tweak SPASS default a tiny bit, so that a more interesting heuristic is chosen when "slicing=false" (for experiments)

some notes on the Isabelle component repository at TUM;

use filterlim in Lim and SEQ; tuned proofs

conversion rules for at, at_left and at_right; applied to l'Hopital's rules.

weakened assumptions for lhopital_right_0

tuned proof

add L'Hôpital's rule

add filterlim rules for exp and ln to infinity

add filterlim rules for inverse and at_infinity

add filterlim rules for diverging multiplication and addition; move at_infinity to the HOL image

add filterlim rules for unary minus and inverse

rename filter_lim to filterlim to be consistent with filtermap

add check to Cooper's algorithm that left-hand of dvd is a numeral

robust writing of MaSh state -- better drop learning data than cause other problems in Sledgehammer

avoid odd warnings due to failure of systray icon;

synchronized read access to cache file -- avoid potential conflict with ongoing write (which is non-atomic); clarified signature -- cache init is unsynchronized and hopefully used at most once per file;

tuned;

recovered error to finish proof (e.g. bad obtain export) from 223f18cfbb32; tuned message;

semi-automated Cygwin setup;

misc tuning;

updated to sumatra_pdf-2.1.1;

tuned order of functions

proper quoting of paths in MaSh

updated to jedit_build-20121201 (based on jedit-5.0.0);

moved isabelle shortcuts to main jEdit.props, in order to have them migrated to the "imported" keymap;

leave ALTERNATIVE_DISPATCHER mostly enabled on Mac OS X, to get events for COMMAND/Meta combinations, which seem to produce only KEY_PRESSED in Java 7, not KEY_TYPED as in Java 6;

updated to jedit-5.0.0;

more generic directory name to facilitate tracking changes of diffs;

merged

tuned

added 'print_inductives' command;

print formal entities with markup;

tuned labels;

renamed dockable "Prover Session" to "Theories"; more uniform Library.lowercase/uppercase;

tuned import;

alternative shortcut for English keyboard;

merged

eliminated redundant is_ident -- more official is_identifier;

updated to jdk-7u9;

updated to exec_process-1.0.3;

report proper pid *after* fork;

prefer Symbol.decode_strict in batch mode, to avoid files with spurious Unicode symbols that clash with Isabelle symbol interpretation;

more defensive retry via fork;

merged

parametrized correspondence relation: more robust procedure - don't ignore sorts; tuned

simplified use of fold/map; tuned;

tuned;

prefer 32 bit platform for ISABELLE_FULL_TEST, to make memory problems more explicit instead of disk thrashing (notably in HOL-Quickcheck_Benchmark);

merged

make SML/NJ happy (give names for all fields in a record)

more robust syntax that survives collapse of \<^isub> and \<^sub>;

further update and clarification of the all-important README_REPOSITORY;

more uniform ML statistics;

merged

improved readability

tweaked calculation of sledgehammer messages

adapted sledgehammer warnings

fixed case split preplaying

fixed preplaying of case splits; incorperated new name of structure: Isabelle_Markup -> Markup

preplay case splits

added warning when shrinking proof without preplaying

deal with the case that metis does not time out, but fails instead

reapplied changes to make SML/NJ happy

renaming, minor tweaks, added signature

added signature

moved thms_of_name to Sledgehammer_Util and removed copies, updated references

removed duplicate decleration

made use of sledgehammer_util

renamed sledgehammer_isar_reconstruct to sledgehammer_proof

added comments to new source files

fixed problem with fact names

remove hack and generalize code slightly

simplified isar_qualifiers and qs merging

put shrink in own structure

put annotate in own structure

support assumptions as facts for preplaying

some minor improvements in shrink_proof

some support for ML runtime statistics;

prefer tight Markup.print_int/parse_int for property values;

clarified new identifier syntax: exclude \<^isup>, include subscripted prime (to allow imitating full identifier here);

eliminated slightly odd identifiers;

tuned syntax, potentially more robust;

smarter list layout;

repaired text following 491c5c81c2e8;

merged

introduce filter_lim as a generatlization of tendsto

merged

based countable topological basis on Countable_Set

qualified interpretation of sigma_algebra, to avoid name clashes

eliminated finite_set_sequence with countable set

support for sub-structured identifier syntax (inactive);

eliminated some improper identifiers;

add upper bounds for factorial and binomial; add equation for binomial using nat-division (both from AFP/Girth_Chromatic)

tuned signature; tuned;

more uniform Symbol.is_ascii_identifier in ML/Scala;

tuned;

clarified Symbol.scan_ascii_id; ATP: follow change from Symbol.scan_id to Symbol.scan_ascii_id, assuming that this was meant here, not fully symbolic Isabelle identifiers;

tuned;

convenience operations for table as set;

removed remains of Oheimb's double-space (cf. 0a5af667dc75);

tuned;

merged

updated two components

simplify code slightly

avoid non-ASCII sign

generate a parameterized correspondence relation

quot_thm_crel

add option_fold

add binomial_ge_n_over_k_pow_k

removed tool that was never finished

added file headers

updated MaSh doc

moved MaSh's Python code into Isabelle

updated NEWS etc.

distinguish declated tfrees from other tfrees -- only the later can be optimized away

clarified status of Legacy_XML_Syntax, despite lack of Proofterm_XML;

reset active areas on content update;

more general sendback properties; support for padding of line boundary, e.g. for ad-hoc insertion of commands via 'help';

tuned command descriptions;
