CCL/ccl.ML/po_refl_iff_T: deleted reference to make_iff_T CCL/ccl.ML/CCL_ss: now includes po_refl RS P_iff_T

Improved layout for inductive defs

adapted type definition to new syntax

fixed misfeature in Sign.extend: types of consts were read wrt. the new syntax;

changed "x" to "uu" for implicit name of the dependent type variable

update towards LNCS

deleted a comment

*** empty log message ***

improved explode_tr;

minor update because HOL-lemma changed

tactic/make_elim_preserve: recoded to avoid using lift_inst_rule. Instead instantiate changes the indices of V and W. tactic/cut_inst_tac: new

moved 'unlink ".tmp.ML"' away from 'use ".tmp.ML"' to try to fix a bug with SML

double_complement_Un: new

*** empty log message ***

improved eq_sg; cosmetical change in print_sg;

added eq_set;

correction to cut tactics

no longer removes *.z

now makes HOLCF

added strs, big_list, writeln;

added simple_string_of_typ, simple_pprint_typ; various internal changes;

added type 'syntax'; added syntax_consts (_K, _explode, _implode, ...);

minor internal changes;

syntax for type abbreviations;

(this is a preliminary release) type abbreviations;

added if_none, parents, commas, gen_duplicates, duplicates, assoc2; changed cat_lines: no final "\n";

replaced pprint_sg by Sign.pprint_sg; added Syntax.simple_pprint_typ;

replaced eq_sg by Sign.eq_sg;

removed eq_sg, pprint_sg, print_sg (now in sign.ML); removed cterm_fun, read_ctyp (now in thm.ML); print_theory: now shows all contents;

major cleanup; added eq_sig; added print_sg (full contents), pprint_sg (stamps only); added certify_typ, certify_term; changed read_typ: result now certified;

extend_theory: changed type of "abbrs" arg; added cterm_fun, read_ctyp (from drule.ML); ctyp_of, cterm_of, etc.: now use Sign.certify_...; assumption: now uses Envir.is_empty; bicompose_aux: fixed BUG (unifier with empty "asol" but non-empty "iTs" wasn't applied); fixed axioms_of;

made error message "file not found" more informative

case was renamed to sum_case

added is_empty: env -> bool, minidx: env -> int option;

added HOLCF

removed square and fact

HOLCF examples

Franz Regensburger's Higher-Order Logic of Computable Functions embedding LCF in HOL.

commented out sig constraint of functor (for debugging purposes);

changed SYNTAX_FILES;

contains remaining parts of xgram.ML and extension.ML; syn_ext replaces xgram and ext;

minor internal changes;

MAJOR INTERNAL CHANGE: extend and merge operations of syntax tables now much leaner (eliminated gramgraph, all data except tables of old parser are shared); simplified the internal interfaces for syntax extension; added translations for _explode, _implode (experimental);

MAJOR INTERNAL CHANGE: extend and merge operations of syntax tables now much leaner (eliminated gramgraph, all data except tables of old parser are shared); simplified the internal interfaces for syntax extension;

added some utils: commas, breaks, fbreaks, block, parents, list, str_list;

cosmetic changes;

minor cleanup; added extend, merge; added {lookup,make,dest}_multi;

major cleanup and reorganisation; added generic_extend, generic_merge; added various minor functions;

Updated refs to old Sign functions

Many other files modified as follows: s|Sign.cterm|cterm|g s|Sign.ctyp|ctyp|g s|Sign.rep_cterm|rep_cterm|g s|Sign.rep_ctyp|rep_ctyp|g s|Sign.pprint_cterm|pprint_cterm|g s|Sign.pprint_ctyp|pprint_ctyp|g s|Sign.string_of_cterm|string_of_cterm|g s|Sign.string_of_ctyp|string_of_ctyp|g s|Sign.term_of|term_of|g s|Sign.typ_of|typ_of|g s|Sign.read_cterm|read_cterm|g s|Sign.read_insts|read_insts|g s|Sign.cfun|cterm_fun|g

Pure: MAJOR CHANGE. Moved ML types ctyp and cterm and their associated functions from sign.ML to thm.ML or drule.ML. This allows the "prop" field of a theorem to be regarded as a cterm -- avoids expensive calls to cterm_of.

some optimizations of Larry's
