ML pretty printing of type string according to (quasi-abstract) YXML markup and symbols (including UTF8);

escape UTF8 symbols for the ML compiler;

explicit treatment of UTF8 character sequences as Isabelle symbols;

slight cleaning and simplification of the automatic wrapper for quotient definitions

merged

export of proper information in the ML-interface of the quotient package

treat Pretty.T as strictly abstract type;

slightly more standard data merge: Symtax.merge (K true) avoids equality on abstract type Pretty.T and gracefully accepts overriding, Symtab.join prefers first entry as usual;

avoid equality on abstract type Pretty.T;

notes on packaging;

misc tuning;

tuned auxiliary structures;

Net.encode_type;

more accurate dependencies;

fix syntax bug in the TPTP output, by ensuring that "hBOOL" is correctly used for n-ary predicates even if (n + k)-ary occurrences of the same predicate, but with a different type, occur in the same problem

renamed for easier grep

use Skolem inlining also in the nonpolymorphic case, as a step toward simplifying the source code

steal some of http://isabelle.in.tum.de/sledgehammer.html and add it to the docs

have "metis" method and "metis_tac" fall back on "metisFT" upon failure, following a suggestion by Larry

fix bug with "skolem_id" + sort facts for increased readability

if SPASS fails at finding a proof with the SOS option turned on, turn it off and try again

merged

this looks like the most appropriate place to do the beta-eta-contraction

killed legacy "neg_clausify" and "clausify"

merged

factor out TPTP format output into file of its own, to facilitate further changes

merged

turn on "natural form" filtering in the Mirabelle tests, to see how it performs

missing "Unsynchronized" + make exception take a unit

added code to optionally perform fact filtering on the original (non-CNF) formulas

more cosmetics

cosmetics + prevent consideration of inlined Skolem terms in relevance filter

canonical argument order

leverage new data structure for handling "add:" and "del:"

thread original theorem along with CNF theorem, as a step toward killing the Skolem cache

merge "generic_prover" and "generic_tptp_prover"

removed Sledgehammer's support for the DFG syntax; this removes 350 buggy lines from Sledgehammer. SPASS 3.5 and above support the TPTP syntax.

distinguish between "unknown" and "no Kodkodi installed" errors

reintroduce new Sledgehammer polymorphic handling code; this time I tested the proper version of Isabelle

make the Nitpick_Example theory processable even when Kodkodi is not installed; so that at least the "theory" aspects of it (as opposed to the diagnosis offered by Nitpick) are checked on everybody's machines

Make latex happy

Quotient package now uses Partial Equivalence instead place of equivalence

Replace 'list_rel' by 'list_all2'; they are equivalent.

Proper treatment of non-inherited mixins.

Introduce a type class for euclidean spaces, port most lemmas from real^'n to this type class.

reredisable new polymorphic code
