Turned Sem into an inductive definition.

Corrected handling of "for" parameters.

induct_true_def and induct_false_def are already contained in induct_rulify_fallback.

added lemma about irreflexivity of pointer inequality in Imperative_HOL

added function ffilter and some lemmas from Finite_Set to the FSet theory

merged

avoid if on rhs of default simp rules

avoid exception Empty on malformed goal

complete_lattice instance for net type

swap ordering on nets, so x <= y means 'x is finer than y'

fixrec no longer uses global simpset internally to prove equations

move setsum lemmas to Product_plus.thy

remove duplicate lemmas

add lemmas about convergent

Cleanup information theory

Moved Convex theory to library.

Generalize swap_inj_on; add simps for Times; add Ex_list_of_length, log_inj; Added missing locale edges for linordered semiring with 1.

proof terms for strip_shyps, based on the version by krauss/schropp with some notable differences: * present type variables are only compared wrt. first component (the atomic type), not the duplicated sort; * extra sorts are grounded towards fixed 'a, potentially with different sorts (the original version with Name.names could cause name clashes with other present variables, too, but this should not be a problem); * deriv_rule_unconditional ensures that proof terms are always maintained independently of the "proofs" flag -- this improves robustness and preserves basic PThm proofs required for extraction attributes, e.g. in theory HOL/Extraction;

simplified/unified fundamental operations on types/terms/proofterms -- prefer Same.operation over "option" variant;

renamed Proofterm.freezeT to Proofterm.legacy_freezeT (cf. 88756a5a92fc);

specification goal: eliminated redundant Thm.legacy_freezeT -- the goal is properly declared and should always produce fixed types in the result; specification result: replaced Thm.legacy_freezeT by Thm.unvarify_global -- the final result appears to be a closed term that is globally exported;

UNDISCH/DISJ_CASESL: eliminated slightly odd Thm.legacy_freezeT -- these rules appear to be applied to thms with fixed types only;

replaced Thm.legacy_freezeT by Thm.unvarify_global -- these facts stem from closed definitions, i.e. there are no term Vars;

renamed Thm.freezeT to Thm.legacy_freezeT -- it is based on Type.legacy_freeze;

minor tuning of Thm.strip_shyps -- no longer pervasive;

simplified primitive Thm.future: more direct theory check, do not hardwire strip_shyps here;

old NEWS on global operations;

ProofContext.init_global;

renamed ProofContext.init to ProofContext.init_global to emphasize that this is not the real thing;

do not generate code per default -- touches file of parent session

made sml/nj happy about Sledgehammer and Nitpick (cf. 6f11c9b1fb3e, 3c2438efe224)

Backed out changeset 6f11c9b1fb3e (breaks compilation of HOL image)

now if this doesn't make SML/NJ happy, nothing will

more stats;

renamed Variable.thm_context to Variable.global_thm_context to emphasize that this is not the real thing;

slightly more standard induct_simp_add/del attributes; provide explicit context for internal addsimps;

map_css: explicitly provide a temporary context, which might be required for mksimps, mkcongs etc.;

export Simplifier.with_context;

removed some old comments;

define linear algebra concepts using scaleR instead of (op *s); generalized many lemmas, though a few theorems that used to work on type int^'n are a bit less general

remove unused function vector_power, unused lemma one_plus_of_nat_neq_0

move class instantiations from Euclidean_Space.thy to Finite_Cartesian_Product.thy

minor improvements

identify axioms/conjectures more reliably in ATP proofs (an empty dependency list doesn't always indicate an axiom or conjecture!)

added "no_atp" for theorems that are automatically used or included by Sledgehammer when appropriate (about combinators and fequal)

in "overlord" mode: ignore problem prefix specified in the .thy file

uncomment code

redid some Sledgehammer/Metis proofs

fix more "undeclared symbol" errors related to SPASS's DFG format

be more discriminate: some one-line Isar proofs are silly

one-step Isar proofs are not always pointless

the SPASS output syntax is more general than I thought -- such a pity that there's no documentation

redo more Metis/Sledgehammer example

fixed definition of "bad frees" so that it actually works

don't remove last line of proof

handle previously unknown SPASS syntaxes in Sledgehammer's proof reconstruction

make SML/NJ happy, take 2

use readable names in "debug" mode for type vars + don't pipe facts using "using" but rather give them directly to metis (works better with type variables)

expand combinators in Isar proofs constructed by Sledgehammer; this requires shuffling around a couple of functions previously defined in Refute

more neg_clausify proofs that get replaced by direct proofs

redo some of the metis proofs

back to Vampire 9 -- Vampire 11 sometimes outputs really weird proofs

improve unskolemization

make sure short theorem names are preferred to composite ones in Sledgehammer; this code used to work at some point

properly extract SPASS proof

try out Vampire 11 and parse its output correctly; will revert to Vampire 9 if 11 doesn't perform as well

return updated info record after termination proof

proper context for rule_by_tactic;

conditional warnings: explicitly observe context visibility flag, not just accidental presence of a context; map_ss: explicitly provide a temporary context, which might be required for mksimps, mkcongs etc.;

hgweb style: show author in filelog; full description in annotate hover

proper context for mksimps etc. -- via simpset of the running Simplifier;

read_const: disallow internal names as usual in visible Isar text;

more explicit treatment of context, although not fully localized;

removed some Emacs junk;
