first step in sharing more code between ATP and Metis translation

more precise authorship, reflecting my own ignorance and hg annotate

generate raw induction rule as instance of generic rule with careful treatment of currying

generic fixpoint induction (with explicit curry/uncurry predicates) and instance for option type

admissibility on option type

also manage induction rule; tuned data slot

improving overlord option and partial_term_of derivation; changing Narrowing_Engine to print partial terms

merged

Workaround for bug involving makeindex, hyperref and the | symbol

parameterize print_theorems over actual search function

added experimental yxml_find_theorems web service (but no client yet)

generic ScgiServer.simple_handler

moved html templates to a separate module, making their awkward signatures explicit

attempt to clarify code; removed "handle _" and dead code

(de)serialization for search query and result

explicit type for search queries

moved questionable goal modification out of filter_theorems

exported raw query parser; removed inconsistent clone

separate query parsing from actual search

fixed bug in appending special facts introduced in be0e66ccebfa -- if several special facts were added, they overwrote each other

document new explicit apply

made "explicit_apply" smarter -- no need to force explicit applications in minimizer on all constants, better do it more fine granularly

don't slice if there are too few facts

nicer failure message when one-line proof reconstruction fails

make SML/NJ happy

avoid monomorphic encoding with so many facts -- it makes the old monomorphizer explode on some examples

make all messages urgent in verbose mode

minimize automatically even if Metis failed, if the external prover was really fast

fixed syntax of min options

no more bonus for E -- with the soft timeout, this punishes everybody -- the bonus was designed for a hard timeout

better merging of similar outputs

update minimization documentation

imported patch sledge_doc_metis_as_prover

automatically minimize with Metis when this can be done within a few seconds

minimize with Metis if possible

support "metis" and "metisFT" as provers in the architecture, so they can be used for minimizing

Workaround for hyperref bug affecting index entries involving the | symbol

improving heuristics of type annotations in contravariant positions for the special case with instances of the class partial_term_of

automatic derivation of partial_term_of functions; renaming type and term to longer names narrowing_type and narrowing_term; hiding constant C; adding overlord option

merged multiple heads

Fix to exception THM 1 raised (line 212 of conv.ML), reported by Andreas Lochbihler

always check plain "metis" even if the ATP proof seems to require "metisFT" -- maybe the proof is needlessly complicated

normalize indices in chained facts to make sure that backtick facts (which often result in different names) are recognized + changed definition of urgent messages

function tutorial: do not omit termination proof, even when discussing other things

added re-implemented monomorphizer for types with better control for number of generated instances (strict as opposed to the SMT monomorphizer) and with fact annotations controlling in which round certain facts are considered for monomorphization

document new "try"

tuned comments

new timeout section (cf. Nitpick manual)

cleanup proof text generation code

more Sledgehammer documentation updates

minor update

try both "metis" and (on failure) "metisFT" in replay

show time taken for reconstruction

unbreak "max_potential" logic

more concise output

compile

use helpers and tweak Quickcheck's priority to it comes second (to give Solve Direct slightly more time before another prover runs)

repaired theory merging and defined/used helpers

make Sledgehammer a little bit less verbose in "try"

handle non-auto try cases gracefully in Try Methods
