* Simplified outer syntax: uniform category "name" includes long |
24 |
identifiers. Former "xname" / "nameref" / "name reference" has been |
|
25 |
discontinued. |
|
26 |
||
62807 | 27 |
* Mixfix annotations support general block properties, with syntax |
28 |
"(\<open>x=a y=b z \<dots>\<close>". Notable property names are "indent", "consistent", |
|
29 |
"unbreakable", "markup". The existing notation "(DIGITS" is equivalent |
|
30 |
to "(\<open>indent=DIGITS\<close>". The former notation "(00" for unbreakable blocks |
|
31 |
is superseded by "(\<open>unbreabable\<close>" --- rare INCOMPATIBILITY. |
|
62789 | 32 |
|
62440 | 33 |
* New symbol \<circle>, e.g. for temporal operator. |
34 |
||
62453 | 35 |
* Old 'header' command is no longer supported (legacy since |
36 |
Isabelle2015). |
|
37 |
||
63273 | 38 |
* Command 'bundle' provides a local theory target to define a bundle |
39 |
from the body of specification commands (such as 'declare', |
|
40 |
'declaration', 'notation', 'lemmas', 'lemma'). For example: |
|
41 |
||
42 |
bundle foo |
|
43 |
begin |
|
44 |
declare a [simp] |
|
45 |
declare b [intro] |
|
46 |
end |
|
63272 | 47 |
|
63282 | 48 |
* Command 'unbundle' is like 'include', but works within a local theory |
49 |
context. Unlike "context includes ... begin", the effect of 'unbundle' |
|
50 |
on the target context persists, until different declarations are given. |
|
51 |
||
63383 | 52 |
* Proof method "blast" is more robust wrt. corner cases of Pure |
53 |
statements without object-logic judgment. |
|

||
62440 | 55 |
|
62904 | 56 |
*** Prover IDE -- Isabelle/Scala/jEdit *** |
57 |
||
63135 | 58 |
* Cartouche abbreviations work both for " and ` to accomodate typical |
59 |
situations where old ASCII notation may be updated. |
|
60 |
||
63022 | 61 |
* IDE support for the Isabelle/Pure bootstrap process, with the |
62 |
following independent stages: |
|
63 |
||
64 |
src/Pure/ROOT0.ML |
|
65 |
src/Pure/ROOT.ML |
|
66 |
src/Pure/Pure.thy |
|
67 |
src/Pure/ML_Bootstrap.thy |
|
68 |
||
69 |
The ML ROOT files act like quasi-theories in the context of theory |
|
70 |
ML_Bootstrap: this allows continuous checking of all loaded ML files. |
|
71 |
The theory files are presented with a modified header to import Pure |
|
72 |
from the running Isabelle instance. Results from changed versions of |
|
73 |
each stage are *not* propagated to the next stage, and isolated from the |
|
74 |
actual Isabelle/Pure that runs the IDE itself. The sequential |
|
63307 | 75 |
dependencies of the above files are only observed for batch build. |

|
92 |
||
93 |
* Commands 'finally' and 'ultimately' used to expose the result as |

INCOMPATIBILITY, use more explicit means to refer to facts in Isar. |

* Command 'define' introduces a local (non-polymorphic) definition, with |

optional abstraction over local parameters. The syntax resembles |

63043 | 113 |
'definition' and 'obtain'. It fits better into the Isar language than |

|
124 |

63259 | 125 |

126 |
"method_facts". This is particularly useful for Eisbach method |
|

definitions. |
|
128 |
||

(use facts in simp) |

62253 | 612 |
Isabelle/ML and official Standard ML. Option "ML_debugger" and commands |
613 |
'ML_file_debug', 'ML_file_no_debug', 'SML_file_debug', |
|
614 |
'SML_file_no_debug' control compilation of sources with or without |
|
615 |
debugging information. The Debugger panel allows to set breakpoints (via |
|
616 |
context menu), step through stopped threads, evaluate local ML |
|
617 |
expressions etc. At least one Debugger view needs to be active to have |
|
618 |
any effect on the running ML program. |

60984 | 619 |

* The State panel manages explicit proof state output, with dynamic |
621 |
auto-update according to cursor movement. Alternatively, the jEdit |

action "isabelle.update-state" (shortcut S+ENTER) triggers manual |
|
623 |
update. |
|
61729 | 624 |

* The Output panel no longer shows proof state output by default, to |

avoid GUI overcrowding. INCOMPATIBILITY, use the State panel instead or |

|
61215 | 628 |
|
61803 | 629 |
* The text overview column (status of errors, warnings etc.) is updated |
630 |
asynchronously, leading to much better editor reactivity. Moreover, the |
|
631 |
full document node content is taken into account. The width of the |
|
632 |
column is scaled according to the main text area font, for improved |
|
633 |
visibility. |
|
634 |
||
635 |
* The main text area no longer changes its color hue in outdated |
|
636 |
situations. The text overview column takes over the role to indicate |
|
637 |
unfinished edits in the PIDE pipeline. This avoids flashing text display |
|
638 |
due to ad-hoc updates by auxiliary GUI components, such as the State |
|
639 |
panel. |

The local assumptions are bound to the name "that". The result is |
761 |
exported from context of the statement as usual. The above roughly |
|
60414 | 762 |
corresponds to a raw proof block like this: |

* Assumptions ('assume', 'presume') allow structured rule statements |
775 |
using 'if' and 'for', similar to 'have' etc. above. For example: |
|
61658 | 776 |
|
777 |
assume result: "C x y" |
|
778 |
if "A x" and "B y" |
|
779 |
for x :: 'a and y :: 'a |
|
780 |
||
781 |
This assumes "\<And>x y::'a. A x \<Longrightarrow> B y \<Longrightarrow> C x y" and produces a general |
|
782 |
result as usual: "A ?x \<Longrightarrow> B ?y \<Longrightarrow> C ?x ?y". |
|
783 |
||
784 |
Vacuous quantification in assumptions is omitted, i.e. a for-context |
|
785 |
only effects propositions according to actual use of variables. For |
|
786 |
example: |
|
787 |
||
788 |
assume "A x" and "B y" for x and y |
|
789 |
||
790 |
is equivalent to: |
|
791 |
||
792 |
assume "\<And>x. A x" and "\<And>y. B y" |
|
793 |
||
60595 | 794 |
* The meaning of 'show' with Pure rule statements has changed: premises |
795 |
are treated in the sense of 'assume', instead of 'presume'. This means, |
|
62205 | 796 |
a goal like "\<And>x. A x \<Longrightarrow> B x \<Longrightarrow> C x" can be solved completely as |
797 |
follows: |
|
60595 | 798 |
|
799 |
show "\<And>x. A x \<Longrightarrow> B x \<Longrightarrow> C x" |
|
800 |
||
801 |
or: |
|
802 |
||
803 |
show "C x" if "A x" "B x" for x |
|
804 |
||
805 |
Rare INCOMPATIBILITY, the old behaviour may be recovered as follows: |
|
806 |
||
807 |
show "C x" when "A x" "B x" for x |
|
808 |
||
60459 | 809 |
* New command 'consider' states rules for generalized elimination and |
810 |
case splitting. This is like a toplevel statement "theorem obtains" used |
|
811 |
within a proof body; or like a multi-branch 'obtain' without activation |
|
812 |
of the local context elements yet. |
|
813 |
||
60455 | 814 |
* Proof method "cases" allows to specify the rule as first entry of |
815 |
chained facts. This is particularly useful with 'consider': |
|
816 |
||
817 |
consider (a) A | (b) B | (c) C <proof> |
|
818 |
then have something |
|
819 |

||

|
834 |
||

Facts that are introduced by invoking the case context are uniformly |

836 |
qualified by "a"; the same name is used for the cumulative fact. The old |
|
837 |
form "case (c xs) [attributes]" is no longer supported. Rare |
