merged

formerly unnamed infix equality now named HOL.eq

code checking: compiler invocation happens in same directory as generated file -- avoid problem with different path representations on cygwin

Quotient Package: dont unfold mem_def, use rsp and prs instead

Quotient Package: added respectfulness and preservation lemmas for mem.

quotient package: added a list of pre-simplification rules for Ball, Bex and mem

quotient package: lemmas to be lifted and descended can be pre-simplified

merged

renamed class/constant eq to equal; tuned some instantiations

improved deresolving of implicits

Document_View.text_area_extension: do not insist in crashing if (weak) assertion is violated;

Isabelle/jEdit property for global tooltip dismiss delay;

External_Hyperlink: proper error dialog;

Document_Mode.Line_Context: proper semantic equality/hash code avoids memory leak due to interning in org.gjt.sp.jedit.syntax.TokenMarker;

JEDIT_JAVA_OPTIONS: actors.enableForkJoin=false is supposed to enable ResizableThreadPoolScheduler, to avoid starvation of excessive amounts of future tasks etc.;

session_actor: ignore spurious TIMEOUT (again) -- probably stemming from earlier use of receiveWithin;

session_actor: await state assigment of previous change before signalling current change, and avoid crash in overrun situations;

use Future.get_finished where this is the intended meaning -- prefer immediate crash over deadlock due to promises that are never fulfilled; clarified session signalling;

Swing_Thread.now: volatile result to make double-sure;

Document_Model.token_marker: misc tuning and simplification;

added Document.Snapshot.select_markup, which includes command iteration, range conversion etc.; Markup_Tree.select: plain Iterator; misc tuning and simplification;

XML.Cache: intern property keys once and for all (again);

more careful locking of jEdit buffer;

avoid application crash due to wrong requirement -- result is joined, but change not necessarily finished due to extra map;

include Document.History in Document.State -- just one universal session state maintained by main actor; Session.command_change_buffer: thread actor ensures asynchronous dispatch; misc tuning;

volatile variables (in Scala);

non-critical output primitives -- depending on thread-safe TextIO, while races wrt. flushing should not matter;

modernized specifications;

discontinued separate Pure-ProofGeneral keywords session -- protocol commands are already defined in Pure;

discontinued broken no_warnings_CRITICAL -- global output channels must not be changed after startup initialization;

eliminated broken Output.no_warnings_CRITICAL -- context visibility does the job; modernized attribute setup;

more careful treatment of context visibility flag wrt. spurious warnings; misc tuning;

eliminated obsolete Output.no_warnings, where no warnings were produced anyway;

eliminated broken Output.no_warnings_CRITICAL -- context visibility does the job;

more careful treatment of context visibility flag wrt. spurious warnings;

merged

turn off experimental feature per default + avoid exception on "theory constant"

extended relevance filter with first-order term matching

drop chained facts

rename and simplify

cosmetics

renaming + treat "TFree" better in "pattern_for_type"

fix threshold computation + remove "op =" from relevant constants

avoid needless "that" fact

add nameless chained facts to the pool of things known to Sledgehammer

if the goal contains no constants or frees, fall back on chained facts, then on local facts, etc., instead of generating a trivial ATP problem

improve SPASS hack, when a clause comes from several facts

fix Vampire version numbers

lower penalty for Skolem constants

merged

official support for Scala

updated generated files

tuned whitespace

more xsymbols

re-added accidental omission

proper namespace administration for hierarchical modules

more antiquotations;

eliminated Unsynchronized.ref in favour of configuration option; proper naming of thy: theory vs. ctxt: Proof.context; recovered some Isabelle/ML indendation style;

more appropriate name for configuration option "meson_max_clauses" (cf. output of 'pront_configs');
