Wed, 01 Jul 2015 22:37:49 +0200 wenzelm split multi-goals as usual (outermost Pure.conjunction only);
Wed, 01 Jul 2015 22:11:23 +0200 wenzelm clarified prems: full subgoal is imported in any case, to avoid remaining schematic variables;
Wed, 01 Jul 2015 21:57:21 +0200 wenzelm proper state after qed;
Wed, 01 Jul 2015 21:29:57 +0200 wenzelm support for subgoal focus command;

Fri, 06 Mar 2015 15:58:56 +0100 wenzelm Thm.cterm_of and Thm.ctyp_of operate on local context;
Thu, 05 Mar 2015 13:28:04 +0100 wenzelm tuned -- more explicit use of context;

Sat, 08 Nov 2014 21:31:51 +0100 wenzelm optional proof context for unify operations, for the sake of proper local options;
Tue, 31 Dec 2013 14:29:16 +0100 wenzelm proper context for norm_hhf and derived operations;

Fri, 11 Dec 2009 20:43:41 +0100 wenzelm Subgoal.FOCUS etc.: resulting goal state is normalized as usual for resolution;

Thu, 30 Jul 2009 17:54:57 +0200 wenzelm retrofit: more precise handling of locally introduced schematic variables (avoid zero_var_indexes);

Thu, 30 Jul 2009 11:23:17 +0200 wenzelm focus: more precise treatment of schematic variables, only the "visible" part of the text is fixed;
Sun, 26 Jul 2009 20:57:19 +0200 wenzelm added focus_params/FOCUS_PARAMS, which focus on the parameter prefix only;
Sun, 26 Jul 2009 19:38:02 +0200 wenzelm retrofit: actually handle schematic variables -- need to export into original context;
Sun, 26 Jul 2009 13:12:54 +0200 wenzelm advanced retrofit, which allows new subgoals and variables;
Wed, 24 Jun 2009 21:28:02 +0200 wenzelm renamed Variable.import_thms to Variable.import (back again cf. ed7aa5a350ef -- Alice is no longer supported);
Mon, 16 Mar 2009 23:36:55 +0100 wenzelm provide Simplifier.norm_hhf(_protect) as regular simplifier operation;
