*** 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@47113
    50
* ISABELLE_JDK_HOME settings variable points to JDK with javac and jar
wenzelm@47185
    51
(not just JRE).
wenzelm@47113
    52
wenzelm@45593
    53
wenzelm@45134
    54
*** Pure ***
wenzelm@45134
    55
wenzelm@47427
    56
* Rule composition via attribute "OF" (or ML functions OF/MRS) is more
wenzelm@47427
    57
tolerant against multiple unifiers, as long as the final result is
wenzelm@47427
    58
unique.  (As before, rules are composed in canonical right-to-left
wenzelm@47427
    59
order to accommodate newly introduced premises.)
wenzelm@47427
    60
wenzelm@46976
    61
* Command 'definition' no longer exports the foundational "raw_def"
wenzelm@46976
    62
into the user context.  Minor INCOMPATIBILITY, may use the regular
wenzelm@46976
    63
"def" result with attribute "abs_def" to imitate the old version.
wenzelm@46976
    64
wenzelm@46903
    65
* Attribute "abs_def" turns an equation of the form "f x y == t" into
wenzelm@46903
    66
"f == %x y. t", which ensures that "simp" or "unfold" steps always
wenzelm@46903
    67
expand it.  This also works for object-logic equality.  (Formerly
wenzelm@46903
    68
undocumented feature.)
wenzelm@46903
    69
wenzelm@46493
    70
* Discontinued old "prems" fact, which used to refer to the accidental
wenzelm@46493
    71
collection of foundational premises in the context (marked as legacy
wenzelm@46493
    72
since Isabelle2011).
wenzelm@46493
    73
wenzelm@45134
    74
* Obsolete command 'types' has been discontinued.  Use 'type_synonym'
wenzelm@45134
    75
instead.  INCOMPATIBILITY.
wenzelm@45134
    76
bulwahn@45191
    77
* Ancient code generator for SML and its commands 'code_module',
wenzelm@45383
    78
'code_library', 'consts_code', 'types_code' have been discontinued.
haftmann@46028
    79
Use commands of the generic code generator instead.  INCOMPATIBILITY.
wenzelm@45383
    80
wenzelm@45383
    81
* Redundant attribute 'code_inline' has been discontinued. Use
haftmann@46028
    82
'code_unfold' instead.  INCOMPATIBILITY.
haftmann@46028
    83
wenzelm@46160
    84
* Dropped attribute 'code_unfold_post' in favor of the its dual
wenzelm@46160
    85
'code_abbrev', which yields a common pattern in definitions like
haftmann@46028
    86
haftmann@46028
    87
  definition [code_abbrev]: "f = t"
haftmann@46028
    88
haftmann@46028
    89
INCOMPATIBILITY.
wenzelm@45383
    90
wenzelm@45427
    91
* Sort constraints are now propagated in simultaneous statements, just
wenzelm@45427
    92
like type constraints.  INCOMPATIBILITY in rare situations, where
wenzelm@45427
    93
distinct sorts used to be assigned accidentally.  For example:
wenzelm@45427
    94
wenzelm@45427
    95
  lemma "P (x::'a::foo)" and "Q (y::'a::bar)"  -- "now illegal"
wenzelm@45427
    96
wenzelm@45427
    97
  lemma "P (x::'a)" and "Q (y::'a::bar)"
wenzelm@45427
    98
    -- "now uniform 'a::bar instead of default sort for first occurence (!)"
wenzelm@45427
    99
wenzelm@45427

huffman@45122

*** HOL ***
huffman@45122
   102
nipkow@47270
   103
* New tutorial Programming and Proving in Isabelle/HOL
nipkow@47270
   104
huffman@47108
   105
* The representation of numerals has changed. We now have a datatype
huffman@47108
   106
"num" representing strictly positive binary numerals, along with
huffman@47108
   107
functions "numeral :: num => 'a" and "neg_numeral :: num => 'a" to
huffman@47108
   108
represent positive and negated numeric literals, respectively. (See
huffman@47108
   109
definitions in Num.thy.) Potential INCOMPATIBILITY; some user theories
huffman@47108
   110
may require adaptations:
huffman@47108
   111
huffman@47108
   112
  - Theorems with number_ring or number_semiring constraints: These
huffman@47108
   113
    classes are gone; use comm_ring_1 or comm_semiring_1 instead.
huffman@47108
   114
huffman@47108
   115
  - Theories defining numeric types: Remove number, number_semiring,
huffman@47108
   116
    and number_ring instances. Defer all theorems about numerals until
huffman@47108
   117
    after classes one and semigroup_add have been instantiated.
huffman@47108
   118
huffman@47108
   119
  - Numeral-only simp rules: Replace each rule having a "number_of v"
huffman@47108
   120
    pattern with two copies, one for numeral and one for neg_numeral.
huffman@47108
   121
huffman@47108
   122
  - Theorems about subclasses of semiring_1 or ring_1: These classes
huffman@47108
   123
    automatically support numerals now, so more simp rules and
huffman@47108
   124
    simprocs may now apply within the proof.
huffman@47108
   125
huffman@47108
   126
  - Definitions and theorems using old constructors Pls/Min/Bit0/Bit1:
huffman@47108
   127
    Redefine using other integer operations.
huffman@47108
   128
wenzelm@46160
   129
* Type 'a set is now a proper type constructor (just as before
wenzelm@46160
   130
Isabelle2008).  Definitions mem_def and Collect_def have disappeared.
wenzelm@46160
   131
Non-trivial INCOMPATIBILITY.  For developments keeping predicates and
wenzelm@46160
   132
sets separate, it is often sufficient to rephrase sets S accidentally
wenzelm@46160
   133
used as predicates by "%x. x : S" and predicates P accidentally used
wenzelm@46160
   134
as sets by "{x. P x}".  Corresponding proofs in a first step should be
wenzelm@46160
   135
pruned from any tinkering with former theorems mem_def and
haftmann@46834
   136
Collect_def as far as possible.
haftmann@46834
   137
For developments which deliberately mixed predicates and
wenzelm@46160
   138
sets, a planning step is necessary to determine what should become a
wenzelm@46160
   139
predicate and what a set.  It can be helpful to carry out that step in
wenzelm@46160
   140
Isabelle2011-1 before jumping right into the current release.
wenzelm@46160
   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.
krauss@47265
   147
Removed 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

   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
haftmann@47202
   181
and predicates.  Added powers of predicate relations.
haftmann@47202
   182
Consolidation 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
haftmann@47086
   193
See theory "Relation" for examples for making use of pred/set conversions
haftmann@47086
   194
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

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

  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"
haftmann@47397
   232
and "List.foldl plus 0", prefer "List.listsum".  Otherwise it can
haftmann@47397
   233
be useful to boil down "List.foldr" and "List.foldl" to "List.fold"
haftmann@47399
   234
by 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

* New "case_product" attribute to generate a case rule doing multiple
wenzelm@45383
   550
case distinctions at the same time.  E.g.
wenzelm@45383
   551
wenzelm@45383
   552
  list.exhaust [case_product nat.exhaust]
wenzelm@45383
   553
wenzelm@45383
   554
produces a rule which can be used to perform case distinction on both
wenzelm@45383
   555
a list and a nat.
wenzelm@45383
   556
bulwahn@46170
   557
* Improved code generation of multisets.
bulwahn@46170
   558
bulwahn@46591
   559
* New diagnostic command find_unused_assms to find potentially superfluous
bulwahn@46591
   560
  assumptions in theorems using Quickcheck.
bulwahn@46591
   561
bulwahn@45759
   562
* Quickcheck:
bulwahn@45759
   563
  - Quickcheck returns variable assignments as counterexamples, which
bulwahn@45759
   564
    allows to reveal the underspecification of functions under test.
bulwahn@45759
   565
    For example, refuting "hd xs = x", it presents the variable
bulwahn@45759
   566
    assignment xs = [] and x = a1 as a counterexample, assuming that
bulwahn@45759
   567
    any property is false whenever "hd []" occurs in it.
bulwahn@45759
   568
    These counterexample are marked as potentially spurious, as
bulwahn@45759
   569
    Quickcheck also returns "xs = []" as a counterexample to the
bulwahn@45759
   570
    obvious theorem "hd xs = hd xs".
bulwahn@45759
   571
    After finding a potentially spurious counterexample, Quickcheck
bulwahn@45759
   572
    continues searching for genuine ones.
bulwahn@45759
   573
    By default, Quickcheck shows potentially spurious and genuine
bulwahn@45759
   574
    counterexamples. The option "genuine_only" sets quickcheck to
bulwahn@45759
   575
    only show genuine counterexamples.
bulwahn@45941
   576
bulwahn@45941
   577
  - The command 'quickcheck_generator' creates random and exhaustive
bulwahn@45941
   578
    value generators for a given type and operations.
bulwahn@45941
   579
    It generates values by using the operations as if they were
bulwahn@45941
   580
    constructors of that type. 
bulwahn@46170
   581
bulwahn@46170
   582
  - Support for multisets.
bulwahn@46170
   583
bulwahn@46591
   584
  - Added "use_subtype" options.
bulwahn@47349
   585
  - Added "quickcheck_locale" configuration to specify how to process
bulwahn@47349
   586
    conjectures in a locale context.
bulwahn@47349
   587
blanchet@45398
   588
* Nitpick:
blanchet@45516
   589
  - Fixed infinite loop caused by the 'peephole_optim' option and
blanchet@45516
   590
    affecting 'rat' and 'real'.
blanchet@45516
   591
blanchet@45516
   592
* Sledgehammer:
blanchet@46409
   593
  - Added "lam_trans", "uncurry_aliases", and "minimize" options.
blanchet@45706
   594
  - Renamed "slicing" ("no_slicing") option to "slice" ("dont_slice").
blanchet@46301
   595
  - Renamed "sound" option to "strict".
blanchet@45516
   596
blanchet@45516
   597
* Metis:
blanchet@45516
   598
  - Added possibility to specify lambda translations scheme as a
blanchet@46366
   599
    parenthesized argument (e.g., "by (metis (lifting) ...)").
blanchet@45398
   600
bulwahn@47197
   601
* SMT:
bulwahn@47197
   602
  - renamed "smt_fixed" option to "smt_read_only_certificates".
bulwahn@47197
   603
 
blanchet@46641
   604
* Command 'try0':
blanchet@46641
   605
  - Renamed from 'try_methods'. INCOMPATIBILITY.
blanchet@46641
   606
noschinl@46888
   607
* New "eventually_elim" method as a generalized variant of the
noschinl@46888
   608
  eventually_elim* rules. Supports structured proofs.
noschinl@46888
   609
wenzelm@47413
   610
* HOL/TPTP: support to parse and import TPTP problems (all languages)

* Antiquotation @{keyword "name"} produces a parser for outer syntax
wenzelm@46948
   622
from a minor keyword introduced via theory header declaration.
wenzelm@46948
   623
wenzelm@46961
   624
* Antiquotation @{command_spec "name"} produces the
wenzelm@46961
   625
Outer_Syntax.command_spec from a major keyword introduced via theory
wenzelm@46961
   626
header declaration; it can be passed to Outer_Syntax.command etc.
wenzelm@46961
   627
wenzelm@46916
   628
* Local_Theory.define no longer hard-wires default theorem name
wenzelm@46992
   629
"foo_def", but retains the binding as given.  If that is Binding.empty
wenzelm@46992
   630
/ Attrib.empty_binding, the result is not registered as user-level
wenzelm@46992
   631
fact.  The Local_Theory.define_internal variant allows to specify a
wenzelm@46992
   632
non-empty name (used for the foundation in the background theory),
wenzelm@46992
   633
while omitting the fact binding in the user-context.  Potential
wenzelm@46992
   634
INCOMPATIBILITY for derived definitional packages: need to specify
wenzelm@46992
   635
naming policy for primitive definitions more explicitly.
wenzelm@46916
   636
wenzelm@46497
   637
* Renamed Thm.capply to Thm.apply, and Thm.cabs to Thm.lambda in
wenzelm@46497
   638
conformance with similar operations in structure Term and Logic.
wenzelm@46497
   639
wenzelm@45592
   640
* Antiquotation @{attributes [...]} embeds attribute source
wenzelm@45592
   641
representation into the ML text, which is particularly useful with
wenzelm@45592
   642
declarations like Local_Theory.note.
wenzelm@45592
   643
wenzelm@45128
   644
* Structure Proof_Context follows standard naming scheme.  Old
wenzelm@45128
   645
ProofContext has been discontinued.  INCOMPATIBILITY.
wenzelm@45128
   646
wenzelm@45293
   647
* Refined Local_Theory.declaration {syntax, pervasive}, with subtle
wenzelm@45298
   648
change of semantics: update is applied to auxiliary local theory
wenzelm@45293
   649
context as well.
wenzelm@45293
   650
wenzelm@45620

*** General ***
wenzelm@41703
   678
wenzelm@44760
   679
* Improved Isabelle/jEdit Prover IDE (PIDE), which can be invoked as
wenzelm@44968
   680
"isabelle jedit" or "ISABELLE_HOME/Isabelle" on the command line.
wenzelm@44760
   681
wenzelm@44777
   682
  - Management of multiple theory files directly from the editor
wenzelm@44760
   683
    buffer store -- bypassing the file-system (no requirement to save
wenzelm@44760
   684
    files for checking).
wenzelm@44760
   685
wenzelm@44777
   686
  - Markup of formal entities within the text buffer, with semantic
wenzelm@44760
   687
    highlighting, tooltips and hyperlinks to jump to defining source
wenzelm@44760
   688
    positions.
wenzelm@44760
   689
wenzelm@44777
   690
  - Improved text rendering, with sub/superscripts in the source
wenzelm@44777
   691
    buffer (including support for copy/paste wrt. output panel, HTML
wenzelm@44777
   692
    theory output and other non-Isabelle text boxes).
wenzelm@44777
   693
wenzelm@44777
   694
  - Refined scheduling of proof checking and printing of results,
wenzelm@44760
   695
    based on interactive editor view.  (Note: jEdit folding and
wenzelm@44760
   696
    narrowing allows to restrict buffer perspectives explicitly.)
wenzelm@44760
   697
wenzelm@44777
   698
  - Reduced CPU performance requirements, usable on machines with few
wenzelm@44760
   699
    cores.
wenzelm@44760
   700
wenzelm@44777
   701
  - Reduced memory requirements due to pruning of unused document
wenzelm@44760
   702
    versions (garbage collection).
wenzelm@44760
   703
wenzelm@44760

See also ~~/src/Tools/jEdit/README.html for further information,

   705
including some remaining limitations.
wenzelm@44760
   706
wenzelm@44800
   707
* Theory loader: source files are exclusively located via the master
wenzelm@44800
   708
directory of each theory node (where the .thy file itself resides).
wenzelm@44800
   709
The global load path (such as src/HOL/Library) has been discontinued.
wenzelm@44800
   710
Note that the path element ~~ may be used to reference theories in the
wenzelm@44800
   711
Isabelle home folder -- for instance, "~~/src/HOL/Library/FuncSet".
wenzelm@44800
   712
INCOMPATIBILITY.
wenzelm@44800
   713
wenzelm@41955
   714
* Theory loader: source files are identified by content via SHA1
wenzelm@41955
   715
digests.  Discontinued former path/modtime identification and optional
wenzelm@41955
   716
ISABELLE_FILE_IDENT plugin scripts.
wenzelm@41955
   717
wenzelm@41703
   718
* Parallelization of nested Isar proofs is subject to
wenzelm@41703
   719
Goal.parallel_proofs_threshold (default 100).  See also isabelle
wenzelm@41703
   720
usedir option -Q.
wenzelm@41703
   721
wenzelm@42669
   722
* Name space: former unsynchronized references are now proper
wenzelm@42669
   723
configuration options, with more conventional names:
wenzelm@42669
   724
wenzelm@42669
   725
  long_names   ~> names_long
wenzelm@42669
   726
  short_names  ~> names_short
wenzelm@42669
   727
  unique_names ~> names_unique
wenzelm@42669
   728
wenzelm@42669
   729
Minor INCOMPATIBILITY, need to declare options in context like this:
wenzelm@42669
   730
wenzelm@42669
   731
  declare [[names_unique = false]]
wenzelm@42358
   732
wenzelm@42502
   733
* Literal facts `prop` may contain dummy patterns, e.g. `_ = _`.  Note
wenzelm@42502
   734
that the result needs to be unique, which means fact specifications
wenzelm@42502
   735
may have to be refined after enriching a proof context.
wenzelm@42502
   736
wenzelm@44800
   737
* Attribute "case_names" has been refined: the assumptions in each case
wenzelm@44800
   738
can be named now by following the case name with [name1 name2 ...].
wenzelm@44800
   739
wenzelm@44968
   740
* Isabelle/Isar reference manual has been updated and extended:
wenzelm@44968
   741
  - "Synopsis" provides a catalog of main Isar language concepts.
wenzelm@44968
   742
  - Formal references in syntax diagrams, via @{rail} antiquotation.
wenzelm@44968
   743
  - Updated material from classic "ref" manual, notably about

generalized.  Now it is defined on the type class {topological_space,
wenzelm@44967

wenzelm@42484
   934
huffman@44908
   935
* Theory Complex_Main: The complex exponential function "expi" is now
huffman@44908
   936
a type-constrained abbreviation for "exp :: complex => complex"; thus
huffman@44908
   937
several polymorphic lemmas about "exp" are now applicable to "expi".
huffman@44908
   938
wenzelm@44968
   939
* Code generation:
wenzelm@44968
   940
wenzelm@44968
   941
  - Theory Library/Code_Char_ord provides native ordering of
wenzelm@44968
   942
    characters in the target language.
wenzelm@44968
   943
wenzelm@44968
   944
  - Commands code_module and code_library are legacy, use export_code
wenzelm@44968
   945
    instead.
wenzelm@44968
   946
wenzelm@44968
   947
  - Method "evaluation" is legacy, use method "eval" instead.
wenzelm@44968
   948
wenzelm@44968
   949
  - Legacy evaluator "SML" is deactivated by default.  May be
wenzelm@44968
   950
    reactivated by the following theory command:
wenzelm@44968
   951
wenzelm@44968

   954
* Declare ext [intro] by default.  Rare INCOMPATIBILITY.
wenzelm@44968
   955
wenzelm@45088
   956
* New proof method "induction" that gives induction hypotheses the
wenzelm@45088
   957
name "IH", thus distinguishing them from further hypotheses that come
wenzelm@45088
   958
from rule induction.  The latter are still called "hyps".  Method
wenzelm@45088
   959
"induction" is a thin wrapper around "induct" and follows the same
wenzelm@45088
   960
syntax.
wenzelm@45088
   961
wenzelm@44968
   962
* Method "fastsimp" has been renamed to "fastforce", but "fastsimp" is
wenzelm@44968
   963
still available as a legacy feature for some time.
wenzelm@44968
   964
wenzelm@44968
   965
* Nitpick:
wenzelm@44968
   966
  - Added "need" and "total_consts" options.
wenzelm@44968
   967
  - Reintroduced "show_skolems" option by popular demand.
wenzelm@44968
   968
  - Renamed attribute: nitpick_def ~> nitpick_unfold.

* Sledgehammer:
wenzelm@44968
   972
  - Use quasi-sound (and efficient) translations by default.
wenzelm@44968
   973
  - Added support for the following provers: E-ToFoF, LEO-II,
wenzelm@44968
   974
    Satallax, SNARK, Waldmeister, and Z3 with TPTP syntax.
wenzelm@44968
   975
  - Automatically preplay and minimize proofs before showing them if
wenzelm@44968
   976
    this can be done within reasonable time.
wenzelm@44968
   977
  - sledgehammer available_provers ~> sledgehammer supported_provers.
wenzelm@44968
   978
    INCOMPATIBILITY.
wenzelm@44968
   979
  - Added "preplay_timeout", "slicing", "type_enc", "sound",
wenzelm@44968
   980
    "max_mono_iters", and "max_new_mono_instances" options.
wenzelm@44968
   981
  - Removed "explicit_apply" and "full_types" options as well as "Full
wenzelm@44968
   982
    Types" Proof General menu item. INCOMPATIBILITY.
wenzelm@44968
   983
wenzelm@44968
   984
* Metis:
wenzelm@44968
   985
  - Removed "metisF" -- use "metis" instead. INCOMPATIBILITY.
wenzelm@44968
   986
  - Obsoleted "metisFT" -- use "metis (full_types)" instead.
wenzelm@44968
   987
    INCOMPATIBILITY.
wenzelm@44968
   988
wenzelm@44968
   989
* Command 'try':

   990
  - Renamed 'try_methods' and added "simp:", "intro:", "dest:", and
wenzelm@44968
   991
    "elim:" options. INCOMPATIBILITY.
wenzelm@44968
   992
  - Introduced 'try' that not only runs 'try_methods' but also
wenzelm@44968
   993
    'solve_direct', 'sledgehammer', 'quickcheck', and 'nitpick'.
wenzelm@44968
   994
wenzelm@44968
   995
* Quickcheck:
wenzelm@44968
   996
  - Added "eval" option to evaluate terms for the found counterexample
wenzelm@44968
   997
    (currently only supported by the default (exhaustive) tester).
wenzelm@44968
   998
  - Added post-processing of terms to obtain readable counterexamples
wenzelm@44968
   999
    (currently only supported by the default (exhaustive) tester).
wenzelm@44968
  1000
  - New counterexample generator quickcheck[narrowing] enables
wenzelm@44968
  1001
    narrowing-based testing.  Requires the Glasgow Haskell compiler
wenzelm@44968
  1002
    with its installation location defined in the Isabelle settings
wenzelm@44968
  1003
    environment as ISABELLE_GHC.
wenzelm@44968
  1004
  - Removed quickcheck tester "SML" based on the SML code generator
wenzelm@44968
  1005
    (formly in HOL/Library).
wenzelm@44968
  1006
wenzelm@44968
  1007
* Function package: discontinued option "tailrec".  INCOMPATIBILITY,
wenzelm@44968
  1008
use 'partial_function' instead.
wenzelm@44968
  1009
wenzelm@44968
  1010
* Theory Library/Extended_Reals replaces now the positive extended
wenzelm@44968

  1012
Multivariate_Analysis/Extended_Real_Limits.
wenzelm@44968
  1013
wenzelm@44974
  1014
* Theory Library/Old_Recdef: old 'recdef' package has been moved here,
wenzelm@44974
  1015
from where it must be imported explicitly if it is really required.
wenzelm@44974
  1016
INCOMPATIBILITY.
wenzelm@44968
  1017
wenzelm@44968
  1018

  1019
been moved here.  INCOMPATIBILITY.
wenzelm@44968
  1020
wenzelm@44968
  1021
* Theory Library/Saturated provides type of numbers with saturated
wenzelm@44968
  1022
arithmetic.
wenzelm@44968
  1023
wenzelm@44968
  1024
* Theory Library/Product_Lattice defines a pointwise ordering for the
wenzelm@44968
  1025
product type 'a * 'b, and provides instance proofs for various order
wenzelm@44968
  1026
and lattice type classes.
wenzelm@44968
  1027
wenzelm@44968
  1028

wenzelm@44968
  1029
method for proving "countable" class instances for datatypes.
wenzelm@44968
  1030
wenzelm@44968
  1031
* Theory Library/Cset_Monad allows do notation for computable sets
wenzelm@44968
  1032
(cset) via the generic monad ad-hoc overloading facility.
wenzelm@44968
  1033
wenzelm@44968
  1034
* Library: Theories of common data structures are split into theories
wenzelm@44968
  1035
for implementation, an invariant-ensuring type, and connection to an
wenzelm@44968
  1036
abstract type. INCOMPATIBILITY.
wenzelm@44968
  1037
wenzelm@44968
  1038
  - RBT is split into RBT and RBT_Mapping.
wenzelm@44968

* Session Multivariate_Analysis: The euclidean_space type class now
wenzelm@44968
  1057
fixes a constant "Basis :: 'a set" consisting of the standard
wenzelm@44968
  1058
orthonormal basis for the type. Users now have the option of
wenzelm@44968
  1059
quantifying over this set instead of using the "basis" function, e.g.
wenzelm@44968
  1060
"ALL x:Basis. P x" vs "ALL i<DIM('a). P (basis i)".
wenzelm@44968
  1061
wenzelm@44968
  1062
* Session Multivariate_Analysis: Type "('a, 'b) cart" has been renamed
wenzelm@44968
  1063
to "('a, 'b) vec" (the syntax "'a ^ 'b" remains unaffected). Constants
wenzelm@44968
  1064
"Cart_nth" and "Cart_lambda" have been respectively renamed to
wenzelm@44968
  1065
"vec_nth" and "vec_lambda"; theorems mentioning those names have
wenzelm@44968
  1066
changed to match. Definition theorems for overloaded constants now use
wenzelm@44968
  1067
the standard "foo_vec_def" naming scheme. A few other theorems have
wenzelm@44968
  1068
been renamed as follows (INCOMPATIBILITY):

*** ML ***
wenzelm@41944
  1195
wenzelm@43731
  1196
* The inner syntax of sort/type/term/prop supports inlined YXML
wenzelm@43731
  1197
representations within quoted string tokens.  By encoding logical
wenzelm@43731
  1198
entities via Term_XML (in ML or Scala) concrete syntax can be
wenzelm@43731
  1199
bypassed, which is particularly useful for producing bits of text

  1200
under external program control.
wenzelm@43731
  1201
wenzelm@43565

wenzelm@42056
  1218
* Inner syntax: identifiers in parse trees of generic categories
wenzelm@42056
  1219
"logic", "aprop", "idt" etc. carry position information (disguised as
wenzelm@42056
  1220
type constraints).  Occasional INCOMPATIBILITY with non-compliant
wenzelm@42057
  1221
translations that choke on unexpected type constraints.  Positions can
wenzelm@42057
  1222
be stripped in ML translations via Syntax.strip_positions /
wenzelm@42057
  1223
Syntax.strip_positions_ast, or via the syntax constant
wenzelm@42057
  1224
"_strip_positions" within parse trees.  As last resort, positions can
wenzelm@42057
  1225
be disabled via the configuration option Syntax.positions, which is
wenzelm@42057
  1226
called "syntax_positions" in Isar attribute syntax.
wenzelm@42056

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

wenzelm@42403
  1240
* Slightly more special eq_list/eq_set, with shortcut involving
wenzelm@42403
  1241
pointer equality (assumes that eq relation is reflexive).
wenzelm@42403
  1242
wenzelm@42793
  1243
* Classical tactics use proper Proof.context instead of historic types
wenzelm@42793
  1244
claset/clasimpset.  Old-style declarations like addIs, addEs, addDs
wenzelm@42793
  1245
operate directly on Proof.context.  Raw type claset retains its use as
wenzelm@42793
  1246
snapshot of the classical context, which can be recovered via
wenzelm@42793
  1247
(put_claset HOL_cs) etc.  Type clasimpset has been discontinued.
wenzelm@42793
  1248
INCOMPATIBILITY, classical tactics and derived proof methods require

* System settings: ISABELLE_HOME_USER now includes ISABELLE_IDENTIFIER
wenzelm@41595
  1304
(and thus refers to something like $HOME/.isabelle/Isabelle2011),
wenzelm@41594
  1305
while the default heap location within that directory lacks that extra
wenzelm@41594
  1306
suffix.  This isolates multiple Isabelle installations from each
wenzelm@41594
  1307
other, avoiding problems with old settings in new versions.
wenzelm@41594
  1308
INCOMPATIBILITY, need to copy/upgrade old user settings manually.
wenzelm@41594
  1309
wenzelm@40947
  1310
* Source files are always encoded as UTF-8, instead of old-fashioned
wenzelm@40947
  1311
ISO-Latin-1.  INCOMPATIBILITY.  Isabelle LaTeX documents might require
wenzelm@40948
  1312
the following package declarations:
wenzelm@40947
  1313
wenzelm@40947
  1314
  \usepackage[utf8]{inputenc}

  1315
  \usepackage{textcomp}
wenzelm@40947
  1316
krauss@41440
  1317
* Explicit treatment of UTF-8 sequences as Isabelle symbols, such that
wenzelm@37536
  1318
a Unicode character is treated as a single symbol, not a sequence of
wenzelm@37536
  1319
non-ASCII bytes as before.  Since Isabelle/ML string literals may
wenzelm@37536
  1320
contain symbols without further backslash escapes, Unicode can now be
wenzelm@37536
  1321
used here as well.  Recall that Symbol.explode in ML provides a
wenzelm@37536
  1322
consistent view on symbols, while raw explode (or String.explode)
wenzelm@37536
  1323
merely give a byte-oriented representation.
wenzelm@37536
  1324
wenzelm@41594
  1325
* Theory loader: source files are primarily located via the master
wenzelm@41594
  1326
directory of each theory node (where the .thy file itself resides).
wenzelm@41594
  1327
The global load path is still partially available as legacy feature.
wenzelm@41594
  1328
Minor INCOMPATIBILITY due to subtle change in file lookup: use
wenzelm@41594
  1329
explicit paths, relatively to the theory.
wenzelm@38135
  1330
wenzelm@37939
  1331
* Special treatment of ML file names has been discontinued.
wenzelm@37939
  1332
Historically, optional extensions .ML or .sml were added on demand --
wenzelm@37939
  1333
at the cost of clarity of file dependencies.  Recall that Isabelle/ML
wenzelm@37939
  1334
files exclusively use the .ML extension.  Minor INCOMPATIBILTY.
wenzelm@37939
  1335
wenzelm@38980
  1336
* Various options that affect pretty printing etc. are now properly
wenzelm@38767
  1337
handled within the context via configuration options, instead of
wenzelm@40879
  1338
unsynchronized references or print modes.  There are both ML Config.T
wenzelm@40879

lists of equations to map definitions in a locale to appropriate
ballarin@41435
  1405
entities in the context of the interpretation.  The 'interpretation'
ballarin@41435

command already provided this functionality.
ballarin@41435
  1407
wenzelm@41594
  1408
* Diagnostic command 'print_dependencies' prints the locale instances
wenzelm@41594
  1409
that would be activated if the specified expression was interpreted in
wenzelm@41594
  1410
the current context.  Variant "print_dependencies!" assumes a context
wenzelm@41594
  1411
without interpretations.
ballarin@38110

foundational premises in the context, is now explicitly marked as
wenzelm@41594
  1426
legacy feature and will be discontinued soon.  Consider using "assms"

* Coercive subtyping: functions can be declared as coercions and type
wenzelm@41594
  1439
inference will add them as necessary upon input of a term.  Theory
wenzelm@41594
  1440
Complex_Main declares real :: nat => real and real :: int => real as
wenzelm@41594
  1441
coercions. A coercion function f is declared like this:
wenzelm@40939
  1442
wenzelm@40939
  1443
  declare [[coercion f]]
nipkow@40866
  1444
wenzelm@41571
  1445
To lift coercions through type constructors (e.g. from nat => real to
nipkow@40866
  1446
nat list => real list), map functions can be declared, e.g.
nipkow@40866
  1447
wenzelm@40939
  1448
  declare [[coercion_map map]]
wenzelm@40939
  1449
wenzelm@40939
  1450
Currently coercion inference is activated only in theories including
wenzelm@40939
  1451
real numbers, i.e. descendants of Complex_Main.  This is controlled by
wenzelm@41020
  1452
the configuration option "coercion_enabled", e.g. it can be enabled in
wenzelm@40939
  1453
other theories like this:
wenzelm@40939
  1454
wenzelm@40939

* Inductive package: now offers command 'inductive_simps' to
wenzelm@41594
  1471
automatically derive instantiated and simplified equations for

inductive predicates, similar to 'inductive_cases'.

wenzelm@41571
  1511
exhaustive testing by "quickcheck [exhaustive]".
haftmann@41398
  1512
haftmann@41398
  1513
* Quickcheck instantiates polymorphic types with small finite
haftmann@41398
  1514
datatypes by default. This enables a simple execution mechanism to
haftmann@41398

handle quantifiers and function equality over the finite datatypes.
haftmann@41398
  1516
wenzelm@41571

  1518
"random".  INCOMPATIBILITY.
haftmann@41398
  1519
haftmann@41398
  1520
* Quickcheck now has a configurable time limit which is set to 30
haftmann@41398
  1521
seconds by default. This can be changed by adding [timeout = n] to the
haftmann@41398
  1522
quickcheck command. The time limit for Auto Quickcheck is still set
haftmann@41398
  1523
independently.

blanchet@40059
  1548
    INCOMPATIBILITY.
blanchet@40725
  1549
  - Added support for partial quotient types.
blanchet@40725
  1550
  - Added local versions of the "Nitpick.register_xxx" functions.
blanchet@40725
  1551
  - Added "whack" option.
blanchet@40725
  1552
  - Allow registration of quotient types as codatatypes.
blanchet@40725
  1553
  - Improved "merge_type_vars" option to merge more types.
blanchet@40725
  1554
  - Removed unsound "fast_descrs" option.
blanchet@40725
  1555
  - Added custom symmetry breaking for datatypes, making it possible to reach
blanchet@40725
  1556
    higher cardinalities.
blanchet@40725
  1557
  - Prevent the expansion of too large definitions.
blanchet@39957

  1559
* Proof methods "metis" and "meson" now have configuration options
wenzelm@41571
  1560
"meson_trace", "metis_trace", and "metis_verbose" that can be enabled
wenzelm@41571
  1561
to diagnose these tools. E.g.
wenzelm@41571
  1562
wenzelm@41571
  1563
    using [[metis_trace = true]]
wenzelm@41571
  1564
haftmann@41398
  1565

  1566
manually as command 'solve_direct'.
haftmann@41398
  1567
boehmes@41601
  1568
* The default SMT solver Z3 must be enabled explicitly (due to
boehmes@41601
  1569
licensing issues) by setting the environment variable
wenzelm@41603
  1570
Z3_NON_COMMERCIAL in etc/settings of the component, for example.  For
wenzelm@41603
  1571
commercial applications, the SMT solver CVC3 is provided as fall-back;
wenzelm@41603
  1572
changing the SMT solver is done via the configuration option

* Remote SMT solvers need to be referred to by the "remote_" prefix,
wenzelm@41571
  1576
i.e. "remote_cvc3" and "remote_z3".
wenzelm@41571
  1577
wenzelm@41571
  1578
* Added basic SMT support for datatypes, records, and typedefs using
wenzelm@41571
  1579
the oracle mode (no proofs).  Direct support of pairs has been dropped
wenzelm@41571
  1580
in exchange (pass theorems fst_conv snd_conv pair_collapse to the SMT
wenzelm@41571

support for a similar behavior).  Minor INCOMPATIBILITY.
boehmes@41432
  1582

wenzelm@41594
  1602
* Simplification procedure "list_to_set_comprehension" rewrites list
wenzelm@41594
  1603
comprehensions applied to List.set to set comprehensions.  Occasional
wenzelm@41594

haftmann@41398
  1609
haftmann@41398
  1610
* Removed simplifier congruence rule of "prod_case", as has for long

  1611
been the case with "split".  INCOMPATIBILITY.
haftmann@41398
  1612
haftmann@41398
  1613
* String.literal is a type, but not a datatype.  INCOMPATIBILITY.
haftmann@41398
  1614
krauss@40388
  1615
* Removed [split_format ... and ... and ...] version of
krauss@40388
  1616
[split_format].  Potential INCOMPATIBILITY.
krauss@40388
  1617
wenzelm@41571
  1618
* Predicate "sorted" now defined inductively, with nice induction
wenzelm@41571

rules.  INCOMPATIBILITY: former sorted.simps now named sorted_simps.
haftmann@41398
  1620
haftmann@41398
  1621
* Constant "contents" renamed to "the_elem", to free the generic name
haftmann@41398
  1622
contents for other uses.  INCOMPATIBILITY.
haftmann@41398
  1623
haftmann@41398
  1624
* Renamed class eq and constant eq (for code generation) to class
haftmann@41398
  1625
equal and constant equal, plus renaming of related facts and various
haftmann@41398
  1626
tuning.  INCOMPATIBILITY.
haftmann@41398
  1627
haftmann@41398

* Dropped type classes mult_mono and mult_mono1.  INCOMPATIBILITY.
haftmann@41398
  1629
wenzelm@41571

INCOMPATIBILITY.
haftmann@41398
  1632
haftmann@41398
  1633
* Renamed theory Fset to Cset, type Fset.fset to Cset.set, in order to
haftmann@41398
  1634
avoid confusion with finite sets.  INCOMPATIBILITY.
haftmann@41398
  1635
haftmann@41398
  1636
* Abandoned locales equiv, congruent and congruent2 for equivalence
haftmann@41398
  1637
relations.  INCOMPATIBILITY: use equivI rather than equiv_intro (same
haftmann@41398
  1638

INCOMPATIBILITY.  Note that these were not supposed to be used
haftmann@41398

  1706
generation.
haftmann@41398
  1707
haftmann@41398

  1709
Haskell code.
haftmann@41398
  1710
wenzelm@41571

* Term "bij f" is now an abbreviation of "bij_betw f UNIV UNIV".  Term
wenzelm@41571
  1712
"surj f" is now an abbreviation of "range f = UNIV".  The theorems
wenzelm@41571
  1713
bij_def and surj_def are unchanged.  INCOMPATIBILITY.
haftmann@41398
  1714
haftmann@41398

"*" and "+" respectively.  INCOMPATIBILITY.
haftmann@41398
  1717
haftmann@41398

"Sum_Type.Plus" instead.
haftmann@41398
  1720
haftmann@41398
  1721
* Constant "split" has been merged with constant "prod_case"; names of
haftmann@41398
  1722
ML functions, facts etc. involving split have been retained so far,
haftmann@41398
  1723
though.  INCOMPATIBILITY.
haftmann@41398
  1724
haftmann@41398
  1725

instead.  INCOMPATIBILITY.
haftmann@41398
  1727

be euclidean_spaces.  INCOMPATIBILITY.
wenzelm@41594
  1773
wenzelm@41594
  1774
* Session Probability: introduced pextreal as positive extended real
wenzelm@41594
  1775
numbers.  Use pextreal as value for measures.  Introduce the
wenzelm@41594
  1776
Radon-Nikodym derivative, product spaces and Fubini's theorem for
wenzelm@41594
  1777
arbitrary sigma finite measures.  Introduces Lebesgue measure based on

* The domain package now runs in definitional mode by default: The
wenzelm@41571
  1803
former command 'new_domain' is now called 'domain'.  To use the domain
huffman@40621
  1804

* The new class "domain" is now the default sort.  Class "predomain"
wenzelm@41571

huffman@40621
  1814
wenzelm@41571
  1815
* The old type class "rep" has been superseded by class "domain".
huffman@40621
  1816
Accordingly, users of the definitional package must remove any
wenzelm@41571
  1817
"default_sort rep" declarations.  INCOMPATIBILITY.
huffman@40621
  1818
huffman@41401
  1819
* The domain package (definitional mode) now supports unpointed
huffman@41401
  1820
predomain argument types, as long as they are marked 'lazy'. (Strict
wenzelm@41571
  1821
arguments must be in class "domain".) For example, the following
huffman@41401
  1822
domain definition now works:
huffman@41401
  1823
huffman@41401
  1824
  domain natlist = nil | cons (lazy "nat discr") (lazy "natlist")
huffman@41401

  1827
instances for types from main HOL: bool, nat, int, char, 'a + 'b,
wenzelm@41571
  1828
'a option, and 'a list.  Additionally, it configures fixrec and the
wenzelm@41571
  1829
domain package to work with these types.  For example:
huffman@41401
  1830
huffman@41401
  1831
  fixrec isInl :: "('a + 'b) u -> tr"
huffman@41401

  domain V = VFun (lazy "V -> V") | VCon (lazy "nat") (lazy "V list")
huffman@41401
  1835
wenzelm@41571
  1836
* The "(permissive)" option of fixrec has been replaced with a
wenzelm@41571
  1837
per-equation "(unchecked)" option. See

wenzelm@41571
  1839
wenzelm@41571
  1840
* The "bifinite" class no longer fixes a constant "approx"; the class

wenzelm@41571
  1842
wenzelm@41571
  1843
* Former type "alg_defl" has been renamed to "defl".  HOLCF no longer
huffman@41287
  1844

interrupts -- intermediate handling (for cleanup etc.) needs to be

  2050
followed by re-raising of the original exception.  Another common

wenzelm@35436
  2061
* Authentic syntax for *all* logical entities (type classes, type
wenzelm@35436
  2062
constructors, term constants): provides simple and robust
wenzelm@35436
  2063
correspondence between formal entities and concrete syntax.  Within
wenzelm@35436
  2064
the parse tree / AST representations, "constants" are decorated by
wenzelm@35436
  2065
their category (class, type, const) and spelled out explicitly with
wenzelm@35436
  2066
their full internal name.
wenzelm@35436
  2067
wenzelm@35436
  2068
Substantial INCOMPATIBILITY concerning low-level syntax declarations
wenzelm@35436
  2069
and translations (translation rules and translation functions in ML).
wenzelm@35436
  2070
Some hints on upgrading:
wenzelm@35260
  2071
wenzelm@35260
  2072
  - Many existing uses of 'syntax' and 'translations' can be replaced
wenzelm@35436
  2073
    by more modern 'type_notation', 'notation' and 'abbreviation',
wenzelm@35436
  2074
    which are independent of this issue.
wenzelm@35260
  2075
wenzelm@35260
  2076
  - 'translations' require markup within the AST; the term syntax
wenzelm@35260
  2077
    provides the following special forms:
wenzelm@35260
  2078
wenzelm@35260
  2079
      CONST c   -- produces syntax version of constant c from context
wenzelm@35261
  2080
      XCONST c  -- literally c, checked as constant from context
wenzelm@35261
  2081
      c         -- literally c, if declared by 'syntax'
wenzelm@35261
  2082
wenzelm@35261
  2083
    Plain identifiers are treated as AST variables -- occasionally the
wenzelm@35261
  2084
    system indicates accidental variables via the error "rhs contains
wenzelm@35261
  2085
    extra variables".
wenzelm@35260
  2086
wenzelm@35436
  2087
    Type classes and type constructors are marked according to their
wenzelm@35436
  2088
    concrete syntax.  Some old translations rules need to be written
wenzelm@35436
  2089
    for the "type" category, using type constructor application
wenzelm@35436
  2090
    instead of pseudo-term application of the default category
wenzelm@35436
  2091
    "logic".
wenzelm@35436
  2092
wenzelm@35260
  2093
  - 'parse_translation' etc. in ML may use the following
wenzelm@35260
  2094
    antiquotations:
wenzelm@35260
  2095
wenzelm@35436
  2096
      @{class_syntax c}   -- type class c within parse tree / AST
wenzelm@35436
  2097
      @{term_syntax c}    -- type constructor c within parse tree / AST
wenzelm@35260
  2098
      @{const_syntax c}   -- ML version of "CONST c" above
wenzelm@35260
  2099
      @{syntax_const c}   -- literally c (checked wrt. 'syntax' declarations)
wenzelm@35260
  2100
wenzelm@35436
  2101
  - Literal types within 'typed_print_translations', i.e. those *not*
wenzelm@35436
  2102
    represented as pseudo-terms are represented verbatim.  Use @{class
wenzelm@35436
  2103
    c} or @{type_name c} here instead of the above syntax
wenzelm@35436
  2104
    antiquotations.
wenzelm@35436
  2105
wenzelm@35260
  2106
Note that old non-authentic syntax was based on unqualified base
wenzelm@35436
  2107
names, so all of the above "constant" names would coincide.  Recall
wenzelm@35436
  2108
that 'print_syntax' and ML_command "set Syntax.trace_ast" help to
wenzelm@35436
  2109
diagnose syntax problems.
wenzelm@35260
  2110
wenzelm@35351
  2111
* Type constructors admit general mixfix syntax, not just infix.
wenzelm@35351
  2112
wenzelm@36508
  2113
* Concrete syntax may be attached to local entities without a proof
wenzelm@36508
  2114
body, too.  This works via regular mixfix annotations for 'fix',
wenzelm@36508
  2115
'def', 'obtain' etc. or via the explicit 'write' command, which is
wenzelm@36508
  2116
similar to the 'notation' command in theory specifications.
wenzelm@36508
  2117
wenzelm@37351
  2118
* Discontinued unnamed infix syntax (legacy feature for many years) --
wenzelm@37351
  2119
need to specify constant name and syntax separately.  Internal ML
wenzelm@37351
  2120
datatype constructors have been renamed from InfixName to Infix etc.
wenzelm@37351
  2121
Minor INCOMPATIBILITY.
wenzelm@37351
  2122
wenzelm@37351
  2123
* Schematic theorem statements need to be explicitly markup as such,
wenzelm@37351
  2124
via commands 'schematic_lemma', 'schematic_theorem',
wenzelm@37351
  2125
'schematic_corollary'.  Thus the relevance of the proof is made
wenzelm@37351
  2126
syntactically clear, which impacts performance in a parallel or
wenzelm@37351
  2127
asynchronous interactive environment.  Minor INCOMPATIBILITY.
wenzelm@37351
  2128
wenzelm@35613

* Use of cumulative prems via "!" in some proof methods has been
wenzelm@37351
  2130
discontinued (old legacy feature).
wenzelm@35613
  2131
boehmes@35979
  2132
* References 'trace_simp' and 'debug_simp' have been replaced by
wenzelm@36857
  2133
configuration options stored in the context. Enabling tracing (the
wenzelm@36857
  2134
case of debugging is similar) in proofs works via
wenzelm@36857
  2135
wenzelm@36857
  2136
  using [[trace_simp = true]]
wenzelm@36857
  2137
wenzelm@36857
  2138
Tracing is then active for all invocations of the simplifier in
wenzelm@36857
  2139
subsequent goal refinement steps. Tracing may also still be enabled or
wenzelm@40780
  2140
disabled via the ProofGeneral settings menu.
boehmes@35979
  2141
wenzelm@36177
  2142
* Separate commands 'hide_class', 'hide_type', 'hide_const',
wenzelm@36177
  2143
'hide_fact' replace the former 'hide' KIND command.  Minor
wenzelm@36177
  2144
INCOMPATIBILITY.
wenzelm@36177
  2145
wenzelm@37298
  2146
* Improved parallelism of proof term normalization: usedir -p2 -q0 is
wenzelm@37298
  2147
more efficient than combinations with -q1 or -q2.

wenzelm@37351

* Proofterms record type-class reasoning explicitly, using the
wenzelm@37351
  2153
"unconstrain" operation internally.  This eliminates all sort
wenzelm@37351
  2154
constraints from a theorem and proof, introducing explicit
wenzelm@37351
  2155
OFCLASS-premises.  On the proof term level, this operation is
wenzelm@37351
  2156
automatically applied at theorem boundaries, such that closed proofs
wenzelm@37351
  2157
are always free of sort constraints.  INCOMPATIBILITY for tools that
wenzelm@37351
  2158
inspect proof terms.
haftmann@36147
  2159
wenzelm@35765
  2160
* Local theory specifications may depend on extra type variables that
wenzelm@35765
  2161
are not present in the result type -- arguments TYPE('a) :: 'a itself
wenzelm@35765
  2162
are added internally.  For example:
wenzelm@35765
  2163
wenzelm@35765
  2164
  definition unitary :: bool where "unitary = (ALL (x::'a) y. x = y)"
wenzelm@35765
  2165
wenzelm@37351
  2166
* Predicates of locales introduced by classes carry a mandatory
wenzelm@37351
  2167
"class" prefix.  INCOMPATIBILITY.
wenzelm@37351
  2168
wenzelm@37351
  2169
* Vacuous class specifications observe default sort.  INCOMPATIBILITY.
wenzelm@37351

wenzelm@37351

* Old 'axclass' command has been discontinued.  INCOMPATIBILITY, use
wenzelm@37351
  2172
'class' instead.
wenzelm@37351
  2173
wenzelm@37351
  2174
* Command 'code_reflect' allows to incorporate generated ML code into
wenzelm@37351

wenzelm@37351

wenzelm@37351

  2182
user space functionality any longer.
wenzelm@36857
  2183
wenzelm@37351
  2184
* Methods "unfold_locales" and "intro_locales" ignore non-locale
wenzelm@37351
  2185
subgoals.  This is more appropriate for interpretations with 'where'.
wenzelm@36857
  2186
INCOMPATIBILITY.
haftmann@34170
  2187
wenzelm@36356
  2188
* Command 'example_proof' opens an empty proof body.  This allows to
wenzelm@36356
  2189
experiment with Isar, without producing any persistent result.
wenzelm@36356
  2190
wenzelm@35413
  2191
* Commands 'type_notation' and 'no_type_notation' declare type syntax
wenzelm@35413

within a local theory context, with explicit checking of the
wenzelm@35413
  2193
constructors involved (in contrast to the raw 'syntax' versions).
wenzelm@35413
  2194
wenzelm@36178
  2195
* Commands 'types' and 'typedecl' now work within a local theory
wenzelm@36178
  2196
context -- without introducing dependencies on parameters or
wenzelm@36178
  2197
assumptions, which is not possible in Isabelle/Pure.
wenzelm@35681
  2198
wenzelm@36857

* Command 'typedef' now works within a local theory context -- without
wenzelm@37351
  2206
introducing dependencies on parameters or assumptions, which is not
wenzelm@37351
  2207
possible in Isabelle/Pure/HOL.  Note that the logical environment may
wenzelm@37351
  2208
contain multiple interpretations of local typedefs (with different
wenzelm@37351
  2209
non-emptiness proofs), even in a global theory context.
wenzelm@37351
  2210
wenzelm@37351
  2211
* New package for quotient types.  Commands 'quotient_type' and
wenzelm@37351
  2212
'quotient_definition' may be used for defining types and constants by
wenzelm@37351
  2213
quotient constructions.  An example is the type of integers created by
wenzelm@37351
  2214
quotienting pairs of natural numbers:
wenzelm@37380
  2215
wenzelm@37351
  2216

wenzelm@37380
  2217
    intrel :: "(nat * nat) => (nat * nat) => bool"

    "intrel (x, y) (u, v) = (x + v = u + y)"
wenzelm@37351
  2220
wenzelm@37380
  2221
  quotient_type int = "nat * nat" / intrel
wenzelm@37351

wenzelm@37351

    "0::int" is "(0::nat, 0::nat)"
wenzelm@37351
  2226
wenzelm@37351
  2227
The method "lifting" can be used to lift of theorems from the
wenzelm@37351
  2228
underlying "raw" type to the quotient type.  The example
wenzelm@37351
  2229
src/HOL/Quotient_Examples/FSet.thy includes such a quotient
wenzelm@37351
  2230
construction and provides a reasoning infrastructure for finite sets.
wenzelm@37351
  2231
wenzelm@37351
  2232
* Renamed Library/Quotient.thy to Library/Quotient_Type.thy to avoid
wenzelm@37351
  2233
clash with new theory Quotient in Main HOL.
wenzelm@37351
  2234
wenzelm@37351

wenzelm@36857
  2390
  - dropped theorem group ring_simps, use field_simps instead;

  2419
multiset order:
wenzelm@37351

wenzelm@36857
  2423
  - multiset ordering has syntax <=# and <#; partial order properties

    are provided by means of interpretation with prefix
wenzelm@36857
  2425
    multiset_order;
wenzelm@36857
  2426
  - less duplication, less historical organization of sections,
wenzelm@36857
  2427
    conversion from associations lists to multisets, rudimentary code
wenzelm@36857
  2428
    generation;

    INCOMPATIBILITY.
blanchet@36929
  2488
  - Added user's manual ("isabelle doc sledgehammer").
blanchet@36929
  2489
  - Added option syntax and "sledgehammer_params" to customize
blanchet@36929
  2490
    Sledgehammer's behavior.  See the manual for details.
blanchet@36929
  2491
  - Modified the Isar proof reconstruction code so that it produces
blanchet@36929
  2492
    direct proofs rather than proofs by contradiction.  (This feature
blanchet@36929
  2493
    is still experimental.)
blanchet@36929
  2494
  - Made Isar proof reconstruction work for SPASS, remote ATPs, and in
blanchet@36929
  2495
    full-typed mode.
blanchet@36929
  2496
  - Added support for TPTP syntax for SPASS via the "spass_tptp" ATP.

* Nitpick:
blanchet@36928
  2499
  - Added and implemented "binary_ints" and "bits" options.
blanchet@36928
  2500
  - Added "std" option and implemented support for nonstandard models.
blanchet@36928
  2501
  - Added and implemented "finitize" option to improve the precision
blanchet@36928
  2502
    of infinite datatypes based on a monotonicity analysis.
blanchet@36928
  2503
  - Added support for quotient types.
blanchet@36928
  2504
  - Added support for "specification" and "ax_specification"
blanchet@36928
  2505
    constructs.
blanchet@36928
  2506
  - Added support for local definitions (for "function" and
blanchet@36928
  2507
    "termination" proofs).
blanchet@36928
  2508
  - Added support for term postprocessors.
blanchet@36928
  2509
  - Optimized "Multiset.multiset" and "FinFun.finfun".
blanchet@36928
  2510
  - Improved efficiency of "destroy_constrs" optimization.
blanchet@36928
  2511
  - Fixed soundness bugs related to "destroy_constrs" optimization and
blanchet@36928
  2512
    record getters.
blanchet@37272
  2513
  - Fixed soundness bug related to higher-order constructors.
blanchet@37272
  2514
  - Fixed soundness bug when "full_descrs" is enabled.
blanchet@36928
  2515
  - Improved precision of set constructs.
blanchet@37260
  2516
  - Added "atoms" option.
blanchet@36928
  2517
  - Added cache to speed up repeated Kodkod invocations on the same
blanchet@36928
  2518
    problems.
blanchet@36928
  2519
  - Renamed "MiniSatJNI", "zChaffJNI", "BerkMinAlloy", and
blanchet@36928
  2520
    "SAT4JLight" to "MiniSat_JNI", "zChaff_JNI", "BerkMin_Alloy", and

blanchet@36928
  2522
  - Removed "skolemize", "uncurry", "sym_break", "flatten_prop",

  2523
    "sharing_depth", and "show_skolems" options.  INCOMPATIBILITY.

  a variable, as a shorthand for "x == t", where x is a fresh variable.
berghofe@37361
  2528
  If this is not intended, t has to be enclosed in parentheses.
berghofe@37361
  2529
  By default, the equalities generated by definitional instantiations
berghofe@37361
  2530
  are pre-simplified, which may cause parameters of inductive cases
berghofe@37361
  2531
  to disappear, or may even delete some of the inductive cases.
berghofe@37361
  2532
  Use "induct (no_simp)" instead of "induct" to restore the old
berghofe@37361
  2533
  behaviour. The (no_simp) option is also understood by the "cases"
berghofe@37361
  2534
  and "nominal_induct" methods, which now perform pre-simplification, too.

  2608
    @{const_syntax NAME}  -- syntax representation of any of the above
wenzelm@37351
  2609
wenzelm@37351
  2610
* Antiquotation @{syntax_const NAME} ensures that NAME refers to a raw
wenzelm@37351
  2611
syntax constant (cf. 'syntax' command).
wenzelm@37351
  2612
wenzelm@37351
  2613
* Antiquotation @{make_string} inlines a function to print arbitrary
wenzelm@37351
  2614
values similar to the ML toplevel.  The result is compiler dependent
wenzelm@37351
  2615
and may fall back on "?" in certain situations.
wenzelm@37351
  2616
wenzelm@37351
  2617
* Diagnostic commands 'ML_val' and 'ML_command' may refer to
wenzelm@37351
  2618
antiquotations @{Isar.state} and @{Isar.goal}.  This replaces impure
wenzelm@37351
  2619
Isar.state() and Isar.goal(), which belong to the old TTY loop and do
wenzelm@37351
  2620
not work with the asynchronous Isar document model.
wenzelm@37351
  2621
wenzelm@37351
  2622
* Configuration options now admit dynamic default values, depending on
wenzelm@37351
  2623
the context or even global references.
wenzelm@37351
  2624
wenzelm@37351
  2625
* SHA1.digest digests strings according to SHA-1 (see RFC 3174).  It
wenzelm@37351
  2626
uses an efficient external library if available (for Poly/ML).
wenzelm@37351
  2627
wenzelm@37144
  2628
* Renamed some important ML structures, while keeping the old names
wenzelm@37144
  2629
for some time as aliases within the structure Legacy:
wenzelm@37144
  2630
wenzelm@37144
  2631
  OuterKeyword  ~>  Keyword
wenzelm@37144
  2632
  OuterLex      ~>  Token
wenzelm@37144
  2633
  OuterParse    ~>  Parse
wenzelm@37144
  2634
  OuterSyntax   ~>  Outer_Syntax
wenzelm@37216
  2635
  PrintMode     ~>  Print_Mode
wenzelm@37144
  2636
  SpecParse     ~>  Parse_Spec
wenzelm@37216
  2637
  ThyInfo       ~>  Thy_Info
wenzelm@37216
  2638
  ThyLoad       ~>  Thy_Load
wenzelm@37216
  2639
  ThyOutput     ~>  Thy_Output
wenzelm@37145
  2640
  TypeInfer     ~>  Type_Infer
wenzelm@37144
  2641
wenzelm@37144
  2642
Note that "open Legacy" simplifies porting of sources, but forgetting
wenzelm@37144
  2643
to remove it again will complicate porting again in the future.
wenzelm@37144
  2644
wenzelm@37144
  2645
* Most operations that refer to a global context are named
wenzelm@37144
  2646
accordingly, e.g. Simplifier.global_context or
wenzelm@37144
  2647
ProofContext.init_global.  There are some situations where a global
wenzelm@37144
  2648
context actually works, but under normal circumstances one needs to
wenzelm@37144
  2649
pass the proper local context through the code!
wenzelm@37144
  2650
wenzelm@37144
  2651
* Discontinued old TheoryDataFun with its copy/init operation -- data
wenzelm@37144
  2652
needs to be pure.  Functor Theory_Data_PP retains the traditional
wenzelm@37144
  2653
Pretty.pp argument to merge, which is absent in the standard
wenzelm@37144
  2654
Theory_Data version.
wenzelm@36429
  2655
wenzelm@37144
  2656
* Sorts.certify_sort and derived "cert" operations for types and terms
wenzelm@37144
  2657
no longer minimize sorts.  Thus certification at the boundary of the
wenzelm@37144
  2658
inference kernel becomes invariant under addition of class relations,
wenzelm@37144
  2659
which is an important monotonicity principle.  Sorts are now minimized
wenzelm@37144
  2660
in the syntax layer only, at the boundary between the end-user and the
wenzelm@37144
  2661
system.  Subtle INCOMPATIBILITY, may have to use Sign.minimize_sort
wenzelm@37144
  2662
explicitly in rare situations.
wenzelm@37144
  2663
wenzelm@35021
  2664
* Renamed old-style Drule.standard to Drule.export_without_context, to
wenzelm@35021
  2665
emphasize that this is in no way a standard operation.
wenzelm@35021
  2666
INCOMPATIBILITY.
wenzelm@35021
  2667
wenzelm@34076
  2668
* Subgoal.FOCUS (and variants): resulting goal state is normalized as
wenzelm@34076
  2669
usual for resolution.  Rare INCOMPATIBILITY.
wenzelm@34076
  2670
wenzelm@35845
  2671
* Renamed varify/unvarify operations to varify_global/unvarify_global
wenzelm@35845
  2672
to emphasize that these only work in a global situation (which is
wenzelm@35845
  2673
quite rare).
wenzelm@35845
  2674
wenzelm@37144
  2675
* Curried take and drop in library.ML; negative length is interpreted
wenzelm@37144
  2676
as infinity (as in chop).  Subtle INCOMPATIBILITY.
wenzelm@36961
  2677
wenzelm@37351
  2678
* Proof terms: type substitutions on proof constants now use canonical
wenzelm@37351
  2679
order of type variables.  INCOMPATIBILITY for tools working with proof
wenzelm@37351
  2680
terms.
wenzelm@37351
  2681
wenzelm@37351
  2682
* Raw axioms/defs may no longer carry sort constraints, and raw defs
wenzelm@37351
  2683
may no longer carry premises.  User-level specifications are
wenzelm@37351
  2684
transformed accordingly by Thm.add_axiom/add_def.
