skeleton for Simplifier trace by Lars Hupel;

generic trace operations for main steps of Simplifier;

tuned signature;

tuned whitespace;

added missing file (cf. 124432e77ecf);

tuned whitespace;

removed dead code -- ctxt is never visible (see also 658fcba35ed7);

simplified polyml-5.5.2 setup -- implicit upgrade of Thread.numProcessors;

tuned message;

be more explicit about pre- and postprocessor, particularly code_abbrev

removed obsolete codegen setup; Stream -> SCons; tuned

merged

tuned patterns;

support for polml-5.5.2; support Thread.numPhysicalProcessors of polyml-5.5.2 (according to SVN 1890); clarified max_threads: store plain value internally, reproduce result only on startup, and thus avoid potential system overhead;

reverse order in which lines are selected, to ensure that the number of dependencies is accurate

truncate proof once False is hit to avoid confusing the rest of the code (no idea why Z3 goes on)

removed inlined rewriting'' for one-branch case splits in Isar proofs, since these can yield huge unreadable formulas

Fib: Who needs the int version?

more work on Z3 Isar proofs

streamlined two proofs

merged

alternative hires icon;

NEWS

default code equations for make, fields, extend and truncate operations on records

browse directory hyperlink as well;

provide @{file_unchecked} in Isabelle/Pure;

tuned;

more antiquotations;

added document antiquotation @{url}, which produces formal markup for LaTeX and PIDE;

tuning -- moved ML files to subdirectory

adapted code for Z3 proof reconstruction

useful debugging info

disable generalization in MaSh until it is shown to help

bugfixes to Python MaSh related to alternative features

compile

generate problems with type classes

added warning to documentation, based on isabelle-users thread

more reasonable default weight

added multiple feature capability to MaSh

code equations for "local" (co)datatypes available after interpretation of locales with assumptions

more direct Isabelle_System.pdf_viewer; generic Isabelle_System.open, e.g. for URLs;

proper latex;

NEWS;

no keyboard control -- avoid confusion about meaning of selection;

directly react on click, assuming that document view operation is mostly idempotent;

generic $ISABELLE_OPEN;

updated to Sumatra PDF 2.4; prefer option -reuse-instance; PDF_VIEWER refers to program, not command-line;

clarified "isabelle display" and 'display_drafts': re-use file and program instance, open asynchronously via desktop environment;

tuned;

tuned proofs;

reverted 86e0b402994c, which was accidentally qfinish'ed and pushed

Better simprules and markup. Restored the natural number version of the binomial theorem

more uniform status -- accommodate spurious Exn.Interrupt from user code, allow ML_Compiler.exn_messages_id to crash; tuned signature;

strict EXEC_PROCESS: component can be expected to be present;

uniform use of transparent icons, as for main "apps";

more isabelle logos (from isabelle_transparent.ico);

recover 175b43e0b9ce from lost update in cc126144f662;

merged

relocate NEWS to post-release version (cf. 7a14f831d02d);

merged, resolving obvious conflicts in NEWS and src/Pure/System/isabelle_process.ML;

removed obsolete RC tags;

merged;

Added tag Isabelle2013-2 for changeset 4dd08fe126ba

remove junk;

recover main entry point from d9c88171b393 -- occasionally useful with plain "java -jar jedit.jar";

tuned;

tuned;

Added tag Isabelle2013-2-RC3 for changeset aeb21314d078

prefer transparent application icon (like Mac OS X);

specific application name for official bundle (as for Mac OS X);

prefer isabelle application icon;

more isabelle logos (from isabelle.ico);

prefer 32x32 icon like jedit (image from isabelle.ico);

updated isabelle.ico for the record (see also 84177f8372f9);

updated icon of Isabelle.exe, using http://convertico.org/image_to_icon_converter on lib/logo/isabelle.gif (approx. 256x256 pixels according to Windows 7 format);

further encouragement to read jEdit documentation;

clarified view.title;

NEWS;

non-focusable button, to avoid second interpretation of SPACE in C+e SPACE (isabelle.set-node-required);

more thorough read_pid with extra delay, to give external process a chance to write pid file before attempting to terminate it -- especially relevant for PIDE document processing, where interrupts can happen in the range of milliseconds;

Added tag Isabelle2013-2-RC2 for changeset 99b9249b3e05

more official task context via Task_Queue.enroll, which is required to participate in group cancellation (e.g. to terminate command exec); tuned signature;

NEWS;

more defensive order of Markup.failed vs. Markup.finished -- more informative status in Isabelle/Scala, although it is not rendered in Isabelle/jEdit;

more robust status reports: avoid loosing information about physical events (see also 28d207ba9340, 2bc5924b117f, 9edfd36a0355) -- NB: TTY and Proof General ignore Output.status and Output.report; more defensive order of Markup.failed vs. Markup.finished, to allow breakdown of ML execution context (see also d7a1973b063c);

more robust and portable invocation of kill as bash builtin, instead of external executable -- NB: /bin/kill on Mac OS X Mountain Lion chokes on Linux workaround from 3610ae73cfdb;

Added tag Isabelle2013-2-RC1 for changeset 57aefb80b639

more on GTK;

reintroduced e2d08b9c9047, lost in 54e290da6da8 + e13b0c88c798 (clone of f6ffe53387ef);

NEWS;

back to Status.FINISHED and immediate remove_overlay (reverting 6e69f9ca8f1c), which is important to avoid restart of print function after edits + re-assignment of located command; resolve sendback wrt. static command id, to allow active area even after exec_id is removed (cf. prune_delay);

updated to Isabelle2013-2;

compile on Windows (clone of d04576557400);

register actual group of nested worker context -- relevant for insulated cancellation of exec_ids (see also 78693e46a237, e0169f13bd37); tuned signature;

updated mirror script for Cambridge

proper code generation for discriminators/selectors

reverted 141cb34744de and e78e7df36690 -- better provide nicer "eta-expanded" definitions for discriminators and selectors, since users might want to unfold them

experiment

make sure acyclicity axiom gets generated in the case where the problem involves mutually recursive datatypes

news

restrict admissibility to non-empty chains to allow more syntax-directed proof rules

merge

generate "code" theorems for incomplete definitions

updated keywords

added 'no_code' option

killed obsolete artifact

revert making 'map_cong' a 'cong' -- it breaks too many proofs in the AFP

avoid user-level 'Specification.definition' for low-level definitions

repaired inconsistency introduced in transiting to 'Local_Theory.define'

docs for forgotten BNF theorems

tuning

added 'cong' attribute to 'map_cong'

avoid user-level 'Specification.definition' for internal constructions (to avoid e.g. automatic code generation behavior)

don't try to register code equations in a locale with assumptions

minor doc update

generalized datatype code generation code so that it works with old-style and new-style (co)datatypes (as long as they are not local)

simpler code

more work towards "exhaustive"

Backed out changeset: a8ad7f6dd217---bypassing Main breaks theories that use \<inf> or \<sup>

set_comprehension_pointfree simproc causes to many surprises if enabled by default
