proper error handling for SMT solvers in Sledgehammer

NEWS

merge

integrated "smt" proof method with Sledgehammer

fixed confusion introduced in 008dc2d2c395

merged

reverted e7a80c6752c9 -- there's not much point in putting a diagnosis tool (as opposed to a proof method) in Plain, but more importantly Sledgehammer must be in Main to use SMT solvers

merged

tuned

merged

use partial_function instead of MREC combinator; curried rev'

added Heap monad instance of partial_function package

added Spec_Rule declaration to partial_function

basic documentation for command partial_function

remove outdated "(otherwise)" syntax from manual

declare recursive equation as ".simps", in accordance with other packages

merged

dropped accidental doubled computation

optionally force the remote version of an SMT solver to be executed

tuned

added a mode to only filter assumptions used in a Z3 proof (in which no proof reconstruction is performed)

changed SMT configuration options; updated SMT certificates

joined setup of SMT solvers in one place; turned Z3-specific options into SMT options (renamed configuration options from z3_* to smt_*); more detailed SMT exception; improved SMT filter interface

keep track of theorems initially given to SMT (even if they are rewritten); provide interface to filter theorems necessary for SMT proofs

merged

merge

clearer error messages

renaming

back again to non-Apple font rendering (cf. 4977324373f2);

dock isabelle-session at bottom (again, cf. 37bdc2220cf8) to ensure that controls are fully visible;

disable broken popups for now;

tuned;

do not handle arbitrary exceptions;

merged

Code_Runtime.trace

proper markup of uninterpreted ML text as @{ML_text}, not @{verbatim};

merged

improved English

whitespace tuning

no need to encode theorem number twice in skolem names

tuning

make SML/NJ happy

relaxing the filtering condition for getting specifications from Spec_Rules

adding new predicate compiler files to the IsaMakefile

using mode_eq instead of op = for lookup in the predicate compiler

renaming split_modeT' to split_modeT

options as first argument to check functions

changing test parameters in examples to get to a result within the global timelimit

adding a global fixed timeout to quickcheck

adding a global time limit to the values command

explicit message_output thread, with flushing after timeout, ensure atomic user-operations without the danger of IO Interrupt; eliminated auto_flush threads -- use plain line buffering for stdout/stderr; tuned;

more explicit indication of Output.Private_Hooks (still public to accomodate clones of Proof General for now);

renamed Output.priority to Output.urgent_message to emphasize its special role more clearly;

explicitly qualify type Output.output, which is a slightly odd internal feature;

export main ML entry by default; observe elisp format for preferences; clarified command setup;

observe Isabelle/ML coding standards;

merged

significantly improved Isabelle/Isar implementation manual;

misc tuning;

removed some remains of Output.debug (follow-up to fce2202892c4);

recovered some odd two-dimensional layout;

merged

dropped (almost) redundant distinct.induct rule; distinct_simps again named distinct.simps

moved sledgehammer to Plain; tuned dependencies
