alternative shortcut for English keyboard;

merged

eliminated redundant is_ident -- more official is_identifier;

updated to jdk-7u9;

report proper pid *after* fork;

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

removed duplicate decleration

made use of sledgehammer_util

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;

refined outer syntax 'help' command;

tuned signature;

always reset active areas;

no special treatment of control_reset, in accordance to other control styles;

tuned signature;

tuned signature;

tuned signature;

tuned signature; uniform view.fontsize fallback;

renamed main plugin object to PIDE;

tuned signature -- avoid intrusion of module Path in generic PIDE concepts;

explicit module UTF8;

tuned file name;

Isabelle-specific implementation of quasi-abstract markup elements -- back to module arrangement before d83797ef0d2d;

prefer strict error;

quasi-abstract module Rendering, with Isabelle-specific implementation;

added convenience actions isabelle.increase-font-size and isabelle.decrease-font-size;

eval PDF_VIEWER/DVI_VIEWER command line, which allows additional quotes for program name, for example;

retain hidden_color (i.e. transparent white) instead of replacing it by semantic text color, to make control symbols more hidden and avoid "dirty" lines with some fonts;

prefer buffer_edit combinator over Java-style boilerplate;

more robust font for control symbols, to ensure these obscure codepoints are properly rendered;

tuned symbol groups;

tuned -- Symbol.groups already sorted;

more robust default font -- user might have switched jEdit TextArea to another font that lacks glyphs;

added option jedit_symbols_search_limit;

avoid empty tooltip;

tuned symbol groups;

special handling of control symbols in Symbols dockable; less obscure Scala names;

recovered some tooltip wrapping from e2762f962042, with multi-line support via HTML.encode;
