valid_facts: more elementary version using Facts.fold_static;

Facts.dest_static;

Auxiliary permutation functions are no longer declared using add_consts_i, because add_primrec_overloaded can do this as well.

removed unused TLA/Memory/MIParameters.thy;

removed obsolete valid_thms; removed obsolete premsN binding; PureThy.get_fact: pass dynamic context;

removed obsolete premsN;

PureThy.get_fact: pass dynamic context;

tuned;

removed obsolete get_fact_silent; PureThy.get_fact: pass dynamic context; tuned;

tuned proofs;

Added entry for unused_thms command.

Adapted to new primrec package.

Added add_primrec_global and add_primrec_overloaded functions (thanks to Markus).

educated guess for infix syntax

removed test artefacts

proof endings: no Toplevel.print!

all_valid_thms: use new facts tables;

Theory.subthy;

Facts.intern, Facts.extern_table;

IsarCmd.hide_names;

added hide_names command (formerly Sign.hide_names), support fact name space;

Facts.dest_table, PureThy.facts_of;

simplified hide_XXX interfaces;

removed obsolete SIGN_THEORY -- no name aliases in structure Theory; removed obsolete BASIC_THEORY;

removed obsolete SIGN_THEORY -- no name aliases in structure Theory; simplified hide_XXX interfaces; moved hide_names to isar_cmd.ML;

added intern_fact, check_fact, hide_fact; renamed all_facts_of to facts_of; removed hide_thms; Sign.hide_const;

Theory.eq_thy;

renamed dest to dest_table, and extern to extern table; added name space intern/extern;

PureThy.hide_fact;

Facts.dest_table;

Sign.hide_const;

added hide fact;

tuned;

removed eval_antiquotes_fn; eval: CRITICAL for now;

merge: canonical order;

Library.is_equal;

moved forall_elim_var(s) to more_thm.ML; get_thm(s) and hide_thms: use new table;

disallow duplicate entries (weak version for merge); added hide;

Thm.forall_elim_var(s);

proper dynamic facts for eqvts, freshs, bijs; removed obsolete print_data -- facts are accesivle via regular names; misc tuning/simplification;

overloading perm: use big_name; avoid rebinding of perm_closed -- leftover debug code;

* Name space merge now observes canonical order; * Authentic naming of facts;

removed redundant hd_append variant;

removed duplicate lemmas;

avoid duplicate fact bindings;

overloading of perm: adhoc name prevents duplicate fact names;

Changed naming scheme for theorems generated by interpretations.

proper context for induct_scheme method

Isar.toplevel_loop: separate init/welcome flag;

Sorts.class_error: produce message only (formerly msg_class_error);

tsig: removed unnecessary universal witness; Sorts.class_error: produce message only (formerly msg_class_error);

simplified handling of sorts, removed unnecessary universal witness; Envir.insert_sorts;

removed unused minimal_classes; class_error: produce message only (formerly msg_class_error); tuned;

added insert_sorts (from thm.ML);

tsig: removed unnecessary universal witness;

tuned;

removed unnecessary Goal.close_result;

replaced Drule.close_derivation/Goal.close_result by Thm.close_derivation (removed obsolete compression); pred_def: tag internal;

advance: do not count utf8 trailer bytes (which happen to be undefined or punctuation in iso-latin);

added is_utf8_trailer;
