*** Prover IDE -- Isabelle/Scala/jEdit ***
wenzelm@60610
    11
wenzelm@60610
    12
* Improved scheduling for urgent print tasks (e.g. command state output,
wenzelm@60610
    13
interactive queries) wrt. long-running background tasks.
wenzelm@60610
    14
wenzelm@60986
    15
* IDE support for the source-level debugger of Poly/ML, to work with
wenzelm@60984
    16
Isabelle/ML and official Standard ML. Configuration option "ML_debugger"
wenzelm@60984
    17
and commands 'ML_file_debug', 'ML_file_no_debug', 'SML_file_debug',
wenzelm@60984
    18
'SML_file_no_debug' control compilation of sources with debugging
wenzelm@60984
    19
information. The Debugger panel allows to set breakpoints (via context
wenzelm@60984
    20
menu), step through stopped threads, evaluate local ML expressions etc.
wenzelm@60984
    21
At least one Debugger view needs to be active to have any effect on the
wenzelm@60984
    22
running ML program.

*** Isar ***
wenzelm@60406
    26
wenzelm@60406
    27
* Command 'obtain' binds term abbreviations (via 'is' patterns) in the
wenzelm@60406
    28
proof body as well, abstracted over relevant parameters.
wenzelm@60406
    29
wenzelm@60477
    30
* Improved type-inference for theorem statement 'obtains': separate
wenzelm@60477
    31
parameter scope for of each clause.
wenzelm@60477
    32
wenzelm@60408
    33
* Term abbreviations via 'is' patterns also work for schematic
wenzelm@60408
    34
statements: result is abstracted over unknowns.
wenzelm@60408
    35
wenzelm@60414
    36
* Local goals ('have', 'show', 'hence', 'thus') allow structured
wenzelm@60414
    37
statements like fixes/assumes/shows in theorem specifications, but the
wenzelm@60555
    38
notation is postfix with keywords 'if' (or 'when') and 'for'. For
wenzelm@60555
    39
example:
wenzelm@60414
    40
wenzelm@60414
    41
  have result: "C x y"
wenzelm@60414
    42
    if "A x" and "B y"
wenzelm@60414
    43
    for x :: 'a and y :: 'a
wenzelm@60414
    44
    <proof>
wenzelm@60414
    45
wenzelm@60449
    46
The local assumptions are bound to the name "that". The result is
wenzelm@60449
    47
exported from context of the statement as usual. The above roughly
wenzelm@60414
    48
corresponds to a raw proof block like this:
wenzelm@60414
    49
wenzelm@60414
    50
  {
wenzelm@60414
    51
    fix x :: 'a and y :: 'a
wenzelm@60449
    52
    assume that: "A x" "B y"
wenzelm@60414
    53
    have "C x y" <proof>
wenzelm@60414
    54
  }
wenzelm@60414
    55
  note result = this
wenzelm@60406
    56
wenzelm@60555
    57
The keyword 'when' may be used instead of 'if', to indicate 'presume'
wenzelm@60555
    58
instead of 'assume' above.
wenzelm@60555
    59
wenzelm@60595
    60
* The meaning of 'show' with Pure rule statements has changed: premises
wenzelm@60595
    61
are treated in the sense of 'assume', instead of 'presume'. This means,
wenzelm@60595
    62
a goal like "\<And>x. A x \<Longrightarrow> B x \<Longrightarrow> C x" can be solved completely as follows:
wenzelm@60595
    63
wenzelm@60595
    64
  show "\<And>x. A x \<Longrightarrow> B x \<Longrightarrow> C x"
wenzelm@60595
    65
wenzelm@60595
    66
or:
wenzelm@60595
    67
wenzelm@60595
    68
  show "C x" if "A x" "B x" for x
wenzelm@60595
    69
wenzelm@60595
    70
Rare INCOMPATIBILITY, the old behaviour may be recovered as follows:
wenzelm@60595
    71
wenzelm@60595
    72
  show "C x" when "A x" "B x" for x
wenzelm@60595
    73
wenzelm@60406
    74
* New command 'supply' supports fact definitions during goal refinement
wenzelm@60406
    75
('apply' scripts).
wenzelm@60406
    76
wenzelm@60459
    77
* New command 'consider' states rules for generalized elimination and
wenzelm@60459
    78
case splitting. This is like a toplevel statement "theorem obtains" used
wenzelm@60459
    79
within a proof body; or like a multi-branch 'obtain' without activation
wenzelm@60459
    80
of the local context elements yet.
wenzelm@60459
    81
wenzelm@60455
    82
* Proof method "cases" allows to specify the rule as first entry of
wenzelm@60455
    83
chained facts.  This is particularly useful with 'consider':
wenzelm@60455
    84
wenzelm@60455
    85
  consider (a) A | (b) B | (c) C <proof>
wenzelm@60455
    86
  then have something
wenzelm@60455
    87
  proof cases
wenzelm@60455
    88
    case a
wenzelm@60455
    89
    then show ?thesis <proof>
wenzelm@60455
    90
  next
wenzelm@60455
    91
    case b
wenzelm@60455
    92
    then show ?thesis <proof>
wenzelm@60455
    93
  next
wenzelm@60455
    94
    case c
wenzelm@60455
    95
    then show ?thesis <proof>
wenzelm@60455
    96
  qed
wenzelm@60455
    97
wenzelm@60565
    98
* Command 'case' allows fact name and attribute specification like this:
wenzelm@60565
    99
wenzelm@60565
   100
  case a: (c xs)
wenzelm@60565
   101
  case a [attributes]: (c xs)
wenzelm@60565
   102
wenzelm@60565
   103
Facts that are introduced by invoking the case context are uniformly
wenzelm@60565
   104
qualified by "a"; the same name is used for the cumulative fact. The old
wenzelm@60565
   105
form "case (c xs) [attributes]" is no longer supported. Rare
wenzelm@60565
   106
INCOMPATIBILITY, need to adapt uses of case facts in exotic situations,
wenzelm@60565
   107
and always put attributes in front.
wenzelm@60565
   108
wenzelm@60618
   109
* The standard proof method of commands 'proof' and '..' is now called
wenzelm@60618
   110
"standard" to make semantically clear what it is; the old name "default"
wenzelm@60618
   111
is still available as legacy for some time. Documentation now explains
wenzelm@60618
   112
'..' more accurately as "by standard" instead of "by rule".
wenzelm@60618
   113
wenzelm@60631
   114
* Command 'subgoal' allows to impose some structure on backward
wenzelm@60631
   115
refinements, to avoid proof scripts degenerating into long of 'apply'
wenzelm@60631
   116
sequences. Further explanations and examples are given in the isar-ref
wenzelm@60631
   117
manual.
wenzelm@60631
   118
wenzelm@60578
   119
* Proof method "goals" turns the current subgoals into cases within the
wenzelm@60578
   120
context; the conclusion is bound to variable ?case in each case.
wenzelm@60617
   121
For example:
wenzelm@60617
   122
wenzelm@60617
   123
lemma "\<And>x. A x \<Longrightarrow> B x \<Longrightarrow> C x"
wenzelm@60622
   124
  and "\<And>y z. U y \<Longrightarrow> V z \<Longrightarrow> W y z"
wenzelm@60622
   125
proof goals
wenzelm@60622
   126
  case (1 x)
wenzelm@60622
   127
  then show ?case using \<open>A x\<close> \<open>B x\<close> sorry
wenzelm@60622
   128
next
wenzelm@60622
   129
  case (2 y z)
wenzelm@60622
   130
  then show ?case using \<open>U y\<close> \<open>V z\<close> sorry
wenzelm@60622
   131
qed
wenzelm@60622
   132
wenzelm@60622
   133
lemma "\<And>x. A x \<Longrightarrow> B x \<Longrightarrow> C x"
wenzelm@60622
   134
  and "\<And>y z. U y \<Longrightarrow> V z \<Longrightarrow> W y z"
wenzelm@60617
   135
proof goals
wenzelm@60617
   136
  case prems: 1
wenzelm@60617
   137
  then show ?case using prems sorry
wenzelm@60617
   138
next
wenzelm@60617
   139
  case prems: 2
wenzelm@60617
   140
  then show ?case using prems sorry
wenzelm@60617
   141
qed
wenzelm@60578
   142
wenzelm@60581
   143
* The undocumented feature of implicit cases goal1, goal2, goal3, etc.
wenzelm@60617
   144
is marked as legacy, and will be removed eventually. The proof method
wenzelm@60617
   145
"goals" achieves a similar effect within regular Isar; often it can be
wenzelm@60617
   146
done more adequately by other means (e.g. 'consider').
wenzelm@60581
   147
wenzelm@60551
   148
* Nesting of Isar goal structure has been clarified: the context after
wenzelm@60551
   149
the initial backwards refinement is retained for the whole proof, within
wenzelm@60551
   150
all its context sections (as indicated via 'next'). This is e.g.
wenzelm@60551
   151
relevant for 'using', 'including', 'supply':
wenzelm@60551
   152
wenzelm@60551
   153
  have "A \<and> A" if a: A for A
wenzelm@60551
   154
    supply [simp] = a
wenzelm@60551
   155
  proof
wenzelm@60551
   156
    show A by simp
wenzelm@60551
   157
  next
wenzelm@60551
   158
    show A by simp
wenzelm@60551
   159
  qed
wenzelm@60551
   160
wenzelm@60554
   161
* Method "sleep" succeeds after a real-time delay (in seconds). This is
wenzelm@60554
   162
occasionally useful for demonstration and testing purposes.
wenzelm@60554
   163
wenzelm@60406
   164
wenzelm@60331
   165
*** Pure ***
wenzelm@60331
   166
wenzelm@60489
   167
* The vacuous fact "TERM x" may be established "by fact" or as `TERM x`
wenzelm@60489
   168
as well, not just "by this" or "." as before.
wenzelm@60489
   169
wenzelm@60331
   170
* Configuration option rule_insts_schematic has been discontinued
wenzelm@60331
   171
(intermediate legacy feature in Isabelle2015).  INCOMPATIBILITY.
wenzelm@60331
   172
haftmann@60349
   173
* Abbreviations in type classes now carry proper sort constraint.
haftmann@60349
   174
Rare INCOMPATIBILITY in situations where the previous misbehaviour
haftmann@60349
   175
has been exploited previously.
haftmann@60349
   176
haftmann@60349
   177
* Refinement of user-space type system in type classes: pseudo-local
haftmann@60349
   178
operations behave more similar to abbreviations.  Potential
haftmann@60349
   179
INCOMPATIBILITY in exotic situations.
haftmann@60349
   180
haftmann@60349
   181
nipkow@60171
   182
*** HOL ***
nipkow@60171
   183
wenzelm@61118
   184
* Qualification of various formal entities in the libraries is done more
wenzelm@61118
   185
uniformly via "context begin qualified definition ... end" instead of
wenzelm@61118
   186
old-style "hide_const (open) ...". Consequently, both the defined
wenzelm@61118
   187
constant and its defining fact become qualified, e.g. Option.is_none and
wenzelm@61118
   188
Option.is_none_def. Occasional INCOMPATIBILITY in applications.
wenzelm@61118
   189
wenzelm@61069
   190
* Some old and rarely used ASCII replacement syntax has been removed.
wenzelm@61069
   191
INCOMPATIBILITY, standard syntax with symbols should be used instead.
wenzelm@61069
   192
The subsequent commands help to reproduce the old forms, e.g. to
wenzelm@61069
   193
simplify porting old theories:
wenzelm@61069
   194
wenzelm@61069
   195
  type_notation Map.map  (infixr "~=>" 0)
wenzelm@61069
   196
  notation Map.map_comp  (infixl "o'_m" 55)
wenzelm@61069
   197
wenzelm@60841
   198
* Theory Map: lemma map_of_is_SomeD was a clone of map_of_SomeD and has
wenzelm@60841
   199
been removed. INCOMPATIBILITY.
wenzelm@60841
   200
lars@60712
   201
* Quickcheck setup for finite sets.
lars@60712
   202
nipkow@60171
   203
* Discontinued simp_legacy_precond. Potential INCOMPATIBILITY.
wenzelm@60138
   204
blanchet@60306
   205
* Sledgehammer:
blanchet@60306
   206
  - Proof reconstruction has been improved, to minimize the incidence of
blanchet@60306
   207
    cases where Sledgehammer gives a proof that does not work.
blanchet@60306
   208
  - Auto Sledgehammer now minimizes and preplays the results.
blanchet@61030
   209
  - Handle Vampire 4.0 proof output without raising exception.
blanchet@61043
   210
  - Eliminated "MASH" environment variable. Use the "MaSh" option in
blanchet@61043
   211
    Isabelle/jEdit instead. INCOMPATIBILITY.
blanchet@60306
   212
blanchet@60310
   213
* Nitpick:
blanchet@60310
   214
  - Removed "check_potential" and "check_genuine" options.
blanchet@60310
   215
traytel@60922
   216
* New commands lift_bnf and copy_bnf for lifting (copying) a BNF structure
traytel@60922
   217
  on the raw type to an abstract type defined using typedef.
traytel@60920
   218
haftmann@60868
   219
* Division on integers is bootstrapped directly from division on
haftmann@60868
   220
naturals and uses generic numeral algorithm for computations.
haftmann@60868
   221
Slight INCOMPATIBILITY, simproc numeral_divmod replaces and generalizes
haftmann@60868
   222
former simprocs binary_int_div and binary_int_mod
haftmann@60868
   223
haftmann@60516
   224
* Tightened specification of class semiring_no_zero_divisors.  Slight
haftmann@60516
   225
INCOMPATIBILITY.
haftmann@60516
   226
haftmann@60688
   227
* Class algebraic_semidom introduces common algebraic notions of
haftmann@60688
   228
integral (semi)domains, particularly units.  Although
haftmann@60517
   229
logically subsumed by fields, is is not a super class of these
haftmann@60517
   230
in order not to burden fields with notions that are trivial there.
haftmann@60688
   231
haftmann@60688
   232
* Class normalization_semidom specifies canonical representants
haftmann@60688
   233
for equivalence classes of associated elements in an integral
haftmann@60688
   234
(semi)domain.  This formalizes associated elements as well.
haftmann@60688
   235
haftmann@60688
   236
* Abstract specification of gcd/lcm operations in classes semiring_gcd,
haftmann@60688
   237
semiring_Gcd, semiring_Lcd.  Minor INCOMPATIBILITY: facts gcd_nat.commute
haftmann@60688
   238
and gcd_int.commute are subsumed by gcd.commute, as well as gcd_nat.assoc
haftmann@60688
   239
and gcd_int.assoc by gcd.assoc.
haftmann@60517
   240
haftmann@60429
   241
* Former constants Fields.divide (_ / _) and Divides.div (_ div _)
haftmann@60354
   242
are logically unified to Rings.divide in syntactic type class
haftmann@60429
   243
Rings.divide, with infix syntax (_ div _).  Infix syntax (_ / _)
haftmann@60429
   244
for field division is added later as abbreviation in class Fields.inverse.
haftmann@60516
   245
INCOMPATIBILITY,  instantiations must refer to Rings.divide rather
haftmann@60429
   246
than the former separate constants, hence infix syntax (_ / _) is usually
haftmann@60429
   247
not available during instantiation.
haftmann@60354
   248
Mathias@60397
   249
* Library/Multiset:
Mathias@60397
   250
  - Renamed multiset inclusion operators:
Mathias@60397
   251
      < ~> <#
Mathias@60397
   252
      \<subset> ~> \<subset>#
Mathias@60397
   253
      <= ~> <=#
Mathias@60397
   254
      \<le> ~> \<le>#
Mathias@60397
   255
      \<subseteq> ~> \<subseteq>#
Mathias@60397
   256
    INCOMPATIBILITY.
Mathias@60397
   257
  - "'a multiset" is no longer an instance of the "order",
Mathias@60397
   258
    "ordered_ab_semigroup_add_imp_le", "ordered_cancel_comm_monoid_diff",
Mathias@60397
   259
    "semilattice_inf", and "semilattice_sup" type classes. The theorems
Mathias@60397
   260
    previously provided by these type classes (directly or indirectly)
Mathias@60397
   261
    are now available through the "subset_mset" interpretation
Mathias@60397
   262
    (e.g. add_mono ~> subset_mset.add_mono).
Mathias@60397
   263
    INCOMPATIBILITY.
nipkow@60497
   264
  - Renamed conversions:
nipkow@60515
   265
      multiset_of ~> mset
nipkow@60515
   266
      multiset_of_set ~> mset_set
nipkow@60497
   267
      set_of ~> set_mset
nipkow@60497
   268
    INCOMPATIBILITY
Mathias@60398
   269
  - Renamed lemmas:
Mathias@60398
   270
      mset_le_def ~> subseteq_mset_def
Mathias@60398
   271
      mset_less_def ~> subset_mset_def
Mathias@60400
   272
      less_eq_multiset.rep_eq ~> subseteq_mset_def
Mathias@60400

wenzelm@60642

wenzelm@60642
   313
wenzelm@60707

* Subgoal.SUBPROOF and Subgoal.FOCUS combinators use anonymous
wenzelm@60707
   315
quasi-bound variables (like the Simplifier), instead of accidentally
wenzelm@60707
   316
named local fixes. This has the potential to improve stability of proof
wenzelm@60707

wenzelm@59939
   336
* Local theory specification commands may have a 'private' or
wenzelm@59990
   337
'qualified' modifier to restrict name space accesses to the local scope,
wenzelm@59939
   338
as provided by some "context begin ... end" block. For example:

   355
naming policy.
wenzelm@59901
   356
wenzelm@59951
   357
* Command 'notepad' requires proper nesting of begin/end and its proof
wenzelm@59951
   358
structure in the body: 'oops' is no longer supported here. Minor
wenzelm@59951
   359
INCOMPATIBILITY, use 'sorry' instead.
wenzelm@59951
   360
wenzelm@59951
   361
* Command 'named_theorems' declares a dynamic fact within the context,
wenzelm@59951
   362
together with an attribute to maintain the content incrementally. This
wenzelm@59951
   363
supersedes functor Named_Thms in Isabelle/ML, but with a subtle change
wenzelm@59951
   364
of semantics due to external visual order vs. internal reverse order.
wenzelm@59951
   365
wenzelm@59951
   366
* 'find_theorems': search patterns which are abstractions are
wenzelm@59951

INCOMPATIBILITY.
wenzelm@59648

wenzelm@59569

wenzelm@57941
   373
wenzelm@58928
   374
* Outer syntax commands are managed authentically within the theory
wenzelm@59569
   375

wenzelm@58928
   376
INCOMPATIBILITY, make sure that required theories are really imported.
wenzelm@58928
   377
wenzelm@60116
   378
* Historical command-line terminator ";" is no longer accepted (and
wenzelm@60116
   379
already used differently in Isar). Minor INCOMPATIBILITY, use "isabelle
wenzelm@60116
   380

wenzelm@60116
   381

wenzelm@60116

wenzelm@59951
   383
* Structural composition of proof methods (meth1; meth2) in Isar

haftmann@59105
   385
wenzelm@60119
   386
* The Eisbach proof method language allows to define new proof methods
wenzelm@60119
   387
by combining existing ones with their usual syntax. The "match" proof
wenzelm@60119
   388
method provides basic fact/term matching in addition to
wenzelm@60119
   389
premise/conclusion matching through Subgoal.focus, and binds fact names
wenzelm@60288
   390
from matches as well as term patterns within matches. The Isabelle
wenzelm@60288
   391
documentation provides an entry "eisbach" for the Eisbach User Manual.

wenzelm@58540
   404

wenzelm@58540
   405
marker, SideKick parser.
wenzelm@58524
   406
wenzelm@58551
   407
* Document antiquotation @{cite} provides formal markup, which is
wenzelm@60265
   408
interpreted semi-formally based on .bib files that happen to be open in
wenzelm@60265
   409
the editor (hyperlinks, completion etc.).
wenzelm@58551
   410
wenzelm@58785

wenzelm@58785
   413
wenzelm@60091
   414
* Improved graphview panel with optional output of PNG or PDF, for
wenzelm@60273
   415
display of 'thy_deps', 'class_deps' etc.
wenzelm@60010
   416
wenzelm@60116
   417
* The commands 'thy_deps' and 'class_deps' allow optional bounds to
wenzelm@60116
   418
restrict the visualized hierarchy.
wenzelm@60095
   419
wenzelm@60072
   420
* Improved scheduling for asynchronous print commands (e.g. provers
wenzelm@60072

*** Document preparation ***
wenzelm@59951
   425
wenzelm@59951
   426
* Document markup commands 'chapter', 'section', 'subsection',
wenzelm@59951
   427
'subsubsection', 'text', 'txt', 'text_raw' work uniformly in any
wenzelm@59951
   428
context, even before the initial 'theory' command. Obsolete proof
wenzelm@59951
   429
commands 'sect', 'subsect', 'subsubsect', 'txt_raw' have been
wenzelm@59951
   430
discontinued, use 'section', 'subsection', 'subsubsection', 'text_raw'
wenzelm@59951
   431
instead. The old 'header' command is still retained for some time, but
wenzelm@59951
   432
should be replaced by 'chapter', 'section' etc. (using "isabelle
wenzelm@59951
   433
update_header"). Minor INCOMPATIBILITY.
wenzelm@59951
   434
wenzelm@60010
   435
* Official support for "tt" style variants, via \isatt{...} or
wenzelm@60010
   436
\begin{isabellett}...\end{isabellett}. The somewhat fragile \verb or
wenzelm@60010
   437
verbatim environment of LaTeX is no longer used. This allows @{ML} etc.
wenzelm@60010
   438
as argument to other macros (such as footnotes).
wenzelm@60010
   439
wenzelm@60010
   440
* Document antiquotation @{verbatim} prints ASCII text literally in "tt"
wenzelm@60010
   441
style.
wenzelm@60010
   442
wenzelm@60010
   443
* Discontinued obsolete option "document_graph": session_graph.pdf is
wenzelm@60010
   444
produced unconditionally for HTML browser_info and PDF-LaTeX document.
wenzelm@60010
   445
wenzelm@59951
   446
* Diagnostic commands and document markup commands within a proof do not
wenzelm@59951
   447
affect the command tag for output. Thus commands like 'thm' are subject
wenzelm@59951
   448
to proof document structure, and no longer "stick out" accidentally.
wenzelm@59951
   449
Commands 'text' and 'txt' merely differ in the LaTeX style, not their
wenzelm@59951
   450
tags. Potential INCOMPATIBILITY in exotic situations.
wenzelm@59951
   451
wenzelm@59951
   452
* System option "pretty_margin" is superseded by "thy_output_margin",
wenzelm@59951
   453
which is also accessible via document antiquotation option "margin".
wenzelm@59951
   454
Only the margin for document output may be changed, but not the global
wenzelm@59951
   455
pretty printing: that is 76 for plain console output, and adapted
wenzelm@59951
   456
dynamically in GUI front-ends. Implementations of document
wenzelm@59951
   457
antiquotations need to observe the margin explicitly according to
wenzelm@59951
   458
Thy_Output.string_of_margin. Minor INCOMPATIBILITY.
wenzelm@59951
   459
wenzelm@60299
   460
* Specification of 'document_files' in the session ROOT file is
wenzelm@60299
   461
mandatory for document preparation. The legacy mode with implicit
wenzelm@60299
   462
copying of the document/ directory is no longer supported. Minor

wenzelm@59835
   468
* Proof methods with explicit instantiation ("rule_tac", "subgoal_tac"
wenzelm@59835
   469
etc.) allow an optional context of local variables ('for' declaration):
wenzelm@59835
   470
these variables become schematic in the instantiated theorem; this
wenzelm@59835
   471
behaviour is analogous to 'for' in attributes "where" and "of".
wenzelm@59835
   472
Configuration option rule_insts_schematic (default false) controls use
wenzelm@59835
   473
of schematic variables outside the context. Minor INCOMPATIBILITY,
wenzelm@59835
   474
declare rule_insts_schematic = true temporarily and update to use local
wenzelm@59835
   475
variable declarations or dummy patterns instead.
wenzelm@59835
   476
wenzelm@60010
   477
* Explicit instantiation via attributes "where", "of", and proof methods
wenzelm@60010
   478
"rule_tac" with derivatives like "subgoal_tac" etc. admit dummy patterns
wenzelm@60010
   479
("_") that stand for anonymous local variables.
wenzelm@60010
   480
wenzelm@59951
   481
* Generated schematic variables in standard format of exported facts are
wenzelm@59951
   482
incremented to avoid material in the proof context. Rare
wenzelm@59951
   483
INCOMPATIBILITY, explicit instantiation sometimes needs to refer to
wenzelm@59951
   484
different index.
wenzelm@59951
   485
wenzelm@60011
   486
* Lexical separation of signed and unsigned numerals: categories "num"
wenzelm@60011
   487
and "float" are unsigned. INCOMPATIBILITY: subtle change in precedence
wenzelm@60011
   488
of numeral signs, particularly in expressions involving infix syntax
wenzelm@60011
   489
like "(- 1) ^ n".
haftmann@58410
   490
wenzelm@58421
   491
* Old inner token category "xnum" has been discontinued.  Potential
wenzelm@58421
   492
INCOMPATIBILITY for exotic syntax: may use mixfix grammar with "num"
wenzelm@58421
   493
token category instead.

wenzelm@60115
   547
    Minor INCOMPATIBILITY: (rarely used by name) transfer theorem names
wenzelm@60115
   548
    changed (e.g. map_prod_transfer ~> prod.map_transfer).
wenzelm@60261
   549
  - Parametricity theorems for map functions, relators, set functions,
wenzelm@60261
   550
    constructors, case combinators, discriminators, selectors and
wenzelm@60261
   551
    (co)recursors are automatically proved and registered as transfer
wenzelm@60261
   552
    rules.

* Old datatype package:
blanchet@58310
   555
  - The old 'datatype' command has been renamed 'old_datatype', and
blanchet@58374
   556
    'rep_datatype' has been renamed 'old_rep_datatype'. They are
blanchet@58374
   557
    provided by "~~/src/HOL/Library/Old_Datatype.thy". See

      weak_case_cong ~> case_cong_weak
blanchet@57983
   562
    INCOMPATIBILITY.
blanchet@58374
   563
  - Renamed theory:
blanchet@58374
   564
      ~~/src/HOL/Datatype.thy ~> ~~/src/HOL/Library/Old_Datatype.thy
blanchet@58374
   565
    INCOMPATIBILITY.
blanchet@57983
   566
blanchet@59039
   567
* Nitpick:
wenzelm@60011
   568
  - Fixed soundness bug related to the strict and non-strict subset
blanchet@59039
   569
    operations.
blanchet@59039
   570
blanchet@57737
   571
* Sledgehammer:
blanchet@59511
   572
  - CVC4 is now included with Isabelle instead of CVC3 and run by
blanchet@59511
   573
    default.
blanchet@59965
   574
  - Z3 is now always enabled by default, now that it is fully open
blanchet@59965
   575
    source. The "z3_non_commercial" option is discontinued.
blanchet@57737
   576
  - Minimization is now always enabled by default.
wenzelm@60011
   577
    Removed sub-command:
blanchet@57737
   578
      min
blanchet@59967
   579
  - Proof reconstruction, both one-liners and Isar, has been
blanchet@59039
   580
    dramatically improved.
blanchet@59039
   581
  - Improved support for CVC4 and veriT.
blanchet@57737
   582
blanchet@58062
   583
* Old and new SMT modules:
blanchet@58067
   584
  - The old 'smt' method has been renamed 'old_smt' and moved to
wenzelm@59569
   585
    'src/HOL/Library/Old_SMT.thy'. It is provided for compatibility,
wenzelm@59569
   586
    until applications have been ported to use the new 'smt' method. For
wenzelm@59569
   587
    the method to work, an older version of Z3 (e.g. Z3 3.2 or 4.0) must
wenzelm@59569
   588
    be installed, and the environment variable "OLD_Z3_SOLVER" must
wenzelm@59569
   589
    point to it.
blanchet@58062
   590
    INCOMPATIBILITY.
blanchet@58067
   591
  - The 'smt2' method has been renamed 'smt'.
blanchet@58060
   592
    INCOMPATIBILITY.
wenzelm@59569
   593
  - New option 'smt_reconstruction_step_timeout' to limit the
wenzelm@59569
   594
    reconstruction time of Z3 proof steps in the new 'smt' method.
boehmes@59216
   595
  - New option 'smt_statistics' to display statistics of the new 'smt'
boehmes@59216
   596
    method, especially runtime statistics of Z3 proof reconstruction.
blanchet@58060

wenzelm@60261
   598
* Lifting: command 'lift_definition' allows to execute lifted constants
wenzelm@60261
   599
that have as a return type a datatype containing a subtype. This
wenzelm@60261
   600
overcomes long-time limitations in the area of code generation and
wenzelm@60261
   601
lifting, and avoids tedious workarounds.
kuncar@60258
   602
wenzelm@60010
   603
* Command and antiquotation "value" provide different evaluation slots
wenzelm@60010
   604
(again), where the previous strategy (NBE after ML) serves as default.
wenzelm@60010
   605
Minor INCOMPATIBILITY.
wenzelm@60010
   606
wenzelm@60010
   607
* Add NO_MATCH-simproc, allows to check for syntactic non-equality.
wenzelm@60010
   608
wenzelm@60010
   609
* field_simps: Use NO_MATCH-simproc for distribution rules, to avoid
wenzelm@60010
   610
non-termination in case of distributing a division. With this change
wenzelm@60010
   611
field_simps is in some cases slightly less powerful, if it fails try to
wenzelm@60010
   612
add algebra_simps, or use divide_simps. Minor INCOMPATIBILITY.
wenzelm@60010
   613
wenzelm@60010
   614
* Separate class no_zero_divisors has been given up in favour of fully
wenzelm@60010
   615
algebraic semiring_no_zero_divisors. INCOMPATIBILITY.
wenzelm@60010
   616
wenzelm@60010
   617
* Class linordered_semidom really requires no zero divisors.
wenzelm@60010
   618
INCOMPATIBILITY.
wenzelm@60010
   619
wenzelm@60010
   620
* Classes division_ring, field and linordered_field always demand
wenzelm@60010
   621
"inverse 0 = 0". Given up separate classes division_ring_inverse_zero,
wenzelm@60010
   622
field_inverse_zero and linordered_field_inverse_zero. INCOMPATIBILITY.
wenzelm@60010
   623
wenzelm@60010
   624
* Classes cancel_ab_semigroup_add / cancel_monoid_add specify explicit
wenzelm@60010
   625
additive inverse operation. INCOMPATIBILITY.
wenzelm@60010
   626
lp15@60020
   627
* Complex powers and square roots. The functions "ln" and "powr" are now
wenzelm@60025
   628
overloaded for types real and complex, and 0 powr y = 0 by definition.
wenzelm@60025
   629
INCOMPATIBILITY: type constraints may be necessary.
lp15@60020
   630
wenzelm@60010
   631
* The functions "sin" and "cos" are now defined for any type of sort
wenzelm@60010
   632
"{real_normed_algebra_1,banach}" type, so in particular on "real" and
wenzelm@60010
   633
"complex" uniformly. Minor INCOMPATIBILITY: type constraints may be
wenzelm@60010
   634
needed.
wenzelm@60010
   635
wenzelm@60010
   636
* New library of properties of the complex transcendental functions sin,
wenzelm@60010
   637
cos, tan, exp, Ln, Arctan, Arcsin, Arccos. Ported from HOL Light.
wenzelm@60010
   638
wenzelm@60010
   639
* The factorial function, "fact", now has type "nat => 'a" (of a sort
wenzelm@60010
   640
that admits numeric types including nat, int, real and complex.
wenzelm@60010
   641
INCOMPATIBILITY: an expression such as "fact 3 = 6" may require a type
wenzelm@60010
   642
constraint, and the combination "real (fact k)" is likely to be
wenzelm@60010
   643
unsatisfactory. If a type conversion is still necessary, then use
wenzelm@60010
   644
"of_nat (fact k)" or "real_of_nat (fact k)".
wenzelm@60010
   645
wenzelm@60010
   646
* Removed functions "natfloor" and "natceiling", use "nat o floor" and
wenzelm@60010
   647
"nat o ceiling" instead. A few of the lemmas have been retained and
wenzelm@60010
   648
adapted: in their names "natfloor"/"natceiling" has been replaced by
wenzelm@60010
   649
"nat_floor"/"nat_ceiling".
wenzelm@60010
   650
wenzelm@60010
   651
* Qualified some duplicated fact names required for boostrapping the
wenzelm@60010
   652
type class hierarchy:
wenzelm@60010
   653
  ab_add_uminus_conv_diff ~> diff_conv_add_uminus
wenzelm@60010
   654
  field_inverse_zero ~> inverse_zero
wenzelm@60010
   655
  field_divide_inverse ~> divide_inverse
wenzelm@60010
   656
  field_inverse ~> left_inverse
wenzelm@60010
   657
Minor INCOMPATIBILITY.
wenzelm@60010
   658
wenzelm@60010
   659
* Eliminated fact duplicates:
wenzelm@60010
   660
  mult_less_imp_less_right ~> mult_right_less_imp_less
wenzelm@60010
   661
  mult_less_imp_less_left ~> mult_left_less_imp_less
wenzelm@60010
   662
Minor INCOMPATIBILITY.
wenzelm@60010
   663
wenzelm@60010
   664
* Fact consolidation: even_less_0_iff is subsumed by
wenzelm@60010
   665
double_add_less_zero_iff_single_add_less_zero (simp by default anyway).
wenzelm@60010
   666
wenzelm@60010
   667
* Generalized and consolidated some theorems concerning divsibility:
wenzelm@60010
   668
  dvd_reduce ~> dvd_add_triv_right_iff
wenzelm@60010
   669
  dvd_plus_eq_right ~> dvd_add_right_iff
wenzelm@60010
   670
  dvd_plus_eq_left ~> dvd_add_left_iff
wenzelm@60010
   671
Minor INCOMPATIBILITY.
wenzelm@60010
   672
wenzelm@60010
   673
* "even" and "odd" are mere abbreviations for "2 dvd _" and "~ 2 dvd _"
wenzelm@60010
   674
and part of theory Main.
wenzelm@60010
   675
  even_def ~> even_iff_mod_2_eq_zero
wenzelm@60010
   676
INCOMPATIBILITY.
wenzelm@60010
   677
wenzelm@60010
   678
* Lemma name consolidation: divide_Numeral1 ~> divide_numeral_1. Minor
wenzelm@60010
   679
INCOMPATIBILITY.
wenzelm@60010
   680
wenzelm@60010
   681
* Bootstrap of listsum as special case of abstract product over lists.
wenzelm@60010
   682
Fact rename:
wenzelm@60010
   683
    listsum_def ~> listsum.eq_foldr
wenzelm@60010
   684
INCOMPATIBILITY.
wenzelm@60010
   685
wenzelm@60010
   686
* Product over lists via constant "listprod".
wenzelm@60010
   687
wenzelm@60010
   688
* Theory List: renamed drop_Suc_conv_tl and nth_drop' to
wenzelm@60010
   689
Cons_nth_drop_Suc.
nipkow@58247
   690
Andreas@58626
   691
* New infrastructure for compiling, running, evaluating and testing
wenzelm@59569
   692
generated code in target languages in HOL/Library/Code_Test. See
wenzelm@59569
   693
HOL/Codegenerator_Test/Code_Test* for examples.
wenzelm@58008
   694
wenzelm@60010
   695
* Library/Multiset:
blanchet@59813
   696
  - Introduced "replicate_mset" operation.
blanchet@59813
   697
  - Introduced alternative characterizations of the multiset ordering in
blanchet@59813
   698
    "Library/Multiset_Order".
blanchet@59958
   699
  - Renamed multiset ordering:

      \<subseteq># ~> #\<subseteq>#
blanchet@59958
   704
    INCOMPATIBILITY.
blanchet@59986
   705
  - Introduced abbreviations for ill-named multiset operations:
blanchet@59986
   706
      <#, \<subset># abbreviate < (strict subset)
blanchet@59986
   707
      <=#, \<le>#, \<subseteq># abbreviate <= (subset or equal)
blanchet@59986
   708
    INCOMPATIBILITY.
blanchet@59813
   709
  - Renamed
blanchet@59813
   710
      in_multiset_of ~> in_multiset_in_set
nipkow@59998
   711
      Multiset.fold ~> fold_mset
nipkow@59998

      Multiset.filter ~> filter_mset
blanchet@59813
   713
    INCOMPATIBILITY.
nipkow@59949
   714
  - Removed mcard, is equal to size.
blanchet@59813
   715

    INCOMPATIBILITY.
blanchet@59813
   725
wenzelm@60010
   726
* Library/Sum_of_Squares: simplified and improved "sos" method. Always
wenzelm@60010
   727
use local CSDP executable, which is much faster than the NEOS server.
wenzelm@60010
   728
The "sos_cert" functionality is invoked as "sos" with additional
wenzelm@60010
   729
argument. Minor INCOMPATIBILITY.
wenzelm@60010
   730
wenzelm@60010
   731
* HOL-Decision_Procs: New counterexample generator quickcheck
wenzelm@60010
   732
[approximation] for inequalities of transcendental functions. Uses
wenzelm@60010
   733
hardware floating point arithmetic to randomly discover potential
wenzelm@60011
   734
counterexamples. Counterexamples are certified with the "approximation"
wenzelm@60010
   735
method. See HOL/Decision_Procs/ex/Approximation_Quickcheck_Ex.thy for
wenzelm@60010
   736
examples.

* HOL-Probability: Reworked measurability prover
wenzelm@60011
   739
  - applies destructor rules repeatedly
hoelzl@59354
   740
  - removed application splitting (replaced by destructor rule)
wenzelm@59569
   741
  - added congruence rules to rewrite measure spaces under the sets
wenzelm@59569
   742
    projection
wenzelm@59569
   743
wenzelm@60010
   744

*** ML ***
blanchet@58066
   749
wenzelm@60010
   750
* Subtle change of name space policy: undeclared entries are now
wenzelm@60010
   751
considered inaccessible, instead of accessible via the fully-qualified
wenzelm@60010
   752
internal name. This mainly affects Name_Space.intern (and derivatives),
wenzelm@60010
   753
which may produce an unexpected Long_Name.hidden prefix. Note that
wenzelm@60011
   754
contemporary applications use the strict Name_Space.check (and
wenzelm@60010
   755
derivatives) instead, which is not affected by the change. Potential
wenzelm@60010
   756
INCOMPATIBILITY in rare applications of Name_Space.intern.
wenzelm@59951
   757
wenzelm@60096
   758
* Subtle change of error semantics of Toplevel.proof_of: regular user

   759
ERROR instead of internal Toplevel.UNDEF.
wenzelm@60096
   760
wenzelm@59951
   761
* Basic combinators map, fold, fold_map, split_list, apply are available
wenzelm@59951
   762
as parameterized antiquotations, e.g. @{map 4} for lists of quadruples.
wenzelm@59951
   763
wenzelm@59951
   764
* Renamed "pairself" to "apply2", in accordance to @{apply 2}.
wenzelm@59951
   765
INCOMPATIBILITY.
wenzelm@59951
   766
wenzelm@59951
   767
* Former combinators NAMED_CRITICAL and CRITICAL for central critical
wenzelm@59951
   768

wenzelm@59951
   769
Multithreading.synchronized and its high-level derivative
wenzelm@59951
   770
Synchronized.var (which is usually sufficient in applications). Subtle
wenzelm@59951
   771
INCOMPATIBILITY: synchronized access needs to be atomic and cannot be
wenzelm@59951
   772
nested.
wenzelm@59951
   773
wenzelm@60010
   774
* Synchronized.value (ML) is actually synchronized (as in Scala): subtle

   775
change of semantics with minimal potential for INCOMPATIBILITY.
wenzelm@59899
   776
wenzelm@59621
   777
* The main operations to certify logical entities are Thm.ctyp_of and
wenzelm@59621
   778
Thm.cterm_of with a local context; old-style global theory variants are
wenzelm@59621

   780
INCOMPATIBILITY.
wenzelm@59621

   791
PARALLEL_GOALS.
blanchet@58066

wenzelm@59564
   794
which also allows to specify a fork priority.
wenzelm@59564

* The Isabelle tool "build" provides new options -X, -k, -x.
wenzelm@59951
   810
wenzelm@59951
   811
* Discontinued old-fashioned "codegen" tool. Code generation can always
wenzelm@59951
   812
be externally triggered using an appropriate ROOT file plus a
wenzelm@59951
   813
corresponding theory. Parametrization is possible using environment
wenzelm@59951
   814
variables, or ML snippets in the most extreme cases. Minor
wenzelm@59951
   815
INCOMPATIBILITY.
wenzelm@58842
   816
wenzelm@59200
   817
* JVM system property "isabelle.threads" determines size of Scala thread
wenzelm@59200
   818
pool, like Isabelle system option "threads" for ML.
wenzelm@59200
   819
wenzelm@59201
   820
* JVM system property "isabelle.laf" determines the default Swing
wenzelm@59201
   821
look-and-feel, via internal class name or symbolic name as in the jEdit
wenzelm@59201
   822
menu Global Options / Appearance.
wenzelm@59201
   823
wenzelm@59951
   824
* Support for Proof General and Isar TTY loop has been discontinued.
wenzelm@60010

---------------------------------
wenzelm@54055
   831
wenzelm@54702
   832
*** General ***
wenzelm@54702
   833
wenzelm@57452
   834
* Support for official Standard ML within the Isabelle context.
wenzelm@57452
   835
Command 'SML_file' reads and evaluates the given Standard ML file.
wenzelm@57452
   836
Toplevel bindings are stored within the theory context; the initial
wenzelm@57452
   837
environment is restricted to the Standard ML implementation of
wenzelm@57452
   838
Poly/ML, without the add-ons of Isabelle/ML.  Commands 'SML_import'
wenzelm@57452
   839
and 'SML_export' allow to exchange toplevel bindings between the two
wenzelm@57452
   840
separate environments.  See also ~~/src/Tools/SML/Examples.thy for
wenzelm@57452
   841
some examples.
wenzelm@56499
   842
wenzelm@57504
   843
* Standard tactics and proof methods such as "clarsimp", "auto" and
wenzelm@57504
   844
"safe" now preserve equality hypotheses "x = expr" where x is a free
wenzelm@57504
   845
variable.  Locale assumptions and chained facts containing "x"
wenzelm@57504
   846
continue to be useful.  The new method "hypsubst_thin" and the
wenzelm@57504
   847
configuration option "hypsubst_thin" (within the attribute name space)
wenzelm@57504
   848
restore the previous behavior.  INCOMPATIBILITY, especially where
wenzelm@57504
   849
induction is done after these methods or when the names of free and
wenzelm@57504
   850
bound variables clash.  As first approximation, old proofs may be
wenzelm@57504
   851
repaired by "using [[hypsubst_thin = true]]" in the critical spot.
wenzelm@57504
   852
wenzelm@56232
   853
* More static checking of proof methods, which allows the system to
wenzelm@56232
   854
form a closure over the concrete syntax.  Method arguments should be
wenzelm@56232
   855
processed in the original proof context as far as possible, before
wenzelm@56232
   856
operating on the goal state.  In any case, the standard discipline for
wenzelm@56232
   857
subgoal-addressing needs to be observed: no subgoals or a subgoal
wenzelm@56232
   858
number that is out of range produces an empty result sequence, not an
wenzelm@56232
   859
exception.  Potential INCOMPATIBILITY for non-conformant tactical
wenzelm@56232
   860
proof tools.
wenzelm@56232
   861
wenzelm@57452
   862
* Lexical syntax (inner and outer) supports text cartouches with
wenzelm@57452
   863
arbitrary nesting, and without escapes of quotes etc.  The Prover IDE
wenzelm@57452
   864
supports input via ` (backquote).
wenzelm@57452
   865
wenzelm@57452
   866
* The outer syntax categories "text" (for formal comments and document
wenzelm@57452
   867
markup commands) and "altstring" (for literal fact references) allow
wenzelm@57452
   868
cartouches as well, in addition to the traditional mix of quotations.
wenzelm@57452
   869
wenzelm@57452
   870
* Syntax of document antiquotation @{rail} now uses \<newline> instead
wenzelm@57452
   871
of "\\", to avoid the optical illusion of escaped backslash within
wenzelm@57491
   872
string token.  General renovation of its syntax using text cartouches.
wenzelm@57452
   873
Minor INCOMPATIBILITY.
wenzelm@57452
   874
wenzelm@57452
   875
* Discontinued legacy_isub_isup, which was a temporary workaround for
wenzelm@57452
   876
Isabelle/ML in Isabelle2013-1.  The prover process no longer accepts
wenzelm@57452
   877
old identifier syntax with \<^isub> or \<^isup>.  Potential
wenzelm@57452
   878
INCOMPATIBILITY.
wenzelm@57452
   879
wenzelm@57452
   880
* Document antiquotation @{url} produces markup for the given URL,
wenzelm@57452
   881
which results in an active hyperlink within the text.
wenzelm@57452
   882
wenzelm@57452
   883
* Document antiquotation @{file_unchecked} is like @{file}, but does
wenzelm@57452
   884
not check existence within the file-system.
wenzelm@57452
   885
wenzelm@57452
   886
* Updated and extended manuals: codegen, datatypes, implementation,
wenzelm@57452
   887
isar-ref, jedit, system.
wenzelm@57423

   890
*** Prover IDE -- Isabelle/Scala/jEdit ***
wenzelm@54533
   891
wenzelm@57650
   892
* Improved Document panel: simplified interaction where every single
wenzelm@57452
   893
mouse click (re)opens document via desktop environment or as jEdit
wenzelm@57452
   894
buffer.
wenzelm@57452
   895
wenzelm@57452
   896
* Support for Navigator plugin (with toolbar buttons), with connection
wenzelm@57452
   897
to PIDE hyperlinks.
wenzelm@57452
   898
wenzelm@57452
   899
* Auxiliary files ('ML_file' etc.) are managed by the Prover IDE.
wenzelm@57452
   900
Open text buffers take precedence over copies within the file-system.
wenzelm@57452
   901
wenzelm@57452
   902
* Improved support for Isabelle/ML, with jEdit mode "isabelle-ml" for
wenzelm@57452
   903
auxiliary ML files.
wenzelm@57423
   904
wenzelm@57423
   905
* Improved syntactic and semantic completion mechanism, with simple
wenzelm@57423
   906
templates, completion language context, name-space completion,
wenzelm@57423
   907
file-name completion, spell-checker completion.
wenzelm@57423
   908
wenzelm@57423
   909
* Refined GUI popup for completion: more robust key/mouse event
wenzelm@57423
   910
handling and propagation to enclosing text area -- avoid loosing
wenzelm@57423
   911
keystrokes with slow / remote graphics displays.
wenzelm@57423
   912
wenzelm@57833
   913
* Completion popup supports both ENTER and TAB (default) to select an
wenzelm@57833
   914
item, depending on Isabelle options.
wenzelm@57833
   915
wenzelm@57423
   916
* Refined insertion of completion items wrt. jEdit text: multiple
wenzelm@57423
   917
selections, rectangular selections, rectangular selection as "tall
wenzelm@57423
   918
caret".
wenzelm@56342
   919
wenzelm@56580
   920
* Integrated spell-checker for document text, comments etc. with
wenzelm@57423
   921
completion popup and context-menu.
wenzelm@56554
   922
wenzelm@56879
   923
* More general "Query" panel supersedes "Find" panel, with GUI access
wenzelm@56879
   924
to commands 'find_theorems' and 'find_consts', as well as print
wenzelm@56879
   925
operations for the context.  Minor incompatibility in keyboard
wenzelm@56879
   926
shortcuts etc.: replace action isabelle-find by isabelle-query.
wenzelm@56761
   927
wenzelm@56901
   928
* Search field for all output panels ("Output", "Query", "Info" etc.)
wenzelm@56901
   929
to highlight text via regular expression.
wenzelm@56901
   930
wenzelm@54881
   931
* Option "jedit_print_mode" (see also "Plugin Options / Isabelle /
wenzelm@54881
   932
General") allows to specify additional print modes for the prover
wenzelm@54881
   933
process, without requiring old-fashioned command-line invocation of
wenzelm@54881
   934
"isabelle jedit -m MODE".
wenzelm@54881
   935
wenzelm@56505
   936
* More support for remote files (e.g. http) using standard Java
wenzelm@56505
   937
networking operations instead of jEdit virtual file-systems.
wenzelm@56505
   938
wenzelm@57822
   939
* Empty editors buffers that are no longer required (e.g.\ via theory
wenzelm@57822
   940
imports) are automatically removed from the document model.
wenzelm@57822
   941
wenzelm@57869
   942
* Improved monitor panel.
wenzelm@57869
   943
wenzelm@56838
   944
* Improved Console/Scala plugin: more uniform scala.Console output,
wenzelm@56838
   945
more robust treatment of threads and interrupts.
wenzelm@56838
   946
wenzelm@56939
   947
* Improved management of dockable windows: clarified keyboard focus
wenzelm@56939
   948
and window placement wrt. main editor view; optional menu item to
wenzelm@56939
   949
"Detach" a copy where this makes sense.
wenzelm@56939
   950
wenzelm@57452
   951
* New Simplifier Trace panel provides an interactive view of the
wenzelm@57594
   952
simplification process, enabled by the "simp_trace_new" attribute
wenzelm@57452
   953
within the context.

wenzelm@55001
   956
*** Pure ***
wenzelm@55001
   957
wenzelm@57504
   958
* Low-level type-class commands 'classes', 'classrel', 'arities' have
wenzelm@57504
   959
been discontinued to avoid the danger of non-trivial axiomatization
wenzelm@57504
   960
that is not immediately visible.  INCOMPATIBILITY, use regular
wenzelm@57504
   961
'instance' command with proof.  The required OFCLASS(...) theorem
wenzelm@57504
   962
might be postulated via 'axiomatization' beforehand, or the proof
wenzelm@57504
   963
finished trivially if the underlying class definition is made vacuous
wenzelm@57504
   964
(without any assumptions).  See also Isabelle/ML operations
wenzelm@57504
   965
Axclass.class_axiomatization, Axclass.classrel_axiomatization,
wenzelm@57504
   966
Axclass.arity_axiomatization.
wenzelm@57504
   967
wenzelm@56245
   968
* Basic constants of Pure use more conventional names and are always
wenzelm@56245
   969
qualified.  Rare INCOMPATIBILITY, but with potentially serious
wenzelm@56245
   970
consequences, notably for tools in Isabelle/ML.  The following
wenzelm@56245
   971
renaming needs to be applied:
wenzelm@56245
   972
wenzelm@56245
   973
  ==             ~>  Pure.eq
wenzelm@56245
   974
  ==>            ~>  Pure.imp
wenzelm@56245
   975
  all            ~>  Pure.all
wenzelm@56245
   976
  TYPE           ~>  Pure.type
wenzelm@56245
   977
  dummy_pattern  ~>  Pure.dummy_pattern
wenzelm@56245
   978
wenzelm@56245
   979
Systematic porting works by using the following theory setup on a
wenzelm@56245
   980
*previous* Isabelle version to introduce the new name accesses for the
wenzelm@56245
   981
old constants:
wenzelm@56245
   982
wenzelm@56245
   983
setup {*
wenzelm@56245
   984
  fn thy => thy
wenzelm@56245
   985
    |> Sign.root_path
wenzelm@56245
   986
    |> Sign.const_alias (Binding.qualify true "Pure" @{binding eq}) "=="
wenzelm@56245
   987
    |> Sign.const_alias (Binding.qualify true "Pure" @{binding imp}) "==>"
wenzelm@56245
   988
    |> Sign.const_alias (Binding.qualify true "Pure" @{binding all}) "all"
wenzelm@56245
   989
    |> Sign.restore_naming thy
wenzelm@56245
   990
*}
wenzelm@56245
   991
wenzelm@56245
   992
Thus ML antiquotations like @{const_name Pure.eq} may be used already.
wenzelm@56245
   993
Later the application is moved to the current Isabelle version, and
wenzelm@56245
   994
the auxiliary aliases are deleted.
wenzelm@56245
   995
wenzelm@55143
   996
* Attributes "where" and "of" allow an optional context of local
wenzelm@55143
   997
variables ('for' declaration): these variables become schematic in the
wenzelm@55143
   998
instantiated theorem.
wenzelm@55143
   999
wenzelm@55152
  1000
* Obsolete attribute "standard" has been discontinued (legacy since
wenzelm@55152
  1001
Isabelle2012).  Potential INCOMPATIBILITY, use explicit 'for' context
wenzelm@55152
  1002
where instantiations with schematic variables are intended (for
wenzelm@55152
  1003
declaration commands like 'lemmas' or attributes like "of").  The
wenzelm@55152
  1004
following temporary definition may help to port old applications:
wenzelm@55152
  1005
wenzelm@55152
  1006
  attribute_setup standard =
wenzelm@55152
  1007
    "Scan.succeed (Thm.rule_attribute (K Drule.export_without_context))"
wenzelm@55152
  1008
wenzelm@55001
  1009
* More thorough check of proof context for goal statements and
wenzelm@55006
  1010
attributed fact expressions (concerning background theory, declared
wenzelm@55006
  1011
hyps).  Potential INCOMPATIBILITY, tools need to observe standard
wenzelm@55006
  1012
context discipline.  See also Assumption.add_assumes and the more
wenzelm@55006
  1013
primitive Thm.assume_hyps.
wenzelm@55001
  1014
wenzelm@55108
  1015
* Inner syntax token language allows regular quoted strings "..."
wenzelm@55108
  1016
(only makes sense in practice, if outer syntax is delimited
wenzelm@57452
  1017
differently, e.g. via cartouches).
wenzelm@57452
  1018
wenzelm@57504
  1019
* Command 'print_term_bindings' supersedes 'print_binds' for clarity,
wenzelm@57504
  1020
but the latter is retained some time as Proof General legacy.
wenzelm@57504
  1021
wenzelm@57452
  1022
* Code generator preprocessor: explicit control of simp tracing on a
wenzelm@57452
  1023
per-constant basis.  See attribute "code_preproc".

INCOMPATIBILITY.
wenzelm@57504
  1036
wenzelm@57504
  1037

* Renamed command 'enriched_type' to 'functor'. INCOMPATIBILITY.
wenzelm@57504
  1053
wenzelm@57504
  1054
* The symbol "\<newline>" may be used within char or string literals
wenzelm@57504
  1055
to represent (Char Nibble0 NibbleA), i.e. ASCII newline.
wenzelm@57504

* Simplifier: Enhanced solver of preconditions of rewrite rules can
wenzelm@57452
  1060
now deal with conjunctions.  For help with converting proofs, the old
wenzelm@57452
  1061
behaviour of the simplifier can be restored like this: declare/using
wenzelm@57452
  1062
[[simp_legacy_precond]].  This configuration option will disappear

wenzelm@57508
  1217
* New internal SAT solver "cdclite" that produces models and proof
wenzelm@57508
  1218
traces.  This solver replaces the internal SAT solvers "enumerate" and
wenzelm@57508
  1219
"dpll".  Applications that explicitly used one of these two SAT
wenzelm@57508
  1220
solvers should use "cdclite" instead. In addition, "cdclite" is now
wenzelm@57508
  1221
the default SAT solver for the "sat" and "satx" proof methods and
wenzelm@57508
  1222
corresponding tactics; the old default can be restored using "declare
wenzelm@57508
  1223
[[sat_solver = zchaff_with_proofs]]".  Minor INCOMPATIBILITY.
wenzelm@57508
  1224
wenzelm@57508
  1225
* SMT module: A new version of the SMT module, temporarily called
wenzelm@57508
  1226
"SMT2", uses SMT-LIB 2 and supports recent versions of Z3 (e.g.,
wenzelm@57508
  1227
4.3). The new proof method is called "smt2". CVC3 and CVC4 are also
wenzelm@57508
  1228
supported as oracles. Yices is no longer supported, because no version
wenzelm@57508
  1229
of the solver can handle both SMT-LIB 2 and quantifiers.
wenzelm@57508
  1230
wenzelm@57508
  1231
* Activation of Z3 now works via "z3_non_commercial" system option
wenzelm@57508
  1232
(without requiring restart), instead of former settings variable
wenzelm@57508
  1233
"Z3_NON_COMMERCIAL".  The option can be edited in Isabelle/jEdit menu

* Sledgehammer:
wenzelm@57508
  1237
  - Z3 can now produce Isar proofs.
wenzelm@57508
  1238
  - MaSh overhaul:
blanchet@57532
  1239
    . New SML-based learning algorithms eliminate the dependency on
wenzelm@57508
  1240
      Python and increase performance and reliability.
wenzelm@57508
  1241
    . MaSh and MeSh are now used by default together with the
wenzelm@57508
  1242
      traditional MePo (Meng-Paulson) relevance filter. To disable
wenzelm@57508
  1243
      MaSh, set the "MaSh" system option in Isabelle/jEdit Plugin
wenzelm@57508
  1244
      Options / Isabelle / General to "none".
wenzelm@57508
  1245
  - New option:
wenzelm@57508
  1246
      smt_proofs
wenzelm@57508
  1247
  - Renamed options:

  1251
INCOMPATIBILITY.
wenzelm@57508
  1252
wenzelm@57508
  1253
* Removed solvers remote_cvc3 and remote_z3. Use cvc3 and z3 instead.
wenzelm@57508
  1254
wenzelm@57508
  1255
* Nitpick:
wenzelm@57508
  1256
  - Fixed soundness bug whereby mutually recursive datatypes could
wenzelm@57508
  1257
    take infinite values.
wenzelm@57508
  1258
  - Fixed soundness bug with low-level number functions such as
wenzelm@57508
  1259
    "Abs_Integ" and "Rep_Integ".
wenzelm@57508
  1260
  - Removed "std" option.
wenzelm@57508
  1261
  - Renamed "show_datatypes" to "show_types" and "hide_datatypes" to
wenzelm@57508
  1262
    "hide_types".
wenzelm@57508
  1263
wenzelm@57508
  1264
* Metis: Removed legacy proof method 'metisFT'. Use 'metis
wenzelm@57508
  1265
(full_types)' instead. INCOMPATIBILITY.
wenzelm@57508
  1266
wenzelm@57508
  1267
* Try0: Added 'algebra' and 'meson' to the set of proof methods.
wenzelm@57508
  1268
wenzelm@57508
  1269
* Adjustion of INF and SUP operations:
wenzelm@57508
  1270
  - Elongated constants INFI and SUPR to INFIMUM and SUPREMUM.
wenzelm@57508
  1271
  - Consolidated theorem names containing INFI and SUPR: have INF and
wenzelm@57508
  1272
    SUP instead uniformly.
wenzelm@57508
  1273
  - More aggressive normalization of expressions involving INF and Inf
wenzelm@57508
  1274
    or SUP and Sup.
wenzelm@57508
  1275
  - INF_image and SUP_image do not unfold composition.
wenzelm@57508
  1276
  - Dropped facts INF_comp, SUP_comp.
wenzelm@57508
  1277
  - Default congruence rules strong_INF_cong and strong_SUP_cong, with
wenzelm@57508
  1278
    simplifier implication in premises.  Generalize and replace former
wenzelm@57508
  1279
    INT_cong, SUP_cong
wenzelm@57508

wenzelm@57508
  1281
INCOMPATIBILITY.
wenzelm@57508
  1282
wenzelm@57508
  1283
* SUP and INF generalized to conditionally_complete_lattice.
wenzelm@57508
  1284
wenzelm@57508
  1285
* Swapped orientation of facts image_comp and vimage_comp:

wenzelm@55622
  1815
wenzelm@57452
  1816
* Substantial reworking of internal PIDE protocol communication
wenzelm@57452
  1817

*** ML ***
wenzelm@54449
  1821
wenzelm@57504
  1822
* Subtle change of semantics of Thm.eq_thm: theory stamps are not
wenzelm@57504
  1823
compared (according to Thm.thm_ord), but assumed to be covered by the
wenzelm@57504
  1824
current background theory.  Thus equivalent data produced in different
wenzelm@57504
  1825
branches of the theory graph usually coincides (e.g. relevant for
wenzelm@57504
  1826
theory merge).  Note that the softer Thm.eq_thm_prop is often more
wenzelm@57504
  1827
appropriate than Thm.eq_thm.
wenzelm@57504
  1828
wenzelm@57504
  1829
* Proper context for basic Simplifier operations: rewrite_rule,
wenzelm@57504
  1830
rewrite_goals_rule, rewrite_goals_tac etc. INCOMPATIBILITY, need to
wenzelm@57504
  1831
pass runtime Proof.context (and ensure that the simplified entity
wenzelm@57504
  1832
actually belongs to it).
wenzelm@57504
  1833
wenzelm@57504
  1834
* Proper context discipline for read_instantiate and instantiate_tac:
wenzelm@57504
  1835
variables that are meant to become schematic need to be given as
wenzelm@57504
  1836
fixed, and are generalized by the explicit context of local variables.
wenzelm@57504
  1837
This corresponds to Isar attributes "where" and "of" with 'for'
wenzelm@57504
  1838
declaration.  INCOMPATIBILITY, also due to potential change of indices
wenzelm@57504
  1839
of schematic variables.
wenzelm@57504
  1840
wenzelm@56303
  1841
* Moved ML_Compiler.exn_trace and other operations on exceptions to
wenzelm@56303
  1842
structure Runtime.  Minor INCOMPATIBILITY.
wenzelm@56303
  1843
wenzelm@56279
  1844
* Discontinued old Toplevel.debug in favour of system option
wenzelm@57452
  1845
"ML_exception_trace", which may be also declared within the context
wenzelm@57452
  1846
via "declare [[ML_exception_trace = true]]".  Minor INCOMPATIBILITY.
wenzelm@56279
  1847
wenzelm@56281
  1848
* Renamed configuration option "ML_trace" to "ML_source_trace". Minor
wenzelm@56281
  1849
INCOMPATIBILITY.
wenzelm@56281
  1850
wenzelm@56281
  1851
* Configuration option "ML_print_depth" controls the pretty-printing
wenzelm@56281
  1852
depth of the ML compiler within the context.  The old print_depth in
wenzelm@56285
  1853
ML is still available as default_print_depth, but rarely used.  Minor
wenzelm@56285
  1854
INCOMPATIBILITY.
wenzelm@56279
  1855
wenzelm@54449
  1856
* Toplevel function "use" refers to raw ML bootstrap environment,
wenzelm@54449
  1857
without Isar context nor antiquotations.  Potential INCOMPATIBILITY.
wenzelm@54449
  1858
Note that 'ML_file' is the canonical command to load ML files into the
wenzelm@54449
  1859
formal context.
wenzelm@54449
  1860
wenzelm@56205
  1861
* Simplified programming interface to define ML antiquotations, see
wenzelm@56205
  1862
structure ML_Antiquotation.  Minor INCOMPATIBILITY.
wenzelm@56069
  1863
wenzelm@56071
  1864
* ML antiquotation @{here} refers to its source position, which is
wenzelm@56071
  1865
occasionally useful for experimentation and diagnostic purposes.
wenzelm@56071
  1866
wenzelm@56135
  1867
* ML antiquotation @{path} produces a Path.T value, similarly to
wenzelm@56135
  1868
Path.explode, but with compile-time check against the file-system and
wenzelm@56135
  1869
some PIDE markup.  Note that unlike theory source, ML does not have a
wenzelm@56135
  1870
well-defined master directory, so an absolute symbolic path
wenzelm@56135
  1871
specification is usually required, e.g. "~~/src/HOL".
wenzelm@56135
  1872
wenzelm@56399
  1873
* ML antiquotation @{print} inlines a function to print an arbitrary
wenzelm@56399
  1874
ML value, which is occasionally useful for diagnostic or demonstration
wenzelm@56399
  1875
purposes.

wenzelm@57504
  1881
Isabelle component, e.g. see ProofGeneral-4.2-2 from the Isabelle
wenzelm@57504
  1882
component repository http://isabelle.in.tum.de/components/.  Note that
wenzelm@57504
  1883
the "system" manual provides general explanations about add-on
wenzelm@57504
  1884
components, especially those that are not bundled with the release.
wenzelm@57443
  1885
wenzelm@56439
  1886
* The raw Isabelle process executable has been renamed from
wenzelm@56439
  1887
"isabelle-process" to "isabelle_process", which conforms to common
wenzelm@56439
  1888
shell naming conventions, and allows to define a shell function within
wenzelm@56439
  1889
the Isabelle environment to avoid dynamic path lookup.  Rare
wenzelm@57504
  1890
incompatibility for old tools that do not use the ISABELLE_PROCESS
wenzelm@57504
  1891
settings variable.
wenzelm@56439
  1892
wenzelm@57439
  1893
* Former "isabelle tty" has been superseded by "isabelle console",
wenzelm@57439
  1894
with implicit build like "isabelle jedit", and without the mostly
wenzelm@57439
  1895
obsolete Isar TTY loop.
wenzelm@57439
  1896
wenzelm@57452
  1897
* Simplified "isabelle display" tool.  Settings variables DVI_VIEWER
wenzelm@57452
  1898
and PDF_VIEWER now refer to the actual programs, not shell
wenzelm@57452
  1899
command-lines.  Discontinued option -c: invocation may be asynchronous
wenzelm@57452
  1900
via desktop environment, without any special precautions.  Potential
wenzelm@57452
  1901
INCOMPATIBILITY with ambitious private settings.
wenzelm@57452
  1902
wenzelm@57413
  1903
* Removed obsolete "isabelle unsymbolize".  Note that the usual format
wenzelm@57413
  1904
for email communication is the Unicode rendering of Isabelle symbols,
wenzelm@57413
  1905
as produced by Isabelle/jEdit, for example.
wenzelm@57413
  1906
wenzelm@57452
  1907
* Removed obsolete tool "wwwfind". Similar functionality may be
wenzelm@57452
  1908
integrated into Isabelle/jEdit eventually.
wenzelm@57452
  1909
wenzelm@57452
  1910
* Improved 'display_drafts' concerning desktop integration and
wenzelm@57452
  1911
repeated invocation in PIDE front-end: re-use single file
wenzelm@57452
  1912
$ISABELLE_HOME_USER/tmp/drafts.pdf and corresponding views.
wenzelm@57084
  1913
wenzelm@57452
  1914
* Session ROOT specifications require explicit 'document_files' for
wenzelm@57452
  1915
robust dependencies on LaTeX sources.  Only these explicitly given
wenzelm@57452
  1916
files are copied to the document output directory, before document
wenzelm@57452
  1917
processing is started.
wenzelm@57452
  1918
wenzelm@57504
  1919
* Windows: support for regular TeX installation (e.g. MiKTeX) instead
wenzelm@57504
  1920
of TeX Live from Cygwin.

e.g. non-terminating 'by' steps.
wenzelm@54639
  1931
wenzelm@54641

wenzelm@54641
  1934
wenzelm@54648

  1956
*** General ***
wenzelm@51293
  1957
wenzelm@53971
  1958
* Discontinued obsolete 'uses' within theory header.  Note that
wenzelm@53971
  1959
commands like 'ML_file' work without separate declaration of file
wenzelm@53971
  1960

'ML_file' in Isabelle2013.  Minor INCOMPATIBILITY.
wenzelm@53971
  1964
wenzelm@53016
  1965
* Simplified subscripts within identifiers, using plain \<^sub>
wenzelm@53016
  1966
instead of the second copy \<^isub> and \<^isup>.  Superscripts are
wenzelm@53016
  1967
only for literal tokens within notation; explicit mixfix annotations
wenzelm@53016
  1968
for consts or fixed variables may be used as fall-back for unusual
wenzelm@53016
  1969
names.  Obsolete \<twosuperior> has been expanded to \<^sup>2 in
wenzelm@53016
  1970
Isabelle/HOL.  INCOMPATIBILITY, use "isabelle update_sub_sup" to
wenzelm@53016
  1971
standardize symbols as a starting point for further manual cleanup.
wenzelm@53016
  1972
The ML reference variable "legacy_isub_isup" may be set as temporary
wenzelm@53016
  1973

  1974
syntax.
wenzelm@53016
  1975
wenzelm@53021
  1976

wenzelm@52487
  1979
* Uniform management of "quick_and_dirty" as system option (see also
wenzelm@52487
  1980
"isabelle options"), configuration option within the context (see also
wenzelm@52487
  1981
Config.get in Isabelle/ML), and attribute in Isabelle/Isar.  Minor
wenzelm@52487
  1982
INCOMPATIBILITY, need to use more official Isabelle means to access
wenzelm@52487
  1983
quick_and_dirty, instead of historical poking into mutable reference.
wenzelm@52059
  1984
wenzelm@52060
  1985
* Renamed command 'print_configs' to 'print_options'.  Minor

  1986
INCOMPATIBILITY.
wenzelm@52060
  1987
wenzelm@52430
  1988
* Proper diagnostic command 'print_state'.  Old 'pr' (with its
wenzelm@52430
  1989
implicit change of some global references) is retained for now as
wenzelm@52430
  1990
control command, e.g. for ProofGeneral 3.7.x.
wenzelm@52430
  1991
wenzelm@52549
  1992
* Discontinued 'print_drafts' command with its old-fashioned PS output
wenzelm@52549
  1993
and Unix command-line print spooling.  Minor INCOMPATIBILITY: use
wenzelm@52549
  1994
'display_drafts' instead and print via the regular document viewer.
wenzelm@52549
  1995
wenzelm@53971
  1996

wenzelm@53050
  2011
* Dockable window "Sledgehammer" manages asynchronous / parallel

wenzelm@53050
  2013
normal editing and checking process.
wenzelm@53050

  2015
* Dockable window "Timing" provides an overview of relevant command
wenzelm@54332
  2016
timing information, depending on option jedit_timing_threshold.  The
wenzelm@54332
  2017
same timing information is shown in the extended tooltip of the
wenzelm@54332
  2018

wenzelm@53971
  2022
document (visible and required parts) may be controlled explicitly,
wenzelm@53971
  2023
using check box or shortcut "C+e ENTER".  Individual theory nodes may
wenzelm@53971

wenzelm@54305
  2030
wenzelm@54319
  2031
* Standard jEdit keyboard shortcut C+b complete-word is remapped to
wenzelm@54319
  2032
isabelle.complete for explicit completion in Isabelle sources.
wenzelm@54319
  2033
INCOMPATIBILITY wrt. jEdit defaults, may have to invent new shortcuts
wenzelm@54319
  2034
to resolve conflict.
wenzelm@54319
  2035
wenzelm@54305
  2036
* Improved support of various "minor modes" for Isabelle NEWS,
wenzelm@54305
  2037
options, session ROOT etc., with completion and SideKick tree view.
wenzelm@54305
  2038
wenzelm@53971
  2039
* Strictly monotonic document update, without premature cancellation of
wenzelm@53971
  2040
running transactions that are still needed: avoid reset/restart of
wenzelm@53971
  2041
such command executions while editing.
wenzelm@53271
  2042
wenzelm@53971
  2043
* Support for asynchronous print functions, as overlay to existing
wenzelm@53971
  2044

wenzelm@53971
  2045
wenzelm@53971
  2046
* Support for automatic tools in HOL, which try to prove or disprove
wenzelm@53971
  2047
toplevel theorem statements.
wenzelm@53971
  2048
wenzelm@53971
  2049
* Action isabelle.reset-font-size resets main text area font size
wenzelm@54365
  2050
according to Isabelle/Scala plugin option "jedit_font_reset_size" (see
wenzelm@54365
  2051
also "Plugin Options / Isabelle / General").  It can be bound to some
wenzelm@54365
  2052
keyboard shortcut by the user (e.g. C+0 and/or C+NUMPAD0).
wenzelm@53971
  2053
wenzelm@53971
  2054
* File specifications in jEdit (e.g. file browser) may refer to
wenzelm@54351
  2055
$ISABELLE_HOME and $ISABELLE_HOME_USER on all platforms.  Discontinued
wenzelm@54351
  2056
obsolete $ISABELLE_HOME_WINDOWS variable.
wenzelm@53971
  2057
wenzelm@53971
  2058

ballarin@54049
  2068
In particular, 'interpretation' allows for non-persistent
ballarin@54049
  2069

state of Proofterm.proofs is persistently compiled into logic images
wenzelm@53971
  2084
as required, notably HOL-Proofs.  Users no longer need to change

  2092
configuration option "unify_trace_failure" (global context only).
wenzelm@53971

* SELECT_GOAL now retains the syntactic context of the overall goal
wenzelm@52463

* Stronger precedence of syntax for big intersection and union on
wenzelm@54032
  2102
sets, in accordance with corresponding lattice operations.
wenzelm@54032
  2103
INCOMPATIBILITY.
wenzelm@54032

* Notation "{p:A. P}" now allows tuple patterns as well.
wenzelm@54032
  2106
wenzelm@54032
  2107
* Nested case expressions are now translated in a separate check phase
wenzelm@54032
  2108
rather than during parsing. The data for case combinators is separated
wenzelm@54032
  2109
from the datatype package. The declaration attribute
wenzelm@54032
  2110
"case_translation" can be used to register new case combinators:
wenzelm@54032
  2111
wenzelm@54032
  2112
  declare [[case_translation case_combinator constructor1 ... constructorN]]
haftmann@52637

haftmann@52435
  2114
* Code generator:
wenzelm@53160
  2115
  - 'code_printing' unifies 'code_const' / 'code_type' / 'code_class' /
wenzelm@53160
  2116
    'code_instance'.
wenzelm@53160
  2117
  - 'code_identifier' declares name hints for arbitrary identifiers in
wenzelm@53160
  2118
    generated code, subsuming 'code_modulename'.

wenzelm@53983
  2121
examples.
haftmann@52435
  2122
wenzelm@54032
  2123
* Attibute 'code': 'code' now declares concrete and abstract code
wenzelm@54032
  2124
equations uniformly.  Use explicit 'code equation' and 'code abstract'
wenzelm@54032
  2125
to distinguish both when desired.
wenzelm@54032
  2126
wenzelm@54032
  2127
* Discontinued theories Code_Integer and Efficient_Nat by a more
wenzelm@54032
  2128
fine-grain stack of theories Code_Target_Int, Code_Binary_Nat,
wenzelm@54032
  2129
Code_Target_Nat and Code_Target_Numeral.  See the tutorial on code
wenzelm@54032
  2130
generation for details.  INCOMPATIBILITY.
wenzelm@54032
  2131
wenzelm@54032
  2132
* Numeric types are mapped by default to target language numerals:
wenzelm@54032
  2133
natural (replaces former code_numeral) and integer (replaces former
wenzelm@54032
  2134
code_int).  Conversions are available as integer_of_natural /
wenzelm@54032
  2135
natural_of_integer / integer_of_nat / nat_of_integer (in HOL) and
wenzelm@54032
  2136
Code_Numeral.integer_of_natural / Code_Numeral.natural_of_integer (in
wenzelm@54032
  2137
ML).  INCOMPATIBILITY.
wenzelm@54032
  2138
wenzelm@54032
  2139
* Function package: For mutually recursive functions f and g, separate
wenzelm@54032
  2140
cases rules f.cases and g.cases are generated instead of unusable
wenzelm@54032
  2141
f_g.cases which exposed internal sum types. Potential INCOMPATIBILITY,
wenzelm@54032
  2142
in the case that the unusable rule was used nevertheless.
wenzelm@54032
  2143
wenzelm@54032
  2144
* Function package: For each function f, new rules f.elims are
wenzelm@54032
  2145
generated, which eliminate equalities of the form "f x = t".
wenzelm@54032
  2146
wenzelm@54032
  2147
* New command 'fun_cases' derives ad-hoc elimination rules for
wenzelm@54032
  2148
function equations as simplified instances of f.elims, analogous to
wenzelm@54032
  2149
inductive_cases.  See ~~/src/HOL/ex/Fundefs.thy for some examples.
blanchet@53307
  2150
kuncar@54021
  2151
* Lifting:
kuncar@54021
  2152
  - parametrized correspondence relations are now supported:
wenzelm@54378
  2153
    + parametricity theorems for the raw term can be specified in
kuncar@54021
  2154
      the command lift_definition, which allow us to generate stronger
kuncar@54021
  2155
      transfer rules
kuncar@54021
  2156
    + setup_lifting generates stronger transfer rules if parametric
kuncar@54021
  2157
      correspondence relation can be generated
kuncar@54021
  2158
    + various new properties of the relator must be specified to support
kuncar@54021
  2159
      parametricity
kuncar@54021
  2160
    + parametricity theorem for the Quotient relation can be specified
kuncar@54021
  2161
  - setup_lifting generates domain rules for the Transfer package
kuncar@54021
  2162
  - stronger reflexivity prover of respectfulness theorems for type
kuncar@54021
  2163
    copies
kuncar@54021
  2164
  - ===> and --> are now local. The symbols can be introduced
kuncar@54021
  2165
    by interpreting the locale lifting_syntax (typically in an
kuncar@54021
  2166
    anonymous context)
wenzelm@54378
  2167
  - Lifting/Transfer relevant parts of Library/Quotient_* are now in
kuncar@54021
  2168
    Main. Potential INCOMPATIBILITY
kuncar@54021
  2169
  - new commands for restoring and deleting Lifting/Transfer context:
kuncar@54021
  2170
    lifting_forget, lifting_update
wenzelm@54378
  2171
  - the command print_quotmaps was renamed to print_quot_maps.
kuncar@54021
  2172
    INCOMPATIBILITY
kuncar@54021
  2173
kuncar@54021
  2174
* Transfer:
wenzelm@54378
  2175
  - better support for domains in Transfer: replace Domainp T
kuncar@54021
  2176
    by the actual invariant in a transferred goal
kuncar@54021
  2177
  - transfer rules can have as assumptions other transfer rules
kuncar@54021
  2178
  - Experimental support for transferring from the raw level to the
kuncar@54021
  2179
    abstract level: Transfer.transferred attribute
kuncar@54021
  2180
  - Attribute version of the transfer method: untransferred attribute
kuncar@54021
  2181
haftmann@52286
  2182
* Reification and reflection:
wenzelm@53160
  2183
  - Reification is now directly available in HOL-Main in structure
wenzelm@53160
  2184
    "Reification".
wenzelm@53160
  2185
  - Reflection now handles multiple lists with variables also.
wenzelm@53160
  2186
  - The whole reflection stack has been decomposed into conversions.
haftmann@52286
  2187
INCOMPATIBILITY.
haftmann@52286
  2188
haftmann@51489
  2189
* Revised devices for recursive definitions over finite sets:
haftmann@51489
  2190
  - Only one fundamental fold combinator on finite set remains:
haftmann@51489
  2191
    Finite_Set.fold :: ('a => 'b => 'b) => 'b => 'a set => 'b
haftmann@51489
  2192
    This is now identity on infinite sets.
wenzelm@52745
  2193
  - Locales ("mini packages") for fundamental definitions with
haftmann@51489
  2194
    Finite_Set.fold: folding, folding_idem.
haftmann@51489
  2195
  - Locales comm_monoid_set, semilattice_order_set and
haftmann@51489
  2196
    semilattice_neutr_order_set for big operators on sets.
haftmann@51489
  2197
    See theory Big_Operators for canonical examples.
haftmann@51489
  2198
    Note that foundational constants comm_monoid_set.F and
haftmann@51489
  2199
    semilattice_set.F correspond to former combinators fold_image
haftmann@51489
  2200
    and fold1 respectively.  These are now gone.  You may use
haftmann@51490
  2201
    those foundational constants as substitutes, but it is
wenzelm@53983
  2202
    preferable to interpret the above locales accordingly.
haftmann@51489
  2203
  - Dropped class ab_semigroup_idem_mult (special case of lattice,
haftmann@51489
  2204
    no longer needed in connection with Finite_Set.fold etc.)
haftmann@51489
  2205
  - Fact renames:
haftmann@51489
  2206
      card.union_inter ~> card_Un_Int [symmetric]
haftmann@51489
  2207
      card.union_disjoint ~> card_Un_disjoint
haftmann@51489
  2208
INCOMPATIBILITY.
haftmann@51489
  2209
haftmann@51487
  2210
* Locale hierarchy for abstract orderings and (semi)lattices.
haftmann@51487
  2211
wenzelm@53526
  2212
* Complete_Partial_Order.admissible is defined outside the type class
wenzelm@53526
  2213
ccpo, but with mandatory prefix ccpo. Admissibility theorems lose the
wenzelm@53526
  2214
class predicate assumption or sort constraint when possible.
Andreas@53362
  2215
INCOMPATIBILITY.
Andreas@53362
  2216
wenzelm@53160
  2217
* Introduce type class "conditionally_complete_lattice": Like a
wenzelm@53160
  2218
complete lattice but does not assume the existence of the top and
wenzelm@53160
  2219
bottom elements.  Allows to generalize some lemmas about reals and
wenzelm@53160
  2220
extended reals.  Removed SupInf and replaced it by the instantiation
wenzelm@53160
  2221
of conditionally_complete_lattice for real. Renamed lemmas about
wenzelm@53160
  2222
conditionally-complete lattice from Sup_... to cSup_... and from
wenzelm@53160
  2223
Inf_...  to cInf_... to avoid hidding of similar complete lattice
wenzelm@53160
  2224
lemmas.
wenzelm@53160
  2225
wenzelm@53160
  2226
* Introduce type class linear_continuum as combination of
wenzelm@53160
  2227
conditionally-complete lattices and inner dense linorders which have
wenzelm@53160
  2228
more than one element.  INCOMPATIBILITY.
wenzelm@53160
  2229
wenzelm@53983
  2230
* Introduced type classes order_top and order_bot. The old classes top
wenzelm@53983
  2231
and bot only contain the syntax without assumptions.  INCOMPATIBILITY:
wenzelm@53983
  2232
Rename bot -> order_bot, top -> order_top
lammich@53683
  2233
wenzelm@53160
  2234
* Introduce type classes "no_top" and "no_bot" for orderings without
wenzelm@53160
  2235
top and bottom elements.
hoelzl@51732
  2236
hoelzl@51732
  2237
* Split dense_linorder into inner_dense_order and no_top, no_bot.
hoelzl@51732
  2238
hoelzl@51732
  2239
* Complex_Main: Unify and move various concepts from
wenzelm@53160
  2240
HOL-Multivariate_Analysis to HOL-Complex_Main.
hoelzl@51732
  2241
wenzelm@53983
  2242
 - Introduce type class (lin)order_topology and
wenzelm@53983
  2243
   linear_continuum_topology.  Allows to generalize theorems about
wenzelm@53983
  2244
   limits and order.  Instances are reals and extended reals.
hoelzl@51732
  2245
hoelzl@51732
  2246
 - continuous and continuos_on from Multivariate_Analysis:
wenzelm@53983
  2247
   "continuous" is the continuity of a function at a filter.  "isCont"
wenzelm@53983
  2248
   is now an abbrevitation: "isCont x f == continuous (at _) f".
wenzelm@53983
  2249
wenzelm@53983
  2250
   Generalized continuity lemmas from isCont to continuous on an
wenzelm@53983
  2251
   arbitrary filter.
wenzelm@53983
  2252
wenzelm@53983
  2253
 - compact from Multivariate_Analysis. Use Bolzano's lemma to prove
wenzelm@53983
  2254
   compactness of closed intervals on reals. Continuous functions
wenzelm@53983
  2255
   attain infimum and supremum on compact sets. The inverse of a
wenzelm@53983
  2256
   continuous function is continuous, when the function is continuous
wenzelm@53983
  2257
   on a compact set.
hoelzl@51732
  2258
hoelzl@51732
  2259
 - connected from Multivariate_Analysis. Use it to prove the
hoelzl@51775
  2260
   intermediate value theorem. Show connectedness of intervals on
hoelzl@51775
  2261
   linear_continuum_topology).
hoelzl@51732
  2262
hoelzl@51732
  2263
 - first_countable_topology from Multivariate_Analysis. Is used to
wenzelm@53983
  2264
   show equivalence of properties on the neighbourhood filter of x and
wenzelm@53983
  2265
   on all sequences converging to x.
wenzelm@53983
  2266
wenzelm@53983
  2267
 - FDERIV: Definition of has_derivative moved to Deriv.thy. Moved
wenzelm@53983
  2268
   theorems from Library/FDERIV.thy to Deriv.thy and base the
wenzelm@53983
  2269
   definition of DERIV on FDERIV. Add variants of DERIV and FDERIV
wenzelm@53983
  2270
   which are restricted to sets, i.e. to represent derivatives from
wenzelm@53983
  2271
   left or right.
hoelzl@51732
  2272
hoelzl@51732
  2273
 - Removed the within-filter. It is replaced by the principal filter:
hoelzl@51732
  2274
hoelzl@51732
  2275
     F within X = inf F (principal X)
hoelzl@51732
  2276
hoelzl@51732
  2277
 - Introduce "at x within U" as a single constant, "at x" is now an
hoelzl@51732
  2278
   abbreviation for "at x within UNIV"
hoelzl@51732
  2279
wenzelm@53983
  2280
 - Introduce named theorem collections tendsto_intros,
wenzelm@53983
  2281
   continuous_intros, continuous_on_intros and FDERIV_intros. Theorems
wenzelm@53983
  2282
   in tendsto_intros (or FDERIV_intros) are also available as
wenzelm@53983
  2283
   tendsto_eq_intros (or FDERIV_eq_intros) where the right-hand side
wenzelm@53983
  2284
   is replaced by a congruence rule. This allows to apply them as
wenzelm@53983
  2285
   intro rules and then proving equivalence by the simplifier.
hoelzl@51732
  2286
hoelzl@51732
  2287
 - Restructured theories in HOL-Complex_Main:
hoelzl@51732
  2288
hoelzl@51732
  2289
   + Moved RealDef and RComplete into Real
hoelzl@51732
  2290
hoelzl@51732
  2291
   + Introduced Topological_Spaces and moved theorems about
hoelzl@51732
  2292
     topological spaces, filters, limits and continuity to it
hoelzl@51732
  2293
hoelzl@51732
  2294
   + Renamed RealVector to Real_Vector_Spaces
hoelzl@51732
  2295
wenzelm@53983
  2296
   + Split Lim, SEQ, Series into Topological_Spaces,
wenzelm@53983
  2297
     Real_Vector_Spaces, and Limits
hoelzl@51732
  2298
hoelzl@51732
  2299
   + Moved Ln and Log to Transcendental
hoelzl@51732
  2300
hoelzl@51732
  2301
   + Moved theorems about continuity from Deriv to Topological_Spaces
hoelzl@51732
  2302
hoelzl@51732
  2303
 - Remove various auxiliary lemmas.

blanchet@55889
  2316
  - Better support for "isar_proofs".
blanchet@55889
  2317
  - MaSh has been fined-tuned and now runs as a local server.
blanchet@51137
  2318
wenzelm@54032
  2319
* Improved support for ad hoc overloading of constants (see also

wenzelm@54032
  2321
wenzelm@54032
  2322
* Library/Polynomial.thy:
wenzelm@54032
  2323
  - Use lifting for primitive definitions.
wenzelm@54032
  2324
  - Explicit conversions from and to lists of coefficients, used for
wenzelm@54032
  2325
    generated code.
wenzelm@54032
  2326
  - Replaced recursion operator poly_rec by fold_coeffs.
wenzelm@54032
  2327
  - Prefer pre-existing gcd operation for gcd.
wenzelm@54032
  2328
  - Fact renames:

wenzelm@54032
  2334
* New Library/Simps_Case_Conv.thy: Provides commands simps_of_case and
wenzelm@54032
  2335
case_of_simps to convert function definitions between a list of
wenzelm@54032
  2336
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
  2338
wenzelm@54032

  2340
sets defined by Lifting/Transfer.
wenzelm@54032
  2341
wenzelm@54032

* Discontinued theory src/HOL/Library/Eval_Witness.  INCOMPATIBILITY.
wenzelm@54032
  2343
wenzelm@54032

  2355
* HOL-Algebra: Discontinued theories ~~/src/HOL/Algebra/abstract and
wenzelm@53983
  2356
~~/src/HOL/Algebra/poly.  Existing theories should be based on
wenzelm@53983

wenzelm@54032
  2362
    new commands "primrec_new", "primcorec", and
wenzelm@54032
  2363
    "datatype_new_compat", as well as documentation. See

    coinduct).
wenzelm@54032
  2367
  - Renamed keywords:

* Spec_Check is a Quickcheck tool for Isabelle/ML.  The ML function
wenzelm@53971
  2384
"check_property" allows to check specifications of the form "ALL x y
wenzelm@53971
  2385
z. prop x y z".  See also ~~/src/Tools/Spec_Check/ with its

wenzelm@53971
  2387
wenzelm@53709
  2388
* Improved printing of exception trace in Poly/ML 5.5.1, with regular
wenzelm@53709
  2389
tracing output in the command transaction context instead of physical
wenzelm@53709
  2390

  2393
* ML type "theory" is now immutable, without any special treatment of
wenzelm@53971
  2394
drafts or linear updates (which could lead to "stale theory" errors in
wenzelm@53971
  2395
the past).  Discontinued obsolete operations like Theory.copy,
wenzelm@53971

  2397
INCOMPATIBILITY.
wenzelm@53164
  2398
wenzelm@51551

wenzelm@51551
  2401
    Skip_Proof.prove  ~>  Goal.prove_sorry

  2404
Minor INCOMPATIBILITY.
wenzelm@51703
  2405
wenzelm@51717
  2406
* Simplifier tactics and tools use proper Proof.context instead of
wenzelm@51717
  2407
historic type simpset.  Old-style declarations like addsimps,
wenzelm@51717
  2408
addsimprocs etc. operate directly on Proof.context.  Raw type simpset
wenzelm@51717
  2409
retains its use as snapshot of the main Simplifier context, using
wenzelm@51717
  2410
simpset_of and put_simpset on Proof.context.  INCOMPATIBILITY -- port
wenzelm@51717
  2411
old tools by making them depend on (ctxt : Proof.context) instead of
wenzelm@51717
  2412
(ss : simpset), then turn (simpset_of ctxt) into ctxt.
wenzelm@51717
  2413
wenzelm@53971
  2414
* Modifiers for classical wrappers (e.g. addWrapper, delWrapper)
wenzelm@53971
  2415
operate on Proof.context instead of claset, for uniformity with addIs,
wenzelm@53971
  2416
addEs, addDs etc. Note that claset_of and put_claset allow to manage
wenzelm@53971
  2417
clasets separately from the context.
wenzelm@53971
  2418
wenzelm@51717
  2419
* Discontinued obsolete ML antiquotations @{claset} and @{simpset}.

INCOMPATIBILITY, use @{context} instead.
wenzelm@51717
  2421
wenzelm@53971

wenzelm@52743
  2440
wenzelm@52053
  2441

wenzelm@52116
  2446
wenzelm@52439
  2447
* Improved "isabelle keywords" tool (for old-style ProofGeneral
wenzelm@52439
  2448
keyword tables): use Isabelle/Scala operations, which inspect outer

  2449
syntax without requiring to build sessions first.
wenzelm@52439
  2450
wenzelm@53971
  2451
* Sessions may be organized via 'chapter' specifications in the ROOT
wenzelm@53971

wenzelm@53971
  2453
tree-like organization via implicit sub-session relation (with its
wenzelm@53971
  2454
tendency towards erratic fluctuation of URLs) has been discontinued.

*** General ***
wenzelm@47967
  2464
wenzelm@50126
  2465
* Theorem status about oracles and unfinished/failed future proofs is
wenzelm@50126
  2466
no longer printed by default, since it is incompatible with
wenzelm@50126
  2467
incremental / parallel checking of the persistent document model.  ML
wenzelm@50126
  2468
function Thm.peek_status may be used to inspect a snapshot of the
wenzelm@50126
  2469
ongoing evaluation process.  Note that in batch mode --- notably
wenzelm@50126
  2470
isabelle build --- the system ensures that future proofs of all
wenzelm@50126
  2471
accessible theorems in the theory context are finished (as before).
wenzelm@50126
  2472
wenzelm@49699
  2473
* Configuration option show_markup controls direct inlining of markup
wenzelm@49699
  2474
into the printed representation of formal entities --- notably type
wenzelm@49699
  2475
and sort constraints.  This enables Prover IDE users to retrieve that
wenzelm@49699
  2476
information via tooltips in the output window, for example.
wenzelm@49699
  2477
wenzelm@48890
  2478
* Command 'ML_file' evaluates ML text from a file directly within the
wenzelm@48890
  2479
theory, without any predeclaration via 'uses' in the theory header.
wenzelm@48890
  2480
wenzelm@49243
  2481
* Old command 'use' command and corresponding keyword 'uses' in the
wenzelm@49243
  2482
theory header are legacy features and will be discontinued soon.
wenzelm@49243
  2483
Tools that load their additional source files may imitate the
wenzelm@49243
  2484
'ML_file' implementation, such that the system can take care of
wenzelm@49243
  2485
dependencies properly.
wenzelm@49243
  2486
wenzelm@47967
  2487
* Discontinued obsolete method fastsimp / tactic fast_simp_tac, which
wenzelm@47967
  2488
is called fastforce / fast_force_tac already since Isabelle2011-1.
wenzelm@47967
  2489
wenzelm@50110
  2490
* Updated and extended "isar-ref" and "implementation" manual, reduced
wenzelm@50110
  2491
remaining material in old "ref" manual.
wenzelm@48120
  2492
wenzelm@51050
  2493
* Improved support for auxiliary contexts that indicate block structure
wenzelm@51050
  2494
for specifications.  Nesting of "context fixes ... context assumes ..."
wenzelm@49841
  2495
and "class ... context ...".
wenzelm@49841
  2496
wenzelm@50772
  2497
* Attribute "consumes" allows a negative value as well, which is
wenzelm@50778
  2498
interpreted relatively to the total number of premises of the rule in
wenzelm@50772
  2499
the target context.  This form of declaration is stable when exported
wenzelm@50772
  2500
from a nested 'context' with additional assumptions.  It is the
wenzelm@50772
  2501
preferred form for definitional packages, notably cases/rules produced
wenzelm@50772
  2502
in HOL/inductive and HOL/function.
wenzelm@50772
  2503
wenzelm@49869
  2504
* More informative error messages for Isar proof commands involving
wenzelm@49869
  2505
lazy enumerations (method applications etc.).
wenzelm@49869
  2506
wenzelm@50213
  2507
* Refined 'help' command to retrieve outer syntax commands according
wenzelm@50213
  2508
to name patterns (with clickable results).

*** Prover IDE -- Isabelle/Scala/jEdit ***
wenzelm@49968
  2512
wenzelm@49968
  2513
* Parallel terminal proofs ('by') are enabled by default, likewise
wenzelm@49968
  2514
proofs that are built into packages like 'datatype', 'function'.  This
wenzelm@49968
  2515
allows to "run ahead" checking the theory specifications on the
wenzelm@49968
  2516
surface, while the prover is still crunching on internal
wenzelm@49968
  2517
justifications.  Unfinished / cancelled proofs are restarted as
wenzelm@49968
  2518
required to complete full proof checking eventually.
wenzelm@49968
  2519
wenzelm@49968
  2520
* Improved output panel with tooltips, hyperlinks etc. based on the
wenzelm@49968
  2521
same Rich_Text_Area as regular Isabelle/jEdit buffers.  Activation of
wenzelm@49968
  2522
tooltips leads to some window that supports the same recursively,
wenzelm@49968
  2523
which can lead to stacks of tooltips as the semantic document content
wenzelm@49968
  2524
is explored.  ESCAPE closes the whole stack, individual windows may be
wenzelm@49968
  2525
closed separately, or detached to become independent jEdit dockables.
wenzelm@49968
  2526
wenzelm@50717
  2527
* Improved support for commands that produce graph output: the text
wenzelm@50717
  2528
message contains a clickable area to open a new instance of the graph
wenzelm@50717
  2529
browser on demand.
wenzelm@50717
  2530
wenzelm@49968
  2531
* More robust incremental parsing of outer syntax (partial comments,
wenzelm@49968
  2532
malformed symbols).  Changing the balance of open/close quotes and
wenzelm@49968
  2533
comment delimiters works more conveniently with unfinished situations
wenzelm@49968
  2534
that frequently occur in user interaction.
wenzelm@49968
  2535
wenzelm@49968
  2536
* More efficient painting and improved reactivity when editing large
wenzelm@49968
  2537
files.  More scalable management of formal document content.
wenzelm@49968
  2538
wenzelm@50505
  2539
* Smarter handling of tracing messages: prover process pauses after
wenzelm@50505
  2540
certain number of messages per command transaction, with some user
wenzelm@50505
  2541
dialog to stop or continue.  This avoids swamping the front-end with
wenzelm@50119
  2542
potentially infinite message streams.
wenzelm@49968
  2543
wenzelm@49968
  2544
* More plugin options and preferences, based on Isabelle/Scala.  The
wenzelm@49968
  2545
jEdit plugin option panel provides access to some Isabelle/Scala
wenzelm@49968
  2546
options, including tuning parameters for editor reactivity and color
wenzelm@49968
  2547
schemes.
wenzelm@49968
  2548
wenzelm@50184
  2549
* Dockable window "Symbols" provides some editing support for Isabelle
wenzelm@50184
  2550
symbols.
wenzelm@50184
  2551
wenzelm@51082
  2552
* Dockable window "Monitor" shows ML runtime statistics.  Note that
wenzelm@51082
  2553
continuous display of the chart slows down the system.
wenzelm@50701
  2554
wenzelm@50183
  2555
* Improved editing support for control styles: subscript, superscript,
wenzelm@50183
  2556
bold, reset of style -- operating on single symbols or text
wenzelm@50198
  2557
selections.  Cf. keyboard shortcuts C+e DOWN/UP/RIGHT/LEFT.
wenzelm@50198
  2558
wenzelm@50198
  2559
* Actions isabelle.increase-font-size and isabelle.decrease-font-size
wenzelm@50198
  2560
adjust the main text area font size, and its derivatives for output,
wenzelm@50836
  2561
tooltips etc.  Cf. keyboard shortcuts C-PLUS and C-MINUS, which often
wenzelm@50836
  2562
need to be adapted to local keyboard layouts.
wenzelm@50183
  2563
wenzelm@50730
  2564
* More reactive completion popup by default: use \t (TAB) instead of
wenzelm@50730
  2565
\n (NEWLINE) to minimize intrusion into regular flow of editing.  See
wenzelm@50730
  2566
also "Plugin Options / SideKick / General / Code Completion Options".
wenzelm@50730
  2567
wenzelm@50406
  2568
* Implicit check and build dialog of the specified logic session
wenzelm@50406
  2569
image.  For example, HOL, HOLCF, HOL-Nominal can be produced on
wenzelm@50406
  2570
demand, without bundling big platform-dependent heap images in the
wenzelm@50406
  2571
Isabelle distribution.
wenzelm@50406
  2572
wenzelm@49968
  2573
* Uniform Java 7 platform on Linux, Mac OS X, Windows: recent updates
wenzelm@49968
  2574
from Oracle provide better multi-platform experience.  This version is
wenzelm@49968
  2575
now bundled exclusively with Isabelle.

  2581
Haskell Prelude to a small set of fundamental operations.
haftmann@48431
  2582
wenzelm@50646
  2583
* Command 'export_code': relative file names are interpreted
wenzelm@50646
  2584
relatively to master directory of current theory rather than the
wenzelm@50646
  2585
rather arbitrary current working directory.  INCOMPATIBILITY.
haftmann@48371
  2586
wenzelm@48205
  2587
* Discontinued obsolete attribute "COMP".  Potential INCOMPATIBILITY,
wenzelm@48205
  2588
use regular rule composition via "OF" / "THEN", or explicit proof
wenzelm@48205
  2589
structure instead.  Note that Isabelle/ML provides a variety of
wenzelm@48205
  2590
operators like COMP, INCR_COMP, COMP_INCR, which need to be applied
wenzelm@48205
  2591
with some care where this is really required.
wenzelm@48205
  2592
wenzelm@48792
  2593
* Command 'typ' supports an additional variant with explicit sort
wenzelm@48792
  2594
constraint, to infer and check the most general type conforming to a
wenzelm@51063
  2595
given sort.  Example (in HOL):
wenzelm@48792
  2596
wenzelm@48792
  2597
  typ "_ * _ * bool * unit" :: finite
wenzelm@48792

haftmann@49948
  2641
wenzelm@49836
  2642
* Simplified 'typedef' specifications: historical options for implicit
wenzelm@49836
  2643
set definition and alternative name have been discontinued.  The
wenzelm@49836
  2644
former behavior of "typedef (open) t = A" is now the default, but
wenzelm@49836
  2645
written just "typedef t = A".  INCOMPATIBILITY, need to adapt theories
wenzelm@49836
  2646
accordingly.
wenzelm@49836
  2647
wenzelm@50646
  2648
* Removed constant "chars"; prefer "Enum.enum" on type "char"
wenzelm@50646
  2649
directly.  INCOMPATIBILITY.
wenzelm@50646
  2650
wenzelm@50646
  2651
* Moved operation product, sublists and n_lists from theory Enum to
wenzelm@50646
  2652
List.  INCOMPATIBILITY.
haftmann@49822
  2653
haftmann@49739
  2654
* Theorem UN_o generalized to SUP_comp.  INCOMPATIBILITY.
haftmann@49739
  2655
haftmann@49738
  2656
* Class "comm_monoid_diff" formalises properties of bounded
haftmann@49388
  2657
subtraction, with natural numbers and multisets as typical instances.
haftmann@49388
  2658
wenzelm@50646
  2659
* Added combinator "Option.these" with type "'a option set => 'a set".
wenzelm@50646
  2660
wenzelm@50646
  2661
* Theory "Transitive_Closure": renamed lemmas

wenzelm@50646
  2669
wenzelm@50646
  2670
  left_distrib ~> distrib_right

wenzelm@50646
  2674
wenzelm@50646
  2675
* Generalized the definition of limits:
wenzelm@50646
  2676
wenzelm@50646
  2677
  - Introduced the predicate filterlim (LIM x F. f x :> G) which
wenzelm@50646
  2678
    expresses that when the input values x converge to F then the
wenzelm@50646
  2679
    output f x converges to G.
wenzelm@50646
  2680
wenzelm@50646
  2681
  - Added filters for convergence to positive (at_top) and negative
wenzelm@50646
  2682
    infinity (at_bot).
wenzelm@50646
  2683
wenzelm@50646
  2684
  - Moved infinity in the norm (at_infinity) from
wenzelm@50646
  2685
    Multivariate_Analysis to Complex_Main.
wenzelm@50646
  2686
wenzelm@50646
  2687
  - Removed real_tendsto_inf, it is superseded by "LIM x F. f x :>
wenzelm@50646
  2688
    at_top".

wenzelm@50646
  2691
wenzelm@50646
  2692
* Theory "Library/Option_ord" provides instantiation of option type to
wenzelm@50646
  2693
lattice type classes.
wenzelm@50646
  2694
wenzelm@50646
  2695
* Theory "Library/Multiset": renamed
wenzelm@50646
  2696
wenzelm@50646
  2697
    constant fold_mset ~> Multiset.fold
wenzelm@50646

    fact fold_mset_commute ~> fold_mset_comm
wenzelm@50646

wenzelm@50646
  2700
INCOMPATIBILITY.
wenzelm@50646
  2701
wenzelm@50646
  2702
* Renamed theory Library/List_Prefix to Library/Sublist, with related
wenzelm@50646
  2703
changes as follows.
wenzelm@50646
  2704
wenzelm@50646
  2705
  - Renamed constants (and related lemmas)
Christian@49145
  2706
Christian@49145
  2707
      prefix ~> prefixeq
Christian@49145
  2708
      strict_prefix ~> prefix
Christian@49145
  2709
wenzelm@50646
  2710
  - Replaced constant "postfix" by "suffixeq" with swapped argument
wenzelm@50646
  2711
    order (i.e., "postfix xs ys" is now "suffixeq ys xs") and dropped
wenzelm@50646
  2712
    old infix syntax "xs >>= ys"; use "suffixeq ys xs" instead.
wenzelm@50646
  2713
    Renamed lemmas accordingly.
wenzelm@50646
  2714
wenzelm@50646
  2715
  - Added constant "list_hembeq" for homeomorphic embedding on
wenzelm@50646
  2716
    lists. Added abbreviation "sublisteq" for special case
wenzelm@50646
  2717
    "list_hembeq (op =)".
wenzelm@50646
  2718
wenzelm@50646
  2719
  - Theory Library/Sublist no longer provides "order" and "bot" type
wenzelm@50646
  2720
    class instances for the prefix order (merely corresponding locale
wenzelm@50646
  2721
    interpretations). The type class instances are now in theory
wenzelm@50646
  2722
    Library/Prefix_Order.
wenzelm@50646
  2723
wenzelm@50646
  2724
  - The sublist relation of theory Library/Sublist_Order is now based
wenzelm@50646
  2725
    on "Sublist.sublisteq".  Renamed lemmas accordingly:
Christian@50516
  2726
Christian@50516
  2727
      le_list_append_le_same_iff ~> Sublist.sublisteq_append_le_same_iff

      le_list_Cons_EX ~> Sublist.list_hembeq_ConsD
Christian@50516
  2731
      le_list_drop_Cons2 ~> Sublist.sublisteq_Cons2'
Christian@50516
  2732
      le_list_drop_Cons_neq ~> Sublist.sublisteq_Cons2_neq
