*** General ***
wenzelm@54702
     8
wenzelm@54702
     9
* Document antiquotation @{url} produces markup for the given URL,
wenzelm@54702
    10
which results in an active hyperlink within the text.
wenzelm@54702
    11
wenzelm@54705
    12
* Document antiquotation @{file_unchecked} is like @{file}, but does
wenzelm@54705
    13
not check existence within the file-system.
wenzelm@54705
    14
wenzelm@54732
    15
* Discontinued legacy_isub_isup, which was a temporary Isabelle/ML
wenzelm@54732
    16
workaround in Isabelle2013-1.  The prover process no longer accepts
wenzelm@54732
    17
old identifier syntax with \<^isub> or \<^isup>.

*** Prover IDE -- Isabelle/Scala/jEdit ***
wenzelm@54533
    21
wenzelm@54533
    22
* Auxiliary files ('ML_file' etc.) are managed by the Prover IDE.
wenzelm@54533
    23
Open text buffers take precedence over copies within the file-system.
wenzelm@54533
    24
wenzelm@54688
    25
* Document panel: simplied interaction where every single mouse click
wenzelm@54688
    26
(re)opens document via desktop environment or as jEdit buffer.

*** HOL ***
haftmann@54227
    30
haftmann@54745
    31
* Theorem disambiguation Inf_le_Sup (on finite sets) ~> Inf_fin_le_Sup_fin.
haftmann@54745
    32
INCOMPATBILITY.
haftmann@54745
    33
haftmann@54708
    34
* Code generations are provided for make, fields, extend and truncate
haftmann@54708
    35
operations on records.
haftmann@54708
    36
haftmann@54295
    37
* Qualified constant names Wellfounded.acc, Wellfounded.accp.
haftmann@54295
    38
INCOMPATIBILITY.
haftmann@54295
    39
haftmann@54228
    40
* Fact generalization and consolidation:
haftmann@54228
    41
    neq_one_mod_two, mod_2_not_eq_zero_eq_one_int ~> not_mod_2_eq_0_eq_1
haftmann@54228
    42
INCOMPATIBILITY.
haftmann@54228
    43
haftmann@54228
    44
* Purely algebraic definition of even.  Fact generalization and consolidation:
haftmann@54228
    45
    nat_even_iff_2_dvd, int_even_iff_2_dvd ~> even_iff_2_dvd
haftmann@54228
    46
    even_zero_(nat|int) ~> even_zero
haftmann@54228
    47
INCOMPATIBILITY.
wenzelm@54055
    48
haftmann@54489
    49
* Abolished neg_numeral.
haftmann@54489
    50
  * Canonical representation for minus one is "- 1".
haftmann@54489
    51
  * Canonical representation for other negative numbers is "- (numeral _)".
haftmann@54502
    52
  * When devising rule sets for number calculation, consider the
haftmann@54587
    53
    following canonical cases: 0, 1, numeral _, - 1, - numeral _.
haftmann@54587
    54
  * HOLogic.dest_number also recognizes numerals in non-canonical forms
haftmann@54587
    55
    like "numeral One", "- numeral One", "- 0" and even "- … - _".
haftmann@54489
    56
  * Syntax for negative numerals is mere input syntax.
haftmann@54489
    57
INCOMPATBILITY.
haftmann@54489
    58
haftmann@54230
    59
* Elimination of fact duplicates:
haftmann@54230
    60
    equals_zero_I ~> minus_unique
haftmann@54230
    61
    diff_eq_0_iff_eq ~> right_minus_eq
traytel@54588
    62
    nat_infinite ~> infinite_UNIV_nat
traytel@54588
    63
    int_infinite ~> infinite_UNIV_int
haftmann@54230
    64
INCOMPATIBILITY.
haftmann@54230
    65
haftmann@54230
    66
* Fact name consolidation:
haftmann@54230
    67
    diff_def, diff_minus, ab_diff_minus ~> diff_conv_add_uminus
haftmann@54250
    68
    minus_le_self_iff ~> neg_less_eq_nonneg
haftmann@54250
    69
    le_minus_self_iff ~> less_eq_neg_nonpos
haftmann@54250
    70
    neg_less_nonneg ~> neg_less_pos
haftmann@54250
    71
    less_minus_self_iff ~> less_neg_neg [simp]
haftmann@54230
    72
INCOMPATIBILITY.
haftmann@54230
    73
haftmann@54230
    74
* More simplification rules on unary and binary minus:
haftmann@54230
    75
add_diff_cancel, add_diff_cancel_left, add_le_same_cancel1,
haftmann@54230
    76
add_le_same_cancel2, add_less_same_cancel1, add_less_same_cancel2,
haftmann@54230
    77
add_minus_cancel, diff_add_cancel, le_add_same_cancel1,
haftmann@54230
    78
le_add_same_cancel2, less_add_same_cancel1, less_add_same_cancel2,
haftmann@54230
    79
minus_add_cancel, uminus_add_conv_diff.  These correspondingly
haftmann@54230
    80
have been taken away from fact collections algebra_simps and
haftmann@54230
    81
field_simps.  INCOMPATIBILITY.
haftmann@54230
    82
haftmann@54230
    83
To restore proofs, the following patterns are helpful:
haftmann@54230
    84
haftmann@54230
    85
a) Arbitrary failing proof not involving "diff_def":
haftmann@54230
    86
Consider simplification with algebra_simps or field_simps.
haftmann@54230
    87
haftmann@54230
    88
b) Lifting rules from addition to subtraction:
haftmann@54230
    89
Try with "using <rule for addition> of [… "- _" …]" by simp".
haftmann@54230
    90
haftmann@54230
    91
c) Simplification with "diff_def": just drop "diff_def".
haftmann@54230
    92
Consider simplification with algebra_simps or field_simps;
haftmann@54230
    93
or the brute way with
haftmann@54230
    94
"simp add: diff_conv_add_uminus del: add_uminus_conv_diff".
haftmann@54230
    95
hoelzl@54264
    96
* SUP and INF generalized to conditionally_complete_lattice
hoelzl@54264
    97
hoelzl@54264
    98
* Theory Lubs moved HOL image to HOL-Library. It is replaced by
hoelzl@54264
    99
Conditionally_Complete_Lattices.   INCOMPATIBILITY.
hoelzl@54264
   100
hoelzl@54264
   101
* Introduce bdd_above and bdd_below in Conditionally_Complete_Lattices, use them
hoelzl@54264
   102
instead of explicitly stating boundedness of sets.
hoelzl@54264
   103
Andreas@54631
   104
* ccpo.admissible quantifies only over non-empty chains to allow
Andreas@54631
   105
more syntax-directed proof rules; the case of the empty chain
Andreas@54631
   106
shows up as additional case in fixpoint induction proofs.
Andreas@54631
   107
INCOMPATIBILITY
hoelzl@54264
   108
wenzelm@54672
   109
* Nitpick:
wenzelm@54672
   110
  - Fixed soundness bug whereby mutually recursive datatypes could take
wenzelm@54672
   111
    infinite values.
wenzelm@54672
   112
immler@54787
   113
* HOL-Multivariate_Analysis:
immler@54787
   114
  - type class ordered_real_vector for ordered vector spaces
immler@54787
   115
  - changed order of ordered_euclidean_space to be compatible with
immler@54787
   116
    pointwise ordering on products. Therefore instance of
immler@54787
   117
    conditionally_complete_lattice and ordered_real_vector.
immler@54787
   118
    INCOMPATIBILITY: use box instead of greaterThanLessThan or
immler@54787
   119
    explicit set-comprehensions with eucl_less for other (half-) open
immler@54787
   120
    intervals.
immler@54787
   121
wenzelm@54672
   122
wenzelm@54449
   123
*** ML ***
wenzelm@54449
   124
wenzelm@54449
   125
* Toplevel function "use" refers to raw ML bootstrap environment,
wenzelm@54449
   126
without Isar context nor antiquotations.  Potential INCOMPATIBILITY.
wenzelm@54449
   127
Note that 'ML_file' is the canonical command to load ML files into the
wenzelm@54449
   128
formal context.
wenzelm@54449
   129
wenzelm@54742
   130
* Proper context for basic Simplifier operations: rewrite_rule,
wenzelm@54742
   131
rewrite_goals_rule, rewrite_goals_tac etc. INCOMPATIBILITY, need to
wenzelm@54742
   132
pass runtime Proof.context (and ensure that the simplified entity
wenzelm@54742
   133
actually belongs to it).
wenzelm@54742
   134
wenzelm@54449
   135
wenzelm@54683
   136
*** System ***
wenzelm@54683
   137
wenzelm@54683
   138
* Simplified "isabelle display" tool.  Settings variables DVI_VIEWER
wenzelm@54683
   139
and PDF_VIEWER now refer to the actual programs, not shell
wenzelm@54683
   140
command-lines.  Discontinued option -c: invocation may be asynchronous
wenzelm@54683
   141
via desktop environment, without any special precautions.  Potential
wenzelm@54683
   142
INCOMPATIBILITY with ambitious private settings.
wenzelm@54683
   143
wenzelm@54683
   144
* Improved 'display_drafts' concerning desktop integration and
wenzelm@54683
   145
repeated invocation in PIDE front-end: re-use single file
wenzelm@54683
   146
$ISABELLE_HOME_USER/tmp/drafts.pdf and corresponding views.
wenzelm@54683

-------------------------------------
wenzelm@54639
   152
wenzelm@54639
   153
*** Prover IDE -- Isabelle/Scala/jEdit ***
wenzelm@54639
   154
wenzelm@54639
   155
* More robust editing of running commands with internal forks,
wenzelm@54639
   156
e.g. non-terminating 'by' steps.
wenzelm@54639
   157
wenzelm@54641
   158
* More relaxed Sledgehammer panel: avoid repeated application of query
wenzelm@54641
   159
after edits surrounding the command location.
wenzelm@54641
   160
wenzelm@54648
   161
* More status information about commands that are interrupted
wenzelm@54648
   162
accidentally (via physical event or Poly/ML runtime system signal,
wenzelm@54648
   163
e.g. out-of-memory).
wenzelm@54648
   164
wenzelm@54653
   165
wenzelm@54653
   166
*** System ***
wenzelm@54653
   167
wenzelm@54653
   168
* More robust termination of external processes managed by
wenzelm@54664
   169
Isabelle/ML: support cancellation of tasks within the range of
wenzelm@54664
   170
milliseconds, as required for PIDE document editing with automatically
wenzelm@54664
   171
tried tools (e.g. Sledgehammer).
wenzelm@54653
   172
wenzelm@54648
   173
* Reactivated Isabelle/Scala kill command for external processes on
wenzelm@54648
   174
Mac OS X, which was accidentally broken in Isabelle2013-1 due to a
wenzelm@54648
   175
workaround for some Debian/Ubuntu Linux versions from 2013.
wenzelm@54648
   176
wenzelm@54639
   177
wenzelm@54639
   178
wenzelm@53971
   179
New in Isabelle2013-1 (November 2013)
wenzelm@53971
   180
-------------------------------------
wenzelm@50994
   181
wenzelm@51293
   182
*** General ***
wenzelm@51293
   183
wenzelm@53971
   184
* Discontinued obsolete 'uses' within theory header.  Note that
wenzelm@53971
   185
commands like 'ML_file' work without separate declaration of file
wenzelm@53971
   186
dependencies.  Minor INCOMPATIBILITY.
wenzelm@53971
   187
wenzelm@53971
   188
* Discontinued redundant 'use' command, which was superseded by
wenzelm@53971
   189
'ML_file' in Isabelle2013.  Minor INCOMPATIBILITY.
wenzelm@53971
   190
wenzelm@53016
   191
* Simplified subscripts within identifiers, using plain \<^sub>
wenzelm@53016
   192
instead of the second copy \<^isub> and \<^isup>.  Superscripts are
wenzelm@53016
   193
only for literal tokens within notation; explicit mixfix annotations
wenzelm@53016
   194
for consts or fixed variables may be used as fall-back for unusual
wenzelm@53016
   195
names.  Obsolete \<twosuperior> has been expanded to \<^sup>2 in
wenzelm@53016
   196
Isabelle/HOL.  INCOMPATIBILITY, use "isabelle update_sub_sup" to
wenzelm@53016
   197
standardize symbols as a starting point for further manual cleanup.
wenzelm@53016
   198
The ML reference variable "legacy_isub_isup" may be set as temporary
wenzelm@53016
   199
workaround, to make the prover accept a subset of the old identifier
wenzelm@53016
   200
syntax.
wenzelm@53016
   201
wenzelm@53021
   202
* Document antiquotations: term style "isub" has been renamed to
wenzelm@53021
   203
"sub".  Minor INCOMPATIBILITY.
wenzelm@53021
   204
wenzelm@52487
   205
* Uniform management of "quick_and_dirty" as system option (see also
wenzelm@52487
   206
"isabelle options"), configuration option within the context (see also
wenzelm@52487
   207
Config.get in Isabelle/ML), and attribute in Isabelle/Isar.  Minor
wenzelm@52487
   208
INCOMPATIBILITY, need to use more official Isabelle means to access
wenzelm@52487
   209
quick_and_dirty, instead of historical poking into mutable reference.
wenzelm@52059
   210
wenzelm@52060
   211
* Renamed command 'print_configs' to 'print_options'.  Minor
wenzelm@52060
   212
INCOMPATIBILITY.
wenzelm@52060
   213
wenzelm@52430
   214
* Proper diagnostic command 'print_state'.  Old 'pr' (with its
wenzelm@52430
   215
implicit change of some global references) is retained for now as
wenzelm@52430
   216
control command, e.g. for ProofGeneral 3.7.x.
wenzelm@52430
   217
wenzelm@52549
   218
* Discontinued 'print_drafts' command with its old-fashioned PS output
wenzelm@52549
   219
and Unix command-line print spooling.  Minor INCOMPATIBILITY: use
wenzelm@52549
   220
'display_drafts' instead and print via the regular document viewer.
wenzelm@52549
   221
wenzelm@53971
   222
* Updated and extended "isar-ref" and "implementation" manual,
wenzelm@53971
   223
eliminated old "ref" manual.
wenzelm@53971
   224
wenzelm@51293
   225
wenzelm@51533
   226
*** Prover IDE -- Isabelle/Scala/jEdit ***
wenzelm@51533
   227
wenzelm@53971
   228
* New manual "jedit" for Isabelle/jEdit, see isabelle doc or
wenzelm@53852
   229
Documentation panel.
wenzelm@53852
   230
wenzelm@53971
   231
* Dockable window "Documentation" provides access to Isabelle
wenzelm@53971
   232
documentation.
wenzelm@52646
   233
wenzelm@52949
   234
* Dockable window "Find" provides query operations for formal entities
wenzelm@52949
   235
(GUI front-end to 'find_theorems' command).
wenzelm@52949
   236
wenzelm@53050
   237
* Dockable window "Sledgehammer" manages asynchronous / parallel
wenzelm@53050
   238
sledgehammer runs over existing document sources, independently of
wenzelm@53050
   239
normal editing and checking process.
wenzelm@53050
   240
wenzelm@51533
   241
* Dockable window "Timing" provides an overview of relevant command
wenzelm@54332
   242
timing information, depending on option jedit_timing_threshold.  The
wenzelm@54332
   243
same timing information is shown in the extended tooltip of the
wenzelm@54332
   244
command keyword, when hovering the mouse over it while the CONTROL or
wenzelm@54332
   245
COMMAND modifier is pressed.
wenzelm@51533
   246
wenzelm@53971
   247
* Improved dockable window "Theories": Continuous checking of proof
wenzelm@53971
   248
document (visible and required parts) may be controlled explicitly,
wenzelm@53971
   249
using check box or shortcut "C+e ENTER".  Individual theory nodes may
wenzelm@53971
   250
be marked explicitly as required and checked in full, using check box
wenzelm@53971
   251
or shortcut "C+e SPACE".
wenzelm@53971
   252
wenzelm@54305
   253
* Improved completion mechanism, which is now managed by the
wenzelm@54305
   254
Isabelle/jEdit plugin instead of SideKick.  Refined table of Isabelle
wenzelm@54305
   255
symbol abbreviations (see $ISABELLE_HOME/etc/symbols).
wenzelm@54305
   256
wenzelm@54319
   257
* Standard jEdit keyboard shortcut C+b complete-word is remapped to
wenzelm@54319
   258
isabelle.complete for explicit completion in Isabelle sources.
wenzelm@54319
   259
INCOMPATIBILITY wrt. jEdit defaults, may have to invent new shortcuts
wenzelm@54319
   260
to resolve conflict.
wenzelm@54319
   261
wenzelm@54305
   262
* Improved support of various "minor modes" for Isabelle NEWS,
wenzelm@54305
   263
options, session ROOT etc., with completion and SideKick tree view.
wenzelm@54305
   264
wenzelm@53971
   265
* Strictly monotonic document update, without premature cancellation of
wenzelm@53971
   266
running transactions that are still needed: avoid reset/restart of
wenzelm@53971
   267
such command executions while editing.
wenzelm@53271
   268
wenzelm@53971
   269
* Support for asynchronous print functions, as overlay to existing
wenzelm@53971
   270
document content.
wenzelm@53971
   271
wenzelm@53971
   272
* Support for automatic tools in HOL, which try to prove or disprove
wenzelm@53971
   273
toplevel theorem statements.
wenzelm@53971
   274
wenzelm@53971
   275
* Action isabelle.reset-font-size resets main text area font size

* File specifications in jEdit (e.g. file browser) may refer to
wenzelm@54351
   281
$ISABELLE_HOME and $ISABELLE_HOME_USER on all platforms.  Discontinued
wenzelm@54351
   282
obsolete $ISABELLE_HOME_WINDOWS variable.
wenzelm@53971
   283
wenzelm@53971

   285
/ Global Options / Appearance".
wenzelm@53971
   286
wenzelm@53971
   287
* Improved support of native Mac OS X functionality via "MacOSX"

ballarin@54049
   293
* Commands 'interpretation' and 'sublocale' are now target-sensitive.
ballarin@54049
   294
In particular, 'interpretation' allows for non-persistent
ballarin@54049
   295
interpretation within "context ... begin ... end" blocks offering a
ballarin@54049
   296
light-weight alternative to 'sublocale'.  See "isar-ref" manual for
ballarin@54049
   297
details.
haftmann@51747
   298
ballarin@51565
   299
* Improved locales diagnostic command 'print_dependencies'.
ballarin@51565
   300
wenzelm@51313
   301
* Discontinued obsolete 'axioms' command, which has been marked as
wenzelm@51313
   302
legacy since Isabelle2009-2.  INCOMPATIBILITY, use 'axiomatization'
wenzelm@51313
   303
instead, while observing its uniform scope for polymorphism.
wenzelm@51313
   304
wenzelm@51316
   305
* Discontinued empty name bindings in 'axiomatization'.
wenzelm@51316
   306
INCOMPATIBILITY.
wenzelm@51316
   307
wenzelm@53971
   308
* System option "proofs" has been discontinued.  Instead the global
wenzelm@53971
   309
state of Proofterm.proofs is persistently compiled into logic images
wenzelm@53971
   310
as required, notably HOL-Proofs.  Users no longer need to change
wenzelm@53971
   311
Proofterm.proofs dynamically.  Minor INCOMPATIBILITY.
wenzelm@53971
   312
wenzelm@53971
   313
* Syntax translation functions (print_translation etc.) always depend
wenzelm@53971
   314
on Proof.context.  Discontinued former "(advanced)" option -- this is
wenzelm@53971
   315
now the default.  Minor INCOMPATIBILITY.
wenzelm@53971
   316
wenzelm@53971
   317
* Former global reference trace_unify_fail is now available as

   318
configuration option "unify_trace_failure" (global context only).
wenzelm@53971
   319
wenzelm@52463
   320
* SELECT_GOAL now retains the syntactic context of the overall goal
wenzelm@52463

wenzelm@52463
   322
situations.

hoelzl@51002
   326
wenzelm@54032
   327
* Stronger precedence of syntax for big intersection and union on
wenzelm@54032
   328
sets, in accordance with corresponding lattice operations.
wenzelm@54032
   329
INCOMPATIBILITY.
wenzelm@54032
   330
wenzelm@54032
   331
* Notation "{p:A. P}" now allows tuple patterns as well.
wenzelm@54032
   332
wenzelm@54032
   333
* Nested case expressions are now translated in a separate check phase
wenzelm@54032
   334
rather than during parsing. The data for case combinators is separated
wenzelm@54032
   335
from the datatype package. The declaration attribute
wenzelm@54032
   336
"case_translation" can be used to register new case combinators:
wenzelm@54032
   337
wenzelm@54032
   338
  declare [[case_translation case_combinator constructor1 ... constructorN]]
haftmann@52637

* Code generator:
wenzelm@53160
   341
  - 'code_printing' unifies 'code_const' / 'code_type' / 'code_class' /
wenzelm@53160
   342
    'code_instance'.
wenzelm@53160
   343
  - 'code_identifier' declares name hints for arbitrary identifiers in
wenzelm@53160
   344
    generated code, subsuming 'code_modulename'.
wenzelm@53983
   345
wenzelm@53983

See the isar-ref manual for syntax diagrams, and the HOL theories for
wenzelm@53983
   347
examples.
haftmann@52435
   348
wenzelm@54032
   349
* Attibute 'code': 'code' now declares concrete and abstract code
wenzelm@54032
   350
equations uniformly.  Use explicit 'code equation' and 'code abstract'
wenzelm@54032
   351
to distinguish both when desired.
wenzelm@54032
   352
wenzelm@54032
   353
* Discontinued theories Code_Integer and Efficient_Nat by a more
wenzelm@54032
   354
fine-grain stack of theories Code_Target_Int, Code_Binary_Nat,
wenzelm@54032
   355
Code_Target_Nat and Code_Target_Numeral.  See the tutorial on code

   356
generation for details.  INCOMPATIBILITY.
wenzelm@54032
   357
wenzelm@54032
   358
* Numeric types are mapped by default to target language numerals:
wenzelm@54032
   359
natural (replaces former code_numeral) and integer (replaces former
wenzelm@54032
   360
code_int).  Conversions are available as integer_of_natural /
wenzelm@54032
   361
natural_of_integer / integer_of_nat / nat_of_integer (in HOL) and
wenzelm@54032
   362
Code_Numeral.integer_of_natural / Code_Numeral.natural_of_integer (in
wenzelm@54032
   363
ML).  INCOMPATIBILITY.
wenzelm@54032
   364
wenzelm@54032
   365
* Function package: For mutually recursive functions f and g, separate
wenzelm@54032
   366
cases rules f.cases and g.cases are generated instead of unusable
wenzelm@54032
   367
f_g.cases which exposed internal sum types. Potential INCOMPATIBILITY,
wenzelm@54032
   368
in the case that the unusable rule was used nevertheless.
wenzelm@54032
   369
wenzelm@54032
   370
* Function package: For each function f, new rules f.elims are
wenzelm@54032
   371
generated, which eliminate equalities of the form "f x = t".
wenzelm@54032
   372
wenzelm@54032
   373
* New command 'fun_cases' derives ad-hoc elimination rules for
wenzelm@54032
   374
function equations as simplified instances of f.elims, analogous to
wenzelm@54032
   375
inductive_cases.  See ~~/src/HOL/ex/Fundefs.thy for some examples.
blanchet@53307
   376
kuncar@54021
   377
* Lifting:
kuncar@54021
   378
  - parametrized correspondence relations are now supported:
wenzelm@54378
   379
    + parametricity theorems for the raw term can be specified in
kuncar@54021
   380
      the command lift_definition, which allow us to generate stronger
kuncar@54021
   381
      transfer rules
kuncar@54021
   382
    + setup_lifting generates stronger transfer rules if parametric
kuncar@54021
   383
      correspondence relation can be generated
kuncar@54021
   384
    + various new properties of the relator must be specified to support
kuncar@54021
   385
      parametricity
kuncar@54021
   386
    + parametricity theorem for the Quotient relation can be specified
kuncar@54021
   387
  - setup_lifting generates domain rules for the Transfer package
kuncar@54021
   388
  - stronger reflexivity prover of respectfulness theorems for type
kuncar@54021
   389
    copies
kuncar@54021
   390
  - ===> and --> are now local. The symbols can be introduced
kuncar@54021
   391
    by interpreting the locale lifting_syntax (typically in an
kuncar@54021
   392
    anonymous context)
wenzelm@54378
   393
  - Lifting/Transfer relevant parts of Library/Quotient_* are now in
kuncar@54021
   394
    Main. Potential INCOMPATIBILITY
kuncar@54021
   395
  - new commands for restoring and deleting Lifting/Transfer context:
kuncar@54021
   396
    lifting_forget, lifting_update
wenzelm@54378
   397
  - the command print_quotmaps was renamed to print_quot_maps.
kuncar@54021
   398
    INCOMPATIBILITY
kuncar@54021
   399
kuncar@54021
   400
* Transfer:
wenzelm@54378
   401
  - better support for domains in Transfer: replace Domainp T
kuncar@54021
   402
    by the actual invariant in a transferred goal
kuncar@54021
   403
  - transfer rules can have as assumptions other transfer rules
kuncar@54021
   404
  - Experimental support for transferring from the raw level to the
kuncar@54021
   405
    abstract level: Transfer.transferred attribute
kuncar@54021
   406
  - Attribute version of the transfer method: untransferred attribute
kuncar@54021
   407
haftmann@52286
   408
* Reification and reflection:
wenzelm@53160
   409
  - Reification is now directly available in HOL-Main in structure
wenzelm@53160
   410
    "Reification".
wenzelm@53160
   411
  - Reflection now handles multiple lists with variables also.
wenzelm@53160
   412
  - The whole reflection stack has been decomposed into conversions.
haftmann@52286
   413
INCOMPATIBILITY.
haftmann@52286
   414
haftmann@51489
   415
* Revised devices for recursive definitions over finite sets:
haftmann@51489
   416
  - Only one fundamental fold combinator on finite set remains:
haftmann@51489
   417
    Finite_Set.fold :: ('a => 'b => 'b) => 'b => 'a set => 'b
haftmann@51489
   418
    This is now identity on infinite sets.
wenzelm@52745
   419
  - Locales ("mini packages") for fundamental definitions with
haftmann@51489
   420
    Finite_Set.fold: folding, folding_idem.
haftmann@51489
   421
  - Locales comm_monoid_set, semilattice_order_set and
haftmann@51489
   422
    semilattice_neutr_order_set for big operators on sets.
haftmann@51489
   423
    See theory Big_Operators for canonical examples.
haftmann@51489
   424
    Note that foundational constants comm_monoid_set.F and
haftmann@51489
   425
    semilattice_set.F correspond to former combinators fold_image
haftmann@51489
   426
    and fold1 respectively.  These are now gone.  You may use
haftmann@51490
   427
    those foundational constants as substitutes, but it is
wenzelm@53983
   428
    preferable to interpret the above locales accordingly.
haftmann@51489
   429
  - Dropped class ab_semigroup_idem_mult (special case of lattice,
haftmann@51489
   430
    no longer needed in connection with Finite_Set.fold etc.)
haftmann@51489
   431
  - Fact renames:
haftmann@51489
   432
      card.union_inter ~> card_Un_Int [symmetric]
haftmann@51489
   433
      card.union_disjoint ~> card_Un_disjoint
haftmann@51489
   434
INCOMPATIBILITY.
haftmann@51489
   435
haftmann@51487
   436
* Locale hierarchy for abstract orderings and (semi)lattices.
haftmann@51487
   437
wenzelm@53526
   438
* Complete_Partial_Order.admissible is defined outside the type class
wenzelm@53526
   439
ccpo, but with mandatory prefix ccpo. Admissibility theorems lose the
wenzelm@53526
   440
class predicate assumption or sort constraint when possible.
Andreas@53362
   441
INCOMPATIBILITY.
Andreas@53362
   442
wenzelm@53160
   443
* Introduce type class "conditionally_complete_lattice": Like a
wenzelm@53160
   444
complete lattice but does not assume the existence of the top and
wenzelm@53160
   445
bottom elements.  Allows to generalize some lemmas about reals and
wenzelm@53160
   446
extended reals.  Removed SupInf and replaced it by the instantiation
wenzelm@53160
   447
of conditionally_complete_lattice for real. Renamed lemmas about
wenzelm@53160
   448
conditionally-complete lattice from Sup_... to cSup_... and from
wenzelm@53160
   449
Inf_...  to cInf_... to avoid hidding of similar complete lattice
wenzelm@53160
   450
lemmas.
wenzelm@53160
   451
wenzelm@53160
   452
* Introduce type class linear_continuum as combination of
wenzelm@53160
   453
conditionally-complete lattices and inner dense linorders which have
wenzelm@53160
   454
more than one element.  INCOMPATIBILITY.
wenzelm@53160
   455
wenzelm@53983
   456
* Introduced type classes order_top and order_bot. The old classes top
wenzelm@53983
   457
and bot only contain the syntax without assumptions.  INCOMPATIBILITY:
wenzelm@53983
   458
Rename bot -> order_bot, top -> order_top
lammich@53683
   459
wenzelm@53160
   460
* Introduce type classes "no_top" and "no_bot" for orderings without
wenzelm@53160
   461
top and bottom elements.
hoelzl@51732
   462
hoelzl@51732
   463
* Split dense_linorder into inner_dense_order and no_top, no_bot.
hoelzl@51732
   464
hoelzl@51732
   465
* Complex_Main: Unify and move various concepts from
wenzelm@53160
   466
HOL-Multivariate_Analysis to HOL-Complex_Main.
hoelzl@51732
   467
wenzelm@53983
   468
 - Introduce type class (lin)order_topology and
wenzelm@53983
   469
   linear_continuum_topology.  Allows to generalize theorems about
wenzelm@53983
   470
   limits and order.  Instances are reals and extended reals.
hoelzl@51732
   471
hoelzl@51732
   472
 - continuous and continuos_on from Multivariate_Analysis:
wenzelm@53983
   473
   "continuous" is the continuity of a function at a filter.  "isCont"
wenzelm@53983
   474
   is now an abbrevitation: "isCont x f == continuous (at _) f".
wenzelm@53983
   475
wenzelm@53983
   476
   Generalized continuity lemmas from isCont to continuous on an
wenzelm@53983
   477
   arbitrary filter.
wenzelm@53983
   478
wenzelm@53983
   479
 - compact from Multivariate_Analysis. Use Bolzano's lemma to prove
wenzelm@53983
   480
   compactness of closed intervals on reals. Continuous functions
wenzelm@53983
   481
   attain infimum and supremum on compact sets. The inverse of a
wenzelm@53983
   482
   continuous function is continuous, when the function is continuous
wenzelm@53983
   483
   on a compact set.
hoelzl@51732
   484
hoelzl@51732
   485
 - connected from Multivariate_Analysis. Use it to prove the
hoelzl@51775
   486
   intermediate value theorem. Show connectedness of intervals on
hoelzl@51775
   487
   linear_continuum_topology).
hoelzl@51732
   488
hoelzl@51732
   489
 - first_countable_topology from Multivariate_Analysis. Is used to
wenzelm@53983
   490
   show equivalence of properties on the neighbourhood filter of x and
wenzelm@53983
   491
   on all sequences converging to x.
wenzelm@53983
   492
wenzelm@53983
   493
 - FDERIV: Definition of has_derivative moved to Deriv.thy. Moved
wenzelm@53983
   494
   theorems from Library/FDERIV.thy to Deriv.thy and base the
wenzelm@53983
   495
   definition of DERIV on FDERIV. Add variants of DERIV and FDERIV
wenzelm@53983
   496
   which are restricted to sets, i.e. to represent derivatives from
wenzelm@53983
   497
   left or right.
hoelzl@51732
   498
hoelzl@51732
   499
 - Removed the within-filter. It is replaced by the principal filter:
hoelzl@51732
   500
hoelzl@51732
   501
     F within X = inf F (principal X)
hoelzl@51732
   502
hoelzl@51732
   503
 - Introduce "at x within U" as a single constant, "at x" is now an
hoelzl@51732
   504
   abbreviation for "at x within UNIV"
hoelzl@51732
   505
wenzelm@53983
   506
 - Introduce named theorem collections tendsto_intros,
wenzelm@53983
   507
   continuous_intros, continuous_on_intros and FDERIV_intros. Theorems
wenzelm@53983
   508
   in tendsto_intros (or FDERIV_intros) are also available as
wenzelm@53983
   509
   tendsto_eq_intros (or FDERIV_eq_intros) where the right-hand side
wenzelm@53983
   510
   is replaced by a congruence rule. This allows to apply them as
wenzelm@53983
   511
   intro rules and then proving equivalence by the simplifier.
hoelzl@51732
   512
hoelzl@51732
   513
 - Restructured theories in HOL-Complex_Main:
hoelzl@51732
   514
hoelzl@51732
   515
   + Moved RealDef and RComplete into Real
hoelzl@51732
   516
hoelzl@51732
   517
   + Introduced Topological_Spaces and moved theorems about
hoelzl@51732
   518
     topological spaces, filters, limits and continuity to it
hoelzl@51732
   519
hoelzl@51732
   520
   + Renamed RealVector to Real_Vector_Spaces
hoelzl@51732
   521
wenzelm@53983
   522
   + Split Lim, SEQ, Series into Topological_Spaces,
wenzelm@53983
   523
     Real_Vector_Spaces, and Limits
hoelzl@51732
   524
hoelzl@51732
   525
   + Moved Ln and Log to Transcendental
hoelzl@51732
   526
hoelzl@51732
   527
   + Moved theorems about continuity from Deriv to Topological_Spaces
hoelzl@51732
   528
hoelzl@51732
   529
 - Remove various auxiliary lemmas.

hoelzl@51002
   532
blanchet@53738
   533
* Nitpick:
blanchet@53803
   534
  - Added option "spy"
blanchet@53738
   535
  - Reduce incidence of "too high arity" errors
blanchet@53738
   536
blanchet@51137
   537
* Sledgehammer:
blanchet@51137
   538
  - Renamed option:

   539
      isar_shrink ~> isar_compress
blanchet@53738
   540
    INCOMPATIBILITY.
blanchet@53801
   541
  - Added options "isar_try0", "spy"
blanchet@53728
   542
  - Better support for "isar_proofs"
blanchet@53766
   543
  - MaSh has been fined-tuned and now runs as a local server
blanchet@51137
   544
wenzelm@54032
   545
* Improved support for ad hoc overloading of constants (see also
wenzelm@54032

   582
~~/src/HOL/Algebra/poly.  Existing theories should be based on
wenzelm@53983

wenzelm@54032
   592
    coinduct).
wenzelm@54032

*** ML ***
wenzelm@51551
   608
wenzelm@53971
   609
* Spec_Check is a Quickcheck tool for Isabelle/ML.  The ML function
wenzelm@53971
   610
"check_property" allows to check specifications of the form "ALL x y
wenzelm@53971
   611
z. prop x y z".  See also ~~/src/Tools/Spec_Check/ with its

   612
Examples.thy in particular.
wenzelm@53971
   613
wenzelm@53709
   614
* Improved printing of exception trace in Poly/ML 5.5.1, with regular
wenzelm@53709
   615
tracing output in the command transaction context instead of physical
wenzelm@53709
   616

wenzelm@53709
   618
wenzelm@53971
   619
* ML type "theory" is now immutable, without any special treatment of
wenzelm@53971
   620
drafts or linear updates (which could lead to "stale theory" errors in
wenzelm@53971
   621
the past).  Discontinued obsolete operations like Theory.copy,
wenzelm@53971
   622
Theory.checkpoint, and the auxiliary type theory_ref.  Minor
wenzelm@53971
   623
INCOMPATIBILITY.
wenzelm@53164
   624
wenzelm@51551
   625
* More uniform naming of goal functions for skipped proofs:
wenzelm@51551
   626
wenzelm@51551
   627
    Skip_Proof.prove  ~>  Goal.prove_sorry
wenzelm@51551

    Skip_Proof.prove_global  ~>  Goal.prove_sorry_global
wenzelm@51551
   629
wenzelm@53971
   630
Minor INCOMPATIBILITY.
wenzelm@51703
   631
wenzelm@51717
   632
* Simplifier tactics and tools use proper Proof.context instead of
wenzelm@51717
   633
historic type simpset.  Old-style declarations like addsimps,
wenzelm@51717
   634
addsimprocs etc. operate directly on Proof.context.  Raw type simpset
wenzelm@51717
   635
retains its use as snapshot of the main Simplifier context, using
wenzelm@51717
   636
simpset_of and put_simpset on Proof.context.  INCOMPATIBILITY -- port
wenzelm@51717
   637
old tools by making them depend on (ctxt : Proof.context) instead of
wenzelm@51717
   638
(ss : simpset), then turn (simpset_of ctxt) into ctxt.
wenzelm@51717
   639
wenzelm@53971
   640
* Modifiers for classical wrappers (e.g. addWrapper, delWrapper)
wenzelm@53971
   641
operate on Proof.context instead of claset, for uniformity with addIs,
wenzelm@53971
   642
addEs, addDs etc. Note that claset_of and put_claset allow to manage
wenzelm@53971
   643
clasets separately from the context.
wenzelm@53971
   644
wenzelm@51717
   645
* Discontinued obsolete ML antiquotations @{claset} and @{simpset}.
wenzelm@51717
   646
INCOMPATIBILITY, use @{context} instead.
wenzelm@51717
   647
wenzelm@53971
   648
* Antiquotation @{theory_context A} is similar to @{theory A}, but
wenzelm@53971

wenzelm@52550
   662
wenzelm@52746

wenzelm@52746
   664
document formats: dvi.gz, ps, ps.gz -- the default document format is
wenzelm@52746
   665
always pdf.
wenzelm@52743
   666
wenzelm@52053
   667
* Isabelle settings variable ISABELLE_BUILD_JAVA_OPTIONS allows to
wenzelm@52053
   668
specify global resources of the JVM process run by isabelle build.
wenzelm@52053
   669
wenzelm@52116
   670
* Toplevel executable $ISABELLE_HOME/bin/isabelle_scala_script allows

   671
to run Isabelle/Scala source files as standalone programs.
wenzelm@52116
   672
wenzelm@52439
   673
* Improved "isabelle keywords" tool (for old-style ProofGeneral
wenzelm@52439
   674
keyword tables): use Isabelle/Scala operations, which inspect outer
wenzelm@52439
   675
syntax without requiring to build sessions first.
wenzelm@52439
   676
wenzelm@53971
   677
* Sessions may be organized via 'chapter' specifications in the ROOT
wenzelm@53971
   678
file, which determines a two-level hierarchy of browser info.  The old
wenzelm@53971
   679
tree-like organization via implicit sub-session relation (with its
wenzelm@53971
   680
tendency towards erratic fluctuation of URLs) has been discontinued.
wenzelm@53971
   681
The default chapter is called "Unsorted".  Potential INCOMPATIBILITY

*** General ***
wenzelm@47967
   690
wenzelm@50126
   691
* Theorem status about oracles and unfinished/failed future proofs is
wenzelm@50126
   692
no longer printed by default, since it is incompatible with
wenzelm@50126
   693
incremental / parallel checking of the persistent document model.  ML
wenzelm@50126
   694
function Thm.peek_status may be used to inspect a snapshot of the
wenzelm@50126
   695
ongoing evaluation process.  Note that in batch mode --- notably
wenzelm@50126
   696
isabelle build --- the system ensures that future proofs of all
wenzelm@50126
   697
accessible theorems in the theory context are finished (as before).
wenzelm@50126
   698
wenzelm@49699
   699
* Configuration option show_markup controls direct inlining of markup
wenzelm@49699
   700
into the printed representation of formal entities --- notably type
wenzelm@49699
   701
and sort constraints.  This enables Prover IDE users to retrieve that
wenzelm@49699
   702
information via tooltips in the output window, for example.
wenzelm@49699
   703
wenzelm@48890
   704
* Command 'ML_file' evaluates ML text from a file directly within the
wenzelm@48890
   705
theory, without any predeclaration via 'uses' in the theory header.
wenzelm@48890
   706
wenzelm@49243
   707
* Old command 'use' command and corresponding keyword 'uses' in the
wenzelm@49243
   708
theory header are legacy features and will be discontinued soon.
wenzelm@49243
   709
Tools that load their additional source files may imitate the
wenzelm@49243
   710
'ML_file' implementation, such that the system can take care of
wenzelm@49243
   711
dependencies properly.
wenzelm@49243
   712
wenzelm@47967
   713
* Discontinued obsolete method fastsimp / tactic fast_simp_tac, which
wenzelm@47967
   714
is called fastforce / fast_force_tac already since Isabelle2011-1.
wenzelm@47967
   715
wenzelm@50110
   716
* Updated and extended "isar-ref" and "implementation" manual, reduced
wenzelm@50110
   717
remaining material in old "ref" manual.
wenzelm@48120
   718
wenzelm@51050
   719
* Improved support for auxiliary contexts that indicate block structure
wenzelm@51050
   720
for specifications.  Nesting of "context fixes ... context assumes ..."
wenzelm@49841
   721
and "class ... context ...".
wenzelm@49841
   722
wenzelm@50772
   723
* Attribute "consumes" allows a negative value as well, which is
wenzelm@50778
   724
interpreted relatively to the total number of premises of the rule in
wenzelm@50772
   725
the target context.  This form of declaration is stable when exported
wenzelm@50772
   726
from a nested 'context' with additional assumptions.  It is the
wenzelm@50772
   727
preferred form for definitional packages, notably cases/rules produced
wenzelm@50772
   728
in HOL/inductive and HOL/function.
wenzelm@50772
   729
wenzelm@49869
   730
* More informative error messages for Isar proof commands involving
wenzelm@49869
   731
lazy enumerations (method applications etc.).
wenzelm@49869
   732
wenzelm@50213
   733
* Refined 'help' command to retrieve outer syntax commands according
wenzelm@50213
   734
to name patterns (with clickable results).

   737
*** Prover IDE -- Isabelle/Scala/jEdit ***
wenzelm@49968
   738
wenzelm@49968
   739
* Parallel terminal proofs ('by') are enabled by default, likewise
wenzelm@49968
   740
proofs that are built into packages like 'datatype', 'function'.  This
wenzelm@49968
   741
allows to "run ahead" checking the theory specifications on the
wenzelm@49968
   742
surface, while the prover is still crunching on internal
wenzelm@49968
   743
justifications.  Unfinished / cancelled proofs are restarted as
wenzelm@49968
   744
required to complete full proof checking eventually.
wenzelm@49968
   745
wenzelm@49968
   746
* Improved output panel with tooltips, hyperlinks etc. based on the
wenzelm@49968
   747
same Rich_Text_Area as regular Isabelle/jEdit buffers.  Activation of
wenzelm@49968
   748
tooltips leads to some window that supports the same recursively,
wenzelm@49968
   749
which can lead to stacks of tooltips as the semantic document content
wenzelm@49968
   750
is explored.  ESCAPE closes the whole stack, individual windows may be
wenzelm@49968
   751
closed separately, or detached to become independent jEdit dockables.
wenzelm@49968
   752
wenzelm@50717
   753
* Improved support for commands that produce graph output: the text
wenzelm@50717
   754
message contains a clickable area to open a new instance of the graph
wenzelm@50717
   755
browser on demand.
wenzelm@50717
   756
wenzelm@49968
   757
* More robust incremental parsing of outer syntax (partial comments,
wenzelm@49968
   758
malformed symbols).  Changing the balance of open/close quotes and
wenzelm@49968
   759
comment delimiters works more conveniently with unfinished situations
wenzelm@49968
   760
that frequently occur in user interaction.
wenzelm@49968
   761
wenzelm@49968
   762
* More efficient painting and improved reactivity when editing large
wenzelm@49968
   763
files.  More scalable management of formal document content.
wenzelm@49968
   764
wenzelm@50505
   765
* Smarter handling of tracing messages: prover process pauses after
wenzelm@50505
   766
certain number of messages per command transaction, with some user
wenzelm@50505
   767
dialog to stop or continue.  This avoids swamping the front-end with
wenzelm@50119
   768
potentially infinite message streams.
wenzelm@49968
   769
wenzelm@49968
   770
* More plugin options and preferences, based on Isabelle/Scala.  The
wenzelm@49968
   771
jEdit plugin option panel provides access to some Isabelle/Scala
wenzelm@49968
   772
options, including tuning parameters for editor reactivity and color
wenzelm@49968
   773
schemes.
wenzelm@49968
   774
wenzelm@50184
   775
* Dockable window "Symbols" provides some editing support for Isabelle
wenzelm@50184
   776
symbols.
wenzelm@50184
   777
wenzelm@51082
   778
* Dockable window "Monitor" shows ML runtime statistics.  Note that
wenzelm@51082
   779
continuous display of the chart slows down the system.
wenzelm@50701
   780
wenzelm@50183
   781
* Improved editing support for control styles: subscript, superscript,
wenzelm@50183
   782
bold, reset of style -- operating on single symbols or text
wenzelm@50198
   783
selections.  Cf. keyboard shortcuts C+e DOWN/UP/RIGHT/LEFT.
wenzelm@50198
   784
wenzelm@50198
   785
* Actions isabelle.increase-font-size and isabelle.decrease-font-size
wenzelm@50198
   786
adjust the main text area font size, and its derivatives for output,
wenzelm@50836
   787
tooltips etc.  Cf. keyboard shortcuts C-PLUS and C-MINUS, which often
wenzelm@50836
   788
need to be adapted to local keyboard layouts.
wenzelm@50183
   789
wenzelm@50730
   790
* More reactive completion popup by default: use \t (TAB) instead of
wenzelm@50730
   791
\n (NEWLINE) to minimize intrusion into regular flow of editing.  See
wenzelm@50730
   792
also "Plugin Options / SideKick / General / Code Completion Options".
wenzelm@50730
   793
wenzelm@50406
   794
* Implicit check and build dialog of the specified logic session
wenzelm@50406
   795
image.  For example, HOL, HOLCF, HOL-Nominal can be produced on
wenzelm@50406
   796
demand, without bundling big platform-dependent heap images in the
wenzelm@50406
   797
Isabelle distribution.
wenzelm@50406
   798
wenzelm@49968
   799
* Uniform Java 7 platform on Linux, Mac OS X, Windows: recent updates
wenzelm@49968
   800
from Oracle provide better multi-platform experience.  This version is
wenzelm@49968
   801
now bundled exclusively with Isabelle.

* Code generation for Haskell: restrict unqualified imports from
haftmann@48431
   807
Haskell Prelude to a small set of fundamental operations.
haftmann@48431
   808
wenzelm@50646
   809
* Command 'export_code': relative file names are interpreted
wenzelm@50646
   810
relatively to master directory of current theory rather than the
wenzelm@50646
   811
rather arbitrary current working directory.  INCOMPATIBILITY.
haftmann@48371
   812
wenzelm@48205
   813
* Discontinued obsolete attribute "COMP".  Potential INCOMPATIBILITY,
wenzelm@48205
   814
use regular rule composition via "OF" / "THEN", or explicit proof
wenzelm@48205
   815
structure instead.  Note that Isabelle/ML provides a variety of
wenzelm@48205
   816
operators like COMP, INCR_COMP, COMP_INCR, which need to be applied
wenzelm@48205
   817
with some care where this is really required.
wenzelm@48205
   818
wenzelm@48792
   819
* Command 'typ' supports an additional variant with explicit sort
wenzelm@48792
   820
constraint, to infer and check the most general type conforming to a
wenzelm@51063
   821

wenzelm@49836
   868
* Simplified 'typedef' specifications: historical options for implicit
wenzelm@49836
   869
set definition and alternative name have been discontinued.  The
wenzelm@49836
   870
former behavior of "typedef (open) t = A" is now the default, but
wenzelm@49836
   871
written just "typedef t = A".  INCOMPATIBILITY, need to adapt theories

   901
* Generalized the definition of limits:
wenzelm@50646
   902
wenzelm@50646
   903
  - Introduced the predicate filterlim (LIM x F. f x :> G) which
wenzelm@50646
   904
    expresses that when the input values x converge to F then the
wenzelm@50646
   905
    output f x converges to G.
wenzelm@50646
   906
wenzelm@50646
   907
  - Added filters for convergence to positive (at_top) and negative
wenzelm@50646
   908
    infinity (at_bot).
wenzelm@50646
   909
wenzelm@50646
   910
  - Moved infinity in the norm (at_infinity) from
wenzelm@50646

wenzelm@50646
   913
  - Removed real_tendsto_inf, it is superseded by "LIM x F. f x :>
wenzelm@50646

   934
      strict_prefix ~> prefix
Christian@49145
   935
wenzelm@50646
   936
  - Replaced constant "postfix" by "suffixeq" with swapped argument
wenzelm@50646
   937
    order (i.e., "postfix xs ys" is now "suffixeq ys xs") and dropped
wenzelm@50646
   938
    old infix syntax "xs >>= ys"; use "suffixeq ys xs" instead.
wenzelm@50646
   939
    Renamed lemmas accordingly.
wenzelm@50646
   940
wenzelm@50646
   941
  - Added constant "list_hembeq" for homeomorphic embedding on

wenzelm@50646
   946
    class instances for the prefix order (merely corresponding locale
wenzelm@50646
   947
    interpretations). The type class instances are now in theory
wenzelm@50646
   948
    Library/Prefix_Order.
wenzelm@50646
   949
wenzelm@50646

wenzelm@50646
  1004
* Theory Library/RBT_Impl: efficient construction of red-black trees
wenzelm@50646

wenzelm@50646
  1097
* The default limit for maximum number of worker threads is now 8,
wenzelm@50646
  1098
instead of 4, in correspondence to capabilities of contemporary
wenzelm@50646
  1099
hardware and Poly/ML runtime system.
wenzelm@50646
  1100
wenzelm@49869
  1101
* Type Seq.results and related operations support embedded error
wenzelm@49869
  1102
messages within lazy enumerations, and thus allow to provide
wenzelm@49869
  1103
informative errors in the absence of any usable results.
wenzelm@49869
  1104
wenzelm@48992
  1105
* Renamed Position.str_of to Position.here to emphasize that this is a
wenzelm@48992
  1106
formal device to inline positions into message text, but not
wenzelm@48992
  1107
necessarily printing visible text.

  1112
* Advanced support for Isabelle sessions and build management, see
wenzelm@48585
  1113
"system" manual for the chapter of that name, especially the "isabelle
wenzelm@51056
  1114
build" tool and its examples.  The "isabelle mkroot" tool prepares
wenzelm@51056
  1115
session root directories for use with "isabelle build", similar to
wenzelm@51056
  1116
former "isabelle mkdir" for "isabelle usedir".  Note that this affects
wenzelm@51056
  1117
document preparation as well.  INCOMPATIBILITY, isabelle usedir /
wenzelm@48736
  1118
mkdir / make are rendered obsolete.
wenzelm@48736
  1119
wenzelm@51056
  1120
* Discontinued obsolete Isabelle/build script, it is superseded by the
wenzelm@51056
  1121
regular isabelle build tool.  For example:
wenzelm@51056
  1122
wenzelm@51056
  1123
  isabelle build -s -b HOL
wenzelm@51056
  1124
wenzelm@48736
  1125
* Discontinued obsolete "isabelle makeall".
wenzelm@48585
  1126
wenzelm@48722
  1127
* Discontinued obsolete IsaMakefile and ROOT.ML files from the
wenzelm@48722
  1128
Isabelle distribution, except for rudimentary src/HOL/IsaMakefile that
wenzelm@48722
  1129
provides some traditional targets that invoke "isabelle build".  Note
wenzelm@48722
  1130
that this is inefficient!  Applications of Isabelle/HOL involving
wenzelm@48722
  1131
"isabelle make" should be upgraded to use "isabelle build" directly.
wenzelm@48722
  1132
wenzelm@48693
  1133
* The "isabelle options" tool prints Isabelle system options, as
wenzelm@48693
  1134
required for "isabelle build", for example.
wenzelm@48693
  1135
wenzelm@50646
  1136
* The "isabelle logo" tool produces EPS and PDF format simultaneously.
wenzelm@50646
  1137
Minor INCOMPATIBILITY in command-line options.
wenzelm@50646
  1138
wenzelm@50646
  1139
* The "isabelle install" tool has now a simpler command-line.  Minor
wenzelm@50646
  1140
INCOMPATIBILITY.
wenzelm@50646
  1141
wenzelm@48844
  1142
* The "isabelle components" tool helps to resolve add-on components
wenzelm@48844
  1143
that are not bundled, or referenced from a bare-bones repository
wenzelm@48844
  1144

platform family: "linux", "macos", "windows".
wenzelm@50646
  1148
wenzelm@50646
  1149
* The ML system is configured as regular component, and no longer
wenzelm@50646
  1150
picked up from some surrounding directory.  Potential INCOMPATIBILITY
wenzelm@50646
  1151
for home-made settings.
wenzelm@50132
  1152
wenzelm@50701
  1153
* Improved ML runtime statistics (heap, threads, future tasks etc.).
wenzelm@50701
  1154
wenzelm@48206
  1155
* Discontinued support for Poly/ML 5.2.1, which was the last version
wenzelm@48206
  1156
without exception positions and advanced ML compiler/toplevel
wenzelm@48206
  1157
configuration.
wenzelm@48206
  1158
wenzelm@48574
  1159
* Discontinued special treatment of Proof General -- no longer guess
wenzelm@48574
  1160
PROOFGENERAL_HOME based on accidental file-system layout.  Minor
wenzelm@48574
  1161
INCOMPATIBILITY: provide PROOFGENERAL_HOME and PROOFGENERAL_OPTIONS
wenzelm@48574
  1162
settings manually, or use a Proof General version that has been
wenzelm@48574
  1163
bundled as Isabelle component.

wenzelm@45593
  1170
*** General ***
wenzelm@45593
  1171
wenzelm@45614
  1172
* Prover IDE (PIDE) improvements:
wenzelm@45614
  1173
wenzelm@47585
  1174
  - more robust Sledgehammer integration (as before the sledgehammer
wenzelm@47806
  1175
    command-line needs to be typed into the source buffer)
wenzelm@45614
  1176
  - markup for bound variables
wenzelm@47806
  1177
  - markup for types of term variables (displayed as tooltips)
wenzelm@46956
  1178
  - support for user-defined Isar commands within the running session
wenzelm@47158
  1179
  - improved support for Unicode outside original 16bit range
wenzelm@47158
  1180
    e.g. glyph for \<A> (thanks to jEdit 4.5.1)
wenzelm@45614
  1181
wenzelm@47806
  1182
* Forward declaration of outer syntax keywords within the theory
wenzelm@47806
  1183
header -- minor INCOMPATIBILITY for user-defined commands.  Allow new
wenzelm@47806
  1184
commands to be used in the same theory where defined.
wenzelm@46485
  1185
wenzelm@47482
  1186
* Auxiliary contexts indicate block structure for specifications with
wenzelm@47482
  1187
additional parameters and assumptions.  Such unnamed contexts may be
wenzelm@47482
  1188
nested within other targets, like 'theory', 'locale', 'class',
wenzelm@47482
  1189
'instantiation' etc.  Results from the local context are generalized
wenzelm@47482
  1190
accordingly and applied to the enclosing target context.  Example:
wenzelm@47482
  1191
wenzelm@47482
  1192
  context
wenzelm@47482
  1193
    fixes x y z :: 'a
wenzelm@47482
  1194
    assumes xy: "x = y" and yz: "y = z"
wenzelm@47482
  1195
  begin
wenzelm@47482
  1196
wenzelm@47482
  1197
  lemma my_trans: "x = z" using xy yz by simp
wenzelm@47482
  1198
wenzelm@47482
  1199
  end
wenzelm@47482
  1200
wenzelm@47482
  1201
  thm my_trans
wenzelm@47482
  1202
wenzelm@47482
  1203
The most basic application is to factor-out context elements of
wenzelm@47482
  1204
several fixes/assumes/shows theorem statements, e.g. see
wenzelm@47482
  1205
~~/src/HOL/Isar_Examples/Group_Context.thy
wenzelm@47482
  1206
wenzelm@47482
  1207
Any other local theory specification element works within the "context
wenzelm@47482
  1208
... begin ... end" block as well.
wenzelm@47482
  1209
wenzelm@47484
  1210
* Bundled declarations associate attributed fact expressions with a
wenzelm@47484
  1211
given name in the context.  These may be later included in other
wenzelm@47484
  1212
contexts.  This allows to manage context extensions casually, without
wenzelm@47855
  1213
the logical dependencies of locales and locale interpretation.  See
wenzelm@47855
  1214
commands 'bundle', 'include', 'including' etc. in the isar-ref manual.
wenzelm@47484
  1215
wenzelm@47829
  1216
* Commands 'lemmas' and 'theorems' allow local variables using 'for'
wenzelm@47829
  1217
declaration, and results are standardized before being stored.  Thus
wenzelm@47829
  1218
old-style "standard" after instantiation or composition of facts
wenzelm@47829
  1219
becomes obsolete.  Minor INCOMPATIBILITY, due to potential change of
wenzelm@47829
  1220
indices of schematic variables.
wenzelm@47829
  1221
wenzelm@47829
  1222
* Rule attributes in local theory declarations (e.g. locale or class)
wenzelm@47829
  1223
are now statically evaluated: the resulting theorem is stored instead
wenzelm@47829
  1224
of the original expression.  INCOMPATIBILITY in rare situations, where
wenzelm@47829
  1225
the historic accident of dynamic re-evaluation in interpretations
wenzelm@47829
  1226
etc. was exploited.
wenzelm@47829
  1227
wenzelm@47829
  1228
* New tutorial "Programming and Proving in Isabelle/HOL"
wenzelm@47829
  1229
("prog-prove").  It completely supersedes "A Tutorial Introduction to
wenzelm@47829
  1230
Structured Isar Proofs" ("isar-overview"), which has been removed.  It
wenzelm@47829
  1231
also supersedes "Isabelle/HOL, A Proof Assistant for Higher-Order
wenzelm@47829
  1232
Logic" as the recommended beginners tutorial, but does not cover all
wenzelm@47829
  1233
of the material of that old tutorial.
wenzelm@47829
  1234
wenzelm@47829
  1235
* Updated and extended reference manuals: "isar-ref",
wenzelm@47829
  1236
"implementation", "system"; reduced remaining material in old "ref"
wenzelm@47829
  1237
manual.

  1240
*** Pure ***
wenzelm@47829
  1241
wenzelm@46976
  1242
* Command 'definition' no longer exports the foundational "raw_def"
wenzelm@46976
  1243
into the user context.  Minor INCOMPATIBILITY, may use the regular
wenzelm@46976
  1244
"def" result with attribute "abs_def" to imitate the old version.
wenzelm@46976
  1245
wenzelm@47855
  1246
* Attribute "abs_def" turns an equation of the form "f x y == t" into
wenzelm@47855
  1247
"f == %x y. t", which ensures that "simp" or "unfold" steps always
wenzelm@47855
  1248
expand it.  This also works for object-logic equality.  (Formerly
wenzelm@47855
  1249
undocumented feature.)
wenzelm@47855
  1250
wenzelm@47856
  1251
* Sort constraints are now propagated in simultaneous statements, just
wenzelm@47856
  1252
like type constraints.  INCOMPATIBILITY in rare situations, where
wenzelm@47856
  1253
distinct sorts used to be assigned accidentally.  For example:
wenzelm@47856
  1254
wenzelm@47856
  1255
  lemma "P (x::'a::foo)" and "Q (y::'a::bar)"  -- "now illegal"
wenzelm@47856
  1256
wenzelm@47856
  1257
  lemma "P (x::'a)" and "Q (y::'a::bar)"
wenzelm@47856
  1258
    -- "now uniform 'a::bar instead of default sort for first occurrence (!)"
wenzelm@47856
  1259
wenzelm@47856
  1260
* Rule composition via attribute "OF" (or ML functions OF/MRS) is more
wenzelm@47856
  1261
tolerant against multiple unifiers, as long as the final result is
wenzelm@47856
  1262
unique.  (As before, rules are composed in canonical right-to-left
wenzelm@47856
  1263
order to accommodate newly introduced premises.)
wenzelm@47856
  1264
wenzelm@47806
  1265
* Renamed some inner syntax categories:
wenzelm@47806
  1266
wenzelm@47806
  1267
    num ~> num_token
wenzelm@47806
  1268
    xnum ~> xnum_token
wenzelm@47806
  1269
    xstr ~> str_token
wenzelm@47806
  1270
wenzelm@47806
  1271
Minor INCOMPATIBILITY.  Note that in practice "num_const" or
wenzelm@47806
  1272
"num_position" etc. are mainly used instead (which also include
wenzelm@47806
  1273
position information via constraints).
wenzelm@47806
  1274
wenzelm@47829
  1275
* Simplified configuration options for syntax ambiguity: see
wenzelm@47829
  1276
"syntax_ambiguity_warning" and "syntax_ambiguity_limit" in isar-ref
wenzelm@47829
  1277
manual.  Minor INCOMPATIBILITY.
wenzelm@47829
  1278
wenzelm@47856
  1279
* Discontinued configuration option "syntax_positions": atomic terms
wenzelm@47856
  1280
in parse trees are always annotated by position constraints.
wenzelm@45134
  1281
wenzelm@47464
  1282
* Old code generator for SML and its commands 'code_module',
wenzelm@45383
  1283
'code_library', 'consts_code', 'types_code' have been discontinued.
haftmann@46028
  1284
Use commands of the generic code generator instead.  INCOMPATIBILITY.
wenzelm@45383
  1285
wenzelm@47464
  1286
* Redundant attribute "code_inline" has been discontinued. Use
wenzelm@47464
  1287
"code_unfold" instead.  INCOMPATIBILITY.
wenzelm@47464
  1288
wenzelm@47464
  1289
* Dropped attribute "code_unfold_post" in favor of the its dual
wenzelm@47464
  1290
"code_abbrev", which yields a common pattern in definitions like
haftmann@46028
  1291
haftmann@46028
  1292
  definition [code_abbrev]: "f = t"
haftmann@46028
  1293
haftmann@46028
  1294
INCOMPATIBILITY.
wenzelm@45383
  1295
wenzelm@47856
  1296
* Obsolete 'types' command has been discontinued.  Use 'type_synonym'
wenzelm@47856
  1297
instead.  INCOMPATIBILITY.
wenzelm@47856
  1298
wenzelm@47856
  1299
* Discontinued old "prems" fact, which used to refer to the accidental
wenzelm@47856
  1300
collection of foundational premises in the context (already marked as
wenzelm@47856
  1301
legacy since Isabelle2011).

* Type 'a set is now a proper type constructor (just as before
wenzelm@47464
  1307
Isabelle2008).  Definitions mem_def and Collect_def have disappeared.
wenzelm@47464
  1308
Non-trivial INCOMPATIBILITY.  For developments keeping predicates and
wenzelm@47855
  1309
sets separate, it is often sufficient to rephrase some set S that has
wenzelm@47855
  1310
been accidentally used as predicates by "%x. x : S", and some
wenzelm@47855
  1311
predicate P that has been accidentally used as set by "{x. P x}".
wenzelm@47855
  1312
Corresponding proofs in a first step should be pruned from any
wenzelm@47855
  1313
tinkering with former theorems mem_def and Collect_def as far as
wenzelm@47855
  1314
possible.
wenzelm@47855
  1315
wenzelm@47855
  1316
For developments which deliberately mix predicates and sets, a
wenzelm@47464
  1317
planning step is necessary to determine what should become a predicate
wenzelm@47464
  1318
and what a set.  It can be helpful to carry out that step in
wenzelm@47464
  1319
Isabelle2011-1 before jumping right into the current release.
wenzelm@47464
  1320
wenzelm@47855
  1321
* Code generation by default implements sets as container type rather
wenzelm@47855
  1322
than predicates.  INCOMPATIBILITY.
wenzelm@47855
  1323
wenzelm@47855

* New type synonym 'a rel = ('a * 'a) set
wenzelm@47855

wenzelm@47464
  1326
* The representation of numerals has changed.  Datatype "num"
wenzelm@47464
  1327
represents strictly positive binary numerals, along with functions
wenzelm@47464
  1328
"numeral :: num => 'a" and "neg_numeral :: num => 'a" to represent
wenzelm@47855
  1329
positive and negated numeric literals, respectively.  See also
wenzelm@47855
  1330
definitions in ~~/src/HOL/Num.thy.  Potential INCOMPATIBILITY, some
wenzelm@47855
  1331
user theories may require adaptations as follows:
huffman@47108
  1332
huffman@47108
  1333
  - Theorems with number_ring or number_semiring constraints: These
huffman@47108
  1334
    classes are gone; use comm_ring_1 or comm_semiring_1 instead.
huffman@47108
  1335
huffman@47108
  1336
  - Theories defining numeric types: Remove number, number_semiring,
huffman@47108
  1337
    and number_ring instances. Defer all theorems about numerals until
huffman@47108
  1338
    after classes one and semigroup_add have been instantiated.
huffman@47108
  1339
huffman@47108
  1340
  - Numeral-only simp rules: Replace each rule having a "number_of v"
huffman@47108
  1341
    pattern with two copies, one for numeral and one for neg_numeral.
huffman@47108
  1342
huffman@47108
  1343
  - Theorems about subclasses of semiring_1 or ring_1: These classes
huffman@47108
  1344
    automatically support numerals now, so more simp rules and
huffman@47108
  1345
    simprocs may now apply within the proof.
huffman@47108
  1346
huffman@47108
  1347
  - Definitions and theorems using old constructors Pls/Min/Bit0/Bit1:
huffman@47108
  1348
    Redefine using other integer operations.
huffman@47108
  1349
wenzelm@47855
  1350
* Transfer: New package intended to generalize the existing
wenzelm@47855
  1351
"descending" method and related theorem attributes from the Quotient
wenzelm@47855
  1352
package.  (Not all functionality is implemented yet, but future
wenzelm@47855
  1353
development will focus on Transfer as an eventual replacement for the
wenzelm@47855
  1354
corresponding parts of the Quotient package.)
wenzelm@47809
  1355
wenzelm@47809
  1356
  - transfer_rule attribute: Maintains a collection of transfer rules,
wenzelm@47809
  1357
    which relate constants at two different types. Transfer rules may
wenzelm@47809
  1358
    relate different type instances of the same polymorphic constant,
wenzelm@47809
  1359
    or they may relate an operation on a raw type to a corresponding
wenzelm@47809
  1360
    operation on an abstract type (quotient or subtype). For example:
wenzelm@47809
  1361
wenzelm@47809
  1362
    ((A ===> B) ===> list_all2 A ===> list_all2 B) map map
wenzelm@47809
  1363
    (cr_int ===> cr_int ===> cr_int) (%(x,y) (u,v). (x+u, y+v)) plus_int
wenzelm@47809
  1364
wenzelm@47809
  1365
  - transfer method: Replaces a subgoal on abstract types with an
wenzelm@47809
  1366
    equivalent subgoal on the corresponding raw types. Constants are
wenzelm@47809
  1367
    replaced with corresponding ones according to the transfer rules.
wenzelm@47809
  1368
    Goals are generalized over all free variables by default; this is
huffman@47851
  1369
    necessary for variables whose types change, but can be overridden
wenzelm@47855
  1370
    for specific variables with e.g. "transfer fixing: x y z".  The
wenzelm@47809
  1371
    variant transfer' method allows replacing a subgoal with one that
wenzelm@47809
  1372
    is logically stronger (rather than equivalent).
wenzelm@47809
  1373
wenzelm@47809
  1374
  - relator_eq attribute: Collects identity laws for relators of
wenzelm@47809
  1375
    various type constructors, e.g. "list_all2 (op =) = (op =)".  The
wenzelm@47809
  1376
    transfer method uses these lemmas to infer transfer rules for
wenzelm@47809
  1377
    non-polymorphic constants on the fly.
wenzelm@47809
  1378
wenzelm@47809
  1379
  - transfer_prover method: Assists with proving a transfer rule for a
wenzelm@47809
  1380
    new constant, provided the constant is defined in terms of other
wenzelm@47809
  1381
    constants that already have transfer rules. It should be applied
wenzelm@47809
  1382
    after unfolding the constant definitions.

* Lifting: New package intended to generalize the quotient_definition
huffman@47851
  1388
facility of the Quotient package; designed to work with Transfer.
wenzelm@47809
  1389
wenzelm@47809
  1390
  - lift_definition command: Defines operations on an abstract type in
wenzelm@47809
  1391
    terms of a corresponding operation on a representation
wenzelm@47809
  1392
    type.  Example syntax:
wenzelm@47809
  1393
wenzelm@47809
  1394
    lift_definition dlist_insert :: "'a => 'a dlist => 'a dlist"
wenzelm@47809
  1395
      is List.insert
wenzelm@47809
  1396
wenzelm@47809
  1397
    Users must discharge a respectfulness proof obligation when each
wenzelm@47809
  1398
    constant is defined. (For a type copy, i.e. a typedef with UNIV,
wenzelm@47809
  1399
    the proof is discharged automatically.) The obligation is
wenzelm@47809
  1400
    presented in a user-friendly, readable form; a respectfulness
wenzelm@47809
  1401
    theorem in the standard format and a transfer rule are generated
wenzelm@47809
  1402
    by the package.
wenzelm@47809
  1403
wenzelm@47809
  1404
  - Integration with code_abstype: For typedefs (e.g. subtypes
wenzelm@47809
  1405
    corresponding to a datatype invariant, such as dlist),
wenzelm@47809
  1406
    lift_definition generates a code certificate theorem and sets up
wenzelm@47809
  1407
    code generation for each constant.
wenzelm@47809
  1408
wenzelm@47809
  1409
  - setup_lifting command: Sets up the Lifting package to work with a
wenzelm@47809
  1410
    user-defined type. The user must provide either a quotient theorem
wenzelm@47809
  1411
    or a type_definition theorem.  The package configures transfer
wenzelm@47809
  1412
    rules for equality and quantifiers on the type, and sets up the
wenzelm@47809
  1413
    lift_definition command to work with the type.
wenzelm@47809
  1414
wenzelm@47809
  1415
  - Usage examples: See Quotient_Examples/Lift_DList.thy,
huffman@47851
  1416
    Quotient_Examples/Lift_RBT.thy, Quotient_Examples/Lift_FSet.thy,
huffman@47851
  1417
    Word/Word.thy and Library/Float.thy.
wenzelm@47809
  1418
wenzelm@47809
  1419
* Quotient package:
wenzelm@47809
  1420
wenzelm@47809
  1421
  - The 'quotient_type' command now supports a 'morphisms' option with
wenzelm@47809
  1422
    rep and abs functions, similar to typedef.
wenzelm@47809
  1423
wenzelm@47809
  1424
  - 'quotient_type' sets up new types to work with the Lifting and
wenzelm@47809
  1425
    Transfer packages, as with 'setup_lifting'.
wenzelm@47809
  1426
wenzelm@47809
  1427
  - The 'quotient_definition' command now requires the user to prove a
wenzelm@47809
  1428
    respectfulness property at the point where the constant is
wenzelm@47809
  1429
    defined, similar to lift_definition; INCOMPATIBILITY.
wenzelm@47809
  1430
wenzelm@47809
  1431
  - Renamed predicate 'Quotient' to 'Quotient3', and renamed theorems
wenzelm@47809
  1432
    accordingly, INCOMPATIBILITY.
wenzelm@47809
  1433
wenzelm@47809
  1434
* New diagnostic command 'find_unused_assms' to find potentially
wenzelm@47809
  1435
superfluous assumptions in theorems using Quickcheck.
wenzelm@47809
  1436
wenzelm@47809
  1437
* Quickcheck:
wenzelm@47809
  1438
wenzelm@47809
  1439
  - Quickcheck returns variable assignments as counterexamples, which
wenzelm@47809
  1440
    allows to reveal the underspecification of functions under test.
wenzelm@47809
  1441
    For example, refuting "hd xs = x", it presents the variable
wenzelm@47809
  1442
    assignment xs = [] and x = a1 as a counterexample, assuming that
wenzelm@47809
  1443
    any property is false whenever "hd []" occurs in it.
wenzelm@47809
  1444
wenzelm@47809
  1445
    These counterexample are marked as potentially spurious, as
wenzelm@47809
  1446
    Quickcheck also returns "xs = []" as a counterexample to the
wenzelm@47809
  1447
    obvious theorem "hd xs = hd xs".
wenzelm@47809
  1448
wenzelm@47809
  1449
    After finding a potentially spurious counterexample, Quickcheck
wenzelm@47809
  1450
    continues searching for genuine ones.
wenzelm@47809
  1451
wenzelm@47809
  1452
    By default, Quickcheck shows potentially spurious and genuine
wenzelm@47809
  1453
    counterexamples. The option "genuine_only" sets quickcheck to only
wenzelm@47809
  1454
    show genuine counterexamples.
wenzelm@47809
  1455
wenzelm@47809
  1456
  - The command 'quickcheck_generator' creates random and exhaustive
wenzelm@47809
  1457
    value generators for a given type and operations.
wenzelm@47809
  1458
wenzelm@47809
  1459
    It generates values by using the operations as if they were
wenzelm@47809
  1460
    constructors of that type.
wenzelm@47809
  1461
wenzelm@47809
  1462
  - Support for multisets.
wenzelm@47809
  1463
wenzelm@47809
  1464
  - Added "use_subtype" options.
wenzelm@47809
  1465
wenzelm@47809
  1466
  - Added "quickcheck_locale" configuration to specify how to process
wenzelm@47809
  1467
    conjectures in a locale context.
wenzelm@47809
  1468
wenzelm@47855
  1469
* Nitpick: Fixed infinite loop caused by the 'peephole_optim' option
wenzelm@47855
  1470
and affecting 'rat' and 'real'.
wenzelm@47809
  1471
wenzelm@47809
  1472
* Sledgehammer:
wenzelm@47809
  1473
  - Integrated more tightly with SPASS, as described in the ITP 2012
wenzelm@47809
  1474
    paper "More SPASS with Isabelle".
wenzelm@47809
  1475
  - Made it try "smt" as a fallback if "metis" fails or times out.
wenzelm@47809
  1476
  - Added support for the following provers: Alt-Ergo (via Why3 and
wenzelm@47809
  1477
    TFF1), iProver, iProver-Eq.
wenzelm@47809
  1478
  - Sped up the minimizer.
wenzelm@47809
  1479
  - Added "lam_trans", "uncurry_aliases", and "minimize" options.
wenzelm@47809
  1480
  - Renamed "slicing" ("no_slicing") option to "slice" ("dont_slice").
wenzelm@47809
  1481
  - Renamed "sound" option to "strict".
wenzelm@47809
  1482
wenzelm@47855
  1483
* Metis: Added possibility to specify lambda translations scheme as a
wenzelm@47855
  1484
parenthesized argument (e.g., "by (metis (lifting) ...)").
wenzelm@47855
  1485
wenzelm@47855
  1486
* SMT: Renamed "smt_fixed" option to "smt_read_only_certificates".
wenzelm@47855
  1487
wenzelm@47855
  1488
* Command 'try0': Renamed from 'try_methods'. INCOMPATIBILITY.
wenzelm@47809
  1489
wenzelm@47856
  1490
* New "case_product" attribute to generate a case rule doing multiple
wenzelm@47856
  1491
case distinctions at the same time.  E.g.
wenzelm@47856
  1492
wenzelm@47856
  1493
  list.exhaust [case_product nat.exhaust]
wenzelm@47856
  1494
wenzelm@47856
  1495
produces a rule which can be used to perform case distinction on both
wenzelm@47856
  1496
a list and a nat.
wenzelm@47856
  1497
wenzelm@47809
  1498
* New "eventually_elim" method as a generalized variant of the
wenzelm@47855
  1499
eventually_elim* rules.  Supports structured proofs.
wenzelm@47855
  1500
wenzelm@47702
  1501
* Typedef with implicit set definition is considered legacy.  Use
wenzelm@47702
  1502
"typedef (open)" form instead, which will eventually become the
wenzelm@47702
  1503
default.
wenzelm@47702
  1504
wenzelm@47856
  1505
* Record: code generation can be switched off manually with
wenzelm@47856
  1506
wenzelm@47856
  1507
  declare [[record_coden = false]]  -- "default true"
wenzelm@47856
  1508
wenzelm@47856
  1509
* Datatype: type parameters allow explicit sort constraints.
wenzelm@47856
  1510
wenzelm@47855
  1511
* Concrete syntax for case expressions includes constraints for source
wenzelm@47855
  1512
positions, and thus produces Prover IDE markup for its bindings.
wenzelm@47855
  1513
INCOMPATIBILITY for old-style syntax translations that augment the
wenzelm@47855
  1514
pattern notation; e.g. see src/HOL/HOLCF/One.thy for translations of
wenzelm@47855
  1515
one_case.
wenzelm@47855
  1516
wenzelm@47855
  1517
* Clarified attribute "mono_set": pure declaration without modifying
wenzelm@47855
  1518
the result of the fact expression.
wenzelm@47855
  1519
haftmann@46752
  1520
* More default pred/set conversions on a couple of relation operations
wenzelm@47464
  1521
and predicates.  Added powers of predicate relations.  Consolidation
wenzelm@47464
  1522

Generalized theorems INF_INT_eq, INF_INT_eq2, SUP_UN_eq, SUP_UN_eq2.
haftmann@46981
  1532
wenzelm@47464
  1533
See theory "Relation" for examples for making use of pred/set
wenzelm@47464

simpler, and more scalable.  Requires a proof bundle, which is
wenzelm@47855
  1924
available as an external component.  Discontinued old (and mostly

wenzelm@47809
  1974
machine word equalities and inequalities into logical circuits,
wenzelm@47809
  1975
defined in HOL/Word/WordBitwise.thy.  Supports addition, subtraction,
wenzelm@47809
  1976
multiplication, shifting by constants, bitwise operators and numeric
wenzelm@47809
  1977
constants.  Requires fixed-length word types, not 'a word.  Solves
wenzelm@47854
  1978
many standard word identities outright and converts more into first

  1979
order problems amenable to blast or similar.  See also examples in

  1983
represent measures, this replaces the records 'a algebra and 'a
wenzelm@47807

measure_space.  The locales based on subset_class now have two
wenzelm@47856

locale-parameters the space \<Omega> and the set of measurable sets M.

The product of probability spaces uses now the same constant as the
wenzelm@47856
  1987
finite product of sigma-finite measure spaces "PiM :: ('i => 'a)
wenzelm@47807
  1988
measure".  Most constants are defined now outside of locales and gain
wenzelm@47807
  1989
an additional parameter, like null_sets, almost_eventually or \<mu>'.
wenzelm@47807
  1990
Measure space constructions for distributions and densities now got
wenzelm@47807
  1991
their own constants distr and density.  Instead of using locales to
wenzelm@47807
  1992
describe measure spaces with a finite space, the measure count_space
wenzelm@47807
  1993
and point_measure is introduced.  INCOMPATIBILITY.

* Antiquotation @{keyword "name"} produces a parser for outer syntax

from a minor keyword introduced via theory header declaration.
wenzelm@46948
  2178
wenzelm@46961

Outer_Syntax.command_spec from a major keyword introduced via theory
wenzelm@46961
  2181
header declaration; it can be passed to Outer_Syntax.command etc.
wenzelm@46961

wenzelm@46992
  2185
/ Attrib.empty_binding, the result is not registered as user-level
wenzelm@46992
  2186
fact.  The Local_Theory.define_internal variant allows to specify a
wenzelm@46992
  2187
non-empty name (used for the foundation in the background theory),
wenzelm@46992
  2188
while omitting the fact binding in the user-context.  Potential
wenzelm@46992
  2189
INCOMPATIBILITY for derived definitional packages: need to specify
wenzelm@46992
  2190
naming policy for primitive definitions more explicitly.
wenzelm@46916
  2191
wenzelm@46497
  2192
* Renamed Thm.capply to Thm.apply, and Thm.cabs to Thm.lambda in

  2193
conformance with similar operations in structure Term and Logic.
wenzelm@46497
  2194
wenzelm@45592
  2195
* Antiquotation @{attributes [...]} embeds attribute source
wenzelm@45592
  2196
representation into the ML text, which is particularly useful with
wenzelm@45592
  2197
declarations like Local_Theory.note.

wenzelm@45293
  2202

* USER_HOME settings variable points to cross-platform user home
wenzelm@47661
  2225
directory, which coincides with HOME on POSIX systems only.  Likewise,
wenzelm@47661
  2226
the Isabelle path specification "~" now expands to $USER_HOME, instead
wenzelm@47661
  2227
of former $HOME.  A different default for USER_HOME may be set
wenzelm@47661
  2228
explicitly in shell environment, before Isabelle settings are
wenzelm@47661
  2229
evaluated.  Minor INCOMPATIBILITY: need to adapt Isabelle path where
wenzelm@47661
  2230
the generic user home was intended.
wenzelm@47661
  2231
wenzelm@47807
  2232
* ISABELLE_HOME_WINDOWS refers to ISABELLE_HOME in windows file name

  2233
notation, which is useful for the jEdit file browser, for example.
wenzelm@47807
  2234

*** General ***
wenzelm@41703
  2244
wenzelm@44760
  2245
* Improved Isabelle/jEdit Prover IDE (PIDE), which can be invoked as
wenzelm@44968
  2246
"isabelle jedit" or "ISABELLE_HOME/Isabelle" on the command line.
wenzelm@44760
  2247
wenzelm@44777
  2248
  - Management of multiple theory files directly from the editor
wenzelm@44760
  2249
    buffer store -- bypassing the file-system (no requirement to save
wenzelm@44760
  2250
    files for checking).
wenzelm@44760
  2251
wenzelm@44777
  2252
  - Markup of formal entities within the text buffer, with semantic
wenzelm@44760
  2253
    highlighting, tooltips and hyperlinks to jump to defining source
wenzelm@44760
  2254
    positions.
wenzelm@44760
  2255
wenzelm@44777
  2256
  - Improved text rendering, with sub/superscripts in the source
wenzelm@44777
  2257
    buffer (including support for copy/paste wrt. output panel, HTML
wenzelm@44777
  2258
    theory output and other non-Isabelle text boxes).
wenzelm@44777
  2259
wenzelm@44777
  2260
  - Refined scheduling of proof checking and printing of results,
wenzelm@44760
  2261
    based on interactive editor view.  (Note: jEdit folding and
wenzelm@44760
  2262
    narrowing allows to restrict buffer perspectives explicitly.)
wenzelm@44760
  2263
wenzelm@44777
  2264
  - Reduced CPU performance requirements, usable on machines with few
wenzelm@44760
  2265
    cores.
wenzelm@44760
  2266
wenzelm@44777
  2267
  - Reduced memory requirements due to pruning of unused document
wenzelm@44760
  2268
    versions (garbage collection).

  2271
including some remaining limitations.

* Theory loader: source files are exclusively located via the master
wenzelm@44800
  2274
directory of each theory node (where the .thy file itself resides).
wenzelm@44800
  2275
The global load path (such as src/HOL/Library) has been discontinued.
wenzelm@44800
  2276
Note that the path element ~~ may be used to reference theories in the
wenzelm@44800
  2277
Isabelle home folder -- for instance, "~~/src/HOL/Library/FuncSet".
wenzelm@44800
  2278
INCOMPATIBILITY.
wenzelm@44800
  2279
wenzelm@41955
  2280
* Theory loader: source files are identified by content via SHA1
wenzelm@41955
  2281
digests.  Discontinued former path/modtime identification and optional
wenzelm@41955
  2282
ISABELLE_FILE_IDENT plugin scripts.
wenzelm@41955
  2283
wenzelm@41703
  2284
* Parallelization of nested Isar proofs is subject to
wenzelm@41703
  2285
Goal.parallel_proofs_threshold (default 100).  See also isabelle
wenzelm@41703
  2286
usedir option -Q.
wenzelm@41703
  2287
wenzelm@42669
  2288
* Name space: former unsynchronized references are now proper
wenzelm@42669
  2289
configuration options, with more conventional names:
wenzelm@42669
  2290
wenzelm@42669
  2291
  long_names   ~> names_long
wenzelm@42669
  2292
  short_names  ~> names_short
wenzelm@42669
  2293
  unique_names ~> names_unique
wenzelm@42669
  2294
wenzelm@42669
  2295
Minor INCOMPATIBILITY, need to declare options in context like this:
wenzelm@42669
  2296
wenzelm@42669
  2297
  declare [[names_unique = false]]
wenzelm@42358
  2298
wenzelm@42502
  2299
* Literal facts `prop` may contain dummy patterns, e.g. `_ = _`.  Note
wenzelm@42502
  2300
that the result needs to be unique, which means fact specifications
wenzelm@42502
  2301
may have to be refined after enriching a proof context.
wenzelm@42502
  2302
wenzelm@44800
  2303
* Attribute "case_names" has been refined: the assumptions in each case
wenzelm@44800
  2304
can be named now by following the case name with [name1 name2 ...].
wenzelm@44800
  2305
wenzelm@44968
  2306
* Isabelle/Isar reference manual has been updated and extended:
wenzelm@44968
  2307
  - "Synopsis" provides a catalog of main Isar language concepts.
wenzelm@44968
  2308
  - Formal references in syntax diagrams, via @{rail} antiquotation.
wenzelm@44968
  2309
  - Updated material from classic "ref" manual, notably about

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

wenzelm@44973
  2374
INCOMPATIBILITY.
wenzelm@44973
  2375
krauss@44845
  2376
* Added syntactic classes "inf" and "sup" for the respective
krauss@44845
  2377
constants.  INCOMPATIBILITY: Changes in the argument order of the
krauss@44845
  2378
(mostly internal) locale predicates for some derived classes.

UN_ball_bex_simps.  INCOMPATIBILITY.
wenzelm@44800
  2383
wenzelm@44800

  2385
separate type class floor_ceiling.
wenzelm@44800
  2386
wenzelm@44800

wenzelm@44800
  2391
wenzelm@44800

Both use point-free characterization; interpretation proofs may need
wenzelm@44800
  2393
adjustment.  INCOMPATIBILITY.
haftmann@42874
  2394
wenzelm@44800
  2395
* Theory Limits: Type "'a net" has been renamed to "'a filter", in

* Theory Complex_Main: The locale interpretations for the
wenzelm@44800
  2399
bounded_linear and bounded_bilinear locales have been removed, in
wenzelm@44800
  2400
order to reduce the number of duplicate lemmas. Users must use the

* Theory Complex_Main: The definition of infinite series was
wenzelm@44967
  2498
generalized.  Now it is defined on the type class {topological_space,
wenzelm@44967
  2499
comm_monoid_add}.  Hence it is useable also for extended real numbers.
wenzelm@42484
  2500
huffman@44908
  2501
* Theory Complex_Main: The complex exponential function "expi" is now
huffman@44908
  2502
a type-constrained abbreviation for "exp :: complex => complex"; thus
huffman@44908
  2503
several polymorphic lemmas about "exp" are now applicable to "expi".
huffman@44908
  2504
wenzelm@44968
  2505
* Code generation:
wenzelm@44968
  2506
wenzelm@44968
  2507
  - Theory Library/Code_Char_ord provides native ordering of
wenzelm@44968
  2508
    characters in the target language.
wenzelm@44968
  2509
wenzelm@44968
  2510
  - Commands code_module and code_library are legacy, use export_code
wenzelm@44968
  2511
    instead.
wenzelm@44968
  2512
wenzelm@44968
  2513
  - Method "evaluation" is legacy, use method "eval" instead.
wenzelm@44968
  2514
wenzelm@44968
  2515
  - Legacy evaluator "SML" is deactivated by default.  May be
wenzelm@44968
  2516
    reactivated by the following theory command:
wenzelm@44968
  2517
wenzelm@44968
  2518
      setup {* Value.add_evaluator ("SML", Codegen.eval_term) *}
wenzelm@44968
  2519
wenzelm@44968
  2520
* Declare ext [intro] by default.  Rare INCOMPATIBILITY.
wenzelm@44968
  2521
wenzelm@45088
  2522
* New proof method "induction" that gives induction hypotheses the
wenzelm@45088
  2523
name "IH", thus distinguishing them from further hypotheses that come
wenzelm@45088
  2524
from rule induction.  The latter are still called "hyps".  Method
wenzelm@45088
  2525
"induction" is a thin wrapper around "induct" and follows the same
wenzelm@45088
  2526
syntax.
wenzelm@45088
  2527
wenzelm@44968
  2528
* Method "fastsimp" has been renamed to "fastforce", but "fastsimp" is
wenzelm@44968
  2529
still available as a legacy feature for some time.
wenzelm@44968
  2530
wenzelm@44968
  2531
* Nitpick:
wenzelm@44968
  2532
  - Added "need" and "total_consts" options.
wenzelm@44968
  2533
  - Reintroduced "show_skolems" option by popular demand.
wenzelm@44968
  2534
  - Renamed attribute: nitpick_def ~> nitpick_unfold.
wenzelm@44968
  2535
    INCOMPATIBILITY.
wenzelm@44968
  2536
wenzelm@44968
  2537
* Sledgehammer:
wenzelm@44968
  2538
  - Use quasi-sound (and efficient) translations by default.
wenzelm@44968
  2539
  - Added support for the following provers: E-ToFoF, LEO-II,
wenzelm@44968
  2540
    Satallax, SNARK, Waldmeister, and Z3 with TPTP syntax.
wenzelm@44968
  2541
  - Automatically preplay and minimize proofs before showing them if
wenzelm@44968
  2542
    this can be done within reasonable time.
wenzelm@44968
  2543
  - sledgehammer available_provers ~> sledgehammer supported_provers.
wenzelm@44968
  2544
    INCOMPATIBILITY.
wenzelm@44968
  2545
  - Added "preplay_timeout", "slicing", "type_enc", "sound",
wenzelm@44968
  2546
    "max_mono_iters", and "max_new_mono_instances" options.
wenzelm@44968
  2547
  - Removed "explicit_apply" and "full_types" options as well as "Full
wenzelm@44968
  2548
    Types" Proof General menu item. INCOMPATIBILITY.
wenzelm@44968
  2549
wenzelm@44968
  2550
* Metis:
wenzelm@44968
  2551
  - Removed "metisF" -- use "metis" instead. INCOMPATIBILITY.
wenzelm@44968
  2552
  - Obsoleted "metisFT" -- use "metis (full_types)" instead.
wenzelm@44968
  2553
    INCOMPATIBILITY.
wenzelm@44968
  2554
wenzelm@44968
  2555
* Command 'try':
wenzelm@44968
  2556
  - Renamed 'try_methods' and added "simp:", "intro:", "dest:", and
wenzelm@44968
  2557
    "elim:" options. INCOMPATIBILITY.
wenzelm@44968
  2558
  - Introduced 'try' that not only runs 'try_methods' but also
wenzelm@44968
  2559
    'solve_direct', 'sledgehammer', 'quickcheck', and 'nitpick'.
wenzelm@44968
  2560
wenzelm@44968
  2561
* Quickcheck:
wenzelm@44968
  2562
  - Added "eval" option to evaluate terms for the found counterexample
wenzelm@44968
  2563
    (currently only supported by the default (exhaustive) tester).
wenzelm@44968
  2564
  - Added post-processing of terms to obtain readable counterexamples
wenzelm@44968
  2565
    (currently only supported by the default (exhaustive) tester).
wenzelm@44968
  2566
  - New counterexample generator quickcheck[narrowing] enables
wenzelm@44968
  2567
    narrowing-based testing.  Requires the Glasgow Haskell compiler
wenzelm@44968
  2568
    with its installation location defined in the Isabelle settings
wenzelm@44968
  2569
    environment as ISABELLE_GHC.
wenzelm@44968
  2570
  - Removed quickcheck tester "SML" based on the SML code generator
wenzelm@44968
  2571
    (formly in HOL/Library).
wenzelm@44968
  2572
wenzelm@44968
  2573
* Function package: discontinued option "tailrec".  INCOMPATIBILITY,
wenzelm@44968
  2574
use 'partial_function' instead.
wenzelm@44968
  2575
wenzelm@44968
  2576
* Theory Library/Extended_Reals replaces now the positive extended
wenzelm@44968
  2577
reals found in probability theory. This file is extended by
wenzelm@44968
  2578
Multivariate_Analysis/Extended_Real_Limits.
wenzelm@44968
  2579
wenzelm@44974
  2580
* Theory Library/Old_Recdef: old 'recdef' package has been moved here,
wenzelm@44974
  2581
from where it must be imported explicitly if it is really required.
wenzelm@44974
  2582
INCOMPATIBILITY.
wenzelm@44968
  2583
wenzelm@44968
  2584
* Theory Library/Wfrec: well-founded recursion combinator "wfrec" has
wenzelm@44968
  2585
been moved here.  INCOMPATIBILITY.
wenzelm@44968
  2586
wenzelm@44968
  2587
* Theory Library/Saturated provides type of numbers with saturated
wenzelm@44968
  2588
arithmetic.
wenzelm@44968
  2589
wenzelm@44968
  2590
* Theory Library/Product_Lattice defines a pointwise ordering for the
wenzelm@44968
  2591
product type 'a * 'b, and provides instance proofs for various order
wenzelm@44968
  2592
and lattice type classes.
wenzelm@44968
  2593
wenzelm@44968
  2594
* Theory Library/Countable now provides the "countable_datatype" proof
wenzelm@44968
  2595
method for proving "countable" class instances for datatypes.
wenzelm@44968
  2596
wenzelm@44968
  2597
* Theory Library/Cset_Monad allows do notation for computable sets
wenzelm@44968
  2598
(cset) via the generic monad ad-hoc overloading facility.
wenzelm@44968
  2599
wenzelm@44968
  2600
* Library: Theories of common data structures are split into theories
wenzelm@44968
  2601
for implementation, an invariant-ensuring type, and connection to an
wenzelm@44968
  2602
abstract type. INCOMPATIBILITY.
wenzelm@44968
  2603
wenzelm@44968
  2604
  - RBT is split into RBT and RBT_Mapping.
wenzelm@44968
  2605
  - AssocList is split and renamed into AList and AList_Mapping.
wenzelm@44968

wenzelm@44968
  2609
* Theory Library/Nat_Infinity has been renamed to
wenzelm@44968
  2610
Library/Extended_Nat, with name changes of the following types and
wenzelm@44968
  2611

wenzelm@44968
  2619
Every theorem name containing "inat", "Fin", "Infty", or "iSuc" has
wenzelm@44968
  2620
been renamed accordingly. INCOMPATIBILITY.

fixes a constant "Basis :: 'a set" consisting of the standard
wenzelm@44968
  2624
orthonormal basis for the type. Users now have the option of
wenzelm@44968
  2625
quantifying over this set instead of using the "basis" function, e.g.
wenzelm@44968
  2626
"ALL x:Basis. P x" vs "ALL i<DIM('a). P (basis i)".

* Session Multivariate_Analysis: Type "('a, 'b) cart" has been renamed
wenzelm@44968
  2629
to "('a, 'b) vec" (the syntax "'a ^ 'b" remains unaffected). Constants
wenzelm@44968
  2630
"Cart_nth" and "Cart_lambda" have been respectively renamed to
wenzelm@44968
  2631
"vec_nth" and "vec_lambda"; theorems mentioning those names have
wenzelm@44968
  2632
changed to match. Definition theorems for overloaded constants now use
wenzelm@44968
  2633
the standard "foo_vec_def" naming scheme. A few other theorems have
wenzelm@44968
  2634
been renamed as follows (INCOMPATIBILITY):

* Session Multivariate_Analysis: Several duplicate theorems have been

removed, and other theorems have been renamed or replaced with more
wenzelm@44968
  2643
general versions. INCOMPATIBILITY.
