*** 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.
wenzelm@57946
    16
wenzelm@58801
    17
* Command 'notepad' requires proper nesting of begin/end and its proof
wenzelm@58801
    18
structure in the body: 'oops' is no longer supported here. Minor
wenzelm@58801
    19
INCOMPATIBILITY, use 'sorry' instead.
wenzelm@58801
    20
wenzelm@58928
    21
* Outer syntax commands are managed authentically within the theory
wenzelm@58928
    22
context, without implicit global state.  Potential for accidental
wenzelm@58928
    23
INCOMPATIBILITY, make sure that required theories are really imported.
wenzelm@58928
    24
haftmann@59105
    25
* 'find_theorems': search patterns which are abstractions are
haftmann@59105
    26
schematcially expanded before search.  Search results match the
haftmann@59105
    27
naive expectation more closely, particularly wrt. abbreviations.
haftmann@59105
    28
INCOMPATIBILITY.

    31
*** Prover IDE -- Isabelle/Scala/jEdit ***
wenzelm@58524
    32
wenzelm@58704
    33
* Improved folding mode "isabelle" based on Isar syntax.
wenzelm@58708
    34
Alternatively, the "sidekick" mode may be used for document structure.
wenzelm@58704
    35
wenzelm@58758
    36
* Extended bracket matching based on Isar language structure.  System
wenzelm@58758
    37
option jedit_structure_limit determines maximum number of lines to
wenzelm@58758
    38
scan in the buffer.
wenzelm@58758
    39
wenzelm@58540
    40
* Support for BibTeX files: context menu, context-sensitive token
wenzelm@58540
    41
marker, SideKick parser.
wenzelm@58524
    42
wenzelm@58551
    43
* Document antiquotation @{cite} provides formal markup, which is
wenzelm@58551
    44
interpreted semi-formally based on .bib files that happen to be opened
wenzelm@58592
    45
in the editor (hyperlinks, completion etc.).
wenzelm@58551
    46
wenzelm@58785
    47
* Less waste of vertical space via negative line spacing (see Global
wenzelm@58785
    48
Options / Text Area).
wenzelm@58785

wenzelm@58524

haftmann@58202
    51
*** Pure ***
haftmann@58202
    52
haftmann@58202
    53
* Command "class_deps" takes optional sort arguments constraining
haftmann@58202
    54
the search space.
haftmann@58202
    55
haftmann@58410
    56
* Lexical separation of signed and unsigend numerals: categories "num"
haftmann@58410
    57
and "float" are unsigend.  INCOMPATIBILITY: subtle change in precedence
haftmann@58410
    58
of numeral signs, particulary in expressions involving infix syntax like
haftmann@58410
    59
"(- 1) ^ n".
haftmann@58410
    60
wenzelm@58421
    61
* Old inner token category "xnum" has been discontinued.  Potential
wenzelm@58421
    62
INCOMPATIBILITY for exotic syntax: may use mixfix grammar with "num"
wenzelm@58421
    63
token category instead.
wenzelm@58421

blanchet@57737
    66
*** HOL ***
blanchet@57737
    67
hoelzl@58775
    68
* Add NO_MATCH-simproc, allows to check for syntactic non-equality
hoelzl@58775
    69
haftmann@58649
    70
* Generalized and consolidated some theorems concerning divsibility:
haftmann@58649
    71
  dvd_reduce ~> dvd_add_triv_right_iff
haftmann@58649
    72
  dvd_plus_eq_right ~> dvd_add_right_iff
haftmann@58649
    73
  dvd_plus_eq_left ~> dvd_add_left_iff
haftmann@58649
    74
Minor INCOMPATIBILITY.
haftmann@58649
    75
haftmann@58770
    76
* "even" and "odd" are mere abbreviations for "2 dvd _" and "~ 2 dvd _"
haftmann@58770
    77
and part of HOL-Main.
haftmann@58645
    78
  even_def ~> even_iff_mod_2_eq_zero
haftmann@58740
    79
INCOMPATIBILITY.
haftmann@58645
    80
haftmann@58512
    81
* Lemma name consolidation: divide_Numeral1 ~> divide_numeral_1
haftmann@58512
    82
Minor INCOMPATIBILITY.
haftmann@58512
    83
hoelzl@58776
    84
* field_simps: Use NO_MATCH-simproc for distribution rules, to avoid
hoelzl@58776
    85
  non-termination in case of distributing a division. With this change
hoelzl@58776
    86
  field_simps is in some cases slightly less powerful, if it fails try
hoelzl@58776
    87
  to add algebra_simps, or use divide_simps.
hoelzl@58776
    88
Minor INCOMPATIBILITY.
hoelzl@58776
    89
haftmann@58321
    90
* Bootstrap of listsum as special case of abstract product over lists.
haftmann@58321
    91
Fact rename:
haftmann@58321
    92
    listsum_def ~> listsum.eq_foldr
haftmann@58321
    93
INCOMPATIBILITY.
haftmann@58321
    94
haftmann@58100
    95
* Command and antiquotation "value" provide different evaluation slots (again),
haftmann@58100
    96
where the previous strategy (nbe after ML) serves as default.
haftmann@58100
    97
Minor INCOMPATIBILITY.
haftmann@58100
    98
blanchet@57983
    99
* New (co)datatype package:
blanchet@58373
   100
  - The 'datatype_new' command has been renamed 'datatype'. The old
blanchet@58373
   101
    command of that name is now called 'old_datatype' and is provided
blanchet@58373
   102
    by "~~/src/HOL/Library/Old_Datatype.thy". See
blanchet@58373
   103
    'isabelle doc datatypes' for information on porting.
blanchet@58373
   104
    INCOMPATIBILITY.
blanchet@57983
   105
  - Renamed theorems:
blanchet@57983
   106
      disc_corec ~> corec_disc
blanchet@57983
   107
      disc_corec_iff ~> corec_disc_iff
blanchet@57983
   108
      disc_exclude ~> distinct_disc
blanchet@57983
   109
      disc_exhaust ~> exhaust_disc
blanchet@57983
   110
      disc_map_iff ~> map_disc_iff
blanchet@57983
   111
      sel_corec ~> corec_sel
blanchet@57983
   112
      sel_exhaust ~> exhaust_sel
blanchet@57983
   113
      sel_map ~> map_sel
blanchet@57983
   114
      sel_set ~> set_sel
blanchet@57983
   115
      sel_split ~> split_sel
blanchet@57983
   116
      sel_split_asm ~> split_sel_asm
blanchet@57983
   117
      strong_coinduct ~> coinduct_strong
blanchet@57983
   118
      weak_case_cong ~> case_cong_weak
blanchet@57983
   119
    INCOMPATIBILITY.
blanchet@58192
   120
  - The "no_code" option to "free_constructors", "datatype_new", and
blanchet@58192
   121
    "codatatype" has been renamed "plugins del: code".
blanchet@58192
   122
    INCOMPATIBILITY.
blanchet@58044
   123
  - The rules "set_empty" have been removed. They are easy
blanchet@58044
   124
    consequences of other set rules "by auto".
blanchet@58044
   125
    INCOMPATIBILITY.
blanchet@58044
   126
  - The rule "set_cases" is now registered with the "[cases set]"
blanchet@57990
   127
    attribute. This can influence the behavior of the "cases" proof
blanchet@57990
   128
    method when more than one case rule is applicable (e.g., an
blanchet@57990
   129
    assumption is of the form "w : set ws" and the method "cases w"
blanchet@57990
   130
    is invoked). The solution is to specify the case rule explicitly
blanchet@57990
   131
    (e.g. "cases w rule: widget.exhaust").
blanchet@57990
   132
    INCOMPATIBILITY.
blanchet@57983
   133
blanchet@57983
   134
* Old datatype package:
blanchet@58310
   135
  - The old 'datatype' command has been renamed 'old_datatype', and
blanchet@58373
   136
    'rep_datatype' has been renamed 'old_rep_datatype'. They are
blanchet@58373
   137
    provided by "~~/src/HOL/Library/Old_Datatype.thy". See
blanchet@58310
   138
    'isabelle doc datatypes' for information on porting.
blanchet@58373
   139
    INCOMPATIBILITY.
blanchet@57983
   140
  - Renamed theorems:
blanchet@57983
   141
      weak_case_cong ~> case_cong_weak
blanchet@57983
   142
    INCOMPATIBILITY.
blanchet@58373
   143
  - Renamed theory:
blanchet@58373
   144
      ~~/src/HOL/Datatype.thy ~> ~~/src/HOL/Library/Old_Datatype.thy
blanchet@58373
   145
    INCOMPATIBILITY.
blanchet@57983
   146
haftmann@58368
   147
* Product over lists via constant "listprod".
haftmann@58368
   148
blanchet@59039
   149
* Nitpick:
blanchet@59039
   150
  - Fixed soundness bug related to the strict and nonstrict subset
blanchet@59039
   151
    operations.
blanchet@59039
   152
blanchet@57737
   153
* Sledgehammer:
blanchet@57737
   154
  - Minimization is now always enabled by default.
blanchet@57737
   155
    Removed subcommand:
blanchet@57737
   156
      min
blanchet@59039
   157
  - The proof reconstruction, both one-liners and Isar, has been
blanchet@59039
   158
    dramatically improved.
blanchet@59039
   159
  - Improved support for CVC4 and veriT.
blanchet@57737
   160
blanchet@58062
   161
* Old and new SMT modules:
blanchet@58067
   162
  - The old 'smt' method has been renamed 'old_smt' and moved to
blanchet@58060
   163
    'src/HOL/Library/Old_SMT.thy'. It provided for compatibility, until
blanchet@58067
   164
    applications have been ported to use the new 'smt' method. For the
blanchet@58067
   165
    method to work, an older version of Z3 (e.g. Z3 3.2 or 4.0) must be
blanchet@58062
   166
    installed, and the environment variable "OLD_Z3_SOLVER" must point to
blanchet@58062
   167
    it.
blanchet@58062
   168
    INCOMPATIBILITY.
blanchet@58067
   169
  - The 'smt2' method has been renamed 'smt'.
blanchet@58060
   170
    INCOMPATIBILITY.
blanchet@58060
   171
nipkow@58247
   172
* List: renamed drop_Suc_conv_tl and nth_drop' to Cons_nth_drop_Suc
nipkow@58247
   173
Andreas@58626
   174
* New infrastructure for compiling, running, evaluating and testing
Andreas@58626
   175
  generated code in target languages in HOL/Library/Code_Test. See
Andreas@58626
   176
  HOL/Codegenerator_Test/Code_Test* for examples.
wenzelm@58008
   177
wenzelm@58630
   178
* Library/Sum_of_Squares: simplified and improved "sos" method. Always
wenzelm@58630
   179
use local CSDP executable, which is much faster than the NEOS server.
wenzelm@58630
   180
The "sos_cert" functionality is invoked as "sos" with additional
wenzelm@58630
   181
argument. Minor INCOMPATIBILITY.
wenzelm@58630
   182
immler@58990
   183
* HOL-Decision_Procs:
immler@58990
   184
  - New counterexample generator quickcheck[approximation] for
immler@58990
   185
    inequalities of transcendental functions.
immler@58990
   186
    Uses hardware floating point arithmetic to randomly discover
immler@58990
   187
    potential counterexamples. Counterexamples are certified with the
immler@58990
   188
    'approximation' method.
immler@58990
   189
    See HOL/Decision_Procs/ex/Approximation_Quickcheck_Ex.thy for
immler@58990
   190
    examples.
immler@58990

wenzelm@58716
   193
*** Document preparation ***
wenzelm@58716
   194
wenzelm@58999
   195
* Document markup commands 'chapter', 'section', 'subsection',
wenzelm@58999
   196
'subsubsection', 'text', 'txt', 'text_raw' work uniformly in any
wenzelm@58999
   197
context, even before the initial 'theory' command. Obsolete proof
wenzelm@58999
   198
commands 'sect', 'subsect', 'subsubsect', 'txt_raw' have been
wenzelm@58999
   199
discontinued, use 'section', 'subsection', 'subsubsection', 'text_raw'
wenzelm@58999
   200
instead. The old 'header' command is still retained for some time, but
wenzelm@58999
   201
should be replaced by 'chapter', 'section' etc. (using "isabelle
wenzelm@58999
   202
update_header"). Minor INCOMPATIBILITY.
wenzelm@58999
   203
wenzelm@58999
   204
* Diagnostic commands and document markup commands within a proof do not
wenzelm@58999
   205
affect the command tag for output. Thus commands like 'thm' are subject
wenzelm@58999
   206
to proof document structure, and no longer "stick out" accidentally.
wenzelm@58999
   207
Commands 'text' and 'txt' merely differ in the LaTeX style, not their
wenzelm@58999
   208
tags. Potential INCOMPATIBILITY in exotic situations.
wenzelm@58868
   209
wenzelm@58716
   210
* Official support for "tt" style variants, via \isatt{...} or
wenzelm@58716
   211
\begin{isabellett}...\end{isabellett}. The somewhat fragile \verb or
wenzelm@58716
   212
verbatim environment of LaTeX is no longer used. This allows @{ML} etc.
wenzelm@58716
   213
as argument to other macros (such as footnotes).
wenzelm@58716
   214
wenzelm@58716
   215
* Document antiquotation @{verbatim} prints ASCII text literally in "tt"
wenzelm@58716
   216
style.
wenzelm@58716
   217
wenzelm@58716
   218
blanchet@58066
   219
*** ML ***
blanchet@58066
   220
wenzelm@59180
   221
* Former combinators NAMED_CRITICAL and CRITICAL for central critical
wenzelm@59180
   222
sections have been discontinued, in favour of the more elementary
wenzelm@59180
   223
Multithreading.synchronized and its high-level derivative
wenzelm@59180
   224
Synchronized.var (which is usually sufficient in applications). Subtle
wenzelm@59180
   225
INCOMPATIBILITY: synchronized access needs to be atomic and cannot be
wenzelm@59180
   226
nested.
wenzelm@59180
   227
wenzelm@59112
   228
* Cartouches within ML sources are turned into values of type
wenzelm@59112
   229
Input.source (with formal position information).
wenzelm@59112
   230
wenzelm@58963
   231
* Proper context for various elementary tactics: assume_tac,
wenzelm@58963
   232
match_tac, compose_tac, Splitter.split_tac etc.  Minor
wenzelm@58963
   233
INCOMPATIBILITY.
wenzelm@58956
   234
blanchet@58066
   235
* Tactical PARALLEL_ALLGOALS is the most common way to refer to
blanchet@58066
   236
PARALLEL_GOALS.
blanchet@58066
   237
wenzelm@59057
   238
* Basic combinators map, fold, fold_map, split_list, apply are
wenzelm@59057
   239
available as parameterized antiquotations, e.g. @{map 4} for lists of
wenzelm@59057
   240
quadruples.
wenzelm@58634
   241
wenzelm@59058
   242
* Renamed "pairself" to "apply2", in accordance to @{apply 2}.
wenzelm@59058
   243
INCOMPATIBILITY.
wenzelm@59058
   244
wenzelm@59139
   245
* Synchronized.value (ML) is actually synchronized (as in Scala):
wenzelm@59139
   246
subtle change of semantics with minimal potential for INCOMPATIBILITY.
wenzelm@59139
   247
blanchet@58066

wenzelm@58610
   249
*** System ***
wenzelm@58610
   250
wenzelm@58846
   251
* Support for Proof General and Isar TTY loop has been discontinued.
wenzelm@58846
   252
Minor INCOMPATIBILITY.
wenzelm@58842
   253
wenzelm@59200
   254
* JVM system property "isabelle.threads" determines size of Scala thread
wenzelm@59200
   255
pool, like Isabelle system option "threads" for ML.
wenzelm@59200
   256
wenzelm@59175
   257
* System option "pretty_margin" is superseded by "thy_output_margin",
wenzelm@59175
   258
which is also accessible via document antiquotation option "margin".
wenzelm@59175
   259
Only the margin for document output may be changed, but not the global
wenzelm@59175
   260
pretty printing: that is 76 for plain console output, and adapted
wenzelm@59175
   261
dynamically in GUI front-ends. Implementations of document
wenzelm@59175
   262
antiquotations need to observe the margin explicitly according to
wenzelm@59175
   263
Thy_Output.string_of_margin. Minor INCOMPATIBILITY.
wenzelm@59175
   264
wenzelm@58861
   265
* Historical command-line terminator ";" is no longer accepted.  Minor
wenzelm@58861
   266
INCOMPATIBILITY, use "isabelle update_semicolons" to remove obsolete
wenzelm@58861
   267
semicolons from theory sources.
wenzelm@58861
   268
wenzelm@58610
   269
* The Isabelle tool "update_cartouches" changes theory files to use
wenzelm@58610
   270
cartouches instead of old-style {* verbatim *} or `alt_string` tokens.
wenzelm@58610
   271

   277
*** General ***
wenzelm@54702
   278
wenzelm@57452
   279
* Support for official Standard ML within the Isabelle context.
wenzelm@57452
   280
Command 'SML_file' reads and evaluates the given Standard ML file.
wenzelm@57452
   281
Toplevel bindings are stored within the theory context; the initial
wenzelm@57452
   282
environment is restricted to the Standard ML implementation of
wenzelm@57452
   283
Poly/ML, without the add-ons of Isabelle/ML.  Commands 'SML_import'
wenzelm@57452
   284
and 'SML_export' allow to exchange toplevel bindings between the two
wenzelm@57452
   285
separate environments.  See also ~~/src/Tools/SML/Examples.thy for
wenzelm@57452
   286
some examples.
wenzelm@56499
   287
wenzelm@57504
   288
* Standard tactics and proof methods such as "clarsimp", "auto" and
wenzelm@57504
   289
"safe" now preserve equality hypotheses "x = expr" where x is a free
wenzelm@57504
   290
variable.  Locale assumptions and chained facts containing "x"
wenzelm@57504
   291
continue to be useful.  The new method "hypsubst_thin" and the
wenzelm@57504
   292
configuration option "hypsubst_thin" (within the attribute name space)
wenzelm@57504
   293
restore the previous behavior.  INCOMPATIBILITY, especially where
wenzelm@57504
   294
induction is done after these methods or when the names of free and
wenzelm@57504
   295
bound variables clash.  As first approximation, old proofs may be
wenzelm@57504
   296
repaired by "using [[hypsubst_thin = true]]" in the critical spot.
wenzelm@57504
   297
wenzelm@56232
   298
* More static checking of proof methods, which allows the system to
wenzelm@56232
   299
form a closure over the concrete syntax.  Method arguments should be
wenzelm@56232
   300
processed in the original proof context as far as possible, before
wenzelm@56232
   301
operating on the goal state.  In any case, the standard discipline for
wenzelm@56232
   302
subgoal-addressing needs to be observed: no subgoals or a subgoal
wenzelm@56232
   303
number that is out of range produces an empty result sequence, not an
wenzelm@56232
   304
exception.  Potential INCOMPATIBILITY for non-conformant tactical
wenzelm@56232
   305
proof tools.
wenzelm@56232
   306
wenzelm@57452
   307
* Lexical syntax (inner and outer) supports text cartouches with
wenzelm@57452
   308
arbitrary nesting, and without escapes of quotes etc.  The Prover IDE
wenzelm@57452
   309
supports input via ` (backquote).
wenzelm@57452
   310
wenzelm@57452
   311
* The outer syntax categories "text" (for formal comments and document
wenzelm@57452
   312
markup commands) and "altstring" (for literal fact references) allow
wenzelm@57452
   313
cartouches as well, in addition to the traditional mix of quotations.
wenzelm@57452
   314
wenzelm@57452
   315
* Syntax of document antiquotation @{rail} now uses \<newline> instead
wenzelm@57452
   316
of "\\", to avoid the optical illusion of escaped backslash within
wenzelm@57491
   317
string token.  General renovation of its syntax using text cartouches.
wenzelm@57452
   318
Minor INCOMPATIBILITY.
wenzelm@57452
   319
wenzelm@57452
   320
* Discontinued legacy_isub_isup, which was a temporary workaround for
wenzelm@57452
   321
Isabelle/ML in Isabelle2013-1.  The prover process no longer accepts
wenzelm@57452
   322
old identifier syntax with \<^isub> or \<^isup>.  Potential
wenzelm@57452
   323
INCOMPATIBILITY.
wenzelm@57452
   324
wenzelm@57452
   325
* Document antiquotation @{url} produces markup for the given URL,
wenzelm@57452
   326
which results in an active hyperlink within the text.
wenzelm@57452
   327
wenzelm@57452
   328
* Document antiquotation @{file_unchecked} is like @{file}, but does
wenzelm@57452
   329
not check existence within the file-system.
wenzelm@57452
   330
wenzelm@57452
   331
* Updated and extended manuals: codegen, datatypes, implementation,
wenzelm@57452
   332
isar-ref, jedit, system.
wenzelm@57423
   333
wenzelm@54702
   334
wenzelm@54533
   335
*** Prover IDE -- Isabelle/Scala/jEdit ***
wenzelm@54533
   336
wenzelm@57650
   337
* Improved Document panel: simplified interaction where every single
wenzelm@57452
   338
mouse click (re)opens document via desktop environment or as jEdit
wenzelm@57452
   339
buffer.
wenzelm@57452
   340
wenzelm@57452
   341
* Support for Navigator plugin (with toolbar buttons), with connection
wenzelm@57452
   342
to PIDE hyperlinks.
wenzelm@57452
   343
wenzelm@57452
   344
* Auxiliary files ('ML_file' etc.) are managed by the Prover IDE.
wenzelm@57452
   345
Open text buffers take precedence over copies within the file-system.
wenzelm@57452
   346
wenzelm@57452
   347
* Improved support for Isabelle/ML, with jEdit mode "isabelle-ml" for
wenzelm@57452
   348
auxiliary ML files.
wenzelm@57423
   349
wenzelm@57423
   350
* Improved syntactic and semantic completion mechanism, with simple
wenzelm@57423
   351
templates, completion language context, name-space completion,
wenzelm@57423
   352
file-name completion, spell-checker completion.
wenzelm@57423
   353
wenzelm@57423
   354
* Refined GUI popup for completion: more robust key/mouse event
wenzelm@57423
   355
handling and propagation to enclosing text area -- avoid loosing
wenzelm@57423
   356
keystrokes with slow / remote graphics displays.
wenzelm@57423
   357
wenzelm@57833
   358
* Completion popup supports both ENTER and TAB (default) to select an
wenzelm@57833
   359
item, depending on Isabelle options.
wenzelm@57833
   360
wenzelm@57423
   361
* Refined insertion of completion items wrt. jEdit text: multiple
wenzelm@57423
   362
selections, rectangular selections, rectangular selection as "tall
wenzelm@57423
   363
caret".
wenzelm@56342
   364
wenzelm@56580
   365
* Integrated spell-checker for document text, comments etc. with
wenzelm@57423
   366
completion popup and context-menu.
wenzelm@56554
   367
wenzelm@56879
   368
* More general "Query" panel supersedes "Find" panel, with GUI access
wenzelm@56879
   369
to commands 'find_theorems' and 'find_consts', as well as print
wenzelm@56879
   370
operations for the context.  Minor incompatibility in keyboard
wenzelm@56879
   371
shortcuts etc.: replace action isabelle-find by isabelle-query.
wenzelm@56761
   372
wenzelm@56901
   373
* Search field for all output panels ("Output", "Query", "Info" etc.)
wenzelm@56901
   374
to highlight text via regular expression.
wenzelm@56901
   375
wenzelm@54881
   376
* Option "jedit_print_mode" (see also "Plugin Options / Isabelle /
wenzelm@54881
   377
General") allows to specify additional print modes for the prover
wenzelm@54881
   378
process, without requiring old-fashioned command-line invocation of
wenzelm@54881
   379
"isabelle jedit -m MODE".
wenzelm@54881
   380
wenzelm@56505
   381
* More support for remote files (e.g. http) using standard Java
wenzelm@56505
   382
networking operations instead of jEdit virtual file-systems.
wenzelm@56505
   383
wenzelm@57822
   384
* Empty editors buffers that are no longer required (e.g.\ via theory
wenzelm@57822
   385
imports) are automatically removed from the document model.
wenzelm@57822
   386
wenzelm@57869
   387
* Improved monitor panel.
wenzelm@57869
   388
wenzelm@56838
   389
* Improved Console/Scala plugin: more uniform scala.Console output,
wenzelm@56838
   390
more robust treatment of threads and interrupts.
wenzelm@56838
   391
wenzelm@56939
   392
* Improved management of dockable windows: clarified keyboard focus
wenzelm@56939
   393
and window placement wrt. main editor view; optional menu item to
wenzelm@56939
   394
"Detach" a copy where this makes sense.
wenzelm@56939
   395
wenzelm@57452
   396
* New Simplifier Trace panel provides an interactive view of the
wenzelm@57591
   397
simplification process, enabled by the "simp_trace_new" attribute
wenzelm@57452
   398
within the context.
wenzelm@57452

wenzelm@55001
   401
*** Pure ***
wenzelm@55001
   402
wenzelm@57504
   403
* Low-level type-class commands 'classes', 'classrel', 'arities' have
wenzelm@57504
   404
been discontinued to avoid the danger of non-trivial axiomatization
wenzelm@57504
   405
that is not immediately visible.  INCOMPATIBILITY, use regular
wenzelm@57504
   406
'instance' command with proof.  The required OFCLASS(...) theorem
wenzelm@57504
   407
might be postulated via 'axiomatization' beforehand, or the proof
wenzelm@57504
   408
finished trivially if the underlying class definition is made vacuous
wenzelm@57504
   409
(without any assumptions).  See also Isabelle/ML operations
wenzelm@57504
   410
Axclass.class_axiomatization, Axclass.classrel_axiomatization,
wenzelm@57504
   411
Axclass.arity_axiomatization.
wenzelm@57504
   412
wenzelm@56245
   413
* Basic constants of Pure use more conventional names and are always
wenzelm@56245
   414
qualified.  Rare INCOMPATIBILITY, but with potentially serious
wenzelm@56245
   415
consequences, notably for tools in Isabelle/ML.  The following
wenzelm@56245
   416
renaming needs to be applied:
wenzelm@56245
   417
wenzelm@56245
   418
  ==             ~>  Pure.eq
wenzelm@56245
   419
  ==>            ~>  Pure.imp
wenzelm@56245
   420
  all            ~>  Pure.all
wenzelm@56245
   421
  TYPE           ~>  Pure.type
wenzelm@56245
   422
  dummy_pattern  ~>  Pure.dummy_pattern
wenzelm@56245
   423
wenzelm@56245
   424
Systematic porting works by using the following theory setup on a
wenzelm@56245
   425
*previous* Isabelle version to introduce the new name accesses for the
wenzelm@56245
   426
old constants:
wenzelm@56245
   427
wenzelm@56245
   428
setup {*
wenzelm@56245
   429
  fn thy => thy
wenzelm@56245
   430
    |> Sign.root_path
wenzelm@56245
   431
    |> Sign.const_alias (Binding.qualify true "Pure" @{binding eq}) "=="
wenzelm@56245
   432
    |> Sign.const_alias (Binding.qualify true "Pure" @{binding imp}) "==>"
wenzelm@56245
   433
    |> Sign.const_alias (Binding.qualify true "Pure" @{binding all}) "all"
wenzelm@56245
   434
    |> Sign.restore_naming thy
wenzelm@56245
   435
*}
wenzelm@56245
   436
wenzelm@56245
   437
Thus ML antiquotations like @{const_name Pure.eq} may be used already.
wenzelm@56245
   438
Later the application is moved to the current Isabelle version, and
wenzelm@56245
   439
the auxiliary aliases are deleted.
wenzelm@56245
   440
wenzelm@55143
   441
* Attributes "where" and "of" allow an optional context of local
wenzelm@55143
   442
variables ('for' declaration): these variables become schematic in the
wenzelm@55143
   443
instantiated theorem.
wenzelm@55143
   444
wenzelm@55152
   445
* Obsolete attribute "standard" has been discontinued (legacy since
wenzelm@55152
   446
Isabelle2012).  Potential INCOMPATIBILITY, use explicit 'for' context
wenzelm@55152
   447
where instantiations with schematic variables are intended (for
wenzelm@55152
   448
declaration commands like 'lemmas' or attributes like "of").  The
wenzelm@55152
   449
following temporary definition may help to port old applications:
wenzelm@55152
   450
wenzelm@55152
   451
  attribute_setup standard =
wenzelm@55152
   452
    "Scan.succeed (Thm.rule_attribute (K Drule.export_without_context))"
wenzelm@55152
   453
wenzelm@55001
   454
* More thorough check of proof context for goal statements and
wenzelm@55006
   455
attributed fact expressions (concerning background theory, declared
wenzelm@55006
   456
hyps).  Potential INCOMPATIBILITY, tools need to observe standard
wenzelm@55006
   457
context discipline.  See also Assumption.add_assumes and the more
wenzelm@55006
   458
primitive Thm.assume_hyps.
wenzelm@55001
   459
wenzelm@55108
   460
* Inner syntax token language allows regular quoted strings "..."
wenzelm@55108
   461
(only makes sense in practice, if outer syntax is delimited
wenzelm@57452
   462
differently, e.g. via cartouches).
wenzelm@57452
   463
wenzelm@57504
   464
* Command 'print_term_bindings' supersedes 'print_binds' for clarity,
wenzelm@57504
   465
but the latter is retained some time as Proof General legacy.
wenzelm@57504
   466
wenzelm@57452
   467
* Code generator preprocessor: explicit control of simp tracing on a
wenzelm@57452
   468
per-constant basis.  See attribute "code_preproc".

haftmann@54227
   471
*** HOL ***
haftmann@54227
   472
wenzelm@57504
   473
* Code generator: enforce case of identifiers only for strict target
wenzelm@57504
   474
language requirements.  INCOMPATIBILITY.
wenzelm@57504
   475
wenzelm@57504
   476
* Code generator: explicit proof contexts in many ML interfaces.
wenzelm@57504
   477
INCOMPATIBILITY.
wenzelm@57504
   478
wenzelm@57504
   479
* Code generator: minimize exported identifiers by default.  Minor
wenzelm@57504
   480
INCOMPATIBILITY.
wenzelm@57504
   481
wenzelm@57504
   482
* Code generation for SML and OCaml: dropped arcane "no_signatures"
wenzelm@57504
   483
option.  Minor INCOMPATIBILITY.
wenzelm@57504
   484
wenzelm@57504
   485
* "declare [[code abort: ...]]" replaces "code_abort ...".
wenzelm@57504
   486
INCOMPATIBILITY.
wenzelm@57504
   487
wenzelm@57504
   488
* "declare [[code drop: ...]]" drops all code equations associated
wenzelm@57504
   489
with the given constants.
wenzelm@57504
   490
wenzelm@57504
   491
* Code generations are provided for make, fields, extend and truncate
wenzelm@57504
   492
operations on records.
haftmann@57437
   493
wenzelm@57452
   494
* Command and antiquotation "value" are now hardcoded against nbe and
wenzelm@57452
   495
ML.  Minor INCOMPATIBILITY.
wenzelm@57452
   496
wenzelm@57504
   497
* Renamed command 'enriched_type' to 'functor'. INCOMPATIBILITY.
wenzelm@57504
   498
wenzelm@57504
   499
* The symbol "\<newline>" may be used within char or string literals
wenzelm@57504
   500
to represent (Char Nibble0 NibbleA), i.e. ASCII newline.
wenzelm@57504
   501
wenzelm@57504
   502
* Qualified String.implode and String.explode.  INCOMPATIBILITY.
haftmann@56923
   503
wenzelm@57452
   504
* Simplifier: Enhanced solver of preconditions of rewrite rules can
wenzelm@57452
   505
now deal with conjunctions.  For help with converting proofs, the old
wenzelm@57452
   506
behaviour of the simplifier can be restored like this: declare/using
wenzelm@57452
   507
[[simp_legacy_precond]].  This configuration option will disappear
wenzelm@57452
   508
again in the future.  INCOMPATIBILITY.
nipkow@56073
   509
wenzelm@55139
   510
* Simproc "finite_Collect" is no longer enabled by default, due to
wenzelm@55139
   511
spurious crashes and other surprises.  Potential INCOMPATIBILITY.
wenzelm@55139
   512
wenzelm@57452
   513
* Moved new (co)datatype package and its dependencies from session
wenzelm@57452
   514
  "HOL-BNF" to "HOL".  The commands 'bnf', 'wrap_free_constructors',
wenzelm@57452
   515
  'datatype_new', 'codatatype', 'primcorec', 'primcorecursive' are now
wenzelm@57452
   516
  part of theory "Main".

* New (co)datatype package:
wenzelm@57452
   556
  - Command 'primcorec' is fully implemented.
wenzelm@57452
   557
  - Command 'datatype_new' generates size functions ("size_xxx" and
wenzelm@57452
   558
    "size") as required by 'fun'.
wenzelm@57452
   559
  - BNFs are integrated with the Lifting tool and new-style
wenzelm@57452
   560
    (co)datatypes with Transfer.

blanchet@55875
   568
    INCOMPATIBILITY.
wenzelm@57452
   569
  - The constant "xxx_(un)fold" and related theorems are no longer

    default, eliminating the need for the odd "=:" syntax.
blanchet@57091
   575
    INCOMPATIBILITY.
wenzelm@57452
   576
  - No discriminators or selectors are generated by default by

  - The generated theorems "xxx.cases" and "xxx.recs" have been
wenzelm@57452
   583
    renamed "xxx.case" and "xxx.rec" (e.g., "sum.cases" ->
wenzelm@57452
   584
    "sum.case").  INCOMPATIBILITY.
wenzelm@57452
   585
  - The generated constants "xxx_case", "xxx_rec", and "xxx_size" have
wenzelm@57452
   586
    been renamed "case_xxx", "rec_xxx", and "size_xxx" (e.g.,

* Lifting and Transfer:
kuncar@57826
   627
  - a type variable as a raw type is supported
kuncar@57826
   628
  - stronger reflexivity prover
kuncar@57826
   629
  - rep_eq is always generated by lift_definition

kuncar@57826
   645
      INCOMPATIBILITY.
wenzelm@57856
   646
    + Domainp does not have to be a separate assumption in

      relator_domain theorems (=> more natural statement)
kuncar@57826
   648
      INCOMPATIBILITY.
kuncar@57826

   661
wenzelm@57508
   662
* New internal SAT solver "cdclite" that produces models and proof
wenzelm@57508
   663
traces.  This solver replaces the internal SAT solvers "enumerate" and
wenzelm@57508
   664
"dpll".  Applications that explicitly used one of these two SAT
wenzelm@57508
   665
solvers should use "cdclite" instead. In addition, "cdclite" is now
wenzelm@57508
   666
the default SAT solver for the "sat" and "satx" proof methods and
wenzelm@57508
   667
corresponding tactics; the old default can be restored using "declare
wenzelm@57508
   668
[[sat_solver = zchaff_with_proofs]]".  Minor INCOMPATIBILITY.
wenzelm@57508
   669
wenzelm@57508
   670
* SMT module: A new version of the SMT module, temporarily called
wenzelm@57508
   671
"SMT2", uses SMT-LIB 2 and supports recent versions of Z3 (e.g.,
wenzelm@57508
   672
4.3). The new proof method is called "smt2". CVC3 and CVC4 are also
wenzelm@57508
   673
supported as oracles. Yices is no longer supported, because no version
wenzelm@57508
   674
of the solver can handle both SMT-LIB 2 and quantifiers.
wenzelm@57508
   675
wenzelm@57508
   676
* Activation of Z3 now works via "z3_non_commercial" system option
wenzelm@57508
   677
(without requiring restart), instead of former settings variable
wenzelm@57508
   678
"Z3_NON_COMMERCIAL".  The option can be edited in Isabelle/jEdit menu
wenzelm@57508
   679
Plugin Options / Isabelle / General.
wenzelm@57508
   680
wenzelm@57508
   681
* Sledgehammer:
wenzelm@57508
   682
  - Z3 can now produce Isar proofs.
wenzelm@57508
   683
  - MaSh overhaul:
blanchet@57532
   684
    . New SML-based learning algorithms eliminate the dependency on
wenzelm@57508
   685
      Python and increase performance and reliability.
wenzelm@57508
   686
    . MaSh and MeSh are now used by default together with the
wenzelm@57508
   687
      traditional MePo (Meng-Paulson) relevance filter. To disable
wenzelm@57508
   688
      MaSh, set the "MaSh" system option in Isabelle/jEdit Plugin
wenzelm@57508
   689
      Options / Isabelle / General to "none".
wenzelm@57508
   690
  - New option:
wenzelm@57508
   691
      smt_proofs
wenzelm@57508
   692
  - Renamed options:
wenzelm@57508
   693
      isar_compress ~> compress
wenzelm@57508
   694
      isar_try0 ~> try0
wenzelm@57508

wenzelm@57508
   696
INCOMPATIBILITY.
wenzelm@57508
   697
wenzelm@57508
   698
* Removed solvers remote_cvc3 and remote_z3. Use cvc3 and z3 instead.
wenzelm@57508
   699
wenzelm@57508
   700
* Nitpick:
wenzelm@57508
   701
  - Fixed soundness bug whereby mutually recursive datatypes could
wenzelm@57508
   702
    take infinite values.
wenzelm@57508
   703
  - Fixed soundness bug with low-level number functions such as
wenzelm@57508
   704
    "Abs_Integ" and "Rep_Integ".
wenzelm@57508
   705
  - Removed "std" option.
wenzelm@57508
   706
  - Renamed "show_datatypes" to "show_types" and "hide_datatypes" to
wenzelm@57508
   707
    "hide_types".
wenzelm@57508
   708
wenzelm@57508
   709
* Metis: Removed legacy proof method 'metisFT'. Use 'metis
wenzelm@57508
   710
(full_types)' instead. INCOMPATIBILITY.
wenzelm@57508
   711
wenzelm@57508
   712
* Try0: Added 'algebra' and 'meson' to the set of proof methods.
wenzelm@57508
   713
wenzelm@57508
   714
* Adjustion of INF and SUP operations:
wenzelm@57508
   715
  - Elongated constants INFI and SUPR to INFIMUM and SUPREMUM.
wenzelm@57508
   716
  - Consolidated theorem names containing INFI and SUPR: have INF and
wenzelm@57508
   717
    SUP instead uniformly.
wenzelm@57508
   718
  - More aggressive normalization of expressions involving INF and Inf
wenzelm@57508
   719
    or SUP and Sup.
wenzelm@57508
   720
  - INF_image and SUP_image do not unfold composition.
wenzelm@57508
   721
  - Dropped facts INF_comp, SUP_comp.
wenzelm@57508
   722
  - Default congruence rules strong_INF_cong and strong_SUP_cong, with
wenzelm@57508
   723
    simplifier implication in premises.  Generalize and replace former
wenzelm@57508
   724
    INT_cong, SUP_cong
wenzelm@57508
   725
wenzelm@57508
   726
INCOMPATIBILITY.
wenzelm@57508
   727
wenzelm@57508
   728
* SUP and INF generalized to conditionally_complete_lattice.
wenzelm@57508
   729
wenzelm@57508
   730
* Swapped orientation of facts image_comp and vimage_comp:
wenzelm@57508
   731
wenzelm@57508
   732
  image_compose ~> image_comp [symmetric]
wenzelm@57508

   737
INCOMPATIBILITY.
wenzelm@57508
   738
wenzelm@57504
   739
* Theory reorganization: split of Big_Operators.thy into

   740
Groups_Big.thy and Lattices_Big.thy.
blanchet@55098

  1278
wenzelm@57504
  1279
* Proper context discipline for read_instantiate and instantiate_tac:
wenzelm@57504
  1280
variables that are meant to become schematic need to be given as
wenzelm@57504
  1281
fixed, and are generalized by the explicit context of local variables.
wenzelm@57504
  1282
This corresponds to Isar attributes "where" and "of" with 'for'
wenzelm@57504
  1283
declaration.  INCOMPATIBILITY, also due to potential change of indices
wenzelm@57504
  1284
of schematic variables.
wenzelm@57504
  1285
wenzelm@56303
  1286
* Moved ML_Compiler.exn_trace and other operations on exceptions to
wenzelm@56303
  1287
structure Runtime.  Minor INCOMPATIBILITY.
wenzelm@56303
  1288
wenzelm@56279
  1289
* Discontinued old Toplevel.debug in favour of system option
wenzelm@57452
  1290
"ML_exception_trace", which may be also declared within the context
wenzelm@57452
  1291
via "declare [[ML_exception_trace = true]]".  Minor INCOMPATIBILITY.
wenzelm@56279
  1292
wenzelm@56281
  1293
* Renamed configuration option "ML_trace" to "ML_source_trace". Minor
wenzelm@56281
  1294
INCOMPATIBILITY.
wenzelm@56281
  1295
wenzelm@56281
  1296
* Configuration option "ML_print_depth" controls the pretty-printing
wenzelm@56281
  1297
depth of the ML compiler within the context.  The old print_depth in
wenzelm@56285
  1298
ML is still available as default_print_depth, but rarely used.  Minor
wenzelm@56285
  1299
INCOMPATIBILITY.
wenzelm@56279
  1300
wenzelm@54449
  1301
* Toplevel function "use" refers to raw ML bootstrap environment,
wenzelm@54449
  1302
without Isar context nor antiquotations.  Potential INCOMPATIBILITY.
wenzelm@54449
  1303
Note that 'ML_file' is the canonical command to load ML files into the
wenzelm@54449
  1304
formal context.
wenzelm@54449
  1305
wenzelm@56205
  1306
* Simplified programming interface to define ML antiquotations, see
wenzelm@56205
  1307
structure ML_Antiquotation.  Minor INCOMPATIBILITY.
wenzelm@56069
  1308
wenzelm@56071
  1309
* ML antiquotation @{here} refers to its source position, which is
wenzelm@56071
  1310
occasionally useful for experimentation and diagnostic purposes.
wenzelm@56071
  1311
wenzelm@56135
  1312
* ML antiquotation @{path} produces a Path.T value, similarly to
wenzelm@56135
  1313
Path.explode, but with compile-time check against the file-system and
wenzelm@56135
  1314
some PIDE markup.  Note that unlike theory source, ML does not have a
wenzelm@56135
  1315
well-defined master directory, so an absolute symbolic path
wenzelm@56135
  1316
specification is usually required, e.g. "~~/src/HOL".
wenzelm@56135
  1317
wenzelm@56399
  1318
* ML antiquotation @{print} inlines a function to print an arbitrary
wenzelm@56399
  1319
ML value, which is occasionally useful for diagnostic or demonstration
wenzelm@56399
  1320
purposes.

wenzelm@54683
  1324
wenzelm@57443
  1325
* Proof General with its traditional helper scripts is now an optional
wenzelm@57504
  1326
Isabelle component, e.g. see ProofGeneral-4.2-2 from the Isabelle
wenzelm@57504
  1327
component repository http://isabelle.in.tum.de/components/.  Note that
wenzelm@57504
  1328
the "system" manual provides general explanations about add-on
wenzelm@57504
  1329
components, especially those that are not bundled with the release.
wenzelm@57443
  1330
wenzelm@56439
  1331
* The raw Isabelle process executable has been renamed from
wenzelm@56439
  1332
"isabelle-process" to "isabelle_process", which conforms to common
wenzelm@56439
  1333
shell naming conventions, and allows to define a shell function within
wenzelm@56439
  1334
the Isabelle environment to avoid dynamic path lookup.  Rare
wenzelm@57504
  1335
incompatibility for old tools that do not use the ISABELLE_PROCESS
wenzelm@57504
  1336
settings variable.
wenzelm@56439
  1337
wenzelm@57439
  1338
* Former "isabelle tty" has been superseded by "isabelle console",
wenzelm@57439
  1339
with implicit build like "isabelle jedit", and without the mostly
wenzelm@57439
  1340
obsolete Isar TTY loop.
wenzelm@57439
  1341
wenzelm@57452
  1342
* Simplified "isabelle display" tool.  Settings variables DVI_VIEWER
wenzelm@57452
  1343
and PDF_VIEWER now refer to the actual programs, not shell
wenzelm@57452
  1344
command-lines.  Discontinued option -c: invocation may be asynchronous
wenzelm@57452
  1345
via desktop environment, without any special precautions.  Potential
wenzelm@57452
  1346
INCOMPATIBILITY with ambitious private settings.
wenzelm@57452
  1347
wenzelm@57413
  1348
* Removed obsolete "isabelle unsymbolize".  Note that the usual format
wenzelm@57413
  1349
for email communication is the Unicode rendering of Isabelle symbols,
wenzelm@57413
  1350
as produced by Isabelle/jEdit, for example.
wenzelm@57413
  1351
wenzelm@57452
  1352
* Removed obsolete tool "wwwfind". Similar functionality may be
wenzelm@57452
  1353
integrated into Isabelle/jEdit eventually.
wenzelm@57452
  1354
wenzelm@57452
  1355
* Improved 'display_drafts' concerning desktop integration and
wenzelm@57452
  1356
repeated invocation in PIDE front-end: re-use single file
wenzelm@57452
  1357
$ISABELLE_HOME_USER/tmp/drafts.pdf and corresponding views.
wenzelm@57084
  1358
wenzelm@57452
  1359
* Session ROOT specifications require explicit 'document_files' for
wenzelm@57452
  1360
robust dependencies on LaTeX sources.  Only these explicitly given
wenzelm@57452
  1361
files are copied to the document output directory, before document
wenzelm@57452
  1362
processing is started.
wenzelm@57452
  1363
wenzelm@57504
  1364
* Windows: support for regular TeX installation (e.g. MiKTeX) instead
wenzelm@57504
  1365
of TeX Live from Cygwin.

wenzelm@54639
  1373
wenzelm@54639
  1374
* More robust editing of running commands with internal forks,
wenzelm@54639
  1375
e.g. non-terminating 'by' steps.
wenzelm@54639
  1376
wenzelm@54641
  1377
* More relaxed Sledgehammer panel: avoid repeated application of query
wenzelm@54641
  1378
after edits surrounding the command location.
wenzelm@54641
  1379
wenzelm@54648
  1380
* More status information about commands that are interrupted
wenzelm@54648

accidentally (via physical event or Poly/ML runtime system signal,
wenzelm@54648
  1382
e.g. out-of-memory).

wenzelm@54648
  1392
* Reactivated Isabelle/Scala kill command for external processes on
wenzelm@54648

wenzelm@51293
  1401
*** General ***
wenzelm@51293
  1402
wenzelm@53971
  1403
* Discontinued obsolete 'uses' within theory header.  Note that
wenzelm@53971
  1404
commands like 'ML_file' work without separate declaration of file
wenzelm@53971
  1405
dependencies.  Minor INCOMPATIBILITY.
wenzelm@53971
  1406
wenzelm@53971
  1407
* Discontinued redundant 'use' command, which was superseded by
wenzelm@53971
  1408
'ML_file' in Isabelle2013.  Minor INCOMPATIBILITY.
wenzelm@53971
  1409
wenzelm@53016
  1410
* Simplified subscripts within identifiers, using plain \<^sub>
wenzelm@53016
  1411
instead of the second copy \<^isub> and \<^isup>.  Superscripts are
wenzelm@53016
  1412
only for literal tokens within notation; explicit mixfix annotations
wenzelm@53016
  1413
for consts or fixed variables may be used as fall-back for unusual
wenzelm@53016
  1414
names.  Obsolete \<twosuperior> has been expanded to \<^sup>2 in
wenzelm@53016
  1415
Isabelle/HOL.  INCOMPATIBILITY, use "isabelle update_sub_sup" to
wenzelm@53016
  1416
standardize symbols as a starting point for further manual cleanup.
wenzelm@53016
  1417
The ML reference variable "legacy_isub_isup" may be set as temporary
wenzelm@53016
  1418
workaround, to make the prover accept a subset of the old identifier
wenzelm@53016
  1419
syntax.
wenzelm@53016
  1420
wenzelm@53021
  1421
* Document antiquotations: term style "isub" has been renamed to
wenzelm@53021
  1422
"sub".  Minor INCOMPATIBILITY.
wenzelm@53021
  1423
wenzelm@52487
  1424
* Uniform management of "quick_and_dirty" as system option (see also
wenzelm@52487
  1425
"isabelle options"), configuration option within the context (see also
wenzelm@52487
  1426
Config.get in Isabelle/ML), and attribute in Isabelle/Isar.  Minor
wenzelm@52487
  1427
INCOMPATIBILITY, need to use more official Isabelle means to access
wenzelm@52487
  1428
quick_and_dirty, instead of historical poking into mutable reference.
wenzelm@52059
  1429
wenzelm@52060
  1430
* Renamed command 'print_configs' to 'print_options'.  Minor
wenzelm@52060
  1431
INCOMPATIBILITY.
wenzelm@52060
  1432
wenzelm@52430
  1433
* Proper diagnostic command 'print_state'.  Old 'pr' (with its
wenzelm@52430
  1434
implicit change of some global references) is retained for now as
wenzelm@52430
  1435
control command, e.g. for ProofGeneral 3.7.x.
wenzelm@52430
  1436
wenzelm@52549
  1437
* Discontinued 'print_drafts' command with its old-fashioned PS output
wenzelm@52549
  1438
and Unix command-line print spooling.  Minor INCOMPATIBILITY: use
wenzelm@52549
  1439
'display_drafts' instead and print via the regular document viewer.
wenzelm@52549
  1440
wenzelm@53971
  1441
* Updated and extended "isar-ref" and "implementation" manual,
wenzelm@53971
  1442
eliminated old "ref" manual.

*** Prover IDE -- Isabelle/Scala/jEdit ***
wenzelm@51533
  1446
wenzelm@53971
  1447
* New manual "jedit" for Isabelle/jEdit, see isabelle doc or
wenzelm@53852
  1448
Documentation panel.
wenzelm@53852
  1449
wenzelm@53971
  1450
* Dockable window "Documentation" provides access to Isabelle
wenzelm@53971
  1451
documentation.
wenzelm@52646
  1452
wenzelm@52949
  1453
* Dockable window "Find" provides query operations for formal entities
wenzelm@52949
  1454
(GUI front-end to 'find_theorems' command).
wenzelm@52949
  1455
wenzelm@53050
  1456
* Dockable window "Sledgehammer" manages asynchronous / parallel
wenzelm@53050
  1457
sledgehammer runs over existing document sources, independently of
wenzelm@53050
  1458
normal editing and checking process.
wenzelm@53050
  1459
wenzelm@51533
  1460
* Dockable window "Timing" provides an overview of relevant command
wenzelm@54332
  1461
timing information, depending on option jedit_timing_threshold.  The
wenzelm@54332
  1462
same timing information is shown in the extended tooltip of the
wenzelm@54332
  1463
command keyword, when hovering the mouse over it while the CONTROL or
wenzelm@54332
  1464
COMMAND modifier is pressed.
wenzelm@51533
  1465
wenzelm@53971
  1466
* Improved dockable window "Theories": Continuous checking of proof
wenzelm@53971
  1467
document (visible and required parts) may be controlled explicitly,
wenzelm@53971
  1468
using check box or shortcut "C+e ENTER".  Individual theory nodes may
wenzelm@53971
  1469
be marked explicitly as required and checked in full, using check box
wenzelm@53971
  1470
or shortcut "C+e SPACE".
wenzelm@53971
  1471
wenzelm@54305
  1472
* Improved completion mechanism, which is now managed by the
wenzelm@54305
  1473
Isabelle/jEdit plugin instead of SideKick.  Refined table of Isabelle
wenzelm@54305
  1474
symbol abbreviations (see $ISABELLE_HOME/etc/symbols).
wenzelm@54305
  1475
wenzelm@54319
  1476
* Standard jEdit keyboard shortcut C+b complete-word is remapped to
wenzelm@54319
  1477
isabelle.complete for explicit completion in Isabelle sources.
wenzelm@54319
  1478
INCOMPATIBILITY wrt. jEdit defaults, may have to invent new shortcuts
wenzelm@54319
  1479
to resolve conflict.
wenzelm@54319
  1480
wenzelm@54305
  1481
* Improved support of various "minor modes" for Isabelle NEWS,
wenzelm@54305
  1482
options, session ROOT etc., with completion and SideKick tree view.
wenzelm@54305
  1483
wenzelm@53971
  1484
* Strictly monotonic document update, without premature cancellation of
wenzelm@53971
  1485
running transactions that are still needed: avoid reset/restart of
wenzelm@53971
  1486
such command executions while editing.
wenzelm@53271
  1487
wenzelm@53971
  1488
* Support for asynchronous print functions, as overlay to existing
wenzelm@53971
  1489
document content.
wenzelm@53971
  1490
wenzelm@53971
  1491
* Support for automatic tools in HOL, which try to prove or disprove
wenzelm@53971
  1492
toplevel theorem statements.
wenzelm@53971
  1493
wenzelm@53971
  1494
* Action isabelle.reset-font-size resets main text area font size
wenzelm@54365
  1495
according to Isabelle/Scala plugin option "jedit_font_reset_size" (see
wenzelm@54365
  1496
also "Plugin Options / Isabelle / General").  It can be bound to some
wenzelm@54365
  1497
keyboard shortcut by the user (e.g. C+0 and/or C+NUMPAD0).
wenzelm@53971
  1498
wenzelm@53971
  1499
* File specifications in jEdit (e.g. file browser) may refer to
wenzelm@54351
  1500
$ISABELLE_HOME and $ISABELLE_HOME_USER on all platforms.  Discontinued
wenzelm@54351
  1501
obsolete $ISABELLE_HOME_WINDOWS variable.
wenzelm@53971
  1502
wenzelm@53971
  1503
* Improved support for Linux look-and-feel "GTK+", see also "Utilities
wenzelm@53971
  1504
/ Global Options / Appearance".
wenzelm@53971
  1505
wenzelm@53971

ballarin@54049
  1512
* Commands 'interpretation' and 'sublocale' are now target-sensitive.
ballarin@54049
  1513
In particular, 'interpretation' allows for non-persistent
ballarin@54049
  1514
interpretation within "context ... begin ... end" blocks offering a
ballarin@54049
  1515
light-weight alternative to 'sublocale'.  See "isar-ref" manual for

ballarin@51565
  1518
* Improved locales diagnostic command 'print_dependencies'.
ballarin@51565
  1519
wenzelm@51313
  1520
* Discontinued obsolete 'axioms' command, which has been marked as
wenzelm@51313
  1521
legacy since Isabelle2009-2.  INCOMPATIBILITY, use 'axiomatization'
wenzelm@51313
  1522
instead, while observing its uniform scope for polymorphism.
wenzelm@51313
  1523
wenzelm@51316
  1524
* Discontinued empty name bindings in 'axiomatization'.
wenzelm@51316
  1525
INCOMPATIBILITY.
wenzelm@51316
  1526
wenzelm@53971
  1527
* System option "proofs" has been discontinued.  Instead the global
wenzelm@53971
  1528
state of Proofterm.proofs is persistently compiled into logic images
wenzelm@53971
  1529
as required, notably HOL-Proofs.  Users no longer need to change
wenzelm@53971
  1530
Proofterm.proofs dynamically.  Minor INCOMPATIBILITY.
wenzelm@53971
  1531
wenzelm@53971
  1532
* Syntax translation functions (print_translation etc.) always depend
wenzelm@53971
  1533
on Proof.context.  Discontinued former "(advanced)" option -- this is
wenzelm@53971
  1534
now the default.  Minor INCOMPATIBILITY.
wenzelm@53971
  1535
wenzelm@53971
  1536
* Former global reference trace_unify_fail is now available as
wenzelm@53971
  1537
configuration option "unify_trace_failure" (global context only).
wenzelm@53971
  1538
wenzelm@52463
  1539
* SELECT_GOAL now retains the syntactic context of the overall goal
wenzelm@52463

wenzelm@54032
  1552
* Nested case expressions are now translated in a separate check phase
wenzelm@54032
  1553
rather than during parsing. The data for case combinators is separated
wenzelm@54032
  1554
from the datatype package. The declaration attribute
wenzelm@54032
  1555
"case_translation" can be used to register new case combinators:

* Code generator:
wenzelm@53160
  1560
  - 'code_printing' unifies 'code_const' / 'code_type' / 'code_class' /
wenzelm@53160
  1561
    'code_instance'.
wenzelm@53160
  1562
  - 'code_identifier' declares name hints for arbitrary identifiers in

* Attibute 'code': 'code' now declares concrete and abstract code
wenzelm@54032
  1569
equations uniformly.  Use explicit 'code equation' and 'code abstract'
wenzelm@54032
  1570
to distinguish both when desired.
wenzelm@54032
  1571
wenzelm@54032
  1572
* Discontinued theories Code_Integer and Efficient_Nat by a more
wenzelm@54032
  1573
fine-grain stack of theories Code_Target_Int, Code_Binary_Nat,
wenzelm@54032
  1574
Code_Target_Nat and Code_Target_Numeral.  See the tutorial on code
wenzelm@54032
  1575

wenzelm@54032
  1576
wenzelm@54032
  1577
* Numeric types are mapped by default to target language numerals:
wenzelm@54032
  1578
natural (replaces former code_numeral) and integer (replaces former
wenzelm@54032
  1579
code_int).  Conversions are available as integer_of_natural /
wenzelm@54032
  1580
natural_of_integer / integer_of_nat / nat_of_integer (in HOL) and
wenzelm@54032
  1581
Code_Numeral.integer_of_natural / Code_Numeral.natural_of_integer (in
wenzelm@54032
  1582
ML).  INCOMPATIBILITY.
wenzelm@54032
  1583
wenzelm@54032
  1584
* Function package: For mutually recursive functions f and g, separate
wenzelm@54032
  1585
cases rules f.cases and g.cases are generated instead of unusable
wenzelm@54032
  1586
f_g.cases which exposed internal sum types. Potential INCOMPATIBILITY,
wenzelm@54032
  1587
in the case that the unusable rule was used nevertheless.
wenzelm@54032
  1588
wenzelm@54032
  1589
* Function package: For each function f, new rules f.elims are
wenzelm@54032
  1590
generated, which eliminate equalities of the form "f x = t".
wenzelm@54032
  1591
wenzelm@54032
  1592
* New command 'fun_cases' derives ad-hoc elimination rules for
wenzelm@54032
  1593
function equations as simplified instances of f.elims, analogous to
wenzelm@54032
  1594
inductive_cases.  See ~~/src/HOL/ex/Fundefs.thy for some examples.

* Lifting:
kuncar@54021
  1597
  - parametrized correspondence relations are now supported:
wenzelm@54378
  1598
    + parametricity theorems for the raw term can be specified in
kuncar@54021
  1599
      the command lift_definition, which allow us to generate stronger
kuncar@54021
  1600
      transfer rules
kuncar@54021
  1601
    + setup_lifting generates stronger transfer rules if parametric
kuncar@54021
  1602
      correspondence relation can be generated
kuncar@54021
  1603
    + various new properties of the relator must be specified to support
kuncar@54021
  1604
      parametricity
kuncar@54021
  1605
    + parametricity theorem for the Quotient relation can be specified
kuncar@54021
  1606
  - setup_lifting generates domain rules for the Transfer package
kuncar@54021
  1607
  - stronger reflexivity prover of respectfulness theorems for type
kuncar@54021
  1608
    copies
kuncar@54021
  1609
  - ===> and --> are now local. The symbols can be introduced
kuncar@54021
  1610
    by interpreting the locale lifting_syntax (typically in an
kuncar@54021
  1611
    anonymous context)
wenzelm@54378
  1612
  - Lifting/Transfer relevant parts of Library/Quotient_* are now in
kuncar@54021
  1613
    Main. Potential INCOMPATIBILITY
kuncar@54021
  1614
  - new commands for restoring and deleting Lifting/Transfer context:
kuncar@54021
  1615
    lifting_forget, lifting_update
wenzelm@54378
  1616
  - the command print_quotmaps was renamed to print_quot_maps.

  1617
    INCOMPATIBILITY
kuncar@54021
  1618
kuncar@54021
  1619
* Transfer:
wenzelm@54378
  1620
  - better support for domains in Transfer: replace Domainp T
kuncar@54021
  1621
    by the actual invariant in a transferred goal
kuncar@54021
  1622
  - transfer rules can have as assumptions other transfer rules
kuncar@54021
  1623
  - Experimental support for transferring from the raw level to the
kuncar@54021
  1624
    abstract level: Transfer.transferred attribute
kuncar@54021
  1625
  - Attribute version of the transfer method: untransferred attribute

* Reification and reflection:
wenzelm@53160
  1628
  - Reification is now directly available in HOL-Main in structure
wenzelm@53160
  1629
    "Reification".
wenzelm@53160
  1630
  - Reflection now handles multiple lists with variables also.
wenzelm@53160
  1631
  - The whole reflection stack has been decomposed into conversions.
haftmann@52286
  1632
INCOMPATIBILITY.
haftmann@52286
  1633
haftmann@51489
  1634
* Revised devices for recursive definitions over finite sets:
haftmann@51489
  1635
  - Only one fundamental fold combinator on finite set remains:
haftmann@51489
  1636
    Finite_Set.fold :: ('a => 'b => 'b) => 'b => 'a set => 'b
haftmann@51489
  1637
    This is now identity on infinite sets.
wenzelm@52745
  1638
  - Locales ("mini packages") for fundamental definitions with
haftmann@51489
  1639
    Finite_Set.fold: folding, folding_idem.
haftmann@51489
  1640
  - Locales comm_monoid_set, semilattice_order_set and
haftmann@51489
  1641
    semilattice_neutr_order_set for big operators on sets.
haftmann@51489
  1642
    See theory Big_Operators for canonical examples.
haftmann@51489
  1643
    Note that foundational constants comm_monoid_set.F and
haftmann@51489
  1644
    semilattice_set.F correspond to former combinators fold_image
haftmann@51489
  1645
    and fold1 respectively.  These are now gone.  You may use
haftmann@51490
  1646
    those foundational constants as substitutes, but it is
wenzelm@53983
  1647
    preferable to interpret the above locales accordingly.
haftmann@51489
  1648
  - Dropped class ab_semigroup_idem_mult (special case of lattice,
haftmann@51489
  1649
    no longer needed in connection with Finite_Set.fold etc.)
haftmann@51489
  1650
  - Fact renames:
haftmann@51489
  1651
      card.union_inter ~> card_Un_Int [symmetric]
haftmann@51489
  1652
      card.union_disjoint ~> card_Un_disjoint
haftmann@51489
  1653
INCOMPATIBILITY.
haftmann@51489
  1654
haftmann@51487
  1655
* Locale hierarchy for abstract orderings and (semi)lattices.
haftmann@51487
  1656
wenzelm@53526
  1657
* Complete_Partial_Order.admissible is defined outside the type class
wenzelm@53526
  1658
ccpo, but with mandatory prefix ccpo. Admissibility theorems lose the
wenzelm@53526
  1659
class predicate assumption or sort constraint when possible.
Andreas@53362
  1660
INCOMPATIBILITY.
Andreas@53362
  1661
wenzelm@53160
  1662
* Introduce type class "conditionally_complete_lattice": Like a
wenzelm@53160
  1663
complete lattice but does not assume the existence of the top and
wenzelm@53160
  1664
bottom elements.  Allows to generalize some lemmas about reals and
wenzelm@53160
  1665
extended reals.  Removed SupInf and replaced it by the instantiation
wenzelm@53160
  1666
of conditionally_complete_lattice for real. Renamed lemmas about
wenzelm@53160
  1667
conditionally-complete lattice from Sup_... to cSup_... and from
wenzelm@53160
  1668
Inf_...  to cInf_... to avoid hidding of similar complete lattice
wenzelm@53160
  1669
lemmas.
wenzelm@53160
  1670
wenzelm@53160
  1671
* Introduce type class linear_continuum as combination of
wenzelm@53160
  1672
conditionally-complete lattices and inner dense linorders which have
wenzelm@53160
  1673
more than one element.  INCOMPATIBILITY.
wenzelm@53160
  1674
wenzelm@53983
  1675
* Introduced type classes order_top and order_bot. The old classes top
wenzelm@53983
  1676
and bot only contain the syntax without assumptions.  INCOMPATIBILITY:
wenzelm@53983
  1677
Rename bot -> order_bot, top -> order_top
lammich@53683
  1678
wenzelm@53160
  1679
* Introduce type classes "no_top" and "no_bot" for orderings without
wenzelm@53160
  1680
top and bottom elements.
hoelzl@51732
  1681
hoelzl@51732
  1682
* Split dense_linorder into inner_dense_order and no_top, no_bot.
hoelzl@51732
  1683
hoelzl@51732
  1684
* Complex_Main: Unify and move various concepts from
wenzelm@53160
  1685
HOL-Multivariate_Analysis to HOL-Complex_Main.
hoelzl@51732
  1686
wenzelm@53983
  1687
 - Introduce type class (lin)order_topology and
wenzelm@53983
  1688
   linear_continuum_topology.  Allows to generalize theorems about
wenzelm@53983
  1689
   limits and order.  Instances are reals and extended reals.
hoelzl@51732
  1690
hoelzl@51732
  1691
 - continuous and continuos_on from Multivariate_Analysis:
wenzelm@53983
  1692
   "continuous" is the continuity of a function at a filter.  "isCont"
wenzelm@53983
  1693
   is now an abbrevitation: "isCont x f == continuous (at _) f".
wenzelm@53983
  1694
wenzelm@53983
  1695
   Generalized continuity lemmas from isCont to continuous on an
wenzelm@53983
  1696
   arbitrary filter.
wenzelm@53983
  1697
wenzelm@53983
  1698
 - compact from Multivariate_Analysis. Use Bolzano's lemma to prove
wenzelm@53983
  1699
   compactness of closed intervals on reals. Continuous functions
wenzelm@53983
  1700
   attain infimum and supremum on compact sets. The inverse of a
wenzelm@53983
  1701
   continuous function is continuous, when the function is continuous
wenzelm@53983
  1702
   on a compact set.
hoelzl@51732
  1703
hoelzl@51732
  1704
 - connected from Multivariate_Analysis. Use it to prove the
hoelzl@51775
  1705
   intermediate value theorem. Show connectedness of intervals on
hoelzl@51775
  1706
   linear_continuum_topology).
hoelzl@51732
  1707
hoelzl@51732
  1708
 - first_countable_topology from Multivariate_Analysis. Is used to
wenzelm@53983
  1709
   show equivalence of properties on the neighbourhood filter of x and
wenzelm@53983
  1710
   on all sequences converging to x.
wenzelm@53983
  1711
wenzelm@53983
  1712
 - FDERIV: Definition of has_derivative moved to Deriv.thy. Moved
wenzelm@53983
  1713
   theorems from Library/FDERIV.thy to Deriv.thy and base the
wenzelm@53983
  1714
   definition of DERIV on FDERIV. Add variants of DERIV and FDERIV
wenzelm@53983
  1715
   which are restricted to sets, i.e. to represent derivatives from
wenzelm@53983
  1716
   left or right.
hoelzl@51732
  1717
hoelzl@51732
  1718
 - Removed the within-filter. It is replaced by the principal filter:
hoelzl@51732
  1719
hoelzl@51732
  1720
     F within X = inf F (principal X)
hoelzl@51732
  1721
hoelzl@51732
  1722
 - Introduce "at x within U" as a single constant, "at x" is now an
hoelzl@51732
  1723
   abbreviation for "at x within UNIV"
hoelzl@51732
  1724
wenzelm@53983
  1725
 - Introduce named theorem collections tendsto_intros,
wenzelm@53983
  1726
   continuous_intros, continuous_on_intros and FDERIV_intros. Theorems
wenzelm@53983
  1727
   in tendsto_intros (or FDERIV_intros) are also available as
wenzelm@53983
  1728
   tendsto_eq_intros (or FDERIV_eq_intros) where the right-hand side
wenzelm@53983
  1729
   is replaced by a congruence rule. This allows to apply them as
wenzelm@53983
  1730
   intro rules and then proving equivalence by the simplifier.
hoelzl@51732
  1731
hoelzl@51732
  1732
 - Restructured theories in HOL-Complex_Main:
hoelzl@51732
  1733
hoelzl@51732
  1734
   + Moved RealDef and RComplete into Real
hoelzl@51732
  1735
hoelzl@51732
  1736
   + Introduced Topological_Spaces and moved theorems about
hoelzl@51732
  1737
     topological spaces, filters, limits and continuity to it
hoelzl@51732
  1738
hoelzl@51732
  1739
   + Renamed RealVector to Real_Vector_Spaces
hoelzl@51732
  1740
wenzelm@53983
  1741
   + Split Lim, SEQ, Series into Topological_Spaces,
wenzelm@53983
  1742
     Real_Vector_Spaces, and Limits
hoelzl@51732
  1743
hoelzl@51732
  1744
   + Moved Ln and Log to Transcendental
hoelzl@51732
  1745
hoelzl@51732
  1746
   + Moved theorems about continuity from Deriv to Topological_Spaces
hoelzl@51732
  1747
hoelzl@51732
  1748
 - Remove various auxiliary lemmas.

blanchet@55889
  1761
  - Better support for "isar_proofs".
blanchet@55889
  1762
  - MaSh has been fined-tuned and now runs as a local server.
blanchet@51137
  1763
wenzelm@54032
  1764
* Improved support for ad hoc overloading of constants (see also

wenzelm@54032
  1766
wenzelm@54032
  1767
* Library/Polynomial.thy:
wenzelm@54032
  1768
  - Use lifting for primitive definitions.
wenzelm@54032
  1769
  - Explicit conversions from and to lists of coefficients, used for
wenzelm@54032
  1770
    generated code.
wenzelm@54032
  1771
  - Replaced recursion operator poly_rec by fold_coeffs.
wenzelm@54032
  1772
  - Prefer pre-existing gcd operation for gcd.
wenzelm@54032
  1773
  - Fact renames:

IMCOMPATIBILITY.
wenzelm@54032
  1778
wenzelm@54032
  1779
* New Library/Simps_Case_Conv.thy: Provides commands simps_of_case and
wenzelm@54032
  1780
case_of_simps to convert function definitions between a list of
wenzelm@54032
  1781
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
  1783
wenzelm@54032

  1785
sets defined by Lifting/Transfer.
wenzelm@54032
  1786
wenzelm@54032

* Discontinued theory src/HOL/Library/Eval_Witness.  INCOMPATIBILITY.
wenzelm@54032
  1788
wenzelm@54032

  1800
* HOL-Algebra: Discontinued theories ~~/src/HOL/Algebra/abstract and
wenzelm@53983
  1801
~~/src/HOL/Algebra/poly.  Existing theories should be based on
wenzelm@53983

* HOL-BNF:
wenzelm@54032
  1806
  - Various improvements to BNF-based (co)datatype package, including

  1828
* Spec_Check is a Quickcheck tool for Isabelle/ML.  The ML function
wenzelm@53971
  1829
"check_property" allows to check specifications of the form "ALL x y
wenzelm@53971
  1830
z. prop x y z".  See also ~~/src/Tools/Spec_Check/ with its
wenzelm@53971
  1831
Examples.thy in particular.
wenzelm@53971
  1832
wenzelm@53709
  1833
* Improved printing of exception trace in Poly/ML 5.5.1, with regular
wenzelm@53709
  1834
tracing output in the command transaction context instead of physical
wenzelm@53709
  1835

wenzelm@53971
  1838
* ML type "theory" is now immutable, without any special treatment of
wenzelm@53971
  1839
drafts or linear updates (which could lead to "stale theory" errors in
wenzelm@53971
  1840
the past).  Discontinued obsolete operations like Theory.copy,
wenzelm@53971
  1841
Theory.checkpoint, and the auxiliary type theory_ref.  Minor
wenzelm@53971
  1842
INCOMPATIBILITY.
wenzelm@53164
  1843
wenzelm@51551
  1844
* More uniform naming of goal functions for skipped proofs:
wenzelm@51551
  1845
wenzelm@51551
  1846
    Skip_Proof.prove  ~>  Goal.prove_sorry
wenzelm@51551

    Skip_Proof.prove_global  ~>  Goal.prove_sorry_global
wenzelm@51551
  1848
wenzelm@53971
  1849
Minor INCOMPATIBILITY.
wenzelm@51703
  1850
wenzelm@51717
  1851
* Simplifier tactics and tools use proper Proof.context instead of
wenzelm@51717
  1852
historic type simpset.  Old-style declarations like addsimps,
wenzelm@51717
  1853
addsimprocs etc. operate directly on Proof.context.  Raw type simpset
wenzelm@51717
  1854
retains its use as snapshot of the main Simplifier context, using
wenzelm@51717
  1855
simpset_of and put_simpset on Proof.context.  INCOMPATIBILITY -- port
wenzelm@51717
  1856
old tools by making them depend on (ctxt : Proof.context) instead of
wenzelm@51717
  1857
(ss : simpset), then turn (simpset_of ctxt) into ctxt.
wenzelm@51717
  1858
wenzelm@53971
  1859
* Modifiers for classical wrappers (e.g. addWrapper, delWrapper)
wenzelm@53971
  1860
operate on Proof.context instead of claset, for uniformity with addIs,
wenzelm@53971
  1861
addEs, addDs etc. Note that claset_of and put_claset allow to manage
wenzelm@53971
  1862
clasets separately from the context.
wenzelm@53971
  1863
wenzelm@51717
  1864
* Discontinued obsolete ML antiquotations @{claset} and @{simpset}.
wenzelm@51717
  1865
INCOMPATIBILITY, use @{context} instead.
wenzelm@51717
  1866
wenzelm@53971
  1867
* Antiquotation @{theory_context A} is similar to @{theory A}, but
wenzelm@53971

wenzelm@52550
  1881
wenzelm@52746

* Discontinued ISABELLE_DOC_FORMAT settings variable and historic
wenzelm@52746
  1883
document formats: dvi.gz, ps, ps.gz -- the default document format is
wenzelm@52746
  1884
always pdf.
wenzelm@52743
  1885
wenzelm@52053
  1886
* Isabelle settings variable ISABELLE_BUILD_JAVA_OPTIONS allows to

wenzelm@52053
  1888
wenzelm@52116

wenzelm@52116
  1891
wenzelm@52439
  1892
* Improved "isabelle keywords" tool (for old-style ProofGeneral
wenzelm@52439
  1893
keyword tables): use Isabelle/Scala operations, which inspect outer
wenzelm@52439
  1894
syntax without requiring to build sessions first.
wenzelm@52439
  1895
wenzelm@53971
  1896
* Sessions may be organized via 'chapter' specifications in the ROOT
wenzelm@53971
  1897
file, which determines a two-level hierarchy of browser info.  The old
wenzelm@53971
  1898
tree-like organization via implicit sub-session relation (with its
wenzelm@53971
  1899
tendency towards erratic fluctuation of URLs) has been discontinued.

wenzelm@50126
  1910
* Theorem status about oracles and unfinished/failed future proofs is
wenzelm@50126
  1911
no longer printed by default, since it is incompatible with
wenzelm@50126
  1912
incremental / parallel checking of the persistent document model.  ML
wenzelm@50126
  1913
function Thm.peek_status may be used to inspect a snapshot of the
wenzelm@50126
  1914
ongoing evaluation process.  Note that in batch mode --- notably
wenzelm@50126
  1915
isabelle build --- the system ensures that future proofs of all
wenzelm@50126
  1916
accessible theorems in the theory context are finished (as before).
wenzelm@50126
  1917
wenzelm@49699
  1918
* Configuration option show_markup controls direct inlining of markup
wenzelm@49699
  1919
into the printed representation of formal entities --- notably type
wenzelm@49699
  1920
and sort constraints.  This enables Prover IDE users to retrieve that
wenzelm@49699
  1921
information via tooltips in the output window, for example.
wenzelm@49699
  1922
wenzelm@48890
  1923
* Command 'ML_file' evaluates ML text from a file directly within the
wenzelm@48890
  1924
theory, without any predeclaration via 'uses' in the theory header.
wenzelm@48890
  1925
wenzelm@49243
  1926
* Old command 'use' command and corresponding keyword 'uses' in the
wenzelm@49243
  1927
theory header are legacy features and will be discontinued soon.
wenzelm@49243
  1928
Tools that load their additional source files may imitate the
wenzelm@49243
  1929
'ML_file' implementation, such that the system can take care of
wenzelm@49243
  1930
dependencies properly.
wenzelm@49243
  1931
wenzelm@47967
  1932
* Discontinued obsolete method fastsimp / tactic fast_simp_tac, which
wenzelm@47967
  1933
is called fastforce / fast_force_tac already since Isabelle2011-1.
wenzelm@47967
  1934
wenzelm@50110
  1935
* Updated and extended "isar-ref" and "implementation" manual, reduced
wenzelm@50110
  1936
remaining material in old "ref" manual.
wenzelm@48120
  1937
wenzelm@51050
  1938
* Improved support for auxiliary contexts that indicate block structure
wenzelm@51050
  1939
for specifications.  Nesting of "context fixes ... context assumes ..."
wenzelm@49841
  1940
and "class ... context ...".
wenzelm@49841
  1941
wenzelm@50772
  1942
* Attribute "consumes" allows a negative value as well, which is
wenzelm@50778
  1943
interpreted relatively to the total number of premises of the rule in
wenzelm@50772
  1944
the target context.  This form of declaration is stable when exported
wenzelm@50772
  1945
from a nested 'context' with additional assumptions.  It is the
wenzelm@50772
  1946
preferred form for definitional packages, notably cases/rules produced
wenzelm@50772
  1947
in HOL/inductive and HOL/function.
wenzelm@50772
  1948
wenzelm@49869
  1949
* More informative error messages for Isar proof commands involving
wenzelm@49869
  1950
lazy enumerations (method applications etc.).
wenzelm@49869
  1951
wenzelm@50213
  1952
* Refined 'help' command to retrieve outer syntax commands according
wenzelm@50213
  1953
to name patterns (with clickable results).

*** Prover IDE -- Isabelle/Scala/jEdit ***
wenzelm@49968
  1957
wenzelm@49968
  1958
* Parallel terminal proofs ('by') are enabled by default, likewise
wenzelm@49968
  1959
proofs that are built into packages like 'datatype', 'function'.  This
wenzelm@49968
  1960
allows to "run ahead" checking the theory specifications on the
wenzelm@49968
  1961
surface, while the prover is still crunching on internal
wenzelm@49968
  1962
justifications.  Unfinished / cancelled proofs are restarted as
wenzelm@49968
  1963
required to complete full proof checking eventually.
wenzelm@49968
  1964
wenzelm@49968
  1965
* Improved output panel with tooltips, hyperlinks etc. based on the
wenzelm@49968
  1966
same Rich_Text_Area as regular Isabelle/jEdit buffers.  Activation of
wenzelm@49968
  1967
tooltips leads to some window that supports the same recursively,
wenzelm@49968
  1968
which can lead to stacks of tooltips as the semantic document content
wenzelm@49968
  1969
is explored.  ESCAPE closes the whole stack, individual windows may be
wenzelm@49968
  1970
closed separately, or detached to become independent jEdit dockables.
wenzelm@49968
  1971
wenzelm@50717
  1972
* Improved support for commands that produce graph output: the text
wenzelm@50717
  1973
message contains a clickable area to open a new instance of the graph
wenzelm@50717
  1974
browser on demand.
wenzelm@50717
  1975
wenzelm@49968
  1976
* More robust incremental parsing of outer syntax (partial comments,
wenzelm@49968
  1977
malformed symbols).  Changing the balance of open/close quotes and
wenzelm@49968
  1978
comment delimiters works more conveniently with unfinished situations
wenzelm@49968
  1979
that frequently occur in user interaction.
wenzelm@49968
  1980
wenzelm@49968
  1981
* More efficient painting and improved reactivity when editing large
wenzelm@49968
  1982
files.  More scalable management of formal document content.
wenzelm@49968
  1983
wenzelm@50505
  1984
* Smarter handling of tracing messages: prover process pauses after
wenzelm@50505
  1985
certain number of messages per command transaction, with some user
wenzelm@50505
  1986
dialog to stop or continue.  This avoids swamping the front-end with
wenzelm@50119
  1987
potentially infinite message streams.
wenzelm@49968
  1988
wenzelm@49968
  1989
* More plugin options and preferences, based on Isabelle/Scala.  The
wenzelm@49968
  1990
jEdit plugin option panel provides access to some Isabelle/Scala
wenzelm@49968
  1991
options, including tuning parameters for editor reactivity and color
wenzelm@49968
  1992
schemes.
wenzelm@49968
  1993
wenzelm@50184
  1994
* Dockable window "Symbols" provides some editing support for Isabelle
wenzelm@50184
  1995
symbols.
wenzelm@50184
  1996
wenzelm@51082
  1997
* Dockable window "Monitor" shows ML runtime statistics.  Note that
wenzelm@51082
  1998
continuous display of the chart slows down the system.
wenzelm@50701
  1999
wenzelm@50183
  2000
* Improved editing support for control styles: subscript, superscript,
wenzelm@50183
  2001
bold, reset of style -- operating on single symbols or text
wenzelm@50198
  2002
selections.  Cf. keyboard shortcuts C+e DOWN/UP/RIGHT/LEFT.
wenzelm@50198
  2003
wenzelm@50198
  2004
* Actions isabelle.increase-font-size and isabelle.decrease-font-size
wenzelm@50198
  2005
adjust the main text area font size, and its derivatives for output,
wenzelm@50836
  2006
tooltips etc.  Cf. keyboard shortcuts C-PLUS and C-MINUS, which often
wenzelm@50836
  2007
need to be adapted to local keyboard layouts.
wenzelm@50183
  2008
wenzelm@50730
  2009
* More reactive completion popup by default: use \t (TAB) instead of
wenzelm@50730
  2010
\n (NEWLINE) to minimize intrusion into regular flow of editing.  See
wenzelm@50730
  2011
also "Plugin Options / SideKick / General / Code Completion Options".
wenzelm@50730
  2012
wenzelm@50406
  2013
* Implicit check and build dialog of the specified logic session
wenzelm@50406
  2014
image.  For example, HOL, HOLCF, HOL-Nominal can be produced on
wenzelm@50406
  2015
demand, without bundling big platform-dependent heap images in the
wenzelm@50406
  2016
Isabelle distribution.
wenzelm@50406
  2017
wenzelm@49968
  2018
* Uniform Java 7 platform on Linux, Mac OS X, Windows: recent updates
wenzelm@49968
  2019
from Oracle provide better multi-platform experience.  This version is
wenzelm@49968
  2020
now bundled exclusively with Isabelle.

  2026
Haskell Prelude to a small set of fundamental operations.
haftmann@48431
  2027
wenzelm@50646
  2028
* Command 'export_code': relative file names are interpreted
wenzelm@50646
  2029
relatively to master directory of current theory rather than the
wenzelm@50646
  2030
rather arbitrary current working directory.  INCOMPATIBILITY.

* Discontinued obsolete attribute "COMP".  Potential INCOMPATIBILITY,
wenzelm@48205
  2033
use regular rule composition via "OF" / "THEN", or explicit proof
wenzelm@48205
  2034
structure instead.  Note that Isabelle/ML provides a variety of
wenzelm@48205
  2035
operators like COMP, INCR_COMP, COMP_INCR, which need to be applied
wenzelm@48205
  2036
with some care where this is really required.
wenzelm@48205
  2037
wenzelm@48792
  2038
* Command 'typ' supports an additional variant with explicit sort
wenzelm@48792
  2039
constraint, to infer and check the most general type conforming to a
wenzelm@51063
  2040
given sort.  Example (in HOL):
wenzelm@48792
  2041
wenzelm@48792

  typ "_ * _ * bool * unit" :: finite
wenzelm@48792

wenzelm@50646
  2119
wenzelm@50646
  2120
* Generalized the definition of limits:
wenzelm@50646
  2121
wenzelm@50646
  2122
  - Introduced the predicate filterlim (LIM x F. f x :> G) which
wenzelm@50646
  2123
    expresses that when the input values x converge to F then the
wenzelm@50646
  2124
    output f x converges to G.
wenzelm@50646
  2125
wenzelm@50646
  2126
  - Added filters for convergence to positive (at_top) and negative
wenzelm@50646
  2127
    infinity (at_bot).
wenzelm@50646
  2128
wenzelm@50646
  2129
  - Moved infinity in the norm (at_infinity) from
wenzelm@50646
  2130
    Multivariate_Analysis to Complex_Main.
wenzelm@50646
  2131
wenzelm@50646
  2132
  - Removed real_tendsto_inf, it is superseded by "LIM x F. f x :>
wenzelm@50646
  2133
    at_top".
wenzelm@50646

wenzelm@50646
  2135
INCOMPATIBILITY.
wenzelm@50646
  2136
wenzelm@50646
  2137
* Theory "Library/Option_ord" provides instantiation of option type to
wenzelm@50646
  2138
lattice type classes.
wenzelm@50646
  2139
wenzelm@50646
  2140
* Theory "Library/Multiset": renamed
wenzelm@50646
  2141

  2142
    constant fold_mset ~> Multiset.fold
wenzelm@50646

INCOMPATIBILITY.
wenzelm@50646
  2146
wenzelm@50646
  2147
* Renamed theory Library/List_Prefix to Library/Sublist, with related
wenzelm@50646
  2148
changes as follows.
wenzelm@50646
  2149
wenzelm@50646
  2150
  - Renamed constants (and related lemmas)
Christian@49145
  2151
Christian@49145
  2152
      prefix ~> prefixeq
Christian@49145
  2153
      strict_prefix ~> prefix
Christian@49145
  2154
wenzelm@50646
  2155
  - Replaced constant "postfix" by "suffixeq" with swapped argument
wenzelm@50646
  2156
    order (i.e., "postfix xs ys" is now "suffixeq ys xs") and dropped
wenzelm@50646
  2157
    old infix syntax "xs >>= ys"; use "suffixeq ys xs" instead.
wenzelm@50646
  2158
    Renamed lemmas accordingly.
wenzelm@50646
  2159
wenzelm@50646
  2160
  - Added constant "list_hembeq" for homeomorphic embedding on
wenzelm@50646
  2161
    lists. Added abbreviation "sublisteq" for special case
wenzelm@50646
  2162
    "list_hembeq (op =)".
wenzelm@50646
  2163
wenzelm@50646
  2164
  - Theory Library/Sublist no longer provides "order" and "bot" type
wenzelm@50646
  2165
    class instances for the prefix order (merely corresponding locale
wenzelm@50646
  2166
    interpretations). The type class instances are now in theory
wenzelm@50646
  2167
    Library/Prefix_Order.
wenzelm@50646
  2168
wenzelm@50646
  2169
  - The sublist relation of theory Library/Sublist_Order is now based
wenzelm@50646
  2170
    on "Sublist.sublisteq".  Renamed lemmas accordingly:
Christian@50516
  2171
Christian@50516

wenzelm@50646
  2190
wenzelm@50646
  2191
* New theory Library/Countable_Set.
wenzelm@50646
  2192
wenzelm@50646
  2193
* Theory Library/Debug and Library/Parallel provide debugging and
wenzelm@50646
  2194
parallel execution for code generated towards Isabelle/ML.
wenzelm@50646
  2195
wenzelm@50646
  2196
* Theory Library/FuncSet: Extended support for Pi and extensional and
wenzelm@50646
  2197
introduce the extensional dependent function space "PiE". Replaced
wenzelm@50646
  2198
extensional_funcset by an abbreviation, and renamed lemmas from
wenzelm@50646
  2199
extensional_funcset to PiE as follows:

wenzelm@50646
  2212
INCOMPATIBILITY.
wenzelm@50646
  2213
wenzelm@50646
  2214
* Theory Library/FinFun: theory of almost everywhere constant
wenzelm@50646
  2215
functions (supersedes the AFP entry "Code Generation for Functions as
wenzelm@50646
  2216
Data").
wenzelm@50646
  2217
wenzelm@50646
  2218
* Theory Library/Phantom: generic phantom type to make a type
wenzelm@50646
  2219
parameter appear in a constant's type.  This alternative to adding
wenzelm@50646
  2220
TYPE('a) as another parameter avoids unnecessary closures in generated
wenzelm@50646
  2221
code.
wenzelm@50646
  2222
wenzelm@50646
  2223
* Theory Library/RBT_Impl: efficient construction of red-black trees
wenzelm@50646
  2224
from sorted associative lists. Merging two trees with rbt_union may
wenzelm@50646
  2225
return a structurally different tree than before.  Potential
wenzelm@50646
  2226
INCOMPATIBILITY.
wenzelm@50646
  2227
wenzelm@50646

wenzelm@50646
  2233
wenzelm@50646
  2234
  "basis :: 'a::euclidean_space => nat => real"
wenzelm@50646
  2235
  "\<Chi>\<Chi> :: (nat => real) => 'a::euclidean_space"
wenzelm@50646
  2236
wenzelm@50646
  2237
on euclidean spaces by using the inner product "_ \<bullet> _" with
wenzelm@50646
  2238
vectors from the Basis set: "\<Chi>\<Chi> i. f i" is superseded by
wenzelm@50646
  2239
"SUM i : Basis. f i * r i".
wenzelm@50646
  2240
wenzelm@50646
  2241
  With this change the following constants are also changed or removed:
wenzelm@50646
  2242
wenzelm@50646
  2243
    DIM('a) :: nat  ~>  card (Basis :: 'a set)   (is an abbreviation)
wenzelm@50646
  2244
    a $$ i  ~>  inner a i  (where i : Basis)
wenzelm@50646
  2245
    cart_base i  removed
wenzelm@50646
  2246
    \<pi>, \<pi>'  removed
hoelzl@50526

hoelzl@50526
  2248
  Theorems about these constants where removed.
hoelzl@50526
  2249
hoelzl@50526

  2265
* HOL/Probability:
wenzelm@50646
  2266
wenzelm@50646
  2267
  - Added simproc "measurable" to automatically prove measurability.
wenzelm@50646
  2268
wenzelm@50646
  2269
  - Added induction rules for sigma sets with disjoint union
wenzelm@50646
  2270
    (sigma_sets_induct_disjoint) and for Borel-measurable functions
wenzelm@50646
  2271
    (borel_measurable_induct).
wenzelm@50646
  2272
wenzelm@50646
  2273
  - Added the Daniell-Kolmogorov theorem (the existence the limit of a
wenzelm@50646
  2274
    projective family).
wenzelm@50646
  2275
wenzelm@50646
  2276
* HOL/Cardinals: Theories of ordinals and cardinals (supersedes the
wenzelm@50646
  2277
AFP entry "Ordinals_and_Cardinals").
wenzelm@50646
  2278
wenzelm@50646
  2279
* HOL/BNF: New (co)datatype package based on bounded natural functors
wenzelm@50646
  2280
with support for mixed, nested recursion and interesting non-free
wenzelm@50646
  2281
datatypes.
blanchet@48094
  2282
wenzelm@50991
  2283
* HOL/Finite_Set and Relation: added new set and relation operations
kuncar@50878
  2284
expressed by Finite_Set.fold.
kuncar@50878
  2285
kuncar@50878
  2286
* New theory HOL/Library/RBT_Set: implementation of sets by red-black
kuncar@50878
  2287
trees for the code generator.
kuncar@50878
  2288
kuncar@50878
  2289
* HOL/Library/RBT and HOL/Library/Mapping have been converted to
kuncar@50878
  2290
Lifting/Transfer.
kuncar@50878
  2291
possible INCOMPATIBILITY.
kuncar@50878

*** Document preparation ***
wenzelm@48206
  2298
wenzelm@50646
  2299
* Dropped legacy antiquotations "term_style" and "thm_style", since
wenzelm@50646
  2300
styles may be given as arguments to "term" and "thm" already.
wenzelm@50646
  2301
Discontinued legacy styles "prem1" .. "prem19".
wenzelm@50646
  2302
wenzelm@50646
  2303
* Default LaTeX rendering for \<euro> is now based on eurosym package,
wenzelm@50646
  2304
instead of slightly exotic babel/greek.
wenzelm@48206
  2305
wenzelm@48616
  2306
* Document variant NAME may use different LaTeX entry point
wenzelm@48616
  2307
document/root_NAME.tex if that file exists, instead of the common
wenzelm@48616
  2308
document/root.tex.
wenzelm@48616
  2309
wenzelm@48657
  2310
* Simplified custom document/build script, instead of old-style
wenzelm@48657
  2311
document/IsaMakefile.  Minor INCOMPATIBILITY.
wenzelm@48657

wenzelm@48992
  2314
*** ML ***
wenzelm@48992
  2315
wenzelm@50646
  2316
* The default limit for maximum number of worker threads is now 8,
wenzelm@50646
  2317
instead of 4, in correspondence to capabilities of contemporary
wenzelm@50646
  2318
hardware and Poly/ML runtime system.
wenzelm@50646
  2319
wenzelm@49869
  2320
* Type Seq.results and related operations support embedded error
wenzelm@49869
  2321
messages within lazy enumerations, and thus allow to provide
wenzelm@49869
  2322
informative errors in the absence of any usable results.
wenzelm@49869
  2323
wenzelm@48992
  2324
* Renamed Position.str_of to Position.here to emphasize that this is a
wenzelm@48992
  2325
formal device to inline positions into message text, but not
wenzelm@48992
  2326
necessarily printing visible text.

*** System ***
wenzelm@48206
  2330
wenzelm@48585
  2331
* Advanced support for Isabelle sessions and build management, see
wenzelm@48585
  2332
"system" manual for the chapter of that name, especially the "isabelle
wenzelm@51056
  2333
build" tool and its examples.  The "isabelle mkroot" tool prepares
wenzelm@51056
  2334
session root directories for use with "isabelle build", similar to
wenzelm@51056
  2335
former "isabelle mkdir" for "isabelle usedir".  Note that this affects
wenzelm@51056
  2336
document preparation as well.  INCOMPATIBILITY, isabelle usedir /
wenzelm@48736
  2337
mkdir / make are rendered obsolete.
wenzelm@48736
  2338
wenzelm@51056
  2339
* Discontinued obsolete Isabelle/build script, it is superseded by the
wenzelm@51056
  2340
regular isabelle build tool.  For example:
wenzelm@51056
  2341
wenzelm@51056
  2342
  isabelle build -s -b HOL
wenzelm@51056
  2343
wenzelm@48736
  2344
* Discontinued obsolete "isabelle makeall".
wenzelm@48585
  2345
wenzelm@48722
  2346
* Discontinued obsolete IsaMakefile and ROOT.ML files from the
wenzelm@48722
  2347
Isabelle distribution, except for rudimentary src/HOL/IsaMakefile that
wenzelm@48722
  2348
provides some traditional targets that invoke "isabelle build".  Note
wenzelm@48722
  2349
that this is inefficient!  Applications of Isabelle/HOL involving
wenzelm@48722
  2350
"isabelle make" should be upgraded to use "isabelle build" directly.
wenzelm@48722
  2351
wenzelm@48693
  2352
* The "isabelle options" tool prints Isabelle system options, as
wenzelm@48693
  2353
required for "isabelle build", for example.
wenzelm@48693
  2354
wenzelm@50646
  2355
* The "isabelle logo" tool produces EPS and PDF format simultaneously.
wenzelm@50646
  2356
Minor INCOMPATIBILITY in command-line options.
wenzelm@50646
  2357
wenzelm@50646
  2358
* The "isabelle install" tool has now a simpler command-line.  Minor
wenzelm@50646
  2359
INCOMPATIBILITY.
wenzelm@50646
  2360
wenzelm@48844
  2361
* The "isabelle components" tool helps to resolve add-on components
wenzelm@48844
  2362
that are not bundled, or referenced from a bare-bones repository
wenzelm@48844
  2363
version of Isabelle.
wenzelm@48844
  2364
wenzelm@50646
  2365
* Settings variable ISABELLE_PLATFORM_FAMILY refers to the general
wenzelm@50646
  2366
platform family: "linux", "macos", "windows".
wenzelm@50646
  2367
wenzelm@50646
  2368
* The ML system is configured as regular component, and no longer
wenzelm@50646
  2369
picked up from some surrounding directory.  Potential INCOMPATIBILITY
wenzelm@50646
  2370
for home-made settings.
wenzelm@50132
  2371
wenzelm@50701
  2372
* Improved ML runtime statistics (heap, threads, future tasks etc.).
wenzelm@50701
  2373
wenzelm@48206
  2374
* Discontinued support for Poly/ML 5.2.1, which was the last version
wenzelm@48206
  2375
without exception positions and advanced ML compiler/toplevel
wenzelm@48206
  2376
configuration.

PROOFGENERAL_HOME based on accidental file-system layout.  Minor
wenzelm@48574
  2380
INCOMPATIBILITY: provide PROOFGENERAL_HOME and PROOFGENERAL_OPTIONS

*** General ***
wenzelm@45593
  2390
wenzelm@45614
  2391
* Prover IDE (PIDE) improvements:
wenzelm@45614
  2392
wenzelm@47585
  2393
  - more robust Sledgehammer integration (as before the sledgehammer
wenzelm@47806
  2394
    command-line needs to be typed into the source buffer)
wenzelm@45614
  2395
  - markup for bound variables
wenzelm@47806
  2396
  - markup for types of term variables (displayed as tooltips)
wenzelm@46956
  2397
  - support for user-defined Isar commands within the running session
wenzelm@47158
  2398
  - improved support for Unicode outside original 16bit range
wenzelm@47158
  2399
    e.g. glyph for \<A> (thanks to jEdit 4.5.1)
wenzelm@45614
  2400
wenzelm@47806
  2401
* Forward declaration of outer syntax keywords within the theory
wenzelm@47806
  2402
header -- minor INCOMPATIBILITY for user-defined commands.  Allow new
wenzelm@47806
  2403
commands to be used in the same theory where defined.
wenzelm@46485
  2404
wenzelm@47482
  2405
* Auxiliary contexts indicate block structure for specifications with
wenzelm@47482
  2406
additional parameters and assumptions.  Such unnamed contexts may be
wenzelm@47482
  2407
nested within other targets, like 'theory', 'locale', 'class',
wenzelm@47482
  2408
'instantiation' etc.  Results from the local context are generalized
wenzelm@47482
  2409
accordingly and applied to the enclosing target context.  Example:
wenzelm@47482
  2410
wenzelm@47482
  2411
  context
wenzelm@47482
  2412
    fixes x y z :: 'a
wenzelm@47482
  2413
    assumes xy: "x = y" and yz: "y = z"
wenzelm@47482
  2414
  begin
wenzelm@47482
  2415
wenzelm@47482
  2416
  lemma my_trans: "x = z" using xy yz by simp
wenzelm@47482
  2417
wenzelm@47482
  2418
  end
wenzelm@47482
  2419
wenzelm@47482
  2420
  thm my_trans
wenzelm@47482
  2421
wenzelm@47482
  2422
The most basic application is to factor-out context elements of
wenzelm@47482
  2423
several fixes/assumes/shows theorem statements, e.g. see
wenzelm@47482
  2424
~~/src/HOL/Isar_Examples/Group_Context.thy
wenzelm@47482
  2425
wenzelm@47482
  2426
Any other local theory specification element works within the "context
wenzelm@47482
  2427
... begin ... end" block as well.
wenzelm@47482
  2428
wenzelm@47484
  2429
* Bundled declarations associate attributed fact expressions with a
wenzelm@47484
  2430
given name in the context.  These may be later included in other
wenzelm@47484
  2431
contexts.  This allows to manage context extensions casually, without
wenzelm@47855
  2432
the logical dependencies of locales and locale interpretation.  See
wenzelm@47855
  2433
commands 'bundle', 'include', 'including' etc. in the isar-ref manual.
wenzelm@47484
  2434
wenzelm@47829
  2435
* Commands 'lemmas' and 'theorems' allow local variables using 'for'
wenzelm@47829
  2436
declaration, and results are standardized before being stored.  Thus
wenzelm@47829
  2437
old-style "standard" after instantiation or composition of facts
wenzelm@47829
  2438
becomes obsolete.  Minor INCOMPATIBILITY, due to potential change of
wenzelm@47829
  2439
indices of schematic variables.
wenzelm@47829
  2440
wenzelm@47829
  2441
* Rule attributes in local theory declarations (e.g. locale or class)
wenzelm@47829
  2442
are now statically evaluated: the resulting theorem is stored instead
wenzelm@47829
  2443
of the original expression.  INCOMPATIBILITY in rare situations, where
wenzelm@47829
  2444
the historic accident of dynamic re-evaluation in interpretations
wenzelm@47829
  2445
etc. was exploited.
wenzelm@47829
  2446
wenzelm@47829
  2447
* New tutorial "Programming and Proving in Isabelle/HOL"
wenzelm@47829
  2448
("prog-prove").  It completely supersedes "A Tutorial Introduction to
wenzelm@47829
  2449
Structured Isar Proofs" ("isar-overview"), which has been removed.  It
wenzelm@47829
  2450
also supersedes "Isabelle/HOL, A Proof Assistant for Higher-Order
wenzelm@47829
  2451
Logic" as the recommended beginners tutorial, but does not cover all
wenzelm@47829
  2452
of the material of that old tutorial.
wenzelm@47829
  2453
wenzelm@47829
  2454
* Updated and extended reference manuals: "isar-ref",
wenzelm@47829
  2455
"implementation", "system"; reduced remaining material in old "ref"
wenzelm@47829
  2456
manual.
wenzelm@47829
  2457
wenzelm@47829
  2458
wenzelm@47829
  2459
*** Pure ***
wenzelm@47829
  2460
wenzelm@46976
  2461
* Command 'definition' no longer exports the foundational "raw_def"
wenzelm@46976
  2462
into the user context.  Minor INCOMPATIBILITY, may use the regular
wenzelm@46976
  2463
"def" result with attribute "abs_def" to imitate the old version.
wenzelm@46976
  2464
wenzelm@47855
  2465
* Attribute "abs_def" turns an equation of the form "f x y == t" into
wenzelm@47855
  2466
"f == %x y. t", which ensures that "simp" or "unfold" steps always
wenzelm@47855
  2467
expand it.  This also works for object-logic equality.  (Formerly
wenzelm@47855
  2468
undocumented feature.)
wenzelm@47855
  2469
wenzelm@47856
  2470
* Sort constraints are now propagated in simultaneous statements, just
wenzelm@47856
  2471
like type constraints.  INCOMPATIBILITY in rare situations, where
wenzelm@47856
  2472
distinct sorts used to be assigned accidentally.  For example:
wenzelm@47856
  2473
wenzelm@47856
  2474
  lemma "P (x::'a::foo)" and "Q (y::'a::bar)"  -- "now illegal"
wenzelm@47856
  2475
wenzelm@47856
  2476
  lemma "P (x::'a)" and "Q (y::'a::bar)"
wenzelm@47856
  2477
    -- "now uniform 'a::bar instead of default sort for first occurrence (!)"
wenzelm@47856
  2478
wenzelm@47856
  2479
* Rule composition via attribute "OF" (or ML functions OF/MRS) is more
wenzelm@47856
  2480
tolerant against multiple unifiers, as long as the final result is
wenzelm@47856
  2481
unique.  (As before, rules are composed in canonical right-to-left
wenzelm@47856
  2482
order to accommodate newly introduced premises.)
wenzelm@47856
  2483
wenzelm@47806
  2484
* Renamed some inner syntax categories:
wenzelm@47806
  2485
wenzelm@47806
  2486
    num ~> num_token
wenzelm@47806
  2487
    xnum ~> xnum_token
wenzelm@47806
  2488
    xstr ~> str_token
wenzelm@47806
  2489
wenzelm@47806
  2490
Minor INCOMPATIBILITY.  Note that in practice "num_const" or
wenzelm@47806
  2491
"num_position" etc. are mainly used instead (which also include
wenzelm@47806
  2492
position information via constraints).
wenzelm@47806
  2493
wenzelm@47829
  2494
* Simplified configuration options for syntax ambiguity: see
wenzelm@47829
  2495
"syntax_ambiguity_warning" and "syntax_ambiguity_limit" in isar-ref
wenzelm@47829
  2496
manual.  Minor INCOMPATIBILITY.
wenzelm@47829
  2497
wenzelm@47856
  2498
* Discontinued configuration option "syntax_positions": atomic terms
wenzelm@47856
  2499
in parse trees are always annotated by position constraints.
wenzelm@45134
  2500
wenzelm@47464
  2501
* Old code generator for SML and its commands 'code_module',
wenzelm@45383
  2502
'code_library', 'consts_code', 'types_code' have been discontinued.
haftmann@46028
  2503
Use commands of the generic code generator instead.  INCOMPATIBILITY.
wenzelm@45383
  2504
wenzelm@47464
  2505
* Redundant attribute "code_inline" has been discontinued. Use
wenzelm@47464
  2506
"code_unfold" instead.  INCOMPATIBILITY.
wenzelm@47464
  2507
wenzelm@47464
  2508
* Dropped attribute "code_unfold_post" in favor of the its dual
wenzelm@47464
  2509
"code_abbrev", which yields a common pattern in definitions like
haftmann@46028
  2510
haftmann@46028
  2511
  definition [code_abbrev]: "f = t"
haftmann@46028
  2512
haftmann@46028
  2513
INCOMPATIBILITY.
wenzelm@45383
  2514
wenzelm@47856
  2515
* Obsolete 'types' command has been discontinued.  Use 'type_synonym'
wenzelm@47856
  2516
instead.  INCOMPATIBILITY.
wenzelm@47856
  2517
wenzelm@47856
  2518
* Discontinued old "prems" fact, which used to refer to the accidental
wenzelm@47856
  2519
collection of foundational premises in the context (already marked as
wenzelm@47856
  2520
legacy since Isabelle2011).

* Type 'a set is now a proper type constructor (just as before
wenzelm@47464
  2526
Isabelle2008).  Definitions mem_def and Collect_def have disappeared.
wenzelm@47464
  2527
Non-trivial INCOMPATIBILITY.  For developments keeping predicates and
wenzelm@47855
  2528
sets separate, it is often sufficient to rephrase some set S that has
wenzelm@47855
  2529
been accidentally used as predicates by "%x. x : S", and some
wenzelm@47855
  2530
predicate P that has been accidentally used as set by "{x. P x}".
wenzelm@47855
  2531
Corresponding proofs in a first step should be pruned from any
wenzelm@47855
  2532
tinkering with former theorems mem_def and Collect_def as far as
wenzelm@47855
  2533
possible.
wenzelm@47855
  2534
wenzelm@47855
  2535
For developments which deliberately mix predicates and sets, a
wenzelm@47464
  2536
planning step is necessary to determine what should become a predicate
wenzelm@47464
  2537
and what a set.  It can be helpful to carry out that step in
wenzelm@47464
  2538
Isabelle2011-1 before jumping right into the current release.
wenzelm@47464
  2539
wenzelm@47855
  2540
* Code generation by default implements sets as container type rather
wenzelm@47855
  2541
than predicates.  INCOMPATIBILITY.
wenzelm@47855
  2542
wenzelm@47855
  2543
* New type synonym 'a rel = ('a * 'a) set
wenzelm@47855
  2544
wenzelm@47464
  2545
* The representation of numerals has changed.  Datatype "num"
wenzelm@47464
  2546
represents strictly positive binary numerals, along with functions
wenzelm@47464
  2547
"numeral :: num => 'a" and "neg_numeral :: num => 'a" to represent
wenzelm@47855
  2548
positive and negated numeric literals, respectively.  See also
wenzelm@47855
  2549
definitions in ~~/src/HOL/Num.thy.  Potential INCOMPATIBILITY, some
wenzelm@47855
  2550
user theories may require adaptations as follows:
huffman@47108
  2551
huffman@47108
  2552
  - Theorems with number_ring or number_semiring constraints: These
huffman@47108
  2553
    classes are gone; use comm_ring_1 or comm_semiring_1 instead.
huffman@47108
  2554
huffman@47108
  2555
  - Theories defining numeric types: Remove number, number_semiring,
huffman@47108
  2556
    and number_ring instances. Defer all theorems about numerals until
huffman@47108
  2557
    after classes one and semigroup_add have been instantiated.
huffman@47108
  2558
huffman@47108
  2559
  - Numeral-only simp rules: Replace each rule having a "number_of v"
huffman@47108
  2560
    pattern with two copies, one for numeral and one for neg_numeral.
huffman@47108
  2561
huffman@47108
  2562
  - Theorems about subclasses of semiring_1 or ring_1: These classes
huffman@47108
  2563
    automatically support numerals now, so more simp rules and
huffman@47108
  2564
    simprocs may now apply within the proof.
huffman@47108
  2565
huffman@47108
  2566
  - Definitions and theorems using old constructors Pls/Min/Bit0/Bit1:
huffman@47108
  2567
    Redefine using other integer operations.
huffman@47108
  2568
wenzelm@47855
  2569
* Transfer: New package intended to generalize the existing
wenzelm@47855
  2570
"descending" method and related theorem attributes from the Quotient
wenzelm@47855
  2571
package.  (Not all functionality is implemented yet, but future
wenzelm@47855
  2572
development will focus on Transfer as an eventual replacement for the
wenzelm@47855
  2573
corresponding parts of the Quotient package.)
wenzelm@47809
  2574
wenzelm@47809
  2575
  - transfer_rule attribute: Maintains a collection of transfer rules,
wenzelm@47809
  2576
    which relate constants at two different types. Transfer rules may
wenzelm@47809
  2577
    relate different type instances of the same polymorphic constant,
wenzelm@47809
  2578
    or they may relate an operation on a raw type to a corresponding
wenzelm@47809
  2579
    operation on an abstract type (quotient or subtype). For example:
wenzelm@47809
  2580
wenzelm@47809
  2581
    ((A ===> B) ===> list_all2 A ===> list_all2 B) map map
wenzelm@47809
  2582
    (cr_int ===> cr_int ===> cr_int) (%(x,y) (u,v). (x+u, y+v)) plus_int
wenzelm@47809
  2583
wenzelm@47809
  2584
  - transfer method: Replaces a subgoal on abstract types with an
wenzelm@47809
  2585
    equivalent subgoal on the corresponding raw types. Constants are
wenzelm@47809
  2586
    replaced with corresponding ones according to the transfer rules.
wenzelm@47809
  2587
    Goals are generalized over all free variables by default; this is
huffman@47851
  2588
    necessary for variables whose types change, but can be overridden
wenzelm@47855
  2589
    for specific variables with e.g. "transfer fixing: x y z".  The
wenzelm@47809
  2590
    variant transfer' method allows replacing a subgoal with one that
wenzelm@47809
  2591
    is logically stronger (rather than equivalent).
wenzelm@47809
  2592
wenzelm@47809
  2593
  - relator_eq attribute: Collects identity laws for relators of
wenzelm@47809
  2594
    various type constructors, e.g. "list_all2 (op =) = (op =)".  The
wenzelm@47809
  2595
    transfer method uses these lemmas to infer transfer rules for
wenzelm@47809
  2596
    non-polymorphic constants on the fly.
wenzelm@47809
  2597
wenzelm@47809
  2598
  - transfer_prover method: Assists with proving a transfer rule for a
wenzelm@47809
  2599
    new constant, provided the constant is defined in terms of other
wenzelm@47809
  2600
    constants that already have transfer rules. It should be applied
wenzelm@47809
  2601
    after unfolding the constant definitions.
wenzelm@47809
  2602
wenzelm@47809
  2603
  - HOL/ex/Transfer_Int_Nat.thy: Example theory demonstrating transfer
wenzelm@47809
  2604
    from type nat to type int.
wenzelm@47809
  2605
huffman@47851
  2606
* Lifting: New package intended to generalize the quotient_definition
huffman@47851
  2607
facility of the Quotient package; designed to work with Transfer.
wenzelm@47809
  2608
wenzelm@47809
  2609
  - lift_definition command: Defines operations on an abstract type in
wenzelm@47809
  2610
    terms of a corresponding operation on a representation
wenzelm@47809
  2611
    type.  Example syntax:
wenzelm@47809
  2612
wenzelm@47809
  2613
    lift_definition dlist_insert :: "'a => 'a dlist => 'a dlist"
wenzelm@47809
  2614
      is List.insert
wenzelm@47809
  2615
wenzelm@47809
  2616
    Users must discharge a respectfulness proof obligation when each
wenzelm@47809
  2617
    constant is defined. (For a type copy, i.e. a typedef with UNIV,
wenzelm@47809
  2618
    the proof is discharged automatically.) The obligation is
wenzelm@47809
  2619
    presented in a user-friendly, readable form; a respectfulness
wenzelm@47809
  2620
    theorem in the standard format and a transfer rule are generated
wenzelm@47809
  2621
    by the package.
wenzelm@47809
  2622
wenzelm@47809
  2623
  - Integration with code_abstype: For typedefs (e.g. subtypes
wenzelm@47809
  2624
    corresponding to a datatype invariant, such as dlist),
wenzelm@47809
  2625
    lift_definition generates a code certificate theorem and sets up
wenzelm@47809
  2626
    code generation for each constant.
wenzelm@47809
  2627
wenzelm@47809
  2628
  - setup_lifting command: Sets up the Lifting package to work with a
wenzelm@47809
  2629
    user-defined type. The user must provide either a quotient theorem
wenzelm@47809
  2630
    or a type_definition theorem.  The package configures transfer
wenzelm@47809
  2631
    rules for equality and quantifiers on the type, and sets up the
wenzelm@47809
  2632
    lift_definition command to work with the type.
wenzelm@47809
  2633
wenzelm@47809
  2634
  - Usage examples: See Quotient_Examples/Lift_DList.thy,
huffman@47851
  2635
    Quotient_Examples/Lift_RBT.thy, Quotient_Examples/Lift_FSet.thy,

  2636
    Word/Word.thy and Library/Float.thy.
wenzelm@47809
  2637
wenzelm@47809
  2638
* Quotient package:
wenzelm@47809
  2639
wenzelm@47809
  2640
  - The 'quotient_type' command now supports a 'morphisms' option with
wenzelm@47809
  2641
    rep and abs functions, similar to typedef.
wenzelm@47809
  2642
wenzelm@47809
  2643
  - 'quotient_type' sets up new types to work with the Lifting and
wenzelm@47809
  2644
    Transfer packages, as with 'setup_lifting'.
wenzelm@47809
  2645
wenzelm@47809
  2646
  - The 'quotient_definition' command now requires the user to prove a
wenzelm@47809
  2647
    respectfulness property at the point where the constant is
wenzelm@47809
  2648
    defined, similar to lift_definition; INCOMPATIBILITY.
wenzelm@47809
  2649
wenzelm@47809
  2650
  - Renamed predicate 'Quotient' to 'Quotient3', and renamed theorems
wenzelm@47809
  2651
    accordingly, INCOMPATIBILITY.
wenzelm@47809
  2652
wenzelm@47809
  2653
* New diagnostic command 'find_unused_assms' to find potentially
wenzelm@47809
  2654
superfluous assumptions in theorems using Quickcheck.
wenzelm@47809
  2655
wenzelm@47809
  2656
* Quickcheck:
wenzelm@47809
  2657
wenzelm@47809
  2658
  - Quickcheck returns variable assignments as counterexamples, which
wenzelm@47809
  2659
    allows to reveal the underspecification of functions under test.
wenzelm@47809
  2660
    For example, refuting "hd xs = x", it presents the variable
wenzelm@47809
  2661
    assignment xs = [] and x = a1 as a counterexample, assuming that
wenzelm@47809
  2662
    any property is false whenever "hd []" occurs in it.
wenzelm@47809
  2663
wenzelm@47809
  2664
    These counterexample are marked as potentially spurious, as
wenzelm@47809
  2665
    Quickcheck also returns "xs = []" as a counterexample to the
wenzelm@47809
  2666
    obvious theorem "hd xs = hd xs".
wenzelm@47809
  2667
wenzelm@47809
  2668
    After finding a potentially spurious counterexample, Quickcheck
wenzelm@47809
  2669
    continues searching for genuine ones.
wenzelm@47809
  2670
wenzelm@47809
  2671
    By default, Quickcheck shows potentially spurious and genuine
wenzelm@47809
  2672
    counterexamples. The option "genuine_only" sets quickcheck to only
wenzelm@47809
  2673
    show genuine counterexamples.
wenzelm@47809
  2674
wenzelm@47809
  2675
  - The command 'quickcheck_generator' creates random and exhaustive
wenzelm@47809
  2676
    value generators for a given type and operations.
wenzelm@47809
  2677
wenzelm@47809
  2678
    It generates values by using the operations as if they were
wenzelm@47809
  2679
    constructors of that type.
wenzelm@47809
  2680
wenzelm@47809
  2681
  - Support for multisets.
wenzelm@47809
  2682
wenzelm@47809
  2683
  - Added "use_subtype" options.
wenzelm@47809
  2684
wenzelm@47809
  2685
  - Added "quickcheck_locale" configuration to specify how to process
wenzelm@47809
  2686
    conjectures in a locale context.
wenzelm@47809
  2687
wenzelm@47855
  2688
* Nitpick: Fixed infinite loop caused by the 'peephole_optim' option
wenzelm@47855
  2689
and affecting 'rat' and 'real'.
wenzelm@47809
  2690
wenzelm@47809
  2691
* Sledgehammer:
wenzelm@47809
  2692
  - Integrated more tightly with SPASS, as described in the ITP 2012
wenzelm@47809
  2693
    paper "More SPASS with Isabelle".
wenzelm@47809
  2694
  - Made it try "smt" as a fallback if "metis" fails or times out.
wenzelm@47809
  2695
  - Added support for the following provers: Alt-Ergo (via Why3 and
wenzelm@47809
  2696
    TFF1), iProver, iProver-Eq.
wenzelm@47809
  2697
  - Sped up the minimizer.
wenzelm@47809
  2698
  - Added "lam_trans", "uncurry_aliases", and "minimize" options.
wenzelm@47809
  2699
  - Renamed "slicing" ("no_slicing") option to "slice" ("dont_slice").
wenzelm@47809
  2700
  - Renamed "sound" option to "strict".
wenzelm@47809
  2701
wenzelm@47855
  2702
* Metis: Added possibility to specify lambda translations scheme as a
wenzelm@47855
  2703
parenthesized argument (e.g., "by (metis (lifting) ...)").
wenzelm@47855
  2704
wenzelm@47855
  2705
* SMT: Renamed "smt_fixed" option to "smt_read_only_certificates".
wenzelm@47855
  2706
wenzelm@47855
  2707
* Command 'try0': Renamed from 'try_methods'. INCOMPATIBILITY.
wenzelm@47809
  2708
wenzelm@47856
  2709
* New "case_product" attribute to generate a case rule doing multiple
