support for nested text cartouches; clarified Symbol.is_symbolic: exclude \<open> and \<close>;

back to conditional tracing instead of noisy warning (see also 00e849f5b397): these incidents happen occasionally;

tuned;

prefer user-space tool within Pure.thy;

clarified @{rail} syntax: prefer explicit \<newline> symbol;

clarified Simplifier diagnostics -- simplified ML; unconditional warning for structural mistakes (NB: context of running Simplifier is not visible, and cond_warning ineffective);

folded 'Wellfounded_More_FP' into 'Wellfounded'

folded 'Order_Relation_More_FP' into 'Order_Relation'

support declaration of nonemptiness witnesses in bnf_decl

hide short const name

get rid of 'rel' locale, to facilitate inclusion of 'Order_Relation_More_FP' into 'Order_Relation'

liquidated 'Equiv_Relations_More' -- distinguished between choice-dependent parts and choice-independent parts

compile (importing 'Metis' or 'Main' would have been an alternative)

dissolved 'Fun_More_FP' (a BNF dependency)

moved lemmas from 'Fun_More_FP' to where they belong

moved 'Zorn' into 'Main', since it's a BNF dependency

adapted to move of Wfrec

moved Wfrec to Main, since it is a dependency of cardinals, hence BNFs

added \<newline> symbol, which is used for char/string literals in HOL;

general notion of auxiliary bounds within context; revert_bounds as part of regular unparse_term; avoid special variants of Syntax.string_of_term in Simplifier (e.g. relevant for add-on tracing);

merged

fall-back on old Z3_NON_COMMERCIAL, which simplifies automatic test environments like isatest and mira;

tuned text

tuned

automatically solve proof obligations produced for code equations

use 'disc_exhausts' property both from types on which 'case's take place and on return type

activation of Z3 via "z3_non_commercial" system option (without requiring restart);

tuned;

use the right context in 'unfold_thms id_def'

repaired 'ctr' tactic w.r.t. 'split'

tuned

NEWS;

proper context for clear_simpset: preserve dounds, depth; dismantled obsolete debug_bounds/check_bounds;

clarified context;

tuned signature; clarified context;

tuned signature;

check_hyps when attributes are applied;

more accurate context;

reactivate Thm.check_hyps, after adapting AFP/Datatype_Order_Generator (see AFP/b7e389b5765c);

check_hyps for attribute application (still inactive, due to non-compliant tools); bypass check_hyps for locale expressions, where assumptions are not necessarily declared in intermediate situations;

tuned signature;

shot in the dark to make LaTeX happy again

provide default name in splitted representation

dropped legacy alias feature

merged

disable Thm.check_hyps for now, due to remaining problems with AFP/Datatype_Order_Generator and AFP/Psi_Calculi (because of HOL-Nominal 'equivariance');

more elementary management of declared hyps, below structure Assumption; Goal.prove: insist in declared hyps; Simplifier: declare hyps via Thm.assume_hyps; more accurate tool context in some boundary cases;

more accurate context;

tuned;

explicit check of background theory;

basic ordinal arithmetic and cardinals library extension (not relevant for BNFs)

correctly extract code RHS, with loose bound variables

cope gracefully with missing ctr equations by plugging in 'False ==> ...'
