avoid prove_plain, export_plain, simplified after_qed; witness = term * thm, i.e. the original proposition with a protected fact (this achieves reliable discharge and allows facts to be slightly more general/normalized); internal assume/prove/conclude/satisfy_protected handle witness pairs accordingly; ObjectLogic.ensure_propT;

(codegen)

generate pattern combinators for new datatypes

reimplemented Case syntax using print/parse translations; moved as-patterns to separate section

add case syntax for type one

remove syntax for as-patterns

Added strong induction theorem (currently only axiomatized!).

Initial commit.

Initial commit of the theory "Weakening".

added thms perm, distinct and fresh to the simplifier. One would liket to add also inject, but this causes problems with "congruences" like Lam [a].t1 = Lam [b].t2 P (Lam [a].t1) ----------------------- P (Lam [b].t2) because the equation "Lam [a].t1 = Lam [b].t2" would simplify to "[a].t1 = [b].t2" and then the goal is not true just by simplification.

added proper fillin_mixfix

added fillin_mixfix, replace_quote

New function store_thmss_atts.

used the function Library.product for the cprod from Stefan

fixed bug with nominal induct - the bug occured in rule inductions when the goal did not use all variables from the relation over which the induction was done

added fillin_mixfix' needed by serializer

add case syntax stuff

use consts for infix syntax

add proof of Bekic's theorem: fix_cprod

simplify definitions

put iterate and fix in separate sections; added Letrec

renamed and added ch2ch, cont2cont, mono2mono theorems ending in _fun, _lambda, _LAM

add line breaks to Rep_CFun syntax

moved adm_chfindom from Fix.thy to Cfun.thy; moved admw-related stuff to its own section

moved adm_chfindom from Fix.thy to Cfun.thy

cleaned up

add print translation: Abs_CFun f => LAM x. f x

Changed the way additional lemmas are passed to ATP methods for proof of a goal: now only list them after the methods' names. Also removed some functions that are not used any more.

improve support for mutual recursion: now generates correct copy constant and induction theorem for mutually-recursive types; initial support for indirect recursion

reimplement copy_def to use data constructor constants

cleaned up; renamed library function mk_cRep_CFun to list_ccomb; replaced rep_TFree with dest_TFree; added functions spair, mk_stuple

generate lambda pattern syntax for new data constructors

changed order of arguments for constant behind If-then-else-fi syntax; added LAM patterns for TT, FF

add constant one_when; LAM pattern for ONE

add translation for wildcard pattern

change syntax for LAM to use expressions as patterns; define LAM pattern syntax for cpair, spair, sinl, sinr, up

make cpair_less, cpair_defined_iff into iff rules; add lemma csplit1

cleaned up; ch2ch_Rep_CFun is a simp rule

changed iterate to a continuous type

reorganized; removed intermediate constant Ifix; changed iterate to a continuous type; added theorem fix_least_less

removed ex/loeckx.ML

removed proof about Ifix, which no longer exists

cleaned up; chain_const and thelub_const are simp rules

cleaned up; removed adm_tricks in favor of compactness theorems

fix spelling

Moved atom stuff to new file nominal_atoms.ML

- completed the list of thms for supp_atm - cleaned up the way how thms are collected under single names

Added code for proving that new datatype has finite support.

removed unused modify_typargs, map_typargs, fold_typargs;

added Isar.state/exn;

Isar.loop;

moved consts declarations to consts.ML;

Consts.dest;

Polymorphic constants.

added consts.ML;

fromConst: use Sign.const_typargs for efficient representation of type instances of constant declarations;

dist_eqI: the_context();

Sign.const_monomorphic;

Logic.nth_prem;

added the collection of lemmas "supp_at"

some minor tweaks in some proofs (nothing extraordinary)

tunings of some comments (nothing serious)

nth_*, fold_index refined

fold_index replacing foldln

A few new lemmas

tuned my last commit

simplified the abs_supp_approx proof and tuned some comments in nominal_permeq.ML

Changed Simplifier.simp_modifiers to Simplifier.simp_modifiers'. This means the syntax of the tactics supports_simp and perm_simp are exactly like simp, namely (supports_simp add: .... del: ...) where the add's and del's are optional.

1) have adjusted the swapping of the result type in add_datatype_i 2) have replaced map_nth_elem by Library.nth_map (there seems to be a clash with an existing nth_map somewhere - therefore the "Library")
