* Discontinued obsolete 'uses' within theory header.  Note that
wenzelm@51293
    10
commands like 'ML_file' work without separate declaration of file
wenzelm@51293
    11
dependencies.  Minor INCOMPATIBILITY.
wenzelm@51293
    12
wenzelm@51295
    13
* Discontinued redundant 'use' command, which was superseded by
wenzelm@51295
    14
'ML_file' in Isabelle2013.  Minor INCOMPATIBILITY.

wenzelm@51313
    19
* Discontinued obsolete 'axioms' command, which has been marked as
wenzelm@51313
    20
legacy since Isabelle2009-2.  INCOMPATIBILITY, use 'axiomatization'
wenzelm@51313
    21
instead, while observing its uniform scope for polymorphism.
wenzelm@51313
    22
wenzelm@51316
    23
* Discontinued empty name bindings in 'axiomatization'.
wenzelm@51316

haftmann@51382
    29
* Discontinued theory src/HOL/Library/Eval_Witness.
haftmann@51382
    30
INCOMPATIBILITY.
haftmann@51382
    31
wenzelm@51238
    32
* Discontinued obsolete src/HOL/IsaMakefile (considered legacy since
wenzelm@51238
    33
Isabelle2013).  Use "isabelle build" to operate on Isabelle sessions.
wenzelm@51238
    34
haftmann@51168
    35
* Numeric types mapped by default to target language numerals:
haftmann@51168
    36
natural (replaces former code_numeral) and integer (replaces
haftmann@51168
    37
former code_int).  Conversions are available as integer_of_natural /
haftmann@51168
    38
natural_of_integer / integer_of_nat / nat_of_integer (in HOL) and
haftmann@51168
    39
Code_Numeral.integer_of_natural / Code_Numeral.natural_of_integer (in ML).
haftmann@51168
    40
INCOMPATIBILITY.
haftmann@51168
    41
haftmann@51168
    42
* Discontinued theories Code_Integer and Efficient_Nat by a more
haftmann@51168
    43
fine-grain stack of theories Code_Target_Int, Code_Binary_Nat,
haftmann@51168
    44
Code_Target_Nat and Code_Target_Numeral.  See the tutorial on
haftmann@51168
    45
code generation for details.  INCOMPATIBILITY.
haftmann@51168
    46
hoelzl@51002
    47
* Theory "RealVector" and "Limits": Introduce type class
hoelzl@51002
    48
(lin)order_topology. Allows to generalize theorems about limits and
hoelzl@51002
    49
order. Instances are reals and extended reals.
hoelzl@51002
    50
haftmann@51115
    51
* Consolidation of library theories on product orders:
haftmann@51115
    52
haftmann@51115
    53
    Product_Lattice ~> Product_Order -- pointwise order on products
haftmann@51115
    54
    Product_ord ~> Product_Lexorder -- lexicographic order on products
haftmann@51115
    55
haftmann@51115
    56
INCOMPATIBILITY.

blanchet@51137
    58
* Sledgehammer:
blanchet@51137
    59
blanchet@51137
    60
  - Renamed option:
blanchet@51137
    61
      isar_shrink ~> isar_compress

*** System ***
wenzelm@51398
    65
wenzelm@51398
    66
* Discontinued "isabelle usedir" option -P (remote path).  Note that
wenzelm@51398
    67
usedir is legacy and superseded by "isabelle build" since
wenzelm@51398
    68
Isabelle2013.

wenzelm@47887
    74
wenzelm@47967
    75
*** General ***
wenzelm@47967
    76
wenzelm@50126
    77
* Theorem status about oracles and unfinished/failed future proofs is
wenzelm@50126
    78
no longer printed by default, since it is incompatible with
wenzelm@50126
    79
incremental / parallel checking of the persistent document model.  ML
wenzelm@50126
    80
function Thm.peek_status may be used to inspect a snapshot of the
wenzelm@50126
    81
ongoing evaluation process.  Note that in batch mode --- notably
wenzelm@50126
    82
isabelle build --- the system ensures that future proofs of all
wenzelm@50126
    83
accessible theorems in the theory context are finished (as before).
wenzelm@50126
    84
wenzelm@49699
    85
* Configuration option show_markup controls direct inlining of markup
wenzelm@49699
    86
into the printed representation of formal entities --- notably type
wenzelm@49699
    87
and sort constraints.  This enables Prover IDE users to retrieve that
wenzelm@49699
    88
information via tooltips in the output window, for example.
wenzelm@49699
    89
wenzelm@48890
    90
* Command 'ML_file' evaluates ML text from a file directly within the
wenzelm@48890
    91
theory, without any predeclaration via 'uses' in the theory header.
wenzelm@48890
    92
wenzelm@49243
    93
* Old command 'use' command and corresponding keyword 'uses' in the
wenzelm@49243
    94
theory header are legacy features and will be discontinued soon.
wenzelm@49243
    95
Tools that load their additional source files may imitate the
wenzelm@49243
    96
'ML_file' implementation, such that the system can take care of
wenzelm@49243
    97
dependencies properly.
wenzelm@49243
    98
wenzelm@47967
    99
* Discontinued obsolete method fastsimp / tactic fast_simp_tac, which
wenzelm@47967
   100
is called fastforce / fast_force_tac already since Isabelle2011-1.
wenzelm@47967
   101
wenzelm@50110
   102
* Updated and extended "isar-ref" and "implementation" manual, reduced
wenzelm@50110
   103
remaining material in old "ref" manual.
wenzelm@48120
   104
wenzelm@51050
   105
* Improved support for auxiliary contexts that indicate block structure
wenzelm@51050
   106
for specifications.  Nesting of "context fixes ... context assumes ..."
wenzelm@49841
   107
and "class ... context ...".
wenzelm@49841
   108
wenzelm@50772
   109
* Attribute "consumes" allows a negative value as well, which is
wenzelm@50778
   110
interpreted relatively to the total number of premises of the rule in
wenzelm@50772
   111
the target context.  This form of declaration is stable when exported
wenzelm@50772
   112
from a nested 'context' with additional assumptions.  It is the
wenzelm@50772
   113
preferred form for definitional packages, notably cases/rules produced
wenzelm@50772
   114
in HOL/inductive and HOL/function.
wenzelm@50772
   115
wenzelm@49869
   116
* More informative error messages for Isar proof commands involving
wenzelm@49869
   117
lazy enumerations (method applications etc.).
wenzelm@49869
   118
wenzelm@50213
   119
* Refined 'help' command to retrieve outer syntax commands according
wenzelm@50213
   120
to name patterns (with clickable results).
wenzelm@50213
   121
wenzelm@47967
   122
wenzelm@49968
   123
*** Prover IDE -- Isabelle/Scala/jEdit ***
wenzelm@49968
   124
wenzelm@49968
   125
* Parallel terminal proofs ('by') are enabled by default, likewise
wenzelm@49968
   126
proofs that are built into packages like 'datatype', 'function'.  This
wenzelm@49968
   127
allows to "run ahead" checking the theory specifications on the
wenzelm@49968
   128
surface, while the prover is still crunching on internal
wenzelm@49968
   129
justifications.  Unfinished / cancelled proofs are restarted as
wenzelm@49968
   130
required to complete full proof checking eventually.
wenzelm@49968
   131
wenzelm@49968
   132
* Improved output panel with tooltips, hyperlinks etc. based on the
wenzelm@49968
   133
same Rich_Text_Area as regular Isabelle/jEdit buffers.  Activation of
wenzelm@49968
   134
tooltips leads to some window that supports the same recursively,
wenzelm@49968
   135
which can lead to stacks of tooltips as the semantic document content
wenzelm@49968
   136
is explored.  ESCAPE closes the whole stack, individual windows may be
wenzelm@49968
   137
closed separately, or detached to become independent jEdit dockables.
wenzelm@49968
   138
wenzelm@50717
   139
* Improved support for commands that produce graph output: the text
wenzelm@50717
   140
message contains a clickable area to open a new instance of the graph
wenzelm@50717
   141
browser on demand.
wenzelm@50717
   142
wenzelm@49968
   143
* More robust incremental parsing of outer syntax (partial comments,
wenzelm@49968
   144
malformed symbols).  Changing the balance of open/close quotes and
wenzelm@49968
   145
comment delimiters works more conveniently with unfinished situations
wenzelm@49968
   146
that frequently occur in user interaction.
wenzelm@49968
   147
wenzelm@49968
   148
* More efficient painting and improved reactivity when editing large
wenzelm@49968
   149
files.  More scalable management of formal document content.
wenzelm@49968
   150
wenzelm@50505
   151
* Smarter handling of tracing messages: prover process pauses after
wenzelm@50505
   152
certain number of messages per command transaction, with some user
wenzelm@50505
   153
dialog to stop or continue.  This avoids swamping the front-end with
wenzelm@50119
   154
potentially infinite message streams.
wenzelm@49968
   155
wenzelm@49968
   156
* More plugin options and preferences, based on Isabelle/Scala.  The
wenzelm@49968
   157
jEdit plugin option panel provides access to some Isabelle/Scala
wenzelm@49968
   158
options, including tuning parameters for editor reactivity and color
wenzelm@49968
   159
schemes.
wenzelm@49968
   160
wenzelm@50184
   161
* Dockable window "Symbols" provides some editing support for Isabelle
wenzelm@50184
   162
symbols.
wenzelm@50184
   163
wenzelm@51082
   164
* Dockable window "Monitor" shows ML runtime statistics.  Note that
wenzelm@51082
   165
continuous display of the chart slows down the system.
wenzelm@50701
   166
wenzelm@50183
   167
* Improved editing support for control styles: subscript, superscript,
wenzelm@50183
   168
bold, reset of style -- operating on single symbols or text
wenzelm@50198
   169
selections.  Cf. keyboard shortcuts C+e DOWN/UP/RIGHT/LEFT.
wenzelm@50198
   170
wenzelm@50198
   171
* Actions isabelle.increase-font-size and isabelle.decrease-font-size
wenzelm@50198
   172
adjust the main text area font size, and its derivatives for output,
wenzelm@50836
   173
tooltips etc.  Cf. keyboard shortcuts C-PLUS and C-MINUS, which often
wenzelm@50836
   174
need to be adapted to local keyboard layouts.
wenzelm@50183
   175
wenzelm@50730
   176
* More reactive completion popup by default: use \t (TAB) instead of
wenzelm@50730
   177
\n (NEWLINE) to minimize intrusion into regular flow of editing.  See
wenzelm@50730
   178
also "Plugin Options / SideKick / General / Code Completion Options".
wenzelm@50730
   179
wenzelm@50406
   180
* Implicit check and build dialog of the specified logic session
wenzelm@50406
   181
image.  For example, HOL, HOLCF, HOL-Nominal can be produced on
wenzelm@50406
   182
demand, without bundling big platform-dependent heap images in the
wenzelm@50406
   183
Isabelle distribution.
wenzelm@50406
   184
wenzelm@49968
   185
* Uniform Java 7 platform on Linux, Mac OS X, Windows: recent updates
wenzelm@49968
   186
from Oracle provide better multi-platform experience.  This version is
wenzelm@49968
   187
now bundled exclusively with Isabelle.
wenzelm@49968

*** Pure ***
wenzelm@48205
   191
haftmann@48431
   192
* Code generation for Haskell: restrict unqualified imports from
haftmann@48431
   193
Haskell Prelude to a small set of fundamental operations.
haftmann@48431
   194
wenzelm@50646
   195
* Command 'export_code': relative file names are interpreted
wenzelm@50646
   196
relatively to master directory of current theory rather than the
wenzelm@50646
   197
rather arbitrary current working directory.  INCOMPATIBILITY.
haftmann@48371
   198
wenzelm@48205
   199
* Discontinued obsolete attribute "COMP".  Potential INCOMPATIBILITY,
wenzelm@48205
   200
use regular rule composition via "OF" / "THEN", or explicit proof
wenzelm@48205
   201
structure instead.  Note that Isabelle/ML provides a variety of
wenzelm@48205
   202
operators like COMP, INCR_COMP, COMP_INCR, which need to be applied
wenzelm@48205
   203
with some care where this is really required.
wenzelm@48205
   204
wenzelm@48792
   205
* Command 'typ' supports an additional variant with explicit sort
wenzelm@48792
   206
constraint, to infer and check the most general type conforming to a
wenzelm@51063
   207
given sort.  Example (in HOL):
wenzelm@48792
   208
wenzelm@48792
   209
  typ "_ * _ * bool * unit" :: finite
wenzelm@48792
   210
wenzelm@50716
   211
* Command 'locale_deps' visualizes all locales and their relations as
wenzelm@50716
   212
a Hasse diagram.
wenzelm@50716

*** HOL ***
bulwahn@48013
   216
wenzelm@50646
   217
* Sledgehammer:
wenzelm@50646
   218
wenzelm@50646
   219
  - Added MaSh relevance filter based on machine-learning; see the
wenzelm@50646
   220
    Sledgehammer manual for details.
wenzelm@50646
   221
  - Polished Isar proofs generated with "isar_proofs" option.
wenzelm@50646
   222
  - Rationalized type encodings ("type_enc" option).
blanchet@50720
   223
  - Renamed "kill_provers" subcommand to "kill_all".
wenzelm@50646
   224
  - Renamed options:
wenzelm@50646
   225
      isar_proof ~> isar_proofs
wenzelm@50646
   226
      isar_shrink_factor ~> isar_shrink
wenzelm@50646
   227
      max_relevant ~> max_facts
wenzelm@50646
   228
      relevance_thresholds ~> fact_thresholds
wenzelm@50646
   229
wenzelm@50646
   230
* Quickcheck: added an optimisation for equality premises.  It is
wenzelm@50646
   231
switched on by default, and can be switched off by setting the
wenzelm@50646
   232
configuration quickcheck_optimise_equality to false.
wenzelm@50646
   233
kuncar@50878
   234
* Quotient: only one quotient can be defined by quotient_type
kuncar@50878
   235
INCOMPATIBILITY.
kuncar@50878
   236
kuncar@50878
   237
* Lifting:
kuncar@50878
   238
  - generation of an abstraction function equation in lift_definition
kuncar@50878
   239
  - quot_del attribute
kuncar@50878
   240
  - renamed no_abs_code -> no_code (INCOMPATIBILITY.)
kuncar@50878
   241
wenzelm@50646
   242
* Simproc "finite_Collect" rewrites set comprehensions into pointfree
wenzelm@50646
   243
expressions.
wenzelm@50646
   244
wenzelm@50646
   245
* Preprocessing of the code generator rewrites set comprehensions into
wenzelm@50646
   246
pointfree expressions.
wenzelm@50646
   247
wenzelm@50646
   248
* The SMT solver Z3 has now by default a restricted set of directly
wenzelm@50646
   249
supported features. For the full set of features (div/mod, nonlinear
wenzelm@50646
   250
arithmetic, datatypes/records) with potential proof reconstruction
wenzelm@50646
   251
failures, enable the configuration option "z3_with_extensions".  Minor
wenzelm@50646
   252
INCOMPATIBILITY.
haftmann@49948
   253
wenzelm@49836
   254
* Simplified 'typedef' specifications: historical options for implicit
wenzelm@49836
   255
set definition and alternative name have been discontinued.  The
wenzelm@49836
   256
former behavior of "typedef (open) t = A" is now the default, but
wenzelm@49836
   257
written just "typedef t = A".  INCOMPATIBILITY, need to adapt theories
wenzelm@49836
   258
accordingly.
wenzelm@49836
   259
wenzelm@50646
   260
* Removed constant "chars"; prefer "Enum.enum" on type "char"
wenzelm@50646
   261
directly.  INCOMPATIBILITY.
wenzelm@50646
   262
wenzelm@50646
   263
* Moved operation product, sublists and n_lists from theory Enum to
wenzelm@50646
   264
List.  INCOMPATIBILITY.
haftmann@49822
   265
haftmann@49739
   266
* Theorem UN_o generalized to SUP_comp.  INCOMPATIBILITY.
haftmann@49739
   267
haftmann@49738
   268
* Class "comm_monoid_diff" formalises properties of bounded
haftmann@49388
   269
subtraction, with natural numbers and multisets as typical instances.
haftmann@49388
   270
wenzelm@50646
   271
* Added combinator "Option.these" with type "'a option set => 'a set".
wenzelm@50646
   272
wenzelm@50646
   273
* Theory "Transitive_Closure": renamed lemmas
wenzelm@50646
   274
wenzelm@50646
   275
  reflcl_tranclp -> reflclp_tranclp
wenzelm@50646
   276
  rtranclp_reflcl -> rtranclp_reflclp
wenzelm@50646
   277
wenzelm@50646
   278
INCOMPATIBILITY.
wenzelm@50646
   279
wenzelm@50646
   280
* Theory "Rings": renamed lemmas (in class semiring)
wenzelm@50646
   281
wenzelm@50646

wenzelm@50646
   287
* Generalized the definition of limits:
wenzelm@50646
   288
wenzelm@50646
   289
  - Introduced the predicate filterlim (LIM x F. f x :> G) which
wenzelm@50646
   290
    expresses that when the input values x converge to F then the
wenzelm@50646
   291
    output f x converges to G.
wenzelm@50646
   292
wenzelm@50646
   293
  - Added filters for convergence to positive (at_top) and negative
wenzelm@50646
   294
    infinity (at_bot).
wenzelm@50646
   295
wenzelm@50646
   296
  - Moved infinity in the norm (at_infinity) from
wenzelm@50646
   297
    Multivariate_Analysis to Complex_Main.
wenzelm@50646
   298
wenzelm@50646
   299
  - Removed real_tendsto_inf, it is superseded by "LIM x F. f x :>
wenzelm@50646
   300
    at_top".

wenzelm@50646
   303
wenzelm@50646
   304
* Theory "Library/Option_ord" provides instantiation of option type to
wenzelm@50646
   305
lattice type classes.
wenzelm@50646
   306
wenzelm@50646
   307
* Theory "Library/Multiset": renamed
wenzelm@50646

wenzelm@50646
   313
wenzelm@50646
   314
* Renamed theory Library/List_Prefix to Library/Sublist, with related
wenzelm@50646
   315
changes as follows.
wenzelm@50646
   316
wenzelm@50646
   317
  - Renamed constants (and related lemmas)

      prefix ~> prefixeq
Christian@49145
   320
      strict_prefix ~> prefix
Christian@49145
   321
wenzelm@50646
   322
  - Replaced constant "postfix" by "suffixeq" with swapped argument
wenzelm@50646
   323
    order (i.e., "postfix xs ys" is now "suffixeq ys xs") and dropped
wenzelm@50646
   324
    old infix syntax "xs >>= ys"; use "suffixeq ys xs" instead.
wenzelm@50646
   325
    Renamed lemmas accordingly.
wenzelm@50646
   326
wenzelm@50646
   327
  - Added constant "list_hembeq" for homeomorphic embedding on
wenzelm@50646
   328
    lists. Added abbreviation "sublisteq" for special case
wenzelm@50646
   329
    "list_hembeq (op =)".
wenzelm@50646
   330
wenzelm@50646
   331
  - Theory Library/Sublist no longer provides "order" and "bot" type
wenzelm@50646
   332
    class instances for the prefix order (merely corresponding locale
wenzelm@50646
   333
    interpretations). The type class instances are now in theory
wenzelm@50646
   334
    Library/Prefix_Order.
wenzelm@50646
   335
wenzelm@50646
   336
  - The sublist relation of theory Library/Sublist_Order is now based
wenzelm@50646
   337
    on "Sublist.sublisteq".  Renamed lemmas accordingly:

wenzelm@50646
   357
wenzelm@50646
   358
* New theory Library/Countable_Set.

wenzelm@50646
   360
* Theory Library/Debug and Library/Parallel provide debugging and

   361
parallel execution for code generated towards Isabelle/ML.
wenzelm@50646
   362
wenzelm@50646
   363
* Theory Library/FuncSet: Extended support for Pi and extensional and
wenzelm@50646
   364
introduce the extensional dependent function space "PiE". Replaced
wenzelm@50646
   365
extensional_funcset by an abbreviation, and renamed lemmas from
wenzelm@50646
   366
extensional_funcset to PiE as follows:

   383
Data").
wenzelm@50646
   384
wenzelm@50646
   385
* Theory Library/Phantom: generic phantom type to make a type
wenzelm@50646
   386
parameter appear in a constant's type.  This alternative to adding
wenzelm@50646
   387
TYPE('a) as another parameter avoids unnecessary closures in generated
wenzelm@50646
   388
code.
wenzelm@50646
   389
wenzelm@50646
   390
* Theory Library/RBT_Impl: efficient construction of red-black trees
wenzelm@50646
   391
from sorted associative lists. Merging two trees with rbt_union may
wenzelm@50646
   392
return a structurally different tree than before.  Potential

wenzelm@50646
   405
vectors from the Basis set: "\<Chi>\<Chi> i. f i" is superseded by
wenzelm@50646
   406
"SUM i : Basis. f i * r i".
wenzelm@50646
   407
wenzelm@50646
   408
  With this change the following constants are also changed or removed:
wenzelm@50646
   409
wenzelm@50646
   410
    DIM('a) :: nat  ~>  card (Basis :: 'a set)   (is an abbreviation)

   411
    a $$ i  ~>  inner a i  (where i : Basis)
wenzelm@50646
   412
    cart_base i  removed
wenzelm@50646
   413
    \<pi>, \<pi>'  removed
hoelzl@50526

   415
  Theorems about these constants where removed.
hoelzl@50526

   432
* HOL/Probability:
wenzelm@50646
   433
wenzelm@50646
   434
  - Added simproc "measurable" to automatically prove measurability.
wenzelm@50646
   435
wenzelm@50646
   436
  - Added induction rules for sigma sets with disjoint union
wenzelm@50646
   437
    (sigma_sets_induct_disjoint) and for Borel-measurable functions
wenzelm@50646
   438
    (borel_measurable_induct).
wenzelm@50646
   439
wenzelm@50646
   440
  - Added the Daniell-Kolmogorov theorem (the existence the limit of a
wenzelm@50646
   441
    projective family).
wenzelm@50646
   442
wenzelm@50646

AFP entry "Ordinals_and_Cardinals").
wenzelm@50646
   445
wenzelm@50646
   446
* HOL/BNF: New (co)datatype package based on bounded natural functors
wenzelm@50646
   447
with support for mixed, nested recursion and interesting non-free
wenzelm@50646
   448
datatypes.
blanchet@48094
   449
wenzelm@50991
   450
* HOL/Finite_Set and Relation: added new set and relation operations
kuncar@50878
   451
expressed by Finite_Set.fold.
kuncar@50878
   452
kuncar@50878
   453

kuncar@50878
   454
trees for the code generator.
kuncar@50878
   455
kuncar@50878
   456
* HOL/Library/RBT and HOL/Library/Mapping have been converted to
kuncar@50878

Lifting/Transfer.
kuncar@50878
   458
possible INCOMPATIBILITY.
kuncar@50878

*** Document preparation ***
wenzelm@48206
   465
wenzelm@50646
   466
* Dropped legacy antiquotations "term_style" and "thm_style", since
wenzelm@50646
   467
styles may be given as arguments to "term" and "thm" already.
wenzelm@50646
   468
Discontinued legacy styles "prem1" .. "prem19".
wenzelm@50646
   469
wenzelm@50646
   470
* Default LaTeX rendering for \<euro> is now based on eurosym package,
wenzelm@50646
   471
instead of slightly exotic babel/greek.
wenzelm@48206
   472
wenzelm@48616
   473
* Document variant NAME may use different LaTeX entry point
wenzelm@48616
   474
document/root_NAME.tex if that file exists, instead of the common
wenzelm@48616
   475
document/root.tex.
wenzelm@48616
   476
wenzelm@48657
   477
* Simplified custom document/build script, instead of old-style
wenzelm@48657
   478
document/IsaMakefile.  Minor INCOMPATIBILITY.
wenzelm@48657

wenzelm@48992
   481
*** ML ***
wenzelm@48992
   482
wenzelm@50646
   483
* The default limit for maximum number of worker threads is now 8,
wenzelm@50646
   484
instead of 4, in correspondence to capabilities of contemporary
wenzelm@50646
   485
hardware and Poly/ML runtime system.
wenzelm@50646
   486
wenzelm@49869
   487
* Type Seq.results and related operations support embedded error
wenzelm@49869
   488
messages within lazy enumerations, and thus allow to provide
wenzelm@49869
   489
informative errors in the absence of any usable results.
wenzelm@49869
   490
wenzelm@48992
   491
* Renamed Position.str_of to Position.here to emphasize that this is a
wenzelm@48992
   492
formal device to inline positions into message text, but not
wenzelm@48992
   493
necessarily printing visible text.

*** System ***
wenzelm@48206
   497
wenzelm@48585
   498
* Advanced support for Isabelle sessions and build management, see
wenzelm@48585
   499
"system" manual for the chapter of that name, especially the "isabelle
wenzelm@51056
   500
build" tool and its examples.  The "isabelle mkroot" tool prepares
wenzelm@51056
   501
session root directories for use with "isabelle build", similar to
wenzelm@51056
   502
former "isabelle mkdir" for "isabelle usedir".  Note that this affects
wenzelm@51056
   503
document preparation as well.  INCOMPATIBILITY, isabelle usedir /
wenzelm@48736
   504
mkdir / make are rendered obsolete.
wenzelm@48736
   505
wenzelm@51056
   506
* Discontinued obsolete Isabelle/build script, it is superseded by the
wenzelm@51056
   507
regular isabelle build tool.  For example:
wenzelm@51056
   508
wenzelm@51056
   509
  isabelle build -s -b HOL
wenzelm@51056
   510
wenzelm@48736
   511
* Discontinued obsolete "isabelle makeall".
wenzelm@48585
   512
wenzelm@48722
   513
* Discontinued obsolete IsaMakefile and ROOT.ML files from the
wenzelm@48722
   514
Isabelle distribution, except for rudimentary src/HOL/IsaMakefile that
wenzelm@48722
   515
provides some traditional targets that invoke "isabelle build".  Note
wenzelm@48722
   516
that this is inefficient!  Applications of Isabelle/HOL involving
wenzelm@48722
   517
"isabelle make" should be upgraded to use "isabelle build" directly.
wenzelm@48722
   518
wenzelm@48693
   519
* The "isabelle options" tool prints Isabelle system options, as
wenzelm@48693
   520
required for "isabelle build", for example.
wenzelm@48693
   521
wenzelm@50646
   522
* The "isabelle logo" tool produces EPS and PDF format simultaneously.
wenzelm@50646
   523
Minor INCOMPATIBILITY in command-line options.
wenzelm@50646
   524
wenzelm@50646
   525
* The "isabelle install" tool has now a simpler command-line.  Minor
wenzelm@50646
   526
INCOMPATIBILITY.
wenzelm@50646
   527
wenzelm@48844
   528
* The "isabelle components" tool helps to resolve add-on components
wenzelm@48844
   529
that are not bundled, or referenced from a bare-bones repository
wenzelm@48844
   530
version of Isabelle.
wenzelm@48844
   531
wenzelm@50646
   532
* Settings variable ISABELLE_PLATFORM_FAMILY refers to the general
wenzelm@50646
   533
platform family: "linux", "macos", "windows".
wenzelm@50646
   534
wenzelm@50646
   535
* The ML system is configured as regular component, and no longer
wenzelm@50646
   536
picked up from some surrounding directory.  Potential INCOMPATIBILITY
wenzelm@50646
   537
for home-made settings.
wenzelm@50132
   538
wenzelm@50701
   539
* Improved ML runtime statistics (heap, threads, future tasks etc.).
wenzelm@50701
   540
wenzelm@48206
   541
* Discontinued support for Poly/ML 5.2.1, which was the last version
wenzelm@48206
   542
without exception positions and advanced ML compiler/toplevel
wenzelm@48206
   543
configuration.
wenzelm@48206
   544
wenzelm@48574
   545
* Discontinued special treatment of Proof General -- no longer guess
wenzelm@48574
   546
PROOFGENERAL_HOME based on accidental file-system layout.  Minor
wenzelm@48574
   547
INCOMPATIBILITY: provide PROOFGENERAL_HOME and PROOFGENERAL_OPTIONS
wenzelm@48574
   548
settings manually, or use a Proof General version that has been
wenzelm@48574
   549
bundled as Isabelle component.

* Prover IDE (PIDE) improvements:
wenzelm@45614
   559
wenzelm@47585
   560
  - more robust Sledgehammer integration (as before the sledgehammer
wenzelm@47806
   561
    command-line needs to be typed into the source buffer)
wenzelm@45614
   562
  - markup for bound variables
wenzelm@47806
   563
  - markup for types of term variables (displayed as tooltips)
wenzelm@46956
   564
  - support for user-defined Isar commands within the running session
wenzelm@47158
   565
  - improved support for Unicode outside original 16bit range
wenzelm@47158
   566
    e.g. glyph for \<A> (thanks to jEdit 4.5.1)
wenzelm@45614
   567
wenzelm@47806
   568
* Forward declaration of outer syntax keywords within the theory
wenzelm@47806
   569
header -- minor INCOMPATIBILITY for user-defined commands.  Allow new
wenzelm@47806
   570
commands to be used in the same theory where defined.
wenzelm@46485
   571
wenzelm@47482
   572
* Auxiliary contexts indicate block structure for specifications with
wenzelm@47482
   573
additional parameters and assumptions.  Such unnamed contexts may be
wenzelm@47482
   574
nested within other targets, like 'theory', 'locale', 'class',
wenzelm@47482
   575
'instantiation' etc.  Results from the local context are generalized
wenzelm@47482
   576
accordingly and applied to the enclosing target context.  Example:
wenzelm@47482
   577
wenzelm@47482
   578
  context
wenzelm@47482
   579
    fixes x y z :: 'a
wenzelm@47482
   580
    assumes xy: "x = y" and yz: "y = z"
wenzelm@47482
   581
  begin
wenzelm@47482
   582
wenzelm@47482
   583
  lemma my_trans: "x = z" using xy yz by simp
wenzelm@47482
   584
wenzelm@47482
   585
  end
wenzelm@47482
   586
wenzelm@47482
   587
  thm my_trans
wenzelm@47482
   588
wenzelm@47482
   589
The most basic application is to factor-out context elements of
wenzelm@47482
   590
several fixes/assumes/shows theorem statements, e.g. see
wenzelm@47482
   591
~~/src/HOL/Isar_Examples/Group_Context.thy
wenzelm@47482
   592
wenzelm@47482
   593
Any other local theory specification element works within the "context
wenzelm@47482
   594
... begin ... end" block as well.
wenzelm@47482
   595
wenzelm@47484
   596
* Bundled declarations associate attributed fact expressions with a
wenzelm@47484
   597
given name in the context.  These may be later included in other
wenzelm@47484
   598
contexts.  This allows to manage context extensions casually, without
wenzelm@47855
   599
the logical dependencies of locales and locale interpretation.  See
wenzelm@47855
   600
commands 'bundle', 'include', 'including' etc. in the isar-ref manual.
wenzelm@47484
   601
wenzelm@47829
   602
* Commands 'lemmas' and 'theorems' allow local variables using 'for'
wenzelm@47829
   603
declaration, and results are standardized before being stored.  Thus
wenzelm@47829
   604
old-style "standard" after instantiation or composition of facts
wenzelm@47829
   605
becomes obsolete.  Minor INCOMPATIBILITY, due to potential change of
wenzelm@47829
   606
indices of schematic variables.
wenzelm@47829
   607
wenzelm@47829
   608
* Rule attributes in local theory declarations (e.g. locale or class)
wenzelm@47829
   609
are now statically evaluated: the resulting theorem is stored instead
wenzelm@47829
   610
of the original expression.  INCOMPATIBILITY in rare situations, where
wenzelm@47829
   611
the historic accident of dynamic re-evaluation in interpretations
wenzelm@47829
   612
etc. was exploited.
wenzelm@47829
   613
wenzelm@47829
   614
* New tutorial "Programming and Proving in Isabelle/HOL"
wenzelm@47829
   615
("prog-prove").  It completely supersedes "A Tutorial Introduction to
wenzelm@47829
   616
Structured Isar Proofs" ("isar-overview"), which has been removed.  It
wenzelm@47829
   617
also supersedes "Isabelle/HOL, A Proof Assistant for Higher-Order
wenzelm@47829
   618
Logic" as the recommended beginners tutorial, but does not cover all
wenzelm@47829
   619
of the material of that old tutorial.
wenzelm@47829
   620
wenzelm@47829
   621
* Updated and extended reference manuals: "isar-ref",
wenzelm@47829
   622
"implementation", "system"; reduced remaining material in old "ref"
wenzelm@47829
   623
manual.
wenzelm@47829

wenzelm@47829
   625
wenzelm@47829
   626
*** Pure ***
wenzelm@47829
   627
wenzelm@46976
   628
* Command 'definition' no longer exports the foundational "raw_def"
wenzelm@46976
   629
into the user context.  Minor INCOMPATIBILITY, may use the regular
wenzelm@46976
   630
"def" result with attribute "abs_def" to imitate the old version.
wenzelm@46976
   631
wenzelm@47855
   632
* Attribute "abs_def" turns an equation of the form "f x y == t" into
wenzelm@47855
   633
"f == %x y. t", which ensures that "simp" or "unfold" steps always
wenzelm@47855
   634
expand it.  This also works for object-logic equality.  (Formerly
wenzelm@47855
   635
undocumented feature.)
wenzelm@47855
   636
wenzelm@47856
   637
* Sort constraints are now propagated in simultaneous statements, just
wenzelm@47856
   638
like type constraints.  INCOMPATIBILITY in rare situations, where
wenzelm@47856
   639
distinct sorts used to be assigned accidentally.  For example:
wenzelm@47856
   640
wenzelm@47856
   641
  lemma "P (x::'a::foo)" and "Q (y::'a::bar)"  -- "now illegal"
wenzelm@47856
   642
wenzelm@47856
   643
  lemma "P (x::'a)" and "Q (y::'a::bar)"
wenzelm@47856
   644
    -- "now uniform 'a::bar instead of default sort for first occurrence (!)"
wenzelm@47856
   645
wenzelm@47856
   646
* Rule composition via attribute "OF" (or ML functions OF/MRS) is more
wenzelm@47856
   647
tolerant against multiple unifiers, as long as the final result is
wenzelm@47856
   648
unique.  (As before, rules are composed in canonical right-to-left
wenzelm@47856
   649
order to accommodate newly introduced premises.)
wenzelm@47856
   650
wenzelm@47806
   651
* Renamed some inner syntax categories:
wenzelm@47806
   652
wenzelm@47806
   653
    num ~> num_token
wenzelm@47806
   654
    xnum ~> xnum_token
wenzelm@47806
   655
    xstr ~> str_token
wenzelm@47806
   656
wenzelm@47806
   657
Minor INCOMPATIBILITY.  Note that in practice "num_const" or
wenzelm@47806
   658
"num_position" etc. are mainly used instead (which also include
wenzelm@47806
   659
position information via constraints).
wenzelm@47806
   660
wenzelm@47829
   661
* Simplified configuration options for syntax ambiguity: see
wenzelm@47829
   662
"syntax_ambiguity_warning" and "syntax_ambiguity_limit" in isar-ref
wenzelm@47829
   663
manual.  Minor INCOMPATIBILITY.
wenzelm@47829
   664
wenzelm@47856
   665
* Discontinued configuration option "syntax_positions": atomic terms
wenzelm@47856
   666
in parse trees are always annotated by position constraints.
wenzelm@45134
   667
wenzelm@47464
   668
* Old code generator for SML and its commands 'code_module',
wenzelm@45383
   669
'code_library', 'consts_code', 'types_code' have been discontinued.
haftmann@46028
   670
Use commands of the generic code generator instead.  INCOMPATIBILITY.
wenzelm@45383
   671
wenzelm@47464
   672
* Redundant attribute "code_inline" has been discontinued. Use
wenzelm@47464
   673
"code_unfold" instead.  INCOMPATIBILITY.
wenzelm@47464
   674
wenzelm@47464
   675
* Dropped attribute "code_unfold_post" in favor of the its dual
wenzelm@47464
   676
"code_abbrev", which yields a common pattern in definitions like
haftmann@46028
   677
haftmann@46028
   678
  definition [code_abbrev]: "f = t"
haftmann@46028
   679
haftmann@46028
   680
INCOMPATIBILITY.
wenzelm@45383
   681
wenzelm@47856
   682
* Obsolete 'types' command has been discontinued.  Use 'type_synonym'
wenzelm@47856
   683
instead.  INCOMPATIBILITY.
wenzelm@47856
   684
wenzelm@47856
   685
* Discontinued old "prems" fact, which used to refer to the accidental
wenzelm@47856
   686
collection of foundational premises in the context (already marked as
wenzelm@47856
   687
legacy since Isabelle2011).

   692
* Type 'a set is now a proper type constructor (just as before
wenzelm@47464
   693
Isabelle2008).  Definitions mem_def and Collect_def have disappeared.
wenzelm@47464
   694
Non-trivial INCOMPATIBILITY.  For developments keeping predicates and
wenzelm@47855
   695
sets separate, it is often sufficient to rephrase some set S that has
wenzelm@47855
   696
been accidentally used as predicates by "%x. x : S", and some
wenzelm@47855
   697
predicate P that has been accidentally used as set by "{x. P x}".
wenzelm@47855
   698
Corresponding proofs in a first step should be pruned from any
wenzelm@47855
   699
tinkering with former theorems mem_def and Collect_def as far as
wenzelm@47855
   700
possible.
wenzelm@47855
   701
wenzelm@47855
   702
For developments which deliberately mix predicates and sets, a
wenzelm@47464
   703
planning step is necessary to determine what should become a predicate
wenzelm@47464
   704
and what a set.  It can be helpful to carry out that step in
wenzelm@47464
   705
Isabelle2011-1 before jumping right into the current release.
wenzelm@47464
   706
wenzelm@47855
   707
* Code generation by default implements sets as container type rather
wenzelm@47855
   708
than predicates.  INCOMPATIBILITY.
wenzelm@47855
   709
wenzelm@47855
   710
* New type synonym 'a rel = ('a * 'a) set
wenzelm@47855
   711
wenzelm@47464
   712
* The representation of numerals has changed.  Datatype "num"
wenzelm@47464
   713
represents strictly positive binary numerals, along with functions
wenzelm@47464
   714
"numeral :: num => 'a" and "neg_numeral :: num => 'a" to represent
wenzelm@47855
   715
positive and negated numeric literals, respectively.  See also
wenzelm@47855
   716
definitions in ~~/src/HOL/Num.thy.  Potential INCOMPATIBILITY, some
wenzelm@47855
   717
user theories may require adaptations as follows:
huffman@47108
   718
huffman@47108
   719
  - Theorems with number_ring or number_semiring constraints: These
huffman@47108
   720
    classes are gone; use comm_ring_1 or comm_semiring_1 instead.
huffman@47108
   721
huffman@47108
   722
  - Theories defining numeric types: Remove number, number_semiring,
huffman@47108
   723
    and number_ring instances. Defer all theorems about numerals until
huffman@47108
   724
    after classes one and semigroup_add have been instantiated.
huffman@47108
   725
huffman@47108
   726
  - Numeral-only simp rules: Replace each rule having a "number_of v"
huffman@47108
   727
    pattern with two copies, one for numeral and one for neg_numeral.
huffman@47108
   728
huffman@47108
   729
  - Theorems about subclasses of semiring_1 or ring_1: These classes
huffman@47108
   730
    automatically support numerals now, so more simp rules and
huffman@47108
   731
    simprocs may now apply within the proof.
huffman@47108
   732
huffman@47108
   733
  - Definitions and theorems using old constructors Pls/Min/Bit0/Bit1:
huffman@47108
   734
    Redefine using other integer operations.
huffman@47108
   735
wenzelm@47855
   736
* Transfer: New package intended to generalize the existing
wenzelm@47855
   737
"descending" method and related theorem attributes from the Quotient
wenzelm@47855
   738
package.  (Not all functionality is implemented yet, but future
wenzelm@47855
   739
development will focus on Transfer as an eventual replacement for the
wenzelm@47855
   740
corresponding parts of the Quotient package.)
wenzelm@47809
   741
wenzelm@47809
   742
  - transfer_rule attribute: Maintains a collection of transfer rules,
wenzelm@47809
   743
    which relate constants at two different types. Transfer rules may
wenzelm@47809
   744
    relate different type instances of the same polymorphic constant,
wenzelm@47809
   745
    or they may relate an operation on a raw type to a corresponding
wenzelm@47809
   746
    operation on an abstract type (quotient or subtype). For example:
wenzelm@47809
   747
wenzelm@47809
   748
    ((A ===> B) ===> list_all2 A ===> list_all2 B) map map
wenzelm@47809
   749
    (cr_int ===> cr_int ===> cr_int) (%(x,y) (u,v). (x+u, y+v)) plus_int
wenzelm@47809
   750
wenzelm@47809
   751
  - transfer method: Replaces a subgoal on abstract types with an
wenzelm@47809
   752
    equivalent subgoal on the corresponding raw types. Constants are
wenzelm@47809
   753
    replaced with corresponding ones according to the transfer rules.
wenzelm@47809
   754
    Goals are generalized over all free variables by default; this is
huffman@47851
   755
    necessary for variables whose types change, but can be overridden
wenzelm@47855
   756
    for specific variables with e.g. "transfer fixing: x y z".  The
wenzelm@47809
   757
    variant transfer' method allows replacing a subgoal with one that
wenzelm@47809
   758
    is logically stronger (rather than equivalent).
wenzelm@47809
   759
wenzelm@47809
   760
  - relator_eq attribute: Collects identity laws for relators of
wenzelm@47809
   761
    various type constructors, e.g. "list_all2 (op =) = (op =)".  The
wenzelm@47809
   762
    transfer method uses these lemmas to infer transfer rules for
wenzelm@47809
   763
    non-polymorphic constants on the fly.
wenzelm@47809
   764
wenzelm@47809
   765
  - transfer_prover method: Assists with proving a transfer rule for a
wenzelm@47809
   766
    new constant, provided the constant is defined in terms of other
wenzelm@47809
   767
    constants that already have transfer rules. It should be applied
wenzelm@47809
   768
    after unfolding the constant definitions.
wenzelm@47809

wenzelm@47809
   771
    from type nat to type int.
wenzelm@47809
   772
huffman@47851
   773
* Lifting: New package intended to generalize the quotient_definition
huffman@47851
   774
facility of the Quotient package; designed to work with Transfer.
wenzelm@47809
   775
wenzelm@47809
   776
  - lift_definition command: Defines operations on an abstract type in
wenzelm@47809
   777
    terms of a corresponding operation on a representation
wenzelm@47809
   778
    type.  Example syntax:
wenzelm@47809
   779
wenzelm@47809
   780
    lift_definition dlist_insert :: "'a => 'a dlist => 'a dlist"
wenzelm@47809
   781
      is List.insert
wenzelm@47809
   782
wenzelm@47809
   783
    Users must discharge a respectfulness proof obligation when each
wenzelm@47809
   784
    constant is defined. (For a type copy, i.e. a typedef with UNIV,
wenzelm@47809
   785
    the proof is discharged automatically.) The obligation is
wenzelm@47809
   786
    presented in a user-friendly, readable form; a respectfulness
wenzelm@47809
   787
    theorem in the standard format and a transfer rule are generated
wenzelm@47809
   788
    by the package.
wenzelm@47809
   789
wenzelm@47809
   790
  - Integration with code_abstype: For typedefs (e.g. subtypes
wenzelm@47809
   791
    corresponding to a datatype invariant, such as dlist),
wenzelm@47809
   792
    lift_definition generates a code certificate theorem and sets up
wenzelm@47809
   793
    code generation for each constant.
wenzelm@47809
   794
wenzelm@47809
   795
  - setup_lifting command: Sets up the Lifting package to work with a
wenzelm@47809
   796
    user-defined type. The user must provide either a quotient theorem
wenzelm@47809
   797
    or a type_definition theorem.  The package configures transfer
wenzelm@47809
   798
    rules for equality and quantifiers on the type, and sets up the
wenzelm@47809
   799
    lift_definition command to work with the type.
wenzelm@47809
   800
wenzelm@47809
   801
  - Usage examples: See Quotient_Examples/Lift_DList.thy,
huffman@47851
   802
    Quotient_Examples/Lift_RBT.thy, Quotient_Examples/Lift_FSet.thy,
huffman@47851
   803
    Word/Word.thy and Library/Float.thy.
wenzelm@47809
   804
wenzelm@47809
   805
* Quotient package:
wenzelm@47809
   806
wenzelm@47809
   807
  - The 'quotient_type' command now supports a 'morphisms' option with
wenzelm@47809
   808
    rep and abs functions, similar to typedef.
wenzelm@47809
   809
wenzelm@47809
   810
  - 'quotient_type' sets up new types to work with the Lifting and
wenzelm@47809
   811
    Transfer packages, as with 'setup_lifting'.
wenzelm@47809
   812
wenzelm@47809
   813
  - The 'quotient_definition' command now requires the user to prove a
wenzelm@47809
   814
    respectfulness property at the point where the constant is
wenzelm@47809
   815
    defined, similar to lift_definition; INCOMPATIBILITY.
wenzelm@47809
   816
wenzelm@47809
   817
  - Renamed predicate 'Quotient' to 'Quotient3', and renamed theorems
wenzelm@47809
   818
    accordingly, INCOMPATIBILITY.
wenzelm@47809
   819
wenzelm@47809
   820
* New diagnostic command 'find_unused_assms' to find potentially
wenzelm@47809
   821
superfluous assumptions in theorems using Quickcheck.
wenzelm@47809
   822
wenzelm@47809
   823
* Quickcheck:
wenzelm@47809

  - Quickcheck returns variable assignments as counterexamples, which
wenzelm@47809
   826
    allows to reveal the underspecification of functions under test.
wenzelm@47809
   827
    For example, refuting "hd xs = x", it presents the variable
wenzelm@47809
   828
    assignment xs = [] and x = a1 as a counterexample, assuming that
wenzelm@47809
   829
    any property is false whenever "hd []" occurs in it.
wenzelm@47809
   830
wenzelm@47809
   831
    These counterexample are marked as potentially spurious, as
wenzelm@47809
   832
    Quickcheck also returns "xs = []" as a counterexample to the
wenzelm@47809
   833
    obvious theorem "hd xs = hd xs".
wenzelm@47809
   834
wenzelm@47809
   835
    After finding a potentially spurious counterexample, Quickcheck
wenzelm@47809
   836
    continues searching for genuine ones.
wenzelm@47809
   837
wenzelm@47809
   838
    By default, Quickcheck shows potentially spurious and genuine
wenzelm@47809
   839
    counterexamples. The option "genuine_only" sets quickcheck to only
wenzelm@47809
   840
    show genuine counterexamples.
wenzelm@47809
   841
wenzelm@47809
   842
  - The command 'quickcheck_generator' creates random and exhaustive
wenzelm@47809
   843
    value generators for a given type and operations.
wenzelm@47809
   844
wenzelm@47809
   845
    It generates values by using the operations as if they were
wenzelm@47809
   846
    constructors of that type.
wenzelm@47809
   847
wenzelm@47809
   848
  - Support for multisets.
wenzelm@47809
   849
wenzelm@47809
   850
  - Added "use_subtype" options.
wenzelm@47809
   851
wenzelm@47809
   852
  - Added "quickcheck_locale" configuration to specify how to process
wenzelm@47809
   853
    conjectures in a locale context.
wenzelm@47809
   854
wenzelm@47855
   855
* Nitpick: Fixed infinite loop caused by the 'peephole_optim' option
wenzelm@47855
   856
and affecting 'rat' and 'real'.
wenzelm@47809
   857
wenzelm@47809
   858
* Sledgehammer:
wenzelm@47809
   859
  - Integrated more tightly with SPASS, as described in the ITP 2012
wenzelm@47809
   860
    paper "More SPASS with Isabelle".
wenzelm@47809
   861
  - Made it try "smt" as a fallback if "metis" fails or times out.
wenzelm@47809
   862
  - Added support for the following provers: Alt-Ergo (via Why3 and
wenzelm@47809
   863
    TFF1), iProver, iProver-Eq.
wenzelm@47809
   864
  - Sped up the minimizer.
wenzelm@47809
   865
  - Added "lam_trans", "uncurry_aliases", and "minimize" options.
wenzelm@47809
   866
  - Renamed "slicing" ("no_slicing") option to "slice" ("dont_slice").
wenzelm@47809
   867
  - Renamed "sound" option to "strict".
wenzelm@47809
   868
wenzelm@47855
   869
* Metis: Added possibility to specify lambda translations scheme as a
wenzelm@47855
   870
parenthesized argument (e.g., "by (metis (lifting) ...)").
wenzelm@47855
   871
wenzelm@47855
   872
* SMT: Renamed "smt_fixed" option to "smt_read_only_certificates".
wenzelm@47855
   873
wenzelm@47855
   874
* Command 'try0': Renamed from 'try_methods'. INCOMPATIBILITY.
wenzelm@47809
   875
wenzelm@47856
   876
* New "case_product" attribute to generate a case rule doing multiple
wenzelm@47856
   877
case distinctions at the same time.  E.g.
wenzelm@47856
   878
wenzelm@47856
   879
  list.exhaust [case_product nat.exhaust]
wenzelm@47856
   880
wenzelm@47856
   881
produces a rule which can be used to perform case distinction on both
wenzelm@47856
   882
a list and a nat.
wenzelm@47856
   883
wenzelm@47809
   884
* New "eventually_elim" method as a generalized variant of the
wenzelm@47855
   885
eventually_elim* rules.  Supports structured proofs.
wenzelm@47855
   886
wenzelm@47702
   887
* Typedef with implicit set definition is considered legacy.  Use
wenzelm@47702
   888
"typedef (open)" form instead, which will eventually become the
wenzelm@47702
   889
default.
wenzelm@47702
   890
wenzelm@47856
   891
* Record: code generation can be switched off manually with
wenzelm@47856
   892
wenzelm@47856
   893
  declare [[record_coden = false]]  -- "default true"
wenzelm@47856
   894
wenzelm@47856
   895
* Datatype: type parameters allow explicit sort constraints.
wenzelm@47856
   896
wenzelm@47855
   897
* Concrete syntax for case expressions includes constraints for source
wenzelm@47855
   898
positions, and thus produces Prover IDE markup for its bindings.
wenzelm@47855
   899
INCOMPATIBILITY for old-style syntax translations that augment the
wenzelm@47855
   900
pattern notation; e.g. see src/HOL/HOLCF/One.thy for translations of
wenzelm@47855
   901
one_case.
wenzelm@47855
   902
wenzelm@47855
   903
* Clarified attribute "mono_set": pure declaration without modifying
wenzelm@47855
   904
the result of the fact expression.
wenzelm@47855
   905
haftmann@46752
   906
* More default pred/set conversions on a couple of relation operations
wenzelm@47464
   907
and predicates.  Added powers of predicate relations.  Consolidation
wenzelm@47464

* Session HOL-Word: New proof method "word_bitwise" for splitting
wenzelm@47809
  1360
machine word equalities and inequalities into logical circuits,
wenzelm@47809
  1361
defined in HOL/Word/WordBitwise.thy.  Supports addition, subtraction,
wenzelm@47809
  1362
multiplication, shifting by constants, bitwise operators and numeric
wenzelm@47809
  1363
constants.  Requires fixed-length word types, not 'a word.  Solves
wenzelm@47854
  1364
many standard word identities outright and converts more into first
wenzelm@47809
  1365
order problems amenable to blast or similar.  See also examples in

* Session HOL-Probability: Introduced the type "'a measure" to
wenzelm@47807
  1369
represent measures, this replaces the records 'a algebra and 'a
wenzelm@47807
  1370
measure_space.  The locales based on subset_class now have two
wenzelm@47856
  1371
locale-parameters the space \<Omega> and the set of measurable sets M.
wenzelm@47856
  1372
The product of probability spaces uses now the same constant as the
wenzelm@47856
  1373
finite product of sigma-finite measure spaces "PiM :: ('i => 'a)
wenzelm@47807
  1374
measure".  Most constants are defined now outside of locales and gain
wenzelm@47807
  1375
an additional parameter, like null_sets, almost_eventually or \<mu>'.
wenzelm@47807
  1376
Measure space constructions for distributions and densities now got
wenzelm@47807
  1377
their own constants distr and density.  Instead of using locales to
wenzelm@47807
  1378
describe measure spaces with a finite space, the measure count_space
wenzelm@47807
  1379
and point_measure is introduced.  INCOMPATIBILITY.

wenzelm@47463
  1555
* Much greater use of mathematical symbols.
wenzelm@47463
  1556
wenzelm@47463

  1562
* Antiquotation @{keyword "name"} produces a parser for outer syntax
wenzelm@46948
  1563
from a minor keyword introduced via theory header declaration.
wenzelm@46948
  1564
wenzelm@46961
  1565
* Antiquotation @{command_spec "name"} produces the
wenzelm@46961
  1566
Outer_Syntax.command_spec from a major keyword introduced via theory
wenzelm@46961
  1567
header declaration; it can be passed to Outer_Syntax.command etc.
wenzelm@46961
  1568
wenzelm@46916
  1569
* Local_Theory.define no longer hard-wires default theorem name
wenzelm@46992
  1570
"foo_def", but retains the binding as given.  If that is Binding.empty
wenzelm@46992
  1571
/ Attrib.empty_binding, the result is not registered as user-level
wenzelm@46992
  1572
fact.  The Local_Theory.define_internal variant allows to specify a
wenzelm@46992
  1573
non-empty name (used for the foundation in the background theory),
wenzelm@46992
  1574
while omitting the fact binding in the user-context.  Potential
wenzelm@46992
  1575
INCOMPATIBILITY for derived definitional packages: need to specify
wenzelm@46992
  1576
naming policy for primitive definitions more explicitly.
wenzelm@46916
  1577
wenzelm@46497
  1578
* Renamed Thm.capply to Thm.apply, and Thm.cabs to Thm.lambda in
wenzelm@46497
  1579
conformance with similar operations in structure Term and Logic.
wenzelm@46497
  1580
wenzelm@45592
  1581
* Antiquotation @{attributes [...]} embeds attribute source
wenzelm@45592
  1582
representation into the ML text, which is particularly useful with
wenzelm@45592
  1583
declarations like Local_Theory.note.
wenzelm@45592
  1584
wenzelm@45128
  1585
* Structure Proof_Context follows standard naming scheme.  Old

wenzelm@45128
  1587
wenzelm@45293
  1588
* Refined Local_Theory.declaration {syntax, pervasive}, with subtle
wenzelm@45298

* USER_HOME settings variable points to cross-platform user home
wenzelm@47661
  1611
directory, which coincides with HOME on POSIX systems only.  Likewise,
wenzelm@47661
  1612
the Isabelle path specification "~" now expands to $USER_HOME, instead
wenzelm@47661
  1613
of former $HOME.  A different default for USER_HOME may be set
wenzelm@47661
  1614
explicitly in shell environment, before Isabelle settings are
wenzelm@47661
  1615
evaluated.  Minor INCOMPATIBILITY: need to adapt Isabelle path where
wenzelm@47661
  1616
the generic user home was intended.
wenzelm@47661
  1617
wenzelm@47807
  1618
* ISABELLE_HOME_WINDOWS refers to ISABELLE_HOME in windows file name
wenzelm@47807
  1619
notation, which is useful for the jEdit file browser, for example.
wenzelm@47807
  1620

*** General ***
wenzelm@41703
  1630
wenzelm@44760
  1631
* Improved Isabelle/jEdit Prover IDE (PIDE), which can be invoked as
wenzelm@44968
  1632
"isabelle jedit" or "ISABELLE_HOME/Isabelle" on the command line.
wenzelm@44760
  1633
wenzelm@44777
  1634
  - Management of multiple theory files directly from the editor
wenzelm@44760
  1635
    buffer store -- bypassing the file-system (no requirement to save
wenzelm@44760
  1636
    files for checking).
wenzelm@44760
  1637
wenzelm@44777
  1638
  - Markup of formal entities within the text buffer, with semantic
wenzelm@44760
  1639
    highlighting, tooltips and hyperlinks to jump to defining source
wenzelm@44760
  1640
    positions.
wenzelm@44760
  1641
wenzelm@44777
  1642
  - Improved text rendering, with sub/superscripts in the source
wenzelm@44777
  1643
    buffer (including support for copy/paste wrt. output panel, HTML
wenzelm@44777
  1644
    theory output and other non-Isabelle text boxes).
wenzelm@44777
  1645
wenzelm@44777
  1646
  - Refined scheduling of proof checking and printing of results,
wenzelm@44760
  1647
    based on interactive editor view.  (Note: jEdit folding and
wenzelm@44760
  1648
    narrowing allows to restrict buffer perspectives explicitly.)
wenzelm@44760
  1649
wenzelm@44777
  1650
  - Reduced CPU performance requirements, usable on machines with few
wenzelm@44760
  1651
    cores.
wenzelm@44760
  1652
wenzelm@44777
  1653
  - Reduced memory requirements due to pruning of unused document
wenzelm@44760
  1654
    versions (garbage collection).
wenzelm@44760

  1657
including some remaining limitations.
wenzelm@44760
  1658
wenzelm@44800
  1659
* Theory loader: source files are exclusively located via the master
wenzelm@44800
  1660
directory of each theory node (where the .thy file itself resides).
wenzelm@44800
  1661
The global load path (such as src/HOL/Library) has been discontinued.
wenzelm@44800
  1662
Note that the path element ~~ may be used to reference theories in the
wenzelm@44800
  1663
Isabelle home folder -- for instance, "~~/src/HOL/Library/FuncSet".
wenzelm@44800
  1664
INCOMPATIBILITY.
wenzelm@44800
  1665
wenzelm@41955
  1666
* Theory loader: source files are identified by content via SHA1
wenzelm@41955
  1667
digests.  Discontinued former path/modtime identification and optional
wenzelm@41955
  1668
ISABELLE_FILE_IDENT plugin scripts.
wenzelm@41955
  1669
wenzelm@41703
  1670
* Parallelization of nested Isar proofs is subject to
wenzelm@41703
  1671
Goal.parallel_proofs_threshold (default 100).  See also isabelle
wenzelm@41703
  1672
usedir option -Q.
wenzelm@41703
  1673
wenzelm@42669
  1674
* Name space: former unsynchronized references are now proper
wenzelm@42669
  1675
configuration options, with more conventional names:
wenzelm@42669
  1676
wenzelm@42669
  1677
  long_names   ~> names_long
wenzelm@42669
  1678
  short_names  ~> names_short
wenzelm@42669
  1679
  unique_names ~> names_unique
wenzelm@42669
  1680
wenzelm@42669
  1681
Minor INCOMPATIBILITY, need to declare options in context like this:
wenzelm@42669
  1682
wenzelm@42669
  1683
  declare [[names_unique = false]]
wenzelm@42358
  1684
wenzelm@42502
  1685
* Literal facts `prop` may contain dummy patterns, e.g. `_ = _`.  Note
wenzelm@42502
  1686
that the result needs to be unique, which means fact specifications
wenzelm@42502
  1687
may have to be refined after enriching a proof context.
wenzelm@42502
  1688
wenzelm@44800
  1689
* Attribute "case_names" has been refined: the assumptions in each case
wenzelm@44800
  1690
can be named now by following the case name with [name1 name2 ...].
wenzelm@44800
  1691
wenzelm@44968
  1692
* Isabelle/Isar reference manual has been updated and extended:
wenzelm@44968
  1693
  - "Synopsis" provides a catalog of main Isar language concepts.
wenzelm@44968
  1694
  - Formal references in syntax diagrams, via @{rail} antiquotation.
wenzelm@44968
  1695
  - Updated material from classic "ref" manual, notably about
wenzelm@44968
  1696
    "Classical Reasoner".

* Theory Complex_Main: The definition of infinite series was
wenzelm@44967
  1884
generalized.  Now it is defined on the type class {topological_space,
wenzelm@44967
  1885
comm_monoid_add}.  Hence it is useable also for extended real numbers.
wenzelm@42484
  1886
huffman@44908
  1887
* Theory Complex_Main: The complex exponential function "expi" is now
huffman@44908
  1888
a type-constrained abbreviation for "exp :: complex => complex"; thus
huffman@44908
  1889
several polymorphic lemmas about "exp" are now applicable to "expi".
huffman@44908
  1890
wenzelm@44968
  1891
* Code generation:
wenzelm@44968
  1892
wenzelm@44968
  1893
  - Theory Library/Code_Char_ord provides native ordering of
wenzelm@44968
  1894
    characters in the target language.
wenzelm@44968
  1895
wenzelm@44968
  1896
  - Commands code_module and code_library are legacy, use export_code
wenzelm@44968
  1897
    instead.
wenzelm@44968
  1898
wenzelm@44968
  1899
  - Method "evaluation" is legacy, use method "eval" instead.
wenzelm@44968
  1900
wenzelm@44968
  1901
  - Legacy evaluator "SML" is deactivated by default.  May be
wenzelm@44968
  1902
    reactivated by the following theory command:
wenzelm@44968
  1903
wenzelm@44968
  1904
      setup {* Value.add_evaluator ("SML", Codegen.eval_term) *}
wenzelm@44968
  1905
wenzelm@44968
  1906
* Declare ext [intro] by default.  Rare INCOMPATIBILITY.
wenzelm@44968
  1907
wenzelm@45088
  1908
* New proof method "induction" that gives induction hypotheses the
wenzelm@45088
  1909
name "IH", thus distinguishing them from further hypotheses that come
wenzelm@45088
  1910
from rule induction.  The latter are still called "hyps".  Method
wenzelm@45088
  1911
"induction" is a thin wrapper around "induct" and follows the same
wenzelm@45088
  1912
syntax.
wenzelm@45088
  1913
wenzelm@44968
  1914
* Method "fastsimp" has been renamed to "fastforce", but "fastsimp" is
wenzelm@44968
  1915
still available as a legacy feature for some time.
wenzelm@44968
  1916
wenzelm@44968
  1917
* Nitpick:
wenzelm@44968
  1918
  - Added "need" and "total_consts" options.
wenzelm@44968
  1919
  - Reintroduced "show_skolems" option by popular demand.
wenzelm@44968
  1920
  - Renamed attribute: nitpick_def ~> nitpick_unfold.
wenzelm@44968
  1921
    INCOMPATIBILITY.
wenzelm@44968
  1922
wenzelm@44968
  1923
* Sledgehammer:
wenzelm@44968
  1924
  - Use quasi-sound (and efficient) translations by default.
wenzelm@44968
  1925
  - Added support for the following provers: E-ToFoF, LEO-II,
wenzelm@44968
  1926
    Satallax, SNARK, Waldmeister, and Z3 with TPTP syntax.
wenzelm@44968
  1927
  - Automatically preplay and minimize proofs before showing them if
wenzelm@44968
  1928
    this can be done within reasonable time.
wenzelm@44968
  1929
  - sledgehammer available_provers ~> sledgehammer supported_provers.
wenzelm@44968
  1930
    INCOMPATIBILITY.
wenzelm@44968
  1931
  - Added "preplay_timeout", "slicing", "type_enc", "sound",
wenzelm@44968
  1932
    "max_mono_iters", and "max_new_mono_instances" options.
wenzelm@44968
  1933
  - Removed "explicit_apply" and "full_types" options as well as "Full
wenzelm@44968
  1934
    Types" Proof General menu item. INCOMPATIBILITY.
wenzelm@44968
  1935
wenzelm@44968
  1936
* Metis:
wenzelm@44968
  1937
  - Removed "metisF" -- use "metis" instead. INCOMPATIBILITY.
wenzelm@44968
  1938
  - Obsoleted "metisFT" -- use "metis (full_types)" instead.
wenzelm@44968
  1939
    INCOMPATIBILITY.
wenzelm@44968
  1940
wenzelm@44968
  1941
* Command 'try':
wenzelm@44968
  1942
  - Renamed 'try_methods' and added "simp:", "intro:", "dest:", and
wenzelm@44968
  1943
    "elim:" options. INCOMPATIBILITY.
wenzelm@44968
  1944
  - Introduced 'try' that not only runs 'try_methods' but also
wenzelm@44968
  1945
    'solve_direct', 'sledgehammer', 'quickcheck', and 'nitpick'.
wenzelm@44968
  1946
wenzelm@44968
  1947
* Quickcheck:
wenzelm@44968
  1948
  - Added "eval" option to evaluate terms for the found counterexample
wenzelm@44968
  1949
    (currently only supported by the default (exhaustive) tester).
wenzelm@44968
  1950
  - Added post-processing of terms to obtain readable counterexamples
wenzelm@44968
  1951
    (currently only supported by the default (exhaustive) tester).
wenzelm@44968
  1952
  - New counterexample generator quickcheck[narrowing] enables
wenzelm@44968
  1953
    narrowing-based testing.  Requires the Glasgow Haskell compiler
wenzelm@44968
  1954
    with its installation location defined in the Isabelle settings
wenzelm@44968
  1955
    environment as ISABELLE_GHC.
wenzelm@44968
  1956
  - Removed quickcheck tester "SML" based on the SML code generator
wenzelm@44968
  1957
    (formly in HOL/Library).
wenzelm@44968
  1958
wenzelm@44968
  1959
* Function package: discontinued option "tailrec".  INCOMPATIBILITY,
wenzelm@44968
  1960
use 'partial_function' instead.
wenzelm@44968
  1961
wenzelm@44968
  1962
* Theory Library/Extended_Reals replaces now the positive extended
wenzelm@44968
  1963
reals found in probability theory. This file is extended by
wenzelm@44968
  1964
Multivariate_Analysis/Extended_Real_Limits.
wenzelm@44968
  1965
wenzelm@44974
  1966
* Theory Library/Old_Recdef: old 'recdef' package has been moved here,
wenzelm@44974
  1967
from where it must be imported explicitly if it is really required.
wenzelm@44974
  1968
INCOMPATIBILITY.
wenzelm@44968
  1969
wenzelm@44968
  1970
* Theory Library/Wfrec: well-founded recursion combinator "wfrec" has
wenzelm@44968
  1971
been moved here.  INCOMPATIBILITY.
wenzelm@44968
  1972
wenzelm@44968
  1973
* Theory Library/Saturated provides type of numbers with saturated
wenzelm@44968
  1974
arithmetic.
wenzelm@44968
  1975
wenzelm@44968
  1976
* Theory Library/Product_Lattice defines a pointwise ordering for the
wenzelm@44968
  1977
product type 'a * 'b, and provides instance proofs for various order
wenzelm@44968
  1978
and lattice type classes.
wenzelm@44968
  1979
wenzelm@44968
  1980
* Theory Library/Countable now provides the "countable_datatype" proof
wenzelm@44968
  1981
method for proving "countable" class instances for datatypes.
wenzelm@44968
  1982
wenzelm@44968
  1983
* Theory Library/Cset_Monad allows do notation for computable sets
wenzelm@44968
  1984
(cset) via the generic monad ad-hoc overloading facility.
wenzelm@44968
  1985
wenzelm@44968
  1986
* Library: Theories of common data structures are split into theories
wenzelm@44968
  1987
for implementation, an invariant-ensuring type, and connection to an
wenzelm@44968
  1988
abstract type. INCOMPATIBILITY.
wenzelm@44968
  1989
wenzelm@44968
  1990
  - RBT is split into RBT and RBT_Mapping.
wenzelm@44968
  1991
  - AssocList is split and renamed into AList and AList_Mapping.
wenzelm@44968
  1992
  - DList is split into DList_Impl, DList, and DList_Cset.
wenzelm@44968
  1993
  - Cset is split into Cset and List_Cset.
wenzelm@44968
  1994
wenzelm@44968
  1995
* Theory Library/Nat_Infinity has been renamed to
wenzelm@44968
  1996
Library/Extended_Nat, with name changes of the following types and
wenzelm@44968
  1997
constants:
wenzelm@44968
  1998
wenzelm@44968
  1999
  type inat   ~> type enat
wenzelm@44968
  2000
  Fin         ~> enat
wenzelm@44968
  2001
  Infty       ~> infinity (overloaded)

  2002
  iSuc        ~> eSuc
wenzelm@44968
  2003
  the_Fin     ~> the_enat
wenzelm@44968
  2004
wenzelm@44968
  2005
Every theorem name containing "inat", "Fin", "Infty", or "iSuc" has
wenzelm@44968
  2006
been renamed accordingly. INCOMPATIBILITY.
wenzelm@44968
  2007
wenzelm@44968
  2008
* Session Multivariate_Analysis: The euclidean_space type class now
wenzelm@44968
  2009
fixes a constant "Basis :: 'a set" consisting of the standard
wenzelm@44968
  2010
orthonormal basis for the type. Users now have the option of
wenzelm@44968
  2011
quantifying over this set instead of using the "basis" function, e.g.
wenzelm@44968
  2012
"ALL x:Basis. P x" vs "ALL i<DIM('a). P (basis i)".
wenzelm@44968
  2013
wenzelm@44968
  2014
* Session Multivariate_Analysis: Type "('a, 'b) cart" has been renamed
wenzelm@44968
  2015
to "('a, 'b) vec" (the syntax "'a ^ 'b" remains unaffected). Constants
wenzelm@44968
  2016
"Cart_nth" and "Cart_lambda" have been respectively renamed to
wenzelm@44968
  2017
"vec_nth" and "vec_lambda"; theorems mentioning those names have
wenzelm@44968
  2018
changed to match. Definition theorems for overloaded constants now use
wenzelm@44968
  2019
the standard "foo_vec_def" naming scheme. A few other theorems have
wenzelm@44968
  2020
been renamed as follows (INCOMPATIBILITY):
wenzelm@44968
  2021
wenzelm@44968
  2022
  Cart_eq          ~> vec_eq_iff
wenzelm@44968

  2025
  Cauchy_vector    ~> vec_CauchyI
wenzelm@44968
  2026
wenzelm@44968
  2027
* Session Multivariate_Analysis: Several duplicate theorems have been
wenzelm@44968
  2028
removed, and other theorems have been renamed or replaced with more
wenzelm@44968
  2029
general versions. INCOMPATIBILITY.

wenzelm@41944
  2147
wenzelm@43731
  2148
* The inner syntax of sort/type/term/prop supports inlined YXML
wenzelm@43731
  2149
representations within quoted string tokens.  By encoding logical
wenzelm@43731
  2150
entities via Term_XML (in ML or Scala) concrete syntax can be
wenzelm@43731
  2151
bypassed, which is particularly useful for producing bits of text

  2152
under external program control.
wenzelm@43731

  2170
* Inner syntax: identifiers in parse trees of generic categories
wenzelm@42056
  2171
"logic", "aprop", "idt" etc. carry position information (disguised as
wenzelm@42056
  2172
type constraints).  Occasional INCOMPATIBILITY with non-compliant
wenzelm@42057
  2173
translations that choke on unexpected type constraints.  Positions can
wenzelm@42057
  2174
be stripped in ML translations via Syntax.strip_positions /
wenzelm@42057
  2175
Syntax.strip_positions_ast, or via the syntax constant
wenzelm@42057
  2176
"_strip_positions" within parse trees.  As last resort, positions can
wenzelm@42057
  2177
be disabled via the configuration option Syntax.positions, which is
wenzelm@42057
  2178
called "syntax_positions" in Isar attribute syntax.
wenzelm@42056
  2179
wenzelm@42290
  2180
* Discontinued special status of various ML structures that contribute
wenzelm@42290
  2181
to structure Syntax (Ast, Lexicon, Mixfix, Parser, Printer etc.): less
wenzelm@42290
  2182
pervasive content, no inclusion in structure Syntax.  INCOMPATIBILITY,
wenzelm@42290

wenzelm@42370
  2189
* Refined PARALLEL_GOALS tactical: degrades gracefully for schematic
wenzelm@42370
  2190
goal states; body tactic needs to address all subgoals uniformly.
wenzelm@42370
  2191
wenzelm@42403
  2192
* Slightly more special eq_list/eq_set, with shortcut involving
wenzelm@42403
  2193
pointer equality (assumes that eq relation is reflexive).
wenzelm@42403
  2194
wenzelm@42793
  2195
* Classical tactics use proper Proof.context instead of historic types
wenzelm@42793
  2196
claset/clasimpset.  Old-style declarations like addIs, addEs, addDs
wenzelm@42793
  2197
operate directly on Proof.context.  Raw type claset retains its use as
wenzelm@42793
  2198
snapshot of the classical context, which can be recovered via
wenzelm@42793
  2199
(put_claset HOL_cs) etc.  Type clasimpset has been discontinued.
wenzelm@42793
  2200
INCOMPATIBILITY, classical tactics and derived proof methods require

uniformly by explicit Isabelle settings as follows:
wenzelm@44967
  2214

  2215
  ISABELLE_CSDP   (formerly CSDP_EXE)
wenzelm@44967

Note that automated detection from the file-system or search path has
wenzelm@44967
  2222
been discontinued.  INCOMPATIBILITY.
wenzelm@44967

* Scala layer provides JVM method invocation service for static
wenzelm@44800
  2225
methods of type (String)String, see Invoke_Scala.method in ML.  For
wenzelm@44800
  2226
example:
wenzelm@43752
  2227
wenzelm@43752
  2228
  Invoke_Scala.method "java.lang.System.getProperty" "java.home"
wenzelm@43752
  2229
wenzelm@44967
  2230
Together with YXML.string_of_body/parse_body and XML.Encode/Decode
wenzelm@44967
  2231
this allows to pass structured values between ML and Scala.

* The IsabelleText fonts includes some further glyphs to support the
wenzelm@44803
  2234

wenzelm@44803

  2243
*** General ***
wenzelm@37536
  2244
wenzelm@41573
  2245
* Experimental Prover IDE based on Isabelle/Scala and jEdit (see
wenzelm@41612
  2246
src/Tools/jEdit).  This also serves as IDE for Isabelle/ML, with
wenzelm@41612
  2247
useful tooltips and hyperlinks produced from its static analysis.  The
wenzelm@41612
  2248
bundled component provides an executable Isabelle tool that can be run
wenzelm@41612
  2249
like this:
wenzelm@41612
  2250
wenzelm@41612
  2251
  Isabelle2011/bin/isabelle jedit
wenzelm@41573
  2252
wenzelm@40948
  2253
* Significantly improved Isabelle/Isar implementation manual.
wenzelm@40948
  2254
wenzelm@41594
  2255
* System settings: ISABELLE_HOME_USER now includes ISABELLE_IDENTIFIER
wenzelm@41595
  2256
(and thus refers to something like $HOME/.isabelle/Isabelle2011),
wenzelm@41594
  2257
while the default heap location within that directory lacks that extra
wenzelm@41594
  2258
suffix.  This isolates multiple Isabelle installations from each
wenzelm@41594
  2259
other, avoiding problems with old settings in new versions.
wenzelm@41594
  2260
INCOMPATIBILITY, need to copy/upgrade old user settings manually.
wenzelm@41594
  2261
wenzelm@40947
  2262
* Source files are always encoded as UTF-8, instead of old-fashioned
wenzelm@40947
  2263
ISO-Latin-1.  INCOMPATIBILITY.  Isabelle LaTeX documents might require
wenzelm@40948
  2264
the following package declarations:
wenzelm@40947
  2265
wenzelm@40947
  2266
  \usepackage[utf8]{inputenc}
wenzelm@40947
  2267
  \usepackage{textcomp}
wenzelm@40947
  2268
krauss@41440
  2269
* Explicit treatment of UTF-8 sequences as Isabelle symbols, such that
wenzelm@37536
  2270
a Unicode character is treated as a single symbol, not a sequence of
wenzelm@37536
  2271
non-ASCII bytes as before.  Since Isabelle/ML string literals may
wenzelm@37536
  2272
contain symbols without further backslash escapes, Unicode can now be
wenzelm@37536
  2273
used here as well.  Recall that Symbol.explode in ML provides a
wenzelm@37536
  2274
consistent view on symbols, while raw explode (or String.explode)
wenzelm@37536
  2275
merely give a byte-oriented representation.
wenzelm@37536
  2276
wenzelm@41594
  2277
* Theory loader: source files are primarily located via the master
wenzelm@41594
  2278
directory of each theory node (where the .thy file itself resides).
wenzelm@41594
  2279
The global load path is still partially available as legacy feature.
wenzelm@41594
  2280
Minor INCOMPATIBILITY due to subtle change in file lookup: use
wenzelm@41594
  2281
explicit paths, relatively to the theory.
wenzelm@38135
  2282
wenzelm@37939
  2283
* Special treatment of ML file names has been discontinued.
wenzelm@37939
  2284
Historically, optional extensions .ML or .sml were added on demand --
wenzelm@37939
  2285
at the cost of clarity of file dependencies.  Recall that Isabelle/ML
wenzelm@37939
  2286
files exclusively use the .ML extension.  Minor INCOMPATIBILTY.
wenzelm@37939
  2287
wenzelm@38980
  2288
* Various options that affect pretty printing etc. are now properly
wenzelm@38767
  2289
handled within the context via configuration options, instead of
wenzelm@40879
  2290
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
  2357
entities in the context of the interpretation.  The 'interpretation'

that would be activated if the specified expression was interpreted in
wenzelm@41594

* Coercive subtyping: functions can be declared as coercions and type
wenzelm@41594
  2391
inference will add them as necessary upon input of a term.  Theory
wenzelm@41594
  2392
Complex_Main declares real :: nat => real and real :: int => real as
wenzelm@41594
  2393
coercions. A coercion function f is declared like this:
wenzelm@40939
  2394
wenzelm@40939
  2395
  declare [[coercion f]]
nipkow@40866
  2396
wenzelm@41571
  2397
To lift coercions through type constructors (e.g. from nat => real to
nipkow@40866
  2398
nat list => real list), map functions can be declared, e.g.
nipkow@40866
  2399
wenzelm@40939
  2400
  declare [[coercion_map map]]
wenzelm@40939
  2401
wenzelm@40939
  2402
Currently coercion inference is activated only in theories including
wenzelm@40939
  2403
real numbers, i.e. descendants of Complex_Main.  This is controlled by
wenzelm@41020
  2404
the configuration option "coercion_enabled", e.g. it can be enabled in
wenzelm@40939
  2405
other theories like this:
wenzelm@40939
  2406

* Datatype package: theorems generated for executable equality (class
wenzelm@41571
  2420
"eq") carry proper names and are treated as default code equations.
wenzelm@41571
  2421
wenzelm@41594
  2422
* Inductive package: now offers command 'inductive_simps' to
wenzelm@41594
  2423
automatically derive instantiated and simplified equations for
wenzelm@41594
  2424
inductive predicates, similar to 'inductive_cases'.
wenzelm@41594
  2425
wenzelm@41571
  2426
* Command 'enriched_type' allows to register properties of the
wenzelm@41571
  2427
functorial structure of types.
haftmann@39771
  2428
haftmann@39644
  2429
* Improved infrastructure for term evaluation using code generator

  2430
techniques, in particular static evaluation conversions.
haftmann@39644

wenzelm@41594
  2432
* Code generator: Scala (2.8 or higher) has been added to the target
wenzelm@41594
  2433
languages.
wenzelm@41594
  2434
haftmann@41398
  2435
* Code generator: globbing constant expressions "*" and "Theory.*"
haftmann@41398

  2441
haftmann@41398
  2442
* Code generator: do not print function definitions for case
haftmann@41398
  2443
combinators any longer.
haftmann@41398

* Code generator: simplification with rules determined with
wenzelm@41571

src/Tools/Code/code_simp.ML and method "code_simp".
wenzelm@41571
  2447
wenzelm@41594
  2448
* Code generator for records: more idiomatic representation of record
wenzelm@40948
  2449
types.  Warning: records are not covered by ancient SML code
wenzelm@40948
  2450
generation any longer.  INCOMPATIBILITY.  In cases of need, a suitable
wenzelm@40948
  2451
rep_datatype declaration helps to succeed then:
haftmann@38537
  2452
haftmann@38537
  2453
  record 'a foo = ...
haftmann@38537
  2454

  2455
  rep_datatype foo_ext ...
haftmann@38535
  2456
wenzelm@41594
  2457
* Records: logical foundation type for records does not carry a
wenzelm@41594
  2458
'_type' suffix any longer (obsolete due to authentic syntax).
wenzelm@41594
  2459
INCOMPATIBILITY.
wenzelm@41594
  2460
haftmann@41398
  2461
* Quickcheck now by default uses exhaustive testing instead of random
wenzelm@41571
  2462
testing.  Random testing can be invoked by "quickcheck [random]",
wenzelm@41571
  2463
exhaustive testing by "quickcheck [exhaustive]".
haftmann@41398
  2464
haftmann@41398
  2465
* Quickcheck instantiates polymorphic types with small finite
haftmann@41398
  2466
datatypes by default. This enables a simple execution mechanism to
haftmann@41398
  2467
handle quantifiers and function equality over the finite datatypes.
haftmann@41398
  2468
wenzelm@41571
  2469
* Quickcheck random generator has been renamed from "code" to
wenzelm@41571
  2470
"random".  INCOMPATIBILITY.
haftmann@41398
  2471
haftmann@41398
  2472
* Quickcheck now has a configurable time limit which is set to 30
haftmann@41398
  2473
seconds by default. This can be changed by adding [timeout = n] to the
haftmann@41398
  2474
quickcheck command. The time limit for Auto Quickcheck is still set
haftmann@41398
  2475
independently.
haftmann@38461
  2476
haftmann@38461

* Sledgehammer:
wenzelm@41571
  2481
  - Added "smt" and "remote_smt" provers based on the "smt" proof
wenzelm@41571
  2482
    method. See the Sledgehammer manual for details ("isabelle doc
wenzelm@41571
  2483
    sledgehammer").
blanchet@40059

  2492
    sledgehammer [timeout = 77 s] ~> sledgehammer [timeout = 77]
blanchet@40341

blanchet@40341
  2494
    INCOMPATIBILITY.
blanchet@40341
  2495
blanchet@40341
  2496
* Nitpick:
blanchet@40341
  2497
  - Renamed options:
blanchet@40341
  2498
    nitpick [timeout = 77 s] ~> nitpick [timeout = 77]
blanchet@40341
  2499
    nitpick [tac_timeout = 777 ms] ~> nitpick [tac_timeout = 0.777]
blanchet@40059
  2500
    INCOMPATIBILITY.
blanchet@40725
  2501
  - Added support for partial quotient types.
blanchet@40725
  2502
  - Added local versions of the "Nitpick.register_xxx" functions.
blanchet@40725
  2503
  - Added "whack" option.
blanchet@40725
  2504
  - Allow registration of quotient types as codatatypes.
blanchet@40725
  2505
  - Improved "merge_type_vars" option to merge more types.
blanchet@40725
  2506
  - Removed unsound "fast_descrs" option.
blanchet@40725
  2507
  - Added custom symmetry breaking for datatypes, making it possible to reach
blanchet@40725
  2508
    higher cardinalities.
blanchet@40725
  2509
  - Prevent the expansion of too large definitions.
blanchet@39957
  2510
wenzelm@41571
  2511
* Proof methods "metis" and "meson" now have configuration options
wenzelm@41571
  2512
"meson_trace", "metis_trace", and "metis_verbose" that can be enabled
wenzelm@41571
  2513
to diagnose these tools. E.g.
wenzelm@41571
  2514
wenzelm@41571
  2515
    using [[metis_trace = true]]
wenzelm@41571
  2516
haftmann@41398
  2517
* Auto Solve: Renamed "Auto Solve Direct".  The tool is now available
haftmann@41398
  2518
manually as command 'solve_direct'.
haftmann@41398
  2519
boehmes@41601
  2520
* The default SMT solver Z3 must be enabled explicitly (due to
boehmes@41601
  2521
licensing issues) by setting the environment variable
wenzelm@41603
  2522
Z3_NON_COMMERCIAL in etc/settings of the component, for example.  For
wenzelm@41603
  2523
commercial applications, the SMT solver CVC3 is provided as fall-back;
wenzelm@41603
  2524
changing the SMT solver is done via the configuration option
wenzelm@41603
  2525
"smt_solver".
boehmes@41432
  2526
boehmes@41432
  2527
* Remote SMT solvers need to be referred to by the "remote_" prefix,
wenzelm@41571
  2528
i.e. "remote_cvc3" and "remote_z3".
wenzelm@41571
  2529
wenzelm@41571
  2530
* Added basic SMT support for datatypes, records, and typedefs using
wenzelm@41571
  2531
the oracle mode (no proofs).  Direct support of pairs has been dropped
wenzelm@41571
  2532
in exchange (pass theorems fst_conv snd_conv pair_collapse to the SMT
wenzelm@41571
  2533
support for a similar behavior).  Minor INCOMPATIBILITY.
boehmes@41432
  2534
boehmes@40162
  2535
* Changed SMT configuration options:
boehmes@40162
  2536
  - Renamed:

  2537
    z3_proofs ~> smt_oracle (with inverted meaning)
boehmes@40162
  2538
    z3_trace_assms ~> smt_trace_used_facts
boehmes@40162
  2539
    INCOMPATIBILITY.

boehmes@40580
  2553
wenzelm@41594
  2554
* Simplification procedure "list_to_set_comprehension" rewrites list
wenzelm@41594
  2555
comprehensions applied to List.set to set comprehensions.  Occasional
wenzelm@41594
  2556
INCOMPATIBILITY, may be deactivated like this:
wenzelm@41594
  2557
wenzelm@41594

  declare [[simproc del: list_to_set_comprehension]]
wenzelm@41594
  2559
wenzelm@41573
  2560
* Removed old version of primrec package.  INCOMPATIBILITY.
haftmann@41398
  2561
haftmann@41398
  2562
* Removed simplifier congruence rule of "prod_case", as has for long
haftmann@41398
  2563
been the case with "split".  INCOMPATIBILITY.
haftmann@41398
  2564
haftmann@41398

* String.literal is a type, but not a datatype.  INCOMPATIBILITY.
haftmann@41398
  2566
krauss@40388
  2567
* Removed [split_format ... and ... and ...] version of

  2568
[split_format].  Potential INCOMPATIBILITY.
krauss@40388
  2569
wenzelm@41571
  2570
* Predicate "sorted" now defined inductively, with nice induction
wenzelm@41571
  2571
rules.  INCOMPATIBILITY: former sorted.simps now named sorted_simps.
haftmann@41398
  2572
haftmann@41398
  2573
* Constant "contents" renamed to "the_elem", to free the generic name
haftmann@41398
  2574
contents for other uses.  INCOMPATIBILITY.
haftmann@41398
  2575
haftmann@41398
  2576
* Renamed class eq and constant eq (for code generation) to class
haftmann@41398
  2577
equal and constant equal, plus renaming of related facts and various
haftmann@41398
  2578
tuning.  INCOMPATIBILITY.
haftmann@41398
  2579
haftmann@41398

wenzelm@41571
  2583
INCOMPATIBILITY.
haftmann@41398
  2584
haftmann@41398
  2585
* Renamed theory Fset to Cset, type Fset.fset to Cset.set, in order to
haftmann@41398
  2586
avoid confusion with finite sets.  INCOMPATIBILITY.
haftmann@41398
  2587
haftmann@41398
  2588
* Abandoned locales equiv, congruent and congruent2 for equivalence
haftmann@41398
  2589
relations.  INCOMPATIBILITY: use equivI rather than equiv_intro (same
haftmann@41398
  2590
for congruent(2)).
haftmann@41398

haftmann@41398
  2656
INCOMPATIBILITY.  Note that these were not supposed to be used
haftmann@41398
  2657
regularly unless for striking reasons; their main purpose was code
haftmann@41398
  2658
generation.
haftmann@41398

Various operations from the Haskell prelude are used for generating
haftmann@41398
  2661
Haskell code.

* Term "bij f" is now an abbreviation of "bij_betw f UNIV UNIV".  Term
wenzelm@41571
  2664
"surj f" is now an abbreviation of "range f = UNIV".  The theorems
wenzelm@41571
  2665
bij_def and surj_def are unchanged.  INCOMPATIBILITY.
haftmann@41398

"*" and "+" respectively.  INCOMPATIBILITY.
haftmann@41398
  2669
haftmann@41398

"Sum_Type.Plus" instead.
haftmann@41398
  2672
haftmann@41398
  2673
* Constant "split" has been merged with constant "prod_case"; names of
haftmann@41398
  2674
ML functions, facts etc. involving split have been retained so far,
haftmann@41398
  2675
though.  INCOMPATIBILITY.
haftmann@41398

  2678
instead.  INCOMPATIBILITY.
haftmann@41398
  2679

* Theory Library/Monad_Syntax provides do-syntax for monad types.
wenzelm@41594
