# 031de2be	08-Nov-2001	wenzelm <none@none>	* Isar/Pure: emulation of instantiation tactics (rule_tac, cut_tac, etc.) now consider the syntactic context of assumptions, giving a better chance to get type-inference of the arguments right (this is especially important for locales); * system: refrain from any attempt at filtering input streams; no longer support ``8bit'' encoding of old isabelle font, instead proper iso-latin characters may now be used;
# e761876a	06-Nov-2001	wenzelm <none@none>	* Isar/Pure: proper integration with ``locales''; unlike the original version by Florian Kammueller, Isar locales package high-level proof contexts rather than raw logical ones (e.g. we admit to include attributes everywhere); * Isar/Pure: theory goals now support ad-hoc contexts, which are discharged in the result, as in ``lemma (assumes A and B) K: A .''; syntax coincides with that of a locale body;

# 86104575	30-Oct-2001	wenzelm <none@none>	- 'induct' may now use elim-style induction rules without chaining facts, using ``missing'' premises from the goal state; this allows rules stemming from inductive sets to be applied in unstructured scripts, while still benefitting from proper handling of non-atomic statements; NB: major inductive premises need to be put first, all the rest of the goal is passed through the induction;
# 79672d26	30-Oct-2001	wenzelm <none@none>	- 'induct' method now derives symbolic cases from the rulified rule (before it used to rulify cases stemming from the internal atomized version); this means that the context of a non-atomic statement becomes is included in the hypothesis, avoiding the slightly cumbersome show "PROP ?case" form;

# d125639f	25-Oct-2001	wenzelm <none@none>	* Provers: 'simplified' attribute may refer to explicit rules instead of full simplifier context; 'iff' attribute handles conditional rules; * HOL/record: - provides cases/induct rules for use with corresponding Isar methods; - old "make" and "make_scheme" operation removed -- INCOMPATIBILITY; - new derived operations "make" (for adding fields of current record), "extend" to promote fixed record to record scheme, and "truncate" for the reverse; cf. theorems "derived_defs", which are not declared as simp by default; - internal definitions directly based on a light-weight abstract theory of product types over typedef rather than datatype;
