample are marked as potentially spurious, as
bulwahn@45759
   751
    Quickcheck also returns "xs = []" as a counterexample to the
bulwahn@45759
   752
    obvious theorem "hd xs = hd xs".
wenzelm@47464
   753
bulwahn@45759
   754
    After finding a potentially spurious counterexample, Quickcheck
bulwahn@45759
   755
    continues searching for genuine ones.
wenzelm@47464
   756
bulwahn@45759
   757
    By default, Quickcheck shows potentially spurious and genuine
wenzelm@47464
   758
    counterexamples. The option "genuine_only" sets quickcheck to only
wenzelm@47464
   759
    show genuine counterexamples.
bulwahn@45941
   760
bulwahn@45941
   761
  - The command 'quickcheck_generator' creates random and exhaustive
bulwahn@45941
   762
    value generators for a given type and operations.
wenzelm@47464
   763
bulwahn@45941
   764
    It generates values by using the operations as if they were
wenzelm@47463
   765
    constructors of that type.
bulwahn@46170
   766
bulwahn@46170
   767
  - Support for multisets.
bulwahn@46170
   768
bulwahn@46591
   769
  - Added "use_subtype" options.
wenzelm@47464

bulwahn@47349
   771
  - Added "quickcheck_locale" configuration to specify how to process
bulwahn@47349
   772
    conjectures in a locale context.
bulwahn@47349
   773
blanchet@45398
   774
* Nitpick:
blanchet@45516
   775
  - Fixed infinite loop caused by the 'peephole_optim' option and
blanchet@45516
   776
    affecting 'rat' and 'real'.
blanchet@45516
   777
blanchet@45516
   778
* Sledgehammer:
blanchet@47563
   779
  - Integrated more tightly with SPASS, as described in the ITP 2012 paper "More
blanchet@47563
   780
    SPASS with Isabelle".
blanchet@47563
   781
  - Made it try "smt" as a fallback if "metis" fails or times out.
blanchet@47563
   782
  - Added support for the following provers: Alt-Ergo (via Why3 and TFF1),
blanchet@47563
   783
    iProver, iProver-Eq.
blanchet@47563
   784
  - Replaced remote E-SInE with remote Satallax in the default setup.
blanchet@47563
   785
  - Sped up the minimizer.
blanchet@46409
   786
  - Added "lam_trans", "uncurry_aliases", and "minimize" options.
blanchet@45706
   787
  - Renamed "slicing" ("no_slicing") option to "slice" ("dont_slice").
blanchet@46301
   788
  - Renamed "sound" option to "strict".
blanchet@45516
   789
blanchet@45516
   790
* Metis:
blanchet@45516
   791
  - Added possibility to specify lambda translations scheme as a
blanchet@46366
   792
    parenthesized argument (e.g., "by (metis (lifting) ...)").
blanchet@45398
   793
bulwahn@47197
   794
* SMT:
blanchet@47563
   795
  - Renamed "smt_fixed" option to "smt_read_only_certificates".
wenzelm@47463
   796
blanchet@46641
   797
* Command 'try0':
blanchet@46641
   798
  - Renamed from 'try_methods'. INCOMPATIBILITY.
blanchet@46641
   799
noschinl@46888
   800
* New "eventually_elim" method as a generalized variant of the
wenzelm@47464
   801
eventually_elim* rules. Supports structured proofs.
noschinl@46888
   802
wenzelm@47413
   803
* HOL/TPTP: support to parse and import TPTP problems (all languages)
wenzelm@47464

wenzelm@47463
   815
analysis.
wenzelm@47463
   816
wenzelm@47463
   817
* Much greater use of mathematical symbols.
wenzelm@47463
   818
wenzelm@47463

*** ML ***
wenzelm@45128
   823
wenzelm@46948
   824
* Antiquotation @{keyword "name"} produces a parser for outer syntax
wenzelm@46948
   825
from a minor keyword introduced via theory header declaration.
wenzelm@46948
   826
wenzelm@46961
   827
* Antiquotation @{command_spec "name"} produces the
wenzelm@46961
   828
Outer_Syntax.command_spec from a major keyword introduced via theory
wenzelm@46961
   829
header declaration; it can be passed to Outer_Syntax.command etc.
wenzelm@46961
   830
wenzelm@46916
   831
* Local_Theory.define no longer hard-wires default theorem name
wenzelm@46992
   832
"foo_def", but retains the binding as given.  If that is Binding.empty
wenzelm@46992
   833
/ Attrib.empty_binding, the result is not registered as user-level
wenzelm@46992
   834
fact.  The Local_Theory.define_internal variant allows to specify a
wenzelm@46992
   835
non-empty name (used for the foundation in the background theory),
wenzelm@46992
   836
while omitting the fact binding in the user-context.  Potential
wenzelm@46992
   837
INCOMPATIBILITY for derived definitional packages: need to specify
wenzelm@46992
   838
naming policy for primitive definitions more explicitly.
wenzelm@46916
   839
wenzelm@46497
   840
* Renamed Thm.capply to Thm.apply, and Thm.cabs to Thm.lambda in
wenzelm@46497
   841
conformance with similar operations in structure Term and Logic.
wenzelm@46497
   842
wenzelm@45592
   843
* Antiquotation @{attributes [...]} embeds attribute source
wenzelm@45592
   844
representation into the ML text, which is particularly useful with
wenzelm@45592
   845
declarations like Local_Theory.note.
wenzelm@45592
   846
wenzelm@45128
   847
* Structure Proof_Context follows standard naming scheme.  Old
wenzelm@45128
   848
ProofContext has been discontinued.  INCOMPATIBILITY.
wenzelm@45128
   849
wenzelm@45293
   850
* Refined Local_Theory.declaration {syntax, pervasive}, with subtle
wenzelm@45298
   851
change of semantics: update is applied to auxiliary local theory
wenzelm@45293
   852
context as well.
wenzelm@45293
   853
wenzelm@45620
   854

*** System ***
wenzelm@47461
   871
wenzelm@47661
   872
* USER_HOME settings variable points to cross-platform user home
wenzelm@47661
   873
directory, which coincides with HOME on POSIX systems only.  Likewise,
wenzelm@47661
   874
the Isabelle path specification "~" now expands to $USER_HOME, instead
wenzelm@47661
   875
of former $HOME.  A different default for USER_HOME may be set
wenzelm@47661
   876
explicitly in shell environment, before Isabelle settings are
wenzelm@47661
   877
evaluated.  Minor INCOMPATIBILITY: need to adapt Isabelle path where
wenzelm@47661
   878
the generic user home was intended.
wenzelm@47661
   879
wenzelm@47464
   880
* ISABELLE_JDK_HOME settings variable points to JDK with javac and jar
wenzelm@47464
   881
(not just JRE).
wenzelm@47464
   882
wenzelm@47461
   883
* ISABELLE_HOME_WINDOWS refers to ISABELLE_HOME in windows file name
wenzelm@47461
   884
notation, which is useful for the jEdit file browser, for example.

wenzelm@41703
   891
*** General ***
wenzelm@41703
   892
wenzelm@44760
   893
* Improved Isabelle/jEdit Prover IDE (PIDE), which can be invoked as
wenzelm@44968
   894
"isabelle jedit" or "ISABELLE_HOME/Isabelle" on the command line.
wenzelm@44760
   895
wenzelm@44777
   896
  - Management of multiple theory files directly from the editor
wenzelm@44760
   897
    buffer store -- bypassing the file-system (no requirement to save
wenzelm@44760
   898
    files for checking).
wenzelm@44760
   899
wenzelm@44777
   900
  - Markup of formal entities within the text buffer, with semantic
wenzelm@44760
   901
    highlighting, tooltips and hyperlinks to jump to defining source
wenzelm@44760
   902
    positions.
wenzelm@44760
   903
wenzelm@44777
   904
  - Improved text rendering, with sub/superscripts in the source
wenzelm@44777
   905
    buffer (including support for copy/paste wrt. output panel, HTML
wenzelm@44777
   906
    theory output and other non-Isabelle text boxes).
wenzelm@44777
   907
wenzelm@44777
   908
  - Refined scheduling of proof checking and printing of results,
wenzelm@44760
   909
    based on interactive editor view.  (Note: jEdit folding and
wenzelm@44760
   910
    narrowing allows to restrict buffer perspectives explicitly.)
wenzelm@44760
   911
wenzelm@44777
   912
  - Reduced CPU performance requirements, usable on machines with few
wenzelm@44760
   913
    cores.
wenzelm@44760
   914
wenzelm@44777
   915
  - Reduced memory requirements due to pruning of unused document
wenzelm@44760
   916
    versions (garbage collection).
wenzelm@44760
   917
wenzelm@44760

   919
including some remaining limitations.
wenzelm@44760

wenzelm@44800
   921
* Theory loader: source files are exclusively located via the master
wenzelm@44800
   922
directory of each theory node (where the .thy file itself resides).
wenzelm@44800
   923
The global load path (such as src/HOL/Library) has been discontinued.
wenzelm@44800
   924
Note that the path element ~~ may be used to reference theories in the
wenzelm@44800
   925
Isabelle home folder -- for instance, "~~/src/HOL/Library/FuncSet".
wenzelm@44800
   926
INCOMPATIBILITY.
wenzelm@44800
   927
wenzelm@41955
   928
* Theory loader: source files are identified by content via SHA1
wenzelm@41955
   929
digests.  Discontinued former path/modtime identification and optional
wenzelm@41955
   930
ISABELLE_FILE_IDENT plugin scripts.
wenzelm@41955
   931
wenzelm@41703
   932
* Parallelization of nested Isar proofs is subject to
wenzelm@41703
   933
Goal.parallel_proofs_threshold (default 100).  See also isabelle
wenzelm@41703
   934
usedir option -Q.
wenzelm@41703
   935
wenzelm@42669
   936
* Name space: former unsynchronized references are now proper
wenzelm@42669
   937
configuration options, with more conventional names:
wenzelm@42669
   938
wenzelm@42669
   939
  long_names   ~> names_long
wenzelm@42669
   940
  short_names  ~> names_short
wenzelm@42669
   941
  unique_names ~> names_unique
wenzelm@42669
   942
wenzelm@42669
   943
Minor INCOMPATIBILITY, need to declare options in context like this:
wenzelm@42669
   944
wenzelm@42669
   945
  declare [[names_unique = false]]
wenzelm@42358
   946
wenzelm@42502
   947
* Literal facts `prop` may contain dummy patterns, e.g. `_ = _`.  Note
wenzelm@42502
   948
that the result needs to be unique, which means fact specifications
wenzelm@42502
   949
may have to be refined after enriching a proof context.
wenzelm@42502
   950
wenzelm@44800
   951
* Attribute "case_names" has been refined: the assumptions in each case
wenzelm@44800
   952
can be named now by following the case name with [name1 name2 ...].
wenzelm@44800
   953
wenzelm@44968
   954
* Isabelle/Isar reference manual has been updated and extended:
wenzelm@44968
   955
  - "Synopsis" provides a catalog of main Isar language concepts.
wenzelm@44968
   956
  - Formal references in syntax diagrams, via @{rail} antiquotation.
wenzelm@44968
   957
  - Updated material from classic "ref" manual, notably about

bounded_linear and bounded_bilinear locales have been removed, in
wenzelm@44800
  1048
order to reduce the number of duplicate lemmas. Users must use the
wenzelm@44800
  1049
original names for distributivity theorems, potential INCOMPATIBILITY.

* Theory Complex_Main: The definition of infinite series was
wenzelm@44967
  1146
generalized.  Now it is defined on the type class {topological_space,
wenzelm@44967
  1147
comm_monoid_add}.  Hence it is useable also for extended real numbers.
wenzelm@42484
  1148
huffman@44908
  1149
* Theory Complex_Main: The complex exponential function "expi" is now
huffman@44908
  1150
a type-constrained abbreviation for "exp :: complex => complex"; thus
huffman@44908
  1151
several polymorphic lemmas about "exp" are now applicable to "expi".
huffman@44908
  1152
wenzelm@44968
  1153
* Code generation:
wenzelm@44968
  1154
wenzelm@44968
  1155
  - Theory Library/Code_Char_ord provides native ordering of
wenzelm@44968
  1156
    characters in the target language.
wenzelm@44968
  1157
wenzelm@44968
  1158
  - Commands code_module and code_library are legacy, use export_code
wenzelm@44968
  1159
    instead.
wenzelm@44968
  1160
wenzelm@44968
  1161
  - Method "evaluation" is legacy, use method "eval" instead.
wenzelm@44968
  1162
wenzelm@44968
  1163
  - Legacy evaluator "SML" is deactivated by default.  May be
wenzelm@44968
  1164
    reactivated by the following theory command:
wenzelm@44968
  1165
wenzelm@44968
  1166
      setup {* Value.add_evaluator ("SML", Codegen.eval_term) *}
wenzelm@44968
  1167
wenzelm@44968
  1168
* Declare ext [intro] by default.  Rare INCOMPATIBILITY.
wenzelm@44968
  1169
wenzelm@45088
  1170
* New proof method "induction" that gives induction hypotheses the
wenzelm@45088
  1171
name "IH", thus distinguishing them from further hypotheses that come
wenzelm@45088
  1172
from rule induction.  The latter are still called "hyps".  Method
wenzelm@45088
  1173
"induction" is a thin wrapper around "induct" and follows the same
wenzelm@45088
  1174
syntax.
wenzelm@45088
  1175
wenzelm@44968
  1176
* Method "fastsimp" has been renamed to "fastforce", but "fastsimp" is
wenzelm@44968
  1177
still available as a legacy feature for some time.
wenzelm@44968
  1178
wenzelm@44968
  1179
* Nitpick:
wenzelm@44968
  1180
  - Added "need" and "total_consts" options.
wenzelm@44968
  1181
  - Reintroduced "show_skolems" option by popular demand.
wenzelm@44968
  1182
  - Renamed attribute: nitpick_def ~> nitpick_unfold.
wenzelm@44968
  1183
    INCOMPATIBILITY.
wenzelm@44968
  1184
wenzelm@44968
  1185
* Sledgehammer:
wenzelm@44968
  1186
  - Use quasi-sound (and efficient) translations by default.
wenzelm@44968
  1187
  - Added support for the following provers: E-ToFoF, LEO-II,
wenzelm@44968
  1188
    Satallax, SNARK, Waldmeister, and Z3 with TPTP syntax.
wenzelm@44968
  1189
  - Automatically preplay and minimize proofs before showing them if
wenzelm@44968
  1190
    this can be done within reasonable time.
wenzelm@44968
  1191
  - sledgehammer available_provers ~> sledgehammer supported_provers.
wenzelm@44968
  1192
    INCOMPATIBILITY.
wenzelm@44968
  1193
  - Added "preplay_timeout", "slicing", "type_enc", "sound",
wenzelm@44968
  1194
    "max_mono_iters", and "max_new_mono_instances" options.
wenzelm@44968
  1195
  - Removed "explicit_apply" and "full_types" options as well as "Full
wenzelm@44968
  1196
    Types" Proof General menu item. INCOMPATIBILITY.
wenzelm@44968
  1197
wenzelm@44968
  1198
* Metis:
wenzelm@44968
  1199
  - Removed "metisF" -- use "metis" instead. INCOMPATIBILITY.
wenzelm@44968
  1200
  - Obsoleted "metisFT" -- use "metis (full_types)" instead.
wenzelm@44968
  1201
    INCOMPATIBILITY.
wenzelm@44968
  1202
wenzelm@44968
  1203
* Command 'try':
wenzelm@44968
  1204
  - Renamed 'try_methods' and added "simp:", "intro:", "dest:", and
wenzelm@44968
  1205
    "elim:" options. INCOMPATIBILITY.
wenzelm@44968
  1206
  - Introduced 'try' that not only runs 'try_methods' but also
wenzelm@44968
  1207
    'solve_direct', 'sledgehammer', 'quickcheck', and 'nitpick'.
wenzelm@44968
  1208
wenzelm@44968
  1209
* Quickcheck:
wenzelm@44968
  1210
  - Added "eval" option to evaluate terms for the found counterexample
wenzelm@44968
  1211
    (currently only supported by the default (exhaustive) tester).
wenzelm@44968
  1212
  - Added post-processing of terms to obtain readable counterexamples
wenzelm@44968
  1213
    (currently only supported by the default (exhaustive) tester).
wenzelm@44968
  1214
  - New counterexample generator quickcheck[narrowing] enables
wenzelm@44968
  1215
    narrowing-based testing.  Requires the Glasgow Haskell compiler
wenzelm@44968
  1216
    with its installation location defined in the Isabelle settings
wenzelm@44968
  1217
    environment as ISABELLE_GHC.
wenzelm@44968
  1218
  - Removed quickcheck tester "SML" based on the SML code generator
wenzelm@44968
  1219
    (formly in HOL/Library).
wenzelm@44968
  1220
wenzelm@44968
  1221
* Function package: discontinued option "tailrec".  INCOMPATIBILITY,
wenzelm@44968
  1222
use 'partial_function' instead.
wenzelm@44968
  1223
wenzelm@44968
  1224
* Theory Library/Extended_Reals replaces now the positive extended
wenzelm@44968
  1225
reals found in probability theory. This file is extended by
wenzelm@44968
  1226
Multivariate_Analysis/Extended_Real_Limits.
wenzelm@44968
  1227
wenzelm@44974
  1228
* Theory Library/Old_Recdef: old 'recdef' package has been moved here,
wenzelm@44974
  1229
from where it must be imported explicitly if it is really required.
wenzelm@44974
  1230
INCOMPATIBILITY.
wenzelm@44968
  1231
wenzelm@44968
  1232
* Theory Library/Wfrec: well-founded recursion combinator "wfrec" has
wenzelm@44968
  1233
been moved here.  INCOMPATIBILITY.
wenzelm@44968
  1234
wenzelm@44968
  1235
* Theory Library/Saturated provides type of numbers with saturated
wenzelm@44968
  1236
arithmetic.
wenzelm@44968
  1237
wenzelm@44968
  1238
* Theory Library/Product_Lattice defines a pointwise ordering for the
wenzelm@44968
  1239
product type 'a * 'b, and provides instance proofs for various order
wenzelm@44968
  1240
and lattice type classes.
wenzelm@44968
  1241
wenzelm@44968
  1242
* Theory Library/Countable now provides the "countable_datatype" proof
wenzelm@44968
  1243
method for proving "countable" class instances for datatypes.
wenzelm@44968
  1244
wenzelm@44968
  1245
* Theory Library/Cset_Monad allows do notation for computable sets
wenzelm@44968
  1246
(cset) via the generic monad ad-hoc overloading facility.
wenzelm@44968
  1247
wenzelm@44968
  1248
* Library: Theories of common data structures are split into theories
wenzelm@44968
  1249
for implementation, an invariant-ensuring type, and connection to an
wenzelm@44968
  1250
abstract type. INCOMPATIBILITY.
wenzelm@44968
  1251
wenzelm@44968
  1252
  - RBT is split into RBT and RBT_Mapping.
wenzelm@44968
  1253
  - AssocList is split and renamed into AList and AList_Mapping.
wenzelm@44968
  1254
  - DList is split into DList_Impl, DList, and DList_Cset.
wenzelm@44968
  1255
  - Cset is split into Cset and List_Cset.
wenzelm@44968
  1256
wenzelm@44968
  1257
* Theory Library/Nat_Infinity has been renamed to
wenzelm@44968
  1258
Library/Extended_Nat, with name changes of the following types and
wenzelm@44968
  1259
constants:
wenzelm@44968
  1260
wenzelm@44968
  1261
  type inat   ~> type enat
wenzelm@44968
  1262
  Fin         ~> enat
wenzelm@44968
  1263
  Infty       ~> infinity (overloaded)
wenzelm@44968
  1264
  iSuc        ~> eSuc
wenzelm@44968
  1265
  the_Fin     ~> the_enat
wenzelm@44968
  1266
wenzelm@44968
  1267
Every theorem name containing "inat", "Fin", "Infty", or "iSuc" has
wenzelm@44968
  1268
been renamed accordingly. INCOMPATIBILITY.
wenzelm@44968
  1269
wenzelm@44968
  1270
* Session Multivariate_Analysis: The euclidean_space type class now
wenzelm@44968
  1271
fixes a constant "Basis :: 'a set" consisting of the standard
wenzelm@44968
  1272
orthonormal basis for the type. Users now have the option of
wenzelm@44968
  1273
quantifying over this set instead of using the "basis" function, e.g.
wenzelm@44968
  1274
"ALL x:Basis. P x" vs "ALL i<DIM('a). P (basis i)".
wenzelm@44968
  1275
wenzelm@44968
  1276
* Session Multivariate_Analysis: Type "('a, 'b) cart" has been renamed
wenzelm@44968
  1277
to "('a, 'b) vec" (the syntax "'a ^ 'b" remains unaffected). Constants
wenzelm@44968
  1278
"Cart_nth" and "Cart_lambda" have been respectively renamed to
wenzelm@44968
  1279
"vec_nth" and "vec_lambda"; theorems mentioning those names have
wenzelm@44968
  1280
changed to match. Definition theorems for overloaded constants now use
wenzelm@44968
  1281
the standard "foo_vec_def" naming scheme. A few other theorems have
wenzelm@44968
  1282
been renamed as follows (INCOMPATIBILITY):
wenzelm@44968
  1283
wenzelm@44968
  1284
  Cart_eq          ~> vec_eq_iff
wenzelm@44968
  1285
  dist_nth_le_cart ~> dist_vec_nth_le
wenzelm@44968
  1286
  tendsto_vector   ~> vec_tendstoI
wenzelm@44968
  1287
  Cauchy_vector    ~> vec_CauchyI
wenzelm@44968
  1288
wenzelm@44968
  1289
* Session Multivariate_Analysis: Several duplicate theorems have been
wenzelm@44968
  1290
removed, and other theorems have been renamed or replaced with more
wenzelm@44968
  1291
general versions. INCOMPATIBILITY.

wenzelm@43731
  1410
* The inner syntax of sort/type/term/prop supports inlined YXML
wenzelm@43731
  1411
representations within quoted string tokens.  By encoding logical
wenzelm@43731
  1412
entities via Term_XML (in ML or Scala) concrete syntax can be
wenzelm@43731
  1413
bypassed, which is particularly useful for producing bits of text

* Inner syntax: identifiers in parse trees of generic categories
wenzelm@42056
  1433
"logic", "aprop", "idt" etc. carry position information (disguised as
wenzelm@42056
  1434
type constraints).  Occasional INCOMPATIBILITY with non-compliant
wenzelm@42057
  1435
translations that choke on unexpected type constraints.  Positions can
wenzelm@42057
  1436
be stripped in ML translations via Syntax.strip_positions /
wenzelm@42057
  1437
Syntax.strip_positions_ast, or via the syntax constant
wenzelm@42057
  1438
"_strip_positions" within parse trees.  As last resort, positions can
wenzelm@42057
  1439
be disabled via the configuration option Syntax.positions, which is
wenzelm@42057
  1440
called "syntax_positions" in Isar attribute syntax.

  1442
* Discontinued special status of various ML structures that contribute
wenzelm@42290

wenzelm@42370
  1453
wenzelm@42403
  1454
* Slightly more special eq_list/eq_set, with shortcut involving
wenzelm@42403
  1455
pointer equality (assumes that eq relation is reflexive).
wenzelm@42403
  1456
wenzelm@42793
  1457
* Classical tactics use proper Proof.context instead of historic types
wenzelm@42793
  1458
claset/clasimpset.  Old-style declarations like addIs, addEs, addDs
wenzelm@42793
  1459
operate directly on Proof.context.  Raw type claset retains its use as
wenzelm@42793
  1460
snapshot of the classical context, which can be recovered via
wenzelm@42793
  1461
(put_claset HOL_cs) etc.  Type clasimpset has been discontinued.
wenzelm@42793
  1462
INCOMPATIBILITY, classical tactics and derived proof methods require

* Scala layer provides JVM method invocation service for static

wenzelm@43752
  1490
  Invoke_Scala.method "java.lang.System.getProperty" "java.home"
wenzelm@43752

wenzelm@44967
  1492
Together with YXML.string_of_body/parse_body and XML.Encode/Decode
wenzelm@44967

  1505
*** General ***
wenzelm@37536
  1506
wenzelm@41573
  1507
* Experimental Prover IDE based on Isabelle/Scala and jEdit (see
wenzelm@41612
  1508
src/Tools/jEdit).  This also serves as IDE for Isabelle/ML, with
wenzelm@41612
  1509
useful tooltips and hyperlinks produced from its static analysis.  The
wenzelm@41612
  1510
bundled component provides an executable Isabelle tool that can be run
wenzelm@41612
  1511
like this:
wenzelm@41612
  1512
wenzelm@41612
  1513
  Isabelle2011/bin/isabelle jedit
wenzelm@41573
  1514
wenzelm@40948
  1515
* Significantly improved Isabelle/Isar implementation manual.
wenzelm@40948
  1516
wenzelm@41594
  1517
* System settings: ISABELLE_HOME_USER now includes ISABELLE_IDENTIFIER
wenzelm@41595
  1518
(and thus refers to something like $HOME/.isabelle/Isabelle2011),
wenzelm@41594
  1519
while the default heap location within that directory lacks that extra
wenzelm@41594
  1520
suffix.  This isolates multiple Isabelle installations from each
wenzelm@41594
  1521
other, avoiding problems with old settings in new versions.
wenzelm@41594
  1522
INCOMPATIBILITY, need to copy/upgrade old user settings manually.
wenzelm@41594
  1523
wenzelm@40947
  1524
* Source files are always encoded as UTF-8, instead of old-fashioned
wenzelm@40947
  1525
ISO-Latin-1.  INCOMPATIBILITY.  Isabelle LaTeX documents might require
wenzelm@40948
  1526
the following package declarations:
wenzelm@40947
  1527
wenzelm@40947
  1528
  \usepackage[utf8]{inputenc}
wenzelm@40947
  1529
  \usepackage{textcomp}
wenzelm@40947
  1530
krauss@41440
  1531
* Explicit treatment of UTF-8 sequences as Isabelle symbols, such that
wenzelm@37536
  1532
a Unicode character is treated as a single symbol, not a sequence of
wenzelm@37536
  1533
non-ASCII bytes as before.  Since Isabelle/ML string literals may
wenzelm@37536
  1534
contain symbols without further backslash escapes, Unicode can now be
wenzelm@37536
  1535
used here as well.  Recall that Symbol.explode in ML provides a
wenzelm@37536
  1536
consistent view on symbols, while raw explode (or String.explode)
wenzelm@37536
  1537
merely give a byte-oriented representation.
wenzelm@37536
  1538
wenzelm@41594
  1539
* Theory loader: source files are primarily located via the master
wenzelm@41594
  1540
directory of each theory node (where the .thy file itself resides).
wenzelm@41594
  1541
The global load path is still partially available as legacy feature.
wenzelm@41594
  1542
Minor INCOMPATIBILITY due to subtle change in file lookup: use
wenzelm@41594
  1543
explicit paths, relatively to the theory.
wenzelm@38135
  1544
wenzelm@37939
  1545
* Special treatment of ML file names has been discontinued.
wenzelm@37939
  1546
Historically, optional extensions .ML or .sml were added on demand --
wenzelm@37939
  1547
at the cost of clarity of file dependencies.  Recall that Isabelle/ML
wenzelm@37939
  1548
files exclusively use the .ML extension.  Minor INCOMPATIBILTY.
wenzelm@37939
  1549
wenzelm@38980
  1550
* Various options that affect pretty printing etc. are now properly
wenzelm@38767
  1551
handled within the context via configuration options, instead of
wenzelm@40879
  1552
unsynchronized references or print modes.  There are both ML Config.T
wenzelm@40879
  1553
entities and Isar declaration attributes to access these.

  1583
"no_abbrevs" with inverted meaning.
wenzelm@38767

wenzelm@41594

that would be activated if the specified expression was interpreted in
wenzelm@41594
  1624
the current context.  Variant "print_dependencies!" assumes a context

* Coercive subtyping: functions can be declared as coercions and type
wenzelm@41594
  1653
inference will add them as necessary upon input of a term.  Theory
wenzelm@41594
  1654
Complex_Main declares real :: nat => real and real :: int => real as
wenzelm@41594
  1655
coercions. A coercion function f is declared like this:
wenzelm@40939
  1656
wenzelm@40939
  1657
  declare [[coercion f]]
nipkow@40866
  1658
wenzelm@41571
  1659
To lift coercions through type constructors (e.g. from nat => real to
nipkow@40866
  1660
nat list => real list), map functions can be declared, e.g.
nipkow@40866
  1661
wenzelm@40939
  1662
  declare [[coercion_map map]]
wenzelm@40939
  1663
wenzelm@40939
  1664
Currently coercion inference is activated only in theories including
wenzelm@40939
  1665
real numbers, i.e. descendants of Complex_Main.  This is controlled by
wenzelm@41020
  1666
the configuration option "coercion_enabled", e.g. it can be enabled in
wenzelm@40939
  1667
other theories like this:
wenzelm@40939

wenzelm@41594
  1684
* Inductive package: now offers command 'inductive_simps' to
wenzelm@41594
  1685
automatically derive instantiated and simplified equations for
wenzelm@41594
  1686
inductive predicates, similar to 'inductive_cases'.
wenzelm@41594
  1687
wenzelm@41571

wenzelm@41571
  1689
functorial structure of types.

  1690
haftmann@39644

* Code generator for records: more idiomatic representation of record
wenzelm@40948
  1711
types.  Warning: records are not covered by ancient SML code
wenzelm@40948
  1712
generation any longer.  INCOMPATIBILITY.  In cases of need, a suitable
wenzelm@40948

  1717
  rep_datatype foo_ext ...
haftmann@38535
  1718
wenzelm@41594
  1719
* Records: logical foundation type for records does not carry a
wenzelm@41594
  1720
'_type' suffix any longer (obsolete due to authentic syntax).

* Quickcheck now by default uses exhaustive testing instead of random
wenzelm@41571
  1724
testing.  Random testing can be invoked by "quickcheck [random]",
wenzelm@41571
  1725
exhaustive testing by "quickcheck [exhaustive]".
haftmann@41398
  1726
haftmann@41398
  1727
* Quickcheck instantiates polymorphic types with small finite
haftmann@41398
  1728
datatypes by default. This enables a simple execution mechanism to
haftmann@41398
  1729
handle quantifiers and function equality over the finite datatypes.
haftmann@41398
  1730
wenzelm@41571
  1731
* Quickcheck random generator has been renamed from "code" to
wenzelm@41571
  1732
"random".  INCOMPATIBILITY.
haftmann@41398
  1733
haftmann@41398
  1734
* Quickcheck now has a configurable time limit which is set to 30
haftmann@41398
  1735
seconds by default. This can be changed by adding [timeout = n] to the
haftmann@41398
  1736
quickcheck command. The time limit for Auto Quickcheck is still set
haftmann@41398
  1737
independently.
haftmann@38461

blanchet@40059
  1742
* Sledgehammer:
wenzelm@41571
  1743
  - Added "smt" and "remote_smt" provers based on the "smt" proof
wenzelm@41571
  1744
    method. See the Sledgehammer manual for details ("isabelle doc
wenzelm@41571
  1745
    sledgehammer").

  1754
    sledgehammer [timeout = 77 s] ~> sledgehammer [timeout = 77]
blanchet@40341

blanchet@40341
  1756
    INCOMPATIBILITY.
blanchet@40341
  1757
blanchet@40341
  1758
* Nitpick:
blanchet@40341
  1759
  - Renamed options:
blanchet@40341
  1760
    nitpick [timeout = 77 s] ~> nitpick [timeout = 77]
blanchet@40341
  1761
    nitpick [tac_timeout = 777 ms] ~> nitpick [tac_timeout = 0.777]
blanchet@40059
  1762
    INCOMPATIBILITY.
blanchet@40725
  1763
  - Added support for partial quotient types.
blanchet@40725
  1764
  - Added local versions of the "Nitpick.register_xxx" functions.
blanchet@40725
  1765
  - Added "whack" option.
blanchet@40725
  1766
  - Allow registration of quotient types as codatatypes.
blanchet@40725
  1767
  - Improved "merge_type_vars" option to merge more types.
blanchet@40725
  1768
  - Removed unsound "fast_descrs" option.
blanchet@40725
  1769
  - Added custom symmetry breaking for datatypes, making it possible to reach
blanchet@40725
  1770
    higher cardinalities.
blanchet@40725
  1771
  - Prevent the expansion of too large definitions.
blanchet@39957
  1772
wenzelm@41571
  1773
* Proof methods "metis" and "meson" now have configuration options
wenzelm@41571
  1774
"meson_trace", "metis_trace", and "metis_verbose" that can be enabled
wenzelm@41571
  1775
to diagnose these tools. E.g.
wenzelm@41571
  1776
wenzelm@41571
  1777
    using [[metis_trace = true]]
wenzelm@41571
  1778
haftmann@41398
  1779
* Auto Solve: Renamed "Auto Solve Direct".  The tool is now available
haftmann@41398
  1780
manually as command 'solve_direct'.
haftmann@41398
  1781
boehmes@41601
  1782
* The default SMT solver Z3 must be enabled explicitly (due to
boehmes@41601
  1783
licensing issues) by setting the environment variable
wenzelm@41603
  1784
Z3_NON_COMMERCIAL in etc/settings of the component, for example.  For
wenzelm@41603
  1785
commercial applications, the SMT solver CVC3 is provided as fall-back;
wenzelm@41603
  1786
changing the SMT solver is done via the configuration option
wenzelm@41603
  1787
"smt_solver".
boehmes@41432
  1788
boehmes@41432
  1789
* Remote SMT solvers need to be referred to by the "remote_" prefix,
wenzelm@41571
  1790
i.e. "remote_cvc3" and "remote_z3".
wenzelm@41571
  1791
wenzelm@41571
  1792
* Added basic SMT support for datatypes, records, and typedefs using
wenzelm@41571
  1793
the oracle mode (no proofs).  Direct support of pairs has been dropped
wenzelm@41571
  1794
in exchange (pass theorems fst_conv snd_conv pair_collapse to the SMT
wenzelm@41571
  1795
support for a similar behavior).  Minor INCOMPATIBILITY.
boehmes@41432
  1796
boehmes@40162
  1797
* Changed SMT configuration options:
boehmes@40162
  1798
  - Renamed:

boehmes@40580
  1815
wenzelm@41594
  1816
* Simplification procedure "list_to_set_comprehension" rewrites list
wenzelm@41594
  1817
comprehensions applied to List.set to set comprehensions.  Occasional
wenzelm@41594
  1818
INCOMPATIBILITY, may be deactivated like this:
wenzelm@41594
  1819
wenzelm@41594
  1820
  declare [[simproc del: list_to_set_comprehension]]
wenzelm@41594
  1821
wenzelm@41573
  1822
* Removed old version of primrec package.  INCOMPATIBILITY.
haftmann@41398
  1823
haftmann@41398
  1824
* Removed simplifier congruence rule of "prod_case", as has for long
haftmann@41398
  1825
been the case with "split".  INCOMPATIBILITY.
haftmann@41398
  1826

* String.literal is a type, but not a datatype.  INCOMPATIBILITY.
haftmann@41398
  1828
krauss@40388
  1829
* Removed [split_format ... and ... and ...] version of
krauss@40388
  1830
[split_format].  Potential INCOMPATIBILITY.
krauss@40388
  1831
wenzelm@41571
  1832
* Predicate "sorted" now defined inductively, with nice induction
wenzelm@41571
  1833
rules.  INCOMPATIBILITY: former sorted.simps now named sorted_simps.
haftmann@41398
  1834
haftmann@41398
  1835
* Constant "contents" renamed to "the_elem", to free the generic name
haftmann@41398

wenzelm@41571
  2029
* The old type class "rep" has been superseded by class "domain".
huffman@40621
  2030
Accordingly, users of the definitional package must remove any
wenzelm@41571
  2031
"default_sort rep" declarations.  INCOMPATIBILITY.
huffman@40621
  2032
huffman@41401
  2033
* The domain package (definitional mode) now supports unpointed
huffman@41401
  2034
predomain argument types, as long as they are marked 'lazy'. (Strict
wenzelm@41571
  2035
arguments must be in class "domain".) For example, the following
huffman@41401
  2036
domain definition now works:
huffman@41401
  2037
huffman@41401
  2038
  domain natlist = nil | cons (lazy "nat discr") (lazy "natlist")
huffman@41401

huffman@41401
  2040
* Theory HOLCF/Library/HOL_Cpo provides cpo and predomain class

  2041
instances for types from main HOL: bool, nat, int, char, 'a + 'b,
wenzelm@41571
  2042
'a option, and 'a list.  Additionally, it configures fixrec and the
wenzelm@41571
  2043
domain package to work with these types.  For example:
huffman@41401
  2044
huffman@41401
  2045
  fixrec isInl :: "('a + 'b) u -> tr"
huffman@41401

huffman@41401
  2049
wenzelm@41571
  2050
* The "(permissive)" option of fixrec has been replaced with a
wenzelm@41571

wenzelm@41571
  2053
wenzelm@41571
  2054

wenzelm@41571
  2056
wenzelm@41571
  2057
* Former type "alg_defl" has been renamed to "defl".  HOLCF no longer
huffman@41287

discontinued -- use plain := instead.  This should be *rare* anyway,
wenzelm@38980

interrupts -- intermediate handling (for cleanup etc.) needs to be
wenzelm@39239
  2257
followed by re-raising of the original exception.  Another common
wenzelm@39239

*** General ***

wenzelm@35436
  2268
* Authentic syntax for *all* logical entities (type classes, type
wenzelm@35436
  2269
constructors, term constants): provides simple and robust
wenzelm@35436
  2270
correspondence between formal entities and concrete syntax.  Within
wenzelm@35436
  2271
the parse tree / AST representations, "constants" are decorated by
wenzelm@35436
  2272
their category (class, type, const) and spelled out explicitly with
wenzelm@35436
  2273
their full internal name.
wenzelm@35436
  2274
wenzelm@35436
  2275
Substantial INCOMPATIBILITY concerning low-level syntax declarations
wenzelm@35436
  2276
and translations (translation rules and translation functions in ML).
wenzelm@35436
  2277
Some hints on upgrading:
wenzelm@35260
  2278
wenzelm@35260
  2279
  - Many existing uses of 'syntax' and 'translations' can be replaced
wenzelm@35436
  2280
    by more modern 'type_notation', 'notation' and 'abbreviation',
wenzelm@35436
  2281
    which are independent of this issue.
wenzelm@35260
  2282
wenzelm@35260
  2283
  - 'translations' require markup within the AST; the term syntax
wenzelm@35260
  2284
    provides the following special forms:
wenzelm@35260
  2285
wenzelm@35260
  2286
      CONST c   -- produces syntax version of constant c from context
wenzelm@35261
  2287
      XCONST c  -- literally c, checked as constant from context
wenzelm@35261
  2288
      c         -- literally c, if declared by 'syntax'
wenzelm@35261
  2289
wenzelm@35261
  2290
    Plain identifiers are treated as AST variables -- occasionally the
wenzelm@35261
  2291
    system indicates accidental variables via the error "rhs contains
wenzelm@35261
  2292
    extra variables".
wenzelm@35260
  2293
wenzelm@35436
  2294
    Type classes and type constructors are marked according to their
wenzelm@35436
  2295
    concrete syntax.  Some old translations rules need to be written
wenzelm@35436
  2296
    for the "type" category, using type constructor application
wenzelm@35436
  2297
    instead of pseudo-term application of the default category
wenzelm@35436
  2298
    "logic".
wenzelm@35436
  2299
wenzelm@35260
  2300
  - 'parse_translation' etc. in ML may use the following
wenzelm@35260
  2301
    antiquotations:
wenzelm@35260
  2302
wenzelm@35436
  2303
      @{class_syntax c}   -- type class c within parse tree / AST
wenzelm@35436
  2304
      @{term_syntax c}    -- type constructor c within parse tree / AST
wenzelm@35260
  2305
      @{const_syntax c}   -- ML version of "CONST c" above
wenzelm@35260
  2306
      @{syntax_const c}   -- literally c (checked wrt. 'syntax' declarations)
wenzelm@35260
  2307
wenzelm@35436
  2308
  - Literal types within 'typed_print_translations', i.e. those *not*
wenzelm@35436
  2309
    represented as pseudo-terms are represented verbatim.  Use @{class
wenzelm@35436
  2310
    c} or @{type_name c} here instead of the above syntax
wenzelm@35436
  2311
    antiquotations.
wenzelm@35436
  2312
wenzelm@35260
  2313
Note that old non-authentic syntax was based on unqualified base
wenzelm@35436
  2314
names, so all of the above "constant" names would coincide.  Recall
wenzelm@35436
  2315
that 'print_syntax' and ML_command "set Syntax.trace_ast" help to
wenzelm@35436
  2316
diagnose syntax problems.
wenzelm@35260
  2317
wenzelm@35351
  2318
* Type constructors admit general mixfix syntax, not just infix.
wenzelm@35351
  2319
wenzelm@36508
  2320
* Concrete syntax may be attached to local entities without a proof
wenzelm@36508
  2321
body, too.  This works via regular mixfix annotations for 'fix',
wenzelm@36508
  2322
'def', 'obtain' etc. or via the explicit 'write' command, which is
wenzelm@36508
  2323
similar to the 'notation' command in theory specifications.
wenzelm@36508
  2324
wenzelm@37351
  2325
* Discontinued unnamed infix syntax (legacy feature for many years) --
wenzelm@37351
  2326
need to specify constant name and syntax separately.  Internal ML
wenzelm@37351
  2327
datatype constructors have been renamed from InfixName to Infix etc.
wenzelm@37351
  2328
Minor INCOMPATIBILITY.
wenzelm@37351
  2329
wenzelm@37351
  2330
* Schematic theorem statements need to be explicitly markup as such,
wenzelm@37351
  2331
via commands 'schematic_lemma', 'schematic_theorem',
wenzelm@37351
  2332
'schematic_corollary'.  Thus the relevance of the proof is made
wenzelm@37351
  2333
syntactically clear, which impacts performance in a parallel or
wenzelm@37351
  2334
asynchronous interactive environment.  Minor INCOMPATIBILITY.
wenzelm@37351
  2335
wenzelm@35613
  2336
* Use of cumulative prems via "!" in some proof methods has been
wenzelm@37351
  2337
discontinued (old legacy feature).
wenzelm@35613
  2338
boehmes@35979
  2339
* References 'trace_simp' and 'debug_simp' have been replaced by
wenzelm@36857
  2340
configuration options stored in the context. Enabling tracing (the
wenzelm@36857
  2341
case of debugging is similar) in proofs works via
wenzelm@36857
  2342
wenzelm@36857
  2343
  using [[trace_simp = true]]
wenzelm@36857
  2344
wenzelm@36857
  2345
Tracing is then active for all invocations of the simplifier in
wenzelm@36857
  2346
subsequent goal refinement steps. Tracing may also still be enabled or
wenzelm@40780
  2347
disabled via the ProofGeneral settings menu.
boehmes@35979
  2348
wenzelm@36177
  2349
* Separate commands 'hide_class', 'hide_type', 'hide_const',
wenzelm@36177
  2350
'hide_fact' replace the former 'hide' KIND command.  Minor
wenzelm@36177
  2351
INCOMPATIBILITY.
wenzelm@36177
  2352
wenzelm@37298
  2353
* Improved parallelism of proof term normalization: usedir -p2 -q0 is
wenzelm@37298
  2354
more efficient than combinations with -q1 or -q2.

*** Pure ***
haftmann@34170
  2358
wenzelm@37351
  2359
* Proofterms record type-class reasoning explicitly, using the
wenzelm@37351
  2360
"unconstrain" operation internally.  This eliminates all sort
wenzelm@37351
  2361
constraints from a theorem and proof, introducing explicit
wenzelm@37351
  2362
OFCLASS-premises.  On the proof term level, this operation is
wenzelm@37351
  2363
automatically applied at theorem boundaries, such that closed proofs
wenzelm@37351
  2364
are always free of sort constraints.  INCOMPATIBILITY for tools that
wenzelm@37351
  2365
inspect proof terms.
haftmann@36147
  2366
wenzelm@35765
  2367
* Local theory specifications may depend on extra type variables that
wenzelm@35765
  2368
are not present in the result type -- arguments TYPE('a) :: 'a itself
wenzelm@35765
  2369
are added internally.  For example:
wenzelm@35765
  2370
wenzelm@35765

wenzelm@37351
  2381
* Command 'code_reflect' allows to incorporate generated ML code into

wenzelm@36857
  2390
wenzelm@37351
  2391
* Methods "unfold_locales" and "intro_locales" ignore non-locale
wenzelm@37351

  2396
experiment with Isar, without producing any persistent result.
wenzelm@36356
  2397
wenzelm@35413
  2398
* Commands 'type_notation' and 'no_type_notation' declare type syntax
wenzelm@35413

within a local theory context, with explicit checking of the
wenzelm@35413
  2400
constructors involved (in contrast to the raw 'syntax' versions).
wenzelm@35413
  2401
wenzelm@36178
  2402
* Commands 'types' and 'typedecl' now work within a local theory
wenzelm@36178

wenzelm@36178
  2404
assumptions, which is not possible in Isabelle/Pure.
wenzelm@35681
  2405
wenzelm@36857

* Command 'typedef' now works within a local theory context -- without
wenzelm@37351
  2413
introducing dependencies on parameters or assumptions, which is not
wenzelm@37351
  2414
possible in Isabelle/Pure/HOL.  Note that the logical environment may
wenzelm@37351
  2415
contain multiple interpretations of local typedefs (with different
wenzelm@37351

non-emptiness proofs), even in a global theory context.
wenzelm@37351
  2417
wenzelm@37351
  2418
* New package for quotient types.  Commands 'quotient_type' and
wenzelm@37351
  2419
'quotient_definition' may be used for defining types and constants by
wenzelm@37351
  2420
quotient constructions.  An example is the type of integers created by
wenzelm@37351
  2421
quotienting pairs of natural numbers:
wenzelm@37380
  2422
wenzelm@37351
  2423
  fun
wenzelm@37380
  2424
    intrel :: "(nat * nat) => (nat * nat) => bool"

    "intrel (x, y) (u, v) = (x + v = u + y)"
wenzelm@37351
  2427
wenzelm@37380

wenzelm@37351
  2434
The method "lifting" can be used to lift of theorems from the
wenzelm@37351
  2435
underlying "raw" type to the quotient type.  The example
wenzelm@37351
  2436
src/HOL/Quotient_Examples/FSet.thy includes such a quotient
wenzelm@37351
  2437
construction and provides a reasoning infrastructure for finite sets.
wenzelm@37351
  2438
wenzelm@37351
  2439
* Renamed Library/Quotient.thy to Library/Quotient_Type.thy to avoid
wenzelm@37351
  2440
clash with new theory Quotient in Main HOL.
wenzelm@37351
  2441
wenzelm@37351
  2442

* Theory "Complete_Lattice": lemmas top_def and bot_def have been
wenzelm@44973
  2619
replaced by the more convenient lemmas Inf_empty and Sup_empty.
wenzelm@44973
  2620
Dropped lemmas Inf_insert_simp and Sup_insert_simp, which are subsumed
wenzelm@44973
  2621
by Inf_insert and Sup_insert.  Lemmas Inf_UNIV and Sup_UNIV replace
wenzelm@44973
  2622
former Inf_Univ and Sup_Univ.  Lemmas inf_top_right and sup_bot_right
wenzelm@44973

  2626
multiset order:
wenzelm@37351
  2627
wenzelm@36857
  2628
  - pointwise ordering is instance of class order with standard syntax
wenzelm@36857
  2629
    <= and <;
wenzelm@36857
  2630
  - multiset ordering has syntax <=# and <#; partial order properties
wenzelm@36857
  2631
    are provided by means of interpretation with prefix
wenzelm@36857
  2632
    multiset_order;
wenzelm@36857
  2633
  - less duplication, less historical organization of sections,
wenzelm@36857
  2634
    conversion from associations lists to multisets, rudimentary code
wenzelm@36857
  2635
    generation;
wenzelm@36857
