New in Isabelle2012 (May 2012)

------------------------------

wenzelm@45593
     7
*** 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@47427
    53
* Rule composition via attribute "OF" (or ML functions OF/MRS) is more
wenzelm@47427
    54
tolerant against multiple unifiers, as long as the final result is
wenzelm@47427
    55
unique.  (As before, rules are composed in canonical right-to-left
wenzelm@47427
    56
order to accommodate newly introduced premises.)
wenzelm@47427
    57
wenzelm@46976
    58
* Command 'definition' no longer exports the foundational "raw_def"
wenzelm@46976
    59
into the user context.  Minor INCOMPATIBILITY, may use the regular
wenzelm@46976
    60
"def" result with attribute "abs_def" to imitate the old version.
wenzelm@46976
    61
wenzelm@46903
    62
* Attribute "abs_def" turns an equation of the form "f x y == t" into
wenzelm@46903
    63
"f == %x y. t", which ensures that "simp" or "unfold" steps always
wenzelm@46903
    64
expand it.  This also works for object-logic equality.  (Formerly
wenzelm@46903
    65
undocumented feature.)
wenzelm@46903
    66
wenzelm@46493
    67
* Discontinued old "prems" fact, which used to refer to the accidental
wenzelm@47464
    68
collection of foundational premises in the context (already marked as
wenzelm@47464
    69
legacy since Isabelle2011).
wenzelm@46493
    70
wenzelm@45134
    71
* Obsolete command 'types' has been discontinued.  Use 'type_synonym'
wenzelm@45134
    72
instead.  INCOMPATIBILITY.
wenzelm@45134
    73
wenzelm@47464
    74
* Old code generator for SML and its commands 'code_module',
wenzelm@45383
    75
'code_library', 'consts_code', 'types_code' have been discontinued.
haftmann@46028
    76
Use commands of the generic code generator instead.  INCOMPATIBILITY.
wenzelm@45383
    77
wenzelm@47464
    78
* Redundant attribute "code_inline" has been discontinued. Use
wenzelm@47464
    79
"code_unfold" instead.  INCOMPATIBILITY.
wenzelm@47464
    80
wenzelm@47464
    81
* Dropped attribute "code_unfold_post" in favor of the its dual
wenzelm@47464
    82
"code_abbrev", which yields a common pattern in definitions like
haftmann@46028
    83
haftmann@46028
    84
  definition [code_abbrev]: "f = t"
haftmann@46028
    85
haftmann@46028
    86
INCOMPATIBILITY.
wenzelm@45383
    87
wenzelm@45427
    88
* Sort constraints are now propagated in simultaneous statements, just
wenzelm@45427
    89
like type constraints.  INCOMPATIBILITY in rare situations, where
wenzelm@45427
    90
distinct sorts used to be assigned accidentally.  For example:
wenzelm@45427
    91
wenzelm@45427
    92
  lemma "P (x::'a::foo)" and "Q (y::'a::bar)"  -- "now illegal"
wenzelm@45427
    93
wenzelm@45427
    94
  lemma "P (x::'a)" and "Q (y::'a::bar)"
wenzelm@47462
    95
    -- "now uniform 'a::bar instead of default sort for first occurrence (!)"
wenzelm@45427
    96
wenzelm@45427
    97
huffman@45122
    98
*** HOL ***
huffman@45122
    99
wenzelm@47464
   100
* New tutorial Programming and Proving in Isabelle/HOL ("prog-prove").
wenzelm@47464
   101
wenzelm@47464
   102
* Discontinued old Tutorial on Isar ("isar-overview");
wenzelm@47464
   103
wenzelm@47464
   104
* Type 'a set is now a proper type constructor (just as before
wenzelm@47464
   105
Isabelle2008).  Definitions mem_def and Collect_def have disappeared.
wenzelm@47464
   106
Non-trivial INCOMPATIBILITY.  For developments keeping predicates and
wenzelm@47464
   107
sets separate, it is often sufficient to rephrase sets S accidentally
wenzelm@47464
   108
used as predicates by "%x. x : S" and predicates P accidentally used
wenzelm@47464
   109
as sets by "{x. P x}".  Corresponding proofs in a first step should be
wenzelm@47464
   110
pruned from any tinkering with former theorems mem_def and Collect_def
wenzelm@47464
   111
as far as possible.
wenzelm@47464
   112
wenzelm@47464
   113
For developments which deliberately mixed predicates and sets, a
wenzelm@47464
   114
planning step is necessary to determine what should become a predicate
wenzelm@47464
   115
and what a set.  It can be helpful to carry out that step in
wenzelm@47464
   116
Isabelle2011-1 before jumping right into the current release.
wenzelm@47464
   117
wenzelm@47464
   118
* The representation of numerals has changed.  Datatype "num"
wenzelm@47464
   119
represents strictly positive binary numerals, along with functions
wenzelm@47464
   120
"numeral :: num => 'a" and "neg_numeral :: num => 'a" to represent
wenzelm@47464
   121
positive and negated numeric literals, respectively. (See definitions
wenzelm@47464
   122
in ~~/src/HOL/Num.thy.) Potential INCOMPATIBILITY, some user theories
wenzelm@47464
   123
may require adaptations as follows:
huffman@47108
   124
huffman@47108
   125
  - Theorems with number_ring or number_semiring constraints: These
huffman@47108
   126
    classes are gone; use comm_ring_1 or comm_semiring_1 instead.
huffman@47108
   127
huffman@47108
   128
  - Theories defining numeric types: Remove number, number_semiring,
huffman@47108
   129
    and number_ring instances. Defer all theorems about numerals until
huffman@47108
   130
    after classes one and semigroup_add have been instantiated.
huffman@47108
   131
huffman@47108
   132
  - Numeral-only simp rules: Replace each rule having a "number_of v"
huffman@47108
   133
    pattern with two copies, one for numeral and one for neg_numeral.
huffman@47108
   134
huffman@47108
   135
  - Theorems about subclasses of semiring_1 or ring_1: These classes
huffman@47108
   136
    automatically support numerals now, so more simp rules and
huffman@47108
   137
    simprocs may now apply within the proof.
huffman@47108
   138
huffman@47108
   139
  - Definitions and theorems using old constructors Pls/Min/Bit0/Bit1:
huffman@47108
   140
    Redefine using other integer operations.
huffman@47108
   141
haftmann@46834
   142
* Code generation by default implements sets as container type rather
haftmann@46834
   143
than predicates.  INCOMPATIBILITY.
haftmann@46834
   144
krauss@47265
   145
* New proof import from HOL Light: Faster, simpler, and more scalable.
krauss@47265
   146
Requires a proof bundle, which is available as an external component.
wenzelm@47464
   147
Discontinued old (and mostly dead) Importer for HOL4 and HOL Light.
krauss@47265
   148
INCOMPATIBILITY.
krauss@47264
   149
nipkow@46373
   150
* New type synonym 'a rel = ('a * 'a) set
nipkow@46373
   151
huffman@47142
   152
* Theory Divides: Discontinued redundant theorems about div and mod.
huffman@47142
   153
INCOMPATIBILITY, use the corresponding generic theorems instead.
huffman@47142
   154
huffman@47142
   155
  DIVISION_BY_ZERO ~> div_by_0, mod_by_0

  zdiv_zminus_zminus ~> div_minus_minus
huffman@47159
   164
  zmod_zminus_zminus ~> mod_minus_minus
huffman@47159
   165
  zdiv_zminus2 ~> div_minus_right
huffman@47159
   166
  zmod_zminus2 ~> mod_minus_right
huffman@47160
   167
  zdiv_minus1_right ~> div_minus1_right
huffman@47160
   168
  zmod_minus1_right ~> mod_minus1_right
huffman@47162
   169
  zdvd_mult_div_cancel ~> dvd_mult_div_cancel
huffman@47163
   170
  zmod_zmult1_eq ~> mod_mult_right_eq
huffman@47164
   171
  zpower_zmod ~> power_mod
huffman@47167

huffman@47159
   174
  mod_mult_distrib ~> mult_mod_left
huffman@47159
   175
  mod_mult_distrib2 ~> mult_mod_right
huffman@47142
   176
huffman@47217
   177
* Removed redundant theorems nat_mult_2 and nat_mult_2_right; use
huffman@47217
   178
generic mult_2 and mult_2_right instead. INCOMPATIBILITY.
huffman@47217
   179
haftmann@46752
   180
* More default pred/set conversions on a couple of relation operations
wenzelm@47464
   181
and predicates.  Added powers of predicate relations.  Consolidation
wenzelm@47464
   182
of some relation theorems:
haftmann@46752
   183
haftmann@46752
   184
  converse_def ~> converse_unfold
haftmann@46752
   185
  rel_comp_def ~> rel_comp_unfold
haftmann@46752
   186
  symp_def ~> (dropped, use symp_def and sym_def instead)
haftmann@46752
   187
  transp_def ~> transp_trans
haftmann@46752
   188
  Domain_def ~> Domain_unfold
haftmann@46752
   189
  Range_def ~> Domain_converse [symmetric]
haftmann@46752
   190
haftmann@46981
   191
Generalized theorems INF_INT_eq, INF_INT_eq2, SUP_UN_eq, SUP_UN_eq2.
haftmann@46981
   192
wenzelm@47464
   193
See theory "Relation" for examples for making use of pred/set
wenzelm@47464
   194
conversions by means of attributes "to_set" and "to_pred".
haftmann@47086
   195
haftmann@46752
   196
INCOMPATIBILITY.
haftmann@46752
   197
wenzelm@46160
   198
* Consolidated various theorem names relating to Finite_Set.fold
wenzelm@46160
   199
combinator:
wenzelm@46160
   200
haftmann@46145
   201
  inf_INFI_fold_inf ~> inf_INF_fold_inf
haftmann@46145
   202
  sup_SUPR_fold_sup ~> sup_SUP_fold_sup
haftmann@46145
   203
  INFI_fold_inf ~> INF_fold_inf
haftmann@46145
   204
  SUPR_fold_sup ~> SUP_fold_sup
haftmann@46145
   205
  union_set ~> union_set_fold
haftmann@46145
   206
  minus_set ~> minus_set_fold
haftmann@46752
   207
haftmann@46145
   208
INCOMPATIBILITY.
haftmann@46145
   209
haftmann@46132
   210
* Consolidated theorem names concerning fold combinators:
wenzelm@46160
   211
haftmann@46132
   212
  INFI_set_fold ~> INF_set_fold
haftmann@46132
   213
  SUPR_set_fold ~> SUP_set_fold
haftmann@46132
   214
  INF_code ~> INF_set_foldr
haftmann@46132
   215
  SUP_code ~> SUP_set_foldr
haftmann@47397
   216
  foldr.simps ~> foldr.simps (in point-free formulation)
haftmann@47397
   217
  foldr_fold_rev ~> foldr_conv_fold
haftmann@47397
   218
  foldl_fold ~> foldl_conv_fold
haftmann@47397
   219
  foldr_foldr ~> foldr_conv_foldl
haftmann@47397
   220
  foldl_foldr ~> foldl_conv_foldr
wenzelm@46160
   221
haftmann@46132
   222
INCOMPATIBILITY.
haftmann@46132
   223
wenzelm@46160
   224
* Dropped rarely useful theorems concerning fold combinators:
wenzelm@46160
   225
foldl_apply, foldl_fun_comm, foldl_rev, fold_weak_invariant,
wenzelm@46160
   226
rev_foldl_cons, fold_set_remdups, fold_set, fold_set1,
wenzelm@46160
   227
concat_conv_foldl, foldl_weak_invariant, foldl_invariant,
wenzelm@46160
   228
foldr_invariant, foldl_absorb0, foldl_foldr1_lemma, foldl_foldr1,
haftmann@47397
   229
listsum_conv_fold, listsum_foldl, sort_foldl_insort, foldl_assoc,
haftmann@47397
   230
foldr_conv_foldl, start_le_sum, elem_le_sum, sum_eq_0_conv.
haftmann@47397
   231
INCOMPATIBILITY.  For the common phrases "%xs. List.foldr plus xs 0"
wenzelm@47464
   232
and "List.foldl plus 0", prefer "List.listsum".  Otherwise it can be
wenzelm@47464
   233
useful to boil down "List.foldr" and "List.foldl" to "List.fold" by
wenzelm@47464
   234
unfolding "foldr_conv_fold" and "foldl_conv_fold".
haftmann@47399
   235
haftmann@47399
   236
* Dropped lemmas minus_set_foldr, union_set_foldr, union_coset_foldr,
haftmann@47399
   237
inter_coset_foldr, Inf_fin_set_foldr, Sup_fin_set_foldr,
haftmann@47399
   238
Min_fin_set_foldr, Max_fin_set_foldr, Inf_set_foldr, Sup_set_foldr,
haftmann@47399
   239
INF_set_foldr, SUP_set_foldr.  INCOMPATIBILITY.  Prefer corresponding
haftmann@47399
   240
lemmas over fold rather than foldr, or make use of lemmas
haftmann@47399
   241
fold_conv_foldr and fold_rev.
haftmann@46132
   242
krauss@46528
   243
* Congruence rules Option.map_cong and Option.bind_cong for recursion
krauss@46528
   244
through option types.
krauss@46528
   245
wenzelm@46125
   246
* Concrete syntax for case expressions includes constraints for source
wenzelm@46125
   247
positions, and thus produces Prover IDE markup for its bindings.
wenzelm@46125
   248
INCOMPATIBILITY for old-style syntax translations that augment the
wenzelm@46125
   249
pattern notation; e.g. see src/HOL/HOLCF/One.thy for translations of
wenzelm@46125
   250
one_case.
wenzelm@46125
   251
wenzelm@46126
   252
* Discontinued configuration option "syntax_positions": atomic terms
wenzelm@46126
   253
in parse trees are always annotated by position constraints.
wenzelm@46126
   254
haftmann@45991
   255
* Finite_Set.fold now qualified.  INCOMPATIBILITY.
haftmann@45991
   256
wenzelm@46160
   257
* Renamed some facts on canonical fold on lists, in order to avoid
wenzelm@46160
   258
problems with interpretation involving corresponding facts on foldl
wenzelm@46160
   259
with the same base names:
haftmann@45988
   260
haftmann@45988
   261
  fold_set_remdups ~> fold_set_fold_remdups
haftmann@45988
   262
  fold_set ~> fold_set_fold
haftmann@45988
   263
  fold1_set ~> fold1_set_fold

wenzelm@45383
   553
* New "case_product" attribute to generate a case rule doing multiple
wenzelm@45383
   554
case distinctions at the same time.  E.g.
wenzelm@45383
   555
wenzelm@45383
   556
  list.exhaust [case_product nat.exhaust]
wenzelm@45383
   557
wenzelm@45383
   558
produces a rule which can be used to perform case distinction on both
wenzelm@45383
   559
a list and a nat.
wenzelm@45383
   560
wenzelm@47464
   561
* Theory Library/Multiset: Improved code generation of multisets.
wenzelm@47464
   562
wenzelm@47464
   563
* New diagnostic command 'find_unused_assms' to find potentially
wenzelm@47464
   564
superfluous assumptions in theorems using Quickcheck.
bulwahn@46591
   565
bulwahn@45759
   566
* Quickcheck:
wenzelm@47464
   567
bulwahn@45759
   568
  - Quickcheck returns variable assignments as counterexamples, which
bulwahn@45759
   569
    allows to reveal the underspecification of functions under test.
bulwahn@45759
   570
    For example, refuting "hd xs = x", it presents the variable
bulwahn@45759
   571
    assignment xs = [] and x = a1 as a counterexample, assuming that
bulwahn@45759
   572
    any property is false whenever "hd []" occurs in it.
wenzelm@47464
   573
bulwahn@45759
   574
    These counterexample are marked as potentially spurious, as
bulwahn@45759
   575
    Quickcheck also returns "xs = []" as a counterexample to the
bulwahn@45759
   576
    obvious theorem "hd xs = hd xs".
wenzelm@47464
   577
bulwahn@45759
   578
    After finding a potentially spurious counterexample, Quickcheck
bulwahn@45759
   579
    continues searching for genuine ones.
wenzelm@47464
   580
bulwahn@45759
   581
    By default, Quickcheck shows potentially spurious and genuine
wenzelm@47464
   582
    counterexamples. The option "genuine_only" sets quickcheck to only
wenzelm@47464
   583
    show genuine counterexamples.
bulwahn@45941
   584
bulwahn@45941
   585
  - The command 'quickcheck_generator' creates random and exhaustive
bulwahn@45941
   586
    value generators for a given type and operations.
wenzelm@47464
   587
bulwahn@45941
   588
    It generates values by using the operations as if they were
wenzelm@47463
   589
    constructors of that type.
bulwahn@46170
   590
bulwahn@46170
   591
  - Support for multisets.
bulwahn@46170
   592
bulwahn@46591
   593
  - Added "use_subtype" options.
wenzelm@47464
   594
bulwahn@47349
   595
  - Added "quickcheck_locale" configuration to specify how to process
bulwahn@47349
   596
    conjectures in a locale context.
bulwahn@47349
   597
blanchet@45398
   598
* Nitpick:
wenzelm@47464
   599
blanchet@45516
   600
  - Fixed infinite loop caused by the 'peephole_optim' option and
blanchet@45516
   601
    affecting 'rat' and 'real'.
blanchet@45516
   602
blanchet@45516
   603
* Sledgehammer:
blanchet@46409
   604
  - Added "lam_trans", "uncurry_aliases", and "minimize" options.
blanchet@45706
   605
  - Renamed "slicing" ("no_slicing") option to "slice" ("dont_slice").
blanchet@46301
   606
  - Renamed "sound" option to "strict".
blanchet@45516
   607
blanchet@45516
   608
* Metis:
blanchet@45516
   609
  - Added possibility to specify lambda translations scheme as a
blanchet@46366
   610
    parenthesized argument (e.g., "by (metis (lifting) ...)").
blanchet@45398
   611
bulwahn@47197
   612
* SMT:
bulwahn@47197
   613
  - renamed "smt_fixed" option to "smt_read_only_certificates".
wenzelm@47463
   614
blanchet@46641
   615
* Command 'try0':
blanchet@46641
   616
  - Renamed from 'try_methods'. INCOMPATIBILITY.
blanchet@46641
   617
noschinl@46888
   618
* New "eventually_elim" method as a generalized variant of the
wenzelm@47464
   619
eventually_elim* rules. Supports structured proofs.
noschinl@46888
   620
wenzelm@47413
   621
* HOL/TPTP: support to parse and import TPTP problems (all languages)
wenzelm@47464

wenzelm@47463
   633
analysis.
wenzelm@47463
   634
wenzelm@47463
   635
* Much greater use of mathematical symbols.
wenzelm@47463
   636
wenzelm@47463

*** ML ***
wenzelm@45128
   641
wenzelm@46948
   642
* Antiquotation @{keyword "name"} produces a parser for outer syntax
wenzelm@46948
   643
from a minor keyword introduced via theory header declaration.
wenzelm@46948
   644
wenzelm@46961
   645
* Antiquotation @{command_spec "name"} produces the
wenzelm@46961
   646
Outer_Syntax.command_spec from a major keyword introduced via theory
wenzelm@46961
   647
header declaration; it can be passed to Outer_Syntax.command etc.
wenzelm@46961
   648
wenzelm@46916
   649
* Local_Theory.define no longer hard-wires default theorem name
wenzelm@46992
   650
"foo_def", but retains the binding as given.  If that is Binding.empty
wenzelm@46992
   651
/ Attrib.empty_binding, the result is not registered as user-level
wenzelm@46992
   652
fact.  The Local_Theory.define_internal variant allows to specify a
wenzelm@46992
   653
non-empty name (used for the foundation in the background theory),
wenzelm@46992
   654
while omitting the fact binding in the user-context.  Potential
wenzelm@46992
   655
INCOMPATIBILITY for derived definitional packages: need to specify
wenzelm@46992
   656
naming policy for primitive definitions more explicitly.
wenzelm@46916
   657
wenzelm@46497
   658
* Renamed Thm.capply to Thm.apply, and Thm.cabs to Thm.lambda in
wenzelm@46497
   659
conformance with similar operations in structure Term and Logic.
wenzelm@46497
   660
wenzelm@45592
   661
* Antiquotation @{attributes [...]} embeds attribute source
wenzelm@45592
   662
representation into the ML text, which is particularly useful with
wenzelm@45592
   663
declarations like Local_Theory.note.
wenzelm@45592
   664
wenzelm@45128
   665
* Structure Proof_Context follows standard naming scheme.  Old

   666
ProofContext has been discontinued.  INCOMPATIBILITY.
wenzelm@45128
   667
wenzelm@45293
   668
* Refined Local_Theory.declaration {syntax, pervasive}, with subtle
wenzelm@45298
   669
change of semantics: update is applied to auxiliary local theory
wenzelm@45293
   670

*** General ***
wenzelm@41703
   702
wenzelm@44760
   703
* Improved Isabelle/jEdit Prover IDE (PIDE), which can be invoked as
wenzelm@44968
   704
"isabelle jedit" or "ISABELLE_HOME/Isabelle" on the command line.
wenzelm@44760
   705
wenzelm@44777
   706
  - Management of multiple theory files directly from the editor
wenzelm@44760
   707
    buffer store -- bypassing the file-system (no requirement to save
wenzelm@44760
   708
    files for checking).
wenzelm@44760
   709
wenzelm@44777
   710
  - Markup of formal entities within the text buffer, with semantic
wenzelm@44760
   711
    highlighting, tooltips and hyperlinks to jump to defining source
wenzelm@44760
   712
    positions.
wenzelm@44760
   713
wenzelm@44777
   714
  - Improved text rendering, with sub/superscripts in the source
wenzelm@44777
   715
    buffer (including support for copy/paste wrt. output panel, HTML
wenzelm@44777
   716
    theory output and other non-Isabelle text boxes).
wenzelm@44777
   717
wenzelm@44777
   718
  - Refined scheduling of proof checking and printing of results,
wenzelm@44760
   719
    based on interactive editor view.  (Note: jEdit folding and
wenzelm@44760
   720
    narrowing allows to restrict buffer perspectives explicitly.)
wenzelm@44760
   721
wenzelm@44777
   722
  - Reduced CPU performance requirements, usable on machines with few
wenzelm@44760
   723
    cores.
wenzelm@44760
   724
wenzelm@44777
   725
  - Reduced memory requirements due to pruning of unused document
wenzelm@44760
   726
    versions (garbage collection).

   729
including some remaining limitations.

wenzelm@44800
   731
* Theory loader: source files are exclusively located via the master
wenzelm@44800
   732
directory of each theory node (where the .thy file itself resides).
wenzelm@44800
   733
The global load path (such as src/HOL/Library) has been discontinued.
wenzelm@44800
   734
Note that the path element ~~ may be used to reference theories in the
wenzelm@44800
   735
Isabelle home folder -- for instance, "~~/src/HOL/Library/FuncSet".
wenzelm@44800
   736
INCOMPATIBILITY.
wenzelm@44800
   737
wenzelm@41955
   738
* Theory loader: source files are identified by content via SHA1
wenzelm@41955
   739
digests.  Discontinued former path/modtime identification and optional
wenzelm@41955
   740
ISABELLE_FILE_IDENT plugin scripts.
wenzelm@41955
   741
wenzelm@41703
   742
* Parallelization of nested Isar proofs is subject to
wenzelm@41703
   743
Goal.parallel_proofs_threshold (default 100).  See also isabelle
wenzelm@41703
   744
usedir option -Q.
wenzelm@41703
   745
wenzelm@42669
   746
* Name space: former unsynchronized references are now proper
wenzelm@42669
   747
configuration options, with more conventional names:
wenzelm@42669
   748
wenzelm@42669
   749
  long_names   ~> names_long
wenzelm@42669
   750
  short_names  ~> names_short
wenzelm@42669
   751
  unique_names ~> names_unique
wenzelm@42669
   752
wenzelm@42669
   753
Minor INCOMPATIBILITY, need to declare options in context like this:
wenzelm@42669
   754
wenzelm@42669
   755
  declare [[names_unique = false]]
wenzelm@42358
   756
wenzelm@42502
   757
* Literal facts `prop` may contain dummy patterns, e.g. `_ = _`.  Note
wenzelm@42502
   758
that the result needs to be unique, which means fact specifications
wenzelm@42502
   759
may have to be refined after enriching a proof context.
wenzelm@42502
   760
wenzelm@44800
   761
* Attribute "case_names" has been refined: the assumptions in each case
wenzelm@44800
   762
can be named now by following the case name with [name1 name2 ...].
wenzelm@44800
   763
wenzelm@44968
   764
* Isabelle/Isar reference manual has been updated and extended:
wenzelm@44968
   765
  - "Synopsis" provides a catalog of main Isar language concepts.
wenzelm@44968
   766
  - Formal references in syntax diagrams, via @{rail} antiquotation.
wenzelm@44968
   767
  - Updated material from classic "ref" manual, notably about

   956
generalized.  Now it is defined on the type class {topological_space,
wenzelm@44967
   957
comm_monoid_add}.  Hence it is useable also for extended real numbers.
wenzelm@42484
   958
huffman@44908
   959
* Theory Complex_Main: The complex exponential function "expi" is now
huffman@44908
   960
a type-constrained abbreviation for "exp :: complex => complex"; thus
huffman@44908
   961
several polymorphic lemmas about "exp" are now applicable to "expi".
huffman@44908
   962
wenzelm@44968
   963
* Code generation:
wenzelm@44968
   964
wenzelm@44968
   965
  - Theory Library/Code_Char_ord provides native ordering of
wenzelm@44968
   966
    characters in the target language.
wenzelm@44968
   967
wenzelm@44968
   968
  - Commands code_module and code_library are legacy, use export_code
wenzelm@44968
   969
    instead.
wenzelm@44968
   970
wenzelm@44968
   971
  - Method "evaluation" is legacy, use method "eval" instead.
wenzelm@44968
   972
wenzelm@44968
   973
  - Legacy evaluator "SML" is deactivated by default.  May be
wenzelm@44968
   974
    reactivated by the following theory command:
wenzelm@44968
   975
wenzelm@44968
   976
      setup {* Value.add_evaluator ("SML", Codegen.eval_term) *}
wenzelm@44968
   977
wenzelm@44968
   978
* Declare ext [intro] by default.  Rare INCOMPATIBILITY.
wenzelm@44968
   979
wenzelm@45088
   980
* New proof method "induction" that gives induction hypotheses the
wenzelm@45088
   981
name "IH", thus distinguishing them from further hypotheses that come
wenzelm@45088
   982
from rule induction.  The latter are still called "hyps".  Method
wenzelm@45088
   983
"induction" is a thin wrapper around "induct" and follows the same
wenzelm@45088
   984
syntax.
wenzelm@45088
   985
wenzelm@44968
   986
* Method "fastsimp" has been renamed to "fastforce", but "fastsimp" is
wenzelm@44968
   987
still available as a legacy feature for some time.
wenzelm@44968
   988
wenzelm@44968
   989
* Nitpick:
wenzelm@44968
   990
  - Added "need" and "total_consts" options.
wenzelm@44968
   991
  - Reintroduced "show_skolems" option by popular demand.
wenzelm@44968
   992
  - Renamed attribute: nitpick_def ~> nitpick_unfold.
wenzelm@44968
   993
    INCOMPATIBILITY.
wenzelm@44968
   994
wenzelm@44968
   995
* Sledgehammer:
wenzelm@44968
   996
  - Use quasi-sound (and efficient) translations by default.
wenzelm@44968
   997
  - Added support for the following provers: E-ToFoF, LEO-II,
wenzelm@44968
   998
    Satallax, SNARK, Waldmeister, and Z3 with TPTP syntax.
wenzelm@44968
   999
  - Automatically preplay and minimize proofs before showing them if
wenzelm@44968
  1000
    this can be done within reasonable time.
wenzelm@44968
  1001
  - sledgehammer available_provers ~> sledgehammer supported_provers.
wenzelm@44968
  1002
    INCOMPATIBILITY.
wenzelm@44968
  1003
  - Added "preplay_timeout", "slicing", "type_enc", "sound",
wenzelm@44968
  1004
    "max_mono_iters", and "max_new_mono_instances" options.
wenzelm@44968
  1005
  - Removed "explicit_apply" and "full_types" options as well as "Full
wenzelm@44968
  1006
    Types" Proof General menu item. INCOMPATIBILITY.
wenzelm@44968
  1007
wenzelm@44968
  1008
* Metis:
wenzelm@44968
  1009
  - Removed "metisF" -- use "metis" instead. INCOMPATIBILITY.
wenzelm@44968
  1010
  - Obsoleted "metisFT" -- use "metis (full_types)" instead.
wenzelm@44968
  1011
    INCOMPATIBILITY.
wenzelm@44968
  1012
wenzelm@44968
  1013
* Command 'try':
wenzelm@44968
  1014
  - Renamed 'try_methods' and added "simp:", "intro:", "dest:", and
wenzelm@44968
  1015
    "elim:" options. INCOMPATIBILITY.
wenzelm@44968
  1016
  - Introduced 'try' that not only runs 'try_methods' but also
wenzelm@44968
  1017
    'solve_direct', 'sledgehammer', 'quickcheck', and 'nitpick'.
wenzelm@44968
  1018
wenzelm@44968
  1019
* Quickcheck:
wenzelm@44968
  1020
  - Added "eval" option to evaluate terms for the found counterexample
wenzelm@44968
  1021
    (currently only supported by the default (exhaustive) tester).
wenzelm@44968
  1022
  - Added post-processing of terms to obtain readable counterexamples
wenzelm@44968
  1023
    (currently only supported by the default (exhaustive) tester).
wenzelm@44968
  1024
  - New counterexample generator quickcheck[narrowing] enables
wenzelm@44968
  1025
    narrowing-based testing.  Requires the Glasgow Haskell compiler
wenzelm@44968
  1026
    with its installation location defined in the Isabelle settings
wenzelm@44968
  1027
    environment as ISABELLE_GHC.
wenzelm@44968
  1028
  - Removed quickcheck tester "SML" based on the SML code generator
wenzelm@44968
  1029
    (formly in HOL/Library).
wenzelm@44968
  1030
wenzelm@44968
  1031
* Function package: discontinued option "tailrec".  INCOMPATIBILITY,
wenzelm@44968
  1032
use 'partial_function' instead.
wenzelm@44968
  1033
wenzelm@44968
  1034
* Theory Library/Extended_Reals replaces now the positive extended
wenzelm@44968
  1035
reals found in probability theory. This file is extended by

  1036
Multivariate_Analysis/Extended_Real_Limits.
wenzelm@44968
  1037
wenzelm@44974
  1038
* Theory Library/Old_Recdef: old 'recdef' package has been moved here,
wenzelm@44974
  1039
from where it must be imported explicitly if it is really required.
wenzelm@44974
  1040
INCOMPATIBILITY.
wenzelm@44968
  1041
wenzelm@44968

wenzelm@44968
  1081
fixes a constant "Basis :: 'a set" consisting of the standard
wenzelm@44968
  1082
orthonormal basis for the type. Users now have the option of
wenzelm@44968

quantifying over this set instead of using the "basis" function, e.g.
wenzelm@44968

"ALL x:Basis. P x" vs "ALL i<DIM('a). P (basis i)".
wenzelm@44968
  1085

  1087
to "('a, 'b) vec" (the syntax "'a ^ 'b" remains unaffected). Constants
wenzelm@44968
  1088
"Cart_nth" and "Cart_lambda" have been respectively renamed to
wenzelm@44968
  1089
"vec_nth" and "vec_lambda"; theorems mentioning those names have
wenzelm@44968
  1090
changed to match. Definition theorems for overloaded constants now use
wenzelm@44968
  1091
the standard "foo_vec_def" naming scheme. A few other theorems have
wenzelm@44968
  1092
been renamed as follows (INCOMPATIBILITY):

wenzelm@43731
  1220
* The inner syntax of sort/type/term/prop supports inlined YXML
wenzelm@43731
  1221
representations within quoted string tokens.  By encoding logical
wenzelm@43731
  1222
entities via Term_XML (in ML or Scala) concrete syntax can be
wenzelm@43731
  1223
bypassed, which is particularly useful for producing bits of text

be stripped in ML translations via Syntax.strip_positions /
wenzelm@42057
  1247
Syntax.strip_positions_ast, or via the syntax constant

"_strip_positions" within parse trees.  As last resort, positions can
wenzelm@42057
  1249
be disabled via the configuration option Syntax.positions, which is

wenzelm@42403
  1266
wenzelm@42793
  1267
* Classical tactics use proper Proof.context instead of historic types
wenzelm@42793
  1268
claset/clasimpset.  Old-style declarations like addIs, addEs, addDs
wenzelm@42793
  1269
operate directly on Proof.context.  Raw type claset retains its use as
wenzelm@42793
  1270
snapshot of the classical context, which can be recovered via
wenzelm@42793
  1271
(put_claset HOL_cs) etc.  Type clasimpset has been discontinued.

*** General ***
wenzelm@37536
  1316
wenzelm@41573
  1317
* Experimental Prover IDE based on Isabelle/Scala and jEdit (see
wenzelm@41612
  1318
src/Tools/jEdit).  This also serves as IDE for Isabelle/ML, with
wenzelm@41612
  1319
useful tooltips and hyperlinks produced from its static analysis.  The
wenzelm@41612
  1320
bundled component provides an executable Isabelle tool that can be run
wenzelm@41612
  1321
like this:
wenzelm@41612
  1322
wenzelm@41612
  1323
  Isabelle2011/bin/isabelle jedit
wenzelm@41573
  1324
wenzelm@40948
  1325
* Significantly improved Isabelle/Isar implementation manual.
wenzelm@40948
  1326
wenzelm@41594
  1327
* System settings: ISABELLE_HOME_USER now includes ISABELLE_IDENTIFIER
wenzelm@41595
  1328
(and thus refers to something like $HOME/.isabelle/Isabelle2011),
wenzelm@41594
  1329
while the default heap location within that directory lacks that extra
wenzelm@41594
  1330
suffix.  This isolates multiple Isabelle installations from each
wenzelm@41594
  1331
other, avoiding problems with old settings in new versions.
wenzelm@41594
  1332
INCOMPATIBILITY, need to copy/upgrade old user settings manually.
wenzelm@41594
  1333
wenzelm@40947
  1334
* Source files are always encoded as UTF-8, instead of old-fashioned
wenzelm@40947
  1335
ISO-Latin-1.  INCOMPATIBILITY.  Isabelle LaTeX documents might require
wenzelm@40948
  1336
the following package declarations:
wenzelm@40947
  1337
wenzelm@40947
  1338
  \usepackage[utf8]{inputenc}
wenzelm@40947
  1339
  \usepackage{textcomp}
wenzelm@40947
  1340
krauss@41440
  1341
* Explicit treatment of UTF-8 sequences as Isabelle symbols, such that
wenzelm@37536
  1342
a Unicode character is treated as a single symbol, not a sequence of
wenzelm@37536
  1343
non-ASCII bytes as before.  Since Isabelle/ML string literals may
wenzelm@37536
  1344
contain symbols without further backslash escapes, Unicode can now be
wenzelm@37536
  1345
used here as well.  Recall that Symbol.explode in ML provides a
wenzelm@37536
  1346
consistent view on symbols, while raw explode (or String.explode)
wenzelm@37536
  1347
merely give a byte-oriented representation.
wenzelm@37536
  1348
wenzelm@41594
  1349
* Theory loader: source files are primarily located via the master
wenzelm@41594
  1350
directory of each theory node (where the .thy file itself resides).
wenzelm@41594
  1351
The global load path is still partially available as legacy feature.
wenzelm@41594
  1352
Minor INCOMPATIBILITY due to subtle change in file lookup: use
wenzelm@41594
  1353
explicit paths, relatively to the theory.
wenzelm@38135
  1354
wenzelm@37939
  1355
* Special treatment of ML file names has been discontinued.
wenzelm@37939
  1356
Historically, optional extensions .ML or .sml were added on demand --
wenzelm@37939
  1357
at the cost of clarity of file dependencies.  Recall that Isabelle/ML
wenzelm@37939
  1358
files exclusively use the .ML extension.  Minor INCOMPATIBILTY.
wenzelm@37939
  1359
wenzelm@38980
  1360
* Various options that affect pretty printing etc. are now properly
wenzelm@38767
  1361
handled within the context via configuration options, instead of
wenzelm@40879
  1362
unsynchronized references or print modes.  There are both ML Config.T
wenzelm@40879
  1363
entities and Isar declaration attributes to access these.

Note that corresponding "..._default" references in ML may only be
wenzelm@38767
  1391
changed globally at the ROOT session setup, but *not* within a theory.
wenzelm@40879
  1392
The option "show_abbrevs" supersedes the former print mode
wenzelm@40879
  1393
"no_abbrevs" with inverted meaning.
wenzelm@38767
  1394
wenzelm@40878
  1395
* More systematic naming of some configuration options.
huffman@41294
  1396
INCOMPATIBILITY.

  1399
  debug_simp  ~>  simp_debug
wenzelm@40878
  1400
wenzelm@40291
  1401
* Support for real valued configuration options, using simplistic
wenzelm@40291
  1402
floating-point notation that coincides with the inner syntax for
wenzelm@40291
  1403
float_token.
wenzelm@40291
  1404
wenzelm@41594
  1405
* Support for real valued preferences (with approximative PGIP type):
wenzelm@41594
  1406
front-ends need to accept "pgint" values in float notation.
wenzelm@41594
  1407
INCOMPATIBILITY.
wenzelm@41573
  1408
wenzelm@41573
  1409
* The IsabelleText font now includes Cyrillic, Hebrew, Arabic from
wenzelm@41573
  1410
DejaVu Sans.
wenzelm@41573
  1411
wenzelm@41594
  1412
* Discontinued support for Poly/ML 5.0 and 5.1 versions.

*** Pure ***
wenzelm@40948
  1416
wenzelm@41249
  1417
* Command 'type_synonym' (with single argument) replaces somewhat
wenzelm@41249
  1418
outdated 'types', which is still available as legacy feature for some
wenzelm@41249
  1419
time.
wenzelm@41249
  1420
wenzelm@41249
  1421
* Command 'nonterminal' (with 'and' separated list of arguments)
wenzelm@41249
  1422
replaces somewhat outdated 'nonterminals'.  INCOMPATIBILITY.
wenzelm@41229
  1423
wenzelm@40965
  1424
* Command 'notepad' replaces former 'example_proof' for
wenzelm@41020
  1425
experimentation in Isar without any result.  INCOMPATIBILITY.
wenzelm@40965
  1426
ballarin@41435
  1427
* Locale interpretation commands 'interpret' and 'sublocale' accept
ballarin@41435
  1428
lists of equations to map definitions in a locale to appropriate
ballarin@41435
  1429
entities in the context of the interpretation.  The 'interpretation'
ballarin@41435
  1430
command already provided this functionality.
ballarin@41435
  1431
wenzelm@41594
  1432
* Diagnostic command 'print_dependencies' prints the locale instances
wenzelm@41594
  1433
that would be activated if the specified expression was interpreted in
wenzelm@41594
  1434
the current context.  Variant "print_dependencies!" assumes a context
wenzelm@41594
  1435
without interpretations.
ballarin@38110
  1436
ballarin@38110
  1437
* Diagnostic command 'print_interps' prints interpretations in proofs
ballarin@38110
  1438
in addition to interpretations in theories.
ballarin@38110
  1439
wenzelm@38708
  1440
* Discontinued obsolete 'global' and 'local' commands to manipulate
wenzelm@38708
  1441
the theory name space.  Rare INCOMPATIBILITY.  The ML functions
wenzelm@38708
  1442
Sign.root_path and Sign.local_path may be applied directly where this
wenzelm@38708
  1443
feature is still required for historical reasons.
wenzelm@38708
  1444
wenzelm@40948
  1445
* Discontinued obsolete 'constdefs' command.  INCOMPATIBILITY, use
haftmann@39215
  1446
'definition' instead.
haftmann@39215
  1447
wenzelm@41574
  1448
* The "prems" fact, which refers to the accidental collection of
wenzelm@41574
  1449
foundational premises in the context, is now explicitly marked as
wenzelm@41594
  1450
legacy feature and will be discontinued soon.  Consider using "assms"
wenzelm@41594
  1451
of the head statement or reference facts by explicit names.
wenzelm@41574
  1452
wenzelm@40801
  1453
* Document antiquotations @{class} and @{type} print classes and type
wenzelm@40801
  1454
constructors.
wenzelm@40801
  1455
wenzelm@40801
  1456
* Document antiquotation @{file} checks file/directory entries within
wenzelm@40801
  1457
the local file system.

haftmann@37387
  1461
wenzelm@41594
  1462
* Coercive subtyping: functions can be declared as coercions and type
wenzelm@41594
  1463
inference will add them as necessary upon input of a term.  Theory
wenzelm@41594
  1464
Complex_Main declares real :: nat => real and real :: int => real as
wenzelm@41594
  1465
coercions. A coercion function f is declared like this:
wenzelm@40939
  1466
wenzelm@40939
  1467
  declare [[coercion f]]
nipkow@40866
  1468
wenzelm@41571
  1469
To lift coercions through type constructors (e.g. from nat => real to
nipkow@40866
  1470
nat list => real list), map functions can be declared, e.g.
nipkow@40866
  1471
wenzelm@40939
  1472
  declare [[coercion_map map]]
wenzelm@40939
  1473
wenzelm@40939
  1474
Currently coercion inference is activated only in theories including
wenzelm@40939
  1475
real numbers, i.e. descendants of Complex_Main.  This is controlled by
wenzelm@41020
  1476
the configuration option "coercion_enabled", e.g. it can be enabled in
wenzelm@40939
  1477
other theories like this:
wenzelm@40939
  1478
wenzelm@40939
  1479
  declare [[coercion_enabled]]
nipkow@40866
  1480
wenzelm@41571
  1481
* Command 'partial_function' provides basic support for recursive
wenzelm@41571
  1482
function definitions over complete partial orders.  Concrete instances
krauss@40183
  1483
are provided for i) the option type, ii) tail recursion on arbitrary
wenzelm@41571
  1484
types, and iii) the heap monad of Imperative_HOL.  See
wenzelm@41571
  1485
src/HOL/ex/Fundefs.thy and src/HOL/Imperative_HOL/ex/Linked_Lists.thy
wenzelm@41571
  1486
for examples.
krauss@40183
  1487
wenzelm@41571
  1488
* Function package: f.psimps rules are no longer implicitly declared
wenzelm@41571
  1489
as [simp].  INCOMPATIBILITY.
haftmann@41398
  1490
haftmann@41398
  1491
* Datatype package: theorems generated for executable equality (class
wenzelm@41571
  1492
"eq") carry proper names and are treated as default code equations.
wenzelm@41571
  1493
wenzelm@41594
  1494
* Inductive package: now offers command 'inductive_simps' to
wenzelm@41594
  1495
automatically derive instantiated and simplified equations for
wenzelm@41594
  1496
inductive predicates, similar to 'inductive_cases'.
wenzelm@41594
  1497
wenzelm@41571
  1498
* Command 'enriched_type' allows to register properties of the
wenzelm@41571
  1499
functorial structure of types.
haftmann@39771
  1500
haftmann@39644
  1501
* Improved infrastructure for term evaluation using code generator
haftmann@39644
  1502
techniques, in particular static evaluation conversions.
haftmann@39644
  1503
wenzelm@41594
  1504
* Code generator: Scala (2.8 or higher) has been added to the target
wenzelm@41594
  1505
languages.
wenzelm@41594
  1506
haftmann@41398
  1507
* Code generator: globbing constant expressions "*" and "Theory.*"
haftmann@41398
  1508
have been replaced by the more idiomatic "_" and "Theory._".
haftmann@41398
  1509
INCOMPATIBILITY.
haftmann@41398
  1510
haftmann@41398
  1511
* Code generator: export_code without explicit file declaration prints
haftmann@41398
  1512
to standard output.  INCOMPATIBILITY.
haftmann@41398
  1513
haftmann@41398
  1514
* Code generator: do not print function definitions for case
haftmann@41398
  1515
combinators any longer.
haftmann@41398
  1516
wenzelm@41594
  1517
* Code generator: simplification with rules determined with
wenzelm@41571
  1518
src/Tools/Code/code_simp.ML and method "code_simp".
wenzelm@41571
  1519
wenzelm@41594
  1520
* Code generator for records: more idiomatic representation of record
wenzelm@40948
  1521
types.  Warning: records are not covered by ancient SML code
wenzelm@40948
  1522
generation any longer.  INCOMPATIBILITY.  In cases of need, a suitable
wenzelm@40948
  1523
rep_datatype declaration helps to succeed then:
haftmann@38537
  1524
haftmann@38537
  1525
  record 'a foo = ...
haftmann@38537
  1526
  ...
haftmann@38537
  1527
  rep_datatype foo_ext ...
haftmann@38535
  1528
wenzelm@41594
  1529
* Records: logical foundation type for records does not carry a
wenzelm@41594
  1530
'_type' suffix any longer (obsolete due to authentic syntax).
wenzelm@41594
  1531
INCOMPATIBILITY.
wenzelm@41594
  1532
haftmann@41398
  1533
* Quickcheck now by default uses exhaustive testing instead of random
wenzelm@41571
  1534
testing.  Random testing can be invoked by "quickcheck [random]",
wenzelm@41571
  1535
exhaustive testing by "quickcheck [exhaustive]".
haftmann@41398
  1536
haftmann@41398
  1537
* Quickcheck instantiates polymorphic types with small finite
haftmann@41398
  1538
datatypes by default. This enables a simple execution mechanism to
haftmann@41398
  1539
handle quantifiers and function equality over the finite datatypes.
haftmann@41398
  1540
wenzelm@41571
  1541
* Quickcheck random generator has been renamed from "code" to
wenzelm@41571
  1542
"random".  INCOMPATIBILITY.
haftmann@41398
  1543
haftmann@41398
  1544
* Quickcheck now has a configurable time limit which is set to 30
haftmann@41398
  1545
seconds by default. This can be changed by adding [timeout = n] to the
haftmann@41398
  1546
quickcheck command. The time limit for Auto Quickcheck is still set
haftmann@41398
  1547
independently.
haftmann@38461
  1548
haftmann@38461
  1549
* Quickcheck in locales considers interpretations of that locale for
haftmann@38461
  1550
counter example search.
haftmann@38461
  1551
blanchet@40059
  1552
* Sledgehammer:
wenzelm@41571
  1553
  - Added "smt" and "remote_smt" provers based on the "smt" proof
wenzelm@41571
  1554
    method. See the Sledgehammer manual for details ("isabelle doc
wenzelm@41571
  1555
    sledgehammer").
blanchet@40059
  1556
  - Renamed commands:
blanchet@40059
  1557
    sledgehammer atp_info ~> sledgehammer running_provers
blanchet@40059
  1558
    sledgehammer atp_kill ~> sledgehammer kill_provers
blanchet@40059
  1559
    sledgehammer available_atps ~> sledgehammer available_provers
blanchet@40059
  1560
    INCOMPATIBILITY.
blanchet@40059
  1561
  - Renamed options:
blanchet@40059
  1562
    sledgehammer [atps = ...] ~> sledgehammer [provers = ...]
blanchet@40062
  1563
    sledgehammer [atp = ...] ~> sledgehammer [prover = ...]
blanchet@40341
  1564
    sledgehammer [timeout = 77 s] ~> sledgehammer [timeout = 77]
blanchet@40341
  1565
    (and "ms" and "min" are no longer supported)
blanchet@40341
  1566
    INCOMPATIBILITY.
blanchet@40341
  1567
blanchet@40341
  1568
* Nitpick:
blanchet@40341
  1569
  - Renamed options:
blanchet@40341
  1570
    nitpick [timeout = 77 s] ~> nitpick [timeout = 77]
blanchet@40341
  1571
    nitpick [tac_timeout = 777 ms] ~> nitpick [tac_timeout = 0.777]
blanchet@40059
  1572
    INCOMPATIBILITY.
blanchet@40725
  1573
  - Added support for partial quotient types.
blanchet@40725
  1574
  - Added local versions of the "Nitpick.register_xxx" functions.
blanchet@40725
  1575
  - Added "whack" option.
blanchet@40725
  1576
  - Allow registration of quotient types as codatatypes.
blanchet@40725
  1577
  - Improved "merge_type_vars" option to merge more types.
blanchet@40725
  1578
  - Removed unsound "fast_descrs" option.
blanchet@40725
  1579
  - Added custom symmetry breaking for datatypes, making it possible to reach
blanchet@40725
  1580
    higher cardinalities.
blanchet@40725

* Proof methods "metis" and "meson" now have configuration options
wenzelm@41571
  1584
"meson_trace", "metis_trace", and "metis_verbose" that can be enabled
wenzelm@41571
  1585
to diagnose these tools. E.g.
wenzelm@41571
  1586
wenzelm@41571
  1587
    using [[metis_trace = true]]
wenzelm@41571
  1588
haftmann@41398
  1589
* Auto Solve: Renamed "Auto Solve Direct".  The tool is now available

  1590
manually as command 'solve_direct'.

boehmes@41601
  1592
* The default SMT solver Z3 must be enabled explicitly (due to
boehmes@41601
  1593
licensing issues) by setting the environment variable
wenzelm@41603
  1594
Z3_NON_COMMERCIAL in etc/settings of the component, for example.  For
wenzelm@41603
  1595
commercial applications, the SMT solver CVC3 is provided as fall-back;
wenzelm@41603
  1596
changing the SMT solver is done via the configuration option
wenzelm@41603
  1597
"smt_solver".
boehmes@41432

boehmes@41432
  1599
* Remote SMT solvers need to be referred to by the "remote_" prefix,
wenzelm@41571

i.e. "remote_cvc3" and "remote_z3".
wenzelm@41571
  1601
wenzelm@41571
  1602
* Added basic SMT support for datatypes, records, and typedefs using
wenzelm@41571
  1603
the oracle mode (no proofs).  Direct support of pairs has been dropped
wenzelm@41571
  1604
in exchange (pass theorems fst_conv snd_conv pair_collapse to the SMT
wenzelm@41571
  1605
support for a similar behavior).  Minor INCOMPATIBILITY.
boehmes@41432
  1606
boehmes@40162

haftmann@41398
  1633
haftmann@41398

  1635
been the case with "split".  INCOMPATIBILITY.
haftmann@41398
  1636

* String.literal is a type, but not a datatype.  INCOMPATIBILITY.
haftmann@41398
  1638
krauss@40388
  1639
* Removed [split_format ... and ... and ...] version of

  1640
[split_format].  Potential INCOMPATIBILITY.
krauss@40388
  1641
wenzelm@41571

haftmann@41398
  1644
haftmann@41398
  1645
* Constant "contents" renamed to "the_elem", to free the generic name
haftmann@41398
  1646
contents for other uses.  INCOMPATIBILITY.
haftmann@41398
  1647
haftmann@41398
  1648
* Renamed class eq and constant eq (for code generation) to class
haftmann@41398
  1649
equal and constant equal, plus renaming of related facts and various
haftmann@41398
  1650
tuning.  INCOMPATIBILITY.
haftmann@41398
  1651
haftmann@41398

INCOMPATIBILITY.
haftmann@41398
  1656
haftmann@41398
  1657
* Renamed theory Fset to Cset, type Fset.fset to Cset.set, in order to

  1658
avoid confusion with finite sets.  INCOMPATIBILITY.
haftmann@41398
  1659
haftmann@41398
  1660
* Abandoned locales equiv, congruent and congruent2 for equivalence
haftmann@41398
  1661
relations.  INCOMPATIBILITY: use equivI rather than equiv_intro (same
haftmann@41398
  1662

  1730
generation.
haftmann@41398

Haskell code.
haftmann@41398
  1734
wenzelm@41571
  1735
* Term "bij f" is now an abbreviation of "bij_betw f UNIV UNIV".  Term
wenzelm@41571
  1736
"surj f" is now an abbreviation of "range f = UNIV".  The theorems
wenzelm@41571
  1737
bij_def and surj_def are unchanged.  INCOMPATIBILITY.
haftmann@41398
  1738
haftmann@41398
  1739
* Abolished some non-alphabetic type names: "prod" and "sum" replace

  1740
"*" and "+" respectively.  INCOMPATIBILITY.
haftmann@41398
  1741
haftmann@41398

  1743
"Sum_Type.Plus" instead.
haftmann@41398
  1744
haftmann@41398
  1745
* Constant "split" has been merged with constant "prod_case"; names of
haftmann@41398
  1746
ML functions, facts etc. involving split have been retained so far,
haftmann@41398
  1747
though.  INCOMPATIBILITY.
haftmann@41398
  1748
haftmann@41398
  1749

instead.  INCOMPATIBILITY.
haftmann@41398
  1751
wenzelm@41571

be euclidean_spaces.  INCOMPATIBILITY.
wenzelm@41594
  1797
wenzelm@41594
  1798
* Session Probability: introduced pextreal as positive extended real
wenzelm@41594
  1799
numbers.  Use pextreal as value for measures.  Introduce the
wenzelm@41594
  1800
Radon-Nikodym derivative, product spaces and Fubini's theorem for
wenzelm@41594
  1801
arbitrary sigma finite measures.  Introduces Lebesgue measure based on

* The domain package now runs in definitional mode by default: The
wenzelm@41571
  1827
former command 'new_domain' is now called 'domain'.  To use the domain
huffman@40621

huffman@40621
  1838
wenzelm@41571
  1839
* The old type class "rep" has been superseded by class "domain".
huffman@40621
  1840
Accordingly, users of the definitional package must remove any
wenzelm@41571

"default_sort rep" declarations.  INCOMPATIBILITY.
huffman@40621
  1842
huffman@41401
  1843
* The domain package (definitional mode) now supports unpointed
huffman@41401
  1844
predomain argument types, as long as they are marked 'lazy'. (Strict
wenzelm@41571
  1845
arguments must be in class "domain".) For example, the following
huffman@41401
  1846
domain definition now works:
huffman@41401

huffman@41401
  1848
  domain natlist = nil | cons (lazy "nat discr") (lazy "natlist")
huffman@41401

  1851
instances for types from main HOL: bool, nat, int, char, 'a + 'b,
wenzelm@41571
  1852
'a option, and 'a list.  Additionally, it configures fixrec and the
wenzelm@41571
  1853
domain package to work with these types.  For example:
huffman@41401
  1854
huffman@41401
  1855
  fixrec isInl :: "('a + 'b) u -> tr"
huffman@41401

huffman@41401
  1857
huffman@41401

  domain V = VFun (lazy "V -> V") | VCon (lazy "nat") (lazy "V list")
huffman@41401
  1859
wenzelm@41571
  1860
* The "(permissive)" option of fixrec has been replaced with a

wenzelm@41571
  1867
* Former type "alg_defl" has been renamed to "defl".  HOLCF no longer

huffman@41401
  1885
* The infix syntax for binary union on each powerdomain has changed
wenzelm@41571
  1886
from e.g. "+\<sharp>" to "\<union>\<sharp>", for consistency with set
wenzelm@41571

syntax.  INCOMPATIBILITY.
wenzelm@41571
  1888
wenzelm@41571

avoid working directly with raw Interrupt.  User code must not absorb
wenzelm@39239
  2066
interrupts -- intermediate handling (for cleanup etc.) needs to be
wenzelm@39239
  2067
followed by re-raising of the original exception.  Another common

wenzelm@35436
  2078
* Authentic syntax for *all* logical entities (type classes, type
wenzelm@35436
  2079
constructors, term constants): provides simple and robust
wenzelm@35436
  2080
correspondence between formal entities and concrete syntax.  Within
wenzelm@35436
  2081
the parse tree / AST representations, "constants" are decorated by
wenzelm@35436
  2082
their category (class, type, const) and spelled out explicitly with
wenzelm@35436
  2083
their full internal name.
wenzelm@35436
  2084
wenzelm@35436
  2085
Substantial INCOMPATIBILITY concerning low-level syntax declarations
wenzelm@35436
  2086
and translations (translation rules and translation functions in ML).
wenzelm@35436
  2087
Some hints on upgrading:
wenzelm@35260
  2088
wenzelm@35260
  2089
  - Many existing uses of 'syntax' and 'translations' can be replaced
wenzelm@35436
  2090
    by more modern 'type_notation', 'notation' and 'abbreviation',
wenzelm@35436
  2091
    which are independent of this issue.
wenzelm@35260
  2092
wenzelm@35260
  2093
  - 'translations' require markup within the AST; the term syntax
wenzelm@35260
  2094
    provides the following special forms:
wenzelm@35260
  2095
wenzelm@35260
  2096
      CONST c   -- produces syntax version of constant c from context
wenzelm@35261
  2097
      XCONST c  -- literally c, checked as constant from context
wenzelm@35261
  2098
      c         -- literally c, if declared by 'syntax'
wenzelm@35261
  2099
wenzelm@35261
  2100
    Plain identifiers are treated as AST variables -- occasionally the
wenzelm@35261
  2101
    system indicates accidental variables via the error "rhs contains
wenzelm@35261
  2102
    extra variables".
wenzelm@35260
  2103
wenzelm@35436
  2104
    Type classes and type constructors are marked according to their
wenzelm@35436
  2105
    concrete syntax.  Some old translations rules need to be written
wenzelm@35436
  2106
    for the "type" category, using type constructor application
wenzelm@35436
  2107
    instead of pseudo-term application of the default category
wenzelm@35436
  2108
    "logic".
wenzelm@35436
  2109
wenzelm@35260
  2110
  - 'parse_translation' etc. in ML may use the following
wenzelm@35260
  2111
    antiquotations:
wenzelm@35260
  2112
wenzelm@35436
  2113
      @{class_syntax c}   -- type class c within parse tree / AST
wenzelm@35436
  2114
      @{term_syntax c}    -- type constructor c within parse tree / AST
wenzelm@35260
  2115
      @{const_syntax c}   -- ML version of "CONST c" above
wenzelm@35260
  2116
      @{syntax_const c}   -- literally c (checked wrt. 'syntax' declarations)
wenzelm@35260
  2117
wenzelm@35436
  2118
  - Literal types within 'typed_print_translations', i.e. those *not*
wenzelm@35436
  2119
    represented as pseudo-terms are represented verbatim.  Use @{class
wenzelm@35436
  2120
    c} or @{type_name c} here instead of the above syntax
wenzelm@35436
  2121
    antiquotations.
wenzelm@35436
  2122
wenzelm@35260
  2123
Note that old non-authentic syntax was based on unqualified base
wenzelm@35436
  2124
names, so all of the above "constant" names would coincide.  Recall
wenzelm@35436
  2125
that 'print_syntax' and ML_command "set Syntax.trace_ast" help to
wenzelm@35436
  2126
diagnose syntax problems.
wenzelm@35260
  2127
wenzelm@35351
  2128
* Type constructors admit general mixfix syntax, not just infix.
wenzelm@35351
  2129
wenzelm@36508
  2130
* Concrete syntax may be attached to local entities without a proof
wenzelm@36508
  2131
body, too.  This works via regular mixfix annotations for 'fix',
wenzelm@36508
  2132
'def', 'obtain' etc. or via the explicit 'write' command, which is
wenzelm@36508
  2133
similar to the 'notation' command in theory specifications.
wenzelm@36508
  2134
wenzelm@37351
  2135
* Discontinued unnamed infix syntax (legacy feature for many years) --
wenzelm@37351
  2136
need to specify constant name and syntax separately.  Internal ML
wenzelm@37351
  2137
datatype constructors have been renamed from InfixName to Infix etc.
wenzelm@37351
  2138
Minor INCOMPATIBILITY.
wenzelm@37351
  2139
wenzelm@37351
  2140
* Schematic theorem statements need to be explicitly markup as such,
wenzelm@37351
  2141
via commands 'schematic_lemma', 'schematic_theorem',
wenzelm@37351
  2142
'schematic_corollary'.  Thus the relevance of the proof is made
wenzelm@37351
  2143
syntactically clear, which impacts performance in a parallel or
wenzelm@37351
  2144
asynchronous interactive environment.  Minor INCOMPATIBILITY.
wenzelm@37351
  2145
wenzelm@35613
  2146
* Use of cumulative prems via "!" in some proof methods has been
wenzelm@37351
  2147
discontinued (old legacy feature).
wenzelm@35613
  2148
boehmes@35979
  2149
* References 'trace_simp' and 'debug_simp' have been replaced by
wenzelm@36857
  2150
configuration options stored in the context. Enabling tracing (the
wenzelm@36857
  2151
case of debugging is similar) in proofs works via
wenzelm@36857
  2152
wenzelm@36857
  2153
  using [[trace_simp = true]]
wenzelm@36857
  2154
wenzelm@36857
  2155
Tracing is then active for all invocations of the simplifier in
wenzelm@36857
  2156
subsequent goal refinement steps. Tracing may also still be enabled or
wenzelm@40780
  2157
disabled via the ProofGeneral settings menu.
boehmes@35979
  2158
wenzelm@36177
  2159
* Separate commands 'hide_class', 'hide_type', 'hide_const',
wenzelm@36177
  2160
'hide_fact' replace the former 'hide' KIND command.  Minor
wenzelm@36177
  2161
INCOMPATIBILITY.
wenzelm@36177
  2162
wenzelm@37298
  2163
* Improved parallelism of proof term normalization: usedir -p2 -q0 is
wenzelm@37298
  2164
more efficient than combinations with -q1 or -q2.

wenzelm@37351

* Proofterms record type-class reasoning explicitly, using the
wenzelm@37351
  2170
"unconstrain" operation internally.  This eliminates all sort
wenzelm@37351
  2171
constraints from a theorem and proof, introducing explicit
wenzelm@37351
  2172
OFCLASS-premises.  On the proof term level, this operation is
wenzelm@37351
  2173
automatically applied at theorem boundaries, such that closed proofs
wenzelm@37351
  2174
are always free of sort constraints.  INCOMPATIBILITY for tools that
wenzelm@37351
  2175
inspect proof terms.
haftmann@36147
  2176
wenzelm@35765
  2177
* Local theory specifications may depend on extra type variables that
wenzelm@35765
  2178
are not present in the result type -- arguments TYPE('a) :: 'a itself
wenzelm@35765
  2179
are added internally.  For example:
wenzelm@35765
  2180
wenzelm@35765
  2181
  definition unitary :: bool where "unitary = (ALL (x::'a) y. x = y)"
wenzelm@35765
  2182
wenzelm@37351
  2183
* Predicates of locales introduced by classes carry a mandatory
wenzelm@37351
  2184
"class" prefix.  INCOMPATIBILITY.
wenzelm@37351
  2185
wenzelm@37351
  2186
* Vacuous class specifications observe default sort.  INCOMPATIBILITY.
wenzelm@37351
  2187
wenzelm@37351
  2188
* Old 'axclass' command has been discontinued.  INCOMPATIBILITY, use
wenzelm@37351
  2189
'class' instead.
wenzelm@37351
  2190
wenzelm@37351
  2191
* Command 'code_reflect' allows to incorporate generated ML code into
wenzelm@37351
  2192
runtime environment; replaces immature code_datatype antiquotation.
wenzelm@37351
  2193
INCOMPATIBILITY.

wenzelm@37351

  2199
user space functionality any longer.
wenzelm@36857
  2200
wenzelm@37351
  2201
* Methods "unfold_locales" and "intro_locales" ignore non-locale
wenzelm@37351
  2202
subgoals.  This is more appropriate for interpretations with 'where'.
wenzelm@36857
  2203
INCOMPATIBILITY.
haftmann@34170

wenzelm@36356

* Command 'example_proof' opens an empty proof body.  This allows to
wenzelm@36356
  2206
experiment with Isar, without producing any persistent result.
wenzelm@36356
  2207
wenzelm@35413
  2208
* Commands 'type_notation' and 'no_type_notation' declare type syntax
wenzelm@35413

within a local theory context, with explicit checking of the
wenzelm@35413
  2210
constructors involved (in contrast to the raw 'syntax' versions).
wenzelm@35413
  2211
wenzelm@36178
  2212
* Commands 'types' and 'typedecl' now work within a local theory
wenzelm@36178

context -- without introducing dependencies on parameters or
wenzelm@36178
  2214
assumptions, which is not possible in Isabelle/Pure.
wenzelm@35681
  2215
wenzelm@36857

* Command 'typedef' now works within a local theory context -- without
wenzelm@37351
  2223
introducing dependencies on parameters or assumptions, which is not
wenzelm@37351
  2224
possible in Isabelle/Pure/HOL.  Note that the logical environment may
wenzelm@37351
  2225
contain multiple interpretations of local typedefs (with different
wenzelm@37351
  2226
non-emptiness proofs), even in a global theory context.
wenzelm@37351
  2227
wenzelm@37351
  2228
* New package for quotient types.  Commands 'quotient_type' and
wenzelm@37351
  2229
'quotient_definition' may be used for defining types and constants by
wenzelm@37351
  2230
quotient constructions.  An example is the type of integers created by
wenzelm@37351
  2231
quotienting pairs of natural numbers:
wenzelm@37380
  2232
wenzelm@37351
  2233
  fun
wenzelm@37380
  2234
    intrel :: "(nat * nat) => (nat * nat) => bool"

    "intrel (x, y) (u, v) = (x + v = u + y)"
wenzelm@37351
  2237
wenzelm@37380
  2238
  quotient_type int = "nat * nat" / intrel
wenzelm@37351

wenzelm@37351
  2241
  quotient_definition

    "0::int" is "(0::nat, 0::nat)"
wenzelm@37351
  2243
wenzelm@37351
  2244
The method "lifting" can be used to lift of theorems from the
wenzelm@37351
  2245
underlying "raw" type to the quotient type.  The example
wenzelm@37351
  2246
src/HOL/Quotient_Examples/FSet.thy includes such a quotient
wenzelm@37351
  2247
construction and provides a reasoning infrastructure for finite sets.
wenzelm@37351
  2248
wenzelm@37351
  2249
* Renamed Library/Quotient.thy to Library/Quotient_Type.thy to avoid

wenzelm@37351
  2251

  - classes division_ring_inverse_zero, field_inverse_zero,
wenzelm@36857
  2400
    linordered_field_inverse_zero include rule inverse 0 = 0 --
wenzelm@36857

haftmann@36416
  2404
haftmann@36416
  2405
* Refined algebra theorem collections:
wenzelm@36857
  2406
  - dropped theorem group group_simps, use algebra_simps instead;
wenzelm@36857
  2407
  - dropped theorem group ring_simps, use field_simps instead;
wenzelm@36857
  2408
  - proper theorem collection field_simps subsumes former theorem
wenzelm@36857
  2409
    groups field_eq_simps and field_simps;
wenzelm@36857
  2410
  - dropped lemma eq_minus_self_iff which is a duplicate for
wenzelm@36857
  2411
    equal_neg_zero.
wenzelm@36857
  2412
INCOMPATIBILITY.
wenzelm@35009

wenzelm@44973
  2429
replaced by the more convenient lemmas Inf_empty and Sup_empty.
wenzelm@44973
  2430
Dropped lemmas Inf_insert_simp and Sup_insert_simp, which are subsumed
wenzelm@44973
  2431
by Inf_insert and Sup_insert.  Lemmas Inf_UNIV and Sup_UNIV replace
wenzelm@44973
  2432
former Inf_Univ and Sup_Univ.  Lemmas inf_top_right and sup_bot_right
wenzelm@44973

wenzelm@36857
  2435
* Reorganized theory Multiset: swapped notation of pointwise and
wenzelm@36857
  2436
multiset order:
wenzelm@37351
  2437
wenzelm@36857
  2438
  - pointwise ordering is instance of class order with standard syntax
wenzelm@36857
  2439
    <= and <;
wenzelm@36857
  2440
  - multiset ordering has syntax <=# and <#; partial order properties
wenzelm@36857
  2441
    are provided by means of interpretation with prefix
wenzelm@36857
  2442
    multiset_order;
wenzelm@36857
  2443
  - less duplication, less historical organization of sections,
wenzelm@36857
  2444
    conversion from associations lists to multisets, rudimentary code
wenzelm@36857
  2445
    generation;
wenzelm@36857
  2446
  - use insert_DiffM2 [symmetric] instead of elem_imp_eq_diff_union,
wenzelm@36857
  2447
    if needed.

blanchet@36929
  2504
    INCOMPATIBILITY.
blanchet@36929
  2505
  - Added user's manual ("isabelle doc sledgehammer").
blanchet@36929
  2506
  - Added option syntax and "sledgehammer_params" to customize
blanchet@36929
  2507
    Sledgehammer's behavior.  See the manual for details.
blanchet@36929
  2508
  - Modified the Isar proof reconstruction code so that it produces
blanchet@36929
  2509
    direct proofs rather than proofs by contradiction.  (This feature
blanchet@36929
  2510
    is still experimental.)
blanchet@36929
  2511
  - Made Isar proof reconstruction work for SPASS, remote ATPs, and in
blanchet@36929
  2512
    full-typed mode.
blanchet@36929
  2513
  - Added support for TPTP syntax for SPASS via the "spass_tptp" ATP.
blanchet@36929
  2514
blanchet@36928
  2515
* Nitpick:
blanchet@36928
  2516
  - Added and implemented "binary_ints" and "bits" options.
blanchet@36928
  2517
  - Added "std" option and implemented support for nonstandard models.
blanchet@36928
  2518
  - Added and implemented "finitize" option to improve the precision
blanchet@36928
  2519
    of infinite datatypes based on a monotonicity analysis.
blanchet@36928
  2520
  - Added support for quotient types.
blanchet@36928
  2521
  - Added support for "specification" and "ax_specification"
blanchet@36928
  2522
    constructs.
blanchet@36928
  2523
  - Added support for local definitions (for "function" and
blanchet@36928
  2524
    "termination" proofs).
blanchet@36928
  2525
  - Added support for term postprocessors.
blanchet@36928
  2526
  - Optimized "Multiset.multiset" and "FinFun.finfun".
blanchet@36928
  2527
  - Improved efficiency of "destroy_constrs" optimization.
blanchet@36928
  2528
  - Fixed soundness bugs related to "destroy_constrs" optimization and
blanchet@36928
  2529
    record getters.
blanchet@37272
  2530
  - Fixed soundness bug related to higher-order constructors.
blanchet@37272
  2531
  - Fixed soundness bug when "full_descrs" is enabled.
blanchet@36928
  2532
  - Improved precision of set constructs.
blanchet@37260
  2533
  - Added "atoms" option.
blanchet@36928
  2534
  - Added cache to speed up repeated Kodkod invocations on the same
blanchet@36928
  2535
    problems.
blanchet@36928
  2536
  - Renamed "MiniSatJNI", "zChaffJNI", "BerkMinAlloy", and
blanchet@36928
  2537
    "SAT4JLight" to "MiniSat_JNI", "zChaff_JNI", "BerkMin_Alloy", and
blanchet@36928
  2538
    "SAT4J_Light".  INCOMPATIBILITY.
blanchet@36928
  2539
  - Removed "skolemize", "uncurry", "sym_break", "flatten_prop",
blanchet@36928
  2540
    "sharing_depth", and "show_skolems" options.  INCOMPATIBILITY.
blanchet@37264

* Method "induct" now takes instantiations of the form t, where t is not
berghofe@37361
  2544
  a variable, as a shorthand for "x == t", where x is a fresh variable.
berghofe@37361
  2545
  If this is not intended, t has to be enclosed in parentheses.
berghofe@37361
  2546
  By default, the equalities generated by definitional instantiations
berghofe@37361
  2547
  are pre-simplified, which may cause parameters of inductive cases
berghofe@37361
  2548
  to disappear, or may even delete some of the inductive cases.
berghofe@37361
  2549
  Use "induct (no_simp)" instead of "induct" to restore the old
berghofe@37361
  2550
  behaviour. The (no_simp) option is also understood by the "cases"
berghofe@37361
  2551
  and "nominal_induct" methods, which now perform pre-simplification, too.
berghofe@37361

* Variable names in lemmas generated by the domain package have
huffman@36828

huffman@36828

recursive domain "foo".  The reach lemma is now stated directly in
huffman@36828

* Antiquotations for basic formal entities:
wenzelm@37351
  2614
wenzelm@37351
  2615
    @{class NAME}         -- type class
wenzelm@37351
  2616
    @{class_syntax NAME}  -- syntax representation of the above
wenzelm@37351
  2617
wenzelm@37351
  2618
    @{type_name NAME}     -- logical type
wenzelm@37351
  2619
    @{type_abbrev NAME}   -- type abbreviation
wenzelm@37351
  2620
    @{nonterminal NAME}   -- type of concrete syntactic category
wenzelm@37351
  2621
    @{type_syntax NAME}   -- syntax representation of any of the above
wenzelm@37351
  2622
wenzelm@37351
  2623
    @{const_name NAME}    -- logical constant (INCOMPATIBILITY)
wenzelm@37351
  2624
    @{const_abbrev NAME}  -- abbreviated constant
wenzelm@37351
  2625
    @{const_syntax NAME}  -- syntax representation of any of the above
wenzelm@37351
  2626
wenzelm@37351
  2627
* Antiquotation @{syntax_const NAME} ensures that NAME refers to a raw
wenzelm@37351
  2628
syntax constant (cf. 'syntax' command).
wenzelm@37351
  2629
wenzelm@37351
  2630
* Antiquotation @{make_string} inlines a function to print arbitrary
wenzelm@37351
  2631
values similar to the ML toplevel.  The result is compiler dependent
wenzelm@37351
  2632
and may fall back on "?" in certain situations.
wenzelm@37351
  2633
wenzelm@37351
  2634
* Diagnostic commands 'ML_val' and 'ML_command' may refer to
wenzelm@37351
  2635
antiquotations @{Isar.state} and @{Isar.goal}.  This replaces impure
wenzelm@37351
  2636
Isar.state() and Isar.goal(), which belong to the old TTY loop and do
wenzelm@37351
  2637
not work with the asynchronous Isar document model.
wenzelm@37351
  2638
wenzelm@37351
  2639
* Configuration options now admit dynamic default values, depending on
wenzelm@37351
  2640
the context or even global references.
wenzelm@37351
  2641
wenzelm@37351
  2642
* SHA1.digest digests strings according to SHA-1 (see RFC 3174).  It
wenzelm@37351
  2643
uses an efficient external library if available (for Poly/ML).
wenzelm@37351
  2644
wenzelm@37144
  2645
* Renamed some important ML structures, while keeping the old names
wenzelm@37144
  2646
for some time as aliases within the structure Legacy:
wenzelm@37144
  2647
wenzelm@37144
  2648
  OuterKeyword  ~>  Keyword
wenzelm@37144
  2649
  OuterLex      ~>  Token
wenzelm@37144
  2650
  OuterParse    ~>  Parse
wenzelm@37144
  2651
  OuterSyntax   ~>  Outer_Syntax
wenzelm@37216
  2652
  PrintMode     ~>  Print_Mode
wenzelm@37144
  2653
  SpecParse     ~>  Parse_Spec
wenzelm@37216
  2654
  ThyInfo       ~>  Thy_Info
wenzelm@37216
  2655
  ThyLoad       ~>  Thy_Load
wenzelm@37216
  2656
  ThyOutput     ~>  Thy_Output
wenzelm@37145
  2657
  TypeInfer     ~>  Type_Infer
wenzelm@37144
  2658
wenzelm@37144
  2659
Note that "open Legacy" simplifies porting of sources, but forgetting
wenzelm@37144
  2660
to remove it again will complicate porting again in the future.
wenzelm@37144
  2661
wenzelm@37144
  2662
* Most operations that refer to a global context are named
wenzelm@37144
  2663
accordingly, e.g. Simplifier.global_context or
wenzelm@37144
  2664
ProofContext.init_global.  There are some situations where a global
wenzelm@37144
  2665
context actually works, but under normal circumstances one needs to
wenzelm@37144
  2666
pass the proper local context through the code!
wenzelm@37144
  2667
wenzelm@37144
  2668
* Discontinued old TheoryDataFun with its copy/init operation -- data
wenzelm@37144
  2669
needs to be pure.  Functor Theory_Data_PP retains the traditional
wenzelm@37144
  2670
Pretty.pp argument to merge, which is absent in the standard
wenzelm@37144
  2671
Theory_Data version.
wenzelm@36429
  2672
wenzelm@37144
  2673
* Sorts.certify_sort and derived "cert" operations for types and terms
wenzelm@37144
  2674
no longer minimize sorts.  Thus certification at the boundary of the
wenzelm@37144
  2675
inference kernel becomes invariant under addition of class relations,
wenzelm@37144
  2676
which is an important monotonicity principle.  Sorts are now minimized
wenzelm@37144
  2677
in the syntax layer only, at the boundary between the end-user and the
wenzelm@37144
  2678
system.  Subtle INCOMPATIBILITY, may have to use Sign.minimize_sort
wenzelm@37144
  2679
explicitly in rare situations.
wenzelm@37144
  2680
wenzelm@35021
  2681
* Renamed old-style Drule.standard to Drule.export_without_context, to
wenzelm@35021
  2682
emphasize that this is in no way a standard operation.
wenzelm@35021
  2683
INCOMPATIBILITY.
wenzelm@35021
  2684
wenzelm@34076
  2685
* Subgoal.FOCUS (and variants): resulting goal state is normalized as
wenzelm@34076
  2686
usual for resolution.  Rare INCOMPATIBILITY.
wenzelm@34076
  2687
wenzelm@35845
  2688
* Renamed varify/unvarify operations to varify_global/unvarify_global
wenzelm@35845
  2689
to emphasize that these only work in a global situation (which is
wenzelm@35845
  2690
quite rare).
