revived Refute in Mutabelle

tuned;

more scalable zero_var_indexes, depending on canonical order within table;

more benchmarks;

try different alternatives in discharging extra assumptions when schematic theorems obtained from lambda-lifting can be instantiated in different ways

replace higher-order matching against schematic theorem with dedicated reconstruction method

merged

tuned signature -- avoid spurious Thm.mixed_attribute;

discontinued numbered structure indexes (legacy feature);

tuned proofs;

return outcome code, so that it can be picked up by Mutabelle

align columns in output and keep error log around

offline build of java_ext_dirs.jar, to avoid runtime dependency on javac/jar executables;

clarified attribute "mono_set": pure declaration, proper export in ML;

misc tuning;

made SML/NJ happy;

more millisecond cleanup

updated documentation

try "smt" as a fallback for ATPs if "metis" fails/times out

more detailed preplay output

more explicit representation of rule_attribute vs. declaration_attribute vs. mixed_attribute; misc tuning;

cascading timeouts in minimizer, part 2

tuning

use "Time.time" rather than milliseconds internally

tune: no need for option

cascading timeouts in minimizer

shortcut binary minimization algorithm

speed up binary minimizer in practice by preferring the first half of the used facts (which are likelier to be relevant) to the second half

renamed experimental systems

repaired quantification over type variables for non-TFF1/THF encodings

misc tuning and modernization; more antiquotations;

misc tuning and modernization; more antiquotations;

tuned;

some statespace benchmarks;

write changed .prv files only, to avoid writing into src file-space by default;

tuned document; tuned proofs;

more precise dependencies;

inlined antiquotations;

misc tuning and modernization;

optional timing, to avoid redundant allocation of mutable cells;

tuned;

misc tuning;

merged

more use of global operations (see 98ec8b51af9c)

more uniform instT_subst vs. inst_subst: compare variable names only;

tuned cterm_instantiate: avoid somewhat expensive Term.map_types and cterm_of;

misc tuning and modernization;

some performance tuning via Term_Subst/Same.operation; tuned;

pruned signature;

added Logic.varify_types_global/unvarify_types_global, which avoids somewhat expensive Term.map_types; tuned;

more conventional syntax const;

proper syntactic category for abstraction syntax, to avoid low-level exception for malformed "\<integral> x y. f \<partial>M", for example;

merged

prefer global Quotient_Info lookup to accomodate Quotient_Term, which is not quite localized yet (cf. 9fd6fce8a230);

document new experimental provers

added remote iProver(-Eq) for experimentation

merged

ex/Tree23.thy: automate proof of gfull_add

ex/Tree23.thy: simplify proof of bal_del0

ex/Tree23.thy: simplify proof of bal_add0

ex/Tree23.thy: simpler definition of ordered-ness predicate

ex/Tree23.thy: prove that deletion preserves balance

more liberal Parse.fixes, to avoid overlap of mixfix with is-pattern (notably in 'obtain' syntax);

more general Proof_Context.bind_propp, which allows outer parameters; obtain: some support for term bindings within the proof, depending on parameters;

tuned whitespace;

tuned signature;

tuned signature -- canonical argument order;

tuned -- Variable.declare_term is already part of Variable.auto_fixes;

ex/Tree23.thy: prove that insertion preserves tree balance and order

more IMP fragments

string -> vname

JMPF(LESS|GE) -> JMP(LESS|GE) because jumps are int now.

more IMP text fragments

moved latex generation for HOL-IMP out of distribution

renaming Quotient_Set and List_Quotient_Set to Quotient_Cset and List_Quotient_Cset to avoid name clash with existing Quotient_Set (again, cf. 66823a0066db)

merged

more robust, declarative and unsurprising computation of types in the quotient type definition

improve handling of bound type variables (esp. for TFF1)

improved TFF1 output

clarified signature

tuned

even more uniform Local_Theory.declaration for locales (cf. 57def0b39696, aa35859c8741);

removed obsolete argument (cf. aa35859c8741);

removed ad-hoc simp rules sin_cos_eq[symmetric], minus_sin_cos_eq[symmetric], cos_sin_eq[symmetric]

extend cancellation simproc patterns to cover terms like '- (2 * pi) < pi'

merged

remove unused function

also export DFG formats

always use DFG format to talk to SPASS -- since that's what we'll need to use anyway to benefit from sorts and other extensions

added DFG unsorted support (like in the old days)

gracefully do nothing if the SPASS input file is already in DFG format

added sorted DFG output for coming version of SPASS

specify proof output level 1 (i.e. no detailed, potentially huge E proofs) to LEO-II; requires version 1.2.9

check "sound" flag before doing something unsound...

uniform treatment of syntax declaration wrt. aux. context (NB: notation avoids duplicate mixfix internally);

tuned;

more accurate class constraints on cancellation simproc patterns

tuned;

tuned Named_Thms: proper binding;

refined Local_Theory.declaration {syntax = false, pervasive} semantics: update is applied to auxiliary context as well;

uniform Local_Theory.declaration with explicit params;

tuned signature -- refined terminology;

slightly more explicit/syntactic modelling of morphisms;

correct import path

allow to build Probability and MV-Analysis with one ROOT.ML
