*** General ***
wenzelm@62440
    11
wenzelm@62958
    12
* Type-inference improves sorts of newly introduced type variables for
wenzelm@62958
    13
the object-logic, using its base sort (i.e. HOL.type for Isabelle/HOL).
wenzelm@62958
    14
Thus terms like "f x" or "\<And>x. P x" without any further syntactic context
wenzelm@62958
    15
produce x::'a::type in HOL instead of x::'a::{} in Pure. Rare
wenzelm@62958
    16
INCOMPATIBILITY, need to provide explicit type constraints for Pure
wenzelm@62958
    17
types where this is really intended.
wenzelm@62958
    18
wenzelm@62969
    19
* Simplified outer syntax: uniform category "name" includes long
wenzelm@62969
    20
identifiers. Former "xname" / "nameref" / "name reference" has been
wenzelm@62969
    21
discontinued.
wenzelm@62969
    22
wenzelm@62807
    23
* Mixfix annotations support general block properties, with syntax
wenzelm@62807
    24
"(\<open>x=a y=b z \<dots>\<close>". Notable property names are "indent", "consistent",
wenzelm@62807
    25
"unbreakable", "markup". The existing notation "(DIGITS" is equivalent
wenzelm@62807
    26
to "(\<open>indent=DIGITS\<close>". The former notation "(00" for unbreakable blocks
wenzelm@62807
    27
is superseded by "(\<open>unbreabable\<close>" --- rare INCOMPATIBILITY.
wenzelm@62789
    28
wenzelm@62440
    29
* New symbol \<circle>, e.g. for temporal operator.
wenzelm@62440
    30
wenzelm@62453
    31
* Old 'header' command is no longer supported (legacy since
wenzelm@62453
    32
Isabelle2015).
wenzelm@62453
    33
wenzelm@62440
    34
wenzelm@62904
    35
*** Prover IDE -- Isabelle/Scala/jEdit ***
wenzelm@62904
    36
wenzelm@62932
    37
* IDE support for the Isabelle/Pure bootstrap process. The initial files
wenzelm@62962
    38
src/Pure/ROOT0.ML or src/Pure/ROOT.ML may be opened with Isabelle/jEdit:
wenzelm@62932
    39
they act like independent quasi-theories in the context of theory
wenzelm@62932
    40
ML_Bootstrap. This allows continuous checking of ML files as usual, but
wenzelm@62932
    41
results are isolated from the actual Isabelle/Pure that runs the IDE
wenzelm@62932
    42
itself.
wenzelm@62904
    43
wenzelm@62904
    44
wenzelm@62312
    45
*** Isar ***
wenzelm@62312
    46
wenzelm@62312
    47
* Command '\<proof>' is an alias for 'sorry', with different
wenzelm@62312
    48
typesetting. E.g. to produce proof holes in examples and documentation.
wenzelm@62216
    49
wenzelm@62939
    50
* The old proof method "default" has been removed (legacy since
wenzelm@62939
    51
Isabelle2016). INCOMPATIBILITY, use "standard" instead.
wenzelm@62939
    52
wenzelm@62216

blanchet@62327
    54
*** HOL ***
blanchet@62327
    55
wenzelm@62522
    56
* New abbreviations for negated existence (but not bounded existence):
wenzelm@62522
    57
wenzelm@62522
    58
  \<nexists>x. P x \<equiv> \<not> (\<exists>x. P x)
wenzelm@62522
    59
  \<nexists>!x. P x \<equiv> \<not> (\<exists>!x. P x)
wenzelm@62522
    60
wenzelm@62521
    61
* The print mode "HOL" for ASCII syntax of binders "!", "?", "?!", "@"
wenzelm@62521
    62
has been removed for output. It is retained for input only, until it is
wenzelm@62521
    63
eliminated altogether.
wenzelm@62521
    64
blanchet@62327
    65
* (Co)datatype package:
blanchet@62693
    66
  - New commands for defining corecursive functions and reasoning about
blanchet@62693
    67
    them in "~~/src/HOL/Library/BNF_Corec.thy": 'corec', 'corecursive',
blanchet@62693
    68
    'friend_of_corec', and 'corecursion_upto'; and 'corec_unique' proof
blanchet@62842
    69
    method. See 'isabelle doc corec'.
blanchet@62693
    70
  - The predicator :: ('a => bool) => 'a F => bool is now a first-class
traytel@62332
    71
    citizen in bounded natural functors
blanchet@62693
    72
  - 'primrec' now allows nested calls through the predicator in addition
blanchet@62327
    73
    to the map function.
blanchet@62693
    74
  - 'bnf' automatically discharges reflexive proof obligations
blanchet@62693
    75
  - 'bnf' outputs a slightly modified proof obligation expressing rel in
traytel@62332
    76
       terms of map and set
traytel@62332
    77
       (not giving a specification for rel makes this one reflexive)
blanchet@62693
    78
  - 'bnf' outputs a new proof obligation expressing pred in terms of set
traytel@62332
    79
       (not giving a specification for pred makes this one reflexive)
blanchet@62693
    80
    INCOMPATIBILITY: manual 'bnf' declarations may need adjustment
blanchet@62335
    81
  - Renamed lemmas:
blanchet@62335
    82
      rel_prod_apply ~> rel_prod_inject
blanchet@62335
    83
      pred_prod_apply ~> pred_prod_inject
blanchet@62335
    84
    INCOMPATIBILITY.
blanchet@62536
    85
  - The "size" plugin has been made compatible again with locales.
blanchet@62327
    86
wenzelm@62407
    87
* Renamed split_if -> if_split and split_if_asm -> if_split_asm to
wenzelm@62407
    88
resemble the f.split naming convention, INCOMPATIBILITY.
nipkow@62396
    89
haftmann@62597
    90
* Characters (type char) are modelled as finite algebraic type
haftmann@62597
    91
corresponding to {0..255}.
haftmann@62597
    92
haftmann@62597
    93
  - Logical representation:
haftmann@62597
    94
    * 0 is instantiated to the ASCII zero character.
wenzelm@62645
    95
    * All other characters are represented as "Char n"
haftmann@62597
    96
      with n being a raw numeral expression less than 256.
wenzelm@62645
    97
    * Expressions of the form "Char n" with n greater than 255
haftmann@62597
    98
      are non-canonical.
haftmann@62597
    99
  - Printing and parsing:
wenzelm@62645
   100
    * Printable characters are printed and parsed as "CHR ''\<dots>''"
haftmann@62597
   101
      (as before).
wenzelm@62645
   102
    * The ASCII zero character is printed and parsed as "0".
haftmann@62678
   103
    * All other canonical characters are printed as "CHR 0xXX"
haftmann@62678
   104
      with XX being the hexadecimal character code.  "CHR n"
haftmann@62597
   105
      is parsable for every numeral expression n.
haftmann@62598
   106
    * Non-canonical characters have no special syntax and are
haftmann@62597
   107
      printed as their logical representation.
haftmann@62597
   108
  - Explicit conversions from and to the natural numbers are
haftmann@62597
   109
    provided as char_of_nat, nat_of_char (as before).
haftmann@62597
   110
  - The auxiliary nibble type has been discontinued.
haftmann@62597
   111
haftmann@62597
   112
INCOMPATIBILITY.
haftmann@62597
   113
haftmann@62430
   114
* Multiset membership is now expressed using set_mset rather than count.
haftmann@62430
   115
haftmann@62430
   116
  - Expressions "count M a > 0" and similar simplify to membership
haftmann@62430
   117
    by default.
haftmann@62430
   118
haftmann@62430
   119
  - Converting between "count M a = 0" and non-membership happens using
haftmann@62430
   120
    equations count_eq_zero_iff and not_in_iff.
haftmann@62430
   121
haftmann@62430
   122
  - Rules count_inI and in_countE obtain facts of the form
haftmann@62430
   123
    "count M a = n" from membership.
haftmann@62430
   124
haftmann@62430
   125
  - Rules count_in_diffI and in_diff_countE obtain facts of the form
haftmann@62430
   126
    "count M a = n + count N a" from membership on difference sets.
haftmann@62430
   127
haftmann@62430
   128
INCOMPATIBILITY.
haftmann@62430
   129
haftmann@62343
   130
* Compound constants INFIMUM and SUPREMUM are mere abbreviations now.
haftmann@62343
   131
INCOMPATIBILITY.
haftmann@62343
   132
lp15@62408
   133
* More complex analysis including Cauchy's inequality, Liouville theorem,
lp15@62408
   134
open mapping theorem, maximum modulus principle, Schwarz Lemma.
lp15@62408
   135
haftmann@62358
   136
* "Gcd (f ` A)" and "Lcm (f ` A)" are printed with optional
haftmann@62358
   137
comprehension-like syntax analogously to "Inf (f ` A)" and "Sup (f ` A)".
haftmann@62358
   138
haftmann@62345
   139
* Class semiring_Lcd merged into semiring_Gcd.  INCOMPATIBILITY.
haftmann@62345
   140
hoelzl@62376
   141
* The type class ordered_comm_monoid_add is now called
hoelzl@62376
   142
ordered_cancel_comm_monoid_add. A new type class ordered_comm_monoid_add is
hoelzl@62376
   143
introduced as the combination of ordered_ab_semigroup_add + comm_monoid_add.
hoelzl@62376
   144
INCOMPATIBILITY.
hoelzl@62376
   145
hoelzl@62376
   146
* Introduced the type classes canonically_ordered_comm_monoid_add and dioid.
hoelzl@62376
   147
hoelzl@62376
   148
* Added topological_monoid
hoelzl@62376
   149
Andreas@62649
   150
* Library/Complete_Partial_Order2.thy provides reasoning support for
Andreas@62649
   151
proofs about monotonicity and continuity in chain-complete partial
Andreas@62649
   152
orders and about admissibility conditions for fixpoint inductions.
Andreas@62649
   153
haftmann@62352
   154
* Library/Polynomial.thy contains also derivation of polynomials
haftmann@62352
   155
but not gcd/lcm on polynomials over fields.  This has been moved
haftmann@62352
   156
to a separate theory Library/Polynomial_GCD_euclidean.thy, to
haftmann@62352
   157
pave way for a possible future different type class instantiation
haftmann@62352
   158
for polynomials over factorial rings.  INCOMPATIBILITY.
haftmann@62352
   159
haftmann@62348
   160
* Dropped various legacy fact bindings, whose replacements are often
haftmann@62348
   161

*** ML ***
wenzelm@62498
   256
wenzelm@62861
   257
* The ML function "ML" provides easy access to run-time compilation.
wenzelm@62861
   258
This is particularly useful for conditional compilation, without
wenzelm@62861
   259
requiring separate files.
wenzelm@62861
   260
wenzelm@62851
   261
* Low-level ML system structures (like PolyML and RunCall) are no longer
wenzelm@62886
   262
exposed to Isabelle/ML user-space. Potential INCOMPATIBILITY.
wenzelm@62851
   263
wenzelm@62662
   264
* Antiquotation @{make_string} is available during Pure bootstrap --
wenzelm@62662
   265
with approximative output quality.
wenzelm@62662
   266
wenzelm@62498
   267
* Option ML_exception_debugger controls detailed exception trace via the
wenzelm@62498
   268
Poly/ML debugger. Relevant ML modules need to be compiled beforehand
wenzelm@62498
   269
with ML_file_debug, or with ML_file and option ML_debugger enabled. Note
wenzelm@62498
   270
debugger information requires consirable time and space: main
wenzelm@62498
   271
Isabelle/HOL with full debugger support may need ML_system_64.
wenzelm@62498
   272
wenzelm@62514
   273
* Local_Theory.restore has been renamed to Local_Theory.reset to
wenzelm@62514
   274
emphasize its disruptive impact on the cumulative context, notably the
wenzelm@62514
   275
scope of 'private' or 'qualified' names. Note that Local_Theory.reset is
wenzelm@62514
   276
only appropriate when targets are managed, e.g. starting from a global
wenzelm@62514
   277
theory and returning to it. Regular definitional packages should use
wenzelm@62514
   278
balanced blocks of Local_Theory.open_target versus
wenzelm@62514
   279
Local_Theory.close_target instead. Rare INCOMPATIBILITY.
wenzelm@62514
   280
wenzelm@62519
   281
* Structure TimeLimit (originally from the SML/NJ library) has been
wenzelm@62519
   282
replaced by structure Timeout, with slightly different signature.
wenzelm@62519
   283
INCOMPATIBILITY.
wenzelm@62519
   284
wenzelm@62551
   285
* Discontinued cd and pwd operations, which are not well-defined in a
wenzelm@62551
   286
multi-threaded environment. Note that files are usually located
wenzelm@62551
   287
relatively to the master directory of a theory (see also
wenzelm@62551
   288
File.full_path). Potential INCOMPATIBILITY.
wenzelm@62551

wenzelm@62354
   291
*** System ***
wenzelm@62354
   292
wenzelm@62840
   293
* Many Isabelle tools that require a Java runtime system refer to the
wenzelm@62840
   294
settings ISABELLE_TOOL_JAVA_OPTIONS32 / ISABELLE_TOOL_JAVA_OPTIONS64,
wenzelm@62840
   295
depending on the underlying platform. The settings for "isabelle build"
wenzelm@62840
   296
ISABELLE_BUILD_JAVA_OPTIONS32 / ISABELLE_BUILD_JAVA_OPTIONS64 have been
wenzelm@62840
   297
discontinued. Potential INCOMPATIBILITY.
wenzelm@62840
   298
wenzelm@62591
   299
* The Isabelle system environment always ensures that the main
wenzelm@62591
   300
executables are found within the shell search $PATH: "isabelle" and
wenzelm@62591
   301
"isabelle_scala_script".
wenzelm@62591
   302
wenzelm@62591
   303
* The Isabelle ML process is now managed directly by Isabelle/Scala, and
wenzelm@62591
   304
shell scripts merely provide optional command-line access. In
wenzelm@62591
   305
particular:
wenzelm@62591
   306
wenzelm@62591
   307
  . Scala module ML_Process to connect to the raw ML process,
wenzelm@62591
   308
    with interaction via stdin/stdout/stderr or in batch mode;
wenzelm@62591
   309
  . command-line tool "isabelle console" as interactive wrapper;
wenzelm@62591
   310
  . command-line tool "isabelle process" as batch mode wrapper.
wenzelm@62588
   311
wenzelm@62588
   312
* The executable "isabelle_process" has been discontinued. Tools and
wenzelm@62588
   313
prover front-ends should use ML_Process or Isabelle_Process in
wenzelm@62591
   314
Isabelle/Scala. INCOMPATIBILITY.
wenzelm@62588
   315
wenzelm@62588
   316
* New command-line tool "isabelle process" supports ML evaluation of
wenzelm@62588
   317
literal expressions (option -e) or files (option -f) in the context of a
wenzelm@62588
   318
given heap image. Errors lead to premature exit of the ML process with
wenzelm@62588
   319
return code 1.
wenzelm@62588
   320
wenzelm@62588
   321
* Command-line tool "isabelle console" provides option -r to help to
wenzelm@62588
   322
bootstrapping Isabelle/Pure interactively.
wenzelm@62588
   323
wenzelm@62588
   324
* Command-line tool "isabelle yxml" has been discontinued.
wenzelm@62588
   325
INCOMPATIBILITY, use operations from the modules "XML" and "YXML" in
wenzelm@62588
   326
Isabelle/ML or Isabelle/Scala.
wenzelm@62588
   327
wenzelm@62549
   328
* File.bash_string, File.bash_path etc. represent Isabelle/ML and
wenzelm@62549
   329
Isabelle/Scala strings authentically within GNU bash. This is useful to
wenzelm@62549
   330
produce robust shell scripts under program control, without worrying
wenzelm@62549
   331
about spaces or special characters. Note that user output works via
wenzelm@62549
   332
Path.print (ML) or Path.toString (Scala). INCOMPATIBILITY, the old (and
wenzelm@62549
   333
less versatile) operations File.shell_quote, File.shell_path etc. have
wenzelm@62549
   334
been discontinued.
wenzelm@62549
   335
wenzelm@62591
   336
* SML/NJ and old versions of Poly/ML are no longer supported.
wenzelm@62591
   337
wenzelm@62642
   338
* Poly/ML heaps now follow the hierarchy of sessions, and thus require
wenzelm@62642
   339
much less disk space.
wenzelm@62642
   340
wenzelm@62354
   341
wenzelm@62354
   342
wenzelm@62031

-----------------------------------
wenzelm@60138
   345
wenzelm@61337
   346
*** General ***
wenzelm@61337
   347
wenzelm@62168
   348
* Eisbach is now based on Pure instead of HOL. Objects-logics may import
wenzelm@62168
   349
either the theory ~~/src/HOL/Eisbach/Eisbach (for HOL etc.) or
wenzelm@62168
   350
~~/src/HOL/Eisbach/Eisbach_Old_Appl_Syntax (for FOL, ZF etc.). Note that
wenzelm@62168
   351
the HOL-Eisbach session located in ~~/src/HOL/Eisbach/ contains further
wenzelm@62168
   352
examples that do require HOL.
wenzelm@62168
   353
wenzelm@62157
   354
* Better resource usage on all platforms (Linux, Windows, Mac OS X) for
wenzelm@62157
   355
both Isabelle/ML and Isabelle/Scala.  Slightly reduced heap space usage.
wenzelm@62157
   356
wenzelm@62017
   357
* Former "xsymbols" syntax with Isabelle symbols is used by default,
wenzelm@62017
   358
without any special print mode. Important ASCII replacement syntax
wenzelm@62017
   359
remains available under print mode "ASCII", but less important syntax
wenzelm@62017
   360
has been removed (see below).
wenzelm@62017
   361
wenzelm@62109
   362
* Support for more arrow symbols, with rendering in LaTeX and Isabelle
wenzelm@62109
   363
fonts: \<Lleftarrow> \<Rrightarrow> \<longlongleftarrow> \<longlongrightarrow> \<longlonglongleftarrow> \<longlonglongrightarrow>.
wenzelm@62017
   364
wenzelm@62108
   365
* Special notation \<struct> for the first implicit 'structure' in the
wenzelm@62108
   366
context has been discontinued. Rare INCOMPATIBILITY, use explicit
wenzelm@62108
   367
structure name instead, notably in indexed notation with block-subscript
wenzelm@62108
   368
(e.g. \<odot>\<^bsub>A\<^esub>).
wenzelm@62108
   369
wenzelm@62108
   370
* The glyph for \<diamond> in the IsabelleText font now corresponds better to its
wenzelm@62108
   371
counterpart \<box> as quantifier-like symbol. A small diamond is available as
wenzelm@62108
   372
\<diamondop>; the old symbol \<struct> loses this rendering and any special
wenzelm@62108
   373
meaning.
wenzelm@62108
   374
wenzelm@62017
   375
* Syntax for formal comments "-- text" now also supports the symbolic
wenzelm@62017
   376
form "\<comment> text". Command-line tool "isabelle update_cartouches -c" helps
wenzelm@62017
   377
to update old sources.
wenzelm@62017
   378
wenzelm@61337
   379
* Toplevel theorem statements have been simplified as follows:
wenzelm@61337
   380
wenzelm@61337
   381
  theorems             ~>  lemmas
wenzelm@61337
   382
  schematic_lemma      ~>  schematic_goal
wenzelm@61337
   383
  schematic_theorem    ~>  schematic_goal
wenzelm@61337
   384
  schematic_corollary  ~>  schematic_goal
wenzelm@61337
   385
wenzelm@61337
   386
Command-line tool "isabelle update_theorems" updates theory sources
wenzelm@61337
   387
accordingly.
wenzelm@61337
   388
wenzelm@61338
   389
* Toplevel theorem statement 'proposition' is another alias for
wenzelm@61338
   390
'theorem'.
wenzelm@61338
   391
wenzelm@62169
   392
* The old 'defs' command has been removed (legacy since Isabelle2014).
wenzelm@62169
   393
INCOMPATIBILITY, use regular 'definition' instead. Overloaded and/or
wenzelm@62169
   394
deferred definitions require a surrounding 'overloading' block.
wenzelm@62169
   395
wenzelm@61337
   396
wenzelm@60610
   397
*** Prover IDE -- Isabelle/Scala/jEdit ***
wenzelm@60610
   398
wenzelm@60986
   399
* IDE support for the source-level debugger of Poly/ML, to work with
wenzelm@62253
   400
Isabelle/ML and official Standard ML. Option "ML_debugger" and commands
wenzelm@62253
   401
'ML_file_debug', 'ML_file_no_debug', 'SML_file_debug',
wenzelm@62253
   402
'SML_file_no_debug' control compilation of sources with or without
wenzelm@62253
   403
debugging information. The Debugger panel allows to set breakpoints (via
wenzelm@62253
   404
context menu), step through stopped threads, evaluate local ML
wenzelm@62253
   405
expressions etc. At least one Debugger view needs to be active to have
wenzelm@62253
   406
any effect on the running ML program.
wenzelm@60984
   407
wenzelm@61804
   408
* The State panel manages explicit proof state output, with dynamic
wenzelm@61804
   409
auto-update according to cursor movement. Alternatively, the jEdit
wenzelm@61804
   410
action "isabelle.update-state" (shortcut S+ENTER) triggers manual
wenzelm@61804
   411
update.
wenzelm@61729
   412
wenzelm@61729
   413
* The Output panel no longer shows proof state output by default, to
wenzelm@61729
   414
avoid GUI overcrowding. INCOMPATIBILITY, use the State panel instead or
wenzelm@61729
   415
enable option "editor_output_state".
wenzelm@61215
   416
wenzelm@61804
   417
* The text overview column (status of errors, warnings etc.) is updated
wenzelm@61804
   418
asynchronously, leading to much better editor reactivity. Moreover, the
wenzelm@61804
   419
full document node content is taken into account. The width of the
wenzelm@61804
   420
column is scaled according to the main text area font, for improved
wenzelm@61804
   421
visibility.
wenzelm@61804
   422
wenzelm@61804
   423
* The main text area no longer changes its color hue in outdated
wenzelm@61804
   424
situations. The text overview column takes over the role to indicate
wenzelm@61804
   425
unfinished edits in the PIDE pipeline. This avoids flashing text display
wenzelm@61804
   426
due to ad-hoc updates by auxiliary GUI components, such as the State
wenzelm@61804
   427
panel.
wenzelm@61804
   428
wenzelm@62254
   429
* Slightly improved scheduling for urgent print tasks (e.g. command
wenzelm@62254
   430
state output, interactive queries) wrt. long-running background tasks.
wenzelm@62017
   431
wenzelm@62017
   432
* Completion of symbols via prefix of \<name> or \<^name> or \name is
wenzelm@62017
   433
always possible, independently of the language context. It is never
wenzelm@62017
   434
implicit: a popup will show up unconditionally.
wenzelm@62017
   435
wenzelm@62017
   436
* Additional abbreviations for syntactic completion may be specified in
wenzelm@62017
   437
$ISABELLE_HOME/etc/abbrevs and $ISABELLE_HOME_USER/etc/abbrevs, with
wenzelm@62017
   438
support for simple templates using ASCII 007 (bell) as placeholder.
wenzelm@62017
   439
wenzelm@62234
   440
* Symbols \<oplus>, \<Oplus>, \<otimes>, \<Otimes>, \<odot>, \<Odot>, \<ominus>, \<oslash> no longer provide abbreviations for
wenzelm@62234
   441
completion like "+o", "*o", ".o" etc. -- due to conflicts with other
wenzelm@62234
   442
ASCII syntax. INCOMPATIBILITY, use plain backslash-completion or define
wenzelm@62234
   443
suitable abbreviations in $ISABELLE_HOME_USER/etc/abbrevs.
wenzelm@62234
   444
wenzelm@61483
   445
* Action "isabelle-emph" (with keyboard shortcut C+e LEFT) controls
wenzelm@61483
   446
emphasized text style; the effect is visible in document output, not in
wenzelm@61483
   447
the editor.
wenzelm@61483
   448
wenzelm@61483
   449
* Action "isabelle-reset" now uses keyboard shortcut C+e BACK_SPACE,
wenzelm@61483
   450
instead of former C+e LEFT.
wenzelm@61483
   451
wenzelm@61512
   452
* The command-line tool "isabelle jedit" and the isabelle.Main
wenzelm@62027
   453
application wrapper treat the default $USER_HOME/Scratch.thy more
wenzelm@61512
   454
uniformly, and allow the dummy file argument ":" to open an empty buffer
wenzelm@61512
   455
instead.
wenzelm@61512
   456
wenzelm@62017
   457
* New command-line tool "isabelle jedit_client" allows to connect to an
wenzelm@62017
   458
already running Isabelle/jEdit process. This achieves the effect of
wenzelm@62017
   459
single-instance applications seen on common GUI desktops.
wenzelm@62017
   460
wenzelm@61530
   461
* The default look-and-feel for Linux is the traditional "Metal", which
wenzelm@61530
   462
works better with GUI scaling for very high-resolution displays (e.g.
wenzelm@61530
   463
4K). Moreover, it is generally more robust than "Nimbus".
wenzelm@61530
   464
wenzelm@62163
   465
* Update to jedit-5.3.0, with improved GUI scaling and support of
wenzelm@62163
   466
high-resolution displays (e.g. 4K).
wenzelm@62163
   467
wenzelm@62034
   468
* The main Isabelle executable is managed as single-instance Desktop
wenzelm@62034
   469
application uniformly on all platforms: Linux, Windows, Mac OS X.
wenzelm@62034

wenzelm@61405
   472
*** Document preparation ***
wenzelm@61405
   473
wenzelm@62017
   474
* Commands 'paragraph' and 'subparagraph' provide additional section
wenzelm@62017
   475
headings. Thus there are 6 levels of standard headings, as in HTML.
wenzelm@62017
   476
wenzelm@62017
   477
* Command 'text_raw' has been clarified: input text is processed as in
wenzelm@62017
   478
'text' (with antiquotations and control symbols). The key difference is
wenzelm@62017
   479
the lack of the surrounding isabelle markup environment in output.
wenzelm@62017
   480
wenzelm@62017
   481
* Text is structured in paragraphs and nested lists, using notation that
wenzelm@62017
   482
is similar to Markdown. The control symbols for list items are as
wenzelm@62017
   483
follows:
wenzelm@62017
   484
wenzelm@62017
   485
  \<^item>  itemize
wenzelm@62017
   486
  \<^enum>  enumerate
wenzelm@62017
   487
  \<^descr>  description
wenzelm@62017
   488
wenzelm@61491
   489
* There is a new short form for antiquotations with a single argument
wenzelm@61491
   490
that is a cartouche: \<^name>\<open>...\<close> is equivalent to @{name \<open>...\<close>} and
wenzelm@61595
   491
\<open>...\<close> without control symbol is equivalent to @{cartouche \<open>...\<close>}.
wenzelm@61595
   492
\<^name> without following cartouche is equivalent to @{name}. The
wenzelm@61501
   493
standard Isabelle fonts provide glyphs to render important control
wenzelm@61501
   494
symbols, e.g. "\<^verbatim>", "\<^emph>", "\<^bold>".
wenzelm@61491
   495
wenzelm@61595
   496
* Antiquotations @{noindent}, @{smallskip}, @{medskip}, @{bigskip} with
wenzelm@61595
   497
corresponding control symbols \<^noindent>, \<^smallskip>, \<^medskip>, \<^bigskip> specify spacing formally, using
wenzelm@61595
   498
standard LaTeX macros of the same names.
wenzelm@61595
   499
wenzelm@61491
   500
* Antiquotation @{cartouche} in Isabelle/Pure is the same as @{text}.
wenzelm@61491
   501
Consequently, \<open>...\<close> without any decoration prints literal quasi-formal
wenzelm@61492
   502
text. Command-line tool "isabelle update_cartouches -t" helps to update
wenzelm@61492
   503
old sources, by approximative patching of the content of string and
wenzelm@61492
   504
cartouche tokens seen in theory sources.
wenzelm@61491
   505
wenzelm@61491
   506
* The @{text} antiquotation now ignores the antiquotation option
wenzelm@61491
   507
"source". The given text content is output unconditionally, without any
wenzelm@61491
   508
surrounding quotes etc. Subtle INCOMPATIBILITY, put quotes into the
wenzelm@61494
   509
argument where they are really intended, e.g. @{text \<open>"foo"\<close>}. Initial
wenzelm@61494
   510
or terminal spaces are ignored.
wenzelm@61491
   511
wenzelm@62017
   512
* Antiquotations @{emph} and @{bold} output LaTeX source recursively,
wenzelm@62017
   513
adding appropriate text style markup. These may be used in the short
wenzelm@62017
   514
form \<^emph>\<open>...\<close> and \<^bold>\<open>...\<close>.
wenzelm@62017
   515
wenzelm@62017
   516
* Document antiquotation @{footnote} outputs LaTeX source recursively,
wenzelm@62017
   517
marked as \footnote{}. This may be used in the short form \<^footnote>\<open>...\<close>.
wenzelm@62017
   518
wenzelm@62017
   519
* Antiquotation @{verbatim [display]} supports option "indent".
wenzelm@62017
   520
wenzelm@62017
   521
* Antiquotation @{theory_text} prints uninterpreted theory source text

wenzelm@62017

wenzelm@62017

documentation, with a hyperlink in the Prover IDE.
wenzelm@62017
   527
wenzelm@62017

* Local goals ('have', 'show', 'hence', 'thus') allow structured rule
wenzelm@62205
   539
statements like fixes/assumes/shows in theorem specifications, but the
wenzelm@62205
   540
notation is postfix with keywords 'if' (or 'when') and 'for'. For
wenzelm@60555
   541
example:
wenzelm@60414
   542
wenzelm@60414
   543
  have result: "C x y"
wenzelm@60414
   544
    if "A x" and "B y"
wenzelm@60414
   545
    for x :: 'a and y :: 'a
wenzelm@60414
   546
    <proof>
wenzelm@60414
   547
wenzelm@60449
   548
The local assumptions are bound to the name "that". The result is
wenzelm@60449
   549
exported from context of the statement as usual. The above roughly
wenzelm@60414
   550
corresponds to a raw proof block like this:
wenzelm@60414
   551
wenzelm@60414
   552
  {
wenzelm@60414
   553
    fix x :: 'a and y :: 'a
wenzelm@60449
   554
    assume that: "A x" "B y"
wenzelm@60414
   555
    have "C x y" <proof>
wenzelm@60414
   556
  }
wenzelm@60414
   557
  note result = this
wenzelm@60406
   558
wenzelm@60555
   559
The keyword 'when' may be used instead of 'if', to indicate 'presume'
wenzelm@60555
   560
instead of 'assume' above.
wenzelm@60555
   561
wenzelm@61733
   562
* Assumptions ('assume', 'presume') allow structured rule statements
wenzelm@61733
   563
using 'if' and 'for', similar to 'have' etc. above. For example:
wenzelm@61658
   564
wenzelm@61658
   565
  assume result: "C x y"
wenzelm@61658
   566
    if "A x" and "B y"
wenzelm@61658
   567
    for x :: 'a and y :: 'a
wenzelm@61658
   568
wenzelm@61658
   569
This assumes "\<And>x y::'a. A x \<Longrightarrow> B y \<Longrightarrow> C x y" and produces a general
wenzelm@61658
   570
result as usual: "A ?x \<Longrightarrow> B ?y \<Longrightarrow> C ?x ?y".
wenzelm@61658
   571
wenzelm@61658
   572
Vacuous quantification in assumptions is omitted, i.e. a for-context
wenzelm@61658
   573
only effects propositions according to actual use of variables. For
wenzelm@61658
   574
example:
wenzelm@61658
   575
wenzelm@61658
   576
  assume "A x" and "B y" for x and y
wenzelm@61658
   577
wenzelm@61658
   578
is equivalent to:
wenzelm@61658
   579
wenzelm@61658
   580
  assume "\<And>x. A x" and "\<And>y. B y"
wenzelm@61658
   581
wenzelm@60595
   582
* The meaning of 'show' with Pure rule statements has changed: premises
wenzelm@60595
   583
are treated in the sense of 'assume', instead of 'presume'. This means,
wenzelm@62205
   584
a goal like "\<And>x. A x \<Longrightarrow> B x \<Longrightarrow> C x" can be solved completely as
wenzelm@62205
   585
follows:
wenzelm@60595
   586
wenzelm@60595
   587
  show "\<And>x. A x \<Longrightarrow> B x \<Longrightarrow> C x"
wenzelm@60595
   588
wenzelm@60595
   589
or:
wenzelm@60595
   590
wenzelm@60595
   591
  show "C x" if "A x" "B x" for x
wenzelm@60595
   592
wenzelm@60595
   593
Rare INCOMPATIBILITY, the old behaviour may be recovered as follows:
wenzelm@60595
   594
wenzelm@60595
   595
  show "C x" when "A x" "B x" for x
wenzelm@60595
   596
wenzelm@60459
   597
* New command 'consider' states rules for generalized elimination and
wenzelm@60459
   598
case splitting. This is like a toplevel statement "theorem obtains" used
wenzelm@60459
   599
within a proof body; or like a multi-branch 'obtain' without activation
wenzelm@60459
   600
of the local context elements yet.
wenzelm@60459
   601
wenzelm@60455
   602
* Proof method "cases" allows to specify the rule as first entry of
wenzelm@60455
   603
chained facts.  This is particularly useful with 'consider':
wenzelm@60455
   604
wenzelm@60455
   605
  consider (a) A | (b) B | (c) C <proof>
wenzelm@60455

wenzelm@60455

   619
wenzelm@60565
   620
  case a: (c xs)
wenzelm@60565
   621
  case a [attributes]: (c xs)
wenzelm@60565
   622
wenzelm@60565
   623
Facts that are introduced by invoking the case context are uniformly
wenzelm@60565
   624
qualified by "a"; the same name is used for the cumulative fact. The old
wenzelm@60565
   625
form "case (c xs) [attributes]" is no longer supported. Rare
wenzelm@60565
   626
INCOMPATIBILITY, need to adapt uses of case facts in exotic situations,
wenzelm@60565
   627
and always put attributes in front.
wenzelm@60565
   628
wenzelm@60618
   629
* The standard proof method of commands 'proof' and '..' is now called
wenzelm@60618
   630
"standard" to make semantically clear what it is; the old name "default"
wenzelm@60618
   631
is still available as legacy for some time. Documentation now explains
wenzelm@60618
   632
'..' more accurately as "by standard" instead of "by rule".
wenzelm@60618
   633
wenzelm@62017
   634
* Nesting of Isar goal structure has been clarified: the context after
wenzelm@62017
   635
the initial backwards refinement is retained for the whole proof, within
wenzelm@62017
   636
all its context sections (as indicated via 'next'). This is e.g.
wenzelm@62017
   637
relevant for 'using', 'including', 'supply':
wenzelm@62017
   638
wenzelm@62017
   639
  have "A \<and> A" if a: A for A
wenzelm@62017

* Command 'obtain' binds term abbreviations (via 'is' patterns) in the
wenzelm@62017
   648
proof body as well, abstracted over relevant parameters.
wenzelm@62017
   649
wenzelm@62017
   650
* Improved type-inference for theorem statement 'obtains': separate
wenzelm@62017
   651
parameter scope for of each clause.
wenzelm@62017
   652
wenzelm@62017
   653
* Term abbreviations via 'is' patterns also work for schematic
wenzelm@62017
   654
statements: result is abstracted over unknowns.
wenzelm@62017
   655
wenzelm@60631
   656
* Command 'subgoal' allows to impose some structure on backward
wenzelm@60631
   657
refinements, to avoid proof scripts degenerating into long of 'apply'
wenzelm@60631
   658
sequences. Further explanations and examples are given in the isar-ref
wenzelm@60631
   659
manual.
wenzelm@60631

* The undocumented feature of implicit cases goal1, goal2, goal3, etc.
wenzelm@60617
   689
is marked as legacy, and will be removed eventually. The proof method
wenzelm@60617
   690
"goals" achieves a similar effect within regular Isar; often it can be
wenzelm@60617

done more adequately by other means (e.g. 'consider').

* More gentle suppression of syntax along locale morphisms while
wenzelm@62017

printing terms. Previously 'abbreviation' and 'notation' declarations
wenzelm@62017

would be suppressed for morphisms except term identity. Now
ballarin@61701
   713
'abbreviation' is also kept for morphims that only change the involved
wenzelm@62017
   714
parameters, and only 'notation' is suppressed. This can be of great help
wenzelm@62017
   715
when working with complex locale hierarchies, because proof states are
wenzelm@62017
   716
displayed much more succinctly. It also means that only notation needs
wenzelm@62017
   717
to be redeclared if desired, as illustrated by this example:

global collection of overloaded constant / type definitions into
wenzelm@62017
   760
account. Type definitions with open dependencies on overloaded
wenzelm@62017
   761
definitions need to be specified as "typedef (overloaded)". This

provides extra robustness in theory construction. Rare INCOMPATIBILITY.

old-style "hide_const (open) ...". Consequently, both the defined

constant and its defining fact become qualified, e.g. Option.is_none and

blanchet@61318
   913
  - The MaSh relevance filter has been sped up.
blanchet@60306
   914
  - Proof reconstruction has been improved, to minimize the incidence of

blanchet@61345
   931
    structure on the raw type to an abstract type defined using typedef.
blanchet@61345
   932
  - Always generate "case_transfer" theorem.
wenzelm@62235
   933
  - For mutual types, generate slightly stronger "rel_induct",
wenzelm@62235
   934
    "rel_coinduct", and "coinduct" theorems. INCOMPATIBLITY.
blanchet@61552
   935
  - Allow discriminators and selectors with the same name as the type
blanchet@61552

   937
  - Avoid various internal name clashes (e.g., 'datatype f = f').

haftmann@60688
   953
* Class algebraic_semidom introduces common algebraic notions of
wenzelm@62017
   954
integral (semi)domains, particularly units. Although logically subsumed
wenzelm@62017
   955

wenzelm@62017
   968
logically unified to Rings.divide in syntactic type class Rings.divide,
wenzelm@62017
   969
with infix syntax (_ div _). Infix syntax (_ / _) for field division is
wenzelm@62017
   970
added later as abbreviation in class Fields.inverse. INCOMPATIBILITY,
wenzelm@62017
   971
instantiations must refer to Rings.divide rather than the former
wenzelm@62017
   972
separate constants, hence infix syntax (_ / _) is usually not available
wenzelm@62017

during instantiation.
wenzelm@62017
   974
wenzelm@62017

* The following combinators for low-level profiling of the ML runtime
wenzelm@62017
  1074
system are available:
wenzelm@62017
  1075
wenzelm@62017
  1076
  profile_time          (*CPU time*)
wenzelm@62017

  profile_time_thread   (*CPU time on this thread*)
wenzelm@62017
  1078
  profile_allocations   (*overall heap allocations*)
wenzelm@62017
  1079
wenzelm@62017
  1080
* Antiquotation @{undefined} or \<^undefined> inlines (raise Match).
wenzelm@62017
  1081
wenzelm@62075
  1082
* Antiquotation @{method NAME} inlines the (checked) name of the given
wenzelm@62075
  1083
Isar proof method.
wenzelm@62075
  1084
wenzelm@61922
  1085
* Pretty printing of Poly/ML compiler output in Isabelle has been
wenzelm@61922
  1086
improved: proper treatment of break offsets and blocks with consistent
wenzelm@61922
  1087
breaks.
wenzelm@61922
  1088
wenzelm@61268
  1089
* The auxiliary module Pure/display.ML has been eliminated. Its
wenzelm@61268
  1090
elementary thm print operations are now in Pure/more_thm.ML and thus
wenzelm@61268
  1091
called Thm.pretty_thm, Thm.string_of_thm etc. INCOMPATIBILITY.
wenzelm@61268
  1092
wenzelm@61144
  1093
* Simproc programming interfaces have been simplified:
wenzelm@61144
  1094
Simplifier.make_simproc and Simplifier.define_simproc supersede various
wenzelm@61144
  1095
forms of Simplifier.mk_simproc, Simplifier.simproc_global etc. Note that
wenzelm@61144
  1096
term patterns for the left-hand sides are specified with implicitly
wenzelm@61144
  1097
fixed variables, like top-level theorem statements. INCOMPATIBILITY.
wenzelm@61144
  1098
wenzelm@60802
  1099
* Instantiation rules have been re-organized as follows:
wenzelm@60802
  1100
wenzelm@60802
  1101
  Thm.instantiate  (*low-level instantiation with named arguments*)
wenzelm@60802
  1102
  Thm.instantiate' (*version with positional arguments*)
wenzelm@60802
  1103
wenzelm@60802
  1104
  Drule.infer_instantiate  (*instantiation with type inference*)
wenzelm@60802
  1105
  Drule.infer_instantiate'  (*version with positional arguments*)
wenzelm@60802
  1106
wenzelm@60802
  1107
The LHS only requires variable specifications, instead of full terms.
wenzelm@60802
  1108
Old cterm_instantiate is superseded by infer_instantiate.
wenzelm@60802
  1109
INCOMPATIBILITY, need to re-adjust some ML names and types accordingly.
wenzelm@60802
  1110
wenzelm@60793
  1111
* Old tactic shorthands atac, rtac, etac, dtac, ftac have been
wenzelm@60793
  1112
discontinued. INCOMPATIBILITY, use regular assume_tac, resolve_tac etc.
wenzelm@60793
  1113
instead (with proper context).
wenzelm@60642
  1114
wenzelm@60642
  1115
* Thm.instantiate (and derivatives) no longer require the LHS of the
wenzelm@60642
  1116
instantiation to be certified: plain variables are given directly.
wenzelm@60642
  1117
wenzelm@60707
  1118
* Subgoal.SUBPROOF and Subgoal.FOCUS combinators use anonymous
wenzelm@60707
  1119
quasi-bound variables (like the Simplifier), instead of accidentally
wenzelm@60707
  1120
named local fixes. This has the potential to improve stability of proof
wenzelm@60707
  1121
tools, but can also cause INCOMPATIBILITY for tools that don't observe
wenzelm@60707
  1122
the proof context discipline.
wenzelm@60707
  1123
wenzelm@62017
  1124
* Isar proof methods are based on a slightly more general type
wenzelm@62017
  1125
context_tactic, which allows to change the proof context dynamically
wenzelm@62017
  1126
(e.g. to update cases) and indicate explicit Seq.Error results. Former
wenzelm@62017
  1127
METHOD_CASES is superseded by CONTEXT_METHOD; further combinators are
wenzelm@62017
  1128
provided in src/Pure/Isar/method.ML for convenience. INCOMPATIBILITY.

  1142
maintainability of proofs.
wenzelm@62017
  1143
wenzelm@61602
  1144
* Global session timeout is multiplied by timeout_scale factor. This
wenzelm@61602
  1145
allows to adjust large-scale tests (e.g. AFP) to overall hardware
wenzelm@61602

performance.
wenzelm@61602
  1147
wenzelm@61174
  1148
* Property values in etc/symbols may contain spaces, if written with the
wenzelm@62671
  1149
replacement character "␣" (Unicode point 0x2324). For example:
wenzelm@62671
  1150
wenzelm@62671
  1151
    \<star>  code: 0x0022c6  group: operator  font: Deja␣Vu␣Sans␣Mono

* Java runtime environment for x86_64-windows allows to use larger heap
wenzelm@60996

space.
wenzelm@60996
  1155
wenzelm@61135
  1156
* Java runtime options are determined separately for 32bit vs. 64bit
wenzelm@61135
  1157
platforms as follows.
wenzelm@61135
  1158
wenzelm@61135

* Bash shell function "jvmpath" has been renamed to "platform_path": it
wenzelm@61294
  1170
is relevant both for Poly/ML and JVM processes.
wenzelm@61294
  1171
wenzelm@62017
  1172
* Poly/ML default platform architecture may be changed from 32bit to
wenzelm@62205
  1173
64bit via system option ML_system_64. A system restart (and rebuild) is
wenzelm@62205
  1174
required after change.
wenzelm@62017
  1175
wenzelm@62017
  1176
* Poly/ML 5.6 runs natively on x86-windows and x86_64-windows, which
wenzelm@62017
  1177
both allow larger heap space than former x86-cygwin.
wenzelm@62017
  1178
wenzelm@62157
  1179
* Heap images are 10-15% smaller due to less wasteful persistent theory

*** General ***
wenzelm@57941
  1188
wenzelm@59939
  1189
* Local theory specification commands may have a 'private' or
wenzelm@59990
  1190
'qualified' modifier to restrict name space accesses to the local scope,
wenzelm@59939
  1191
as provided by some "context begin ... end" block. For example:
wenzelm@59926
  1192
wenzelm@59926
  1193
  context
wenzelm@59926
  1194
  begin
wenzelm@59926
  1195
wenzelm@59926
  1196
  private definition ...

wenzelm@59926
  1206
wenzelm@59901

* Command 'experiment' opens an anonymous locale context with private
wenzelm@59901
  1208
naming policy.
wenzelm@59901
  1209
wenzelm@59951
  1210
* Command 'notepad' requires proper nesting of begin/end and its proof
wenzelm@59951
  1211
structure in the body: 'oops' is no longer supported here. Minor
wenzelm@59951
  1212
INCOMPATIBILITY, use 'sorry' instead.
wenzelm@59951
  1213
wenzelm@59951
  1214
* Command 'named_theorems' declares a dynamic fact within the context,
wenzelm@59951
  1215
together with an attribute to maintain the content incrementally. This
wenzelm@59951
  1216
supersedes functor Named_Thms in Isabelle/ML, but with a subtle change
wenzelm@59951
  1217
of semantics due to external visual order vs. internal reverse order.
wenzelm@59951
  1218
wenzelm@59951
  1219
* 'find_theorems': search patterns which are abstractions are
wenzelm@59951
  1220
schematically expanded before search. Search results match the naive
wenzelm@59951
  1221
expectation more closely, particularly wrt. abbreviations.
wenzelm@59951
  1222
INCOMPATIBILITY.
wenzelm@59648
  1223
wenzelm@59569
  1224
* Commands 'method_setup' and 'attribute_setup' now work within a local
wenzelm@59569
  1225
theory context.
wenzelm@57941
  1226
wenzelm@58928
  1227
* Outer syntax commands are managed authentically within the theory
wenzelm@59569
  1228
context, without implicit global state. Potential for accidental
wenzelm@58928
  1229
INCOMPATIBILITY, make sure that required theories are really imported.
wenzelm@58928
  1230
wenzelm@60116
  1231
* Historical command-line terminator ";" is no longer accepted (and
wenzelm@60116
  1232
already used differently in Isar). Minor INCOMPATIBILITY, use "isabelle
wenzelm@60116
  1233
update_semicolons" to remove obsolete semicolons from old theory
wenzelm@60116
  1234
sources.
wenzelm@60116
  1235
wenzelm@59951
  1236
* Structural composition of proof methods (meth1; meth2) in Isar
wenzelm@59951
  1237
corresponds to (tac1 THEN_ALL_NEW tac2) in ML.
haftmann@59105
  1238
wenzelm@60119
  1239
* The Eisbach proof method language allows to define new proof methods
wenzelm@60119
  1240
by combining existing ones with their usual syntax. The "match" proof
wenzelm@60119
  1241
method provides basic fact/term matching in addition to
wenzelm@60119
  1242
premise/conclusion matching through Subgoal.focus, and binds fact names
wenzelm@60288
  1243
from matches as well as term patterns within matches. The Isabelle
wenzelm@60288
  1244
documentation provides an entry "eisbach" for the Eisbach User Manual.
wenzelm@60288
  1245
Sources and various examples are in ~~/src/HOL/Eisbach/.

  1250
* Improved folding mode "isabelle" based on Isar syntax. Alternatively,
wenzelm@59569
  1251
the "sidekick" mode may be used for document structure.
wenzelm@59569
  1252
wenzelm@59569
  1253
* Extended bracket matching based on Isar language structure. System
wenzelm@59569
  1254
option jedit_structure_limit determines maximum number of lines to scan
wenzelm@59569
  1255
in the buffer.
wenzelm@58758
  1256
wenzelm@58540
  1257
* Support for BibTeX files: context menu, context-sensitive token
wenzelm@58540
  1258
marker, SideKick parser.
wenzelm@58524
  1259
wenzelm@58551
  1260
* Document antiquotation @{cite} provides formal markup, which is
wenzelm@60265
  1261
interpreted semi-formally based on .bib files that happen to be open in
wenzelm@60265
  1262
the editor (hyperlinks, completion etc.).
wenzelm@58551
  1263
wenzelm@58785
  1264
* Less waste of vertical space via negative line spacing (see Global
wenzelm@58785
  1265
Options / Text Area).
wenzelm@58785
  1266
wenzelm@60091
  1267
* Improved graphview panel with optional output of PNG or PDF, for
wenzelm@60273
  1268
display of 'thy_deps', 'class_deps' etc.
wenzelm@60010
  1269
wenzelm@60116
  1270
* The commands 'thy_deps' and 'class_deps' allow optional bounds to
wenzelm@60116
  1271
restrict the visualized hierarchy.
wenzelm@60095
  1272
wenzelm@60072
  1273
* Improved scheduling for asynchronous print commands (e.g. provers
wenzelm@60072

managed by the Sledgehammer panel) wrt. ongoing document processing.

*** Document preparation ***
wenzelm@59951
  1278
wenzelm@59951
  1279
* Document markup commands 'chapter', 'section', 'subsection',
wenzelm@59951
  1280
'subsubsection', 'text', 'txt', 'text_raw' work uniformly in any
wenzelm@59951
  1281
context, even before the initial 'theory' command. Obsolete proof
wenzelm@59951
  1282
commands 'sect', 'subsect', 'subsubsect', 'txt_raw' have been
wenzelm@59951
  1283
discontinued, use 'section', 'subsection', 'subsubsection', 'text_raw'
wenzelm@59951
  1284
instead. The old 'header' command is still retained for some time, but
wenzelm@59951
  1285
should be replaced by 'chapter', 'section' etc. (using "isabelle
wenzelm@59951
  1286
update_header"). Minor INCOMPATIBILITY.
wenzelm@59951
  1287
wenzelm@60010
  1288
* Official support for "tt" style variants, via \isatt{...} or
wenzelm@60010
  1289
\begin{isabellett}...\end{isabellett}. The somewhat fragile \verb or
wenzelm@60010
  1290
verbatim environment of LaTeX is no longer used. This allows @{ML} etc.
wenzelm@60010
  1291
as argument to other macros (such as footnotes).
wenzelm@60010
  1292
wenzelm@60010
  1293
* Document antiquotation @{verbatim} prints ASCII text literally in "tt"
wenzelm@60010
  1294
style.
wenzelm@60010
  1295
wenzelm@60010
  1296
* Discontinued obsolete option "document_graph": session_graph.pdf is
wenzelm@60010
  1297
produced unconditionally for HTML browser_info and PDF-LaTeX document.
wenzelm@60010
  1298
wenzelm@59951
  1299
* Diagnostic commands and document markup commands within a proof do not
wenzelm@59951
  1300
affect the command tag for output. Thus commands like 'thm' are subject
wenzelm@59951
  1301
to proof document structure, and no longer "stick out" accidentally.
wenzelm@59951
  1302
Commands 'text' and 'txt' merely differ in the LaTeX style, not their
wenzelm@59951
  1303
tags. Potential INCOMPATIBILITY in exotic situations.
wenzelm@59951
  1304
wenzelm@59951
  1305
* System option "pretty_margin" is superseded by "thy_output_margin",
wenzelm@59951
  1306
which is also accessible via document antiquotation option "margin".
wenzelm@59951
  1307
Only the margin for document output may be changed, but not the global
wenzelm@59951
  1308
pretty printing: that is 76 for plain console output, and adapted
wenzelm@59951
  1309
dynamically in GUI front-ends. Implementations of document
wenzelm@59951
  1310
antiquotations need to observe the margin explicitly according to
wenzelm@59951
  1311
Thy_Output.string_of_margin. Minor INCOMPATIBILITY.
wenzelm@59951
  1312
wenzelm@60299
  1313
* Specification of 'document_files' in the session ROOT file is
wenzelm@60299
  1314
mandatory for document preparation. The legacy mode with implicit
wenzelm@60299
  1315
copying of the document/ directory is no longer supported. Minor

  1320
wenzelm@59835
  1321
* Proof methods with explicit instantiation ("rule_tac", "subgoal_tac"
wenzelm@59835
  1322
etc.) allow an optional context of local variables ('for' declaration):
wenzelm@59835
  1323
these variables become schematic in the instantiated theorem; this
wenzelm@59835
  1324
behaviour is analogous to 'for' in attributes "where" and "of".
wenzelm@59835
  1325
Configuration option rule_insts_schematic (default false) controls use
wenzelm@59835
  1326
of schematic variables outside the context. Minor INCOMPATIBILITY,
wenzelm@59835
  1327
declare rule_insts_schematic = true temporarily and update to use local
wenzelm@59835
  1328
variable declarations or dummy patterns instead.
wenzelm@59835
  1329
wenzelm@60010
  1330
* Explicit instantiation via attributes "where", "of", and proof methods
wenzelm@60010
  1331
"rule_tac" with derivatives like "subgoal_tac" etc. admit dummy patterns
wenzelm@60010
  1332
("_") that stand for anonymous local variables.
wenzelm@60010
  1333
wenzelm@59951
  1334
* Generated schematic variables in standard format of exported facts are
wenzelm@59951
  1335
incremented to avoid material in the proof context. Rare
wenzelm@59951
  1336
INCOMPATIBILITY, explicit instantiation sometimes needs to refer to

* Lexical separation of signed and unsigned numerals: categories "num"
wenzelm@60011
  1340
and "float" are unsigned. INCOMPATIBILITY: subtle change in precedence
wenzelm@60011
  1341

like "(- 1) ^ n".

* New (co)datatype package:
blanchet@58374
  1352
  - The 'datatype_new' command has been renamed 'datatype'. The old
blanchet@58374
  1353
    command of that name is now called 'old_datatype' and is provided
blanchet@58374
  1354
    by "~~/src/HOL/Library/Old_Datatype.thy". See

  1372
  - The "no_code" option to "free_constructors", "datatype_new", and
blanchet@58192

    INCOMPATIBILITY.
blanchet@58044
  1375
  - The rules "set_empty" have been removed. They are easy

    consequences of other set rules "by auto".
blanchet@58044
  1377

blanchet@58044
  1378
  - The rule "set_cases" is now registered with the "[cases set]"
blanchet@57990

blanchet@57990
  1380
    method when more than one case rule is applicable (e.g., an
blanchet@57990
  1381
    assumption is of the form "w : set ws" and the method "cases w"
blanchet@57990
  1382
    is invoked). The solution is to specify the case rule explicitly
blanchet@57990

wenzelm@60115
  1395
    Lifting_Product and Lifting_Option from Main became obsolete and
wenzelm@60115
  1396
    were removed. Changed definitions of the relators rel_prod and
wenzelm@60115
  1397
    rel_sum (using inductive).
traytel@60112
  1398
    INCOMPATIBILITY: use rel_prod.simps and rel_sum.simps instead
wenzelm@60115

wenzelm@60115
  1400
    Minor INCOMPATIBILITY: (rarely used by name) transfer theorem names
wenzelm@60115

  - Parametricity theorems for map functions, relators, set functions,
wenzelm@60261
  1403
    constructors, case combinators, discriminators, selectors and
wenzelm@60261
  1404

  1408
  - The old 'datatype' command has been renamed 'old_datatype', and
blanchet@58374
  1409
    'rep_datatype' has been renamed 'old_rep_datatype'. They are

blanchet@57983
  1419
blanchet@59039
  1420
* Nitpick:
wenzelm@60011
  1421
  - Fixed soundness bug related to the strict and non-strict subset
blanchet@59039
  1422
    operations.
blanchet@59039
  1423
blanchet@57737
  1424
* Sledgehammer:
blanchet@59511
  1425
  - CVC4 is now included with Isabelle instead of CVC3 and run by
blanchet@59511
  1426
    default.
blanchet@59965
  1427
  - Z3 is now always enabled by default, now that it is fully open
blanchet@59965
  1428
    source. The "z3_non_commercial" option is discontinued.
blanchet@57737
  1429
  - Minimization is now always enabled by default.
wenzelm@60011
  1430
    Removed sub-command:
blanchet@57737
  1431
      min
blanchet@59967
  1432
  - Proof reconstruction, both one-liners and Isar, has been
blanchet@59039
  1433
    dramatically improved.
blanchet@59039
  1434
  - Improved support for CVC4 and veriT.
blanchet@57737
  1435
blanchet@58062
  1436
* Old and new SMT modules:
blanchet@58067
  1437
  - The old 'smt' method has been renamed 'old_smt' and moved to
wenzelm@59569
  1438
    'src/HOL/Library/Old_SMT.thy'. It is provided for compatibility,
wenzelm@59569
  1439
    until applications have been ported to use the new 'smt' method. For
wenzelm@59569
  1440
    the method to work, an older version of Z3 (e.g. Z3 3.2 or 4.0) must
wenzelm@59569
  1441
    be installed, and the environment variable "OLD_Z3_SOLVER" must
wenzelm@59569
  1442
    point to it.
blanchet@58062
  1443
    INCOMPATIBILITY.
blanchet@58067

  - The 'smt2' method has been renamed 'smt'.
blanchet@58060
  1445
    INCOMPATIBILITY.
wenzelm@59569
  1446
  - New option 'smt_reconstruction_step_timeout' to limit the

  1447
    reconstruction time of Z3 proof steps in the new 'smt' method.
boehmes@59216
  1448
  - New option 'smt_statistics' to display statistics of the new 'smt'
boehmes@59216
  1449
    method, especially runtime statistics of Z3 proof reconstruction.
blanchet@58060
  1450
wenzelm@60261
  1451
* Lifting: command 'lift_definition' allows to execute lifted constants
wenzelm@60261
  1452
that have as a return type a datatype containing a subtype. This
wenzelm@60261
  1453
overcomes long-time limitations in the area of code generation and
wenzelm@60261
  1454
lifting, and avoids tedious workarounds.
kuncar@60258
  1455
wenzelm@60010
  1456
* Command and antiquotation "value" provide different evaluation slots
wenzelm@60010
  1457
(again), where the previous strategy (NBE after ML) serves as default.
wenzelm@60010
  1458
Minor INCOMPATIBILITY.
wenzelm@60010
  1459
wenzelm@60010
  1460
* Add NO_MATCH-simproc, allows to check for syntactic non-equality.
wenzelm@60010
  1461
wenzelm@60010
  1462
* field_simps: Use NO_MATCH-simproc for distribution rules, to avoid
wenzelm@60010
  1463
non-termination in case of distributing a division. With this change
wenzelm@60010
  1464
field_simps is in some cases slightly less powerful, if it fails try to
wenzelm@60010
  1465
add algebra_simps, or use divide_simps. Minor INCOMPATIBILITY.
wenzelm@60010
  1466
wenzelm@60010
  1467
* Separate class no_zero_divisors has been given up in favour of fully
wenzelm@60010
  1468
algebraic semiring_no_zero_divisors. INCOMPATIBILITY.
wenzelm@60010
  1469
wenzelm@60010
  1470
* Class linordered_semidom really requires no zero divisors.
wenzelm@60010
  1471
INCOMPATIBILITY.
wenzelm@60010
  1472
wenzelm@60010
  1473
* Classes division_ring, field and linordered_field always demand
wenzelm@60010
  1474
"inverse 0 = 0". Given up separate classes division_ring_inverse_zero,
wenzelm@60010
  1475
field_inverse_zero and linordered_field_inverse_zero. INCOMPATIBILITY.
wenzelm@60010
  1476
wenzelm@60010
  1477
* Classes cancel_ab_semigroup_add / cancel_monoid_add specify explicit
wenzelm@60010
  1478
additive inverse operation. INCOMPATIBILITY.
wenzelm@60010
  1479
lp15@60020
  1480
* Complex powers and square roots. The functions "ln" and "powr" are now
wenzelm@60025
  1481
overloaded for types real and complex, and 0 powr y = 0 by definition.
wenzelm@60025
  1482
INCOMPATIBILITY: type constraints may be necessary.
lp15@60020
  1483
wenzelm@60010
  1484
* The functions "sin" and "cos" are now defined for any type of sort
wenzelm@60010
  1485
"{real_normed_algebra_1,banach}" type, so in particular on "real" and
wenzelm@60010
  1486
"complex" uniformly. Minor INCOMPATIBILITY: type constraints may be
wenzelm@60010
  1487
needed.
wenzelm@60010
  1488
wenzelm@60010
  1489
* New library of properties of the complex transcendental functions sin,
wenzelm@60010
  1490
cos, tan, exp, Ln, Arctan, Arcsin, Arccos. Ported from HOL Light.
wenzelm@60010
  1491
wenzelm@60010
  1492
* The factorial function, "fact", now has type "nat => 'a" (of a sort
wenzelm@60010
  1493
that admits numeric types including nat, int, real and complex.
wenzelm@60010
  1494
INCOMPATIBILITY: an expression such as "fact 3 = 6" may require a type
wenzelm@60010
  1495
constraint, and the combination "real (fact k)" is likely to be
wenzelm@60010
  1496
unsatisfactory. If a type conversion is still necessary, then use
wenzelm@60010
  1497
"of_nat (fact k)" or "real_of_nat (fact k)".
wenzelm@60010
  1498
wenzelm@60010
  1499
* Removed functions "natfloor" and "natceiling", use "nat o floor" and
wenzelm@60010
  1500
"nat o ceiling" instead. A few of the lemmas have been retained and
wenzelm@60010
  1501
adapted: in their names "natfloor"/"natceiling" has been replaced by
wenzelm@60010
  1502
"nat_floor"/"nat_ceiling".
wenzelm@60010
  1503
wenzelm@60010
  1504
* Qualified some duplicated fact names required for boostrapping the
wenzelm@60010
  1505
type class hierarchy:
wenzelm@60010
  1506
  ab_add_uminus_conv_diff ~> diff_conv_add_uminus
wenzelm@60010
  1507
  field_inverse_zero ~> inverse_zero
wenzelm@60010
  1508
  field_divide_inverse ~> divide_inverse
wenzelm@60010
  1509
  field_inverse ~> left_inverse
wenzelm@60010
  1510
Minor INCOMPATIBILITY.
wenzelm@60010
  1511
wenzelm@60010
  1512
* Eliminated fact duplicates:
wenzelm@60010
  1513
  mult_less_imp_less_right ~> mult_right_less_imp_less
wenzelm@60010
  1514
  mult_less_imp_less_left ~> mult_left_less_imp_less
wenzelm@60010
  1515
Minor INCOMPATIBILITY.
wenzelm@60010
  1516
wenzelm@60010
  1517
* Fact consolidation: even_less_0_iff is subsumed by
wenzelm@60010
  1518
double_add_less_zero_iff_single_add_less_zero (simp by default anyway).
wenzelm@60010
  1519
wenzelm@60010
  1520
* Generalized and consolidated some theorems concerning divsibility:
wenzelm@60010
  1521
  dvd_reduce ~> dvd_add_triv_right_iff
wenzelm@60010
  1522
  dvd_plus_eq_right ~> dvd_add_right_iff
wenzelm@60010
  1523
  dvd_plus_eq_left ~> dvd_add_left_iff
wenzelm@60010
  1524
Minor INCOMPATIBILITY.
wenzelm@60010

wenzelm@60010
  1526
* "even" and "odd" are mere abbreviations for "2 dvd _" and "~ 2 dvd _"
wenzelm@60010
  1527
and part of theory Main.
wenzelm@60010
  1528
  even_def ~> even_iff_mod_2_eq_zero
wenzelm@60010
  1529
INCOMPATIBILITY.
wenzelm@60010
  1530
wenzelm@60010
  1531

wenzelm@60010
  1532
INCOMPATIBILITY.
wenzelm@60010
  1533
wenzelm@60010
  1534
* Bootstrap of listsum as special case of abstract product over lists.
wenzelm@60010
  1535
Fact rename:
wenzelm@60010
  1536
    listsum_def ~> listsum.eq_foldr
wenzelm@60010
  1537
INCOMPATIBILITY.
wenzelm@60010
  1538
wenzelm@60010
  1539
* Product over lists via constant "listprod".
wenzelm@60010
  1540
wenzelm@60010
  1541
* Theory List: renamed drop_Suc_conv_tl and nth_drop' to

  1542
Cons_nth_drop_Suc.
nipkow@58247

wenzelm@59569
  1545
generated code in target languages in HOL/Library/Code_Test. See
wenzelm@59569
  1546

  1547
wenzelm@60010
  1548
* Library/Multiset:
blanchet@59813
  1549
  - Introduced "replicate_mset" operation.
blanchet@59813
  1550
  - Introduced alternative characterizations of the multiset ordering in
blanchet@59813
  1551
    "Library/Multiset_Order".
blanchet@59958
  1552

      <#, \<subset># abbreviate < (strict subset)
blanchet@59986
  1560
      <=#, \<le>#, \<subseteq># abbreviate <= (subset or equal)
blanchet@59986

    INCOMPATIBILITY.
blanchet@59813

wenzelm@60010
  1580
use local CSDP executable, which is much faster than the NEOS server.
wenzelm@60010
  1581
The "sos_cert" functionality is invoked as "sos" with additional

wenzelm@60010
  1586
hardware floating point arithmetic to randomly discover potential

  1603
* Subtle change of name space policy: undeclared entries are now
wenzelm@60010
  1604
considered inaccessible, instead of accessible via the fully-qualified
wenzelm@60010
  1605
internal name. This mainly affects Name_Space.intern (and derivatives),
wenzelm@60010
  1606
which may produce an unexpected Long_Name.hidden prefix. Note that
wenzelm@60011
  1607
contemporary applications use the strict Name_Space.check (and
wenzelm@60010
  1608
derivatives) instead, which is not affected by the change. Potential
wenzelm@60010
  1609
INCOMPATIBILITY in rare applications of Name_Space.intern.
wenzelm@59951

ERROR instead of internal Toplevel.UNDEF.
wenzelm@60096
  1613
wenzelm@59951
  1614
* Basic combinators map, fold, fold_map, split_list, apply are available
wenzelm@59951
  1615
as parameterized antiquotations, e.g. @{map 4} for lists of quadruples.
wenzelm@59951
  1616
wenzelm@59951
  1617
* Renamed "pairself" to "apply2", in accordance to @{apply 2}.
wenzelm@59951
  1618
INCOMPATIBILITY.
wenzelm@59951
  1619
wenzelm@59951
  1620
* Former combinators NAMED_CRITICAL and CRITICAL for central critical
wenzelm@59951
  1621
sections have been discontinued, in favour of the more elementary
wenzelm@59951
  1622
Multithreading.synchronized and its high-level derivative
wenzelm@59951
  1623
Synchronized.var (which is usually sufficient in applications). Subtle
wenzelm@59951
  1624
INCOMPATIBILITY: synchronized access needs to be atomic and cannot be
wenzelm@59951
  1625
nested.
wenzelm@59951
  1626
wenzelm@60010
  1627
* Synchronized.value (ML) is actually synchronized (as in Scala): subtle
wenzelm@60010
  1628
change of semantics with minimal potential for INCOMPATIBILITY.
wenzelm@59899
  1629
wenzelm@59621
  1630
* The main operations to certify logical entities are Thm.ctyp_of and
wenzelm@59621
  1631
Thm.cterm_of with a local context; old-style global theory variants are
wenzelm@59621
  1632
available as Thm.global_ctyp_of and Thm.global_cterm_of.
wenzelm@59621
  1633
INCOMPATIBILITY.
wenzelm@59621

wenzelm@59582
  1638
wenzelm@58963

resolve_tac, eresolve_tac, dresolve_tac, forward_tac, match_tac,
wenzelm@59498

blanchet@58066
  1644
PARALLEL_GOALS.
blanchet@58066
  1645
wenzelm@59564
  1646
* Goal.prove_multi is superseded by the fully general Goal.prove_common,
wenzelm@59564
  1647
which also allows to specify a fork priority.
wenzelm@59564
  1648
wenzelm@59936
  1649
* Antiquotation @{command_spec "COMMAND"} is superseded by
wenzelm@59936

cartouches instead of old-style {* verbatim *} or `alt_string` tokens.
wenzelm@59951
  1661

* Discontinued old-fashioned "codegen" tool. Code generation can always
wenzelm@59951
  1665
be externally triggered using an appropriate ROOT file plus a
wenzelm@59951
  1666
corresponding theory. Parametrization is possible using environment

wenzelm@57452
  1687
* Support for official Standard ML within the Isabelle context.
wenzelm@57452
  1688
Command 'SML_file' reads and evaluates the given Standard ML file.
wenzelm@57452
  1689
Toplevel bindings are stored within the theory context; the initial
wenzelm@57452
  1690
environment is restricted to the Standard ML implementation of
wenzelm@57452
  1691
Poly/ML, without the add-ons of Isabelle/ML.  Commands 'SML_import'
wenzelm@57452
  1692
and 'SML_export' allow to exchange toplevel bindings between the two
wenzelm@57452
  1693
separate environments.  See also ~~/src/Tools/SML/Examples.thy for
wenzelm@57452
  1694
some examples.
wenzelm@56499
  1695
wenzelm@57504
  1696
* Standard tactics and proof methods such as "clarsimp", "auto" and
wenzelm@57504
  1697
"safe" now preserve equality hypotheses "x = expr" where x is a free
wenzelm@57504
  1698
variable.  Locale assumptions and chained facts containing "x"
wenzelm@57504
  1699
continue to be useful.  The new method "hypsubst_thin" and the
wenzelm@57504
  1700
configuration option "hypsubst_thin" (within the attribute name space)
wenzelm@57504
  1701
restore the previous behavior.  INCOMPATIBILITY, especially where
wenzelm@57504
  1702
induction is done after these methods or when the names of free and
wenzelm@57504
  1703
bound variables clash.  As first approximation, old proofs may be
wenzelm@57504
  1704
repaired by "using [[hypsubst_thin = true]]" in the critical spot.
wenzelm@57504
  1705
wenzelm@56232
  1706
* More static checking of proof methods, which allows the system to
wenzelm@56232
  1707
form a closure over the concrete syntax.  Method arguments should be
wenzelm@56232
  1708
processed in the original proof context as far as possible, before
wenzelm@56232
  1709
operating on the goal state.  In any case, the standard discipline for
wenzelm@56232
  1710
subgoal-addressing needs to be observed: no subgoals or a subgoal
wenzelm@56232
  1711
number that is out of range produces an empty result sequence, not an
wenzelm@56232
  1712
exception.  Potential INCOMPATIBILITY for non-conformant tactical
wenzelm@56232
  1713
proof tools.
wenzelm@56232
  1714
wenzelm@57452
  1715
* Lexical syntax (inner and outer) supports text cartouches with
wenzelm@57452
  1716
arbitrary nesting, and without escapes of quotes etc.  The Prover IDE
wenzelm@57452
  1717
supports input via ` (backquote).
wenzelm@57452
  1718
wenzelm@57452
  1719
* The outer syntax categories "text" (for formal comments and document
wenzelm@57452
  1720
markup commands) and "altstring" (for literal fact references) allow
wenzelm@57452
  1721
cartouches as well, in addition to the traditional mix of quotations.
wenzelm@57452
  1722
wenzelm@57452
  1723
* Syntax of document antiquotation @{rail} now uses \<newline> instead
wenzelm@57452
  1724
of "\\", to avoid the optical illusion of escaped backslash within
wenzelm@57491
  1725
string token.  General renovation of its syntax using text cartouches.
wenzelm@57452
  1726
Minor INCOMPATIBILITY.
wenzelm@57452
  1727
wenzelm@57452
  1728
* Discontinued legacy_isub_isup, which was a temporary workaround for
wenzelm@57452
  1729
Isabelle/ML in Isabelle2013-1.  The prover process no longer accepts
wenzelm@57452
  1730
old identifier syntax with \<^isub> or \<^isup>.  Potential
wenzelm@57452
  1731
INCOMPATIBILITY.
wenzelm@57452
  1732
wenzelm@57452
  1733
* Document antiquotation @{url} produces markup for the given URL,
wenzelm@57452
  1734
which results in an active hyperlink within the text.
wenzelm@57452
  1735
wenzelm@57452
  1736
* Document antiquotation @{file_unchecked} is like @{file}, but does
wenzelm@57452
  1737
not check existence within the file-system.
wenzelm@57452
  1738
wenzelm@57452
  1739
* Updated and extended manuals: codegen, datatypes, implementation,
wenzelm@57452

wenzelm@57452
  1750
to PIDE hyperlinks.
wenzelm@57452
  1751
wenzelm@57452
  1752
* Auxiliary files ('ML_file' etc.) are managed by the Prover IDE.
wenzelm@57452
  1753
Open text buffers take precedence over copies within the file-system.
wenzelm@57452
  1754
wenzelm@57452
  1755
* Improved support for Isabelle/ML, with jEdit mode "isabelle-ml" for
wenzelm@57452
  1756
auxiliary ML files.
wenzelm@57423
  1757
wenzelm@57423
  1758
* Improved syntactic and semantic completion mechanism, with simple
wenzelm@57423
  1759
templates, completion language context, name-space completion,
wenzelm@57423
  1760
file-name completion, spell-checker completion.
wenzelm@57423
  1761
wenzelm@57423
  1762
* Refined GUI popup for completion: more robust key/mouse event
wenzelm@57423
  1763
handling and propagation to enclosing text area -- avoid loosing
wenzelm@57423
  1764
keystrokes with slow / remote graphics displays.
wenzelm@57423
  1765
wenzelm@57833
  1766
* Completion popup supports both ENTER and TAB (default) to select an
wenzelm@57833
  1767
item, depending on Isabelle options.
wenzelm@57833
  1768
wenzelm@57423
  1769
* Refined insertion of completion items wrt. jEdit text: multiple
wenzelm@57423
  1770
selections, rectangular selections, rectangular selection as "tall
wenzelm@57423
  1771
caret".
wenzelm@56342
  1772
wenzelm@56580
  1773
* Integrated spell-checker for document text, comments etc. with
wenzelm@57423
  1774
completion popup and context-menu.
wenzelm@56554
  1775
wenzelm@56879
  1776
* More general "Query" panel supersedes "Find" panel, with GUI access
wenzelm@56879
  1777
to commands 'find_theorems' and 'find_consts', as well as print
wenzelm@56879
  1778
operations for the context.  Minor incompatibility in keyboard
wenzelm@56879
  1779
shortcuts etc.: replace action isabelle-find by isabelle-query.
wenzelm@56761
  1780
wenzelm@56901
  1781
* Search field for all output panels ("Output", "Query", "Info" etc.)
wenzelm@56901
  1782
to highlight text via regular expression.
wenzelm@56901
  1783
wenzelm@54881
  1784
* Option "jedit_print_mode" (see also "Plugin Options / Isabelle /
wenzelm@54881
  1785
General") allows to specify additional print modes for the prover
wenzelm@54881
  1786
process, without requiring old-fashioned command-line invocation of
wenzelm@54881
  1787
"isabelle jedit -m MODE".
wenzelm@54881
  1788
wenzelm@56505
  1789
* More support for remote files (e.g. http) using standard Java
wenzelm@56505
  1790
networking operations instead of jEdit virtual file-systems.
wenzelm@56505
  1791
wenzelm@57822
  1792
* Empty editors buffers that are no longer required (e.g.\ via theory
wenzelm@57822
  1793
imports) are automatically removed from the document model.
wenzelm@57822
  1794
wenzelm@57869
  1795
* Improved monitor panel.
wenzelm@57869
  1796
wenzelm@56838
  1797
* Improved Console/Scala plugin: more uniform scala.Console output,
wenzelm@56838
  1798
more robust treatment of threads and interrupts.
wenzelm@56838
  1799
wenzelm@56939
  1800
* Improved management of dockable windows: clarified keyboard focus
wenzelm@56939
  1801
and window placement wrt. main editor view; optional menu item to
wenzelm@56939
  1802
"Detach" a copy where this makes sense.
wenzelm@56939
  1803
wenzelm@57452
  1804
* New Simplifier Trace panel provides an interactive view of the
wenzelm@57594
  1805
simplification process, enabled by the "simp_trace_new" attribute
wenzelm@57452
  1806

* Low-level type-class commands 'classes', 'classrel', 'arities' have
wenzelm@57504
  1812
been discontinued to avoid the danger of non-trivial axiomatization
wenzelm@57504
  1813
that is not immediately visible.  INCOMPATIBILITY, use regular
wenzelm@57504
  1814
'instance' command with proof.  The required OFCLASS(...) theorem
wenzelm@57504
  1815
might be postulated via 'axiomatization' beforehand, or the proof
wenzelm@57504
  1816
finished trivially if the underlying class definition is made vacuous
wenzelm@57504
  1817
(without any assumptions).  See also Isabelle/ML operations

  1818
Axclass.class_axiomatization, Axclass.classrel_axiomatization,

* Basic constants of Pure use more conventional names and are always
wenzelm@56245
  1822
qualified.  Rare INCOMPATIBILITY, but with potentially serious
wenzelm@56245
  1823
consequences, notably for tools in Isabelle/ML.  The following
wenzelm@56245
  1824
renaming needs to be applied:
wenzelm@56245
  1825
wenzelm@56245
  1826
  ==             ~>  Pure.eq
wenzelm@56245
  1827
  ==>            ~>  Pure.imp
wenzelm@56245
  1828
  all            ~>  Pure.all
wenzelm@56245
  1829
  TYPE           ~>  Pure.type
wenzelm@56245
  1830
  dummy_pattern  ~>  Pure.dummy_pattern
wenzelm@56245
  1831
wenzelm@56245
  1832
Systematic porting works by using the following theory setup on a
wenzelm@56245
  1833
*previous* Isabelle version to introduce the new name accesses for the
wenzelm@56245
  1834
old constants:
wenzelm@56245
  1835
wenzelm@56245
  1836
setup {*
wenzelm@56245
  1837
  fn thy => thy
wenzelm@56245
  1838
    |> Sign.root_path
wenzelm@56245
  1839
    |> Sign.const_alias (Binding.qualify true "Pure" @{binding eq}) "=="
wenzelm@56245
  1840
    |> Sign.const_alias (Binding.qualify true "Pure" @{binding imp}) "==>"
wenzelm@56245
  1841
    |> Sign.const_alias (Binding.qualify true "Pure" @{binding all}) "all"
wenzelm@56245
  1842
    |> Sign.restore_naming thy
wenzelm@56245
  1843
*}
wenzelm@56245
  1844
wenzelm@56245
  1845
Thus ML antiquotations like @{const_name Pure.eq} may be used already.
wenzelm@56245
  1846
Later the application is moved to the current Isabelle version, and
wenzelm@56245
  1847
the auxiliary aliases are deleted.
wenzelm@56245
  1848
wenzelm@55143
  1849
* Attributes "where" and "of" allow an optional context of local
wenzelm@55143
  1850
variables ('for' declaration): these variables become schematic in the
wenzelm@55143
  1851
instantiated theorem.
wenzelm@55143
  1852
wenzelm@55152
  1853
* Obsolete attribute "standard" has been discontinued (legacy since
wenzelm@55152
  1854
Isabelle2012).  Potential INCOMPATIBILITY, use explicit 'for' context
wenzelm@55152
  1855
where instantiations with schematic variables are intended (for
wenzelm@55152
  1856
declaration commands like 'lemmas' or attributes like "of").  The
wenzelm@55152
  1857
following temporary definition may help to port old applications:
wenzelm@55152
  1858
wenzelm@55152
  1859
  attribute_setup standard =
wenzelm@55152
  1860
    "Scan.succeed (Thm.rule_attribute (K Drule.export_without_context))"
wenzelm@55152
  1861
wenzelm@55001
  1862
* More thorough check of proof context for goal statements and
wenzelm@55006
  1863
attributed fact expressions (concerning background theory, declared
wenzelm@55006
  1864
hyps).  Potential INCOMPATIBILITY, tools need to observe standard
wenzelm@55006
  1865
context discipline.  See also Assumption.add_assumes and the more
wenzelm@55006
  1866
primitive Thm.assume_hyps.

wenzelm@57508
  2070
* New internal SAT solver "cdclite" that produces models and proof
wenzelm@57508
  2071
traces.  This solver replaces the internal SAT solvers "enumerate" and
wenzelm@57508
  2072
"dpll".  Applications that explicitly used one of these two SAT
wenzelm@57508
  2073
solvers should use "cdclite" instead. In addition, "cdclite" is now
wenzelm@57508
  2074
the default SAT solver for the "sat" and "satx" proof methods and
wenzelm@57508
  2075
corresponding tactics; the old default can be restored using "declare

wenzelm@57508
  2079
"SMT2", uses SMT-LIB 2 and supports recent versions of Z3 (e.g.,
wenzelm@57508
  2080
4.3). The new proof method is called "smt2". CVC3 and CVC4 are also
wenzelm@57508
  2081
supported as oracles. Yices is no longer supported, because no version
wenzelm@57508
  2082
of the solver can handle both SMT-LIB 2 and quantifiers.
wenzelm@57508
  2083
wenzelm@57508
  2084
* Activation of Z3 now works via "z3_non_commercial" system option
wenzelm@57508

blanchet@57532
  2092
    . New SML-based learning algorithms eliminate the dependency on
wenzelm@57508
  2093
      Python and increase performance and reliability.
wenzelm@57508
  2094
    . MaSh and MeSh are now used by default together with the
wenzelm@57508
  2095
      traditional MePo (Meng-Paulson) relevance filter. To disable
wenzelm@57508
  2096
      MaSh, set the "MaSh" system option in Isabelle/jEdit Plugin
wenzelm@57508
  2097
      Options / Isabelle / General to "none".
wenzelm@57508

  2107
wenzelm@57508
  2108
* Nitpick:
wenzelm@57508
  2109
  - Fixed soundness bug whereby mutually recursive datatypes could
wenzelm@57508
  2110
    take infinite values.
wenzelm@57508
  2111
  - Fixed soundness bug with low-level number functions such as
wenzelm@57508
  2112
    "Abs_Integ" and "Rep_Integ".
wenzelm@57508
  2113
  - Removed "std" option.
wenzelm@57508
  2114
  - Renamed "show_datatypes" to "show_types" and "hide_datatypes" to

  2115
    "hide_types".
wenzelm@57508
  2116
wenzelm@57508

  2121
wenzelm@57508
  2122
* Adjustion of INF and SUP operations:
wenzelm@57508
  2123
  - Elongated constants INFI and SUPR to INFIMUM and SUPREMUM.
wenzelm@57508

* The signature and semantics of Document.Snapshot.cumulate_markup /
wenzelm@55622
  2664
select_markup have been clarified.  Markup is now traversed in the
wenzelm@55622
  2665
order of reports given by the prover: later markup is usually more
wenzelm@55622
  2666
specific and may override results accumulated so far.  The elements
wenzelm@55622
  2667
guard is mandatory and checked precisely.  Subtle INCOMPATIBILITY.

* Subtle change of semantics of Thm.eq_thm: theory stamps are not
wenzelm@57504
  2676
compared (according to Thm.thm_ord), but assumed to be covered by the
wenzelm@57504
  2677
current background theory.  Thus equivalent data produced in different
wenzelm@57504
  2678
branches of the theory graph usually coincides (e.g. relevant for
wenzelm@57504
  2679
theory merge).  Note that the softer Thm.eq_thm_prop is often more
wenzelm@57504
  2680
appropriate than Thm.eq_thm.

* Proper context for basic Simplifier operations: rewrite_rule,
wenzelm@57504
  2683
rewrite_goals_rule, rewrite_goals_tac etc. INCOMPATIBILITY, need to
wenzelm@57504
  2684
pass runtime Proof.context (and ensure that the simplified entity
wenzelm@57504
  2685
actually belongs to it).
wenzelm@57504
  2686
wenzelm@57504
  2687
* Proper context discipline for read_instantiate and instantiate_tac:
wenzelm@57504
  2688
variables that are meant to become schematic need to be given as
wenzelm@57504
  2689
fixed, and are generalized by the explicit context of local variables.
wenzelm@57504
  2690
This corresponds to Isar attributes "where" and "of" with 'for'
wenzelm@57504
  2691
declaration.  INCOMPATIBILITY, also due to potential change of indices
wenzelm@57504
  2692
of schematic variables.

wenzelm@56279
  2697
* Discontinued old Toplevel.debug in favour of system option
wenzelm@57452
  2698
"ML_exception_trace", which may be also declared within the context
wenzelm@57452

wenzelm@56281

* Configuration option "ML_print_depth" controls the pretty-printing
wenzelm@56281
  2705
depth of the ML compiler within the context.  The old print_depth in
wenzelm@56285
  2706
ML is still available as default_print_depth, but rarely used.  Minor
wenzelm@56285
  2707
INCOMPATIBILITY.

* Toplevel function "use" refers to raw ML bootstrap environment,
wenzelm@54449
  2710
without Isar context nor antiquotations.  Potential INCOMPATIBILITY.
wenzelm@54449
  2711
Note that 'ML_file' is the canonical command to load ML files into the
