*** General ***
wenzelm@62440
    11
wenzelm@62440
    12
* New symbol \<circle>, e.g. for temporal operator.
wenzelm@62440
    13
wenzelm@62453
    14
* Old 'header' command is no longer supported (legacy since
wenzelm@62453
    15
Isabelle2015).

*** Isar ***
wenzelm@62312
    19
wenzelm@62312
    20
* Command '\<proof>' is an alias for 'sorry', with different
wenzelm@62312
    21
typesetting. E.g. to produce proof holes in examples and documentation.
wenzelm@62216

blanchet@62327
    24
*** HOL ***
blanchet@62327
    25
wenzelm@62522
    26
* New abbreviations for negated existence (but not bounded existence):
wenzelm@62522
    27
wenzelm@62522
    28
  \<nexists>x. P x \<equiv> \<not> (\<exists>x. P x)
wenzelm@62522
    29
  \<nexists>!x. P x \<equiv> \<not> (\<exists>!x. P x)
wenzelm@62522
    30
wenzelm@62521
    31
* The print mode "HOL" for ASCII syntax of binders "!", "?", "?!", "@"
wenzelm@62521
    32
has been removed for output. It is retained for input only, until it is
wenzelm@62521
    33
eliminated altogether.
wenzelm@62521
    34
blanchet@62327
    35
* (Co)datatype package:
traytel@62332
    36
  - the predicator :: ('a => bool) => 'a F => bool is now a first-class
traytel@62332
    37
    citizen in bounded natural functors
blanchet@62327
    38
  - "primrec" now allows nested calls through the predicator in addition
blanchet@62327
    39
    to the map function.
traytel@62332
    40
  - "bnf" automatically discharges reflexive proof obligations
traytel@62332
    41
    "bnf" outputs a slightly modified proof obligation expressing rel in
traytel@62332
    42
       terms of map and set
traytel@62332
    43
       (not giving a specification for rel makes this one reflexive)
traytel@62332
    44
    "bnf" outputs a new proof obligation expressing pred in terms of set
traytel@62332
    45
       (not giving a specification for pred makes this one reflexive)
traytel@62332
    46
    INCOMPATIBILITY: manual "bnf" declarations may need adjustment
blanchet@62335
    47
  - Renamed lemmas:
blanchet@62335
    48
      rel_prod_apply ~> rel_prod_inject
blanchet@62335
    49
      pred_prod_apply ~> pred_prod_inject
blanchet@62335
    50
    INCOMPATIBILITY.
blanchet@62327
    51
wenzelm@62407
    52
* Renamed split_if -> if_split and split_if_asm -> if_split_asm to
wenzelm@62407
    53
resemble the f.split naming convention, INCOMPATIBILITY.
nipkow@62396
    54
haftmann@62430
    55
* Multiset membership is now expressed using set_mset rather than count.
haftmann@62430
    56
ASCII infix syntax ":#" has been discontinued.
haftmann@62430
    57
haftmann@62430
    58
  - Expressions "count M a > 0" and similar simplify to membership
haftmann@62430
    59
    by default.
haftmann@62430
    60
haftmann@62430
    61
  - Converting between "count M a = 0" and non-membership happens using
haftmann@62430
    62
    equations count_eq_zero_iff and not_in_iff.
haftmann@62430
    63
haftmann@62430
    64
  - Rules count_inI and in_countE obtain facts of the form
haftmann@62430
    65
    "count M a = n" from membership.
haftmann@62430
    66
haftmann@62430
    67
  - Rules count_in_diffI and in_diff_countE obtain facts of the form
haftmann@62430
    68
    "count M a = n + count N a" from membership on difference sets.
haftmann@62430
    69
haftmann@62430
    70
INCOMPATIBILITY.
haftmann@62430
    71
haftmann@62343
    72
* Compound constants INFIMUM and SUPREMUM are mere abbreviations now.
haftmann@62343
    73
INCOMPATIBILITY.
haftmann@62343
    74
lp15@62408
    75
* More complex analysis including Cauchy's inequality, Liouville theorem,
lp15@62408
    76
open mapping theorem, maximum modulus principle, Schwarz Lemma.
lp15@62408
    77
haftmann@62358
    78
* "Gcd (f ` A)" and "Lcm (f ` A)" are printed with optional
haftmann@62358
    79
comprehension-like syntax analogously to "Inf (f ` A)" and "Sup (f ` A)".
haftmann@62358
    80
haftmann@62345
    81
* Class semiring_Lcd merged into semiring_Gcd.  INCOMPATIBILITY.
haftmann@62345
    82
hoelzl@62376
    83
* The type class ordered_comm_monoid_add is now called
hoelzl@62376
    84
ordered_cancel_comm_monoid_add. A new type class ordered_comm_monoid_add is
hoelzl@62376
    85
introduced as the combination of ordered_ab_semigroup_add + comm_monoid_add.
hoelzl@62376
    86
INCOMPATIBILITY.
hoelzl@62376
    87
hoelzl@62376
    88
* Introduced the type classes canonically_ordered_comm_monoid_add and dioid.
hoelzl@62376
    89
hoelzl@62376
    90
* Added topological_monoid
hoelzl@62376
    91
haftmann@62352
    92
* Library/Polynomial.thy contains also derivation of polynomials
haftmann@62352
    93
but not gcd/lcm on polynomials over fields.  This has been moved
haftmann@62352
    94
to a separate theory Library/Polynomial_GCD_euclidean.thy, to
haftmann@62352
    95
pave way for a possible future different type class instantiation
haftmann@62352
    96
for polynomials over factorial rings.  INCOMPATIBILITY.
haftmann@62352
    97
haftmann@62348
    98
* Dropped various legacy fact bindings, whose replacements are often
haftmann@62348
    99

haftmann@62347
   188
INCOMPATIBILITY.
haftmann@62347
   189
wenzelm@62479
   190
* Session HOL-NSA has been renamed to HOL-Nonstandard_Analysis.
wenzelm@62479
   191
blanchet@62327
   192
wenzelm@62498
   193
*** ML ***
wenzelm@62498
   194
wenzelm@62498
   195
* Option ML_exception_debugger controls detailed exception trace via the
wenzelm@62498
   196
Poly/ML debugger. Relevant ML modules need to be compiled beforehand
wenzelm@62498
   197
with ML_file_debug, or with ML_file and option ML_debugger enabled. Note
wenzelm@62498
   198
debugger information requires consirable time and space: main
wenzelm@62498
   199
Isabelle/HOL with full debugger support may need ML_system_64.
wenzelm@62498
   200
wenzelm@62514
   201
* Local_Theory.restore has been renamed to Local_Theory.reset to
wenzelm@62514
   202
emphasize its disruptive impact on the cumulative context, notably the
wenzelm@62514
   203
scope of 'private' or 'qualified' names. Note that Local_Theory.reset is
wenzelm@62514
   204
only appropriate when targets are managed, e.g. starting from a global
wenzelm@62514
   205
theory and returning to it. Regular definitional packages should use
wenzelm@62514
   206
balanced blocks of Local_Theory.open_target versus
wenzelm@62514
   207
Local_Theory.close_target instead. Rare INCOMPATIBILITY.
wenzelm@62514
   208
wenzelm@62519
   209
* Structure TimeLimit (originally from the SML/NJ library) has been
wenzelm@62519
   210
replaced by structure Timeout, with slightly different signature.
wenzelm@62519
   211
INCOMPATIBILITY.
wenzelm@62519
   212
wenzelm@62498
   213
wenzelm@62354
   214
*** System ***
wenzelm@62354
   215
wenzelm@62549
   216
* File.bash_string, File.bash_path etc. represent Isabelle/ML and
wenzelm@62549
   217
Isabelle/Scala strings authentically within GNU bash. This is useful to
wenzelm@62549
   218
produce robust shell scripts under program control, without worrying
wenzelm@62549
   219
about spaces or special characters. Note that user output works via
wenzelm@62549
   220
Path.print (ML) or Path.toString (Scala). INCOMPATIBILITY, the old (and
wenzelm@62549
   221
less versatile) operations File.shell_quote, File.shell_path etc. have
wenzelm@62549
   222
been discontinued.
wenzelm@62549
   223
wenzelm@62415
   224
* The Isabelle system environment always ensures that the main
wenzelm@62415
   225
executables are found within the PATH: isabelle, isabelle_process,
wenzelm@62415
   226
isabelle_scala_script.
wenzelm@62415
   227
wenzelm@62525
   228
* Command-line tool "isabelle_process" no longer supports writable heap
wenzelm@62475
   229
images. INCOMPATIBILITY in exotic situations where "isabelle build"
wenzelm@62475
   230
cannot be used: the structure ML_Heap provides operations to save the ML
wenzelm@62475
   231
heap under program control.
wenzelm@62475
   232
wenzelm@62525
   233
* Command-line tool "isabelle_process" supports ML evaluation of literal
wenzelm@62525
   234
expressions (option -e) or files (option -f). Errors lead to premature
wenzelm@62525
   235
exit of the ML process with return code 1.
wenzelm@62525
   236
wenzelm@62525
   237
* Command-line tool "isabelle console -r" helps to bootstrap
wenzelm@62525
   238
Isabelle/Pure interactively.
wenzelm@62525
   239
wenzelm@62451
   240
* The somewhat pointless command-line tool "isabelle yxml" has been
wenzelm@62451
   241
discontinued. INCOMPATIBILITY, use operations from the modules "XML" and
wenzelm@62451
   242
"YXML" in Isabelle/ML or Isabelle/Scala.
wenzelm@62451
   243
wenzelm@62501
   244
* SML/NJ and old versions of Poly/ML are no longer supported.
wenzelm@62354
   245
wenzelm@62354
   246
wenzelm@62031
   247
New in Isabelle2016 (February 2016)

wenzelm@61337
   250
*** General ***
wenzelm@61337
   251
wenzelm@62168
   252
* Eisbach is now based on Pure instead of HOL. Objects-logics may import
wenzelm@62168
   253
either the theory ~~/src/HOL/Eisbach/Eisbach (for HOL etc.) or
wenzelm@62168
   254
~~/src/HOL/Eisbach/Eisbach_Old_Appl_Syntax (for FOL, ZF etc.). Note that
wenzelm@62168
   255
the HOL-Eisbach session located in ~~/src/HOL/Eisbach/ contains further
wenzelm@62168
   256
examples that do require HOL.
wenzelm@62168
   257
wenzelm@62157
   258
* Better resource usage on all platforms (Linux, Windows, Mac OS X) for
wenzelm@62157
   259
both Isabelle/ML and Isabelle/Scala.  Slightly reduced heap space usage.
wenzelm@62157
   260
wenzelm@62017
   261
* Former "xsymbols" syntax with Isabelle symbols is used by default,
wenzelm@62017
   262
without any special print mode. Important ASCII replacement syntax
wenzelm@62017
   263
remains available under print mode "ASCII", but less important syntax
wenzelm@62017
   264
has been removed (see below).
wenzelm@62017
   265
wenzelm@62109
   266
* Support for more arrow symbols, with rendering in LaTeX and Isabelle
wenzelm@62109
   267
fonts: \<Lleftarrow> \<Rrightarrow> \<longlongleftarrow> \<longlongrightarrow> \<longlonglongleftarrow> \<longlonglongrightarrow>.
wenzelm@62017
   268
wenzelm@62108
   269
* Special notation \<struct> for the first implicit 'structure' in the
wenzelm@62108
   270
context has been discontinued. Rare INCOMPATIBILITY, use explicit
wenzelm@62108
   271
structure name instead, notably in indexed notation with block-subscript
wenzelm@62108
   272
(e.g. \<odot>\<^bsub>A\<^esub>).
wenzelm@62108
   273
wenzelm@62108
   274
* The glyph for \<diamond> in the IsabelleText font now corresponds better to its
wenzelm@62108
   275
counterpart \<box> as quantifier-like symbol. A small diamond is available as
wenzelm@62108
   276
\<diamondop>; the old symbol \<struct> loses this rendering and any special
wenzelm@62108
   277
meaning.
wenzelm@62108
   278
wenzelm@62017
   279
* Syntax for formal comments "-- text" now also supports the symbolic
wenzelm@62017
   280
form "\<comment> text". Command-line tool "isabelle update_cartouches -c" helps
wenzelm@62017
   281
to update old sources.
wenzelm@62017
   282
wenzelm@61337
   283
* Toplevel theorem statements have been simplified as follows:
wenzelm@61337
   284
wenzelm@61337
   285
  theorems             ~>  lemmas
wenzelm@61337
   286
  schematic_lemma      ~>  schematic_goal
wenzelm@61337
   287
  schematic_theorem    ~>  schematic_goal
wenzelm@61337
   288
  schematic_corollary  ~>  schematic_goal
wenzelm@61337
   289
wenzelm@61337
   290
Command-line tool "isabelle update_theorems" updates theory sources
wenzelm@61337
   291
accordingly.
wenzelm@61337
   292
wenzelm@61338
   293
* Toplevel theorem statement 'proposition' is another alias for
wenzelm@61338
   294
'theorem'.
wenzelm@61338
   295
wenzelm@62169
   296
* The old 'defs' command has been removed (legacy since Isabelle2014).
wenzelm@62169
   297
INCOMPATIBILITY, use regular 'definition' instead. Overloaded and/or
wenzelm@62169
   298
deferred definitions require a surrounding 'overloading' block.

*** Prover IDE -- Isabelle/Scala/jEdit ***
wenzelm@60610
   302
wenzelm@60986
   303
* IDE support for the source-level debugger of Poly/ML, to work with
wenzelm@62253
   304
Isabelle/ML and official Standard ML. Option "ML_debugger" and commands
wenzelm@62253
   305
'ML_file_debug', 'ML_file_no_debug', 'SML_file_debug',
wenzelm@62253
   306
'SML_file_no_debug' control compilation of sources with or without
wenzelm@62253
   307
debugging information. The Debugger panel allows to set breakpoints (via
wenzelm@62253
   308
context menu), step through stopped threads, evaluate local ML
wenzelm@62253
   309
expressions etc. At least one Debugger view needs to be active to have
wenzelm@62253
   310
any effect on the running ML program.
wenzelm@60984
   311
wenzelm@61803
   312
* The State panel manages explicit proof state output, with dynamic
wenzelm@61803
   313
auto-update according to cursor movement. Alternatively, the jEdit
wenzelm@61803
   314
action "isabelle.update-state" (shortcut S+ENTER) triggers manual
wenzelm@61803
   315
update.
wenzelm@61729
   316
wenzelm@61729
   317
* The Output panel no longer shows proof state output by default, to
wenzelm@61729
   318
avoid GUI overcrowding. INCOMPATIBILITY, use the State panel instead or
wenzelm@61729
   319
enable option "editor_output_state".
wenzelm@61215
   320
wenzelm@61803
   321
* The text overview column (status of errors, warnings etc.) is updated
wenzelm@61803
   322
asynchronously, leading to much better editor reactivity. Moreover, the
wenzelm@61803
   323
full document node content is taken into account. The width of the
wenzelm@61803
   324
column is scaled according to the main text area font, for improved
wenzelm@61803
   325
visibility.
wenzelm@61803
   326
wenzelm@61803
   327
* The main text area no longer changes its color hue in outdated
wenzelm@61803
   328
situations. The text overview column takes over the role to indicate
wenzelm@61803
   329
unfinished edits in the PIDE pipeline. This avoids flashing text display
wenzelm@61803
   330
due to ad-hoc updates by auxiliary GUI components, such as the State
wenzelm@61803
   331
panel.
wenzelm@61803
   332
wenzelm@62254
   333
* Slightly improved scheduling for urgent print tasks (e.g. command
wenzelm@62254
   334
state output, interactive queries) wrt. long-running background tasks.
wenzelm@62017
   335
wenzelm@62017
   336
* Completion of symbols via prefix of \<name> or \<^name> or \name is
wenzelm@62017
   337
always possible, independently of the language context. It is never
wenzelm@62017
   338
implicit: a popup will show up unconditionally.
wenzelm@62017
   339
wenzelm@62017
   340
* Additional abbreviations for syntactic completion may be specified in
wenzelm@62017
   341
$ISABELLE_HOME/etc/abbrevs and $ISABELLE_HOME_USER/etc/abbrevs, with
wenzelm@62017
   342
support for simple templates using ASCII 007 (bell) as placeholder.
wenzelm@62017
   343
wenzelm@62234
   344
* Symbols \<oplus>, \<Oplus>, \<otimes>, \<Otimes>, \<odot>, \<Odot>, \<ominus>, \<oslash> no longer provide abbreviations for
wenzelm@62234
   345
completion like "+o", "*o", ".o" etc. -- due to conflicts with other
wenzelm@62234
   346
ASCII syntax. INCOMPATIBILITY, use plain backslash-completion or define
wenzelm@62234
   347
suitable abbreviations in $ISABELLE_HOME_USER/etc/abbrevs.
wenzelm@62234
   348
wenzelm@61483
   349
* Action "isabelle-emph" (with keyboard shortcut C+e LEFT) controls
wenzelm@61483
   350
emphasized text style; the effect is visible in document output, not in
wenzelm@61483
   351
the editor.
wenzelm@61483
   352
wenzelm@61483
   353
* Action "isabelle-reset" now uses keyboard shortcut C+e BACK_SPACE,
wenzelm@61483
   354
instead of former C+e LEFT.
wenzelm@61483
   355
wenzelm@61512
   356
* The command-line tool "isabelle jedit" and the isabelle.Main
wenzelm@62027
   357
application wrapper treat the default $USER_HOME/Scratch.thy more
wenzelm@61512
   358
uniformly, and allow the dummy file argument ":" to open an empty buffer
wenzelm@61512
   359
instead.
wenzelm@61512
   360
wenzelm@62017
   361
* New command-line tool "isabelle jedit_client" allows to connect to an
wenzelm@62017
   362
already running Isabelle/jEdit process. This achieves the effect of
wenzelm@62017
   363
single-instance applications seen on common GUI desktops.
wenzelm@62017
   364
wenzelm@61529
   365
* The default look-and-feel for Linux is the traditional "Metal", which
wenzelm@61529
   366
works better with GUI scaling for very high-resolution displays (e.g.
wenzelm@61529
   367
4K). Moreover, it is generally more robust than "Nimbus".
wenzelm@61529
   368
wenzelm@62163
   369
* Update to jedit-5.3.0, with improved GUI scaling and support of
wenzelm@62163
   370
high-resolution displays (e.g. 4K).
wenzelm@62163
   371
wenzelm@62034
   372
* The main Isabelle executable is managed as single-instance Desktop
wenzelm@62034
   373
application uniformly on all platforms: Linux, Windows, Mac OS X.

*** Document preparation ***
wenzelm@61405
   377
wenzelm@62017
   378
* Commands 'paragraph' and 'subparagraph' provide additional section
wenzelm@62017
   379
headings. Thus there are 6 levels of standard headings, as in HTML.
wenzelm@62017
   380
wenzelm@62017
   381
* Command 'text_raw' has been clarified: input text is processed as in
wenzelm@62017
   382
'text' (with antiquotations and control symbols). The key difference is
wenzelm@62017
   383
the lack of the surrounding isabelle markup environment in output.
wenzelm@62017
   384
wenzelm@62017
   385
* Text is structured in paragraphs and nested lists, using notation that
wenzelm@62017
   386
is similar to Markdown. The control symbols for list items are as
wenzelm@62017
   387
follows:
wenzelm@62017
   388
wenzelm@62017
   389
  \<^item>  itemize
wenzelm@62017
   390
  \<^enum>  enumerate
wenzelm@62017
   391
  \<^descr>  description
wenzelm@62017
   392
wenzelm@61491
   393
* There is a new short form for antiquotations with a single argument
wenzelm@61491
   394
that is a cartouche: \<^name>\<open>...\<close> is equivalent to @{name \<open>...\<close>} and
wenzelm@61595
   395
\<open>...\<close> without control symbol is equivalent to @{cartouche \<open>...\<close>}.
wenzelm@61595
   396
\<^name> without following cartouche is equivalent to @{name}. The
wenzelm@61501
   397
standard Isabelle fonts provide glyphs to render important control
wenzelm@61501
   398
symbols, e.g. "\<^verbatim>", "\<^emph>", "\<^bold>".
wenzelm@61491
   399
wenzelm@61595
   400
* Antiquotations @{noindent}, @{smallskip}, @{medskip}, @{bigskip} with
wenzelm@61595
   401
corresponding control symbols \<^noindent>, \<^smallskip>, \<^medskip>, \<^bigskip> specify spacing formally, using
wenzelm@61595
   402
standard LaTeX macros of the same names.
wenzelm@61595
   403
wenzelm@61491
   404
* Antiquotation @{cartouche} in Isabelle/Pure is the same as @{text}.
wenzelm@61491
   405
Consequently, \<open>...\<close> without any decoration prints literal quasi-formal
wenzelm@61492
   406
text. Command-line tool "isabelle update_cartouches -t" helps to update
wenzelm@61492
   407
old sources, by approximative patching of the content of string and
wenzelm@61492
   408
cartouche tokens seen in theory sources.
wenzelm@61491
   409
wenzelm@61491
   410
* The @{text} antiquotation now ignores the antiquotation option
wenzelm@61491
   411
"source". The given text content is output unconditionally, without any
wenzelm@61491
   412
surrounding quotes etc. Subtle INCOMPATIBILITY, put quotes into the
wenzelm@61494
   413
argument where they are really intended, e.g. @{text \<open>"foo"\<close>}. Initial
wenzelm@61494
   414
or terminal spaces are ignored.
wenzelm@61491
   415
wenzelm@62017
   416
* Antiquotations @{emph} and @{bold} output LaTeX source recursively,
wenzelm@62017
   417
adding appropriate text style markup. These may be used in the short
wenzelm@62017
   418
form \<^emph>\<open>...\<close> and \<^bold>\<open>...\<close>.
wenzelm@62017
   419
wenzelm@62017
   420
* Document antiquotation @{footnote} outputs LaTeX source recursively,
wenzelm@62017
   421
marked as \footnote{}. This may be used in the short form \<^footnote>\<open>...\<close>.
wenzelm@62017
   422
wenzelm@62017
   423
* Antiquotation @{verbatim [display]} supports option "indent".
wenzelm@62017
   424
wenzelm@62017
   425
* Antiquotation @{theory_text} prints uninterpreted theory source text
wenzelm@62231
   426
(Isar outer syntax with command keywords etc.). This may be used in the
wenzelm@62231
   427
short form \<^theory_text>\<open>...\<close>. @{theory_text [display]} supports option "indent".
wenzelm@62017
   428
wenzelm@62017
   429
* Antiquotation @{doc ENTRY} provides a reference to the given
wenzelm@62017
   430
documentation, with a hyperlink in the Prover IDE.
wenzelm@62017
   431
wenzelm@62017
   432
* Antiquotations @{command}, @{method}, @{attribute} print checked
wenzelm@62017
   433
entities of the Isar language.
wenzelm@62017
   434
wenzelm@61471
   435
* HTML presentation uses the standard IsabelleText font and Unicode
wenzelm@61471
   436
rendering of Isabelle symbols like Isabelle/Scala/jEdit.  The former
wenzelm@61488
   437
print mode "HTML" loses its special meaning.
wenzelm@61471

*** Isar ***
wenzelm@60406
   441
wenzelm@62205
   442
* Local goals ('have', 'show', 'hence', 'thus') allow structured rule
wenzelm@62205
   443
statements like fixes/assumes/shows in theorem specifications, but the
wenzelm@62205
   444
notation is postfix with keywords 'if' (or 'when') and 'for'. For
wenzelm@60555
   445
example:
wenzelm@60414
   446
wenzelm@60414
   447
  have result: "C x y"
wenzelm@60414
   448
    if "A x" and "B y"
wenzelm@60414
   449
    for x :: 'a and y :: 'a
wenzelm@60414
   450
    <proof>
wenzelm@60414
   451
wenzelm@60449
   452
The local assumptions are bound to the name "that". The result is
wenzelm@60449
   453
exported from context of the statement as usual. The above roughly
wenzelm@60414
   454
corresponds to a raw proof block like this:
wenzelm@60414
   455
wenzelm@60414
   456
  {
wenzelm@60414
   457
    fix x :: 'a and y :: 'a
wenzelm@60449
   458
    assume that: "A x" "B y"
wenzelm@60414
   459
    have "C x y" <proof>
wenzelm@60414
   460
  }
wenzelm@60414
   461
  note result = this
wenzelm@60406
   462
wenzelm@60555
   463
The keyword 'when' may be used instead of 'if', to indicate 'presume'
wenzelm@60555
   464
instead of 'assume' above.
wenzelm@60555
   465
wenzelm@61733
   466
* Assumptions ('assume', 'presume') allow structured rule statements
wenzelm@61733
   467
using 'if' and 'for', similar to 'have' etc. above. For example:
wenzelm@61658
   468
wenzelm@61658
   469
  assume result: "C x y"
wenzelm@61658
   470
    if "A x" and "B y"
wenzelm@61658
   471
    for x :: 'a and y :: 'a
wenzelm@61658
   472
wenzelm@61658
   473
This assumes "\<And>x y::'a. A x \<Longrightarrow> B y \<Longrightarrow> C x y" and produces a general
wenzelm@61658
   474
result as usual: "A ?x \<Longrightarrow> B ?y \<Longrightarrow> C ?x ?y".
wenzelm@61658
   475
wenzelm@61658
   476
Vacuous quantification in assumptions is omitted, i.e. a for-context
wenzelm@61658
   477
only effects propositions according to actual use of variables. For
wenzelm@61658
   478
example:
wenzelm@61658
   479
wenzelm@61658
   480
  assume "A x" and "B y" for x and y
wenzelm@61658
   481
wenzelm@61658
   482
is equivalent to:
wenzelm@61658
   483
wenzelm@61658
   484
  assume "\<And>x. A x" and "\<And>y. B y"
wenzelm@61658
   485
wenzelm@60595
   486
* The meaning of 'show' with Pure rule statements has changed: premises
wenzelm@60595
   487
are treated in the sense of 'assume', instead of 'presume'. This means,
wenzelm@62205
   488
a goal like "\<And>x. A x \<Longrightarrow> B x \<Longrightarrow> C x" can be solved completely as
wenzelm@62205
   489
follows:
wenzelm@60595
   490
wenzelm@60595
   491
  show "\<And>x. A x \<Longrightarrow> B x \<Longrightarrow> C x"
wenzelm@60595
   492
wenzelm@60595
   493
or:
wenzelm@60595
   494
wenzelm@60595
   495
  show "C x" if "A x" "B x" for x
wenzelm@60595
   496
wenzelm@60595
   497
Rare INCOMPATIBILITY, the old behaviour may be recovered as follows:
wenzelm@60595
   498
wenzelm@60595
   499
  show "C x" when "A x" "B x" for x
wenzelm@60595
   500
wenzelm@60459
   501
* New command 'consider' states rules for generalized elimination and
wenzelm@60459
   502
case splitting. This is like a toplevel statement "theorem obtains" used
wenzelm@60459
   503
within a proof body; or like a multi-branch 'obtain' without activation
wenzelm@60459
   504
of the local context elements yet.
wenzelm@60459
   505
wenzelm@60455
   506
* Proof method "cases" allows to specify the rule as first entry of
wenzelm@60455
   507
chained facts.  This is particularly useful with 'consider':
wenzelm@60455
   508
wenzelm@60455
   509
  consider (a) A | (b) B | (c) C <proof>
wenzelm@60455
   510
  then have something
wenzelm@60455
   511
  proof cases
wenzelm@60455
   512
    case a
wenzelm@60455
   513
    then show ?thesis <proof>
wenzelm@60455
   514
  next
wenzelm@60455
   515
    case b
wenzelm@60455
   516
    then show ?thesis <proof>
wenzelm@60455
   517
  next
wenzelm@60455
   518
    case c
wenzelm@60455
   519
    then show ?thesis <proof>
wenzelm@60455
   520
  qed
wenzelm@60455
   521
wenzelm@60565
   522
* Command 'case' allows fact name and attribute specification like this:
wenzelm@60565
   523
wenzelm@60565
   524
  case a: (c xs)
wenzelm@60565
   525
  case a [attributes]: (c xs)
wenzelm@60565
   526
wenzelm@60565
   527
Facts that are introduced by invoking the case context are uniformly
wenzelm@60565
   528
qualified by "a"; the same name is used for the cumulative fact. The old
wenzelm@60565
   529
form "case (c xs) [attributes]" is no longer supported. Rare

* The standard proof method of commands 'proof' and '..' is now called
wenzelm@60618
   534
"standard" to make semantically clear what it is; the old name "default"
wenzelm@60618
   535
is still available as legacy for some time. Documentation now explains
wenzelm@60618
   536
'..' more accurately as "by standard" instead of "by rule".

* Nesting of Isar goal structure has been clarified: the context after
wenzelm@62017
   539
the initial backwards refinement is retained for the whole proof, within
wenzelm@62017
   540
all its context sections (as indicated via 'next'). This is e.g.
wenzelm@62017
   541
relevant for 'using', 'including', 'supply':
wenzelm@62017
   542
wenzelm@62017
   543
  have "A \<and> A" if a: A for A
wenzelm@62017

* Command 'obtain' binds term abbreviations (via 'is' patterns) in the
wenzelm@62017
   552
proof body as well, abstracted over relevant parameters.
wenzelm@62017

* Improved type-inference for theorem statement 'obtains': separate

   555
parameter scope for of each clause.
wenzelm@62017
   556
wenzelm@62017
   557
* Term abbreviations via 'is' patterns also work for schematic

   558
statements: result is abstracted over unknowns.
wenzelm@62017
   559
wenzelm@60631
   560
* Command 'subgoal' allows to impose some structure on backward
wenzelm@60631
   561
refinements, to avoid proof scripts degenerating into long of 'apply'
wenzelm@60631
   562
sequences. Further explanations and examples are given in the isar-ref
wenzelm@60631

* Proof method "goal_cases" turns the current subgoals into cases within
wenzelm@61166
   569
the context; the conclusion is bound to variable ?case in each case. For

* The undocumented feature of implicit cases goal1, goal2, goal3, etc.
wenzelm@60617
   593
is marked as legacy, and will be removed eventually. The proof method
wenzelm@60617
   594
"goals" achieves a similar effect within regular Isar; often it can be
wenzelm@60617
   595
done more adequately by other means (e.g. 'consider').
wenzelm@60581
   596
wenzelm@62017
   597
* The vacuous fact "TERM x" may be established "by fact" or as `TERM x`
wenzelm@62017
   598
as well, not just "by this" or "." as before.
wenzelm@60551
   599
wenzelm@60554

* Method "sleep" succeeds after a real-time delay (in seconds). This is
wenzelm@60554
   601
occasionally useful for demonstration and testing purposes.

* Qualifiers in locale expressions default to mandatory ('!') regardless
wenzelm@61606
   607
of the command. Previously, for 'locale' and 'sublocale' the default was
wenzelm@61606
   608
optional ('?'). The old synatx '!' has been discontinued.
wenzelm@61606
   609
INCOMPATIBILITY, remove '!' and add '?' as required.

* Keyword 'rewrites' identifies rewrite morphisms in interpretation
wenzelm@62017

commands. Previously, the keyword was 'where'. INCOMPATIBILITY.
ballarin@61566

ballarin@61701

* More gentle suppression of syntax along locale morphisms while
wenzelm@62017
   615
printing terms. Previously 'abbreviation' and 'notation' declarations
wenzelm@62017
   616
would be suppressed for morphisms except term identity. Now
ballarin@61701
   617
'abbreviation' is also kept for morphims that only change the involved
wenzelm@62017
   618
parameters, and only 'notation' is suppressed. This can be of great help
wenzelm@62017
   619
when working with complex locale hierarchies, because proof states are
wenzelm@62017
   620
displayed much more succinctly. It also means that only notation needs
wenzelm@62017
   621
to be redeclared if desired, as illustrated by this example:
ballarin@61701
   622
ballarin@61701
   623
  locale struct = fixes composition :: "'a => 'a => 'a" (infixl "\<cdot>" 65)

ballarin@61701
   627
ballarin@61701
   628
  locale morphism =
ballarin@61701
   629
    left: struct composition + right: struct composition'
ballarin@61701
   630
    for composition (infix "\<cdot>" 65) and composition' (infix "\<cdot>''" 65)

* Command 'global_interpretation' issues interpretations into global
wenzelm@61895

theories, with optional rewrite definitions following keyword 'defines'.
wenzelm@61895
   637
wenzelm@61895
   638
* Command 'sublocale' accepts optional rewrite definitions after keyword
haftmann@61675
   639

haftmann@61675
   640
wenzelm@61895
   641

'global_interpretation' or 'sublocale' instead. INCOMPATIBILITY.
haftmann@61670

wenzelm@61252

* Command 'print_definitions' prints dependencies of definitional
wenzelm@61252

wenzelm@61252
   646
wenzelm@60331

   661
* The 'typedef' command has been upgraded from a partially checked
wenzelm@62017
   662
"axiomatization", to a full definitional specification that takes the
wenzelm@62017
   663
global collection of overloaded constant / type definitions into
wenzelm@62017
   664
account. Type definitions with open dependencies on overloaded
wenzelm@62017
   665
definitions need to be specified as "typedef (overloaded)". This
wenzelm@62017
   666
provides extra robustness in theory construction. Rare INCOMPATIBILITY.
wenzelm@62017
   667
wenzelm@62017
   668
* Qualification of various formal entities in the libraries is done more
wenzelm@62017
   669
uniformly via "context begin qualified definition ... end" instead of
wenzelm@62017
   670
old-style "hide_const (open) ...". Consequently, both the defined
wenzelm@62017
   671
constant and its defining fact become qualified, e.g. Option.is_none and
wenzelm@62017
   672
Option.is_none_def. Occasional INCOMPATIBILITY in applications.
wenzelm@62017
   673
wenzelm@62017

* Some old and rarely used ASCII replacement syntax has been removed.
wenzelm@62017
   675
INCOMPATIBILITY, standard syntax with symbols should be used instead.

* The alternative notation "\<Colon>" for type and sort constraints has been
wenzelm@62017
   705
removed: in LaTeX document output it looks the same as "::".
wenzelm@62017

   707
wenzelm@62017
   708
* Commands 'inductive' and 'inductive_set' work better when names for
wenzelm@62017
   709
intro rules are omitted: the "cases" and "induct" rules no longer
wenzelm@62017
   710
declare empty case_names, but no case_names at all. This allows to use
wenzelm@62017
   711
numbered cases in proofs, without requiring method "goal_cases".
wenzelm@62017
   712
wenzelm@62017
   713
* Inductive definitions ('inductive', 'coinductive', etc.) expose
wenzelm@62017
   714
low-level facts of the internal construction only if the option
wenzelm@62093
   715
"inductive_internals" is enabled. This refers to the internal predicate

wenzelm@60138
   815
blanchet@60306
   816
* Sledgehammer:
blanchet@61318
   817
  - The MaSh relevance filter has been sped up.
blanchet@60306
   818
  - Proof reconstruction has been improved, to minimize the incidence of
blanchet@60306
   819
    cases where Sledgehammer gives a proof that does not work.
blanchet@60306
   820
  - Auto Sledgehammer now minimizes and preplays the results.
blanchet@61030
   821
  - Handle Vampire 4.0 proof output without raising exception.
blanchet@61043
   822
  - Eliminated "MASH" environment variable. Use the "MaSh" option in
blanchet@61043
   823
    Isabelle/jEdit instead. INCOMPATIBILITY.
blanchet@61317
   824
  - Eliminated obsolete "blocking" option and related subcommands.
blanchet@60306
   825
blanchet@60310

* Nitpick:
blanchet@61325
   827
  - Fixed soundness bug in translation of "finite" predicate.
blanchet@61324
   828
  - Fixed soundness bug in "destroy_constrs" optimization.
blanchet@62080
   829

   831
  - Eliminated obsolete "blocking" option.

   832
wenzelm@62027

* (Co)datatype package:
blanchet@61345
   834
  - New commands "lift_bnf" and "copy_bnf" for lifting (copying) a BNF
blanchet@61345
   835
    structure on the raw type to an abstract type defined using typedef.
blanchet@61345
   836
  - Always generate "case_transfer" theorem.
wenzelm@62235
   837
  - For mutual types, generate slightly stronger "rel_induct",
wenzelm@62235
   838
    "rel_coinduct", and "coinduct" theorems. INCOMPATIBLITY.
blanchet@61551
   839
  - Allow discriminators and selectors with the same name as the type
blanchet@61551

blanchet@61551
   841
  - Avoid various internal name clashes (e.g., 'datatype f = f').

* Division on integers is bootstrapped directly from division on
wenzelm@62017
   850
naturals and uses generic numeral algorithm for computations. Slight
wenzelm@62017

   853
wenzelm@62017

haftmann@60516
   855
INCOMPATIBILITY.
haftmann@60516
   856
haftmann@60688
   857
* Class algebraic_semidom introduces common algebraic notions of
wenzelm@62017
   858
integral (semi)domains, particularly units. Although logically subsumed
wenzelm@62017
   859
by fields, is is not a super class of these in order not to burden
wenzelm@62017
   860
fields with notions that are trivial there.
wenzelm@62017
   861
wenzelm@62017
   862
* Class normalization_semidom specifies canonical representants for
wenzelm@62017
   863
equivalence classes of associated elements in an integral (semi)domain.
wenzelm@62017
   864
This formalizes associated elements as well.
haftmann@60688

haftmann@60688
   866
* Abstract specification of gcd/lcm operations in classes semiring_gcd,
wenzelm@62017
   867
semiring_Gcd, semiring_Lcd. Minor INCOMPATIBILITY: facts gcd_nat.commute
wenzelm@62017
   868
and gcd_int.commute are subsumed by gcd.commute, as well as
wenzelm@62017

gcd_nat.assoc and gcd_int.assoc by gcd.assoc.
wenzelm@62017
   870
wenzelm@62017
   871
* Former constants Fields.divide (_ / _) and Divides.div (_ div _) are
wenzelm@62017
   872
logically unified to Rings.divide in syntactic type class Rings.divide,
wenzelm@62017
   873
with infix syntax (_ div _). Infix syntax (_ / _) for field division is
wenzelm@62017
   874
added later as abbreviation in class Fields.inverse. INCOMPATIBILITY,
wenzelm@62017
   875
instantiations must refer to Rings.divide rather than the former
wenzelm@62017
   876
separate constants, hence infix syntax (_ / _) is usually not available
wenzelm@62017
   877
during instantiation.
wenzelm@62017
   878
wenzelm@62017
   879
* New cancellation simprocs for boolean algebras to cancel complementary
wenzelm@62017
   880
terms for sup and inf. For example, "sup x (sup y (- x))" simplifies to
wenzelm@62017
   881
"top". INCOMPATIBILITY.

and metric spaces. Minor INCOMPATIBILITY: open_<type>_def needs to be
wenzelm@62205
   885
introduced in the form of an uniformity. Some constants are more general
wenzelm@62205
   886
now, it may be necessary to add type class constraints.

      \<supset>#
blanchet@62209
   906
      \<supseteq>#
Mathias@60397
   907
  - "'a multiset" is no longer an instance of the "order",
Mathias@60397
   908
    "ordered_ab_semigroup_add_imp_le", "ordered_cancel_comm_monoid_diff",
Mathias@60397
   909
    "semilattice_inf", and "semilattice_sup" type classes. The theorems
Mathias@60397
   910
    previously provided by these type classes (directly or indirectly)
Mathias@60397
   911
    are now available through the "subset_mset" interpretation

Mathias@60397
   913
    INCOMPATIBILITY.
nipkow@60497

    INCOMPATIBILITY
Mathias@60398

wenzelm@62084
   949
remove '!' and add '?' as required.

improved: proper treatment of break offsets and blocks with consistent
wenzelm@61922
   991
breaks.
wenzelm@61922
   992
wenzelm@61268
   993
* The auxiliary module Pure/display.ML has been eliminated. Its
wenzelm@61268
   994
elementary thm print operations are now in Pure/more_thm.ML and thus
wenzelm@61268
   995

wenzelm@61268

* Simproc programming interfaces have been simplified:
wenzelm@61144

Simplifier.make_simproc and Simplifier.define_simproc supersede various
wenzelm@61144
   999
forms of Simplifier.mk_simproc, Simplifier.simproc_global etc. Note that
wenzelm@61144
  1000

  1001
fixed variables, like top-level theorem statements. INCOMPATIBILITY.
wenzelm@61144

  Thm.instantiate  (*low-level instantiation with named arguments*)
wenzelm@60802

  Drule.infer_instantiate'  (*version with positional arguments*)
wenzelm@60802
  1010
wenzelm@60802
  1011
The LHS only requires variable specifications, instead of full terms.
wenzelm@60802
  1012
Old cterm_instantiate is superseded by infer_instantiate.
wenzelm@60802
  1013
INCOMPATIBILITY, need to re-adjust some ML names and types accordingly.
wenzelm@60802

* Old tactic shorthands atac, rtac, etac, dtac, ftac have been
wenzelm@60793
  1016
discontinued. INCOMPATIBILITY, use regular assume_tac, resolve_tac etc.
wenzelm@60793
  1017
instead (with proper context).
wenzelm@60642
  1018
wenzelm@60642
  1019
* Thm.instantiate (and derivatives) no longer require the LHS of the
wenzelm@60642

instantiation to be certified: plain variables are given directly.
wenzelm@60642
  1021
wenzelm@60707
  1022
* Subgoal.SUBPROOF and Subgoal.FOCUS combinators use anonymous
wenzelm@60707
  1023
quasi-bound variables (like the Simplifier), instead of accidentally
wenzelm@60707
  1024
named local fixes. This has the potential to improve stability of proof
wenzelm@60707
  1025
tools, but can also cause INCOMPATIBILITY for tools that don't observe
wenzelm@60707
  1026
the proof context discipline.
wenzelm@60707

wenzelm@62017

wenzelm@62017
  1029
context_tactic, which allows to change the proof context dynamically
wenzelm@62017
  1030
(e.g. to update cases) and indicate explicit Seq.Error results. Former

* Bash shell function "jvmpath" has been renamed to "platform_path": it
wenzelm@61294
  1074
is relevant both for Poly/ML and JVM processes.
wenzelm@61294
  1075
wenzelm@62017
  1076
* Poly/ML default platform architecture may be changed from 32bit to
wenzelm@62205
  1077
64bit via system option ML_system_64. A system restart (and rebuild) is
wenzelm@62205
  1078
required after change.

* Poly/ML 5.6 runs natively on x86-windows and x86_64-windows, which
wenzelm@62017
  1081
both allow larger heap space than former x86-cygwin.
wenzelm@62017
  1082
wenzelm@62157
  1083
* Heap images are 10-15% smaller due to less wasteful persistent theory

*** General ***
wenzelm@57941
  1092
wenzelm@59939
  1093
* Local theory specification commands may have a 'private' or
wenzelm@59990
  1094
'qualified' modifier to restrict name space accesses to the local scope,
wenzelm@59939
  1095
as provided by some "context begin ... end" block. For example:
wenzelm@59926
  1096
wenzelm@59926
  1097
  context
wenzelm@59926
  1098
  begin
wenzelm@59926
  1099
wenzelm@59926
  1100

wenzelm@59926
  1110
wenzelm@59901
  1111
* Command 'experiment' opens an anonymous locale context with private
wenzelm@59901
  1112
naming policy.
wenzelm@59901
  1113
wenzelm@59951
  1114
* Command 'notepad' requires proper nesting of begin/end and its proof
wenzelm@59951
  1115
structure in the body: 'oops' is no longer supported here. Minor
wenzelm@59951
  1116
INCOMPATIBILITY, use 'sorry' instead.
wenzelm@59951
  1117
wenzelm@59951
  1118
* Command 'named_theorems' declares a dynamic fact within the context,
wenzelm@59951
  1119
together with an attribute to maintain the content incrementally. This
wenzelm@59951
  1120
supersedes functor Named_Thms in Isabelle/ML, but with a subtle change
wenzelm@59951
  1121
of semantics due to external visual order vs. internal reverse order.
wenzelm@59951
  1122
wenzelm@59951
  1123
* 'find_theorems': search patterns which are abstractions are
wenzelm@59951
  1124
schematically expanded before search. Search results match the naive
wenzelm@59951
  1125
expectation more closely, particularly wrt. abbreviations.
wenzelm@59951
  1126
INCOMPATIBILITY.
wenzelm@59648
  1127
wenzelm@59569
  1128
* Commands 'method_setup' and 'attribute_setup' now work within a local
wenzelm@59569
  1129
theory context.
wenzelm@57941
  1130
wenzelm@58928
  1131
* Outer syntax commands are managed authentically within the theory
wenzelm@59569
  1132
context, without implicit global state. Potential for accidental
wenzelm@58928
  1133
INCOMPATIBILITY, make sure that required theories are really imported.
wenzelm@58928
  1134
wenzelm@60115
  1135
* Historical command-line terminator ";" is no longer accepted (and
wenzelm@60115
  1136
already used differently in Isar). Minor INCOMPATIBILITY, use "isabelle
wenzelm@60115
  1137
update_semicolons" to remove obsolete semicolons from old theory
wenzelm@60115
  1138
sources.
wenzelm@60115
  1139
wenzelm@59951
  1140
* Structural composition of proof methods (meth1; meth2) in Isar
wenzelm@59951
  1141
corresponds to (tac1 THEN_ALL_NEW tac2) in ML.
haftmann@59105
  1142
wenzelm@60119
  1143
* The Eisbach proof method language allows to define new proof methods
wenzelm@60119
  1144
by combining existing ones with their usual syntax. The "match" proof
wenzelm@60119
  1145
method provides basic fact/term matching in addition to
wenzelm@60119
  1146
premise/conclusion matching through Subgoal.focus, and binds fact names
wenzelm@60288
  1147
from matches as well as term patterns within matches. The Isabelle
wenzelm@60288
  1148
documentation provides an entry "eisbach" for the Eisbach User Manual.
wenzelm@60288
  1149
Sources and various examples are in ~~/src/HOL/Eisbach/.

*** Prover IDE -- Isabelle/Scala/jEdit ***
wenzelm@58524
  1153
wenzelm@59569
  1154
* Improved folding mode "isabelle" based on Isar syntax. Alternatively,
wenzelm@59569
  1155
the "sidekick" mode may be used for document structure.
wenzelm@59569
  1156
wenzelm@59569
  1157
* Extended bracket matching based on Isar language structure. System
wenzelm@59569
  1158
option jedit_structure_limit determines maximum number of lines to scan
wenzelm@59569
  1159
in the buffer.
wenzelm@58758
  1160
wenzelm@58540
  1161
* Support for BibTeX files: context menu, context-sensitive token
wenzelm@58540
  1162
marker, SideKick parser.
wenzelm@58524
  1163
wenzelm@58551
  1164
* Document antiquotation @{cite} provides formal markup, which is
wenzelm@60265
  1165
interpreted semi-formally based on .bib files that happen to be open in
wenzelm@60265
  1166
the editor (hyperlinks, completion etc.).
wenzelm@58551
  1167
wenzelm@58785
  1168
* Less waste of vertical space via negative line spacing (see Global
wenzelm@58785
  1169
Options / Text Area).
wenzelm@58785
  1170
wenzelm@60089
  1171
* Improved graphview panel with optional output of PNG or PDF, for
wenzelm@60273
  1172
display of 'thy_deps', 'class_deps' etc.
wenzelm@60009
  1173
wenzelm@60115
  1174
* The commands 'thy_deps' and 'class_deps' allow optional bounds to
wenzelm@60115
  1175
restrict the visualized hierarchy.
wenzelm@60093
  1176
wenzelm@60072
  1177
* Improved scheduling for asynchronous print commands (e.g. provers
wenzelm@60072
  1178
managed by the Sledgehammer panel) wrt. ongoing document processing.
wenzelm@60072
  1179
wenzelm@58524
  1180
wenzelm@59951
  1181
*** Document preparation ***
wenzelm@59951
  1182
wenzelm@59951
  1183
* Document markup commands 'chapter', 'section', 'subsection',
wenzelm@59951
  1184
'subsubsection', 'text', 'txt', 'text_raw' work uniformly in any
wenzelm@59951
  1185
context, even before the initial 'theory' command. Obsolete proof
wenzelm@59951
  1186
commands 'sect', 'subsect', 'subsubsect', 'txt_raw' have been
wenzelm@59951
  1187
discontinued, use 'section', 'subsection', 'subsubsection', 'text_raw'
wenzelm@59951
  1188
instead. The old 'header' command is still retained for some time, but
wenzelm@59951
  1189
should be replaced by 'chapter', 'section' etc. (using "isabelle
wenzelm@59951
  1190
update_header"). Minor INCOMPATIBILITY.
wenzelm@59951
  1191
wenzelm@60009
  1192
* Official support for "tt" style variants, via \isatt{...} or
wenzelm@60009
  1193
\begin{isabellett}...\end{isabellett}. The somewhat fragile \verb or
wenzelm@60009
  1194
verbatim environment of LaTeX is no longer used. This allows @{ML} etc.
wenzelm@60009
  1195
as argument to other macros (such as footnotes).
wenzelm@60009
  1196
wenzelm@60009
  1197
* Document antiquotation @{verbatim} prints ASCII text literally in "tt"
wenzelm@60009
  1198
style.
wenzelm@60009
  1199
wenzelm@60009
  1200
* Discontinued obsolete option "document_graph": session_graph.pdf is
wenzelm@60009
  1201
produced unconditionally for HTML browser_info and PDF-LaTeX document.
wenzelm@60009
  1202
wenzelm@59951
  1203
* Diagnostic commands and document markup commands within a proof do not
wenzelm@59951
  1204
affect the command tag for output. Thus commands like 'thm' are subject
wenzelm@59951
  1205
to proof document structure, and no longer "stick out" accidentally.
wenzelm@59951
  1206
Commands 'text' and 'txt' merely differ in the LaTeX style, not their
wenzelm@59951
  1207
tags. Potential INCOMPATIBILITY in exotic situations.
wenzelm@59951
  1208
wenzelm@59951
  1209
* System option "pretty_margin" is superseded by "thy_output_margin",
wenzelm@59951
  1210
which is also accessible via document antiquotation option "margin".
wenzelm@59951
  1211
Only the margin for document output may be changed, but not the global
wenzelm@59951
  1212
pretty printing: that is 76 for plain console output, and adapted
wenzelm@59951
  1213
dynamically in GUI front-ends. Implementations of document
wenzelm@59951
  1214
antiquotations need to observe the margin explicitly according to
wenzelm@59951
  1215
Thy_Output.string_of_margin. Minor INCOMPATIBILITY.
wenzelm@59951
  1216
wenzelm@60299
  1217
* Specification of 'document_files' in the session ROOT file is
wenzelm@60299
  1218
mandatory for document preparation. The legacy mode with implicit
wenzelm@60299
  1219
copying of the document/ directory is no longer supported. Minor
wenzelm@60299
  1220
INCOMPATIBILITY.

*** Pure ***
haftmann@58202
  1224
wenzelm@59835
  1225
* Proof methods with explicit instantiation ("rule_tac", "subgoal_tac"
wenzelm@59835
  1226
etc.) allow an optional context of local variables ('for' declaration):
wenzelm@59835
  1227
these variables become schematic in the instantiated theorem; this
wenzelm@59835
  1228
behaviour is analogous to 'for' in attributes "where" and "of".
wenzelm@59835
  1229
Configuration option rule_insts_schematic (default false) controls use
wenzelm@59835
  1230
of schematic variables outside the context. Minor INCOMPATIBILITY,
wenzelm@59835
  1231
declare rule_insts_schematic = true temporarily and update to use local
wenzelm@59835
  1232
variable declarations or dummy patterns instead.
wenzelm@59835
  1233
wenzelm@60009
  1234
* Explicit instantiation via attributes "where", "of", and proof methods
wenzelm@60009
  1235
"rule_tac" with derivatives like "subgoal_tac" etc. admit dummy patterns
wenzelm@60009
  1236
("_") that stand for anonymous local variables.
wenzelm@60009
  1237
wenzelm@59951
  1238
* Generated schematic variables in standard format of exported facts are
wenzelm@59951
  1239
incremented to avoid material in the proof context. Rare
wenzelm@59951
  1240
INCOMPATIBILITY, explicit instantiation sometimes needs to refer to
wenzelm@59951
  1241
different index.
wenzelm@59951
  1242
wenzelm@60010
  1243
* Lexical separation of signed and unsigned numerals: categories "num"
wenzelm@60010
  1244
and "float" are unsigned. INCOMPATIBILITY: subtle change in precedence
wenzelm@60010
  1245
of numeral signs, particularly in expressions involving infix syntax
wenzelm@60010
  1246
like "(- 1) ^ n".
haftmann@58410
  1247
wenzelm@58421
  1248
* Old inner token category "xnum" has been discontinued.  Potential
wenzelm@58421
  1249
INCOMPATIBILITY for exotic syntax: may use mixfix grammar with "num"
wenzelm@58421
  1250
token category instead.

* Old and new SMT modules:
blanchet@58067
  1341
  - The old 'smt' method has been renamed 'old_smt' and moved to
wenzelm@59569

    'src/HOL/Library/Old_SMT.thy'. It is provided for compatibility,
wenzelm@59569
  1343
    until applications have been ported to use the new 'smt' method. For
wenzelm@59569
  1344
    the method to work, an older version of Z3 (e.g. Z3 3.2 or 4.0) must
wenzelm@59569

* Lifting: command 'lift_definition' allows to execute lifted constants
wenzelm@60261
  1356
that have as a return type a datatype containing a subtype. This
wenzelm@60261
  1357
overcomes long-time limitations in the area of code generation and
wenzelm@60261
  1358
lifting, and avoids tedious workarounds.

* Command and antiquotation "value" provide different evaluation slots
wenzelm@60009
  1361
(again), where the previous strategy (NBE after ML) serves as default.
wenzelm@60009
  1362
Minor INCOMPATIBILITY.

wenzelm@60009
  1365
wenzelm@60009
  1366
* field_simps: Use NO_MATCH-simproc for distribution rules, to avoid
wenzelm@60009
  1367
non-termination in case of distributing a division. With this change
wenzelm@60009
  1368
field_simps is in some cases slightly less powerful, if it fails try to
wenzelm@60009
  1369
add algebra_simps, or use divide_simps. Minor INCOMPATIBILITY.

wenzelm@60009
  1379
field_inverse_zero and linordered_field_inverse_zero. INCOMPATIBILITY.

wenzelm@60009
  1389
"{real_normed_algebra_1,banach}" type, so in particular on "real" and
wenzelm@60009
  1390
"complex" uniformly. Minor INCOMPATIBILITY: type constraints may be

wenzelm@60009
  1392
wenzelm@60009
  1393
* New library of properties of the complex transcendental functions sin,

cos, tan, exp, Ln, Arctan, Arcsin, Arccos. Ported from HOL Light.
wenzelm@60009

wenzelm@60009
  1396
* The factorial function, "fact", now has type "nat => 'a" (of a sort
wenzelm@60009
  1397
that admits numeric types including nat, int, real and complex.
wenzelm@60009
  1398
INCOMPATIBILITY: an expression such as "fact 3 = 6" may require a type
wenzelm@60009
  1399
constraint, and the combination "real (fact k)" is likely to be
wenzelm@60009
  1400
unsatisfactory. If a type conversion is still necessary, then use
wenzelm@60009
  1401
"of_nat (fact k)" or "real_of_nat (fact k)".
wenzelm@60009
  1402
wenzelm@60009
  1403
* Removed functions "natfloor" and "natceiling", use "nat o floor" and
wenzelm@60009
  1404
"nat o ceiling" instead. A few of the lemmas have been retained and
wenzelm@60009
  1405
adapted: in their names "natfloor"/"natceiling" has been replaced by
wenzelm@60009
  1406
"nat_floor"/"nat_ceiling".
wenzelm@60009
  1407
wenzelm@60009
  1408
* Qualified some duplicated fact names required for boostrapping the

double_add_less_zero_iff_single_add_less_zero (simp by default anyway).
wenzelm@60009

  1451
wenzelm@60009
  1452
* Library/Multiset:
blanchet@59813
  1453
  - Introduced "replicate_mset" operation.
blanchet@59813
  1454
  - Introduced alternative characterizations of the multiset ordering in
blanchet@59813
  1455
    "Library/Multiset_Order".
blanchet@59958
  1456
  - Renamed multiset ordering:

blanchet@59986
  1465
    INCOMPATIBILITY.
blanchet@59813

wenzelm@60009
  1484
use local CSDP executable, which is much faster than the NEOS server.
wenzelm@60009
  1485
The "sos_cert" functionality is invoked as "sos" with additional

wenzelm@60009
  1488
* HOL-Decision_Procs: New counterexample generator quickcheck
wenzelm@60009
  1489
[approximation] for inequalities of transcendental functions. Uses
wenzelm@60009
  1490
hardware floating point arithmetic to randomly discover potential

wenzelm@60010
  1496
  - applies destructor rules repeatedly
hoelzl@59354
  1497
  - removed application splitting (replaced by destructor rule)
wenzelm@59569

*** ML ***
blanchet@58066
  1506
wenzelm@60009
  1507
* Subtle change of name space policy: undeclared entries are now
wenzelm@60009
  1508
considered inaccessible, instead of accessible via the fully-qualified
wenzelm@60009
  1509
internal name. This mainly affects Name_Space.intern (and derivatives),
wenzelm@60009
  1510
which may produce an unexpected Long_Name.hidden prefix. Note that
wenzelm@60010
  1511
contemporary applications use the strict Name_Space.check (and
wenzelm@60009
  1512
derivatives) instead, which is not affected by the change. Potential
wenzelm@60009
  1513
INCOMPATIBILITY in rare applications of Name_Space.intern.
wenzelm@59951
  1514
wenzelm@60094
  1515
* Subtle change of error semantics of Toplevel.proof_of: regular user

  1516
ERROR instead of internal Toplevel.UNDEF.
wenzelm@60094
  1517
wenzelm@59951
  1518
* Basic combinators map, fold, fold_map, split_list, apply are available
wenzelm@59951
  1519
as parameterized antiquotations, e.g. @{map 4} for lists of quadruples.
wenzelm@59951
  1520
wenzelm@59951

wenzelm@59951
  1522
INCOMPATIBILITY.
wenzelm@59951
  1523
wenzelm@59951
  1524
* Former combinators NAMED_CRITICAL and CRITICAL for central critical
wenzelm@59951
  1525

wenzelm@59951
  1526
Multithreading.synchronized and its high-level derivative
wenzelm@59951
  1527
Synchronized.var (which is usually sufficient in applications). Subtle
wenzelm@59951
  1528
INCOMPATIBILITY: synchronized access needs to be atomic and cannot be
wenzelm@59951
  1529
nested.
wenzelm@59951
  1530
wenzelm@60009
  1531
* Synchronized.value (ML) is actually synchronized (as in Scala): subtle
wenzelm@60009
  1532
change of semantics with minimal potential for INCOMPATIBILITY.
wenzelm@59899
  1533
wenzelm@59621
  1534
* The main operations to certify logical entities are Thm.ctyp_of and
wenzelm@59621
  1535
Thm.cterm_of with a local context; old-style global theory variants are
wenzelm@59621

available as Thm.global_ctyp_of and Thm.global_cterm_of.
wenzelm@59621
  1537
INCOMPATIBILITY.
wenzelm@59621

blanchet@58066
  1548
PARALLEL_GOALS.
blanchet@58066
  1549
wenzelm@59564
  1550
* Goal.prove_multi is superseded by the fully general Goal.prove_common,
wenzelm@59564
  1551
which also allows to specify a fork priority.
wenzelm@59564
  1552
wenzelm@59936
  1553
* Antiquotation @{command_spec "COMMAND"} is superseded by
wenzelm@59936

* Standard tactics and proof methods such as "clarsimp", "auto" and
wenzelm@57504
  1601
"safe" now preserve equality hypotheses "x = expr" where x is a free
wenzelm@57504
  1602
variable.  Locale assumptions and chained facts containing "x"
wenzelm@57504
  1603
continue to be useful.  The new method "hypsubst_thin" and the
wenzelm@57504
  1604
configuration option "hypsubst_thin" (within the attribute name space)
wenzelm@57504
  1605
restore the previous behavior.  INCOMPATIBILITY, especially where
wenzelm@57504
  1606
induction is done after these methods or when the names of free and
wenzelm@57504
  1607
bound variables clash.  As first approximation, old proofs may be
wenzelm@57504
  1608
repaired by "using [[hypsubst_thin = true]]" in the critical spot.
wenzelm@57504
  1609
wenzelm@56232
  1610
* More static checking of proof methods, which allows the system to
wenzelm@56232
  1611
form a closure over the concrete syntax.  Method arguments should be
wenzelm@56232
  1612
processed in the original proof context as far as possible, before
wenzelm@56232
  1613
operating on the goal state.  In any case, the standard discipline for
wenzelm@56232
  1614
subgoal-addressing needs to be observed: no subgoals or a subgoal
wenzelm@56232
  1615
number that is out of range produces an empty result sequence, not an
wenzelm@56232
  1616
exception.  Potential INCOMPATIBILITY for non-conformant tactical
wenzelm@56232
  1617
proof tools.
wenzelm@56232
  1618
wenzelm@57452
  1619
* Lexical syntax (inner and outer) supports text cartouches with
wenzelm@57452
  1620
arbitrary nesting, and without escapes of quotes etc.  The Prover IDE
wenzelm@57452
  1621
supports input via ` (backquote).
wenzelm@57452
  1622
wenzelm@57452
  1623
* The outer syntax categories "text" (for formal comments and document
wenzelm@57452
  1624
markup commands) and "altstring" (for literal fact references) allow
wenzelm@57452
  1625
cartouches as well, in addition to the traditional mix of quotations.
wenzelm@57452
  1626
wenzelm@57452
  1627
* Syntax of document antiquotation @{rail} now uses \<newline> instead
wenzelm@57452
  1628
of "\\", to avoid the optical illusion of escaped backslash within
wenzelm@57491
  1629
string token.  General renovation of its syntax using text cartouches.
wenzelm@57452
  1630
Minor INCOMPATIBILITY.
wenzelm@57452
  1631
wenzelm@57452
  1632
* Discontinued legacy_isub_isup, which was a temporary workaround for
wenzelm@57452
  1633
Isabelle/ML in Isabelle2013-1.  The prover process no longer accepts
wenzelm@57452
  1634
old identifier syntax with \<^isub> or \<^isup>.  Potential
wenzelm@57452
  1635
INCOMPATIBILITY.
wenzelm@57452
  1636
wenzelm@57452
  1637
* Document antiquotation @{url} produces markup for the given URL,
wenzelm@57452
  1638
which results in an active hyperlink within the text.
wenzelm@57452
  1639
wenzelm@57452
  1640
* Document antiquotation @{file_unchecked} is like @{file}, but does
wenzelm@57452
  1641
not check existence within the file-system.
wenzelm@57452
  1642
wenzelm@57452
  1643
* Updated and extended manuals: codegen, datatypes, implementation,
wenzelm@57452
  1644
isar-ref, jedit, system.

*** Prover IDE -- Isabelle/Scala/jEdit ***
wenzelm@54533
  1648
wenzelm@57650
  1649
* Improved Document panel: simplified interaction where every single
wenzelm@57452
  1650
mouse click (re)opens document via desktop environment or as jEdit
wenzelm@57452
  1651
buffer.
wenzelm@57452
  1652
wenzelm@57452
  1653
* Support for Navigator plugin (with toolbar buttons), with connection
wenzelm@57452
  1654
to PIDE hyperlinks.
wenzelm@57452
  1655
wenzelm@57452
  1656
* Auxiliary files ('ML_file' etc.) are managed by the Prover IDE.
wenzelm@57452
  1657
Open text buffers take precedence over copies within the file-system.
wenzelm@57452
  1658
wenzelm@57452
  1659
* Improved support for Isabelle/ML, with jEdit mode "isabelle-ml" for
wenzelm@57452
  1660
auxiliary ML files.
wenzelm@57423
  1661
wenzelm@57423
  1662
* Improved syntactic and semantic completion mechanism, with simple
wenzelm@57423
  1663
templates, completion language context, name-space completion,
wenzelm@57423
  1664
file-name completion, spell-checker completion.
wenzelm@57423
  1665
wenzelm@57423
  1666
* Refined GUI popup for completion: more robust key/mouse event
wenzelm@57423
  1667
handling and propagation to enclosing text area -- avoid loosing
wenzelm@57423
  1668
keystrokes with slow / remote graphics displays.
wenzelm@57423
  1669
wenzelm@57833
  1670
* Completion popup supports both ENTER and TAB (default) to select an
wenzelm@57833
  1671
item, depending on Isabelle options.
wenzelm@57833
  1672
wenzelm@57423
  1673
* Refined insertion of completion items wrt. jEdit text: multiple
wenzelm@57423
  1674
selections, rectangular selections, rectangular selection as "tall
wenzelm@57423
  1675
caret".
wenzelm@56342
  1676
wenzelm@56580
  1677
* Integrated spell-checker for document text, comments etc. with
wenzelm@57423
  1678
completion popup and context-menu.
wenzelm@56554
  1679
wenzelm@56879
  1680
* More general "Query" panel supersedes "Find" panel, with GUI access
wenzelm@56879
  1681
to commands 'find_theorems' and 'find_consts', as well as print
wenzelm@56879
  1682
operations for the context.  Minor incompatibility in keyboard
wenzelm@56879
  1683
shortcuts etc.: replace action isabelle-find by isabelle-query.
wenzelm@56761
  1684
wenzelm@56901
  1685
* Search field for all output panels ("Output", "Query", "Info" etc.)
wenzelm@56901
  1686
to highlight text via regular expression.
wenzelm@56901
  1687
wenzelm@54881
  1688
* Option "jedit_print_mode" (see also "Plugin Options / Isabelle /
wenzelm@54881
  1689
General") allows to specify additional print modes for the prover
wenzelm@54881
  1690
process, without requiring old-fashioned command-line invocation of
wenzelm@54881
  1691
"isabelle jedit -m MODE".
wenzelm@54881
  1692
wenzelm@56505
  1693
* More support for remote files (e.g. http) using standard Java
wenzelm@56505
  1694
networking operations instead of jEdit virtual file-systems.
wenzelm@56505
  1695
wenzelm@57822
  1696
* Empty editors buffers that are no longer required (e.g.\ via theory
wenzelm@57822
  1697
imports) are automatically removed from the document model.
wenzelm@57822
  1698
wenzelm@57869
  1699
* Improved monitor panel.
wenzelm@57869
  1700
wenzelm@56838
  1701
* Improved Console/Scala plugin: more uniform scala.Console output,
wenzelm@56838
  1702
more robust treatment of threads and interrupts.
wenzelm@56838
  1703
wenzelm@56939
  1704
* Improved management of dockable windows: clarified keyboard focus
wenzelm@56939
  1705
and window placement wrt. main editor view; optional menu item to
wenzelm@56939
  1706
"Detach" a copy where this makes sense.
wenzelm@56939
  1707
wenzelm@57452
  1708
* New Simplifier Trace panel provides an interactive view of the
wenzelm@57591
  1709
simplification process, enabled by the "simp_trace_new" attribute
wenzelm@57452
  1710
within the context.

*** Pure ***
wenzelm@55001
  1714
wenzelm@57504
  1715
* Low-level type-class commands 'classes', 'classrel', 'arities' have
wenzelm@57504
  1716
been discontinued to avoid the danger of non-trivial axiomatization
wenzelm@57504
  1717
that is not immediately visible.  INCOMPATIBILITY, use regular
wenzelm@57504
  1718
'instance' command with proof.  The required OFCLASS(...) theorem
wenzelm@57504
  1719
might be postulated via 'axiomatization' beforehand, or the proof
wenzelm@57504
  1720
finished trivially if the underlying class definition is made vacuous
wenzelm@57504
  1721
(without any assumptions).  See also Isabelle/ML operations
wenzelm@57504
  1722
Axclass.class_axiomatization, Axclass.classrel_axiomatization,
wenzelm@57504
  1723
Axclass.arity_axiomatization.
wenzelm@57504
  1724
wenzelm@56245
  1725
* Basic constants of Pure use more conventional names and are always
wenzelm@56245
  1726
qualified.  Rare INCOMPATIBILITY, but with potentially serious
wenzelm@56245
  1727
consequences, notably for tools in Isabelle/ML.  The following
wenzelm@56245
  1728
renaming needs to be applied:
wenzelm@56245
  1729
wenzelm@56245
  1730
  ==             ~>  Pure.eq
wenzelm@56245
  1731
  ==>            ~>  Pure.imp
wenzelm@56245
  1732
  all            ~>  Pure.all
wenzelm@56245
  1733
  TYPE           ~>  Pure.type
wenzelm@56245
  1734
  dummy_pattern  ~>  Pure.dummy_pattern
wenzelm@56245
  1735
wenzelm@56245
  1736
Systematic porting works by using the following theory setup on a
wenzelm@56245
  1737
*previous* Isabelle version to introduce the new name accesses for the
wenzelm@56245
  1738
old constants:
wenzelm@56245
  1739
wenzelm@56245
  1740
setup {*
wenzelm@56245
  1741
  fn thy => thy
wenzelm@56245
  1742
    |> Sign.root_path
wenzelm@56245
  1743
    |> Sign.const_alias (Binding.qualify true "Pure" @{binding eq}) "=="
wenzelm@56245
  1744
    |> Sign.const_alias (Binding.qualify true "Pure" @{binding imp}) "==>"
wenzelm@56245
  1745
    |> Sign.const_alias (Binding.qualify true "Pure" @{binding all}) "all"
wenzelm@56245
  1746
    |> Sign.restore_naming thy
wenzelm@56245
  1747
*}
wenzelm@56245
  1748
wenzelm@56245
  1749
Thus ML antiquotations like @{const_name Pure.eq} may be used already.
wenzelm@56245
  1750
Later the application is moved to the current Isabelle version, and
wenzelm@56245
  1751
the auxiliary aliases are deleted.
wenzelm@56245
  1752
wenzelm@55143
  1753
* Attributes "where" and "of" allow an optional context of local
wenzelm@55143
  1754
variables ('for' declaration): these variables become schematic in the
wenzelm@55143
  1755
instantiated theorem.
wenzelm@55143
  1756
wenzelm@55152
  1757
* Obsolete attribute "standard" has been discontinued (legacy since
wenzelm@55152
  1758
Isabelle2012).  Potential INCOMPATIBILITY, use explicit 'for' context
wenzelm@55152
  1759
where instantiations with schematic variables are intended (for
wenzelm@55152
  1760
declaration commands like 'lemmas' or attributes like "of").  The
wenzelm@55152
  1761
following temporary definition may help to port old applications:
wenzelm@55152
  1762
wenzelm@55152
  1763
  attribute_setup standard =
wenzelm@55152
  1764
    "Scan.succeed (Thm.rule_attribute (K Drule.export_without_context))"
wenzelm@55152
  1765
wenzelm@55001
  1766
* More thorough check of proof context for goal statements and
wenzelm@55006
  1767
attributed fact expressions (concerning background theory, declared
wenzelm@55006
  1768
hyps).  Potential INCOMPATIBILITY, tools need to observe standard
wenzelm@55006
  1769
context discipline.  See also Assumption.add_assumes and the more
wenzelm@55006
  1770
primitive Thm.assume_hyps.
wenzelm@55001
  1771
wenzelm@55108
  1772
* Inner syntax token language allows regular quoted strings "..."
wenzelm@55108
  1773
(only makes sense in practice, if outer syntax is delimited
wenzelm@57452
  1774
differently, e.g. via cartouches).
wenzelm@57452
  1775
wenzelm@57504
  1776
* Command 'print_term_bindings' supersedes 'print_binds' for clarity,
wenzelm@57504
  1777
but the latter is retained some time as Proof General legacy.
wenzelm@57504
  1778
wenzelm@57452
  1779
* Code generator preprocessor: explicit control of simp tracing on a
wenzelm@57452
  1780
per-constant basis.  See attribute "code_preproc".

* Renamed command 'enriched_type' to 'functor'. INCOMPATIBILITY.
wenzelm@57504
  1810
wenzelm@57504
  1811
* The symbol "\<newline>" may be used within char or string literals
wenzelm@57504

* Simplifier: Enhanced solver of preconditions of rewrite rules can
wenzelm@57452
  1817
now deal with conjunctions.  For help with converting proofs, the old
wenzelm@57452
  1818
behaviour of the simplifier can be restored like this: declare/using
wenzelm@57452
  1819
[[simp_legacy_precond]].  This configuration option will disappear
wenzelm@57452
  1820
again in the future.  INCOMPATIBILITY.

wenzelm@57508
  1974
* New internal SAT solver "cdclite" that produces models and proof
wenzelm@57508
  1975
traces.  This solver replaces the internal SAT solvers "enumerate" and
wenzelm@57508
  1976
"dpll".  Applications that explicitly used one of these two SAT
wenzelm@57508
  1977
solvers should use "cdclite" instead. In addition, "cdclite" is now
wenzelm@57508
  1978
the default SAT solver for the "sat" and "satx" proof methods and
wenzelm@57508
  1979
corresponding tactics; the old default can be restored using "declare

  1983
"SMT2", uses SMT-LIB 2 and supports recent versions of Z3 (e.g.,
wenzelm@57508
  1984
4.3). The new proof method is called "smt2". CVC3 and CVC4 are also
wenzelm@57508
  1985
supported as oracles. Yices is no longer supported, because no version
wenzelm@57508
  1986
of the solver can handle both SMT-LIB 2 and quantifiers.
wenzelm@57508
  1987
wenzelm@57508
  1988
* Activation of Z3 now works via "z3_non_commercial" system option
wenzelm@57508

wenzelm@57508
  1990
"Z3_NON_COMMERCIAL".  The option can be edited in Isabelle/jEdit menu

  - Z3 can now produce Isar proofs.
wenzelm@57508
  1995
  - MaSh overhaul:
blanchet@57532
  1996
    . New SML-based learning algorithms eliminate the dependency on
wenzelm@57508
  1997
      Python and increase performance and reliability.
wenzelm@57508
  1998
    . MaSh and MeSh are now used by default together with the
wenzelm@57508
  1999
      traditional MePo (Meng-Paulson) relevance filter. To disable
wenzelm@57508
  2000
      MaSh, set the "MaSh" system option in Isabelle/jEdit Plugin
wenzelm@57508
  2001
      Options / Isabelle / General to "none".
wenzelm@57508

wenzelm@57508
  2011
wenzelm@57508
  2012
* Nitpick:
wenzelm@57508
  2013
  - Fixed soundness bug whereby mutually recursive datatypes could
wenzelm@57508
  2014
    take infinite values.
wenzelm@57508
  2015
  - Fixed soundness bug with low-level number functions such as
wenzelm@57508
  2016
    "Abs_Integ" and "Rep_Integ".
wenzelm@57508
  2017
  - Removed "std" option.
wenzelm@57508
  2018
  - Renamed "show_datatypes" to "show_types" and "hide_datatypes" to

  2019
    "hide_types".
wenzelm@57508
  2020
wenzelm@57508
  2021

(full_types)' instead. INCOMPATIBILITY.
wenzelm@57508
  2023
wenzelm@57508

  2025
wenzelm@57508
  2026
* Adjustion of INF and SUP operations:
wenzelm@57508
  2027
  - Elongated constants INFI and SUPR to INFIMUM and SUPREMUM.
wenzelm@57508
  2028
  - Consolidated theorem names containing INFI and SUPR: have INF and
wenzelm@57508
  2029
    SUP instead uniformly.
wenzelm@57508
  2030
  - More aggressive normalization of expressions involving INF and Inf
wenzelm@57508
  2031
    or SUP and Sup.
wenzelm@57508
  2032
  - INF_image and SUP_image do not unfold composition.
wenzelm@57508
  2033
  - Dropped facts INF_comp, SUP_comp.
wenzelm@57508
  2034
  - Default congruence rules strong_INF_cong and strong_SUP_cong, with
wenzelm@57508
  2035
    simplifier implication in premises.  Generalize and replace former
wenzelm@57508

* Subtle change of semantics of Thm.eq_thm: theory stamps are not
wenzelm@57504
  2580
compared (according to Thm.thm_ord), but assumed to be covered by the
wenzelm@57504

wenzelm@57504

branches of the theory graph usually coincides (e.g. relevant for
wenzelm@57504

theory merge).  Note that the softer Thm.eq_thm_prop is often more

  2604
wenzelm@56281
  2605
* Renamed configuration option "ML_trace" to "ML_source_trace". Minor
wenzelm@56281
  2606
INCOMPATIBILITY.
wenzelm@56281
  2607
wenzelm@56281
  2608
* Configuration option "ML_print_depth" controls the pretty-printing
wenzelm@56281
  2609
depth of the ML compiler within the context.  The old print_depth in
wenzelm@56285
  2610
ML is still available as default_print_depth, but rarely used.  Minor
wenzelm@56285
  2611
INCOMPATIBILITY.
wenzelm@56279
  2612
wenzelm@54449
  2613
* Toplevel function "use" refers to raw ML bootstrap environment,
wenzelm@54449
  2614
without Isar context nor antiquotations.  Potential INCOMPATIBILITY.
wenzelm@54449
  2615
Note that 'ML_file' is the canonical command to load ML files into the
wenzelm@54449
  2616
formal context.
wenzelm@54449
  2617
wenzelm@56205
  2618
* Simplified programming interface to define ML antiquotations, see
wenzelm@56205
  2619
structure ML_Antiquotation.  Minor INCOMPATIBILITY.
wenzelm@56069
  2620
wenzelm@56071
  2621
* ML antiquotation @{here} refers to its source position, which is
wenzelm@56071
  2622
occasionally useful for experimentation and diagnostic purposes.
wenzelm@56071
  2623
wenzelm@56135
  2624
* ML antiquotation @{path} produces a Path.T value, similarly to
wenzelm@56135
  2625
Path.explode, but with compile-time check against the file-system and
wenzelm@56135
  2626
some PIDE markup.  Note that unlike theory source, ML does not have a
wenzelm@56135
  2627
well-defined master directory, so an absolute symbolic path
wenzelm@56135
  2628
specification is usually required, e.g. "~~/src/HOL".
wenzelm@56135
  2629
wenzelm@56399
  2630
* ML antiquotation @{print} inlines a function to print an arbitrary
wenzelm@56399
  2631
ML value, which is occasionally useful for diagnostic or demonstration
wenzelm@56399
  2632
purposes.

*** System ***
wenzelm@54683
  2636
wenzelm@57443
  2637
* Proof General with its traditional helper scripts is now an optional
wenzelm@57504
  2638
Isabelle component, e.g. see ProofGeneral-4.2-2 from the Isabelle
wenzelm@57504
  2639
component repository http://isabelle.in.tum.de/components/.  Note that
wenzelm@57504
  2640
the "system" manual provides general explanations about add-on
wenzelm@57504
  2641
components, especially those that are not bundled with the release.
wenzelm@57443
  2642
wenzelm@56439
  2643
* The raw Isabelle process executable has been renamed from
wenzelm@56439
  2644
"isabelle-process" to "isabelle_process", which conforms to common
wenzelm@56439
  2645
shell naming conventions, and allows to define a shell function within
wenzelm@56439
  2646
the Isabelle environment to avoid dynamic path lookup.  Rare
wenzelm@57504
  2647
incompatibility for old tools that do not use the ISABELLE_PROCESS
wenzelm@57504
  2648
settings variable.
wenzelm@56439
  2649
wenzelm@57439
  2650
* Former "isabelle tty" has been superseded by "isabelle console",
wenzelm@57439
  2651
with implicit build like "isabelle jedit", and without the mostly
wenzelm@57439
  2652
obsolete Isar TTY loop.
wenzelm@57439
  2653
wenzelm@57452
  2654
* Simplified "isabelle display" tool.  Settings variables DVI_VIEWER
wenzelm@57452
  2655
and PDF_VIEWER now refer to the actual programs, not shell
wenzelm@57452
  2656
command-lines.  Discontinued option -c: invocation may be asynchronous
wenzelm@57452
  2657
via desktop environment, without any special precautions.  Potential
wenzelm@57452
  2658
INCOMPATIBILITY with ambitious private settings.
wenzelm@57452
  2659
wenzelm@57413
  2660
* Removed obsolete "isabelle unsymbolize".  Note that the usual format
wenzelm@57413
  2661
for email communication is the Unicode rendering of Isabelle symbols,
wenzelm@57413
  2662
as produced by Isabelle/jEdit, for example.
wenzelm@57413
  2663
wenzelm@57452
  2664
* Removed obsolete tool "wwwfind". Similar functionality may be
wenzelm@57452
  2665
integrated into Isabelle/jEdit eventually.
wenzelm@57452
  2666
wenzelm@57452
  2667
* Improved 'display_drafts' concerning desktop integration and
wenzelm@57452
  2668
repeated invocation in PIDE front-end: re-use single file
wenzelm@57452
  2669
$ISABELLE_HOME_USER/tmp/drafts.pdf and corresponding views.
wenzelm@57084
  2670
wenzelm@57452
  2671
* Session ROOT specifications require explicit 'document_files' for
wenzelm@57452
  2672
robust dependencies on LaTeX sources.  Only these explicitly given
wenzelm@57452
  2673
files are copied to the document output directory, before document
wenzelm@57452
  2674
processing is started.
wenzelm@57452
  2675
wenzelm@57504
  2676
* Windows: support for regular TeX installation (e.g. MiKTeX) instead
wenzelm@57504
  2677
of TeX Live from Cygwin.

*** Prover IDE -- Isabelle/Scala/jEdit ***
wenzelm@54639
  2685
wenzelm@54639
  2686
* More robust editing of running commands with internal forks,
wenzelm@54639
  2687
e.g. non-terminating 'by' steps.
wenzelm@54639
  2688
wenzelm@54641
  2689
* More relaxed Sledgehammer panel: avoid repeated application of query
wenzelm@54641
  2690
after edits surrounding the command location.
wenzelm@54641
  2691
wenzelm@54648
  2692
* More status information about commands that are interrupted
wenzelm@54648
  2693
accidentally (via physical event or Poly/ML runtime system signal,
wenzelm@54648
  2694
e.g. out-of-memory).

* More robust termination of external processes managed by
wenzelm@54664
  2700
Isabelle/ML: support cancellation of tasks within the range of
wenzelm@54664
  2701
milliseconds, as required for PIDE document editing with automatically
wenzelm@54664
  2702
tried tools (e.g. Sledgehammer).
wenzelm@54653
  2703
wenzelm@54648
  2704
* Reactivated Isabelle/Scala kill command for external processes on
wenzelm@54648
  2705
Mac OS X, which was accidentally broken in Isabelle2013-1 due to a
wenzelm@54648
  2706
workaround for some Debian/Ubuntu Linux versions from 2013.
