*** General ***
wenzelm@57941
    11
wenzelm@59939
    12
* Local theory specification commands may have a 'private' or
wenzelm@59990
    13
'qualified' modifier to restrict name space accesses to the local scope,
wenzelm@59939
    14
as provided by some "context begin ... end" block. For example:
wenzelm@59926
    15
wenzelm@59926
    16
  context
wenzelm@59926
    17
  begin
wenzelm@59926
    18
wenzelm@59926
    19
  private definition ...
wenzelm@59926
    20
  private lemma ...
wenzelm@59926
    21
wenzelm@59990
    22
  qualified definition ...
wenzelm@59990
    23
  qualified lemma ...
wenzelm@59990
    24
wenzelm@59926
    25
  lemma ...
wenzelm@59926
    26
  theorem ...
wenzelm@59926
    27
wenzelm@59926
    28
  end
wenzelm@59926
    29
wenzelm@59901
    30
* Command 'experiment' opens an anonymous locale context with private
wenzelm@59901
    31
naming policy.
wenzelm@59901
    32
wenzelm@59951
    33
* Command 'notepad' requires proper nesting of begin/end and its proof
wenzelm@59951
    34
structure in the body: 'oops' is no longer supported here. Minor
wenzelm@59951
    35
INCOMPATIBILITY, use 'sorry' instead.
wenzelm@59951
    36
wenzelm@59951
    37
* Command 'named_theorems' declares a dynamic fact within the context,
wenzelm@59951
    38
together with an attribute to maintain the content incrementally. This
wenzelm@59951
    39
supersedes functor Named_Thms in Isabelle/ML, but with a subtle change
wenzelm@59951
    40
of semantics due to external visual order vs. internal reverse order.
wenzelm@59951
    41
wenzelm@59951
    42
* 'find_theorems': search patterns which are abstractions are
wenzelm@59951
    43
schematically expanded before search. Search results match the naive
wenzelm@59951
    44
expectation more closely, particularly wrt. abbreviations.
wenzelm@59951
    45
INCOMPATIBILITY.
wenzelm@59648
    46
wenzelm@59569
    47
* Commands 'method_setup' and 'attribute_setup' now work within a local
wenzelm@59569
    48
theory context.
wenzelm@57941
    49
wenzelm@58928
    50
* Outer syntax commands are managed authentically within the theory
wenzelm@59569
    51
context, without implicit global state. Potential for accidental
wenzelm@58928
    52
INCOMPATIBILITY, make sure that required theories are really imported.
wenzelm@58928
    53
wenzelm@59951
    54
* Structural composition of proof methods (meth1; meth2) in Isar
wenzelm@59951
    55
corresponds to (tac1 THEN_ALL_NEW tac2) in ML.
haftmann@59105
    56
wenzelm@57941
    57
wenzelm@58524
    58
*** Prover IDE -- Isabelle/Scala/jEdit ***
wenzelm@58524
    59
wenzelm@59569
    60
* Improved folding mode "isabelle" based on Isar syntax. Alternatively,
wenzelm@59569
    61
the "sidekick" mode may be used for document structure.
wenzelm@59569
    62
wenzelm@59569
    63
* Extended bracket matching based on Isar language structure. System
wenzelm@59569
    64
option jedit_structure_limit determines maximum number of lines to scan
wenzelm@59569
    65
in the buffer.
wenzelm@58758
    66
wenzelm@58540
    67
* Support for BibTeX files: context menu, context-sensitive token
wenzelm@58540
    68
marker, SideKick parser.
wenzelm@58524
    69
wenzelm@58551
    70
* Document antiquotation @{cite} provides formal markup, which is
wenzelm@58551
    71
interpreted semi-formally based on .bib files that happen to be opened
wenzelm@58592
    72
in the editor (hyperlinks, completion etc.).
wenzelm@58551
    73
wenzelm@58785
    74
* Less waste of vertical space via negative line spacing (see Global
wenzelm@58785
    75
Options / Text Area).
wenzelm@58785
    76
wenzelm@60089
    77
* Improved graphview panel with optional output of PNG or PDF, for
wenzelm@60089
    78
display of 'thy_deps', 'locale_deps', 'class_deps' etc.
wenzelm@60009
    79
wenzelm@60093
    80
* Command 'thy_deps' allows optional bounds, analogously to
wenzelm@60093
    81
'class_deps'.
wenzelm@60093
    82
wenzelm@60072
    83
* Improved scheduling for asynchronous print commands (e.g. provers
wenzelm@60072
    84
managed by the Sledgehammer panel) wrt. ongoing document processing.
wenzelm@60072
    85
wenzelm@58524
    86
wenzelm@59951
    87
*** Document preparation ***
wenzelm@59951
    88
wenzelm@59951
    89
* Document markup commands 'chapter', 'section', 'subsection',
wenzelm@59951
    90
'subsubsection', 'text', 'txt', 'text_raw' work uniformly in any
wenzelm@59951
    91
context, even before the initial 'theory' command. Obsolete proof
wenzelm@59951
    92
commands 'sect', 'subsect', 'subsubsect', 'txt_raw' have been
wenzelm@59951
    93
discontinued, use 'section', 'subsection', 'subsubsection', 'text_raw'
wenzelm@59951
    94
instead. The old 'header' command is still retained for some time, but
wenzelm@59951
    95
should be replaced by 'chapter', 'section' etc. (using "isabelle
wenzelm@59951
    96
update_header"). Minor INCOMPATIBILITY.
wenzelm@59951
    97
wenzelm@60009
    98
* Official support for "tt" style variants, via \isatt{...} or
wenzelm@60009
    99
\begin{isabellett}...\end{isabellett}. The somewhat fragile \verb or
wenzelm@60009
   100
verbatim environment of LaTeX is no longer used. This allows @{ML} etc.
wenzelm@60009
   101
as argument to other macros (such as footnotes).
wenzelm@60009
   102
wenzelm@60009
   103
* Document antiquotation @{verbatim} prints ASCII text literally in "tt"
wenzelm@60009
   104
style.
wenzelm@60009
   105
wenzelm@60009
   106
* Discontinued obsolete option "document_graph": session_graph.pdf is
wenzelm@60009
   107
produced unconditionally for HTML browser_info and PDF-LaTeX document.
wenzelm@60009
   108
wenzelm@59951
   109
* Diagnostic commands and document markup commands within a proof do not
wenzelm@59951
   110
affect the command tag for output. Thus commands like 'thm' are subject
wenzelm@59951
   111
to proof document structure, and no longer "stick out" accidentally.
wenzelm@59951
   112
Commands 'text' and 'txt' merely differ in the LaTeX style, not their
wenzelm@59951
   113
tags. Potential INCOMPATIBILITY in exotic situations.
wenzelm@59951
   114
wenzelm@59951
   115
* System option "pretty_margin" is superseded by "thy_output_margin",
wenzelm@59951
   116
which is also accessible via document antiquotation option "margin".
wenzelm@59951
   117
Only the margin for document output may be changed, but not the global
wenzelm@59951
   118
pretty printing: that is 76 for plain console output, and adapted
wenzelm@59951
   119
dynamically in GUI front-ends. Implementations of document
wenzelm@59951
   120
antiquotations need to observe the margin explicitly according to
wenzelm@59951
   121
Thy_Output.string_of_margin. Minor INCOMPATIBILITY.
wenzelm@59951
   122

haftmann@58202
   124
*** Pure ***
haftmann@58202
   125
wenzelm@59835
   126
* Proof methods with explicit instantiation ("rule_tac", "subgoal_tac"
wenzelm@59835
   127
etc.) allow an optional context of local variables ('for' declaration):
wenzelm@59835
   128
these variables become schematic in the instantiated theorem; this
wenzelm@59835
   129
behaviour is analogous to 'for' in attributes "where" and "of".
wenzelm@59835
   130
Configuration option rule_insts_schematic (default false) controls use
wenzelm@59835
   131
of schematic variables outside the context. Minor INCOMPATIBILITY,
wenzelm@59835
   132
declare rule_insts_schematic = true temporarily and update to use local
wenzelm@59835
   133
variable declarations or dummy patterns instead.
wenzelm@59835
   134
wenzelm@60009
   135
* Explicit instantiation via attributes "where", "of", and proof methods
wenzelm@60009
   136
"rule_tac" with derivatives like "subgoal_tac" etc. admit dummy patterns
wenzelm@60009
   137
("_") that stand for anonymous local variables.
wenzelm@60009
   138
wenzelm@59951
   139
* Generated schematic variables in standard format of exported facts are
wenzelm@59951
   140
incremented to avoid material in the proof context. Rare
wenzelm@59951
   141
INCOMPATIBILITY, explicit instantiation sometimes needs to refer to
wenzelm@59951
   142
different index.
wenzelm@59951
   143
wenzelm@60009
   144
* Command "class_deps" takes optional sort arguments to constrain then
wenzelm@60009
   145
resulting class hierarchy.
haftmann@58202
   146
wenzelm@60010
   147
* Lexical separation of signed and unsigned numerals: categories "num"
wenzelm@60010
   148
and "float" are unsigned. INCOMPATIBILITY: subtle change in precedence
wenzelm@60010
   149
of numeral signs, particularly in expressions involving infix syntax
wenzelm@60010
   150
like "(- 1) ^ n".
haftmann@58410
   151
wenzelm@58421
   152
* Old inner token category "xnum" has been discontinued.  Potential
wenzelm@58421
   153
INCOMPATIBILITY for exotic syntax: may use mixfix grammar with "num"
wenzelm@58421
   154
token category instead.
wenzelm@58421

*** HOL ***
blanchet@57737
   158
blanchet@57983
   159
* New (co)datatype package:
blanchet@58373
   160
  - The 'datatype_new' command has been renamed 'datatype'. The old
blanchet@58373
   161
    command of that name is now called 'old_datatype' and is provided
blanchet@58373
   162
    by "~~/src/HOL/Library/Old_Datatype.thy". See
blanchet@58373
   163
    'isabelle doc datatypes' for information on porting.
blanchet@58373
   164
    INCOMPATIBILITY.
blanchet@57983
   165
  - Renamed theorems:
blanchet@57983
   166
      disc_corec ~> corec_disc
blanchet@57983
   167
      disc_corec_iff ~> corec_disc_iff

blanchet@57983
   178
      weak_case_cong ~> case_cong_weak
blanchet@57983
   179
    INCOMPATIBILITY.
blanchet@58192
   180
  - The "no_code" option to "free_constructors", "datatype_new", and
blanchet@58192
   181
    "codatatype" has been renamed "plugins del: code".
blanchet@58192
   182
    INCOMPATIBILITY.
blanchet@58044
   183
  - The rules "set_empty" have been removed. They are easy
blanchet@58044
   184
    consequences of other set rules "by auto".
blanchet@58044
   185
    INCOMPATIBILITY.
blanchet@58044
   186
  - The rule "set_cases" is now registered with the "[cases set]"
blanchet@57990
   187
    attribute. This can influence the behavior of the "cases" proof
blanchet@57990
   188
    method when more than one case rule is applicable (e.g., an
blanchet@57990
   189
    assumption is of the form "w : set ws" and the method "cases w"
blanchet@57990
   190
    is invoked). The solution is to specify the case rule explicitly
blanchet@57990
   191
    (e.g. "cases w rule: widget.exhaust").
blanchet@57990
   192
    INCOMPATIBILITY.
blanchet@59675
   193
  - Renamed theories:
blanchet@59675
   194
      BNF_Comp ~> BNF_Composition
blanchet@59675
   195
      BNF_FP_Base ~> BNF_Fixpoint_Base

   198
      BNF_Constructions_on_Wellorders ~> BNF_Wellorder_Constructions
blanchet@59675
   199
      Cardinals/Constructions_on_Wellorders ~> Cardinals/Wellorder_Constructions
blanchet@59675
   200
    INCOMPATIBILITY.
blanchet@57983
   201
blanchet@57983
   202
* Old datatype package:
blanchet@58310
   203
  - The old 'datatype' command has been renamed 'old_datatype', and
blanchet@58373
   204
    'rep_datatype' has been renamed 'old_rep_datatype'. They are
blanchet@58373
   205
    provided by "~~/src/HOL/Library/Old_Datatype.thy". See
blanchet@58310
   206
    'isabelle doc datatypes' for information on porting.
blanchet@58373
   207
    INCOMPATIBILITY.
blanchet@57983
   208
  - Renamed theorems:
blanchet@57983
   209
      weak_case_cong ~> case_cong_weak
blanchet@57983
   210
    INCOMPATIBILITY.
blanchet@58373
   211
  - Renamed theory:
blanchet@58373
   212
      ~~/src/HOL/Datatype.thy ~> ~~/src/HOL/Library/Old_Datatype.thy
blanchet@58373
   213
    INCOMPATIBILITY.
blanchet@57983
   214
blanchet@59039
   215
* Nitpick:
wenzelm@60010
   216
  - Fixed soundness bug related to the strict and non-strict subset
blanchet@59039
   217
    operations.
blanchet@59039
   218
blanchet@57737
   219
* Sledgehammer:
blanchet@59511
   220
  - CVC4 is now included with Isabelle instead of CVC3 and run by
blanchet@59511
   221
    default.
blanchet@59965
   222
  - Z3 is now always enabled by default, now that it is fully open
blanchet@59965
   223
    source. The "z3_non_commercial" option is discontinued.
blanchet@57737
   224
  - Minimization is now always enabled by default.
wenzelm@60010
   225
    Removed sub-command:
blanchet@57737
   226
      min
blanchet@59967
   227
  - Proof reconstruction, both one-liners and Isar, has been
blanchet@59039
   228
    dramatically improved.
blanchet@59039
   229
  - Improved support for CVC4 and veriT.
blanchet@57737
   230
blanchet@58062
   231
* Old and new SMT modules:
blanchet@58067
   232
  - The old 'smt' method has been renamed 'old_smt' and moved to
wenzelm@59569
   233
    'src/HOL/Library/Old_SMT.thy'. It is provided for compatibility,
wenzelm@59569
   234
    until applications have been ported to use the new 'smt' method. For
wenzelm@59569
   235
    the method to work, an older version of Z3 (e.g. Z3 3.2 or 4.0) must
wenzelm@59569
   236
    be installed, and the environment variable "OLD_Z3_SOLVER" must
wenzelm@59569
   237
    point to it.
blanchet@58062
   238
    INCOMPATIBILITY.
blanchet@58067
   239
  - The 'smt2' method has been renamed 'smt'.
blanchet@58060
   240
    INCOMPATIBILITY.
wenzelm@59569
   241
  - New option 'smt_reconstruction_step_timeout' to limit the
wenzelm@59569
   242
    reconstruction time of Z3 proof steps in the new 'smt' method.
boehmes@59216
   243
  - New option 'smt_statistics' to display statistics of the new 'smt'
boehmes@59216
   244
    method, especially runtime statistics of Z3 proof reconstruction.
blanchet@58060
   245
wenzelm@60009
   246
* Command and antiquotation "value" provide different evaluation slots
wenzelm@60009
   247
(again), where the previous strategy (NBE after ML) serves as default.
wenzelm@60009
   248
Minor INCOMPATIBILITY.
wenzelm@60009
   249
wenzelm@60009
   250
* Add NO_MATCH-simproc, allows to check for syntactic non-equality.
wenzelm@60009
   251
wenzelm@60009
   252
* field_simps: Use NO_MATCH-simproc for distribution rules, to avoid
wenzelm@60009
   253
non-termination in case of distributing a division. With this change
wenzelm@60009
   254
field_simps is in some cases slightly less powerful, if it fails try to
wenzelm@60009
   255
add algebra_simps, or use divide_simps. Minor INCOMPATIBILITY.
wenzelm@60009
   256
wenzelm@60009
   257
* Separate class no_zero_divisors has been given up in favour of fully
wenzelm@60009
   258
algebraic semiring_no_zero_divisors. INCOMPATIBILITY.
wenzelm@60009
   259
wenzelm@60009
   260
* Class linordered_semidom really requires no zero divisors.
wenzelm@60009
   261
INCOMPATIBILITY.
wenzelm@60009
   262
wenzelm@60009
   263
* Classes division_ring, field and linordered_field always demand
wenzelm@60009
   264
"inverse 0 = 0". Given up separate classes division_ring_inverse_zero,
wenzelm@60009
   265
field_inverse_zero and linordered_field_inverse_zero. INCOMPATIBILITY.
wenzelm@60009
   266
wenzelm@60009
   267
* Classes cancel_ab_semigroup_add / cancel_monoid_add specify explicit
wenzelm@60009
   268
additive inverse operation. INCOMPATIBILITY.
wenzelm@60009
   269
lp15@60020
   270
* Complex powers and square roots. The functions "ln" and "powr" are now
wenzelm@60025
   271
overloaded for types real and complex, and 0 powr y = 0 by definition.
wenzelm@60025
   272
INCOMPATIBILITY: type constraints may be necessary.
lp15@60020
   273
wenzelm@60009
   274
* The functions "sin" and "cos" are now defined for any type of sort
wenzelm@60009
   275
"{real_normed_algebra_1,banach}" type, so in particular on "real" and
wenzelm@60009
   276
"complex" uniformly. Minor INCOMPATIBILITY: type constraints may be
wenzelm@60009
   277
needed.
wenzelm@60009
   278
wenzelm@60009
   279
* New library of properties of the complex transcendental functions sin,
wenzelm@60009
   280
cos, tan, exp, Ln, Arctan, Arcsin, Arccos. Ported from HOL Light.
wenzelm@60009
   281
wenzelm@60009
   282
* The factorial function, "fact", now has type "nat => 'a" (of a sort
wenzelm@60009
   283
that admits numeric types including nat, int, real and complex.
wenzelm@60009
   284
INCOMPATIBILITY: an expression such as "fact 3 = 6" may require a type
wenzelm@60009
   285
constraint, and the combination "real (fact k)" is likely to be
wenzelm@60009
   286
unsatisfactory. If a type conversion is still necessary, then use
wenzelm@60009
   287
"of_nat (fact k)" or "real_of_nat (fact k)".
wenzelm@60009
   288
wenzelm@60009
   289
* Removed functions "natfloor" and "natceiling", use "nat o floor" and
wenzelm@60009
   290
"nat o ceiling" instead. A few of the lemmas have been retained and
wenzelm@60009
   291
adapted: in their names "natfloor"/"natceiling" has been replaced by
wenzelm@60009
   292
"nat_floor"/"nat_ceiling".
wenzelm@60009
   293
wenzelm@60009
   294
* Qualified some duplicated fact names required for boostrapping the
wenzelm@60009
   295
type class hierarchy:
wenzelm@60009
   296
  ab_add_uminus_conv_diff ~> diff_conv_add_uminus
wenzelm@60009
   297
  field_inverse_zero ~> inverse_zero
wenzelm@60009
   298
  field_divide_inverse ~> divide_inverse
wenzelm@60009

wenzelm@60009
   300
Minor INCOMPATIBILITY.
wenzelm@60009
   301
wenzelm@60009
   302
* Eliminated fact duplicates:
wenzelm@60009
   303
  mult_less_imp_less_right ~> mult_right_less_imp_less
wenzelm@60009
   304
  mult_less_imp_less_left ~> mult_left_less_imp_less
wenzelm@60009
   305
Minor INCOMPATIBILITY.
wenzelm@60009
   306
wenzelm@60009
   307
* Fact consolidation: even_less_0_iff is subsumed by
wenzelm@60009
   308
double_add_less_zero_iff_single_add_less_zero (simp by default anyway).
wenzelm@60009
   309
wenzelm@60009
   310
* Generalized and consolidated some theorems concerning divsibility:
wenzelm@60009
   311
  dvd_reduce ~> dvd_add_triv_right_iff
wenzelm@60009
   312
  dvd_plus_eq_right ~> dvd_add_right_iff
wenzelm@60009
   313
  dvd_plus_eq_left ~> dvd_add_left_iff
wenzelm@60009
   314
Minor INCOMPATIBILITY.
wenzelm@60009
   315
wenzelm@60009
   316
* "even" and "odd" are mere abbreviations for "2 dvd _" and "~ 2 dvd _"
wenzelm@60009
   317
and part of theory Main.
wenzelm@60009
   318
  even_def ~> even_iff_mod_2_eq_zero
wenzelm@60009
   319
INCOMPATIBILITY.
wenzelm@60009
   320
wenzelm@60009
   321
* Lemma name consolidation: divide_Numeral1 ~> divide_numeral_1. Minor
wenzelm@60009
   322
INCOMPATIBILITY.
wenzelm@60009
   323
wenzelm@60009
   324
* Bootstrap of listsum as special case of abstract product over lists.
wenzelm@60009
   325
Fact rename:
wenzelm@60009
   326
    listsum_def ~> listsum.eq_foldr

   327
INCOMPATIBILITY.
wenzelm@60009
   328
wenzelm@60009
   329
* Product over lists via constant "listprod".
wenzelm@60009
   330
wenzelm@60009
   331
* Theory List: renamed drop_Suc_conv_tl and nth_drop' to

   332
Cons_nth_drop_Suc.
nipkow@58247
   333
Andreas@58626
   334
* New infrastructure for compiling, running, evaluating and testing
wenzelm@59569
   335
generated code in target languages in HOL/Library/Code_Test. See
wenzelm@59569
   336

   337
wenzelm@60009
   338
* Library/Multiset:
blanchet@59813
   339
  - Introduced "replicate_mset" operation.
blanchet@59813
   340
  - Introduced alternative characterizations of the multiset ordering in
blanchet@59813
   341
    "Library/Multiset_Order".
blanchet@59958
   342
  - Renamed multiset ordering:
blanchet@59958

      \<subseteq># ~> #\<subseteq>#
blanchet@59958
   347
    INCOMPATIBILITY.
blanchet@59986
   348
  - Introduced abbreviations for ill-named multiset operations:
blanchet@59986
   349
      <#, \<subset># abbreviate < (strict subset)
blanchet@59986
   350
      <=#, \<le>#, \<subseteq># abbreviate <= (subset or equal)
blanchet@59986
   351
    INCOMPATIBILITY.
blanchet@59813
   352
  - Renamed
blanchet@59813
   353
      in_multiset_of ~> in_multiset_in_set
nipkow@59998
   354
      Multiset.fold ~> fold_mset
nipkow@59998
   355
      Multiset.filter ~> filter_mset
blanchet@59813
   356
    INCOMPATIBILITY.
nipkow@59949
   357
  - Removed mcard, is equal to size.
blanchet@59813
   358
  - Added attributes:

    INCOMPATIBILITY.
blanchet@59813
   368
wenzelm@60009
   369
* Library/Sum_of_Squares: simplified and improved "sos" method. Always
wenzelm@60009
   370
use local CSDP executable, which is much faster than the NEOS server.
wenzelm@60009
   371
The "sos_cert" functionality is invoked as "sos" with additional
wenzelm@60009
   372
argument. Minor INCOMPATIBILITY.
wenzelm@60009
   373
wenzelm@60009
   374
* HOL-Decision_Procs: New counterexample generator quickcheck
wenzelm@60009
   375
[approximation] for inequalities of transcendental functions. Uses
wenzelm@60009
   376
hardware floating point arithmetic to randomly discover potential
wenzelm@60010
   377
counterexamples. Counterexamples are certified with the "approximation"
wenzelm@60009
   378
method. See HOL/Decision_Procs/ex/Approximation_Quickcheck_Ex.thy for
wenzelm@60009
   379
examples.
immler@58990

hoelzl@59354
   381
* HOL-Probability: Reworked measurability prover
wenzelm@60010
   382
  - applies destructor rules repeatedly
hoelzl@59354
   383
  - removed application splitting (replaced by destructor rule)
wenzelm@59569
   384
  - added congruence rules to rewrite measure spaces under the sets
wenzelm@59569
   385
    projection
wenzelm@59569
   386
wenzelm@60009
   387
* New proof method "rewrite" (in theory ~~/src/HOL/Library/Rewrite) for
wenzelm@60009
   388
single-step rewriting with subterm selection based on patterns.

   391
*** ML ***
blanchet@58066
   392
wenzelm@60009
   393
* Subtle change of name space policy: undeclared entries are now
wenzelm@60009
   394
considered inaccessible, instead of accessible via the fully-qualified
wenzelm@60009
   395
internal name. This mainly affects Name_Space.intern (and derivatives),
wenzelm@60009
   396
which may produce an unexpected Long_Name.hidden prefix. Note that
wenzelm@60010
   397
contemporary applications use the strict Name_Space.check (and
wenzelm@60009
   398
derivatives) instead, which is not affected by the change. Potential
wenzelm@60009
   399
INCOMPATIBILITY in rare applications of Name_Space.intern.
wenzelm@59951
   400
wenzelm@60094
   401
* Subtle change of error semantics of Toplevel.proof_of: regular user
wenzelm@60094
   402
ERROR instead of internal Toplevel.UNDEF.
wenzelm@60094
   403
wenzelm@59951
   404
* Basic combinators map, fold, fold_map, split_list, apply are available
wenzelm@59951
   405
as parameterized antiquotations, e.g. @{map 4} for lists of quadruples.
wenzelm@59951
   406
wenzelm@59951
   407
* Renamed "pairself" to "apply2", in accordance to @{apply 2}.
wenzelm@59951
   408
INCOMPATIBILITY.
wenzelm@59951
   409
wenzelm@59951
   410
* Former combinators NAMED_CRITICAL and CRITICAL for central critical
wenzelm@59951
   411
sections have been discontinued, in favour of the more elementary
wenzelm@59951
   412
Multithreading.synchronized and its high-level derivative
wenzelm@59951
   413
Synchronized.var (which is usually sufficient in applications). Subtle
wenzelm@59951
   414
INCOMPATIBILITY: synchronized access needs to be atomic and cannot be
wenzelm@59951
   415
nested.
wenzelm@59951
   416
wenzelm@60009
   417
* Synchronized.value (ML) is actually synchronized (as in Scala): subtle
wenzelm@60009
   418
change of semantics with minimal potential for INCOMPATIBILITY.
wenzelm@59899
   419
wenzelm@59621
   420
* The main operations to certify logical entities are Thm.ctyp_of and
wenzelm@59621
   421
Thm.cterm_of with a local context; old-style global theory variants are
wenzelm@59621
   422
available as Thm.global_ctyp_of and Thm.global_cterm_of.
wenzelm@59621
   423
INCOMPATIBILITY.
wenzelm@59621
   424
wenzelm@59582
   425
* Elementary operations in module Thm are no longer pervasive.
wenzelm@59582
   426
INCOMPATIBILITY, need to use qualified Thm.prop_of, Thm.cterm_of,
wenzelm@59582
   427
Thm.term_of etc.
wenzelm@59582
   428
wenzelm@58963
   429
* Proper context for various elementary tactics: assume_tac,
wenzelm@59498
   430
resolve_tac, eresolve_tac, dresolve_tac, forward_tac, match_tac,
wenzelm@59498
   431
compose_tac, Splitter.split_tac etc. INCOMPATIBILITY.
wenzelm@58956
   432
blanchet@58066
   433
* Tactical PARALLEL_ALLGOALS is the most common way to refer to
blanchet@58066
   434
PARALLEL_GOALS.
blanchet@58066
   435
wenzelm@59564
   436
* Goal.prove_multi is superseded by the fully general Goal.prove_common,
wenzelm@59564
   437
which also allows to specify a fork priority.
wenzelm@59564
   438
wenzelm@59936
   439
* Antiquotation @{command_spec "COMMAND"} is superseded by
wenzelm@59936
   440
@{command_keyword COMMAND} (usually without quotes and with PIDE
wenzelm@59936
   441
markup). Minor INCOMPATIBILITY.
wenzelm@59936
   442
wenzelm@60009
   443
* Cartouches within ML sources are turned into values of type
wenzelm@60009
   444
Input.source (with formal position information).

wenzelm@59951
   449
* The Isabelle tool "update_cartouches" changes theory files to use
wenzelm@59951
   450
cartouches instead of old-style {* verbatim *} or `alt_string` tokens.
wenzelm@59951
   451
wenzelm@60106
   452
* The Isabelle tool "build" provides new options -X, -k, -x.
wenzelm@59951
   453
wenzelm@59951
   454
* Discontinued old-fashioned "codegen" tool. Code generation can always
wenzelm@59951
   455
be externally triggered using an appropriate ROOT file plus a
wenzelm@59951
   456
corresponding theory. Parametrization is possible using environment
wenzelm@59951

variables, or ML snippets in the most extreme cases. Minor
wenzelm@59951
   458
INCOMPATIBILITY.
wenzelm@58842
   459
wenzelm@59200
   460
* JVM system property "isabelle.threads" determines size of Scala thread
wenzelm@59200
   461
pool, like Isabelle system option "threads" for ML.
wenzelm@59200
   462
wenzelm@59201
   463
* JVM system property "isabelle.laf" determines the default Swing
wenzelm@59201

wenzelm@59201
   465
menu Global Options / Appearance.

wenzelm@58861
   467
* Historical command-line terminator ";" is no longer accepted.  Minor
wenzelm@58861

*** General ***
wenzelm@54702

wenzelm@57452
   481
* Support for official Standard ML within the Isabelle context.
wenzelm@57452
   482
Command 'SML_file' reads and evaluates the given Standard ML file.
wenzelm@57452
   483
Toplevel bindings are stored within the theory context; the initial
wenzelm@57452
   484
environment is restricted to the Standard ML implementation of
wenzelm@57452
   485
Poly/ML, without the add-ons of Isabelle/ML.  Commands 'SML_import'
wenzelm@57452
   486
and 'SML_export' allow to exchange toplevel bindings between the two
wenzelm@57452
   487
separate environments.  See also ~~/src/Tools/SML/Examples.thy for
wenzelm@57452
   488
some examples.
wenzelm@56499
   489
wenzelm@57504
   490
* Standard tactics and proof methods such as "clarsimp", "auto" and
wenzelm@57504
   491
"safe" now preserve equality hypotheses "x = expr" where x is a free
wenzelm@57504
   492
variable.  Locale assumptions and chained facts containing "x"
wenzelm@57504
   493
continue to be useful.  The new method "hypsubst_thin" and the
wenzelm@57504
   494
configuration option "hypsubst_thin" (within the attribute name space)
wenzelm@57504
   495
restore the previous behavior.  INCOMPATIBILITY, especially where
wenzelm@57504
   496
induction is done after these methods or when the names of free and
wenzelm@57504
   497
bound variables clash.  As first approximation, old proofs may be
wenzelm@57504
   498
repaired by "using [[hypsubst_thin = true]]" in the critical spot.
wenzelm@57504
   499
wenzelm@56232
   500
* More static checking of proof methods, which allows the system to
wenzelm@56232
   501
form a closure over the concrete syntax.  Method arguments should be
wenzelm@56232
   502
processed in the original proof context as far as possible, before
wenzelm@56232
   503
operating on the goal state.  In any case, the standard discipline for
wenzelm@56232
   504
subgoal-addressing needs to be observed: no subgoals or a subgoal
wenzelm@56232
   505
number that is out of range produces an empty result sequence, not an
wenzelm@56232
   506
exception.  Potential INCOMPATIBILITY for non-conformant tactical
wenzelm@56232
   507
proof tools.
wenzelm@56232
   508
wenzelm@57452
   509
* Lexical syntax (inner and outer) supports text cartouches with
wenzelm@57452
   510
arbitrary nesting, and without escapes of quotes etc.  The Prover IDE
wenzelm@57452
   511
supports input via ` (backquote).
wenzelm@57452
   512
wenzelm@57452
   513
* The outer syntax categories "text" (for formal comments and document
wenzelm@57452
   514
markup commands) and "altstring" (for literal fact references) allow
wenzelm@57452
   515
cartouches as well, in addition to the traditional mix of quotations.
wenzelm@57452
   516
wenzelm@57452
   517
* Syntax of document antiquotation @{rail} now uses \<newline> instead
wenzelm@57452
   518
of "\\", to avoid the optical illusion of escaped backslash within
wenzelm@57491
   519
string token.  General renovation of its syntax using text cartouches.
wenzelm@57452
   520
Minor INCOMPATIBILITY.
wenzelm@57452
   521
wenzelm@57452
   522
* Discontinued legacy_isub_isup, which was a temporary workaround for
wenzelm@57452
   523
Isabelle/ML in Isabelle2013-1.  The prover process no longer accepts
wenzelm@57452
   524
old identifier syntax with \<^isub> or \<^isup>.  Potential
wenzelm@57452
   525
INCOMPATIBILITY.
wenzelm@57452
   526
wenzelm@57452
   527
* Document antiquotation @{url} produces markup for the given URL,
wenzelm@57452
   528
which results in an active hyperlink within the text.
wenzelm@57452
   529
wenzelm@57452
   530
* Document antiquotation @{file_unchecked} is like @{file}, but does
wenzelm@57452
   531
not check existence within the file-system.
wenzelm@57452
   532
wenzelm@57452
   533
* Updated and extended manuals: codegen, datatypes, implementation,
wenzelm@57452
   534
isar-ref, jedit, system.

*** Prover IDE -- Isabelle/Scala/jEdit ***
wenzelm@54533
   538
wenzelm@57650
   539
* Improved Document panel: simplified interaction where every single
wenzelm@57452
   540
mouse click (re)opens document via desktop environment or as jEdit
wenzelm@57452
   541
buffer.
wenzelm@57452
   542
wenzelm@57452
   543
* Support for Navigator plugin (with toolbar buttons), with connection
wenzelm@57452
   544
to PIDE hyperlinks.
wenzelm@57452
   545
wenzelm@57452
   546
* Auxiliary files ('ML_file' etc.) are managed by the Prover IDE.
wenzelm@57452
   547
Open text buffers take precedence over copies within the file-system.
wenzelm@57452
   548
wenzelm@57452
   549
* Improved support for Isabelle/ML, with jEdit mode "isabelle-ml" for
wenzelm@57452
   550
auxiliary ML files.
wenzelm@57423
   551
wenzelm@57423
   552
* Improved syntactic and semantic completion mechanism, with simple
wenzelm@57423
   553
templates, completion language context, name-space completion,
wenzelm@57423
   554
file-name completion, spell-checker completion.
wenzelm@57423
   555
wenzelm@57423
   556
* Refined GUI popup for completion: more robust key/mouse event
wenzelm@57423
   557
handling and propagation to enclosing text area -- avoid loosing
wenzelm@57423
   558
keystrokes with slow / remote graphics displays.
wenzelm@57423
   559
wenzelm@57833
   560
* Completion popup supports both ENTER and TAB (default) to select an
wenzelm@57833
   561
item, depending on Isabelle options.
wenzelm@57833
   562
wenzelm@57423
   563
* Refined insertion of completion items wrt. jEdit text: multiple
wenzelm@57423
   564
selections, rectangular selections, rectangular selection as "tall
wenzelm@57423
   565
caret".
wenzelm@56342
   566
wenzelm@56580
   567
* Integrated spell-checker for document text, comments etc. with
wenzelm@57423
   568
completion popup and context-menu.
wenzelm@56554
   569
wenzelm@56879
   570
* More general "Query" panel supersedes "Find" panel, with GUI access
wenzelm@56879
   571
to commands 'find_theorems' and 'find_consts', as well as print
wenzelm@56879
   572
operations for the context.  Minor incompatibility in keyboard
wenzelm@56879
   573
shortcuts etc.: replace action isabelle-find by isabelle-query.
wenzelm@56761
   574
wenzelm@56901
   575
* Search field for all output panels ("Output", "Query", "Info" etc.)
wenzelm@56901
   576
to highlight text via regular expression.
wenzelm@56901
   577
wenzelm@54881
   578
* Option "jedit_print_mode" (see also "Plugin Options / Isabelle /
wenzelm@54881
   579
General") allows to specify additional print modes for the prover
wenzelm@54881
   580
process, without requiring old-fashioned command-line invocation of
wenzelm@54881
   581
"isabelle jedit -m MODE".
wenzelm@54881
   582
wenzelm@56505
   583
* More support for remote files (e.g. http) using standard Java
wenzelm@56505
   584
networking operations instead of jEdit virtual file-systems.
wenzelm@56505
   585
wenzelm@57822
   586
* Empty editors buffers that are no longer required (e.g.\ via theory
wenzelm@57822
   587
imports) are automatically removed from the document model.
wenzelm@57822
   588
wenzelm@57869
   589
* Improved monitor panel.
wenzelm@57869
   590
wenzelm@56838
   591
* Improved Console/Scala plugin: more uniform scala.Console output,
wenzelm@56838
   592
more robust treatment of threads and interrupts.
wenzelm@56838
   593
wenzelm@56939
   594
* Improved management of dockable windows: clarified keyboard focus
wenzelm@56939
   595
and window placement wrt. main editor view; optional menu item to
wenzelm@56939
   596
"Detach" a copy where this makes sense.
wenzelm@56939
   597
wenzelm@57452
   598
* New Simplifier Trace panel provides an interactive view of the
wenzelm@57591
   599
simplification process, enabled by the "simp_trace_new" attribute
wenzelm@57452
   600
within the context.

*** Pure ***
wenzelm@55001
   604
wenzelm@57504
   605
* Low-level type-class commands 'classes', 'classrel', 'arities' have
wenzelm@57504
   606
been discontinued to avoid the danger of non-trivial axiomatization
wenzelm@57504
   607
that is not immediately visible.  INCOMPATIBILITY, use regular
wenzelm@57504
   608
'instance' command with proof.  The required OFCLASS(...) theorem
wenzelm@57504
   609
might be postulated via 'axiomatization' beforehand, or the proof
wenzelm@57504
   610
finished trivially if the underlying class definition is made vacuous
wenzelm@57504
   611
(without any assumptions).  See also Isabelle/ML operations
wenzelm@57504
   612
Axclass.class_axiomatization, Axclass.classrel_axiomatization,
wenzelm@57504
   613
Axclass.arity_axiomatization.
wenzelm@57504
   614
wenzelm@56245
   615
* Basic constants of Pure use more conventional names and are always
wenzelm@56245
   616
qualified.  Rare INCOMPATIBILITY, but with potentially serious
wenzelm@56245
   617
consequences, notably for tools in Isabelle/ML.  The following
wenzelm@56245
   618
renaming needs to be applied:
wenzelm@56245
   619
wenzelm@56245
   620
  ==             ~>  Pure.eq
wenzelm@56245
   621
  ==>            ~>  Pure.imp
wenzelm@56245
   622
  all            ~>  Pure.all
wenzelm@56245
   623
  TYPE           ~>  Pure.type
wenzelm@56245
   624
  dummy_pattern  ~>  Pure.dummy_pattern
wenzelm@56245
   625
wenzelm@56245
   626
Systematic porting works by using the following theory setup on a
wenzelm@56245
   627
*previous* Isabelle version to introduce the new name accesses for the
wenzelm@56245
   628
old constants:
wenzelm@56245
   629
wenzelm@56245
   630
setup {*
wenzelm@56245
   631
  fn thy => thy
wenzelm@56245
   632
    |> Sign.root_path
wenzelm@56245
   633
    |> Sign.const_alias (Binding.qualify true "Pure" @{binding eq}) "=="
wenzelm@56245
   634
    |> Sign.const_alias (Binding.qualify true "Pure" @{binding imp}) "==>"
wenzelm@56245
   635
    |> Sign.const_alias (Binding.qualify true "Pure" @{binding all}) "all"
wenzelm@56245
   636
    |> Sign.restore_naming thy
wenzelm@56245
   637
*}
wenzelm@56245
   638
wenzelm@56245
   639
Thus ML antiquotations like @{const_name Pure.eq} may be used already.
wenzelm@56245
   640
Later the application is moved to the current Isabelle version, and
wenzelm@56245
   641
the auxiliary aliases are deleted.
wenzelm@56245
   642
wenzelm@55143
   643
* Attributes "where" and "of" allow an optional context of local
wenzelm@55143
   644
variables ('for' declaration): these variables become schematic in the
wenzelm@55143
   645
instantiated theorem.
wenzelm@55143
   646
wenzelm@55152
   647
* Obsolete attribute "standard" has been discontinued (legacy since
wenzelm@55152
   648
Isabelle2012).  Potential INCOMPATIBILITY, use explicit 'for' context
wenzelm@55152
   649
where instantiations with schematic variables are intended (for
wenzelm@55152
   650
declaration commands like 'lemmas' or attributes like "of").  The
wenzelm@55152
   651
following temporary definition may help to port old applications:
wenzelm@55152
   652
wenzelm@55152
   653
  attribute_setup standard =
wenzelm@55152
   654
    "Scan.succeed (Thm.rule_attribute (K Drule.export_without_context))"
wenzelm@55152
   655
wenzelm@55001
   656
* More thorough check of proof context for goal statements and
wenzelm@55006
   657
attributed fact expressions (concerning background theory, declared
wenzelm@55006
   658
hyps).  Potential INCOMPATIBILITY, tools need to observe standard
wenzelm@55006
   659
context discipline.  See also Assumption.add_assumes and the more
wenzelm@55006
   660
primitive Thm.assume_hyps.
wenzelm@55001
   661
wenzelm@55108
   662
* Inner syntax token language allows regular quoted strings "..."
wenzelm@55108
   663
(only makes sense in practice, if outer syntax is delimited
wenzelm@57452
   664
differently, e.g. via cartouches).
wenzelm@57452
   665
wenzelm@57504
   666
* Command 'print_term_bindings' supersedes 'print_binds' for clarity,
wenzelm@57504
   667
but the latter is retained some time as Proof General legacy.
wenzelm@57504
   668
wenzelm@57452
   669
* Code generator preprocessor: explicit control of simp tracing on a
wenzelm@57452
   670
per-constant basis.  See attribute "code_preproc".

   676
language requirements.  INCOMPATIBILITY.
wenzelm@57504
   677
wenzelm@57504
   678

wenzelm@57504
   679
INCOMPATIBILITY.
wenzelm@57504
   680
wenzelm@57504

   682
INCOMPATIBILITY.
wenzelm@57504
   683
wenzelm@57504
   684
* Code generation for SML and OCaml: dropped arcane "no_signatures"

   685
option.  Minor INCOMPATIBILITY.
wenzelm@57504
   686
wenzelm@57504
   687
* "declare [[code abort: ...]]" replaces "code_abort ...".

INCOMPATIBILITY.
wenzelm@57504
   689
wenzelm@57504
   690

wenzelm@57504
   691
with the given constants.
wenzelm@57504
   692
wenzelm@57504
   693
* Code generations are provided for make, fields, extend and truncate
wenzelm@57504
   694
operations on records.
haftmann@57437
   695
wenzelm@57452
   696
* Command and antiquotation "value" are now hardcoded against nbe and
wenzelm@57452
   697
ML.  Minor INCOMPATIBILITY.
wenzelm@57452
   698
wenzelm@57504
   699
* Renamed command 'enriched_type' to 'functor'. INCOMPATIBILITY.
wenzelm@57504
   700
wenzelm@57504
   701
* The symbol "\<newline>" may be used within char or string literals
wenzelm@57504
   702
to represent (Char Nibble0 NibbleA), i.e. ASCII newline.
wenzelm@57504
   703
wenzelm@57504
   704
* Qualified String.implode and String.explode.  INCOMPATIBILITY.
haftmann@56923
   705
wenzelm@57452
   706
* Simplifier: Enhanced solver of preconditions of rewrite rules can
wenzelm@57452
   707
now deal with conjunctions.  For help with converting proofs, the old
wenzelm@57452
   708
behaviour of the simplifier can be restored like this: declare/using
wenzelm@57452
   709
[[simp_legacy_precond]].  This configuration option will disappear
wenzelm@57452
   710
again in the future.  INCOMPATIBILITY.
nipkow@56073
   711
wenzelm@55139
   712
* Simproc "finite_Collect" is no longer enabled by default, due to
wenzelm@55139
   713
spurious crashes and other surprises.  Potential INCOMPATIBILITY.
wenzelm@55139
   714
wenzelm@57452
   715
* Moved new (co)datatype package and its dependencies from session
wenzelm@57452

  "HOL-BNF" to "HOL".  The commands 'bnf', 'wrap_free_constructors',
wenzelm@57452

* New (co)datatype package:
wenzelm@57452
   758
  - Command 'primcorec' is fully implemented.
wenzelm@57452
   759
  - Command 'datatype_new' generates size functions ("size_xxx" and
wenzelm@57452
   760
    "size") as required by 'fun'.
wenzelm@57452
   761
  - BNFs are integrated with the Lifting tool and new-style
wenzelm@57452
   762
    (co)datatypes with Transfer.
wenzelm@57452
   763

   784
  - The generated theorems "xxx.cases" and "xxx.recs" have been
wenzelm@57452
   785
    renamed "xxx.case" and "xxx.rec" (e.g., "sum.cases" ->
wenzelm@57452
   786
    "sum.case").  INCOMPATIBILITY.
wenzelm@57452
   787
  - The generated constants "xxx_case", "xxx_rec", and "xxx_size" have
wenzelm@57452
   788
    been renamed "case_xxx", "rec_xxx", and "size_xxx" (e.g.,

* New internal SAT solver "cdclite" that produces models and proof
wenzelm@57508
   865
traces.  This solver replaces the internal SAT solvers "enumerate" and
wenzelm@57508
   866
"dpll".  Applications that explicitly used one of these two SAT
wenzelm@57508
   867
solvers should use "cdclite" instead. In addition, "cdclite" is now
wenzelm@57508
   868
the default SAT solver for the "sat" and "satx" proof methods and
wenzelm@57508
   869
corresponding tactics; the old default can be restored using "declare
wenzelm@57508

[[sat_solver = zchaff_with_proofs]]".  Minor INCOMPATIBILITY.
wenzelm@57508

wenzelm@57508

* SMT module: A new version of the SMT module, temporarily called
wenzelm@57508
   873
"SMT2", uses SMT-LIB 2 and supports recent versions of Z3 (e.g.,
wenzelm@57508
   874
4.3). The new proof method is called "smt2". CVC3 and CVC4 are also
wenzelm@57508
   875
supported as oracles. Yices is no longer supported, because no version
wenzelm@57508
   876
of the solver can handle both SMT-LIB 2 and quantifiers.
wenzelm@57508
   877
wenzelm@57508
   878
* Activation of Z3 now works via "z3_non_commercial" system option
wenzelm@57508

  - Z3 can now produce Isar proofs.
wenzelm@57508
   885
  - MaSh overhaul:
blanchet@57532
   886
    . New SML-based learning algorithms eliminate the dependency on
wenzelm@57508
   887
      Python and increase performance and reliability.
wenzelm@57508
   888
    . MaSh and MeSh are now used by default together with the
wenzelm@57508
   889
      traditional MePo (Meng-Paulson) relevance filter. To disable
wenzelm@57508
   890
      MaSh, set the "MaSh" system option in Isabelle/jEdit Plugin
wenzelm@57508
   891
      Options / Isabelle / General to "none".

   901
wenzelm@57508
   902
* Nitpick:
wenzelm@57508
   903
  - Fixed soundness bug whereby mutually recursive datatypes could
wenzelm@57508
   904
    take infinite values.
wenzelm@57508
   905
  - Fixed soundness bug with low-level number functions such as
wenzelm@57508
   906
    "Abs_Integ" and "Rep_Integ".
wenzelm@57508
   907
  - Removed "std" option.
wenzelm@57508
   908
  - Renamed "show_datatypes" to "show_types" and "hide_datatypes" to
wenzelm@57508
   909
    "hide_types".
wenzelm@57508
   910
wenzelm@57508

(full_types)' instead. INCOMPATIBILITY.
wenzelm@57508
   913
wenzelm@57508

   915
wenzelm@57508
   916
* Adjustion of INF and SUP operations:
wenzelm@57508
   917
  - Elongated constants INFI and SUPR to INFIMUM and SUPREMUM.
wenzelm@57508
   918
  - Consolidated theorem names containing INFI and SUPR: have INF and
wenzelm@57508
   919
    SUP instead uniformly.
wenzelm@57508
   920
  - More aggressive normalization of expressions involving INF and Inf
wenzelm@57508
   921
    or SUP and Sup.
wenzelm@57508
   922
  - INF_image and SUP_image do not unfold composition.
wenzelm@57508
   923
  - Dropped facts INF_comp, SUP_comp.
wenzelm@57508
   924
  - Default congruence rules strong_INF_cong and strong_SUP_cong, with
wenzelm@57508
   925
    simplifier implication in premises.  Generalize and replace former
wenzelm@57508

* Subtle change of semantics of Thm.eq_thm: theory stamps are not
wenzelm@57504
  1470
compared (according to Thm.thm_ord), but assumed to be covered by the
wenzelm@57504

current background theory.  Thus equivalent data produced in different
wenzelm@57504

branches of the theory graph usually coincides (e.g. relevant for
wenzelm@57504
  1473
theory merge).  Note that the softer Thm.eq_thm_prop is often more

wenzelm@57504
  1482
variables that are meant to become schematic need to be given as
wenzelm@57504

fixed, and are generalized by the explicit context of local variables.

  1484
This corresponds to Isar attributes "where" and "of" with 'for'

wenzelm@56135
  1515
Path.explode, but with compile-time check against the file-system and
wenzelm@56135
  1516
some PIDE markup.  Note that unlike theory source, ML does not have a
wenzelm@56135
  1517
well-defined master directory, so an absolute symbolic path
wenzelm@56135

  1540
* Former "isabelle tty" has been superseded by "isabelle console",
wenzelm@57439
  1541
with implicit build like "isabelle jedit", and without the mostly
wenzelm@57439
  1542
obsolete Isar TTY loop.
wenzelm@57439
  1543
wenzelm@57452
  1544
* Simplified "isabelle display" tool.  Settings variables DVI_VIEWER
wenzelm@57452
  1545
and PDF_VIEWER now refer to the actual programs, not shell
wenzelm@57452
  1546
command-lines.  Discontinued option -c: invocation may be asynchronous
wenzelm@57452
  1547
via desktop environment, without any special precautions.  Potential
wenzelm@57452
  1548
INCOMPATIBILITY with ambitious private settings.
wenzelm@57452
  1549
wenzelm@57413
  1550
* Removed obsolete "isabelle unsymbolize".  Note that the usual format
wenzelm@57413
  1551
for email communication is the Unicode rendering of Isabelle symbols,
wenzelm@57413
  1552
as produced by Isabelle/jEdit, for example.
wenzelm@57413
  1553
wenzelm@57452
  1554
* Removed obsolete tool "wwwfind". Similar functionality may be
wenzelm@57452
  1555
integrated into Isabelle/jEdit eventually.
wenzelm@57452
  1556
wenzelm@57452
  1557
* Improved 'display_drafts' concerning desktop integration and
wenzelm@57452
  1558
repeated invocation in PIDE front-end: re-use single file
wenzelm@57452
  1559
$ISABELLE_HOME_USER/tmp/drafts.pdf and corresponding views.
wenzelm@57084
  1560
wenzelm@57452
  1561
* Session ROOT specifications require explicit 'document_files' for
wenzelm@57452
  1562
robust dependencies on LaTeX sources.  Only these explicitly given
wenzelm@57452
  1563
files are copied to the document output directory, before document
wenzelm@57452
  1564
processing is started.
wenzelm@57452
  1565
wenzelm@57504
  1566
* Windows: support for regular TeX installation (e.g. MiKTeX) instead
wenzelm@57504
  1567
of TeX Live from Cygwin.

  1574
*** Prover IDE -- Isabelle/Scala/jEdit ***
wenzelm@54639
  1575
wenzelm@54639
  1576
* More robust editing of running commands with internal forks,
wenzelm@54639
  1577
e.g. non-terminating 'by' steps.
wenzelm@54639
  1578
wenzelm@54641
  1579
* More relaxed Sledgehammer panel: avoid repeated application of query
wenzelm@54641
  1580
after edits surrounding the command location.
wenzelm@54641
  1581
wenzelm@54648
  1582
* More status information about commands that are interrupted
wenzelm@54648
  1583
accidentally (via physical event or Poly/ML runtime system signal,
wenzelm@54648
  1584
e.g. out-of-memory).

*** System ***
wenzelm@54653
  1588
wenzelm@54653
  1589
* More robust termination of external processes managed by
wenzelm@54664
  1590
Isabelle/ML: support cancellation of tasks within the range of
wenzelm@54664
  1591
milliseconds, as required for PIDE document editing with automatically
wenzelm@54664
  1592
tried tools (e.g. Sledgehammer).
wenzelm@54653
  1593
wenzelm@54648
  1594
* Reactivated Isabelle/Scala kill command for external processes on
wenzelm@54648
  1595
Mac OS X, which was accidentally broken in Isabelle2013-1 due to a
wenzelm@54648
  1596
workaround for some Debian/Ubuntu Linux versions from 2013.

wenzelm@51293
  1603
*** General ***
wenzelm@51293
  1604
wenzelm@53971
  1605
* Discontinued obsolete 'uses' within theory header.  Note that
wenzelm@53971
  1606
commands like 'ML_file' work without separate declaration of file
wenzelm@53971
  1607
dependencies.  Minor INCOMPATIBILITY.
wenzelm@53971
  1608
wenzelm@53971
  1609
* Discontinued redundant 'use' command, which was superseded by
wenzelm@53971
  1610
'ML_file' in Isabelle2013.  Minor INCOMPATIBILITY.
wenzelm@53971
  1611
wenzelm@53016
  1612
* Simplified subscripts within identifiers, using plain \<^sub>
wenzelm@53016
  1613
instead of the second copy \<^isub> and \<^isup>.  Superscripts are
wenzelm@53016
  1614
only for literal tokens within notation; explicit mixfix annotations
wenzelm@53016
  1615
for consts or fixed variables may be used as fall-back for unusual
wenzelm@53016
  1616
names.  Obsolete \<twosuperior> has been expanded to \<^sup>2 in
wenzelm@53016
  1617
Isabelle/HOL.  INCOMPATIBILITY, use "isabelle update_sub_sup" to
wenzelm@53016
  1618
standardize symbols as a starting point for further manual cleanup.
wenzelm@53016
  1619
The ML reference variable "legacy_isub_isup" may be set as temporary
wenzelm@53016
  1620
workaround, to make the prover accept a subset of the old identifier
wenzelm@53016
  1621
syntax.
wenzelm@53016
  1622
wenzelm@53021
  1623
* Document antiquotations: term style "isub" has been renamed to
wenzelm@53021
  1624
"sub".  Minor INCOMPATIBILITY.
wenzelm@53021
  1625
wenzelm@52487
  1626
* Uniform management of "quick_and_dirty" as system option (see also
wenzelm@52487
  1627
"isabelle options"), configuration option within the context (see also
wenzelm@52487
  1628
Config.get in Isabelle/ML), and attribute in Isabelle/Isar.  Minor
wenzelm@52487
  1629
INCOMPATIBILITY, need to use more official Isabelle means to access
wenzelm@52487
  1630
quick_and_dirty, instead of historical poking into mutable reference.
wenzelm@52059
  1631
wenzelm@52060
  1632
* Renamed command 'print_configs' to 'print_options'.  Minor
wenzelm@52060
  1633
INCOMPATIBILITY.
wenzelm@52060
  1634
wenzelm@52430
  1635
* Proper diagnostic command 'print_state'.  Old 'pr' (with its
wenzelm@52430
  1636
implicit change of some global references) is retained for now as
wenzelm@52430
  1637
control command, e.g. for ProofGeneral 3.7.x.
wenzelm@52430
  1638
wenzelm@52549
  1639
* Discontinued 'print_drafts' command with its old-fashioned PS output
wenzelm@52549
  1640
and Unix command-line print spooling.  Minor INCOMPATIBILITY: use
wenzelm@52549
  1641
'display_drafts' instead and print via the regular document viewer.
wenzelm@52549
  1642
wenzelm@53971
  1643
* Updated and extended "isar-ref" and "implementation" manual,
wenzelm@53971
  1644
eliminated old "ref" manual.

  1647
*** Prover IDE -- Isabelle/Scala/jEdit ***
wenzelm@51533
  1648
wenzelm@53971
  1649
* New manual "jedit" for Isabelle/jEdit, see isabelle doc or
wenzelm@53852
  1650
Documentation panel.
wenzelm@53852
  1651
wenzelm@53971
  1652
* Dockable window "Documentation" provides access to Isabelle
wenzelm@53971
  1653
documentation.
wenzelm@52646
  1654
wenzelm@52949
  1655
* Dockable window "Find" provides query operations for formal entities
wenzelm@52949
  1656
(GUI front-end to 'find_theorems' command).
wenzelm@52949
  1657
wenzelm@53050
  1658
* Dockable window "Sledgehammer" manages asynchronous / parallel
wenzelm@53050
  1659
sledgehammer runs over existing document sources, independently of
wenzelm@53050
  1660
normal editing and checking process.
wenzelm@53050
  1661
wenzelm@51533
  1662
* Dockable window "Timing" provides an overview of relevant command
wenzelm@54332
  1663
timing information, depending on option jedit_timing_threshold.  The
wenzelm@54332
  1664
same timing information is shown in the extended tooltip of the
wenzelm@54332
  1665
command keyword, when hovering the mouse over it while the CONTROL or
wenzelm@54332
  1666
COMMAND modifier is pressed.
wenzelm@51533
  1667
wenzelm@53971
  1668
* Improved dockable window "Theories": Continuous checking of proof
wenzelm@53971
  1669
document (visible and required parts) may be controlled explicitly,
wenzelm@53971
  1670
using check box or shortcut "C+e ENTER".  Individual theory nodes may
wenzelm@53971
  1671
be marked explicitly as required and checked in full, using check box
wenzelm@53971
  1672
or shortcut "C+e SPACE".
wenzelm@53971
  1673
wenzelm@54305
  1674
* Improved completion mechanism, which is now managed by the
wenzelm@54305
  1675
Isabelle/jEdit plugin instead of SideKick.  Refined table of Isabelle
wenzelm@54305
  1676
symbol abbreviations (see $ISABELLE_HOME/etc/symbols).
wenzelm@54305
  1677
wenzelm@54319
  1678
* Standard jEdit keyboard shortcut C+b complete-word is remapped to
wenzelm@54319
  1679
isabelle.complete for explicit completion in Isabelle sources.
wenzelm@54319
  1680
INCOMPATIBILITY wrt. jEdit defaults, may have to invent new shortcuts
wenzelm@54319
  1681
to resolve conflict.
wenzelm@54319
  1682
wenzelm@54305
  1683
* Improved support of various "minor modes" for Isabelle NEWS,
wenzelm@54305
  1684
options, session ROOT etc., with completion and SideKick tree view.
wenzelm@54305
  1685
wenzelm@53971
  1686
* Strictly monotonic document update, without premature cancellation of
wenzelm@53971
  1687
running transactions that are still needed: avoid reset/restart of
wenzelm@53971
  1688
such command executions while editing.
wenzelm@53271
  1689
wenzelm@53971
  1690
* Support for asynchronous print functions, as overlay to existing
wenzelm@53971
  1691
document content.
wenzelm@53971
  1692
wenzelm@53971
  1693
* Support for automatic tools in HOL, which try to prove or disprove
wenzelm@53971
  1694
toplevel theorem statements.
wenzelm@53971
  1695
wenzelm@53971
  1696
* Action isabelle.reset-font-size resets main text area font size
wenzelm@54365
  1697
according to Isabelle/Scala plugin option "jedit_font_reset_size" (see
wenzelm@54365
  1698
also "Plugin Options / Isabelle / General").  It can be bound to some
wenzelm@54365
  1699
keyboard shortcut by the user (e.g. C+0 and/or C+NUMPAD0).
wenzelm@53971
  1700
wenzelm@53971
  1701
* File specifications in jEdit (e.g. file browser) may refer to
wenzelm@54351
  1702
$ISABELLE_HOME and $ISABELLE_HOME_USER on all platforms.  Discontinued
wenzelm@54351
  1703
obsolete $ISABELLE_HOME_WINDOWS variable.
wenzelm@53971
  1704
wenzelm@53971
  1705
* Improved support for Linux look-and-feel "GTK+", see also "Utilities
wenzelm@53971
  1706
/ Global Options / Appearance".
wenzelm@53971
  1707
wenzelm@53971
  1708
* Improved support of native Mac OS X functionality via "MacOSX"
wenzelm@53971
  1709
plugin, which is now enabled by default.

*** Pure ***
wenzelm@51313
  1713
ballarin@54049
  1714
* Commands 'interpretation' and 'sublocale' are now target-sensitive.
ballarin@54049
  1715
In particular, 'interpretation' allows for non-persistent
ballarin@54049
  1716
interpretation within "context ... begin ... end" blocks offering a
ballarin@54049
  1717
light-weight alternative to 'sublocale'.  See "isar-ref" manual for
ballarin@54049
  1718
details.
haftmann@51747
  1719
ballarin@51565
  1720
* Improved locales diagnostic command 'print_dependencies'.
ballarin@51565
  1721
wenzelm@51313
  1722
* Discontinued obsolete 'axioms' command, which has been marked as
wenzelm@51313
  1723
legacy since Isabelle2009-2.  INCOMPATIBILITY, use 'axiomatization'
wenzelm@51313
  1724
instead, while observing its uniform scope for polymorphism.
wenzelm@51313
  1725
wenzelm@51316
  1726
* Discontinued empty name bindings in 'axiomatization'.
wenzelm@51316
  1727
INCOMPATIBILITY.
wenzelm@51316
  1728
wenzelm@53971
  1729
* System option "proofs" has been discontinued.  Instead the global
wenzelm@53971
  1730
state of Proofterm.proofs is persistently compiled into logic images
wenzelm@53971
  1731
as required, notably HOL-Proofs.  Users no longer need to change
wenzelm@53971
  1732
Proofterm.proofs dynamically.  Minor INCOMPATIBILITY.
wenzelm@53971
  1733
wenzelm@53971
  1734
* Syntax translation functions (print_translation etc.) always depend
wenzelm@53971
  1735
on Proof.context.  Discontinued former "(advanced)" option -- this is
wenzelm@53971
  1736
now the default.  Minor INCOMPATIBILITY.
wenzelm@53971
  1737
wenzelm@53971
  1738
* Former global reference trace_unify_fail is now available as
wenzelm@53971
  1739
configuration option "unify_trace_failure" (global context only).
wenzelm@53971
  1740
wenzelm@52463
  1741
* SELECT_GOAL now retains the syntactic context of the overall goal
wenzelm@52463
  1742
state (schematic variables etc.).  Potential INCOMPATIBILITY in rare
wenzelm@52463
  1743
situations.

* Stronger precedence of syntax for big intersection and union on
wenzelm@54032
  1749
sets, in accordance with corresponding lattice operations.
wenzelm@54032
  1750
INCOMPATIBILITY.
wenzelm@54032
  1751
wenzelm@54032
  1752
* Notation "{p:A. P}" now allows tuple patterns as well.
wenzelm@54032
  1753
wenzelm@54032
  1754
* Nested case expressions are now translated in a separate check phase
wenzelm@54032
  1755
rather than during parsing. The data for case combinators is separated
wenzelm@54032
  1756
from the datatype package. The declaration attribute
wenzelm@54032
  1757
"case_translation" can be used to register new case combinators:
wenzelm@54032
  1758
wenzelm@54032
  1759
  declare [[case_translation case_combinator constructor1 ... constructorN]]
haftmann@52637
  1760
haftmann@52435
  1761
* Code generator:
wenzelm@53160
  1762
  - 'code_printing' unifies 'code_const' / 'code_type' / 'code_class' /
wenzelm@53160
  1763
    'code_instance'.
wenzelm@53160
  1764
  - 'code_identifier' declares name hints for arbitrary identifiers in
wenzelm@53160
  1765
    generated code, subsuming 'code_modulename'.
wenzelm@53983
  1766
wenzelm@53983
  1767
See the isar-ref manual for syntax diagrams, and the HOL theories for
wenzelm@53983
  1768
examples.
haftmann@52435
  1769
wenzelm@54032
  1770
* Attibute 'code': 'code' now declares concrete and abstract code
wenzelm@54032
  1771
equations uniformly.  Use explicit 'code equation' and 'code abstract'
wenzelm@54032
  1772
to distinguish both when desired.
wenzelm@54032
  1773
wenzelm@54032
  1774
* Discontinued theories Code_Integer and Efficient_Nat by a more
wenzelm@54032
  1775
fine-grain stack of theories Code_Target_Int, Code_Binary_Nat,
wenzelm@54032
  1776
Code_Target_Nat and Code_Target_Numeral.  See the tutorial on code
wenzelm@54032
  1777
generation for details.  INCOMPATIBILITY.
wenzelm@54032
  1778
wenzelm@54032
  1779
* Numeric types are mapped by default to target language numerals:
wenzelm@54032
  1780
natural (replaces former code_numeral) and integer (replaces former
wenzelm@54032
  1781
code_int).  Conversions are available as integer_of_natural /
wenzelm@54032
  1782
natural_of_integer / integer_of_nat / nat_of_integer (in HOL) and
wenzelm@54032
  1783
Code_Numeral.integer_of_natural / Code_Numeral.natural_of_integer (in
wenzelm@54032
  1784
ML).  INCOMPATIBILITY.
wenzelm@54032
  1785
wenzelm@54032
  1786
* Function package: For mutually recursive functions f and g, separate
wenzelm@54032
  1787
cases rules f.cases and g.cases are generated instead of unusable
wenzelm@54032
  1788
f_g.cases which exposed internal sum types. Potential INCOMPATIBILITY,
wenzelm@54032
  1789
in the case that the unusable rule was used nevertheless.
wenzelm@54032
  1790
wenzelm@54032
  1791
* Function package: For each function f, new rules f.elims are
wenzelm@54032
  1792
generated, which eliminate equalities of the form "f x = t".
wenzelm@54032
  1793
wenzelm@54032
  1794
* New command 'fun_cases' derives ad-hoc elimination rules for
wenzelm@54032
  1795
function equations as simplified instances of f.elims, analogous to
wenzelm@54032
  1796
inductive_cases.  See ~~/src/HOL/ex/Fundefs.thy for some examples.

* Lifting:
kuncar@54021
  1799
  - parametrized correspondence relations are now supported:
wenzelm@54378
  1800
    + parametricity theorems for the raw term can be specified in
kuncar@54021
  1801
      the command lift_definition, which allow us to generate stronger
kuncar@54021
  1802
      transfer rules
kuncar@54021
  1803
    + setup_lifting generates stronger transfer rules if parametric
kuncar@54021
  1804
      correspondence relation can be generated
kuncar@54021
  1805
    + various new properties of the relator must be specified to support

      parametricity
kuncar@54021
  1807
    + parametricity theorem for the Quotient relation can be specified
kuncar@54021
  1808
  - setup_lifting generates domain rules for the Transfer package
kuncar@54021
  1809
  - stronger reflexivity prover of respectfulness theorems for type
kuncar@54021
  1810
    copies
kuncar@54021
  1811
  - ===> and --> are now local. The symbols can be introduced
kuncar@54021
  1812
    by interpreting the locale lifting_syntax (typically in an
kuncar@54021
  1813
    anonymous context)
wenzelm@54378
  1814
  - Lifting/Transfer relevant parts of Library/Quotient_* are now in
kuncar@54021
  1815
    Main. Potential INCOMPATIBILITY
kuncar@54021

wenzelm@53160
  1831
    "Reification".

* Revised devices for recursive definitions over finite sets:
haftmann@51489
  1837
  - Only one fundamental fold combinator on finite set remains:
haftmann@51489
  1838
    Finite_Set.fold :: ('a => 'b => 'b) => 'b => 'a set => 'b
haftmann@51489
  1839
    This is now identity on infinite sets.
wenzelm@52745
  1840
  - Locales ("mini packages") for fundamental definitions with
haftmann@51489
  1841
    Finite_Set.fold: folding, folding_idem.
haftmann@51489
  1842
  - Locales comm_monoid_set, semilattice_order_set and
haftmann@51489
  1843
    semilattice_neutr_order_set for big operators on sets.
haftmann@51489
  1844
    See theory Big_Operators for canonical examples.
haftmann@51489
  1845
    Note that foundational constants comm_monoid_set.F and
haftmann@51489
  1846
    semilattice_set.F correspond to former combinators fold_image
haftmann@51489
  1847
    and fold1 respectively.  These are now gone.  You may use
haftmann@51490
  1848
    those foundational constants as substitutes, but it is
wenzelm@53983
  1849
    preferable to interpret the above locales accordingly.
haftmann@51489

wenzelm@53160
  1865
complete lattice but does not assume the existence of the top and
wenzelm@53160
  1866
bottom elements.  Allows to generalize some lemmas about reals and
wenzelm@53160
  1867
extended reals.  Removed SupInf and replaced it by the instantiation
wenzelm@53160
  1868
of conditionally_complete_lattice for real. Renamed lemmas about
wenzelm@53160
  1869
conditionally-complete lattice from Sup_... to cSup_... and from
wenzelm@53160
  1870
Inf_...  to cInf_... to avoid hidding of similar complete lattice

more than one element.  INCOMPATIBILITY.
wenzelm@53160
  1876
wenzelm@53983

wenzelm@53983
  1889
 - Introduce type class (lin)order_topology and
wenzelm@53983
  1890
   linear_continuum_topology.  Allows to generalize theorems about
wenzelm@53983
  1891
   limits and order.  Instances are reals and extended reals.
hoelzl@51732
  1892
hoelzl@51732
  1893
 - continuous and continuos_on from Multivariate_Analysis:
wenzelm@53983
  1894
   "continuous" is the continuity of a function at a filter.  "isCont"
wenzelm@53983
  1895
   is now an abbrevitation: "isCont x f == continuous (at _) f".
wenzelm@53983
  1896
wenzelm@53983
  1897
   Generalized continuity lemmas from isCont to continuous on an
wenzelm@53983
  1898
   arbitrary filter.
wenzelm@53983
  1899
wenzelm@53983
  1900
 - compact from Multivariate_Analysis. Use Bolzano's lemma to prove
wenzelm@53983
  1901
   compactness of closed intervals on reals. Continuous functions
wenzelm@53983
  1902
   attain infimum and supremum on compact sets. The inverse of a
wenzelm@53983
  1903
   continuous function is continuous, when the function is continuous
wenzelm@53983
  1904
   on a compact set.
hoelzl@51732
  1905
hoelzl@51732
  1906
 - connected from Multivariate_Analysis. Use it to prove the
hoelzl@51775
  1907
   intermediate value theorem. Show connectedness of intervals on
hoelzl@51775
  1908
   linear_continuum_topology).
hoelzl@51732
  1909
hoelzl@51732
  1910
 - first_countable_topology from Multivariate_Analysis. Is used to
wenzelm@53983
  1911
   show equivalence of properties on the neighbourhood filter of x and
wenzelm@53983
  1912
   on all sequences converging to x.
wenzelm@53983
  1913
wenzelm@53983
  1914
 - FDERIV: Definition of has_derivative moved to Deriv.thy. Moved
wenzelm@53983
  1915
   theorems from Library/FDERIV.thy to Deriv.thy and base the
wenzelm@53983
  1916
   definition of DERIV on FDERIV. Add variants of DERIV and FDERIV
wenzelm@53983
  1917
   which are restricted to sets, i.e. to represent derivatives from
wenzelm@53983
  1918
   left or right.
hoelzl@51732
  1919
hoelzl@51732
  1920
 - Removed the within-filter. It is replaced by the principal filter:
hoelzl@51732
  1921
hoelzl@51732
  1922
     F within X = inf F (principal X)
hoelzl@51732
  1923
hoelzl@51732
  1924
 - Introduce "at x within U" as a single constant, "at x" is now an
hoelzl@51732
  1925
   abbreviation for "at x within UNIV"
hoelzl@51732
  1926
wenzelm@53983
  1927
 - Introduce named theorem collections tendsto_intros,
wenzelm@53983
  1928
   continuous_intros, continuous_on_intros and FDERIV_intros. Theorems
wenzelm@53983
  1929
   in tendsto_intros (or FDERIV_intros) are also available as
wenzelm@53983
  1930
   tendsto_eq_intros (or FDERIV_eq_intros) where the right-hand side
wenzelm@53983
  1931
   is replaced by a congruence rule. This allows to apply them as
wenzelm@53983
  1932
   intro rules and then proving equivalence by the simplifier.
hoelzl@51732
  1933
hoelzl@51732
  1934
 - Restructured theories in HOL-Complex_Main:
hoelzl@51732
  1935
hoelzl@51732
  1936
   + Moved RealDef and RComplete into Real
hoelzl@51732
  1937
hoelzl@51732

     topological spaces, filters, limits and continuity to it
hoelzl@51732
  1940
hoelzl@51732
  1941
   + Renamed RealVector to Real_Vector_Spaces
hoelzl@51732

  1946
   + Moved Ln and Log to Transcendental
hoelzl@51732
  1947
hoelzl@51732
  1948
   + Moved theorems about continuity from Deriv to Topological_Spaces
hoelzl@51732

  2003
~~/src/HOL/Algebra/poly.  Existing theories should be based on
wenzelm@53983

* Isabelle settings variable ISABELLE_BUILD_JAVA_OPTIONS allows to
wenzelm@52053
  2089
specify global resources of the JVM process run by isabelle build.
wenzelm@52053
  2090
wenzelm@52116
  2091
* Toplevel executable $ISABELLE_HOME/bin/isabelle_scala_script allows
wenzelm@52116
  2092
to run Isabelle/Scala source files as standalone programs.
wenzelm@52116
  2093
wenzelm@52439
  2094
* Improved "isabelle keywords" tool (for old-style ProofGeneral
wenzelm@52439
  2095
keyword tables): use Isabelle/Scala operations, which inspect outer
wenzelm@52439
  2096
syntax without requiring to build sessions first.
wenzelm@52439
  2097
wenzelm@53971
  2098
* Sessions may be organized via 'chapter' specifications in the ROOT
wenzelm@53971
  2099
file, which determines a two-level hierarchy of browser info.  The old
wenzelm@53971
  2100
tree-like organization via implicit sub-session relation (with its
wenzelm@53971
  2101
tendency towards erratic fluctuation of URLs) has been discontinued.
wenzelm@53971
  2102
The default chapter is called "Unsorted".  Potential INCOMPATIBILITY
wenzelm@53971

*** General ***
wenzelm@47967
  2111
wenzelm@50126
  2112
* Theorem status about oracles and unfinished/failed future proofs is
wenzelm@50126
  2113
no longer printed by default, since it is incompatible with
wenzelm@50126
  2114
incremental / parallel checking of the persistent document model.  ML
wenzelm@50126
  2115
function Thm.peek_status may be used to inspect a snapshot of the
wenzelm@50126
  2116
ongoing evaluation process.  Note that in batch mode --- notably
wenzelm@50126
  2117
isabelle build --- the system ensures that future proofs of all
wenzelm@50126
  2118
accessible theorems in the theory context are finished (as before).
wenzelm@50126
  2119
wenzelm@49699
  2120
* Configuration option show_markup controls direct inlining of markup
wenzelm@49699
  2121
into the printed representation of formal entities --- notably type
wenzelm@49699
  2122
and sort constraints.  This enables Prover IDE users to retrieve that
wenzelm@49699
  2123
information via tooltips in the output window, for example.
wenzelm@49699
  2124
wenzelm@48890
  2125
* Command 'ML_file' evaluates ML text from a file directly within the
wenzelm@48890
  2126
theory, without any predeclaration via 'uses' in the theory header.
wenzelm@48890
  2127
wenzelm@49243
  2128
* Old command 'use' command and corresponding keyword 'uses' in the
wenzelm@49243
  2129
theory header are legacy features and will be discontinued soon.
wenzelm@49243
  2130
Tools that load their additional source files may imitate the
wenzelm@49243
  2131
'ML_file' implementation, such that the system can take care of
wenzelm@49243
  2132
dependencies properly.
wenzelm@49243
  2133
wenzelm@47967
  2134
* Discontinued obsolete method fastsimp / tactic fast_simp_tac, which
wenzelm@47967
  2135
is called fastforce / fast_force_tac already since Isabelle2011-1.
wenzelm@47967
  2136
wenzelm@50110
  2137
* Updated and extended "isar-ref" and "implementation" manual, reduced
wenzelm@50110
  2138
remaining material in old "ref" manual.
wenzelm@48120
  2139
wenzelm@51050
  2140
* Improved support for auxiliary contexts that indicate block structure
wenzelm@51050
  2141
for specifications.  Nesting of "context fixes ... context assumes ..."
wenzelm@49841
  2142
and "class ... context ...".
wenzelm@49841
  2143
wenzelm@50772
  2144
* Attribute "consumes" allows a negative value as well, which is
wenzelm@50778
  2145
interpreted relatively to the total number of premises of the rule in
wenzelm@50772
  2146
the target context.  This form of declaration is stable when exported
wenzelm@50772
  2147
from a nested 'context' with additional assumptions.  It is the
wenzelm@50772
  2148
preferred form for definitional packages, notably cases/rules produced
wenzelm@50772
  2149
in HOL/inductive and HOL/function.
wenzelm@50772
  2150
wenzelm@49869
  2151
* More informative error messages for Isar proof commands involving
wenzelm@49869
  2152
lazy enumerations (method applications etc.).
wenzelm@49869
  2153
wenzelm@50213
  2154
* Refined 'help' command to retrieve outer syntax commands according
wenzelm@50213
  2155
to name patterns (with clickable results).
wenzelm@50213

  2158
*** Prover IDE -- Isabelle/Scala/jEdit ***
wenzelm@49968
  2159
wenzelm@49968
  2160
* Parallel terminal proofs ('by') are enabled by default, likewise
wenzelm@49968
  2161
proofs that are built into packages like 'datatype', 'function'.  This
wenzelm@49968
  2162
allows to "run ahead" checking the theory specifications on the
wenzelm@49968
  2163
surface, while the prover is still crunching on internal
wenzelm@49968
  2164
justifications.  Unfinished / cancelled proofs are restarted as
wenzelm@49968
  2165
required to complete full proof checking eventually.
wenzelm@49968
  2166
wenzelm@49968
  2167
* Improved output panel with tooltips, hyperlinks etc. based on the
wenzelm@49968
  2168
same Rich_Text_Area as regular Isabelle/jEdit buffers.  Activation of
wenzelm@49968
  2169
tooltips leads to some window that supports the same recursively,
wenzelm@49968
  2170
which can lead to stacks of tooltips as the semantic document content
wenzelm@49968
  2171
is explored.  ESCAPE closes the whole stack, individual windows may be
wenzelm@49968
  2172
closed separately, or detached to become independent jEdit dockables.
wenzelm@49968
  2173
wenzelm@50717
  2174
* Improved support for commands that produce graph output: the text
wenzelm@50717
  2175
message contains a clickable area to open a new instance of the graph
wenzelm@50717
  2176
browser on demand.
wenzelm@50717
  2177
wenzelm@49968
  2178
* More robust incremental parsing of outer syntax (partial comments,
wenzelm@49968
  2179
malformed symbols).  Changing the balance of open/close quotes and
wenzelm@49968
  2180
comment delimiters works more conveniently with unfinished situations
wenzelm@49968
  2181
that frequently occur in user interaction.
wenzelm@49968
  2182
wenzelm@49968
  2183
* More efficient painting and improved reactivity when editing large
wenzelm@49968
  2184
files.  More scalable management of formal document content.
wenzelm@49968
  2185
wenzelm@50505
  2186
* Smarter handling of tracing messages: prover process pauses after
wenzelm@50505
  2187
certain number of messages per command transaction, with some user
wenzelm@50505
  2188
dialog to stop or continue.  This avoids swamping the front-end with
wenzelm@50119
  2189
potentially infinite message streams.
wenzelm@49968
  2190
wenzelm@49968
  2191
* More plugin options and preferences, based on Isabelle/Scala.  The
wenzelm@49968
  2192
jEdit plugin option panel provides access to some Isabelle/Scala
wenzelm@49968
  2193
options, including tuning parameters for editor reactivity and color
wenzelm@49968
  2194
schemes.
wenzelm@49968
  2195
wenzelm@50184
  2196
* Dockable window "Symbols" provides some editing support for Isabelle
wenzelm@50184
  2197
symbols.
wenzelm@50184
  2198
wenzelm@51082
  2199
* Dockable window "Monitor" shows ML runtime statistics.  Note that
wenzelm@51082
  2200
continuous display of the chart slows down the system.
wenzelm@50701
  2201
wenzelm@50183
  2202
* Improved editing support for control styles: subscript, superscript,
wenzelm@50183
  2203
bold, reset of style -- operating on single symbols or text
wenzelm@50198
  2204
selections.  Cf. keyboard shortcuts C+e DOWN/UP/RIGHT/LEFT.
wenzelm@50198
  2205
wenzelm@50198
  2206
* Actions isabelle.increase-font-size and isabelle.decrease-font-size
wenzelm@50198
  2207
adjust the main text area font size, and its derivatives for output,
wenzelm@50836
  2208
tooltips etc.  Cf. keyboard shortcuts C-PLUS and C-MINUS, which often
wenzelm@50836
  2209
need to be adapted to local keyboard layouts.
wenzelm@50183
  2210
wenzelm@50730
  2211
* More reactive completion popup by default: use \t (TAB) instead of
wenzelm@50730
  2212
\n (NEWLINE) to minimize intrusion into regular flow of editing.  See
wenzelm@50730
  2213
also "Plugin Options / SideKick / General / Code Completion Options".
wenzelm@50730
  2214
wenzelm@50406
  2215
* Implicit check and build dialog of the specified logic session
wenzelm@50406
  2216
image.  For example, HOL, HOLCF, HOL-Nominal can be produced on
wenzelm@50406
  2217
demand, without bundling big platform-dependent heap images in the
wenzelm@50406
  2218
Isabelle distribution.
wenzelm@50406
  2219
wenzelm@49968
  2220
* Uniform Java 7 platform on Linux, Mac OS X, Windows: recent updates
wenzelm@49968
  2221
from Oracle provide better multi-platform experience.  This version is
wenzelm@49968
  2222
now bundled exclusively with Isabelle.

* Code generation for Haskell: restrict unqualified imports from
haftmann@48431
  2228
Haskell Prelude to a small set of fundamental operations.
haftmann@48431
  2229
wenzelm@50646
  2230
* Command 'export_code': relative file names are interpreted
wenzelm@50646
  2231
relatively to master directory of current theory rather than the
wenzelm@50646
  2232
rather arbitrary current working directory.  INCOMPATIBILITY.
haftmann@48371
  2233
wenzelm@48205
  2234
* Discontinued obsolete attribute "COMP".  Potential INCOMPATIBILITY,
wenzelm@48205
  2235
use regular rule composition via "OF" / "THEN", or explicit proof
wenzelm@48205
  2236
structure instead.  Note that Isabelle/ML provides a variety of
wenzelm@48205
  2237
operators like COMP, INCR_COMP, COMP_INCR, which need to be applied
wenzelm@48205
  2238
with some care where this is really required.
wenzelm@48205
  2239
wenzelm@48792
  2240
* Command 'typ' supports an additional variant with explicit sort
wenzelm@48792
  2241
constraint, to infer and check the most general type conforming to a
wenzelm@51063
  2242
given sort.  Example (in HOL):
wenzelm@48792
  2243
wenzelm@48792
  2244
  typ "_ * _ * bool * unit" :: finite
wenzelm@48792
  2245
wenzelm@50716
  2246
* Command 'locale_deps' visualizes all locales and their relations as
wenzelm@50716
  2247
a Hasse diagram.

  2252
* Sledgehammer:
wenzelm@50646
  2253
wenzelm@50646
  2254
  - Added MaSh relevance filter based on machine-learning; see the
wenzelm@50646
  2255
    Sledgehammer manual for details.
wenzelm@50646
  2256
  - Polished Isar proofs generated with "isar_proofs" option.
wenzelm@50646
  2257
  - Rationalized type encodings ("type_enc" option).
blanchet@50720
  2258
  - Renamed "kill_provers" subcommand to "kill_all".
wenzelm@50646
  2259
  - Renamed options:
wenzelm@50646
  2260
      isar_proof ~> isar_proofs
wenzelm@50646
  2261
      isar_shrink_factor ~> isar_shrink

      relevance_thresholds ~> fact_thresholds
wenzelm@50646
  2264
wenzelm@50646
  2265
* Quickcheck: added an optimisation for equality premises.  It is
wenzelm@50646
  2266
switched on by default, and can be switched off by setting the
wenzelm@50646
  2267
configuration quickcheck_optimise_equality to false.

* Lifting:
kuncar@50878
  2273
  - generation of an abstraction function equation in lift_definition
kuncar@50878
  2274
  - quot_del attribute
kuncar@50878
  2275
  - renamed no_abs_code -> no_code (INCOMPATIBILITY.)
kuncar@50878
  2276
wenzelm@50646
  2277
* Simproc "finite_Collect" rewrites set comprehensions into pointfree
wenzelm@50646
  2278
expressions.
wenzelm@50646
  2279
wenzelm@50646
  2280
* Preprocessing of the code generator rewrites set comprehensions into
wenzelm@50646
  2281
pointfree expressions.
wenzelm@50646
  2282
wenzelm@50646
  2283
* The SMT solver Z3 has now by default a restricted set of directly
wenzelm@50646
  2284
supported features. For the full set of features (div/mod, nonlinear
wenzelm@50646
  2285
arithmetic, datatypes/records) with potential proof reconstruction
wenzelm@50646
  2286
failures, enable the configuration option "z3_with_extensions".  Minor
wenzelm@50646
  2287
INCOMPATIBILITY.
haftmann@49948
  2288
wenzelm@49836
  2289
* Simplified 'typedef' specifications: historical options for implicit
wenzelm@49836
  2290
set definition and alternative name have been discontinued.  The
wenzelm@49836
  2291
former behavior of "typedef (open) t = A" is now the default, but
wenzelm@49836
  2292
written just "typedef t = A".  INCOMPATIBILITY, need to adapt theories
wenzelm@49836
  2293
accordingly.
wenzelm@49836
  2294
wenzelm@50646
  2295
* Removed constant "chars"; prefer "Enum.enum" on type "char"
wenzelm@50646
  2296
directly.  INCOMPATIBILITY.
wenzelm@50646
  2297
wenzelm@50646
  2298
* Moved operation product, sublists and n_lists from theory Enum to
wenzelm@50646
  2299
List.  INCOMPATIBILITY.
haftmann@49822
  2300
haftmann@49739
  2301
* Theorem UN_o generalized to SUP_comp.  INCOMPATIBILITY.
haftmann@49739
  2302
haftmann@49738
  2303
* Class "comm_monoid_diff" formalises properties of bounded
haftmann@49388
  2304
subtraction, with natural numbers and multisets as typical instances.
haftmann@49388
  2305
wenzelm@50646
  2306
* Added combinator "Option.these" with type "'a option set => 'a set".
wenzelm@50646
  2307
wenzelm@50646
  2308
* Theory "Transitive_Closure": renamed lemmas
wenzelm@50646
  2309
wenzelm@50646
  2310
  reflcl_tranclp -> reflclp_tranclp
wenzelm@50646

INCOMPATIBILITY.
wenzelm@50646
  2314
wenzelm@50646
  2315
* Theory "Rings": renamed lemmas (in class semiring)
wenzelm@50646
  2316
wenzelm@50646
  2317
  left_distrib ~> distrib_right
wenzelm@50646
  2318
  right_distrib ~> distrib_left
wenzelm@50646
  2319
wenzelm@50646
  2320
INCOMPATIBILITY.
wenzelm@50646
  2321
wenzelm@50646
  2322
* Generalized the definition of limits:
wenzelm@50646
  2323
wenzelm@50646
  2324
  - Introduced the predicate filterlim (LIM x F. f x :> G) which
wenzelm@50646
  2325
    expresses that when the input values x converge to F then the
wenzelm@50646
  2326
    output f x converges to G.
wenzelm@50646
  2327
wenzelm@50646
  2328
  - Added filters for convergence to positive (at_top) and negative
wenzelm@50646
  2329
    infinity (at_bot).
wenzelm@50646
  2330
wenzelm@50646
  2331
  - Moved infinity in the norm (at_infinity) from
wenzelm@50646
  2332
    Multivariate_Analysis to Complex_Main.
wenzelm@50646
  2333
wenzelm@50646
  2334
  - Removed real_tendsto_inf, it is superseded by "LIM x F. f x :>
wenzelm@50646
  2335
    at_top".
wenzelm@50646
  2336
wenzelm@50646
  2337
INCOMPATIBILITY.
wenzelm@50646
  2338
wenzelm@50646
  2339
* Theory "Library/Option_ord" provides instantiation of option type to
wenzelm@50646
  2340
lattice type classes.
wenzelm@50646
  2341
wenzelm@50646
  2342
* Theory "Library/Multiset": renamed
wenzelm@50646
  2343
wenzelm@50646
  2344
    constant fold_mset ~> Multiset.fold
wenzelm@50646
  2345
    fact fold_mset_commute ~> fold_mset_comm
wenzelm@50646
  2346
wenzelm@50646
  2347
INCOMPATIBILITY.
wenzelm@50646
  2348
wenzelm@50646
  2349
* Renamed theory Library/List_Prefix to Library/Sublist, with related
wenzelm@50646
  2350
changes as follows.
wenzelm@50646
  2351
wenzelm@50646
  2352
  - Renamed constants (and related lemmas)
Christian@49145
  2353
Christian@49145
  2354
      prefix ~> prefixeq
Christian@49145
  2355
      strict_prefix ~> prefix
Christian@49145
  2356
wenzelm@50646
  2357
  - Replaced constant "postfix" by "suffixeq" with swapped argument
wenzelm@50646
  2358
    order (i.e., "postfix xs ys" is now "suffixeq ys xs") and dropped
wenzelm@50646
  2359
    old infix syntax "xs >>= ys"; use "suffixeq ys xs" instead.
wenzelm@50646
  2360
    Renamed lemmas accordingly.
wenzelm@50646
  2361
wenzelm@50646
  2362
  - Added constant "list_hembeq" for homeomorphic embedding on
wenzelm@50646
  2363
    lists. Added abbreviation "sublisteq" for special case
wenzelm@50646
  2364
    "list_hembeq (op =)".
wenzelm@50646
  2365
wenzelm@50646
  2366
  - Theory Library/Sublist no longer provides "order" and "bot" type
wenzelm@50646
  2367
    class instances for the prefix order (merely corresponding locale
wenzelm@50646
  2368
    interpretations). The type class instances are now in theory
wenzelm@50646

wenzelm@50646
  2398
* Theory Library/FuncSet: Extended support for Pi and extensional and
wenzelm@50646
  2399
introduce the extensional dependent function space "PiE". Replaced
wenzelm@50646
  2400
extensional_funcset by an abbreviation, and renamed lemmas from

wenzelm@50646
  2420
* Theory Library/Phantom: generic phantom type to make a type
wenzelm@50646
  2421
parameter appear in a constant's type.  This alternative to adding
wenzelm@50646
  2422
TYPE('a) as another parameter avoids unnecessary closures in generated

  2423
code.
wenzelm@50646

wenzelm@50646
  2469
  - Added simproc "measurable" to automatically prove measurability.
wenzelm@50646
  2470
wenzelm@50646
  2471
  - Added induction rules for sigma sets with disjoint union
wenzelm@50646
  2472
    (sigma_sets_induct_disjoint) and for Borel-measurable functions
wenzelm@50646
  2473
    (borel_measurable_induct).
wenzelm@50646
  2474
wenzelm@50646
  2475

with support for mixed, nested recursion and interesting non-free
wenzelm@50646
  2483

blanchet@48094
  2484
wenzelm@50991
  2485

*** Document preparation ***
wenzelm@48206
  2500
wenzelm@50646
  2501
* Dropped legacy antiquotations "term_style" and "thm_style", since
wenzelm@50646
  2502
styles may be given as arguments to "term" and "thm" already.
wenzelm@50646
  2503
Discontinued legacy styles "prem1" .. "prem19".
wenzelm@50646
  2504
wenzelm@50646
  2505
* Default LaTeX rendering for \<euro> is now based on eurosym package,
wenzelm@50646
  2506
instead of slightly exotic babel/greek.
wenzelm@48206
  2507
wenzelm@48616
  2508
* Document variant NAME may use different LaTeX entry point
wenzelm@48616
  2509
document/root_NAME.tex if that file exists, instead of the common
wenzelm@48616
  2510
document/root.tex.
wenzelm@48616
  2511
wenzelm@48657
  2512
* Simplified custom document/build script, instead of old-style

*** ML ***
wenzelm@48992
  2517
wenzelm@50646
  2518
* The default limit for maximum number of worker threads is now 8,
wenzelm@50646
  2519
instead of 4, in correspondence to capabilities of contemporary
wenzelm@50646
  2520
hardware and Poly/ML runtime system.
wenzelm@50646
  2521
wenzelm@49869
  2522
* Type Seq.results and related operations support embedded error
wenzelm@49869
  2523
messages within lazy enumerations, and thus allow to provide
wenzelm@49869
  2524
informative errors in the absence of any usable results.
wenzelm@49869
  2525
wenzelm@48992
  2526
* Renamed Position.str_of to Position.here to emphasize that this is a
wenzelm@48992
  2527
formal device to inline positions into message text, but not
wenzelm@48992
  2528
necessarily printing visible text.

*** System ***
wenzelm@48206
  2532
wenzelm@48585
  2533
* Advanced support for Isabelle sessions and build management, see
wenzelm@48585
  2534
"system" manual for the chapter of that name, especially the "isabelle
wenzelm@51056
  2535
build" tool and its examples.  The "isabelle mkroot" tool prepares
wenzelm@51056
  2536
session root directories for use with "isabelle build", similar to
wenzelm@51056
  2537
former "isabelle mkdir" for "isabelle usedir".  Note that this affects
wenzelm@51056
  2538
document preparation as well.  INCOMPATIBILITY, isabelle usedir /
wenzelm@48736
  2539
mkdir / make are rendered obsolete.
wenzelm@48736
  2540
wenzelm@51056
  2541
* Discontinued obsolete Isabelle/build script, it is superseded by the
wenzelm@51056
  2542
regular isabelle build tool.  For example:
wenzelm@51056
  2543
wenzelm@51056
  2544
  isabelle build -s -b HOL
wenzelm@51056
  2545
wenzelm@48736
  2546
* Discontinued obsolete "isabelle makeall".
wenzelm@48585
  2547
wenzelm@48722
  2548
* Discontinued obsolete IsaMakefile and ROOT.ML files from the
wenzelm@48722
  2549
Isabelle distribution, except for rudimentary src/HOL/IsaMakefile that
wenzelm@48722
  2550
provides some traditional targets that invoke "isabelle build".  Note
wenzelm@48722
  2551
that this is inefficient!  Applications of Isabelle/HOL involving
wenzelm@48722
  2552
"isabelle make" should be upgraded to use "isabelle build" directly.
wenzelm@48722
  2553
wenzelm@48693
  2554
* The "isabelle options" tool prints Isabelle system options, as
wenzelm@48693
  2555
required for "isabelle build", for example.
wenzelm@48693
  2556
wenzelm@50646
  2557
* The "isabelle logo" tool produces EPS and PDF format simultaneously.
wenzelm@50646
  2558
Minor INCOMPATIBILITY in command-line options.
wenzelm@50646
  2559
wenzelm@50646
  2560
* The "isabelle install" tool has now a simpler command-line.  Minor
wenzelm@50646
  2561
INCOMPATIBILITY.
wenzelm@50646
  2562
wenzelm@48844
  2563
* The "isabelle components" tool helps to resolve add-on components
wenzelm@48844
  2564
that are not bundled, or referenced from a bare-bones repository
wenzelm@48844
  2565
version of Isabelle.
wenzelm@48844
  2566
wenzelm@50646
  2567
* Settings variable ISABELLE_PLATFORM_FAMILY refers to the general
wenzelm@50646
  2568
platform family: "linux", "macos", "windows".
wenzelm@50646
  2569
wenzelm@50646
  2570
* The ML system is configured as regular component, and no longer
wenzelm@50646
  2571
picked up from some surrounding directory.  Potential INCOMPATIBILITY
wenzelm@50646
  2572
for home-made settings.
wenzelm@50132
  2573
wenzelm@50701
  2574
* Improved ML runtime statistics (heap, threads, future tasks etc.).
wenzelm@50701
  2575
wenzelm@48206
  2576
* Discontinued support for Poly/ML 5.2.1, which was the last version
wenzelm@48206
  2577
without exception positions and advanced ML compiler/toplevel
wenzelm@48206
  2578
configuration.
wenzelm@48206
  2579
wenzelm@48574
  2580
* Discontinued special treatment of Proof General -- no longer guess
wenzelm@48574
  2581
PROOFGENERAL_HOME based on accidental file-system layout.  Minor
wenzelm@48574
  2582
INCOMPATIBILITY: provide PROOFGENERAL_HOME and PROOFGENERAL_OPTIONS
wenzelm@48574
  2583
settings manually, or use a Proof General version that has been
wenzelm@48574
  2584
bundled as Isabelle component.

wenzelm@45593
  2591
*** General ***
wenzelm@45593
  2592
wenzelm@45614
  2593
* Prover IDE (PIDE) improvements:
wenzelm@45614
  2594
wenzelm@47585
  2595
  - more robust Sledgehammer integration (as before the sledgehammer
wenzelm@47806
  2596
    command-line needs to be typed into the source buffer)
wenzelm@45614
  2597
  - markup for bound variables
wenzelm@47806
  2598
  - markup for types of term variables (displayed as tooltips)
wenzelm@46956
  2599
  - support for user-defined Isar commands within the running session
wenzelm@47158
  2600
  - improved support for Unicode outside original 16bit range
wenzelm@47158
  2601
    e.g. glyph for \<A> (thanks to jEdit 4.5.1)
wenzelm@45614
  2602
wenzelm@47806
  2603
* Forward declaration of outer syntax keywords within the theory
wenzelm@47806
  2604
header -- minor INCOMPATIBILITY for user-defined commands.  Allow new
wenzelm@47806
  2605
commands to be used in the same theory where defined.
wenzelm@46485
  2606
wenzelm@47482
  2607
* Auxiliary contexts indicate block structure for specifications with
wenzelm@47482
  2608
additional parameters and assumptions.  Such unnamed contexts may be
wenzelm@47482
  2609
nested within other targets, like 'theory', 'locale', 'class',
wenzelm@47482
  2610
'instantiation' etc.  Results from the local context are generalized
wenzelm@47482
  2611
accordingly and applied to the enclosing target context.  Example:
wenzelm@47482
  2612
wenzelm@47482
  2613
  context
wenzelm@47482
  2614
    fixes x y z :: 'a
wenzelm@47482
  2615
    assumes xy: "x = y" and yz: "y = z"
wenzelm@47482
  2616
  begin
wenzelm@47482
  2617
wenzelm@47482
  2618
  lemma my_trans: "x = z" using xy yz by simp
wenzelm@47482
  2619
wenzelm@47482
  2620
  end
wenzelm@47482
  2621
wenzelm@47482
  2622
  thm my_trans
wenzelm@47482
  2623
wenzelm@47482
  2624
The most basic application is to factor-out context elements of
wenzelm@47482
  2625
several fixes/assumes/shows theorem statements, e.g. see
wenzelm@47482
  2626
~~/src/HOL/Isar_Examples/Group_Context.thy
wenzelm@47482
  2627
wenzelm@47482
  2628
Any other local theory specification element works within the "context
wenzelm@47482
  2629
... begin ... end" block as well.
wenzelm@47482
  2630
wenzelm@47484
  2631
* Bundled declarations associate attributed fact expressions with a
wenzelm@47484
  2632
given name in the context.  These may be later included in other
wenzelm@47484
  2633
contexts.  This allows to manage context extensions casually, without
wenzelm@47855
  2634
the logical dependencies of locales and locale interpretation.  See
wenzelm@47855
  2635
commands 'bundle', 'include', 'including' etc. in the isar-ref manual.
wenzelm@47484
  2636
wenzelm@47829
  2637
* Commands 'lemmas' and 'theorems' allow local variables using 'for'
wenzelm@47829
  2638
declaration, and results are standardized before being stored.  Thus
wenzelm@47829
  2639
old-style "standard" after instantiation or composition of facts
wenzelm@47829
  2640
becomes obsolete.  Minor INCOMPATIBILITY, due to potential change of
wenzelm@47829
  2641
indices of schematic variables.

* Rule attributes in local theory declarations (e.g. locale or class)
wenzelm@47829
  2644
are now statically evaluated: the resulting theorem is stored instead
wenzelm@47829
  2645
of the original expression.  INCOMPATIBILITY in rare situations, where
wenzelm@47829
  2646
the historic accident of dynamic re-evaluation in interpretations
wenzelm@47829
  2647
etc. was exploited.
wenzelm@47829
  2648
wenzelm@47829
  2649
* New tutorial "Programming and Proving in Isabelle/HOL"
wenzelm@47829
  2650
("prog-prove").  It completely supersedes "A Tutorial Introduction to
wenzelm@47829
  2651
Structured Isar Proofs" ("isar-overview"), which has been removed.  It
wenzelm@47829
  2652
also supersedes "Isabelle/HOL, A Proof Assistant for Higher-Order
wenzelm@47829
  2653
Logic" as the recommended beginners tutorial, but does not cover all
wenzelm@47829
  2654
of the material of that old tutorial.
wenzelm@47829
  2655
wenzelm@47829
  2656
* Updated and extended reference manuals: "isar-ref",
wenzelm@47829
  2657
"implementation", "system"; reduced remaining material in old "ref"
wenzelm@47829
  2658
manual.

  2662
wenzelm@46976
  2663
* Command 'definition' no longer exports the foundational "raw_def"
wenzelm@46976
  2664
into the user context.  Minor INCOMPATIBILITY, may use the regular
wenzelm@46976
  2665
"def" result with attribute "abs_def" to imitate the old version.
wenzelm@46976
  2666
wenzelm@47855
  2667
* Attribute "abs_def" turns an equation of the form "f x y == t" into
wenzelm@47855
  2668
"f == %x y. t", which ensures that "simp" or "unfold" steps always
wenzelm@47855
  2669
expand it.  This also works for object-logic equality.  (Formerly
wenzelm@47855
  2670
undocumented feature.)
wenzelm@47855
  2671
wenzelm@47856
  2672
* Sort constraints are now propagated in simultaneous statements, just
wenzelm@47856
  2673
like type constraints.  INCOMPATIBILITY in rare situations, where
wenzelm@47856
  2674
distinct sorts used to be assigned accidentally.  For example:
wenzelm@47856
  2675
wenzelm@47856
  2676
  lemma "P (x::'a::foo)" and "Q (y::'a::bar)"  -- "now illegal"
wenzelm@47856
  2677
wenzelm@47856
  2678
  lemma "P (x::'a)" and "Q (y::'a::bar)"
wenzelm@47856
  2679
    -- "now uniform 'a::bar instead of default sort for first occurrence (!)"
wenzelm@47856
  2680
wenzelm@47856
  2681
* Rule composition via attribute "OF" (or ML functions OF/MRS) is more
wenzelm@47856
  2682
tolerant against multiple unifiers, as long as the final result is
wenzelm@47856
  2683
unique.  (As before, rules are composed in canonical right-to-left
wenzelm@47856
  2684
order to accommodate newly introduced premises.)
wenzelm@47856
  2685
wenzelm@47806
  2686
* Renamed some inner syntax categories:
wenzelm@47806
  2687
wenzelm@47806
  2688
    num ~> num_token
wenzelm@47806
  2689
    xnum ~> xnum_token
wenzelm@47806
  2690
    xstr ~> str_token
wenzelm@47806
  2691
wenzelm@47806
  2692
Minor INCOMPATIBILITY.  Note that in practice "num_const" or
wenzelm@47806
  2693
"num_position" etc. are mainly used instead (which also include
wenzelm@47806
  2694
position information via constraints).
wenzelm@47806
  2695
wenzelm@47829
  2696
* Simplified configuration options for syntax ambiguity: see
wenzelm@47829
  2697
"syntax_ambiguity_warning" and "syntax_ambiguity_limit" in isar-ref
wenzelm@47829
  2698
manual.  Minor INCOMPATIBILITY.
wenzelm@47829
  2699
wenzelm@47856
  2700
* Discontinued configuration option "syntax_positions": atomic terms
wenzelm@47856
  2701
in parse trees are always annotated by position constraints.
wenzelm@45134
  2702
wenzelm@47464
  2703
* Old code generator for SML and its commands 'code_module',
wenzelm@45383
  2704
'code_library', 'consts_code', 'types_code' have been discontinued.
haftmann@46028
  2705
Use commands of the generic code generator instead.  INCOMPATIBILITY.
wenzelm@45383
  2706
wenzelm@47464
  2707
* Redundant attribute "code_inline" has been discontinued. Use
wenzelm@47464
  2708
"code_unfold" instead.  INCOMPATIBILITY.
wenzelm@47464
  2709
wenzelm@47464
  2710
* Dropped attribute "code_unfold_post" in favor of the its dual
wenzelm@47464
  2711
"code_abbrev", which yields a common pattern in definitions like
haftmann@46028
  2712
haftmann@46028
  2713
  definition [code_abbrev]: "f = t"
haftmann@46028
  2714
haftmann@46028
  2715
INCOMPATIBILITY.
wenzelm@45383
  2716
wenzelm@47856
  2717
* Obsolete 'types' command has been discontinued.  Use 'type_synonym'
wenzelm@47856
  2718
instead.  INCOMPATIBILITY.
wenzelm@47856
  2719
wenzelm@47856
  2720
* Discontinued old "prems" fact, which used to refer to the accidental
wenzelm@47856
  2721
collection of foundational premises in the context (already marked as
wenzelm@47856
  2722
legacy since Isabelle2011).

* Type 'a set is now a proper type constructor (just as before
wenzelm@47464
  2728
Isabelle2008).  Definitions mem_def and Collect_def have disappeared.
wenzelm@47464
  2729
Non-trivial INCOMPATIBILITY.  For developments keeping predicates and
wenzelm@47855
  2730
sets separate, it is often sufficient to rephrase some set S that has
wenzelm@47855
  2731
been accidentally used as predicates by "%x. x : S", and some
wenzelm@47855
  2732
predicate P that has been accidentally used as set by "{x. P x}".
