2010-08-22 ago simplified Command.status again, reverting most of e5eed57913d0 (note that more complex information can be represented with full markup reports);
2010-08-22 ago tuned signature;
2010-08-22 ago renamed Markup_Tree.Node to Text.Info;
2010-08-22 ago Isabelle_Hyperlinks: select relevant information directly from Markup_Tree, without intermediate RefInfo;
2010-08-22 ago Document_View.text_area_extension: select relevant information directly from Markup_Tree, without intermediate TypeInfo;
2010-08-22 ago Command.State: accumulate markup reports uniformly;
2010-08-19 ago parameterized type Markup_Tree.Node;
2010-08-19 ago Command.status: full XML.Tree, i.e. Markup with potential "arguments";
2010-08-18 ago more efficient Markup_Tree, based on branches sorted by quasi-order;
2010-08-18 ago decode Isabelle symbol positions in one spot;
2010-08-16 ago simplified command status: interpret stacked markup on demand;
2010-08-15 ago some derived operations on Text.Range;
2010-08-15 ago specific types Text.Offset and Text.Range;
2010-08-14 ago Snapshot.state: fall back on Command.empty_state -- looked-up command might be unavailable due to editing divergence;
2010-08-14 ago tuned;
2010-08-13 ago explicit Document.State value, instead of individual state variables in Session, Command, Document;
2010-08-12 ago more basic notion of unparsed input;
2010-08-12 ago clarified "state" (accumulated data) vs. "exec" (execution that produces data);
2010-08-12 ago misc tuning and simplification;
2010-08-12 ago specific command state;
2010-08-12 ago specific Session.Commands_Changed;
2010-08-11 ago represent document ids by (long) int, to benefit from the somewhat faster Inttab in ML (LinearSet in Scala is invariably indexed by native object ids);
2010-08-06 ago avoid null in Scala;
2010-08-05 ago simplified/refined document model: collection of named nodes, without proper dependencies yet;
2010-06-13 ago tuned Command.toString -- preserving uniqueness allows the Scala toplevel to print Linear_Set[Command] results without crashing;
2010-05-30 ago more detailed token markup, including command kind as sub_kind;
2010-05-29 ago tuned messages;
2010-05-28 ago accumulate only local results -- no proper history support yet;
2010-05-27 ago Command.toString: include id for debugging;
2010-05-20 ago explicit Command.Status.UNDEFINED -- avoid fragile/cumbersome treatment of Option[State];
2010-05-05 ago some rearrangement of Scala sources;
