some specific message classification;

Syntax.read_asts error: report token ranges within message -- no side-effect here;

Isabelle_Process: status/report do not require serial numbers;

simplified some internal flags using Config.T instead of full-blown Proof_Data;

tuned signature of (Context_)Position.report variants;

update README

regenerate "metis.ML"

fix license

updated source files with Metis 2.3 (timestamp: 16 Sept. 2010)

move functions around

simplify Skolem handling; things are much easier now that Sledgehammer doesn't skolemize, only Metis

make "subst_translation" more robust w.r.t. type instantiations like {_1234 |-> 'a}

complete refactoring of Metis along the lines of Sledgehammer

got caught once again by SML's pattern maching (ctor vs. var)

added new "Metis_Reconstruct" module, temporarily empty

rename "Metis_Clauses" to "Metis_Translate" for consistency with "Sledgehammer_Translate"

move SPASS's Flotter hack to "Sledgehammer_Reconstruct"

skip some "important" messages

refactoring: move ATP proof and error extraction code to "ATP_Proof" module

merged

added lemmas

merged

proper closures for static evaluation; no need for FIXMEs any longer

refined static_eval_conv_simple; tuned comments

closures preserve static serializer context for static evaluation; tuned

closures separate serializer initialization from serializer invocation as far as appropriate

add full support for datatypes to the SMT interface (only used by Z3 in oracle mode so far); added store to keep track of datatype selector functions

made sml/nj happy

merged

added code_stmts antiquotation from doc-src/more_antiquote.ML

added output_typewriter from doc-src/more_antiquote.ML

moved material intro distribution proper

merged

merged

separation of static and dynamic thy context

adjusted setup

dynamic and static value computation; built-in evaluation of propositions

Exn.map_result

adjusted to changes in Code_Runtime

merged

merged

improving replacing higher order arguments to work with tuples

adding another context free grammar example for the predicate compiler

adding values to show and ensure that values works with complex terms and restores numerals on natural numbers

adding restoring of numerals for natural numbers for values command

values command for prolog supports complex terms and not just variables

adapting examples

registering code_prolog as component; using environment variable; adding settings file for prolog code generation

adding mode inference to prolog compilation; separate between (ad-hoc) code modifications and system_configuration; adapting quickcheck

merged

tidied a few proofs

merged

avoid code duplication

tuning

merge constructors

factor out the inverse of "nice_atp_problem"

use the same TSTP/Vampire/SPASS parser for one-liners as for Isar proofs

factored out TSTP/SPASS/Vampire proof parsing; from "Sledgehammer_Reconstructo" to a new module "ATP_Proof"

prevent exception when calling "Mirabelle.can_apply" on empty proof sequence; the Judgement Day logs sometimes had entries of the form at 970:26 (apply): ------------------ ------------------ ; these were apparently caused by this Mirabelle bug

supply the Metis parameter defaults as argument, instead of patching the Metis sources; these values were found by Larry in 2007 and using anything else risks losing proofs

regenerated "metis.ML"

streamlined "make_metis"

put Isabelle-specifics in a "PortableIsabelle" file maintained by us; as recommended by Joe Hurd

handy little script

reintroduce missing "critical"s by hand

MIT license -> BSD License

copied the unmodified official Metis 2.3 (15 Sept. 2010) sources into Isabelle

tuned;

allow embedded reports in regular prover messages, to avoid side-effects for errors for example;

simplified/clarified (Context_)Position.markup/reported_text;

eliminated markup "location" in favour of more explicit "no_report", which is actually deleted from messages;

Isar "default" step needs to fail for solved problems, for clear distinction of '.' and '..' for example -- amending lapse introduced in 9de4d64eee3b (April 2004);

updated generated file;

tuned whitespace

reverse order of datatype declarations so that declarations only depend on already declared datatypes

merged

make "metis.ML" building process slightly more robust by eliminating the need for "FILES"; instead, query the original "Makefile"

dropped obsolete src/Tools/random_word.ML -- superseded by src/Tools/Metis/src/Random.sml stemming from the Metis distribution;

merged

document Metis updating procedure

move "CRITICAL" to "PortableXxx", where it belongs and used to be; now that it is no longer used in "Random.sml"

regenerated "metis.ML"

update comment

make "Unprotected concurrency introduces some true randomness." be true; this code is called often and doesn't need to be considered critical. I added CRITICAL by mistake.

fix parsing of higher-order formulas; this code was never exercised before because the current ATPs perform clausification, but someday ATPs might support FOF natively

merged

load code_runtime immediately again

proper interface for code_reflect

introduced "holds" as synthetic datatype constructor for "prop"; moved Pure code generator setup to Code_Generator.thy

merged

"Metis." -> "Metis_" to reflect change in "metis.ML"

no need for "metis_env.ML" anymore; it was a neat solution but it didn't work anymore once I removed the "structure Metis"

regenerate "metis.ML", this time without manual hacks

remove needless file for us

got rid of three crude regexps from "make_metis"

more Isabelle-specific changes

tuning

rename

use "Metis_" prefix rather than "Metis" structure; the prefix can then be used not only for structures but also signatures and functors. A few other changes were made to the script, to eliminate the need for "metis_env.ML".

no need for TPTP

put "foldl" and "foldr" in "Useful"; Isabelle hides those symbols from List, but by adding them to Useful we have them throughout Metis without "List." prefix

reintroduce the CRITICAL sections from change 3880d21d6013

apply Larry's hacks directly to the "src" files; these hacks modify the defaults of Metis heuristics and are necessary for backward compatibility

"FILES" is not (anymore?) part of the official Metis sources, so move it up

merged

Code_Runtime.value, corresponding to ML_Context.value; tuned

Code_Runtime.value, corresponding to ML_Context.value

more accurate dependencies

code_eval renamed to code_runtime

merged

static nbe conversion

ignore code cache optionally; corrected scope of term value in static_eval_conv

ignore code cache optionally

dropped redundant normal_form command

more explicit theory name

more accurate dependencies

merged

more clear separation of static compilation and dynamic evaluation
