delete commented-out dead code

merged

change some subsection headings to subsubsection

remove unnecessary lemma card_ge1

move connected_real_lemma to the one place it is used

merged

make sure that all facts are passed to ATP from minimizer

more reliable "sledgehammer\_tac" reconstruction, by avoiding "insert_tac"

specify timeout for "sledgehammer_tac"

tuning

Quotient Package: add mem_rsp, mem_prs, tune proofs.

merged

declare euclidean_simps [simp] at the point they are proved; avoid duplicate rule warnings;

merged

merged

avoid warnings

comment out dead code to avoid compiler warnings

legacy theorem names

remove duplicate lemma

fixed "hBOOL" of existential variables, and generate more helpers

don't select facts when using sledgehammer_tac for reconstruction

don't perform a triviality check if the goal is skipped anyway

optional reconstructor

misc tuning and simplification;

tuned pri: prefer purging of canceled execution;

tuned Document.node: maintain "touched" flag to indicate changes in entries etc.;

clarified Document.Node.clear -- retain header (cf. ML version);

clarified norm_header/header_edit -- disallow update of loaded theories;

misc tuning and simplification;

ignore irrelevant timings;

print state only for visible command, to avoid wasting resources for the larger part of the text;

early filtering of unchanged perspective;

more reliable update_perspective handler based on actual text visibility (e.g. on startup or when resizing without scrolling);

update_perspective without actual edits, bypassing the full state assignment protocol; edit_nodes/Perspective: do not touch_descendants here; propagate editor scroll events via update_perspective; misc tuning;

tuned;

handle potentially more approriate BufferUpdate.LOADED event;

special treatment of structure index 1 in Pure, including legacy warning;

compile

added "max_calls" option to get a fixed number of Sledgehammer calls per theory

beef up "sledgehammer_tac" reconstructor

clean up Sledgehammer tactic

fixed document;

tuned signature;

merged

always use TFF if possible

clearer separator in generated file names

exploit TFF format in Z3 used as ATP, and renamed it "z3_tptp"

updated known failures for Z3 3.0 TPTP

updated Z3 docs

avoid TFF format with older Vampire versions

update the Vampire related parts of the documentation

fixed TFF slicing

kindly ask Vampire to output axiom names

added formats to the slice and use TFF for remote Vampire

tuned specifications, syntax and proofs

tuned specifications and syntax

Quotient Package: some infrastructure for lifting inside sets

include all encodings in tests, now that the incompleteness of some encodings has been addressed

change Metis's default settings if type information axioms are generated

we must tag any type whose ground types intersect a nonmonotonic type

prefer the lighter, slightly unsound monotonicity-based encodings for Metis

made reconstruction of type tag equalities "\?x = \?x" reliable

tuning ATP problem output

revert guard logic -- make sure that typing information is generated for existentials

generate tag equations for existential variables

tuning, plus started implementing tag equation generation for existential variables

precisely distinguish between universal and existential quantifiers, instead of assuming the worst (universal), for monotonicity analysis

clearer terminology

renamed "heavy" to "uniform", based on discussion with Nick Smallbone

removed unused configuration option

added caching for (in)finiteness checks

remove needless typing information

cleaner handling of polymorphic monotonicity inference

started cleaning up polymorphic monotonicity-based encodings, based on discussions with Nick Smallbone

more precise warning

added option to control soundness of encodings more precisely, for evaluation purposes

make sound mode more sound (and clean up code)

reintroduced slightly unsound optimization taken out in 717880e98e6b, but only if "sound" is false

gracefully handle empty SPASS problems

pass sound option to Sledgehammer tactic

tuned signature -- contrast physical output primitives versus Output.raw_message;

tuned signature;

discontinued slightly odd Future/Lazy.get_finished, which do not really fit into the execution model of Future.cancel/join_tasks (canceled tasks need to be dequeued and terminated explicitly);

some support for toplevel printing wrt. editor perspective (still inactive);

propagate editor perspective through document model;

some support for editor perspective;

discontinued redundant Edit_Command_ID;

reduced warnings;

tuned message;

old-style numbered structure index is legacy feature (hardly ever used now);

added official Text.Range.Ordering; some support for text perspective;

tuned signature;

reverted some odd changes to HOL/Import (cf. 74c08021ab2e);

merged

modernized specifications

removed session HOL/Subst -- now subsumed my more modern HOL/ex/Unification.thy
