2010-08-17 wenzelm 2010-08-17 tune;
2010-08-17 wenzelm 2010-08-17 added functor Linear_Set, based on former adhoc structures in document.ML; Linear_Set.delete_after (ML): actually delete table entries; Scala Linear_Set: clarified exceptions, according to ML version; simplified Document.node using Linear_Set; ML Document.edit: refer to start via NONE instead of no_id, according to Scala version;
2010-08-15 wenzelm 2010-08-15 document commands: maintain transition as future (wrt. potentially slow Outer_Syntax.prepare_command), refrain from second Toplevel.put_id;
2010-08-15 wenzelm 2010-08-15 renamed create_id to new_id;
2010-08-15 wenzelm 2010-08-15 more explicit / functional ML version of document model; tuned;
2010-08-14 wenzelm 2010-08-14 more basic Markup.parse_int/print_int (using signed_string_of_int) (ML); added convenient Markup.Int/Long objects (Scala); simplified "assign" message format -- explicit version id; misc tuning and simplification;
2010-08-14 wenzelm 2010-08-14 tuned;
2010-08-12 wenzelm 2010-08-12 clarified "state" (accumulated data) vs. "exec" (execution that produces data); generic type (ML) / Document.ID;
2010-08-11 wenzelm 2010-08-11 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);
2010-08-05 wenzelm 2010-08-05 simplified/refined document model: collection of named nodes, without proper dependencies yet; moved basic type definitions for ids and edits from Isar_Document to Document; removed begin_document/end_document for now -- nodes emerge via edits; edits refer to named nodes explicitly;
