*** General ***
wenzelm@57941
     8
wenzelm@57941
     9
* Commands 'method_setup' and 'attribute_setup' now work within a
wenzelm@57941
    10
local theory context.
wenzelm@57941
    11
wenzelm@57946
    12
* Command 'named_theorems' declares a dynamic fact within the context,
wenzelm@57946
    13
together with an attribute to maintain the content incrementally.
wenzelm@57946
    14
This supersedes functor Named_Thms, but with a subtle change of
wenzelm@57946
    15
semantics due to external visual order vs. internal reverse order.

haftmann@58100
    20
* Command and antiquotation "value" provide different evaluation slots (again),
haftmann@58100
    21
where the previous strategy (nbe after ML) serves as default.
haftmann@58100
    22
Minor INCOMPATIBILITY.
haftmann@58100
    23
blanchet@57983
    24
* New (co)datatype package:
blanchet@57983
    25
  - Renamed theorems:
blanchet@57983
    26
      disc_corec ~> corec_disc
blanchet@57983
    27
      disc_corec_iff ~> corec_disc_iff
blanchet@57983
    28
      disc_exclude ~> distinct_disc
blanchet@57983
    29
      disc_exhaust ~> exhaust_disc
blanchet@57983
    30
      disc_map_iff ~> map_disc_iff
blanchet@57983
    31
      sel_corec ~> corec_sel
blanchet@57983
    32
      sel_exhaust ~> exhaust_sel
blanchet@57983
    33
      sel_map ~> map_sel
blanchet@57983
    34
      sel_set ~> set_sel
blanchet@57983
    35
      sel_split ~> split_sel
blanchet@57983
    36
      sel_split_asm ~> split_sel_asm
blanchet@57983
    37
      strong_coinduct ~> coinduct_strong
blanchet@57983
    38
      weak_case_cong ~> case_cong_weak
blanchet@57983
    39
    INCOMPATIBILITY.
blanchet@58192
    40
  - The "no_code" option to "free_constructors", "datatype_new", and
blanchet@58192
    41
    "codatatype" has been renamed "plugins del: code".
blanchet@58192
    42
    INCOMPATIBILITY.
blanchet@58044
    43
  - The rules "set_empty" have been removed. They are easy
blanchet@58044
    44
    consequences of other set rules "by auto".
blanchet@58044
    45
    INCOMPATIBILITY.
blanchet@58044
    46
  - The rule "set_cases" is now registered with the "[cases set]"
blanchet@57990
    47
    attribute. This can influence the behavior of the "cases" proof
blanchet@57990
    48
    method when more than one case rule is applicable (e.g., an
blanchet@57990
    49
    assumption is of the form "w : set ws" and the method "cases w"
blanchet@57990
    50
    is invoked). The solution is to specify the case rule explicitly
blanchet@57990
    51
    (e.g. "cases w rule: widget.exhaust").
blanchet@57990
    52
    INCOMPATIBILITY.
blanchet@57983
    53
blanchet@57983
    54
* Old datatype package:
blanchet@57983
    55
  - Renamed theorems:
blanchet@57983
    56
      weak_case_cong ~> case_cong_weak
blanchet@57983
    57
    INCOMPATIBILITY.
blanchet@57983
    58
blanchet@57737
    59
* Sledgehammer:
blanchet@57737
    60
  - Minimization is now always enabled by default.
blanchet@57737
    61
    Removed subcommand:
blanchet@57737
    62
      min
blanchet@57737
    63
blanchet@58062
    64
* Old and new SMT modules:
blanchet@58067
    65
  - The old 'smt' method has been renamed 'old_smt' and moved to
blanchet@58060
    66
    'src/HOL/Library/Old_SMT.thy'. It provided for compatibility, until
blanchet@58067
    67
    applications have been ported to use the new 'smt' method. For the
blanchet@58067
    68
    method to work, an older version of Z3 (e.g. Z3 3.2 or 4.0) must be
blanchet@58062
    69
    installed, and the environment variable "OLD_Z3_SOLVER" must point to
blanchet@58062
    70
    it.
blanchet@58062
    71
    INCOMPATIBILITY.
blanchet@58067
    72
  - The 'smt2' method has been renamed 'smt'.
blanchet@58060
    73
    INCOMPATIBILITY.

blanchet@58066
    76
*** ML ***
blanchet@58066
    77
blanchet@58066
    78
* Tactical PARALLEL_ALLGOALS is the most common way to refer to
blanchet@58066
    79
PARALLEL_GOALS.

wenzelm@57452
    83
New in Isabelle2014 (August 2014)
wenzelm@57452
    84
---------------------------------
wenzelm@54055
    85
wenzelm@54702
    86
*** General ***
wenzelm@54702
    87
wenzelm@57452
    88
* Support for official Standard ML within the Isabelle context.
wenzelm@57452
    89
Command 'SML_file' reads and evaluates the given Standard ML file.
wenzelm@57452
    90
Toplevel bindings are stored within the theory context; the initial
wenzelm@57452
    91
environment is restricted to the Standard ML implementation of
wenzelm@57452
    92
Poly/ML, without the add-ons of Isabelle/ML.  Commands 'SML_import'
wenzelm@57452
    93
and 'SML_export' allow to exchange toplevel bindings between the two
wenzelm@57452
    94
separate environments.  See also ~~/src/Tools/SML/Examples.thy for
wenzelm@57452
    95
some examples.
wenzelm@56499
    96
wenzelm@57504
    97
* Standard tactics and proof methods such as "clarsimp", "auto" and
wenzelm@57504
    98
"safe" now preserve equality hypotheses "x = expr" where x is a free
wenzelm@57504
    99
variable.  Locale assumptions and chained facts containing "x"
wenzelm@57504
   100
continue to be useful.  The new method "hypsubst_thin" and the
wenzelm@57504
   101
configuration option "hypsubst_thin" (within the attribute name space)
wenzelm@57504
   102
restore the previous behavior.  INCOMPATIBILITY, especially where
wenzelm@57504
   103
induction is done after these methods or when the names of free and
wenzelm@57504
   104
bound variables clash.  As first approximation, old proofs may be
wenzelm@57504
   105
repaired by "using [[hypsubst_thin = true]]" in the critical spot.
wenzelm@57504
   106
wenzelm@56232
   107
* More static checking of proof methods, which allows the system to
wenzelm@56232
   108
form a closure over the concrete syntax.  Method arguments should be
wenzelm@56232
   109
processed in the original proof context as far as possible, before
wenzelm@56232
   110
operating on the goal state.  In any case, the standard discipline for
wenzelm@56232
   111
subgoal-addressing needs to be observed: no subgoals or a subgoal
wenzelm@56232
   112
number that is out of range produces an empty result sequence, not an
wenzelm@56232
   113
exception.  Potential INCOMPATIBILITY for non-conformant tactical
wenzelm@56232
   114
proof tools.
wenzelm@56232
   115
wenzelm@57452
   116
* Lexical syntax (inner and outer) supports text cartouches with
wenzelm@57452
   117
arbitrary nesting, and without escapes of quotes etc.  The Prover IDE
wenzelm@57452
   118
supports input via ` (backquote).
wenzelm@57452
   119
wenzelm@57452
   120
* The outer syntax categories "text" (for formal comments and document
wenzelm@57452
   121
markup commands) and "altstring" (for literal fact references) allow
wenzelm@57452
   122
cartouches as well, in addition to the traditional mix of quotations.
wenzelm@57452
   123
wenzelm@57452
   124
* Syntax of document antiquotation @{rail} now uses \<newline> instead
wenzelm@57452
   125
of "\\", to avoid the optical illusion of escaped backslash within
wenzelm@57491
   126
string token.  General renovation of its syntax using text cartouches.
wenzelm@57452
   127
Minor INCOMPATIBILITY.
wenzelm@57452
   128
wenzelm@57452
   129
* Discontinued legacy_isub_isup, which was a temporary workaround for
wenzelm@57452
   130
Isabelle/ML in Isabelle2013-1.  The prover process no longer accepts
wenzelm@57452
   131
old identifier syntax with \<^isub> or \<^isup>.  Potential
wenzelm@57452
   132
INCOMPATIBILITY.
wenzelm@57452
   133
wenzelm@57452
   134
* Document antiquotation @{url} produces markup for the given URL,
wenzelm@57452
   135
which results in an active hyperlink within the text.
wenzelm@57452
   136
wenzelm@57452
   137
* Document antiquotation @{file_unchecked} is like @{file}, but does
wenzelm@57452
   138
not check existence within the file-system.
wenzelm@57452
   139
wenzelm@57452
   140
* Updated and extended manuals: codegen, datatypes, implementation,
wenzelm@57452
   141
isar-ref, jedit, system.
wenzelm@57423
   142
wenzelm@54702
   143
wenzelm@54533
   144
*** Prover IDE -- Isabelle/Scala/jEdit ***
wenzelm@54533
   145
wenzelm@57650
   146
* Improved Document panel: simplified interaction where every single
wenzelm@57452
   147
mouse click (re)opens document via desktop environment or as jEdit
wenzelm@57452
   148
buffer.
wenzelm@57452
   149
wenzelm@57452
   150
* Support for Navigator plugin (with toolbar buttons), with connection
wenzelm@57452
   151
to PIDE hyperlinks.
wenzelm@57452
   152
wenzelm@57452
   153
* Auxiliary files ('ML_file' etc.) are managed by the Prover IDE.
wenzelm@57452
   154
Open text buffers take precedence over copies within the file-system.
wenzelm@57452
   155
wenzelm@57452
   156
* Improved support for Isabelle/ML, with jEdit mode "isabelle-ml" for
wenzelm@57452
   157
auxiliary ML files.
wenzelm@57423
   158
wenzelm@57423
   159
* Improved syntactic and semantic completion mechanism, with simple
wenzelm@57423
   160
templates, completion language context, name-space completion,
wenzelm@57423
   161
file-name completion, spell-checker completion.
wenzelm@57423
   162
wenzelm@57423
   163
* Refined GUI popup for completion: more robust key/mouse event
wenzelm@57423
   164
handling and propagation to enclosing text area -- avoid loosing
wenzelm@57423
   165
keystrokes with slow / remote graphics displays.
wenzelm@57423
   166
wenzelm@57833
   167
* Completion popup supports both ENTER and TAB (default) to select an
wenzelm@57833
   168
item, depending on Isabelle options.
wenzelm@57833
   169
wenzelm@57423
   170
* Refined insertion of completion items wrt. jEdit text: multiple
wenzelm@57423
   171
selections, rectangular selections, rectangular selection as "tall
wenzelm@57423
   172
caret".
wenzelm@56342
   173
wenzelm@56580
   174
* Integrated spell-checker for document text, comments etc. with
wenzelm@57423
   175
completion popup and context-menu.
wenzelm@56554
   176
wenzelm@56879
   177
* More general "Query" panel supersedes "Find" panel, with GUI access
wenzelm@56879
   178
to commands 'find_theorems' and 'find_consts', as well as print
wenzelm@56879
   179
operations for the context.  Minor incompatibility in keyboard
wenzelm@56879
   180
shortcuts etc.: replace action isabelle-find by isabelle-query.
wenzelm@56761
   181
wenzelm@56901
   182
* Search field for all output panels ("Output", "Query", "Info" etc.)
wenzelm@56901
   183
to highlight text via regular expression.
wenzelm@56901
   184
wenzelm@54881
   185
* Option "jedit_print_mode" (see also "Plugin Options / Isabelle /
wenzelm@54881
   186
General") allows to specify additional print modes for the prover
wenzelm@54881
   187
process, without requiring old-fashioned command-line invocation of
wenzelm@54881
   188
"isabelle jedit -m MODE".
wenzelm@54881
   189
wenzelm@56505
   190
* More support for remote files (e.g. http) using standard Java
wenzelm@56505
   191
networking operations instead of jEdit virtual file-systems.
wenzelm@56505
   192
wenzelm@57822
   193
* Empty editors buffers that are no longer required (e.g.\ via theory
wenzelm@57822
   194
imports) are automatically removed from the document model.
wenzelm@57822
   195
wenzelm@57869
   196
* Improved monitor panel.
wenzelm@57869
   197
wenzelm@56838
   198
* Improved Console/Scala plugin: more uniform scala.Console output,
wenzelm@56838
   199
more robust treatment of threads and interrupts.
wenzelm@56838
   200
wenzelm@56939
   201
* Improved management of dockable windows: clarified keyboard focus
wenzelm@56939
   202
and window placement wrt. main editor view; optional menu item to
wenzelm@56939
   203
"Detach" a copy where this makes sense.
wenzelm@56939
   204
wenzelm@57452
   205
* New Simplifier Trace panel provides an interactive view of the
wenzelm@57591
   206
simplification process, enabled by the "simp_trace_new" attribute
wenzelm@57452
   207
within the context.
wenzelm@57452
   208
wenzelm@57452
   209
wenzelm@55001
   210
*** Pure ***
wenzelm@55001
   211
wenzelm@57504
   212
* Low-level type-class commands 'classes', 'classrel', 'arities' have
wenzelm@57504
   213
been discontinued to avoid the danger of non-trivial axiomatization
wenzelm@57504
   214
that is not immediately visible.  INCOMPATIBILITY, use regular
wenzelm@57504
   215
'instance' command with proof.  The required OFCLASS(...) theorem
wenzelm@57504
   216
might be postulated via 'axiomatization' beforehand, or the proof
wenzelm@57504
   217
finished trivially if the underlying class definition is made vacuous
wenzelm@57504
   218
(without any assumptions).  See also Isabelle/ML operations
wenzelm@57504
   219
Axclass.class_axiomatization, Axclass.classrel_axiomatization,
wenzelm@57504
   220
Axclass.arity_axiomatization.
wenzelm@57504
   221
wenzelm@56245
   222
* Basic constants of Pure use more conventional names and are always
wenzelm@56245
   223
qualified.  Rare INCOMPATIBILITY, but with potentially serious
wenzelm@56245
   224
consequences, notably for tools in Isabelle/ML.  The following
wenzelm@56245
   225
renaming needs to be applied:
wenzelm@56245
   226
wenzelm@56245
   227
  ==             ~>  Pure.eq
wenzelm@56245
   228
  ==>            ~>  Pure.imp
wenzelm@56245
   229
  all            ~>  Pure.all
wenzelm@56245
   230
  TYPE           ~>  Pure.type
wenzelm@56245
   231
  dummy_pattern  ~>  Pure.dummy_pattern
wenzelm@56245
   232
wenzelm@56245
   233
Systematic porting works by using the following theory setup on a
wenzelm@56245
   234
*previous* Isabelle version to introduce the new name accesses for the
wenzelm@56245
   235
old constants:
wenzelm@56245
   236
wenzelm@56245
   237
setup {*
wenzelm@56245
   238
  fn thy => thy
wenzelm@56245
   239
    |> Sign.root_path
wenzelm@56245
   240
    |> Sign.const_alias (Binding.qualify true "Pure" @{binding eq}) "=="
wenzelm@56245
   241
    |> Sign.const_alias (Binding.qualify true "Pure" @{binding imp}) "==>"
wenzelm@56245
   242
    |> Sign.const_alias (Binding.qualify true "Pure" @{binding all}) "all"
wenzelm@56245
   243
    |> Sign.restore_naming thy
wenzelm@56245
   244
*}
wenzelm@56245
   245
wenzelm@56245
   246
Thus ML antiquotations like @{const_name Pure.eq} may be used already.
wenzelm@56245
   247
Later the application is moved to the current Isabelle version, and
wenzelm@56245
   248
the auxiliary aliases are deleted.
wenzelm@56245
   249
wenzelm@55143
   250
* Attributes "where" and "of" allow an optional context of local
wenzelm@55143
   251
variables ('for' declaration): these variables become schematic in the
wenzelm@55143
   252
instantiated theorem.
wenzelm@55143
   253
wenzelm@55152
   254
* Obsolete attribute "standard" has been discontinued (legacy since
wenzelm@55152
   255
Isabelle2012).  Potential INCOMPATIBILITY, use explicit 'for' context
wenzelm@55152
   256
where instantiations with schematic variables are intended (for
wenzelm@55152
   257
declaration commands like 'lemmas' or attributes like "of").  The
wenzelm@55152
   258
following temporary definition may help to port old applications:
wenzelm@55152
   259
wenzelm@55152
   260
  attribute_setup standard =
wenzelm@55152
   261
    "Scan.succeed (Thm.rule_attribute (K Drule.export_without_context))"
wenzelm@55152
   262
wenzelm@55001
   263
* More thorough check of proof context for goal statements and
wenzelm@55006
   264
attributed fact expressions (concerning background theory, declared
wenzelm@55006
   265
hyps).  Potential INCOMPATIBILITY, tools need to observe standard
wenzelm@55006
   266
context discipline.  See also Assumption.add_assumes and the more
wenzelm@55006
   267
primitive Thm.assume_hyps.
wenzelm@55001
   268
wenzelm@55108
   269
* Inner syntax token language allows regular quoted strings "..."
wenzelm@55108
   270

wenzelm@57508
   471
* New internal SAT solver "cdclite" that produces models and proof
wenzelm@57508
   472
traces.  This solver replaces the internal SAT solvers "enumerate" and
wenzelm@57508
   473
"dpll".  Applications that explicitly used one of these two SAT
wenzelm@57508
   474
solvers should use "cdclite" instead. In addition, "cdclite" is now
wenzelm@57508
   475
the default SAT solver for the "sat" and "satx" proof methods and
wenzelm@57508
   476
corresponding tactics; the old default can be restored using "declare
wenzelm@57508
   477
[[sat_solver = zchaff_with_proofs]]".  Minor INCOMPATIBILITY.
wenzelm@57508
   478
wenzelm@57508
   479
* SMT module: A new version of the SMT module, temporarily called
wenzelm@57508
   480
"SMT2", uses SMT-LIB 2 and supports recent versions of Z3 (e.g.,
wenzelm@57508
   481
4.3). The new proof method is called "smt2". CVC3 and CVC4 are also
wenzelm@57508
   482
supported as oracles. Yices is no longer supported, because no version
wenzelm@57508
   483
of the solver can handle both SMT-LIB 2 and quantifiers.
wenzelm@57508
   484
wenzelm@57508
   485
* Activation of Z3 now works via "z3_non_commercial" system option
wenzelm@57508
   486
(without requiring restart), instead of former settings variable
wenzelm@57508
   487
"Z3_NON_COMMERCIAL".  The option can be edited in Isabelle/jEdit menu

* Sledgehammer:
wenzelm@57508
   491
  - Z3 can now produce Isar proofs.
wenzelm@57508
   492
  - MaSh overhaul:
blanchet@57532
   493
    . New SML-based learning algorithms eliminate the dependency on
wenzelm@57508
   494
      Python and increase performance and reliability.
wenzelm@57508
   495
    . MaSh and MeSh are now used by default together with the
wenzelm@57508
   496
      traditional MePo (Meng-Paulson) relevance filter. To disable
wenzelm@57508
   497
      MaSh, set the "MaSh" system option in Isabelle/jEdit Plugin
wenzelm@57508
   498
      Options / Isabelle / General to "none".
wenzelm@57508
   499
  - New option:
wenzelm@57508
   500
      smt_proofs
wenzelm@57508
   501
  - Renamed options:
wenzelm@57508

   505
INCOMPATIBILITY.
wenzelm@57508
   506
wenzelm@57508
   507
* Removed solvers remote_cvc3 and remote_z3. Use cvc3 and z3 instead.
wenzelm@57508
   508
wenzelm@57508
   509
* Nitpick:
wenzelm@57508
   510
  - Fixed soundness bug whereby mutually recursive datatypes could
wenzelm@57508
   511
    take infinite values.
wenzelm@57508
   512
  - Fixed soundness bug with low-level number functions such as
wenzelm@57508
   513
    "Abs_Integ" and "Rep_Integ".
wenzelm@57508
   514
  - Removed "std" option.
wenzelm@57508
   515
  - Renamed "show_datatypes" to "show_types" and "hide_datatypes" to
wenzelm@57508
   516
    "hide_types".
wenzelm@57508
   517
wenzelm@57508
   518
* Metis: Removed legacy proof method 'metisFT'. Use 'metis
wenzelm@57508
   519
(full_types)' instead. INCOMPATIBILITY.
wenzelm@57508
   520
wenzelm@57508
   521
* Try0: Added 'algebra' and 'meson' to the set of proof methods.
wenzelm@57508
   522
wenzelm@57508
   523
* Adjustion of INF and SUP operations:
wenzelm@57508
   524
  - Elongated constants INFI and SUPR to INFIMUM and SUPREMUM.
wenzelm@57508
   525
  - Consolidated theorem names containing INFI and SUPR: have INF and
wenzelm@57508
   526
    SUP instead uniformly.
wenzelm@57508
   527

* The signature and semantics of Document.Snapshot.cumulate_markup /
wenzelm@55622
  1065
select_markup have been clarified.  Markup is now traversed in the
wenzelm@55622
  1066
order of reports given by the prover: later markup is usually more
wenzelm@55622
  1067

guard is mandatory and checked precisely.  Subtle INCOMPATIBILITY.

wenzelm@54449
  1075
wenzelm@57504
  1076
* Subtle change of semantics of Thm.eq_thm: theory stamps are not
wenzelm@57504
  1077
compared (according to Thm.thm_ord), but assumed to be covered by the
wenzelm@57504
  1078
current background theory.  Thus equivalent data produced in different
wenzelm@57504
  1079
branches of the theory graph usually coincides (e.g. relevant for
wenzelm@57504
  1080
theory merge).  Note that the softer Thm.eq_thm_prop is often more
wenzelm@57504
  1081
appropriate than Thm.eq_thm.
wenzelm@57504
  1082
wenzelm@57504
  1083
* Proper context for basic Simplifier operations: rewrite_rule,
wenzelm@57504

rewrite_goals_rule, rewrite_goals_tac etc. INCOMPATIBILITY, need to
wenzelm@57504
  1085
pass runtime Proof.context (and ensure that the simplified entity
wenzelm@57504
  1086
actually belongs to it).
wenzelm@57504
  1087
wenzelm@57504
  1088
* Proper context discipline for read_instantiate and instantiate_tac:
wenzelm@57504
  1089
variables that are meant to become schematic need to be given as
wenzelm@57504
  1090
fixed, and are generalized by the explicit context of local variables.
wenzelm@57504
  1091
This corresponds to Isar attributes "where" and "of" with 'for'
wenzelm@57504
  1092
declaration.  INCOMPATIBILITY, also due to potential change of indices
wenzelm@57504
  1093
of schematic variables.
wenzelm@57504

wenzelm@56303

  1096
structure Runtime.  Minor INCOMPATIBILITY.
wenzelm@56303
  1097
wenzelm@56279
  1098
* Discontinued old Toplevel.debug in favour of system option
wenzelm@57452
  1099
"ML_exception_trace", which may be also declared within the context
wenzelm@57452
  1100
via "declare [[ML_exception_trace = true]]".  Minor INCOMPATIBILITY.
wenzelm@56279
  1101
wenzelm@56281
  1102

  1103
INCOMPATIBILITY.
wenzelm@56281
  1104
wenzelm@56281
  1105
* Configuration option "ML_print_depth" controls the pretty-printing
wenzelm@56281
  1106
depth of the ML compiler within the context.  The old print_depth in
wenzelm@56285
  1107
ML is still available as default_print_depth, but rarely used.  Minor
wenzelm@56285
  1108
INCOMPATIBILITY.
wenzelm@56279
  1109
wenzelm@54449
  1110
* Toplevel function "use" refers to raw ML bootstrap environment,
wenzelm@54449
  1111
without Isar context nor antiquotations.  Potential INCOMPATIBILITY.
wenzelm@54449
  1112
Note that 'ML_file' is the canonical command to load ML files into the
wenzelm@54449
  1113
formal context.
wenzelm@54449
  1114
wenzelm@56205
  1115
* Simplified programming interface to define ML antiquotations, see
wenzelm@56205
  1116
structure ML_Antiquotation.  Minor INCOMPATIBILITY.
wenzelm@56069
  1117
wenzelm@56071
  1118
* ML antiquotation @{here} refers to its source position, which is
wenzelm@56071
  1119
occasionally useful for experimentation and diagnostic purposes.
wenzelm@56071
  1120
wenzelm@56135
  1121
* ML antiquotation @{path} produces a Path.T value, similarly to
wenzelm@56135
  1122
Path.explode, but with compile-time check against the file-system and
wenzelm@56135
  1123
some PIDE markup.  Note that unlike theory source, ML does not have a
wenzelm@56135
  1124
well-defined master directory, so an absolute symbolic path
wenzelm@56135
  1125
specification is usually required, e.g. "~~/src/HOL".
wenzelm@56135
  1126
wenzelm@56399
  1127
* ML antiquotation @{print} inlines a function to print an arbitrary
wenzelm@56399
  1128

  1129
purposes.

wenzelm@57504
  1135
Isabelle component, e.g. see ProofGeneral-4.2-2 from the Isabelle
wenzelm@57504
  1136
component repository http://isabelle.in.tum.de/components/.  Note that
wenzelm@57504
  1137
the "system" manual provides general explanations about add-on
wenzelm@57504
  1138
components, especially those that are not bundled with the release.
wenzelm@57443
  1139
wenzelm@56439
  1140
* The raw Isabelle process executable has been renamed from
wenzelm@56439
  1141
"isabelle-process" to "isabelle_process", which conforms to common
wenzelm@56439
  1142
shell naming conventions, and allows to define a shell function within
wenzelm@56439
  1143
the Isabelle environment to avoid dynamic path lookup.  Rare
wenzelm@57504
  1144
incompatibility for old tools that do not use the ISABELLE_PROCESS
wenzelm@57504
  1145
settings variable.
wenzelm@56439
  1146
wenzelm@57439
  1147
* Former "isabelle tty" has been superseded by "isabelle console",
wenzelm@57439
  1148
with implicit build like "isabelle jedit", and without the mostly
wenzelm@57439
  1149
obsolete Isar TTY loop.
wenzelm@57439
  1150
wenzelm@57452
  1151
* Simplified "isabelle display" tool.  Settings variables DVI_VIEWER
wenzelm@57452
  1152
and PDF_VIEWER now refer to the actual programs, not shell
wenzelm@57452
  1153
command-lines.  Discontinued option -c: invocation may be asynchronous
wenzelm@57452
  1154
via desktop environment, without any special precautions.  Potential
wenzelm@57452
  1155
INCOMPATIBILITY with ambitious private settings.
wenzelm@57452
  1156
wenzelm@57413
  1157
* Removed obsolete "isabelle unsymbolize".  Note that the usual format
wenzelm@57413
  1158
for email communication is the Unicode rendering of Isabelle symbols,
wenzelm@57413
  1159
as produced by Isabelle/jEdit, for example.
wenzelm@57413
  1160
wenzelm@57452
  1161
* Removed obsolete tool "wwwfind". Similar functionality may be
wenzelm@57452
  1162
integrated into Isabelle/jEdit eventually.
wenzelm@57452
  1163
wenzelm@57452
  1164
* Improved 'display_drafts' concerning desktop integration and
wenzelm@57452
  1165
repeated invocation in PIDE front-end: re-use single file
wenzelm@57452
  1166
$ISABELLE_HOME_USER/tmp/drafts.pdf and corresponding views.
wenzelm@57084
  1167
wenzelm@57452
  1168
* Session ROOT specifications require explicit 'document_files' for
wenzelm@57452
  1169
robust dependencies on LaTeX sources.  Only these explicitly given
wenzelm@57452
  1170
files are copied to the document output directory, before document
wenzelm@57452
  1171
processing is started.
wenzelm@57452
  1172
wenzelm@57504
  1173
* Windows: support for regular TeX installation (e.g. MiKTeX) instead
wenzelm@57504

e.g. non-terminating 'by' steps.
wenzelm@54639
  1185

  1188
wenzelm@54648

wenzelm@51293
  1211
wenzelm@53971
  1212
* Discontinued obsolete 'uses' within theory header.  Note that
wenzelm@53971

'ML_file' in Isabelle2013.  Minor INCOMPATIBILITY.
wenzelm@53971
  1218
wenzelm@53016
  1219
* Simplified subscripts within identifiers, using plain \<^sub>
wenzelm@53016
  1220
instead of the second copy \<^isub> and \<^isup>.  Superscripts are
wenzelm@53016
  1221
only for literal tokens within notation; explicit mixfix annotations
wenzelm@53016
  1222
for consts or fixed variables may be used as fall-back for unusual

  1223
names.  Obsolete \<twosuperior> has been expanded to \<^sup>2 in
wenzelm@53016
  1224

wenzelm@53016
  1225
standardize symbols as a starting point for further manual cleanup.
wenzelm@53016
  1226
The ML reference variable "legacy_isub_isup" may be set as temporary
wenzelm@53016

  1228
syntax.

  1229
wenzelm@53021
  1230

wenzelm@52487
  1233
* Uniform management of "quick_and_dirty" as system option (see also
wenzelm@52487
  1234
"isabelle options"), configuration option within the context (see also
wenzelm@52487
  1235
Config.get in Isabelle/ML), and attribute in Isabelle/Isar.  Minor
wenzelm@52487
  1236
INCOMPATIBILITY, need to use more official Isabelle means to access
wenzelm@52487
  1237
quick_and_dirty, instead of historical poking into mutable reference.
wenzelm@52059
  1238
wenzelm@52060
  1239
* Renamed command 'print_configs' to 'print_options'.  Minor

  1240
INCOMPATIBILITY.
wenzelm@52060
  1241
wenzelm@52430
  1242
* Proper diagnostic command 'print_state'.  Old 'pr' (with its
wenzelm@52430
  1243
implicit change of some global references) is retained for now as
wenzelm@52430
  1244
control command, e.g. for ProofGeneral 3.7.x.
wenzelm@52430
  1245
wenzelm@52549
  1246
* Discontinued 'print_drafts' command with its old-fashioned PS output
wenzelm@52549
  1247
and Unix command-line print spooling.  Minor INCOMPATIBILITY: use
wenzelm@52549
  1248
'display_drafts' instead and print via the regular document viewer.
wenzelm@52549
  1249
wenzelm@53971

wenzelm@53971
  1280
wenzelm@54305
  1281
* Improved completion mechanism, which is now managed by the
wenzelm@54305
  1282
Isabelle/jEdit plugin instead of SideKick.  Refined table of Isabelle
wenzelm@54305
  1283
symbol abbreviations (see $ISABELLE_HOME/etc/symbols).
wenzelm@54305
  1284
wenzelm@54319
  1285
* Standard jEdit keyboard shortcut C+b complete-word is remapped to
wenzelm@54319
  1286
isabelle.complete for explicit completion in Isabelle sources.
wenzelm@54319
  1287
INCOMPATIBILITY wrt. jEdit defaults, may have to invent new shortcuts
wenzelm@54319
  1288
to resolve conflict.
wenzelm@54319
  1289
wenzelm@54305
  1290
* Improved support of various "minor modes" for Isabelle NEWS,
wenzelm@54305
  1291
options, session ROOT etc., with completion and SideKick tree view.
wenzelm@54305
  1292
wenzelm@53971
  1293
* Strictly monotonic document update, without premature cancellation of
wenzelm@53971
  1294
running transactions that are still needed: avoid reset/restart of
wenzelm@53971
  1295
such command executions while editing.
wenzelm@53271
  1296
wenzelm@53971
  1297
* Support for asynchronous print functions, as overlay to existing
wenzelm@53971
  1298
document content.
wenzelm@53971
  1299
wenzelm@53971
  1300
* Support for automatic tools in HOL, which try to prove or disprove
wenzelm@53971
  1301
toplevel theorem statements.
wenzelm@53971
  1302
wenzelm@53971
  1303
* Action isabelle.reset-font-size resets main text area font size
wenzelm@54365
  1304
according to Isabelle/Scala plugin option "jedit_font_reset_size" (see
wenzelm@54365
  1305
also "Plugin Options / Isabelle / General").  It can be bound to some
wenzelm@54365
  1306
keyboard shortcut by the user (e.g. C+0 and/or C+NUMPAD0).
wenzelm@53971
  1307
wenzelm@53971
  1308
* File specifications in jEdit (e.g. file browser) may refer to
wenzelm@54351
  1309
$ISABELLE_HOME and $ISABELLE_HOME_USER on all platforms.  Discontinued
wenzelm@54351
  1310
obsolete $ISABELLE_HOME_WINDOWS variable.
wenzelm@53971
  1311
wenzelm@53971
  1312
* Improved support for Linux look-and-feel "GTK+", see also "Utilities
wenzelm@53971
  1313
/ Global Options / Appearance".
wenzelm@53971
  1314
wenzelm@53971

ballarin@54049
  1321
* Commands 'interpretation' and 'sublocale' are now target-sensitive.
ballarin@54049
  1322
In particular, 'interpretation' allows for non-persistent
ballarin@54049
  1323
interpretation within "context ... begin ... end" blocks offering a
ballarin@54049
  1324
light-weight alternative to 'sublocale'.  See "isar-ref" manual for
ballarin@54049
  1325
details.
haftmann@51747
  1326
ballarin@51565
  1327
* Improved locales diagnostic command 'print_dependencies'.
ballarin@51565
  1328
wenzelm@51313
  1329
* Discontinued obsolete 'axioms' command, which has been marked as
wenzelm@51313
  1330
legacy since Isabelle2009-2.  INCOMPATIBILITY, use 'axiomatization'
wenzelm@51313
  1331
instead, while observing its uniform scope for polymorphism.
wenzelm@51313
  1332
wenzelm@51316
  1333
* Discontinued empty name bindings in 'axiomatization'.
wenzelm@51316
  1334
INCOMPATIBILITY.
wenzelm@51316
  1335
wenzelm@53971
  1336
* System option "proofs" has been discontinued.  Instead the global
wenzelm@53971
  1337
state of Proofterm.proofs is persistently compiled into logic images
wenzelm@53971
  1338
as required, notably HOL-Proofs.  Users no longer need to change
wenzelm@53971
  1339
Proofterm.proofs dynamically.  Minor INCOMPATIBILITY.
wenzelm@53971
  1340
wenzelm@53971
  1341
* Syntax translation functions (print_translation etc.) always depend
wenzelm@53971
  1342
on Proof.context.  Discontinued former "(advanced)" option -- this is
wenzelm@53971
  1343
now the default.  Minor INCOMPATIBILITY.
wenzelm@53971
  1344
wenzelm@53971
  1345
* Former global reference trace_unify_fail is now available as
wenzelm@53971
  1346
configuration option "unify_trace_failure" (global context only).
wenzelm@53971
  1347
wenzelm@52463
  1348
* SELECT_GOAL now retains the syntactic context of the overall goal
wenzelm@52463
  1349

wenzelm@52463
  1350
situations.

wenzelm@54032
  1355
* Stronger precedence of syntax for big intersection and union on
wenzelm@54032
  1356
sets, in accordance with corresponding lattice operations.
wenzelm@54032
  1357
INCOMPATIBILITY.
wenzelm@54032
  1358
wenzelm@54032
  1359
* Notation "{p:A. P}" now allows tuple patterns as well.
wenzelm@54032
  1360
wenzelm@54032
  1361
* Nested case expressions are now translated in a separate check phase
wenzelm@54032
  1362
rather than during parsing. The data for case combinators is separated
wenzelm@54032
  1363
from the datatype package. The declaration attribute
wenzelm@54032
  1364
"case_translation" can be used to register new case combinators:
wenzelm@54032
  1365
wenzelm@54032
  1366
  declare [[case_translation case_combinator constructor1 ... constructorN]]
haftmann@52637
  1367
haftmann@52435
  1368
* Code generator:
wenzelm@53160
  1369
  - 'code_printing' unifies 'code_const' / 'code_type' / 'code_class' /
wenzelm@53160
  1370
    'code_instance'.
wenzelm@53160
  1371
  - 'code_identifier' declares name hints for arbitrary identifiers in
wenzelm@53160
  1372
    generated code, subsuming 'code_modulename'.
wenzelm@53983
  1373
wenzelm@53983
  1374
See the isar-ref manual for syntax diagrams, and the HOL theories for
wenzelm@53983
  1375
examples.
haftmann@52435
  1376
wenzelm@54032
  1377
* Attibute 'code': 'code' now declares concrete and abstract code
wenzelm@54032
  1378
equations uniformly.  Use explicit 'code equation' and 'code abstract'
wenzelm@54032
  1379
to distinguish both when desired.
wenzelm@54032
  1380
wenzelm@54032
  1381
* Discontinued theories Code_Integer and Efficient_Nat by a more
wenzelm@54032
  1382
fine-grain stack of theories Code_Target_Int, Code_Binary_Nat,
wenzelm@54032
  1383
Code_Target_Nat and Code_Target_Numeral.  See the tutorial on code

  1384
generation for details.  INCOMPATIBILITY.
wenzelm@54032
  1385
wenzelm@54032
  1386
* Numeric types are mapped by default to target language numerals:
wenzelm@54032
  1387
natural (replaces former code_numeral) and integer (replaces former
wenzelm@54032
  1388
code_int).  Conversions are available as integer_of_natural /
wenzelm@54032
  1389
natural_of_integer / integer_of_nat / nat_of_integer (in HOL) and
wenzelm@54032
  1390
Code_Numeral.integer_of_natural / Code_Numeral.natural_of_integer (in
wenzelm@54032
  1391
ML).  INCOMPATIBILITY.
wenzelm@54032
  1392
wenzelm@54032
  1393
* Function package: For mutually recursive functions f and g, separate
wenzelm@54032
  1394
cases rules f.cases and g.cases are generated instead of unusable
wenzelm@54032
  1395
f_g.cases which exposed internal sum types. Potential INCOMPATIBILITY,
wenzelm@54032
  1396
in the case that the unusable rule was used nevertheless.
wenzelm@54032
  1397
wenzelm@54032
  1398
* Function package: For each function f, new rules f.elims are
wenzelm@54032
  1399
generated, which eliminate equalities of the form "f x = t".
wenzelm@54032
  1400
wenzelm@54032
  1401
* New command 'fun_cases' derives ad-hoc elimination rules for
wenzelm@54032
  1402
function equations as simplified instances of f.elims, analogous to
wenzelm@54032
  1403
inductive_cases.  See ~~/src/HOL/ex/Fundefs.thy for some examples.
blanchet@53307
  1404
kuncar@54021
  1405
* Lifting:
kuncar@54021
  1406
  - parametrized correspondence relations are now supported:
wenzelm@54378
  1407
    + parametricity theorems for the raw term can be specified in
kuncar@54021
  1408
      the command lift_definition, which allow us to generate stronger
kuncar@54021
  1409
      transfer rules
kuncar@54021
  1410
    + setup_lifting generates stronger transfer rules if parametric
kuncar@54021
  1411
      correspondence relation can be generated
kuncar@54021
  1412
    + various new properties of the relator must be specified to support
kuncar@54021
  1413
      parametricity
kuncar@54021
  1414
    + parametricity theorem for the Quotient relation can be specified
kuncar@54021
  1415
  - setup_lifting generates domain rules for the Transfer package
kuncar@54021
  1416
  - stronger reflexivity prover of respectfulness theorems for type
kuncar@54021
  1417
    copies
kuncar@54021
  1418
  - ===> and --> are now local. The symbols can be introduced
kuncar@54021
  1419
    by interpreting the locale lifting_syntax (typically in an
kuncar@54021
  1420
    anonymous context)
wenzelm@54378
  1421
  - Lifting/Transfer relevant parts of Library/Quotient_* are now in
kuncar@54021
  1422
    Main. Potential INCOMPATIBILITY
kuncar@54021
  1423
  - new commands for restoring and deleting Lifting/Transfer context:
kuncar@54021
  1424
    lifting_forget, lifting_update
wenzelm@54378
  1425
  - the command print_quotmaps was renamed to print_quot_maps.
kuncar@54021
  1426
    INCOMPATIBILITY
kuncar@54021
  1427
kuncar@54021
  1428
* Transfer:
wenzelm@54378
  1429
  - better support for domains in Transfer: replace Domainp T
kuncar@54021
  1430
    by the actual invariant in a transferred goal
kuncar@54021
  1431
  - transfer rules can have as assumptions other transfer rules
kuncar@54021
  1432
  - Experimental support for transferring from the raw level to the
kuncar@54021
  1433
    abstract level: Transfer.transferred attribute
kuncar@54021
  1434
  - Attribute version of the transfer method: untransferred attribute
kuncar@54021
  1435
haftmann@52286
  1436
* Reification and reflection:
wenzelm@53160
  1437
  - Reification is now directly available in HOL-Main in structure
wenzelm@53160
  1438
    "Reification".
wenzelm@53160
  1439
  - Reflection now handles multiple lists with variables also.
wenzelm@53160
  1440
  - The whole reflection stack has been decomposed into conversions.
haftmann@52286
  1441
INCOMPATIBILITY.
haftmann@52286
  1442
haftmann@51489
  1443
* Revised devices for recursive definitions over finite sets:
haftmann@51489
  1444
  - Only one fundamental fold combinator on finite set remains:
haftmann@51489
  1445
    Finite_Set.fold :: ('a => 'b => 'b) => 'b => 'a set => 'b
haftmann@51489
  1446
    This is now identity on infinite sets.
wenzelm@52745
  1447
  - Locales ("mini packages") for fundamental definitions with
haftmann@51489
  1448
    Finite_Set.fold: folding, folding_idem.
haftmann@51489
  1449
  - Locales comm_monoid_set, semilattice_order_set and
haftmann@51489
  1450
    semilattice_neutr_order_set for big operators on sets.
haftmann@51489
  1451
    See theory Big_Operators for canonical examples.
haftmann@51489
  1452
    Note that foundational constants comm_monoid_set.F and
haftmann@51489
  1453
    semilattice_set.F correspond to former combinators fold_image
haftmann@51489
  1454
    and fold1 respectively.  These are now gone.  You may use
haftmann@51490
  1455
    those foundational constants as substitutes, but it is
wenzelm@53983
  1456
    preferable to interpret the above locales accordingly.
haftmann@51489
  1457
  - Dropped class ab_semigroup_idem_mult (special case of lattice,
haftmann@51489
  1458
    no longer needed in connection with Finite_Set.fold etc.)
haftmann@51489
  1459
  - Fact renames:
haftmann@51489
  1460
      card.union_inter ~> card_Un_Int [symmetric]
haftmann@51489
  1461
      card.union_disjoint ~> card_Un_disjoint
haftmann@51489
  1462
INCOMPATIBILITY.
haftmann@51489
  1463
haftmann@51487
  1464
* Locale hierarchy for abstract orderings and (semi)lattices.
haftmann@51487
  1465
wenzelm@53526
  1466
* Complete_Partial_Order.admissible is defined outside the type class
wenzelm@53526
  1467
ccpo, but with mandatory prefix ccpo. Admissibility theorems lose the
wenzelm@53526
  1468
class predicate assumption or sort constraint when possible.
Andreas@53362
  1469
INCOMPATIBILITY.
Andreas@53362
  1470
wenzelm@53160
  1471
* Introduce type class "conditionally_complete_lattice": Like a
wenzelm@53160
  1472
complete lattice but does not assume the existence of the top and
wenzelm@53160
  1473
bottom elements.  Allows to generalize some lemmas about reals and
wenzelm@53160
  1474
extended reals.  Removed SupInf and replaced it by the instantiation
wenzelm@53160
  1475
of conditionally_complete_lattice for real. Renamed lemmas about
wenzelm@53160
  1476
conditionally-complete lattice from Sup_... to cSup_... and from
wenzelm@53160
  1477
Inf_...  to cInf_... to avoid hidding of similar complete lattice
wenzelm@53160
  1478
lemmas.
wenzelm@53160
  1479
wenzelm@53160
  1480
* Introduce type class linear_continuum as combination of
wenzelm@53160
  1481
conditionally-complete lattices and inner dense linorders which have
wenzelm@53160
  1482
more than one element.  INCOMPATIBILITY.
wenzelm@53160
  1483
wenzelm@53983
  1484
* Introduced type classes order_top and order_bot. The old classes top
wenzelm@53983
  1485
and bot only contain the syntax without assumptions.  INCOMPATIBILITY:
wenzelm@53983
  1486
Rename bot -> order_bot, top -> order_top
lammich@53683
  1487
wenzelm@53160
  1488
* Introduce type classes "no_top" and "no_bot" for orderings without
wenzelm@53160
  1489
top and bottom elements.
hoelzl@51732
  1490
hoelzl@51732
  1491
* Split dense_linorder into inner_dense_order and no_top, no_bot.
hoelzl@51732
  1492
hoelzl@51732
  1493
* Complex_Main: Unify and move various concepts from
wenzelm@53160
  1494
HOL-Multivariate_Analysis to HOL-Complex_Main.
hoelzl@51732
  1495
wenzelm@53983
  1496
 - Introduce type class (lin)order_topology and
wenzelm@53983
  1497
   linear_continuum_topology.  Allows to generalize theorems about
wenzelm@53983
  1498
   limits and order.  Instances are reals and extended reals.
hoelzl@51732
  1499
hoelzl@51732
  1500
 - continuous and continuos_on from Multivariate_Analysis:
wenzelm@53983
  1501
   "continuous" is the continuity of a function at a filter.  "isCont"
wenzelm@53983
  1502
   is now an abbrevitation: "isCont x f == continuous (at _) f".
wenzelm@53983
  1503
wenzelm@53983
  1504
   Generalized continuity lemmas from isCont to continuous on an
wenzelm@53983
  1505
   arbitrary filter.
wenzelm@53983
  1506
wenzelm@53983
  1507
 - compact from Multivariate_Analysis. Use Bolzano's lemma to prove
wenzelm@53983
  1508
   compactness of closed intervals on reals. Continuous functions
wenzelm@53983
  1509
   attain infimum and supremum on compact sets. The inverse of a
wenzelm@53983
  1510
   continuous function is continuous, when the function is continuous
wenzelm@53983
  1511
   on a compact set.
hoelzl@51732
  1512
hoelzl@51732
  1513
 - connected from Multivariate_Analysis. Use it to prove the
hoelzl@51775
  1514
   intermediate value theorem. Show connectedness of intervals on
hoelzl@51775
  1515
   linear_continuum_topology).
hoelzl@51732
  1516
hoelzl@51732
  1517
 - first_countable_topology from Multivariate_Analysis. Is used to
wenzelm@53983
  1518
   show equivalence of properties on the neighbourhood filter of x and
wenzelm@53983
  1519
   on all sequences converging to x.
wenzelm@53983
  1520
wenzelm@53983
  1521
 - FDERIV: Definition of has_derivative moved to Deriv.thy. Moved
wenzelm@53983
  1522
   theorems from Library/FDERIV.thy to Deriv.thy and base the
wenzelm@53983
  1523
   definition of DERIV on FDERIV. Add variants of DERIV and FDERIV
wenzelm@53983
  1524
   which are restricted to sets, i.e. to represent derivatives from
wenzelm@53983
  1525
   left or right.
hoelzl@51732
  1526
hoelzl@51732
  1527
 - Removed the within-filter. It is replaced by the principal filter:
hoelzl@51732
  1528
hoelzl@51732
  1529
     F within X = inf F (principal X)
hoelzl@51732
  1530
hoelzl@51732
  1531
 - Introduce "at x within U" as a single constant, "at x" is now an
hoelzl@51732
  1532
   abbreviation for "at x within UNIV"
hoelzl@51732
  1533
wenzelm@53983
  1534
 - Introduce named theorem collections tendsto_intros,
wenzelm@53983
  1535
   continuous_intros, continuous_on_intros and FDERIV_intros. Theorems
wenzelm@53983
  1536
   in tendsto_intros (or FDERIV_intros) are also available as
wenzelm@53983
  1537
   tendsto_eq_intros (or FDERIV_eq_intros) where the right-hand side
wenzelm@53983
  1538
   is replaced by a congruence rule. This allows to apply them as
wenzelm@53983
  1539
   intro rules and then proving equivalence by the simplifier.
hoelzl@51732
  1540
hoelzl@51732
  1541
 - Restructured theories in HOL-Complex_Main:
hoelzl@51732
  1542
hoelzl@51732
  1543
   + Moved RealDef and RComplete into Real
hoelzl@51732
  1544
hoelzl@51732
  1545
   + Introduced Topological_Spaces and moved theorems about
hoelzl@51732
  1546
     topological spaces, filters, limits and continuity to it
hoelzl@51732
  1547
hoelzl@51732
  1548
   + Renamed RealVector to Real_Vector_Spaces
hoelzl@51732

* Spec_Check is a Quickcheck tool for Isabelle/ML.  The ML function
wenzelm@53971
  1638
"check_property" allows to check specifications of the form "ALL x y

Minor INCOMPATIBILITY.
wenzelm@51703
  1659
wenzelm@51717

* Simplifier tactics and tools use proper Proof.context instead of
wenzelm@51717
  1661
historic type simpset.  Old-style declarations like addsimps,
wenzelm@51717
  1662
addsimprocs etc. operate directly on Proof.context.  Raw type simpset
wenzelm@51717
  1663
retains its use as snapshot of the main Simplifier context, using
wenzelm@51717
  1664
simpset_of and put_simpset on Proof.context.  INCOMPATIBILITY -- port
wenzelm@51717
  1665
old tools by making them depend on (ctxt : Proof.context) instead of
wenzelm@51717
  1666
(ss : simpset), then turn (simpset_of ctxt) into ctxt.
wenzelm@51717
  1667
wenzelm@53971
  1668
* Modifiers for classical wrappers (e.g. addWrapper, delWrapper)
wenzelm@53971
  1669
operate on Proof.context instead of claset, for uniformity with addIs,
wenzelm@53971
  1670
addEs, addDs etc. Note that claset_of and put_claset allow to manage
wenzelm@53971
  1671
clasets separately from the context.
wenzelm@53971
  1672
wenzelm@51717
  1673
* Discontinued obsolete ML antiquotations @{claset} and @{simpset}.

  1704
wenzelm@53971
  1705
* Sessions may be organized via 'chapter' specifications in the ROOT

wenzelm@50126
  1719
* Theorem status about oracles and unfinished/failed future proofs is
wenzelm@50126
  1720
no longer printed by default, since it is incompatible with
wenzelm@50126
  1721
incremental / parallel checking of the persistent document model.  ML
wenzelm@50126
  1722
function Thm.peek_status may be used to inspect a snapshot of the
wenzelm@50126
  1723
ongoing evaluation process.  Note that in batch mode --- notably
wenzelm@50126
  1724
isabelle build --- the system ensures that future proofs of all
wenzelm@50126
  1725
accessible theorems in the theory context are finished (as before).
wenzelm@50126
  1726
wenzelm@49699
  1727
* Configuration option show_markup controls direct inlining of markup
wenzelm@49699
  1728
into the printed representation of formal entities --- notably type
wenzelm@49699
  1729
and sort constraints.  This enables Prover IDE users to retrieve that
wenzelm@49699
  1730
information via tooltips in the output window, for example.
wenzelm@49699
  1731
wenzelm@48890
  1732
* Command 'ML_file' evaluates ML text from a file directly within the
wenzelm@48890
  1733
theory, without any predeclaration via 'uses' in the theory header.
wenzelm@48890
  1734
wenzelm@49243
  1735
* Old command 'use' command and corresponding keyword 'uses' in the
wenzelm@49243
  1736
theory header are legacy features and will be discontinued soon.
wenzelm@49243
  1737
Tools that load their additional source files may imitate the
wenzelm@49243
  1738
'ML_file' implementation, such that the system can take care of
wenzelm@49243
  1739
dependencies properly.
wenzelm@49243
  1740
wenzelm@47967
  1741
* Discontinued obsolete method fastsimp / tactic fast_simp_tac, which
wenzelm@47967
  1742
is called fastforce / fast_force_tac already since Isabelle2011-1.
wenzelm@47967
  1743
wenzelm@50110
  1744
* Updated and extended "isar-ref" and "implementation" manual, reduced
wenzelm@50110
  1745
remaining material in old "ref" manual.
wenzelm@48120
  1746
wenzelm@51050
  1747
* Improved support for auxiliary contexts that indicate block structure
wenzelm@51050
  1748
for specifications.  Nesting of "context fixes ... context assumes ..."
wenzelm@49841
  1749
and "class ... context ...".
wenzelm@49841
  1750
wenzelm@50772
  1751
* Attribute "consumes" allows a negative value as well, which is
wenzelm@50778
  1752
interpreted relatively to the total number of premises of the rule in
wenzelm@50772
  1753
the target context.  This form of declaration is stable when exported
wenzelm@50772
  1754
from a nested 'context' with additional assumptions.  It is the
wenzelm@50772
  1755
preferred form for definitional packages, notably cases/rules produced
wenzelm@50772
  1756
in HOL/inductive and HOL/function.
wenzelm@50772
  1757
wenzelm@49869
  1758
* More informative error messages for Isar proof commands involving
wenzelm@49869
  1759
lazy enumerations (method applications etc.).
wenzelm@49869
  1760
wenzelm@50213
  1761
* Refined 'help' command to retrieve outer syntax commands according
wenzelm@50213

*** Prover IDE -- Isabelle/Scala/jEdit ***
wenzelm@49968
  1766
wenzelm@49968
  1767
* Parallel terminal proofs ('by') are enabled by default, likewise
wenzelm@49968
  1768
proofs that are built into packages like 'datatype', 'function'.  This
wenzelm@49968
  1769
allows to "run ahead" checking the theory specifications on the
wenzelm@49968
  1770
surface, while the prover is still crunching on internal
wenzelm@49968
  1771
justifications.  Unfinished / cancelled proofs are restarted as
wenzelm@49968
  1772
required to complete full proof checking eventually.
wenzelm@49968
  1773
wenzelm@49968
  1774
* Improved output panel with tooltips, hyperlinks etc. based on the
wenzelm@49968
  1775
same Rich_Text_Area as regular Isabelle/jEdit buffers.  Activation of
wenzelm@49968
  1776
tooltips leads to some window that supports the same recursively,
wenzelm@49968
  1777
which can lead to stacks of tooltips as the semantic document content
wenzelm@49968
  1778
is explored.  ESCAPE closes the whole stack, individual windows may be
wenzelm@49968
  1779
closed separately, or detached to become independent jEdit dockables.
wenzelm@49968
  1780
wenzelm@50717
  1781
* Improved support for commands that produce graph output: the text
wenzelm@50717
  1782
message contains a clickable area to open a new instance of the graph
wenzelm@50717
  1783
browser on demand.
wenzelm@50717
  1784
wenzelm@49968
  1785
* More robust incremental parsing of outer syntax (partial comments,
wenzelm@49968
  1786
malformed symbols).  Changing the balance of open/close quotes and
wenzelm@49968
  1787
comment delimiters works more conveniently with unfinished situations
wenzelm@49968
  1788
that frequently occur in user interaction.
wenzelm@49968
  1789
wenzelm@49968
  1790
* More efficient painting and improved reactivity when editing large
wenzelm@49968
  1791
files.  More scalable management of formal document content.
wenzelm@49968
  1792
wenzelm@50505
  1793
* Smarter handling of tracing messages: prover process pauses after
wenzelm@50505
  1794
certain number of messages per command transaction, with some user
wenzelm@50505
  1795
dialog to stop or continue.  This avoids swamping the front-end with
wenzelm@50119
  1796
potentially infinite message streams.
wenzelm@49968
  1797
wenzelm@49968
  1798
* More plugin options and preferences, based on Isabelle/Scala.  The
wenzelm@49968
  1799
jEdit plugin option panel provides access to some Isabelle/Scala
wenzelm@49968
  1800
options, including tuning parameters for editor reactivity and color
wenzelm@49968
  1801
schemes.
wenzelm@49968
  1802
wenzelm@50184
  1803
* Dockable window "Symbols" provides some editing support for Isabelle
wenzelm@50184
  1804
symbols.
wenzelm@50184
  1805
wenzelm@51082
  1806
* Dockable window "Monitor" shows ML runtime statistics.  Note that
wenzelm@51082
  1807
continuous display of the chart slows down the system.
wenzelm@50701
  1808
wenzelm@50183
  1809
* Improved editing support for control styles: subscript, superscript,
wenzelm@50183
  1810
bold, reset of style -- operating on single symbols or text
wenzelm@50198
  1811
selections.  Cf. keyboard shortcuts C+e DOWN/UP/RIGHT/LEFT.
wenzelm@50198
  1812
wenzelm@50198
  1813
* Actions isabelle.increase-font-size and isabelle.decrease-font-size
wenzelm@50198
  1814
adjust the main text area font size, and its derivatives for output,
wenzelm@50836
  1815
tooltips etc.  Cf. keyboard shortcuts C-PLUS and C-MINUS, which often
wenzelm@50836
  1816
need to be adapted to local keyboard layouts.
wenzelm@50183
  1817
wenzelm@50730
  1818
* More reactive completion popup by default: use \t (TAB) instead of
wenzelm@50730
  1819
\n (NEWLINE) to minimize intrusion into regular flow of editing.  See
wenzelm@50730
  1820
also "Plugin Options / SideKick / General / Code Completion Options".
wenzelm@50730
  1821
wenzelm@50406
  1822
* Implicit check and build dialog of the specified logic session
wenzelm@50406
  1823
image.  For example, HOL, HOLCF, HOL-Nominal can be produced on
wenzelm@50406
  1824

structure instead.  Note that Isabelle/ML provides a variety of
wenzelm@48205
  1844
operators like COMP, INCR_COMP, COMP_INCR, which need to be applied

* Generalized the definition of limits:
wenzelm@50646
  1930
wenzelm@50646
  1931
  - Introduced the predicate filterlim (LIM x F. f x :> G) which
wenzelm@50646
  1932
    expresses that when the input values x converge to F then the
wenzelm@50646
  1933
    output f x converges to G.
wenzelm@50646
  1934
wenzelm@50646
  1935
  - Added filters for convergence to positive (at_top) and negative
wenzelm@50646

    infinity (at_bot).
wenzelm@50646
  1937
wenzelm@50646
  1938
  - Moved infinity in the norm (at_infinity) from

  1940
wenzelm@50646
  1941
  - Removed real_tendsto_inf, it is superseded by "LIM x F. f x :>

  1963
wenzelm@50646
  1964
  - Replaced constant "postfix" by "suffixeq" with swapped argument
wenzelm@50646
  1965
    order (i.e., "postfix xs ys" is now "suffixeq ys xs") and dropped
wenzelm@50646
  1966
    old infix syntax "xs >>= ys"; use "suffixeq ys xs" instead.
wenzelm@50646
  1967
    Renamed lemmas accordingly.
wenzelm@50646
  1968
wenzelm@50646
  1969

wenzelm@50646
  1974
    class instances for the prefix order (merely corresponding locale
wenzelm@50646

wenzelm@50646
  2108
* Dropped legacy antiquotations "term_style" and "thm_style", since
wenzelm@50646
  2109
styles may be given as arguments to "term" and "thm" already.
wenzelm@50646
  2110
Discontinued legacy styles "prem1" .. "prem19".
wenzelm@50646
  2111
wenzelm@50646
  2112
* Default LaTeX rendering for \<euro> is now based on eurosym package,
wenzelm@50646
  2113
instead of slightly exotic babel/greek.
wenzelm@48206
  2114
wenzelm@48616
  2115
* Document variant NAME may use different LaTeX entry point
wenzelm@48616
  2116
document/root_NAME.tex if that file exists, instead of the common
wenzelm@48616
  2117
document/root.tex.
wenzelm@48616
  2118
wenzelm@48657
  2119
* Simplified custom document/build script, instead of old-style

wenzelm@50646
  2125
* The default limit for maximum number of worker threads is now 8,
wenzelm@50646
  2126
instead of 4, in correspondence to capabilities of contemporary
wenzelm@50646
  2127
hardware and Poly/ML runtime system.
wenzelm@50646
  2128
wenzelm@49869
  2129
* Type Seq.results and related operations support embedded error
wenzelm@49869
  2130
messages within lazy enumerations, and thus allow to provide
wenzelm@49869
  2131
informative errors in the absence of any usable results.
wenzelm@49869
  2132
wenzelm@48992
  2133
* Renamed Position.str_of to Position.here to emphasize that this is a
wenzelm@48992
  2134
formal device to inline positions into message text, but not
wenzelm@48992
  2135
necessarily printing visible text.

*** System ***
wenzelm@48206
  2139
wenzelm@48585
  2140
* Advanced support for Isabelle sessions and build management, see
wenzelm@48585
  2141
"system" manual for the chapter of that name, especially the "isabelle
wenzelm@51056
  2142
build" tool and its examples.  The "isabelle mkroot" tool prepares
wenzelm@51056
  2143
session root directories for use with "isabelle build", similar to
wenzelm@51056
  2144
former "isabelle mkdir" for "isabelle usedir".  Note that this affects
wenzelm@51056
  2145
document preparation as well.  INCOMPATIBILITY, isabelle usedir /
wenzelm@48736
  2146
mkdir / make are rendered obsolete.
wenzelm@48736
  2147
wenzelm@51056
  2148
* Discontinued obsolete Isabelle/build script, it is superseded by the
wenzelm@51056
  2149
regular isabelle build tool.  For example:
wenzelm@51056
  2150
wenzelm@51056
  2151
  isabelle build -s -b HOL
wenzelm@51056
  2152
wenzelm@48736
  2153
* Discontinued obsolete "isabelle makeall".
wenzelm@48585
  2154
wenzelm@48722
  2155
* Discontinued obsolete IsaMakefile and ROOT.ML files from the
wenzelm@48722
  2156
Isabelle distribution, except for rudimentary src/HOL/IsaMakefile that
wenzelm@48722
  2157
provides some traditional targets that invoke "isabelle build".  Note
wenzelm@48722
  2158
that this is inefficient!  Applications of Isabelle/HOL involving
wenzelm@48722
  2159
"isabelle make" should be upgraded to use "isabelle build" directly.
wenzelm@48722
  2160
wenzelm@48693
  2161
* The "isabelle options" tool prints Isabelle system options, as
wenzelm@48693
  2162
required for "isabelle build", for example.
wenzelm@48693
  2163
wenzelm@50646
  2164
* The "isabelle logo" tool produces EPS and PDF format simultaneously.
wenzelm@50646
  2165
Minor INCOMPATIBILITY in command-line options.
wenzelm@50646
  2166
wenzelm@50646
  2167
* The "isabelle install" tool has now a simpler command-line.  Minor
wenzelm@50646
  2168
INCOMPATIBILITY.
wenzelm@50646
  2169
wenzelm@48844
  2170
* The "isabelle components" tool helps to resolve add-on components
wenzelm@48844
  2171
that are not bundled, or referenced from a bare-bones repository
wenzelm@48844
  2172
version of Isabelle.
wenzelm@48844
  2173
wenzelm@50646
  2174
* Settings variable ISABELLE_PLATFORM_FAMILY refers to the general
wenzelm@50646
  2175
platform family: "linux", "macos", "windows".
wenzelm@50646
  2176
wenzelm@50646
  2177
* The ML system is configured as regular component, and no longer
wenzelm@50646
  2178
picked up from some surrounding directory.  Potential INCOMPATIBILITY
wenzelm@50646
  2179
for home-made settings.
wenzelm@50132
  2180
wenzelm@50701
  2181
* Improved ML runtime statistics (heap, threads, future tasks etc.).
wenzelm@50701
  2182
wenzelm@48206
  2183
* Discontinued support for Poly/ML 5.2.1, which was the last version
wenzelm@48206
  2184
without exception positions and advanced ML compiler/toplevel
wenzelm@48206
  2185
configuration.
wenzelm@48206
  2186
wenzelm@48574
  2187
* Discontinued special treatment of Proof General -- no longer guess
wenzelm@48574
  2188
PROOFGENERAL_HOME based on accidental file-system layout.  Minor
wenzelm@48574
  2189
INCOMPATIBILITY: provide PROOFGENERAL_HOME and PROOFGENERAL_OPTIONS
wenzelm@48574
  2190
settings manually, or use a Proof General version that has been
wenzelm@48574
  2191
bundled as Isabelle component.

wenzelm@45593
  2198
*** General ***
wenzelm@45593
  2199
wenzelm@45614
  2200
* Prover IDE (PIDE) improvements:
wenzelm@45614
  2201
wenzelm@47585
  2202
  - more robust Sledgehammer integration (as before the sledgehammer
wenzelm@47806
  2203
    command-line needs to be typed into the source buffer)
wenzelm@45614
  2204
  - markup for bound variables
wenzelm@47806
  2205
  - markup for types of term variables (displayed as tooltips)
wenzelm@46956
  2206
  - support for user-defined Isar commands within the running session
wenzelm@47158
  2207
  - improved support for Unicode outside original 16bit range
wenzelm@47158
  2208
    e.g. glyph for \<A> (thanks to jEdit 4.5.1)
wenzelm@45614
  2209
wenzelm@47806
  2210
* Forward declaration of outer syntax keywords within the theory
wenzelm@47806
  2211
header -- minor INCOMPATIBILITY for user-defined commands.  Allow new
wenzelm@47806
  2212
commands to be used in the same theory where defined.
wenzelm@46485
  2213
wenzelm@47482
  2214
* Auxiliary contexts indicate block structure for specifications with
wenzelm@47482
  2215
additional parameters and assumptions.  Such unnamed contexts may be
wenzelm@47482
  2216
nested within other targets, like 'theory', 'locale', 'class',
wenzelm@47482
  2217
'instantiation' etc.  Results from the local context are generalized
wenzelm@47482
  2218
accordingly and applied to the enclosing target context.  Example:
wenzelm@47482
  2219
wenzelm@47482
  2220
  context
wenzelm@47482
  2221
    fixes x y z :: 'a
wenzelm@47482
  2222
    assumes xy: "x = y" and yz: "y = z"
wenzelm@47482
  2223
  begin
wenzelm@47482
  2224
wenzelm@47482
  2225
  lemma my_trans: "x = z" using xy yz by simp
wenzelm@47482
  2226
wenzelm@47482
  2227
  end
wenzelm@47482
  2228
wenzelm@47482
  2229
  thm my_trans
wenzelm@47482
  2230
wenzelm@47482
  2231
The most basic application is to factor-out context elements of
wenzelm@47482
  2232
several fixes/assumes/shows theorem statements, e.g. see
wenzelm@47482
  2233
~~/src/HOL/Isar_Examples/Group_Context.thy
wenzelm@47482
  2234
wenzelm@47482
  2235
Any other local theory specification element works within the "context
wenzelm@47482
  2236
... begin ... end" block as well.
wenzelm@47482
  2237
wenzelm@47484
  2238
* Bundled declarations associate attributed fact expressions with a
wenzelm@47484
  2239
given name in the context.  These may be later included in other
wenzelm@47484
  2240
contexts.  This allows to manage context extensions casually, without
wenzelm@47855
  2241
the logical dependencies of locales and locale interpretation.  See
wenzelm@47855
  2242
commands 'bundle', 'include', 'including' etc. in the isar-ref manual.
wenzelm@47484
  2243
wenzelm@47829
  2244
* Commands 'lemmas' and 'theorems' allow local variables using 'for'
wenzelm@47829
  2245
declaration, and results are standardized before being stored.  Thus
wenzelm@47829
  2246
old-style "standard" after instantiation or composition of facts
wenzelm@47829
  2247
becomes obsolete.  Minor INCOMPATIBILITY, due to potential change of
wenzelm@47829
  2248
indices of schematic variables.
wenzelm@47829
  2249
wenzelm@47829
  2250
* Rule attributes in local theory declarations (e.g. locale or class)
wenzelm@47829
  2251
are now statically evaluated: the resulting theorem is stored instead
wenzelm@47829
  2252
of the original expression.  INCOMPATIBILITY in rare situations, where
wenzelm@47829
  2253
the historic accident of dynamic re-evaluation in interpretations
wenzelm@47829
  2254
etc. was exploited.
wenzelm@47829
  2255
wenzelm@47829
  2256
* New tutorial "Programming and Proving in Isabelle/HOL"
wenzelm@47829
  2257
("prog-prove").  It completely supersedes "A Tutorial Introduction to
wenzelm@47829
  2258
Structured Isar Proofs" ("isar-overview"), which has been removed.  It
wenzelm@47829
  2259
also supersedes "Isabelle/HOL, A Proof Assistant for Higher-Order
wenzelm@47829
  2260
Logic" as the recommended beginners tutorial, but does not cover all
wenzelm@47829
  2261
of the material of that old tutorial.
wenzelm@47829
  2262
wenzelm@47829
  2263
* Updated and extended reference manuals: "isar-ref",
wenzelm@47829
  2264
"implementation", "system"; reduced remaining material in old "ref"
wenzelm@47829
  2265
manual.

wenzelm@47829
  2268
*** Pure ***
wenzelm@47829
  2269
wenzelm@46976
  2270
* Command 'definition' no longer exports the foundational "raw_def"
wenzelm@46976
  2271
into the user context.  Minor INCOMPATIBILITY, may use the regular
wenzelm@46976
  2272
"def" result with attribute "abs_def" to imitate the old version.
wenzelm@46976
  2273
wenzelm@47855
  2274
* Attribute "abs_def" turns an equation of the form "f x y == t" into
wenzelm@47855
  2275
"f == %x y. t", which ensures that "simp" or "unfold" steps always
wenzelm@47855
  2276
expand it.  This also works for object-logic equality.  (Formerly
wenzelm@47855
  2277
undocumented feature.)
wenzelm@47855
  2278
wenzelm@47856
  2279
* Sort constraints are now propagated in simultaneous statements, just
wenzelm@47856
  2280
like type constraints.  INCOMPATIBILITY in rare situations, where
wenzelm@47856
  2281
distinct sorts used to be assigned accidentally.  For example:
wenzelm@47856
  2282
wenzelm@47856
  2283
  lemma "P (x::'a::foo)" and "Q (y::'a::bar)"  -- "now illegal"
wenzelm@47856
  2284
wenzelm@47856
  2285
  lemma "P (x::'a)" and "Q (y::'a::bar)"
wenzelm@47856
  2286
    -- "now uniform 'a::bar instead of default sort for first occurrence (!)"
wenzelm@47856
  2287
wenzelm@47856
  2288
* Rule composition via attribute "OF" (or ML functions OF/MRS) is more
wenzelm@47856
  2289
tolerant against multiple unifiers, as long as the final result is
wenzelm@47856
  2290
unique.  (As before, rules are composed in canonical right-to-left
wenzelm@47856
  2291
order to accommodate newly introduced premises.)
wenzelm@47856
  2292
wenzelm@47806
  2293
* Renamed some inner syntax categories:
wenzelm@47806
  2294
wenzelm@47806
  2295
    num ~> num_token
wenzelm@47806
  2296
    xnum ~> xnum_token
wenzelm@47806
  2297
    xstr ~> str_token
wenzelm@47806
  2298
wenzelm@47806
  2299
Minor INCOMPATIBILITY.  Note that in practice "num_const" or
wenzelm@47806
  2300
"num_position" etc. are mainly used instead (which also include
wenzelm@47806
  2301
position information via constraints).
wenzelm@47806
  2302
wenzelm@47829
  2303
* Simplified configuration options for syntax ambiguity: see
wenzelm@47829
  2304
"syntax_ambiguity_warning" and "syntax_ambiguity_limit" in isar-ref
wenzelm@47829
  2305
manual.  Minor INCOMPATIBILITY.
wenzelm@47829
  2306
wenzelm@47856
  2307
* Discontinued configuration option "syntax_positions": atomic terms
wenzelm@47856
  2308
in parse trees are always annotated by position constraints.
wenzelm@45134
  2309
wenzelm@47464
  2310
* Old code generator for SML and its commands 'code_module',
wenzelm@45383
  2311
'code_library', 'consts_code', 'types_code' have been discontinued.
haftmann@46028
  2312
Use commands of the generic code generator instead.  INCOMPATIBILITY.
wenzelm@45383
  2313
wenzelm@47464
  2314
* Redundant attribute "code_inline" has been discontinued. Use
wenzelm@47464
  2315
"code_unfold" instead.  INCOMPATIBILITY.
wenzelm@47464
  2316
wenzelm@47464
  2317
* Dropped attribute "code_unfold_post" in favor of the its dual
wenzelm@47464
  2318
"code_abbrev", which yields a common pattern in definitions like
haftmann@46028
  2319
haftmann@46028
  2320
  definition [code_abbrev]: "f = t"
haftmann@46028
  2321
haftmann@46028
  2322
INCOMPATIBILITY.
wenzelm@45383
  2323
wenzelm@47856
  2324
* Obsolete 'types' command has been discontinued.  Use 'type_synonym'
wenzelm@47856
  2325
instead.  INCOMPATIBILITY.
wenzelm@47856
  2326
wenzelm@47856
  2327
* Discontinued old "prems" fact, which used to refer to the accidental
wenzelm@47856
  2328
collection of foundational premises in the context (already marked as
wenzelm@47856
  2329
legacy since Isabelle2011).

* Type 'a set is now a proper type constructor (just as before
wenzelm@47464
  2335
Isabelle2008).  Definitions mem_def and Collect_def have disappeared.
wenzelm@47464
  2336
Non-trivial INCOMPATIBILITY.  For developments keeping predicates and
wenzelm@47855
  2337
sets separate, it is often sufficient to rephrase some set S that has
wenzelm@47855
  2338
been accidentally used as predicates by "%x. x : S", and some
wenzelm@47855
  2339
predicate P that has been accidentally used as set by "{x. P x}".
wenzelm@47855
  2340
Corresponding proofs in a first step should be pruned from any
wenzelm@47855
  2341
tinkering with former theorems mem_def and Collect_def as far as
wenzelm@47855
  2342
possible.
wenzelm@47855
  2343
wenzelm@47855
  2344
For developments which deliberately mix predicates and sets, a
wenzelm@47464
  2345
planning step is necessary to determine what should become a predicate
wenzelm@47464
  2346
and what a set.  It can be helpful to carry out that step in
wenzelm@47464
  2347
Isabelle2011-1 before jumping right into the current release.
wenzelm@47464
  2348
wenzelm@47855
  2349
* Code generation by default implements sets as container type rather
wenzelm@47855
  2350
than predicates.  INCOMPATIBILITY.
wenzelm@47855
  2351
wenzelm@47855

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

wenzelm@47464
  2354
* The representation of numerals has changed.  Datatype "num"
wenzelm@47464
  2355
represents strictly positive binary numerals, along with functions
wenzelm@47464
  2356
"numeral :: num => 'a" and "neg_numeral :: num => 'a" to represent
wenzelm@47855
  2357
positive and negated numeric literals, respectively.  See also
wenzelm@47855
  2358
definitions in ~~/src/HOL/Num.thy.  Potential INCOMPATIBILITY, some
wenzelm@47855
  2359
user theories may require adaptations as follows:
huffman@47108
  2360
huffman@47108
  2361
  - Theorems with number_ring or number_semiring constraints: These
huffman@47108
  2362
    classes are gone; use comm_ring_1 or comm_semiring_1 instead.
huffman@47108
  2363
huffman@47108
  2364
  - Theories defining numeric types: Remove number, number_semiring,
huffman@47108
  2365
    and number_ring instances. Defer all theorems about numerals until
huffman@47108
  2366
    after classes one and semigroup_add have been instantiated.
huffman@47108
  2367
huffman@47108
  2368
  - Numeral-only simp rules: Replace each rule having a "number_of v"
huffman@47108
  2369
    pattern with two copies, one for numeral and one for neg_numeral.
huffman@47108
  2370
huffman@47108
  2371
  - Theorems about subclasses of semiring_1 or ring_1: These classes
huffman@47108
  2372
    automatically support numerals now, so more simp rules and
huffman@47108
  2373
    simprocs may now apply within the proof.
huffman@47108
  2374
huffman@47108

* Transfer: New package intended to generalize the existing
wenzelm@47855
  2379
"descending" method and related theorem attributes from the Quotient
wenzelm@47855
  2380
package.  (Not all functionality is implemented yet, but future
wenzelm@47855
  2381
development will focus on Transfer as an eventual replacement for the
wenzelm@47855
  2382
corresponding parts of the Quotient package.)
wenzelm@47809
  2383
wenzelm@47809
  2384
  - transfer_rule attribute: Maintains a collection of transfer rules,
wenzelm@47809
  2385
    which relate constants at two different types. Transfer rules may
wenzelm@47809
  2386
    relate different type instances of the same polymorphic constant,
wenzelm@47809
  2387
    or they may relate an operation on a raw type to a corresponding
wenzelm@47809
  2388
    operation on an abstract type (quotient or subtype). For example:
wenzelm@47809
  2389
wenzelm@47809
  2390
    ((A ===> B) ===> list_all2 A ===> list_all2 B) map map
wenzelm@47809
  2391
    (cr_int ===> cr_int ===> cr_int) (%(x,y) (u,v). (x+u, y+v)) plus_int
wenzelm@47809
  2392
wenzelm@47809
  2393
  - transfer method: Replaces a subgoal on abstract types with an
wenzelm@47809
  2394
    equivalent subgoal on the corresponding raw types. Constants are
wenzelm@47809
  2395
    replaced with corresponding ones according to the transfer rules.
wenzelm@47809
  2396
    Goals are generalized over all free variables by default; this is
huffman@47851
  2397
    necessary for variables whose types change, but can be overridden
wenzelm@47855
  2398
    for specific variables with e.g. "transfer fixing: x y z".  The
wenzelm@47809
  2399
    variant transfer' method allows replacing a subgoal with one that
wenzelm@47809
  2400
    is logically stronger (rather than equivalent).
wenzelm@47809
  2401
wenzelm@47809
  2402
  - relator_eq attribute: Collects identity laws for relators of
wenzelm@47809
  2403
    various type constructors, e.g. "list_all2 (op =) = (op =)".  The
wenzelm@47809
  2404
    transfer method uses these lemmas to infer transfer rules for
wenzelm@47809
  2405
    non-polymorphic constants on the fly.
wenzelm@47809
  2406
wenzelm@47809
  2407
  - transfer_prover method: Assists with proving a transfer rule for a
wenzelm@47809
  2408
    new constant, provided the constant is defined in terms of other
wenzelm@47809
  2409
    constants that already have transfer rules. It should be applied
wenzelm@47809
  2410
    after unfolding the constant definitions.
wenzelm@47809
  2411
wenzelm@47809
  2412
  - HOL/ex/Transfer_Int_Nat.thy: Example theory demonstrating transfer
wenzelm@47809
  2413
    from type nat to type int.
wenzelm@47809
  2414
huffman@47851
  2415
* Lifting: New package intended to generalize the quotient_definition
huffman@47851
  2416
facility of the Quotient package; designed to work with Transfer.
wenzelm@47809
  2417
wenzelm@47809
  2418
  - lift_definition command: Defines operations on an abstract type in
wenzelm@47809
  2419
    terms of a corresponding operation on a representation
wenzelm@47809
  2420
    type.  Example syntax:
wenzelm@47809
  2421
wenzelm@47809
  2422
    lift_definition dlist_insert :: "'a => 'a dlist => 'a dlist"
wenzelm@47809
  2423
      is List.insert
wenzelm@47809
  2424
wenzelm@47809
  2425
    Users must discharge a respectfulness proof obligation when each
wenzelm@47809
  2426
    constant is defined. (For a type copy, i.e. a typedef with UNIV,
wenzelm@47809
  2427
    the proof is discharged automatically.) The obligation is
wenzelm@47809
  2428
    presented in a user-friendly, readable form; a respectfulness
wenzelm@47809
  2429
    theorem in the standard format and a transfer rule are generated
wenzelm@47809
  2430
    by the package.
wenzelm@47809
  2431
wenzelm@47809
  2432
  - Integration with code_abstype: For typedefs (e.g. subtypes
wenzelm@47809
  2433
    corresponding to a datatype invariant, such as dlist),
wenzelm@47809
  2434
    lift_definition generates a code certificate theorem and sets up
wenzelm@47809
  2435
    code generation for each constant.
wenzelm@47809
  2436
wenzelm@47809
  2437
  - setup_lifting command: Sets up the Lifting package to work with a
wenzelm@47809
  2438
    user-defined type. The user must provide either a quotient theorem
wenzelm@47809
  2439
    or a type_definition theorem.  The package configures transfer
wenzelm@47809
  2440
    rules for equality and quantifiers on the type, and sets up the
wenzelm@47809
  2441
    lift_definition command to work with the type.
wenzelm@47809
  2442
wenzelm@47809
  2443
  - Usage examples: See Quotient_Examples/Lift_DList.thy,
huffman@47851
  2444
    Quotient_Examples/Lift_RBT.thy, Quotient_Examples/Lift_FSet.thy,
huffman@47851
  2445
    Word/Word.thy and Library/Float.thy.
wenzelm@47809
  2446
wenzelm@47809
  2447
* Quotient package:
wenzelm@47809
  2448
wenzelm@47809
  2449
  - The 'quotient_type' command now supports a 'morphisms' option with
wenzelm@47809
  2450
    rep and abs functions, similar to typedef.
wenzelm@47809
  2451
wenzelm@47809
  2452
  - 'quotient_type' sets up new types to work with the Lifting and
wenzelm@47809
  2453
    Transfer packages, as with 'setup_lifting'.
wenzelm@47809
  2454
wenzelm@47809
  2455
  - The 'quotient_definition' command now requires the user to prove a
wenzelm@47809
  2456
    respectfulness property at the point where the constant is
wenzelm@47809
  2457
    defined, similar to lift_definition; INCOMPATIBILITY.
wenzelm@47809
  2458
wenzelm@47809
  2459
  - Renamed predicate 'Quotient' to 'Quotient3', and renamed theorems
wenzelm@47809
  2460
    accordingly, INCOMPATIBILITY.
wenzelm@47809
  2461
wenzelm@47809
  2462
* New diagnostic command 'find_unused_assms' to find potentially
wenzelm@47809
  2463
superfluous assumptions in theorems using Quickcheck.
wenzelm@47809
  2464
wenzelm@47809
  2465
* Quickcheck:
wenzelm@47809
  2466
wenzelm@47809
  2467
  - Quickcheck returns variable assignments as counterexamples, which
wenzelm@47809
  2468
    allows to reveal the underspecification of functions under test.
wenzelm@47809
  2469
    For example, refuting "hd xs = x", it presents the variable
wenzelm@47809
  2470
    assignment xs = [] and x = a1 as a counterexample, assuming that
wenzelm@47809
  2471
    any property is false whenever "hd []" occurs in it.
wenzelm@47809
  2472
wenzelm@47809
  2473
    These counterexample are marked as potentially spurious, as
wenzelm@47809
  2474
    Quickcheck also returns "xs = []" as a counterexample to the
wenzelm@47809
  2475
    obvious theorem "hd xs = hd xs".
wenzelm@47809
  2476
wenzelm@47809
  2477
    After finding a potentially spurious counterexample, Quickcheck
wenzelm@47809
  2478
    continues searching for genuine ones.
wenzelm@47809
  2479
wenzelm@47809
  2480
    By default, Quickcheck shows potentially spurious and genuine
wenzelm@47809
  2481
    counterexamples. The option "genuine_only" sets quickcheck to only
wenzelm@47809
  2482
    show genuine counterexamples.
wenzelm@47809
  2483
wenzelm@47809
  2484
  - The command 'quickcheck_generator' creates random and exhaustive
wenzelm@47809
  2485
    value generators for a given type and operations.
wenzelm@47809
  2486
wenzelm@47809
  2487
    It generates values by using the operations as if they were
wenzelm@47809
  2488
    constructors of that type.
wenzelm@47809
  2489
wenzelm@47809
  2490
  - Support for multisets.
wenzelm@47809
  2491
wenzelm@47809
  2492
  - Added "use_subtype" options.
wenzelm@47809
  2493
wenzelm@47809
  2494
  - Added "quickcheck_locale" configuration to specify how to process
wenzelm@47809
  2495
    conjectures in a locale context.
wenzelm@47809
  2496
wenzelm@47855
  2497
* Nitpick: Fixed infinite loop caused by the 'peephole_optim' option
wenzelm@47855
  2498
and affecting 'rat' and 'real'.
wenzelm@47809
  2499
wenzelm@47809
  2500
* Sledgehammer:
wenzelm@47809
  2501
  - Integrated more tightly with SPASS, as described in the ITP 2012
wenzelm@47809
  2502
    paper "More SPASS with Isabelle".
wenzelm@47809
  2503
  - Made it try "smt" as a fallback if "metis" fails or times out.
wenzelm@47809
  2504
  - Added support for the following provers: Alt-Ergo (via Why3 and
wenzelm@47809
  2505
    TFF1), iProver, iProver-Eq.
wenzelm@47809
  2506
  - Sped up the minimizer.
wenzelm@47809
  2507
  - Added "lam_trans", "uncurry_aliases", and "minimize" options.
wenzelm@47809
  2508
  - Renamed "slicing" ("no_slicing") option to "slice" ("dont_slice").
wenzelm@47809
  2509
  - Renamed "sound" option to "strict".
wenzelm@47809
  2510
wenzelm@47855
  2511
* Metis: Added possibility to specify lambda translations scheme as a
wenzelm@47855
  2512
parenthesized argument (e.g., "by (metis (lifting) ...)").
wenzelm@47855
  2513
wenzelm@47855
  2514
* SMT: Renamed "smt_fixed" option to "smt_read_only_certificates".
wenzelm@47855
  2515
wenzelm@47855
  2516
* Command 'try0': Renamed from 'try_methods'. INCOMPATIBILITY.
wenzelm@47809
  2517
wenzelm@47856
  2518
* New "case_product" attribute to generate a case rule doing multiple
wenzelm@47856
  2519
case distinctions at the same time.  E.g.
wenzelm@47856
  2520
wenzelm@47856
  2521
  list.exhaust [case_product nat.exhaust]
wenzelm@47856
  2522
wenzelm@47856
  2523
produces a rule which can be used to perform case distinction on both
wenzelm@47856
  2524
a list and a nat.
wenzelm@47856
  2525
wenzelm@47809
  2526
* New "eventually_elim" method as a generalized variant of the
wenzelm@47855
  2527
eventually_elim* rules.  Supports structured proofs.
wenzelm@47855
  2528
wenzelm@47702
  2529
* Typedef with implicit set definition is considered legacy.  Use
wenzelm@47702
  2530
"typedef (open)" form instead, which will eventually become the
wenzelm@47702
  2531
default.
wenzelm@47702
  2532
wenzelm@47856
  2533
* Record: code generation can be switched off manually with
wenzelm@47856
  2534
wenzelm@47856
  2535
  declare [[record_coden = false]]  -- "default true"
wenzelm@47856
  2536
wenzelm@47856
  2537
* Datatype: type parameters allow explicit sort constraints.
wenzelm@47856
  2538
wenzelm@47855
  2539
* Concrete syntax for case expressions includes constraints for source
wenzelm@47855
  2540
positions, and thus produces Prover IDE markup for its bindings.
wenzelm@47855
  2541
INCOMPATIBILITY for old-style syntax translations that augment the
wenzelm@47855
  2542
pattern notation; e.g. see src/HOL/HOLCF/One.thy for translations of
wenzelm@47855
  2543
one_case.
wenzelm@47855
  2544
wenzelm@47855
  2545
* Clarified attribute "mono_set": pure declaration without modifying
wenzelm@47855
  2546
the result of the fact expression.
wenzelm@47855
  2547
haftmann@46752
  2548
* More default pred/set conversions on a couple of relation operations
wenzelm@47464
  2549
and predicates.  Added powers of predicate relations.  Consolidation
wenzelm@47464
  2550

Generalized theorems INF_INT_eq, INF_INT_eq2, SUP_UN_eq, SUP_UN_eq2.
haftmann@46981
  2560
wenzelm@47464
  2561
See theory "Relation" for examples for making use of pred/set
wenzelm@47464

INCOMPATIBILITY.
haftmann@46752
