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

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

* The undocumented feature of implicit cases goal1, goal2, goal3, etc.
wenzelm@60617

global collection of overloaded constant / type definitions into
wenzelm@61269
   399
account. Type definitions with open dependencies on overloaded
wenzelm@61269

haftmann@60517
   518
haftmann@60429

* Former constants Fields.divide (_ / _) and Divides.div (_ div _)
haftmann@60352
   520
are logically unified to Rings.divide in syntactic type class
haftmann@60429
   521
Rings.divide, with infix syntax (_ div _).  Infix syntax (_ / _)
haftmann@60429
   522
for field division is added later as abbreviation in class Fields.inverse.
haftmann@60516
   523
INCOMPATIBILITY,  instantiations must refer to Rings.divide rather
haftmann@60429
   524
than the former separate constants, hence infix syntax (_ / _) is usually
haftmann@60429
   525
not available during instantiation.

'qualified' modifier to restrict name space accesses to the local scope,
wenzelm@59939
   689
as provided by some "context begin ... end" block. For example:

wenzelm@59901
   706
naming policy.
wenzelm@59901
   707
wenzelm@59951
   708
* Command 'notepad' requires proper nesting of begin/end and its proof
wenzelm@59951
   709
structure in the body: 'oops' is no longer supported here. Minor
wenzelm@59951
   710
INCOMPATIBILITY, use 'sorry' instead.
wenzelm@59951
   711
wenzelm@59951
   712
* Command 'named_theorems' declares a dynamic fact within the context,
wenzelm@59951
   713
together with an attribute to maintain the content incrementally. This
wenzelm@59951
   714
supersedes functor Named_Thms in Isabelle/ML, but with a subtle change
wenzelm@59951
   715
of semantics due to external visual order vs. internal reverse order.
wenzelm@59951
   716
wenzelm@59951
   717
* 'find_theorems': search patterns which are abstractions are
wenzelm@59951
   718
schematically expanded before search. Search results match the naive
wenzelm@59951
   719
expectation more closely, particularly wrt. abbreviations.

   720
INCOMPATIBILITY.
wenzelm@59648

wenzelm@59569
   722

theory context.
wenzelm@57941
   724
wenzelm@58928
   725
* Outer syntax commands are managed authentically within the theory
wenzelm@59569
   726
context, without implicit global state. Potential for accidental
wenzelm@58928
   727
INCOMPATIBILITY, make sure that required theories are really imported.
wenzelm@58928

wenzelm@60115
   729
* Historical command-line terminator ";" is no longer accepted (and
wenzelm@60115
   730
already used differently in Isar). Minor INCOMPATIBILITY, use "isabelle
wenzelm@60115
   731
update_semicolons" to remove obsolete semicolons from old theory
wenzelm@60115
   732

wenzelm@59951
   734
* Structural composition of proof methods (meth1; meth2) in Isar

* The Eisbach proof method language allows to define new proof methods
wenzelm@60119
   738
by combining existing ones with their usual syntax. The "match" proof
wenzelm@60119
   739
method provides basic fact/term matching in addition to
wenzelm@60119
   740
premise/conclusion matching through Subgoal.focus, and binds fact names
wenzelm@60288
   741
from matches as well as term patterns within matches. The Isabelle
wenzelm@60288
   742
documentation provides an entry "eisbach" for the Eisbach User Manual.

* Improved folding mode "isabelle" based on Isar syntax. Alternatively,
wenzelm@59569
   749
the "sidekick" mode may be used for document structure.
wenzelm@59569
   750

wenzelm@58758
   754
wenzelm@58540
   755
* Support for BibTeX files: context menu, context-sensitive token
wenzelm@58540
   756
marker, SideKick parser.
wenzelm@58524
   757
wenzelm@58551
   758
* Document antiquotation @{cite} provides formal markup, which is
wenzelm@60265
   759
interpreted semi-formally based on .bib files that happen to be open in
wenzelm@60265
   760
the editor (hyperlinks, completion etc.).
wenzelm@58551
   761
wenzelm@58785
   762
* Less waste of vertical space via negative line spacing (see Global
wenzelm@58785
   763
Options / Text Area).
wenzelm@58785
   764
wenzelm@60089
   765
* Improved graphview panel with optional output of PNG or PDF, for
wenzelm@60273
   766
display of 'thy_deps', 'class_deps' etc.
wenzelm@60009
   767
wenzelm@60115
   768
* The commands 'thy_deps' and 'class_deps' allow optional bounds to
wenzelm@60115
   769
restrict the visualized hierarchy.
wenzelm@60093
   770
wenzelm@60072
   771
* Improved scheduling for asynchronous print commands (e.g. provers
wenzelm@60072

*** Document preparation ***
wenzelm@59951
   776

   777
* Document markup commands 'chapter', 'section', 'subsection',
wenzelm@59951
   778
'subsubsection', 'text', 'txt', 'text_raw' work uniformly in any
wenzelm@59951
   779
context, even before the initial 'theory' command. Obsolete proof
wenzelm@59951
   780
commands 'sect', 'subsect', 'subsubsect', 'txt_raw' have been
wenzelm@59951
   781
discontinued, use 'section', 'subsection', 'subsubsection', 'text_raw'
wenzelm@59951
   782
instead. The old 'header' command is still retained for some time, but
wenzelm@59951
   783
should be replaced by 'chapter', 'section' etc. (using "isabelle
wenzelm@59951
   784
update_header"). Minor INCOMPATIBILITY.
wenzelm@59951
   785
wenzelm@60009
   786
* Official support for "tt" style variants, via \isatt{...} or
wenzelm@60009
   787
\begin{isabellett}...\end{isabellett}. The somewhat fragile \verb or
wenzelm@60009
   788
verbatim environment of LaTeX is no longer used. This allows @{ML} etc.
wenzelm@60009
   789
as argument to other macros (such as footnotes).
wenzelm@60009
   790
wenzelm@60009
   791
* Document antiquotation @{verbatim} prints ASCII text literally in "tt"
wenzelm@60009
   792
style.
wenzelm@60009
   793
wenzelm@60009
   794
* Discontinued obsolete option "document_graph": session_graph.pdf is
wenzelm@60009
   795
produced unconditionally for HTML browser_info and PDF-LaTeX document.
wenzelm@60009
   796
wenzelm@59951
   797
* Diagnostic commands and document markup commands within a proof do not
wenzelm@59951
   798
affect the command tag for output. Thus commands like 'thm' are subject
wenzelm@59951
   799
to proof document structure, and no longer "stick out" accidentally.
wenzelm@59951
   800
Commands 'text' and 'txt' merely differ in the LaTeX style, not their
wenzelm@59951
   801
tags. Potential INCOMPATIBILITY in exotic situations.
wenzelm@59951
   802
wenzelm@59951
   803
* System option "pretty_margin" is superseded by "thy_output_margin",
wenzelm@59951
   804
which is also accessible via document antiquotation option "margin".
wenzelm@59951
   805
Only the margin for document output may be changed, but not the global
wenzelm@59951
   806
pretty printing: that is 76 for plain console output, and adapted
wenzelm@59951
   807
dynamically in GUI front-ends. Implementations of document
wenzelm@59951
   808
antiquotations need to observe the margin explicitly according to
wenzelm@59951
   809
Thy_Output.string_of_margin. Minor INCOMPATIBILITY.
wenzelm@59951
   810
wenzelm@60299
   811
* Specification of 'document_files' in the session ROOT file is
wenzelm@60299
   812
mandatory for document preparation. The legacy mode with implicit
wenzelm@60299

* Proof methods with explicit instantiation ("rule_tac", "subgoal_tac"
wenzelm@59835
   820
etc.) allow an optional context of local variables ('for' declaration):
wenzelm@59835
   821
these variables become schematic in the instantiated theorem; this
wenzelm@59835
   822
behaviour is analogous to 'for' in attributes "where" and "of".
wenzelm@59835
   823
Configuration option rule_insts_schematic (default false) controls use
wenzelm@59835
   824
of schematic variables outside the context. Minor INCOMPATIBILITY,
wenzelm@59835
   825
declare rule_insts_schematic = true temporarily and update to use local

   828
* Explicit instantiation via attributes "where", "of", and proof methods
wenzelm@60009
   829
"rule_tac" with derivatives like "subgoal_tac" etc. admit dummy patterns

* Lexical separation of signed and unsigned numerals: categories "num"
wenzelm@60010
   838
and "float" are unsigned. INCOMPATIBILITY: subtle change in precedence
wenzelm@60010
   839

blanchet@57983
   917
blanchet@59039

  - Fixed soundness bug related to the strict and non-strict subset
blanchet@59039
   920

blanchet@59039
   921
blanchet@57737
   922
* Sledgehammer:
blanchet@59511
   923
  - CVC4 is now included with Isabelle instead of CVC3 and run by
blanchet@59511
   924
    default.
blanchet@59965
   925
  - Z3 is now always enabled by default, now that it is fully open
blanchet@59965
   926
    source. The "z3_non_commercial" option is discontinued.
blanchet@57737

  - Minimization is now always enabled by default.
wenzelm@60010
   928
    Removed sub-command:

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

   932
  - Improved support for CVC4 and veriT.
blanchet@57737
   933
blanchet@58062
   934
* Old and new SMT modules:
blanchet@58067
   935
  - The old 'smt' method has been renamed 'old_smt' and moved to
wenzelm@59569
   936
    'src/HOL/Library/Old_SMT.thy'. It is provided for compatibility,
wenzelm@59569
   937
    until applications have been ported to use the new 'smt' method. For
wenzelm@59569
   938
    the method to work, an older version of Z3 (e.g. Z3 3.2 or 4.0) must
wenzelm@59569
   939
    be installed, and the environment variable "OLD_Z3_SOLVER" must
wenzelm@59569
   940
    point to it.
blanchet@58062
   941
    INCOMPATIBILITY.

    INCOMPATIBILITY.
wenzelm@59569
   944

   945
    reconstruction time of Z3 proof steps in the new 'smt' method.
boehmes@59216
   946
  - New option 'smt_statistics' to display statistics of the new 'smt'
boehmes@59216
   947
    method, especially runtime statistics of Z3 proof reconstruction.
blanchet@58060
   948
wenzelm@60261
   949
* Lifting: command 'lift_definition' allows to execute lifted constants
wenzelm@60261
   950
that have as a return type a datatype containing a subtype. This
wenzelm@60261
   951
overcomes long-time limitations in the area of code generation and
wenzelm@60261
   952
lifting, and avoids tedious workarounds.
kuncar@60258
   953
wenzelm@60009
   954
* Command and antiquotation "value" provide different evaluation slots
wenzelm@60009

   956
Minor INCOMPATIBILITY.
wenzelm@60009
   957
wenzelm@60009
   958
* Add NO_MATCH-simproc, allows to check for syntactic non-equality.
wenzelm@60009
   959
wenzelm@60009
   960
* field_simps: Use NO_MATCH-simproc for distribution rules, to avoid
wenzelm@60009
   961
non-termination in case of distributing a division. With this change
wenzelm@60009
   962
field_simps is in some cases slightly less powerful, if it fails try to
wenzelm@60009
   963
add algebra_simps, or use divide_simps. Minor INCOMPATIBILITY.
wenzelm@60009
   964
wenzelm@60009
   965
* Separate class no_zero_divisors has been given up in favour of fully
wenzelm@60009
   966
algebraic semiring_no_zero_divisors. INCOMPATIBILITY.
wenzelm@60009
   967
wenzelm@60009

wenzelm@60009
   969
INCOMPATIBILITY.
wenzelm@60009
   970
wenzelm@60009
   971
* Classes division_ring, field and linordered_field always demand
wenzelm@60009
   972
"inverse 0 = 0". Given up separate classes division_ring_inverse_zero,
wenzelm@60009
   973
field_inverse_zero and linordered_field_inverse_zero. INCOMPATIBILITY.
wenzelm@60009
   974
wenzelm@60009
   975

   976
additive inverse operation. INCOMPATIBILITY.
wenzelm@60009
   977
lp15@60020
   978
* Complex powers and square roots. The functions "ln" and "powr" are now

INCOMPATIBILITY: type constraints may be necessary.
lp15@60020
   981
wenzelm@60009
   982
* The functions "sin" and "cos" are now defined for any type of sort
wenzelm@60009
   983
"{real_normed_algebra_1,banach}" type, so in particular on "real" and
wenzelm@60009
   984
"complex" uniformly. Minor INCOMPATIBILITY: type constraints may be
wenzelm@60009
   985
needed.
wenzelm@60009
   986
wenzelm@60009
   987
* New library of properties of the complex transcendental functions sin,
wenzelm@60009
   988
cos, tan, exp, Ln, Arctan, Arcsin, Arccos. Ported from HOL Light.
wenzelm@60009
   989
wenzelm@60009
   990
* The factorial function, "fact", now has type "nat => 'a" (of a sort
wenzelm@60009
   991
that admits numeric types including nat, int, real and complex.
wenzelm@60009
   992
INCOMPATIBILITY: an expression such as "fact 3 = 6" may require a type
wenzelm@60009
   993
constraint, and the combination "real (fact k)" is likely to be
wenzelm@60009
   994
unsatisfactory. If a type conversion is still necessary, then use
wenzelm@60009
   995
"of_nat (fact k)" or "real_of_nat (fact k)".
wenzelm@60009
   996
wenzelm@60009
   997
* Removed functions "natfloor" and "natceiling", use "nat o floor" and
wenzelm@60009
   998
"nat o ceiling" instead. A few of the lemmas have been retained and
wenzelm@60009
   999
adapted: in their names "natfloor"/"natceiling" has been replaced by
wenzelm@60009
  1000
"nat_floor"/"nat_ceiling".
wenzelm@60009
  1001
wenzelm@60009
  1002
* Qualified some duplicated fact names required for boostrapping the
wenzelm@60009
  1003
type class hierarchy:

wenzelm@60009
  1005
  field_inverse_zero ~> inverse_zero

wenzelm@60009
  1008
Minor INCOMPATIBILITY.
wenzelm@60009
  1009
wenzelm@60009
  1010
* Eliminated fact duplicates:
wenzelm@60009
  1011
  mult_less_imp_less_right ~> mult_right_less_imp_less
wenzelm@60009
  1012
  mult_less_imp_less_left ~> mult_left_less_imp_less

  1013
Minor INCOMPATIBILITY.
wenzelm@60009
  1014
wenzelm@60009
  1015
* Fact consolidation: even_less_0_iff is subsumed by
wenzelm@60009
  1016
double_add_less_zero_iff_single_add_less_zero (simp by default anyway).
wenzelm@60009
  1017
wenzelm@60009
  1018
* Generalized and consolidated some theorems concerning divsibility:
wenzelm@60009

  dvd_reduce ~> dvd_add_triv_right_iff
wenzelm@60009
  1020
  dvd_plus_eq_right ~> dvd_add_right_iff
wenzelm@60009

wenzelm@60009
  1022
Minor INCOMPATIBILITY.
wenzelm@60009

  even_def ~> even_iff_mod_2_eq_zero
wenzelm@60009
  1027
INCOMPATIBILITY.
wenzelm@60009

wenzelm@60009
  1030
INCOMPATIBILITY.
wenzelm@60009
  1031
wenzelm@60009
  1032
* Bootstrap of listsum as special case of abstract product over lists.
wenzelm@60009
  1033
Fact rename:
wenzelm@60009
  1034
    listsum_def ~> listsum.eq_foldr
wenzelm@60009
  1035
INCOMPATIBILITY.
wenzelm@60009
  1036
wenzelm@60009
  1037
* Product over lists via constant "listprod".
wenzelm@60009
  1038
wenzelm@60009

  1043
generated code in target languages in HOL/Library/Code_Test. See
wenzelm@59569
  1044

  1045
wenzelm@60009
  1046
* Library/Multiset:
blanchet@59813
  1047
  - Introduced "replicate_mset" operation.
blanchet@59813
  1048
  - Introduced alternative characterizations of the multiset ordering in
blanchet@59813
  1049
    "Library/Multiset_Order".
blanchet@59958

    INCOMPATIBILITY.
blanchet@59813

  1101
* Subtle change of name space policy: undeclared entries are now
wenzelm@60009
  1102
considered inaccessible, instead of accessible via the fully-qualified
wenzelm@60009
  1103
internal name. This mainly affects Name_Space.intern (and derivatives),
wenzelm@60009
  1104
which may produce an unexpected Long_Name.hidden prefix. Note that
wenzelm@60010
  1105
contemporary applications use the strict Name_Space.check (and
wenzelm@60009
  1106

INCOMPATIBILITY in rare applications of Name_Space.intern.

wenzelm@59951
  1118
* Former combinators NAMED_CRITICAL and CRITICAL for central critical

wenzelm@59951
  1120
Multithreading.synchronized and its high-level derivative
wenzelm@59951
  1121
Synchronized.var (which is usually sufficient in applications). Subtle
wenzelm@59951

  1123
nested.
wenzelm@59951
  1124
wenzelm@60009
  1125
* Synchronized.value (ML) is actually synchronized (as in Scala): subtle

  1126
change of semantics with minimal potential for INCOMPATIBILITY.
wenzelm@59899
  1127
wenzelm@59621
  1128
* The main operations to certify logical entities are Thm.ctyp_of and

wenzelm@59564
  1144
* Goal.prove_multi is superseded by the fully general Goal.prove_common,

  1145
which also allows to specify a fork priority.
wenzelm@59564
  1146
wenzelm@59936

* Discontinued old-fashioned "codegen" tool. Code generation can always
wenzelm@59951

be externally triggered using an appropriate ROOT file plus a
wenzelm@59951
  1164

wenzelm@57452
  1185
* Support for official Standard ML within the Isabelle context.
wenzelm@57452
  1186
Command 'SML_file' reads and evaluates the given Standard ML file.
wenzelm@57452
  1187
Toplevel bindings are stored within the theory context; the initial
wenzelm@57452
  1188
environment is restricted to the Standard ML implementation of
wenzelm@57452
  1189
Poly/ML, without the add-ons of Isabelle/ML.  Commands 'SML_import'
wenzelm@57452
  1190
and 'SML_export' allow to exchange toplevel bindings between the two
wenzelm@57452
  1191
separate environments.  See also ~~/src/Tools/SML/Examples.thy for
wenzelm@57452
  1192
some examples.
wenzelm@56499
  1193
wenzelm@57504
  1194
* Standard tactics and proof methods such as "clarsimp", "auto" and
wenzelm@57504
  1195
"safe" now preserve equality hypotheses "x = expr" where x is a free
wenzelm@57504
  1196
variable.  Locale assumptions and chained facts containing "x"
wenzelm@57504
  1197
continue to be useful.  The new method "hypsubst_thin" and the
wenzelm@57504
  1198
configuration option "hypsubst_thin" (within the attribute name space)
wenzelm@57504
  1199
restore the previous behavior.  INCOMPATIBILITY, especially where
wenzelm@57504
  1200
induction is done after these methods or when the names of free and
wenzelm@57504
  1201
bound variables clash.  As first approximation, old proofs may be
wenzelm@57504
  1202
repaired by "using [[hypsubst_thin = true]]" in the critical spot.
wenzelm@57504
  1203
wenzelm@56232
  1204
* More static checking of proof methods, which allows the system to
wenzelm@56232
  1205
form a closure over the concrete syntax.  Method arguments should be
wenzelm@56232
  1206
processed in the original proof context as far as possible, before
wenzelm@56232
  1207
operating on the goal state.  In any case, the standard discipline for
wenzelm@56232
  1208
subgoal-addressing needs to be observed: no subgoals or a subgoal
wenzelm@56232
  1209
number that is out of range produces an empty result sequence, not an
wenzelm@56232
  1210
exception.  Potential INCOMPATIBILITY for non-conformant tactical
wenzelm@56232
  1211
proof tools.
wenzelm@56232
  1212
wenzelm@57452
  1213
* Lexical syntax (inner and outer) supports text cartouches with
wenzelm@57452
  1214
arbitrary nesting, and without escapes of quotes etc.  The Prover IDE
wenzelm@57452
  1215
supports input via ` (backquote).
wenzelm@57452
  1216
wenzelm@57452
  1217
* The outer syntax categories "text" (for formal comments and document
wenzelm@57452
  1218
markup commands) and "altstring" (for literal fact references) allow
wenzelm@57452
  1219
cartouches as well, in addition to the traditional mix of quotations.
wenzelm@57452
  1220
wenzelm@57452
  1221
* Syntax of document antiquotation @{rail} now uses \<newline> instead
wenzelm@57452
  1222
of "\\", to avoid the optical illusion of escaped backslash within
wenzelm@57491
  1223
string token.  General renovation of its syntax using text cartouches.
wenzelm@57452
  1224
Minor INCOMPATIBILITY.
wenzelm@57452
  1225
wenzelm@57452
  1226
* Discontinued legacy_isub_isup, which was a temporary workaround for
wenzelm@57452
  1227
Isabelle/ML in Isabelle2013-1.  The prover process no longer accepts
wenzelm@57452
  1228
old identifier syntax with \<^isub> or \<^isup>.  Potential
wenzelm@57452
  1229
INCOMPATIBILITY.
wenzelm@57452
  1230
wenzelm@57452
  1231
* Document antiquotation @{url} produces markup for the given URL,
wenzelm@57452
  1232
which results in an active hyperlink within the text.
wenzelm@57452
  1233
wenzelm@57452
  1234
* Document antiquotation @{file_unchecked} is like @{file}, but does
wenzelm@57452
  1235
not check existence within the file-system.
wenzelm@57452
  1236
wenzelm@57452
  1237
* Updated and extended manuals: codegen, datatypes, implementation,
wenzelm@57452

  1248
to PIDE hyperlinks.
wenzelm@57452
  1249
wenzelm@57452
  1250
* Auxiliary files ('ML_file' etc.) are managed by the Prover IDE.
wenzelm@57452
  1251
Open text buffers take precedence over copies within the file-system.
wenzelm@57452
  1252
wenzelm@57452

  1254
auxiliary ML files.
wenzelm@57423
  1255
wenzelm@57423
  1256
* Improved syntactic and semantic completion mechanism, with simple
wenzelm@57423
  1257
templates, completion language context, name-space completion,
wenzelm@57423
  1258
file-name completion, spell-checker completion.
wenzelm@57423
  1259
wenzelm@57423
  1260
* Refined GUI popup for completion: more robust key/mouse event
wenzelm@57423
  1261
handling and propagation to enclosing text area -- avoid loosing
wenzelm@57423
  1262
keystrokes with slow / remote graphics displays.
wenzelm@57423
  1263
wenzelm@57833
  1264
* Completion popup supports both ENTER and TAB (default) to select an
wenzelm@57833
  1265
item, depending on Isabelle options.
wenzelm@57833
  1266
wenzelm@57423
  1267
* Refined insertion of completion items wrt. jEdit text: multiple
wenzelm@57423
  1268
selections, rectangular selections, rectangular selection as "tall
wenzelm@57423
  1269
caret".
wenzelm@56342
  1270
wenzelm@56580
  1271
* Integrated spell-checker for document text, comments etc. with
wenzelm@57423
  1272
completion popup and context-menu.
wenzelm@56554
  1273
wenzelm@56879
  1274
* More general "Query" panel supersedes "Find" panel, with GUI access
wenzelm@56879
  1275
to commands 'find_theorems' and 'find_consts', as well as print
wenzelm@56879
  1276
operations for the context.  Minor incompatibility in keyboard
wenzelm@56879
  1277
shortcuts etc.: replace action isabelle-find by isabelle-query.
wenzelm@56761
  1278
wenzelm@56901
  1279
* Search field for all output panels ("Output", "Query", "Info" etc.)
wenzelm@56901
  1280
to highlight text via regular expression.
wenzelm@56901
  1281
wenzelm@54881
  1282
* Option "jedit_print_mode" (see also "Plugin Options / Isabelle /
wenzelm@54881
  1283
General") allows to specify additional print modes for the prover
wenzelm@54881
  1284
process, without requiring old-fashioned command-line invocation of
wenzelm@54881
  1285
"isabelle jedit -m MODE".
wenzelm@54881
  1286
wenzelm@56505
  1287
* More support for remote files (e.g. http) using standard Java
wenzelm@56505
  1288
networking operations instead of jEdit virtual file-systems.
wenzelm@56505
  1289
wenzelm@57822
  1290
* Empty editors buffers that are no longer required (e.g.\ via theory
wenzelm@57822
  1291
imports) are automatically removed from the document model.
wenzelm@57822
  1292
wenzelm@57869
  1293
* Improved monitor panel.
wenzelm@57869
  1294
wenzelm@56838
  1295
* Improved Console/Scala plugin: more uniform scala.Console output,
wenzelm@56838
  1296
more robust treatment of threads and interrupts.
wenzelm@56838
  1297
wenzelm@56939
  1298
* Improved management of dockable windows: clarified keyboard focus
wenzelm@56939
  1299
and window placement wrt. main editor view; optional menu item to
wenzelm@56939
  1300
"Detach" a copy where this makes sense.
wenzelm@56939
  1301
wenzelm@57452
  1302
* New Simplifier Trace panel provides an interactive view of the
wenzelm@57591
  1303

* Low-level type-class commands 'classes', 'classrel', 'arities' have
wenzelm@57504
  1310
been discontinued to avoid the danger of non-trivial axiomatization
wenzelm@57504
  1311
that is not immediately visible.  INCOMPATIBILITY, use regular
wenzelm@57504
  1312
'instance' command with proof.  The required OFCLASS(...) theorem
wenzelm@57504
  1313
might be postulated via 'axiomatization' beforehand, or the proof
wenzelm@57504
  1314
finished trivially if the underlying class definition is made vacuous
wenzelm@57504
  1315
(without any assumptions).  See also Isabelle/ML operations

* Basic constants of Pure use more conventional names and are always
wenzelm@56245
  1320
qualified.  Rare INCOMPATIBILITY, but with potentially serious
wenzelm@56245
  1321
consequences, notably for tools in Isabelle/ML.  The following
wenzelm@56245
  1322
renaming needs to be applied:
wenzelm@56245
  1323
wenzelm@56245
  1324
  ==             ~>  Pure.eq
wenzelm@56245
  1325
  ==>            ~>  Pure.imp
wenzelm@56245
  1326
  all            ~>  Pure.all
wenzelm@56245
  1327
  TYPE           ~>  Pure.type
wenzelm@56245
  1328
  dummy_pattern  ~>  Pure.dummy_pattern
wenzelm@56245
  1329
wenzelm@56245
  1330
Systematic porting works by using the following theory setup on a
wenzelm@56245
  1331
*previous* Isabelle version to introduce the new name accesses for the
wenzelm@56245
  1332
old constants:
wenzelm@56245
  1333
wenzelm@56245
  1334
setup {*
wenzelm@56245
  1335
  fn thy => thy
wenzelm@56245
  1336
    |> Sign.root_path
wenzelm@56245
  1337
    |> Sign.const_alias (Binding.qualify true "Pure" @{binding eq}) "=="
wenzelm@56245
  1338
    |> Sign.const_alias (Binding.qualify true "Pure" @{binding imp}) "==>"
wenzelm@56245
  1339
    |> Sign.const_alias (Binding.qualify true "Pure" @{binding all}) "all"
wenzelm@56245
  1340
    |> Sign.restore_naming thy
wenzelm@56245
  1341
*}
wenzelm@56245
  1342
wenzelm@56245
  1343
Thus ML antiquotations like @{const_name Pure.eq} may be used already.
wenzelm@56245
  1344
Later the application is moved to the current Isabelle version, and
wenzelm@56245
  1345
the auxiliary aliases are deleted.
wenzelm@56245

wenzelm@55143
  1347
* Attributes "where" and "of" allow an optional context of local
wenzelm@55143
  1348
variables ('for' declaration): these variables become schematic in the
wenzelm@55143
  1349
instantiated theorem.
wenzelm@55143
  1350
wenzelm@55152
  1351
* Obsolete attribute "standard" has been discontinued (legacy since
wenzelm@55152
  1352
Isabelle2012).  Potential INCOMPATIBILITY, use explicit 'for' context
wenzelm@55152
  1353
where instantiations with schematic variables are intended (for
wenzelm@55152
  1354
declaration commands like 'lemmas' or attributes like "of").  The
wenzelm@55152
  1355
following temporary definition may help to port old applications:
wenzelm@55152
  1356
wenzelm@55152
  1357
  attribute_setup standard =
wenzelm@55152
  1358

wenzelm@55152
  1359
wenzelm@55001
  1360
* More thorough check of proof context for goal statements and
wenzelm@55006
  1361
attributed fact expressions (concerning background theory, declared
wenzelm@55006
  1362
hyps).  Potential INCOMPATIBILITY, tools need to observe standard
wenzelm@55006
  1363
context discipline.  See also Assumption.add_assumes and the more

  1364
primitive Thm.assume_hyps.
wenzelm@55001
  1365
wenzelm@55108
  1366
* Inner syntax token language allows regular quoted strings "..."
wenzelm@55108
  1367
(only makes sense in practice, if outer syntax is delimited
wenzelm@57452
  1368
differently, e.g. via cartouches).
wenzelm@57452
  1369
wenzelm@57504
  1370
* Command 'print_term_bindings' supersedes 'print_binds' for clarity,
wenzelm@57504
  1371
but the latter is retained some time as Proof General legacy.
wenzelm@57504
  1372
wenzelm@57452
  1373

* New internal SAT solver "cdclite" that produces models and proof
wenzelm@57508
  1569
traces.  This solver replaces the internal SAT solvers "enumerate" and
wenzelm@57508
  1570
"dpll".  Applications that explicitly used one of these two SAT
wenzelm@57508
  1571
solvers should use "cdclite" instead. In addition, "cdclite" is now
wenzelm@57508
  1572
the default SAT solver for the "sat" and "satx" proof methods and
wenzelm@57508
  1573
corresponding tactics; the old default can be restored using "declare

* SMT module: A new version of the SMT module, temporarily called
wenzelm@57508
  1577
"SMT2", uses SMT-LIB 2 and supports recent versions of Z3 (e.g.,
wenzelm@57508
  1578
4.3). The new proof method is called "smt2". CVC3 and CVC4 are also
wenzelm@57508
  1579
supported as oracles. Yices is no longer supported, because no version
wenzelm@57508
  1580
of the solver can handle both SMT-LIB 2 and quantifiers.
wenzelm@57508
  1581
wenzelm@57508

blanchet@57532
  1590
    . New SML-based learning algorithms eliminate the dependency on
wenzelm@57508
  1591
      Python and increase performance and reliability.
wenzelm@57508
  1592
    . MaSh and MeSh are now used by default together with the
wenzelm@57508
  1593
      traditional MePo (Meng-Paulson) relevance filter. To disable
wenzelm@57508
  1594
      MaSh, set the "MaSh" system option in Isabelle/jEdit Plugin
wenzelm@57508

  1850
haftmann@54230
  1851
a) Arbitrary failing proof not involving "diff_def":

  1852
Consider simplification with algebra_simps or field_simps.
haftmann@54230
  1853
haftmann@54230

Try with "using <rule for addition> of [... "- _" ...]" by simp".
haftmann@54230
  1856
haftmann@54230
  1857
c) Simplification with "diff_def": just drop "diff_def".

  1858
Consider simplification with algebra_simps or field_simps;

"simp add: diff_conv_add_uminus del: add_uminus_conv_diff".

* The signature and semantics of Document.Snapshot.cumulate_markup /
wenzelm@55622
  2162
select_markup have been clarified.  Markup is now traversed in the
wenzelm@55622
  2163
order of reports given by the prover: later markup is usually more
wenzelm@55622
  2164
specific and may override results accumulated so far.  The elements
wenzelm@55622
  2165
guard is mandatory and checked precisely.  Subtle INCOMPATIBILITY.

wenzelm@54449
  2172
wenzelm@57504
  2173
* Subtle change of semantics of Thm.eq_thm: theory stamps are not
wenzelm@57504
  2174
compared (according to Thm.thm_ord), but assumed to be covered by the
wenzelm@57504
  2175
current background theory.  Thus equivalent data produced in different
wenzelm@57504
  2176
branches of the theory graph usually coincides (e.g. relevant for
wenzelm@57504
  2177
theory merge).  Note that the softer Thm.eq_thm_prop is often more
wenzelm@57504
  2178
appropriate than Thm.eq_thm.
wenzelm@57504
  2179
wenzelm@57504
  2180
* Proper context for basic Simplifier operations: rewrite_rule,
wenzelm@57504
  2181
rewrite_goals_rule, rewrite_goals_tac etc. INCOMPATIBILITY, need to
wenzelm@57504
  2182
pass runtime Proof.context (and ensure that the simplified entity
wenzelm@57504
  2183
actually belongs to it).
wenzelm@57504
  2184
wenzelm@57504
  2185
* Proper context discipline for read_instantiate and instantiate_tac:
wenzelm@57504
  2186
variables that are meant to become schematic need to be given as
wenzelm@57504
  2187
fixed, and are generalized by the explicit context of local variables.
wenzelm@57504
  2188
This corresponds to Isar attributes "where" and "of" with 'for'
wenzelm@57504
  2189
declaration.  INCOMPATIBILITY, also due to potential change of indices
wenzelm@57504
  2190
of schematic variables.
wenzelm@57504
  2191
wenzelm@56303
  2192
* Moved ML_Compiler.exn_trace and other operations on exceptions to

  2193
structure Runtime.  Minor INCOMPATIBILITY.
wenzelm@56303
  2194
wenzelm@56279
  2195
* Discontinued old Toplevel.debug in favour of system option
wenzelm@57452
  2196
"ML_exception_trace", which may be also declared within the context
wenzelm@57452
  2197
via "declare [[ML_exception_trace = true]]".  Minor INCOMPATIBILITY.
wenzelm@56279
  2198
wenzelm@56281
  2199
* Renamed configuration option "ML_trace" to "ML_source_trace". Minor
wenzelm@56281
  2200
INCOMPATIBILITY.
wenzelm@56281
  2201
wenzelm@56281
  2202
* Configuration option "ML_print_depth" controls the pretty-printing
wenzelm@56281
  2203
depth of the ML compiler within the context.  The old print_depth in
wenzelm@56285
  2204
ML is still available as default_print_depth, but rarely used.  Minor
wenzelm@56285
  2205
INCOMPATIBILITY.
wenzelm@56279
  2206
wenzelm@54449
  2207
* Toplevel function "use" refers to raw ML bootstrap environment,
wenzelm@54449
  2208
without Isar context nor antiquotations.  Potential INCOMPATIBILITY.
wenzelm@54449
  2209
Note that 'ML_file' is the canonical command to load ML files into the
wenzelm@54449
  2210
formal context.
wenzelm@54449
  2211
wenzelm@56205
  2212
* Simplified programming interface to define ML antiquotations, see
wenzelm@56205
  2213
structure ML_Antiquotation.  Minor INCOMPATIBILITY.
wenzelm@56069
  2214
wenzelm@56071
  2215
* ML antiquotation @{here} refers to its source position, which is
wenzelm@56071
  2216
occasionally useful for experimentation and diagnostic purposes.
wenzelm@56071
  2217
wenzelm@56135
  2218
* ML antiquotation @{path} produces a Path.T value, similarly to
wenzelm@56135
  2219
Path.explode, but with compile-time check against the file-system and
wenzelm@56135
  2220
some PIDE markup.  Note that unlike theory source, ML does not have a
wenzelm@56135
  2221
well-defined master directory, so an absolute symbolic path
wenzelm@56135
  2222
specification is usually required, e.g. "~~/src/HOL".
wenzelm@56135
  2223
wenzelm@56399
  2224
* ML antiquotation @{print} inlines a function to print an arbitrary
wenzelm@56399
  2225
ML value, which is occasionally useful for diagnostic or demonstration
wenzelm@56399
  2226
purposes.

  2232
Isabelle component, e.g. see ProofGeneral-4.2-2 from the Isabelle
wenzelm@57504
  2233
component repository http://isabelle.in.tum.de/components/.  Note that
wenzelm@57504
  2234
the "system" manual provides general explanations about add-on
wenzelm@57504
  2235
components, especially those that are not bundled with the release.
wenzelm@57443
  2236
wenzelm@56439
  2237
* The raw Isabelle process executable has been renamed from
wenzelm@56439
  2238
"isabelle-process" to "isabelle_process", which conforms to common
wenzelm@56439
  2239
shell naming conventions, and allows to define a shell function within
wenzelm@56439
  2240
the Isabelle environment to avoid dynamic path lookup.  Rare
wenzelm@57504
  2241
incompatibility for old tools that do not use the ISABELLE_PROCESS
wenzelm@57504
  2242
settings variable.
wenzelm@56439
  2243
wenzelm@57439
  2244
* Former "isabelle tty" has been superseded by "isabelle console",
wenzelm@57439
  2245
with implicit build like "isabelle jedit", and without the mostly
wenzelm@57439
  2246
obsolete Isar TTY loop.
wenzelm@57439
  2247
wenzelm@57452
  2248
* Simplified "isabelle display" tool.  Settings variables DVI_VIEWER
wenzelm@57452
  2249
and PDF_VIEWER now refer to the actual programs, not shell
wenzelm@57452
  2250
command-lines.  Discontinued option -c: invocation may be asynchronous
wenzelm@57452
  2251
via desktop environment, without any special precautions.  Potential
wenzelm@57452
  2252
INCOMPATIBILITY with ambitious private settings.
wenzelm@57452
  2253
wenzelm@57413
  2254
* Removed obsolete "isabelle unsymbolize".  Note that the usual format
wenzelm@57413
  2255
for email communication is the Unicode rendering of Isabelle symbols,
wenzelm@57413
  2256
as produced by Isabelle/jEdit, for example.
wenzelm@57413
  2257
wenzelm@57452
  2258
* Removed obsolete tool "wwwfind". Similar functionality may be
wenzelm@57452
  2259
integrated into Isabelle/jEdit eventually.
wenzelm@57452
  2260
wenzelm@57452
  2261
* Improved 'display_drafts' concerning desktop integration and
wenzelm@57452
  2262
repeated invocation in PIDE front-end: re-use single file
wenzelm@57452
  2263
$ISABELLE_HOME_USER/tmp/drafts.pdf and corresponding views.
wenzelm@57084
  2264
wenzelm@57452
  2265
* Session ROOT specifications require explicit 'document_files' for
wenzelm@57452
  2266
robust dependencies on LaTeX sources.  Only these explicitly given
wenzelm@57452
  2267
files are copied to the document output directory, before document
wenzelm@57452
  2268
processing is started.
wenzelm@57452
  2269
wenzelm@57504
  2270
* Windows: support for regular TeX installation (e.g. MiKTeX) instead
wenzelm@57504

e.g. non-terminating 'by' steps.
wenzelm@54639
  2282

  2285
wenzelm@54648

*** General ***
wenzelm@51293
  2308
wenzelm@53971
  2309
* Discontinued obsolete 'uses' within theory header.  Note that
wenzelm@53971
  2310
commands like 'ML_file' work without separate declaration of file
wenzelm@53971
  2311

'ML_file' in Isabelle2013.  Minor INCOMPATIBILITY.
wenzelm@53971
  2315
wenzelm@53016

* Simplified subscripts within identifiers, using plain \<^sub>
wenzelm@53016
  2317
instead of the second copy \<^isub> and \<^isup>.  Superscripts are
wenzelm@53016
  2318
only for literal tokens within notation; explicit mixfix annotations
wenzelm@53016
  2319
for consts or fixed variables may be used as fall-back for unusual

  2320
names.  Obsolete \<twosuperior> has been expanded to \<^sup>2 in
wenzelm@53016
  2321
Isabelle/HOL.  INCOMPATIBILITY, use "isabelle update_sub_sup" to
wenzelm@53016
  2322
standardize symbols as a starting point for further manual cleanup.
wenzelm@53016
  2323
The ML reference variable "legacy_isub_isup" may be set as temporary
wenzelm@53016
  2324

  2325
syntax.

  2326
wenzelm@53021
  2327

* Uniform management of "quick_and_dirty" as system option (see also
wenzelm@52487
  2331
"isabelle options"), configuration option within the context (see also
wenzelm@52487
  2332
Config.get in Isabelle/ML), and attribute in Isabelle/Isar.  Minor
wenzelm@52487
  2333
INCOMPATIBILITY, need to use more official Isabelle means to access
wenzelm@52487
  2334
quick_and_dirty, instead of historical poking into mutable reference.
wenzelm@52059
  2335
wenzelm@52060

  2337
INCOMPATIBILITY.
wenzelm@52060
  2338
wenzelm@52430
  2339
* Proper diagnostic command 'print_state'.  Old 'pr' (with its
wenzelm@52430
  2340
implicit change of some global references) is retained for now as
wenzelm@52430
  2341
control command, e.g. for ProofGeneral 3.7.x.
wenzelm@52430
  2342
wenzelm@52549
  2343
* Discontinued 'print_drafts' command with its old-fashioned PS output
wenzelm@52549
  2344
and Unix command-line print spooling.  Minor INCOMPATIBILITY: use
wenzelm@52549
  2345
'display_drafts' instead and print via the regular document viewer.
wenzelm@52549
  2346
wenzelm@53971

*** Prover IDE -- Isabelle/Scala/jEdit ***
wenzelm@51533
  2352
wenzelm@53971
  2353
* New manual "jedit" for Isabelle/jEdit, see isabelle doc or
wenzelm@53852
  2354
Documentation panel.
wenzelm@53852
  2355
wenzelm@53971
  2356
* Dockable window "Documentation" provides access to Isabelle
wenzelm@53971
  2357
documentation.
wenzelm@52646
  2358
wenzelm@52949
  2359
* Dockable window "Find" provides query operations for formal entities
wenzelm@52949
  2360
(GUI front-end to 'find_theorems' command).
wenzelm@52949
  2361
wenzelm@53050
  2362
* Dockable window "Sledgehammer" manages asynchronous / parallel
wenzelm@53050
  2363
sledgehammer runs over existing document sources, independently of
wenzelm@53050
  2364
normal editing and checking process.
wenzelm@53050
  2365
wenzelm@51533
  2366
* Dockable window "Timing" provides an overview of relevant command
wenzelm@54332
  2367
timing information, depending on option jedit_timing_threshold.  The
wenzelm@54332
  2368
same timing information is shown in the extended tooltip of the
wenzelm@54332
  2369
command keyword, when hovering the mouse over it while the CONTROL or
wenzelm@54332
  2370
COMMAND modifier is pressed.
wenzelm@51533
  2371
wenzelm@53971
  2372
* Improved dockable window "Theories": Continuous checking of proof
wenzelm@53971
  2373
document (visible and required parts) may be controlled explicitly,
wenzelm@53971
  2374
using check box or shortcut "C+e ENTER".  Individual theory nodes may
wenzelm@53971
  2375
be marked explicitly as required and checked in full, using check box
wenzelm@53971
  2376
or shortcut "C+e SPACE".
wenzelm@53971
  2377
wenzelm@54305
  2378
* Improved completion mechanism, which is now managed by the
wenzelm@54305
  2379
Isabelle/jEdit plugin instead of SideKick.  Refined table of Isabelle
wenzelm@54305
  2380
symbol abbreviations (see $ISABELLE_HOME/etc/symbols).
wenzelm@54305
  2381
wenzelm@54319
  2382
* Standard jEdit keyboard shortcut C+b complete-word is remapped to
wenzelm@54319
  2383
isabelle.complete for explicit completion in Isabelle sources.
wenzelm@54319
  2384
INCOMPATIBILITY wrt. jEdit defaults, may have to invent new shortcuts
wenzelm@54319
  2385
to resolve conflict.
wenzelm@54319
  2386
wenzelm@54305
  2387
* Improved support of various "minor modes" for Isabelle NEWS,
wenzelm@54305
  2388
options, session ROOT etc., with completion and SideKick tree view.
wenzelm@54305
  2389
wenzelm@53971
  2390
* Strictly monotonic document update, without premature cancellation of
wenzelm@53971
  2391
running transactions that are still needed: avoid reset/restart of
wenzelm@53971
  2392
such command executions while editing.
wenzelm@53271
  2393
wenzelm@53971
  2394
* Support for asynchronous print functions, as overlay to existing
wenzelm@53971
  2395
document content.
wenzelm@53971
  2396
wenzelm@53971
  2397
* Support for automatic tools in HOL, which try to prove or disprove
wenzelm@53971
  2398
toplevel theorem statements.
wenzelm@53971
  2399
wenzelm@53971
  2400
* Action isabelle.reset-font-size resets main text area font size
wenzelm@54365
  2401
according to Isabelle/Scala plugin option "jedit_font_reset_size" (see
wenzelm@54365
  2402
also "Plugin Options / Isabelle / General").  It can be bound to some
wenzelm@54365
  2403
keyboard shortcut by the user (e.g. C+0 and/or C+NUMPAD0).
wenzelm@53971
  2404
wenzelm@53971
  2405
* File specifications in jEdit (e.g. file browser) may refer to
wenzelm@54351
  2406
$ISABELLE_HOME and $ISABELLE_HOME_USER on all platforms.  Discontinued
wenzelm@54351
  2407
obsolete $ISABELLE_HOME_WINDOWS variable.
wenzelm@53971
  2408
wenzelm@53971
  2409
* Improved support for Linux look-and-feel "GTK+", see also "Utilities
wenzelm@53971
  2410
/ Global Options / Appearance".
wenzelm@53971
  2411
wenzelm@53971
  2412
* Improved support of native Mac OS X functionality via "MacOSX"
wenzelm@53971
  2413
plugin, which is now enabled by default.

wenzelm@51313
  2417
ballarin@54049
  2418
* Commands 'interpretation' and 'sublocale' are now target-sensitive.
ballarin@54049
  2419
In particular, 'interpretation' allows for non-persistent
ballarin@54049
  2420
interpretation within "context ... begin ... end" blocks offering a
ballarin@54049
  2421
light-weight alternative to 'sublocale'.  See "isar-ref" manual for
ballarin@54049
  2422
details.
haftmann@51747
  2423
ballarin@51565
  2424
* Improved locales diagnostic command 'print_dependencies'.
ballarin@51565
  2425
wenzelm@51313
  2426
* Discontinued obsolete 'axioms' command, which has been marked as
wenzelm@51313
  2427
legacy since Isabelle2009-2.  INCOMPATIBILITY, use 'axiomatization'
wenzelm@51313
  2428
instead, while observing its uniform scope for polymorphism.
wenzelm@51313
  2429
wenzelm@51316
  2430
* Discontinued empty name bindings in 'axiomatization'.
wenzelm@51316
  2431
INCOMPATIBILITY.
wenzelm@51316
  2432
wenzelm@53971
  2433
* System option "proofs" has been discontinued.  Instead the global
wenzelm@53971
  2434
state of Proofterm.proofs is persistently compiled into logic images
wenzelm@53971
  2435
as required, notably HOL-Proofs.  Users no longer need to change
wenzelm@53971
  2436
Proofterm.proofs dynamically.  Minor INCOMPATIBILITY.
wenzelm@53971
  2437
wenzelm@53971
  2438
* Syntax translation functions (print_translation etc.) always depend
wenzelm@53971
  2439
on Proof.context.  Discontinued former "(advanced)" option -- this is
wenzelm@53971
  2440
now the default.  Minor INCOMPATIBILITY.
wenzelm@53971
  2441
wenzelm@53971
  2442
* Former global reference trace_unify_fail is now available as
wenzelm@53971
  2443
configuration option "unify_trace_failure" (global context only).
wenzelm@53971
  2444
wenzelm@52463
  2445
* SELECT_GOAL now retains the syntactic context of the overall goal
wenzelm@52463
  2446
state (schematic variables etc.).  Potential INCOMPATIBILITY in rare
wenzelm@52463
  2447
situations.

hoelzl@51002
  2450
*** HOL ***
hoelzl@51002
  2451
wenzelm@54032
  2452
* Stronger precedence of syntax for big intersection and union on
wenzelm@54032
  2453
sets, in accordance with corresponding lattice operations.
wenzelm@54032
  2454
INCOMPATIBILITY.
wenzelm@54032
  2455
wenzelm@54032
  2456
* Notation "{p:A. P}" now allows tuple patterns as well.
wenzelm@54032
  2457
wenzelm@54032
  2458
* Nested case expressions are now translated in a separate check phase
wenzelm@54032
  2459
rather than during parsing. The data for case combinators is separated
wenzelm@54032
  2460
from the datatype package. The declaration attribute
wenzelm@54032
  2461
"case_translation" can be used to register new case combinators:
wenzelm@54032
  2462
wenzelm@54032
  2463
  declare [[case_translation case_combinator constructor1 ... constructorN]]
haftmann@52637
  2464
haftmann@52435
  2465
* Code generator:
wenzelm@53160
  2466
  - 'code_printing' unifies 'code_const' / 'code_type' / 'code_class' /
wenzelm@53160
  2467
    'code_instance'.
wenzelm@53160
  2468
  - 'code_identifier' declares name hints for arbitrary identifiers in
wenzelm@53160
  2469
    generated code, subsuming 'code_modulename'.
wenzelm@53983
  2470
wenzelm@53983
  2471
See the isar-ref manual for syntax diagrams, and the HOL theories for
wenzelm@53983
  2472
examples.
haftmann@52435
  2473
wenzelm@54032
  2474
* Attibute 'code': 'code' now declares concrete and abstract code
wenzelm@54032
  2475
equations uniformly.  Use explicit 'code equation' and 'code abstract'
wenzelm@54032
  2476
to distinguish both when desired.
wenzelm@54032
  2477
wenzelm@54032
  2478
* Discontinued theories Code_Integer and Efficient_Nat by a more
wenzelm@54032
  2479
fine-grain stack of theories Code_Target_Int, Code_Binary_Nat,
wenzelm@54032
  2480
Code_Target_Nat and Code_Target_Numeral.  See the tutorial on code
wenzelm@54032
  2481
generation for details.  INCOMPATIBILITY.
wenzelm@54032
  2482
wenzelm@54032
  2483
* Numeric types are mapped by default to target language numerals:
wenzelm@54032
  2484
natural (replaces former code_numeral) and integer (replaces former
wenzelm@54032
  2485
code_int).  Conversions are available as integer_of_natural /
wenzelm@54032
  2486
natural_of_integer / integer_of_nat / nat_of_integer (in HOL) and
wenzelm@54032
  2487
Code_Numeral.integer_of_natural / Code_Numeral.natural_of_integer (in
wenzelm@54032
  2488
ML).  INCOMPATIBILITY.
wenzelm@54032
  2489
wenzelm@54032
  2490
* Function package: For mutually recursive functions f and g, separate
wenzelm@54032
  2491
cases rules f.cases and g.cases are generated instead of unusable
wenzelm@54032
  2492
f_g.cases which exposed internal sum types. Potential INCOMPATIBILITY,
wenzelm@54032
  2493
in the case that the unusable rule was used nevertheless.
wenzelm@54032
  2494
wenzelm@54032
  2495
* Function package: For each function f, new rules f.elims are
wenzelm@54032
  2496
generated, which eliminate equalities of the form "f x = t".
wenzelm@54032
  2497
wenzelm@54032
  2498
* New command 'fun_cases' derives ad-hoc elimination rules for
wenzelm@54032
  2499
function equations as simplified instances of f.elims, analogous to
wenzelm@54032
  2500
inductive_cases.  See ~~/src/HOL/ex/Fundefs.thy for some examples.
blanchet@53307
  2501
kuncar@54021
  2502
* Lifting:
kuncar@54021
  2503
  - parametrized correspondence relations are now supported:
wenzelm@54378
  2504
    + parametricity theorems for the raw term can be specified in
kuncar@54021
  2505
      the command lift_definition, which allow us to generate stronger
kuncar@54021
  2506
      transfer rules
kuncar@54021
  2507
    + setup_lifting generates stronger transfer rules if parametric
kuncar@54021
  2508
      correspondence relation can be generated
kuncar@54021
  2509
    + various new properties of the relator must be specified to support
kuncar@54021
  2510
      parametricity
kuncar@54021
  2511
    + parametricity theorem for the Quotient relation can be specified
kuncar@54021
  2512
  - setup_lifting generates domain rules for the Transfer package
kuncar@54021
  2513
  - stronger reflexivity prover of respectfulness theorems for type
kuncar@54021
  2514
    copies
kuncar@54021
  2515
  - ===> and --> are now local. The symbols can be introduced
kuncar@54021
  2516
    by interpreting the locale lifting_syntax (typically in an
kuncar@54021
  2517
    anonymous context)
wenzelm@54378
  2518
  - Lifting/Transfer relevant parts of Library/Quotient_* are now in
kuncar@54021
  2519
    Main. Potential INCOMPATIBILITY
kuncar@54021
  2520
  - new commands for restoring and deleting Lifting/Transfer context:
kuncar@54021
  2521
    lifting_forget, lifting_update
wenzelm@54378
  2522
  - the command print_quotmaps was renamed to print_quot_maps.
kuncar@54021
  2523
    INCOMPATIBILITY
kuncar@54021
  2524
kuncar@54021
  2525
* Transfer:
wenzelm@54378
  2526
  - better support for domains in Transfer: replace Domainp T
kuncar@54021
  2527
    by the actual invariant in a transferred goal
kuncar@54021
  2528
  - transfer rules can have as assumptions other transfer rules
kuncar@54021
  2529
  - Experimental support for transferring from the raw level to the
kuncar@54021
  2530
    abstract level: Transfer.transferred attribute
kuncar@54021
  2531
  - Attribute version of the transfer method: untransferred attribute
kuncar@54021
  2532
haftmann@52286
  2533
* Reification and reflection:
wenzelm@53160
  2534
  - Reification is now directly available in HOL-Main in structure
wenzelm@53160
  2535
    "Reification".
wenzelm@53160
  2536
  - Reflection now handles multiple lists with variables also.
wenzelm@53160
  2537
  - The whole reflection stack has been decomposed into conversions.
haftmann@52286
  2538
INCOMPATIBILITY.
haftmann@52286
  2539
haftmann@51489
  2540
* Revised devices for recursive definitions over finite sets:
haftmann@51489
  2541
  - Only one fundamental fold combinator on finite set remains:
haftmann@51489
  2542
    Finite_Set.fold :: ('a => 'b => 'b) => 'b => 'a set => 'b
haftmann@51489
  2543
    This is now identity on infinite sets.
wenzelm@52745
  2544
  - Locales ("mini packages") for fundamental definitions with
haftmann@51489
  2545
    Finite_Set.fold: folding, folding_idem.
haftmann@51489
  2546
  - Locales comm_monoid_set, semilattice_order_set and
haftmann@51489
  2547
    semilattice_neutr_order_set for big operators on sets.
haftmann@51489
  2548
    See theory Big_Operators for canonical examples.
haftmann@51489
  2549
    Note that foundational constants comm_monoid_set.F and
haftmann@51489
  2550
    semilattice_set.F correspond to former combinators fold_image
haftmann@51489
  2551
    and fold1 respectively.  These are now gone.  You may use
haftmann@51490
  2552
    those foundational constants as substitutes, but it is
wenzelm@53983
  2553
    preferable to interpret the above locales accordingly.
haftmann@51489
  2554
  - Dropped class ab_semigroup_idem_mult (special case of lattice,
haftmann@51489
  2555
    no longer needed in connection with Finite_Set.fold etc.)
haftmann@51489
  2556
  - Fact renames:
haftmann@51489
  2557
      card.union_inter ~> card_Un_Int [symmetric]
haftmann@51489
  2558
      card.union_disjoint ~> card_Un_disjoint
haftmann@51489
  2559
INCOMPATIBILITY.
haftmann@51489
  2560
haftmann@51487
  2561
* Locale hierarchy for abstract orderings and (semi)lattices.
haftmann@51487
  2562
wenzelm@53526
  2563
* Complete_Partial_Order.admissible is defined outside the type class
wenzelm@53526
  2564
ccpo, but with mandatory prefix ccpo. Admissibility theorems lose the
wenzelm@53526
  2565
class predicate assumption or sort constraint when possible.
Andreas@53362
  2566
INCOMPATIBILITY.
Andreas@53362
  2567
wenzelm@53160
  2568
* Introduce type class "conditionally_complete_lattice": Like a
wenzelm@53160
  2569
complete lattice but does not assume the existence of the top and
wenzelm@53160
  2570
bottom elements.  Allows to generalize some lemmas about reals and
wenzelm@53160
  2571
extended reals.  Removed SupInf and replaced it by the instantiation
wenzelm@53160
  2572
of conditionally_complete_lattice for real. Renamed lemmas about
wenzelm@53160
  2573
conditionally-complete lattice from Sup_... to cSup_... and from
wenzelm@53160
  2574
Inf_...  to cInf_... to avoid hidding of similar complete lattice
wenzelm@53160
  2575
lemmas.
wenzelm@53160
  2576
wenzelm@53160
  2577
* Introduce type class linear_continuum as combination of
wenzelm@53160
  2578
conditionally-complete lattices and inner dense linorders which have
wenzelm@53160
  2579
more than one element.  INCOMPATIBILITY.
wenzelm@53160
  2580
wenzelm@53983
  2581
* Introduced type classes order_top and order_bot. The old classes top
wenzelm@53983
  2582
and bot only contain the syntax without assumptions.  INCOMPATIBILITY:
wenzelm@53983
  2583
Rename bot -> order_bot, top -> order_top
lammich@53683
  2584
wenzelm@53160
  2585
* Introduce type classes "no_top" and "no_bot" for orderings without
wenzelm@53160
  2586
top and bottom elements.
hoelzl@51732
  2587
hoelzl@51732
  2588
* Split dense_linorder into inner_dense_order and no_top, no_bot.
hoelzl@51732
  2589
hoelzl@51732
  2590
* Complex_Main: Unify and move various concepts from
wenzelm@53160
  2591
HOL-Multivariate_Analysis to HOL-Complex_Main.
hoelzl@51732
  2592
wenzelm@53983
  2593
 - Introduce type class (lin)order_topology and
wenzelm@53983
  2594
   linear_continuum_topology.  Allows to generalize theorems about
wenzelm@53983
  2595
   limits and order.  Instances are reals and extended reals.
hoelzl@51732
  2596
hoelzl@51732
  2597
 - continuous and continuos_on from Multivariate_Analysis:
wenzelm@53983
  2598
   "continuous" is the continuity of a function at a filter.  "isCont"
wenzelm@53983
  2599
   is now an abbrevitation: "isCont x f == continuous (at _) f".
wenzelm@53983
  2600
wenzelm@53983
  2601
   Generalized continuity lemmas from isCont to continuous on an
wenzelm@53983
  2602
   arbitrary filter.
wenzelm@53983
  2603
wenzelm@53983
  2604
 - compact from Multivariate_Analysis. Use Bolzano's lemma to prove
wenzelm@53983
  2605
   compactness of closed intervals on reals. Continuous functions
wenzelm@53983
  2606
   attain infimum and supremum on compact sets. The inverse of a
wenzelm@53983
  2607
   continuous function is continuous, when the function is continuous
wenzelm@53983
  2608
   on a compact set.
hoelzl@51732
  2609
hoelzl@51732
  2610
 - connected from Multivariate_Analysis. Use it to prove the
hoelzl@51775
  2611
   intermediate value theorem. Show connectedness of intervals on
hoelzl@51775
  2612
   linear_continuum_topology).
hoelzl@51732
  2613
hoelzl@51732
  2614
 - first_countable_topology from Multivariate_Analysis. Is used to
wenzelm@53983
  2615
   show equivalence of properties on the neighbourhood filter of x and
wenzelm@53983
  2616
   on all sequences converging to x.
wenzelm@53983
  2617
wenzelm@53983
  2618
 - FDERIV: Definition of has_derivative moved to Deriv.thy. Moved
wenzelm@53983
  2619
   theorems from Library/FDERIV.thy to Deriv.thy and base the
wenzelm@53983
  2620
   definition of DERIV on FDERIV. Add variants of DERIV and FDERIV
wenzelm@53983

 - Removed the within-filter. It is replaced by the principal filter:
hoelzl@51732
  2625
hoelzl@51732
  2626
     F within X = inf F (principal X)
hoelzl@51732
  2627
hoelzl@51732
  2628
 - Introduce "at x within U" as a single constant, "at x" is now an
hoelzl@51732
  2629
   abbreviation for "at x within UNIV"
hoelzl@51732
  2630
wenzelm@53983
  2631
 - Introduce named theorem collections tendsto_intros,
wenzelm@53983
  2632
   continuous_intros, continuous_on_intros and FDERIV_intros. Theorems
wenzelm@53983
  2633
   in tendsto_intros (or FDERIV_intros) are also available as
wenzelm@53983
  2634
   tendsto_eq_intros (or FDERIV_eq_intros) where the right-hand side
wenzelm@53983
  2635
   is replaced by a congruence rule. This allows to apply them as
wenzelm@53983
  2636
   intro rules and then proving equivalence by the simplifier.

isar-ref manual and ~~/src/HOL/ex/Adhoc_Overloading_Examples.thy).
wenzelm@54032
  2672
wenzelm@54032
  2673
* Library/Polynomial.thy:
wenzelm@54032
  2674
  - Use lifting for primitive definitions.
wenzelm@54032
  2675
  - Explicit conversions from and to lists of coefficients, used for
wenzelm@54032
  2676
    generated code.
wenzelm@54032
  2677
  - Replaced recursion operator poly_rec by fold_coeffs.
wenzelm@54032
  2678
  - Prefer pre-existing gcd operation for gcd.

* New Library/Simps_Case_Conv.thy: Provides commands simps_of_case and
wenzelm@54032
  2686
case_of_simps to convert function definitions between a list of
wenzelm@54032
  2687
equations with patterns on the lhs and a single equation with case

* Imperative-HOL: The MREC combinator is considered legacy and no
wenzelm@53160
  2703
longer included by default. INCOMPATIBILITY, use partial_function
wenzelm@53160
  2704
instead, or import theory Legacy_Mrec as a fallback.
wenzelm@53160
  2705
wenzelm@53983
  2706
* HOL-Algebra: Discontinued theories ~~/src/HOL/Algebra/abstract and
wenzelm@53983
  2707
~~/src/HOL/Algebra/poly.  Existing theories should be based on
wenzelm@53983
  2708
~~/src/HOL/Library/Polynomial instead.  The latter provides
wenzelm@53983
  2709
integration with HOL's type classes for rings.  INCOMPATIBILITY.
