2014-07-23 wenzelm 2014-07-23 clarified module name: facilitate alternative GUI frameworks;
2014-04-25 wenzelm 2014-04-25 clarified Session.Consumer, with Session.Outlet managed by dispatcher thread; eliminated old actors;
2014-04-22 wenzelm 2014-04-22 avoid "Adaptation of argument list by inserting ()" -- deprecated in scala-2.11.0;
2014-04-02 wenzelm 2014-04-02 more explicit iterator terminology, in accordance to Scala 2.8 library; clarified Graph.keys_iterator vs. Graph.keys, with subtle change of semantics; tuned output;
2014-03-27 wenzelm 2014-03-27 more careful treatment of multiple command states (eval + prints): merge content that is actually required; more standard Markup_Tree merge, including trivial cases;
2014-02-20 wenzelm 2014-02-20 tuned imports;
2013-11-21 wenzelm 2013-11-21 back to Status.FINISHED and immediate remove_overlay (reverting 6e69f9ca8f1c), which is important to avoid restart of print function after edits + re-assignment of located command; resolve sendback wrt. static command id, to allow active area even after exec_id is removed (cf. prune_delay);
2013-10-11 wenzelm 2013-10-11 more consistent state and GUI update, e.g. relevant for full-screen mode switch with its exit/init side-effect;
2013-10-11 wenzelm 2013-10-11 clarified Editor.current_command: allow outdated snapshot; more accurate Document_View.perspective based on current_command for proper state output (see also 88c6e630c15f and ef62204a126b);
2013-10-07 wenzelm 2013-10-07 clarified remove_overlay: always flush in order to make sure that apply_query can make a fresh start with the same arguments (see also 6e69f9ca8f1c) -- NB: print functions are idempotent;
2013-09-25 wenzelm 2013-09-25 explicit Status.REMOVED, which is required e.g. for sledgehammer to retrieve command of sendback exec_id (in contrast to find_theorems, see c2da0d3b974d);
2013-09-24 wenzelm 2013-09-24 skip ignored commands, similar to former proper_command_at (see d68ea01d5084) -- relevant to Output, Query_Operation etc.; tuned signature;
2013-09-24 wenzelm 2013-09-24 tuned;
2013-08-13 wenzelm 2013-08-13 more cleanup;
2013-08-12 wenzelm 2013-08-12 moved generic module to its proper place;
