* ML/Pure/General: improved join interface for tables;

consts: maintain thy version for efficient transfer; ins_sorts: Vartab.replace is slower than Vartab.update, but might avoid some copying of table structure;

tuned;

export exception SAME (for join); join: use internal modify, no option type (handle SAME/DUP instead); defined: simplified copy of lookup code, avoids allocation of option constructor; added replace, which does not change equal entries;

low-level tuning of merge: maintain identity of accesses; simplified TableFun.join;

share exception UNDEF with Table; simplified TableFun.join;

structure Datatab: private copy avoids potential conflict of table exceptions; simplified TableFun.join;

added eq_consts; reverted abbrevs: try all abstraction prefixes;

minor tuning of proofs, notably induct;

simplified TableFun.join;

\usepackage{amssymb};

* include generalised MVT in HyperReal (contributed by Benjamin Porter) * add non-denumerability of continuum in Real, includes closed intervals on real (contributed by Benjamin Porter, #22 in http://www.cs.ru.nl/~freek/100/)

* moved ThreeDivides from Isar_examples to better suited HOL/ex * moved 2 summation lemmas from ThreeDivides to SetInterval

divisibility by 3 theorem, contributed by Benjamin Porter, #85 in http://www.cs.ru.nl/~freek/100/

replaced mixfix_conflict by mixfix_content;

added map_theory; added rename_frees; removed custom_accesses; added qualified_force_prefix; tuned local syntax;

added abbreviations: activated by init, no expressions yet;

added restore; consts: provide abbreviations;

tuned mixfixes, mixfix_conflict;

removed custom_accesses; added suffixes_prefixes_split, qualified_force_prefix;

added variant_name;

removed custom_accesses; added qualified_force_prefix;

tuned;

added chop (sane version of splitAt); added prefixes, suffixes;

Changed some code due to changes in reduce_axiomsN.ML.

Added another filter strategy.

improved code generator devarification

statement: improved error msg;

* ML/Pure: generic Args/Attrib syntax everywhere;

moved fixedN to lexicon.ML; tuned;

added mfix_delims; tuned;

added mixfix_conflict;

added fixedN, constN;

tuned comment; moved local syntax to local_syntax.ML; common naming (for abbrevs and thms); transfer: merge consts; tuned pretty_term'; added polymorphic -- special case of generalize; added add_abbrevs(_i); read/cert: expand_consts;

tuned comment;

syntax: Context.generic;

Context.generic is canonical state of parsers; removed obsolete global/local parsers; tuned interfaces;

Local syntax depending on theory syntax.

decode: observe Syntax.constN;

removed obsolete add_typ/term_classes/tycons;

tuned extern_term, pretty_term';

removed set quick_and_dirty and ThmDeps.enable -- no effect here;

abbrevs: store in reverted orientation; tuned;

use proof_general.ML: setmp quick_and_dirty captures default value;

added Isar/local_syntax.ML;

tuned;

Args/Attrib syntax: Context.generic;

simplified polyml example;

tidying

blacklist tweaks

names for simprules

removed redundant lemmas

no longer need All_equiv lemmas

map_type_tvar/tfree: map_atyps;

tuned;

*** empty log message ***

made "dvd" on numbers executable by simp.

introduced gen_distinct in place of distinct

fixed the most silly bug conceivable in map_atyps

lambda: base name of Const;
