* Command '\<proof>' is an alias for 'sorry', with different
wenzelm@62312
    13
typesetting. E.g. to produce proof holes in examples and documentation.

    18
* (Co)datatype package:
traytel@62332
    19
  - the predicator :: ('a => bool) => 'a F => bool is now a first-class
traytel@62332
    20
    citizen in bounded natural functors
blanchet@62327
    21
  - "primrec" now allows nested calls through the predicator in addition
blanchet@62327
    22
    to the map function.
traytel@62332
    23
  - "bnf" automatically discharges reflexive proof obligations
traytel@62332
    24
    "bnf" outputs a slightly modified proof obligation expressing rel in
traytel@62332
    25
       terms of map and set
traytel@62332
    26
       (not giving a specification for rel makes this one reflexive)
traytel@62332
    27
    "bnf" outputs a new proof obligation expressing pred in terms of set
traytel@62332
    28
       (not giving a specification for pred makes this one reflexive)
traytel@62332
    29
    INCOMPATIBILITY: manual "bnf" declarations may need adjustment
blanchet@62335
    30
  - Renamed lemmas:
blanchet@62335
    31
      rel_prod_apply ~> rel_prod_inject
blanchet@62335
    32
      pred_prod_apply ~> pred_prod_inject
blanchet@62335
    33
    INCOMPATIBILITY.
blanchet@62327
    34
haftmann@62343
    35
* Compound constants INFIMUM and SUPREMUM are mere abbreviations now.
haftmann@62343
    36
INCOMPATIBILITY.
haftmann@62343
    37
haftmann@62345
    38
* Class semiring_Lcd merged into semiring_Gcd.  INCOMPATIBILITY.
haftmann@62345
    39
haftmann@62347
    40
* Lemma generalization:
haftmann@62347
    41
    realpow_minus_mult ~> power_minus_mult
haftmann@62347
    42
    realpow_Suc_le_self ~> power_Suc_le_self
haftmann@62347
    43
INCOMPATIBILITY.

*** General ***
wenzelm@61337
    50
wenzelm@62168
    51
* Eisbach is now based on Pure instead of HOL. Objects-logics may import
wenzelm@62168
    52
either the theory ~~/src/HOL/Eisbach/Eisbach (for HOL etc.) or
wenzelm@62168
    53
~~/src/HOL/Eisbach/Eisbach_Old_Appl_Syntax (for FOL, ZF etc.). Note that
wenzelm@62168
    54
the HOL-Eisbach session located in ~~/src/HOL/Eisbach/ contains further
wenzelm@62168
    55
examples that do require HOL.
wenzelm@62168
    56
wenzelm@62157
    57
* Better resource usage on all platforms (Linux, Windows, Mac OS X) for
wenzelm@62157
    58
both Isabelle/ML and Isabelle/Scala.  Slightly reduced heap space usage.
wenzelm@62157
    59
wenzelm@62017
    60
* Former "xsymbols" syntax with Isabelle symbols is used by default,
wenzelm@62017
    61
without any special print mode. Important ASCII replacement syntax
wenzelm@62017
    62
remains available under print mode "ASCII", but less important syntax
wenzelm@62017
    63
has been removed (see below).
wenzelm@62017
    64
wenzelm@62109
    65
* Support for more arrow symbols, with rendering in LaTeX and Isabelle
wenzelm@62109
    66
fonts: \<Lleftarrow> \<Rrightarrow> \<longlongleftarrow> \<longlongrightarrow> \<longlonglongleftarrow> \<longlonglongrightarrow>.
wenzelm@62017
    67
wenzelm@62108
    68
* Special notation \<struct> for the first implicit 'structure' in the
wenzelm@62108
    69
context has been discontinued. Rare INCOMPATIBILITY, use explicit
wenzelm@62108
    70
structure name instead, notably in indexed notation with block-subscript
wenzelm@62108
    71
(e.g. \<odot>\<^bsub>A\<^esub>).
wenzelm@62108
    72
wenzelm@62108
    73
* The glyph for \<diamond> in the IsabelleText font now corresponds better to its
wenzelm@62108
    74
counterpart \<box> as quantifier-like symbol. A small diamond is available as
wenzelm@62108
    75
\<diamondop>; the old symbol \<struct> loses this rendering and any special
wenzelm@62108
    76
meaning.
wenzelm@62108
    77
wenzelm@62017
    78
* Syntax for formal comments "-- text" now also supports the symbolic
wenzelm@62017
    79
form "\<comment> text". Command-line tool "isabelle update_cartouches -c" helps
wenzelm@62017
    80
to update old sources.
wenzelm@62017
    81
wenzelm@61337
    82
* Toplevel theorem statements have been simplified as follows:
wenzelm@61337
    83
wenzelm@61337
    84
  theorems             ~>  lemmas
wenzelm@61337
    85
  schematic_lemma      ~>  schematic_goal
wenzelm@61337
    86
  schematic_theorem    ~>  schematic_goal
wenzelm@61337
    87
  schematic_corollary  ~>  schematic_goal
wenzelm@61337
    88
wenzelm@61337
    89
Command-line tool "isabelle update_theorems" updates theory sources
wenzelm@61337
    90
accordingly.
wenzelm@61337
    91
wenzelm@61338
    92
* Toplevel theorem statement 'proposition' is another alias for
wenzelm@61338
    93
'theorem'.
wenzelm@61338
    94
wenzelm@62169
    95
* The old 'defs' command has been removed (legacy since Isabelle2014).
wenzelm@62169
    96
INCOMPATIBILITY, use regular 'definition' instead. Overloaded and/or
wenzelm@62169
    97
deferred definitions require a surrounding 'overloading' block.
wenzelm@62169
    98
wenzelm@61337
    99
wenzelm@60610
   100
*** Prover IDE -- Isabelle/Scala/jEdit ***
wenzelm@60610
   101
wenzelm@60986
   102
* IDE support for the source-level debugger of Poly/ML, to work with
wenzelm@62253
   103
Isabelle/ML and official Standard ML. Option "ML_debugger" and commands
wenzelm@62253
   104
'ML_file_debug', 'ML_file_no_debug', 'SML_file_debug',
wenzelm@62253
   105
'SML_file_no_debug' control compilation of sources with or without
wenzelm@62253
   106
debugging information. The Debugger panel allows to set breakpoints (via
wenzelm@62253
   107
context menu), step through stopped threads, evaluate local ML
wenzelm@62253
   108
expressions etc. At least one Debugger view needs to be active to have
wenzelm@62253
   109
any effect on the running ML program.
wenzelm@60984
   110
wenzelm@61803
   111
* The State panel manages explicit proof state output, with dynamic
wenzelm@61803
   112
auto-update according to cursor movement. Alternatively, the jEdit
wenzelm@61803
   113
action "isabelle.update-state" (shortcut S+ENTER) triggers manual
wenzelm@61803
   114
update.
wenzelm@61729
   115
wenzelm@61729
   116
* The Output panel no longer shows proof state output by default, to
wenzelm@61729
   117
avoid GUI overcrowding. INCOMPATIBILITY, use the State panel instead or
wenzelm@61729
   118
enable option "editor_output_state".
wenzelm@61215
   119
wenzelm@61803
   120
* The text overview column (status of errors, warnings etc.) is updated
wenzelm@61803
   121
asynchronously, leading to much better editor reactivity. Moreover, the
wenzelm@61803
   122
full document node content is taken into account. The width of the
wenzelm@61803
   123
column is scaled according to the main text area font, for improved
wenzelm@61803
   124
visibility.
wenzelm@61803
   125
wenzelm@61803
   126
* The main text area no longer changes its color hue in outdated
wenzelm@61803
   127
situations. The text overview column takes over the role to indicate
wenzelm@61803
   128
unfinished edits in the PIDE pipeline. This avoids flashing text display
wenzelm@61803
   129
due to ad-hoc updates by auxiliary GUI components, such as the State
wenzelm@61803
   130
panel.
wenzelm@61803
   131
wenzelm@62254
   132
* Slightly improved scheduling for urgent print tasks (e.g. command
wenzelm@62254
   133
state output, interactive queries) wrt. long-running background tasks.
wenzelm@62017
   134
wenzelm@62017
   135
* Completion of symbols via prefix of \<name> or \<^name> or \name is
wenzelm@62017
   136
always possible, independently of the language context. It is never
wenzelm@62017
   137
implicit: a popup will show up unconditionally.
wenzelm@62017
   138
wenzelm@62017
   139
* Additional abbreviations for syntactic completion may be specified in
wenzelm@62017
   140
$ISABELLE_HOME/etc/abbrevs and $ISABELLE_HOME_USER/etc/abbrevs, with
wenzelm@62017
   141
support for simple templates using ASCII 007 (bell) as placeholder.
wenzelm@62017
   142
wenzelm@62234
   143
* Symbols \<oplus>, \<Oplus>, \<otimes>, \<Otimes>, \<odot>, \<Odot>, \<ominus>, \<oslash> no longer provide abbreviations for
wenzelm@62234
   144
completion like "+o", "*o", ".o" etc. -- due to conflicts with other
wenzelm@62234
   145
ASCII syntax. INCOMPATIBILITY, use plain backslash-completion or define
wenzelm@62234
   146
suitable abbreviations in $ISABELLE_HOME_USER/etc/abbrevs.
wenzelm@62234
   147
wenzelm@61483
   148
* Action "isabelle-emph" (with keyboard shortcut C+e LEFT) controls
wenzelm@61483
   149
emphasized text style; the effect is visible in document output, not in
wenzelm@61483
   150
the editor.
wenzelm@61483
   151
wenzelm@61483
   152
* Action "isabelle-reset" now uses keyboard shortcut C+e BACK_SPACE,
wenzelm@61483
   153
instead of former C+e LEFT.
wenzelm@61483
   154
wenzelm@61512
   155
* The command-line tool "isabelle jedit" and the isabelle.Main
wenzelm@62027
   156
application wrapper treat the default $USER_HOME/Scratch.thy more
wenzelm@61512
   157
uniformly, and allow the dummy file argument ":" to open an empty buffer
wenzelm@61512
   158
instead.
wenzelm@61512
   159
wenzelm@62017
   160
* New command-line tool "isabelle jedit_client" allows to connect to an
wenzelm@62017
   161
already running Isabelle/jEdit process. This achieves the effect of
wenzelm@62017
   162
single-instance applications seen on common GUI desktops.
wenzelm@62017
   163
wenzelm@61529
   164
* The default look-and-feel for Linux is the traditional "Metal", which
wenzelm@61529
   165
works better with GUI scaling for very high-resolution displays (e.g.
wenzelm@61529
   166
4K). Moreover, it is generally more robust than "Nimbus".
wenzelm@61529
   167
wenzelm@62163
   168
* Update to jedit-5.3.0, with improved GUI scaling and support of
wenzelm@62163
   169
high-resolution displays (e.g. 4K).
wenzelm@62163
   170
wenzelm@62034
   171
* The main Isabelle executable is managed as single-instance Desktop
wenzelm@62034
   172
application uniformly on all platforms: Linux, Windows, Mac OS X.
wenzelm@62034
   173
wenzelm@60610
   174
wenzelm@61405
   175
*** Document preparation ***
wenzelm@61405
   176
wenzelm@62017
   177
* Commands 'paragraph' and 'subparagraph' provide additional section
wenzelm@62017
   178
headings. Thus there are 6 levels of standard headings, as in HTML.
wenzelm@62017
   179
wenzelm@62017
   180
* Command 'text_raw' has been clarified: input text is processed as in
wenzelm@62017
   181
'text' (with antiquotations and control symbols). The key difference is
wenzelm@62017
   182
the lack of the surrounding isabelle markup environment in output.
wenzelm@62017
   183
wenzelm@62017
   184
* Text is structured in paragraphs and nested lists, using notation that
wenzelm@62017
   185
is similar to Markdown. The control symbols for list items are as
wenzelm@62017
   186
follows:
wenzelm@62017
   187
wenzelm@62017
   188
  \<^item>  itemize
wenzelm@62017
   189
  \<^enum>  enumerate
wenzelm@62017
   190
  \<^descr>  description
wenzelm@62017
   191
wenzelm@61491
   192
* There is a new short form for antiquotations with a single argument
wenzelm@61491
   193
that is a cartouche: \<^name>\<open>...\<close> is equivalent to @{name \<open>...\<close>} and
wenzelm@61595
   194
\<open>...\<close> without control symbol is equivalent to @{cartouche \<open>...\<close>}.
wenzelm@61595
   195
\<^name> without following cartouche is equivalent to @{name}. The
wenzelm@61501
   196
standard Isabelle fonts provide glyphs to render important control
wenzelm@61501
   197
symbols, e.g. "\<^verbatim>", "\<^emph>", "\<^bold>".
wenzelm@61491
   198
wenzelm@61595
   199
* Antiquotations @{noindent}, @{smallskip}, @{medskip}, @{bigskip} with
wenzelm@61595
   200
corresponding control symbols \<^noindent>, \<^smallskip>, \<^medskip>, \<^bigskip> specify spacing formally, using
wenzelm@61595
   201
standard LaTeX macros of the same names.
wenzelm@61595
   202
wenzelm@61491
   203
* Antiquotation @{cartouche} in Isabelle/Pure is the same as @{text}.
wenzelm@61491
   204
Consequently, \<open>...\<close> without any decoration prints literal quasi-formal
wenzelm@61492
   205
text. Command-line tool "isabelle update_cartouches -t" helps to update
wenzelm@61492
   206
old sources, by approximative patching of the content of string and
wenzelm@61492
   207
cartouche tokens seen in theory sources.
wenzelm@61491
   208
wenzelm@61491
   209
* The @{text} antiquotation now ignores the antiquotation option
wenzelm@61491
   210
"source". The given text content is output unconditionally, without any
wenzelm@61491
   211
surrounding quotes etc. Subtle INCOMPATIBILITY, put quotes into the
wenzelm@61494
   212
argument where they are really intended, e.g. @{text \<open>"foo"\<close>}. Initial
wenzelm@61494
   213
or terminal spaces are ignored.
wenzelm@61491
   214
wenzelm@62017
   215
* Antiquotations @{emph} and @{bold} output LaTeX source recursively,
wenzelm@62017
   216
adding appropriate text style markup. These may be used in the short
wenzelm@62017
   217
form \<^emph>\<open>...\<close> and \<^bold>\<open>...\<close>.
wenzelm@62017
   218
wenzelm@62017
   219
* Document antiquotation @{footnote} outputs LaTeX source recursively,
wenzelm@62017
   220
marked as \footnote{}. This may be used in the short form \<^footnote>\<open>...\<close>.
wenzelm@62017
   221
wenzelm@62017
   222
* Antiquotation @{verbatim [display]} supports option "indent".
wenzelm@62017
   223
wenzelm@62017
   224
* Antiquotation @{theory_text} prints uninterpreted theory source text
wenzelm@62231
   225
(Isar outer syntax with command keywords etc.). This may be used in the
wenzelm@62231
   226
short form \<^theory_text>\<open>...\<close>. @{theory_text [display]} supports option "indent".
wenzelm@62017
   227
wenzelm@62017
   228
* Antiquotation @{doc ENTRY} provides a reference to the given
wenzelm@62017
   229
documentation, with a hyperlink in the Prover IDE.
wenzelm@62017
   230
wenzelm@62017
   231
* Antiquotations @{command}, @{method}, @{attribute} print checked
wenzelm@62017
   232
entities of the Isar language.
wenzelm@62017
   233
wenzelm@61471
   234
* HTML presentation uses the standard IsabelleText font and Unicode
wenzelm@61471
   235
rendering of Isabelle symbols like Isabelle/Scala/jEdit.  The former
wenzelm@61488
   236
print mode "HTML" loses its special meaning.
wenzelm@61471
   237
wenzelm@61405
   238
wenzelm@60406
   239
*** Isar ***
wenzelm@60406
   240
wenzelm@62205
   241
* Local goals ('have', 'show', 'hence', 'thus') allow structured rule
wenzelm@62205
   242
statements like fixes/assumes/shows in theorem specifications, but the
wenzelm@62205
   243
notation is postfix with keywords 'if' (or 'when') and 'for'. For
wenzelm@60555
   244
example:
wenzelm@60414
   245
wenzelm@60414
   246
  have result: "C x y"
wenzelm@60414
   247
    if "A x" and "B y"
wenzelm@60414
   248
    for x :: 'a and y :: 'a
wenzelm@60414
   249
    <proof>
wenzelm@60414
   250
wenzelm@60449
   251
The local assumptions are bound to the name "that". The result is
wenzelm@60449
   252
exported from context of the statement as usual. The above roughly
wenzelm@60414
   253
corresponds to a raw proof block like this:
wenzelm@60414
   254
wenzelm@60414
   255
  {
wenzelm@60414
   256
    fix x :: 'a and y :: 'a
wenzelm@60449
   257
    assume that: "A x" "B y"
wenzelm@60414
   258
    have "C x y" <proof>
wenzelm@60414
   259
  }
wenzelm@60414
   260
  note result = this
wenzelm@60406
   261
wenzelm@60555
   262
The keyword 'when' may be used instead of 'if', to indicate 'presume'
wenzelm@60555
   263
instead of 'assume' above.
wenzelm@60555
   264
wenzelm@61733
   265
* Assumptions ('assume', 'presume') allow structured rule statements
wenzelm@61733
   266
using 'if' and 'for', similar to 'have' etc. above. For example:

   270
    for x :: 'a and y :: 'a
wenzelm@61658
   271
wenzelm@61658
   272
This assumes "\<And>x y::'a. A x \<Longrightarrow> B y \<Longrightarrow> C x y" and produces a general
wenzelm@61658

result as usual: "A ?x \<Longrightarrow> B ?y \<Longrightarrow> C ?x ?y".
wenzelm@61658

Vacuous quantification in assumptions is omitted, i.e. a for-context
wenzelm@61658
   276
only effects propositions according to actual use of variables. For
wenzelm@61658
   277
example:
wenzelm@61658

wenzelm@61658
   279
  assume "A x" and "B y" for x and y
wenzelm@61658
   280
wenzelm@61658

wenzelm@61658
   282
wenzelm@61658

  assume "\<And>x. A x" and "\<And>y. B y"
wenzelm@61658
   284
wenzelm@60595
   285
* The meaning of 'show' with Pure rule statements has changed: premises
wenzelm@60595
   286
are treated in the sense of 'assume', instead of 'presume'. This means,
wenzelm@62205
   287
a goal like "\<And>x. A x \<Longrightarrow> B x \<Longrightarrow> C x" can be solved completely as
wenzelm@62205
   288
follows:
wenzelm@60595
   289
wenzelm@60595
   290
  show "\<And>x. A x \<Longrightarrow> B x \<Longrightarrow> C x"
wenzelm@60595
   291
wenzelm@60595
   292
or:
wenzelm@60595
   293
wenzelm@60595
   294
  show "C x" if "A x" "B x" for x
wenzelm@60595
   295
wenzelm@60595
   296
Rare INCOMPATIBILITY, the old behaviour may be recovered as follows:
wenzelm@60595
   297
wenzelm@60595
   298
  show "C x" when "A x" "B x" for x
wenzelm@60595
   299
wenzelm@60459

* New command 'consider' states rules for generalized elimination and
wenzelm@60459
   301
case splitting. This is like a toplevel statement "theorem obtains" used
wenzelm@60459
   302
within a proof body; or like a multi-branch 'obtain' without activation
wenzelm@60459
   303
of the local context elements yet.
wenzelm@60459
   304
wenzelm@60455
   305
* Proof method "cases" allows to specify the rule as first entry of
wenzelm@60455
   306
chained facts.  This is particularly useful with 'consider':
wenzelm@60455
   307
wenzelm@60455
   308
  consider (a) A | (b) B | (c) C <proof>
wenzelm@60455
   309
  then have something
wenzelm@60455
   310
  proof cases
wenzelm@60455
   311
    case a
wenzelm@60455

* Command 'case' allows fact name and attribute specification like this:
wenzelm@60565
   322
wenzelm@60565
   323
  case a: (c xs)
wenzelm@60565
   324
  case a [attributes]: (c xs)
wenzelm@60565
   325
wenzelm@60565
   326
Facts that are introduced by invoking the case context are uniformly
wenzelm@60565
   327
qualified by "a"; the same name is used for the cumulative fact. The old
wenzelm@60565
   328
form "case (c xs) [attributes]" is no longer supported. Rare
wenzelm@60565
   329
INCOMPATIBILITY, need to adapt uses of case facts in exotic situations,
wenzelm@60565

and always put attributes in front.

   332
* The standard proof method of commands 'proof' and '..' is now called
wenzelm@60618
   333
"standard" to make semantically clear what it is; the old name "default"
wenzelm@60618
   334
is still available as legacy for some time. Documentation now explains
wenzelm@60618
   335
'..' more accurately as "by standard" instead of "by rule".
wenzelm@60618
   336
wenzelm@62017
   337
* Nesting of Isar goal structure has been clarified: the context after
wenzelm@62017
   338
the initial backwards refinement is retained for the whole proof, within
wenzelm@62017
   339
all its context sections (as indicated via 'next'). This is e.g.
wenzelm@62017
   340
relevant for 'using', 'including', 'supply':
wenzelm@62017
   341
wenzelm@62017
   342
  have "A \<and> A" if a: A for A
wenzelm@62017

* Command 'obtain' binds term abbreviations (via 'is' patterns) in the
wenzelm@62017
   351
proof body as well, abstracted over relevant parameters.
wenzelm@62017
   352
wenzelm@62017
   353
* Improved type-inference for theorem statement 'obtains': separate
wenzelm@62017
   354
parameter scope for of each clause.
wenzelm@62017
   355
wenzelm@62017
   356
* Term abbreviations via 'is' patterns also work for schematic
wenzelm@62017
   357
statements: result is abstracted over unknowns.
wenzelm@62017
   358
wenzelm@60631
   359
* Command 'subgoal' allows to impose some structure on backward
wenzelm@60631
   360
refinements, to avoid proof scripts degenerating into long of 'apply'
wenzelm@60631
   361
sequences. Further explanations and examples are given in the isar-ref
wenzelm@60631
   362
manual.
wenzelm@60631
   363
wenzelm@62017

wenzelm@62017
   365
('apply' scripts).
wenzelm@62017

wenzelm@61166
   367
* Proof method "goal_cases" turns the current subgoals into cases within
wenzelm@61166
   368
the context; the conclusion is bound to variable ?case in each case. For

* The undocumented feature of implicit cases goal1, goal2, goal3, etc.
wenzelm@60617
   392
is marked as legacy, and will be removed eventually. The proof method
wenzelm@60617
   393
"goals" achieves a similar effect within regular Isar; often it can be
wenzelm@60617
   394
done more adequately by other means (e.g. 'consider').
wenzelm@60581
   395
wenzelm@62017

* The vacuous fact "TERM x" may be established "by fact" or as `TERM x`
wenzelm@62017

as well, not just "by this" or "." as before.
wenzelm@60551
   398
wenzelm@60554

* Method "sleep" succeeds after a real-time delay (in seconds). This is

wenzelm@61606
   406
of the command. Previously, for 'locale' and 'sublocale' the default was
wenzelm@61606
   407
optional ('?'). The old synatx '!' has been discontinued.

ballarin@61701

* More gentle suppression of syntax along locale morphisms while
wenzelm@62017
   414
printing terms. Previously 'abbreviation' and 'notation' declarations
wenzelm@62017
   415
would be suppressed for morphisms except term identity. Now
ballarin@61701
   416
'abbreviation' is also kept for morphims that only change the involved
wenzelm@62017
   417
parameters, and only 'notation' is suppressed. This can be of great help
wenzelm@62017
   418
when working with complex locale hierarchies, because proof states are
wenzelm@62017
   419
displayed much more succinctly. It also means that only notation needs
wenzelm@62017
   420
to be redeclared if desired, as illustrated by this example:
ballarin@61701
   421
ballarin@61701
   422
  locale struct = fixes composition :: "'a => 'a => 'a" (infixl "\<cdot>" 65)

  locale morphism =
ballarin@61701

* The 'typedef' command has been upgraded from a partially checked
wenzelm@62017
   461
"axiomatization", to a full definitional specification that takes the
wenzelm@62017
   462
global collection of overloaded constant / type definitions into
wenzelm@62017
   463
account. Type definitions with open dependencies on overloaded
wenzelm@62017
   464
definitions need to be specified as "typedef (overloaded)". This
wenzelm@62017
   465
provides extra robustness in theory construction. Rare INCOMPATIBILITY.
wenzelm@62017
   466
wenzelm@62017
   467
* Qualification of various formal entities in the libraries is done more
wenzelm@62017
   468
uniformly via "context begin qualified definition ... end" instead of
wenzelm@62017
   469
old-style "hide_const (open) ...". Consequently, both the defined
wenzelm@62017
   470
constant and its defining fact become qualified, e.g. Option.is_none and
wenzelm@62017

Option.is_none_def. Occasional INCOMPATIBILITY in applications.

   508
intro rules are omitted: the "cases" and "induct" rules no longer

   509
declare empty case_names, but no case_names at all. This allows to use

* The coercions to type 'real' have been reorganised. The function
wenzelm@62017
   577
'real' is no longer overloaded, but has type 'nat => real' and
wenzelm@62017
   578
abbreviates of_nat for that type. Also 'real_of_int :: int => real'
wenzelm@62017
   579
abbreviates of_int for that type. Other overloaded instances of 'real'
wenzelm@62017

* Sledgehammer:
blanchet@61318
   616
  - The MaSh relevance filter has been sped up.
blanchet@60306
   617
  - Proof reconstruction has been improved, to minimize the incidence of
blanchet@60306
   618
    cases where Sledgehammer gives a proof that does not work.
blanchet@60306
   619
  - Auto Sledgehammer now minimizes and preplays the results.
blanchet@61030
   620
  - Handle Vampire 4.0 proof output without raising exception.
blanchet@61043
   621
  - Eliminated "MASH" environment variable. Use the "MaSh" option in
blanchet@61043
   622
    Isabelle/jEdit instead. INCOMPATIBILITY.
blanchet@61317
   623
  - Eliminated obsolete "blocking" option and related subcommands.
blanchet@60306
   624
blanchet@60310

blanchet@61325
   626
  - Fixed soundness bug in translation of "finite" predicate.
blanchet@61324
   627
  - Fixed soundness bug in "destroy_constrs" optimization.

* (Co)datatype package:
blanchet@61345
   633
  - New commands "lift_bnf" and "copy_bnf" for lifting (copying) a BNF
blanchet@61345
   634
    structure on the raw type to an abstract type defined using typedef.
blanchet@61345
   635
  - Always generate "case_transfer" theorem.
wenzelm@62235
   636
  - For mutual types, generate slightly stronger "rel_induct",
wenzelm@62235
   637
    "rel_coinduct", and "coinduct" theorems. INCOMPATIBLITY.
blanchet@61551
   638
  - Allow discriminators and selectors with the same name as the type
blanchet@61551
   639
    being defined.
blanchet@61551
   640
  - Avoid various internal name clashes (e.g., 'datatype f = f').
traytel@60920
   641
wenzelm@62098

   646
* New diagnostic command print_record for displaying record definitions.
kleing@62118
   647
haftmann@60868
   648
* Division on integers is bootstrapped directly from division on
wenzelm@62017

naturals and uses generic numeral algorithm for computations. Slight
wenzelm@62017
   650
INCOMPATIBILITY, simproc numeral_divmod replaces and generalizes former

haftmann@60516
   654
INCOMPATIBILITY.
haftmann@60516
   655
haftmann@60688
   656
* Class algebraic_semidom introduces common algebraic notions of
wenzelm@62017
   657
integral (semi)domains, particularly units. Although logically subsumed
wenzelm@62017
   658
by fields, is is not a super class of these in order not to burden
wenzelm@62017
   659
fields with notions that are trivial there.
wenzelm@62017
   660
wenzelm@62017
   661
* Class normalization_semidom specifies canonical representants for
wenzelm@62017
   662
equivalence classes of associated elements in an integral (semi)domain.
wenzelm@62017
   663
This formalizes associated elements as well.
haftmann@60688

haftmann@60688
   665
* Abstract specification of gcd/lcm operations in classes semiring_gcd,
wenzelm@62017
   666
semiring_Gcd, semiring_Lcd. Minor INCOMPATIBILITY: facts gcd_nat.commute
wenzelm@62017
   667
and gcd_int.commute are subsumed by gcd.commute, as well as
wenzelm@62017

gcd_nat.assoc and gcd_int.assoc by gcd.assoc.
wenzelm@62017
   669
wenzelm@62017

* Former constants Fields.divide (_ / _) and Divides.div (_ div _) are
wenzelm@62017
   671
logically unified to Rings.divide in syntactic type class Rings.divide,
wenzelm@62017
   672
with infix syntax (_ div _). Infix syntax (_ / _) for field division is
wenzelm@62017
   673
added later as abbreviation in class Fields.inverse. INCOMPATIBILITY,
wenzelm@62017
   674
instantiations must refer to Rings.divide rather than the former
wenzelm@62017
   675
separate constants, hence infix syntax (_ / _) is usually not available
wenzelm@62017
   676
during instantiation.
wenzelm@62017
   677
wenzelm@62017
   678
* New cancellation simprocs for boolean algebras to cancel complementary
wenzelm@62017
   679
terms for sup and inf. For example, "sup x (sup y (- x))" simplifies to
wenzelm@62017
   680
"top". INCOMPATIBILITY.

wenzelm@62205
   684
introduced in the form of an uniformity. Some constants are more general
wenzelm@62205
   685
now, it may be necessary to add type class constraints.

      \<supset>#
blanchet@62209
   705
      \<supseteq>#
Mathias@60397
   706
  - "'a multiset" is no longer an instance of the "order",
Mathias@60397
   707
    "ordered_ab_semigroup_add_imp_le", "ordered_cancel_comm_monoid_diff",
Mathias@60397
   708
    "semilattice_inf", and "semilattice_sup" type classes. The theorems
Mathias@60397
   709
    previously provided by these type classes (directly or indirectly)
Mathias@60397
   710

INCOMPATIBILITY, need to re-adjust some ML names and types accordingly.

wenzelm@60793
   814
* Old tactic shorthands atac, rtac, etac, dtac, ftac have been
wenzelm@60793
   815
discontinued. INCOMPATIBILITY, use regular assume_tac, resolve_tac etc.
wenzelm@60793
   816
instead (with proper context).
wenzelm@60642
   817
wenzelm@60642
   818
* Thm.instantiate (and derivatives) no longer require the LHS of the
wenzelm@60642
   819
instantiation to be certified: plain variables are given directly.
wenzelm@60642
   820
wenzelm@60707
   821
* Subgoal.SUBPROOF and Subgoal.FOCUS combinators use anonymous
wenzelm@60707
   822
quasi-bound variables (like the Simplifier), instead of accidentally
wenzelm@60707
   823
named local fixes. This has the potential to improve stability of proof
wenzelm@60707
   824
tools, but can also cause INCOMPATIBILITY for tools that don't observe
wenzelm@60707
   825
the proof context discipline.
wenzelm@60707
   826
wenzelm@62017
   827
* Isar proof methods are based on a slightly more general type
wenzelm@62017
   828
context_tactic, which allows to change the proof context dynamically
wenzelm@62017
   829
(e.g. to update cases) and indicate explicit Seq.Error results. Former
wenzelm@62017
   830
METHOD_CASES is superseded by CONTEXT_METHOD; further combinators are
wenzelm@62017
   831

maintainability of proofs.

   848
allows to adjust large-scale tests (e.g. AFP) to overall hardware
wenzelm@61602
   849

* Property values in etc/symbols may contain spaces, if written with the
wenzelm@62205

   873
is relevant both for Poly/ML and JVM processes.
wenzelm@61294
   874
wenzelm@62017
   875
* Poly/ML default platform architecture may be changed from 32bit to
wenzelm@62205
   876
64bit via system option ML_system_64. A system restart (and rebuild) is
wenzelm@62205
   877
required after change.
wenzelm@62017
   878
wenzelm@62017
   879
* Poly/ML 5.6 runs natively on x86-windows and x86_64-windows, which
wenzelm@62017
   880
both allow larger heap space than former x86-cygwin.
wenzelm@62017
   881
wenzelm@62157

*** General ***
wenzelm@57941
   891
wenzelm@59939
   892
* Local theory specification commands may have a 'private' or
wenzelm@59990
   893
'qualified' modifier to restrict name space accesses to the local scope,
wenzelm@59939
   894
as provided by some "context begin ... end" block. For example:
wenzelm@59926
   895
wenzelm@59926
   896
  context
wenzelm@59926
   897
  begin

wenzelm@59926
   909
wenzelm@59901
   910
* Command 'experiment' opens an anonymous locale context with private
wenzelm@59901
   911
naming policy.
wenzelm@59901
   912
wenzelm@59951
   913
* Command 'notepad' requires proper nesting of begin/end and its proof
wenzelm@59951
   914
structure in the body: 'oops' is no longer supported here. Minor
wenzelm@59951
   915
INCOMPATIBILITY, use 'sorry' instead.
wenzelm@59951
   916
wenzelm@59951
   917
* Command 'named_theorems' declares a dynamic fact within the context,
wenzelm@59951
   918
together with an attribute to maintain the content incrementally. This
wenzelm@59951
   919
supersedes functor Named_Thms in Isabelle/ML, but with a subtle change
wenzelm@59951
   920
of semantics due to external visual order vs. internal reverse order.
wenzelm@59951
   921
wenzelm@59951
   922
* 'find_theorems': search patterns which are abstractions are
wenzelm@59951
   923
schematically expanded before search. Search results match the naive
wenzelm@59951
   924
expectation more closely, particularly wrt. abbreviations.
wenzelm@59951
   925
INCOMPATIBILITY.
wenzelm@59648
   926
wenzelm@59569
   927
* Commands 'method_setup' and 'attribute_setup' now work within a local
wenzelm@59569
   928
theory context.
wenzelm@57941
   929
wenzelm@58928
   930
* Outer syntax commands are managed authentically within the theory
wenzelm@59569
   931
context, without implicit global state. Potential for accidental
wenzelm@58928
   932
INCOMPATIBILITY, make sure that required theories are really imported.
wenzelm@58928
   933
wenzelm@60115
   934
* Historical command-line terminator ";" is no longer accepted (and
wenzelm@60115
   935
already used differently in Isar). Minor INCOMPATIBILITY, use "isabelle
wenzelm@60115
   936
update_semicolons" to remove obsolete semicolons from old theory
wenzelm@60115
   937
sources.
wenzelm@60115
   938
wenzelm@59951
   939
* Structural composition of proof methods (meth1; meth2) in Isar
wenzelm@59951
   940
corresponds to (tac1 THEN_ALL_NEW tac2) in ML.
haftmann@59105
   941
wenzelm@60119
   942
* The Eisbach proof method language allows to define new proof methods
wenzelm@60119
   943
by combining existing ones with their usual syntax. The "match" proof
wenzelm@60119
   944
method provides basic fact/term matching in addition to
wenzelm@60119
   945
premise/conclusion matching through Subgoal.focus, and binds fact names
wenzelm@60288
   946
from matches as well as term patterns within matches. The Isabelle
wenzelm@60288
   947
documentation provides an entry "eisbach" for the Eisbach User Manual.
wenzelm@60288

wenzelm@58524
   952
wenzelm@59569
   953
* Improved folding mode "isabelle" based on Isar syntax. Alternatively,
wenzelm@59569
   954
the "sidekick" mode may be used for document structure.
wenzelm@59569
   955
wenzelm@59569
   956
* Extended bracket matching based on Isar language structure. System
wenzelm@59569
   957
option jedit_structure_limit determines maximum number of lines to scan
wenzelm@59569
   958
in the buffer.
wenzelm@58758
   959
wenzelm@58540
   960
* Support for BibTeX files: context menu, context-sensitive token
wenzelm@58540
   961
marker, SideKick parser.
wenzelm@58524
   962
wenzelm@58551
   963
* Document antiquotation @{cite} provides formal markup, which is
wenzelm@60265
   964
interpreted semi-formally based on .bib files that happen to be open in
wenzelm@60265
   965
the editor (hyperlinks, completion etc.).
wenzelm@58551
   966
wenzelm@58785
   967
* Less waste of vertical space via negative line spacing (see Global
wenzelm@58785
   968
Options / Text Area).
wenzelm@58785
   969
wenzelm@60089
   970
* Improved graphview panel with optional output of PNG or PDF, for
wenzelm@60273
   971
display of 'thy_deps', 'class_deps' etc.
wenzelm@60009
   972
wenzelm@60115
   973
* The commands 'thy_deps' and 'class_deps' allow optional bounds to
wenzelm@60115
   974
restrict the visualized hierarchy.
wenzelm@60093
   975
wenzelm@60072
   976
* Improved scheduling for asynchronous print commands (e.g. provers
wenzelm@60072
   977
managed by the Sledgehammer panel) wrt. ongoing document processing.

*** Document preparation ***
wenzelm@59951
   981
wenzelm@59951
   982
* Document markup commands 'chapter', 'section', 'subsection',
wenzelm@59951
   983
'subsubsection', 'text', 'txt', 'text_raw' work uniformly in any
wenzelm@59951
   984
context, even before the initial 'theory' command. Obsolete proof
wenzelm@59951
   985
commands 'sect', 'subsect', 'subsubsect', 'txt_raw' have been
wenzelm@59951
   986
discontinued, use 'section', 'subsection', 'subsubsection', 'text_raw'
wenzelm@59951
   987
instead. The old 'header' command is still retained for some time, but
wenzelm@59951
   988
should be replaced by 'chapter', 'section' etc. (using "isabelle
wenzelm@59951
   989
update_header"). Minor INCOMPATIBILITY.
wenzelm@59951
   990
wenzelm@60009
   991
* Official support for "tt" style variants, via \isatt{...} or
wenzelm@60009
   992
\begin{isabellett}...\end{isabellett}. The somewhat fragile \verb or
wenzelm@60009
   993
verbatim environment of LaTeX is no longer used. This allows @{ML} etc.
wenzelm@60009
   994
as argument to other macros (such as footnotes).
wenzelm@60009
   995
wenzelm@60009
   996
* Document antiquotation @{verbatim} prints ASCII text literally in "tt"
wenzelm@60009
   997
style.
wenzelm@60009
   998
wenzelm@60009
   999
* Discontinued obsolete option "document_graph": session_graph.pdf is
wenzelm@60009
  1000
produced unconditionally for HTML browser_info and PDF-LaTeX document.
wenzelm@60009
  1001
wenzelm@59951
  1002
* Diagnostic commands and document markup commands within a proof do not
wenzelm@59951
  1003
affect the command tag for output. Thus commands like 'thm' are subject
wenzelm@59951
  1004
to proof document structure, and no longer "stick out" accidentally.
wenzelm@59951
  1005
Commands 'text' and 'txt' merely differ in the LaTeX style, not their
wenzelm@59951
  1006
tags. Potential INCOMPATIBILITY in exotic situations.
wenzelm@59951
  1007
wenzelm@59951
  1008
* System option "pretty_margin" is superseded by "thy_output_margin",
wenzelm@59951
  1009
which is also accessible via document antiquotation option "margin".
wenzelm@59951
  1010
Only the margin for document output may be changed, but not the global
wenzelm@59951
  1011
pretty printing: that is 76 for plain console output, and adapted
wenzelm@59951
  1012
dynamically in GUI front-ends. Implementations of document
wenzelm@59951
  1013
antiquotations need to observe the margin explicitly according to
wenzelm@59951
  1014
Thy_Output.string_of_margin. Minor INCOMPATIBILITY.
wenzelm@59951
  1015
wenzelm@60299
  1016
* Specification of 'document_files' in the session ROOT file is
wenzelm@60299
  1017
mandatory for document preparation. The legacy mode with implicit
wenzelm@60299
  1018
copying of the document/ directory is no longer supported. Minor

INCOMPATIBILITY.

  1023
wenzelm@59835
  1024
* Proof methods with explicit instantiation ("rule_tac", "subgoal_tac"
wenzelm@59835
  1025
etc.) allow an optional context of local variables ('for' declaration):
wenzelm@59835
  1026
these variables become schematic in the instantiated theorem; this
wenzelm@59835
  1027
behaviour is analogous to 'for' in attributes "where" and "of".
wenzelm@59835
  1028
Configuration option rule_insts_schematic (default false) controls use
wenzelm@59835
  1029
of schematic variables outside the context. Minor INCOMPATIBILITY,
wenzelm@59835
  1030
declare rule_insts_schematic = true temporarily and update to use local
wenzelm@59835
  1031
variable declarations or dummy patterns instead.
wenzelm@59835
  1032
wenzelm@60009
  1033
* Explicit instantiation via attributes "where", "of", and proof methods
wenzelm@60009
  1034
"rule_tac" with derivatives like "subgoal_tac" etc. admit dummy patterns
wenzelm@60009
  1035
("_") that stand for anonymous local variables.
wenzelm@60009
  1036
wenzelm@59951
  1037
* Generated schematic variables in standard format of exported facts are
wenzelm@59951
  1038
incremented to avoid material in the proof context. Rare
wenzelm@59951
  1039
INCOMPATIBILITY, explicit instantiation sometimes needs to refer to
wenzelm@59951
  1040
different index.
wenzelm@59951
  1041
wenzelm@60010
  1042
* Lexical separation of signed and unsigned numerals: categories "num"
wenzelm@60010
  1043
and "float" are unsigned. INCOMPATIBILITY: subtle change in precedence
wenzelm@60010
  1044
of numeral signs, particularly in expressions involving infix syntax
wenzelm@60010
  1045
like "(- 1) ^ n".
haftmann@58410
  1046
wenzelm@58421
  1047
* Old inner token category "xnum" has been discontinued.  Potential
wenzelm@58421
  1048
INCOMPATIBILITY for exotic syntax: may use mixfix grammar with "num"
wenzelm@58421
  1049
token category instead.

  - The rule "set_cases" is now registered with the "[cases set]"
blanchet@57990
  1082
    attribute. This can influence the behavior of the "cases" proof
blanchet@57990
  1083
    method when more than one case rule is applicable (e.g., an
blanchet@57990
  1084
    assumption is of the form "w : set ws" and the method "cases w"
blanchet@57990
  1085
    is invoked). The solution is to specify the case rule explicitly
blanchet@57990
  1086
    (e.g. "cases w rule: widget.exhaust").

  - Lifting and Transfer setup for basic HOL types sum and prod (also
wenzelm@60114
  1097
    option) is now performed by the BNF package. Theories Lifting_Sum,
wenzelm@60114
  1098
    Lifting_Product and Lifting_Option from Main became obsolete and
wenzelm@60114
  1099
    were removed. Changed definitions of the relators rel_prod and
wenzelm@60114
  1100
    rel_sum (using inductive).
traytel@60111
  1101
    INCOMPATIBILITY: use rel_prod.simps and rel_sum.simps instead
wenzelm@60114
  1102
    of rel_prod_def and rel_sum_def.
wenzelm@60114
  1103
    Minor INCOMPATIBILITY: (rarely used by name) transfer theorem names
wenzelm@60114
  1104
    changed (e.g. map_prod_transfer ~> prod.map_transfer).
wenzelm@60261

  - Fixed soundness bug related to the strict and non-strict subset
blanchet@59039
  1125
    operations.
blanchet@59039
  1126
blanchet@57737
  1127
* Sledgehammer:
blanchet@59511
  1128
  - CVC4 is now included with Isabelle instead of CVC3 and run by
blanchet@59511
  1129
    default.
blanchet@59965
  1130
  - Z3 is now always enabled by default, now that it is fully open
blanchet@59965
  1131
    source. The "z3_non_commercial" option is discontinued.
blanchet@57737
  1132
  - Minimization is now always enabled by default.
wenzelm@60010
  1133
    Removed sub-command:

  - Proof reconstruction, both one-liners and Isar, has been
blanchet@59039

* Lifting: command 'lift_definition' allows to execute lifted constants
wenzelm@60261
  1155
that have as a return type a datatype containing a subtype. This
wenzelm@60261
  1156
overcomes long-time limitations in the area of code generation and
wenzelm@60261
  1157
lifting, and avoids tedious workarounds.
kuncar@60258
  1158
wenzelm@60009
  1159
* Command and antiquotation "value" provide different evaluation slots
wenzelm@60009

  1161
Minor INCOMPATIBILITY.
wenzelm@60009
  1162
wenzelm@60009

* Add NO_MATCH-simproc, allows to check for syntactic non-equality.
wenzelm@60009
  1164
wenzelm@60009
  1165
* field_simps: Use NO_MATCH-simproc for distribution rules, to avoid
wenzelm@60009
  1166
non-termination in case of distributing a division. With this change
wenzelm@60009
  1167
field_simps is in some cases slightly less powerful, if it fails try to
wenzelm@60009
  1168
add algebra_simps, or use divide_simps. Minor INCOMPATIBILITY.
wenzelm@60009
  1169
wenzelm@60009

  1177
"inverse 0 = 0". Given up separate classes division_ring_inverse_zero,
wenzelm@60009
  1178
field_inverse_zero and linordered_field_inverse_zero. INCOMPATIBILITY.
wenzelm@60009
  1179
wenzelm@60009

additive inverse operation. INCOMPATIBILITY.
wenzelm@60009
  1182
lp15@60020
  1183
* Complex powers and square roots. The functions "ln" and "powr" are now
wenzelm@60025
  1184
overloaded for types real and complex, and 0 powr y = 0 by definition.
wenzelm@60025

INCOMPATIBILITY: type constraints may be necessary.
lp15@60020

wenzelm@60009
  1187
* The functions "sin" and "cos" are now defined for any type of sort
wenzelm@60009
  1188
"{real_normed_algebra_1,banach}" type, so in particular on "real" and
wenzelm@60009
  1189
"complex" uniformly. Minor INCOMPATIBILITY: type constraints may be
wenzelm@60009
  1190
needed.
wenzelm@60009
  1191
wenzelm@60009
  1192
* New library of properties of the complex transcendental functions sin,
wenzelm@60009
  1193
cos, tan, exp, Ln, Arctan, Arcsin, Arccos. Ported from HOL Light.
wenzelm@60009
  1194
wenzelm@60009
  1195
* The factorial function, "fact", now has type "nat => 'a" (of a sort
wenzelm@60009
  1196
that admits numeric types including nat, int, real and complex.
wenzelm@60009
  1197
INCOMPATIBILITY: an expression such as "fact 3 = 6" may require a type
wenzelm@60009
  1198
constraint, and the combination "real (fact k)" is likely to be
wenzelm@60009
  1199
unsatisfactory. If a type conversion is still necessary, then use
wenzelm@60009
  1200
"of_nat (fact k)" or "real_of_nat (fact k)".
wenzelm@60009
  1201
wenzelm@60009
  1202
* Removed functions "natfloor" and "natceiling", use "nat o floor" and
wenzelm@60009
  1203
"nat o ceiling" instead. A few of the lemmas have been retained and
wenzelm@60009
  1204
adapted: in their names "natfloor"/"natceiling" has been replaced by
wenzelm@60009
  1205
"nat_floor"/"nat_ceiling".
wenzelm@60009
  1206
wenzelm@60009
  1207
* Qualified some duplicated fact names required for boostrapping the
wenzelm@60009
  1208
type class hierarchy:
wenzelm@60009

  ab_add_uminus_conv_diff ~> diff_conv_add_uminus
wenzelm@60009
  1210
  field_inverse_zero ~> inverse_zero

  field_divide_inverse ~> divide_inverse
wenzelm@60009

  1213
Minor INCOMPATIBILITY.
wenzelm@60009
  1214
wenzelm@60009

* Eliminated fact duplicates:
wenzelm@60009
  1216
  mult_less_imp_less_right ~> mult_right_less_imp_less
wenzelm@60009
  1217
  mult_less_imp_less_left ~> mult_left_less_imp_less

  1218
Minor INCOMPATIBILITY.
wenzelm@60009
  1219
wenzelm@60009
  1220
* Fact consolidation: even_less_0_iff is subsumed by
wenzelm@60009
  1221
double_add_less_zero_iff_single_add_less_zero (simp by default anyway).
wenzelm@60009
  1222
wenzelm@60009
  1223
* Generalized and consolidated some theorems concerning divsibility:
wenzelm@60009

wenzelm@60009
  1225
  dvd_plus_eq_right ~> dvd_add_right_iff

wenzelm@60009
  1227
Minor INCOMPATIBILITY.
wenzelm@60009

  even_def ~> even_iff_mod_2_eq_zero
wenzelm@60009
  1232
INCOMPATIBILITY.
wenzelm@60009

  1235
INCOMPATIBILITY.
wenzelm@60009
  1236
wenzelm@60009
  1237
* Bootstrap of listsum as special case of abstract product over lists.
wenzelm@60009
  1238
Fact rename:

INCOMPATIBILITY.
wenzelm@60009

* Product over lists via constant "listprod".
wenzelm@60009
  1243
wenzelm@60009

wenzelm@59569
  1248
generated code in target languages in HOL/Library/Code_Test. See
wenzelm@59569
  1249

  1250
wenzelm@60009
  1251
* Library/Multiset:
blanchet@59813
  1252
  - Introduced "replicate_mset" operation.
blanchet@59813
  1253
  - Introduced alternative characterizations of the multiset ordering in
blanchet@59813
  1254
    "Library/Multiset_Order".
blanchet@59958
  1255
  - Renamed multiset ordering:

blanchet@59986
  1264
    INCOMPATIBILITY.
blanchet@59813

* Library/Sum_of_Squares: simplified and improved "sos" method. Always
wenzelm@60009
  1283
use local CSDP executable, which is much faster than the NEOS server.
wenzelm@60009
  1284
The "sos_cert" functionality is invoked as "sos" with additional

wenzelm@60009
  1287
* HOL-Decision_Procs: New counterexample generator quickcheck
wenzelm@60009
  1288
[approximation] for inequalities of transcendental functions. Uses
wenzelm@60009
  1289
hardware floating point arithmetic to randomly discover potential

* HOL-Probability: Reworked measurability prover
wenzelm@60010
  1295
  - applies destructor rules repeatedly
hoelzl@59354
  1296
  - removed application splitting (replaced by destructor rule)
wenzelm@59569

wenzelm@60009
  1306
* Subtle change of name space policy: undeclared entries are now
wenzelm@60009
  1307
considered inaccessible, instead of accessible via the fully-qualified
wenzelm@60009
  1308
internal name. This mainly affects Name_Space.intern (and derivatives),
wenzelm@60009
  1309
which may produce an unexpected Long_Name.hidden prefix. Note that
wenzelm@60010
  1310
contemporary applications use the strict Name_Space.check (and
wenzelm@60009
  1311
derivatives) instead, which is not affected by the change. Potential
wenzelm@60009
  1312
INCOMPATIBILITY in rare applications of Name_Space.intern.
wenzelm@59951
  1313
wenzelm@60094
  1314
* Subtle change of error semantics of Toplevel.proof_of: regular user

  1315
ERROR instead of internal Toplevel.UNDEF.
wenzelm@60094
  1316
wenzelm@59951
  1317
* Basic combinators map, fold, fold_map, split_list, apply are available
wenzelm@59951

wenzelm@59951
  1323
* Former combinators NAMED_CRITICAL and CRITICAL for central critical
wenzelm@59951

wenzelm@59951
  1325
Multithreading.synchronized and its high-level derivative
wenzelm@59951
  1326
Synchronized.var (which is usually sufficient in applications). Subtle
wenzelm@59951
  1327
INCOMPATIBILITY: synchronized access needs to be atomic and cannot be
wenzelm@59951
  1328
nested.
wenzelm@59951
  1329
wenzelm@60009
  1330
* Synchronized.value (ML) is actually synchronized (as in Scala): subtle
wenzelm@60009
  1331
change of semantics with minimal potential for INCOMPATIBILITY.
wenzelm@59899
  1332
wenzelm@59621
  1333
* The main operations to certify logical entities are Thm.ctyp_of and
wenzelm@59621
  1334
Thm.cterm_of with a local context; old-style global theory variants are
wenzelm@59621

INCOMPATIBILITY, need to use qualified Thm.prop_of, Thm.cterm_of,
wenzelm@59582
  1340
Thm.term_of etc.
wenzelm@59582
  1341
wenzelm@58963
  1342
* Proper context for various elementary tactics: assume_tac,
wenzelm@59498
  1343
resolve_tac, eresolve_tac, dresolve_tac, forward_tac, match_tac,
wenzelm@59498
  1344
compose_tac, Splitter.split_tac etc. INCOMPATIBILITY.
wenzelm@58956
  1345
blanchet@58066
  1346
* Tactical PARALLEL_ALLGOALS is the most common way to refer to
blanchet@58066
  1347
PARALLEL_GOALS.
blanchet@58066
  1348
wenzelm@59564
  1349
* Goal.prove_multi is superseded by the fully general Goal.prove_common,
wenzelm@59564
  1350
which also allows to specify a fork priority.
wenzelm@59564
  1351
wenzelm@59936
  1352
* Antiquotation @{command_spec "COMMAND"} is superseded by
wenzelm@59936
  1353
@{command_keyword COMMAND} (usually without quotes and with PIDE
wenzelm@59936
  1354
markup). Minor INCOMPATIBILITY.
wenzelm@59936
  1355
wenzelm@60009
  1356
* Cartouches within ML sources are turned into values of type

* The Isabelle tool "update_cartouches" changes theory files to use
wenzelm@59951
  1363
cartouches instead of old-style {* verbatim *} or `alt_string` tokens.
wenzelm@59951
  1364
wenzelm@60106
  1365
* The Isabelle tool "build" provides new options -X, -k, -x.
wenzelm@59951
  1366
wenzelm@59951
  1367
* Discontinued old-fashioned "codegen" tool. Code generation can always
wenzelm@59951
  1368
be externally triggered using an appropriate ROOT file plus a
wenzelm@59951
  1369
corresponding theory. Parametrization is possible using environment
wenzelm@59951
  1370
variables, or ML snippets in the most extreme cases. Minor
wenzelm@59951
  1371
INCOMPATIBILITY.
wenzelm@58842

wenzelm@59200
  1373
* JVM system property "isabelle.threads" determines size of Scala thread
wenzelm@59200
  1374
pool, like Isabelle system option "threads" for ML.
wenzelm@59200
  1375
wenzelm@59201
  1376
* JVM system property "isabelle.laf" determines the default Swing
wenzelm@59201

wenzelm@54702
  1388
*** General ***
wenzelm@54702
  1389
wenzelm@57452
  1390
* Support for official Standard ML within the Isabelle context.
wenzelm@57452
  1391
Command 'SML_file' reads and evaluates the given Standard ML file.
wenzelm@57452
  1392
Toplevel bindings are stored within the theory context; the initial
wenzelm@57452
  1393
environment is restricted to the Standard ML implementation of
wenzelm@57452
  1394
Poly/ML, without the add-ons of Isabelle/ML.  Commands 'SML_import'
wenzelm@57452
  1395
and 'SML_export' allow to exchange toplevel bindings between the two
wenzelm@57452
  1396
separate environments.  See also ~~/src/Tools/SML/Examples.thy for
wenzelm@57452
  1397
some examples.
wenzelm@56499
  1398
wenzelm@57504
  1399
* Standard tactics and proof methods such as "clarsimp", "auto" and
wenzelm@57504
  1400
"safe" now preserve equality hypotheses "x = expr" where x is a free
wenzelm@57504
  1401
variable.  Locale assumptions and chained facts containing "x"
wenzelm@57504
  1402
continue to be useful.  The new method "hypsubst_thin" and the
wenzelm@57504
  1403
configuration option "hypsubst_thin" (within the attribute name space)
wenzelm@57504
  1404
restore the previous behavior.  INCOMPATIBILITY, especially where
wenzelm@57504
  1405
induction is done after these methods or when the names of free and
wenzelm@57504
  1406
bound variables clash.  As first approximation, old proofs may be
wenzelm@57504
  1407
repaired by "using [[hypsubst_thin = true]]" in the critical spot.
wenzelm@57504
  1408
wenzelm@56232
  1409
* More static checking of proof methods, which allows the system to
wenzelm@56232
  1410
form a closure over the concrete syntax.  Method arguments should be
wenzelm@56232
  1411
processed in the original proof context as far as possible, before
wenzelm@56232
  1412
operating on the goal state.  In any case, the standard discipline for
wenzelm@56232
  1413
subgoal-addressing needs to be observed: no subgoals or a subgoal
wenzelm@56232
  1414
number that is out of range produces an empty result sequence, not an
wenzelm@56232
  1415
exception.  Potential INCOMPATIBILITY for non-conformant tactical
wenzelm@56232
  1416
proof tools.
wenzelm@56232
  1417
wenzelm@57452
  1418
* Lexical syntax (inner and outer) supports text cartouches with
wenzelm@57452
  1419
arbitrary nesting, and without escapes of quotes etc.  The Prover IDE
wenzelm@57452
  1420
supports input via ` (backquote).
wenzelm@57452
  1421
wenzelm@57452
  1422
* The outer syntax categories "text" (for formal comments and document
wenzelm@57452
  1423
markup commands) and "altstring" (for literal fact references) allow
wenzelm@57452
  1424
cartouches as well, in addition to the traditional mix of quotations.
wenzelm@57452
  1425
wenzelm@57452
  1426
* Syntax of document antiquotation @{rail} now uses \<newline> instead
wenzelm@57452
  1427
of "\\", to avoid the optical illusion of escaped backslash within
wenzelm@57491
  1428
string token.  General renovation of its syntax using text cartouches.
wenzelm@57452
  1429
Minor INCOMPATIBILITY.
wenzelm@57452
  1430
wenzelm@57452
  1431
* Discontinued legacy_isub_isup, which was a temporary workaround for
wenzelm@57452
  1432
Isabelle/ML in Isabelle2013-1.  The prover process no longer accepts
wenzelm@57452
  1433
old identifier syntax with \<^isub> or \<^isup>.  Potential
wenzelm@57452
  1434
INCOMPATIBILITY.
wenzelm@57452
  1435
wenzelm@57452
  1436
* Document antiquotation @{url} produces markup for the given URL,
wenzelm@57452
  1437
which results in an active hyperlink within the text.
wenzelm@57452
  1438
wenzelm@57452
  1439
* Document antiquotation @{file_unchecked} is like @{file}, but does
wenzelm@57452
  1440
not check existence within the file-system.
wenzelm@57452
  1441
wenzelm@57452
  1442
* Updated and extended manuals: codegen, datatypes, implementation,
wenzelm@57452
  1443
isar-ref, jedit, system.

*** Prover IDE -- Isabelle/Scala/jEdit ***
wenzelm@54533
  1447
wenzelm@57650
  1448
* Improved Document panel: simplified interaction where every single
wenzelm@57452
  1449
mouse click (re)opens document via desktop environment or as jEdit
wenzelm@57452
  1450
buffer.
wenzelm@57452
  1451
wenzelm@57452
  1452
* Support for Navigator plugin (with toolbar buttons), with connection
wenzelm@57452
  1453
to PIDE hyperlinks.
wenzelm@57452
  1454
wenzelm@57452
  1455
* Auxiliary files ('ML_file' etc.) are managed by the Prover IDE.
wenzelm@57452
  1456
Open text buffers take precedence over copies within the file-system.
wenzelm@57452
  1457
wenzelm@57452
  1458
* Improved support for Isabelle/ML, with jEdit mode "isabelle-ml" for
wenzelm@57452
  1459
auxiliary ML files.
wenzelm@57423
  1460
wenzelm@57423
  1461
* Improved syntactic and semantic completion mechanism, with simple
wenzelm@57423
  1462
templates, completion language context, name-space completion,
wenzelm@57423
  1463
file-name completion, spell-checker completion.
wenzelm@57423
  1464
wenzelm@57423
  1465
* Refined GUI popup for completion: more robust key/mouse event
wenzelm@57423
  1466
handling and propagation to enclosing text area -- avoid loosing
wenzelm@57423
  1467
keystrokes with slow / remote graphics displays.
wenzelm@57423
  1468
wenzelm@57833
  1469
* Completion popup supports both ENTER and TAB (default) to select an
wenzelm@57833
  1470
item, depending on Isabelle options.
wenzelm@57833
  1471
wenzelm@57423
  1472
* Refined insertion of completion items wrt. jEdit text: multiple
wenzelm@57423
  1473
selections, rectangular selections, rectangular selection as "tall
wenzelm@57423
  1474
caret".
wenzelm@56342
  1475
wenzelm@56580
  1476
* Integrated spell-checker for document text, comments etc. with
wenzelm@57423
  1477
completion popup and context-menu.
wenzelm@56554
  1478
wenzelm@56879
  1479
* More general "Query" panel supersedes "Find" panel, with GUI access
wenzelm@56879
  1480
to commands 'find_theorems' and 'find_consts', as well as print
wenzelm@56879
  1481
operations for the context.  Minor incompatibility in keyboard
wenzelm@56879
  1482
shortcuts etc.: replace action isabelle-find by isabelle-query.
wenzelm@56761
  1483
wenzelm@56901
  1484
* Search field for all output panels ("Output", "Query", "Info" etc.)
wenzelm@56901
  1485
to highlight text via regular expression.
wenzelm@56901
  1486
wenzelm@54881
  1487
* Option "jedit_print_mode" (see also "Plugin Options / Isabelle /
wenzelm@54881
  1488
General") allows to specify additional print modes for the prover
wenzelm@54881
  1489
process, without requiring old-fashioned command-line invocation of
wenzelm@54881
  1490
"isabelle jedit -m MODE".
wenzelm@54881
  1491
wenzelm@56505
  1492
* More support for remote files (e.g. http) using standard Java
wenzelm@56505
  1493
networking operations instead of jEdit virtual file-systems.
wenzelm@56505
  1494
wenzelm@57822
  1495
* Empty editors buffers that are no longer required (e.g.\ via theory
wenzelm@57822
  1496
imports) are automatically removed from the document model.
wenzelm@57822
  1497
wenzelm@57869
  1498
* Improved monitor panel.
wenzelm@57869
  1499
wenzelm@56838
  1500
* Improved Console/Scala plugin: more uniform scala.Console output,
wenzelm@56838
  1501
more robust treatment of threads and interrupts.
wenzelm@56838
  1502
wenzelm@56939
  1503
* Improved management of dockable windows: clarified keyboard focus
wenzelm@56939
  1504
and window placement wrt. main editor view; optional menu item to
wenzelm@56939
  1505
"Detach" a copy where this makes sense.
wenzelm@56939
  1506
wenzelm@57452
  1507
* New Simplifier Trace panel provides an interactive view of the
wenzelm@57591
  1508
simplification process, enabled by the "simp_trace_new" attribute
wenzelm@57452
  1509
within the context.

*** Pure ***
wenzelm@55001
  1513
wenzelm@57504
  1514
* Low-level type-class commands 'classes', 'classrel', 'arities' have
wenzelm@57504
  1515
been discontinued to avoid the danger of non-trivial axiomatization
wenzelm@57504
  1516
that is not immediately visible.  INCOMPATIBILITY, use regular
wenzelm@57504
  1517
'instance' command with proof.  The required OFCLASS(...) theorem
wenzelm@57504
  1518
might be postulated via 'axiomatization' beforehand, or the proof
wenzelm@57504
  1519
finished trivially if the underlying class definition is made vacuous
wenzelm@57504
  1520
(without any assumptions).  See also Isabelle/ML operations
wenzelm@57504
  1521
Axclass.class_axiomatization, Axclass.classrel_axiomatization,
wenzelm@57504
  1522
Axclass.arity_axiomatization.
wenzelm@57504
  1523
wenzelm@56245
  1524
* Basic constants of Pure use more conventional names and are always
wenzelm@56245
  1525
qualified.  Rare INCOMPATIBILITY, but with potentially serious
wenzelm@56245
  1526
consequences, notably for tools in Isabelle/ML.  The following
wenzelm@56245
  1527
renaming needs to be applied:
wenzelm@56245
  1528
wenzelm@56245
  1529
  ==             ~>  Pure.eq
wenzelm@56245
  1530
  ==>            ~>  Pure.imp
wenzelm@56245
  1531
  all            ~>  Pure.all
wenzelm@56245
  1532
  TYPE           ~>  Pure.type
wenzelm@56245
  1533
  dummy_pattern  ~>  Pure.dummy_pattern
wenzelm@56245
  1534
wenzelm@56245
  1535
Systematic porting works by using the following theory setup on a
wenzelm@56245
  1536
*previous* Isabelle version to introduce the new name accesses for the
wenzelm@56245
  1537
old constants:
wenzelm@56245
  1538
wenzelm@56245
  1539
setup {*
wenzelm@56245
  1540
  fn thy => thy
wenzelm@56245
  1541
    |> Sign.root_path
wenzelm@56245
  1542
    |> Sign.const_alias (Binding.qualify true "Pure" @{binding eq}) "=="
wenzelm@56245
  1543
    |> Sign.const_alias (Binding.qualify true "Pure" @{binding imp}) "==>"
wenzelm@56245
  1544
    |> Sign.const_alias (Binding.qualify true "Pure" @{binding all}) "all"
wenzelm@56245
  1545
    |> Sign.restore_naming thy
wenzelm@56245
  1546
*}
wenzelm@56245
  1547
wenzelm@56245
  1548
Thus ML antiquotations like @{const_name Pure.eq} may be used already.
wenzelm@56245
  1549
Later the application is moved to the current Isabelle version, and
wenzelm@56245
  1550
the auxiliary aliases are deleted.
wenzelm@56245
  1551
wenzelm@55143
  1552
* Attributes "where" and "of" allow an optional context of local
wenzelm@55143
  1553
variables ('for' declaration): these variables become schematic in the
wenzelm@55143
  1554
instantiated theorem.
wenzelm@55143
  1555
wenzelm@55152
  1556
* Obsolete attribute "standard" has been discontinued (legacy since
wenzelm@55152
  1557
Isabelle2012).  Potential INCOMPATIBILITY, use explicit 'for' context
wenzelm@55152
  1558
where instantiations with schematic variables are intended (for
wenzelm@55152
  1559
declaration commands like 'lemmas' or attributes like "of").  The
wenzelm@55152
  1560
following temporary definition may help to port old applications:
wenzelm@55152
  1561
wenzelm@55152
  1562
  attribute_setup standard =
wenzelm@55152
  1563
    "Scan.succeed (Thm.rule_attribute (K Drule.export_without_context))"
wenzelm@55152
  1564
wenzelm@55001
  1565
* More thorough check of proof context for goal statements and
wenzelm@55006
  1566
attributed fact expressions (concerning background theory, declared
wenzelm@55006
  1567
hyps).  Potential INCOMPATIBILITY, tools need to observe standard
wenzelm@55006
  1568
context discipline.  See also Assumption.add_assumes and the more
wenzelm@55006
  1569
primitive Thm.assume_hyps.
wenzelm@55001
  1570
wenzelm@55108
  1571
* Inner syntax token language allows regular quoted strings "..."
wenzelm@55108
  1572
(only makes sense in practice, if outer syntax is delimited
wenzelm@57452
  1573
differently, e.g. via cartouches).
wenzelm@57452
  1574
wenzelm@57504
  1575
* Command 'print_term_bindings' supersedes 'print_binds' for clarity,
wenzelm@57504
  1576
but the latter is retained some time as Proof General legacy.
wenzelm@57504
  1577
wenzelm@57452

  1616
now deal with conjunctions.  For help with converting proofs, the old
wenzelm@57452
  1617
behaviour of the simplifier can be restored like this: declare/using
wenzelm@57452
  1618
[[simp_legacy_precond]].  This configuration option will disappear
wenzelm@57452
  1619
again in the future.  INCOMPATIBILITY.

wenzelm@57508
  1773
* New internal SAT solver "cdclite" that produces models and proof
wenzelm@57508
  1774
traces.  This solver replaces the internal SAT solvers "enumerate" and
wenzelm@57508
  1775
"dpll".  Applications that explicitly used one of these two SAT
wenzelm@57508
  1776
solvers should use "cdclite" instead. In addition, "cdclite" is now
wenzelm@57508
  1777
the default SAT solver for the "sat" and "satx" proof methods and
wenzelm@57508
  1778
corresponding tactics; the old default can be restored using "declare

[[sat_solver = zchaff_with_proofs]]".  Minor INCOMPATIBILITY.
wenzelm@57508
  1780
wenzelm@57508
  1781
* SMT module: A new version of the SMT module, temporarily called
wenzelm@57508
  1782
"SMT2", uses SMT-LIB 2 and supports recent versions of Z3 (e.g.,
wenzelm@57508
  1783
4.3). The new proof method is called "smt2". CVC3 and CVC4 are also
wenzelm@57508
  1784
supported as oracles. Yices is no longer supported, because no version
wenzelm@57508
  1785
of the solver can handle both SMT-LIB 2 and quantifiers.
wenzelm@57508
  1786
wenzelm@57508
  1787
* Activation of Z3 now works via "z3_non_commercial" system option
wenzelm@57508
  1788
(without requiring restart), instead of former settings variable
wenzelm@57508
  1789
"Z3_NON_COMMERCIAL".  The option can be edited in Isabelle/jEdit menu

* Sledgehammer:
wenzelm@57508
  1793
  - Z3 can now produce Isar proofs.
wenzelm@57508
  1794
  - MaSh overhaul:
blanchet@57532
  1795
    . New SML-based learning algorithms eliminate the dependency on
wenzelm@57508
  1796
      Python and increase performance and reliability.
wenzelm@57508
  1797
    . MaSh and MeSh are now used by default together with the
wenzelm@57508
  1798
      traditional MePo (Meng-Paulson) relevance filter. To disable
wenzelm@57508
  1799
      MaSh, set the "MaSh" system option in Isabelle/jEdit Plugin
wenzelm@57508
  1800
      Options / Isabelle / General to "none".
wenzelm@57508
  1801
  - New option:
wenzelm@57508
  1802
      smt_proofs
wenzelm@57508

INCOMPATIBILITY.
wenzelm@57508
  1808
wenzelm@57508

* Removed solvers remote_cvc3 and remote_z3. Use cvc3 and z3 instead.
wenzelm@57508
  1810
wenzelm@57508
  1811
* Nitpick:
wenzelm@57508
  1812
  - Fixed soundness bug whereby mutually recursive datatypes could
wenzelm@57508
  1813
    take infinite values.
wenzelm@57508
  1814
  - Fixed soundness bug with low-level number functions such as
wenzelm@57508
  1815
    "Abs_Integ" and "Rep_Integ".
wenzelm@57508
  1816
  - Removed "std" option.
wenzelm@57508
  1817
  - Renamed "show_datatypes" to "show_types" and "hide_datatypes" to
wenzelm@57508
  1818
    "hide_types".
wenzelm@57508
  1819
wenzelm@57508
  1820
* Metis: Removed legacy proof method 'metisFT'. Use 'metis
wenzelm@57508
  1821
(full_types)' instead. INCOMPATIBILITY.
wenzelm@57508
  1822
wenzelm@57508
  1823
* Try0: Added 'algebra' and 'meson' to the set of proof methods.
wenzelm@57508
  1824
wenzelm@57508
  1825
* Adjustion of INF and SUP operations:
wenzelm@57508
  1826
  - Elongated constants INFI and SUPR to INFIMUM and SUPREMUM.
wenzelm@57508
  1827
  - Consolidated theorem names containing INFI and SUPR: have INF and
wenzelm@57508
  1828
    SUP instead uniformly.
wenzelm@57508
  1829
  - More aggressive normalization of expressions involving INF and Inf
wenzelm@57508
  1830
    or SUP and Sup.
wenzelm@57508
  1831
  - INF_image and SUP_image do not unfold composition.
wenzelm@57508
  1832
  - Dropped facts INF_comp, SUP_comp.
wenzelm@57508
  1833
  - Default congruence rules strong_INF_cong and strong_SUP_cong, with
wenzelm@57508
  1834
    simplifier implication in premises.  Generalize and replace former
wenzelm@57508
  1835
    INT_cong, SUP_cong

* SUP and INF generalized to conditionally_complete_lattice.
wenzelm@57508
  1840
wenzelm@57508
  1841
* Swapped orientation of facts image_comp and vimage_comp:

* The signature and semantics of Document.Snapshot.cumulate_markup /
wenzelm@55622
  2367
select_markup have been clarified.  Markup is now traversed in the
wenzelm@55622
  2368
order of reports given by the prover: later markup is usually more
wenzelm@55622
  2369
specific and may override results accumulated so far.  The elements

  2370
guard is mandatory and checked precisely.  Subtle INCOMPATIBILITY.

wenzelm@54449
  2377
wenzelm@57504
  2378
* Subtle change of semantics of Thm.eq_thm: theory stamps are not
wenzelm@57504
  2379
compared (according to Thm.thm_ord), but assumed to be covered by the
wenzelm@57504
  2380
current background theory.  Thus equivalent data produced in different
wenzelm@57504
  2381
branches of the theory graph usually coincides (e.g. relevant for
wenzelm@57504
  2382
theory merge).  Note that the softer Thm.eq_thm_prop is often more
wenzelm@57504
  2383
appropriate than Thm.eq_thm.
wenzelm@57504
  2384
wenzelm@57504
  2385
* Proper context for basic Simplifier operations: rewrite_rule,
wenzelm@57504
  2386
rewrite_goals_rule, rewrite_goals_tac etc. INCOMPATIBILITY, need to
wenzelm@57504
  2387
pass runtime Proof.context (and ensure that the simplified entity
wenzelm@57504
  2388
actually belongs to it).
wenzelm@57504
  2389
wenzelm@57504
  2390
* Proper context discipline for read_instantiate and instantiate_tac:
wenzelm@57504
  2391
variables that are meant to become schematic need to be given as
wenzelm@57504
  2392
fixed, and are generalized by the explicit context of local variables.
wenzelm@57504
  2393
This corresponds to Isar attributes "where" and "of" with 'for'
wenzelm@57504
  2394
declaration.  INCOMPATIBILITY, also due to potential change of indices
wenzelm@57504
  2395
of schematic variables.
wenzelm@57504
  2396
wenzelm@56303
  2397
* Moved ML_Compiler.exn_trace and other operations on exceptions to

  2398
structure Runtime.  Minor INCOMPATIBILITY.
wenzelm@56303
  2399
wenzelm@56279
  2400
* Discontinued old Toplevel.debug in favour of system option
wenzelm@57452
  2401
"ML_exception_trace", which may be also declared within the context
wenzelm@57452
  2402
via "declare [[ML_exception_trace = true]]".  Minor INCOMPATIBILITY.
wenzelm@56279
  2403
wenzelm@56281
  2404
* Renamed configuration option "ML_trace" to "ML_source_trace". Minor
wenzelm@56281
  2405
INCOMPATIBILITY.
wenzelm@56281
  2406
wenzelm@56281
  2407
* Configuration option "ML_print_depth" controls the pretty-printing
wenzelm@56281
  2408
depth of the ML compiler within the context.  The old print_depth in
wenzelm@56285
  2409
ML is still available as default_print_depth, but rarely used.  Minor
wenzelm@56285
  2410
INCOMPATIBILITY.
wenzelm@56279
  2411
wenzelm@54449
  2412
* Toplevel function "use" refers to raw ML bootstrap environment,
wenzelm@54449
  2413
without Isar context nor antiquotations.  Potential INCOMPATIBILITY.
wenzelm@54449
  2414
Note that 'ML_file' is the canonical command to load ML files into the
wenzelm@54449
  2415
formal context.
wenzelm@54449
  2416
wenzelm@56205
  2417
* Simplified programming interface to define ML antiquotations, see
wenzelm@56205
  2418
structure ML_Antiquotation.  Minor INCOMPATIBILITY.
wenzelm@56069
  2419
wenzelm@56071
  2420
* ML antiquotation @{here} refers to its source position, which is
wenzelm@56071
  2421
occasionally useful for experimentation and diagnostic purposes.
wenzelm@56071
  2422
wenzelm@56135
  2423
* ML antiquotation @{path} produces a Path.T value, similarly to
wenzelm@56135
  2424
Path.explode, but with compile-time check against the file-system and
wenzelm@56135
  2425
some PIDE markup.  Note that unlike theory source, ML does not have a
wenzelm@56135
  2426
well-defined master directory, so an absolute symbolic path
wenzelm@56135
  2427
specification is usually required, e.g. "~~/src/HOL".
wenzelm@56135
  2428
wenzelm@56399
  2429
* ML antiquotation @{print} inlines a function to print an arbitrary
wenzelm@56399

purposes.

wenzelm@57504
  2437
Isabelle component, e.g. see ProofGeneral-4.2-2 from the Isabelle
wenzelm@57504
  2438
component repository http://isabelle.in.tum.de/components/.  Note that
wenzelm@57504
  2439
the "system" manual provides general explanations about add-on
wenzelm@57504
  2440
components, especially those that are not bundled with the release.
wenzelm@57443
  2441
wenzelm@56439
  2442
* The raw Isabelle process executable has been renamed from
wenzelm@56439
  2443
"isabelle-process" to "isabelle_process", which conforms to common
wenzelm@56439
  2444
shell naming conventions, and allows to define a shell function within
wenzelm@56439
  2445
the Isabelle environment to avoid dynamic path lookup.  Rare
wenzelm@57504
  2446
incompatibility for old tools that do not use the ISABELLE_PROCESS
wenzelm@57504
  2447
settings variable.
wenzelm@56439
  2448
wenzelm@57439
  2449
* Former "isabelle tty" has been superseded by "isabelle console",
wenzelm@57439
  2450
with implicit build like "isabelle jedit", and without the mostly
wenzelm@57439
  2451
obsolete Isar TTY loop.
wenzelm@57439
  2452
wenzelm@57452
  2453
* Simplified "isabelle display" tool.  Settings variables DVI_VIEWER
wenzelm@57452
  2454
and PDF_VIEWER now refer to the actual programs, not shell
wenzelm@57452
  2455
command-lines.  Discontinued option -c: invocation may be asynchronous
wenzelm@57452
  2456
via desktop environment, without any special precautions.  Potential
wenzelm@57452
  2457
INCOMPATIBILITY with ambitious private settings.
wenzelm@57452
  2458
wenzelm@57413
  2459
* Removed obsolete "isabelle unsymbolize".  Note that the usual format
wenzelm@57413
  2460
for email communication is the Unicode rendering of Isabelle symbols,
wenzelm@57413
  2461
as produced by Isabelle/jEdit, for example.
wenzelm@57413
  2462
wenzelm@57452
  2463
* Removed obsolete tool "wwwfind". Similar functionality may be
wenzelm@57452
  2464
integrated into Isabelle/jEdit eventually.
wenzelm@57452
  2465
wenzelm@57452
  2466
* Improved 'display_drafts' concerning desktop integration and
wenzelm@57452
  2467
repeated invocation in PIDE front-end: re-use single file
wenzelm@57452
  2468
$ISABELLE_HOME_USER/tmp/drafts.pdf and corresponding views.
wenzelm@57084
  2469
wenzelm@57452
  2470
* Session ROOT specifications require explicit 'document_files' for
wenzelm@57452
  2471
robust dependencies on LaTeX sources.  Only these explicitly given
wenzelm@57452
  2472
files are copied to the document output directory, before document
wenzelm@57452
  2473
processing is started.
wenzelm@57452
  2474
wenzelm@57504
  2475
* Windows: support for regular TeX installation (e.g. MiKTeX) instead
wenzelm@57504

e.g. non-terminating 'by' steps.
wenzelm@54639
  2487

*** General ***
wenzelm@51293
  2513
wenzelm@53971
  2514
* Discontinued obsolete 'uses' within theory header.  Note that
wenzelm@53971
  2515
commands like 'ML_file' work without separate declaration of file
wenzelm@53971
  2516

'ML_file' in Isabelle2013.  Minor INCOMPATIBILITY.
wenzelm@53971
  2520
wenzelm@53016
  2521
* Simplified subscripts within identifiers, using plain \<^sub>
wenzelm@53016
  2522
instead of the second copy \<^isub> and \<^isup>.  Superscripts are
wenzelm@53016
  2523
only for literal tokens within notation; explicit mixfix annotations
wenzelm@53016
  2524
for consts or fixed variables may be used as fall-back for unusual
wenzelm@53016
  2525
names.  Obsolete \<twosuperior> has been expanded to \<^sup>2 in
wenzelm@53016
  2526
Isabelle/HOL.  INCOMPATIBILITY, use "isabelle update_sub_sup" to
wenzelm@53016
  2527
standardize symbols as a starting point for further manual cleanup.
wenzelm@53016
  2528
The ML reference variable "legacy_isub_isup" may be set as temporary
wenzelm@53016
  2529

  2530
syntax.
wenzelm@53016
  2531
wenzelm@53021
  2532

wenzelm@52487
  2535
* Uniform management of "quick_and_dirty" as system option (see also
wenzelm@52487
  2536
"isabelle options"), configuration option within the context (see also
wenzelm@52487
  2537
Config.get in Isabelle/ML), and attribute in Isabelle/Isar.  Minor
wenzelm@52487
  2538
INCOMPATIBILITY, need to use more official Isabelle means to access
wenzelm@52487
  2539
quick_and_dirty, instead of historical poking into mutable reference.
wenzelm@52059
  2540
wenzelm@52060
  2541
* Renamed command 'print_configs' to 'print_options'.  Minor

  2542
INCOMPATIBILITY.
wenzelm@52060
  2543
wenzelm@52430
  2544
* Proper diagnostic command 'print_state'.  Old 'pr' (with its
wenzelm@52430
  2545
implicit change of some global references) is retained for now as
wenzelm@52430
  2546
control command, e.g. for ProofGeneral 3.7.x.
wenzelm@52430
  2547
wenzelm@52549
  2548
* Discontinued 'print_drafts' command with its old-fashioned PS output
wenzelm@52549
  2549
and Unix command-line print spooling.  Minor INCOMPATIBILITY: use
wenzelm@52549
  2550
'display_drafts' instead and print via the regular document viewer.
wenzelm@52549
  2551
wenzelm@53971
  2552
* Updated and extended "isar-ref" and "implementation" manual,
wenzelm@53971

  2565
(GUI front-end to 'find_theorems' command).
wenzelm@52949
  2566
wenzelm@53050
  2567
* Dockable window "Sledgehammer" manages asynchronous / parallel

  2569
normal editing and checking process.
wenzelm@53050
  2570
wenzelm@51533
  2571
* Dockable window "Timing" provides an overview of relevant command
wenzelm@54332
  2572
timing information, depending on option jedit_timing_threshold.  The
wenzelm@54332
  2573
same timing information is shown in the extended tooltip of the
wenzelm@54332
  2574

wenzelm@53971
  2577
* Improved dockable window "Theories": Continuous checking of proof
wenzelm@53971
  2578
document (visible and required parts) may be controlled explicitly,
wenzelm@53971
  2579
using check box or shortcut "C+e ENTER".  Individual theory nodes may
wenzelm@53971
  2580
be marked explicitly as required and checked in full, using check box
wenzelm@53971
  2581
or shortcut "C+e SPACE".
wenzelm@53971
  2582
wenzelm@54305
  2583
* Improved completion mechanism, which is now managed by the
wenzelm@54305
  2584
Isabelle/jEdit plugin instead of SideKick.  Refined table of Isabelle
wenzelm@54305
  2585
symbol abbreviations (see $ISABELLE_HOME/etc/symbols).
wenzelm@54305
  2586
wenzelm@54319
  2587
* Standard jEdit keyboard shortcut C+b complete-word is remapped to
wenzelm@54319
  2588
isabelle.complete for explicit completion in Isabelle sources.
wenzelm@54319
  2589
INCOMPATIBILITY wrt. jEdit defaults, may have to invent new shortcuts
wenzelm@54319
  2590
to resolve conflict.
wenzelm@54319
  2591
wenzelm@54305
  2592
* Improved support of various "minor modes" for Isabelle NEWS,
wenzelm@54305
  2593
options, session ROOT etc., with completion and SideKick tree view.
wenzelm@54305
  2594
wenzelm@53971
  2595
* Strictly monotonic document update, without premature cancellation of
wenzelm@53971
  2596
running transactions that are still needed: avoid reset/restart of
wenzelm@53971
  2597
such command executions while editing.
wenzelm@53271
  2598
wenzelm@53971
  2599
* Support for asynchronous print functions, as overlay to existing
wenzelm@53971
  2600

wenzelm@53971
  2601
wenzelm@53971
  2602
* Support for automatic tools in HOL, which try to prove or disprove
wenzelm@53971
  2603
toplevel theorem statements.
wenzelm@53971
  2604
wenzelm@53971
  2605
* Action isabelle.reset-font-size resets main text area font size
wenzelm@54365
  2606
according to Isabelle/Scala plugin option "jedit_font_reset_size" (see
wenzelm@54365
  2607
also "Plugin Options / Isabelle / General").  It can be bound to some
wenzelm@54365
  2608
keyboard shortcut by the user (e.g. C+0 and/or C+NUMPAD0).
wenzelm@53971
  2609
wenzelm@53971
  2610
* File specifications in jEdit (e.g. file browser) may refer to
wenzelm@54351
  2611
$ISABELLE_HOME and $ISABELLE_HOME_USER on all platforms.  Discontinued
wenzelm@54351

ballarin@54049
  2623
* Commands 'interpretation' and 'sublocale' are now target-sensitive.
ballarin@54049
  2624
In particular, 'interpretation' allows for non-persistent
ballarin@54049
  2625
interpretation within "context ... begin ... end" blocks offering a
ballarin@54049
  2626
light-weight alternative to 'sublocale'.  See "isar-ref" manual for
ballarin@54049
  2627
details.
haftmann@51747
  2628
ballarin@51565
  2629
* Improved locales diagnostic command 'print_dependencies'.
ballarin@51565
  2630
wenzelm@51313
  2631
* Discontinued obsolete 'axioms' command, which has been marked as
wenzelm@51313
  2632
legacy since Isabelle2009-2.  INCOMPATIBILITY, use 'axiomatization'
wenzelm@51313
  2633
instead, while observing its uniform scope for polymorphism.
wenzelm@51313
  2634
wenzelm@51316
  2635
* Discontinued empty name bindings in 'axiomatization'.
wenzelm@51316
  2636
INCOMPATIBILITY.
wenzelm@51316
  2637
wenzelm@53971
  2638
* System option "proofs" has been discontinued.  Instead the global
wenzelm@53971
  2639
state of Proofterm.proofs is persistently compiled into logic images
wenzelm@53971
  2640
as required, notably HOL-Proofs.  Users no longer need to change
wenzelm@53971
  2641
Proofterm.proofs dynamically.  Minor INCOMPATIBILITY.
wenzelm@53971
  2642
wenzelm@53971
  2643
* Syntax translation functions (print_translation etc.) always depend
wenzelm@53971
  2644
on Proof.context.  Discontinued former "(advanced)" option -- this is
wenzelm@53971
  2645
now the default.  Minor INCOMPATIBILITY.
wenzelm@53971
  2646
wenzelm@53971
  2647
* Former global reference trace_unify_fail is now available as
wenzelm@53971
  2648
configuration option "unify_trace_failure" (global context only).
wenzelm@53971
  2649
wenzelm@52463
  2650
* SELECT_GOAL now retains the syntactic context of the overall goal
wenzelm@52463
  2651
state (schematic variables etc.).  Potential INCOMPATIBILITY in rare
wenzelm@52463
  2652
situations.

*** HOL ***
hoelzl@51002
  2656
wenzelm@54032
  2657
* Stronger precedence of syntax for big intersection and union on
wenzelm@54032
  2658
sets, in accordance with corresponding lattice operations.
wenzelm@54032
  2659
INCOMPATIBILITY.
wenzelm@54032
  2660
wenzelm@54032
  2661
* Notation "{p:A. P}" now allows tuple patterns as well.
wenzelm@54032
  2662
wenzelm@54032
  2663
* Nested case expressions are now translated in a separate check phase
wenzelm@54032
  2664
rather than during parsing. The data for case combinators is separated
wenzelm@54032
  2665
from the datatype package. The declaration attribute
wenzelm@54032
  2666
"case_translation" can be used to register new case combinators:
wenzelm@54032
  2667
wenzelm@54032
  2668
  declare [[case_translation case_combinator constructor1 ... constructorN]]
haftmann@52637
  2669
haftmann@52435
  2670
* Code generator:
wenzelm@53160
  2671
  - 'code_printing' unifies 'code_const' / 'code_type' / 'code_class' /
wenzelm@53160
  2672
    'code_instance'.
wenzelm@53160
  2673
  - 'code_identifier' declares name hints for arbitrary identifiers in
wenzelm@53160
  2674
    generated code, subsuming 'code_modulename'.
wenzelm@53983
  2675
wenzelm@53983
  2676
See the isar-ref manual for syntax diagrams, and the HOL theories for
wenzelm@53983
  2677
examples.
haftmann@52435
  2678
wenzelm@54032
  2679
* Attibute 'code': 'code' now declares concrete and abstract code
wenzelm@54032
  2680
equations uniformly.  Use explicit 'code equation' and 'code abstract'
wenzelm@54032
  2681
to distinguish both when desired.
wenzelm@54032
  2682
wenzelm@54032
  2683
* Discontinued theories Code_Integer and Efficient_Nat by a more
wenzelm@54032
  2684
fine-grain stack of theories Code_Target_Int, Code_Binary_Nat,
wenzelm@54032
  2685
Code_Target_Nat and Code_Target_Numeral.  See the tutorial on code
wenzelm@54032
  2686
generation for details.  INCOMPATIBILITY.
wenzelm@54032
  2687
wenzelm@54032
  2688
* Numeric types are mapped by default to target language numerals:
wenzelm@54032
  2689
natural (replaces former code_numeral) and integer (replaces former
wenzelm@54032
  2690
code_int).  Conversions are available as integer_of_natural /
wenzelm@54032
  2691
natural_of_integer / integer_of_nat / nat_of_integer (in HOL) and
wenzelm@54032
  2692
Code_Numeral.integer_of_natural / Code_Numeral.natural_of_integer (in
wenzelm@54032
  2693
ML).  INCOMPATIBILITY.
wenzelm@54032
  2694
wenzelm@54032
  2695
* Function package: For mutually recursive functions f and g, separate
wenzelm@54032
  2696
cases rules f.cases and g.cases are generated instead of unusable
wenzelm@54032
  2697
f_g.cases which exposed internal sum types. Potential INCOMPATIBILITY,
wenzelm@54032
  2698
in the case that the unusable rule was used nevertheless.
wenzelm@54032
  2699
wenzelm@54032
  2700
* Function package: For each function f, new rules f.elims are
wenzelm@54032
  2701
generated, which eliminate equalities of the form "f x = t".
wenzelm@54032
  2702
wenzelm@54032
  2703
* New command 'fun_cases' derives ad-hoc elimination rules for
wenzelm@54032
  2704
function equations as simplified instances of f.elims, analogous to
wenzelm@54032
  2705
inductive_cases.  See ~~/src/HOL/ex/Fundefs.thy for some examples.

kuncar@54021
  2707
* Lifting:
kuncar@54021
  2708
  - parametrized correspondence relations are now supported:
wenzelm@54378
  2709
    + parametricity theorems for the raw term can be specified in
kuncar@54021
  2710
      the command lift_definition, which allow us to generate stronger
kuncar@54021
  2711
      transfer rules
kuncar@54021
  2712
    + setup_lifting generates stronger transfer rules if parametric
kuncar@54021
  2713
      correspondence relation can be generated
kuncar@54021
  2714
    + various new properties of the relator must be specified to support
kuncar@54021
  2715
      parametricity
kuncar@54021
  2716
    + parametricity theorem for the Quotient relation can be specified
kuncar@54021
  2717
  - setup_lifting generates domain rules for the Transfer package
kuncar@54021
  2718
  - stronger reflexivity prover of respectfulness theorems for type
kuncar@54021
  2719
    copies
kuncar@54021
  2720
  - ===> and --> are now local. The symbols can be introduced
kuncar@54021
  2721
    by interpreting the locale lifting_syntax (typically in an
kuncar@54021
  2722
    anonymous context)
