*** General ***
wenzelm@62440
    11
wenzelm@62440
    12
* New symbol \<circle>, e.g. for temporal operator.

*** Isar ***
wenzelm@62312
    16
wenzelm@62312
    17
* Command '\<proof>' is an alias for 'sorry', with different
wenzelm@62312
    18
typesetting. E.g. to produce proof holes in examples and documentation.

*** HOL ***
blanchet@62327
    22
blanchet@62327
    23
* (Co)datatype package:
traytel@62332
    24
  - the predicator :: ('a => bool) => 'a F => bool is now a first-class
traytel@62332
    25
    citizen in bounded natural functors
blanchet@62327
    26
  - "primrec" now allows nested calls through the predicator in addition
blanchet@62327
    27
    to the map function.
traytel@62332
    28
  - "bnf" automatically discharges reflexive proof obligations
traytel@62332
    29
    "bnf" outputs a slightly modified proof obligation expressing rel in
traytel@62332
    30
       terms of map and set
traytel@62332
    31
       (not giving a specification for rel makes this one reflexive)
traytel@62332
    32
    "bnf" outputs a new proof obligation expressing pred in terms of set
traytel@62332
    33
       (not giving a specification for pred makes this one reflexive)
traytel@62332
    34
    INCOMPATIBILITY: manual "bnf" declarations may need adjustment
blanchet@62335
    35
  - Renamed lemmas:
blanchet@62335
    36
      rel_prod_apply ~> rel_prod_inject
blanchet@62335
    37
      pred_prod_apply ~> pred_prod_inject
blanchet@62335
    38
    INCOMPATIBILITY.
blanchet@62327
    39
wenzelm@62407
    40
* Renamed split_if -> if_split and split_if_asm -> if_split_asm to
wenzelm@62407
    41
resemble the f.split naming convention, INCOMPATIBILITY.
nipkow@62396
    42
haftmann@62430
    43
* Multiset membership is now expressed using set_mset rather than count.
haftmann@62430
    44
ASCII infix syntax ":#" has been discontinued.
haftmann@62430
    45
haftmann@62430
    46
  - Expressions "count M a > 0" and similar simplify to membership
haftmann@62430
    47
    by default.
haftmann@62430
    48
haftmann@62430
    49
  - Converting between "count M a = 0" and non-membership happens using
haftmann@62430
    50
    equations count_eq_zero_iff and not_in_iff.
haftmann@62430
    51
haftmann@62430
    52
  - Rules count_inI and in_countE obtain facts of the form
haftmann@62430
    53
    "count M a = n" from membership.
haftmann@62430
    54
haftmann@62430
    55
  - Rules count_in_diffI and in_diff_countE obtain facts of the form
haftmann@62430
    56
    "count M a = n + count N a" from membership on difference sets.
haftmann@62430
    57
haftmann@62430
    58
INCOMPATIBILITY.
haftmann@62430
    59
haftmann@62343
    60
* Compound constants INFIMUM and SUPREMUM are mere abbreviations now.
haftmann@62343
    61
INCOMPATIBILITY.
haftmann@62343
    62
lp15@62408
    63
* More complex analysis including Cauchy's inequality, Liouville theorem,
lp15@62408
    64
open mapping theorem, maximum modulus principle, Schwarz Lemma.
lp15@62408
    65
haftmann@62358
    66
* "Gcd (f ` A)" and "Lcm (f ` A)" are printed with optional
haftmann@62358
    67
comprehension-like syntax analogously to "Inf (f ` A)" and "Sup (f ` A)".
haftmann@62358
    68
haftmann@62345
    69
* Class semiring_Lcd merged into semiring_Gcd.  INCOMPATIBILITY.
haftmann@62345
    70
hoelzl@62376
    71
* The type class ordered_comm_monoid_add is now called
hoelzl@62376
    72
ordered_cancel_comm_monoid_add. A new type class ordered_comm_monoid_add is
hoelzl@62376
    73
introduced as the combination of ordered_ab_semigroup_add + comm_monoid_add.
hoelzl@62376
    74
INCOMPATIBILITY.
hoelzl@62376
    75
hoelzl@62376
    76
* Introduced the type classes canonically_ordered_comm_monoid_add and dioid.
hoelzl@62376
    77
hoelzl@62376
    78
* Added topological_monoid
hoelzl@62376
    79
haftmann@62352
    80
* Library/Polynomial.thy contains also derivation of polynomials
haftmann@62352
    81
but not gcd/lcm on polynomials over fields.  This has been moved
haftmann@62352
    82
to a separate theory Library/Polynomial_GCD_euclidean.thy, to
haftmann@62352
    83
pave way for a possible future different type class instantiation
haftmann@62352
    84
for polynomials over factorial rings.  INCOMPATIBILITY.
haftmann@62352
    85
haftmann@62348
    86
* Dropped various legacy fact bindings, whose replacements are often
haftmann@62348
    87

*** System ***
wenzelm@62354
   180
wenzelm@62416
   181
* The Isabelle system environment always ensures that the main
wenzelm@62416
   182
executables are found within the PATH: isabelle, isabelle_process,
wenzelm@62416
   183
isabelle_scala_script.
wenzelm@62416
   184
wenzelm@62451
   185
* The somewhat pointless command-line tool "isabelle yxml" has been
wenzelm@62451
   186
discontinued. INCOMPATIBILITY, use operations from the modules "XML" and
wenzelm@62451
   187
"YXML" in Isabelle/ML or Isabelle/Scala.
wenzelm@62451
   188
wenzelm@62354
   189
* SML/NJ is no longer supported.
wenzelm@62354
   190
wenzelm@62354
   191
wenzelm@62031
   192
New in Isabelle2016 (February 2016)
wenzelm@62016
   193
-----------------------------------
wenzelm@60138
   194
wenzelm@61337
   195
*** General ***
wenzelm@61337
   196
wenzelm@62168
   197
* Eisbach is now based on Pure instead of HOL. Objects-logics may import
wenzelm@62168
   198
either the theory ~~/src/HOL/Eisbach/Eisbach (for HOL etc.) or
wenzelm@62168
   199
~~/src/HOL/Eisbach/Eisbach_Old_Appl_Syntax (for FOL, ZF etc.). Note that
wenzelm@62168
   200
the HOL-Eisbach session located in ~~/src/HOL/Eisbach/ contains further
wenzelm@62168
   201
examples that do require HOL.
wenzelm@62168
   202
wenzelm@62157
   203
* Better resource usage on all platforms (Linux, Windows, Mac OS X) for
wenzelm@62157
   204
both Isabelle/ML and Isabelle/Scala.  Slightly reduced heap space usage.
wenzelm@62157
   205
wenzelm@62017
   206
* Former "xsymbols" syntax with Isabelle symbols is used by default,
wenzelm@62017
   207
without any special print mode. Important ASCII replacement syntax
wenzelm@62017
   208
remains available under print mode "ASCII", but less important syntax
wenzelm@62017
   209
has been removed (see below).
wenzelm@62017
   210
wenzelm@62109
   211
* Support for more arrow symbols, with rendering in LaTeX and Isabelle
wenzelm@62109
   212
fonts: \<Lleftarrow> \<Rrightarrow> \<longlongleftarrow> \<longlongrightarrow> \<longlonglongleftarrow> \<longlonglongrightarrow>.
wenzelm@62017
   213
wenzelm@62108
   214
* Special notation \<struct> for the first implicit 'structure' in the
wenzelm@62108
   215
context has been discontinued. Rare INCOMPATIBILITY, use explicit
wenzelm@62108
   216
structure name instead, notably in indexed notation with block-subscript
wenzelm@62108
   217
(e.g. \<odot>\<^bsub>A\<^esub>).
wenzelm@62108
   218
wenzelm@62108
   219
* The glyph for \<diamond> in the IsabelleText font now corresponds better to its
wenzelm@62108
   220
counterpart \<box> as quantifier-like symbol. A small diamond is available as
wenzelm@62108
   221
\<diamondop>; the old symbol \<struct> loses this rendering and any special
wenzelm@62108
   222
meaning.
wenzelm@62108
   223
wenzelm@62017
   224
* Syntax for formal comments "-- text" now also supports the symbolic
wenzelm@62017
   225
form "\<comment> text". Command-line tool "isabelle update_cartouches -c" helps
wenzelm@62017
   226
to update old sources.
wenzelm@62017
   227
wenzelm@61337
   228
* Toplevel theorem statements have been simplified as follows:
wenzelm@61337
   229
wenzelm@61337
   230
  theorems             ~>  lemmas
wenzelm@61337
   231
  schematic_lemma      ~>  schematic_goal
wenzelm@61337
   232
  schematic_theorem    ~>  schematic_goal
wenzelm@61337
   233
  schematic_corollary  ~>  schematic_goal
wenzelm@61337
   234
wenzelm@61337
   235
Command-line tool "isabelle update_theorems" updates theory sources
wenzelm@61337
   236
accordingly.
wenzelm@61337
   237
wenzelm@61338
   238
* Toplevel theorem statement 'proposition' is another alias for
wenzelm@61338
   239
'theorem'.
wenzelm@61338
   240
wenzelm@62169
   241
* The old 'defs' command has been removed (legacy since Isabelle2014).
wenzelm@62169
   242
INCOMPATIBILITY, use regular 'definition' instead. Overloaded and/or
wenzelm@62169
   243
deferred definitions require a surrounding 'overloading' block.

   246
*** Prover IDE -- Isabelle/Scala/jEdit ***
wenzelm@60610
   247
wenzelm@60986
   248
* IDE support for the source-level debugger of Poly/ML, to work with
wenzelm@62253
   249
Isabelle/ML and official Standard ML. Option "ML_debugger" and commands
wenzelm@62253
   250
'ML_file_debug', 'ML_file_no_debug', 'SML_file_debug',
wenzelm@62253
   251
'SML_file_no_debug' control compilation of sources with or without
wenzelm@62253
   252
debugging information. The Debugger panel allows to set breakpoints (via
wenzelm@62253
   253
context menu), step through stopped threads, evaluate local ML
wenzelm@62253
   254
expressions etc. At least one Debugger view needs to be active to have
wenzelm@62253
   255
any effect on the running ML program.
wenzelm@60984
   256
wenzelm@61804
   257
* The State panel manages explicit proof state output, with dynamic
wenzelm@61804
   258
auto-update according to cursor movement. Alternatively, the jEdit
wenzelm@61804
   259
action "isabelle.update-state" (shortcut S+ENTER) triggers manual
wenzelm@61804
   260
update.
wenzelm@61729
   261
wenzelm@61729
   262
* The Output panel no longer shows proof state output by default, to
wenzelm@61729
   263
avoid GUI overcrowding. INCOMPATIBILITY, use the State panel instead or
wenzelm@61729
   264
enable option "editor_output_state".
wenzelm@61215
   265
wenzelm@61804
   266
* The text overview column (status of errors, warnings etc.) is updated
wenzelm@61804
   267
asynchronously, leading to much better editor reactivity. Moreover, the
wenzelm@61804
   268
full document node content is taken into account. The width of the
wenzelm@61804
   269
column is scaled according to the main text area font, for improved
wenzelm@61804
   270
visibility.
wenzelm@61804
   271
wenzelm@61804
   272
* The main text area no longer changes its color hue in outdated
wenzelm@61804
   273
situations. The text overview column takes over the role to indicate
wenzelm@61804
   274
unfinished edits in the PIDE pipeline. This avoids flashing text display
wenzelm@61804
   275
due to ad-hoc updates by auxiliary GUI components, such as the State
wenzelm@61804
   276
panel.
wenzelm@61804
   277
wenzelm@62254
   278
* Slightly improved scheduling for urgent print tasks (e.g. command
wenzelm@62254
   279
state output, interactive queries) wrt. long-running background tasks.
wenzelm@62017
   280
wenzelm@62017
   281
* Completion of symbols via prefix of \<name> or \<^name> or \name is
wenzelm@62017
   282
always possible, independently of the language context. It is never
wenzelm@62017
   283
implicit: a popup will show up unconditionally.
wenzelm@62017
   284
wenzelm@62017
   285
* Additional abbreviations for syntactic completion may be specified in
wenzelm@62017
   286
$ISABELLE_HOME/etc/abbrevs and $ISABELLE_HOME_USER/etc/abbrevs, with
wenzelm@62017
   287
support for simple templates using ASCII 007 (bell) as placeholder.
wenzelm@62017
   288
wenzelm@62234
   289
* Symbols \<oplus>, \<Oplus>, \<otimes>, \<Otimes>, \<odot>, \<Odot>, \<ominus>, \<oslash> no longer provide abbreviations for
wenzelm@62234
   290
completion like "+o", "*o", ".o" etc. -- due to conflicts with other
wenzelm@62234
   291
ASCII syntax. INCOMPATIBILITY, use plain backslash-completion or define
wenzelm@62234
   292
suitable abbreviations in $ISABELLE_HOME_USER/etc/abbrevs.
wenzelm@62234
   293
wenzelm@61483
   294
* Action "isabelle-emph" (with keyboard shortcut C+e LEFT) controls
wenzelm@61483
   295
emphasized text style; the effect is visible in document output, not in
wenzelm@61483
   296
the editor.
wenzelm@61483
   297
wenzelm@61483
   298
* Action "isabelle-reset" now uses keyboard shortcut C+e BACK_SPACE,
wenzelm@61483
   299
instead of former C+e LEFT.
wenzelm@61483
   300
wenzelm@61512
   301
* The command-line tool "isabelle jedit" and the isabelle.Main
wenzelm@62027
   302
application wrapper treat the default $USER_HOME/Scratch.thy more
wenzelm@61512
   303
uniformly, and allow the dummy file argument ":" to open an empty buffer
wenzelm@61512
   304
instead.
wenzelm@61512
   305
wenzelm@62017
   306
* New command-line tool "isabelle jedit_client" allows to connect to an
wenzelm@62017
   307
already running Isabelle/jEdit process. This achieves the effect of
wenzelm@62017
   308
single-instance applications seen on common GUI desktops.
wenzelm@62017
   309
wenzelm@61530
   310
* The default look-and-feel for Linux is the traditional "Metal", which
wenzelm@61530
   311
works better with GUI scaling for very high-resolution displays (e.g.
wenzelm@61530
   312
4K). Moreover, it is generally more robust than "Nimbus".
wenzelm@61530
   313
wenzelm@62163
   314
* Update to jedit-5.3.0, with improved GUI scaling and support of
wenzelm@62163
   315
high-resolution displays (e.g. 4K).
wenzelm@62163
   316
wenzelm@62034
   317
* The main Isabelle executable is managed as single-instance Desktop
wenzelm@62034
   318
application uniformly on all platforms: Linux, Windows, Mac OS X.

*** Document preparation ***
wenzelm@61405
   322
wenzelm@62017
   323
* Commands 'paragraph' and 'subparagraph' provide additional section
wenzelm@62017
   324
headings. Thus there are 6 levels of standard headings, as in HTML.
wenzelm@62017
   325
wenzelm@62017
   326
* Command 'text_raw' has been clarified: input text is processed as in
wenzelm@62017
   327
'text' (with antiquotations and control symbols). The key difference is
wenzelm@62017
   328
the lack of the surrounding isabelle markup environment in output.
wenzelm@62017
   329
wenzelm@62017
   330
* Text is structured in paragraphs and nested lists, using notation that
wenzelm@62017
   331
is similar to Markdown. The control symbols for list items are as
wenzelm@62017
   332
follows:
wenzelm@62017
   333
wenzelm@62017
   334
  \<^item>  itemize
wenzelm@62017
   335
  \<^enum>  enumerate
wenzelm@62017
   336
  \<^descr>  description
wenzelm@62017
   337
wenzelm@61491
   338
* There is a new short form for antiquotations with a single argument
wenzelm@61491
   339
that is a cartouche: \<^name>\<open>...\<close> is equivalent to @{name \<open>...\<close>} and
wenzelm@61595
   340
\<open>...\<close> without control symbol is equivalent to @{cartouche \<open>...\<close>}.
wenzelm@61595
   341
\<^name> without following cartouche is equivalent to @{name}. The
wenzelm@61501
   342
standard Isabelle fonts provide glyphs to render important control
wenzelm@61501
   343
symbols, e.g. "\<^verbatim>", "\<^emph>", "\<^bold>".
wenzelm@61491
   344
wenzelm@61595
   345
* Antiquotations @{noindent}, @{smallskip}, @{medskip}, @{bigskip} with
wenzelm@61595
   346
corresponding control symbols \<^noindent>, \<^smallskip>, \<^medskip>, \<^bigskip> specify spacing formally, using
wenzelm@61595
   347
standard LaTeX macros of the same names.
wenzelm@61595
   348
wenzelm@61491
   349
* Antiquotation @{cartouche} in Isabelle/Pure is the same as @{text}.
wenzelm@61491
   350
Consequently, \<open>...\<close> without any decoration prints literal quasi-formal
wenzelm@61492
   351
text. Command-line tool "isabelle update_cartouches -t" helps to update
wenzelm@61492
   352
old sources, by approximative patching of the content of string and
wenzelm@61492
   353
cartouche tokens seen in theory sources.
wenzelm@61491
   354
wenzelm@61491
   355
* The @{text} antiquotation now ignores the antiquotation option
wenzelm@61491
   356
"source". The given text content is output unconditionally, without any
wenzelm@61491
   357
surrounding quotes etc. Subtle INCOMPATIBILITY, put quotes into the
wenzelm@61494
   358
argument where they are really intended, e.g. @{text \<open>"foo"\<close>}. Initial
wenzelm@61494
   359
or terminal spaces are ignored.
wenzelm@61491
   360
wenzelm@62017
   361
* Antiquotations @{emph} and @{bold} output LaTeX source recursively,
wenzelm@62017
   362
adding appropriate text style markup. These may be used in the short
wenzelm@62017
   363
form \<^emph>\<open>...\<close> and \<^bold>\<open>...\<close>.
wenzelm@62017
   364
wenzelm@62017
   365
* Document antiquotation @{footnote} outputs LaTeX source recursively,
wenzelm@62017
   366
marked as \footnote{}. This may be used in the short form \<^footnote>\<open>...\<close>.
wenzelm@62017
   367
wenzelm@62017
   368
* Antiquotation @{verbatim [display]} supports option "indent".
wenzelm@62017
   369
wenzelm@62017
   370
* Antiquotation @{theory_text} prints uninterpreted theory source text
wenzelm@62231
   371
(Isar outer syntax with command keywords etc.). This may be used in the
wenzelm@62231
   372
short form \<^theory_text>\<open>...\<close>. @{theory_text [display]} supports option "indent".
wenzelm@62017
   373
wenzelm@62017
   374
* Antiquotation @{doc ENTRY} provides a reference to the given
wenzelm@62017
   375
documentation, with a hyperlink in the Prover IDE.
wenzelm@62017
   376
wenzelm@62017
   377
* Antiquotations @{command}, @{method}, @{attribute} print checked
wenzelm@62017
   378
entities of the Isar language.
wenzelm@62017
   379
wenzelm@61471
   380
* HTML presentation uses the standard IsabelleText font and Unicode
wenzelm@61471
   381
rendering of Isabelle symbols like Isabelle/Scala/jEdit.  The former
wenzelm@61488
   382
print mode "HTML" loses its special meaning.

*** Isar ***
wenzelm@60406
   386
wenzelm@62205
   387
* Local goals ('have', 'show', 'hence', 'thus') allow structured rule
wenzelm@62205
   388
statements like fixes/assumes/shows in theorem specifications, but the
wenzelm@62205
   389
notation is postfix with keywords 'if' (or 'when') and 'for'. For
wenzelm@60555
   390
example:
wenzelm@60414
   391
wenzelm@60414
   392
  have result: "C x y"
wenzelm@60414
   393
    if "A x" and "B y"
wenzelm@60414
   394
    for x :: 'a and y :: 'a
wenzelm@60414
   395
    <proof>
wenzelm@60414
   396
wenzelm@60449
   397
The local assumptions are bound to the name "that". The result is
wenzelm@60449
   398
exported from context of the statement as usual. The above roughly
wenzelm@60414
   399
corresponds to a raw proof block like this:
wenzelm@60414
   400
wenzelm@60414
   401
  {
wenzelm@60414
   402
    fix x :: 'a and y :: 'a
wenzelm@60449
   403
    assume that: "A x" "B y"
wenzelm@60414
   404
    have "C x y" <proof>
wenzelm@60414
   405
  }
wenzelm@60414
   406
  note result = this
wenzelm@60406
   407
wenzelm@60555
   408
The keyword 'when' may be used instead of 'if', to indicate 'presume'
wenzelm@60555
   409
instead of 'assume' above.
wenzelm@60555
   410
wenzelm@61733
   411
* Assumptions ('assume', 'presume') allow structured rule statements
wenzelm@61733
   412
using 'if' and 'for', similar to 'have' etc. above. For example:
wenzelm@61658
   413
wenzelm@61658
   414
  assume result: "C x y"
wenzelm@61658
   415
    if "A x" and "B y"
wenzelm@61658
   416
    for x :: 'a and y :: 'a
wenzelm@61658
   417
wenzelm@61658
   418
This assumes "\<And>x y::'a. A x \<Longrightarrow> B y \<Longrightarrow> C x y" and produces a general
wenzelm@61658
   419
result as usual: "A ?x \<Longrightarrow> B ?y \<Longrightarrow> C ?x ?y".
wenzelm@61658
   420
wenzelm@61658
   421
Vacuous quantification in assumptions is omitted, i.e. a for-context
wenzelm@61658
   422
only effects propositions according to actual use of variables. For
wenzelm@61658
   423
example:
wenzelm@61658
   424
wenzelm@61658
   425
  assume "A x" and "B y" for x and y
wenzelm@61658
   426
wenzelm@61658
   427
is equivalent to:
wenzelm@61658
   428
wenzelm@61658
   429
  assume "\<And>x. A x" and "\<And>y. B y"
wenzelm@61658
   430
wenzelm@60595
   431
* The meaning of 'show' with Pure rule statements has changed: premises
wenzelm@60595
   432
are treated in the sense of 'assume', instead of 'presume'. This means,
wenzelm@62205
   433
a goal like "\<And>x. A x \<Longrightarrow> B x \<Longrightarrow> C x" can be solved completely as
wenzelm@62205
   434
follows:
wenzelm@60595
   435
wenzelm@60595
   436
  show "\<And>x. A x \<Longrightarrow> B x \<Longrightarrow> C x"
wenzelm@60595
   437
wenzelm@60595
   438
or:
wenzelm@60595
   439
wenzelm@60595
   440
  show "C x" if "A x" "B x" for x
wenzelm@60595
   441
wenzelm@60595
   442
Rare INCOMPATIBILITY, the old behaviour may be recovered as follows:
wenzelm@60595
   443
wenzelm@60595
   444
  show "C x" when "A x" "B x" for x
wenzelm@60595
   445
wenzelm@60459
   446
* New command 'consider' states rules for generalized elimination and
wenzelm@60459
   447
case splitting. This is like a toplevel statement "theorem obtains" used
wenzelm@60459
   448
within a proof body; or like a multi-branch 'obtain' without activation
wenzelm@60459
   449
of the local context elements yet.
wenzelm@60459
   450
wenzelm@60455
   451
* Proof method "cases" allows to specify the rule as first entry of
wenzelm@60455
   452
chained facts.  This is particularly useful with 'consider':
wenzelm@60455
   453
wenzelm@60455
   454
  consider (a) A | (b) B | (c) C <proof>
wenzelm@60455
   455
  then have something
wenzelm@60455
   456
  proof cases
wenzelm@60455
   457
    case a
wenzelm@60455
   458
    then show ?thesis <proof>
wenzelm@60455
   459
  next
wenzelm@60455
   460
    case b
wenzelm@60455
   461
    then show ?thesis <proof>
wenzelm@60455
   462
  next
wenzelm@60455
   463
    case c
wenzelm@60455

    then show ?thesis <proof>
wenzelm@60455
   465
  qed
wenzelm@60455
   466
wenzelm@60565
   467
* Command 'case' allows fact name and attribute specification like this:
wenzelm@60565
   468
wenzelm@60565
   469
  case a: (c xs)
wenzelm@60565
   470
  case a [attributes]: (c xs)
wenzelm@60565
   471
wenzelm@60565
   472
Facts that are introduced by invoking the case context are uniformly
wenzelm@60565
   473
qualified by "a"; the same name is used for the cumulative fact. The old
wenzelm@60565
   474
form "case (c xs) [attributes]" is no longer supported. Rare
wenzelm@60565
   475
INCOMPATIBILITY, need to adapt uses of case facts in exotic situations,
wenzelm@60565
   476
and always put attributes in front.
wenzelm@60565
   477
wenzelm@60618
   478
* The standard proof method of commands 'proof' and '..' is now called
wenzelm@60618
   479
"standard" to make semantically clear what it is; the old name "default"
wenzelm@60618
   480
is still available as legacy for some time. Documentation now explains
wenzelm@60618
   481
'..' more accurately as "by standard" instead of "by rule".
wenzelm@60618
   482
wenzelm@62017
   483
* Nesting of Isar goal structure has been clarified: the context after
wenzelm@62017
   484
the initial backwards refinement is retained for the whole proof, within
wenzelm@62017
   485
all its context sections (as indicated via 'next'). This is e.g.
wenzelm@62017
   486
relevant for 'using', 'including', 'supply':
wenzelm@62017
   487
wenzelm@62017
   488
  have "A \<and> A" if a: A for A
wenzelm@62017
   489
    supply [simp] = a
wenzelm@62017
   490
  proof
wenzelm@62017
   491
    show A by simp
wenzelm@62017

wenzelm@62017

   494
  qed
wenzelm@62017
   495
wenzelm@62017
   496
* Command 'obtain' binds term abbreviations (via 'is' patterns) in the
wenzelm@62017
   497
proof body as well, abstracted over relevant parameters.
wenzelm@62017
   498
wenzelm@62017
   499
* Improved type-inference for theorem statement 'obtains': separate
wenzelm@62017
   500
parameter scope for of each clause.
wenzelm@62017
   501
wenzelm@62017
   502
* Term abbreviations via 'is' patterns also work for schematic
wenzelm@62017
   503
statements: result is abstracted over unknowns.
wenzelm@62017
   504
wenzelm@60631
   505
* Command 'subgoal' allows to impose some structure on backward
wenzelm@60631
   506
refinements, to avoid proof scripts degenerating into long of 'apply'
wenzelm@60631
   507
sequences. Further explanations and examples are given in the isar-ref
wenzelm@60631
   508
manual.
wenzelm@60631
   509
wenzelm@62017
   510
* Command 'supply' supports fact definitions during goal refinement
wenzelm@62017
   511
('apply' scripts).
wenzelm@62017
   512
wenzelm@61166
   513
* Proof method "goal_cases" turns the current subgoals into cases within
wenzelm@61166
   514
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
   538
is marked as legacy, and will be removed eventually. The proof method
wenzelm@60617
   539
"goals" achieves a similar effect within regular Isar; often it can be
wenzelm@60617
   540
done more adequately by other means (e.g. 'consider').

of the command. Previously, for 'locale' and 'sublocale' the default was

optional ('?'). The old synatx '!' has been discontinued.

* More gentle suppression of syntax along locale morphisms while
wenzelm@62017
   560
printing terms. Previously 'abbreviation' and 'notation' declarations
wenzelm@62017
   561
would be suppressed for morphisms except term identity. Now
ballarin@61701
   562
'abbreviation' is also kept for morphims that only change the involved
wenzelm@62017
   563
parameters, and only 'notation' is suppressed. This can be of great help
wenzelm@62017
   564
when working with complex locale hierarchies, because proof states are
wenzelm@62017
   565
displayed much more succinctly. It also means that only notation needs
wenzelm@62017
   566
to be redeclared if desired, as illustrated by this example:
ballarin@61701
   567
ballarin@61701

  locale struct = fixes composition :: "'a => 'a => 'a" (infixl "\<cdot>" 65)

* The 'typedef' command has been upgraded from a partially checked
wenzelm@62017
   607
"axiomatization", to a full definitional specification that takes the
wenzelm@62017
   608
global collection of overloaded constant / type definitions into
wenzelm@62017
   609
account. Type definitions with open dependencies on overloaded
wenzelm@62017
   610
definitions need to be specified as "typedef (overloaded)". This
wenzelm@62017
   611
provides extra robustness in theory construction. Rare INCOMPATIBILITY.
wenzelm@62017
   612
wenzelm@62017
   613
* Qualification of various formal entities in the libraries is done more
wenzelm@62017
   614
uniformly via "context begin qualified definition ... end" instead of
wenzelm@62017
   615
old-style "hide_const (open) ...". Consequently, both the defined
wenzelm@62017
   616
constant and its defining fact become qualified, e.g. Option.is_none and
wenzelm@62017
   617
Option.is_none_def. Occasional INCOMPATIBILITY in applications.
wenzelm@62017

wenzelm@62017
   653
* Commands 'inductive' and 'inductive_set' work better when names for
wenzelm@62017
   654
intro rules are omitted: the "cases" and "induct" rules no longer
wenzelm@62017
   655
declare empty case_names, but no case_names at all. This allows to use
wenzelm@62017
   656
numbered cases in proofs, without requiring method "goal_cases".
wenzelm@62017
   657
wenzelm@62017

* Inductive definitions ('inductive', 'coinductive', etc.) expose
wenzelm@62017
   659
low-level facts of the internal construction only if the option
wenzelm@62093

wenzelm@62093
   669
of the internal construction only if the option "bnf_internals" is

   800
INCOMPATIBILITY.
haftmann@60516
   801
haftmann@60688
   802
* Class algebraic_semidom introduces common algebraic notions of
wenzelm@62017
   803
integral (semi)domains, particularly units. Although logically subsumed
wenzelm@62017
   804
by fields, is is not a super class of these in order not to burden
wenzelm@62017
   805
fields with notions that are trivial there.
wenzelm@62017
   806
wenzelm@62017
   807
* Class normalization_semidom specifies canonical representants for
wenzelm@62017

equivalence classes of associated elements in an integral (semi)domain.
wenzelm@62017
   809
This formalizes associated elements as well.

* Abstract specification of gcd/lcm operations in classes semiring_gcd,
wenzelm@62017
   812
semiring_Gcd, semiring_Lcd. Minor INCOMPATIBILITY: facts gcd_nat.commute
wenzelm@62017
   813
and gcd_int.commute are subsumed by gcd.commute, as well as
wenzelm@62017
   814
gcd_nat.assoc and gcd_int.assoc by gcd.assoc.
wenzelm@62017

   816
* Former constants Fields.divide (_ / _) and Divides.div (_ div _) are
wenzelm@62017
   817
logically unified to Rings.divide in syntactic type class Rings.divide,
wenzelm@62017
   818
with infix syntax (_ div _). Infix syntax (_ / _) for field division is
wenzelm@62017
   819
added later as abbreviation in class Fields.inverse. INCOMPATIBILITY,
wenzelm@62017
   820
instantiations must refer to Rings.divide rather than the former
wenzelm@62017
   821
separate constants, hence infix syntax (_ / _) is usually not available
wenzelm@62017
   822
during instantiation.
wenzelm@62017
   823
wenzelm@62017
   824
* New cancellation simprocs for boolean algebras to cancel complementary
wenzelm@62017
   825
terms for sup and inf. For example, "sup x (sup y (- x))" simplifies to
wenzelm@62017

   927
  profile_allocations   (*overall heap allocations*)
wenzelm@62017

   933
wenzelm@61922

* Pretty printing of Poly/ML compiler output in Isabelle has been
wenzelm@61922
   935
improved: proper treatment of break offsets and blocks with consistent
wenzelm@61922
   936
breaks.
wenzelm@61922
   937
wenzelm@61268
   938
* The auxiliary module Pure/display.ML has been eliminated. Its
wenzelm@61268
   939
elementary thm print operations are now in Pure/more_thm.ML and thus
wenzelm@61268
   940
called Thm.pretty_thm, Thm.string_of_thm etc. INCOMPATIBILITY.
wenzelm@61268
   941
wenzelm@61144
   942
* Simproc programming interfaces have been simplified:
wenzelm@61144
   943
Simplifier.make_simproc and Simplifier.define_simproc supersede various
wenzelm@61144
   944
forms of Simplifier.mk_simproc, Simplifier.simproc_global etc. Note that
wenzelm@61144
   945
term patterns for the left-hand sides are specified with implicitly
wenzelm@61144
   946
fixed variables, like top-level theorem statements. INCOMPATIBILITY.
wenzelm@61144
   947
wenzelm@60802

* Instantiation rules have been re-organized as follows:
wenzelm@60802
   949
wenzelm@60802
   950
  Thm.instantiate  (*low-level instantiation with named arguments*)
wenzelm@60802

  Drule.infer_instantiate  (*instantiation with type inference*)

   954
  Drule.infer_instantiate'  (*version with positional arguments*)
wenzelm@60802
   955
wenzelm@60802
   956
The LHS only requires variable specifications, instead of full terms.
wenzelm@60802
   957
Old cterm_instantiate is superseded by infer_instantiate.
wenzelm@60802
   958
INCOMPATIBILITY, need to re-adjust some ML names and types accordingly.
wenzelm@60802
   959
wenzelm@60793
   960
* Old tactic shorthands atac, rtac, etac, dtac, ftac have been
wenzelm@60793
   961
discontinued. INCOMPATIBILITY, use regular assume_tac, resolve_tac etc.
wenzelm@60793
   962
instead (with proper context).
wenzelm@60642
   963
wenzelm@60642
   964
* Thm.instantiate (and derivatives) no longer require the LHS of the
wenzelm@60642
   965
instantiation to be certified: plain variables are given directly.
wenzelm@60642
   966
wenzelm@60707
   967
* Subgoal.SUBPROOF and Subgoal.FOCUS combinators use anonymous
wenzelm@60707
   968
quasi-bound variables (like the Simplifier), instead of accidentally
wenzelm@60707
   969
named local fixes. This has the potential to improve stability of proof
wenzelm@60707
   970
tools, but can also cause INCOMPATIBILITY for tools that don't observe
wenzelm@60707
   971
the proof context discipline.
wenzelm@60707
   972
wenzelm@62017
   973
* Isar proof methods are based on a slightly more general type
wenzelm@62017
   974
context_tactic, which allows to change the proof context dynamically
wenzelm@62017
   975
(e.g. to update cases) and indicate explicit Seq.Error results. Former
wenzelm@62017
   976
METHOD_CASES is superseded by CONTEXT_METHOD; further combinators are

maintainability of proofs.
wenzelm@62017

  1019
is relevant both for Poly/ML and JVM processes.
wenzelm@61294
  1020
wenzelm@62017
  1021
* Poly/ML default platform architecture may be changed from 32bit to
wenzelm@62205
  1022
64bit via system option ML_system_64. A system restart (and rebuild) is
wenzelm@62205
  1023
required after change.
wenzelm@62017
  1024
wenzelm@62017
  1025
* Poly/ML 5.6 runs natively on x86-windows and x86_64-windows, which
wenzelm@62017
  1026
both allow larger heap space than former x86-cygwin.
wenzelm@62017
  1027
wenzelm@62157

  1039
'qualified' modifier to restrict name space accesses to the local scope,
wenzelm@59939

together with an attribute to maintain the content incrementally. This
wenzelm@59951
  1065
supersedes functor Named_Thms in Isabelle/ML, but with a subtle change

wenzelm@59569
  1074
theory context.
wenzelm@57941
  1075
wenzelm@58928
  1076
* Outer syntax commands are managed authentically within the theory
wenzelm@59569
  1077

wenzelm@58928
  1078
INCOMPATIBILITY, make sure that required theories are really imported.
wenzelm@58928
  1079
wenzelm@60116
  1080
* Historical command-line terminator ";" is no longer accepted (and
wenzelm@60116
  1081
already used differently in Isar). Minor INCOMPATIBILITY, use "isabelle
wenzelm@60116
  1082
update_semicolons" to remove obsolete semicolons from old theory
wenzelm@60116
  1083

wenzelm@60116

wenzelm@59951
  1085
* Structural composition of proof methods (meth1; meth2) in Isar
wenzelm@59951

corresponds to (tac1 THEN_ALL_NEW tac2) in ML.
haftmann@59105
  1087
wenzelm@60119
  1088
* The Eisbach proof method language allows to define new proof methods
wenzelm@60119
  1089
by combining existing ones with their usual syntax. The "match" proof
wenzelm@60119
  1090
method provides basic fact/term matching in addition to
wenzelm@60119
  1091
premise/conclusion matching through Subgoal.focus, and binds fact names
wenzelm@60288
  1092
from matches as well as term patterns within matches. The Isabelle
wenzelm@60288
  1093
documentation provides an entry "eisbach" for the Eisbach User Manual.

wenzelm@59569
  1100
the "sidekick" mode may be used for document structure.
wenzelm@59569
  1101

  1107
marker, SideKick parser.
wenzelm@58524
  1108
wenzelm@58551
  1109
* Document antiquotation @{cite} provides formal markup, which is
wenzelm@60265
  1110
interpreted semi-formally based on .bib files that happen to be open in
wenzelm@60265
  1111
the editor (hyperlinks, completion etc.).
wenzelm@58551

wenzelm@58785
  1115
wenzelm@60091
  1116
* Improved graphview panel with optional output of PNG or PDF, for
wenzelm@60273
  1117
display of 'thy_deps', 'class_deps' etc.
wenzelm@60010
  1118
wenzelm@60116
  1119
* The commands 'thy_deps' and 'class_deps' allow optional bounds to
wenzelm@60116
  1120
restrict the visualized hierarchy.
wenzelm@60095
  1121
wenzelm@60072
  1122

*** Document preparation ***
wenzelm@59951
  1127
wenzelm@59951
  1128
* Document markup commands 'chapter', 'section', 'subsection',
wenzelm@59951
  1129
'subsubsection', 'text', 'txt', 'text_raw' work uniformly in any
wenzelm@59951
  1130
context, even before the initial 'theory' command. Obsolete proof
wenzelm@59951
  1131
commands 'sect', 'subsect', 'subsubsect', 'txt_raw' have been
wenzelm@59951
  1132
discontinued, use 'section', 'subsection', 'subsubsection', 'text_raw'
wenzelm@59951
  1133
instead. The old 'header' command is still retained for some time, but
wenzelm@59951
  1134
should be replaced by 'chapter', 'section' etc. (using "isabelle
wenzelm@59951
  1135
update_header"). Minor INCOMPATIBILITY.
wenzelm@59951
  1136
wenzelm@60010
  1137
* Official support for "tt" style variants, via \isatt{...} or
wenzelm@60010
  1138
\begin{isabellett}...\end{isabellett}. The somewhat fragile \verb or
wenzelm@60010
  1139
verbatim environment of LaTeX is no longer used. This allows @{ML} etc.
wenzelm@60010
  1140
as argument to other macros (such as footnotes).
wenzelm@60010
  1141
wenzelm@60010
  1142
* Document antiquotation @{verbatim} prints ASCII text literally in "tt"
wenzelm@60010
  1143
style.
wenzelm@60010
  1144
wenzelm@60010
  1145
* Discontinued obsolete option "document_graph": session_graph.pdf is
wenzelm@60010
  1146
produced unconditionally for HTML browser_info and PDF-LaTeX document.
wenzelm@60010
  1147
wenzelm@59951
  1148
* Diagnostic commands and document markup commands within a proof do not
wenzelm@59951
  1149
affect the command tag for output. Thus commands like 'thm' are subject
wenzelm@59951
  1150
to proof document structure, and no longer "stick out" accidentally.
wenzelm@59951
  1151
Commands 'text' and 'txt' merely differ in the LaTeX style, not their
wenzelm@59951
  1152
tags. Potential INCOMPATIBILITY in exotic situations.
wenzelm@59951
  1153
wenzelm@59951
  1154
* System option "pretty_margin" is superseded by "thy_output_margin",
wenzelm@59951
  1155
which is also accessible via document antiquotation option "margin".
wenzelm@59951
  1156
Only the margin for document output may be changed, but not the global
wenzelm@59951
  1157
pretty printing: that is 76 for plain console output, and adapted
wenzelm@59951
  1158
dynamically in GUI front-ends. Implementations of document
wenzelm@59951
  1159
antiquotations need to observe the margin explicitly according to
wenzelm@59951
  1160
Thy_Output.string_of_margin. Minor INCOMPATIBILITY.
wenzelm@59951
  1161
wenzelm@60299
  1162
* Specification of 'document_files' in the session ROOT file is
wenzelm@60299
  1163
mandatory for document preparation. The legacy mode with implicit
wenzelm@60299
  1164
copying of the document/ directory is no longer supported. Minor

wenzelm@59835
  1170
* Proof methods with explicit instantiation ("rule_tac", "subgoal_tac"
wenzelm@59835
  1171
etc.) allow an optional context of local variables ('for' declaration):
wenzelm@59835
  1172
these variables become schematic in the instantiated theorem; this
wenzelm@59835
  1173
behaviour is analogous to 'for' in attributes "where" and "of".
wenzelm@59835
  1174
Configuration option rule_insts_schematic (default false) controls use
wenzelm@59835
  1175
of schematic variables outside the context. Minor INCOMPATIBILITY,
wenzelm@59835
  1176
declare rule_insts_schematic = true temporarily and update to use local
wenzelm@59835
  1177
variable declarations or dummy patterns instead.
wenzelm@59835
  1178
wenzelm@60010
  1179
* Explicit instantiation via attributes "where", "of", and proof methods
wenzelm@60010
  1180
"rule_tac" with derivatives like "subgoal_tac" etc. admit dummy patterns
wenzelm@60010
  1181
("_") that stand for anonymous local variables.
wenzelm@60010
  1182
wenzelm@59951
  1183
* Generated schematic variables in standard format of exported facts are
wenzelm@59951
  1184
incremented to avoid material in the proof context. Rare
wenzelm@59951
  1185
INCOMPATIBILITY, explicit instantiation sometimes needs to refer to
wenzelm@59951
  1186
different index.
wenzelm@59951
  1187
wenzelm@60011
  1188
* Lexical separation of signed and unsigned numerals: categories "num"
wenzelm@60011
  1189
and "float" are unsigned. INCOMPATIBILITY: subtle change in precedence
wenzelm@60011
  1190
of numeral signs, particularly in expressions involving infix syntax
wenzelm@60011
  1191
like "(- 1) ^ n".
haftmann@58410
  1192
wenzelm@58421
  1193
* Old inner token category "xnum" has been discontinued.  Potential
wenzelm@58421
  1194
INCOMPATIBILITY for exotic syntax: may use mixfix grammar with "num"
wenzelm@58421
  1195

* The functions "sin" and "cos" are now defined for any type of sort
wenzelm@60010
  1334
"{real_normed_algebra_1,banach}" type, so in particular on "real" and
wenzelm@60010
  1335
"complex" uniformly. Minor INCOMPATIBILITY: type constraints may be
wenzelm@60010
  1336
needed.
wenzelm@60010
  1337
wenzelm@60010
  1338
* New library of properties of the complex transcendental functions sin,
wenzelm@60010
  1339
cos, tan, exp, Ln, Arctan, Arcsin, Arccos. Ported from HOL Light.
wenzelm@60010
  1340
wenzelm@60010
  1341
* The factorial function, "fact", now has type "nat => 'a" (of a sort
wenzelm@60010
  1342
that admits numeric types including nat, int, real and complex.
wenzelm@60010
  1343
INCOMPATIBILITY: an expression such as "fact 3 = 6" may require a type
wenzelm@60010
  1344
constraint, and the combination "real (fact k)" is likely to be
wenzelm@60010
  1345
unsatisfactory. If a type conversion is still necessary, then use
wenzelm@60010
  1346
"of_nat (fact k)" or "real_of_nat (fact k)".
wenzelm@60010
  1347
wenzelm@60010
  1348
* Removed functions "natfloor" and "natceiling", use "nat o floor" and
wenzelm@60010
  1349
"nat o ceiling" instead. A few of the lemmas have been retained and
wenzelm@60010
  1350
adapted: in their names "natfloor"/"natceiling" has been replaced by
wenzelm@60010
  1351
"nat_floor"/"nat_ceiling".
wenzelm@60010
  1352
wenzelm@60010
  1353
* Qualified some duplicated fact names required for boostrapping the
wenzelm@60010
  1354
type class hierarchy:
wenzelm@60010
  1355
  ab_add_uminus_conv_diff ~> diff_conv_add_uminus
wenzelm@60010
  1356
  field_inverse_zero ~> inverse_zero
wenzelm@60010
  1357
  field_divide_inverse ~> divide_inverse
wenzelm@60010

  field_inverse ~> left_inverse
wenzelm@60010
  1359
Minor INCOMPATIBILITY.
wenzelm@60010
  1360
wenzelm@60010

* Eliminated fact duplicates:
wenzelm@60010
  1362
  mult_less_imp_less_right ~> mult_right_less_imp_less
wenzelm@60010
  1363
  mult_less_imp_less_left ~> mult_left_less_imp_less
wenzelm@60010
  1364
Minor INCOMPATIBILITY.
wenzelm@60010
  1365
wenzelm@60010
  1366
* Fact consolidation: even_less_0_iff is subsumed by
wenzelm@60010
  1367
double_add_less_zero_iff_single_add_less_zero (simp by default anyway).
wenzelm@60010
  1368
wenzelm@60010
  1369
* Generalized and consolidated some theorems concerning divsibility:
wenzelm@60010
  1370
  dvd_reduce ~> dvd_add_triv_right_iff
wenzelm@60010
  1371
  dvd_plus_eq_right ~> dvd_add_right_iff
wenzelm@60010
  1372
  dvd_plus_eq_left ~> dvd_add_left_iff
wenzelm@60010
  1373
Minor INCOMPATIBILITY.
wenzelm@60010
  1374
wenzelm@60010
  1375
* "even" and "odd" are mere abbreviations for "2 dvd _" and "~ 2 dvd _"
wenzelm@60010
  1376
and part of theory Main.
wenzelm@60010
  1377
  even_def ~> even_iff_mod_2_eq_zero
wenzelm@60010
  1378
INCOMPATIBILITY.
wenzelm@60010
  1379
wenzelm@60010
  1380
* Lemma name consolidation: divide_Numeral1 ~> divide_numeral_1. Minor
wenzelm@60010
  1381
INCOMPATIBILITY.
wenzelm@60010
  1382
wenzelm@60010
  1383
* Bootstrap of listsum as special case of abstract product over lists.
wenzelm@60010
  1384
Fact rename:
wenzelm@60010
  1385
    listsum_def ~> listsum.eq_foldr

  1386
INCOMPATIBILITY.
wenzelm@60010

  1388
* Product over lists via constant "listprod".
wenzelm@60010
  1389
wenzelm@60010
  1390
* Theory List: renamed drop_Suc_conv_tl and nth_drop' to
wenzelm@60010
  1391
Cons_nth_drop_Suc.
nipkow@58247

Andreas@58626
  1393
* New infrastructure for compiling, running, evaluating and testing
wenzelm@59569
  1394
generated code in target languages in HOL/Library/Code_Test. See
wenzelm@59569
  1395

  1396
wenzelm@60010
  1397
* Library/Multiset:
blanchet@59813
  1398
  - Introduced "replicate_mset" operation.
blanchet@59813
  1399
  - Introduced alternative characterizations of the multiset ordering in
blanchet@59813
  1400
    "Library/Multiset_Order".
blanchet@59958
  1401
  - Renamed multiset ordering:

      \<subseteq># ~> #\<subseteq>#
blanchet@59958
  1406
    INCOMPATIBILITY.
blanchet@59986
  1407
  - Introduced abbreviations for ill-named multiset operations:
blanchet@59986
  1408
      <#, \<subset># abbreviate < (strict subset)
blanchet@59986
  1409
      <=#, \<le>#, \<subseteq># abbreviate <= (subset or equal)
blanchet@59986
  1410
    INCOMPATIBILITY.
blanchet@59813
  1411
  - Renamed
blanchet@59813
  1412
      in_multiset_of ~> in_multiset_in_set
nipkow@59998
  1413
      Multiset.fold ~> fold_mset

  1414
      Multiset.filter ~> filter_mset
blanchet@59813
  1415
    INCOMPATIBILITY.
nipkow@59949
  1416
  - Removed mcard, is equal to size.
blanchet@59813
  1417
  - Added attributes:

  1426
    INCOMPATIBILITY.
blanchet@59813
  1427
wenzelm@60010
  1428
* Library/Sum_of_Squares: simplified and improved "sos" method. Always
wenzelm@60010
  1429
use local CSDP executable, which is much faster than the NEOS server.
wenzelm@60010
  1430
The "sos_cert" functionality is invoked as "sos" with additional
wenzelm@60010
  1431
argument. Minor INCOMPATIBILITY.
wenzelm@60010
  1432
wenzelm@60010
  1433
* HOL-Decision_Procs: New counterexample generator quickcheck
wenzelm@60010
  1434
[approximation] for inequalities of transcendental functions. Uses
wenzelm@60010
  1435
hardware floating point arithmetic to randomly discover potential
wenzelm@60011
  1436
counterexamples. Counterexamples are certified with the "approximation"
wenzelm@60010
  1437
method. See HOL/Decision_Procs/ex/Approximation_Quickcheck_Ex.thy for
wenzelm@60010
  1438
examples.

hoelzl@59354
  1440
* HOL-Probability: Reworked measurability prover
wenzelm@60011
  1441
  - applies destructor rules repeatedly
hoelzl@59354
  1442
  - removed application splitting (replaced by destructor rule)
wenzelm@59569
  1443
  - added congruence rules to rewrite measure spaces under the sets
wenzelm@59569
  1444
    projection
wenzelm@59569
  1445
wenzelm@60010

wenzelm@60010
  1447
single-step rewriting with subterm selection based on patterns.

  1450
*** ML ***
blanchet@58066
  1451
wenzelm@60010
  1452
* Subtle change of name space policy: undeclared entries are now
wenzelm@60010
  1453
considered inaccessible, instead of accessible via the fully-qualified
wenzelm@60010
  1454
internal name. This mainly affects Name_Space.intern (and derivatives),
wenzelm@60010
  1455
which may produce an unexpected Long_Name.hidden prefix. Note that
wenzelm@60011
  1456
contemporary applications use the strict Name_Space.check (and
wenzelm@60010
  1457
derivatives) instead, which is not affected by the change. Potential
wenzelm@60010
  1458
INCOMPATIBILITY in rare applications of Name_Space.intern.
wenzelm@59951
  1459
wenzelm@60096
  1460
* Subtle change of error semantics of Toplevel.proof_of: regular user
wenzelm@60096
  1461
ERROR instead of internal Toplevel.UNDEF.
wenzelm@60096
  1462
wenzelm@59951
  1463
* Basic combinators map, fold, fold_map, split_list, apply are available
wenzelm@59951
  1464
as parameterized antiquotations, e.g. @{map 4} for lists of quadruples.
wenzelm@59951
  1465
wenzelm@59951
  1466
* Renamed "pairself" to "apply2", in accordance to @{apply 2}.
wenzelm@59951
  1467
INCOMPATIBILITY.
wenzelm@59951
  1468
wenzelm@59951
  1469
* Former combinators NAMED_CRITICAL and CRITICAL for central critical
wenzelm@59951
  1470
sections have been discontinued, in favour of the more elementary
wenzelm@59951
  1471
Multithreading.synchronized and its high-level derivative
wenzelm@59951
  1472
Synchronized.var (which is usually sufficient in applications). Subtle
wenzelm@59951
  1473
INCOMPATIBILITY: synchronized access needs to be atomic and cannot be
wenzelm@59951
  1474
nested.
wenzelm@59951
  1475
wenzelm@60010
  1476
* Synchronized.value (ML) is actually synchronized (as in Scala): subtle
wenzelm@60010
  1477
change of semantics with minimal potential for INCOMPATIBILITY.
wenzelm@59899
  1478
wenzelm@59621
  1479
* The main operations to certify logical entities are Thm.ctyp_of and
wenzelm@59621
  1480
Thm.cterm_of with a local context; old-style global theory variants are
wenzelm@59621
  1481
available as Thm.global_ctyp_of and Thm.global_cterm_of.
wenzelm@59621
  1482
INCOMPATIBILITY.
wenzelm@59621
  1483
wenzelm@59582
  1484
* Elementary operations in module Thm are no longer pervasive.
wenzelm@59582
  1485
INCOMPATIBILITY, need to use qualified Thm.prop_of, Thm.cterm_of,
wenzelm@59582
  1486
Thm.term_of etc.
wenzelm@59582
  1487
wenzelm@58963
  1488
* Proper context for various elementary tactics: assume_tac,
wenzelm@59498
  1489
resolve_tac, eresolve_tac, dresolve_tac, forward_tac, match_tac,
wenzelm@59498
  1490
compose_tac, Splitter.split_tac etc. INCOMPATIBILITY.
wenzelm@58956
  1491
blanchet@58066
  1492
* Tactical PARALLEL_ALLGOALS is the most common way to refer to
blanchet@58066
  1493
PARALLEL_GOALS.
blanchet@58066
  1494
wenzelm@59564
  1495
* Goal.prove_multi is superseded by the fully general Goal.prove_common,
wenzelm@59564
  1496
which also allows to specify a fork priority.
wenzelm@59564
  1497
wenzelm@59936
  1498
* Antiquotation @{command_spec "COMMAND"} is superseded by
wenzelm@59936
  1499
@{command_keyword COMMAND} (usually without quotes and with PIDE
wenzelm@59936
  1500
markup). Minor INCOMPATIBILITY.
wenzelm@59936
  1501
wenzelm@60010
  1502
* Cartouches within ML sources are turned into values of type
wenzelm@60010

  1509
cartouches instead of old-style {* verbatim *} or `alt_string` tokens.
wenzelm@59951
  1510
wenzelm@60108

* The Isabelle tool "build" provides new options -X, -k, -x.
wenzelm@59951
  1512
wenzelm@59951
  1513
* Discontinued old-fashioned "codegen" tool. Code generation can always
wenzelm@59951
  1514
be externally triggered using an appropriate ROOT file plus a
wenzelm@59951
  1515
corresponding theory. Parametrization is possible using environment

  1534
*** General ***
wenzelm@54702
  1535
wenzelm@57452
  1536
* Support for official Standard ML within the Isabelle context.
wenzelm@57452
  1537
Command 'SML_file' reads and evaluates the given Standard ML file.
wenzelm@57452
  1538
Toplevel bindings are stored within the theory context; the initial
wenzelm@57452
  1539
environment is restricted to the Standard ML implementation of
wenzelm@57452
  1540
Poly/ML, without the add-ons of Isabelle/ML.  Commands 'SML_import'
wenzelm@57452
  1541
and 'SML_export' allow to exchange toplevel bindings between the two
wenzelm@57452
  1542
separate environments.  See also ~~/src/Tools/SML/Examples.thy for
wenzelm@57452
  1543
some examples.
wenzelm@56499
  1544
wenzelm@57504
  1545
* Standard tactics and proof methods such as "clarsimp", "auto" and
wenzelm@57504
  1546
"safe" now preserve equality hypotheses "x = expr" where x is a free
wenzelm@57504
  1547
variable.  Locale assumptions and chained facts containing "x"
wenzelm@57504
  1548
continue to be useful.  The new method "hypsubst_thin" and the
wenzelm@57504
  1549
configuration option "hypsubst_thin" (within the attribute name space)
wenzelm@57504
  1550
restore the previous behavior.  INCOMPATIBILITY, especially where
wenzelm@57504
  1551
induction is done after these methods or when the names of free and
wenzelm@57504
  1552
bound variables clash.  As first approximation, old proofs may be
wenzelm@57504
  1553
repaired by "using [[hypsubst_thin = true]]" in the critical spot.
wenzelm@57504
  1554
wenzelm@56232
  1555
* More static checking of proof methods, which allows the system to
wenzelm@56232
  1556
form a closure over the concrete syntax.  Method arguments should be
wenzelm@56232
  1557
processed in the original proof context as far as possible, before
wenzelm@56232
  1558
operating on the goal state.  In any case, the standard discipline for
wenzelm@56232
  1559
subgoal-addressing needs to be observed: no subgoals or a subgoal
wenzelm@56232
  1560
number that is out of range produces an empty result sequence, not an
wenzelm@56232
  1561
exception.  Potential INCOMPATIBILITY for non-conformant tactical
wenzelm@56232
  1562
proof tools.
wenzelm@56232
  1563
wenzelm@57452
  1564
* Lexical syntax (inner and outer) supports text cartouches with
wenzelm@57452
  1565
arbitrary nesting, and without escapes of quotes etc.  The Prover IDE
wenzelm@57452
  1566
supports input via ` (backquote).
wenzelm@57452
  1567
wenzelm@57452
  1568
* The outer syntax categories "text" (for formal comments and document
wenzelm@57452
  1569
markup commands) and "altstring" (for literal fact references) allow
wenzelm@57452
  1570
cartouches as well, in addition to the traditional mix of quotations.
wenzelm@57452
  1571
wenzelm@57452
  1572
* Syntax of document antiquotation @{rail} now uses \<newline> instead
wenzelm@57452
  1573
of "\\", to avoid the optical illusion of escaped backslash within
wenzelm@57491
  1574
string token.  General renovation of its syntax using text cartouches.
wenzelm@57452
  1575
Minor INCOMPATIBILITY.
wenzelm@57452
  1576
wenzelm@57452
  1577
* Discontinued legacy_isub_isup, which was a temporary workaround for
wenzelm@57452
  1578
Isabelle/ML in Isabelle2013-1.  The prover process no longer accepts
wenzelm@57452
  1579
old identifier syntax with \<^isub> or \<^isup>.  Potential
wenzelm@57452
  1580
INCOMPATIBILITY.
wenzelm@57452
  1581
wenzelm@57452
  1582
* Document antiquotation @{url} produces markup for the given URL,
wenzelm@57452
  1583
which results in an active hyperlink within the text.
wenzelm@57452
  1584
wenzelm@57452
  1585
* Document antiquotation @{file_unchecked} is like @{file}, but does
wenzelm@57452
  1586
not check existence within the file-system.
wenzelm@57452

* Auxiliary files ('ML_file' etc.) are managed by the Prover IDE.
wenzelm@57452
  1602
Open text buffers take precedence over copies within the file-system.
wenzelm@57452
  1603
wenzelm@57452
  1604
* Improved support for Isabelle/ML, with jEdit mode "isabelle-ml" for
wenzelm@57452
  1605
auxiliary ML files.
wenzelm@57423
  1606
wenzelm@57423
  1607
* Improved syntactic and semantic completion mechanism, with simple
wenzelm@57423
  1608
templates, completion language context, name-space completion,
wenzelm@57423
  1609
file-name completion, spell-checker completion.
wenzelm@57423
  1610
wenzelm@57423
  1611
* Refined GUI popup for completion: more robust key/mouse event
wenzelm@57423
  1612
handling and propagation to enclosing text area -- avoid loosing
wenzelm@57423
  1613
keystrokes with slow / remote graphics displays.
wenzelm@57423
  1614
wenzelm@57833
  1615
* Completion popup supports both ENTER and TAB (default) to select an
wenzelm@57833
  1616
item, depending on Isabelle options.
wenzelm@57833
  1617
wenzelm@57423
  1618
* Refined insertion of completion items wrt. jEdit text: multiple
wenzelm@57423
  1619
selections, rectangular selections, rectangular selection as "tall
wenzelm@57423
  1620
caret".
wenzelm@56342
  1621
wenzelm@56580
  1622
* Integrated spell-checker for document text, comments etc. with
wenzelm@57423
  1623
completion popup and context-menu.
wenzelm@56554
  1624
wenzelm@56879
  1625
* More general "Query" panel supersedes "Find" panel, with GUI access
wenzelm@56879
  1626
to commands 'find_theorems' and 'find_consts', as well as print
wenzelm@56879
  1627
operations for the context.  Minor incompatibility in keyboard
wenzelm@56879
  1628
shortcuts etc.: replace action isabelle-find by isabelle-query.
wenzelm@56761
  1629
wenzelm@56901
  1630
* Search field for all output panels ("Output", "Query", "Info" etc.)
wenzelm@56901
  1631
to highlight text via regular expression.
wenzelm@56901
  1632
wenzelm@54881
  1633
* Option "jedit_print_mode" (see also "Plugin Options / Isabelle /
wenzelm@54881
  1634
General") allows to specify additional print modes for the prover
wenzelm@54881
  1635
process, without requiring old-fashioned command-line invocation of
wenzelm@54881
  1636
"isabelle jedit -m MODE".
wenzelm@54881
  1637
wenzelm@56505
  1638
* More support for remote files (e.g. http) using standard Java
wenzelm@56505
  1639
networking operations instead of jEdit virtual file-systems.
wenzelm@56505
  1640
wenzelm@57822
  1641
* Empty editors buffers that are no longer required (e.g.\ via theory
wenzelm@57822
  1642
imports) are automatically removed from the document model.
wenzelm@57822
  1643
wenzelm@57869
  1644
* Improved monitor panel.
wenzelm@57869
  1645
wenzelm@56838
  1646
* Improved Console/Scala plugin: more uniform scala.Console output,
wenzelm@56838
  1647
more robust treatment of threads and interrupts.
wenzelm@56838
  1648
wenzelm@56939
  1649
* Improved management of dockable windows: clarified keyboard focus
wenzelm@56939
  1650
and window placement wrt. main editor view; optional menu item to
wenzelm@56939
  1651
"Detach" a copy where this makes sense.
wenzelm@56939
  1652
wenzelm@57452
  1653
* New Simplifier Trace panel provides an interactive view of the
wenzelm@57594
  1654
simplification process, enabled by the "simp_trace_new" attribute
wenzelm@57452
  1655
within the context.

*** Pure ***
wenzelm@55001
  1659
wenzelm@57504
  1660
* Low-level type-class commands 'classes', 'classrel', 'arities' have
wenzelm@57504
  1661
been discontinued to avoid the danger of non-trivial axiomatization
wenzelm@57504
  1662
that is not immediately visible.  INCOMPATIBILITY, use regular
wenzelm@57504
  1663
'instance' command with proof.  The required OFCLASS(...) theorem
wenzelm@57504
  1664
might be postulated via 'axiomatization' beforehand, or the proof
wenzelm@57504
  1665
finished trivially if the underlying class definition is made vacuous
wenzelm@57504
  1666
(without any assumptions).  See also Isabelle/ML operations
wenzelm@57504
  1667
Axclass.class_axiomatization, Axclass.classrel_axiomatization,

Axclass.arity_axiomatization.
wenzelm@57504
  1669
wenzelm@56245
  1670
* Basic constants of Pure use more conventional names and are always
wenzelm@56245
  1671
qualified.  Rare INCOMPATIBILITY, but with potentially serious
wenzelm@56245
  1672
consequences, notably for tools in Isabelle/ML.  The following
wenzelm@56245
  1673
renaming needs to be applied:
wenzelm@56245
  1674
wenzelm@56245
  1675
  ==             ~>  Pure.eq
wenzelm@56245
  1676
  ==>            ~>  Pure.imp
wenzelm@56245
  1677
  all            ~>  Pure.all
wenzelm@56245
  1678
  TYPE           ~>  Pure.type
wenzelm@56245
  1679
  dummy_pattern  ~>  Pure.dummy_pattern
wenzelm@56245
  1680
wenzelm@56245
  1681
Systematic porting works by using the following theory setup on a
wenzelm@56245
  1682
*previous* Isabelle version to introduce the new name accesses for the
wenzelm@56245
  1683
old constants:
wenzelm@56245
  1684
wenzelm@56245
  1685
setup {*
wenzelm@56245
  1686
  fn thy => thy
wenzelm@56245
  1687
    |> Sign.root_path
wenzelm@56245
  1688
    |> Sign.const_alias (Binding.qualify true "Pure" @{binding eq}) "=="
wenzelm@56245
  1689
    |> Sign.const_alias (Binding.qualify true "Pure" @{binding imp}) "==>"
wenzelm@56245
  1690
    |> Sign.const_alias (Binding.qualify true "Pure" @{binding all}) "all"
wenzelm@56245
  1691
    |> Sign.restore_naming thy
wenzelm@56245
  1692
*}
wenzelm@56245
  1693
wenzelm@56245
  1694
Thus ML antiquotations like @{const_name Pure.eq} may be used already.
wenzelm@56245
  1695
Later the application is moved to the current Isabelle version, and
wenzelm@56245
  1696
the auxiliary aliases are deleted.
wenzelm@56245
  1697
wenzelm@55143
  1698
* Attributes "where" and "of" allow an optional context of local
wenzelm@55143
  1699
variables ('for' declaration): these variables become schematic in the
wenzelm@55143
  1700
instantiated theorem.
wenzelm@55143
  1701
wenzelm@55152
  1702
* Obsolete attribute "standard" has been discontinued (legacy since
wenzelm@55152
  1703
Isabelle2012).  Potential INCOMPATIBILITY, use explicit 'for' context
wenzelm@55152
  1704
where instantiations with schematic variables are intended (for
wenzelm@55152
  1705
declaration commands like 'lemmas' or attributes like "of").  The
wenzelm@55152
  1706
following temporary definition may help to port old applications:
wenzelm@55152
  1707
wenzelm@55152
  1708
  attribute_setup standard =
wenzelm@55152
  1709
    "Scan.succeed (Thm.rule_attribute (K Drule.export_without_context))"
wenzelm@55152
  1710
wenzelm@55001
  1711
* More thorough check of proof context for goal statements and
wenzelm@55006
  1712
attributed fact expressions (concerning background theory, declared
wenzelm@55006
  1713
hyps).  Potential INCOMPATIBILITY, tools need to observe standard
wenzelm@55006
  1714
context discipline.  See also Assumption.add_assumes and the more
wenzelm@55006
  1715
primitive Thm.assume_hyps.
wenzelm@55001
  1716
wenzelm@55108
  1717
* Inner syntax token language allows regular quoted strings "..."
wenzelm@55108
  1718
(only makes sense in practice, if outer syntax is delimited
wenzelm@57452
  1719
differently, e.g. via cartouches).
wenzelm@57452
  1720
wenzelm@57504
  1721
* Command 'print_term_bindings' supersedes 'print_binds' for clarity,
wenzelm@57504
  1722
but the latter is retained some time as Proof General legacy.
wenzelm@57504
  1723
wenzelm@57452
  1724
* Code generator preprocessor: explicit control of simp tracing on a
wenzelm@57452
  1725
per-constant basis.  See attribute "code_preproc".

  1731
language requirements.  INCOMPATIBILITY.
wenzelm@57504
  1732
wenzelm@57504
  1733
* Code generator: explicit proof contexts in many ML interfaces.
wenzelm@57504
  1734
INCOMPATIBILITY.
wenzelm@57504
  1735
wenzelm@57504
  1736
* Code generator: minimize exported identifiers by default.  Minor

  1737
INCOMPATIBILITY.
wenzelm@57504
  1738
wenzelm@57504
  1739
* Code generation for SML and OCaml: dropped arcane "no_signatures"
wenzelm@57504
  1740
option.  Minor INCOMPATIBILITY.
wenzelm@57504
  1741
wenzelm@57504
  1742
* "declare [[code abort: ...]]" replaces "code_abort ...".

INCOMPATIBILITY.
wenzelm@57504
  1744
wenzelm@57504
  1745
* "declare [[code drop: ...]]" drops all code equations associated
wenzelm@57504
  1746
with the given constants.
wenzelm@57504
  1747
wenzelm@57504
  1748
* Code generations are provided for make, fields, extend and truncate
wenzelm@57504
  1749
operations on records.
haftmann@57437
  1750
wenzelm@57452
  1751
* Command and antiquotation "value" are now hardcoded against nbe and
wenzelm@57452
  1752
ML.  Minor INCOMPATIBILITY.
wenzelm@57452
  1753
wenzelm@57504
  1754
* Renamed command 'enriched_type' to 'functor'. INCOMPATIBILITY.
wenzelm@57504
  1755
wenzelm@57504
  1756
* The symbol "\<newline>" may be used within char or string literals
wenzelm@57504
  1757
to represent (Char Nibble0 NibbleA), i.e. ASCII newline.
wenzelm@57504
  1758
wenzelm@57504
  1759
* Qualified String.implode and String.explode.  INCOMPATIBILITY.
haftmann@56923
  1760
wenzelm@57452
  1761
* Simplifier: Enhanced solver of preconditions of rewrite rules can
wenzelm@57452
  1762
now deal with conjunctions.  For help with converting proofs, the old
wenzelm@57452
  1763
behaviour of the simplifier can be restored like this: declare/using
wenzelm@57452
  1764
[[simp_legacy_precond]].  This configuration option will disappear
wenzelm@57452
  1765
again in the future.  INCOMPATIBILITY.
nipkow@56073
  1766
wenzelm@55139
  1767
* Simproc "finite_Collect" is no longer enabled by default, due to
wenzelm@55139
  1768
spurious crashes and other surprises.  Potential INCOMPATIBILITY.
wenzelm@55139
  1769
wenzelm@57452
  1770
* Moved new (co)datatype package and its dependencies from session
wenzelm@57452
  1771
  "HOL-BNF" to "HOL".  The commands 'bnf', 'wrap_free_constructors',
wenzelm@57452
  1772
  'datatype_new', 'codatatype', 'primcorec', 'primcorecursive' are now
wenzelm@57452

* New (co)datatype package:
wenzelm@57452
  1813
  - Command 'primcorec' is fully implemented.
wenzelm@57452
  1814
  - Command 'datatype_new' generates size functions ("size_xxx" and
wenzelm@57452
  1815
    "size") as required by 'fun'.
wenzelm@57452
  1816
  - BNFs are integrated with the Lifting tool and new-style
wenzelm@57452
  1817
    (co)datatypes with Transfer.
wenzelm@57452
  1818
  - Renamed commands:

    INCOMPATIBILITY.
blanchet@55875
  1837
blanchet@55643
  1838
* Old datatype package:
wenzelm@57452
  1839
  - The generated theorems "xxx.cases" and "xxx.recs" have been
wenzelm@57452
  1840
    renamed "xxx.case" and "xxx.rec" (e.g., "sum.cases" ->
wenzelm@57452
  1841
    "sum.case").  INCOMPATIBILITY.
wenzelm@57452
  1842
  - The generated constants "xxx_case", "xxx_rec", and "xxx_size" have
wenzelm@57452
  1843
    been renamed "case_xxx", "rec_xxx", and "size_xxx" (e.g.,

* New internal SAT solver "cdclite" that produces models and proof
wenzelm@57508
  1920
traces.  This solver replaces the internal SAT solvers "enumerate" and
wenzelm@57508
  1921
"dpll".  Applications that explicitly used one of these two SAT
wenzelm@57508
  1922
solvers should use "cdclite" instead. In addition, "cdclite" is now
wenzelm@57508
  1923
the default SAT solver for the "sat" and "satx" proof methods and
wenzelm@57508
  1924
corresponding tactics; the old default can be restored using "declare
wenzelm@57508

[[sat_solver = zchaff_with_proofs]]".  Minor INCOMPATIBILITY.
wenzelm@57508

wenzelm@57508
  1927
* SMT module: A new version of the SMT module, temporarily called
wenzelm@57508
  1928
"SMT2", uses SMT-LIB 2 and supports recent versions of Z3 (e.g.,
wenzelm@57508
  1929
4.3). The new proof method is called "smt2". CVC3 and CVC4 are also
wenzelm@57508
  1930
supported as oracles. Yices is no longer supported, because no version
wenzelm@57508
  1931
of the solver can handle both SMT-LIB 2 and quantifiers.
wenzelm@57508
  1932
wenzelm@57508
  1933
* Activation of Z3 now works via "z3_non_commercial" system option
wenzelm@57508

  - Z3 can now produce Isar proofs.
wenzelm@57508
  1940
  - MaSh overhaul:
blanchet@57532
  1941
    . New SML-based learning algorithms eliminate the dependency on
wenzelm@57508
  1942
      Python and increase performance and reliability.
wenzelm@57508
  1943
    . MaSh and MeSh are now used by default together with the
wenzelm@57508
  1944
      traditional MePo (Meng-Paulson) relevance filter. To disable
wenzelm@57508
  1945
      MaSh, set the "MaSh" system option in Isabelle/jEdit Plugin
wenzelm@57508
  1946
      Options / Isabelle / General to "none".

wenzelm@57508
  1956
wenzelm@57508
  1957
* Nitpick:
wenzelm@57508
  1958
  - Fixed soundness bug whereby mutually recursive datatypes could
wenzelm@57508
  1959
    take infinite values.
wenzelm@57508
  1960
  - Fixed soundness bug with low-level number functions such as
wenzelm@57508
  1961
    "Abs_Integ" and "Rep_Integ".
wenzelm@57508
  1962
  - Removed "std" option.
wenzelm@57508
  1963
  - Renamed "show_datatypes" to "show_types" and "hide_datatypes" to
wenzelm@57508
  1964
    "hide_types".
wenzelm@57508
  1965
wenzelm@57508
  1966

(full_types)' instead. INCOMPATIBILITY.
wenzelm@57508
  1968
wenzelm@57508

wenzelm@57508
  1970
wenzelm@57508
  1971
* Adjustion of INF and SUP operations:
wenzelm@57508
  1972
  - Elongated constants INFI and SUPR to INFIMUM and SUPREMUM.
wenzelm@57508
  1973
  - Consolidated theorem names containing INFI and SUPR: have INF and
wenzelm@57508
  1974
    SUP instead uniformly.
wenzelm@57508
  1975
  - More aggressive normalization of expressions involving INF and Inf
wenzelm@57508
  1976
    or SUP and Sup.
wenzelm@57508
  1977
  - INF_image and SUP_image do not unfold composition.
wenzelm@57508
  1978
  - Dropped facts INF_comp, SUP_comp.
wenzelm@57508
  1979
  - Default congruence rules strong_INF_cong and strong_SUP_cong, with
wenzelm@57508
  1980
    simplifier implication in premises.  Generalize and replace former

  - Changed order of ordered_euclidean_space to be compatible with

select_markup have been clarified.  Markup is now traversed in the

* Subtle change of semantics of Thm.eq_thm: theory stamps are not
wenzelm@57504
  2525
compared (according to Thm.thm_ord), but assumed to be covered by the
wenzelm@57504
  2526
current background theory.  Thus equivalent data produced in different
wenzelm@57504
  2527
branches of the theory graph usually coincides (e.g. relevant for
wenzelm@57504
  2528
theory merge).  Note that the softer Thm.eq_thm_prop is often more
wenzelm@57504
  2529
appropriate than Thm.eq_thm.

actually belongs to it).
wenzelm@57504

wenzelm@57504
  2536
* Proper context discipline for read_instantiate and instantiate_tac:
wenzelm@57504
  2537
variables that are meant to become schematic need to be given as
wenzelm@57504
  2538
fixed, and are generalized by the explicit context of local variables.
wenzelm@57504
  2539
This corresponds to Isar attributes "where" and "of" with 'for'
wenzelm@57504
  2540
declaration.  INCOMPATIBILITY, also due to potential change of indices
wenzelm@57504
  2541
of schematic variables.

depth of the ML compiler within the context.  The old print_depth in

  2556
INCOMPATIBILITY.

occasionally useful for experimentation and diagnostic purposes.
wenzelm@56071
  2568
wenzelm@56135
  2569
* ML antiquotation @{path} produces a Path.T value, similarly to
wenzelm@56135
  2570
Path.explode, but with compile-time check against the file-system and
wenzelm@56135
  2571
some PIDE markup.  Note that unlike theory source, ML does not have a
wenzelm@56135
  2572
well-defined master directory, so an absolute symbolic path
wenzelm@56135
  2573
specification is usually required, e.g. "~~/src/HOL".
wenzelm@56135

wenzelm@56399
  2575
* ML antiquotation @{print} inlines a function to print an arbitrary

* The raw Isabelle process executable has been renamed from
wenzelm@56439
  2589
"isabelle-process" to "isabelle_process", which conforms to common
wenzelm@56439
  2590
shell naming conventions, and allows to define a shell function within
wenzelm@56439
  2591
the Isabelle environment to avoid dynamic path lookup.  Rare

wenzelm@57413
  2606
for email communication is the Unicode rendering of Isabelle symbols,
wenzelm@57413
  2607
as produced by Isabelle/jEdit, for example.
wenzelm@57413
  2608
wenzelm@57452
  2609
* Removed obsolete tool "wwwfind". Similar functionality may be
wenzelm@57452
  2610
integrated into Isabelle/jEdit eventually.
wenzelm@57452
  2611
wenzelm@57452
  2612
* Improved 'display_drafts' concerning desktop integration and
wenzelm@57452
  2613
repeated invocation in PIDE front-end: re-use single file
wenzelm@57452
  2614
$ISABELLE_HOME_USER/tmp/drafts.pdf and corresponding views.
wenzelm@57084
  2615
wenzelm@57452
  2616
* Session ROOT specifications require explicit 'document_files' for
wenzelm@57452
  2617
robust dependencies on LaTeX sources.  Only these explicitly given
wenzelm@57452
  2618
files are copied to the document output directory, before document
wenzelm@57452
  2619
processing is started.
wenzelm@57452
  2620
wenzelm@57504
  2621
* Windows: support for regular TeX installation (e.g. MiKTeX) instead
wenzelm@57504
  2622
of TeX Live from Cygwin.

*** Prover IDE -- Isabelle/Scala/jEdit ***
wenzelm@54639
  2630
wenzelm@54639
  2631
* More robust editing of running commands with internal forks,
wenzelm@54639
  2632
e.g. non-terminating 'by' steps.
wenzelm@54639
  2633
wenzelm@54641
  2634
* More relaxed Sledgehammer panel: avoid repeated application of query
wenzelm@54641
  2635
after edits surrounding the command location.
wenzelm@54641
  2636
wenzelm@54648
  2637
* More status information about commands that are interrupted
wenzelm@54648
  2638
accidentally (via physical event or Poly/ML runtime system signal,
wenzelm@54648
  2639
e.g. out-of-memory).

*** System ***
wenzelm@54653
  2643
wenzelm@54653
  2644
* More robust termination of external processes managed by
wenzelm@54664
  2645
Isabelle/ML: support cancellation of tasks within the range of
wenzelm@54664
  2646
milliseconds, as required for PIDE document editing with automatically
wenzelm@54664
  2647
tried tools (e.g. Sledgehammer).
wenzelm@54653
  2648
wenzelm@54648
  2649
* Reactivated Isabelle/Scala kill command for external processes on
wenzelm@54648
  2650
Mac OS X, which was accidentally broken in Isabelle2013-1 due to a
wenzelm@54648
  2651
workaround for some Debian/Ubuntu Linux versions from 2013.

*** General ***
wenzelm@51293
  2659
wenzelm@53971
  2660
* Discontinued obsolete 'uses' within theory header.  Note that
wenzelm@53971
  2661
commands like 'ML_file' work without separate declaration of file
wenzelm@53971
  2662
dependencies.  Minor INCOMPATIBILITY.
wenzelm@53971
  2663
wenzelm@53971
  2664
* Discontinued redundant 'use' command, which was superseded by
wenzelm@53971
  2665
'ML_file' in Isabelle2013.  Minor INCOMPATIBILITY.
wenzelm@53971
  2666
wenzelm@53016
  2667
* Simplified subscripts within identifiers, using plain \<^sub>
wenzelm@53016
  2668
instead of the second copy \<^isub> and \<^isup>.  Superscripts are
wenzelm@53016
  2669
only for literal tokens within notation; explicit mixfix annotations
wenzelm@53016
  2670
for consts or fixed variables may be used as fall-back for unusual
wenzelm@53016
  2671
names.  Obsolete \<twosuperior> has been expanded to \<^sup>2 in
wenzelm@53016
  2672
Isabelle/HOL.  INCOMPATIBILITY, use "isabelle update_sub_sup" to
wenzelm@53016
  2673
standardize symbols as a starting point for further manual cleanup.
wenzelm@53016
  2674
The ML reference variable "legacy_isub_isup" may be set as temporary
wenzelm@53016
  2675
workaround, to make the prover accept a subset of the old identifier
wenzelm@53016
  2676
syntax.
wenzelm@53016
  2677
wenzelm@53021
  2678
* Document antiquotations: term style "isub" has been renamed to
wenzelm@53021
  2679
"sub".  Minor INCOMPATIBILITY.
wenzelm@53021
  2680
wenzelm@52487
  2681
* Uniform management of "quick_and_dirty" as system option (see also
wenzelm@52487
  2682
"isabelle options"), configuration option within the context (see also
wenzelm@52487
  2683
Config.get in Isabelle/ML), and attribute in Isabelle/Isar.  Minor
wenzelm@52487
  2684
INCOMPATIBILITY, need to use more official Isabelle means to access
wenzelm@52487
  2685
quick_and_dirty, instead of historical poking into mutable reference.
wenzelm@52059
  2686
wenzelm@52060
  2687
* Renamed command 'print_configs' to 'print_options'.  Minor
wenzelm@52060
  2688
INCOMPATIBILITY.
wenzelm@52060
  2689
wenzelm@52430
  2690
* Proper diagnostic command 'print_state'.  Old 'pr' (with its
wenzelm@52430
  2691
implicit change of some global references) is retained for now as
wenzelm@52430
  2692
control command, e.g. for ProofGeneral 3.7.x.
wenzelm@52430
  2693
wenzelm@52549
  2694
* Discontinued 'print_drafts' command with its old-fashioned PS output
wenzelm@52549
  2695
and Unix command-line print spooling.  Minor INCOMPATIBILITY: use
wenzelm@52549
  2696
'display_drafts' instead and print via the regular document viewer.
wenzelm@52549
  2697
wenzelm@53971
  2698
* Updated and extended "isar-ref" and "implementation" manual,
wenzelm@53971
  2699
eliminated old "ref" manual.

*** Prover IDE -- Isabelle/Scala/jEdit ***
wenzelm@51533
  2703
wenzelm@53971
  2704
* New manual "jedit" for Isabelle/jEdit, see isabelle doc or
wenzelm@53852
  2705
Documentation panel.
wenzelm@53852
  2706
wenzelm@53971
  2707
* Dockable window "Documentation" provides access to Isabelle
wenzelm@53971
  2708
documentation.
wenzelm@52646
  2709
wenzelm@52949
  2710
* Dockable window "Find" provides query operations for formal entities
wenzelm@52949
  2711
(GUI front-end to 'find_theorems' command).
wenzelm@52949
  2712
wenzelm@53050
  2713
* Dockable window "Sledgehammer" manages asynchronous / parallel
wenzelm@53050
  2714
sledgehammer runs over existing document sources, independently of
wenzelm@53050
  2715
normal editing and checking process.
wenzelm@53050
  2716
wenzelm@51533
  2717
* Dockable window "Timing" provides an overview of relevant command
wenzelm@54332
  2718
timing information, depending on option jedit_timing_threshold.  The
wenzelm@54332
  2719
same timing information is shown in the extended tooltip of the
wenzelm@54332
  2720
command keyword, when hovering the mouse over it while the CONTROL or
wenzelm@54332
  2721
COMMAND modifier is pressed.
