*** General ***
wenzelm@54702
     8
wenzelm@54702
     9
* Document antiquotation @{url} produces markup for the given URL,
wenzelm@54702
    10
which results in an active hyperlink within the text.
wenzelm@54702
    11
wenzelm@54705
    12
* Document antiquotation @{file_unchecked} is like @{file}, but does
wenzelm@54705
    13
not check existence within the file-system.
wenzelm@54705
    14
wenzelm@54732
    15
* Discontinued legacy_isub_isup, which was a temporary Isabelle/ML
wenzelm@54732
    16
workaround in Isabelle2013-1.  The prover process no longer accepts
wenzelm@54732
    17
old identifier syntax with \<^isub> or \<^isup>.
wenzelm@54732
    18
wenzelm@55029
    19
* Syntax of document antiquotation @{rail} now uses \<newline> instead
wenzelm@55029
    20
of "\\", to avoid the optical illusion of escaped backslash within
wenzelm@55029
    21
string token.  Minor INCOMPATIBILITY.
wenzelm@55029
    22
wenzelm@55122
    23
* Lexical syntax (inner and outer) supports text cartouches with
wenzelm@55668
    24
arbitrary nesting, and without escapes of quotes etc.  The Prover IDE
wenzelm@55668
    25
supports input methods via ` (backquote), or << and >> (double angle
wenzelm@55668
    26
brackets).
wenzelm@55122
    27
wenzelm@54702

    29
*** Prover IDE -- Isabelle/Scala/jEdit ***
wenzelm@54533
    30
wenzelm@54533
    31
* Auxiliary files ('ML_file' etc.) are managed by the Prover IDE.
wenzelm@54533
    32
Open text buffers take precedence over copies within the file-system.
wenzelm@54533
    33
wenzelm@55536
    34
* Improved support for Isabelle/ML, with jEdit mode "isabelle-ml" for
wenzelm@55536
    35
auxiliary ML files.
wenzelm@55536
    36
wenzelm@55654
    37
* Improved completion based on context information about embedded
wenzelm@55716
    38
languages: keywords are only completed for outer syntax, symbols or
wenzelm@55716
    39
antiquotations for languages that support them.  E.g. no symbol
wenzelm@55716
    40
completion for ML source, but within ML strings, comments,
wenzelm@55716
    41
antiquotations.
wenzelm@55654
    42
wenzelm@54688
    43
* Document panel: simplied interaction where every single mouse click
wenzelm@54688
    44
(re)opens document via desktop environment or as jEdit buffer.
wenzelm@54688
    45
wenzelm@54881
    46
* Option "jedit_print_mode" (see also "Plugin Options / Isabelle /
wenzelm@54881
    47
General") allows to specify additional print modes for the prover
wenzelm@54881
    48
process, without requiring old-fashioned command-line invocation of
wenzelm@54881
    49
"isabelle jedit -m MODE".
wenzelm@54881
    50
lars@55316
    51
* New panel: Simplifier trace.  Provides an interactive view of the
lars@55316
    52
simplification process, enabled by the newly-introduced
lars@55316
    53
"simplifier_trace" declaration.
lars@55316

wenzelm@55001
    56
*** Pure ***
wenzelm@55001
    57
wenzelm@55385
    58
* Low-level type-class commands 'classes', 'classrel', 'arities' have
wenzelm@55385
    59
been discontinued to avoid the danger of non-trivial axiomatization
wenzelm@55385
    60
that is not immediately visible.  INCOMPATIBILITY, use regular
wenzelm@55385
    61
'instance' with proof.  The required OFCLASS(...) theorem might be
wenzelm@55385
    62
postulated via 'axiomatization' beforehand, or the proof finished
wenzelm@55385
    63
trivially if the underlying class definition is made vacuous (without
wenzelm@55385
    64
any assumptions).  See also Isabelle/ML operations
wenzelm@55385
    65
Axclass.axiomatize_class, Axclass.axiomatize_classrel,
wenzelm@55385
    66
Axclass.axiomatize_arity.
wenzelm@55385
    67
wenzelm@55143
    68
* Attributes "where" and "of" allow an optional context of local
wenzelm@55143
    69
variables ('for' declaration): these variables become schematic in the
wenzelm@55143
    70
instantiated theorem.
wenzelm@55143
    71
wenzelm@55152
    72
* Obsolete attribute "standard" has been discontinued (legacy since
wenzelm@55152
    73
Isabelle2012).  Potential INCOMPATIBILITY, use explicit 'for' context
wenzelm@55152
    74
where instantiations with schematic variables are intended (for
wenzelm@55152
    75
declaration commands like 'lemmas' or attributes like "of").  The
wenzelm@55152
    76
following temporary definition may help to port old applications:
wenzelm@55152
    77
wenzelm@55152
    78
  attribute_setup standard =
wenzelm@55152
    79
    "Scan.succeed (Thm.rule_attribute (K Drule.export_without_context))"
wenzelm@55152
    80
wenzelm@55001
    81
* More thorough check of proof context for goal statements and
wenzelm@55006
    82
attributed fact expressions (concerning background theory, declared
wenzelm@55006
    83
hyps).  Potential INCOMPATIBILITY, tools need to observe standard
wenzelm@55006
    84
context discipline.  See also Assumption.add_assumes and the more
wenzelm@55006
    85
primitive Thm.assume_hyps.
wenzelm@55001
    86
wenzelm@55108
    87
* Inner syntax token language allows regular quoted strings "..."
wenzelm@55108
    88
(only makes sense in practice, if outer syntax is delimited
wenzelm@55108
    89
differently).
wenzelm@55108

haftmann@54227
    92
*** HOL ***
haftmann@54227
    93
haftmann@55818
    94
* HOL-Word:
haftmann@55818
    95
  * Abandoned fact collection "word_arith_alts", which is a
haftmann@55818
    96
  duplicate of "word_arith_wis".
haftmann@55818
    97
  * Dropped first (duplicated) element in fact collections
haftmann@55818
    98
  "sint_word_ariths", "word_arith_alts", "uint_word_ariths",
haftmann@55818
    99
  "uint_word_arith_bintrs".
haftmann@55818
   100
haftmann@55757
   101
* Code generator: explicit proof contexts in many ML interfaces.
haftmann@55757
   102
INCOMPATIBILITY.
haftmann@55757
   103
haftmann@55686
   104
* Code generator: minimize exported identifiers by default.
haftmann@55757
   105
Minor INCOMPATIBILITY.
haftmann@55686
   106
haftmann@55677
   107
* Code generation for SML and OCaml: dropped arcane "no_signatures" option.
haftmann@55757
   108
Minor INCOMPATIBILITY.
haftmann@55677
   109
wenzelm@55139
   110
* Simproc "finite_Collect" is no longer enabled by default, due to
wenzelm@55139
   111
spurious crashes and other surprises.  Potential INCOMPATIBILITY.
wenzelm@55139
   112
blanchet@55098
   113
* Moved new (co)datatype package and its dependencies from "HOL-BNF" to "HOL".
blanchet@55098
   114
  The "bnf", "wrap_free_constructors", "datatype_new", "codatatype",
blanchet@55875
   115
  "primcorec", and "primcorecursive" commands are now part of "Main".

blanchet@55875
   162
    INCOMPATIBILITY.
blanchet@55875
   163
blanchet@55643
   164

  relators, and their selectors are now produced using the new BNF-based
blanchet@55585
   174
  datatype package.
blanchet@55519
   175
  Renamed constants:

      smt_proofs
blanchet@55183

      isar_try0 ~> try0_isar
blanchet@55183
   210
    INCOMPATIBILITY.
blanchet@55183
   211
blanchet@55315
   212
* Metis:
blanchet@55315
   213
  - Removed legacy proof method 'metisFT'. Use 'metis (full_types)' instead.
blanchet@55315
   214
    INCOMPATIBILITY.
blanchet@55315
   215
blanchet@55183
   216
* Try0: Added 'algebra' and 'meson' to the set of proof methods.
blanchet@55183
   217
blanchet@55519
   218
* Command renaming: enriched_type ~> functor. INCOMPATIBILITY.
blanchet@55519
   219
wenzelm@55015
   220
* The symbol "\<newline>" may be used within char or string literals
wenzelm@55015
   221
to represent (Char Nibble0 NibbleA), i.e. ASCII newline.
wenzelm@55015
   222
wenzelm@55007
   223
* Activation of Z3 now works via "z3_non_commercial" system option
wenzelm@55007
   224
(without requiring restart), instead of former settings variable
wenzelm@55007
   225
"Z3_NON_COMMERCIAL".  The option can be edited in Isabelle/jEdit menu

   230
wenzelm@54893
   231

haftmann@54890
   232
with the given constants.
haftmann@54890
   233
haftmann@54864
   234
* Abolished slightly odd global lattice interpretation for min/max.

   348
haftmann@54230
   349

Try with "using <rule for addition> of [... "- _" ...]" by simp".
haftmann@54230
   351
haftmann@54230
   352
c) Simplification with "diff_def": just drop "diff_def".

   402
* Proper context discipline for read_instantiate and instantiate_tac:
wenzelm@55143
   403
variables that are meant to become schematic need to be given as
wenzelm@55143
   404
fixed, and are generalized by the explicit context of local variables.
wenzelm@55143
   405
This corresponds to Isar attributes "where" and "of" with 'for'
wenzelm@55143
   406
declaration.  INCOMPATIBILITY, also due to potential change of indices
wenzelm@55143
   407
of schematic variables.
wenzelm@55143
   408
wenzelm@54449

rewrite_goals_rule, rewrite_goals_tac etc. INCOMPATIBILITY, need to
wenzelm@54742

actually belongs to it).
wenzelm@54742
   418
wenzelm@55547

* Subtle change of semantics of Thm.eq_thm: theory stamps are not
wenzelm@55547
   420
compared (according to Thm.thm_ord), but assumed to be covered by the
wenzelm@55547
   421
current background theory.  Thus equivalent data produced in different
wenzelm@55547
   422
branches of the theory graph usually coincides (e.g. relevant for
wenzelm@55547
   423
theory merge).  Note that the softer Thm.eq_thm_prop is often more
wenzelm@55547
   424
appropriate than Thm.eq_thm.

   526
(GUI front-end to 'find_theorems' command).
wenzelm@52949
   527
wenzelm@53050
   528
* Dockable window "Sledgehammer" manages asynchronous / parallel
wenzelm@53050
   529
sledgehammer runs over existing document sources, independently of
wenzelm@53050
   530
normal editing and checking process.
wenzelm@53050
   531
wenzelm@51533
   532
* Dockable window "Timing" provides an overview of relevant command
wenzelm@54332
   533
timing information, depending on option jedit_timing_threshold.  The
wenzelm@54332
   534
same timing information is shown in the extended tooltip of the
wenzelm@54332
   535
command keyword, when hovering the mouse over it while the CONTROL or
wenzelm@54332
   536
COMMAND modifier is pressed.
wenzelm@51533
   537
wenzelm@53971
   538
* Improved dockable window "Theories": Continuous checking of proof
wenzelm@53971
   539
document (visible and required parts) may be controlled explicitly,
wenzelm@53971
   540
using check box or shortcut "C+e ENTER".  Individual theory nodes may
wenzelm@53971
   541
be marked explicitly as required and checked in full, using check box
wenzelm@53971
   542
or shortcut "C+e SPACE".
wenzelm@53971
   543
wenzelm@54305
   544
* Improved completion mechanism, which is now managed by the
wenzelm@54305
   545
Isabelle/jEdit plugin instead of SideKick.  Refined table of Isabelle
wenzelm@54305
   546
symbol abbreviations (see $ISABELLE_HOME/etc/symbols).
wenzelm@54305
   547
wenzelm@54319
   548
* Standard jEdit keyboard shortcut C+b complete-word is remapped to
wenzelm@54319
   549
isabelle.complete for explicit completion in Isabelle sources.
wenzelm@54319
   550
INCOMPATIBILITY wrt. jEdit defaults, may have to invent new shortcuts
wenzelm@54319
   551
to resolve conflict.
wenzelm@54319
   552
wenzelm@54305
   553
* Improved support of various "minor modes" for Isabelle NEWS,
wenzelm@54305
   554
options, session ROOT etc., with completion and SideKick tree view.
wenzelm@54305
   555
wenzelm@53971
   556
* Strictly monotonic document update, without premature cancellation of
wenzelm@53971
   557
running transactions that are still needed: avoid reset/restart of
wenzelm@53971
   558
such command executions while editing.
wenzelm@53271
   559
wenzelm@53971
   560
* Support for asynchronous print functions, as overlay to existing
wenzelm@53971
   561
document content.
wenzelm@53971
   562
wenzelm@53971
   563
* Support for automatic tools in HOL, which try to prove or disprove
wenzelm@53971
   564
toplevel theorem statements.
wenzelm@53971
   565
wenzelm@53971
   566
* Action isabelle.reset-font-size resets main text area font size
wenzelm@54365
   567
according to Isabelle/Scala plugin option "jedit_font_reset_size" (see
wenzelm@54365
   568
also "Plugin Options / Isabelle / General").  It can be bound to some
wenzelm@54365
   569
keyboard shortcut by the user (e.g. C+0 and/or C+NUMPAD0).
wenzelm@53971
   570
wenzelm@53971
   571
* File specifications in jEdit (e.g. file browser) may refer to
wenzelm@54351
   572
$ISABELLE_HOME and $ISABELLE_HOME_USER on all platforms.  Discontinued
wenzelm@54351
   573
obsolete $ISABELLE_HOME_WINDOWS variable.
wenzelm@53971
   574
wenzelm@53971
   575
* Improved support for Linux look-and-feel "GTK+", see also "Utilities
wenzelm@53971
   576
/ Global Options / Appearance".
wenzelm@53971
   577
wenzelm@53971
   578
* Improved support of native Mac OS X functionality via "MacOSX"
wenzelm@53971
   579
plugin, which is now enabled by default.

wenzelm@51313
   583
ballarin@54049
   584
* Commands 'interpretation' and 'sublocale' are now target-sensitive.
ballarin@54049
   585
In particular, 'interpretation' allows for non-persistent
ballarin@54049
   586
interpretation within "context ... begin ... end" blocks offering a
ballarin@54049
   587
light-weight alternative to 'sublocale'.  See "isar-ref" manual for
ballarin@54049
   588
details.
haftmann@51747
   589
ballarin@51565
   590
* Improved locales diagnostic command 'print_dependencies'.
ballarin@51565
   591
wenzelm@51313
   592
* Discontinued obsolete 'axioms' command, which has been marked as
wenzelm@51313
   593
legacy since Isabelle2009-2.  INCOMPATIBILITY, use 'axiomatization'
wenzelm@51313
   594
instead, while observing its uniform scope for polymorphism.
wenzelm@51313
   595
wenzelm@51316
   596
* Discontinued empty name bindings in 'axiomatization'.
wenzelm@51316
   597
INCOMPATIBILITY.
wenzelm@51316
   598
wenzelm@53971
   599
* System option "proofs" has been discontinued.  Instead the global
wenzelm@53971
   600
state of Proofterm.proofs is persistently compiled into logic images
wenzelm@53971
   601
as required, notably HOL-Proofs.  Users no longer need to change
wenzelm@53971
   602
Proofterm.proofs dynamically.  Minor INCOMPATIBILITY.
wenzelm@53971
   603
wenzelm@53971
   604
* Syntax translation functions (print_translation etc.) always depend
wenzelm@53971
   605
on Proof.context.  Discontinued former "(advanced)" option -- this is
wenzelm@53971
   606
now the default.  Minor INCOMPATIBILITY.
wenzelm@53971
   607
wenzelm@53971
   608
* Former global reference trace_unify_fail is now available as
wenzelm@53971
   609
configuration option "unify_trace_failure" (global context only).
wenzelm@53971
   610
wenzelm@52463
   611
* SELECT_GOAL now retains the syntactic context of the overall goal
wenzelm@52463
   612
state (schematic variables etc.).  Potential INCOMPATIBILITY in rare
wenzelm@52463
   613
situations.

hoelzl@51002
   617
wenzelm@54032
   618
* Stronger precedence of syntax for big intersection and union on
wenzelm@54032
   619
sets, in accordance with corresponding lattice operations.
wenzelm@54032
   620
INCOMPATIBILITY.
wenzelm@54032
   621
wenzelm@54032
   622
* Notation "{p:A. P}" now allows tuple patterns as well.
wenzelm@54032
   623
wenzelm@54032
   624
* Nested case expressions are now translated in a separate check phase
wenzelm@54032
   625
rather than during parsing. The data for case combinators is separated
wenzelm@54032
   626
from the datatype package. The declaration attribute
wenzelm@54032
   627
"case_translation" can be used to register new case combinators:
wenzelm@54032
   628
wenzelm@54032
   629
  declare [[case_translation case_combinator constructor1 ... constructorN]]
haftmann@52637
   630
haftmann@52435
   631
* Code generator:
wenzelm@53160
   632
  - 'code_printing' unifies 'code_const' / 'code_type' / 'code_class' /
wenzelm@53160
   633
    'code_instance'.
wenzelm@53160
   634
  - 'code_identifier' declares name hints for arbitrary identifiers in
wenzelm@53160
   635
    generated code, subsuming 'code_modulename'.
wenzelm@53983
   636
wenzelm@53983
   637
See the isar-ref manual for syntax diagrams, and the HOL theories for
wenzelm@53983
   638
examples.
haftmann@52435
   639
wenzelm@54032
   640
* Attibute 'code': 'code' now declares concrete and abstract code
wenzelm@54032
   641
equations uniformly.  Use explicit 'code equation' and 'code abstract'
wenzelm@54032
   642
to distinguish both when desired.
wenzelm@54032
   643
wenzelm@54032
   644
* Discontinued theories Code_Integer and Efficient_Nat by a more
wenzelm@54032
   645
fine-grain stack of theories Code_Target_Int, Code_Binary_Nat,
wenzelm@54032
   646
Code_Target_Nat and Code_Target_Numeral.  See the tutorial on code
wenzelm@54032
   647
generation for details.  INCOMPATIBILITY.
wenzelm@54032
   648
wenzelm@54032
   649
* Numeric types are mapped by default to target language numerals:
wenzelm@54032
   650
natural (replaces former code_numeral) and integer (replaces former
wenzelm@54032
   651
code_int).  Conversions are available as integer_of_natural /
wenzelm@54032
   652
natural_of_integer / integer_of_nat / nat_of_integer (in HOL) and
wenzelm@54032
   653
Code_Numeral.integer_of_natural / Code_Numeral.natural_of_integer (in
wenzelm@54032
   654
ML).  INCOMPATIBILITY.
wenzelm@54032
   655
wenzelm@54032
   656
* Function package: For mutually recursive functions f and g, separate
wenzelm@54032
   657
cases rules f.cases and g.cases are generated instead of unusable
wenzelm@54032
   658
f_g.cases which exposed internal sum types. Potential INCOMPATIBILITY,
wenzelm@54032
   659
in the case that the unusable rule was used nevertheless.
wenzelm@54032
   660
wenzelm@54032
   661
* Function package: For each function f, new rules f.elims are
wenzelm@54032
   662
generated, which eliminate equalities of the form "f x = t".
wenzelm@54032
   663
wenzelm@54032
   664
* New command 'fun_cases' derives ad-hoc elimination rules for
wenzelm@54032
   665
function equations as simplified instances of f.elims, analogous to
wenzelm@54032
   666
inductive_cases.  See ~~/src/HOL/ex/Fundefs.thy for some examples.
blanchet@53307
   667
kuncar@54021
   668
* Lifting:
kuncar@54021
   669
  - parametrized correspondence relations are now supported:
wenzelm@54378
   670
    + parametricity theorems for the raw term can be specified in
kuncar@54021
   671
      the command lift_definition, which allow us to generate stronger
kuncar@54021
   672
      transfer rules
kuncar@54021
   673
    + setup_lifting generates stronger transfer rules if parametric
kuncar@54021
   674
      correspondence relation can be generated
kuncar@54021
   675
    + various new properties of the relator must be specified to support
kuncar@54021
   676
      parametricity
kuncar@54021
   677
    + parametricity theorem for the Quotient relation can be specified
kuncar@54021
   678
  - setup_lifting generates domain rules for the Transfer package
kuncar@54021
   679
  - stronger reflexivity prover of respectfulness theorems for type
kuncar@54021
   680
    copies
kuncar@54021
   681
  - ===> and --> are now local. The symbols can be introduced
kuncar@54021
   682
    by interpreting the locale lifting_syntax (typically in an
kuncar@54021
   683
    anonymous context)
wenzelm@54378
   684
  - Lifting/Transfer relevant parts of Library/Quotient_* are now in
kuncar@54021
   685
    Main. Potential INCOMPATIBILITY
kuncar@54021
   686
  - new commands for restoring and deleting Lifting/Transfer context:
kuncar@54021
   687
    lifting_forget, lifting_update
wenzelm@54378
   688
  - the command print_quotmaps was renamed to print_quot_maps.
kuncar@54021
   689
    INCOMPATIBILITY
kuncar@54021
   690
kuncar@54021
   691
* Transfer:
wenzelm@54378
   692
  - better support for domains in Transfer: replace Domainp T
kuncar@54021
   693
    by the actual invariant in a transferred goal
kuncar@54021
   694
  - transfer rules can have as assumptions other transfer rules
kuncar@54021
   695
  - Experimental support for transferring from the raw level to the
kuncar@54021
   696
    abstract level: Transfer.transferred attribute
kuncar@54021
   697
  - Attribute version of the transfer method: untransferred attribute
kuncar@54021
   698
haftmann@52286
   699
* Reification and reflection:
wenzelm@53160
   700
  - Reification is now directly available in HOL-Main in structure
wenzelm@53160
   701
    "Reification".
wenzelm@53160
   702
  - Reflection now handles multiple lists with variables also.
wenzelm@53160
   703
  - The whole reflection stack has been decomposed into conversions.
haftmann@52286
   704
INCOMPATIBILITY.
haftmann@52286
   705
haftmann@51489
   706
* Revised devices for recursive definitions over finite sets:
haftmann@51489
   707
  - Only one fundamental fold combinator on finite set remains:
haftmann@51489
   708
    Finite_Set.fold :: ('a => 'b => 'b) => 'b => 'a set => 'b
haftmann@51489
   709
    This is now identity on infinite sets.
wenzelm@52745
   710
  - Locales ("mini packages") for fundamental definitions with
haftmann@51489
   711
    Finite_Set.fold: folding, folding_idem.
haftmann@51489
   712
  - Locales comm_monoid_set, semilattice_order_set and
haftmann@51489
   713
    semilattice_neutr_order_set for big operators on sets.
haftmann@51489
   714
    See theory Big_Operators for canonical examples.
haftmann@51489
   715
    Note that foundational constants comm_monoid_set.F and
haftmann@51489
   716
    semilattice_set.F correspond to former combinators fold_image
haftmann@51489
   717
    and fold1 respectively.  These are now gone.  You may use
haftmann@51490
   718
    those foundational constants as substitutes, but it is
wenzelm@53983
   719
    preferable to interpret the above locales accordingly.
haftmann@51489
   720
  - Dropped class ab_semigroup_idem_mult (special case of lattice,
haftmann@51489
   721
    no longer needed in connection with Finite_Set.fold etc.)
haftmann@51489
   722
  - Fact renames:
haftmann@51489
   723
      card.union_inter ~> card_Un_Int [symmetric]
haftmann@51489
   724
      card.union_disjoint ~> card_Un_disjoint
haftmann@51489
   725
INCOMPATIBILITY.
haftmann@51489
   726
haftmann@51487
   727
* Locale hierarchy for abstract orderings and (semi)lattices.
haftmann@51487
   728
wenzelm@53526
   729
* Complete_Partial_Order.admissible is defined outside the type class
wenzelm@53526
   730
ccpo, but with mandatory prefix ccpo. Admissibility theorems lose the
wenzelm@53526
   731
class predicate assumption or sort constraint when possible.
Andreas@53362
   732
INCOMPATIBILITY.
Andreas@53362
   733
wenzelm@53160
   734
* Introduce type class "conditionally_complete_lattice": Like a
wenzelm@53160
   735
complete lattice but does not assume the existence of the top and
wenzelm@53160
   736
bottom elements.  Allows to generalize some lemmas about reals and
wenzelm@53160
   737
extended reals.  Removed SupInf and replaced it by the instantiation
wenzelm@53160
   738
of conditionally_complete_lattice for real. Renamed lemmas about
wenzelm@53160
   739
conditionally-complete lattice from Sup_... to cSup_... and from
wenzelm@53160
   740
Inf_...  to cInf_... to avoid hidding of similar complete lattice
wenzelm@53160
   741
lemmas.
wenzelm@53160
   742
wenzelm@53160
   743
* Introduce type class linear_continuum as combination of
wenzelm@53160
   744
conditionally-complete lattices and inner dense linorders which have
wenzelm@53160
   745
more than one element.  INCOMPATIBILITY.
wenzelm@53160
   746
wenzelm@53983
   747
* Introduced type classes order_top and order_bot. The old classes top
wenzelm@53983
   748
and bot only contain the syntax without assumptions.  INCOMPATIBILITY:
wenzelm@53983
   749
Rename bot -> order_bot, top -> order_top
lammich@53683
   750
wenzelm@53160
   751
* Introduce type classes "no_top" and "no_bot" for orderings without
wenzelm@53160
   752
top and bottom elements.
hoelzl@51732
   753
hoelzl@51732
   754
* Split dense_linorder into inner_dense_order and no_top, no_bot.
hoelzl@51732
   755
hoelzl@51732
   756
* Complex_Main: Unify and move various concepts from
wenzelm@53160
   757
HOL-Multivariate_Analysis to HOL-Complex_Main.
hoelzl@51732
   758
wenzelm@53983
   759
 - Introduce type class (lin)order_topology and
wenzelm@53983
   760
   linear_continuum_topology.  Allows to generalize theorems about
wenzelm@53983
   761
   limits and order.  Instances are reals and extended reals.
hoelzl@51732
   762
hoelzl@51732
   763
 - continuous and continuos_on from Multivariate_Analysis:
wenzelm@53983
   764
   "continuous" is the continuity of a function at a filter.  "isCont"
wenzelm@53983
   765
   is now an abbrevitation: "isCont x f == continuous (at _) f".
wenzelm@53983
   766
wenzelm@53983
   767
   Generalized continuity lemmas from isCont to continuous on an
wenzelm@53983
   768
   arbitrary filter.
wenzelm@53983
   769
wenzelm@53983
   770
 - compact from Multivariate_Analysis. Use Bolzano's lemma to prove
wenzelm@53983
   771
   compactness of closed intervals on reals. Continuous functions
wenzelm@53983
   772
   attain infimum and supremum on compact sets. The inverse of a
wenzelm@53983
   773
   continuous function is continuous, when the function is continuous
wenzelm@53983
   774
   on a compact set.
hoelzl@51732
   775
hoelzl@51732
   776
 - connected from Multivariate_Analysis. Use it to prove the
hoelzl@51775
   777
   intermediate value theorem. Show connectedness of intervals on
hoelzl@51775
   778
   linear_continuum_topology).
hoelzl@51732
   779
hoelzl@51732
   780
 - first_countable_topology from Multivariate_Analysis. Is used to
wenzelm@53983
   781
   show equivalence of properties on the neighbourhood filter of x and
wenzelm@53983
   782
   on all sequences converging to x.
wenzelm@53983
   783
wenzelm@53983
   784
 - FDERIV: Definition of has_derivative moved to Deriv.thy. Moved
wenzelm@53983
   785
   theorems from Library/FDERIV.thy to Deriv.thy and base the
wenzelm@53983
   786
   definition of DERIV on FDERIV. Add variants of DERIV and FDERIV
wenzelm@53983
   787
   which are restricted to sets, i.e. to represent derivatives from
wenzelm@53983
   788
   left or right.
hoelzl@51732
   789
hoelzl@51732
   790
 - Removed the within-filter. It is replaced by the principal filter:
hoelzl@51732
   791
hoelzl@51732
   792
     F within X = inf F (principal X)
hoelzl@51732
   793
hoelzl@51732
   794
 - Introduce "at x within U" as a single constant, "at x" is now an
hoelzl@51732
   795
   abbreviation for "at x within UNIV"

 - Introduce named theorem collections tendsto_intros,
wenzelm@53983
   798
   continuous_intros, continuous_on_intros and FDERIV_intros. Theorems
wenzelm@53983
   799
   in tendsto_intros (or FDERIV_intros) are also available as
wenzelm@53983
   800
   tendsto_eq_intros (or FDERIV_eq_intros) where the right-hand side
wenzelm@53983
   801
   is replaced by a congruence rule. This allows to apply them as
wenzelm@53983
   802
   intro rules and then proving equivalence by the simplifier.
hoelzl@51732
   803
hoelzl@51732
   804
 - Restructured theories in HOL-Complex_Main:
hoelzl@51732
   805
hoelzl@51732
   806
   + Moved RealDef and RComplete into Real
hoelzl@51732
   807
hoelzl@51732
   808
   + Introduced Topological_Spaces and moved theorems about

     topological spaces, filters, limits and continuity to it
hoelzl@51732
   810
hoelzl@51732
   811
   + Renamed RealVector to Real_Vector_Spaces
hoelzl@51732
   812
wenzelm@53983
   813
   + Split Lim, SEQ, Series into Topological_Spaces,

   814
     Real_Vector_Spaces, and Limits
hoelzl@51732
   815

hoelzl@51732
   818
   + Moved theorems about continuity from Deriv to Topological_Spaces
hoelzl@51732
   819
hoelzl@51732

* Nitpick:
blanchet@55889
   825

blanchet@55889
   833
  - Better support for "isar_proofs".

  - MaSh has been fined-tuned and now runs as a local server.
blanchet@51137
   835
wenzelm@54032

isar-ref manual and ~~/src/HOL/ex/Adhoc_Overloading_Examples.thy).
wenzelm@54032
   838
wenzelm@54032
   839
* Library/Polynomial.thy:
wenzelm@54032
   840
  - Use lifting for primitive definitions.
wenzelm@54032
   841
  - Explicit conversions from and to lists of coefficients, used for
wenzelm@54032
   842
    generated code.
wenzelm@54032
   843
  - Replaced recursion operator poly_rec by fold_coeffs.
wenzelm@54032
   844
  - Prefer pre-existing gcd operation for gcd.
wenzelm@54032

wenzelm@54032
   852
case_of_simps to convert function definitions between a list of

* Consolidation of library theories on product orders:
wenzelm@54032
   862
wenzelm@54032
   863
    Product_Lattice ~> Product_Order -- pointwise order on products

wenzelm@53160
   869
longer included by default. INCOMPATIBILITY, use partial_function
wenzelm@53160
   870
instead, or import theory Legacy_Mrec as a fallback.
wenzelm@53160
   871
wenzelm@53983
   872
* HOL-Algebra: Discontinued theories ~~/src/HOL/Algebra/abstract and
wenzelm@53983
   873
~~/src/HOL/Algebra/poly.  Existing theories should be based on
wenzelm@53983
   874
~~/src/HOL/Library/Polynomial instead.  The latter provides
wenzelm@53983
   875
integration with HOL's type classes for rings.  INCOMPATIBILITY.

* HOL-BNF:
wenzelm@54032
   878
  - Various improvements to BNF-based (co)datatype package, including
wenzelm@54032
   879
    new commands "primrec_new", "primcorec", and
wenzelm@54032
   880
    "datatype_new_compat", as well as documentation. See
wenzelm@54032
   881
    "datatypes.pdf" for details.
wenzelm@54032
   882
  - New "coinduction" method to avoid some boilerplate (compared to
wenzelm@54032
   883
    coinduct).
wenzelm@54032
   884
  - Renamed keywords:

*** ML ***
wenzelm@51551
   899
wenzelm@53971
   900
* Spec_Check is a Quickcheck tool for Isabelle/ML.  The ML function
wenzelm@53971
   901
"check_property" allows to check specifications of the form "ALL x y
wenzelm@53971
   902
z. prop x y z".  See also ~~/src/Tools/Spec_Check/ with its

   903
Examples.thy in particular.
wenzelm@53971
   904
wenzelm@53709
   905
* Improved printing of exception trace in Poly/ML 5.5.1, with regular
wenzelm@53709
   906
tracing output in the command transaction context instead of physical
wenzelm@53709
   907

wenzelm@53971
   910
* ML type "theory" is now immutable, without any special treatment of
wenzelm@53971
   911
drafts or linear updates (which could lead to "stale theory" errors in
wenzelm@53971
   912
the past).  Discontinued obsolete operations like Theory.copy,
wenzelm@53971
   913
Theory.checkpoint, and the auxiliary type theory_ref.  Minor
wenzelm@53971
   914
INCOMPATIBILITY.
wenzelm@53164
   915
wenzelm@51551

wenzelm@51551
   918
    Skip_Proof.prove  ~>  Goal.prove_sorry

   921
Minor INCOMPATIBILITY.
wenzelm@51703
   922
wenzelm@51717
   923
* Simplifier tactics and tools use proper Proof.context instead of
wenzelm@51717
   924
historic type simpset.  Old-style declarations like addsimps,
wenzelm@51717
   925
addsimprocs etc. operate directly on Proof.context.  Raw type simpset
wenzelm@51717
   926
retains its use as snapshot of the main Simplifier context, using
wenzelm@51717
   927
simpset_of and put_simpset on Proof.context.  INCOMPATIBILITY -- port
wenzelm@51717
   928
old tools by making them depend on (ctxt : Proof.context) instead of
wenzelm@51717
   929
(ss : simpset), then turn (simpset_of ctxt) into ctxt.
wenzelm@51717
   930
wenzelm@53971
   931
* Modifiers for classical wrappers (e.g. addWrapper, delWrapper)
wenzelm@53971
   932
operate on Proof.context instead of claset, for uniformity with addIs,
wenzelm@53971
   933
addEs, addDs etc. Note that claset_of and put_claset allow to manage
wenzelm@53971
   934
clasets separately from the context.
wenzelm@53971
   935
wenzelm@51717
   936
* Discontinued obsolete ML antiquotations @{claset} and @{simpset}.
wenzelm@51717
   937
INCOMPATIBILITY, use @{context} instead.
wenzelm@51717
   938
wenzelm@53971

wenzelm@52550
   953
wenzelm@52746

   955
document formats: dvi.gz, ps, ps.gz -- the default document format is
wenzelm@52746
   956
always pdf.
wenzelm@52743
   957
wenzelm@52053
   958

specify global resources of the JVM process run by isabelle build.
wenzelm@52053
   960
wenzelm@52116
   961

   962
to run Isabelle/Scala source files as standalone programs.
wenzelm@52116
   963
wenzelm@52439
   964
* Improved "isabelle keywords" tool (for old-style ProofGeneral
wenzelm@52439
   965
keyword tables): use Isabelle/Scala operations, which inspect outer
wenzelm@52439
   966
syntax without requiring to build sessions first.
wenzelm@52439
   967
wenzelm@53971
   968
* Sessions may be organized via 'chapter' specifications in the ROOT
wenzelm@53971
   969
file, which determines a two-level hierarchy of browser info.  The old
wenzelm@53971
   970
tree-like organization via implicit sub-session relation (with its
wenzelm@53971
   971
tendency towards erratic fluctuation of URLs) has been discontinued.
wenzelm@53971

*** General ***
wenzelm@47967

wenzelm@50126
   982
* Theorem status about oracles and unfinished/failed future proofs is
wenzelm@50126
   983
no longer printed by default, since it is incompatible with
wenzelm@50126
   984
incremental / parallel checking of the persistent document model.  ML
wenzelm@50126
   985
function Thm.peek_status may be used to inspect a snapshot of the
wenzelm@50126
   986
ongoing evaluation process.  Note that in batch mode --- notably
wenzelm@50126
   987
isabelle build --- the system ensures that future proofs of all
wenzelm@50126
   988
accessible theorems in the theory context are finished (as before).
wenzelm@50126
   989
wenzelm@49699
   990
* Configuration option show_markup controls direct inlining of markup
wenzelm@49699
   991
into the printed representation of formal entities --- notably type
wenzelm@49699
   992
and sort constraints.  This enables Prover IDE users to retrieve that
wenzelm@49699
   993
information via tooltips in the output window, for example.
wenzelm@49699
   994
wenzelm@48890
   995
* Command 'ML_file' evaluates ML text from a file directly within the
wenzelm@48890
   996
theory, without any predeclaration via 'uses' in the theory header.
wenzelm@48890
   997
wenzelm@49243
   998
* Old command 'use' command and corresponding keyword 'uses' in the
wenzelm@49243
   999
theory header are legacy features and will be discontinued soon.
wenzelm@49243
  1000
Tools that load their additional source files may imitate the
wenzelm@49243
  1001
'ML_file' implementation, such that the system can take care of
wenzelm@49243
  1002
dependencies properly.
wenzelm@49243
  1003
wenzelm@47967
  1004
* Discontinued obsolete method fastsimp / tactic fast_simp_tac, which
wenzelm@47967
  1005
is called fastforce / fast_force_tac already since Isabelle2011-1.
wenzelm@47967
  1006
wenzelm@50110
  1007
* Updated and extended "isar-ref" and "implementation" manual, reduced
wenzelm@50110
  1008
remaining material in old "ref" manual.
wenzelm@48120
  1009
wenzelm@51050
  1010
* Improved support for auxiliary contexts that indicate block structure
wenzelm@51050
  1011
for specifications.  Nesting of "context fixes ... context assumes ..."
wenzelm@49841
  1012
and "class ... context ...".
wenzelm@49841
  1013
wenzelm@50772
  1014
* Attribute "consumes" allows a negative value as well, which is
wenzelm@50778
  1015
interpreted relatively to the total number of premises of the rule in
wenzelm@50772
  1016
the target context.  This form of declaration is stable when exported
wenzelm@50772
  1017
from a nested 'context' with additional assumptions.  It is the
wenzelm@50772
  1018
preferred form for definitional packages, notably cases/rules produced
wenzelm@50772
  1019
in HOL/inductive and HOL/function.
wenzelm@50772
  1020
wenzelm@49869
  1021
* More informative error messages for Isar proof commands involving
wenzelm@49869
  1022
lazy enumerations (method applications etc.).
wenzelm@49869
  1023
wenzelm@50213
  1024
* Refined 'help' command to retrieve outer syntax commands according
wenzelm@50213

*** Prover IDE -- Isabelle/Scala/jEdit ***
wenzelm@49968
  1029
wenzelm@49968
  1030
* Parallel terminal proofs ('by') are enabled by default, likewise
wenzelm@49968
  1031
proofs that are built into packages like 'datatype', 'function'.  This
wenzelm@49968
  1032
allows to "run ahead" checking the theory specifications on the
wenzelm@49968
  1033
surface, while the prover is still crunching on internal
wenzelm@49968
  1034
justifications.  Unfinished / cancelled proofs are restarted as
wenzelm@49968
  1035
required to complete full proof checking eventually.
wenzelm@49968
  1036
wenzelm@49968
  1037
* Improved output panel with tooltips, hyperlinks etc. based on the
wenzelm@49968
  1038
same Rich_Text_Area as regular Isabelle/jEdit buffers.  Activation of
wenzelm@49968
  1039
tooltips leads to some window that supports the same recursively,
wenzelm@49968
  1040
which can lead to stacks of tooltips as the semantic document content
wenzelm@49968
  1041
is explored.  ESCAPE closes the whole stack, individual windows may be
wenzelm@49968
  1042
closed separately, or detached to become independent jEdit dockables.
wenzelm@49968
  1043
wenzelm@50717
  1044
* Improved support for commands that produce graph output: the text
wenzelm@50717
  1045
message contains a clickable area to open a new instance of the graph
wenzelm@50717
  1046
browser on demand.
wenzelm@50717
  1047
wenzelm@49968
  1048
* More robust incremental parsing of outer syntax (partial comments,
wenzelm@49968
  1049
malformed symbols).  Changing the balance of open/close quotes and
wenzelm@49968
  1050
comment delimiters works more conveniently with unfinished situations
wenzelm@49968
  1051
that frequently occur in user interaction.
wenzelm@49968
  1052
wenzelm@49968
  1053
* More efficient painting and improved reactivity when editing large
wenzelm@49968
  1054
files.  More scalable management of formal document content.
wenzelm@49968
  1055
wenzelm@50505
  1056
* Smarter handling of tracing messages: prover process pauses after
wenzelm@50505
  1057
certain number of messages per command transaction, with some user
wenzelm@50505
  1058
dialog to stop or continue.  This avoids swamping the front-end with
wenzelm@50119
  1059
potentially infinite message streams.
wenzelm@49968
  1060
wenzelm@49968
  1061
* More plugin options and preferences, based on Isabelle/Scala.  The
wenzelm@49968
  1062
jEdit plugin option panel provides access to some Isabelle/Scala
wenzelm@49968
  1063
options, including tuning parameters for editor reactivity and color
wenzelm@49968
  1064
schemes.
wenzelm@49968
  1065
wenzelm@50184
  1066
* Dockable window "Symbols" provides some editing support for Isabelle
wenzelm@50184
  1067
symbols.
wenzelm@50184
  1068
wenzelm@51082
  1069
* Dockable window "Monitor" shows ML runtime statistics.  Note that
wenzelm@51082
  1070
continuous display of the chart slows down the system.

* Improved editing support for control styles: subscript, superscript,
wenzelm@50183
  1073
bold, reset of style -- operating on single symbols or text
wenzelm@50198
  1074
selections.  Cf. keyboard shortcuts C+e DOWN/UP/RIGHT/LEFT.
wenzelm@50198
  1075
wenzelm@50198
  1076
* Actions isabelle.increase-font-size and isabelle.decrease-font-size
wenzelm@50198
  1077
adjust the main text area font size, and its derivatives for output,
wenzelm@50836
  1078
tooltips etc.  Cf. keyboard shortcuts C-PLUS and C-MINUS, which often
wenzelm@50836
  1079
need to be adapted to local keyboard layouts.
wenzelm@50183
  1080
wenzelm@50730
  1081
* More reactive completion popup by default: use \t (TAB) instead of
wenzelm@50730
  1082
\n (NEWLINE) to minimize intrusion into regular flow of editing.  See
wenzelm@50730
  1083

* Implicit check and build dialog of the specified logic session
wenzelm@50406
  1086
image.  For example, HOL, HOLCF, HOL-Nominal can be produced on
wenzelm@50406
  1087
demand, without bundling big platform-dependent heap images in the
wenzelm@50406
  1088

* Uniform Java 7 platform on Linux, Mac OS X, Windows: recent updates
wenzelm@49968
  1091
from Oracle provide better multi-platform experience.  This version is
wenzelm@49968
  1092

* Command 'export_code': relative file names are interpreted
wenzelm@50646
  1101
relatively to master directory of current theory rather than the
wenzelm@50646
  1102
rather arbitrary current working directory.  INCOMPATIBILITY.
haftmann@48371

* Discontinued obsolete attribute "COMP".  Potential INCOMPATIBILITY,
wenzelm@48205
  1105
use regular rule composition via "OF" / "THEN", or explicit proof
wenzelm@48205
  1106
structure instead.  Note that Isabelle/ML provides a variety of
wenzelm@48205
  1107
operators like COMP, INCR_COMP, COMP_INCR, which need to be applied
wenzelm@48205
  1108
with some care where this is really required.
wenzelm@48205
  1109
wenzelm@48792

* Command 'typ' supports an additional variant with explicit sort
wenzelm@48792
  1111
constraint, to infer and check the most general type conforming to a
wenzelm@51063
  1112
given sort.  Example (in HOL):
wenzelm@48792
  1113
wenzelm@48792
  1114
  typ "_ * _ * bool * unit" :: finite
wenzelm@48792

  1123
wenzelm@50646
  1124
  - Added MaSh relevance filter based on machine-learning; see the
wenzelm@50646
  1125
    Sledgehammer manual for details.
wenzelm@50646
  1126
  - Polished Isar proofs generated with "isar_proofs" option.
wenzelm@50646
  1127
  - Rationalized type encodings ("type_enc" option).
blanchet@50720
  1128
  - Renamed "kill_provers" subcommand to "kill_all".
wenzelm@50646
  1129

* Quickcheck: added an optimisation for equality premises.  It is
wenzelm@50646
  1136
switched on by default, and can be switched off by setting the
wenzelm@50646
  1137
configuration quickcheck_optimise_equality to false.

  1149
wenzelm@50646

wenzelm@50646
  1153
* The SMT solver Z3 has now by default a restricted set of directly
wenzelm@50646
  1154
supported features. For the full set of features (div/mod, nonlinear
wenzelm@50646
  1155
arithmetic, datatypes/records) with potential proof reconstruction
wenzelm@50646
  1156
failures, enable the configuration option "z3_with_extensions".  Minor
wenzelm@50646
  1157
INCOMPATIBILITY.
haftmann@49948
  1158
wenzelm@49836
  1159
* Simplified 'typedef' specifications: historical options for implicit
wenzelm@49836
  1160
set definition and alternative name have been discontinued.  The
wenzelm@49836
  1161
former behavior of "typedef (open) t = A" is now the default, but
wenzelm@49836
  1162
written just "typedef t = A".  INCOMPATIBILITY, need to adapt theories
wenzelm@49836
  1163
accordingly.
wenzelm@49836
  1164
wenzelm@50646

wenzelm@50646
  1167
wenzelm@50646

  1174
subtraction, with natural numbers and multisets as typical instances.
haftmann@49388
  1175
wenzelm@50646
  1176
* Added combinator "Option.these" with type "'a option set => 'a set".
wenzelm@50646
  1177
wenzelm@50646

  1192
* Generalized the definition of limits:
wenzelm@50646
  1193
wenzelm@50646
  1194
  - Introduced the predicate filterlim (LIM x F. f x :> G) which
wenzelm@50646
  1195
    expresses that when the input values x converge to F then the
wenzelm@50646
  1196
    output f x converges to G.
wenzelm@50646
  1197
wenzelm@50646
  1198
  - Added filters for convergence to positive (at_top) and negative
wenzelm@50646
  1199
    infinity (at_bot).
wenzelm@50646
  1200
wenzelm@50646
  1201
  - Moved infinity in the norm (at_infinity) from
wenzelm@50646
  1202
    Multivariate_Analysis to Complex_Main.
wenzelm@50646
  1203
wenzelm@50646
  1204
  - Removed real_tendsto_inf, it is superseded by "LIM x F. f x :>
wenzelm@50646

  1220
changes as follows.
wenzelm@50646

  1225
      strict_prefix ~> prefix
Christian@49145
  1226
wenzelm@50646
  1227
  - Replaced constant "postfix" by "suffixeq" with swapped argument
wenzelm@50646
  1228
    order (i.e., "postfix xs ys" is now "suffixeq ys xs") and dropped
wenzelm@50646
  1229
    old infix syntax "xs >>= ys"; use "suffixeq ys xs" instead.
wenzelm@50646
  1230
    Renamed lemmas accordingly.
wenzelm@50646
  1231
wenzelm@50646
  1232
  - Added constant "list_hembeq" for homeomorphic embedding on
wenzelm@50646
  1233
    lists. Added abbreviation "sublisteq" for special case
wenzelm@50646
  1234
    "list_hembeq (op =)".
wenzelm@50646
  1235
wenzelm@50646
  1236
  - Theory Library/Sublist no longer provides "order" and "bot" type
wenzelm@50646
  1237
    class instances for the prefix order (merely corresponding locale
wenzelm@50646
  1238
    interpretations). The type class instances are now in theory
wenzelm@50646
  1239
    Library/Prefix_Order.
wenzelm@50646
  1240
wenzelm@50646

*** Document preparation ***
wenzelm@48206
  1370
wenzelm@50646
  1371
* Dropped legacy antiquotations "term_style" and "thm_style", since
wenzelm@50646
  1372
styles may be given as arguments to "term" and "thm" already.
wenzelm@50646
  1373
Discontinued legacy styles "prem1" .. "prem19".
wenzelm@50646
  1374
wenzelm@50646
  1375
* Default LaTeX rendering for \<euro> is now based on eurosym package,
wenzelm@50646
  1376
instead of slightly exotic babel/greek.
wenzelm@48206
  1377
wenzelm@48616
  1378
* Document variant NAME may use different LaTeX entry point
wenzelm@48616
  1379
document/root_NAME.tex if that file exists, instead of the common
wenzelm@48616
  1380
document/root.tex.
wenzelm@48616
  1381
wenzelm@48657
  1382
* Simplified custom document/build script, instead of old-style

wenzelm@48992
  1387
wenzelm@50646
  1388
* The default limit for maximum number of worker threads is now 8,
wenzelm@50646
  1389
instead of 4, in correspondence to capabilities of contemporary
wenzelm@50646
  1390
hardware and Poly/ML runtime system.
wenzelm@50646
  1391
wenzelm@49869
  1392
* Type Seq.results and related operations support embedded error
wenzelm@49869
  1393
messages within lazy enumerations, and thus allow to provide
wenzelm@49869
  1394
informative errors in the absence of any usable results.
wenzelm@49869
  1395
wenzelm@48992
  1396
* Renamed Position.str_of to Position.here to emphasize that this is a
wenzelm@48992
  1397
formal device to inline positions into message text, but not
wenzelm@48992
  1398
necessarily printing visible text.

*** System ***
wenzelm@48206
  1402
wenzelm@48585
  1403
* Advanced support for Isabelle sessions and build management, see
wenzelm@48585
  1404
"system" manual for the chapter of that name, especially the "isabelle
wenzelm@51056
  1405
build" tool and its examples.  The "isabelle mkroot" tool prepares
wenzelm@51056
  1406
session root directories for use with "isabelle build", similar to
wenzelm@51056
  1407
former "isabelle mkdir" for "isabelle usedir".  Note that this affects
wenzelm@51056
  1408
document preparation as well.  INCOMPATIBILITY, isabelle usedir /
wenzelm@48736
  1409
mkdir / make are rendered obsolete.
wenzelm@48736
  1410
wenzelm@51056
  1411
* Discontinued obsolete Isabelle/build script, it is superseded by the
wenzelm@51056
  1412
regular isabelle build tool.  For example:
wenzelm@51056
  1413
wenzelm@51056
  1414
  isabelle build -s -b HOL
wenzelm@51056
  1415
wenzelm@48736
  1416
* Discontinued obsolete "isabelle makeall".
wenzelm@48585
  1417
wenzelm@48722
  1418
* Discontinued obsolete IsaMakefile and ROOT.ML files from the
wenzelm@48722
  1419
Isabelle distribution, except for rudimentary src/HOL/IsaMakefile that
wenzelm@48722
  1420
provides some traditional targets that invoke "isabelle build".  Note
wenzelm@48722
  1421
that this is inefficient!  Applications of Isabelle/HOL involving
wenzelm@48722
  1422
"isabelle make" should be upgraded to use "isabelle build" directly.
wenzelm@48722
  1423
wenzelm@48693
  1424
* The "isabelle options" tool prints Isabelle system options, as
wenzelm@48693
  1425
required for "isabelle build", for example.
wenzelm@48693
  1426
wenzelm@50646
  1427
* The "isabelle logo" tool produces EPS and PDF format simultaneously.
wenzelm@50646
  1428
Minor INCOMPATIBILITY in command-line options.
wenzelm@50646
  1429
wenzelm@50646
  1430
* The "isabelle install" tool has now a simpler command-line.  Minor
wenzelm@50646
  1431
INCOMPATIBILITY.
wenzelm@50646
  1432
wenzelm@48844
  1433
* The "isabelle components" tool helps to resolve add-on components
wenzelm@48844
  1434
that are not bundled, or referenced from a bare-bones repository
wenzelm@48844
  1435
version of Isabelle.
wenzelm@48844
  1436
wenzelm@50646
  1437
* Settings variable ISABELLE_PLATFORM_FAMILY refers to the general
wenzelm@50646
  1438
platform family: "linux", "macos", "windows".
wenzelm@50646
  1439
wenzelm@50646
  1440
* The ML system is configured as regular component, and no longer
wenzelm@50646
  1441
picked up from some surrounding directory.  Potential INCOMPATIBILITY
wenzelm@50646
  1442
for home-made settings.
wenzelm@50132
  1443
wenzelm@50701
  1444
* Improved ML runtime statistics (heap, threads, future tasks etc.).
wenzelm@50701
  1445
wenzelm@48206
  1446
* Discontinued support for Poly/ML 5.2.1, which was the last version
wenzelm@48206
  1447
without exception positions and advanced ML compiler/toplevel
wenzelm@48206
  1448
configuration.
wenzelm@48206
  1449
wenzelm@48574
  1450
* Discontinued special treatment of Proof General -- no longer guess
wenzelm@48574
  1451
PROOFGENERAL_HOME based on accidental file-system layout.  Minor
wenzelm@48574
  1452
INCOMPATIBILITY: provide PROOFGENERAL_HOME and PROOFGENERAL_OPTIONS
wenzelm@48574
  1453
settings manually, or use a Proof General version that has been
wenzelm@48574
  1454
bundled as Isabelle component.

------------------------------
wenzelm@45109
  1460
wenzelm@45593
  1461
*** General ***
wenzelm@45593
  1462
wenzelm@45614
  1463
* Prover IDE (PIDE) improvements:
wenzelm@45614
  1464
wenzelm@47585
  1465
  - more robust Sledgehammer integration (as before the sledgehammer
wenzelm@47806
  1466
    command-line needs to be typed into the source buffer)
wenzelm@45614
  1467
  - markup for bound variables
wenzelm@47806
  1468
  - markup for types of term variables (displayed as tooltips)
wenzelm@46956
  1469
  - support for user-defined Isar commands within the running session
wenzelm@47158
  1470
  - improved support for Unicode outside original 16bit range
wenzelm@47158
  1471
    e.g. glyph for \<A> (thanks to jEdit 4.5.1)
wenzelm@45614
  1472
wenzelm@47806
  1473
* Forward declaration of outer syntax keywords within the theory
wenzelm@47806
  1474
header -- minor INCOMPATIBILITY for user-defined commands.  Allow new
wenzelm@47806
  1475
commands to be used in the same theory where defined.
wenzelm@46485
  1476
wenzelm@47482
  1477
* Auxiliary contexts indicate block structure for specifications with
wenzelm@47482
  1478
additional parameters and assumptions.  Such unnamed contexts may be
wenzelm@47482
  1479
nested within other targets, like 'theory', 'locale', 'class',
wenzelm@47482
  1480
'instantiation' etc.  Results from the local context are generalized
wenzelm@47482
  1481
accordingly and applied to the enclosing target context.  Example:
wenzelm@47482
  1482
wenzelm@47482
  1483
  context
wenzelm@47482
  1484
    fixes x y z :: 'a
wenzelm@47482
  1485
    assumes xy: "x = y" and yz: "y = z"
wenzelm@47482
  1486
  begin
wenzelm@47482
  1487
wenzelm@47482
  1488
  lemma my_trans: "x = z" using xy yz by simp
wenzelm@47482
  1489
wenzelm@47482
  1490
  end
wenzelm@47482
  1491
wenzelm@47482
  1492
  thm my_trans
wenzelm@47482
  1493
wenzelm@47482
  1494
The most basic application is to factor-out context elements of
wenzelm@47482
  1495
several fixes/assumes/shows theorem statements, e.g. see
wenzelm@47482
  1496
~~/src/HOL/Isar_Examples/Group_Context.thy
wenzelm@47482
  1497
wenzelm@47482
  1498
Any other local theory specification element works within the "context
wenzelm@47482
  1499
... begin ... end" block as well.
wenzelm@47482
  1500
wenzelm@47484
  1501
* Bundled declarations associate attributed fact expressions with a
wenzelm@47484
  1502
given name in the context.  These may be later included in other
wenzelm@47484
  1503
contexts.  This allows to manage context extensions casually, without
wenzelm@47855
  1504
the logical dependencies of locales and locale interpretation.  See
wenzelm@47855
  1505
commands 'bundle', 'include', 'including' etc. in the isar-ref manual.
wenzelm@47484
  1506
wenzelm@47829
  1507
* Commands 'lemmas' and 'theorems' allow local variables using 'for'
wenzelm@47829
  1508
declaration, and results are standardized before being stored.  Thus
wenzelm@47829
  1509
old-style "standard" after instantiation or composition of facts
wenzelm@47829
  1510
becomes obsolete.  Minor INCOMPATIBILITY, due to potential change of
wenzelm@47829
  1511
indices of schematic variables.
wenzelm@47829
  1512
wenzelm@47829
  1513
* Rule attributes in local theory declarations (e.g. locale or class)
wenzelm@47829
  1514
are now statically evaluated: the resulting theorem is stored instead
wenzelm@47829
  1515
of the original expression.  INCOMPATIBILITY in rare situations, where
wenzelm@47829
  1516
the historic accident of dynamic re-evaluation in interpretations
wenzelm@47829
  1517
etc. was exploited.
wenzelm@47829
  1518
wenzelm@47829
  1519
* New tutorial "Programming and Proving in Isabelle/HOL"
wenzelm@47829
  1520
("prog-prove").  It completely supersedes "A Tutorial Introduction to
wenzelm@47829
  1521
Structured Isar Proofs" ("isar-overview"), which has been removed.  It
wenzelm@47829
  1522
also supersedes "Isabelle/HOL, A Proof Assistant for Higher-Order
wenzelm@47829
  1523
Logic" as the recommended beginners tutorial, but does not cover all
wenzelm@47829
  1524
of the material of that old tutorial.
wenzelm@47829
  1525
wenzelm@47829
  1526
* Updated and extended reference manuals: "isar-ref",
wenzelm@47829
  1527
"implementation", "system"; reduced remaining material in old "ref"
wenzelm@47829
  1528
manual.

wenzelm@47829
  1531
*** Pure ***
wenzelm@47829
  1532
wenzelm@46976
  1533
* Command 'definition' no longer exports the foundational "raw_def"
wenzelm@46976
  1534
into the user context.  Minor INCOMPATIBILITY, may use the regular
wenzelm@46976
  1535
"def" result with attribute "abs_def" to imitate the old version.
wenzelm@46976
  1536
wenzelm@47855
  1537
* Attribute "abs_def" turns an equation of the form "f x y == t" into
wenzelm@47855
  1538
"f == %x y. t", which ensures that "simp" or "unfold" steps always
wenzelm@47855
  1539
expand it.  This also works for object-logic equality.  (Formerly
wenzelm@47855
  1540
undocumented feature.)
wenzelm@47855
  1541
wenzelm@47856
  1542
* Sort constraints are now propagated in simultaneous statements, just
wenzelm@47856
  1543
like type constraints.  INCOMPATIBILITY in rare situations, where
wenzelm@47856
  1544
distinct sorts used to be assigned accidentally.  For example:
wenzelm@47856
  1545
wenzelm@47856
  1546
  lemma "P (x::'a::foo)" and "Q (y::'a::bar)"  -- "now illegal"
wenzelm@47856
  1547
wenzelm@47856
  1548
  lemma "P (x::'a)" and "Q (y::'a::bar)"
wenzelm@47856
  1549
    -- "now uniform 'a::bar instead of default sort for first occurrence (!)"
wenzelm@47856
  1550
wenzelm@47856
  1551
* Rule composition via attribute "OF" (or ML functions OF/MRS) is more
wenzelm@47856
  1552
tolerant against multiple unifiers, as long as the final result is
wenzelm@47856
  1553
unique.  (As before, rules are composed in canonical right-to-left
wenzelm@47856
  1554
order to accommodate newly introduced premises.)
wenzelm@47856
  1555
wenzelm@47806
  1556
* Renamed some inner syntax categories:
wenzelm@47806
  1557
wenzelm@47806
  1558
    num ~> num_token
wenzelm@47806
  1559
    xnum ~> xnum_token
wenzelm@47806
  1560
    xstr ~> str_token
wenzelm@47806
  1561
wenzelm@47806
  1562
Minor INCOMPATIBILITY.  Note that in practice "num_const" or
wenzelm@47806
  1563
"num_position" etc. are mainly used instead (which also include
wenzelm@47806
  1564
position information via constraints).
wenzelm@47806
  1565
wenzelm@47829
  1566
* Simplified configuration options for syntax ambiguity: see
wenzelm@47829
  1567
"syntax_ambiguity_warning" and "syntax_ambiguity_limit" in isar-ref
wenzelm@47829
  1568
manual.  Minor INCOMPATIBILITY.
wenzelm@47829
  1569
wenzelm@47856
  1570
* Discontinued configuration option "syntax_positions": atomic terms
wenzelm@47856
  1571
in parse trees are always annotated by position constraints.
wenzelm@45134
  1572
wenzelm@47464
  1573
* Old code generator for SML and its commands 'code_module',
wenzelm@45383
  1574
'code_library', 'consts_code', 'types_code' have been discontinued.
haftmann@46028
  1575
Use commands of the generic code generator instead.  INCOMPATIBILITY.
wenzelm@45383
  1576
wenzelm@47464
  1577
* Redundant attribute "code_inline" has been discontinued. Use
wenzelm@47464
  1578
"code_unfold" instead.  INCOMPATIBILITY.
wenzelm@47464
  1579
wenzelm@47464
  1580
* Dropped attribute "code_unfold_post" in favor of the its dual
wenzelm@47464
  1581
"code_abbrev", which yields a common pattern in definitions like
haftmann@46028
  1582
haftmann@46028
  1583
  definition [code_abbrev]: "f = t"
haftmann@46028
  1584
haftmann@46028
  1585
INCOMPATIBILITY.
wenzelm@45383
  1586
wenzelm@47856
  1587
* Obsolete 'types' command has been discontinued.  Use 'type_synonym'
wenzelm@47856
  1588
instead.  INCOMPATIBILITY.
wenzelm@47856
  1589
wenzelm@47856
  1590
* Discontinued old "prems" fact, which used to refer to the accidental
wenzelm@47856
  1591
collection of foundational premises in the context (already marked as
wenzelm@47856
  1592
legacy since Isabelle2011).

* Type 'a set is now a proper type constructor (just as before
wenzelm@47464
  1598
Isabelle2008).  Definitions mem_def and Collect_def have disappeared.
wenzelm@47464
  1599
Non-trivial INCOMPATIBILITY.  For developments keeping predicates and
wenzelm@47855
  1600
sets separate, it is often sufficient to rephrase some set S that has
wenzelm@47855
  1601
been accidentally used as predicates by "%x. x : S", and some
wenzelm@47855
  1602
predicate P that has been accidentally used as set by "{x. P x}".
wenzelm@47855
  1603
Corresponding proofs in a first step should be pruned from any
wenzelm@47855
  1604
tinkering with former theorems mem_def and Collect_def as far as
wenzelm@47855
  1605
possible.
wenzelm@47855
  1606
wenzelm@47855
  1607
For developments which deliberately mix predicates and sets, a
wenzelm@47464
  1608
planning step is necessary to determine what should become a predicate
wenzelm@47464
  1609
and what a set.  It can be helpful to carry out that step in
wenzelm@47464
  1610
Isabelle2011-1 before jumping right into the current release.
wenzelm@47464
  1611
wenzelm@47855
  1612
* Code generation by default implements sets as container type rather
wenzelm@47855
  1613
than predicates.  INCOMPATIBILITY.
wenzelm@47855
  1614
wenzelm@47855
  1615
* New type synonym 'a rel = ('a * 'a) set
wenzelm@47855
  1616
wenzelm@47464
  1617
* The representation of numerals has changed.  Datatype "num"
wenzelm@47464
  1618
represents strictly positive binary numerals, along with functions
wenzelm@47464
  1619
"numeral :: num => 'a" and "neg_numeral :: num => 'a" to represent
wenzelm@47855
  1620
positive and negated numeric literals, respectively.  See also
wenzelm@47855
  1621
definitions in ~~/src/HOL/Num.thy.  Potential INCOMPATIBILITY, some
wenzelm@47855
  1622
user theories may require adaptations as follows:

  - Theorems with number_ring or number_semiring constraints: These
huffman@47108
  1625
    classes are gone; use comm_ring_1 or comm_semiring_1 instead.
huffman@47108
  1626
huffman@47108
  1627
  - Theories defining numeric types: Remove number, number_semiring,
huffman@47108
  1628
    and number_ring instances. Defer all theorems about numerals until
huffman@47108
  1629
    after classes one and semigroup_add have been instantiated.
huffman@47108
  1630
huffman@47108

  - Numeral-only simp rules: Replace each rule having a "number_of v"
huffman@47108
  1632
    pattern with two copies, one for numeral and one for neg_numeral.
huffman@47108
  1633
huffman@47108
  1634
  - Theorems about subclasses of semiring_1 or ring_1: These classes
huffman@47108
  1635
    automatically support numerals now, so more simp rules and
huffman@47108
  1636
    simprocs may now apply within the proof.

  1641
* Transfer: New package intended to generalize the existing
wenzelm@47855
  1642
"descending" method and related theorem attributes from the Quotient
wenzelm@47855
  1643
package.  (Not all functionality is implemented yet, but future
wenzelm@47855
  1644
development will focus on Transfer as an eventual replacement for the
wenzelm@47855
  1645
corresponding parts of the Quotient package.)
wenzelm@47809
  1646
wenzelm@47809
  1647
  - transfer_rule attribute: Maintains a collection of transfer rules,
wenzelm@47809
  1648
    which relate constants at two different types. Transfer rules may
wenzelm@47809
  1649
    relate different type instances of the same polymorphic constant,
wenzelm@47809
  1650
    or they may relate an operation on a raw type to a corresponding
wenzelm@47809
  1651
    operation on an abstract type (quotient or subtype). For example:
wenzelm@47809
  1652
wenzelm@47809
  1653
    ((A ===> B) ===> list_all2 A ===> list_all2 B) map map
wenzelm@47809
  1654
    (cr_int ===> cr_int ===> cr_int) (%(x,y) (u,v). (x+u, y+v)) plus_int
wenzelm@47809
  1655
wenzelm@47809
  1656
  - transfer method: Replaces a subgoal on abstract types with an
wenzelm@47809
  1657
    equivalent subgoal on the corresponding raw types. Constants are
wenzelm@47809
  1658
    replaced with corresponding ones according to the transfer rules.
wenzelm@47809
  1659
    Goals are generalized over all free variables by default; this is
huffman@47851
  1660
    necessary for variables whose types change, but can be overridden
wenzelm@47855
  1661
    for specific variables with e.g. "transfer fixing: x y z".  The
wenzelm@47809
  1662
    variant transfer' method allows replacing a subgoal with one that
wenzelm@47809
  1663
    is logically stronger (rather than equivalent).
wenzelm@47809
  1664
wenzelm@47809
  1665
  - relator_eq attribute: Collects identity laws for relators of
wenzelm@47809
  1666
    various type constructors, e.g. "list_all2 (op =) = (op =)".  The
wenzelm@47809
  1667
    transfer method uses these lemmas to infer transfer rules for
wenzelm@47809
  1668
    non-polymorphic constants on the fly.
wenzelm@47809
  1669
wenzelm@47809
  1670
  - transfer_prover method: Assists with proving a transfer rule for a
wenzelm@47809
  1671
    new constant, provided the constant is defined in terms of other
wenzelm@47809
  1672
    constants that already have transfer rules. It should be applied
wenzelm@47809
  1673
    after unfolding the constant definitions.

wenzelm@47809

huffman@47851
  1678
* Lifting: New package intended to generalize the quotient_definition
huffman@47851
  1679
facility of the Quotient package; designed to work with Transfer.
wenzelm@47809
  1680
wenzelm@47809
  1681
  - lift_definition command: Defines operations on an abstract type in
wenzelm@47809
  1682
    terms of a corresponding operation on a representation
wenzelm@47809
  1683
    type.  Example syntax:
wenzelm@47809
  1684
wenzelm@47809
  1685
    lift_definition dlist_insert :: "'a => 'a dlist => 'a dlist"
wenzelm@47809
  1686
      is List.insert
wenzelm@47809
  1687
wenzelm@47809
  1688
    Users must discharge a respectfulness proof obligation when each
wenzelm@47809
  1689
    constant is defined. (For a type copy, i.e. a typedef with UNIV,
wenzelm@47809
  1690
    the proof is discharged automatically.) The obligation is
wenzelm@47809
  1691
    presented in a user-friendly, readable form; a respectfulness
wenzelm@47809
  1692
    theorem in the standard format and a transfer rule are generated
wenzelm@47809
  1693
    by the package.
wenzelm@47809
  1694
wenzelm@47809
  1695
  - Integration with code_abstype: For typedefs (e.g. subtypes
wenzelm@47809
  1696
    corresponding to a datatype invariant, such as dlist),
wenzelm@47809
  1697
    lift_definition generates a code certificate theorem and sets up
wenzelm@47809
  1698
    code generation for each constant.
wenzelm@47809
  1699
wenzelm@47809
  1700
  - setup_lifting command: Sets up the Lifting package to work with a
wenzelm@47809
  1701
    user-defined type. The user must provide either a quotient theorem
wenzelm@47809
  1702
    or a type_definition theorem.  The package configures transfer
wenzelm@47809
  1703
    rules for equality and quantifiers on the type, and sets up the
wenzelm@47809
  1704
    lift_definition command to work with the type.
wenzelm@47809
  1705
wenzelm@47809
  1706
  - Usage examples: See Quotient_Examples/Lift_DList.thy,
huffman@47851
  1707
    Quotient_Examples/Lift_RBT.thy, Quotient_Examples/Lift_FSet.thy,
huffman@47851
  1708
    Word/Word.thy and Library/Float.thy.
wenzelm@47809
  1709
wenzelm@47809
  1710
* Quotient package:
wenzelm@47809
  1711
wenzelm@47809
  1712
  - The 'quotient_type' command now supports a 'morphisms' option with
wenzelm@47809
  1713
    rep and abs functions, similar to typedef.
wenzelm@47809
  1714
wenzelm@47809
  1715
  - 'quotient_type' sets up new types to work with the Lifting and
wenzelm@47809
  1716
    Transfer packages, as with 'setup_lifting'.
wenzelm@47809
  1717
wenzelm@47809
  1718
  - The 'quotient_definition' command now requires the user to prove a
wenzelm@47809
  1719
    respectfulness property at the point where the constant is
wenzelm@47809
  1720
    defined, similar to lift_definition; INCOMPATIBILITY.
wenzelm@47809
  1721
wenzelm@47809
  1722
  - Renamed predicate 'Quotient' to 'Quotient3', and renamed theorems
wenzelm@47809
  1723
    accordingly, INCOMPATIBILITY.
wenzelm@47809
  1724
wenzelm@47809
  1725
* New diagnostic command 'find_unused_assms' to find potentially
wenzelm@47809
  1726
superfluous assumptions in theorems using Quickcheck.
wenzelm@47809
  1727
wenzelm@47809
  1728
* Quickcheck:
wenzelm@47809
  1729
wenzelm@47809
  1730
  - Quickcheck returns variable assignments as counterexamples, which
wenzelm@47809
  1731
    allows to reveal the underspecification of functions under test.
wenzelm@47809
  1732
    For example, refuting "hd xs = x", it presents the variable
wenzelm@47809
  1733
    assignment xs = [] and x = a1 as a counterexample, assuming that
wenzelm@47809
  1734
    any property is false whenever "hd []" occurs in it.
wenzelm@47809
  1735
wenzelm@47809
  1736
    These counterexample are marked as potentially spurious, as
wenzelm@47809
  1737
    Quickcheck also returns "xs = []" as a counterexample to the
wenzelm@47809
  1738
    obvious theorem "hd xs = hd xs".
wenzelm@47809
  1739
wenzelm@47809
  1740
    After finding a potentially spurious counterexample, Quickcheck
wenzelm@47809
  1741
    continues searching for genuine ones.
wenzelm@47809
  1742
wenzelm@47809
  1743
    By default, Quickcheck shows potentially spurious and genuine
wenzelm@47809
  1744
    counterexamples. The option "genuine_only" sets quickcheck to only
wenzelm@47809
  1745
    show genuine counterexamples.
wenzelm@47809
  1746
wenzelm@47809
  1747
  - The command 'quickcheck_generator' creates random and exhaustive
wenzelm@47809
  1748
    value generators for a given type and operations.
wenzelm@47809
  1749
wenzelm@47809
  1750
    It generates values by using the operations as if they were
wenzelm@47809
  1751
    constructors of that type.
wenzelm@47809
  1752
wenzelm@47809
  1753
  - Support for multisets.
wenzelm@47809
  1754
wenzelm@47809
  1755
  - Added "use_subtype" options.
wenzelm@47809
  1756
wenzelm@47809
  1757
  - Added "quickcheck_locale" configuration to specify how to process
wenzelm@47809
  1758
    conjectures in a locale context.
wenzelm@47809
  1759
wenzelm@47855
  1760
* Nitpick: Fixed infinite loop caused by the 'peephole_optim' option
wenzelm@47855
  1761
and affecting 'rat' and 'real'.
wenzelm@47809
  1762
wenzelm@47809
  1763
* Sledgehammer:
wenzelm@47809
  1764
  - Integrated more tightly with SPASS, as described in the ITP 2012
wenzelm@47809
  1765
    paper "More SPASS with Isabelle".
wenzelm@47809
  1766
  - Made it try "smt" as a fallback if "metis" fails or times out.
wenzelm@47809
  1767
  - Added support for the following provers: Alt-Ergo (via Why3 and
wenzelm@47809
  1768
    TFF1), iProver, iProver-Eq.
wenzelm@47809
  1769
  - Sped up the minimizer.
wenzelm@47809
  1770
  - Added "lam_trans", "uncurry_aliases", and "minimize" options.
wenzelm@47809
  1771
  - Renamed "slicing" ("no_slicing") option to "slice" ("dont_slice").
wenzelm@47809
  1772
  - Renamed "sound" option to "strict".
wenzelm@47809
  1773
wenzelm@47855
  1774
* Metis: Added possibility to specify lambda translations scheme as a
wenzelm@47855
  1775
parenthesized argument (e.g., "by (metis (lifting) ...)").
wenzelm@47855
  1776
wenzelm@47855
  1777
* SMT: Renamed "smt_fixed" option to "smt_read_only_certificates".
wenzelm@47855
  1778
wenzelm@47855
  1779
* Command 'try0': Renamed from 'try_methods'. INCOMPATIBILITY.
wenzelm@47809
  1780
wenzelm@47856
  1781
* New "case_product" attribute to generate a case rule doing multiple
wenzelm@47856
  1782
case distinctions at the same time.  E.g.
wenzelm@47856
  1783
wenzelm@47856
  1784
  list.exhaust [case_product nat.exhaust]
wenzelm@47856
  1785
wenzelm@47856
  1786
produces a rule which can be used to perform case distinction on both
wenzelm@47856
  1787
a list and a nat.
wenzelm@47856
  1788
wenzelm@47809
  1789
* New "eventually_elim" method as a generalized variant of the
wenzelm@47855
  1790
eventually_elim* rules.  Supports structured proofs.
wenzelm@47855
  1791
wenzelm@47702
  1792
* Typedef with implicit set definition is considered legacy.  Use
wenzelm@47702
  1793
"typedef (open)" form instead, which will eventually become the
wenzelm@47702
  1794
default.
wenzelm@47702
  1795
wenzelm@47856
  1796
* Record: code generation can be switched off manually with
wenzelm@47856
  1797
wenzelm@47856
  1798
  declare [[record_coden = false]]  -- "default true"
wenzelm@47856
  1799
wenzelm@47856
  1800
* Datatype: type parameters allow explicit sort constraints.
wenzelm@47856
  1801
wenzelm@47855
  1802
* Concrete syntax for case expressions includes constraints for source
wenzelm@47855
  1803
positions, and thus produces Prover IDE markup for its bindings.
wenzelm@47855
  1804
INCOMPATIBILITY for old-style syntax translations that augment the
wenzelm@47855
  1805
pattern notation; e.g. see src/HOL/HOLCF/One.thy for translations of
wenzelm@47855
  1806
one_case.
wenzelm@47855
  1807
wenzelm@47855
  1808
* Clarified attribute "mono_set": pure declaration without modifying
wenzelm@47855
  1809
the result of the fact expression.
wenzelm@47855
  1810
haftmann@46752
  1811
* More default pred/set conversions on a couple of relation operations
wenzelm@47464
  1812
and predicates.  Added powers of predicate relations.  Consolidation
wenzelm@47464
  1813

wenzelm@47464
  1824
See theory "Relation" for examples for making use of pred/set

  1860
and corresponding theorem names:
wenzelm@47464
  1861
haftmann@47549
  1862
  - Renamed constant rel_comp to relcomp.
wenzelm@47464

simpler, and more scalable.  Requires a proof bundle, which is
wenzelm@47855
  2215

* Session HOL-Word: New proof method "word_bitwise" for splitting
wenzelm@47809
  2265
machine word equalities and inequalities into logical circuits,
wenzelm@47809
  2266
defined in HOL/Word/WordBitwise.thy.  Supports addition, subtraction,
wenzelm@47809
  2267
multiplication, shifting by constants, bitwise operators and numeric
wenzelm@47809
  2268
constants.  Requires fixed-length word types, not 'a word.  Solves
wenzelm@47854
  2269
many standard word identities outright and converts more into first
wenzelm@47809
  2270
order problems amenable to blast or similar.  See also examples in

* Session HOL-Probability: Introduced the type "'a measure" to
wenzelm@47807
  2274
represent measures, this replaces the records 'a algebra and 'a
wenzelm@47807
  2275
measure_space.  The locales based on subset_class now have two
wenzelm@47856
  2276
locale-parameters the space \<Omega> and the set of measurable sets M.
wenzelm@47856
  2277
The product of probability spaces uses now the same constant as the
wenzelm@47856
  2278
finite product of sigma-finite measure spaces "PiM :: ('i => 'a)
wenzelm@47807
  2279
measure".  Most constants are defined now outside of locales and gain
wenzelm@47807
  2280
an additional parameter, like null_sets, almost_eventually or \<mu>'.
wenzelm@47807
  2281
Measure space constructions for distributions and densities now got
wenzelm@47807
  2282
their own constants distr and density.  Instead of using locales to
wenzelm@47807
  2283
describe measure spaces with a finite space, the measure count_space
wenzelm@47807
  2284
and point_measure is introduced.  INCOMPATIBILITY.

from a minor keyword introduced via theory header declaration.
wenzelm@46948
  2469
wenzelm@46961

Outer_Syntax.command_spec from a major keyword introduced via theory
wenzelm@46961
  2472
header declaration; it can be passed to Outer_Syntax.command etc.

wenzelm@46992
  2476
/ Attrib.empty_binding, the result is not registered as user-level
wenzelm@46992
  2477
fact.  The Local_Theory.define_internal variant allows to specify a
wenzelm@46992
  2478
non-empty name (used for the foundation in the background theory),
wenzelm@46992
  2479
while omitting the fact binding in the user-context.  Potential
wenzelm@46992
  2480
INCOMPATIBILITY for derived definitional packages: need to specify
wenzelm@46992
  2481
naming policy for primitive definitions more explicitly.
wenzelm@46916
  2482
wenzelm@46497
  2483

conformance with similar operations in structure Term and Logic.
wenzelm@46497
  2485
wenzelm@45592
  2486
* Antiquotation @{attributes [...]} embeds attribute source
wenzelm@45592
  2487
representation into the ML text, which is particularly useful with

  2488
declarations like Local_Theory.note.

wenzelm@45293

* USER_HOME settings variable points to cross-platform user home
wenzelm@47661
  2516
directory, which coincides with HOME on POSIX systems only.  Likewise,
wenzelm@47661
  2517
the Isabelle path specification "~" now expands to $USER_HOME, instead
wenzelm@47661
  2518
of former $HOME.  A different default for USER_HOME may be set
wenzelm@47661
  2519
explicitly in shell environment, before Isabelle settings are
wenzelm@47661
  2520
evaluated.  Minor INCOMPATIBILITY: need to adapt Isabelle path where
wenzelm@47661
  2521
the generic user home was intended.
wenzelm@47661
  2522
wenzelm@47807
  2523
* ISABELLE_HOME_WINDOWS refers to ISABELLE_HOME in windows file name

  2524
notation, which is useful for the jEdit file browser, for example.
wenzelm@47807

*** General ***
wenzelm@41703
  2535
wenzelm@44760

* Improved Isabelle/jEdit Prover IDE (PIDE), which can be invoked as
wenzelm@44968
  2537
"isabelle jedit" or "ISABELLE_HOME/Isabelle" on the command line.
wenzelm@44760

wenzelm@44777
  2539
  - Management of multiple theory files directly from the editor
wenzelm@44760
  2540
    buffer store -- bypassing the file-system (no requirement to save
wenzelm@44760
  2541
    files for checking).
wenzelm@44760
  2542
wenzelm@44777
  2543
  - Markup of formal entities within the text buffer, with semantic
wenzelm@44760
  2544
    highlighting, tooltips and hyperlinks to jump to defining source
wenzelm@44760
  2545
    positions.
wenzelm@44760
  2546
wenzelm@44777
  2547
  - Improved text rendering, with sub/superscripts in the source
wenzelm@44777
  2548
    buffer (including support for copy/paste wrt. output panel, HTML
wenzelm@44777
  2549
    theory output and other non-Isabelle text boxes).
wenzelm@44777
  2550
wenzelm@44777
  2551
  - Refined scheduling of proof checking and printing of results,
wenzelm@44760
  2552
    based on interactive editor view.  (Note: jEdit folding and
wenzelm@44760
  2553
    narrowing allows to restrict buffer perspectives explicitly.)
wenzelm@44760
  2554
wenzelm@44777
  2555
  - Reduced CPU performance requirements, usable on machines with few
wenzelm@44760
  2556
    cores.
wenzelm@44760
  2557
wenzelm@44777
  2558
  - Reduced memory requirements due to pruning of unused document
wenzelm@44760
  2559
    versions (garbage collection).

See also ~~/src/Tools/jEdit/README.html for further information,

  2562
including some remaining limitations.
wenzelm@44760
  2563
wenzelm@44800
  2564
* Theory loader: source files are exclusively located via the master
wenzelm@44800
  2565
directory of each theory node (where the .thy file itself resides).
wenzelm@44800
  2566
The global load path (such as src/HOL/Library) has been discontinued.
wenzelm@44800
  2567
Note that the path element ~~ may be used to reference theories in the
wenzelm@44800
  2568
Isabelle home folder -- for instance, "~~/src/HOL/Library/FuncSet".
wenzelm@44800
  2569
INCOMPATIBILITY.
wenzelm@44800
  2570
wenzelm@41955
  2571
* Theory loader: source files are identified by content via SHA1
wenzelm@41955
  2572
digests.  Discontinued former path/modtime identification and optional
wenzelm@41955
  2573
ISABELLE_FILE_IDENT plugin scripts.
wenzelm@41955
  2574
wenzelm@41703
  2575
* Parallelization of nested Isar proofs is subject to
wenzelm@41703
  2576
Goal.parallel_proofs_threshold (default 100).  See also isabelle
wenzelm@41703
  2577
usedir option -Q.
wenzelm@41703
  2578
wenzelm@42669
  2579
* Name space: former unsynchronized references are now proper
wenzelm@42669
  2580
configuration options, with more conventional names:
wenzelm@42669
  2581
wenzelm@42669
  2582
  long_names   ~> names_long
wenzelm@42669
  2583
  short_names  ~> names_short

  2584
  unique_names ~> names_unique
wenzelm@42669
  2585
wenzelm@42669
  2586
Minor INCOMPATIBILITY, need to declare options in context like this:
wenzelm@42669
  2587
wenzelm@42669
  2588
  declare [[names_unique = false]]
wenzelm@42358
  2589
wenzelm@42502
  2590
* Literal facts `prop` may contain dummy patterns, e.g. `_ = _`.  Note
wenzelm@42502
  2591
that the result needs to be unique, which means fact specifications
wenzelm@42502
  2592
may have to be refined after enriching a proof context.
wenzelm@42502
  2593
wenzelm@44800
  2594
* Attribute "case_names" has been refined: the assumptions in each case
wenzelm@44800
  2595
can be named now by following the case name with [name1 name2 ...].
wenzelm@44800
  2596
wenzelm@44968
  2597
* Isabelle/Isar reference manual has been updated and extended:
wenzelm@44968
  2598
  - "Synopsis" provides a catalog of main Isar language concepts.
wenzelm@44968
  2599
  - Formal references in syntax diagrams, via @{rail} antiquotation.
wenzelm@44968
  2600
