added Standard_System.slurp convenience; tuned;

added Simple_Thread.future convenience; tuned;

refined ML/Scala bash wrapper, based on more general lib/scripts/process;

tuned;

more robust Isabelle_System.rm_fifo: avoid external bash invocation, which might not work in JVM shutdown phase (due to Runtime.addShutdownHook);

tuned;

added Isabelle_Process.syslog; refined Isabelle_Process.process_manager: startup_output via syslog, explicit join of auxiliary threads; tuned;

updated keywords;

corrected long-overlooked slip: the Pure equality of a code equation is no part of the code equation itself

dynamic_eval_conv static_eval_conv: certification of previously unreliably reconstructed evaluated term

Pure equality is a regular cpde operation

remove needless exception

preprocess "Ex" before doing clausification in Metis; this is dual to "All" in b96941dddd04

expand_fun_eq -> fun_eq_iff

use buffers instead of string concatenation

renamed structure PureThy to Pure_Thy and moved most content to Global_Theory, to emphasize that this is global-only;

more antiquotations;

added XML.content_of convenience -- cover XML.body, which is the general situation;

preprocess "All" before doing clausification in Metis; helps the definitional clausifier produce fewer clauses

reorder proof methods and take out "best"; suggestions from Tobias

renaming variable name to decrease likelyhood of nameclash

code_pred_intro can be used to name facts for the code_pred command

replacing temporary hack by checking for environment settings of the component

removing unnessary options for code_pred

moving renaming_vars to post_processing; removing clone in values and quickcheck of code_prolog

removing clone in code_prolog and predicate_compile_quickcheck

adjusted

updated file duplicate

\\isatypewrite now part of isabelle latex style

made smlnj happy

properly parse Z3 error models, including datatypes, and represent function valuations as lambda terms; also normalize Z3 error models

do not treat natural numbers as a datatype (natural numbers are considered an abstract type with a coercion to integers)

generalized lemma insort_remove1 to insort_key_remove1

generalized lemmas multiset_of_insort, multiset_of_sort, properties_for_sort for *_key variants

less intermediate data structures

Isabelle_Process: more robust rendezvous, even without proper blocking on open (Cygwin);

simplified Isabelle_System.mk_fifo: inlined script, append PPID and PID uniformly;

refined Isabelle_Process startup: emit \002 before rendezvous on fifos, more robust treatment of startup failure with timeout, do not quit() after main loop; tuned;

back to default fold painter -- Circle looks slightly odd in conjunction with bracket matching;

message_actor: more robust treatment of EOF;

simplified Isabelle_Process message kinds; misc tuning and simplification;

recovered basic session stop/restart;

simplified fifo handling -- rm_fifo always succeeds without ever blocking; tuned;

raw_execute: let IOException pass-through unhindered (again);

mkfifo: some workaround to ensure reasonably unique id, even on Cygwin where $PPID might fall back on odd default;

Isabelle_System.mk_fifo: more robust enumeration of unique names, based on persisting JVM pid (parent of shell process);

slightly more robust Isabelle_Process startup -- NB: openening fifo streams synchronizes with other end, which may fail to reach that point;

tuned;

separate Isabelle.logic_selector;

non-editable text area;

basic setup for prover session panel;

ML_Syntax.print_char: more readable output of some well-known ASCII controls -- this is relevant for ML toplevel pp;

discontinued Output.debug, which belongs to early PGIP experiments (b6788dbd2ef9) and causes just too many problems (like spamming the message channel if it is used by more than one module);

Isabelle_Markup.overview_color: indicate error / warning messages;

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

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

separation of static and dynamic thy context

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
