*** General ***
wenzelm@61337
    11
wenzelm@61337
    12
* Toplevel theorem statements have been simplified as follows:
wenzelm@61337
    13
wenzelm@61337
    14
  theorems             ~>  lemmas
wenzelm@61337
    15
  schematic_lemma      ~>  schematic_goal
wenzelm@61337
    16
  schematic_theorem    ~>  schematic_goal
wenzelm@61337
    17
  schematic_corollary  ~>  schematic_goal
wenzelm@61337
    18
wenzelm@61337
    19
Command-line tool "isabelle update_theorems" updates theory sources
wenzelm@61337
    20
accordingly.
wenzelm@61337
    21
wenzelm@61338
    22
* Toplevel theorem statement 'proposition' is another alias for
wenzelm@61338
    23
'theorem'.
wenzelm@61338
    24
wenzelm@61579
    25
* Syntax for formal comments "-- text" now also supports the symbolic
wenzelm@61579
    26
form "\<comment> text". Command-line tool "isabelle update_cartouches -c" helps
wenzelm@61579
    27
to update old sources.
wenzelm@61579

*** Prover IDE -- Isabelle/Scala/jEdit ***
wenzelm@60610
    31
wenzelm@61600
    32
* Completion of symbols via prefix of \<name> or \<^name> or \name is
wenzelm@61600
    33
always possible, independently of the language context. It is never
wenzelm@61600
    34
implicit: a popup will show up unconditionally.
wenzelm@61600
    35
wenzelm@60610
    36
* Improved scheduling for urgent print tasks (e.g. command state output,
wenzelm@60610
    37
interactive queries) wrt. long-running background tasks.
wenzelm@60610
    38
wenzelm@60986
    39
* IDE support for the source-level debugger of Poly/ML, to work with
wenzelm@60984
    40
Isabelle/ML and official Standard ML. Configuration option "ML_debugger"
wenzelm@60984
    41
and commands 'ML_file_debug', 'ML_file_no_debug', 'SML_file_debug',
wenzelm@60984
    42
'SML_file_no_debug' control compilation of sources with debugging
wenzelm@60984
    43
information. The Debugger panel allows to set breakpoints (via context
wenzelm@60984
    44
menu), step through stopped threads, evaluate local ML expressions etc.
wenzelm@60984
    45
At least one Debugger view needs to be active to have any effect on the
wenzelm@60984
    46
running ML program.
wenzelm@60984
    47
wenzelm@61173
    48
* The main Isabelle executable is managed as single-instance Desktop
wenzelm@61173
    49
application uniformly on all platforms: Linux, Windows, Mac OS X.
wenzelm@61170
    50
wenzelm@61198
    51
* The text overview column (status of errors, warnings etc.) is updated
wenzelm@61198
    52
asynchronously, leading to much better editor reactivity. Moreover, the
wenzelm@61198
    53
full document node content is taken into account.
wenzelm@61198
    54
wenzelm@61218
    55
* The State panel manages explicit proof state output, with jEdit action
wenzelm@61218
    56
"isabelle.update-state" (shortcut S+ENTER) to trigger update according
wenzelm@61604
    57
to cursor position.
wenzelm@61604
    58
wenzelm@61604
    59
* The Output panel no longer shows proof state output by default. This
wenzelm@61604
    60
reduces resource requirements of prover time and GUI space.
wenzelm@61604
    61
INCOMPATIBILITY, use the State panel instead or enable option
wenzelm@61604
    62
"editor_output_state".
wenzelm@61215
    63
wenzelm@61483
    64
* Action "isabelle-emph" (with keyboard shortcut C+e LEFT) controls
wenzelm@61483
    65
emphasized text style; the effect is visible in document output, not in
wenzelm@61483
    66
the editor.
wenzelm@61483
    67
wenzelm@61483
    68
* Action "isabelle-reset" now uses keyboard shortcut C+e BACK_SPACE,
wenzelm@61483
    69
instead of former C+e LEFT.
wenzelm@61483
    70
wenzelm@61512
    71
* New command-line tool "isabelle jedit_client" allows to connect to
wenzelm@61512
    72
already running Isabelle/jEdit process. This achieves the effect of
wenzelm@61512
    73
single-instance applications seen on common GUI desktops.
wenzelm@61512
    74
wenzelm@61512
    75
* The command-line tool "isabelle jedit" and the isabelle.Main
wenzelm@61512
    76
application wrapper threat the default $USER_HOME/Scratch.thy more
wenzelm@61512
    77
uniformly, and allow the dummy file argument ":" to open an empty buffer
wenzelm@61512
    78
instead.
wenzelm@61512
    79
wenzelm@61529
    80
* The default look-and-feel for Linux is the traditional "Metal", which
wenzelm@61529
    81
works better with GUI scaling for very high-resolution displays (e.g.
wenzelm@61529
    82
4K). Moreover, it is generally more robust than "Nimbus".
wenzelm@61529
    83
wenzelm@60610
    84
wenzelm@61405
    85
*** Document preparation ***
wenzelm@61405
    86
wenzelm@61491
    87
* There is a new short form for antiquotations with a single argument
wenzelm@61491
    88
that is a cartouche: \<^name>\<open>...\<close> is equivalent to @{name \<open>...\<close>} and
wenzelm@61595
    89
\<open>...\<close> without control symbol is equivalent to @{cartouche \<open>...\<close>}.
wenzelm@61595
    90
\<^name> without following cartouche is equivalent to @{name}. The
wenzelm@61501
    91
standard Isabelle fonts provide glyphs to render important control
wenzelm@61501
    92
symbols, e.g. "\<^verbatim>", "\<^emph>", "\<^bold>".
wenzelm@61491
    93
wenzelm@61614
    94
* Antiquotation @{theory_text} prints uninterpreted theory source text
wenzelm@61653
    95
(outer syntax with command keywords etc.). This may be used in the short
wenzelm@61653
    96
form \<^theory_text>\<open>...\<close>.
wenzelm@61614
    97
wenzelm@61660
    98
* Antiquotation @{doc ENTRY} provides a reference to the given
wenzelm@61660
    99
documentation, with a hyperlink in the Prover IDE.
wenzelm@61660
   100
wenzelm@61623
   101
* Antiquotations @{command}, @{method}, @{attribute} print checked
wenzelm@61623
   102
entities of the Isar language.
wenzelm@61623
   103
wenzelm@61595
   104
* Antiquotations @{noindent}, @{smallskip}, @{medskip}, @{bigskip} with
wenzelm@61595
   105
corresponding control symbols \<^noindent>, \<^smallskip>, \<^medskip>, \<^bigskip> specify spacing formally, using
wenzelm@61595
   106
standard LaTeX macros of the same names.
wenzelm@61595
   107
wenzelm@61491
   108
* Antiquotation @{cartouche} in Isabelle/Pure is the same as @{text}.
wenzelm@61491
   109
Consequently, \<open>...\<close> without any decoration prints literal quasi-formal
wenzelm@61492
   110
text. Command-line tool "isabelle update_cartouches -t" helps to update
wenzelm@61492
   111
old sources, by approximative patching of the content of string and
wenzelm@61492
   112
cartouche tokens seen in theory sources.
wenzelm@61491
   113
wenzelm@61491
   114
* The @{text} antiquotation now ignores the antiquotation option
wenzelm@61491
   115
"source". The given text content is output unconditionally, without any
wenzelm@61491
   116
surrounding quotes etc. Subtle INCOMPATIBILITY, put quotes into the
wenzelm@61494
   117
argument where they are really intended, e.g. @{text \<open>"foo"\<close>}. Initial
wenzelm@61494
   118
or terminal spaces are ignored.
wenzelm@61491
   119
wenzelm@61471
   120
* HTML presentation uses the standard IsabelleText font and Unicode
wenzelm@61471
   121
rendering of Isabelle symbols like Isabelle/Scala/jEdit.  The former
wenzelm@61488
   122
print mode "HTML" loses its special meaning.
wenzelm@61471
   123
wenzelm@61463
   124
* Commands 'paragraph' and 'subparagraph' provide additional section
wenzelm@61463
   125
headings. Thus there are 6 levels of standard headings, as in HTML.
wenzelm@61463
   126
wenzelm@61463
   127
* Text is structured in paragraphs and nested lists, using notation that
wenzelm@61463
   128
is similar to Markdown. The control symbols for list items are as
wenzelm@61463
   129
follows:
wenzelm@61463
   130
wenzelm@61463
   131
  \<^item>  itemize
wenzelm@61463
   132
  \<^enum>  enumerate
wenzelm@61463
   133
  \<^descr>  description
wenzelm@61463
   134
wenzelm@61463
   135
* Command 'text_raw' has been clarified: input text is processed as in
wenzelm@61463
   136
'text' (with antiquotations and control symbols). The key difference is
wenzelm@61463
   137
the lack of the surrounding isabelle markup environment in output.
wenzelm@61405
   138
wenzelm@61473
   139
* Document antiquotations @{emph} and @{bold} output LaTeX source
wenzelm@61653
   140
recursively, adding appropriate text style markup. These may be used in
wenzelm@61653
   141
the short form \<^emph>\<open>...\<close> and \<^bold>\<open>...\<close>.
wenzelm@61473
   142
wenzelm@61571
   143
* Document antiquotation @{footnote} outputs LaTeX source recursively,
wenzelm@61653
   144
marked as \footnote{}. This may be used in the short form \<^footnote>\<open>...\<close>.
wenzelm@61571
   145
wenzelm@61405
   146
wenzelm@60406
   147
*** Isar ***
wenzelm@60406
   148
wenzelm@60406
   149
* Command 'obtain' binds term abbreviations (via 'is' patterns) in the
wenzelm@60406
   150
proof body as well, abstracted over relevant parameters.
wenzelm@60406
   151
wenzelm@60477
   152
* Improved type-inference for theorem statement 'obtains': separate
wenzelm@60477
   153
parameter scope for of each clause.
wenzelm@60477
   154
wenzelm@60408
   155
* Term abbreviations via 'is' patterns also work for schematic
wenzelm@60408
   156
statements: result is abstracted over unknowns.
wenzelm@60408
   157
wenzelm@60414
   158
* Local goals ('have', 'show', 'hence', 'thus') allow structured
wenzelm@60414
   159
statements like fixes/assumes/shows in theorem specifications, but the
wenzelm@60555
   160
notation is postfix with keywords 'if' (or 'when') and 'for'. For
wenzelm@60555
   161
example:
wenzelm@60414
   162
wenzelm@60414
   163
  have result: "C x y"
wenzelm@60414
   164
    if "A x" and "B y"
wenzelm@60414
   165
    for x :: 'a and y :: 'a
wenzelm@60414
   166
    <proof>
wenzelm@60414
   167
wenzelm@60449
   168
The local assumptions are bound to the name "that". The result is
wenzelm@60449
   169
exported from context of the statement as usual. The above roughly
wenzelm@60414
   170
corresponds to a raw proof block like this:
wenzelm@60414
   171
wenzelm@60414
   172
  {
wenzelm@60414
   173
    fix x :: 'a and y :: 'a
wenzelm@60449
   174
    assume that: "A x" "B y"
wenzelm@60414
   175
    have "C x y" <proof>
wenzelm@60414
   176
  }
wenzelm@60414
   177
  note result = this
wenzelm@60406
   178
wenzelm@60555
   179
The keyword 'when' may be used instead of 'if', to indicate 'presume'
wenzelm@60555
   180
instead of 'assume' above.
wenzelm@60555
   181
wenzelm@61658
   182
* Assumptions ('assume', 'presume') allow structured statements using
wenzelm@61658
   183
'if' and 'for', similar to 'have' etc. above. For example:
wenzelm@61658
   184
wenzelm@61658
   185
  assume result: "C x y"
wenzelm@61658
   186
    if "A x" and "B y"
wenzelm@61658
   187
    for x :: 'a and y :: 'a
wenzelm@61658
   188
wenzelm@61658
   189
This assumes "\<And>x y::'a. A x \<Longrightarrow> B y \<Longrightarrow> C x y" and produces a general
wenzelm@61658
   190
result as usual: "A ?x \<Longrightarrow> B ?y \<Longrightarrow> C ?x ?y".
wenzelm@61658
   191
wenzelm@61658
   192
Vacuous quantification in assumptions is omitted, i.e. a for-context
wenzelm@61658
   193
only effects propositions according to actual use of variables. For
wenzelm@61658
   194
example:
wenzelm@61658
   195
wenzelm@61658
   196
  assume "A x" and "B y" for x and y
wenzelm@61658
   197
wenzelm@61658
   198
is equivalent to:
wenzelm@61658
   199
wenzelm@61658
   200
  assume "\<And>x. A x" and "\<And>y. B y"
wenzelm@61658
   201
wenzelm@60595
   202
* The meaning of 'show' with Pure rule statements has changed: premises
wenzelm@60595
   203
are treated in the sense of 'assume', instead of 'presume'. This means,
wenzelm@60595
   204
a goal like "\<And>x. A x \<Longrightarrow> B x \<Longrightarrow> C x" can be solved completely as follows:
wenzelm@60595
   205
wenzelm@60595
   206
  show "\<And>x. A x \<Longrightarrow> B x \<Longrightarrow> C x"
wenzelm@60595
   207
wenzelm@60595
   208
or:
wenzelm@60595
   209
wenzelm@60595
   210
  show "C x" if "A x" "B x" for x
wenzelm@60595
   211
wenzelm@60595
   212
Rare INCOMPATIBILITY, the old behaviour may be recovered as follows:
wenzelm@60595
   213
wenzelm@60595
   214
  show "C x" when "A x" "B x" for x
wenzelm@60595
   215
wenzelm@60406
   216
* New command 'supply' supports fact definitions during goal refinement
wenzelm@60406
   217
('apply' scripts).
wenzelm@60406
   218
wenzelm@60459
   219
* New command 'consider' states rules for generalized elimination and
wenzelm@60459
   220
case splitting. This is like a toplevel statement "theorem obtains" used
wenzelm@60459
   221
within a proof body; or like a multi-branch 'obtain' without activation
wenzelm@60459
   222
of the local context elements yet.
wenzelm@60459
   223
wenzelm@60455
   224
* Proof method "cases" allows to specify the rule as first entry of
wenzelm@60455
   225
chained facts.  This is particularly useful with 'consider':
wenzelm@60455
   226
wenzelm@60455
   227
  consider (a) A | (b) B | (c) C <proof>
wenzelm@60455
   228
  then have something
wenzelm@60455
   229
  proof cases
wenzelm@60455
   230
    case a
wenzelm@60455
   231
    then show ?thesis <proof>
wenzelm@60455
   232
  next
wenzelm@60455
   233
    case b
wenzelm@60455
   234
    then show ?thesis <proof>
wenzelm@60455
   235
  next
wenzelm@60455
   236
    case c
wenzelm@60455
   237
    then show ?thesis <proof>
wenzelm@60455
   238
  qed
wenzelm@60455
   239
wenzelm@60565
   240
* Command 'case' allows fact name and attribute specification like this:
wenzelm@60565
   241
wenzelm@60565
   242
  case a: (c xs)
wenzelm@60565
   243
  case a [attributes]: (c xs)
wenzelm@60565
   244
wenzelm@60565
   245
Facts that are introduced by invoking the case context are uniformly
wenzelm@60565
   246
qualified by "a"; the same name is used for the cumulative fact. The old
wenzelm@60565
   247
form "case (c xs) [attributes]" is no longer supported. Rare
wenzelm@60565
   248
INCOMPATIBILITY, need to adapt uses of case facts in exotic situations,
wenzelm@60565
   249
and always put attributes in front.
wenzelm@60565
   250
wenzelm@60618
   251
* The standard proof method of commands 'proof' and '..' is now called
wenzelm@60618
   252
"standard" to make semantically clear what it is; the old name "default"
wenzelm@60618
   253
is still available as legacy for some time. Documentation now explains
wenzelm@60618
   254
'..' more accurately as "by standard" instead of "by rule".
wenzelm@60618
   255
wenzelm@60631
   256
* Command 'subgoal' allows to impose some structure on backward
wenzelm@60631
   257
refinements, to avoid proof scripts degenerating into long of 'apply'
wenzelm@60631
   258
sequences. Further explanations and examples are given in the isar-ref
wenzelm@60631
   259
manual.
wenzelm@60631
   260
wenzelm@61166
   261
* Proof method "goal_cases" turns the current subgoals into cases within
wenzelm@61166
   262
the context; the conclusion is bound to variable ?case in each case. For
wenzelm@61166
   263
example:
wenzelm@60617
   264
wenzelm@60617
   265
lemma "\<And>x. A x \<Longrightarrow> B x \<Longrightarrow> C x"
wenzelm@60622
   266
  and "\<And>y z. U y \<Longrightarrow> V z \<Longrightarrow> W y z"
wenzelm@61166
   267
proof goal_cases
wenzelm@60622
   268
  case (1 x)
wenzelm@60622
   269
  then show ?case using \<open>A x\<close> \<open>B x\<close> sorry
wenzelm@60622
   270
next
wenzelm@60622
   271
  case (2 y z)
wenzelm@60622
   272
  then show ?case using \<open>U y\<close> \<open>V z\<close> sorry
wenzelm@60622
   273

* The undocumented feature of implicit cases goal1, goal2, goal3, etc.
wenzelm@60617
   286
is marked as legacy, and will be removed eventually. The proof method
wenzelm@60617
   287
"goals" achieves a similar effect within regular Isar; often it can be
wenzelm@60617
   288
done more adequately by other means (e.g. 'consider').
wenzelm@60581
   289
wenzelm@60551

all its context sections (as indicated via 'next'). This is e.g.

wenzelm@61308
   391
* Commands 'inductive' and 'inductive_set' work better when names for
wenzelm@61308
   392
intro rules are omitted: the "cases" and "induct" rules no longer
wenzelm@61308
   393
declare empty case_names, but no case_names at all. This allows to use
wenzelm@61308
   394
numbered cases in proofs, without requiring method "goal_cases".
wenzelm@61308
   395
wenzelm@61269
   396
* The 'typedef' command has been upgraded from a partially checked
wenzelm@61269
   397
"axiomatization", to a full definitional specification that takes the
wenzelm@61269
   398
global collection of overloaded constant / type definitions into
wenzelm@61269
   399
account. Type definitions with open dependencies on overloaded
wenzelm@61269
   400
definitions need to be specified as "typedef (overloaded)". This
wenzelm@61269
   401
provides extra robustness in theory construction. Rare INCOMPATIBILITY.
wenzelm@61269
   402
wenzelm@61118

* Qualification of various formal entities in the libraries is done more
wenzelm@61118
   404
uniformly via "context begin qualified definition ... end" instead of
wenzelm@61118
   405
old-style "hide_const (open) ...". Consequently, both the defined
wenzelm@61118
   406
constant and its defining fact become qualified, e.g. Option.is_none and
wenzelm@61118
   407
Option.is_none_def. Occasional INCOMPATIBILITY in applications.
wenzelm@61118
   408
wenzelm@61069
   409
* Some old and rarely used ASCII replacement syntax has been removed.
wenzelm@61069
   410
INCOMPATIBILITY, standard syntax with symbols should be used instead.
wenzelm@61069
   411
The subsequent commands help to reproduce the old forms, e.g. to

   426
wenzelm@61143

   441
    cases where Sledgehammer gives a proof that does not work.
blanchet@60306
   442
  - Auto Sledgehammer now minimizes and preplays the results.
blanchet@61030
   443
  - Handle Vampire 4.0 proof output without raising exception.

   444
  - Eliminated "MASH" environment variable. Use the "MaSh" option in
blanchet@61043
   445

   450
  - Fixed soundness bug in "destroy_constrs" optimization.
blanchet@60310
   451

   452
  - Eliminated obsolete "blocking" option.

blanchet@61345
   456
    structure on the raw type to an abstract type defined using typedef.
blanchet@61345
   457
  - Always generate "case_transfer" theorem.
blanchet@61551
   458
  - Allow discriminators and selectors with the same name as the type
blanchet@61551
   459
    being defined.
blanchet@61551
   460
  - Avoid various internal name clashes (e.g., 'datatype f = f').

   474
haftmann@60688
   475
* Class algebraic_semidom introduces common algebraic notions of
haftmann@60688
   476
integral (semi)domains, particularly units.  Although
haftmann@60517
   477
logically subsumed by fields, is is not a super class of these
haftmann@60517
   478
in order not to burden fields with notions that are trivial there.
haftmann@60688
   479
haftmann@60688

   484
* Abstract specification of gcd/lcm operations in classes semiring_gcd,
haftmann@60688

semiring_Gcd, semiring_Lcd.  Minor INCOMPATIBILITY: facts gcd_nat.commute
haftmann@60688
   486
and gcd_int.commute are subsumed by gcd.commute, as well as gcd_nat.assoc
haftmann@60688
   487
and gcd_int.assoc by gcd.assoc.
haftmann@60517
   488
haftmann@60429
   489
* Former constants Fields.divide (_ / _) and Divides.div (_ div _)
haftmann@60352
   490
are logically unified to Rings.divide in syntactic type class
haftmann@60429
   491
Rings.divide, with infix syntax (_ div _).  Infix syntax (_ / _)
haftmann@60429
   492
for field division is added later as abbreviation in class Fields.inverse.
haftmann@60516
   493
INCOMPATIBILITY,  instantiations must refer to Rings.divide rather
haftmann@60429
   494
than the former separate constants, hence infix syntax (_ / _) is usually
haftmann@60429
   495
not available during instantiation.
haftmann@60352
   496
Andreas@61629
   497
* New cancellation simprocs for boolean algebras to cancel
Andreas@61629
   498
complementary terms for sup and inf. For example, "sup x (sup y (- x))"
Andreas@61629
   499
simplifies to "top". INCOMPATIBILITY.

Simplifier.make_simproc and Simplifier.define_simproc supersede various
wenzelm@61144
   565
forms of Simplifier.mk_simproc, Simplifier.simproc_global etc. Note that

* Instantiation rules have been re-organized as follows:
wenzelm@60802
   570
wenzelm@60802
   571
  Thm.instantiate  (*low-level instantiation with named arguments*)
wenzelm@60802

  Drule.infer_instantiate'  (*version with positional arguments*)
wenzelm@60802
   576
wenzelm@60802
   577
The LHS only requires variable specifications, instead of full terms.
wenzelm@60802
   578
Old cterm_instantiate is superseded by infer_instantiate.

   581
* Old tactic shorthands atac, rtac, etac, dtac, ftac have been
wenzelm@60793
   582
discontinued. INCOMPATIBILITY, use regular assume_tac, resolve_tac etc.
wenzelm@60793
   583
instead (with proper context).
wenzelm@60642
   584
wenzelm@60642
   585
* Thm.instantiate (and derivatives) no longer require the LHS of the
wenzelm@60642

wenzelm@60642
   587
wenzelm@60707
   588
* Subgoal.SUBPROOF and Subgoal.FOCUS combinators use anonymous
wenzelm@60707
   589
quasi-bound variables (like the Simplifier), instead of accidentally
wenzelm@60707
   590
named local fixes. This has the potential to improve stability of proof
wenzelm@60707
   591
tools, but can also cause INCOMPATIBILITY for tools that don't observe
wenzelm@60707

wenzelm@61216
   611

wenzelm@59939
   651
* Local theory specification commands may have a 'private' or
wenzelm@59990
   652
'qualified' modifier to restrict name space accesses to the local scope,
wenzelm@59939
   653
as provided by some "context begin ... end" block. For example:
wenzelm@59926
   654
wenzelm@59926

wenzelm@59926
   656

* Command 'experiment' opens an anonymous locale context with private
wenzelm@59901
   670
naming policy.
wenzelm@59901
   671
wenzelm@59951
   672
* Command 'notepad' requires proper nesting of begin/end and its proof
wenzelm@59951
   673
structure in the body: 'oops' is no longer supported here. Minor
wenzelm@59951
   674
INCOMPATIBILITY, use 'sorry' instead.
wenzelm@59951
   675
wenzelm@59951
   676
* Command 'named_theorems' declares a dynamic fact within the context,
wenzelm@59951
   677
together with an attribute to maintain the content incrementally. This
wenzelm@59951
   678
supersedes functor Named_Thms in Isabelle/ML, but with a subtle change
wenzelm@59951
   679
of semantics due to external visual order vs. internal reverse order.
wenzelm@59951
   680
wenzelm@59951
   681
* 'find_theorems': search patterns which are abstractions are
wenzelm@59951
   682
schematically expanded before search. Search results match the naive
wenzelm@59951
   683
expectation more closely, particularly wrt. abbreviations.
wenzelm@59951
   684
INCOMPATIBILITY.
wenzelm@59648
   685
wenzelm@59569
   686
* Commands 'method_setup' and 'attribute_setup' now work within a local
wenzelm@59569
   687
theory context.
wenzelm@57941
   688
wenzelm@58928
   689
* Outer syntax commands are managed authentically within the theory
wenzelm@59569
   690
context, without implicit global state. Potential for accidental
wenzelm@58928
   691
INCOMPATIBILITY, make sure that required theories are really imported.
wenzelm@58928
   692
wenzelm@60115
   693
* Historical command-line terminator ";" is no longer accepted (and
wenzelm@60115
   694
already used differently in Isar). Minor INCOMPATIBILITY, use "isabelle
wenzelm@60115
   695
update_semicolons" to remove obsolete semicolons from old theory
wenzelm@60115
   696
sources.
wenzelm@60115
   697
wenzelm@59951
   698
* Structural composition of proof methods (meth1; meth2) in Isar
wenzelm@59951

corresponds to (tac1 THEN_ALL_NEW tac2) in ML.
haftmann@59105
   700
wenzelm@60119
   701
* The Eisbach proof method language allows to define new proof methods
wenzelm@60119
   702
by combining existing ones with their usual syntax. The "match" proof
wenzelm@60119
   703
method provides basic fact/term matching in addition to
wenzelm@60119
   704
premise/conclusion matching through Subgoal.focus, and binds fact names
wenzelm@60288
   705
from matches as well as term patterns within matches. The Isabelle
wenzelm@60288
   706
documentation provides an entry "eisbach" for the Eisbach User Manual.

* Improved folding mode "isabelle" based on Isar syntax. Alternatively,
wenzelm@59569
   713
the "sidekick" mode may be used for document structure.
wenzelm@59569
   714
wenzelm@59569
   715
* Extended bracket matching based on Isar language structure. System
wenzelm@59569
   716
option jedit_structure_limit determines maximum number of lines to scan
wenzelm@59569
   717
in the buffer.
wenzelm@58758
   718
wenzelm@58540
   719
* Support for BibTeX files: context menu, context-sensitive token
wenzelm@58540
   720
marker, SideKick parser.
wenzelm@58524
   721
wenzelm@58551
   722
* Document antiquotation @{cite} provides formal markup, which is
wenzelm@60265
   723
interpreted semi-formally based on .bib files that happen to be open in
wenzelm@60265
   724
the editor (hyperlinks, completion etc.).
wenzelm@58551
   725
wenzelm@58785
   726
* Less waste of vertical space via negative line spacing (see Global
wenzelm@58785
   727
Options / Text Area).
wenzelm@58785
   728
wenzelm@60089
   729
* Improved graphview panel with optional output of PNG or PDF, for
wenzelm@60273
   730
display of 'thy_deps', 'class_deps' etc.
wenzelm@60009
   731
wenzelm@60115
   732
* The commands 'thy_deps' and 'class_deps' allow optional bounds to
wenzelm@60115
   733
restrict the visualized hierarchy.
wenzelm@60093
   734
wenzelm@60072
   735
* Improved scheduling for asynchronous print commands (e.g. provers
wenzelm@60072
   736
managed by the Sledgehammer panel) wrt. ongoing document processing.

*** Document preparation ***
wenzelm@59951
   740
wenzelm@59951
   741
* Document markup commands 'chapter', 'section', 'subsection',
wenzelm@59951
   742
'subsubsection', 'text', 'txt', 'text_raw' work uniformly in any
wenzelm@59951
   743
context, even before the initial 'theory' command. Obsolete proof
wenzelm@59951
   744
commands 'sect', 'subsect', 'subsubsect', 'txt_raw' have been
wenzelm@59951
   745
discontinued, use 'section', 'subsection', 'subsubsection', 'text_raw'
wenzelm@59951
   746
instead. The old 'header' command is still retained for some time, but
wenzelm@59951
   747
should be replaced by 'chapter', 'section' etc. (using "isabelle
wenzelm@59951
   748
update_header"). Minor INCOMPATIBILITY.
wenzelm@59951
   749
wenzelm@60009
   750
* Official support for "tt" style variants, via \isatt{...} or
wenzelm@60009
   751
\begin{isabellett}...\end{isabellett}. The somewhat fragile \verb or
wenzelm@60009
   752
verbatim environment of LaTeX is no longer used. This allows @{ML} etc.
wenzelm@60009
   753
as argument to other macros (such as footnotes).
wenzelm@60009
   754
wenzelm@60009
   755
* Document antiquotation @{verbatim} prints ASCII text literally in "tt"
wenzelm@60009
   756
style.
wenzelm@60009
   757
wenzelm@60009
   758
* Discontinued obsolete option "document_graph": session_graph.pdf is
wenzelm@60009
   759
produced unconditionally for HTML browser_info and PDF-LaTeX document.
wenzelm@60009
   760
wenzelm@59951
   761
* Diagnostic commands and document markup commands within a proof do not
wenzelm@59951
   762
affect the command tag for output. Thus commands like 'thm' are subject
wenzelm@59951
   763
to proof document structure, and no longer "stick out" accidentally.
wenzelm@59951
   764
Commands 'text' and 'txt' merely differ in the LaTeX style, not their
wenzelm@59951
   765
tags. Potential INCOMPATIBILITY in exotic situations.
wenzelm@59951
   766
wenzelm@59951
   767
* System option "pretty_margin" is superseded by "thy_output_margin",
wenzelm@59951
   768
which is also accessible via document antiquotation option "margin".
wenzelm@59951
   769
Only the margin for document output may be changed, but not the global
wenzelm@59951
   770
pretty printing: that is 76 for plain console output, and adapted
wenzelm@59951
   771
dynamically in GUI front-ends. Implementations of document
wenzelm@59951
   772
antiquotations need to observe the margin explicitly according to
wenzelm@59951
   773
Thy_Output.string_of_margin. Minor INCOMPATIBILITY.
wenzelm@59951
   774
wenzelm@60299
   775
* Specification of 'document_files' in the session ROOT file is
wenzelm@60299
   776
mandatory for document preparation. The legacy mode with implicit
wenzelm@60299
   777
copying of the document/ directory is no longer supported. Minor

wenzelm@59835
   783
* Proof methods with explicit instantiation ("rule_tac", "subgoal_tac"
wenzelm@59835
   784
etc.) allow an optional context of local variables ('for' declaration):
wenzelm@59835
   785
these variables become schematic in the instantiated theorem; this
wenzelm@59835
   786
behaviour is analogous to 'for' in attributes "where" and "of".
wenzelm@59835
   787
Configuration option rule_insts_schematic (default false) controls use
wenzelm@59835
   788
of schematic variables outside the context. Minor INCOMPATIBILITY,
wenzelm@59835
   789
declare rule_insts_schematic = true temporarily and update to use local
wenzelm@59835
   790
variable declarations or dummy patterns instead.
wenzelm@59835
   791
wenzelm@60009
   792
* Explicit instantiation via attributes "where", "of", and proof methods
wenzelm@60009
   793
"rule_tac" with derivatives like "subgoal_tac" etc. admit dummy patterns
wenzelm@60009
   794
("_") that stand for anonymous local variables.
wenzelm@60009
   795
wenzelm@59951
   796
* Generated schematic variables in standard format of exported facts are
wenzelm@59951
   797
incremented to avoid material in the proof context. Rare
wenzelm@59951
   798
INCOMPATIBILITY, explicit instantiation sometimes needs to refer to
wenzelm@59951
   799
different index.
wenzelm@59951

wenzelm@60010
   801
* Lexical separation of signed and unsigned numerals: categories "num"
wenzelm@60010
   802
and "float" are unsigned. INCOMPATIBILITY: subtle change in precedence
wenzelm@60010
   803
of numeral signs, particularly in expressions involving infix syntax
wenzelm@60010
   804
like "(- 1) ^ n".
haftmann@58410
   805
wenzelm@58421
   806
* Old inner token category "xnum" has been discontinued.  Potential
wenzelm@58421

blanchet@58044
   839
    INCOMPATIBILITY.
blanchet@58044

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

    attribute. This can influence the behavior of the "cases" proof
blanchet@57990
   842
    method when more than one case rule is applicable (e.g., an
blanchet@57990
   843
    assumption is of the form "w : set ws" and the method "cases w"
blanchet@57990
   844
    is invoked). The solution is to specify the case rule explicitly
blanchet@57990
   845

   856
    option) is now performed by the BNF package. Theories Lifting_Sum,
wenzelm@60114
   857
    Lifting_Product and Lifting_Option from Main became obsolete and
wenzelm@60114
   858
    were removed. Changed definitions of the relators rel_prod and

   860
    INCOMPATIBILITY: use rel_prod.simps and rel_sum.simps instead
wenzelm@60114

wenzelm@60114
   862
    Minor INCOMPATIBILITY: (rarely used by name) transfer theorem names
wenzelm@60114

  - Fixed soundness bug related to the strict and non-strict subset
blanchet@59039
   884
    operations.
blanchet@59039
   885
blanchet@57737
   886
* Sledgehammer:
blanchet@59511
   887
  - CVC4 is now included with Isabelle instead of CVC3 and run by
blanchet@59511
   888
    default.
blanchet@59965
   889
  - Z3 is now always enabled by default, now that it is fully open
blanchet@59965
   890
    source. The "z3_non_commercial" option is discontinued.
blanchet@57737
   891
  - Minimization is now always enabled by default.
wenzelm@60010
   892
    Removed sub-command:
blanchet@57737
   893
      min
blanchet@59967
   894
  - Proof reconstruction, both one-liners and Isar, has been
blanchet@59039

* Old and new SMT modules:
blanchet@58067
   899
  - The old 'smt' method has been renamed 'old_smt' and moved to
wenzelm@59569
   900
    'src/HOL/Library/Old_SMT.thy'. It is provided for compatibility,
wenzelm@59569
   901
    until applications have been ported to use the new 'smt' method. For
wenzelm@59569
   902
    the method to work, an older version of Z3 (e.g. Z3 3.2 or 4.0) must
wenzelm@59569
   903
    be installed, and the environment variable "OLD_Z3_SOLVER" must

boehmes@59216
   910
  - New option 'smt_statistics' to display statistics of the new 'smt'

   911
    method, especially runtime statistics of Z3 proof reconstruction.
blanchet@58060

* Lifting: command 'lift_definition' allows to execute lifted constants
wenzelm@60261
   914
that have as a return type a datatype containing a subtype. This
wenzelm@60261
   915
overcomes long-time limitations in the area of code generation and
wenzelm@60261
   916
lifting, and avoids tedious workarounds.
kuncar@60258
   917
wenzelm@60009
   918
* Command and antiquotation "value" provide different evaluation slots
wenzelm@60009
   919
(again), where the previous strategy (NBE after ML) serves as default.
wenzelm@60009
   920
Minor INCOMPATIBILITY.
wenzelm@60009
   921
wenzelm@60009
   922
* Add NO_MATCH-simproc, allows to check for syntactic non-equality.
wenzelm@60009
   923
wenzelm@60009
   924
* field_simps: Use NO_MATCH-simproc for distribution rules, to avoid
wenzelm@60009
   925
non-termination in case of distributing a division. With this change
wenzelm@60009
   926
field_simps is in some cases slightly less powerful, if it fails try to
wenzelm@60009
   927
add algebra_simps, or use divide_simps. Minor INCOMPATIBILITY.
wenzelm@60009
   928
wenzelm@60009
   929
* Separate class no_zero_divisors has been given up in favour of fully
wenzelm@60009
   930
algebraic semiring_no_zero_divisors. INCOMPATIBILITY.
wenzelm@60009

INCOMPATIBILITY.
wenzelm@60009

wenzelm@60009
   935

wenzelm@60009
   936
"inverse 0 = 0". Given up separate classes division_ring_inverse_zero,
wenzelm@60009
   937
field_inverse_zero and linordered_field_inverse_zero. INCOMPATIBILITY.
wenzelm@60009
   938
wenzelm@60009
   939

   940
additive inverse operation. INCOMPATIBILITY.
wenzelm@60009
   941
lp15@60020
   942
* Complex powers and square roots. The functions "ln" and "powr" are now
wenzelm@60025
   943
overloaded for types real and complex, and 0 powr y = 0 by definition.
wenzelm@60025
   944
INCOMPATIBILITY: type constraints may be necessary.
lp15@60020
   945
wenzelm@60009
   946
* The functions "sin" and "cos" are now defined for any type of sort
wenzelm@60009
   947
"{real_normed_algebra_1,banach}" type, so in particular on "real" and
wenzelm@60009
   948
"complex" uniformly. Minor INCOMPATIBILITY: type constraints may be
wenzelm@60009
   949
needed.
wenzelm@60009
   950
wenzelm@60009
   951
* New library of properties of the complex transcendental functions sin,
wenzelm@60009
   952
cos, tan, exp, Ln, Arctan, Arcsin, Arccos. Ported from HOL Light.
wenzelm@60009
   953
wenzelm@60009
   954
* The factorial function, "fact", now has type "nat => 'a" (of a sort
wenzelm@60009
   955
that admits numeric types including nat, int, real and complex.
wenzelm@60009
   956
INCOMPATIBILITY: an expression such as "fact 3 = 6" may require a type
wenzelm@60009
   957
constraint, and the combination "real (fact k)" is likely to be
wenzelm@60009
   958
unsatisfactory. If a type conversion is still necessary, then use
wenzelm@60009
   959
"of_nat (fact k)" or "real_of_nat (fact k)".
wenzelm@60009
   960
wenzelm@60009
   961
* Removed functions "natfloor" and "natceiling", use "nat o floor" and
wenzelm@60009
   962
"nat o ceiling" instead. A few of the lemmas have been retained and
wenzelm@60009
   963
adapted: in their names "natfloor"/"natceiling" has been replaced by
wenzelm@60009
   964
"nat_floor"/"nat_ceiling".
wenzelm@60009
   965
wenzelm@60009
   966
* Qualified some duplicated fact names required for boostrapping the
wenzelm@60009
   967
type class hierarchy:
wenzelm@60009
   968
  ab_add_uminus_conv_diff ~> diff_conv_add_uminus
wenzelm@60009
   969
  field_inverse_zero ~> inverse_zero
wenzelm@60009

  field_divide_inverse ~> divide_inverse
wenzelm@60009

wenzelm@60009
   972
Minor INCOMPATIBILITY.
wenzelm@60009
   973
wenzelm@60009
   974
* Eliminated fact duplicates:
wenzelm@60009
   975
  mult_less_imp_less_right ~> mult_right_less_imp_less
wenzelm@60009
   976
  mult_less_imp_less_left ~> mult_left_less_imp_less
wenzelm@60009
   977
Minor INCOMPATIBILITY.
wenzelm@60009
   978
wenzelm@60009
   979
* Fact consolidation: even_less_0_iff is subsumed by
wenzelm@60009
   980
double_add_less_zero_iff_single_add_less_zero (simp by default anyway).
wenzelm@60009
   981
wenzelm@60009
   982
* Generalized and consolidated some theorems concerning divsibility:
wenzelm@60009

wenzelm@60009
   984
  dvd_plus_eq_right ~> dvd_add_right_iff

wenzelm@60009
   986
Minor INCOMPATIBILITY.
wenzelm@60009

wenzelm@60009
   991
INCOMPATIBILITY.
wenzelm@60009

   994
INCOMPATIBILITY.
wenzelm@60009
   995
wenzelm@60009
   996
* Bootstrap of listsum as special case of abstract product over lists.
wenzelm@60009
   997
Fact rename:

   998
    listsum_def ~> listsum.eq_foldr

   999
INCOMPATIBILITY.
wenzelm@60009

wenzelm@60009
  1001
* Product over lists via constant "listprod".
wenzelm@60009
  1002
wenzelm@60009
  1003

wenzelm@59569
  1007
generated code in target languages in HOL/Library/Code_Test. See
wenzelm@59569

* Library/Multiset:
blanchet@59813
  1011
  - Introduced "replicate_mset" operation.
blanchet@59813
  1012
  - Introduced alternative characterizations of the multiset ordering in
blanchet@59813
  1013
    "Library/Multiset_Order".
blanchet@59958

* Library/Sum_of_Squares: simplified and improved "sos" method. Always
wenzelm@60009
  1042
use local CSDP executable, which is much faster than the NEOS server.
wenzelm@60009
  1043
The "sos_cert" functionality is invoked as "sos" with additional

* HOL-Decision_Procs: New counterexample generator quickcheck
wenzelm@60009
  1047
[approximation] for inequalities of transcendental functions. Uses
wenzelm@60009
  1048
hardware floating point arithmetic to randomly discover potential

* HOL-Probability: Reworked measurability prover
wenzelm@60010
  1054
  - applies destructor rules repeatedly
hoelzl@59354
  1055
  - removed application splitting (replaced by destructor rule)
wenzelm@59569

wenzelm@60009
  1065
* Subtle change of name space policy: undeclared entries are now
wenzelm@60009
  1066
considered inaccessible, instead of accessible via the fully-qualified
wenzelm@60009
  1067
internal name. This mainly affects Name_Space.intern (and derivatives),
wenzelm@60009
  1068
which may produce an unexpected Long_Name.hidden prefix. Note that
wenzelm@60010
  1069
contemporary applications use the strict Name_Space.check (and
wenzelm@60009
  1070
derivatives) instead, which is not affected by the change. Potential
wenzelm@60009
  1071
INCOMPATIBILITY in rare applications of Name_Space.intern.
wenzelm@59951

  1077
as parameterized antiquotations, e.g. @{map 4} for lists of quadruples.
wenzelm@59951
  1078
wenzelm@59951
  1079
* Renamed "pairself" to "apply2", in accordance to @{apply 2}.
wenzelm@59951
  1080
INCOMPATIBILITY.
wenzelm@59951
  1081
wenzelm@59951
  1082
* Former combinators NAMED_CRITICAL and CRITICAL for central critical
wenzelm@59951
  1083
sections have been discontinued, in favour of the more elementary
wenzelm@59951
  1084
Multithreading.synchronized and its high-level derivative
wenzelm@59951
  1085
Synchronized.var (which is usually sufficient in applications). Subtle
wenzelm@59951
  1086
INCOMPATIBILITY: synchronized access needs to be atomic and cannot be
wenzelm@59951
  1087
nested.
wenzelm@59951
  1088
wenzelm@60009
  1089
* Synchronized.value (ML) is actually synchronized (as in Scala): subtle
wenzelm@60009
  1090
change of semantics with minimal potential for INCOMPATIBILITY.
wenzelm@59899
  1091
wenzelm@59621
  1092
* The main operations to certify logical entities are Thm.ctyp_of and
wenzelm@59621
  1093
Thm.cterm_of with a local context; old-style global theory variants are
wenzelm@59621
  1094
available as Thm.global_ctyp_of and Thm.global_cterm_of.
wenzelm@59621
  1095
INCOMPATIBILITY.
wenzelm@59621
  1096
wenzelm@59582
  1097
* Elementary operations in module Thm are no longer pervasive.
wenzelm@59582
  1098
INCOMPATIBILITY, need to use qualified Thm.prop_of, Thm.cterm_of,
wenzelm@59582
  1099
Thm.term_of etc.
wenzelm@59582
  1100
wenzelm@58963
  1101
* Proper context for various elementary tactics: assume_tac,
wenzelm@59498
  1102
resolve_tac, eresolve_tac, dresolve_tac, forward_tac, match_tac,
wenzelm@59498
  1103
compose_tac, Splitter.split_tac etc. INCOMPATIBILITY.
wenzelm@58956
  1104
blanchet@58066
  1105
* Tactical PARALLEL_ALLGOALS is the most common way to refer to
blanchet@58066
  1106
PARALLEL_GOALS.
blanchet@58066
  1107
wenzelm@59564
  1108
* Goal.prove_multi is superseded by the fully general Goal.prove_common,
wenzelm@59564
  1109
which also allows to specify a fork priority.
wenzelm@59564
  1110
wenzelm@59936
  1111
* Antiquotation @{command_spec "COMMAND"} is superseded by
wenzelm@59936
  1112
@{command_keyword COMMAND} (usually without quotes and with PIDE
wenzelm@59936
  1113
markup). Minor INCOMPATIBILITY.
wenzelm@59936
  1114
wenzelm@60009
  1115
* Cartouches within ML sources are turned into values of type
wenzelm@60009
  1116
Input.source (with formal position information).

*** System ***
wenzelm@58610
  1120
wenzelm@59951
  1121
* The Isabelle tool "update_cartouches" changes theory files to use
wenzelm@59951
  1122
cartouches instead of old-style {* verbatim *} or `alt_string` tokens.
wenzelm@59951
  1123
wenzelm@60106
  1124
* The Isabelle tool "build" provides new options -X, -k, -x.
wenzelm@59951
  1125
wenzelm@59951
  1126
* Discontinued old-fashioned "codegen" tool. Code generation can always
wenzelm@59951
  1127
be externally triggered using an appropriate ROOT file plus a
wenzelm@59951
  1128
corresponding theory. Parametrization is possible using environment
wenzelm@59951
  1129
variables, or ML snippets in the most extreme cases. Minor
wenzelm@59951
  1130
INCOMPATIBILITY.
wenzelm@58842
  1131
wenzelm@59200
  1132
* JVM system property "isabelle.threads" determines size of Scala thread
wenzelm@59200
  1133
pool, like Isabelle system option "threads" for ML.
wenzelm@59200
  1134
wenzelm@59201
  1135
* JVM system property "isabelle.laf" determines the default Swing
wenzelm@59201
  1136
look-and-feel, via internal class name or symbolic name as in the jEdit
wenzelm@59201
  1137
menu Global Options / Appearance.
wenzelm@59201
  1138
wenzelm@59951

wenzelm@54702
  1147
*** General ***
wenzelm@54702
  1148
wenzelm@57452
  1149
* Support for official Standard ML within the Isabelle context.
wenzelm@57452
  1150
Command 'SML_file' reads and evaluates the given Standard ML file.
wenzelm@57452
  1151
Toplevel bindings are stored within the theory context; the initial
wenzelm@57452
  1152
environment is restricted to the Standard ML implementation of
wenzelm@57452
  1153
Poly/ML, without the add-ons of Isabelle/ML.  Commands 'SML_import'
wenzelm@57452
  1154
and 'SML_export' allow to exchange toplevel bindings between the two
wenzelm@57452
  1155
separate environments.  See also ~~/src/Tools/SML/Examples.thy for
wenzelm@57452
  1156
some examples.
wenzelm@56499
  1157
wenzelm@57504
  1158
* Standard tactics and proof methods such as "clarsimp", "auto" and
wenzelm@57504
  1159
"safe" now preserve equality hypotheses "x = expr" where x is a free
wenzelm@57504
  1160
variable.  Locale assumptions and chained facts containing "x"
wenzelm@57504
  1161
continue to be useful.  The new method "hypsubst_thin" and the
wenzelm@57504
  1162
configuration option "hypsubst_thin" (within the attribute name space)
wenzelm@57504
  1163
restore the previous behavior.  INCOMPATIBILITY, especially where
wenzelm@57504
  1164
induction is done after these methods or when the names of free and
wenzelm@57504
  1165
bound variables clash.  As first approximation, old proofs may be
wenzelm@57504
  1166
repaired by "using [[hypsubst_thin = true]]" in the critical spot.
wenzelm@57504
  1167
wenzelm@56232
  1168
* More static checking of proof methods, which allows the system to
wenzelm@56232
  1169
form a closure over the concrete syntax.  Method arguments should be
wenzelm@56232
  1170
processed in the original proof context as far as possible, before
wenzelm@56232
  1171
operating on the goal state.  In any case, the standard discipline for
wenzelm@56232
  1172
subgoal-addressing needs to be observed: no subgoals or a subgoal
wenzelm@56232
  1173
number that is out of range produces an empty result sequence, not an
wenzelm@56232
  1174
exception.  Potential INCOMPATIBILITY for non-conformant tactical
wenzelm@56232
  1175
proof tools.
wenzelm@56232
  1176
wenzelm@57452
  1177
* Lexical syntax (inner and outer) supports text cartouches with
wenzelm@57452
  1178
arbitrary nesting, and without escapes of quotes etc.  The Prover IDE
wenzelm@57452
  1179
supports input via ` (backquote).
wenzelm@57452
  1180
wenzelm@57452
  1181
* The outer syntax categories "text" (for formal comments and document
wenzelm@57452
  1182
markup commands) and "altstring" (for literal fact references) allow
wenzelm@57452
  1183
cartouches as well, in addition to the traditional mix of quotations.
wenzelm@57452
  1184
wenzelm@57452
  1185
* Syntax of document antiquotation @{rail} now uses \<newline> instead
wenzelm@57452
  1186
of "\\", to avoid the optical illusion of escaped backslash within
wenzelm@57491
  1187
string token.  General renovation of its syntax using text cartouches.
wenzelm@57452
  1188
Minor INCOMPATIBILITY.
wenzelm@57452
  1189
wenzelm@57452
  1190
* Discontinued legacy_isub_isup, which was a temporary workaround for
wenzelm@57452
  1191
Isabelle/ML in Isabelle2013-1.  The prover process no longer accepts
wenzelm@57452
  1192
old identifier syntax with \<^isub> or \<^isup>.  Potential
wenzelm@57452
  1193
INCOMPATIBILITY.
wenzelm@57452
  1194
wenzelm@57452
  1195
* Document antiquotation @{url} produces markup for the given URL,
wenzelm@57452
  1196
which results in an active hyperlink within the text.
wenzelm@57452
  1197
wenzelm@57452
  1198
* Document antiquotation @{file_unchecked} is like @{file}, but does
wenzelm@57452
  1199
not check existence within the file-system.
wenzelm@57452
  1200
wenzelm@57452
  1201
* Updated and extended manuals: codegen, datatypes, implementation,
wenzelm@57452
  1202
isar-ref, jedit, system.

  1205
*** Prover IDE -- Isabelle/Scala/jEdit ***
wenzelm@54533
  1206
wenzelm@57650
  1207
* Improved Document panel: simplified interaction where every single
wenzelm@57452
  1208
mouse click (re)opens document via desktop environment or as jEdit
wenzelm@57452
  1209
buffer.
wenzelm@57452
  1210
wenzelm@57452
  1211
* Support for Navigator plugin (with toolbar buttons), with connection
wenzelm@57452
  1212
to PIDE hyperlinks.
wenzelm@57452
  1213
wenzelm@57452
  1214
* Auxiliary files ('ML_file' etc.) are managed by the Prover IDE.
wenzelm@57452
  1215
Open text buffers take precedence over copies within the file-system.
wenzelm@57452
  1216
wenzelm@57452
  1217
* Improved support for Isabelle/ML, with jEdit mode "isabelle-ml" for
wenzelm@57452
  1218
auxiliary ML files.
wenzelm@57423
  1219
wenzelm@57423
  1220
* Improved syntactic and semantic completion mechanism, with simple
wenzelm@57423
  1221
templates, completion language context, name-space completion,
wenzelm@57423
  1222
file-name completion, spell-checker completion.
wenzelm@57423
  1223
wenzelm@57423
  1224
* Refined GUI popup for completion: more robust key/mouse event
wenzelm@57423
  1225
handling and propagation to enclosing text area -- avoid loosing
wenzelm@57423
  1226
keystrokes with slow / remote graphics displays.
wenzelm@57423
  1227
wenzelm@57833
  1228
* Completion popup supports both ENTER and TAB (default) to select an
wenzelm@57833
  1229
item, depending on Isabelle options.
wenzelm@57833
  1230
wenzelm@57423
  1231
* Refined insertion of completion items wrt. jEdit text: multiple
wenzelm@57423
  1232
selections, rectangular selections, rectangular selection as "tall
wenzelm@57423
  1233
caret".
wenzelm@56342
  1234
wenzelm@56580
  1235
* Integrated spell-checker for document text, comments etc. with
wenzelm@57423
  1236
completion popup and context-menu.
wenzelm@56554
  1237
wenzelm@56879
  1238
* More general "Query" panel supersedes "Find" panel, with GUI access
wenzelm@56879
  1239
to commands 'find_theorems' and 'find_consts', as well as print
wenzelm@56879
  1240
operations for the context.  Minor incompatibility in keyboard
wenzelm@56879
  1241
shortcuts etc.: replace action isabelle-find by isabelle-query.
wenzelm@56761
  1242
wenzelm@56901
  1243
* Search field for all output panels ("Output", "Query", "Info" etc.)
wenzelm@56901
  1244
to highlight text via regular expression.
wenzelm@56901
  1245
wenzelm@54881
  1246
* Option "jedit_print_mode" (see also "Plugin Options / Isabelle /
wenzelm@54881
  1247
General") allows to specify additional print modes for the prover
wenzelm@54881
  1248
process, without requiring old-fashioned command-line invocation of
wenzelm@54881
  1249
"isabelle jedit -m MODE".
wenzelm@54881
  1250
wenzelm@56505
  1251
* More support for remote files (e.g. http) using standard Java
wenzelm@56505
  1252
networking operations instead of jEdit virtual file-systems.
wenzelm@56505
  1253
wenzelm@57822
  1254
* Empty editors buffers that are no longer required (e.g.\ via theory
wenzelm@57822
  1255
imports) are automatically removed from the document model.
wenzelm@57822
  1256
wenzelm@57869
  1257
* Improved monitor panel.
wenzelm@57869
  1258
wenzelm@56838
  1259
* Improved Console/Scala plugin: more uniform scala.Console output,
wenzelm@56838
  1260
more robust treatment of threads and interrupts.
wenzelm@56838
  1261
wenzelm@56939
  1262
* Improved management of dockable windows: clarified keyboard focus
wenzelm@56939
  1263
and window placement wrt. main editor view; optional menu item to
wenzelm@56939
  1264
"Detach" a copy where this makes sense.
wenzelm@56939
  1265
wenzelm@57452
  1266
* New Simplifier Trace panel provides an interactive view of the
wenzelm@57591
  1267
simplification process, enabled by the "simp_trace_new" attribute
wenzelm@57452
  1268
within the context.

*** Pure ***
wenzelm@55001
  1272
wenzelm@57504
  1273
* Low-level type-class commands 'classes', 'classrel', 'arities' have
wenzelm@57504
  1274
been discontinued to avoid the danger of non-trivial axiomatization
wenzelm@57504
  1275
that is not immediately visible.  INCOMPATIBILITY, use regular
wenzelm@57504
  1276
'instance' command with proof.  The required OFCLASS(...) theorem
wenzelm@57504
  1277
might be postulated via 'axiomatization' beforehand, or the proof
wenzelm@57504
  1278
finished trivially if the underlying class definition is made vacuous
wenzelm@57504
  1279
(without any assumptions).  See also Isabelle/ML operations
wenzelm@57504
  1280
Axclass.class_axiomatization, Axclass.classrel_axiomatization,
wenzelm@57504
  1281
Axclass.arity_axiomatization.
wenzelm@57504
  1282
wenzelm@56245
  1283
* Basic constants of Pure use more conventional names and are always
wenzelm@56245
  1284
qualified.  Rare INCOMPATIBILITY, but with potentially serious
wenzelm@56245
  1285
consequences, notably for tools in Isabelle/ML.  The following
wenzelm@56245
  1286
renaming needs to be applied:
wenzelm@56245
  1287
wenzelm@56245
  1288
  ==             ~>  Pure.eq
wenzelm@56245
  1289
  ==>            ~>  Pure.imp
wenzelm@56245
  1290
  all            ~>  Pure.all
wenzelm@56245
  1291
  TYPE           ~>  Pure.type
wenzelm@56245
  1292
  dummy_pattern  ~>  Pure.dummy_pattern
wenzelm@56245
  1293
wenzelm@56245
  1294
Systematic porting works by using the following theory setup on a
wenzelm@56245
  1295
*previous* Isabelle version to introduce the new name accesses for the
wenzelm@56245
  1296
old constants:
wenzelm@56245
  1297
wenzelm@56245
  1298
setup {*
wenzelm@56245
  1299
  fn thy => thy
wenzelm@56245
  1300
    |> Sign.root_path
wenzelm@56245
  1301
    |> Sign.const_alias (Binding.qualify true "Pure" @{binding eq}) "=="
wenzelm@56245
  1302
    |> Sign.const_alias (Binding.qualify true "Pure" @{binding imp}) "==>"
wenzelm@56245
  1303
    |> Sign.const_alias (Binding.qualify true "Pure" @{binding all}) "all"
wenzelm@56245
  1304
    |> Sign.restore_naming thy
wenzelm@56245
  1305
*}
wenzelm@56245
  1306
wenzelm@56245
  1307
Thus ML antiquotations like @{const_name Pure.eq} may be used already.
wenzelm@56245
  1308
Later the application is moved to the current Isabelle version, and
wenzelm@56245
  1309
the auxiliary aliases are deleted.
wenzelm@56245
  1310
wenzelm@55143
  1311
* Attributes "where" and "of" allow an optional context of local
wenzelm@55143
  1312
variables ('for' declaration): these variables become schematic in the
wenzelm@55143
  1313
instantiated theorem.
wenzelm@55143
  1314
wenzelm@55152
  1315
* Obsolete attribute "standard" has been discontinued (legacy since
wenzelm@55152
  1316
Isabelle2012).  Potential INCOMPATIBILITY, use explicit 'for' context
wenzelm@55152
  1317
where instantiations with schematic variables are intended (for
wenzelm@55152
  1318
declaration commands like 'lemmas' or attributes like "of").  The
wenzelm@55152
  1319
following temporary definition may help to port old applications:
wenzelm@55152
  1320
wenzelm@55152
  1321
  attribute_setup standard =
wenzelm@55152
  1322
    "Scan.succeed (Thm.rule_attribute (K Drule.export_without_context))"
wenzelm@55152
  1323
wenzelm@55001
  1324
* More thorough check of proof context for goal statements and
wenzelm@55006
  1325
attributed fact expressions (concerning background theory, declared
wenzelm@55006
  1326
hyps).  Potential INCOMPATIBILITY, tools need to observe standard
wenzelm@55006
  1327
context discipline.  See also Assumption.add_assumes and the more
wenzelm@55006
  1328
primitive Thm.assume_hyps.
wenzelm@55001
  1329
wenzelm@55108
  1330
* Inner syntax token language allows regular quoted strings "..."
wenzelm@55108
  1331
(only makes sense in practice, if outer syntax is delimited
wenzelm@57452
  1332
differently, e.g. via cartouches).
wenzelm@57452
  1333
wenzelm@57504
  1334
* Command 'print_term_bindings' supersedes 'print_binds' for clarity,
wenzelm@57504
  1335
but the latter is retained some time as Proof General legacy.
wenzelm@57504
  1336
wenzelm@57452
  1337
* Code generator preprocessor: explicit control of simp tracing on a

wenzelm@57452
  1374
* Simplifier: Enhanced solver of preconditions of rewrite rules can
wenzelm@57452
  1375
now deal with conjunctions.  For help with converting proofs, the old
wenzelm@57452
  1376
behaviour of the simplifier can be restored like this: declare/using

    "sum.case").  INCOMPATIBILITY.
wenzelm@57452
  1455
  - The generated constants "xxx_case", "xxx_rec", and "xxx_size" have

wenzelm@57508
  1532
* New internal SAT solver "cdclite" that produces models and proof
wenzelm@57508
  1533
traces.  This solver replaces the internal SAT solvers "enumerate" and
wenzelm@57508
  1534
"dpll".  Applications that explicitly used one of these two SAT
wenzelm@57508
  1535
solvers should use "cdclite" instead. In addition, "cdclite" is now
wenzelm@57508
  1536
the default SAT solver for the "sat" and "satx" proof methods and
wenzelm@57508
  1537
corresponding tactics; the old default can be restored using "declare
wenzelm@57508

[[sat_solver = zchaff_with_proofs]]".  Minor INCOMPATIBILITY.
wenzelm@57508
  1539
wenzelm@57508
  1540
* SMT module: A new version of the SMT module, temporarily called
wenzelm@57508
  1541
"SMT2", uses SMT-LIB 2 and supports recent versions of Z3 (e.g.,
wenzelm@57508
  1542
4.3). The new proof method is called "smt2". CVC3 and CVC4 are also
wenzelm@57508
  1543
supported as oracles. Yices is no longer supported, because no version
wenzelm@57508
  1544
of the solver can handle both SMT-LIB 2 and quantifiers.
wenzelm@57508
  1545
wenzelm@57508
  1546
* Activation of Z3 now works via "z3_non_commercial" system option
wenzelm@57508
  1547
(without requiring restart), instead of former settings variable
wenzelm@57508
  1548
"Z3_NON_COMMERCIAL".  The option can be edited in Isabelle/jEdit menu

* Sledgehammer:
wenzelm@57508
  1552
  - Z3 can now produce Isar proofs.
wenzelm@57508
  1553
  - MaSh overhaul:
blanchet@57532
  1554
    . New SML-based learning algorithms eliminate the dependency on
wenzelm@57508
  1555
      Python and increase performance and reliability.
wenzelm@57508
  1556
    . MaSh and MeSh are now used by default together with the
wenzelm@57508
  1557
      traditional MePo (Meng-Paulson) relevance filter. To disable
wenzelm@57508
  1558
      MaSh, set the "MaSh" system option in Isabelle/jEdit Plugin
wenzelm@57508
  1559
      Options / Isabelle / General to "none".
wenzelm@57508
  1560
  - New option:
wenzelm@57508
  1561
      smt_proofs
wenzelm@57508
  1562
  - Renamed options:

INCOMPATIBILITY.
wenzelm@57508
  1567
wenzelm@57508

* Removed solvers remote_cvc3 and remote_z3. Use cvc3 and z3 instead.
wenzelm@57508
  1569
wenzelm@57508
  1570
* Nitpick:
wenzelm@57508
  1571
  - Fixed soundness bug whereby mutually recursive datatypes could
wenzelm@57508
  1572
    take infinite values.
wenzelm@57508
  1573
  - Fixed soundness bug with low-level number functions such as
wenzelm@57508
  1574
    "Abs_Integ" and "Rep_Integ".
wenzelm@57508
  1575
  - Removed "std" option.
wenzelm@57508
  1576
  - Renamed "show_datatypes" to "show_types" and "hide_datatypes" to
wenzelm@57508
  1577
    "hide_types".
wenzelm@57508
  1578
wenzelm@57508
  1579
* Metis: Removed legacy proof method 'metisFT'. Use 'metis
wenzelm@57508
  1580
(full_types)' instead. INCOMPATIBILITY.
wenzelm@57508
  1581
wenzelm@57508
  1582
* Try0: Added 'algebra' and 'meson' to the set of proof methods.
wenzelm@57508
  1583
wenzelm@57508
  1584
* Adjustion of INF and SUP operations:
wenzelm@57508
  1585
  - Elongated constants INFI and SUPR to INFIMUM and SUPREMUM.
wenzelm@57508
  1586
  - Consolidated theorem names containing INFI and SUPR: have INF and
wenzelm@57508
  1587
    SUP instead uniformly.
wenzelm@57508
  1588
  - More aggressive normalization of expressions involving INF and Inf
wenzelm@57508
  1589
    or SUP and Sup.
wenzelm@57508
  1590
  - INF_image and SUP_image do not unfold composition.
wenzelm@57508
  1591
  - Dropped facts INF_comp, SUP_comp.
wenzelm@57508
  1592
  - Default congruence rules strong_INF_cong and strong_SUP_cong, with
wenzelm@57508
  1593
    simplifier implication in premises.  Generalize and replace former
wenzelm@57508
  1594
    INT_cong, SUP_cong
wenzelm@57508

wenzelm@57508
  1596
INCOMPATIBILITY.
wenzelm@57508
  1597
wenzelm@57508

* SUP and INF generalized to conditionally_complete_lattice.
wenzelm@57508
  1599
wenzelm@57508
  1600
* Swapped orientation of facts image_comp and vimage_comp:

* The signature and semantics of Document.Snapshot.cumulate_markup /
wenzelm@55622
  2126
select_markup have been clarified.  Markup is now traversed in the
wenzelm@55622
  2127
order of reports given by the prover: later markup is usually more
wenzelm@55622
  2128
specific and may override results accumulated so far.  The elements
wenzelm@55622
  2129
guard is mandatory and checked precisely.  Subtle INCOMPATIBILITY.
wenzelm@55622

*** ML ***
wenzelm@54449
  2136
wenzelm@57504
  2137
* Subtle change of semantics of Thm.eq_thm: theory stamps are not
wenzelm@57504
  2138
compared (according to Thm.thm_ord), but assumed to be covered by the
wenzelm@57504
  2139
current background theory.  Thus equivalent data produced in different
wenzelm@57504
  2140
branches of the theory graph usually coincides (e.g. relevant for
wenzelm@57504
  2141
theory merge).  Note that the softer Thm.eq_thm_prop is often more
wenzelm@57504
  2142
appropriate than Thm.eq_thm.
wenzelm@57504
  2143
wenzelm@57504
  2144
* Proper context for basic Simplifier operations: rewrite_rule,
wenzelm@57504
  2145
rewrite_goals_rule, rewrite_goals_tac etc. INCOMPATIBILITY, need to
wenzelm@57504
  2146
pass runtime Proof.context (and ensure that the simplified entity
wenzelm@57504
  2147
actually belongs to it).
wenzelm@57504
  2148
wenzelm@57504
  2149
* Proper context discipline for read_instantiate and instantiate_tac:
wenzelm@57504
  2150
variables that are meant to become schematic need to be given as
wenzelm@57504
  2151
fixed, and are generalized by the explicit context of local variables.
wenzelm@57504
  2152
This corresponds to Isar attributes "where" and "of" with 'for'
wenzelm@57504
  2153
declaration.  INCOMPATIBILITY, also due to potential change of indices
wenzelm@57504
  2154
of schematic variables.
wenzelm@57504
  2155
wenzelm@56303
  2156
* Moved ML_Compiler.exn_trace and other operations on exceptions to

  2157
structure Runtime.  Minor INCOMPATIBILITY.
wenzelm@56303
  2158
wenzelm@56279
  2159
* Discontinued old Toplevel.debug in favour of system option
wenzelm@57452
  2160
"ML_exception_trace", which may be also declared within the context
wenzelm@57452
  2161
via "declare [[ML_exception_trace = true]]".  Minor INCOMPATIBILITY.
wenzelm@56279
  2162
wenzelm@56281
  2163
* Renamed configuration option "ML_trace" to "ML_source_trace". Minor
wenzelm@56281
  2164
INCOMPATIBILITY.
wenzelm@56281
  2165
wenzelm@56281
  2166
* Configuration option "ML_print_depth" controls the pretty-printing
wenzelm@56281
  2167
depth of the ML compiler within the context.  The old print_depth in
wenzelm@56285
  2168
ML is still available as default_print_depth, but rarely used.  Minor
wenzelm@56285
  2169
INCOMPATIBILITY.
wenzelm@56279
  2170
wenzelm@54449
  2171
* Toplevel function "use" refers to raw ML bootstrap environment,
wenzelm@54449
  2172
without Isar context nor antiquotations.  Potential INCOMPATIBILITY.
wenzelm@54449
  2173
Note that 'ML_file' is the canonical command to load ML files into the
wenzelm@54449
  2174
formal context.
wenzelm@54449
  2175
wenzelm@56205
  2176
* Simplified programming interface to define ML antiquotations, see
wenzelm@56205
  2177
structure ML_Antiquotation.  Minor INCOMPATIBILITY.
wenzelm@56069
  2178
wenzelm@56071
  2179
* ML antiquotation @{here} refers to its source position, which is
wenzelm@56071
  2180
occasionally useful for experimentation and diagnostic purposes.
wenzelm@56071
  2181
wenzelm@56135
  2182
* ML antiquotation @{path} produces a Path.T value, similarly to
wenzelm@56135
  2183
Path.explode, but with compile-time check against the file-system and
wenzelm@56135
  2184
some PIDE markup.  Note that unlike theory source, ML does not have a
wenzelm@56135
  2185
well-defined master directory, so an absolute symbolic path
wenzelm@56135
  2186
specification is usually required, e.g. "~~/src/HOL".
wenzelm@56135
  2187
wenzelm@56399
  2188
* ML antiquotation @{print} inlines a function to print an arbitrary
wenzelm@56399
  2189
ML value, which is occasionally useful for diagnostic or demonstration
wenzelm@56399
  2190
purposes.

* Proof General with its traditional helper scripts is now an optional
wenzelm@57504
  2196
Isabelle component, e.g. see ProofGeneral-4.2-2 from the Isabelle
wenzelm@57504
  2197
component repository http://isabelle.in.tum.de/components/.  Note that
wenzelm@57504
  2198
the "system" manual provides general explanations about add-on
wenzelm@57504
  2199
components, especially those that are not bundled with the release.
wenzelm@57443
  2200
wenzelm@56439
  2201
* The raw Isabelle process executable has been renamed from
wenzelm@56439
  2202
"isabelle-process" to "isabelle_process", which conforms to common
wenzelm@56439
  2203
shell naming conventions, and allows to define a shell function within
wenzelm@56439
  2204
the Isabelle environment to avoid dynamic path lookup.  Rare
wenzelm@57504
  2205
incompatibility for old tools that do not use the ISABELLE_PROCESS
wenzelm@57504
  2206
settings variable.
wenzelm@56439
  2207
wenzelm@57439
  2208
* Former "isabelle tty" has been superseded by "isabelle console",
wenzelm@57439
  2209
with implicit build like "isabelle jedit", and without the mostly
wenzelm@57439
  2210
obsolete Isar TTY loop.
wenzelm@57439
  2211
wenzelm@57452
  2212
* Simplified "isabelle display" tool.  Settings variables DVI_VIEWER
wenzelm@57452
  2213
and PDF_VIEWER now refer to the actual programs, not shell
wenzelm@57452
  2214
command-lines.  Discontinued option -c: invocation may be asynchronous
wenzelm@57452
  2215
via desktop environment, without any special precautions.  Potential
wenzelm@57452
  2216
INCOMPATIBILITY with ambitious private settings.
wenzelm@57452
  2217
wenzelm@57413
  2218
* Removed obsolete "isabelle unsymbolize".  Note that the usual format
wenzelm@57413
  2219
for email communication is the Unicode rendering of Isabelle symbols,
wenzelm@57413
  2220
as produced by Isabelle/jEdit, for example.
wenzelm@57413
  2221
wenzelm@57452
  2222
* Removed obsolete tool "wwwfind". Similar functionality may be
wenzelm@57452
  2223
integrated into Isabelle/jEdit eventually.
wenzelm@57452
  2224
wenzelm@57452
  2225
* Improved 'display_drafts' concerning desktop integration and
wenzelm@57452
  2226
repeated invocation in PIDE front-end: re-use single file
wenzelm@57452
  2227
$ISABELLE_HOME_USER/tmp/drafts.pdf and corresponding views.
wenzelm@57084
  2228
wenzelm@57452
  2229
* Session ROOT specifications require explicit 'document_files' for
wenzelm@57452
  2230
robust dependencies on LaTeX sources.  Only these explicitly given
wenzelm@57452
  2231
files are copied to the document output directory, before document
wenzelm@57452
  2232
processing is started.
wenzelm@57452
  2233
wenzelm@57504
  2234
* Windows: support for regular TeX installation (e.g. MiKTeX) instead
wenzelm@57504
  2235
of TeX Live from Cygwin.

e.g. non-terminating 'by' steps.
wenzelm@54639
  2246
wenzelm@54641

wenzelm@54641
  2249
wenzelm@54648

*** General ***
wenzelm@51293
  2272
wenzelm@53971
  2273
* Discontinued obsolete 'uses' within theory header.  Note that
wenzelm@53971
  2274
commands like 'ML_file' work without separate declaration of file
wenzelm@53971
  2275

'ML_file' in Isabelle2013.  Minor INCOMPATIBILITY.
wenzelm@53971
  2279
wenzelm@53016
  2280
* Simplified subscripts within identifiers, using plain \<^sub>
wenzelm@53016
  2281
instead of the second copy \<^isub> and \<^isup>.  Superscripts are
wenzelm@53016
  2282
only for literal tokens within notation; explicit mixfix annotations
wenzelm@53016
  2283
for consts or fixed variables may be used as fall-back for unusual
wenzelm@53016
  2284
names.  Obsolete \<twosuperior> has been expanded to \<^sup>2 in
wenzelm@53016
  2285
Isabelle/HOL.  INCOMPATIBILITY, use "isabelle update_sub_sup" to
wenzelm@53016
  2286
standardize symbols as a starting point for further manual cleanup.
wenzelm@53016
  2287
The ML reference variable "legacy_isub_isup" may be set as temporary
wenzelm@53016
  2288
workaround, to make the prover accept a subset of the old identifier
wenzelm@53016
  2289
syntax.
wenzelm@53016
  2290
wenzelm@53021
  2291
* Document antiquotations: term style "isub" has been renamed to

  2292
"sub".  Minor INCOMPATIBILITY.
wenzelm@53021
  2293
wenzelm@52487
  2294
* Uniform management of "quick_and_dirty" as system option (see also
wenzelm@52487
  2295
"isabelle options"), configuration option within the context (see also
wenzelm@52487
  2296
Config.get in Isabelle/ML), and attribute in Isabelle/Isar.  Minor
wenzelm@52487
  2297
INCOMPATIBILITY, need to use more official Isabelle means to access
wenzelm@52487
  2298
quick_and_dirty, instead of historical poking into mutable reference.
wenzelm@52059
  2299
wenzelm@52060
  2300
* Renamed command 'print_configs' to 'print_options'.  Minor

  2301
INCOMPATIBILITY.
wenzelm@52060
  2302
wenzelm@52430
  2303
* Proper diagnostic command 'print_state'.  Old 'pr' (with its
wenzelm@52430
  2304
implicit change of some global references) is retained for now as
wenzelm@52430
  2305
control command, e.g. for ProofGeneral 3.7.x.
wenzelm@52430
  2306
wenzelm@52549
  2307
* Discontinued 'print_drafts' command with its old-fashioned PS output
wenzelm@52549
  2308
and Unix command-line print spooling.  Minor INCOMPATIBILITY: use
wenzelm@52549
  2309
'display_drafts' instead and print via the regular document viewer.
wenzelm@52549
  2310
wenzelm@53971
  2311
* Updated and extended "isar-ref" and "implementation" manual,
wenzelm@53971

  2324
(GUI front-end to 'find_theorems' command).
wenzelm@52949
  2325
wenzelm@53050
  2326
* Dockable window "Sledgehammer" manages asynchronous / parallel

wenzelm@53050
  2328
normal editing and checking process.
wenzelm@53050
  2329
wenzelm@51533
  2330
* Dockable window "Timing" provides an overview of relevant command
wenzelm@54332
  2331
timing information, depending on option jedit_timing_threshold.  The
wenzelm@54332
  2332
same timing information is shown in the extended tooltip of the
wenzelm@54332
  2333
command keyword, when hovering the mouse over it while the CONTROL or

  2334
COMMAND modifier is pressed.
wenzelm@51533
  2335
wenzelm@53971
  2336
* Improved dockable window "Theories": Continuous checking of proof
wenzelm@53971
  2337
document (visible and required parts) may be controlled explicitly,
wenzelm@53971
  2338
using check box or shortcut "C+e ENTER".  Individual theory nodes may
wenzelm@53971
  2339
be marked explicitly as required and checked in full, using check box
wenzelm@53971
  2340
or shortcut "C+e SPACE".
wenzelm@53971
  2341
wenzelm@54305
  2342
* Improved completion mechanism, which is now managed by the
wenzelm@54305
  2343
Isabelle/jEdit plugin instead of SideKick.  Refined table of Isabelle
wenzelm@54305
  2344
symbol abbreviations (see $ISABELLE_HOME/etc/symbols).
wenzelm@54305
  2345
wenzelm@54319
  2346
* Standard jEdit keyboard shortcut C+b complete-word is remapped to
wenzelm@54319
  2347
isabelle.complete for explicit completion in Isabelle sources.
wenzelm@54319
  2348
INCOMPATIBILITY wrt. jEdit defaults, may have to invent new shortcuts
wenzelm@54319
  2349
to resolve conflict.
wenzelm@54319
  2350
wenzelm@54305
  2351
* Improved support of various "minor modes" for Isabelle NEWS,
wenzelm@54305
  2352
options, session ROOT etc., with completion and SideKick tree view.
wenzelm@54305
  2353
wenzelm@53971
  2354
* Strictly monotonic document update, without premature cancellation of
wenzelm@53971
  2355
running transactions that are still needed: avoid reset/restart of
wenzelm@53971
  2356
such command executions while editing.
wenzelm@53271
  2357
wenzelm@53971
  2358

wenzelm@53971
  2360
wenzelm@53971
  2361
* Support for automatic tools in HOL, which try to prove or disprove
wenzelm@53971
  2362
toplevel theorem statements.
wenzelm@53971
  2363
wenzelm@53971
  2364
* Action isabelle.reset-font-size resets main text area font size
wenzelm@54365
  2365
according to Isabelle/Scala plugin option "jedit_font_reset_size" (see
wenzelm@54365
  2366
also "Plugin Options / Isabelle / General").  It can be bound to some
wenzelm@54365
  2367
keyboard shortcut by the user (e.g. C+0 and/or C+NUMPAD0).
wenzelm@53971
  2368
wenzelm@53971
  2369
* File specifications in jEdit (e.g. file browser) may refer to
wenzelm@54351
  2370
$ISABELLE_HOME and $ISABELLE_HOME_USER on all platforms.  Discontinued
wenzelm@54351
  2371
obsolete $ISABELLE_HOME_WINDOWS variable.
wenzelm@53971
  2372
wenzelm@53971
  2373
* Improved support for Linux look-and-feel "GTK+", see also "Utilities

  2374
/ Global Options / Appearance".
wenzelm@53971
  2375
wenzelm@53971
  2376
* Improved support of native Mac OS X functionality via "MacOSX"

ballarin@54049
  2382
* Commands 'interpretation' and 'sublocale' are now target-sensitive.
ballarin@54049
  2383
In particular, 'interpretation' allows for non-persistent
ballarin@54049
  2384
interpretation within "context ... begin ... end" blocks offering a
ballarin@54049
  2385
light-weight alternative to 'sublocale'.  See "isar-ref" manual for
ballarin@54049
  2386
details.
haftmann@51747
  2387
ballarin@51565
  2388
* Improved locales diagnostic command 'print_dependencies'.
ballarin@51565
  2389
wenzelm@51313
  2390
* Discontinued obsolete 'axioms' command, which has been marked as
wenzelm@51313
  2391
legacy since Isabelle2009-2.  INCOMPATIBILITY, use 'axiomatization'
wenzelm@51313
  2392
instead, while observing its uniform scope for polymorphism.
wenzelm@51313
  2393
wenzelm@51316
  2394
* Discontinued empty name bindings in 'axiomatization'.
wenzelm@51316
  2395
INCOMPATIBILITY.
wenzelm@51316
  2396
wenzelm@53971
  2397
* System option "proofs" has been discontinued.  Instead the global
wenzelm@53971
  2398
state of Proofterm.proofs is persistently compiled into logic images
wenzelm@53971
  2399
as required, notably HOL-Proofs.  Users no longer need to change
wenzelm@53971
  2400
Proofterm.proofs dynamically.  Minor INCOMPATIBILITY.
wenzelm@53971
  2401
wenzelm@53971
  2402
* Syntax translation functions (print_translation etc.) always depend
wenzelm@53971
  2403
on Proof.context.  Discontinued former "(advanced)" option -- this is
wenzelm@53971
  2404
now the default.  Minor INCOMPATIBILITY.
wenzelm@53971
  2405
wenzelm@53971
  2406
* Former global reference trace_unify_fail is now available as

  2407
configuration option "unify_trace_failure" (global context only).
wenzelm@53971
  2408
wenzelm@52463
  2409
* SELECT_GOAL now retains the syntactic context of the overall goal
wenzelm@52463
  2410

wenzelm@52463
  2411
situations.

hoelzl@51002
  2415
wenzelm@54032
  2416
* Stronger precedence of syntax for big intersection and union on
wenzelm@54032
  2417
sets, in accordance with corresponding lattice operations.
wenzelm@54032
  2418
INCOMPATIBILITY.
wenzelm@54032
  2419
wenzelm@54032
  2420
* Notation "{p:A. P}" now allows tuple patterns as well.
wenzelm@54032
  2421
wenzelm@54032
  2422
* Nested case expressions are now translated in a separate check phase
wenzelm@54032
  2423
rather than during parsing. The data for case combinators is separated
wenzelm@54032
  2424
from the datatype package. The declaration attribute
wenzelm@54032
  2425
"case_translation" can be used to register new case combinators:
wenzelm@54032
  2426
wenzelm@54032
  2427
  declare [[case_translation case_combinator constructor1 ... constructorN]]
haftmann@52637
  2428
haftmann@52435
  2429
* Code generator:
wenzelm@53160
  2430
  - 'code_printing' unifies 'code_const' / 'code_type' / 'code_class' /
wenzelm@53160
  2431
    'code_instance'.
wenzelm@53160
  2432
  - 'code_identifier' declares name hints for arbitrary identifiers in
wenzelm@53160
  2433
    generated code, subsuming 'code_modulename'.
wenzelm@53983
  2434
wenzelm@53983

See the isar-ref manual for syntax diagrams, and the HOL theories for
wenzelm@53983
  2436
examples.
haftmann@52435
  2437
wenzelm@54032
  2438
* Attibute 'code': 'code' now declares concrete and abstract code
wenzelm@54032
  2439
equations uniformly.  Use explicit 'code equation' and 'code abstract'
wenzelm@54032
  2440
to distinguish both when desired.
wenzelm@54032
  2441
wenzelm@54032
  2442
* Discontinued theories Code_Integer and Efficient_Nat by a more
wenzelm@54032
  2443
fine-grain stack of theories Code_Target_Int, Code_Binary_Nat,
wenzelm@54032
  2444
Code_Target_Nat and Code_Target_Numeral.  See the tutorial on code

  2445
generation for details.  INCOMPATIBILITY.
wenzelm@54032
  2446
wenzelm@54032
  2447
* Numeric types are mapped by default to target language numerals:
wenzelm@54032
  2448
natural (replaces former code_numeral) and integer (replaces former
wenzelm@54032
  2449
code_int).  Conversions are available as integer_of_natural /
wenzelm@54032
  2450
natural_of_integer / integer_of_nat / nat_of_integer (in HOL) and
wenzelm@54032
  2451
Code_Numeral.integer_of_natural / Code_Numeral.natural_of_integer (in
wenzelm@54032
  2452
ML).  INCOMPATIBILITY.
wenzelm@54032
  2453
wenzelm@54032
  2454
* Function package: For mutually recursive functions f and g, separate
wenzelm@54032
  2455
cases rules f.cases and g.cases are generated instead of unusable
wenzelm@54032
  2456
f_g.cases which exposed internal sum types. Potential INCOMPATIBILITY,
wenzelm@54032
  2457
in the case that the unusable rule was used nevertheless.
wenzelm@54032
  2458
wenzelm@54032
  2459
* Function package: For each function f, new rules f.elims are
wenzelm@54032
  2460
generated, which eliminate equalities of the form "f x = t".
wenzelm@54032
  2461
wenzelm@54032
  2462
* New command 'fun_cases' derives ad-hoc elimination rules for
wenzelm@54032
  2463
function equations as simplified instances of f.elims, analogous to
wenzelm@54032
  2464
inductive_cases.  See ~~/src/HOL/ex/Fundefs.thy for some examples.
blanchet@53307
  2465
kuncar@54021
  2466
* Lifting:
kuncar@54021
  2467
  - parametrized correspondence relations are now supported:
wenzelm@54378
  2468
    + parametricity theorems for the raw term can be specified in
kuncar@54021
  2469
      the command lift_definition, which allow us to generate stronger
kuncar@54021
  2470
      transfer rules
kuncar@54021
  2471
    + setup_lifting generates stronger transfer rules if parametric
kuncar@54021
  2472
      correspondence relation can be generated
kuncar@54021
  2473
    + various new properties of the relator must be specified to support
kuncar@54021
  2474
      parametricity
kuncar@54021
  2475
    + parametricity theorem for the Quotient relation can be specified
kuncar@54021
  2476
  - setup_lifting generates domain rules for the Transfer package
kuncar@54021
  2477
  - stronger reflexivity prover of respectfulness theorems for type
kuncar@54021
  2478
    copies
kuncar@54021
  2479
  - ===> and --> are now local. The symbols can be introduced
kuncar@54021
  2480
    by interpreting the locale lifting_syntax (typically in an
kuncar@54021
  2481
    anonymous context)
wenzelm@54378
  2482
  - Lifting/Transfer relevant parts of Library/Quotient_* are now in
kuncar@54021
  2483
    Main. Potential INCOMPATIBILITY
kuncar@54021
  2484
  - new commands for restoring and deleting Lifting/Transfer context:
kuncar@54021
  2485
    lifting_forget, lifting_update
wenzelm@54378
  2486
  - the command print_quotmaps was renamed to print_quot_maps.
kuncar@54021
  2487
    INCOMPATIBILITY
kuncar@54021
  2488
kuncar@54021
  2489
* Transfer:
wenzelm@54378
  2490
  - better support for domains in Transfer: replace Domainp T
kuncar@54021
  2491
    by the actual invariant in a transferred goal
kuncar@54021
  2492
  - transfer rules can have as assumptions other transfer rules
kuncar@54021
  2493
  - Experimental support for transferring from the raw level to the
kuncar@54021
  2494
    abstract level: Transfer.transferred attribute
kuncar@54021
  2495
  - Attribute version of the transfer method: untransferred attribute
kuncar@54021
  2496
haftmann@52286
  2497
* Reification and reflection:
wenzelm@53160
  2498
  - Reification is now directly available in HOL-Main in structure
wenzelm@53160
  2499
    "Reification".
wenzelm@53160
  2500
  - Reflection now handles multiple lists with variables also.
wenzelm@53160
  2501
  - The whole reflection stack has been decomposed into conversions.
haftmann@52286
  2502
INCOMPATIBILITY.
haftmann@52286
  2503
haftmann@51489
  2504
* Revised devices for recursive definitions over finite sets:
haftmann@51489
  2505
  - Only one fundamental fold combinator on finite set remains:
haftmann@51489
  2506
    Finite_Set.fold :: ('a => 'b => 'b) => 'b => 'a set => 'b
haftmann@51489
  2507
    This is now identity on infinite sets.
wenzelm@52745
  2508
  - Locales ("mini packages") for fundamental definitions with
haftmann@51489
  2509
    Finite_Set.fold: folding, folding_idem.
haftmann@51489
  2510
  - Locales comm_monoid_set, semilattice_order_set and
haftmann@51489
  2511
    semilattice_neutr_order_set for big operators on sets.
haftmann@51489
  2512
    See theory Big_Operators for canonical examples.
haftmann@51489
  2513
    Note that foundational constants comm_monoid_set.F and
haftmann@51489
  2514
    semilattice_set.F correspond to former combinators fold_image
haftmann@51489
  2515
    and fold1 respectively.  These are now gone.  You may use
haftmann@51490
  2516
    those foundational constants as substitutes, but it is
wenzelm@53983
  2517
    preferable to interpret the above locales accordingly.
haftmann@51489
  2518
  - Dropped class ab_semigroup_idem_mult (special case of lattice,
haftmann@51489
  2519
    no longer needed in connection with Finite_Set.fold etc.)
haftmann@51489
  2520
  - Fact renames:
haftmann@51489
  2521
      card.union_inter ~> card_Un_Int [symmetric]
haftmann@51489
  2522
      card.union_disjoint ~> card_Un_disjoint
haftmann@51489
  2523
INCOMPATIBILITY.
haftmann@51489
  2524
haftmann@51487
  2525
* Locale hierarchy for abstract orderings and (semi)lattices.
haftmann@51487
  2526
wenzelm@53526
  2527
* Complete_Partial_Order.admissible is defined outside the type class
wenzelm@53526
  2528
ccpo, but with mandatory prefix ccpo. Admissibility theorems lose the
wenzelm@53526
  2529
class predicate assumption or sort constraint when possible.
Andreas@53362
  2530
INCOMPATIBILITY.
Andreas@53362
  2531
wenzelm@53160
  2532
* Introduce type class "conditionally_complete_lattice": Like a
wenzelm@53160
  2533
complete lattice but does not assume the existence of the top and
wenzelm@53160
  2534
bottom elements.  Allows to generalize some lemmas about reals and
wenzelm@53160
  2535
extended reals.  Removed SupInf and replaced it by the instantiation
wenzelm@53160
  2536
of conditionally_complete_lattice for real. Renamed lemmas about
wenzelm@53160
  2537
conditionally-complete lattice from Sup_... to cSup_... and from
wenzelm@53160
  2538
Inf_...  to cInf_... to avoid hidding of similar complete lattice
wenzelm@53160
  2539
lemmas.
wenzelm@53160
  2540
wenzelm@53160
  2541
* Introduce type class linear_continuum as combination of
wenzelm@53160
  2542
conditionally-complete lattices and inner dense linorders which have
wenzelm@53160
  2543
more than one element.  INCOMPATIBILITY.
wenzelm@53160
  2544
wenzelm@53983
  2545
* Introduced type classes order_top and order_bot. The old classes top
wenzelm@53983
  2546
and bot only contain the syntax without assumptions.  INCOMPATIBILITY:
wenzelm@53983
  2547
Rename bot -> order_bot, top -> order_top
lammich@53683
  2548
wenzelm@53160
  2549
* Introduce type classes "no_top" and "no_bot" for orderings without
wenzelm@53160
  2550
top and bottom elements.
hoelzl@51732
  2551
hoelzl@51732
  2552
* Split dense_linorder into inner_dense_order and no_top, no_bot.
hoelzl@51732
  2553
hoelzl@51732
  2554
* Complex_Main: Unify and move various concepts from
wenzelm@53160
  2555
HOL-Multivariate_Analysis to HOL-Complex_Main.
hoelzl@51732
  2556
wenzelm@53983
  2557
 - Introduce type class (lin)order_topology and
wenzelm@53983
  2558
   linear_continuum_topology.  Allows to generalize theorems about
wenzelm@53983
  2559
   limits and order.  Instances are reals and extended reals.
hoelzl@51732
  2560
hoelzl@51732
  2561
 - continuous and continuos_on from Multivariate_Analysis:
wenzelm@53983
  2562
   "continuous" is the continuity of a function at a filter.  "isCont"
wenzelm@53983
  2563
   is now an abbrevitation: "isCont x f == continuous (at _) f".
wenzelm@53983
  2564
wenzelm@53983
  2565
   Generalized continuity lemmas from isCont to continuous on an
wenzelm@53983
  2566
   arbitrary filter.
wenzelm@53983
  2567
wenzelm@53983
  2568
 - compact from Multivariate_Analysis. Use Bolzano's lemma to prove
wenzelm@53983
  2569
   compactness of closed intervals on reals. Continuous functions
wenzelm@53983
  2570
   attain infimum and supremum on compact sets. The inverse of a
wenzelm@53983
  2571
   continuous function is continuous, when the function is continuous
wenzelm@53983
  2572
   on a compact set.
hoelzl@51732
  2573
hoelzl@51732
  2574
 - connected from Multivariate_Analysis. Use it to prove the
hoelzl@51775
  2575
   intermediate value theorem. Show connectedness of intervals on
hoelzl@51775
  2576
   linear_continuum_topology).
hoelzl@51732
  2577
hoelzl@51732
  2578
 - first_countable_topology from Multivariate_Analysis. Is used to
wenzelm@53983
  2579
   show equivalence of properties on the neighbourhood filter of x and
wenzelm@53983
  2580
   on all sequences converging to x.
wenzelm@53983
  2581
wenzelm@53983
  2582
 - FDERIV: Definition of has_derivative moved to Deriv.thy. Moved
wenzelm@53983
  2583
   theorems from Library/FDERIV.thy to Deriv.thy and base the
wenzelm@53983
  2584
   definition of DERIV on FDERIV. Add variants of DERIV and FDERIV
wenzelm@53983
  2585
   which are restricted to sets, i.e. to represent derivatives from
wenzelm@53983
  2586
   left or right.
hoelzl@51732
  2587
hoelzl@51732
  2588
 - Removed the within-filter. It is replaced by the principal filter:
hoelzl@51732
  2589
hoelzl@51732
  2590
     F within X = inf F (principal X)
hoelzl@51732
  2591
hoelzl@51732
  2592
 - Introduce "at x within U" as a single constant, "at x" is now an
hoelzl@51732
  2593
   abbreviation for "at x within UNIV"
hoelzl@51732
  2594
wenzelm@53983
  2595
 - Introduce named theorem collections tendsto_intros,
wenzelm@53983
  2596
   continuous_intros, continuous_on_intros and FDERIV_intros. Theorems
wenzelm@53983
  2597
   in tendsto_intros (or FDERIV_intros) are also available as
wenzelm@53983
  2598
   tendsto_eq_intros (or FDERIV_eq_intros) where the right-hand side
wenzelm@53983
  2599
   is replaced by a congruence rule. This allows to apply them as
wenzelm@53983
  2600
   intro rules and then proving equivalence by the simplifier.
hoelzl@51732
  2601
hoelzl@51732
  2602
 - Restructured theories in HOL-Complex_Main:
hoelzl@51732
  2603
hoelzl@51732
  2604
   + Moved RealDef and RComplete into Real
hoelzl@51732
  2605
hoelzl@51732
  2606
   + Introduced Topological_Spaces and moved theorems about
hoelzl@51732
  2607
     topological spaces, filters, limits and continuity to it
hoelzl@51732
  2608
hoelzl@51732
  2609
   + Renamed RealVector to Real_Vector_Spaces
hoelzl@51732
  2610
wenzelm@53983
  2611
   + Split Lim, SEQ, Series into Topological_Spaces,
wenzelm@53983
  2612
     Real_Vector_Spaces, and Limits
hoelzl@51732
  2613
hoelzl@51732
  2614
   + Moved Ln and Log to Transcendental
hoelzl@51732
  2615
hoelzl@51732
  2616
   + Moved theorems about continuity from Deriv to Topological_Spaces
hoelzl@51732
  2617
hoelzl@51732
  2618
 - Remove various auxiliary lemmas.

* Nitpick:
blanchet@55889
  2623
  - Added option "spy".

* Library/Polynomial.thy:
wenzelm@54032
  2638
  - Use lifting for primitive definitions.
wenzelm@54032
  2639
  - Explicit conversions from and to lists of coefficients, used for
wenzelm@54032
  2640
    generated code.
wenzelm@54032
  2641
  - Replaced recursion operator poly_rec by fold_coeffs.
wenzelm@54032
  2642
  - Prefer pre-existing gcd operation for gcd.
wenzelm@54032
  2643
  - Fact renames:
wenzelm@54032
  2644
    poly_eq_iff ~> poly_eq_poly_eq_iff
wenzelm@54032
  2645
    poly_ext ~> poly_eqI
wenzelm@54032

* New Library/Simps_Case_Conv.thy: Provides commands simps_of_case and
wenzelm@54032
  2650
case_of_simps to convert function definitions between a list of
wenzelm@54032
  2651
equations with patterns on the lhs and a single equation with case
wenzelm@54032
  2652
expressions on the rhs. See also Ex/Simps_Case_Conv_Examples.thy.
wenzelm@54032
  2653
wenzelm@54032

* New Library/FSet.thy: type of finite sets defined as a subtype of
wenzelm@54032
  2655
sets defined by Lifting/Transfer.
wenzelm@54032
  2656

wenzelm@54032
  2658
wenzelm@54032

* Consolidation of library theories on product orders:
wenzelm@54032
  2660
wenzelm@54032
  2661
    Product_Lattice ~> Product_Order -- pointwise order on products
wenzelm@54032
  2662
    Product_ord ~> Product_Lexorder -- lexicographic order on products
wenzelm@54032

* Imperative-HOL: The MREC combinator is considered legacy and no
wenzelm@53160
  2667
longer included by default. INCOMPATIBILITY, use partial_function
wenzelm@53160
  2668
instead, or import theory Legacy_Mrec as a fallback.
wenzelm@53160
  2669
wenzelm@53983
  2670
* HOL-Algebra: Discontinued theories ~~/src/HOL/Algebra/abstract and
wenzelm@53983
  2671
~~/src/HOL/Algebra/poly.  Existing theories should be based on
wenzelm@53983
  2672
~~/src/HOL/Library/Polynomial instead.  The latter provides
wenzelm@53983
  2673
integration with HOL's type classes for rings.  INCOMPATIBILITY.

* HOL-BNF:
wenzelm@54032
  2676
  - Various improvements to BNF-based (co)datatype package, including
wenzelm@54032
  2677
    new commands "primrec_new", "primcorec", and
wenzelm@54032
  2678
    "datatype_new_compat", as well as documentation. See
wenzelm@54032
  2679
    "datatypes.pdf" for details.
wenzelm@54032
  2680
  - New "coinduction" method to avoid some boilerplate (compared to
wenzelm@54032
  2681
    coinduct).
wenzelm@54032
  2682
  - Renamed keywords:
wenzelm@54032
  2683
    data ~> datatype_new
wenzelm@54032
  2684
    codata ~> codatatype
wenzelm@54032
  2685
    bnf_def ~> bnf
wenzelm@54032
  2686
  - Renamed many generated theorems, including
wenzelm@54032
  2687
    discs ~> disc
wenzelm@54032
  2688
    map_comp' ~> map_comp

  2698
* Spec_Check is a Quickcheck tool for Isabelle/ML.  The ML function
wenzelm@53971
  2699
"check_property" allows to check specifications of the form "ALL x y
wenzelm@53971
  2700
z. prop x y z".  See also ~~/src/Tools/Spec_Check/ with its
wenzelm@53971
  2701
Examples.thy in particular.
wenzelm@53971
  2702
wenzelm@53709
  2703
* Improved printing of exception trace in Poly/ML 5.5.1, with regular
wenzelm@53709
  2704
tracing output in the command transaction context instead of physical
wenzelm@53709
  2705
stdout.  See also Toplevel.debug, Toplevel.debugging and

wenzelm@53971
  2708
* ML type "theory" is now immutable, without any special treatment of
wenzelm@53971
  2709
drafts or linear updates (which could lead to "stale theory" errors in
wenzelm@53971
  2710
the past).  Discontinued obsolete operations like Theory.copy,
wenzelm@53971
  2711
Theory.checkpoint, and the auxiliary type theory_ref.  Minor

  2712
INCOMPATIBILITY.
wenzelm@53164
  2713
wenzelm@51551
  2714
* More uniform naming of goal functions for skipped proofs:
wenzelm@51551
  2715
wenzelm@51551
  2716
    Skip_Proof.prove  ~>  Goal.prove_sorry
wenzelm@51551
