*** 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
    28
wenzelm@61958
    29
* Former "xsymbols" syntax with Isabelle symbols is used by default,
wenzelm@61958
    30
without any special print mode. Important ASCII replacement syntax
wenzelm@61958
    31
remains available under print mode "ASCII", but less important syntax
wenzelm@61958
    32
has been removed (see below).
wenzelm@61958
    33
wenzelm@61964
    34
* Support for more arrow symbols, with rendering in LaTeX and
wenzelm@61964
    35
Isabelle fonts: \<Lleftarrow> \<Rrightarrow> \<longlongleftarrow> \<longlongrightarrow> \<longlonglongleftarrow> \<longlonglongrightarrow>
wenzelm@61963

    38
*** Prover IDE -- Isabelle/Scala/jEdit ***
wenzelm@60610
    39
wenzelm@61600
    40
* Completion of symbols via prefix of \<name> or \<^name> or \name is
wenzelm@61600
    41
always possible, independently of the language context. It is never
wenzelm@61600
    42
implicit: a popup will show up unconditionally.
wenzelm@61600
    43
wenzelm@61960
    44
* Additional abbreviations for syntactic completion may be specified in
wenzelm@61960
    45
$ISABELLE_HOME/etc/abbrevs and $ISABELLE_HOME_USER/etc/abbrevs.
wenzelm@61960
    46
wenzelm@60610
    47
* Improved scheduling for urgent print tasks (e.g. command state output,
wenzelm@60610
    48
interactive queries) wrt. long-running background tasks.
wenzelm@60610
    49
wenzelm@60986
    50
* IDE support for the source-level debugger of Poly/ML, to work with
wenzelm@60984
    51
Isabelle/ML and official Standard ML. Configuration option "ML_debugger"
wenzelm@60984
    52
and commands 'ML_file_debug', 'ML_file_no_debug', 'SML_file_debug',
wenzelm@60984
    53
'SML_file_no_debug' control compilation of sources with debugging
wenzelm@60984
    54
information. The Debugger panel allows to set breakpoints (via context
wenzelm@60984
    55
menu), step through stopped threads, evaluate local ML expressions etc.
wenzelm@60984
    56
At least one Debugger view needs to be active to have any effect on the
wenzelm@60984
    57
running ML program.
wenzelm@60984
    58
wenzelm@61173
    59
* The main Isabelle executable is managed as single-instance Desktop
wenzelm@61173
    60
application uniformly on all platforms: Linux, Windows, Mac OS X.
wenzelm@61170
    61
wenzelm@61804
    62
* The State panel manages explicit proof state output, with dynamic
wenzelm@61804
    63
auto-update according to cursor movement. Alternatively, the jEdit
wenzelm@61804
    64
action "isabelle.update-state" (shortcut S+ENTER) triggers manual
wenzelm@61804
    65
update.
wenzelm@61729
    66
wenzelm@61729
    67
* The Output panel no longer shows proof state output by default, to
wenzelm@61729
    68
avoid GUI overcrowding. INCOMPATIBILITY, use the State panel instead or
wenzelm@61729
    69
enable option "editor_output_state".
wenzelm@61215
    70
wenzelm@61804
    71
* The text overview column (status of errors, warnings etc.) is updated
wenzelm@61804
    72
asynchronously, leading to much better editor reactivity. Moreover, the
wenzelm@61804
    73
full document node content is taken into account. The width of the
wenzelm@61804
    74
column is scaled according to the main text area font, for improved
wenzelm@61804
    75
visibility.
wenzelm@61804
    76
wenzelm@61804
    77
* The main text area no longer changes its color hue in outdated
wenzelm@61804
    78
situations. The text overview column takes over the role to indicate
wenzelm@61804
    79
unfinished edits in the PIDE pipeline. This avoids flashing text display
wenzelm@61804
    80
due to ad-hoc updates by auxiliary GUI components, such as the State
wenzelm@61804
    81
panel.
wenzelm@61804
    82
wenzelm@61483
    83
* Action "isabelle-emph" (with keyboard shortcut C+e LEFT) controls
wenzelm@61483
    84
emphasized text style; the effect is visible in document output, not in
wenzelm@61483
    85
the editor.
wenzelm@61483
    86
wenzelm@61483
    87
* Action "isabelle-reset" now uses keyboard shortcut C+e BACK_SPACE,
wenzelm@61483
    88
instead of former C+e LEFT.
wenzelm@61483
    89
wenzelm@61512
    90
* New command-line tool "isabelle jedit_client" allows to connect to
wenzelm@61512
    91
already running Isabelle/jEdit process. This achieves the effect of
wenzelm@61512
    92
single-instance applications seen on common GUI desktops.
wenzelm@61512
    93
wenzelm@61512
    94
* The command-line tool "isabelle jedit" and the isabelle.Main
wenzelm@61512
    95
application wrapper threat the default $USER_HOME/Scratch.thy more
wenzelm@61512
    96
uniformly, and allow the dummy file argument ":" to open an empty buffer
wenzelm@61512
    97
instead.
wenzelm@61512
    98
wenzelm@61530
    99
* The default look-and-feel for Linux is the traditional "Metal", which
wenzelm@61530
   100
works better with GUI scaling for very high-resolution displays (e.g.
wenzelm@61530
   101
4K). Moreover, it is generally more robust than "Nimbus".
wenzelm@61530
   102
wenzelm@60610
   103
wenzelm@61405
   104
*** Document preparation ***
wenzelm@61405
   105
wenzelm@61491
   106
* There is a new short form for antiquotations with a single argument
wenzelm@61491
   107
that is a cartouche: \<^name>\<open>...\<close> is equivalent to @{name \<open>...\<close>} and
wenzelm@61595
   108
\<open>...\<close> without control symbol is equivalent to @{cartouche \<open>...\<close>}.
wenzelm@61595
   109
\<^name> without following cartouche is equivalent to @{name}. The
wenzelm@61501
   110
standard Isabelle fonts provide glyphs to render important control
wenzelm@61501
   111
symbols, e.g. "\<^verbatim>", "\<^emph>", "\<^bold>".
wenzelm@61491
   112
wenzelm@61614
   113
* Antiquotation @{theory_text} prints uninterpreted theory source text
wenzelm@61653
   114
(outer syntax with command keywords etc.). This may be used in the short
wenzelm@61748
   115
form \<^theory_text>\<open>...\<close>.   @{theory_text [display]} supports option "indent".
wenzelm@61748
   116
wenzelm@61748
   117
* @{verbatim [display]} supports option "indent".
wenzelm@61614
   118
wenzelm@61660
   119
* Antiquotation @{doc ENTRY} provides a reference to the given
wenzelm@61660
   120
documentation, with a hyperlink in the Prover IDE.
wenzelm@61660
   121
wenzelm@61623
   122
* Antiquotations @{command}, @{method}, @{attribute} print checked
wenzelm@61623
   123
entities of the Isar language.
wenzelm@61623
   124
wenzelm@61595
   125
* Antiquotations @{noindent}, @{smallskip}, @{medskip}, @{bigskip} with
wenzelm@61595
   126
corresponding control symbols \<^noindent>, \<^smallskip>, \<^medskip>, \<^bigskip> specify spacing formally, using
wenzelm@61595
   127
standard LaTeX macros of the same names.
wenzelm@61595
   128
wenzelm@61491
   129
* Antiquotation @{cartouche} in Isabelle/Pure is the same as @{text}.
wenzelm@61491
   130
Consequently, \<open>...\<close> without any decoration prints literal quasi-formal
wenzelm@61492
   131
text. Command-line tool "isabelle update_cartouches -t" helps to update
wenzelm@61492
   132
old sources, by approximative patching of the content of string and
wenzelm@61492
   133
cartouche tokens seen in theory sources.
wenzelm@61491
   134
wenzelm@61491
   135
* The @{text} antiquotation now ignores the antiquotation option
wenzelm@61491
   136
"source". The given text content is output unconditionally, without any
wenzelm@61491
   137
surrounding quotes etc. Subtle INCOMPATIBILITY, put quotes into the
wenzelm@61494
   138
argument where they are really intended, e.g. @{text \<open>"foo"\<close>}. Initial
wenzelm@61494
   139
or terminal spaces are ignored.
wenzelm@61491
   140
wenzelm@61471
   141
* HTML presentation uses the standard IsabelleText font and Unicode
wenzelm@61471
   142
rendering of Isabelle symbols like Isabelle/Scala/jEdit.  The former
wenzelm@61488
   143
print mode "HTML" loses its special meaning.
wenzelm@61471
   144
wenzelm@61463
   145
* Commands 'paragraph' and 'subparagraph' provide additional section
wenzelm@61463
   146
headings. Thus there are 6 levels of standard headings, as in HTML.
wenzelm@61463
   147
wenzelm@61463
   148
* Text is structured in paragraphs and nested lists, using notation that
wenzelm@61463
   149
is similar to Markdown. The control symbols for list items are as
wenzelm@61463
   150
follows:
wenzelm@61463
   151
wenzelm@61463
   152
  \<^item>  itemize
wenzelm@61463
   153
  \<^enum>  enumerate
wenzelm@61463
   154
  \<^descr>  description
wenzelm@61463
   155
wenzelm@61463
   156
* Command 'text_raw' has been clarified: input text is processed as in
wenzelm@61463
   157
'text' (with antiquotations and control symbols). The key difference is
wenzelm@61463
   158
the lack of the surrounding isabelle markup environment in output.
wenzelm@61405
   159
wenzelm@61473
   160
* Document antiquotations @{emph} and @{bold} output LaTeX source
wenzelm@61653
   161
recursively, adding appropriate text style markup. These may be used in
wenzelm@61653
   162
the short form \<^emph>\<open>...\<close> and \<^bold>\<open>...\<close>.
wenzelm@61473
   163
wenzelm@61571
   164
* Document antiquotation @{footnote} outputs LaTeX source recursively,
wenzelm@61653
   165
marked as \footnote{}. This may be used in the short form \<^footnote>\<open>...\<close>.
wenzelm@61571
   166
wenzelm@61405
   167
wenzelm@60406
   168
*** Isar ***
wenzelm@60406
   169
wenzelm@60406
   170
* Command 'obtain' binds term abbreviations (via 'is' patterns) in the
wenzelm@60406
   171
proof body as well, abstracted over relevant parameters.
wenzelm@60406
   172
wenzelm@60477
   173
* Improved type-inference for theorem statement 'obtains': separate
wenzelm@60477
   174
parameter scope for of each clause.
wenzelm@60477
   175
wenzelm@60408
   176
* Term abbreviations via 'is' patterns also work for schematic
wenzelm@60408
   177
statements: result is abstracted over unknowns.
wenzelm@60408
   178
wenzelm@60414
   179
* Local goals ('have', 'show', 'hence', 'thus') allow structured
wenzelm@61733
   180
rule statements like fixes/assumes/shows in theorem specifications, but
wenzelm@61733
   181
the notation is postfix with keywords 'if' (or 'when') and 'for'. For
wenzelm@60555
   182
example:
wenzelm@60414
   183
wenzelm@60414
   184
  have result: "C x y"
wenzelm@60414
   185
    if "A x" and "B y"
wenzelm@60414
   186
    for x :: 'a and y :: 'a
wenzelm@60414
   187
    <proof>
wenzelm@60414
   188
wenzelm@60449
   189
The local assumptions are bound to the name "that". The result is
wenzelm@60449
   190
exported from context of the statement as usual. The above roughly
wenzelm@60414
   191
corresponds to a raw proof block like this:
wenzelm@60414
   192
wenzelm@60414
   193
  {
wenzelm@60414
   194
    fix x :: 'a and y :: 'a
wenzelm@60449
   195
    assume that: "A x" "B y"
wenzelm@60414
   196
    have "C x y" <proof>
wenzelm@60414
   197
  }
wenzelm@60414
   198
  note result = this
wenzelm@60406
   199
wenzelm@60555
   200
The keyword 'when' may be used instead of 'if', to indicate 'presume'
wenzelm@60555
   201
instead of 'assume' above.
wenzelm@60555
   202
wenzelm@61733
   203
* Assumptions ('assume', 'presume') allow structured rule statements
wenzelm@61733
   204
using 'if' and 'for', similar to 'have' etc. above. For example:
wenzelm@61658
   205
wenzelm@61658
   206
  assume result: "C x y"
wenzelm@61658
   207
    if "A x" and "B y"
wenzelm@61658
   208
    for x :: 'a and y :: 'a
wenzelm@61658
   209
wenzelm@61658
   210
This assumes "\<And>x y::'a. A x \<Longrightarrow> B y \<Longrightarrow> C x y" and produces a general
wenzelm@61658
   211
result as usual: "A ?x \<Longrightarrow> B ?y \<Longrightarrow> C ?x ?y".
wenzelm@61658
   212
wenzelm@61658
   213
Vacuous quantification in assumptions is omitted, i.e. a for-context
wenzelm@61658
   214
only effects propositions according to actual use of variables. For
wenzelm@61658
   215
example:
wenzelm@61658
   216
wenzelm@61658
   217
  assume "A x" and "B y" for x and y
wenzelm@61658
   218
wenzelm@61658
   219
is equivalent to:
wenzelm@61658
   220
wenzelm@61658
   221
  assume "\<And>x. A x" and "\<And>y. B y"
wenzelm@61658
   222
wenzelm@60595
   223
* The meaning of 'show' with Pure rule statements has changed: premises
wenzelm@60595
   224
are treated in the sense of 'assume', instead of 'presume'. This means,
wenzelm@60595
   225
a goal like "\<And>x. A x \<Longrightarrow> B x \<Longrightarrow> C x" can be solved completely as follows:
wenzelm@60595
   226
wenzelm@60595
   227
  show "\<And>x. A x \<Longrightarrow> B x \<Longrightarrow> C x"
wenzelm@60595
   228
wenzelm@60595
   229
or:
wenzelm@60595
   230
wenzelm@60595
   231
  show "C x" if "A x" "B x" for x
wenzelm@60595
   232
wenzelm@60595
   233
Rare INCOMPATIBILITY, the old behaviour may be recovered as follows:
wenzelm@60595
   234
wenzelm@60595
   235
  show "C x" when "A x" "B x" for x
wenzelm@60595
   236
wenzelm@60406
   237
* New command 'supply' supports fact definitions during goal refinement
wenzelm@60406
   238
('apply' scripts).
wenzelm@60406
   239
wenzelm@60459
   240
* New command 'consider' states rules for generalized elimination and
wenzelm@60459
   241
case splitting. This is like a toplevel statement "theorem obtains" used
wenzelm@60459
   242
within a proof body; or like a multi-branch 'obtain' without activation
wenzelm@60459
   243
of the local context elements yet.
wenzelm@60459
   244
wenzelm@60455
   245
* Proof method "cases" allows to specify the rule as first entry of
wenzelm@60455
   246
chained facts.  This is particularly useful with 'consider':
wenzelm@60455
   247
wenzelm@60455
   248
  consider (a) A | (b) B | (c) C <proof>
wenzelm@60455
   249
  then have something
wenzelm@60455
   250
  proof cases
wenzelm@60455
   251
    case a
wenzelm@60455
   252
    then show ?thesis <proof>
wenzelm@60455
   253
  next
wenzelm@60455
   254
    case b
wenzelm@60455
   255
    then show ?thesis <proof>
wenzelm@60455
   256
  next
wenzelm@60455
   257
    case c
wenzelm@60455
   258
    then show ?thesis <proof>
wenzelm@60455
   259
  qed
wenzelm@60455
   260
wenzelm@60565
   261
* Command 'case' allows fact name and attribute specification like this:
wenzelm@60565
   262
wenzelm@60565
   263
  case a: (c xs)
wenzelm@60565
   264
  case a [attributes]: (c xs)
wenzelm@60565
   265
wenzelm@60565
   266
Facts that are introduced by invoking the case context are uniformly
wenzelm@60565
   267
qualified by "a"; the same name is used for the cumulative fact. The old
wenzelm@60565
   268
form "case (c xs) [attributes]" is no longer supported. Rare
wenzelm@60565
   269
INCOMPATIBILITY, need to adapt uses of case facts in exotic situations,
wenzelm@60565
   270
and always put attributes in front.
wenzelm@60565
   271
wenzelm@60618
   272
* The standard proof method of commands 'proof' and '..' is now called

* Command 'subgoal' allows to impose some structure on backward

* The undocumented feature of implicit cases goal1, goal2, goal3, etc.
wenzelm@60617
   307
is marked as legacy, and will be removed eventually. The proof method
wenzelm@60617
   308
"goals" achieves a similar effect within regular Isar; often it can be
wenzelm@60617
   309
done more adequately by other means (e.g. 'consider').
wenzelm@60581

wenzelm@60551

* Nesting of Isar goal structure has been clarified: the context after
wenzelm@60551

the initial backwards refinement is retained for the whole proof, within
wenzelm@60551
   313
all its context sections (as indicated via 'next'). This is e.g.
wenzelm@60551
   314
relevant for 'using', 'including', 'supply':
wenzelm@60551
   315
wenzelm@60551
   316
  have "A \<and> A" if a: A for A

wenzelm@61606
   331
of the command. Previously, for 'locale' and 'sublocale' the default was
wenzelm@61606
   332
optional ('?'). The old synatx '!' has been discontinued.

* More gentle suppression of syntax along locale morphisms while
ballarin@61701
   339
printing terms.  Previously 'abbreviation' and 'notation' declarations
ballarin@61701
   340
would be suppressed for morphisms except term identity.  Now
ballarin@61701
   341
'abbreviation' is also kept for morphims that only change the involved
ballarin@61701
   342
parameters, and only 'notation' is suppressed.  This can be of great
ballarin@61701
   343
help when working with complex locale hierarchies, because proof
ballarin@61701
   344
states are displayed much more succinctly.  It also means that only
ballarin@61701
   345
notation needs to be redeclared if desired, as illustrated by this
ballarin@61701
   346
example:
ballarin@61701
   347
ballarin@61701
   348
  locale struct = fixes composition :: "'a => 'a => 'a" (infixl "\<cdot>" 65)

* Commands 'inductive' and 'inductive_set' work better when names for

   436
intro rules are omitted: the "cases" and "induct" rules no longer
wenzelm@61308

declare empty case_names, but no case_names at all. This allows to use

wenzelm@61269
   440
* The 'typedef' command has been upgraded from a partially checked
wenzelm@61269
   441
"axiomatization", to a full definitional specification that takes the
wenzelm@61269
   442
global collection of overloaded constant / type definitions into
wenzelm@61269
   443
account. Type definitions with open dependencies on overloaded
wenzelm@61269
   444
definitions need to be specified as "typedef (overloaded)". This
wenzelm@61269
   445
provides extra robustness in theory construction. Rare INCOMPATIBILITY.

wenzelm@61118

lp15@61426
   541
  - new methods for interactive debugging of 'transfer' and
kuncar@61370
   542
    'transfer_prover': 'transfer_start', 'transfer_step', 'transfer_end',

* Division on integers is bootstrapped directly from division on
haftmann@60868
   546
naturals and uses generic numeral algorithm for computations.
haftmann@60868
   547
Slight INCOMPATIBILITY, simproc numeral_divmod replaces and generalizes
haftmann@60868
   548
former simprocs binary_int_div and binary_int_mod
haftmann@60868
   549
haftmann@60516
   550
* Tightened specification of class semiring_no_zero_divisors.  Slight
haftmann@60516
   551
INCOMPATIBILITY.
haftmann@60516
   552
haftmann@60688
   553
* Class algebraic_semidom introduces common algebraic notions of
haftmann@60688
   554
integral (semi)domains, particularly units.  Although
haftmann@60517
   555
logically subsumed by fields, is is not a super class of these
haftmann@60517
   556
in order not to burden fields with notions that are trivial there.
haftmann@60688
   557
haftmann@60688
   558
* Class normalization_semidom specifies canonical representants
haftmann@60688
   559
for equivalence classes of associated elements in an integral
haftmann@60688
   560
(semi)domain.  This formalizes associated elements as well.
haftmann@60688
   561
haftmann@60688
   562
* Abstract specification of gcd/lcm operations in classes semiring_gcd,
haftmann@60688
   563
semiring_Gcd, semiring_Lcd.  Minor INCOMPATIBILITY: facts gcd_nat.commute
haftmann@60688
   564
and gcd_int.commute are subsumed by gcd.commute, as well as gcd_nat.assoc
haftmann@60688
   565
and gcd_int.assoc by gcd.assoc.
haftmann@60517
   566
haftmann@60429
   567
* Former constants Fields.divide (_ / _) and Divides.div (_ div _)
haftmann@60354
   568
are logically unified to Rings.divide in syntactic type class
haftmann@60429
   569
Rings.divide, with infix syntax (_ div _).  Infix syntax (_ / _)
haftmann@60429
   570
for field division is added later as abbreviation in class Fields.inverse.
haftmann@60516
   571
INCOMPATIBILITY,  instantiations must refer to Rings.divide rather
haftmann@60429
   572
than the former separate constants, hence infix syntax (_ / _) is usually
haftmann@60429
   573
not available during instantiation.
haftmann@60354
   574
Andreas@61628
   575
* New cancellation simprocs for boolean algebras to cancel
Andreas@61628
   576
complementary terms for sup and inf. For example, "sup x (sup y (- x))"
Andreas@61628
   577
simplifies to "top". INCOMPATIBILITY.
Andreas@61628

* Library/Multiset:
Mathias@60397
   580
  - Renamed multiset inclusion operators:
Mathias@60397

      \<subseteq> ~> \<subseteq>#
Mathias@60397
   586
    INCOMPATIBILITY.
Mathias@60397
   587
  - "'a multiset" is no longer an instance of the "order",
Mathias@60397
   588
    "ordered_ab_semigroup_add_imp_le", "ordered_cancel_comm_monoid_diff",
Mathias@60397
   589
    "semilattice_inf", and "semilattice_sup" type classes. The theorems
Mathias@60397
   590
    previously provided by these type classes (directly or indirectly)
Mathias@60397
   591
    are now available through the "subset_mset" interpretation
Mathias@60397
   592
    (e.g. add_mono ~> subset_mset.add_mono).
Mathias@60397
   593
    INCOMPATIBILITY.
nipkow@60497
   594
  - Renamed conversions:
nipkow@60515
   595
      multiset_of ~> mset
nipkow@60515
   596
      multiset_of_set ~> mset_set

      set_of ~> set_mset
nipkow@60497
   598
    INCOMPATIBILITY
Mathias@60398
   599
  - Renamed lemmas:

      mset_le_def ~> subseteq_mset_def
Mathias@60398
   601
      mset_less_def ~> subset_mset_def

   619
wenzelm@60523
   620
* Theory Library/Old_Recdef: discontinued obsolete 'defer_recdef'
wenzelm@60523
   621
command. Minor INCOMPATIBILITY, use 'function' instead.
wenzelm@60523
   622
wenzelm@61681
   623
* Inductive definitions ('inductive', 'coinductive', etc.) expose
wenzelm@61681
   624
low-level facts of the internal construction only if the option
wenzelm@61681
   625
"inductive_defs" is enabled. This refers to the internal predicate
wenzelm@61681
   626
definition and its monotonicity result. Rare INCOMPATIBILITY.
wenzelm@61681
   627
wenzelm@61121
   628
* Recursive function definitions ('fun', 'function', 'partial_function')
wenzelm@61681
   629
expose low-level facts of the internal construction only if the option
wenzelm@61681
   630
"function_defs" is enabled. Rare INCOMPATIBILITY.
wenzelm@61121

* HOL-Statespace: command 'statespace' uses mandatory qualifier for
wenzelm@61606
   640
import of parent, as for general 'locale' expressions. INCOMPATIBILITY,
wenzelm@61606
   641
remove '!' and add '?' as required.

   645
wenzelm@61922
   646
* Pretty printing of Poly/ML compiler output in Isabelle has been
wenzelm@61922
   647
improved: proper treatment of break offsets and blocks with consistent
wenzelm@61922
   648
breaks.
wenzelm@61922
   649
wenzelm@61841
   650
* Isar proof methods are based on a slightly more general type
wenzelm@61841
   651
context_tactic, which allows to change the proof context dynamically
wenzelm@61841
   652
(e.g. to update cases) and indicate explicit Seq.Error results. Former
wenzelm@61841
   653
METHOD_CASES is superseded by CONTEXT_METHOD; further combinators are
wenzelm@61841
   654
provided in src/Pure/Isar/method.ML for convenience. INCOMPATIBILITY.
wenzelm@61841
   655
wenzelm@61597

* Antiquotation @{undefined} or \<^undefined> inlines (raise Match).
wenzelm@61597
   657
wenzelm@61268
   658
* The auxiliary module Pure/display.ML has been eliminated. Its
wenzelm@61268
   659
elementary thm print operations are now in Pure/more_thm.ML and thus
wenzelm@61268
   660
called Thm.pretty_thm, Thm.string_of_thm etc. INCOMPATIBILITY.
wenzelm@61268
   661
wenzelm@61144
   662
* Simproc programming interfaces have been simplified:
wenzelm@61144
   663
Simplifier.make_simproc and Simplifier.define_simproc supersede various
wenzelm@61144
   664
forms of Simplifier.mk_simproc, Simplifier.simproc_global etc. Note that
wenzelm@61144
   665
term patterns for the left-hand sides are specified with implicitly
wenzelm@61144
   666
fixed variables, like top-level theorem statements. INCOMPATIBILITY.
wenzelm@61144
   667
wenzelm@60802
   668
* Instantiation rules have been re-organized as follows:
wenzelm@60802
   669
wenzelm@60802
   670
  Thm.instantiate  (*low-level instantiation with named arguments*)
wenzelm@60802
   671
  Thm.instantiate' (*version with positional arguments*)
wenzelm@60802
   672
wenzelm@60802
   673
  Drule.infer_instantiate  (*instantiation with type inference*)
wenzelm@60802
   674
  Drule.infer_instantiate'  (*version with positional arguments*)
wenzelm@60802
   675
wenzelm@60802
   676
The LHS only requires variable specifications, instead of full terms.
wenzelm@60802
   677
Old cterm_instantiate is superseded by infer_instantiate.
wenzelm@60802
   678
INCOMPATIBILITY, need to re-adjust some ML names and types accordingly.
wenzelm@60802
   679
wenzelm@60793
   680
* Old tactic shorthands atac, rtac, etac, dtac, ftac have been
wenzelm@60793
   681
discontinued. INCOMPATIBILITY, use regular assume_tac, resolve_tac etc.
wenzelm@60793
   682
instead (with proper context).
wenzelm@60642
   683
wenzelm@60642
   684
* Thm.instantiate (and derivatives) no longer require the LHS of the
wenzelm@60642
   685
instantiation to be certified: plain variables are given directly.
wenzelm@60642
   686
wenzelm@60707
   687
* Subgoal.SUBPROOF and Subgoal.FOCUS combinators use anonymous
wenzelm@60707
   688
quasi-bound variables (like the Simplifier), instead of accidentally
wenzelm@60707
   689
named local fixes. This has the potential to improve stability of proof
wenzelm@60707
   690
tools, but can also cause INCOMPATIBILITY for tools that don't observe
wenzelm@60707
   691
the proof context discipline.
wenzelm@60707
   692
wenzelm@61887
   693
* The following combinators for low-level profiling of the ML runtime
wenzelm@61887
   694
system are available:
wenzelm@61887
   695
wenzelm@61887
   696
  profile_time          (*CPU time*)
wenzelm@61887
   697
  profile_time_thread   (*CPU time on this thread*)
wenzelm@61887
   698
  profile_allocations   (*overall heap allocations*)
wenzelm@61887

*** System ***
wenzelm@60983
   702
wenzelm@61958
   703
* Command-line tool "isabelle console" enables print mode "ASCII".
wenzelm@61958
   704
wenzelm@61602
   705
* Global session timeout is multiplied by timeout_scale factor. This
wenzelm@61602
   706
allows to adjust large-scale tests (e.g. AFP) to overall hardware
wenzelm@61602
   707
performance.
wenzelm@61602
   708
wenzelm@61174
   709
* Property values in etc/symbols may contain spaces, if written with the
wenzelm@61174
   710
replacement character "␣" (Unicode point 0x2324).  For example:
wenzelm@61174
   711
wenzelm@61602
   712
    \<star>  code: 0x0022c6  group: operator  font: Deja␣Vu␣Sans␣Mono
wenzelm@61174
   713
wenzelm@61216
   714
* Command-line tool "isabelle update_then" expands old Isar command
wenzelm@61216
   715
conflations:
wenzelm@61216
   716
wenzelm@61216
   717
    hence  ~>  then have
wenzelm@61216
   718
    thus   ~>  then show
wenzelm@61216
   719
wenzelm@61216
   720
This syntax is more orthogonal and improves readability and
wenzelm@61216
   721
maintainability of proofs.
wenzelm@61216
   722
wenzelm@61158
   723
* Poly/ML default platform architecture may be changed from 32bit to
wenzelm@61158
   724
64bit via system option ML_system_64. A system restart (and rebuild)
wenzelm@61158
   725
is required after change.
wenzelm@61158
   726
wenzelm@61796
   727
* Poly/ML 5.6 runs natively on x86-windows and x86_64-windows, which
wenzelm@61796
   728
both allow larger heap space than former x86-cygwin.
wenzelm@60983
   729
wenzelm@60996
   730
* Java runtime environment for x86_64-windows allows to use larger heap
wenzelm@60996
   731
space.
wenzelm@60996
   732
wenzelm@61135
   733
* Java runtime options are determined separately for 32bit vs. 64bit
wenzelm@61135
   734
platforms as follows.
wenzelm@61135
   735
wenzelm@61135
   736
  - Isabelle desktop application: platform-specific files that are
wenzelm@61135

* Bash shell function "jvmpath" has been renamed to "platform_path": it
wenzelm@61294
   747
is relevant both for Poly/ML and JVM processes.
wenzelm@61294
   748
wenzelm@61567
   749
* Heap images are 10-15% smaller due to less wasteful persistent theory

wenzelm@59939
   759
* Local theory specification commands may have a 'private' or
wenzelm@59990
   760
'qualified' modifier to restrict name space accesses to the local scope,
wenzelm@59939
   761
as provided by some "context begin ... end" block. For example:
wenzelm@59926
   762
wenzelm@59926

wenzelm@59926
   764

wenzelm@59926
   776
wenzelm@59901
   777
* Command 'experiment' opens an anonymous locale context with private
wenzelm@59901
   778
naming policy.
wenzelm@59901
   779
wenzelm@59951
   780
* Command 'notepad' requires proper nesting of begin/end and its proof
wenzelm@59951
   781
structure in the body: 'oops' is no longer supported here. Minor
wenzelm@59951
   782
INCOMPATIBILITY, use 'sorry' instead.
wenzelm@59951
   783
wenzelm@59951
   784
* Command 'named_theorems' declares a dynamic fact within the context,
wenzelm@59951
   785
together with an attribute to maintain the content incrementally. This
wenzelm@59951
   786
supersedes functor Named_Thms in Isabelle/ML, but with a subtle change
wenzelm@59951
   787
of semantics due to external visual order vs. internal reverse order.
wenzelm@59951
   788
wenzelm@59951
   789
* 'find_theorems': search patterns which are abstractions are
wenzelm@59951
   790
schematically expanded before search. Search results match the naive
wenzelm@59951
   791
expectation more closely, particularly wrt. abbreviations.
wenzelm@59951
   792
INCOMPATIBILITY.
wenzelm@59648
   793
wenzelm@59569
   794
* Commands 'method_setup' and 'attribute_setup' now work within a local
wenzelm@59569
   795
theory context.
wenzelm@57941
   796
wenzelm@58928
   797
* Outer syntax commands are managed authentically within the theory
wenzelm@59569
   798
context, without implicit global state. Potential for accidental
wenzelm@58928
   799
INCOMPATIBILITY, make sure that required theories are really imported.
wenzelm@58928
   800
wenzelm@60116
   801
* Historical command-line terminator ";" is no longer accepted (and
wenzelm@60116
   802
already used differently in Isar). Minor INCOMPATIBILITY, use "isabelle
wenzelm@60116
   803
update_semicolons" to remove obsolete semicolons from old theory

wenzelm@59951
   806
* Structural composition of proof methods (meth1; meth2) in Isar

corresponds to (tac1 THEN_ALL_NEW tac2) in ML.
haftmann@59105
   808
wenzelm@60119
   809
* The Eisbach proof method language allows to define new proof methods
wenzelm@60119
   810
by combining existing ones with their usual syntax. The "match" proof
wenzelm@60119
   811
method provides basic fact/term matching in addition to
wenzelm@60119
   812
premise/conclusion matching through Subgoal.focus, and binds fact names
wenzelm@60288
   813
from matches as well as term patterns within matches. The Isabelle

* Improved folding mode "isabelle" based on Isar syntax. Alternatively,
wenzelm@59569
   821
the "sidekick" mode may be used for document structure.
wenzelm@59569
   822
wenzelm@59569
   823
* Extended bracket matching based on Isar language structure. System
wenzelm@59569
   824
option jedit_structure_limit determines maximum number of lines to scan
wenzelm@59569
   825
in the buffer.
wenzelm@58758
   826
wenzelm@58540
   827
* Support for BibTeX files: context menu, context-sensitive token
wenzelm@58540
   828
marker, SideKick parser.
wenzelm@58524
   829
wenzelm@58551
   830
* Document antiquotation @{cite} provides formal markup, which is
wenzelm@60265
   831
interpreted semi-formally based on .bib files that happen to be open in
wenzelm@60265
   832
the editor (hyperlinks, completion etc.).
wenzelm@58551
   833
wenzelm@58785
   834
* Less waste of vertical space via negative line spacing (see Global
wenzelm@58785
   835
Options / Text Area).
wenzelm@58785
   836
wenzelm@60091
   837
* Improved graphview panel with optional output of PNG or PDF, for
wenzelm@60273
   838
display of 'thy_deps', 'class_deps' etc.
wenzelm@60010
   839
wenzelm@60116
   840
* The commands 'thy_deps' and 'class_deps' allow optional bounds to
wenzelm@60116
   841
restrict the visualized hierarchy.
wenzelm@60095
   842
wenzelm@60072
   843
* Improved scheduling for asynchronous print commands (e.g. provers
wenzelm@60072
   844
managed by the Sledgehammer panel) wrt. ongoing document processing.

*** Document preparation ***
wenzelm@59951
   848
wenzelm@59951
   849
* Document markup commands 'chapter', 'section', 'subsection',
wenzelm@59951
   850
'subsubsection', 'text', 'txt', 'text_raw' work uniformly in any
wenzelm@59951
   851
context, even before the initial 'theory' command. Obsolete proof
wenzelm@59951
   852
commands 'sect', 'subsect', 'subsubsect', 'txt_raw' have been
wenzelm@59951
   853
discontinued, use 'section', 'subsection', 'subsubsection', 'text_raw'
wenzelm@59951
   854
instead. The old 'header' command is still retained for some time, but
wenzelm@59951
   855
should be replaced by 'chapter', 'section' etc. (using "isabelle
wenzelm@59951
   856
update_header"). Minor INCOMPATIBILITY.
wenzelm@59951
   857
wenzelm@60010
   858
* Official support for "tt" style variants, via \isatt{...} or
wenzelm@60010
   859
\begin{isabellett}...\end{isabellett}. The somewhat fragile \verb or
wenzelm@60010
   860
verbatim environment of LaTeX is no longer used. This allows @{ML} etc.
wenzelm@60010
   861
as argument to other macros (such as footnotes).
wenzelm@60010
   862
wenzelm@60010
   863
* Document antiquotation @{verbatim} prints ASCII text literally in "tt"
wenzelm@60010
   864
style.
wenzelm@60010
   865
wenzelm@60010
   866
* Discontinued obsolete option "document_graph": session_graph.pdf is
wenzelm@60010
   867
produced unconditionally for HTML browser_info and PDF-LaTeX document.
wenzelm@60010
   868
wenzelm@59951
   869
* Diagnostic commands and document markup commands within a proof do not
wenzelm@59951
   870
affect the command tag for output. Thus commands like 'thm' are subject
wenzelm@59951
   871
to proof document structure, and no longer "stick out" accidentally.
wenzelm@59951
   872
Commands 'text' and 'txt' merely differ in the LaTeX style, not their
wenzelm@59951
   873
tags. Potential INCOMPATIBILITY in exotic situations.
wenzelm@59951
   874
wenzelm@59951
   875
* System option "pretty_margin" is superseded by "thy_output_margin",
wenzelm@59951
   876
which is also accessible via document antiquotation option "margin".
wenzelm@59951
   877
Only the margin for document output may be changed, but not the global
wenzelm@59951
   878
pretty printing: that is 76 for plain console output, and adapted
wenzelm@59951
   879
dynamically in GUI front-ends. Implementations of document
wenzelm@59951
   880
antiquotations need to observe the margin explicitly according to
wenzelm@59951
   881
Thy_Output.string_of_margin. Minor INCOMPATIBILITY.
wenzelm@59951
   882
wenzelm@60299
   883
* Specification of 'document_files' in the session ROOT file is
wenzelm@60299
   884
mandatory for document preparation. The legacy mode with implicit
wenzelm@60299
   885
copying of the document/ directory is no longer supported. Minor
wenzelm@60299
   886
INCOMPATIBILITY.

*** Pure ***
haftmann@58202
   890
wenzelm@59835
   891
* Proof methods with explicit instantiation ("rule_tac", "subgoal_tac"
wenzelm@59835
   892
etc.) allow an optional context of local variables ('for' declaration):
wenzelm@59835
   893
these variables become schematic in the instantiated theorem; this
wenzelm@59835
   894
behaviour is analogous to 'for' in attributes "where" and "of".
wenzelm@59835
   895
Configuration option rule_insts_schematic (default false) controls use
wenzelm@59835
   896
of schematic variables outside the context. Minor INCOMPATIBILITY,
wenzelm@59835
   897
declare rule_insts_schematic = true temporarily and update to use local
wenzelm@59835
   898
variable declarations or dummy patterns instead.
wenzelm@59835
   899
wenzelm@60010
   900
* Explicit instantiation via attributes "where", "of", and proof methods
wenzelm@60010
   901
"rule_tac" with derivatives like "subgoal_tac" etc. admit dummy patterns
wenzelm@60010
   902
("_") that stand for anonymous local variables.
wenzelm@60010
   903
wenzelm@59951
   904
* Generated schematic variables in standard format of exported facts are
wenzelm@59951
   905
incremented to avoid material in the proof context. Rare
wenzelm@59951
   906
INCOMPATIBILITY, explicit instantiation sometimes needs to refer to
wenzelm@59951
   907
different index.
wenzelm@59951
   908
wenzelm@60011
   909
* Lexical separation of signed and unsigned numerals: categories "num"
wenzelm@60011
   910
and "float" are unsigned. INCOMPATIBILITY: subtle change in precedence
wenzelm@60011
   911
of numeral signs, particularly in expressions involving infix syntax
wenzelm@60011
   912
like "(- 1) ^ n".
haftmann@58410
   913
wenzelm@58421
   914
* Old inner token category "xnum" has been discontinued.  Potential
wenzelm@58421
   915
INCOMPATIBILITY for exotic syntax: may use mixfix grammar with "num"
wenzelm@58421
   916
token category instead.

* New (co)datatype package:
blanchet@58374
   922
  - The 'datatype_new' command has been renamed 'datatype'. The old
blanchet@58374
   923
    command of that name is now called 'old_datatype' and is provided
blanchet@58374
   924
    by "~~/src/HOL/Library/Old_Datatype.thy". See
blanchet@58374
   925
    'isabelle doc datatypes' for information on porting.

blanchet@58192
   942
  - The "no_code" option to "free_constructors", "datatype_new", and
blanchet@58192
   943
    "codatatype" has been renamed "plugins del: code".
blanchet@58192
   944
    INCOMPATIBILITY.
blanchet@58044
   945
  - The rules "set_empty" have been removed. They are easy
blanchet@58044
   946
    consequences of other set rules "by auto".
blanchet@58044
   947
    INCOMPATIBILITY.
blanchet@58044
   948
  - The rule "set_cases" is now registered with the "[cases set]"
blanchet@57990
   949
    attribute. This can influence the behavior of the "cases" proof
blanchet@57990
   950
    method when more than one case rule is applicable (e.g., an
blanchet@57990
   951
    assumption is of the form "w : set ws" and the method "cases w"
blanchet@57990
   952
    is invoked). The solution is to specify the case rule explicitly
blanchet@57990
   953
    (e.g. "cases w rule: widget.exhaust").
blanchet@57990
   954
    INCOMPATIBILITY.

   964
    option) is now performed by the BNF package. Theories Lifting_Sum,
wenzelm@60115
   965
    Lifting_Product and Lifting_Option from Main became obsolete and
wenzelm@60115
   966
    were removed. Changed definitions of the relators rel_prod and
wenzelm@60115
   967
    rel_sum (using inductive).
traytel@60112
   968
    INCOMPATIBILITY: use rel_prod.simps and rel_sum.simps instead
wenzelm@60115
   969
    of rel_prod_def and rel_sum_def.
wenzelm@60115
   970
    Minor INCOMPATIBILITY: (rarely used by name) transfer theorem names
wenzelm@60115
   971
    changed (e.g. map_prod_transfer ~> prod.map_transfer).
wenzelm@60261

   978
  - The old 'datatype' command has been renamed 'old_datatype', and
blanchet@58374
   979
    'rep_datatype' has been renamed 'old_rep_datatype'. They are

blanchet@57983
   989
blanchet@59039
   990
* Nitpick:
wenzelm@60011
   991
  - Fixed soundness bug related to the strict and non-strict subset
blanchet@59039
   992
    operations.
blanchet@59039
   993
blanchet@57737
   994
* Sledgehammer:
blanchet@59511
   995
  - CVC4 is now included with Isabelle instead of CVC3 and run by
blanchet@59511
   996
    default.
blanchet@59965
   997
  - Z3 is now always enabled by default, now that it is fully open
blanchet@59965
   998
    source. The "z3_non_commercial" option is discontinued.
blanchet@57737
   999
  - Minimization is now always enabled by default.
wenzelm@60011
  1000
    Removed sub-command:

  1001
      min
blanchet@59967
  1002
  - Proof reconstruction, both one-liners and Isar, has been
blanchet@59039
  1003
    dramatically improved.
blanchet@59039
  1004
  - Improved support for CVC4 and veriT.
blanchet@57737
  1005
blanchet@58062
  1006
* Old and new SMT modules:
blanchet@58067
  1007
  - The old 'smt' method has been renamed 'old_smt' and moved to
wenzelm@59569
  1008
    'src/HOL/Library/Old_SMT.thy'. It is provided for compatibility,
wenzelm@59569
  1009
    until applications have been ported to use the new 'smt' method. For
wenzelm@59569
  1010
    the method to work, an older version of Z3 (e.g. Z3 3.2 or 4.0) must
wenzelm@59569
  1011
    be installed, and the environment variable "OLD_Z3_SOLVER" must
wenzelm@59569
  1012
    point to it.
blanchet@58062
  1013
    INCOMPATIBILITY.
blanchet@58067

  - The 'smt2' method has been renamed 'smt'.
blanchet@58060
  1015
    INCOMPATIBILITY.
wenzelm@59569
  1016
  - New option 'smt_reconstruction_step_timeout' to limit the
wenzelm@59569
  1017
    reconstruction time of Z3 proof steps in the new 'smt' method.
boehmes@59216
  1018
  - New option 'smt_statistics' to display statistics of the new 'smt'
boehmes@59216
  1019
    method, especially runtime statistics of Z3 proof reconstruction.
blanchet@58060
  1020
wenzelm@60261
  1021
* Lifting: command 'lift_definition' allows to execute lifted constants
wenzelm@60261
  1022
that have as a return type a datatype containing a subtype. This
wenzelm@60261
  1023
overcomes long-time limitations in the area of code generation and
wenzelm@60261
  1024
lifting, and avoids tedious workarounds.
kuncar@60258
  1025
wenzelm@60010
  1026
* Command and antiquotation "value" provide different evaluation slots
wenzelm@60010
  1027
(again), where the previous strategy (NBE after ML) serves as default.
wenzelm@60010
  1028
Minor INCOMPATIBILITY.
wenzelm@60010
  1029
wenzelm@60010
  1030
* Add NO_MATCH-simproc, allows to check for syntactic non-equality.
wenzelm@60010
  1031
wenzelm@60010
  1032
* field_simps: Use NO_MATCH-simproc for distribution rules, to avoid
wenzelm@60010
  1033
non-termination in case of distributing a division. With this change
wenzelm@60010
  1034
field_simps is in some cases slightly less powerful, if it fails try to
wenzelm@60010
  1035
add algebra_simps, or use divide_simps. Minor INCOMPATIBILITY.
wenzelm@60010
  1036
wenzelm@60010
  1037
* Separate class no_zero_divisors has been given up in favour of fully
wenzelm@60010
  1038
algebraic semiring_no_zero_divisors. INCOMPATIBILITY.
wenzelm@60010
  1039
wenzelm@60010
  1040
* Class linordered_semidom really requires no zero divisors.
wenzelm@60010
  1041
INCOMPATIBILITY.
wenzelm@60010
  1042
wenzelm@60010
  1043
* Classes division_ring, field and linordered_field always demand
wenzelm@60010
  1044
"inverse 0 = 0". Given up separate classes division_ring_inverse_zero,
wenzelm@60010
  1045
field_inverse_zero and linordered_field_inverse_zero. INCOMPATIBILITY.
wenzelm@60010
  1046
wenzelm@60010
  1047
* Classes cancel_ab_semigroup_add / cancel_monoid_add specify explicit
wenzelm@60010
  1048
additive inverse operation. INCOMPATIBILITY.
wenzelm@60010
  1049
lp15@60020
  1050
* Complex powers and square roots. The functions "ln" and "powr" are now
wenzelm@60025
  1051
overloaded for types real and complex, and 0 powr y = 0 by definition.
wenzelm@60025
  1052
INCOMPATIBILITY: type constraints may be necessary.
lp15@60020
  1053
wenzelm@60010
  1054
* The functions "sin" and "cos" are now defined for any type of sort
wenzelm@60010
  1055
"{real_normed_algebra_1,banach}" type, so in particular on "real" and
wenzelm@60010
  1056
"complex" uniformly. Minor INCOMPATIBILITY: type constraints may be
wenzelm@60010
  1057
needed.
wenzelm@60010
  1058
wenzelm@60010
  1059
* New library of properties of the complex transcendental functions sin,
wenzelm@60010
  1060
cos, tan, exp, Ln, Arctan, Arcsin, Arccos. Ported from HOL Light.
wenzelm@60010
  1061
wenzelm@60010
  1062
* The factorial function, "fact", now has type "nat => 'a" (of a sort
wenzelm@60010
  1063
that admits numeric types including nat, int, real and complex.
wenzelm@60010
  1064
INCOMPATIBILITY: an expression such as "fact 3 = 6" may require a type
wenzelm@60010
  1065
constraint, and the combination "real (fact k)" is likely to be
wenzelm@60010
  1066
unsatisfactory. If a type conversion is still necessary, then use
wenzelm@60010
  1067
"of_nat (fact k)" or "real_of_nat (fact k)".
wenzelm@60010
  1068
wenzelm@60010
  1069
* Removed functions "natfloor" and "natceiling", use "nat o floor" and
wenzelm@60010
  1070
"nat o ceiling" instead. A few of the lemmas have been retained and
wenzelm@60010
  1071
adapted: in their names "natfloor"/"natceiling" has been replaced by
wenzelm@60010
  1072
"nat_floor"/"nat_ceiling".

* Fact consolidation: even_less_0_iff is subsumed by
wenzelm@60010
  1088
double_add_less_zero_iff_single_add_less_zero (simp by default anyway).
wenzelm@60010
  1089
wenzelm@60010

wenzelm@60010
  1095
wenzelm@60010
  1096
* "even" and "odd" are mere abbreviations for "2 dvd _" and "~ 2 dvd _"

* Library/Multiset:
blanchet@59813
  1119
  - Introduced "replicate_mset" operation.
blanchet@59813
  1120
  - Introduced alternative characterizations of the multiset ordering in
blanchet@59813
  1121
    "Library/Multiset_Order".
blanchet@59958
  1122
  - Renamed multiset ordering:

blanchet@59986
  1129
      <#, \<subset># abbreviate < (strict subset)
blanchet@59986
  1130
      <=#, \<le>#, \<subseteq># abbreviate <= (subset or equal)
blanchet@59986
  1131
    INCOMPATIBILITY.
blanchet@59813
  1132
  - Renamed
blanchet@59813

* Library/Sum_of_Squares: simplified and improved "sos" method. Always
wenzelm@60010
  1150
use local CSDP executable, which is much faster than the NEOS server.
wenzelm@60010
  1151
The "sos_cert" functionality is invoked as "sos" with additional
wenzelm@60010
  1152
argument. Minor INCOMPATIBILITY.

wenzelm@60010
  1154
* HOL-Decision_Procs: New counterexample generator quickcheck
wenzelm@60010
  1155
[approximation] for inequalities of transcendental functions. Uses
wenzelm@60010
  1156
hardware floating point arithmetic to randomly discover potential
wenzelm@60011
  1157
counterexamples. Counterexamples are certified with the "approximation"

* HOL-Probability: Reworked measurability prover
wenzelm@60011
  1162
  - applies destructor rules repeatedly
hoelzl@59354
  1163
  - removed application splitting (replaced by destructor rule)
wenzelm@59569
  1164
  - added congruence rules to rewrite measure spaces under the sets

*** ML ***
blanchet@58066
  1172
wenzelm@60010
  1173
* Subtle change of name space policy: undeclared entries are now
wenzelm@60010
  1174
considered inaccessible, instead of accessible via the fully-qualified
wenzelm@60010
  1175
internal name. This mainly affects Name_Space.intern (and derivatives),
wenzelm@60010
  1176
which may produce an unexpected Long_Name.hidden prefix. Note that
wenzelm@60011
  1177
contemporary applications use the strict Name_Space.check (and
wenzelm@60010
  1178
derivatives) instead, which is not affected by the change. Potential
wenzelm@60010
  1179
INCOMPATIBILITY in rare applications of Name_Space.intern.
wenzelm@59951
  1180
wenzelm@60096
  1181
* Subtle change of error semantics of Toplevel.proof_of: regular user
wenzelm@60096
  1182
ERROR instead of internal Toplevel.UNDEF.
wenzelm@60096
  1183
wenzelm@59951
  1184
* Basic combinators map, fold, fold_map, split_list, apply are available
wenzelm@59951
  1185
as parameterized antiquotations, e.g. @{map 4} for lists of quadruples.
wenzelm@59951
  1186
wenzelm@59951
  1187
* Renamed "pairself" to "apply2", in accordance to @{apply 2}.
wenzelm@59951
  1188
INCOMPATIBILITY.
wenzelm@59951
  1189
wenzelm@59951
  1190
* Former combinators NAMED_CRITICAL and CRITICAL for central critical
wenzelm@59951
  1191
sections have been discontinued, in favour of the more elementary
wenzelm@59951
  1192
Multithreading.synchronized and its high-level derivative
wenzelm@59951
  1193
Synchronized.var (which is usually sufficient in applications). Subtle
wenzelm@59951
  1194
INCOMPATIBILITY: synchronized access needs to be atomic and cannot be
wenzelm@59951
  1195
nested.
wenzelm@59951
  1196
wenzelm@60010
  1197
* Synchronized.value (ML) is actually synchronized (as in Scala): subtle
wenzelm@60010
  1198
change of semantics with minimal potential for INCOMPATIBILITY.
wenzelm@59899
  1199
wenzelm@59621
  1200
* The main operations to certify logical entities are Thm.ctyp_of and
wenzelm@59621
  1201
Thm.cterm_of with a local context; old-style global theory variants are
wenzelm@59621
  1202
available as Thm.global_ctyp_of and Thm.global_cterm_of.
wenzelm@59621
  1203
INCOMPATIBILITY.
wenzelm@59621
  1204
wenzelm@59582
  1205
* Elementary operations in module Thm are no longer pervasive.
wenzelm@59582
  1206
INCOMPATIBILITY, need to use qualified Thm.prop_of, Thm.cterm_of,

  1207
Thm.term_of etc.
wenzelm@59582
  1208
wenzelm@58963
  1209
* Proper context for various elementary tactics: assume_tac,
wenzelm@59498
  1210
resolve_tac, eresolve_tac, dresolve_tac, forward_tac, match_tac,
wenzelm@59498
  1211
compose_tac, Splitter.split_tac etc. INCOMPATIBILITY.
wenzelm@58956
  1212
blanchet@58066
  1213
* Tactical PARALLEL_ALLGOALS is the most common way to refer to
blanchet@58066
  1214
PARALLEL_GOALS.
blanchet@58066
  1215
wenzelm@59564
  1216
* Goal.prove_multi is superseded by the fully general Goal.prove_common,
wenzelm@59564
  1217
which also allows to specify a fork priority.
wenzelm@59564
  1218
wenzelm@59936
  1219
* Antiquotation @{command_spec "COMMAND"} is superseded by
wenzelm@59936
  1220
@{command_keyword COMMAND} (usually without quotes and with PIDE
wenzelm@59936
  1221
markup). Minor INCOMPATIBILITY.
wenzelm@59936
  1222
wenzelm@60010
  1223
* Cartouches within ML sources are turned into values of type

cartouches instead of old-style {* verbatim *} or `alt_string` tokens.
wenzelm@59951
  1231
wenzelm@60108

* The Isabelle tool "build" provides new options -X, -k, -x.
wenzelm@59951
  1233
wenzelm@59951
  1234
* Discontinued old-fashioned "codegen" tool. Code generation can always
wenzelm@59951
  1235
be externally triggered using an appropriate ROOT file plus a
wenzelm@59951
  1236
corresponding theory. Parametrization is possible using environment

wenzelm@59200
  1242
wenzelm@59201

  1255
*** General ***
wenzelm@54702
  1256
wenzelm@57452
  1257
* Support for official Standard ML within the Isabelle context.
wenzelm@57452
  1258
Command 'SML_file' reads and evaluates the given Standard ML file.
wenzelm@57452
  1259
Toplevel bindings are stored within the theory context; the initial
wenzelm@57452
  1260
environment is restricted to the Standard ML implementation of
wenzelm@57452
  1261
Poly/ML, without the add-ons of Isabelle/ML.  Commands 'SML_import'
wenzelm@57452
  1262
and 'SML_export' allow to exchange toplevel bindings between the two
wenzelm@57452
  1263
separate environments.  See also ~~/src/Tools/SML/Examples.thy for
wenzelm@57452
  1264
some examples.
wenzelm@56499
  1265
wenzelm@57504
  1266
* Standard tactics and proof methods such as "clarsimp", "auto" and
wenzelm@57504
  1267
"safe" now preserve equality hypotheses "x = expr" where x is a free
wenzelm@57504
  1268
variable.  Locale assumptions and chained facts containing "x"
wenzelm@57504
  1269
continue to be useful.  The new method "hypsubst_thin" and the
wenzelm@57504
  1270
configuration option "hypsubst_thin" (within the attribute name space)
wenzelm@57504
  1271
restore the previous behavior.  INCOMPATIBILITY, especially where
wenzelm@57504
  1272
induction is done after these methods or when the names of free and
wenzelm@57504
  1273
bound variables clash.  As first approximation, old proofs may be
wenzelm@57504
  1274
repaired by "using [[hypsubst_thin = true]]" in the critical spot.
wenzelm@57504
  1275
wenzelm@56232
  1276
* More static checking of proof methods, which allows the system to
wenzelm@56232
  1277
form a closure over the concrete syntax.  Method arguments should be
wenzelm@56232
  1278
processed in the original proof context as far as possible, before
wenzelm@56232
  1279
operating on the goal state.  In any case, the standard discipline for
wenzelm@56232
  1280
subgoal-addressing needs to be observed: no subgoals or a subgoal
wenzelm@56232
  1281
number that is out of range produces an empty result sequence, not an
wenzelm@56232
  1282
exception.  Potential INCOMPATIBILITY for non-conformant tactical
wenzelm@56232
  1283
proof tools.
wenzelm@56232
  1284
wenzelm@57452
  1285
* Lexical syntax (inner and outer) supports text cartouches with
wenzelm@57452
  1286
arbitrary nesting, and without escapes of quotes etc.  The Prover IDE
wenzelm@57452
  1287
supports input via ` (backquote).
wenzelm@57452
  1288
wenzelm@57452
  1289
* The outer syntax categories "text" (for formal comments and document
wenzelm@57452
  1290
markup commands) and "altstring" (for literal fact references) allow
wenzelm@57452
  1291
cartouches as well, in addition to the traditional mix of quotations.
wenzelm@57452
  1292
wenzelm@57452
  1293
* Syntax of document antiquotation @{rail} now uses \<newline> instead
wenzelm@57452
  1294
of "\\", to avoid the optical illusion of escaped backslash within
wenzelm@57491
  1295
string token.  General renovation of its syntax using text cartouches.
wenzelm@57452
  1296
Minor INCOMPATIBILITY.
wenzelm@57452
  1297
wenzelm@57452
  1298
* Discontinued legacy_isub_isup, which was a temporary workaround for
wenzelm@57452
  1299
Isabelle/ML in Isabelle2013-1.  The prover process no longer accepts
wenzelm@57452
  1300
old identifier syntax with \<^isub> or \<^isup>.  Potential
wenzelm@57452
  1301
INCOMPATIBILITY.
wenzelm@57452
  1302
wenzelm@57452
  1303
* Document antiquotation @{url} produces markup for the given URL,
wenzelm@57452
  1304
which results in an active hyperlink within the text.
wenzelm@57452
  1305
wenzelm@57452
  1306
* Document antiquotation @{file_unchecked} is like @{file}, but does
wenzelm@57452
  1307
not check existence within the file-system.
wenzelm@57452
  1308
wenzelm@57452

Open text buffers take precedence over copies within the file-system.

wenzelm@57423
  1329
templates, completion language context, name-space completion,
wenzelm@57423
  1330
file-name completion, spell-checker completion.
wenzelm@57423
  1331
wenzelm@57423
  1332
* Refined GUI popup for completion: more robust key/mouse event
wenzelm@57423
  1333
handling and propagation to enclosing text area -- avoid loosing
wenzelm@57423
  1334
keystrokes with slow / remote graphics displays.
wenzelm@57423
  1335
wenzelm@57833
  1336
* Completion popup supports both ENTER and TAB (default) to select an
wenzelm@57833
  1337
item, depending on Isabelle options.
wenzelm@57833
  1338
wenzelm@57423
  1339
* Refined insertion of completion items wrt. jEdit text: multiple
wenzelm@57423
  1340
selections, rectangular selections, rectangular selection as "tall
wenzelm@57423
  1341
caret".
wenzelm@56342
  1342
wenzelm@56580
  1343
* Integrated spell-checker for document text, comments etc. with

wenzelm@56879
  1346
* More general "Query" panel supersedes "Find" panel, with GUI access
wenzelm@56879
  1347
to commands 'find_theorems' and 'find_consts', as well as print
wenzelm@56879
  1348
operations for the context.  Minor incompatibility in keyboard
wenzelm@56879
  1349
shortcuts etc.: replace action isabelle-find by isabelle-query.
wenzelm@56761
  1350
wenzelm@56901
  1351
* Search field for all output panels ("Output", "Query", "Info" etc.)
wenzelm@56901
  1352
to highlight text via regular expression.
wenzelm@56901
  1353
wenzelm@54881
  1354
* Option "jedit_print_mode" (see also "Plugin Options / Isabelle /
wenzelm@54881
  1355
General") allows to specify additional print modes for the prover
wenzelm@54881
  1356
process, without requiring old-fashioned command-line invocation of
wenzelm@54881
  1357
"isabelle jedit -m MODE".
wenzelm@54881
  1358
wenzelm@56505
  1359
* More support for remote files (e.g. http) using standard Java
wenzelm@56505
  1360
networking operations instead of jEdit virtual file-systems.
wenzelm@56505
  1361
wenzelm@57822
  1362
* Empty editors buffers that are no longer required (e.g.\ via theory
wenzelm@57822
  1363
imports) are automatically removed from the document model.
wenzelm@57822
  1364
wenzelm@57869
  1365
* Improved monitor panel.
wenzelm@57869
  1366
wenzelm@56838
  1367
* Improved Console/Scala plugin: more uniform scala.Console output,
wenzelm@56838
  1368
more robust treatment of threads and interrupts.
wenzelm@56838
  1369
wenzelm@56939
  1370
* Improved management of dockable windows: clarified keyboard focus
wenzelm@56939
  1371
and window placement wrt. main editor view; optional menu item to
wenzelm@56939
  1372
"Detach" a copy where this makes sense.
wenzelm@56939
  1373
wenzelm@57452
  1374
* New Simplifier Trace panel provides an interactive view of the
wenzelm@57594
  1375
simplification process, enabled by the "simp_trace_new" attribute
wenzelm@57452
  1376
within the context.

wenzelm@57504
  1381
* Low-level type-class commands 'classes', 'classrel', 'arities' have
wenzelm@57504
  1382
been discontinued to avoid the danger of non-trivial axiomatization
wenzelm@57504
  1383
that is not immediately visible.  INCOMPATIBILITY, use regular
wenzelm@57504
  1384
'instance' command with proof.  The required OFCLASS(...) theorem
wenzelm@57504
  1385
might be postulated via 'axiomatization' beforehand, or the proof
wenzelm@57504
  1386
finished trivially if the underlying class definition is made vacuous
wenzelm@57504
  1387
(without any assumptions).  See also Isabelle/ML operations

* Basic constants of Pure use more conventional names and are always
wenzelm@56245
  1392
qualified.  Rare INCOMPATIBILITY, but with potentially serious
wenzelm@56245
  1393
consequences, notably for tools in Isabelle/ML.  The following
wenzelm@56245
  1394
renaming needs to be applied:
wenzelm@56245
  1395
wenzelm@56245
  1396
  ==             ~>  Pure.eq
wenzelm@56245
  1397
  ==>            ~>  Pure.imp
wenzelm@56245
  1398
  all            ~>  Pure.all
wenzelm@56245
  1399
  TYPE           ~>  Pure.type
wenzelm@56245
  1400
  dummy_pattern  ~>  Pure.dummy_pattern
wenzelm@56245
  1401
wenzelm@56245
  1402
Systematic porting works by using the following theory setup on a
wenzelm@56245
  1403
*previous* Isabelle version to introduce the new name accesses for the
wenzelm@56245
  1404
old constants:
wenzelm@56245
  1405
wenzelm@56245
  1406
setup {*
wenzelm@56245
  1407
  fn thy => thy
wenzelm@56245
  1408
    |> Sign.root_path
wenzelm@56245
  1409
    |> Sign.const_alias (Binding.qualify true "Pure" @{binding eq}) "=="
wenzelm@56245
  1410
    |> Sign.const_alias (Binding.qualify true "Pure" @{binding imp}) "==>"
wenzelm@56245
  1411
    |> Sign.const_alias (Binding.qualify true "Pure" @{binding all}) "all"
wenzelm@56245
  1412
    |> Sign.restore_naming thy
wenzelm@56245
  1413
*}
wenzelm@56245
  1414
wenzelm@56245
  1415
Thus ML antiquotations like @{const_name Pure.eq} may be used already.
wenzelm@56245
  1416
Later the application is moved to the current Isabelle version, and
wenzelm@56245
  1417
the auxiliary aliases are deleted.
wenzelm@56245
  1418
wenzelm@55143
  1419
* Attributes "where" and "of" allow an optional context of local
wenzelm@55143
  1420
variables ('for' declaration): these variables become schematic in the
wenzelm@55143
  1421
instantiated theorem.
wenzelm@55143
  1422
wenzelm@55152
  1423
* Obsolete attribute "standard" has been discontinued (legacy since
wenzelm@55152
  1424
Isabelle2012).  Potential INCOMPATIBILITY, use explicit 'for' context
wenzelm@55152
  1425
where instantiations with schematic variables are intended (for
wenzelm@55152
  1426
declaration commands like 'lemmas' or attributes like "of").  The
wenzelm@55152
  1427
following temporary definition may help to port old applications:
wenzelm@55152
  1428
wenzelm@55152
  1429
  attribute_setup standard =
wenzelm@55152
  1430
    "Scan.succeed (Thm.rule_attribute (K Drule.export_without_context))"
wenzelm@55152
  1431
wenzelm@55001
  1432
* More thorough check of proof context for goal statements and
wenzelm@55006
  1433
attributed fact expressions (concerning background theory, declared
wenzelm@55006
  1434
hyps).  Potential INCOMPATIBILITY, tools need to observe standard
wenzelm@55006
  1435
context discipline.  See also Assumption.add_assumes and the more
wenzelm@55006
  1436
primitive Thm.assume_hyps.
wenzelm@55001
  1437
wenzelm@55108
  1438
* Inner syntax token language allows regular quoted strings "..."
wenzelm@55108
  1439
(only makes sense in practice, if outer syntax is delimited
wenzelm@57452
  1440
differently, e.g. via cartouches).
wenzelm@57452
  1441
wenzelm@57504
  1442
* Command 'print_term_bindings' supersedes 'print_binds' for clarity,
wenzelm@57504
  1443
but the latter is retained some time as Proof General legacy.
wenzelm@57504
  1444
wenzelm@57452
  1445
* Code generator preprocessor: explicit control of simp tracing on a
wenzelm@57452

INCOMPATIBILITY.
wenzelm@57504
  1459
wenzelm@57504
  1460

ML.  Minor INCOMPATIBILITY.
wenzelm@57452
  1474
wenzelm@57504

* Renamed command 'enriched_type' to 'functor'. INCOMPATIBILITY.
wenzelm@57504
  1476
wenzelm@57504
  1477
* The symbol "\<newline>" may be used within char or string literals
wenzelm@57504
  1478
to represent (Char Nibble0 NibbleA), i.e. ASCII newline.
wenzelm@57504
  1479
wenzelm@57504

wenzelm@57452
  1482
* Simplifier: Enhanced solver of preconditions of rewrite rules can
wenzelm@57452
  1483
now deal with conjunctions.  For help with converting proofs, the old
wenzelm@57452
  1484
behaviour of the simplifier can be restored like this: declare/using
wenzelm@57452
  1485
[[simp_legacy_precond]].  This configuration option will disappear
wenzelm@57452
  1486
again in the future.  INCOMPATIBILITY.
nipkow@56073
  1487
wenzelm@55139
  1488
* Simproc "finite_Collect" is no longer enabled by default, due to
wenzelm@55139
  1489
spurious crashes and other surprises.  Potential INCOMPATIBILITY.
wenzelm@55139
  1490
wenzelm@57452
  1491
* Moved new (co)datatype package and its dependencies from session
wenzelm@57452

  1563
  - The generated constants "xxx_case", "xxx_rec", and "xxx_size" have

* New internal SAT solver "cdclite" that produces models and proof
wenzelm@57508
  1641
traces.  This solver replaces the internal SAT solvers "enumerate" and
wenzelm@57508
  1642
"dpll".  Applications that explicitly used one of these two SAT
wenzelm@57508
  1643
solvers should use "cdclite" instead. In addition, "cdclite" is now
wenzelm@57508
  1644
the default SAT solver for the "sat" and "satx" proof methods and
wenzelm@57508
  1645
corresponding tactics; the old default can be restored using "declare
wenzelm@57508

[[sat_solver = zchaff_with_proofs]]".  Minor INCOMPATIBILITY.

* SMT module: A new version of the SMT module, temporarily called
wenzelm@57508
  1649
"SMT2", uses SMT-LIB 2 and supports recent versions of Z3 (e.g.,
wenzelm@57508
  1650
4.3). The new proof method is called "smt2". CVC3 and CVC4 are also
wenzelm@57508
  1651
supported as oracles. Yices is no longer supported, because no version
wenzelm@57508
  1652
of the solver can handle both SMT-LIB 2 and quantifiers.
wenzelm@57508
  1653
wenzelm@57508

blanchet@57532
  1662
    . New SML-based learning algorithms eliminate the dependency on
wenzelm@57508
  1663
      Python and increase performance and reliability.
wenzelm@57508
  1664
    . MaSh and MeSh are now used by default together with the
wenzelm@57508
  1665
      traditional MePo (Meng-Paulson) relevance filter. To disable
wenzelm@57508

      MaSh, set the "MaSh" system option in Isabelle/jEdit Plugin
wenzelm@57508

wenzelm@57508
  1683

  - Consolidated theorem names containing INFI and SUPR: have INF and
wenzelm@57508
  1695
    SUP instead uniformly.
wenzelm@57508
  1696
  - More aggressive normalization of expressions involving INF and Inf
wenzelm@57508
  1697
    or SUP and Sup.
wenzelm@57508
  1698
  - INF_image and SUP_image do not unfold composition.
wenzelm@57508
  1699
  - Dropped facts INF_comp, SUP_comp.
wenzelm@57508
  1700
  - Default congruence rules strong_INF_cong and strong_SUP_cong, with
wenzelm@57508

* The signature and semantics of Document.Snapshot.cumulate_markup /
wenzelm@55622
  2234
select_markup have been clarified.  Markup is now traversed in the
wenzelm@55622
  2235
order of reports given by the prover: later markup is usually more
wenzelm@55622
  2236
specific and may override results accumulated so far.  The elements
wenzelm@55622
  2237
guard is mandatory and checked precisely.  Subtle INCOMPATIBILITY.

wenzelm@54449
  2244
wenzelm@57504
  2245
* Subtle change of semantics of Thm.eq_thm: theory stamps are not
wenzelm@57504
  2246
compared (according to Thm.thm_ord), but assumed to be covered by the
wenzelm@57504
  2247
current background theory.  Thus equivalent data produced in different
wenzelm@57504
  2248
branches of the theory graph usually coincides (e.g. relevant for
wenzelm@57504
  2249
theory merge).  Note that the softer Thm.eq_thm_prop is often more
wenzelm@57504
  2250
appropriate than Thm.eq_thm.
wenzelm@57504
  2251
wenzelm@57504
  2252
* Proper context for basic Simplifier operations: rewrite_rule,
wenzelm@57504
  2253
rewrite_goals_rule, rewrite_goals_tac etc. INCOMPATIBILITY, need to
wenzelm@57504
  2254
pass runtime Proof.context (and ensure that the simplified entity
wenzelm@57504
  2255
actually belongs to it).
wenzelm@57504
  2256
wenzelm@57504
  2257
* Proper context discipline for read_instantiate and instantiate_tac:
wenzelm@57504
  2258
variables that are meant to become schematic need to be given as
wenzelm@57504
  2259
fixed, and are generalized by the explicit context of local variables.
wenzelm@57504
  2260
This corresponds to Isar attributes "where" and "of" with 'for'
wenzelm@57504
  2261
declaration.  INCOMPATIBILITY, also due to potential change of indices
wenzelm@57504
  2262
of schematic variables.
wenzelm@57504
  2263
wenzelm@56303
  2264
* Moved ML_Compiler.exn_trace and other operations on exceptions to
wenzelm@56303
  2265
structure Runtime.  Minor INCOMPATIBILITY.
wenzelm@56303
  2266
wenzelm@56279
  2267
* Discontinued old Toplevel.debug in favour of system option
wenzelm@57452
  2268
"ML_exception_trace", which may be also declared within the context
wenzelm@57452
  2269
via "declare [[ML_exception_trace = true]]".  Minor INCOMPATIBILITY.
wenzelm@56279
  2270
wenzelm@56281
  2271
* Renamed configuration option "ML_trace" to "ML_source_trace". Minor
wenzelm@56281
  2272
INCOMPATIBILITY.
wenzelm@56281
  2273
wenzelm@56281
  2274
* Configuration option "ML_print_depth" controls the pretty-printing
wenzelm@56281
  2275
depth of the ML compiler within the context.  The old print_depth in
wenzelm@56285
  2276
ML is still available as default_print_depth, but rarely used.  Minor
wenzelm@56285
  2277
INCOMPATIBILITY.
wenzelm@56279
  2278
wenzelm@54449
  2279
* Toplevel function "use" refers to raw ML bootstrap environment,
wenzelm@54449
  2280
without Isar context nor antiquotations.  Potential INCOMPATIBILITY.
wenzelm@54449
  2281
Note that 'ML_file' is the canonical command to load ML files into the
wenzelm@54449
  2282
formal context.
wenzelm@54449
  2283
wenzelm@56205
  2284
* Simplified programming interface to define ML antiquotations, see
wenzelm@56205
  2285
structure ML_Antiquotation.  Minor INCOMPATIBILITY.
wenzelm@56069
  2286
wenzelm@56071
  2287
* ML antiquotation @{here} refers to its source position, which is
wenzelm@56071
  2288
occasionally useful for experimentation and diagnostic purposes.
wenzelm@56071
  2289
wenzelm@56135
  2290
* ML antiquotation @{path} produces a Path.T value, similarly to
wenzelm@56135
  2291
Path.explode, but with compile-time check against the file-system and
wenzelm@56135
  2292
some PIDE markup.  Note that unlike theory source, ML does not have a
wenzelm@56135
  2293
well-defined master directory, so an absolute symbolic path
wenzelm@56135
  2294
specification is usually required, e.g. "~~/src/HOL".
wenzelm@56135
  2295
wenzelm@56399
  2296
* ML antiquotation @{print} inlines a function to print an arbitrary
wenzelm@56399
  2297
ML value, which is occasionally useful for diagnostic or demonstration
wenzelm@56399
  2298
purposes.

  2303
* Proof General with its traditional helper scripts is now an optional
wenzelm@57504
  2304
Isabelle component, e.g. see ProofGeneral-4.2-2 from the Isabelle
wenzelm@57504
  2305
component repository http://isabelle.in.tum.de/components/.  Note that
wenzelm@57504
  2306
the "system" manual provides general explanations about add-on
wenzelm@57504
  2307
components, especially those that are not bundled with the release.
wenzelm@57443
  2308
wenzelm@56439
  2309
* The raw Isabelle process executable has been renamed from
wenzelm@56439
  2310
"isabelle-process" to "isabelle_process", which conforms to common
wenzelm@56439
  2311
shell naming conventions, and allows to define a shell function within
wenzelm@56439
  2312
the Isabelle environment to avoid dynamic path lookup.  Rare
wenzelm@57504
  2313
incompatibility for old tools that do not use the ISABELLE_PROCESS
wenzelm@57504
  2314
settings variable.
wenzelm@56439
  2315
wenzelm@57439
  2316
* Former "isabelle tty" has been superseded by "isabelle console",
wenzelm@57439
  2317
with implicit build like "isabelle jedit", and without the mostly
wenzelm@57439
  2318
obsolete Isar TTY loop.
wenzelm@57439
  2319
wenzelm@57452
  2320
* Simplified "isabelle display" tool.  Settings variables DVI_VIEWER
wenzelm@57452
  2321
and PDF_VIEWER now refer to the actual programs, not shell
wenzelm@57452
  2322
command-lines.  Discontinued option -c: invocation may be asynchronous
wenzelm@57452
  2323
via desktop environment, without any special precautions.  Potential
wenzelm@57452
  2324
INCOMPATIBILITY with ambitious private settings.
wenzelm@57452
  2325
wenzelm@57413
  2326
* Removed obsolete "isabelle unsymbolize".  Note that the usual format
wenzelm@57413
  2327
for email communication is the Unicode rendering of Isabelle symbols,
wenzelm@57413
  2328
as produced by Isabelle/jEdit, for example.
wenzelm@57413
  2329
wenzelm@57452
  2330
* Removed obsolete tool "wwwfind". Similar functionality may be
wenzelm@57452
  2331
integrated into Isabelle/jEdit eventually.
wenzelm@57452
  2332
wenzelm@57452
  2333
* Improved 'display_drafts' concerning desktop integration and
wenzelm@57452
  2334
repeated invocation in PIDE front-end: re-use single file
wenzelm@57452
  2335
$ISABELLE_HOME_USER/tmp/drafts.pdf and corresponding views.
wenzelm@57084
  2336
wenzelm@57452
  2337
* Session ROOT specifications require explicit 'document_files' for
wenzelm@57452
  2338
robust dependencies on LaTeX sources.  Only these explicitly given
wenzelm@57452
  2339
files are copied to the document output directory, before document
wenzelm@57452
  2340
processing is started.
wenzelm@57452
  2341
wenzelm@57504
  2342
* Windows: support for regular TeX installation (e.g. MiKTeX) instead

wenzelm@54639
  2351
wenzelm@54639
  2352
* More robust editing of running commands with internal forks,
wenzelm@54639
  2353
e.g. non-terminating 'by' steps.
wenzelm@54639
  2354
wenzelm@54641
  2355
* More relaxed Sledgehammer panel: avoid repeated application of query
wenzelm@54641
  2356
after edits surrounding the command location.
wenzelm@54641
  2357
wenzelm@54648
  2358
* More status information about commands that are interrupted
wenzelm@54648
  2359
accidentally (via physical event or Poly/ML runtime system signal,
wenzelm@54648
  2360
e.g. out-of-memory).

*** System ***
wenzelm@54653
  2364
wenzelm@54653
  2365
* More robust termination of external processes managed by
wenzelm@54664
  2366
Isabelle/ML: support cancellation of tasks within the range of
wenzelm@54664
  2367
milliseconds, as required for PIDE document editing with automatically
wenzelm@54664
  2368
tried tools (e.g. Sledgehammer).
wenzelm@54653
  2369
wenzelm@54648
  2370
* Reactivated Isabelle/Scala kill command for external processes on
wenzelm@54648
  2371
Mac OS X, which was accidentally broken in Isabelle2013-1 due to a
wenzelm@54648
  2372
workaround for some Debian/Ubuntu Linux versions from 2013.

wenzelm@51293
  2379
*** General ***
wenzelm@51293
  2380
wenzelm@53971
  2381
* Discontinued obsolete 'uses' within theory header.  Note that
wenzelm@53971
  2382
commands like 'ML_file' work without separate declaration of file
wenzelm@53971
  2383
dependencies.  Minor INCOMPATIBILITY.
wenzelm@53971
  2384
wenzelm@53971
  2385
* Discontinued redundant 'use' command, which was superseded by
wenzelm@53971
  2386
'ML_file' in Isabelle2013.  Minor INCOMPATIBILITY.
wenzelm@53971
  2387
wenzelm@53016
  2388
* Simplified subscripts within identifiers, using plain \<^sub>
wenzelm@53016
  2389
instead of the second copy \<^isub> and \<^isup>.  Superscripts are
wenzelm@53016
  2390
only for literal tokens within notation; explicit mixfix annotations
wenzelm@53016
  2391
for consts or fixed variables may be used as fall-back for unusual
wenzelm@53016
  2392
names.  Obsolete \<twosuperior> has been expanded to \<^sup>2 in
wenzelm@53016
  2393
Isabelle/HOL.  INCOMPATIBILITY, use "isabelle update_sub_sup" to
wenzelm@53016
  2394
standardize symbols as a starting point for further manual cleanup.
wenzelm@53016
  2395
The ML reference variable "legacy_isub_isup" may be set as temporary
wenzelm@53016
  2396
workaround, to make the prover accept a subset of the old identifier
wenzelm@53016
  2397
syntax.
wenzelm@53016
  2398
wenzelm@53021
  2399
* Document antiquotations: term style "isub" has been renamed to
wenzelm@53021
  2400
"sub".  Minor INCOMPATIBILITY.
wenzelm@53021
  2401
wenzelm@52487
  2402
* Uniform management of "quick_and_dirty" as system option (see also
wenzelm@52487
  2403
"isabelle options"), configuration option within the context (see also
wenzelm@52487
  2404
Config.get in Isabelle/ML), and attribute in Isabelle/Isar.  Minor
wenzelm@52487
  2405
INCOMPATIBILITY, need to use more official Isabelle means to access
wenzelm@52487
  2406
quick_and_dirty, instead of historical poking into mutable reference.
wenzelm@52059
  2407
wenzelm@52060
  2408
* Renamed command 'print_configs' to 'print_options'.  Minor
wenzelm@52060
  2409
INCOMPATIBILITY.
wenzelm@52060
  2410
wenzelm@52430
  2411
* Proper diagnostic command 'print_state'.  Old 'pr' (with its
wenzelm@52430
  2412
implicit change of some global references) is retained for now as
wenzelm@52430
  2413
control command, e.g. for ProofGeneral 3.7.x.
wenzelm@52430
  2414
wenzelm@52549
  2415
* Discontinued 'print_drafts' command with its old-fashioned PS output
wenzelm@52549
  2416
and Unix command-line print spooling.  Minor INCOMPATIBILITY: use
wenzelm@52549
  2417
'display_drafts' instead and print via the regular document viewer.
wenzelm@52549
  2418
wenzelm@53971
  2419
* Updated and extended "isar-ref" and "implementation" manual,
wenzelm@53971
  2420
eliminated old "ref" manual.

*** Prover IDE -- Isabelle/Scala/jEdit ***
wenzelm@51533
  2424
wenzelm@53971
  2425
* New manual "jedit" for Isabelle/jEdit, see isabelle doc or
wenzelm@53852
  2426
Documentation panel.
wenzelm@53852
  2427
wenzelm@53971
  2428
* Dockable window "Documentation" provides access to Isabelle
wenzelm@53971
  2429
documentation.
wenzelm@52646
  2430
wenzelm@52949
  2431
* Dockable window "Find" provides query operations for formal entities
wenzelm@52949
  2432
(GUI front-end to 'find_theorems' command).
wenzelm@52949
  2433
wenzelm@53050
  2434
* Dockable window "Sledgehammer" manages asynchronous / parallel
wenzelm@53050
  2435
sledgehammer runs over existing document sources, independently of
wenzelm@53050
  2436
normal editing and checking process.
wenzelm@53050
  2437
wenzelm@51533
  2438
* Dockable window "Timing" provides an overview of relevant command
wenzelm@54332
  2439
timing information, depending on option jedit_timing_threshold.  The
wenzelm@54332
  2440
same timing information is shown in the extended tooltip of the
wenzelm@54332
  2441
command keyword, when hovering the mouse over it while the CONTROL or
wenzelm@54332
  2442
COMMAND modifier is pressed.
wenzelm@51533
  2443
wenzelm@53971
  2444
* Improved dockable window "Theories": Continuous checking of proof
wenzelm@53971
  2445
document (visible and required parts) may be controlled explicitly,
wenzelm@53971
  2446
using check box or shortcut "C+e ENTER".  Individual theory nodes may
wenzelm@53971
  2447
be marked explicitly as required and checked in full, using check box
wenzelm@53971
  2448
or shortcut "C+e SPACE".
wenzelm@53971
  2449
wenzelm@54305
  2450
* Improved completion mechanism, which is now managed by the
wenzelm@54305
  2451
Isabelle/jEdit plugin instead of SideKick.  Refined table of Isabelle
wenzelm@54305
  2452
symbol abbreviations (see $ISABELLE_HOME/etc/symbols).
wenzelm@54305
  2453
wenzelm@54319
  2454
* Standard jEdit keyboard shortcut C+b complete-word is remapped to
wenzelm@54319
  2455
isabelle.complete for explicit completion in Isabelle sources.
wenzelm@54319
  2456
INCOMPATIBILITY wrt. jEdit defaults, may have to invent new shortcuts
wenzelm@54319
  2457
to resolve conflict.
wenzelm@54319
  2458
wenzelm@54305
  2459
* Improved support of various "minor modes" for Isabelle NEWS,
wenzelm@54305
  2460
options, session ROOT etc., with completion and SideKick tree view.
wenzelm@54305
  2461
wenzelm@53971
  2462
* Strictly monotonic document update, without premature cancellation of
wenzelm@53971
  2463
running transactions that are still needed: avoid reset/restart of
wenzelm@53971
  2464
such command executions while editing.
wenzelm@53271
  2465
wenzelm@53971
  2466
* Support for asynchronous print functions, as overlay to existing
wenzelm@53971
  2467
document content.
wenzelm@53971
  2468
wenzelm@53971
  2469
* Support for automatic tools in HOL, which try to prove or disprove
wenzelm@53971
  2470
toplevel theorem statements.
wenzelm@53971
  2471
wenzelm@53971
  2472
* Action isabelle.reset-font-size resets main text area font size
wenzelm@54365
  2473
according to Isabelle/Scala plugin option "jedit_font_reset_size" (see
wenzelm@54365
  2474
also "Plugin Options / Isabelle / General").  It can be bound to some
wenzelm@54365
  2475
keyboard shortcut by the user (e.g. C+0 and/or C+NUMPAD0).
wenzelm@53971
  2476
wenzelm@53971
  2477
* File specifications in jEdit (e.g. file browser) may refer to
wenzelm@54351
  2478
$ISABELLE_HOME and $ISABELLE_HOME_USER on all platforms.  Discontinued
wenzelm@54351
  2479
obsolete $ISABELLE_HOME_WINDOWS variable.
wenzelm@53971
  2480
wenzelm@53971
  2481
* Improved support for Linux look-and-feel "GTK+", see also "Utilities
wenzelm@53971
  2482
/ Global Options / Appearance".
wenzelm@53971
  2483
wenzelm@53971
  2484
* Improved support of native Mac OS X functionality via "MacOSX"
wenzelm@53971
  2485
plugin, which is now enabled by default.

*** Pure ***
wenzelm@51313
  2489
ballarin@54049
  2490
* Commands 'interpretation' and 'sublocale' are now target-sensitive.
ballarin@54049
  2491
In particular, 'interpretation' allows for non-persistent
ballarin@54049
  2492
interpretation within "context ... begin ... end" blocks offering a
ballarin@54049
  2493
light-weight alternative to 'sublocale'.  See "isar-ref" manual for
ballarin@54049
  2494
details.
haftmann@51747
  2495
ballarin@51565
  2496
* Improved locales diagnostic command 'print_dependencies'.
ballarin@51565
  2497
wenzelm@51313
  2498
* Discontinued obsolete 'axioms' command, which has been marked as
wenzelm@51313
  2499
legacy since Isabelle2009-2.  INCOMPATIBILITY, use 'axiomatization'
wenzelm@51313
  2500
instead, while observing its uniform scope for polymorphism.
wenzelm@51313
  2501
wenzelm@51316
  2502
* Discontinued empty name bindings in 'axiomatization'.
wenzelm@51316
  2503
INCOMPATIBILITY.
wenzelm@51316
  2504
wenzelm@53971
  2505
* System option "proofs" has been discontinued.  Instead the global
wenzelm@53971
  2506
state of Proofterm.proofs is persistently compiled into logic images
wenzelm@53971
  2507
as required, notably HOL-Proofs.  Users no longer need to change
wenzelm@53971
  2508
Proofterm.proofs dynamically.  Minor INCOMPATIBILITY.
wenzelm@53971
  2509
wenzelm@53971
  2510
* Syntax translation functions (print_translation etc.) always depend
wenzelm@53971
  2511
on Proof.context.  Discontinued former "(advanced)" option -- this is
wenzelm@53971
  2512
now the default.  Minor INCOMPATIBILITY.
wenzelm@53971
  2513
wenzelm@53971
  2514
* Former global reference trace_unify_fail is now available as
wenzelm@53971
  2515
configuration option "unify_trace_failure" (global context only).
wenzelm@53971
  2516
wenzelm@52463
  2517
* SELECT_GOAL now retains the syntactic context of the overall goal
wenzelm@52463
  2518
state (schematic variables etc.).  Potential INCOMPATIBILITY in rare
wenzelm@52463
  2519
situations.

hoelzl@51002
  2523
wenzelm@54032
  2524
* Stronger precedence of syntax for big intersection and union on
wenzelm@54032
  2525
sets, in accordance with corresponding lattice operations.
wenzelm@54032
  2526
INCOMPATIBILITY.
wenzelm@54032
  2527
wenzelm@54032
  2528
* Notation "{p:A. P}" now allows tuple patterns as well.
wenzelm@54032
  2529
wenzelm@54032
  2530
* Nested case expressions are now translated in a separate check phase
wenzelm@54032
  2531
rather than during parsing. The data for case combinators is separated
wenzelm@54032
  2532
from the datatype package. The declaration attribute
wenzelm@54032
  2533
"case_translation" can be used to register new case combinators:
wenzelm@54032
  2534
wenzelm@54032
  2535
  declare [[case_translation case_combinator constructor1 ... constructorN]]
haftmann@52637
  2536
haftmann@52435
  2537
* Code generator:
wenzelm@53160
  2538
  - 'code_printing' unifies 'code_const' / 'code_type' / 'code_class' /
wenzelm@53160
  2539
    'code_instance'.
wenzelm@53160
  2540
  - 'code_identifier' declares name hints for arbitrary identifiers in
wenzelm@53160
  2541
    generated code, subsuming 'code_modulename'.
wenzelm@53983
  2542
wenzelm@53983
  2543
See the isar-ref manual for syntax diagrams, and the HOL theories for
wenzelm@53983
  2544
examples.
haftmann@52435
  2545
wenzelm@54032
  2546
* Attibute 'code': 'code' now declares concrete and abstract code
wenzelm@54032
  2547
equations uniformly.  Use explicit 'code equation' and 'code abstract'
wenzelm@54032
  2548
to distinguish both when desired.
wenzelm@54032
  2549
wenzelm@54032
  2550
* Discontinued theories Code_Integer and Efficient_Nat by a more
wenzelm@54032
  2551
fine-grain stack of theories Code_Target_Int, Code_Binary_Nat,
wenzelm@54032
  2552
Code_Target_Nat and Code_Target_Numeral.  See the tutorial on code

  2553
generation for details.  INCOMPATIBILITY.
wenzelm@54032
  2554
wenzelm@54032
  2555
* Numeric types are mapped by default to target language numerals:
wenzelm@54032
  2556
natural (replaces former code_numeral) and integer (replaces former
wenzelm@54032
  2557
code_int).  Conversions are available as integer_of_natural /
wenzelm@54032
  2558
natural_of_integer / integer_of_nat / nat_of_integer (in HOL) and
wenzelm@54032
  2559
Code_Numeral.integer_of_natural / Code_Numeral.natural_of_integer (in
wenzelm@54032
  2560
ML).  INCOMPATIBILITY.
wenzelm@54032
  2561
wenzelm@54032
  2562
* Function package: For mutually recursive functions f and g, separate
wenzelm@54032
  2563
cases rules f.cases and g.cases are generated instead of unusable
wenzelm@54032
  2564
f_g.cases which exposed internal sum types. Potential INCOMPATIBILITY,
wenzelm@54032
  2565
in the case that the unusable rule was used nevertheless.
wenzelm@54032
  2566
wenzelm@54032
  2567
* Function package: For each function f, new rules f.elims are
wenzelm@54032
  2568
generated, which eliminate equalities of the form "f x = t".
wenzelm@54032
  2569
wenzelm@54032
  2570
* New command 'fun_cases' derives ad-hoc elimination rules for
wenzelm@54032
  2571
function equations as simplified instances of f.elims, analogous to
wenzelm@54032
  2572
inductive_cases.  See ~~/src/HOL/ex/Fundefs.thy for some examples.

  2573
kuncar@54021
  2574
* Lifting:
kuncar@54021
  2575
  - parametrized correspondence relations are now supported:
wenzelm@54378
  2576
    + parametricity theorems for the raw term can be specified in
kuncar@54021
  2577
      the command lift_definition, which allow us to generate stronger
kuncar@54021
  2578
      transfer rules
kuncar@54021
  2579
    + setup_lifting generates stronger transfer rules if parametric
kuncar@54021
  2580
      correspondence relation can be generated
kuncar@54021
  2581
    + various new properties of the relator must be specified to support
kuncar@54021
  2582
      parametricity
kuncar@54021
  2583
    + parametricity theorem for the Quotient relation can be specified
kuncar@54021
  2584
  - setup_lifting generates domain rules for the Transfer package
kuncar@54021
  2585
  - stronger reflexivity prover of respectfulness theorems for type
kuncar@54021
  2586
    copies
kuncar@54021
  2587
  - ===> and --> are now local. The symbols can be introduced
kuncar@54021
  2588
    by interpreting the locale lifting_syntax (typically in an
kuncar@54021
  2589
    anonymous context)
wenzelm@54378
  2590
  - Lifting/Transfer relevant parts of Library/Quotient_* are now in
kuncar@54021
  2591
    Main. Potential INCOMPATIBILITY
kuncar@54021
  2592
  - new commands for restoring and deleting Lifting/Transfer context:
kuncar@54021
  2593
    lifting_forget, lifting_update
wenzelm@54378
  2594
  - the command print_quotmaps was renamed to print_quot_maps.
kuncar@54021
  2595
    INCOMPATIBILITY
kuncar@54021
  2596
kuncar@54021
  2597
* Transfer:
wenzelm@54378
  2598
  - better support for domains in Transfer: replace Domainp T
kuncar@54021
  2599
    by the actual invariant in a transferred goal
kuncar@54021
  2600
  - transfer rules can have as assumptions other transfer rules
kuncar@54021
  2601
  - Experimental support for transferring from the raw level to the
kuncar@54021
  2602
    abstract level: Transfer.transferred attribute
kuncar@54021
  2603
  - Attribute version of the transfer method: untransferred attribute
kuncar@54021
  2604
haftmann@52286
  2605
* Reification and reflection:
wenzelm@53160
  2606
  - Reification is now directly available in HOL-Main in structure
wenzelm@53160
  2607
    "Reification".
wenzelm@53160
  2608
  - Reflection now handles multiple lists with variables also.
wenzelm@53160
  2609
  - The whole reflection stack has been decomposed into conversions.
haftmann@52286
  2610
INCOMPATIBILITY.
haftmann@52286
  2611
haftmann@51489
  2612
* Revised devices for recursive definitions over finite sets:
haftmann@51489
  2613
  - Only one fundamental fold combinator on finite set remains:
haftmann@51489
  2614
    Finite_Set.fold :: ('a => 'b => 'b) => 'b => 'a set => 'b
haftmann@51489
  2615
    This is now identity on infinite sets.
wenzelm@52745
  2616
  - Locales ("mini packages") for fundamental definitions with
haftmann@51489
  2617
    Finite_Set.fold: folding, folding_idem.
haftmann@51489
  2618
  - Locales comm_monoid_set, semilattice_order_set and
haftmann@51489
  2619
    semilattice_neutr_order_set for big operators on sets.
haftmann@51489
  2620
    See theory Big_Operators for canonical examples.
haftmann@51489
  2621
    Note that foundational constants comm_monoid_set.F and
haftmann@51489
  2622
    semilattice_set.F correspond to former combinators fold_image
haftmann@51489
  2623
    and fold1 respectively.  These are now gone.  You may use
haftmann@51490
  2624
    those foundational constants as substitutes, but it is
wenzelm@53983
  2625
    preferable to interpret the above locales accordingly.
haftmann@51489
  2626
  - Dropped class ab_semigroup_idem_mult (special case of lattice,
haftmann@51489
  2627
    no longer needed in connection with Finite_Set.fold etc.)
haftmann@51489
  2628
  - Fact renames:
haftmann@51489
  2629
      card.union_inter ~> card_Un_Int [symmetric]
haftmann@51489
  2630
      card.union_disjoint ~> card_Un_disjoint
haftmann@51489
  2631
INCOMPATIBILITY.

* Locale hierarchy for abstract orderings and (semi)lattices.
haftmann@51487
  2634
wenzelm@53526
  2635
* Complete_Partial_Order.admissible is defined outside the type class
wenzelm@53526
  2636
ccpo, but with mandatory prefix ccpo. Admissibility theorems lose the
wenzelm@53526
  2637
class predicate assumption or sort constraint when possible.
Andreas@53362
  2638
INCOMPATIBILITY.
Andreas@53362
  2639
wenzelm@53160
  2640
* Introduce type class "conditionally_complete_lattice": Like a
wenzelm@53160
  2641
complete lattice but does not assume the existence of the top and
wenzelm@53160
  2642
bottom elements.  Allows to generalize some lemmas about reals and
wenzelm@53160
  2643
extended reals.  Removed SupInf and replaced it by the instantiation
wenzelm@53160
  2644
of conditionally_complete_lattice for real. Renamed lemmas about
wenzelm@53160
  2645
conditionally-complete lattice from Sup_... to cSup_... and from
wenzelm@53160
  2646
Inf_...  to cInf_... to avoid hidding of similar complete lattice
wenzelm@53160
  2647
lemmas.
wenzelm@53160
  2648
wenzelm@53160
  2649
* Introduce type class linear_continuum as combination of
wenzelm@53160
  2650
conditionally-complete lattices and inner dense linorders which have
wenzelm@53160
  2651
more than one element.  INCOMPATIBILITY.
wenzelm@53160
  2652
wenzelm@53983
  2653
* Introduced type classes order_top and order_bot. The old classes top
wenzelm@53983
  2654
and bot only contain the syntax without assumptions.  INCOMPATIBILITY:
wenzelm@53983
  2655
Rename bot -> order_bot, top -> order_top
lammich@53683
  2656
wenzelm@53160
  2657
* Introduce type classes "no_top" and "no_bot" for orderings without
wenzelm@53160
  2658
top and bottom elements.
hoelzl@51732
  2659
hoelzl@51732
  2660
* Split dense_linorder into inner_dense_order and no_top, no_bot.
hoelzl@51732
  2661
hoelzl@51732
  2662
* Complex_Main: Unify and move various concepts from
wenzelm@53160
  2663
HOL-Multivariate_Analysis to HOL-Complex_Main.
hoelzl@51732
  2664
wenzelm@53983
  2665
 - Introduce type class (lin)order_topology and
wenzelm@53983
  2666
   linear_continuum_topology.  Allows to generalize theorems about
wenzelm@53983
  2667
   limits and order.  Instances are reals and extended reals.
hoelzl@51732
  2668
hoelzl@51732
  2669
 - continuous and continuos_on from Multivariate_Analysis:
wenzelm@53983
  2670
   "continuous" is the continuity of a function at a filter.  "isCont"
wenzelm@53983
  2671
   is now an abbrevitation: "isCont x f == continuous (at _) f".
wenzelm@53983
  2672
wenzelm@53983
  2673
   Generalized continuity lemmas from isCont to continuous on an
wenzelm@53983
  2674
   arbitrary filter.
wenzelm@53983
  2675
wenzelm@53983
  2676
 - compact from Multivariate_Analysis. Use Bolzano's lemma to prove
wenzelm@53983
  2677
   compactness of closed intervals on reals. Continuous functions
wenzelm@53983
  2678
   attain infimum and supremum on compact sets. The inverse of a
wenzelm@53983
  2679
   continuous function is continuous, when the function is continuous
wenzelm@53983
  2680
   on a compact set.
hoelzl@51732
  2681
hoelzl@51732
  2682
 - connected from Multivariate_Analysis. Use it to prove the
hoelzl@51775
  2683
   intermediate value theorem. Show connectedness of intervals on
hoelzl@51775
  2684
   linear_continuum_topology).
hoelzl@51732
  2685
hoelzl@51732
  2686
 - first_countable_topology from Multivariate_Analysis. Is used to
wenzelm@53983
  2687
   show equivalence of properties on the neighbourhood filter of x and
wenzelm@53983
  2688
   on all sequences converging to x.
wenzelm@53983
  2689
wenzelm@53983
  2690
 - FDERIV: Definition of has_derivative moved to Deriv.thy. Moved
wenzelm@53983
  2691
   theorems from Library/FDERIV.thy to Deriv.thy and base the
wenzelm@53983
  2692
   definition of DERIV on FDERIV. Add variants of DERIV and FDERIV
wenzelm@53983
  2693
   which are restricted to sets, i.e. to represent derivatives from
wenzelm@53983
  2694
   left or right.
hoelzl@51732
  2695
hoelzl@51732
  2696
 - Removed the within-filter. It is replaced by the principal filter:
hoelzl@51732
  2697
hoelzl@51732
  2698
     F within X = inf F (principal X)
hoelzl@51732
  2699
hoelzl@51732
  2700
 - Introduce "at x within U" as a single constant, "at x" is now an
hoelzl@51732
  2701
   abbreviation for "at x within UNIV"
hoelzl@51732
  2702
wenzelm@53983
  2703
 - Introduce named theorem collections tendsto_intros,
wenzelm@53983
  2704
   continuous_intros, continuous_on_intros and FDERIV_intros. Theorems
wenzelm@53983
  2705
   in tendsto_intros (or FDERIV_intros) are also available as
wenzelm@53983
  2706
   tendsto_eq_intros (or FDERIV_eq_intros) where the right-hand side
wenzelm@53983
  2707
   is replaced by a congruence rule. This allows to apply them as
wenzelm@53983
  2708
   intro rules and then proving equivalence by the simplifier.
hoelzl@51732
  2709
hoelzl@51732
  2710
 - Restructured theories in HOL-Complex_Main:
hoelzl@51732
  2711
hoelzl@51732
  2712
   + Moved RealDef and RComplete into Real
hoelzl@51732
  2713
hoelzl@51732
  2714
   + Introduced Topological_Spaces and moved theorems about
hoelzl@51732
  2715
     topological spaces, filters, limits and continuity to it
hoelzl@51732
  2716
hoelzl@51732
  2717
   + Renamed RealVector to Real_Vector_Spaces
