2015-06-01 wenzelm 2015-06-01 tuned;
2015-05-12 nipkow 2015-05-12 this warning is hardly useful but produces noisy markers in the jedit interface
2015-03-13 nipkow 2015-03-13 rhs of eqn is only eta- but not beta-eta-contracted; hence the latter is performed explicitly if needed

2014-03-21 wenzelm 2014-03-21 more qualified names;
2014-02-20 wenzelm 2014-02-20 tuned signature; tuned message;
2014-02-10 wenzelm 2014-02-10 more elementary put_simpset: exchange the simplifier configuration outright, which is particularly relevant concerning cumulative depth, e.g. for Product_Type.split_beta in the subsequent example: lemma "P (\<lambda>s. (case s of (x, y) \<Rightarrow> c))" using [[simp_depth_limit = 1]] apply simp oops
2014-02-04 Lars Hupel 2014-02-04 interactive simplifier trace: new panel in Isabelle/jEdit to inspect and modify simplification state
2014-01-17 wenzelm 2014-01-17 back to conditional tracing instead of noisy warning (see also 00e849f5b397): these incidents happen occasionally;
2014-01-17 wenzelm 2014-01-17 tuned;
2014-01-17 wenzelm 2014-01-17 clarified Simplifier diagnostics -- simplified ML; unconditional warning for structural mistakes (NB: context of running Simplifier is not visible, and cond_warning ineffective);
2014-01-15 wenzelm 2014-01-15 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);
2014-01-12 wenzelm 2014-01-12 proper context for clear_simpset: preserve dounds, depth; dismantled obsolete debug_bounds/check_bounds;
2014-01-12 wenzelm 2014-01-12 tuned signature;
2014-01-10 wenzelm 2014-01-10 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;

2013-12-12 wenzelm 2013-12-12 clarified Trace_Ops: global theory data avoids init of simpset in Pure.thy, which is important to act as neutral element in merge;
2013-12-12 wenzelm 2013-12-12 generic trace operations for main steps of Simplifier;
2013-12-12 wenzelm 2013-12-12 tuned signature;

2013-05-30 wenzelm 2013-05-30 tuned signature;
2013-05-20 wenzelm 2013-05-20 more rigorous check of simplifier context; tuned;
2013-05-20 wenzelm 2013-05-20 tuned;
2013-05-16 wenzelm 2013-05-16 tuned signature -- depend on context by default;

2013-04-04 nipkow 2013-04-04 removed unnerving (esp in jedit) and pointless warning
2013-03-30 wenzelm 2013-03-30 amended uncond_skel to observe notion of cong_name properly -- may affect simplification with Free congs;

2012-09-29 wenzelm 2012-09-29 more explicit Syntax_Trans.mark_bound_abs/mark_bound_body: preserve type information for show_markup;
