*** General ***
wenzelm@47967
     8
wenzelm@50126
     9
* Theorem status about oracles and unfinished/failed future proofs is
wenzelm@50126
    10
no longer printed by default, since it is incompatible with
wenzelm@50126
    11
incremental / parallel checking of the persistent document model.  ML
wenzelm@50126
    12
function Thm.peek_status may be used to inspect a snapshot of the
wenzelm@50126
    13
ongoing evaluation process.  Note that in batch mode --- notably
wenzelm@50126
    14
isabelle build --- the system ensures that future proofs of all
wenzelm@50126
    15
accessible theorems in the theory context are finished (as before).
wenzelm@50126
    16
wenzelm@49699
    17
* Configuration option show_markup controls direct inlining of markup
wenzelm@49699
    18
into the printed representation of formal entities --- notably type
wenzelm@49699
    19
and sort constraints.  This enables Prover IDE users to retrieve that
wenzelm@49699
    20
information via tooltips in the output window, for example.
wenzelm@49699
    21
wenzelm@48890
    22
* Command 'ML_file' evaluates ML text from a file directly within the
wenzelm@48890
    23
theory, without any predeclaration via 'uses' in the theory header.
wenzelm@48890
    24
wenzelm@49243
    25
* Old command 'use' command and corresponding keyword 'uses' in the
wenzelm@49243
    26
theory header are legacy features and will be discontinued soon.
wenzelm@49243
    27
Tools that load their additional source files may imitate the
wenzelm@49243
    28
'ML_file' implementation, such that the system can take care of
wenzelm@49243
    29
dependencies properly.
wenzelm@49243
    30
wenzelm@47967
    31
* Discontinued obsolete method fastsimp / tactic fast_simp_tac, which
wenzelm@47967
    32
is called fastforce / fast_force_tac already since Isabelle2011-1.
wenzelm@47967
    33
wenzelm@50110
    34
* Updated and extended "isar-ref" and "implementation" manual, reduced
wenzelm@50110
    35
remaining material in old "ref" manual.
wenzelm@48120
    36
wenzelm@49841
    37
* Improved support for auxiliary contexts indicate block structure for
wenzelm@49841
    38
specifications: nesting of "context fixes ... context assumes ..."
wenzelm@49841
    39
and "class ... context ...".
wenzelm@49841
    40
wenzelm@49869
    41
* More informative error messages for Isar proof commands involving
wenzelm@49869
    42
lazy enumerations (method applications etc.).
wenzelm@49869
    43
wenzelm@50213
    44
* Refined 'help' command to retrieve outer syntax commands according
wenzelm@50213
    45
to name patterns (with clickable results).
wenzelm@50213
    46
wenzelm@47967
    47
wenzelm@49968
    48
*** Prover IDE -- Isabelle/Scala/jEdit ***
wenzelm@49968
    49
wenzelm@49968
    50
* Parallel terminal proofs ('by') are enabled by default, likewise
wenzelm@49968
    51
proofs that are built into packages like 'datatype', 'function'.  This
wenzelm@49968
    52
allows to "run ahead" checking the theory specifications on the
wenzelm@49968
    53
surface, while the prover is still crunching on internal
wenzelm@49968
    54
justifications.  Unfinished / cancelled proofs are restarted as
wenzelm@49968
    55
required to complete full proof checking eventually.
wenzelm@49968
    56
wenzelm@49968
    57
* Improved output panel with tooltips, hyperlinks etc. based on the
wenzelm@49968
    58
same Rich_Text_Area as regular Isabelle/jEdit buffers.  Activation of
wenzelm@49968
    59
tooltips leads to some window that supports the same recursively,
wenzelm@49968
    60
which can lead to stacks of tooltips as the semantic document content
wenzelm@49968
    61
is explored.  ESCAPE closes the whole stack, individual windows may be
wenzelm@49968
    62
closed separately, or detached to become independent jEdit dockables.
wenzelm@49968
    63
wenzelm@50717
    64
* Improved support for commands that produce graph output: the text
wenzelm@50717
    65
message contains a clickable area to open a new instance of the graph
wenzelm@50717
    66
browser on demand.
wenzelm@50717
    67
wenzelm@49968
    68
* More robust incremental parsing of outer syntax (partial comments,
wenzelm@49968
    69
malformed symbols).  Changing the balance of open/close quotes and
wenzelm@49968
    70
comment delimiters works more conveniently with unfinished situations
wenzelm@49968
    71
that frequently occur in user interaction.
wenzelm@49968
    72
wenzelm@49968
    73
* More efficient painting and improved reactivity when editing large
wenzelm@49968
    74
files.  More scalable management of formal document content.
wenzelm@49968
    75
wenzelm@50505
    76
* Smarter handling of tracing messages: prover process pauses after
wenzelm@50505
    77
certain number of messages per command transaction, with some user
wenzelm@50505
    78
dialog to stop or continue.  This avoids swamping the front-end with
wenzelm@50119
    79
potentially infinite message streams.
wenzelm@49968
    80
wenzelm@49968
    81
* More plugin options and preferences, based on Isabelle/Scala.  The
wenzelm@49968
    82
jEdit plugin option panel provides access to some Isabelle/Scala
wenzelm@49968
    83
options, including tuning parameters for editor reactivity and color
wenzelm@49968
    84
schemes.
wenzelm@49968
    85
wenzelm@50184
    86
* Dockable window "Symbols" provides some editing support for Isabelle
wenzelm@50184
    87
symbols.
wenzelm@50184
    88
wenzelm@50701
    89
* Dockable window "Monitor" shows ML runtime statistics.
wenzelm@50701
    90
wenzelm@50183
    91
* Improved editing support for control styles: subscript, superscript,
wenzelm@50183
    92
bold, reset of style -- operating on single symbols or text
wenzelm@50198
    93
selections.  Cf. keyboard shortcuts C+e DOWN/UP/RIGHT/LEFT.
wenzelm@50198
    94
wenzelm@50198
    95
* Actions isabelle.increase-font-size and isabelle.decrease-font-size
wenzelm@50198
    96
adjust the main text area font size, and its derivatives for output,
wenzelm@50198
    97
tooltips etc.  Cf. keyboard shortcuts C-PLUS and C-MINUS.
wenzelm@50183
    98
wenzelm@50406
    99
* Implicit check and build dialog of the specified logic session
wenzelm@50406
   100
image.  For example, HOL, HOLCF, HOL-Nominal can be produced on
wenzelm@50406
   101
demand, without bundling big platform-dependent heap images in the
wenzelm@50406
   102
Isabelle distribution.
wenzelm@50406
   103
wenzelm@49968
   104
* Uniform Java 7 platform on Linux, Mac OS X, Windows: recent updates
wenzelm@49968
   105
from Oracle provide better multi-platform experience.  This version is
wenzelm@49968
   106
now bundled exclusively with Isabelle.
wenzelm@49968
   107
wenzelm@49968
   108
wenzelm@48205
   109
*** Pure ***
wenzelm@48205
   110
haftmann@48431
   111
* Code generation for Haskell: restrict unqualified imports from
haftmann@48431
   112
Haskell Prelude to a small set of fundamental operations.
haftmann@48431
   113
wenzelm@50646
   114
* Command 'export_code': relative file names are interpreted
wenzelm@50646
   115
relatively to master directory of current theory rather than the
wenzelm@50646
   116
rather arbitrary current working directory.  INCOMPATIBILITY.
haftmann@48371
   117
wenzelm@48205
   118
* Discontinued obsolete attribute "COMP".  Potential INCOMPATIBILITY,
wenzelm@48205
   119
use regular rule composition via "OF" / "THEN", or explicit proof
wenzelm@48205
   120
structure instead.  Note that Isabelle/ML provides a variety of
wenzelm@48205
   121
operators like COMP, INCR_COMP, COMP_INCR, which need to be applied
wenzelm@48205
   122
with some care where this is really required.
wenzelm@48205
   123
wenzelm@48792
   124
* Command 'typ' supports an additional variant with explicit sort
wenzelm@48792
   125
constraint, to infer and check the most general type conforming to a
wenzelm@48792
   126
given given sort.  Example (in HOL):
wenzelm@48792
   127
wenzelm@48792
   128
  typ "_ * _ * bool * unit" :: finite
wenzelm@48792
   129
wenzelm@50716
   130
* Command 'locale_deps' visualizes all locales and their relations as
wenzelm@50716
   131
a Hasse diagram.
wenzelm@50716
   132
wenzelm@48205
   133
bulwahn@48013
   134
*** HOL ***
bulwahn@48013
   135
wenzelm@50646
   136
* Sledgehammer:
wenzelm@50646
   137
wenzelm@50646
   138
  - Added MaSh relevance filter based on machine-learning; see the
wenzelm@50646
   139
    Sledgehammer manual for details.
wenzelm@50646
   140
  - Polished Isar proofs generated with "isar_proofs" option.
wenzelm@50646
   141
  - Rationalized type encodings ("type_enc" option).
blanchet@50720
   142
  - Renamed "kill_provers" subcommand to "kill_all".
wenzelm@50646
   143
  - Renamed options:
wenzelm@50646
   144
      isar_proof ~> isar_proofs
wenzelm@50646
   145
      isar_shrink_factor ~> isar_shrink
wenzelm@50646
   146
      max_relevant ~> max_facts
wenzelm@50646
   147
      relevance_thresholds ~> fact_thresholds
wenzelm@50646
   148
wenzelm@50646
   149
* Quickcheck: added an optimisation for equality premises.  It is
wenzelm@50646
   150
switched on by default, and can be switched off by setting the
wenzelm@50646
   151
configuration quickcheck_optimise_equality to false.
wenzelm@50646
   152
wenzelm@50646
   153
* Simproc "finite_Collect" rewrites set comprehensions into pointfree
wenzelm@50646
   154
expressions.
wenzelm@50646
   155
wenzelm@50646
   156
* Preprocessing of the code generator rewrites set comprehensions into
wenzelm@50646
   157
pointfree expressions.
wenzelm@50646
   158
wenzelm@50646
   159
* The SMT solver Z3 has now by default a restricted set of directly
wenzelm@50646
   160
supported features. For the full set of features (div/mod, nonlinear
wenzelm@50646
   161
arithmetic, datatypes/records) with potential proof reconstruction
wenzelm@50646
   162
failures, enable the configuration option "z3_with_extensions".  Minor
wenzelm@50646
   163
INCOMPATIBILITY.
haftmann@49948
   164
wenzelm@49836
   165
* Simplified 'typedef' specifications: historical options for implicit
wenzelm@49836
   166
set definition and alternative name have been discontinued.  The
wenzelm@49836
   167
former behavior of "typedef (open) t = A" is now the default, but
wenzelm@49836
   168
written just "typedef t = A".  INCOMPATIBILITY, need to adapt theories
wenzelm@49836
   169
accordingly.
wenzelm@49836
   170
wenzelm@50646
   171
* Removed constant "chars"; prefer "Enum.enum" on type "char"
wenzelm@50646
   172
directly.  INCOMPATIBILITY.
wenzelm@50646
   173
wenzelm@50646
   174
* Moved operation product, sublists and n_lists from theory Enum to
wenzelm@50646
   175
List.  INCOMPATIBILITY.
haftmann@49822
   176
haftmann@49739
   177
* Theorem UN_o generalized to SUP_comp.  INCOMPATIBILITY.
haftmann@49739
   178
haftmann@49738
   179
* Class "comm_monoid_diff" formalises properties of bounded
haftmann@49388
   180
subtraction, with natural numbers and multisets as typical instances.
haftmann@49388
   181
wenzelm@50646
   182
* Added combinator "Option.these" with type "'a option set => 'a set".
wenzelm@50646
   183
wenzelm@50646
   184
* Theory "Transitive_Closure": renamed lemmas
wenzelm@50646
   185
wenzelm@50646
   186
  reflcl_tranclp -> reflclp_tranclp
wenzelm@50646
   187
  rtranclp_reflcl -> rtranclp_reflclp
wenzelm@50646
   188
wenzelm@50646
   189
INCOMPATIBILITY.
wenzelm@50646
   190
wenzelm@50646
   191
* Theory "Rings": renamed lemmas (in class semiring)
wenzelm@50646
   192
wenzelm@50646
   193
  left_distrib ~> distrib_right
wenzelm@50646
   194
  right_distrib ~> distrib_left
wenzelm@50646
   195
wenzelm@50646
   196
INCOMPATIBILITY.
wenzelm@50646
   197
wenzelm@50646
   198
* Generalized the definition of limits:
wenzelm@50646
   199
wenzelm@50646
   200
  - Introduced the predicate filterlim (LIM x F. f x :> G) which
wenzelm@50646
   201
    expresses that when the input values x converge to F then the
wenzelm@50646
   202
    output f x converges to G.
wenzelm@50646
   203
wenzelm@50646
   204
  - Added filters for convergence to positive (at_top) and negative
wenzelm@50646
   205
    infinity (at_bot).
wenzelm@50646
   206
wenzelm@50646
   207
  - Moved infinity in the norm (at_infinity) from
wenzelm@50646
   208
    Multivariate_Analysis to Complex_Main.
wenzelm@50646
   209
wenzelm@50646
   210
  - Removed real_tendsto_inf, it is superseded by "LIM x F. f x :>
wenzelm@50646
   211
    at_top".
wenzelm@50646
   212
wenzelm@50646
   213
INCOMPATIBILITY.
wenzelm@50646
   214
wenzelm@50646
   215
* Theory "Library/Option_ord" provides instantiation of option type to
wenzelm@50646
   216
lattice type classes.
wenzelm@50646
   217
wenzelm@50646
   218
* Theory "Library/Multiset": renamed
wenzelm@50646
   219
wenzelm@50646
   220
    constant fold_mset ~> Multiset.fold
wenzelm@50646
   221
    fact fold_mset_commute ~> fold_mset_comm
wenzelm@50646
   222
wenzelm@50646
   223
INCOMPATIBILITY.
wenzelm@50646
   224
wenzelm@50646
   225
* Renamed theory Library/List_Prefix to Library/Sublist, with related
wenzelm@50646
   226
changes as follows.
wenzelm@50646
   227
wenzelm@50646
   228
  - Renamed constants (and related lemmas)
Christian@49145
   229
Christian@49145
   230
      prefix ~> prefixeq
Christian@49145
   231
      strict_prefix ~> prefix
Christian@49145
   232
wenzelm@50646
   233
  - Replaced constant "postfix" by "suffixeq" with swapped argument
wenzelm@50646
   234
    order (i.e., "postfix xs ys" is now "suffixeq ys xs") and dropped
wenzelm@50646
   235
    old infix syntax "xs >>= ys"; use "suffixeq ys xs" instead.
wenzelm@50646
   236
    Renamed lemmas accordingly.
wenzelm@50646
   237
wenzelm@50646
   238
  - Added constant "list_hembeq" for homeomorphic embedding on
wenzelm@50646
   239
    lists. Added abbreviation "sublisteq" for special case
wenzelm@50646
   240
    "list_hembeq (op =)".
wenzelm@50646
   241
wenzelm@50646
   242
  - Theory Library/Sublist no longer provides "order" and "bot" type
wenzelm@50646
   243
    class instances for the prefix order (merely corresponding locale
wenzelm@50646
   244
    interpretations). The type class instances are now in theory
wenzelm@50646
   245
    Library/Prefix_Order.
wenzelm@50646
   246
wenzelm@50646
   247
  - The sublist relation of theory Library/Sublist_Order is now based
wenzelm@50646
   248
    on "Sublist.sublisteq".  Renamed lemmas accordingly:
Christian@50516
   249
Christian@50516
   250
      le_list_append_le_same_iff ~> Sublist.sublisteq_append_le_same_iff
Christian@50516
   251
      le_list_append_mono ~> Sublist.list_hembeq_append_mono
Christian@50516
   252
      le_list_below_empty ~> Sublist.list_hembeq_Nil, Sublist.list_hembeq_Nil2
Christian@50516
   253
      le_list_Cons_EX ~> Sublist.list_hembeq_ConsD
Christian@50516
   254
      le_list_drop_Cons2 ~> Sublist.sublisteq_Cons2'
Christian@50516
   255
      le_list_drop_Cons_neq ~> Sublist.sublisteq_Cons2_neq
Christian@50516
   256
      le_list_drop_Cons ~> Sublist.sublisteq_Cons'
Christian@50516
   257
      le_list_drop_many ~> Sublist.sublisteq_drop_many
Christian@50516
   258
      le_list_filter_left ~> Sublist.sublisteq_filter_left
Christian@50516
   259
      le_list_rev_drop_many ~> Sublist.sublisteq_rev_drop_many
Christian@50516
   260
      le_list_rev_take_iff ~> Sublist.sublisteq_append
Christian@50516
   261
      le_list_same_length ~> Sublist.sublisteq_same_length
Christian@50516
   262
      le_list_take_many_iff ~> Sublist.sublisteq_append'
Christian@49145
   263
      less_eq_list.drop ~> less_eq_list_drop
Christian@49145
   264
      less_eq_list.induct ~> less_eq_list_induct
Christian@50516
   265
      not_le_list_length ~> Sublist.not_sublisteq_length
Christian@49145
   266
wenzelm@50646
   267
INCOMPATIBILITY.
wenzelm@50646
   268
wenzelm@50646
   269
wenzelm@50646
   270
* New theory Library/Countable_Set.
wenzelm@50646
   271
wenzelm@50646
   272
* Theory Library/Debug and Library/Parallel provide debugging and
wenzelm@50646
   273

* Theory Library/FuncSet: Extended support for Pi and extensional and
wenzelm@50646
   276
introduce the extensional dependent function space "PiE". Replaced
wenzelm@50646
   277
extensional_funcset by an abbreviation, and renamed lemmas from
wenzelm@50646

wenzelm@50646
   297
* Theory Library/Phantom: generic phantom type to make a type
wenzelm@50646
   298
parameter appear in a constant's type.  This alternative to adding
wenzelm@50646
   299
TYPE('a) as another parameter avoids unnecessary closures in generated
wenzelm@50646
   300
code.
wenzelm@50646

* Theory Library/RBT_Impl: efficient construction of red-black trees
wenzelm@50646
   303
from sorted associative lists. Merging two trees with rbt_union may
wenzelm@50646
   304
return a structurally different tree than before.  Potential
wenzelm@50646
   305
INCOMPATIBILITY.

   318
"SUM i : Basis. f i * r i".
wenzelm@50646
   319
wenzelm@50646

  With this change the following constants are also changed or removed:

* HOL/Probability:
wenzelm@50646
   345
wenzelm@50646
   346
  - Added simproc "measurable" to automatically prove measurability.
wenzelm@50646
   347
wenzelm@50646
   348
  - Added induction rules for sigma sets with disjoint union
wenzelm@50646
   349
    (sigma_sets_induct_disjoint) and for Borel-measurable functions
wenzelm@50646
   350
    (borel_measurable_induct).
wenzelm@50646
   351
wenzelm@50646
   352
  - Added the Daniell-Kolmogorov theorem (the existence the limit of a

*** Document preparation ***
wenzelm@48206
   364
wenzelm@50646
   365
* Dropped legacy antiquotations "term_style" and "thm_style", since
wenzelm@50646
   366
styles may be given as arguments to "term" and "thm" already.
wenzelm@50646
   367
Discontinued legacy styles "prem1" .. "prem19".
wenzelm@50646
   368
wenzelm@50646
   369
* Default LaTeX rendering for \<euro> is now based on eurosym package,
wenzelm@50646
   370
instead of slightly exotic babel/greek.
wenzelm@48206
   371
wenzelm@48616
   372
* Document variant NAME may use different LaTeX entry point
wenzelm@48616
   373
document/root_NAME.tex if that file exists, instead of the common
wenzelm@48616
   374
document/root.tex.
wenzelm@48616
   375
wenzelm@48657
   376
* Simplified custom document/build script, instead of old-style
wenzelm@48657

*** ML ***
wenzelm@48992
   381
wenzelm@50646
   382
* The default limit for maximum number of worker threads is now 8,
wenzelm@50646
   383
instead of 4, in correspondence to capabilities of contemporary
wenzelm@50646
   384
hardware and Poly/ML runtime system.
wenzelm@50646
   385
wenzelm@49869
   386
* Type Seq.results and related operations support embedded error
wenzelm@49869
   387
messages within lazy enumerations, and thus allow to provide
wenzelm@49869
   388
informative errors in the absence of any usable results.
wenzelm@49869
   389
wenzelm@48992
   390
* Renamed Position.str_of to Position.here to emphasize that this is a
wenzelm@48992
   391
formal device to inline positions into message text, but not
wenzelm@48992
   392
necessarily printing visible text.

*** System ***
wenzelm@48206
   396
wenzelm@48585
   397
* Advanced support for Isabelle sessions and build management, see
wenzelm@48585
   398
"system" manual for the chapter of that name, especially the "isabelle
wenzelm@48736
   399
build" tool and its examples.  INCOMPATIBILITY, isabelle usedir /
wenzelm@48736
   400
mkdir / make are rendered obsolete.
wenzelm@48736
   401
wenzelm@48736
   402
* Discontinued obsolete "isabelle makeall".
wenzelm@48585
   403
wenzelm@48722
   404
* Discontinued obsolete IsaMakefile and ROOT.ML files from the
wenzelm@48722
   405
Isabelle distribution, except for rudimentary src/HOL/IsaMakefile that
wenzelm@48722
   406
provides some traditional targets that invoke "isabelle build".  Note
wenzelm@48722
   407
that this is inefficient!  Applications of Isabelle/HOL involving
wenzelm@48722
   408
"isabelle make" should be upgraded to use "isabelle build" directly.
wenzelm@48722
   409
wenzelm@48586
   410
* Discontinued obsolete Isabelle/build script, it is superseded by the
wenzelm@48586
   411
regular isabelle build tool.  For example:
wenzelm@48586
   412
wenzelm@48586
   413
  isabelle build -s -b HOLCF
wenzelm@48586
   414
wenzelm@48693
   415
* The "isabelle options" tool prints Isabelle system options, as
wenzelm@48693
   416
required for "isabelle build", for example.
wenzelm@48693
   417
wenzelm@48683
   418
* The "isabelle mkroot" tool prepares session root directories for use
wenzelm@48683
   419
with "isabelle build", similar to former "isabelle mkdir" for
wenzelm@48683
   420
"isabelle usedir".
wenzelm@48683
   421
wenzelm@50646
   422
* The "isabelle logo" tool produces EPS and PDF format simultaneously.
wenzelm@50646
   423
Minor INCOMPATIBILITY in command-line options.
wenzelm@50646
   424
wenzelm@50646
   425
* The "isabelle install" tool has now a simpler command-line.  Minor
wenzelm@50646
   426
INCOMPATIBILITY.
wenzelm@50646
   427
wenzelm@48844
   428
* The "isabelle components" tool helps to resolve add-on components
wenzelm@48844
   429
that are not bundled, or referenced from a bare-bones repository
wenzelm@48844
   430
version of Isabelle.
wenzelm@48844
   431
wenzelm@50646
   432
* Settings variable ISABELLE_PLATFORM_FAMILY refers to the general
wenzelm@50646
   433
platform family: "linux", "macos", "windows".
wenzelm@50646
   434
wenzelm@50646
   435
* The ML system is configured as regular component, and no longer
wenzelm@50646
   436
picked up from some surrounding directory.  Potential INCOMPATIBILITY
wenzelm@50646
   437
for home-made settings.
wenzelm@50132
   438
wenzelm@50701
   439
* Improved ML runtime statistics (heap, threads, future tasks etc.).
wenzelm@50701
   440
wenzelm@48206
   441
* Discontinued support for Poly/ML 5.2.1, which was the last version
wenzelm@48206
   442
without exception positions and advanced ML compiler/toplevel
wenzelm@48206
   443
configuration.
wenzelm@48206
   444
wenzelm@48574
   445
* Discontinued special treatment of Proof General -- no longer guess
wenzelm@48574
   446
PROOFGENERAL_HOME based on accidental file-system layout.  Minor
wenzelm@48574
   447
INCOMPATIBILITY: provide PROOFGENERAL_HOME and PROOFGENERAL_OPTIONS
wenzelm@48574
   448
settings manually, or use a Proof General version that has been
wenzelm@48574
   449
bundled as Isabelle component.

wenzelm@45593
   456
*** General ***
wenzelm@45593
   457
wenzelm@45614
   458
* Prover IDE (PIDE) improvements:
wenzelm@45614
   459
wenzelm@47585
   460
  - more robust Sledgehammer integration (as before the sledgehammer
wenzelm@47806
   461
    command-line needs to be typed into the source buffer)
wenzelm@45614
   462
  - markup for bound variables
wenzelm@47806
   463
  - markup for types of term variables (displayed as tooltips)
wenzelm@46956
   464
  - support for user-defined Isar commands within the running session
wenzelm@47158
   465
  - improved support for Unicode outside original 16bit range
wenzelm@47158
   466
    e.g. glyph for \<A> (thanks to jEdit 4.5.1)
wenzelm@45614
   467
wenzelm@47806
   468
* Forward declaration of outer syntax keywords within the theory
wenzelm@47806
   469
header -- minor INCOMPATIBILITY for user-defined commands.  Allow new
wenzelm@47806
   470
commands to be used in the same theory where defined.
wenzelm@46485
   471
wenzelm@47482
   472
* Auxiliary contexts indicate block structure for specifications with
wenzelm@47482
   473
additional parameters and assumptions.  Such unnamed contexts may be
wenzelm@47482
   474
nested within other targets, like 'theory', 'locale', 'class',
wenzelm@47482
   475
'instantiation' etc.  Results from the local context are generalized
wenzelm@47482
   476
accordingly and applied to the enclosing target context.  Example:
wenzelm@47482
   477
wenzelm@47482
   478
  context
wenzelm@47482
   479
    fixes x y z :: 'a
wenzelm@47482
   480
    assumes xy: "x = y" and yz: "y = z"
wenzelm@47482
   481
  begin
wenzelm@47482
   482
wenzelm@47482
   483
  lemma my_trans: "x = z" using xy yz by simp
wenzelm@47482
   484
wenzelm@47482
   485
  end
wenzelm@47482
   486
wenzelm@47482
   487
  thm my_trans
wenzelm@47482
   488
wenzelm@47482
   489
The most basic application is to factor-out context elements of
wenzelm@47482
   490
several fixes/assumes/shows theorem statements, e.g. see
wenzelm@47482
   491
~~/src/HOL/Isar_Examples/Group_Context.thy
wenzelm@47482
   492
wenzelm@47482
   493
Any other local theory specification element works within the "context
wenzelm@47482
   494
... begin ... end" block as well.
wenzelm@47482
   495
wenzelm@47484
   496
* Bundled declarations associate attributed fact expressions with a
wenzelm@47484
   497
given name in the context.  These may be later included in other
wenzelm@47484
   498
contexts.  This allows to manage context extensions casually, without
wenzelm@47855
   499
the logical dependencies of locales and locale interpretation.  See
wenzelm@47855
   500
commands 'bundle', 'include', 'including' etc. in the isar-ref manual.
wenzelm@47484
   501
wenzelm@47829
   502
* Commands 'lemmas' and 'theorems' allow local variables using 'for'
wenzelm@47829
   503
declaration, and results are standardized before being stored.  Thus
wenzelm@47829
   504
old-style "standard" after instantiation or composition of facts
wenzelm@47829
   505
becomes obsolete.  Minor INCOMPATIBILITY, due to potential change of
wenzelm@47829
   506
indices of schematic variables.
wenzelm@47829
   507
wenzelm@47829
   508
* Rule attributes in local theory declarations (e.g. locale or class)
wenzelm@47829
   509
are now statically evaluated: the resulting theorem is stored instead
wenzelm@47829
   510
of the original expression.  INCOMPATIBILITY in rare situations, where
wenzelm@47829
   511
the historic accident of dynamic re-evaluation in interpretations
wenzelm@47829
   512
etc. was exploited.
wenzelm@47829
   513
wenzelm@47829
   514
* New tutorial "Programming and Proving in Isabelle/HOL"
wenzelm@47829
   515
("prog-prove").  It completely supersedes "A Tutorial Introduction to
wenzelm@47829
   516
Structured Isar Proofs" ("isar-overview"), which has been removed.  It
wenzelm@47829
   517
also supersedes "Isabelle/HOL, A Proof Assistant for Higher-Order
wenzelm@47829
   518
Logic" as the recommended beginners tutorial, but does not cover all
wenzelm@47829
   519
of the material of that old tutorial.
wenzelm@47829
   520
wenzelm@47829
   521
* Updated and extended reference manuals: "isar-ref",
wenzelm@47829
   522
"implementation", "system"; reduced remaining material in old "ref"
wenzelm@47829
   523
manual.
wenzelm@47829
   524
wenzelm@47829
   525
wenzelm@47829
   526
*** Pure ***
wenzelm@47829
   527
wenzelm@46976
   528
* Command 'definition' no longer exports the foundational "raw_def"
wenzelm@46976
   529
into the user context.  Minor INCOMPATIBILITY, may use the regular
wenzelm@46976
   530
"def" result with attribute "abs_def" to imitate the old version.
wenzelm@46976
   531
wenzelm@47855
   532
* Attribute "abs_def" turns an equation of the form "f x y == t" into
wenzelm@47855
   533
"f == %x y. t", which ensures that "simp" or "unfold" steps always
wenzelm@47855
   534
expand it.  This also works for object-logic equality.  (Formerly
wenzelm@47855
   535
undocumented feature.)
wenzelm@47855
   536
wenzelm@47856
   537
* Sort constraints are now propagated in simultaneous statements, just
wenzelm@47856
   538
like type constraints.  INCOMPATIBILITY in rare situations, where
wenzelm@47856
   539
distinct sorts used to be assigned accidentally.  For example:
wenzelm@47856
   540
wenzelm@47856
   541
  lemma "P (x::'a::foo)" and "Q (y::'a::bar)"  -- "now illegal"
wenzelm@47856
   542
wenzelm@47856
   543
  lemma "P (x::'a)" and "Q (y::'a::bar)"
wenzelm@47856
   544
    -- "now uniform 'a::bar instead of default sort for first occurrence (!)"
wenzelm@47856
   545
wenzelm@47856
   546
* Rule composition via attribute "OF" (or ML functions OF/MRS) is more
wenzelm@47856
   547
tolerant against multiple unifiers, as long as the final result is
wenzelm@47856
   548
unique.  (As before, rules are composed in canonical right-to-left
wenzelm@47856
   549
order to accommodate newly introduced premises.)
wenzelm@47856

wenzelm@47806
   551
* Renamed some inner syntax categories:
wenzelm@47806
   552
wenzelm@47806
   553
    num ~> num_token
wenzelm@47806
   554
    xnum ~> xnum_token
wenzelm@47806
   555
    xstr ~> str_token
wenzelm@47806
   556
wenzelm@47806
   557
Minor INCOMPATIBILITY.  Note that in practice "num_const" or
wenzelm@47806
   558
"num_position" etc. are mainly used instead (which also include
wenzelm@47806
   559
position information via constraints).
wenzelm@47806
   560
wenzelm@47829
   561
* Simplified configuration options for syntax ambiguity: see
wenzelm@47829
   562
"syntax_ambiguity_warning" and "syntax_ambiguity_limit" in isar-ref
wenzelm@47829
   563
manual.  Minor INCOMPATIBILITY.
wenzelm@47829
   564
wenzelm@47856
   565
* Discontinued configuration option "syntax_positions": atomic terms
wenzelm@47856
   566
in parse trees are always annotated by position constraints.
wenzelm@45134
   567
wenzelm@47464
   568
* Old code generator for SML and its commands 'code_module',
wenzelm@45383
   569
'code_library', 'consts_code', 'types_code' have been discontinued.
haftmann@46028
   570
Use commands of the generic code generator instead.  INCOMPATIBILITY.
wenzelm@45383
   571
wenzelm@47464
   572
* Redundant attribute "code_inline" has been discontinued. Use
wenzelm@47464
   573
"code_unfold" instead.  INCOMPATIBILITY.
wenzelm@47464
   574
wenzelm@47464
   575
* Dropped attribute "code_unfold_post" in favor of the its dual
wenzelm@47464
   576
"code_abbrev", which yields a common pattern in definitions like
haftmann@46028
   577
haftmann@46028
   578
  definition [code_abbrev]: "f = t"
haftmann@46028
   579
haftmann@46028
   580
INCOMPATIBILITY.
wenzelm@45383
   581
wenzelm@47856
   582
* Obsolete 'types' command has been discontinued.  Use 'type_synonym'
wenzelm@47856
   583
instead.  INCOMPATIBILITY.
wenzelm@47856
   584
wenzelm@47856
   585
* Discontinued old "prems" fact, which used to refer to the accidental
wenzelm@47856
   586
collection of foundational premises in the context (already marked as
wenzelm@47856
   587
legacy since Isabelle2011).

* Type 'a set is now a proper type constructor (just as before
wenzelm@47464
   593
Isabelle2008).  Definitions mem_def and Collect_def have disappeared.
wenzelm@47464
   594
Non-trivial INCOMPATIBILITY.  For developments keeping predicates and
wenzelm@47855
   595
sets separate, it is often sufficient to rephrase some set S that has
wenzelm@47855
   596
been accidentally used as predicates by "%x. x : S", and some
wenzelm@47855
   597
predicate P that has been accidentally used as set by "{x. P x}".
wenzelm@47855
   598
Corresponding proofs in a first step should be pruned from any
wenzelm@47855
   599
tinkering with former theorems mem_def and Collect_def as far as
wenzelm@47855
   600
possible.
wenzelm@47855
   601
wenzelm@47855
   602
For developments which deliberately mix predicates and sets, a
wenzelm@47464
   603
planning step is necessary to determine what should become a predicate
wenzelm@47464
   604
and what a set.  It can be helpful to carry out that step in
wenzelm@47464
   605
Isabelle2011-1 before jumping right into the current release.
wenzelm@47464
   606
wenzelm@47855
   607
* Code generation by default implements sets as container type rather
wenzelm@47855
   608
than predicates.  INCOMPATIBILITY.
wenzelm@47855
   609
wenzelm@47855
   610
* New type synonym 'a rel = ('a * 'a) set
wenzelm@47855
   611
wenzelm@47464
   612
* The representation of numerals has changed.  Datatype "num"
wenzelm@47464
   613
represents strictly positive binary numerals, along with functions
wenzelm@47464
   614
"numeral :: num => 'a" and "neg_numeral :: num => 'a" to represent
wenzelm@47855
   615
positive and negated numeric literals, respectively.  See also
wenzelm@47855
   616
definitions in ~~/src/HOL/Num.thy.  Potential INCOMPATIBILITY, some
wenzelm@47855
   617
user theories may require adaptations as follows:
huffman@47108
   618
huffman@47108
   619
  - Theorems with number_ring or number_semiring constraints: These
huffman@47108
   620
    classes are gone; use comm_ring_1 or comm_semiring_1 instead.
huffman@47108
   621
huffman@47108
   622
  - Theories defining numeric types: Remove number, number_semiring,
huffman@47108
   623
    and number_ring instances. Defer all theorems about numerals until
huffman@47108
   624
    after classes one and semigroup_add have been instantiated.
huffman@47108
   625
huffman@47108
   626
  - Numeral-only simp rules: Replace each rule having a "number_of v"
huffman@47108
   627
    pattern with two copies, one for numeral and one for neg_numeral.
huffman@47108
   628
huffman@47108
   629
  - Theorems about subclasses of semiring_1 or ring_1: These classes
huffman@47108
   630
    automatically support numerals now, so more simp rules and
huffman@47108
   631
    simprocs may now apply within the proof.
huffman@47108
   632
huffman@47108
   633
  - Definitions and theorems using old constructors Pls/Min/Bit0/Bit1:
huffman@47108
   634
    Redefine using other integer operations.
huffman@47108
   635
wenzelm@47855
   636
* Transfer: New package intended to generalize the existing
wenzelm@47855
   637
"descending" method and related theorem attributes from the Quotient
wenzelm@47855
   638
package.  (Not all functionality is implemented yet, but future
wenzelm@47855
   639
development will focus on Transfer as an eventual replacement for the
wenzelm@47855
   640
corresponding parts of the Quotient package.)
wenzelm@47809
   641
wenzelm@47809
   642
  - transfer_rule attribute: Maintains a collection of transfer rules,
wenzelm@47809
   643
    which relate constants at two different types. Transfer rules may
wenzelm@47809
   644
    relate different type instances of the same polymorphic constant,
wenzelm@47809
   645
    or they may relate an operation on a raw type to a corresponding
wenzelm@47809
   646
    operation on an abstract type (quotient or subtype). For example:
wenzelm@47809
   647
wenzelm@47809
   648
    ((A ===> B) ===> list_all2 A ===> list_all2 B) map map
wenzelm@47809
   649
    (cr_int ===> cr_int ===> cr_int) (%(x,y) (u,v). (x+u, y+v)) plus_int
wenzelm@47809
   650
wenzelm@47809
   651
  - transfer method: Replaces a subgoal on abstract types with an
wenzelm@47809
   652
    equivalent subgoal on the corresponding raw types. Constants are
wenzelm@47809
   653
    replaced with corresponding ones according to the transfer rules.
wenzelm@47809
   654
    Goals are generalized over all free variables by default; this is
huffman@47851
   655
    necessary for variables whose types change, but can be overridden
wenzelm@47855
   656
    for specific variables with e.g. "transfer fixing: x y z".  The
wenzelm@47809
   657
    variant transfer' method allows replacing a subgoal with one that
wenzelm@47809
   658
    is logically stronger (rather than equivalent).
wenzelm@47809
   659
wenzelm@47809
   660
  - relator_eq attribute: Collects identity laws for relators of
wenzelm@47809
   661
    various type constructors, e.g. "list_all2 (op =) = (op =)".  The
wenzelm@47809
   662
    transfer method uses these lemmas to infer transfer rules for
wenzelm@47809
   663
    non-polymorphic constants on the fly.
wenzelm@47809
   664
wenzelm@47809
   665
  - transfer_prover method: Assists with proving a transfer rule for a
wenzelm@47809
   666
    new constant, provided the constant is defined in terms of other
wenzelm@47809
   667
    constants that already have transfer rules. It should be applied
wenzelm@47809
   668
    after unfolding the constant definitions.

wenzelm@47809

huffman@47851
   673
* Lifting: New package intended to generalize the quotient_definition
huffman@47851
   674
facility of the Quotient package; designed to work with Transfer.
wenzelm@47809
   675
wenzelm@47809
   676
  - lift_definition command: Defines operations on an abstract type in
wenzelm@47809
   677
    terms of a corresponding operation on a representation
wenzelm@47809
   678
    type.  Example syntax:
wenzelm@47809
   679
wenzelm@47809
   680
    lift_definition dlist_insert :: "'a => 'a dlist => 'a dlist"
wenzelm@47809
   681
      is List.insert
wenzelm@47809
   682
wenzelm@47809
   683
    Users must discharge a respectfulness proof obligation when each
wenzelm@47809
   684
    constant is defined. (For a type copy, i.e. a typedef with UNIV,
wenzelm@47809
   685
    the proof is discharged automatically.) The obligation is
wenzelm@47809
   686
    presented in a user-friendly, readable form; a respectfulness
wenzelm@47809
   687
    theorem in the standard format and a transfer rule are generated
wenzelm@47809
   688
    by the package.
wenzelm@47809
   689
wenzelm@47809
   690
  - Integration with code_abstype: For typedefs (e.g. subtypes
wenzelm@47809
   691
    corresponding to a datatype invariant, such as dlist),
wenzelm@47809
   692
    lift_definition generates a code certificate theorem and sets up
wenzelm@47809
   693
    code generation for each constant.
wenzelm@47809
   694
wenzelm@47809
   695
  - setup_lifting command: Sets up the Lifting package to work with a
wenzelm@47809
   696
    user-defined type. The user must provide either a quotient theorem
wenzelm@47809
   697
    or a type_definition theorem.  The package configures transfer
wenzelm@47809
   698
    rules for equality and quantifiers on the type, and sets up the
wenzelm@47809
   699
    lift_definition command to work with the type.
wenzelm@47809
   700
wenzelm@47809
   701
  - Usage examples: See Quotient_Examples/Lift_DList.thy,
huffman@47851
   702
    Quotient_Examples/Lift_RBT.thy, Quotient_Examples/Lift_FSet.thy,
huffman@47851
   703
    Word/Word.thy and Library/Float.thy.
wenzelm@47809
   704
wenzelm@47809
   705
* Quotient package:
wenzelm@47809
   706
wenzelm@47809
   707
  - The 'quotient_type' command now supports a 'morphisms' option with
wenzelm@47809
   708
    rep and abs functions, similar to typedef.
wenzelm@47809
   709
wenzelm@47809
   710
  - 'quotient_type' sets up new types to work with the Lifting and
wenzelm@47809
   711
    Transfer packages, as with 'setup_lifting'.
wenzelm@47809
   712
wenzelm@47809
   713
  - The 'quotient_definition' command now requires the user to prove a
wenzelm@47809
   714
    respectfulness property at the point where the constant is
wenzelm@47809
   715
    defined, similar to lift_definition; INCOMPATIBILITY.
wenzelm@47809
   716
wenzelm@47809
   717
  - Renamed predicate 'Quotient' to 'Quotient3', and renamed theorems
wenzelm@47809
   718
    accordingly, INCOMPATIBILITY.
wenzelm@47809
   719
wenzelm@47809
   720
* New diagnostic command 'find_unused_assms' to find potentially
wenzelm@47809
   721
superfluous assumptions in theorems using Quickcheck.
wenzelm@47809
   722
wenzelm@47809
   723
* Quickcheck:
wenzelm@47809
   724
wenzelm@47809
   725
  - Quickcheck returns variable assignments as counterexamples, which
wenzelm@47809
   726
    allows to reveal the underspecification of functions under test.
wenzelm@47809
   727
    For example, refuting "hd xs = x", it presents the variable
wenzelm@47809
   728
    assignment xs = [] and x = a1 as a counterexample, assuming that
wenzelm@47809
   729
    any property is false whenever "hd []" occurs in it.
wenzelm@47809
   730
wenzelm@47809
   731
    These counterexample are marked as potentially spurious, as
wenzelm@47809
   732
    Quickcheck also returns "xs = []" as a counterexample to the
wenzelm@47809
   733
    obvious theorem "hd xs = hd xs".
wenzelm@47809
   734
wenzelm@47809
   735
    After finding a potentially spurious counterexample, Quickcheck
wenzelm@47809
   736
    continues searching for genuine ones.
wenzelm@47809
   737
wenzelm@47809
   738
    By default, Quickcheck shows potentially spurious and genuine
wenzelm@47809
   739
    counterexamples. The option "genuine_only" sets quickcheck to only
wenzelm@47809
   740
    show genuine counterexamples.
wenzelm@47809
   741
wenzelm@47809
   742
  - The command 'quickcheck_generator' creates random and exhaustive
wenzelm@47809
   743
    value generators for a given type and operations.
wenzelm@47809
   744
wenzelm@47809
   745
    It generates values by using the operations as if they were
wenzelm@47809
   746
    constructors of that type.
wenzelm@47809
   747
wenzelm@47809
   748
  - Support for multisets.
wenzelm@47809
   749
wenzelm@47809
   750
  - Added "use_subtype" options.
wenzelm@47809
   751
wenzelm@47809
   752
  - Added "quickcheck_locale" configuration to specify how to process
wenzelm@47809
   753
    conjectures in a locale context.
wenzelm@47809
   754
wenzelm@47855
   755
* Nitpick: Fixed infinite loop caused by the 'peephole_optim' option
wenzelm@47855
   756
and affecting 'rat' and 'real'.
wenzelm@47809
   757
wenzelm@47809
   758
* Sledgehammer:
wenzelm@47809
   759
  - Integrated more tightly with SPASS, as described in the ITP 2012
wenzelm@47809
   760
    paper "More SPASS with Isabelle".
wenzelm@47809
   761
  - Made it try "smt" as a fallback if "metis" fails or times out.
wenzelm@47809
   762
  - Added support for the following provers: Alt-Ergo (via Why3 and
wenzelm@47809
   763
    TFF1), iProver, iProver-Eq.
wenzelm@47809
   764
  - Sped up the minimizer.
wenzelm@47809
   765
  - Added "lam_trans", "uncurry_aliases", and "minimize" options.
wenzelm@47809
   766
  - Renamed "slicing" ("no_slicing") option to "slice" ("dont_slice").
wenzelm@47809
   767
  - Renamed "sound" option to "strict".
wenzelm@47809
   768
wenzelm@47855
   769
* Metis: Added possibility to specify lambda translations scheme as a
wenzelm@47855
   770
parenthesized argument (e.g., "by (metis (lifting) ...)").
wenzelm@47855
   771
wenzelm@47855
   772
* SMT: Renamed "smt_fixed" option to "smt_read_only_certificates".
wenzelm@47855
   773
wenzelm@47855
   774
* Command 'try0': Renamed from 'try_methods'. INCOMPATIBILITY.
wenzelm@47809
   775
wenzelm@47856
   776
* New "case_product" attribute to generate a case rule doing multiple
wenzelm@47856
   777
case distinctions at the same time.  E.g.
wenzelm@47856
   778
wenzelm@47856
   779
  list.exhaust [case_product nat.exhaust]
wenzelm@47856
   780
wenzelm@47856
   781
produces a rule which can be used to perform case distinction on both
wenzelm@47856
   782
a list and a nat.
wenzelm@47856
   783
wenzelm@47809
   784
* New "eventually_elim" method as a generalized variant of the
wenzelm@47855
   785
eventually_elim* rules.  Supports structured proofs.
wenzelm@47855
   786
wenzelm@47702
   787
* Typedef with implicit set definition is considered legacy.  Use
wenzelm@47702
   788
"typedef (open)" form instead, which will eventually become the
wenzelm@47702
   789
default.
wenzelm@47702
   790
wenzelm@47856
   791
* Record: code generation can be switched off manually with
wenzelm@47856
   792
wenzelm@47856
   793
  declare [[record_coden = false]]  -- "default true"
wenzelm@47856
   794
wenzelm@47856
   795
* Datatype: type parameters allow explicit sort constraints.
wenzelm@47856
   796
wenzelm@47855
   797
* Concrete syntax for case expressions includes constraints for source
wenzelm@47855
   798
positions, and thus produces Prover IDE markup for its bindings.
wenzelm@47855
   799
INCOMPATIBILITY for old-style syntax translations that augment the
wenzelm@47855
   800
pattern notation; e.g. see src/HOL/HOLCF/One.thy for translations of
wenzelm@47855
   801
one_case.
wenzelm@47855
   802
wenzelm@47855
   803
* Clarified attribute "mono_set": pure declaration without modifying
wenzelm@47855
   804
the result of the fact expression.
wenzelm@47855
   805
haftmann@46752
   806
* More default pred/set conversions on a couple of relation operations
wenzelm@47464
   807
and predicates.  Added powers of predicate relations.  Consolidation
wenzelm@47464
   808
of some relation theorems:
haftmann@46752
   809
haftmann@46752
   810
  converse_def ~> converse_unfold
haftmann@47549
   811
  rel_comp_def ~> relcomp_unfold
haftmann@47820
   812
  symp_def ~> (modified, use symp_def and sym_def instead)
haftmann@46752
   813
  transp_def ~> transp_trans
haftmann@46752
   814
  Domain_def ~> Domain_unfold
haftmann@46752
   815
  Range_def ~> Domain_converse [symmetric]
haftmann@46752
   816
haftmann@46981
   817
Generalized theorems INF_INT_eq, INF_INT_eq2, SUP_UN_eq, SUP_UN_eq2.
haftmann@46981
   818
wenzelm@47464

wenzelm@47809
  1260
machine word equalities and inequalities into logical circuits,
wenzelm@47809
  1261
defined in HOL/Word/WordBitwise.thy.  Supports addition, subtraction,
wenzelm@47809
  1262
multiplication, shifting by constants, bitwise operators and numeric
wenzelm@47809
  1263
constants.  Requires fixed-length word types, not 'a word.  Solves
wenzelm@47854
  1264
many standard word identities outright and converts more into first

  1265
order problems amenable to blast or similar.  See also examples in

* Session HOL-Probability: Introduced the type "'a measure" to
wenzelm@47807
  1269
represent measures, this replaces the records 'a algebra and 'a
wenzelm@47807
  1270
measure_space.  The locales based on subset_class now have two
wenzelm@47856
  1271
locale-parameters the space \<Omega> and the set of measurable sets M.
wenzelm@47856
  1272
The product of probability spaces uses now the same constant as the
wenzelm@47856
  1273
finite product of sigma-finite measure spaces "PiM :: ('i => 'a)
wenzelm@47807
  1274
measure".  Most constants are defined now outside of locales and gain
wenzelm@47807
  1275
an additional parameter, like null_sets, almost_eventually or \<mu>'.
wenzelm@47807
  1276
Measure space constructions for distributions and densities now got
wenzelm@47807
  1277
their own constants distr and density.  Instead of using locales to
wenzelm@47807
  1278
describe measure spaces with a finite space, the measure count_space
wenzelm@47807
  1279
and point_measure is introduced.  INCOMPATIBILITY.

  1547
    based on interactive editor view.  (Note: jEdit folding and
wenzelm@44760
  1548
    narrowing allows to restrict buffer perspectives explicitly.)
wenzelm@44760
  1549
wenzelm@44777
  1550
  - Reduced CPU performance requirements, usable on machines with few
wenzelm@44760
  1551
    cores.
wenzelm@44760
  1552
wenzelm@44777
  1553
  - Reduced memory requirements due to pruning of unused document
wenzelm@44760
  1554
    versions (garbage collection).

See also ~~/src/Tools/jEdit/README.html for further information,
wenzelm@44760
  1557
including some remaining limitations.
wenzelm@44760
  1558
wenzelm@44800
  1559
* Theory loader: source files are exclusively located via the master
wenzelm@44800
  1560
directory of each theory node (where the .thy file itself resides).
wenzelm@44800
  1561
The global load path (such as src/HOL/Library) has been discontinued.
wenzelm@44800
  1562
Note that the path element ~~ may be used to reference theories in the
wenzelm@44800
  1563
Isabelle home folder -- for instance, "~~/src/HOL/Library/FuncSet".
wenzelm@44800
  1564
INCOMPATIBILITY.
wenzelm@44800
  1565
wenzelm@41955
  1566
* Theory loader: source files are identified by content via SHA1
wenzelm@41955
  1567
digests.  Discontinued former path/modtime identification and optional
wenzelm@41955
  1568
ISABELLE_FILE_IDENT plugin scripts.
wenzelm@41955
  1569
wenzelm@41703
  1570
* Parallelization of nested Isar proofs is subject to
wenzelm@41703
  1571
Goal.parallel_proofs_threshold (default 100).  See also isabelle
wenzelm@41703
  1572
usedir option -Q.
wenzelm@41703
  1573
wenzelm@42669
  1574
* Name space: former unsynchronized references are now proper
wenzelm@42669
  1575
configuration options, with more conventional names:
wenzelm@42669
  1576
wenzelm@42669
  1577
  long_names   ~> names_long
wenzelm@42669
  1578
  short_names  ~> names_short
wenzelm@42669
  1579
  unique_names ~> names_unique
wenzelm@42669
  1580
wenzelm@42669
  1581
Minor INCOMPATIBILITY, need to declare options in context like this:
wenzelm@42669
  1582
wenzelm@42669
  1583
  declare [[names_unique = false]]
wenzelm@42358
  1584
wenzelm@42502
  1585
* Literal facts `prop` may contain dummy patterns, e.g. `_ = _`.  Note
wenzelm@42502
  1586
that the result needs to be unique, which means fact specifications
wenzelm@42502
  1587
may have to be refined after enriching a proof context.
wenzelm@42502
  1588
wenzelm@44800
  1589
* Attribute "case_names" has been refined: the assumptions in each case
wenzelm@44800
  1590
can be named now by following the case name with [name1 name2 ...].
wenzelm@44800
  1591
wenzelm@44968
  1592
* Isabelle/Isar reference manual has been updated and extended:
wenzelm@44968
  1593
  - "Synopsis" provides a catalog of main Isar language concepts.
wenzelm@44968
  1594
  - Formal references in syntax diagrams, via @{rail} antiquotation.
wenzelm@44968
  1595
  - Updated material from classic "ref" manual, notably about
wenzelm@44968
  1596
    "Classical Reasoner".

haftmann@43940
  1604
* Class complete_lattice: generalized a couple of lemmas from sets;
wenzelm@44800
  1605
generalized theorems INF_cong and SUP_cong.  New type classes for
wenzelm@44800
  1606
complete boolean algebras and complete linear orders.  Lemmas
wenzelm@44800
  1607
Inf_less_iff, less_Sup_iff, INF_less_iff, less_SUP_iff now reside in
wenzelm@44800
  1608
class complete_linorder.
wenzelm@44800
  1609
wenzelm@44800
  1610
Changed proposition of lemmas Inf_bool_def, Sup_bool_def, Inf_fun_def,
wenzelm@44800
  1611
Sup_fun_def, Inf_apply, Sup_apply.
wenzelm@44800
  1612
wenzelm@45088

INCOMPATIBILITY.
wenzelm@44973

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

wenzelm@44973
  1660
INCOMPATIBILITY.
wenzelm@44973
  1661
krauss@44845
  1662
* Added syntactic classes "inf" and "sup" for the respective
krauss@44845
  1663
constants.  INCOMPATIBILITY: Changes in the argument order of the
krauss@44845
  1664
(mostly internal) locale predicates for some derived classes.
krauss@44845
  1665
wenzelm@44800
  1666
* Theorem collections ball_simps and bex_simps do not contain theorems
wenzelm@44800
  1667
referring to UNION any longer; these have been moved to collection
wenzelm@44800
  1668
UN_ball_bex_simps.  INCOMPATIBILITY.
wenzelm@44800
  1669
wenzelm@44800

  1671
separate type class floor_ceiling.
wenzelm@44800
  1672
wenzelm@44800
  1673

  1679
adjustment.  INCOMPATIBILITY.
haftmann@42874
  1680
wenzelm@44800

wenzelm@44800
  1685
bounded_linear and bounded_bilinear locales have been removed, in
wenzelm@44800
  1686

  1784
generalized.  Now it is defined on the type class {topological_space,
wenzelm@44967

comm_monoid_add}.  Hence it is useable also for extended real numbers.
wenzelm@42484
  1786

  1787
* Theory Complex_Main: The complex exponential function "expi" is now
huffman@44908
  1788
a type-constrained abbreviation for "exp :: complex => complex"; thus
huffman@44908
  1789
several polymorphic lemmas about "exp" are now applicable to "expi".

* Code generation:
wenzelm@44968
  1792
wenzelm@44968
  1793
  - Theory Library/Code_Char_ord provides native ordering of

  1794
    characters in the target language.
wenzelm@44968
  1795
wenzelm@44968

  1797
    instead.
wenzelm@44968
  1798
wenzelm@44968
  1799
  - Method "evaluation" is legacy, use method "eval" instead.
wenzelm@44968
  1800
wenzelm@44968
  1801
  - Legacy evaluator "SML" is deactivated by default.  May be
wenzelm@44968

* Session Multivariate_Analysis: The euclidean_space type class now
wenzelm@44968
  1909
fixes a constant "Basis :: 'a set" consisting of the standard
wenzelm@44968
  1910
orthonormal basis for the type. Users now have the option of
wenzelm@44968
  1911
quantifying over this set instead of using the "basis" function, e.g.
wenzelm@44968
  1912
"ALL x:Basis. P x" vs "ALL i<DIM('a). P (basis i)".
wenzelm@44968
  1913
wenzelm@44968
  1914
* Session Multivariate_Analysis: Type "('a, 'b) cart" has been renamed

to "('a, 'b) vec" (the syntax "'a ^ 'b" remains unaffected). Constants
wenzelm@44968
  1916
"Cart_nth" and "Cart_lambda" have been respectively renamed to
wenzelm@44968
  1917
"vec_nth" and "vec_lambda"; theorems mentioning those names have
wenzelm@44968
  1918
changed to match. Definition theorems for overloaded constants now use
wenzelm@44968
  1919
the standard "foo_vec_def" naming scheme. A few other theorems have
wenzelm@44968
  1920
been renamed as follows (INCOMPATIBILITY):

wenzelm@42015
  2065
former start_timing/end_timing etc.
wenzelm@42015
  2066
wenzelm@41944

* Path.print is the official way to show file-system paths to users
wenzelm@41944
  2068
(including quotes etc.).
wenzelm@41944

wenzelm@42056
  2070
* Inner syntax: identifiers in parse trees of generic categories
wenzelm@42056
  2071
"logic", "aprop", "idt" etc. carry position information (disguised as
wenzelm@42056
  2072
type constraints).  Occasional INCOMPATIBILITY with non-compliant
wenzelm@42057
  2073
translations that choke on unexpected type constraints.  Positions can
wenzelm@42057
  2074
be stripped in ML translations via Syntax.strip_positions /
wenzelm@42057
  2075
Syntax.strip_positions_ast, or via the syntax constant
wenzelm@42057
  2076
"_strip_positions" within parse trees.  As last resort, positions can
wenzelm@42057
  2077
be disabled via the configuration option Syntax.positions, which is
wenzelm@42057
  2078
called "syntax_positions" in Isar attribute syntax.
wenzelm@42056
  2079
wenzelm@42290

* Discontinued special status of various ML structures that contribute
wenzelm@42290
  2081
to structure Syntax (Ast, Lexicon, Mixfix, Parser, Printer etc.): less
wenzelm@42290
  2082
pervasive content, no inclusion in structure Syntax.  INCOMPATIBILITY,
wenzelm@42290
  2083
refer directly to Ast.Constant, Lexicon.is_identifier,
wenzelm@42290

Syntax_Trans.mk_binder_tr etc.
wenzelm@42224
  2085
wenzelm@42247
  2086
* Typed print translation: discontinued show_sorts argument, which is
wenzelm@42247
  2087
already available via context of "advanced" translation.
wenzelm@42247
  2088
wenzelm@42370
  2089
* Refined PARALLEL_GOALS tactical: degrades gracefully for schematic
wenzelm@42370
  2090
goal states; body tactic needs to address all subgoals uniformly.
wenzelm@42370
  2091
wenzelm@42403
  2092
* Slightly more special eq_list/eq_set, with shortcut involving
wenzelm@42403
  2093
pointer equality (assumes that eq relation is reflexive).
wenzelm@42403
  2094
wenzelm@42793
  2095
* Classical tactics use proper Proof.context instead of historic types
wenzelm@42793
  2096
claset/clasimpset.  Old-style declarations like addIs, addEs, addDs
wenzelm@42793
  2097
operate directly on Proof.context.  Raw type claset retains its use as
wenzelm@42793
  2098
snapshot of the classical context, which can be recovered via
wenzelm@42793
  2099
(put_claset HOL_cs) etc.  Type clasimpset has been discontinued.
wenzelm@42793
  2100
INCOMPATIBILITY, classical tactics and derived proof methods require
wenzelm@42793
  2101
proper Proof.context.

  2107
without proper multithreading and TimeLimit implementation.
wenzelm@44968

wenzelm@44968
  2110
obsolete since Isabelle2009-2.
wenzelm@44968
  2111
wenzelm@44967
  2112
* Various optional external tools are referenced more robustly and
wenzelm@44967
  2113
uniformly by explicit Isabelle settings as follows:
wenzelm@44967
  2114
wenzelm@44967
  2115
  ISABELLE_CSDP   (formerly CSDP_EXE)
wenzelm@44967
  2116
  ISABELLE_GHC    (formerly EXEC_GHC or GHC_PATH)
wenzelm@44967
  2117
  ISABELLE_OCAML  (formerly EXEC_OCAML)
wenzelm@44967
  2118
  ISABELLE_SWIPL  (formerly EXEC_SWIPL)

  2119
  ISABELLE_YAP    (formerly EXEC_YAP)
wenzelm@44967
  2120
wenzelm@44967
  2121
Note that automated detection from the file-system or search path has
wenzelm@44967
  2122
been discontinued.  INCOMPATIBILITY.
wenzelm@44967
  2123
wenzelm@43752
  2124
* Scala layer provides JVM method invocation service for static
wenzelm@44800
  2125
methods of type (String)String, see Invoke_Scala.method in ML.  For
wenzelm@44800
  2126
example:
wenzelm@43752
  2127
wenzelm@43752
  2128
  Invoke_Scala.method "java.lang.System.getProperty" "java.home"
wenzelm@43752
  2129
wenzelm@44967
  2130
Together with YXML.string_of_body/parse_body and XML.Encode/Decode
wenzelm@44967
  2131
this allows to pass structured values between ML and Scala.
wenzelm@44800

* The IsabelleText fonts includes some further glyphs to support the
wenzelm@44803
  2134
Prover IDE.  Potential INCOMPATIBILITY: users who happen to have
wenzelm@44803

installed a local copy (which is normally *not* required) need to
wenzelm@44803

  2143
*** General ***
wenzelm@37536
  2144
wenzelm@41573
  2145
* Experimental Prover IDE based on Isabelle/Scala and jEdit (see
wenzelm@41612
  2146
src/Tools/jEdit).  This also serves as IDE for Isabelle/ML, with
wenzelm@41612
  2147
useful tooltips and hyperlinks produced from its static analysis.  The
wenzelm@41612
  2148
bundled component provides an executable Isabelle tool that can be run
wenzelm@41612
  2149
like this:
wenzelm@41612
  2150
wenzelm@41612
  2151
  Isabelle2011/bin/isabelle jedit
wenzelm@41573
  2152
wenzelm@40948
  2153
* Significantly improved Isabelle/Isar implementation manual.
wenzelm@40948
  2154
wenzelm@41594
  2155
* System settings: ISABELLE_HOME_USER now includes ISABELLE_IDENTIFIER
wenzelm@41595
  2156
(and thus refers to something like $HOME/.isabelle/Isabelle2011),
wenzelm@41594
  2157
while the default heap location within that directory lacks that extra
wenzelm@41594
  2158
suffix.  This isolates multiple Isabelle installations from each
wenzelm@41594
  2159
other, avoiding problems with old settings in new versions.
wenzelm@41594
  2160
INCOMPATIBILITY, need to copy/upgrade old user settings manually.
wenzelm@41594
  2161
wenzelm@40947
  2162
* Source files are always encoded as UTF-8, instead of old-fashioned
wenzelm@40947
  2163
ISO-Latin-1.  INCOMPATIBILITY.  Isabelle LaTeX documents might require
wenzelm@40948
  2164
the following package declarations:
wenzelm@40947
  2165
wenzelm@40947
  2166
  \usepackage[utf8]{inputenc}
wenzelm@40947
  2167
  \usepackage{textcomp}
wenzelm@40947
  2168
krauss@41440
  2169
* Explicit treatment of UTF-8 sequences as Isabelle symbols, such that
wenzelm@37536
  2170
a Unicode character is treated as a single symbol, not a sequence of
wenzelm@37536
  2171
non-ASCII bytes as before.  Since Isabelle/ML string literals may
wenzelm@37536
  2172
contain symbols without further backslash escapes, Unicode can now be
wenzelm@37536
  2173
used here as well.  Recall that Symbol.explode in ML provides a
wenzelm@37536
  2174
consistent view on symbols, while raw explode (or String.explode)
wenzelm@37536
  2175
merely give a byte-oriented representation.
wenzelm@37536
  2176
wenzelm@41594
  2177
* Theory loader: source files are primarily located via the master
wenzelm@41594
  2178
directory of each theory node (where the .thy file itself resides).
wenzelm@41594
  2179
The global load path is still partially available as legacy feature.
wenzelm@41594
  2180
Minor INCOMPATIBILITY due to subtle change in file lookup: use
wenzelm@41594
  2181
explicit paths, relatively to the theory.
wenzelm@38135
  2182
wenzelm@37939
  2183
* Special treatment of ML file names has been discontinued.
wenzelm@37939
  2184
Historically, optional extensions .ML or .sml were added on demand --
wenzelm@37939
  2185
at the cost of clarity of file dependencies.  Recall that Isabelle/ML
wenzelm@37939
  2186
files exclusively use the .ML extension.  Minor INCOMPATIBILTY.
wenzelm@37939
  2187
wenzelm@38980
  2188
* Various options that affect pretty printing etc. are now properly
wenzelm@38767
  2189
handled within the context via configuration options, instead of
wenzelm@40879
  2190
unsynchronized references or print modes.  There are both ML Config.T
wenzelm@40879

The option "show_abbrevs" supersedes the former print mode

  2221
"no_abbrevs" with inverted meaning.
wenzelm@38767

lists of equations to map definitions in a locale to appropriate
ballarin@41435
  2257
entities in the context of the interpretation.  The 'interpretation'
ballarin@41435
  2258
command already provided this functionality.
ballarin@41435
  2259
wenzelm@41594
  2260
* Diagnostic command 'print_dependencies' prints the locale instances
wenzelm@41594
  2261
that would be activated if the specified expression was interpreted in
wenzelm@41594
  2262
the current context.  Variant "print_dependencies!" assumes a context
wenzelm@41594
  2263
without interpretations.
ballarin@38110
  2264
ballarin@38110

Sign.root_path and Sign.local_path may be applied directly where this

* Coercive subtyping: functions can be declared as coercions and type
wenzelm@41594
  2291
inference will add them as necessary upon input of a term.  Theory
wenzelm@41594
  2292
Complex_Main declares real :: nat => real and real :: int => real as
wenzelm@41594
  2293
coercions. A coercion function f is declared like this:
wenzelm@40939
  2294
wenzelm@40939
  2295
  declare [[coercion f]]
nipkow@40866
  2296
wenzelm@41571
  2297
To lift coercions through type constructors (e.g. from nat => real to
nipkow@40866
  2298
nat list => real list), map functions can be declared, e.g.
nipkow@40866
  2299
wenzelm@40939
  2300
  declare [[coercion_map map]]
wenzelm@40939
  2301
wenzelm@40939
  2302
Currently coercion inference is activated only in theories including
wenzelm@40939
  2303
real numbers, i.e. descendants of Complex_Main.  This is controlled by
wenzelm@41020
  2304
the configuration option "coercion_enabled", e.g. it can be enabled in
wenzelm@40939
  2305
other theories like this:
wenzelm@40939
  2306
wenzelm@40939

  2336
have been replaced by the more idiomatic "_" and "Theory._".
haftmann@41398
  2337
INCOMPATIBILITY.
haftmann@41398
  2338
haftmann@41398
  2339
* Code generator: export_code without explicit file declaration prints
haftmann@41398
  2340
to standard output.  INCOMPATIBILITY.
haftmann@41398
  2341
haftmann@41398
  2342
* Code generator: do not print function definitions for case
haftmann@41398
  2343
combinators any longer.
haftmann@41398
  2344
wenzelm@41594
  2345
* Code generator: simplification with rules determined with
wenzelm@41571
  2346
src/Tools/Code/code_simp.ML and method "code_simp".
wenzelm@41571
  2347
wenzelm@41594
  2348
* Code generator for records: more idiomatic representation of record
wenzelm@40948
  2349
types.  Warning: records are not covered by ancient SML code
wenzelm@40948
  2350
generation any longer.  INCOMPATIBILITY.  In cases of need, a suitable
wenzelm@40948
  2351
rep_datatype declaration helps to succeed then:
haftmann@38537
  2352
haftmann@38537
  2353
  record 'a foo = ...
haftmann@38537
  2354

haftmann@38537
  2355
  rep_datatype foo_ext ...
haftmann@38535
  2356
wenzelm@41594
  2357
* Records: logical foundation type for records does not carry a
wenzelm@41594
  2358
'_type' suffix any longer (obsolete due to authentic syntax).
wenzelm@41594
  2359
INCOMPATIBILITY.
wenzelm@41594
  2360
haftmann@41398
  2361
* Quickcheck now by default uses exhaustive testing instead of random
wenzelm@41571
  2362
testing.  Random testing can be invoked by "quickcheck [random]",
wenzelm@41571
  2363
exhaustive testing by "quickcheck [exhaustive]".
haftmann@41398
  2364
haftmann@41398
  2365
* Quickcheck instantiates polymorphic types with small finite
haftmann@41398
  2366
datatypes by default. This enables a simple execution mechanism to
haftmann@41398
  2367
handle quantifiers and function equality over the finite datatypes.
haftmann@41398
  2368
wenzelm@41571
  2369
* Quickcheck random generator has been renamed from "code" to
wenzelm@41571
  2370
"random".  INCOMPATIBILITY.
haftmann@41398
  2371
haftmann@41398
  2372
* Quickcheck now has a configurable time limit which is set to 30
haftmann@41398
  2373
seconds by default. This can be changed by adding [timeout = n] to the
haftmann@41398
  2374
quickcheck command. The time limit for Auto Quickcheck is still set
haftmann@41398
  2375
independently.
haftmann@38461
  2376
haftmann@38461
  2377
* Quickcheck in locales considers interpretations of that locale for
haftmann@38461
  2378
counter example search.

  2379
blanchet@40059
  2380
* Sledgehammer:
wenzelm@41571
  2381
  - Added "smt" and "remote_smt" provers based on the "smt" proof
wenzelm@41571
  2382
    method. See the Sledgehammer manual for details ("isabelle doc
wenzelm@41571
  2383
    sledgehammer").
blanchet@40059
  2384
  - Renamed commands:
blanchet@40059
  2385
    sledgehammer atp_info ~> sledgehammer running_provers
blanchet@40059
  2386
    sledgehammer atp_kill ~> sledgehammer kill_provers
blanchet@40059

    sledgehammer available_atps ~> sledgehammer available_provers
blanchet@40059
  2388
    INCOMPATIBILITY.
blanchet@40059
  2389
  - Renamed options:

  2390
    sledgehammer [atps = ...] ~> sledgehammer [provers = ...]
blanchet@40062
  2391
    sledgehammer [atp = ...] ~> sledgehammer [prover = ...]
blanchet@40341
  2392
    sledgehammer [timeout = 77 s] ~> sledgehammer [timeout = 77]
blanchet@40341
  2393
    (and "ms" and "min" are no longer supported)
blanchet@40341
  2394
    INCOMPATIBILITY.
blanchet@40341
  2395
blanchet@40341
  2396
* Nitpick:
blanchet@40341
  2397
  - Renamed options:
blanchet@40341
  2398
    nitpick [timeout = 77 s] ~> nitpick [timeout = 77]
blanchet@40341
  2399
    nitpick [tac_timeout = 777 ms] ~> nitpick [tac_timeout = 0.777]
blanchet@40059
  2400
    INCOMPATIBILITY.
blanchet@40725
  2401
  - Added support for partial quotient types.
blanchet@40725
  2402
  - Added local versions of the "Nitpick.register_xxx" functions.
blanchet@40725
  2403
  - Added "whack" option.
blanchet@40725
  2404
  - Allow registration of quotient types as codatatypes.
blanchet@40725
  2405
  - Improved "merge_type_vars" option to merge more types.
blanchet@40725
  2406
  - Removed unsound "fast_descrs" option.
blanchet@40725
  2407
  - Added custom symmetry breaking for datatypes, making it possible to reach
blanchet@40725
  2408
    higher cardinalities.
blanchet@40725
  2409
  - Prevent the expansion of too large definitions.
blanchet@39957
  2410
wenzelm@41571
  2411
* Proof methods "metis" and "meson" now have configuration options
wenzelm@41571
  2412
"meson_trace", "metis_trace", and "metis_verbose" that can be enabled
wenzelm@41571
  2413
to diagnose these tools. E.g.
wenzelm@41571
  2414
wenzelm@41571
  2415
    using [[metis_trace = true]]
wenzelm@41571
  2416
haftmann@41398
  2417
* Auto Solve: Renamed "Auto Solve Direct".  The tool is now available
haftmann@41398
  2418
manually as command 'solve_direct'.
haftmann@41398
  2419
boehmes@41601
  2420
* The default SMT solver Z3 must be enabled explicitly (due to
boehmes@41601
  2421
licensing issues) by setting the environment variable
wenzelm@41603
  2422
Z3_NON_COMMERCIAL in etc/settings of the component, for example.  For
wenzelm@41603
  2423
commercial applications, the SMT solver CVC3 is provided as fall-back;
wenzelm@41603
  2424
changing the SMT solver is done via the configuration option
wenzelm@41603
  2425
"smt_solver".
boehmes@41432
  2426
boehmes@41432
  2427
* Remote SMT solvers need to be referred to by the "remote_" prefix,
wenzelm@41571
  2428
i.e. "remote_cvc3" and "remote_z3".
wenzelm@41571
  2429
wenzelm@41571
  2430
* Added basic SMT support for datatypes, records, and typedefs using
wenzelm@41571
  2431
the oracle mode (no proofs).  Direct support of pairs has been dropped
wenzelm@41571
  2432
in exchange (pass theorems fst_conv snd_conv pair_collapse to the SMT
wenzelm@41571
  2433
support for a similar behavior).  Minor INCOMPATIBILITY.
boehmes@41432
  2434
boehmes@40162
  2435
* Changed SMT configuration options:
boehmes@40162
  2436
  - Renamed:
boehmes@41432
  2437
    z3_proofs ~> smt_oracle (with inverted meaning)
boehmes@40162
  2438
    z3_trace_assms ~> smt_trace_used_facts
boehmes@40162
  2439
    INCOMPATIBILITY.
boehmes@40162
  2440
  - Added:

  2450
wenzelm@40948
  2451
* Boogie output files (.b2i files) need to be declared in the theory
wenzelm@40948
  2452
header.
boehmes@40580
  2453
wenzelm@41594
  2454
* Simplification procedure "list_to_set_comprehension" rewrites list
wenzelm@41594
  2455
comprehensions applied to List.set to set comprehensions.  Occasional
wenzelm@41594
  2456
INCOMPATIBILITY, may be deactivated like this:
wenzelm@41594
  2457
wenzelm@41594
  2458
  declare [[simproc del: list_to_set_comprehension]]
wenzelm@41594
  2459
wenzelm@41573
  2460
* Removed old version of primrec package.  INCOMPATIBILITY.
haftmann@41398
  2461
haftmann@41398
  2462
* Removed simplifier congruence rule of "prod_case", as has for long
haftmann@41398
  2463
been the case with "split".  INCOMPATIBILITY.
haftmann@41398
  2464
haftmann@41398
  2465
* String.literal is a type, but not a datatype.  INCOMPATIBILITY.
haftmann@41398
  2466
krauss@40388
  2467
* Removed [split_format ... and ... and ...] version of
krauss@40388
  2468
[split_format].  Potential INCOMPATIBILITY.
krauss@40388
  2469
wenzelm@41571
  2470
* Predicate "sorted" now defined inductively, with nice induction
wenzelm@41571
  2471
rules.  INCOMPATIBILITY: former sorted.simps now named sorted_simps.
haftmann@41398
  2472
haftmann@41398
  2473
* Constant "contents" renamed to "the_elem", to free the generic name
haftmann@41398
  2474
contents for other uses.  INCOMPATIBILITY.
haftmann@41398
  2475
haftmann@41398
  2476
* Renamed class eq and constant eq (for code generation) to class
haftmann@41398
  2477
equal and constant equal, plus renaming of related facts and various
haftmann@41398
  2478
tuning.  INCOMPATIBILITY.
haftmann@41398
  2479
haftmann@41398
  2480
* Dropped type classes mult_mono and mult_mono1.  INCOMPATIBILITY.
haftmann@41398
  2481
wenzelm@41571
  2482
* Removed output syntax "'a ~=> 'b" for "'a => 'b option".
wenzelm@41571
  2483
INCOMPATIBILITY.
haftmann@41398
  2484
haftmann@41398
  2485
* Renamed theory Fset to Cset, type Fset.fset to Cset.set, in order to
haftmann@41398
  2486
avoid confusion with finite sets.  INCOMPATIBILITY.
haftmann@41398
  2487
haftmann@41398
  2488
* Abandoned locales equiv, congruent and congruent2 for equivalence
haftmann@41398
  2489
relations.  INCOMPATIBILITY: use equivI rather than equiv_intro (same
haftmann@41398
  2490
for congruent(2)).
haftmann@41398
  2491
haftmann@41398

INCOMPATIBILITY.
haftmann@41398
  2524
haftmann@41398
  2525

INCOMPATIBILITY.  Note that these were not supposed to be used
haftmann@41398
  2557
regularly unless for striking reasons; their main purpose was code
haftmann@41398
  2558
generation.
haftmann@41398
  2559
haftmann@41398
  2560
Various operations from the Haskell prelude are used for generating

  2561
Haskell code.
haftmann@41398
  2562
wenzelm@41571

"surj f" is now an abbreviation of "range f = UNIV".  The theorems
wenzelm@41571
  2565
bij_def and surj_def are unchanged.  INCOMPATIBILITY.
haftmann@41398
  2566
haftmann@41398

  2568
"*" and "+" respectively.  INCOMPATIBILITY.
haftmann@41398
  2569
haftmann@41398

  2571
"Sum_Type.Plus" instead.
haftmann@41398
  2572
haftmann@41398
  2573
* Constant "split" has been merged with constant "prod_case"; names of
haftmann@41398

ML functions, facts etc. involving split have been retained so far,
haftmann@41398
  2575
though.  INCOMPATIBILITY.
haftmann@41398
  2576
haftmann@41398
  2577

haftmann@41398
  2579
wenzelm@41571

  2629
arbitrary sigma finite measures.  Introduces Lebesgue measure based on

* Theorems for additive ring operations (locale abelian_monoid and

counterparts.  Names (in particular theorem names) have the mandatory

* The domain package now runs in definitional mode by default: The
wenzelm@41571
  2655
former command 'new_domain' is now called 'domain'.  To use the domain
huffman@40621

* The new class "domain" is now the default sort.  Class "predomain"
wenzelm@41571
  2660
is an unpointed version of "domain". Theories can be updated by
wenzelm@41571

replacing sort annotations as shown below.  INCOMPATIBILITY.

huffman@40621
  2668
Accordingly, users of the definitional package must remove any

"default_sort rep" declarations.  INCOMPATIBILITY.

* The domain package (definitional mode) now supports unpointed
huffman@41401
  2672
predomain argument types, as long as they are marked 'lazy'. (Strict
wenzelm@41571
  2673
arguments must be in class "domain".) For example, the following
huffman@41401
  2674
domain definition now works:
huffman@41401
  2675
huffman@41401
  2676
  domain natlist = nil | cons (lazy "nat discr") (lazy "natlist")
huffman@41401
  2677
huffman@41401
  2678
* Theory HOLCF/Library/HOL_Cpo provides cpo and predomain class
wenzelm@41571
  2679
instances for types from main HOL: bool, nat, int, char, 'a + 'b,
wenzelm@41571
  2680
'a option, and 'a list.  Additionally, it configures fixrec and the
wenzelm@41571
  2681
domain package to work with these types.  For example:
huffman@41401
  2682
huffman@41401
  2683
  fixrec isInl :: "('a + 'b) u -> tr"
huffman@41401
  2684
    where "isInl$(up$(Inl x)) = TT" | "isInl$(up$(Inr y)) = FF"
huffman@41401
  2685
huffman@41401
  2686
  domain V = VFun (lazy "V -> V") | VCon (lazy "nat") (lazy "V list")
huffman@41401
  2687
wenzelm@41571
  2688
* The "(permissive)" option of fixrec has been replaced with a
wenzelm@41571
  2689
per-equation "(unchecked)" option. See
wenzelm@41571
  2690
src/HOL/HOLCF/Tutorial/Fixrec_ex.thy for examples. INCOMPATIBILITY.
wenzelm@41571
  2691
wenzelm@41571
  2692
* The "bifinite" class no longer fixes a constant "approx"; the class
wenzelm@41571
  2693
now just asserts that such a function exists.  INCOMPATIBILITY.
wenzelm@41571
  2694
wenzelm@41571
  2695
* Former type "alg_defl" has been renamed to "defl".  HOLCF no longer
huffman@41287
  2696
defines an embedding of type 'a defl into udom by default; instances
wenzelm@41571
  2697
of "bifinite" and "domain" classes are available in
wenzelm@41571
  2698
src/HOL/HOLCF/Library/Defl_Bifinite.thy.
wenzelm@41571
  2699
wenzelm@41571

* The syntax "REP('a)" has been replaced with "DEFL('a)".
wenzelm@41571
  2701
wenzelm@41571
  2702
* The predicate "directed" has been removed.  INCOMPATIBILITY.
wenzelm@41571

* The monadic bind operator on each powerdomain has new binder syntax
wenzelm@41571
  2710
similar to sets, e.g. "\<Union>\<sharp>x\<in>xs. t" represents
wenzelm@41571
  2711
"upper_bind\<cdot>xs\<cdot>(\<Lambda> x. t)".
huffman@41401
  2712
huffman@41401
  2713
* The infix syntax for binary union on each powerdomain has changed
wenzelm@41571
  2714
from e.g. "+\<sharp>" to "\<union>\<sharp>", for consistency with set
