* Improved scheduling for urgent print tasks (e.g. command state output,
wenzelm@60610
    13
interactive queries) wrt. long-running background tasks.

*** Isar ***
wenzelm@60406
    17
wenzelm@60406
    18
* Command 'obtain' binds term abbreviations (via 'is' patterns) in the
wenzelm@60406
    19
proof body as well, abstracted over relevant parameters.
wenzelm@60406
    20
wenzelm@60477
    21
* Improved type-inference for theorem statement 'obtains': separate
wenzelm@60477
    22
parameter scope for of each clause.
wenzelm@60477
    23
wenzelm@60408
    24
* Term abbreviations via 'is' patterns also work for schematic
wenzelm@60408
    25
statements: result is abstracted over unknowns.
wenzelm@60408
    26
wenzelm@60414
    27
* Local goals ('have', 'show', 'hence', 'thus') allow structured
wenzelm@60414
    28
statements like fixes/assumes/shows in theorem specifications, but the
wenzelm@60555
    29
notation is postfix with keywords 'if' (or 'when') and 'for'. For
wenzelm@60555
    30
example:
wenzelm@60414
    31
wenzelm@60414
    32
  have result: "C x y"
wenzelm@60414
    33
    if "A x" and "B y"
wenzelm@60414
    34
    for x :: 'a and y :: 'a
wenzelm@60414
    35
    <proof>
wenzelm@60414
    36
wenzelm@60449
    37
The local assumptions are bound to the name "that". The result is
wenzelm@60449
    38
exported from context of the statement as usual. The above roughly
wenzelm@60414
    39
corresponds to a raw proof block like this:
wenzelm@60414
    40
wenzelm@60414
    41
  {
wenzelm@60414
    42
    fix x :: 'a and y :: 'a
wenzelm@60449
    43
    assume that: "A x" "B y"
wenzelm@60414
    44
    have "C x y" <proof>
wenzelm@60414
    45
  }
wenzelm@60414
    46
  note result = this
wenzelm@60406
    47
wenzelm@60555
    48
The keyword 'when' may be used instead of 'if', to indicate 'presume'
wenzelm@60555
    49
instead of 'assume' above.
wenzelm@60555
    50
wenzelm@60595
    51
* The meaning of 'show' with Pure rule statements has changed: premises
wenzelm@60595
    52
are treated in the sense of 'assume', instead of 'presume'. This means,
wenzelm@60595
    53
a goal like "\<And>x. A x \<Longrightarrow> B x \<Longrightarrow> C x" can be solved completely as follows:
wenzelm@60595
    54
wenzelm@60595
    55
  show "\<And>x. A x \<Longrightarrow> B x \<Longrightarrow> C x"
wenzelm@60595
    56
wenzelm@60595
    57
or:
wenzelm@60595
    58
wenzelm@60595
    59
  show "C x" if "A x" "B x" for x
wenzelm@60595
    60
wenzelm@60595
    61
Rare INCOMPATIBILITY, the old behaviour may be recovered as follows:
wenzelm@60595
    62
wenzelm@60595
    63
  show "C x" when "A x" "B x" for x
wenzelm@60595
    64
wenzelm@60406
    65
* New command 'supply' supports fact definitions during goal refinement
wenzelm@60406
    66
('apply' scripts).
wenzelm@60406
    67
wenzelm@60459
    68
* New command 'consider' states rules for generalized elimination and
wenzelm@60459
    69
case splitting. This is like a toplevel statement "theorem obtains" used
wenzelm@60459
    70
within a proof body; or like a multi-branch 'obtain' without activation
wenzelm@60459
    71
of the local context elements yet.
wenzelm@60459
    72
wenzelm@60455
    73
* Proof method "cases" allows to specify the rule as first entry of
wenzelm@60455
    74
chained facts.  This is particularly useful with 'consider':
wenzelm@60455
    75
wenzelm@60455
    76
  consider (a) A | (b) B | (c) C <proof>
wenzelm@60455
    77
  then have something
wenzelm@60455
    78
  proof cases
wenzelm@60455
    79
    case a
wenzelm@60455
    80
    then show ?thesis <proof>
wenzelm@60455
    81
  next
wenzelm@60455
    82
    case b
wenzelm@60455
    83
    then show ?thesis <proof>
wenzelm@60455
    84
  next
wenzelm@60455
    85
    case c
wenzelm@60455
    86
    then show ?thesis <proof>
wenzelm@60455
    87
  qed
wenzelm@60455
    88
wenzelm@60565
    89
* Command 'case' allows fact name and attribute specification like this:
wenzelm@60565
    90
wenzelm@60565
    91
  case a: (c xs)
wenzelm@60565
    92
  case a [attributes]: (c xs)
wenzelm@60565
    93
wenzelm@60565
    94
Facts that are introduced by invoking the case context are uniformly
wenzelm@60565
    95
qualified by "a"; the same name is used for the cumulative fact. The old
wenzelm@60565
    96
form "case (c xs) [attributes]" is no longer supported. Rare
wenzelm@60565
    97
INCOMPATIBILITY, need to adapt uses of case facts in exotic situations,
wenzelm@60565
    98
and always put attributes in front.
wenzelm@60565
    99
wenzelm@60618
   100
* The standard proof method of commands 'proof' and '..' is now called
wenzelm@60618
   101
"standard" to make semantically clear what it is; the old name "default"
wenzelm@60618
   102
is still available as legacy for some time. Documentation now explains
wenzelm@60618
   103
'..' more accurately as "by standard" instead of "by rule".
wenzelm@60618
   104
wenzelm@60631
   105
* Command 'subgoal' allows to impose some structure on backward
wenzelm@60631
   106
refinements, to avoid proof scripts degenerating into long of 'apply'
wenzelm@60631
   107
sequences. Further explanations and examples are given in the isar-ref
wenzelm@60631
   108
manual.
wenzelm@60631
   109
wenzelm@60578
   110
* Proof method "goals" turns the current subgoals into cases within the
wenzelm@60578
   111
context; the conclusion is bound to variable ?case in each case.
wenzelm@60617
   112
For example:
wenzelm@60617
   113
wenzelm@60617
   114
lemma "\<And>x. A x \<Longrightarrow> B x \<Longrightarrow> C x"
wenzelm@60622
   115
  and "\<And>y z. U y \<Longrightarrow> V z \<Longrightarrow> W y z"
wenzelm@60622
   116
proof goals
wenzelm@60622
   117
  case (1 x)
wenzelm@60622
   118
  then show ?case using \<open>A x\<close> \<open>B x\<close> sorry
wenzelm@60622
   119
next
wenzelm@60622
   120
  case (2 y z)
wenzelm@60622
   121
  then show ?case using \<open>U y\<close> \<open>V z\<close> sorry
wenzelm@60622
   122
qed
wenzelm@60622
   123
wenzelm@60622
   124
lemma "\<And>x. A x \<Longrightarrow> B x \<Longrightarrow> C x"
wenzelm@60622
   125
  and "\<And>y z. U y \<Longrightarrow> V z \<Longrightarrow> W y z"
wenzelm@60617
   126
proof goals
wenzelm@60617
   127
  case prems: 1
wenzelm@60617
   128
  then show ?case using prems sorry
wenzelm@60617
   129
next
wenzelm@60617
   130
  case prems: 2
wenzelm@60617
   131
  then show ?case using prems sorry
wenzelm@60617
   132
qed
wenzelm@60578
   133
wenzelm@60581
   134
* The undocumented feature of implicit cases goal1, goal2, goal3, etc.
wenzelm@60617
   135
is marked as legacy, and will be removed eventually. The proof method
wenzelm@60617
   136
"goals" achieves a similar effect within regular Isar; often it can be
wenzelm@60617
   137
done more adequately by other means (e.g. 'consider').
wenzelm@60581
   138
wenzelm@60551
   139
* Nesting of Isar goal structure has been clarified: the context after
wenzelm@60551
   140
the initial backwards refinement is retained for the whole proof, within
wenzelm@60551
   141
all its context sections (as indicated via 'next'). This is e.g.
wenzelm@60551
   142
relevant for 'using', 'including', 'supply':
wenzelm@60551
   143
wenzelm@60551
   144
  have "A \<and> A" if a: A for A
wenzelm@60551
   145
    supply [simp] = a
wenzelm@60551
   146
  proof
wenzelm@60551
   147
    show A by simp
wenzelm@60551
   148
  next
wenzelm@60551
   149
    show A by simp
wenzelm@60551
   150
  qed
wenzelm@60551
   151
wenzelm@60554
   152
* Method "sleep" succeeds after a real-time delay (in seconds). This is
wenzelm@60554
   153
occasionally useful for demonstration and testing purposes.
wenzelm@60554

wenzelm@60331
   156
*** Pure ***
wenzelm@60331
   157
wenzelm@60489
   158
* The vacuous fact "TERM x" may be established "by fact" or as `TERM x`
wenzelm@60489
   159
as well, not just "by this" or "." as before.
wenzelm@60489
   160
wenzelm@60331
   161
* Configuration option rule_insts_schematic has been discontinued
wenzelm@60331
   162
(intermediate legacy feature in Isabelle2015).  INCOMPATIBILITY.
wenzelm@60331
   163
haftmann@60347
   164
* Abbreviations in type classes now carry proper sort constraint.
haftmann@60347
   165
Rare INCOMPATIBILITY in situations where the previous misbehaviour
haftmann@60347
   166
has been exploited previously.
haftmann@60347
   167
haftmann@60347
   168
* Refinement of user-space type system in type classes: pseudo-local
haftmann@60347
   169
operations behave more similar to abbreviations.  Potential
haftmann@60347
   170
INCOMPATIBILITY in exotic situations.

nipkow@60171

wenzelm@60841
   175
* Theory Map: lemma map_of_is_SomeD was a clone of map_of_SomeD and has
wenzelm@60841
   176
been removed. INCOMPATIBILITY.
wenzelm@60841
   177
lars@60712
   178
* Quickcheck setup for finite sets.
lars@60712
   179
nipkow@60171
   180
* Discontinued simp_legacy_precond. Potential INCOMPATIBILITY.
wenzelm@60138
   181
blanchet@60306
   182
* Sledgehammer:
blanchet@60306
   183
  - Proof reconstruction has been improved, to minimize the incidence of
blanchet@60306
   184
    cases where Sledgehammer gives a proof that does not work.
blanchet@60306
   185
  - Auto Sledgehammer now minimizes and preplays the results.
blanchet@60584
   186
  - The URL for remote provers on SystemOnTPTP has been updated.
blanchet@60306
   187
blanchet@60310
   188
* Nitpick:
blanchet@60310
   189
  - Removed "check_potential" and "check_genuine" options.
blanchet@60310
   190
haftmann@60868
   191
* Division on integers is bootstrapped directly from division on
haftmann@60868
   192
naturals and uses generic numeral algorithm for computations.
haftmann@60868
   193
Slight INCOMPATIBILITY, simproc numeral_divmod replaces and generalizes
haftmann@60868
   194
former simprocs binary_int_div and binary_int_mod
haftmann@60868
   195
haftmann@60516
   196
* Tightened specification of class semiring_no_zero_divisors.  Slight
haftmann@60516
   197
INCOMPATIBILITY.
haftmann@60516
   198
haftmann@60688
   199
* Class algebraic_semidom introduces common algebraic notions of
haftmann@60688
   200
integral (semi)domains, particularly units.  Although
haftmann@60517
   201
logically subsumed by fields, is is not a super class of these
haftmann@60517
   202
in order not to burden fields with notions that are trivial there.
haftmann@60688
   203
haftmann@60688
   204
* Class normalization_semidom specifies canonical representants
haftmann@60688
   205
for equivalence classes of associated elements in an integral
haftmann@60688
   206
(semi)domain.  This formalizes associated elements as well.
haftmann@60688
   207
haftmann@60688
   208
* Abstract specification of gcd/lcm operations in classes semiring_gcd,
haftmann@60688
   209
semiring_Gcd, semiring_Lcd.  Minor INCOMPATIBILITY: facts gcd_nat.commute
haftmann@60688
   210
and gcd_int.commute are subsumed by gcd.commute, as well as gcd_nat.assoc
haftmann@60688
   211
and gcd_int.assoc by gcd.assoc.
haftmann@60517
   212
haftmann@60429
   213
* Former constants Fields.divide (_ / _) and Divides.div (_ div _)
haftmann@60352
   214
are logically unified to Rings.divide in syntactic type class
haftmann@60429
   215
Rings.divide, with infix syntax (_ div _).  Infix syntax (_ / _)
haftmann@60429
   216
for field division is added later as abbreviation in class Fields.inverse.
haftmann@60516
   217
INCOMPATIBILITY,  instantiations must refer to Rings.divide rather
haftmann@60429
   218
than the former separate constants, hence infix syntax (_ / _) is usually
haftmann@60429
   219
not available during instantiation.
haftmann@60352

Mathias@60397
   221
* Library/Multiset:
Mathias@60397
   222
  - Renamed multiset inclusion operators:
Mathias@60397
   223
      < ~> <#
Mathias@60397
   224
      \<subset> ~> \<subset>#
Mathias@60397

Mathias@60397
   226
      \<le> ~> \<le>#
Mathias@60397
   227
      \<subseteq> ~> \<subseteq>#
Mathias@60397
   228
    INCOMPATIBILITY.
Mathias@60397
   229
  - "'a multiset" is no longer an instance of the "order",
Mathias@60397
   230
    "ordered_ab_semigroup_add_imp_le", "ordered_cancel_comm_monoid_diff",
Mathias@60397
   231
    "semilattice_inf", and "semilattice_sup" type classes. The theorems
Mathias@60397
   232
    previously provided by these type classes (directly or indirectly)
Mathias@60397
   233
    are now available through the "subset_mset" interpretation
Mathias@60397
   234
    (e.g. add_mono ~> subset_mset.add_mono).
Mathias@60397
   235
    INCOMPATIBILITY.
nipkow@60497
   236
  - Renamed conversions:
nipkow@60515
   237
      multiset_of ~> mset
nipkow@60515
   238
      multiset_of_set ~> mset_set
nipkow@60497
   239
      set_of ~> set_mset
nipkow@60497
   240
    INCOMPATIBILITY
Mathias@60398
   241
  - Renamed lemmas:
Mathias@60398

      mset_le_def ~> subseteq_mset_def
Mathias@60398
   243
      mset_less_def ~> subset_mset_def

    INCOMPATIBILITY
Mathias@60400
   246
  - Removed lemmas generated by lift_definition:
Mathias@60400
   247
    less_eq_multiset.abs_eq, less_eq_multiset.rsp less_eq_multiset.transfer
Mathias@60400
   248

*** ML ***
wenzelm@60793
   259
wenzelm@60802
   260
* Instantiation rules have been re-organized as follows:
wenzelm@60802
   261
wenzelm@60802
   262
  Thm.instantiate  (*low-level instantiation with named arguments*)
wenzelm@60802
   263
  Thm.instantiate' (*version with positional arguments*)
wenzelm@60802
   264
wenzelm@60802
   265
  Drule.infer_instantiate  (*instantiation with type inference*)
wenzelm@60802
   266
  Drule.infer_instantiate'  (*version with positional arguments*)
wenzelm@60802
   267
wenzelm@60802
   268
The LHS only requires variable specifications, instead of full terms.
wenzelm@60802
   269
Old cterm_instantiate is superseded by infer_instantiate.
wenzelm@60802
   270
INCOMPATIBILITY, need to re-adjust some ML names and types accordingly.
wenzelm@60802
   271
wenzelm@60793
   272
* Old tactic shorthands atac, rtac, etac, dtac, ftac have been
wenzelm@60793
   273
discontinued. INCOMPATIBILITY, use regular assume_tac, resolve_tac etc.
wenzelm@60793
   274
instead (with proper context).
wenzelm@60642
   275
wenzelm@60642
   276
* Thm.instantiate (and derivatives) no longer require the LHS of the

wenzelm@60642
   278
wenzelm@60707
   279
* Subgoal.SUBPROOF and Subgoal.FOCUS combinators use anonymous
wenzelm@60707
   280
quasi-bound variables (like the Simplifier), instead of accidentally
wenzelm@60707
   281
named local fixes. This has the potential to improve stability of proof
wenzelm@60707
   282
tools, but can also cause INCOMPATIBILITY for tools that don't observe
wenzelm@60707
   283
the proof context discipline.

*** General ***
wenzelm@57941
   291
wenzelm@59939
   292
* Local theory specification commands may have a 'private' or
wenzelm@59990
   293
'qualified' modifier to restrict name space accesses to the local scope,
wenzelm@59939
   294
as provided by some "context begin ... end" block. For example:
wenzelm@59926
   295
wenzelm@59926
   296
  context
wenzelm@59926
   297
  begin
wenzelm@59926
   298
wenzelm@59926
   299
  private definition ...
wenzelm@59926
   300
  private lemma ...
wenzelm@59926
   301
wenzelm@59990
   302
  qualified definition ...
wenzelm@59990
   303
  qualified lemma ...
wenzelm@59990
   304
wenzelm@59926
   305
  lemma ...
wenzelm@59926
   306
  theorem ...
wenzelm@59926
   307
wenzelm@59926
   308
  end
wenzelm@59926
   309
wenzelm@59901
   310
* Command 'experiment' opens an anonymous locale context with private
wenzelm@59901
   311
naming policy.
wenzelm@59901
   312
wenzelm@59951
   313
* Command 'notepad' requires proper nesting of begin/end and its proof
wenzelm@59951
   314
structure in the body: 'oops' is no longer supported here. Minor
wenzelm@59951
   315
INCOMPATIBILITY, use 'sorry' instead.
wenzelm@59951
   316
wenzelm@59951
   317
* Command 'named_theorems' declares a dynamic fact within the context,
wenzelm@59951
   318
together with an attribute to maintain the content incrementally. This
wenzelm@59951
   319
supersedes functor Named_Thms in Isabelle/ML, but with a subtle change
wenzelm@59951
   320
of semantics due to external visual order vs. internal reverse order.
wenzelm@59951
   321
wenzelm@59951
   322
* 'find_theorems': search patterns which are abstractions are
wenzelm@59951
   323
schematically expanded before search. Search results match the naive
wenzelm@59951
   324
expectation more closely, particularly wrt. abbreviations.
wenzelm@59951
   325
INCOMPATIBILITY.
wenzelm@59648
   326
wenzelm@59569
   327
* Commands 'method_setup' and 'attribute_setup' now work within a local
wenzelm@59569
   328
theory context.
wenzelm@57941
   329
wenzelm@58928
   330
* Outer syntax commands are managed authentically within the theory
wenzelm@59569
   331
context, without implicit global state. Potential for accidental
wenzelm@58928
   332
INCOMPATIBILITY, make sure that required theories are really imported.
wenzelm@58928
   333
wenzelm@60115
   334
* Historical command-line terminator ";" is no longer accepted (and
wenzelm@60115
   335
already used differently in Isar). Minor INCOMPATIBILITY, use "isabelle
wenzelm@60115
   336
update_semicolons" to remove obsolete semicolons from old theory
wenzelm@60115
   337
sources.
wenzelm@60115
   338
wenzelm@59951
   339
* Structural composition of proof methods (meth1; meth2) in Isar
wenzelm@59951
   340
corresponds to (tac1 THEN_ALL_NEW tac2) in ML.
haftmann@59105
   341
wenzelm@60119
   342
* The Eisbach proof method language allows to define new proof methods
wenzelm@60119
   343
by combining existing ones with their usual syntax. The "match" proof
wenzelm@60119
   344
method provides basic fact/term matching in addition to
wenzelm@60119
   345
premise/conclusion matching through Subgoal.focus, and binds fact names
wenzelm@60288
   346
from matches as well as term patterns within matches. The Isabelle
wenzelm@60288
   347
documentation provides an entry "eisbach" for the Eisbach User Manual.
wenzelm@60288
   348
Sources and various examples are in ~~/src/HOL/Eisbach/.

*** Prover IDE -- Isabelle/Scala/jEdit ***
wenzelm@58524
   352
wenzelm@59569
   353
* Improved folding mode "isabelle" based on Isar syntax. Alternatively,
wenzelm@59569
   354
the "sidekick" mode may be used for document structure.
wenzelm@59569
   355
wenzelm@59569
   356
* Extended bracket matching based on Isar language structure. System
wenzelm@59569
   357
option jedit_structure_limit determines maximum number of lines to scan
wenzelm@59569
   358
in the buffer.
wenzelm@58758
   359
wenzelm@58540
   360
* Support for BibTeX files: context menu, context-sensitive token
wenzelm@58540
   361
marker, SideKick parser.
wenzelm@58524
   362
wenzelm@58551
   363
* Document antiquotation @{cite} provides formal markup, which is
wenzelm@60265
   364
interpreted semi-formally based on .bib files that happen to be open in
wenzelm@60265
   365
the editor (hyperlinks, completion etc.).
wenzelm@58551
   366
wenzelm@58785
   367
* Less waste of vertical space via negative line spacing (see Global
wenzelm@58785
   368
Options / Text Area).
wenzelm@58785
   369
wenzelm@60089
   370
* Improved graphview panel with optional output of PNG or PDF, for
wenzelm@60273
   371
display of 'thy_deps', 'class_deps' etc.
wenzelm@60009
   372
wenzelm@60115
   373
* The commands 'thy_deps' and 'class_deps' allow optional bounds to
wenzelm@60115
   374
restrict the visualized hierarchy.
wenzelm@60093
   375
wenzelm@60072
   376
* Improved scheduling for asynchronous print commands (e.g. provers
wenzelm@60072
   377
managed by the Sledgehammer panel) wrt. ongoing document processing.
wenzelm@60072
   378
wenzelm@58524
   379
wenzelm@59951
   380
*** Document preparation ***
wenzelm@59951
   381
wenzelm@59951
   382
* Document markup commands 'chapter', 'section', 'subsection',
wenzelm@59951
   383
'subsubsection', 'text', 'txt', 'text_raw' work uniformly in any
wenzelm@59951
   384
context, even before the initial 'theory' command. Obsolete proof
wenzelm@59951
   385
commands 'sect', 'subsect', 'subsubsect', 'txt_raw' have been
wenzelm@59951
   386
discontinued, use 'section', 'subsection', 'subsubsection', 'text_raw'
wenzelm@59951
   387
instead. The old 'header' command is still retained for some time, but
wenzelm@59951
   388
should be replaced by 'chapter', 'section' etc. (using "isabelle
wenzelm@59951
   389
update_header"). Minor INCOMPATIBILITY.
wenzelm@59951
   390
wenzelm@60009
   391
* Official support for "tt" style variants, via \isatt{...} or
wenzelm@60009
   392
\begin{isabellett}...\end{isabellett}. The somewhat fragile \verb or
wenzelm@60009
   393
verbatim environment of LaTeX is no longer used. This allows @{ML} etc.
wenzelm@60009
   394
as argument to other macros (such as footnotes).
wenzelm@60009
   395
wenzelm@60009
   396
* Document antiquotation @{verbatim} prints ASCII text literally in "tt"
wenzelm@60009
   397
style.
wenzelm@60009
   398
wenzelm@60009
   399
* Discontinued obsolete option "document_graph": session_graph.pdf is
wenzelm@60009
   400
produced unconditionally for HTML browser_info and PDF-LaTeX document.
wenzelm@60009
   401
wenzelm@59951
   402
* Diagnostic commands and document markup commands within a proof do not
wenzelm@59951
   403
affect the command tag for output. Thus commands like 'thm' are subject
wenzelm@59951
   404
to proof document structure, and no longer "stick out" accidentally.
wenzelm@59951
   405
Commands 'text' and 'txt' merely differ in the LaTeX style, not their
wenzelm@59951
   406
tags. Potential INCOMPATIBILITY in exotic situations.
wenzelm@59951
   407
wenzelm@59951
   408
* System option "pretty_margin" is superseded by "thy_output_margin",
wenzelm@59951
   409
which is also accessible via document antiquotation option "margin".
wenzelm@59951
   410
Only the margin for document output may be changed, but not the global
wenzelm@59951
   411
pretty printing: that is 76 for plain console output, and adapted
wenzelm@59951
   412
dynamically in GUI front-ends. Implementations of document
wenzelm@59951
   413
antiquotations need to observe the margin explicitly according to
wenzelm@59951
   414
Thy_Output.string_of_margin. Minor INCOMPATIBILITY.
wenzelm@59951
   415
wenzelm@60299
   416
* Specification of 'document_files' in the session ROOT file is
wenzelm@60299
   417
mandatory for document preparation. The legacy mode with implicit
wenzelm@60299
   418
copying of the document/ directory is no longer supported. Minor
wenzelm@60299
   419
INCOMPATIBILITY.

haftmann@58202
   422
*** Pure ***
haftmann@58202
   423
wenzelm@59835
   424
* Proof methods with explicit instantiation ("rule_tac", "subgoal_tac"
wenzelm@59835
   425
etc.) allow an optional context of local variables ('for' declaration):
wenzelm@59835
   426
these variables become schematic in the instantiated theorem; this
wenzelm@59835
   427
behaviour is analogous to 'for' in attributes "where" and "of".
wenzelm@59835
   428
Configuration option rule_insts_schematic (default false) controls use
wenzelm@59835
   429
of schematic variables outside the context. Minor INCOMPATIBILITY,
wenzelm@59835
   430
declare rule_insts_schematic = true temporarily and update to use local
wenzelm@59835
   431
variable declarations or dummy patterns instead.
wenzelm@59835
   432
wenzelm@60009
   433
* Explicit instantiation via attributes "where", "of", and proof methods
wenzelm@60009
   434
"rule_tac" with derivatives like "subgoal_tac" etc. admit dummy patterns
wenzelm@60009
   435
("_") that stand for anonymous local variables.
wenzelm@60009
   436
wenzelm@59951
   437
* Generated schematic variables in standard format of exported facts are
wenzelm@59951
   438
incremented to avoid material in the proof context. Rare
wenzelm@59951
   439
INCOMPATIBILITY, explicit instantiation sometimes needs to refer to
wenzelm@59951
   440
different index.
wenzelm@59951
   441
wenzelm@60010
   442
* Lexical separation of signed and unsigned numerals: categories "num"
wenzelm@60010
   443
and "float" are unsigned. INCOMPATIBILITY: subtle change in precedence
wenzelm@60010
   444
of numeral signs, particularly in expressions involving infix syntax
wenzelm@60010
   445
like "(- 1) ^ n".
haftmann@58410
   446
wenzelm@58421
   447
* Old inner token category "xnum" has been discontinued.  Potential
wenzelm@58421
   448
INCOMPATIBILITY for exotic syntax: may use mixfix grammar with "num"
wenzelm@58421
   449
token category instead.

blanchet@58373
   457
    by "~~/src/HOL/Library/Old_Datatype.thy". See

    INCOMPATIBILITY.
blanchet@58044

    consequences of other set rules "by auto".
blanchet@58044
   480
    INCOMPATIBILITY.
blanchet@58044
   481
  - The rule "set_cases" is now registered with the "[cases set]"

   484
    assumption is of the form "w : set ws" and the method "cases w"
blanchet@57990
   485
    is invoked). The solution is to specify the case rule explicitly
blanchet@57990

    were removed. Changed definitions of the relators rel_prod and
wenzelm@60114
   500
    rel_sum (using inductive).

   526
blanchet@57737
   527
* Sledgehammer:
blanchet@59511

   540
  - The old 'smt' method has been renamed 'old_smt' and moved to
wenzelm@59569
   541
    'src/HOL/Library/Old_SMT.thy'. It is provided for compatibility,
wenzelm@59569
   542
    until applications have been ported to use the new 'smt' method. For
wenzelm@59569
   543
    the method to work, an older version of Z3 (e.g. Z3 3.2 or 4.0) must
wenzelm@59569
   544
    be installed, and the environment variable "OLD_Z3_SOLVER" must
wenzelm@59569

* Lifting: command 'lift_definition' allows to execute lifted constants
wenzelm@60261
   555
that have as a return type a datatype containing a subtype. This
wenzelm@60261
   556
overcomes long-time limitations in the area of code generation and
wenzelm@60261
   557
lifting, and avoids tedious workarounds.

   561
Minor INCOMPATIBILITY.

wenzelm@60009
   564
wenzelm@60009
   565
* field_simps: Use NO_MATCH-simproc for distribution rules, to avoid

non-termination in case of distributing a division. With this change
wenzelm@60009
   567
field_simps is in some cases slightly less powerful, if it fails try to

* The factorial function, "fact", now has type "nat => 'a" (of a sort
wenzelm@60009
   596
that admits numeric types including nat, int, real and complex.
wenzelm@60009
   597
INCOMPATIBILITY: an expression such as "fact 3 = 6" may require a type
wenzelm@60009
   598
constraint, and the combination "real (fact k)" is likely to be
wenzelm@60009

"nat o ceiling" instead. A few of the lemmas have been retained and
wenzelm@60009

* Library/Multiset:
blanchet@59813
   652
  - Introduced "replicate_mset" operation.
blanchet@59813
   653
  - Introduced alternative characterizations of the multiset ordering in
blanchet@59813
   654
    "Library/Multiset_Order".
blanchet@59958

    INCOMPATIBILITY.
blanchet@59813

wenzelm@60009
   683
use local CSDP executable, which is much faster than the NEOS server.
wenzelm@60009
   684
The "sos_cert" functionality is invoked as "sos" with additional

wenzelm@60009
   687
* HOL-Decision_Procs: New counterexample generator quickcheck
wenzelm@60009
   688
[approximation] for inequalities of transcendental functions. Uses
wenzelm@60009
   689
hardware floating point arithmetic to randomly discover potential

* HOL-Probability: Reworked measurability prover
wenzelm@60010
   695
  - applies destructor rules repeatedly
hoelzl@59354
   696
  - removed application splitting (replaced by destructor rule)
wenzelm@59569

*** ML ***
blanchet@58066
   705
wenzelm@60009
   706
* Subtle change of name space policy: undeclared entries are now
wenzelm@60009
   707
considered inaccessible, instead of accessible via the fully-qualified
wenzelm@60009
   708
internal name. This mainly affects Name_Space.intern (and derivatives),
wenzelm@60009
   709
which may produce an unexpected Long_Name.hidden prefix. Note that
wenzelm@60010
   710
contemporary applications use the strict Name_Space.check (and
wenzelm@60009
   711
derivatives) instead, which is not affected by the change. Potential
wenzelm@60009
   712
INCOMPATIBILITY in rare applications of Name_Space.intern.
wenzelm@59951
   713
wenzelm@60094
   714
* Subtle change of error semantics of Toplevel.proof_of: regular user

   715
ERROR instead of internal Toplevel.UNDEF.
wenzelm@60094
   716
wenzelm@59951
   717
* Basic combinators map, fold, fold_map, split_list, apply are available
wenzelm@59951
   718
as parameterized antiquotations, e.g. @{map 4} for lists of quadruples.
wenzelm@59951

INCOMPATIBILITY.
wenzelm@59951
   722
wenzelm@59951
   723
* Former combinators NAMED_CRITICAL and CRITICAL for central critical
wenzelm@59951
   724
sections have been discontinued, in favour of the more elementary
wenzelm@59951
   725
Multithreading.synchronized and its high-level derivative
wenzelm@59951
   726
Synchronized.var (which is usually sufficient in applications). Subtle
wenzelm@59951
   727
INCOMPATIBILITY: synchronized access needs to be atomic and cannot be
wenzelm@59951
   728
nested.
wenzelm@59951
   729
wenzelm@60009
   730
* Synchronized.value (ML) is actually synchronized (as in Scala): subtle
wenzelm@60009
   731
change of semantics with minimal potential for INCOMPATIBILITY.
wenzelm@59899
   732
wenzelm@59621
   733
* The main operations to certify logical entities are Thm.ctyp_of and
wenzelm@59621
   734
Thm.cterm_of with a local context; old-style global theory variants are
wenzelm@59621
   735
available as Thm.global_ctyp_of and Thm.global_cterm_of.
wenzelm@59621
   736
INCOMPATIBILITY.
wenzelm@59621

* Elementary operations in module Thm are no longer pervasive.
wenzelm@59582
   739
INCOMPATIBILITY, need to use qualified Thm.prop_of, Thm.cterm_of,

compose_tac, Splitter.split_tac etc. INCOMPATIBILITY.
wenzelm@58956
   745
blanchet@58066

blanchet@58066
   747
PARALLEL_GOALS.
blanchet@58066
   748
wenzelm@59564
   749
* Goal.prove_multi is superseded by the fully general Goal.prove_common,
wenzelm@59564
   750
which also allows to specify a fork priority.
wenzelm@59564
   751
wenzelm@59936
   752
* Antiquotation @{command_spec "COMMAND"} is superseded by
wenzelm@59936

wenzelm@59951
   767
* Discontinued old-fashioned "codegen" tool. Code generation can always
wenzelm@59951

* Support for official Standard ML within the Isabelle context.
wenzelm@57452
   791
Command 'SML_file' reads and evaluates the given Standard ML file.
wenzelm@57452
   792
Toplevel bindings are stored within the theory context; the initial
wenzelm@57452
   793
environment is restricted to the Standard ML implementation of
wenzelm@57452
   794
Poly/ML, without the add-ons of Isabelle/ML.  Commands 'SML_import'
wenzelm@57452
   795
and 'SML_export' allow to exchange toplevel bindings between the two
wenzelm@57452
   796
separate environments.  See also ~~/src/Tools/SML/Examples.thy for
wenzelm@57452
   797
some examples.
wenzelm@56499
   798
wenzelm@57504
   799
* Standard tactics and proof methods such as "clarsimp", "auto" and
wenzelm@57504
   800
"safe" now preserve equality hypotheses "x = expr" where x is a free
wenzelm@57504
   801
variable.  Locale assumptions and chained facts containing "x"
wenzelm@57504
   802
continue to be useful.  The new method "hypsubst_thin" and the
wenzelm@57504
   803
configuration option "hypsubst_thin" (within the attribute name space)
wenzelm@57504
   804
restore the previous behavior.  INCOMPATIBILITY, especially where
wenzelm@57504
   805
induction is done after these methods or when the names of free and
wenzelm@57504
   806
bound variables clash.  As first approximation, old proofs may be
wenzelm@57504
   807
repaired by "using [[hypsubst_thin = true]]" in the critical spot.
wenzelm@57504
   808
wenzelm@56232
   809
* More static checking of proof methods, which allows the system to
wenzelm@56232

processed in the original proof context as far as possible, before
wenzelm@56232
   812
operating on the goal state.  In any case, the standard discipline for
wenzelm@56232
   813
subgoal-addressing needs to be observed: no subgoals or a subgoal
wenzelm@56232
   814
number that is out of range produces an empty result sequence, not an
wenzelm@56232
   815
exception.  Potential INCOMPATIBILITY for non-conformant tactical
wenzelm@56232
   816
proof tools.
wenzelm@56232
   817
wenzelm@57452
   818
* Lexical syntax (inner and outer) supports text cartouches with
wenzelm@57452
   819
arbitrary nesting, and without escapes of quotes etc.  The Prover IDE
wenzelm@57452
   820
supports input via ` (backquote).
wenzelm@57452
   821
wenzelm@57452
   822
* The outer syntax categories "text" (for formal comments and document
wenzelm@57452
   823
markup commands) and "altstring" (for literal fact references) allow
wenzelm@57452
   824
cartouches as well, in addition to the traditional mix of quotations.
wenzelm@57452
   825
wenzelm@57452
   826
* Syntax of document antiquotation @{rail} now uses \<newline> instead
wenzelm@57452
   827
of "\\", to avoid the optical illusion of escaped backslash within
wenzelm@57491
   828
string token.  General renovation of its syntax using text cartouches.
wenzelm@57452
   829
Minor INCOMPATIBILITY.
wenzelm@57452
   830
wenzelm@57452
   831
* Discontinued legacy_isub_isup, which was a temporary workaround for
wenzelm@57452
   832
Isabelle/ML in Isabelle2013-1.  The prover process no longer accepts
wenzelm@57452
   833
old identifier syntax with \<^isub> or \<^isup>.  Potential
wenzelm@57452
   834
INCOMPATIBILITY.
wenzelm@57452
   835
wenzelm@57452
   836
* Document antiquotation @{url} produces markup for the given URL,
wenzelm@57452
   837
which results in an active hyperlink within the text.
wenzelm@57452
   838
wenzelm@57452
   839
* Document antiquotation @{file_unchecked} is like @{file}, but does
wenzelm@57452
   840
not check existence within the file-system.
wenzelm@57452
   841
wenzelm@57452
   842
* Updated and extended manuals: codegen, datatypes, implementation,
wenzelm@57452
   843
isar-ref, jedit, system.

*** Prover IDE -- Isabelle/Scala/jEdit ***
wenzelm@54533
   847
wenzelm@57650
   848
* Improved Document panel: simplified interaction where every single
wenzelm@57452
   849
mouse click (re)opens document via desktop environment or as jEdit
wenzelm@57452
   850
buffer.
wenzelm@57452
   851
wenzelm@57452
   852
* Support for Navigator plugin (with toolbar buttons), with connection
wenzelm@57452
   853
to PIDE hyperlinks.
wenzelm@57452
   854
wenzelm@57452
   855
* Auxiliary files ('ML_file' etc.) are managed by the Prover IDE.
wenzelm@57452
   856
Open text buffers take precedence over copies within the file-system.
wenzelm@57452
   857
wenzelm@57452
   858
* Improved support for Isabelle/ML, with jEdit mode "isabelle-ml" for
wenzelm@57452
   859
auxiliary ML files.
wenzelm@57423
   860
wenzelm@57423
   861
* Improved syntactic and semantic completion mechanism, with simple
wenzelm@57423
   862
templates, completion language context, name-space completion,
wenzelm@57423
   863
file-name completion, spell-checker completion.
wenzelm@57423
   864
wenzelm@57423
   865
* Refined GUI popup for completion: more robust key/mouse event
wenzelm@57423
   866
handling and propagation to enclosing text area -- avoid loosing
wenzelm@57423
   867
keystrokes with slow / remote graphics displays.
wenzelm@57423
   868
wenzelm@57833
   869
* Completion popup supports both ENTER and TAB (default) to select an
wenzelm@57833
   870
item, depending on Isabelle options.
wenzelm@57833
   871
wenzelm@57423
   872
* Refined insertion of completion items wrt. jEdit text: multiple
wenzelm@57423
   873
selections, rectangular selections, rectangular selection as "tall
wenzelm@57423
   874
caret".
wenzelm@56342
   875
wenzelm@56580
   876
* Integrated spell-checker for document text, comments etc. with
wenzelm@57423
   877
completion popup and context-menu.
wenzelm@56554
   878
wenzelm@56879
   879
* More general "Query" panel supersedes "Find" panel, with GUI access
wenzelm@56879
   880
to commands 'find_theorems' and 'find_consts', as well as print
wenzelm@56879
   881
operations for the context.  Minor incompatibility in keyboard
wenzelm@56879
   882
shortcuts etc.: replace action isabelle-find by isabelle-query.
wenzelm@56761
   883
wenzelm@56901
   884
* Search field for all output panels ("Output", "Query", "Info" etc.)
wenzelm@56901
   885
to highlight text via regular expression.
wenzelm@56901
   886
wenzelm@54881
   887
* Option "jedit_print_mode" (see also "Plugin Options / Isabelle /
wenzelm@54881
   888
General") allows to specify additional print modes for the prover
wenzelm@54881
   889
process, without requiring old-fashioned command-line invocation of
wenzelm@54881
   890
"isabelle jedit -m MODE".
wenzelm@54881
   891
wenzelm@56505
   892
* More support for remote files (e.g. http) using standard Java
wenzelm@56505
   893
networking operations instead of jEdit virtual file-systems.
wenzelm@56505
   894
wenzelm@57822
   895
* Empty editors buffers that are no longer required (e.g.\ via theory
wenzelm@57822
   896
imports) are automatically removed from the document model.
wenzelm@57822
   897
wenzelm@57869
   898
* Improved monitor panel.
wenzelm@57869
   899
wenzelm@56838
   900
* Improved Console/Scala plugin: more uniform scala.Console output,
wenzelm@56838
   901
more robust treatment of threads and interrupts.
wenzelm@56838
   902
wenzelm@56939
   903
* Improved management of dockable windows: clarified keyboard focus
wenzelm@56939
   904
and window placement wrt. main editor view; optional menu item to
wenzelm@56939
   905
"Detach" a copy where this makes sense.
wenzelm@56939
   906
wenzelm@57452
   907
* New Simplifier Trace panel provides an interactive view of the
wenzelm@57591
   908
simplification process, enabled by the "simp_trace_new" attribute
wenzelm@57452
   909
within the context.

*** Pure ***
wenzelm@55001
   913
wenzelm@57504
   914
* Low-level type-class commands 'classes', 'classrel', 'arities' have
wenzelm@57504
   915
been discontinued to avoid the danger of non-trivial axiomatization
wenzelm@57504
   916
that is not immediately visible.  INCOMPATIBILITY, use regular
wenzelm@57504
   917
'instance' command with proof.  The required OFCLASS(...) theorem
wenzelm@57504
   918
might be postulated via 'axiomatization' beforehand, or the proof
wenzelm@57504
   919
finished trivially if the underlying class definition is made vacuous
wenzelm@57504
   920
(without any assumptions).  See also Isabelle/ML operations
wenzelm@57504
   921
Axclass.class_axiomatization, Axclass.classrel_axiomatization,
wenzelm@57504
   922
Axclass.arity_axiomatization.
wenzelm@57504
   923
wenzelm@56245
   924
* Basic constants of Pure use more conventional names and are always
wenzelm@56245
   925
qualified.  Rare INCOMPATIBILITY, but with potentially serious
wenzelm@56245
   926
consequences, notably for tools in Isabelle/ML.  The following
wenzelm@56245
   927
renaming needs to be applied:
wenzelm@56245
   928
wenzelm@56245
   929
  ==             ~>  Pure.eq
wenzelm@56245
   930
  ==>            ~>  Pure.imp
wenzelm@56245
   931
  all            ~>  Pure.all
wenzelm@56245
   932
  TYPE           ~>  Pure.type
wenzelm@56245
   933
  dummy_pattern  ~>  Pure.dummy_pattern
wenzelm@56245
   934
wenzelm@56245
   935
Systematic porting works by using the following theory setup on a
wenzelm@56245
   936
*previous* Isabelle version to introduce the new name accesses for the
wenzelm@56245
   937
old constants:
wenzelm@56245
   938
wenzelm@56245
   939
setup {*
wenzelm@56245
   940
  fn thy => thy
wenzelm@56245
   941
    |> Sign.root_path
wenzelm@56245
   942
    |> Sign.const_alias (Binding.qualify true "Pure" @{binding eq}) "=="
wenzelm@56245
   943
    |> Sign.const_alias (Binding.qualify true "Pure" @{binding imp}) "==>"
wenzelm@56245
   944
    |> Sign.const_alias (Binding.qualify true "Pure" @{binding all}) "all"
wenzelm@56245
   945
    |> Sign.restore_naming thy
wenzelm@56245
   946
*}
wenzelm@56245
   947
wenzelm@56245
   948
Thus ML antiquotations like @{const_name Pure.eq} may be used already.
wenzelm@56245
   949
Later the application is moved to the current Isabelle version, and
wenzelm@56245
   950
the auxiliary aliases are deleted.
wenzelm@56245
   951
wenzelm@55143
   952
* Attributes "where" and "of" allow an optional context of local
wenzelm@55143
   953
variables ('for' declaration): these variables become schematic in the
wenzelm@55143
   954
instantiated theorem.
wenzelm@55143
   955
wenzelm@55152
   956
* Obsolete attribute "standard" has been discontinued (legacy since
wenzelm@55152
   957
Isabelle2012).  Potential INCOMPATIBILITY, use explicit 'for' context
wenzelm@55152
   958
where instantiations with schematic variables are intended (for
wenzelm@55152
   959
declaration commands like 'lemmas' or attributes like "of").  The
wenzelm@55152
   960
following temporary definition may help to port old applications:
wenzelm@55152
   961
wenzelm@55152
   962
  attribute_setup standard =
wenzelm@55152
   963
    "Scan.succeed (Thm.rule_attribute (K Drule.export_without_context))"
wenzelm@55152
   964
wenzelm@55001
   965
* More thorough check of proof context for goal statements and
wenzelm@55006
   966
attributed fact expressions (concerning background theory, declared
wenzelm@55006
   967
hyps).  Potential INCOMPATIBILITY, tools need to observe standard
wenzelm@55006
   968
context discipline.  See also Assumption.add_assumes and the more
wenzelm@55006
   969
primitive Thm.assume_hyps.
wenzelm@55001
   970
wenzelm@55108
   971
* Inner syntax token language allows regular quoted strings "..."
wenzelm@55108
   972
(only makes sense in practice, if outer syntax is delimited
wenzelm@57452
   973
differently, e.g. via cartouches).
wenzelm@57452
   974
wenzelm@57504
   975
* Command 'print_term_bindings' supersedes 'print_binds' for clarity,
wenzelm@57504
   976
but the latter is retained some time as Proof General legacy.
wenzelm@57504
   977
wenzelm@57452
   978
* Code generator preprocessor: explicit control of simp tracing on a
wenzelm@57452
   979
per-constant basis.  See attribute "code_preproc".

wenzelm@57452
  1007
wenzelm@57504

* Renamed command 'enriched_type' to 'functor'. INCOMPATIBILITY.
wenzelm@57504
  1009
wenzelm@57504
  1010
* The symbol "\<newline>" may be used within char or string literals
wenzelm@57504

to represent (Char Nibble0 NibbleA), i.e. ASCII newline.
wenzelm@57504

wenzelm@57452

* Simplifier: Enhanced solver of preconditions of rewrite rules can
wenzelm@57452
  1016

wenzelm@57452
  1017
behaviour of the simplifier can be restored like this: declare/using
wenzelm@57452
  1018
[[simp_legacy_precond]].  This configuration option will disappear

  1183
4.3). The new proof method is called "smt2". CVC3 and CVC4 are also
wenzelm@57508
  1184
supported as oracles. Yices is no longer supported, because no version
wenzelm@57508

blanchet@57532
  1195
    . New SML-based learning algorithms eliminate the dependency on
wenzelm@57508

      Python and increase performance and reliability.
wenzelm@57508
  1197
    . MaSh and MeSh are now used by default together with the
wenzelm@57508
  1198
      traditional MePo (Meng-Paulson) relevance filter. To disable
wenzelm@57508

wenzelm@57508
  1211
* Nitpick:
wenzelm@57508

  - Fixed soundness bug whereby mutually recursive datatypes could
wenzelm@57508
  1213
    take infinite values.
wenzelm@57508
  1214
  - Fixed soundness bug with low-level number functions such as
wenzelm@57508

    "Abs_Integ" and "Rep_Integ".
wenzelm@57508
  1216
  - Removed "std" option.

  1218
    "hide_types".
wenzelm@57508
  1219
wenzelm@57508

wenzelm@57508
  1222
wenzelm@57508

* Adjustion of INF and SUP operations:
wenzelm@57508
  1226
  - Elongated constants INFI and SUPR to INFIMUM and SUPREMUM.
wenzelm@57508
  1227
  - Consolidated theorem names containing INFI and SUPR: have INF and
wenzelm@57508
  1228
    SUP instead uniformly.
wenzelm@57508
  1229
  - More aggressive normalization of expressions involving INF and Inf
wenzelm@57508
  1230
    or SUP and Sup.
wenzelm@57508
  1231
  - INF_image and SUP_image do not unfold composition.
wenzelm@57508
  1232
  - Dropped facts INF_comp, SUP_comp.
wenzelm@57508
  1233
  - Default congruence rules strong_INF_cong and strong_SUP_cong, with
wenzelm@57508
  1234
    simplifier implication in premises.  Generalize and replace former
wenzelm@57508

* Subtle change of semantics of Thm.eq_thm: theory stamps are not
wenzelm@57504
  1779
compared (according to Thm.thm_ord), but assumed to be covered by the
wenzelm@57504
  1780
current background theory.  Thus equivalent data produced in different
wenzelm@57504
  1781
branches of the theory graph usually coincides (e.g. relevant for
wenzelm@57504
  1782
theory merge).  Note that the softer Thm.eq_thm_prop is often more

variables that are meant to become schematic need to be given as

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

  1793
This corresponds to Isar attributes "where" and "of" with 'for'

wenzelm@56069
  1819
wenzelm@56071
  1820
* ML antiquotation @{here} refers to its source position, which is
wenzelm@56071
  1821
occasionally useful for experimentation and diagnostic purposes.
wenzelm@56071
  1822
wenzelm@56135
  1823
* ML antiquotation @{path} produces a Path.T value, similarly to
wenzelm@56135
  1824
Path.explode, but with compile-time check against the file-system and
wenzelm@56135
  1825
some PIDE markup.  Note that unlike theory source, ML does not have a
wenzelm@56135
  1826
well-defined master directory, so an absolute symbolic path
wenzelm@56135
  1827
specification is usually required, e.g. "~~/src/HOL".
wenzelm@56135
  1828
wenzelm@56399
  1829
* ML antiquotation @{print} inlines a function to print an arbitrary
wenzelm@56399
  1830
ML value, which is occasionally useful for diagnostic or demonstration
wenzelm@56399
  1831
purposes.

* Proof General with its traditional helper scripts is now an optional
wenzelm@57504
  1837
Isabelle component, e.g. see ProofGeneral-4.2-2 from the Isabelle
wenzelm@57504
  1838
component repository http://isabelle.in.tum.de/components/.  Note that
wenzelm@57504
  1839
the "system" manual provides general explanations about add-on
wenzelm@57504
  1840
components, especially those that are not bundled with the release.
wenzelm@57443
  1841
wenzelm@56439
  1842
* The raw Isabelle process executable has been renamed from
wenzelm@56439
  1843
"isabelle-process" to "isabelle_process", which conforms to common
wenzelm@56439
  1844
shell naming conventions, and allows to define a shell function within
wenzelm@56439
  1845
the Isabelle environment to avoid dynamic path lookup.  Rare
wenzelm@57504
  1846
incompatibility for old tools that do not use the ISABELLE_PROCESS
wenzelm@57504
  1847
settings variable.
wenzelm@56439
  1848
wenzelm@57439
  1849
* Former "isabelle tty" has been superseded by "isabelle console",
wenzelm@57439
  1850
with implicit build like "isabelle jedit", and without the mostly
wenzelm@57439
  1851
obsolete Isar TTY loop.
wenzelm@57439
  1852
wenzelm@57452
  1853
* Simplified "isabelle display" tool.  Settings variables DVI_VIEWER
wenzelm@57452
  1854
and PDF_VIEWER now refer to the actual programs, not shell
wenzelm@57452
  1855
command-lines.  Discontinued option -c: invocation may be asynchronous
wenzelm@57452
  1856
via desktop environment, without any special precautions.  Potential
wenzelm@57452
  1857
INCOMPATIBILITY with ambitious private settings.
wenzelm@57452
  1858
wenzelm@57413
  1859
* Removed obsolete "isabelle unsymbolize".  Note that the usual format
wenzelm@57413
  1860
for email communication is the Unicode rendering of Isabelle symbols,
wenzelm@57413
  1861
as produced by Isabelle/jEdit, for example.
wenzelm@57413
  1862
wenzelm@57452
  1863
* Removed obsolete tool "wwwfind". Similar functionality may be
wenzelm@57452
  1864
integrated into Isabelle/jEdit eventually.
wenzelm@57452
  1865
wenzelm@57452
  1866
* Improved 'display_drafts' concerning desktop integration and
wenzelm@57452
  1867
repeated invocation in PIDE front-end: re-use single file
wenzelm@57452
  1868
$ISABELLE_HOME_USER/tmp/drafts.pdf and corresponding views.
wenzelm@57084
  1869
wenzelm@57452
  1870
* Session ROOT specifications require explicit 'document_files' for
wenzelm@57452
  1871
robust dependencies on LaTeX sources.  Only these explicitly given
wenzelm@57452
  1872
files are copied to the document output directory, before document
wenzelm@57452
  1873
processing is started.
wenzelm@57452
  1874
wenzelm@57504
  1875

  1886
e.g. non-terminating 'by' steps.
wenzelm@54639
  1887

  1912
*** General ***
wenzelm@51293
  1913
wenzelm@53971
  1914
* Discontinued obsolete 'uses' within theory header.  Note that
wenzelm@53971
  1915
commands like 'ML_file' work without separate declaration of file
wenzelm@53971
  1916
dependencies.  Minor INCOMPATIBILITY.
wenzelm@53971
  1917
wenzelm@53971
  1918
* Discontinued redundant 'use' command, which was superseded by
wenzelm@53971

'ML_file' in Isabelle2013.  Minor INCOMPATIBILITY.
wenzelm@53971
  1920
wenzelm@53016
  1921
* Simplified subscripts within identifiers, using plain \<^sub>
wenzelm@53016
  1922
instead of the second copy \<^isub> and \<^isup>.  Superscripts are
wenzelm@53016
  1923
only for literal tokens within notation; explicit mixfix annotations
wenzelm@53016
  1924
for consts or fixed variables may be used as fall-back for unusual
wenzelm@53016
  1925
names.  Obsolete \<twosuperior> has been expanded to \<^sup>2 in
wenzelm@53016
  1926
Isabelle/HOL.  INCOMPATIBILITY, use "isabelle update_sub_sup" to
wenzelm@53016
  1927
standardize symbols as a starting point for further manual cleanup.
wenzelm@53016
  1928
The ML reference variable "legacy_isub_isup" may be set as temporary
wenzelm@53016
  1929
workaround, to make the prover accept a subset of the old identifier
wenzelm@53016
  1930
syntax.
wenzelm@53016
  1931
wenzelm@53021
  1932
* Document antiquotations: term style "isub" has been renamed to
wenzelm@53021
  1933
"sub".  Minor INCOMPATIBILITY.
wenzelm@53021
  1934
wenzelm@52487
  1935
* Uniform management of "quick_and_dirty" as system option (see also
wenzelm@52487
  1936
"isabelle options"), configuration option within the context (see also
wenzelm@52487
  1937
Config.get in Isabelle/ML), and attribute in Isabelle/Isar.  Minor
wenzelm@52487
  1938
INCOMPATIBILITY, need to use more official Isabelle means to access
wenzelm@52487
  1939
quick_and_dirty, instead of historical poking into mutable reference.
wenzelm@52059
  1940
wenzelm@52060
  1941
* Renamed command 'print_configs' to 'print_options'.  Minor
wenzelm@52060
  1942
INCOMPATIBILITY.
wenzelm@52060
  1943
wenzelm@52430
  1944
* Proper diagnostic command 'print_state'.  Old 'pr' (with its
wenzelm@52430
  1945
implicit change of some global references) is retained for now as
wenzelm@52430
  1946
control command, e.g. for ProofGeneral 3.7.x.
wenzelm@52430
  1947
wenzelm@52549
  1948
* Discontinued 'print_drafts' command with its old-fashioned PS output
wenzelm@52549
  1949
and Unix command-line print spooling.  Minor INCOMPATIBILITY: use
wenzelm@52549
  1950
'display_drafts' instead and print via the regular document viewer.
wenzelm@52549
  1951
wenzelm@53971
  1952
* Updated and extended "isar-ref" and "implementation" manual,
wenzelm@53971

  1959
Documentation panel.
wenzelm@53852
  1960
wenzelm@53971
  1961
* Dockable window "Documentation" provides access to Isabelle
wenzelm@53971
  1962

wenzelm@52646
  1963
wenzelm@52949
  1964
* Dockable window "Find" provides query operations for formal entities
wenzelm@52949
  1965
(GUI front-end to 'find_theorems' command).
wenzelm@52949
  1966
wenzelm@53050
  1967
* Dockable window "Sledgehammer" manages asynchronous / parallel
wenzelm@53050
  1968
sledgehammer runs over existing document sources, independently of
wenzelm@53050
  1969
normal editing and checking process.
wenzelm@53050
  1970
wenzelm@51533
  1971
* Dockable window "Timing" provides an overview of relevant command
wenzelm@54332
  1972
timing information, depending on option jedit_timing_threshold.  The
wenzelm@54332
  1973
same timing information is shown in the extended tooltip of the
wenzelm@54332
  1974
command keyword, when hovering the mouse over it while the CONTROL or
wenzelm@54332
  1975
COMMAND modifier is pressed.
wenzelm@51533
  1976
wenzelm@53971
  1977
* Improved dockable window "Theories": Continuous checking of proof
wenzelm@53971
  1978
document (visible and required parts) may be controlled explicitly,
wenzelm@53971
  1979
using check box or shortcut "C+e ENTER".  Individual theory nodes may
wenzelm@53971
  1980
be marked explicitly as required and checked in full, using check box
wenzelm@53971
  1981
or shortcut "C+e SPACE".
wenzelm@53971
  1982
wenzelm@54305
  1983
* Improved completion mechanism, which is now managed by the
wenzelm@54305
  1984
Isabelle/jEdit plugin instead of SideKick.  Refined table of Isabelle
wenzelm@54305
  1985
symbol abbreviations (see $ISABELLE_HOME/etc/symbols).
wenzelm@54305
  1986
wenzelm@54319
  1987
* Standard jEdit keyboard shortcut C+b complete-word is remapped to
wenzelm@54319
  1988
isabelle.complete for explicit completion in Isabelle sources.
wenzelm@54319
  1989
INCOMPATIBILITY wrt. jEdit defaults, may have to invent new shortcuts
wenzelm@54319
  1990
to resolve conflict.
wenzelm@54319
  1991
wenzelm@54305
  1992
* Improved support of various "minor modes" for Isabelle NEWS,
wenzelm@54305
  1993
options, session ROOT etc., with completion and SideKick tree view.
wenzelm@54305
  1994
wenzelm@53971
  1995
* Strictly monotonic document update, without premature cancellation of
wenzelm@53971
  1996
running transactions that are still needed: avoid reset/restart of
wenzelm@53971
  1997
such command executions while editing.
wenzelm@53271
  1998
wenzelm@53971
  1999
* Support for asynchronous print functions, as overlay to existing
wenzelm@53971
  2000

wenzelm@53971
  2001
wenzelm@53971
  2002
* Support for automatic tools in HOL, which try to prove or disprove
wenzelm@53971
  2003
toplevel theorem statements.
wenzelm@53971
  2004
wenzelm@53971
  2005
* Action isabelle.reset-font-size resets main text area font size
wenzelm@54365
  2006
according to Isabelle/Scala plugin option "jedit_font_reset_size" (see
wenzelm@54365
  2007
also "Plugin Options / Isabelle / General").  It can be bound to some
wenzelm@54365
  2008
keyboard shortcut by the user (e.g. C+0 and/or C+NUMPAD0).
wenzelm@53971
  2009
wenzelm@53971
  2010
* File specifications in jEdit (e.g. file browser) may refer to
wenzelm@54351
  2011
$ISABELLE_HOME and $ISABELLE_HOME_USER on all platforms.  Discontinued
wenzelm@54351
  2012
obsolete $ISABELLE_HOME_WINDOWS variable.
wenzelm@53971
  2013
wenzelm@53971

ballarin@54049
  2024
In particular, 'interpretation' allows for non-persistent
ballarin@54049
  2025
interpretation within "context ... begin ... end" blocks offering a

wenzelm@53971
  2039
state of Proofterm.proofs is persistently compiled into logic images
wenzelm@53971
  2040
as required, notably HOL-Proofs.  Users no longer need to change

  2041
Proofterm.proofs dynamically.  Minor INCOMPATIBILITY.
wenzelm@53971
  2042
wenzelm@53971

on Proof.context.  Discontinued former "(advanced)" option -- this is
wenzelm@53971
  2045
now the default.  Minor INCOMPATIBILITY.

wenzelm@54032
  2063
* Nested case expressions are now translated in a separate check phase
wenzelm@54032
  2064
rather than during parsing. The data for case combinators is separated
wenzelm@54032
  2065
from the datatype package. The declaration attribute
wenzelm@54032
  2066
"case_translation" can be used to register new case combinators:
wenzelm@54032

wenzelm@53160
  2072
    'code_instance'.
wenzelm@53160
  2073
  - 'code_identifier' declares name hints for arbitrary identifiers in

cases rules f.cases and g.cases are generated instead of unusable
wenzelm@54032
  2097
f_g.cases which exposed internal sum types. Potential INCOMPATIBILITY,
wenzelm@54032
  2098
in the case that the unusable rule was used nevertheless.
wenzelm@54032

wenzelm@54032
  2100
* Function package: For each function f, new rules f.elims are
wenzelm@54032
  2101
generated, which eliminate equalities of the form "f x = t".
wenzelm@54032
  2102
wenzelm@54032
  2103
* New command 'fun_cases' derives ad-hoc elimination rules for
wenzelm@54032
  2104
function equations as simplified instances of f.elims, analogous to
wenzelm@54032
  2105
inductive_cases.  See ~~/src/HOL/ex/Fundefs.thy for some examples.
blanchet@53307

kuncar@54021
  2107
* Lifting:
kuncar@54021
  2108
  - parametrized correspondence relations are now supported:
wenzelm@54378
  2109
    + parametricity theorems for the raw term can be specified in
kuncar@54021
  2110
      the command lift_definition, which allow us to generate stronger
kuncar@54021
  2111
      transfer rules
kuncar@54021
  2112
    + setup_lifting generates stronger transfer rules if parametric
kuncar@54021
  2113
      correspondence relation can be generated
kuncar@54021
  2114
    + various new properties of the relator must be specified to support
kuncar@54021
  2115
      parametricity
kuncar@54021
  2116
    + parametricity theorem for the Quotient relation can be specified
kuncar@54021
  2117
  - setup_lifting generates domain rules for the Transfer package
kuncar@54021
  2118
  - stronger reflexivity prover of respectfulness theorems for type
kuncar@54021
  2119
    copies
kuncar@54021
  2120
  - ===> and --> are now local. The symbols can be introduced
kuncar@54021
  2121
    by interpreting the locale lifting_syntax (typically in an
kuncar@54021
  2122
    anonymous context)
wenzelm@54378
  2123
  - Lifting/Transfer relevant parts of Library/Quotient_* are now in
kuncar@54021
  2124
    Main. Potential INCOMPATIBILITY
kuncar@54021
  2125
  - new commands for restoring and deleting Lifting/Transfer context:
kuncar@54021
  2126
    lifting_forget, lifting_update
wenzelm@54378
  2127
  - the command print_quotmaps was renamed to print_quot_maps.

  2128
    INCOMPATIBILITY
kuncar@54021
  2129
kuncar@54021

* Transfer:
wenzelm@54378
  2131
  - better support for domains in Transfer: replace Domainp T
kuncar@54021
  2132
    by the actual invariant in a transferred goal
kuncar@54021
  2133
  - transfer rules can have as assumptions other transfer rules
kuncar@54021
  2134
  - Experimental support for transferring from the raw level to the
kuncar@54021
  2135
    abstract level: Transfer.transferred attribute
kuncar@54021
  2136
  - Attribute version of the transfer method: untransferred attribute

* Reification and reflection:
wenzelm@53160
  2139
  - Reification is now directly available in HOL-Main in structure
wenzelm@53160
  2140
    "Reification".
wenzelm@53160
  2141
  - Reflection now handles multiple lists with variables also.
wenzelm@53160
  2142
  - The whole reflection stack has been decomposed into conversions.
haftmann@52286
  2143
INCOMPATIBILITY.
haftmann@52286
  2144
haftmann@51489
  2145
* Revised devices for recursive definitions over finite sets:
haftmann@51489
  2146
  - Only one fundamental fold combinator on finite set remains:
haftmann@51489
  2147
    Finite_Set.fold :: ('a => 'b => 'b) => 'b => 'a set => 'b
haftmann@51489
  2148
    This is now identity on infinite sets.
wenzelm@52745
  2149
  - Locales ("mini packages") for fundamental definitions with
haftmann@51489
  2150
    Finite_Set.fold: folding, folding_idem.
haftmann@51489
  2151
  - Locales comm_monoid_set, semilattice_order_set and
haftmann@51489
  2152
    semilattice_neutr_order_set for big operators on sets.
haftmann@51489
  2153
    See theory Big_Operators for canonical examples.
haftmann@51489
  2154
    Note that foundational constants comm_monoid_set.F and
haftmann@51489
  2155
    semilattice_set.F correspond to former combinators fold_image
haftmann@51489
  2156
    and fold1 respectively.  These are now gone.  You may use
haftmann@51490
  2157
    those foundational constants as substitutes, but it is
wenzelm@53983
  2158
    preferable to interpret the above locales accordingly.
haftmann@51489
  2159
  - Dropped class ab_semigroup_idem_mult (special case of lattice,
haftmann@51489
  2160
    no longer needed in connection with Finite_Set.fold etc.)
haftmann@51489
  2161
  - Fact renames:
haftmann@51489
  2162
      card.union_inter ~> card_Un_Int [symmetric]
haftmann@51489
  2163
      card.union_disjoint ~> card_Un_disjoint
haftmann@51489
  2164
INCOMPATIBILITY.
haftmann@51489
  2165
haftmann@51487
  2166
* Locale hierarchy for abstract orderings and (semi)lattices.
haftmann@51487
  2167
wenzelm@53526
  2168
* Complete_Partial_Order.admissible is defined outside the type class
wenzelm@53526
  2169
ccpo, but with mandatory prefix ccpo. Admissibility theorems lose the
wenzelm@53526
  2170
class predicate assumption or sort constraint when possible.
Andreas@53362
  2171
INCOMPATIBILITY.
Andreas@53362
  2172
wenzelm@53160
  2173
* Introduce type class "conditionally_complete_lattice": Like a
wenzelm@53160
  2174
complete lattice but does not assume the existence of the top and
wenzelm@53160
  2175
bottom elements.  Allows to generalize some lemmas about reals and
wenzelm@53160
  2176
extended reals.  Removed SupInf and replaced it by the instantiation
wenzelm@53160
  2177
of conditionally_complete_lattice for real. Renamed lemmas about
wenzelm@53160
  2178
conditionally-complete lattice from Sup_... to cSup_... and from
wenzelm@53160
  2179
Inf_...  to cInf_... to avoid hidding of similar complete lattice
wenzelm@53160
  2180
lemmas.
wenzelm@53160
  2181
wenzelm@53160
  2182
* Introduce type class linear_continuum as combination of
wenzelm@53160
  2183
conditionally-complete lattices and inner dense linorders which have
wenzelm@53160
  2184
more than one element.  INCOMPATIBILITY.
wenzelm@53160
  2185
wenzelm@53983
  2186
* Introduced type classes order_top and order_bot. The old classes top
wenzelm@53983
  2187
and bot only contain the syntax without assumptions.  INCOMPATIBILITY:
wenzelm@53983
  2188
Rename bot -> order_bot, top -> order_top
lammich@53683
  2189
wenzelm@53160
  2190
* Introduce type classes "no_top" and "no_bot" for orderings without
wenzelm@53160
  2191
top and bottom elements.
hoelzl@51732
  2192
hoelzl@51732
  2193
* Split dense_linorder into inner_dense_order and no_top, no_bot.
hoelzl@51732
  2194
hoelzl@51732
  2195
* Complex_Main: Unify and move various concepts from
wenzelm@53160
  2196
HOL-Multivariate_Analysis to HOL-Complex_Main.
hoelzl@51732
  2197
wenzelm@53983
  2198
 - Introduce type class (lin)order_topology and
wenzelm@53983
  2199
   linear_continuum_topology.  Allows to generalize theorems about
wenzelm@53983
  2200
   limits and order.  Instances are reals and extended reals.
hoelzl@51732
  2201
hoelzl@51732
  2202
 - continuous and continuos_on from Multivariate_Analysis:
wenzelm@53983
  2203
   "continuous" is the continuity of a function at a filter.  "isCont"
wenzelm@53983
  2204
   is now an abbrevitation: "isCont x f == continuous (at _) f".
wenzelm@53983
  2205
wenzelm@53983
  2206
   Generalized continuity lemmas from isCont to continuous on an
wenzelm@53983
  2207
   arbitrary filter.
wenzelm@53983
  2208
wenzelm@53983
  2209
 - compact from Multivariate_Analysis. Use Bolzano's lemma to prove
wenzelm@53983
  2210
   compactness of closed intervals on reals. Continuous functions
wenzelm@53983
  2211
   attain infimum and supremum on compact sets. The inverse of a
wenzelm@53983
  2212
   continuous function is continuous, when the function is continuous
wenzelm@53983
  2213
   on a compact set.
hoelzl@51732
  2214
hoelzl@51732
  2215
 - connected from Multivariate_Analysis. Use it to prove the
hoelzl@51775
  2216
   intermediate value theorem. Show connectedness of intervals on
hoelzl@51775
  2217
   linear_continuum_topology).
hoelzl@51732
  2218
hoelzl@51732
  2219
 - first_countable_topology from Multivariate_Analysis. Is used to
wenzelm@53983
  2220
   show equivalence of properties on the neighbourhood filter of x and
wenzelm@53983
  2221
   on all sequences converging to x.
wenzelm@53983
  2222
wenzelm@53983
  2223
 - FDERIV: Definition of has_derivative moved to Deriv.thy. Moved
wenzelm@53983
  2224
   theorems from Library/FDERIV.thy to Deriv.thy and base the
wenzelm@53983
  2225
   definition of DERIV on FDERIV. Add variants of DERIV and FDERIV
wenzelm@53983
  2226
   which are restricted to sets, i.e. to represent derivatives from
wenzelm@53983
  2227
   left or right.
hoelzl@51732
  2228
hoelzl@51732
  2229
 - Removed the within-filter. It is replaced by the principal filter:
hoelzl@51732
  2230
hoelzl@51732
  2231
     F within X = inf F (principal X)
hoelzl@51732
  2232
hoelzl@51732
  2233
 - Introduce "at x within U" as a single constant, "at x" is now an
hoelzl@51732
  2234
   abbreviation for "at x within UNIV"
hoelzl@51732
  2235
wenzelm@53983
  2236
 - Introduce named theorem collections tendsto_intros,
wenzelm@53983
  2237
   continuous_intros, continuous_on_intros and FDERIV_intros. Theorems
wenzelm@53983
  2238
   in tendsto_intros (or FDERIV_intros) are also available as
wenzelm@53983
  2239
   tendsto_eq_intros (or FDERIV_eq_intros) where the right-hand side
wenzelm@53983
  2240
   is replaced by a congruence rule. This allows to apply them as
wenzelm@53983
  2241
   intro rules and then proving equivalence by the simplifier.
hoelzl@51732
  2242
hoelzl@51732
  2243
 - Restructured theories in HOL-Complex_Main:
hoelzl@51732
  2244
hoelzl@51732
  2245
   + Moved RealDef and RComplete into Real
hoelzl@51732
  2246
hoelzl@51732
  2247
   + Introduced Topological_Spaces and moved theorems about
hoelzl@51732
  2248
     topological spaces, filters, limits and continuity to it
hoelzl@51732
  2249
hoelzl@51732
  2250
   + Renamed RealVector to Real_Vector_Spaces
hoelzl@51732
  2251
wenzelm@53983
  2252
   + Split Lim, SEQ, Series into Topological_Spaces,
wenzelm@53983
  2253
     Real_Vector_Spaces, and Limits
hoelzl@51732
  2254
hoelzl@51732
  2255
   + Moved Ln and Log to Transcendental
hoelzl@51732
  2256
hoelzl@51732
  2257
   + Moved theorems about continuity from Deriv to Topological_Spaces
hoelzl@51732
  2258
hoelzl@51732
  2259
 - Remove various auxiliary lemmas.

  - Better support for "isar_proofs".
blanchet@55889
  2273
  - MaSh has been fined-tuned and now runs as a local server.
blanchet@51137
  2274
wenzelm@54032
  2275
* Improved support for ad hoc overloading of constants (see also

wenzelm@54032
  2278
* Library/Polynomial.thy:
wenzelm@54032
  2279
  - Use lifting for primitive definitions.
wenzelm@54032
  2280
  - Explicit conversions from and to lists of coefficients, used for
wenzelm@54032
  2281
    generated code.
wenzelm@54032
  2282
  - Replaced recursion operator poly_rec by fold_coeffs.
wenzelm@54032
  2283
  - Prefer pre-existing gcd operation for gcd.
wenzelm@54032
  2284
  - Fact renames:

* New Library/Simps_Case_Conv.thy: Provides commands simps_of_case and
wenzelm@54032
  2291
case_of_simps to convert function definitions between a list of
wenzelm@54032
  2292
equations with patterns on the lhs and a single equation with case

expressions on the rhs. See also Ex/Simps_Case_Conv_Examples.thy.
wenzelm@54032
  2294
wenzelm@54032

  2296
sets defined by Lifting/Transfer.
wenzelm@54032

  2311
* HOL-Algebra: Discontinued theories ~~/src/HOL/Algebra/abstract and
wenzelm@53983
  2312
~~/src/HOL/Algebra/poly.  Existing theories should be based on
wenzelm@53983

* HOL-BNF:
wenzelm@54032
  2317
  - Various improvements to BNF-based (co)datatype package, including

* Spec_Check is a Quickcheck tool for Isabelle/ML.  The ML function
wenzelm@53971
  2340
"check_property" allows to check specifications of the form "ALL x y
wenzelm@53971

retains its use as snapshot of the main Simplifier context, using
wenzelm@51717
  2366
simpset_of and put_simpset on Proof.context.  INCOMPATIBILITY -- port
wenzelm@51717
  2367
old tools by making them depend on (ctxt : Proof.context) instead of
wenzelm@51717
  2368
(ss : simpset), then turn (simpset_of ctxt) into ctxt.
wenzelm@51717
  2369
wenzelm@53971
  2370
* Modifiers for classical wrappers (e.g. addWrapper, delWrapper)
wenzelm@53971
  2371
operate on Proof.context instead of claset, for uniformity with addIs,
wenzelm@53971
  2372
addEs, addDs etc. Note that claset_of and put_claset allow to manage
wenzelm@53971
  2373
clasets separately from the context.
wenzelm@53971
  2374
wenzelm@51717
  2375
* Discontinued obsolete ML antiquotations @{claset} and @{simpset}.
wenzelm@51717
  2376
INCOMPATIBILITY, use @{context} instead.
wenzelm@51717
  2377
wenzelm@53971
  2378
* Antiquotation @{theory_context A} is similar to @{theory A}, but
wenzelm@53971

"isabelle build" in Isabelle2013.  INCOMPATIBILITY.
wenzelm@51398

wenzelm@52054
  2387
* Discontinued obsolete isabelle-process options -f and -u (former

wenzelm@52550
  2392
wenzelm@52746

* Discontinued ISABELLE_DOC_FORMAT settings variable and historic
wenzelm@52746
  2394
document formats: dvi.gz, ps, ps.gz -- the default document format is
wenzelm@52746
  2395
always pdf.
wenzelm@52743
  2396
wenzelm@52053
  2397
* Isabelle settings variable ISABELLE_BUILD_JAVA_OPTIONS allows to
wenzelm@52053
  2398
specify global resources of the JVM process run by isabelle build.
wenzelm@52053
  2399
wenzelm@52116
  2400
* Toplevel executable $ISABELLE_HOME/bin/isabelle_scala_script allows
wenzelm@52116
  2401
to run Isabelle/Scala source files as standalone programs.
wenzelm@52116
  2402
wenzelm@52439
  2403
* Improved "isabelle keywords" tool (for old-style ProofGeneral
wenzelm@52439
  2404
keyword tables): use Isabelle/Scala operations, which inspect outer
wenzelm@52439
  2405
syntax without requiring to build sessions first.
wenzelm@52439
  2406
wenzelm@53971
  2407
* Sessions may be organized via 'chapter' specifications in the ROOT
wenzelm@53971
  2408
file, which determines a two-level hierarchy of browser info.  The old
wenzelm@53971
  2409
tree-like organization via implicit sub-session relation (with its
wenzelm@53971
  2410
tendency towards erratic fluctuation of URLs) has been discontinued.
wenzelm@53971
  2411
The default chapter is called "Unsorted".  Potential INCOMPATIBILITY

*** General ***
wenzelm@47967
  2420
wenzelm@50126
  2421
* Theorem status about oracles and unfinished/failed future proofs is
wenzelm@50126
  2422
no longer printed by default, since it is incompatible with
wenzelm@50126
  2423
incremental / parallel checking of the persistent document model.  ML
wenzelm@50126
  2424
function Thm.peek_status may be used to inspect a snapshot of the
wenzelm@50126
  2425
ongoing evaluation process.  Note that in batch mode --- notably
wenzelm@50126
  2426
isabelle build --- the system ensures that future proofs of all
wenzelm@50126
  2427
accessible theorems in the theory context are finished (as before).
wenzelm@50126
  2428
wenzelm@49699
  2429
* Configuration option show_markup controls direct inlining of markup
wenzelm@49699
  2430
into the printed representation of formal entities --- notably type
wenzelm@49699
  2431
and sort constraints.  This enables Prover IDE users to retrieve that
wenzelm@49699
  2432
information via tooltips in the output window, for example.
wenzelm@49699
  2433
wenzelm@48890
  2434
* Command 'ML_file' evaluates ML text from a file directly within the
wenzelm@48890
  2435
theory, without any predeclaration via 'uses' in the theory header.
wenzelm@48890
  2436
wenzelm@49243
  2437
* Old command 'use' command and corresponding keyword 'uses' in the
wenzelm@49243
  2438
theory header are legacy features and will be discontinued soon.
wenzelm@49243
  2439
Tools that load their additional source files may imitate the
wenzelm@49243
  2440
'ML_file' implementation, such that the system can take care of
wenzelm@49243
  2441
dependencies properly.
wenzelm@49243
  2442
wenzelm@47967
  2443
* Discontinued obsolete method fastsimp / tactic fast_simp_tac, which
wenzelm@47967
  2444
is called fastforce / fast_force_tac already since Isabelle2011-1.
wenzelm@47967
  2445
wenzelm@50110
  2446
* Updated and extended "isar-ref" and "implementation" manual, reduced
wenzelm@50110
  2447
remaining material in old "ref" manual.
wenzelm@48120
  2448
wenzelm@51050
  2449
* Improved support for auxiliary contexts that indicate block structure
wenzelm@51050
  2450
for specifications.  Nesting of "context fixes ... context assumes ..."
wenzelm@49841
  2451
and "class ... context ...".
wenzelm@49841
  2452
wenzelm@50772
  2453
* Attribute "consumes" allows a negative value as well, which is
wenzelm@50778
  2454
interpreted relatively to the total number of premises of the rule in
wenzelm@50772
  2455
the target context.  This form of declaration is stable when exported
wenzelm@50772
  2456
from a nested 'context' with additional assumptions.  It is the
wenzelm@50772
  2457
preferred form for definitional packages, notably cases/rules produced
wenzelm@50772
  2458
in HOL/inductive and HOL/function.
wenzelm@50772
  2459
wenzelm@49869
  2460
* More informative error messages for Isar proof commands involving
wenzelm@49869
  2461
lazy enumerations (method applications etc.).
wenzelm@49869
  2462
wenzelm@50213
  2463
* Refined 'help' command to retrieve outer syntax commands according
wenzelm@50213
  2464
to name patterns (with clickable results).

  2467
*** Prover IDE -- Isabelle/Scala/jEdit ***
wenzelm@49968
  2468
wenzelm@49968
  2469
* Parallel terminal proofs ('by') are enabled by default, likewise
wenzelm@49968
  2470
proofs that are built into packages like 'datatype', 'function'.  This
wenzelm@49968
  2471
allows to "run ahead" checking the theory specifications on the
wenzelm@49968
  2472
surface, while the prover is still crunching on internal
wenzelm@49968
  2473
justifications.  Unfinished / cancelled proofs are restarted as
wenzelm@49968
  2474
required to complete full proof checking eventually.
wenzelm@49968
  2475
wenzelm@49968
  2476
* Improved output panel with tooltips, hyperlinks etc. based on the
wenzelm@49968
  2477
same Rich_Text_Area as regular Isabelle/jEdit buffers.  Activation of
wenzelm@49968
  2478
tooltips leads to some window that supports the same recursively,
wenzelm@49968
  2479
which can lead to stacks of tooltips as the semantic document content
wenzelm@49968
  2480
is explored.  ESCAPE closes the whole stack, individual windows may be
wenzelm@49968
  2481
closed separately, or detached to become independent jEdit dockables.
wenzelm@49968
  2482
wenzelm@50717
  2483
* Improved support for commands that produce graph output: the text
wenzelm@50717
  2484
message contains a clickable area to open a new instance of the graph
wenzelm@50717
  2485
browser on demand.
wenzelm@50717
  2486
wenzelm@49968
  2487
* More robust incremental parsing of outer syntax (partial comments,
wenzelm@49968
  2488
malformed symbols).  Changing the balance of open/close quotes and
wenzelm@49968
  2489
comment delimiters works more conveniently with unfinished situations
wenzelm@49968
  2490
that frequently occur in user interaction.
wenzelm@49968
  2491
wenzelm@49968
  2492
* More efficient painting and improved reactivity when editing large
wenzelm@49968
  2493
files.  More scalable management of formal document content.
wenzelm@49968
  2494
wenzelm@50505
  2495
* Smarter handling of tracing messages: prover process pauses after
wenzelm@50505
  2496
certain number of messages per command transaction, with some user
wenzelm@50505
  2497
dialog to stop or continue.  This avoids swamping the front-end with
wenzelm@50119
  2498
potentially infinite message streams.
wenzelm@49968
  2499
wenzelm@49968
  2500
* More plugin options and preferences, based on Isabelle/Scala.  The
wenzelm@49968
  2501
jEdit plugin option panel provides access to some Isabelle/Scala
wenzelm@49968
  2502
options, including tuning parameters for editor reactivity and color
wenzelm@49968
  2503
schemes.
wenzelm@49968
  2504
wenzelm@50184
  2505
* Dockable window "Symbols" provides some editing support for Isabelle
wenzelm@50184
  2506
symbols.
wenzelm@50184
  2507
wenzelm@51082
  2508
* Dockable window "Monitor" shows ML runtime statistics.  Note that
wenzelm@51082
  2509
continuous display of the chart slows down the system.
wenzelm@50701
  2510
wenzelm@50183
  2511
* Improved editing support for control styles: subscript, superscript,
wenzelm@50183
  2512
bold, reset of style -- operating on single symbols or text
wenzelm@50198
  2513
selections.  Cf. keyboard shortcuts C+e DOWN/UP/RIGHT/LEFT.
wenzelm@50198
  2514
wenzelm@50198
  2515
* Actions isabelle.increase-font-size and isabelle.decrease-font-size
wenzelm@50198
  2516
adjust the main text area font size, and its derivatives for output,
wenzelm@50836
  2517
tooltips etc.  Cf. keyboard shortcuts C-PLUS and C-MINUS, which often
wenzelm@50836
  2518
need to be adapted to local keyboard layouts.
wenzelm@50183
  2519
wenzelm@50730
  2520
* More reactive completion popup by default: use \t (TAB) instead of
wenzelm@50730
  2521
\n (NEWLINE) to minimize intrusion into regular flow of editing.  See
wenzelm@50730
  2522
also "Plugin Options / SideKick / General / Code Completion Options".
wenzelm@50730
  2523
wenzelm@50406
  2524
* Implicit check and build dialog of the specified logic session
wenzelm@50406
  2525
image.  For example, HOL, HOLCF, HOL-Nominal can be produced on
wenzelm@50406
  2526
demand, without bundling big platform-dependent heap images in the
wenzelm@50406
  2527
Isabelle distribution.
wenzelm@50406
  2528
wenzelm@49968
  2529
* Uniform Java 7 platform on Linux, Mac OS X, Windows: recent updates
wenzelm@49968
  2530
from Oracle provide better multi-platform experience.  This version is
wenzelm@49968
  2531
now bundled exclusively with Isabelle.

haftmann@48431
  2537
Haskell Prelude to a small set of fundamental operations.
haftmann@48431
  2538
wenzelm@50646
  2539
* Command 'export_code': relative file names are interpreted
wenzelm@50646
  2540
relatively to master directory of current theory rather than the
wenzelm@50646
  2541
rather arbitrary current working directory.  INCOMPATIBILITY.
haftmann@48371
  2542
wenzelm@48205
  2543
* Discontinued obsolete attribute "COMP".  Potential INCOMPATIBILITY,
wenzelm@48205
  2544
use regular rule composition via "OF" / "THEN", or explicit proof
wenzelm@48205
  2545
structure instead.  Note that Isabelle/ML provides a variety of
wenzelm@48205
  2546
operators like COMP, INCR_COMP, COMP_INCR, which need to be applied
wenzelm@48205
  2547
with some care where this is really required.
wenzelm@48205
  2548
wenzelm@48792
  2549
* Command 'typ' supports an additional variant with explicit sort
wenzelm@48792
  2550
constraint, to infer and check the most general type conforming to a
wenzelm@51063
  2551
given sort.  Example (in HOL):
wenzelm@48792
  2552
wenzelm@48792
  2553
  typ "_ * _ * bool * unit" :: finite
wenzelm@48792
  2554
wenzelm@50716

* Command 'locale_deps' visualizes all locales and their relations as
wenzelm@50716

wenzelm@50646
  2563
  - Added MaSh relevance filter based on machine-learning; see the

  - Polished Isar proofs generated with "isar_proofs" option.
wenzelm@50646
  2566
  - Rationalized type encodings ("type_enc" option).
blanchet@50720
  2567
  - Renamed "kill_provers" subcommand to "kill_all".
wenzelm@50646

wenzelm@50646
  2588
wenzelm@50646

  2590
pointfree expressions.
wenzelm@50646

wenzelm@50646
  2592
* The SMT solver Z3 has now by default a restricted set of directly
wenzelm@50646
  2593
supported features. For the full set of features (div/mod, nonlinear
wenzelm@50646
  2594
arithmetic, datatypes/records) with potential proof reconstruction
wenzelm@50646
  2595
failures, enable the configuration option "z3_with_extensions".  Minor
wenzelm@50646
  2596
INCOMPATIBILITY.
haftmann@49948
  2597
wenzelm@49836
  2598
* Simplified 'typedef' specifications: historical options for implicit
wenzelm@49836
  2599
set definition and alternative name have been discontinued.  The
wenzelm@49836
  2600
former behavior of "typedef (open) t = A" is now the default, but
wenzelm@49836

haftmann@49388
  2614
wenzelm@50646
  2615
* Added combinator "Option.these" with type "'a option set => 'a set".
wenzelm@50646

  2631
* Generalized the definition of limits:
wenzelm@50646
  2632
wenzelm@50646
  2633
  - Introduced the predicate filterlim (LIM x F. f x :> G) which
wenzelm@50646
  2634
    expresses that when the input values x converge to F then the
wenzelm@50646
  2635
    output f x converges to G.
wenzelm@50646
  2636
wenzelm@50646
  2637
  - Added filters for convergence to positive (at_top) and negative
wenzelm@50646
  2638
    infinity (at_bot).
wenzelm@50646
  2639
wenzelm@50646
  2640
  - Moved infinity in the norm (at_infinity) from
wenzelm@50646
  2641
    Multivariate_Analysis to Complex_Main.
wenzelm@50646
  2642
wenzelm@50646
  2643
  - Removed real_tendsto_inf, it is superseded by "LIM x F. f x :>

* Renamed theory Library/List_Prefix to Library/Sublist, with related
wenzelm@50646
  2659
changes as follows.
wenzelm@50646
  2660
wenzelm@50646
  2661
  - Renamed constants (and related lemmas)
Christian@49145
  2662
Christian@49145
  2663
      prefix ~> prefixeq
Christian@49145
  2664
      strict_prefix ~> prefix
Christian@49145
  2665
wenzelm@50646
  2666
  - Replaced constant "postfix" by "suffixeq" with swapped argument
wenzelm@50646
  2667
    order (i.e., "postfix xs ys" is now "suffixeq ys xs") and dropped
wenzelm@50646
  2668
    old infix syntax "xs >>= ys"; use "suffixeq ys xs" instead.
wenzelm@50646
  2669
    Renamed lemmas accordingly.
wenzelm@50646
  2670
wenzelm@50646
  2671
  - Added constant "list_hembeq" for homeomorphic embedding on
wenzelm@50646
  2672
    lists. Added abbreviation "sublisteq" for special case
wenzelm@50646
  2673
    "list_hembeq (op =)".
wenzelm@50646
  2674
wenzelm@50646
  2675
  - Theory Library/Sublist no longer provides "order" and "bot" type
wenzelm@50646
  2676
    class instances for the prefix order (merely corresponding locale
wenzelm@50646
  2677
    interpretations). The type class instances are now in theory
wenzelm@50646
  2678
    Library/Prefix_Order.
wenzelm@50646
  2679
wenzelm@50646
  2680
  - The sublist relation of theory Library/Sublist_Order is now based
wenzelm@50646
  2681
    on "Sublist.sublisteq".  Renamed lemmas accordingly:
Christian@50516
