proper context for Syntax.parse_token;

prefer Context_Position.report where a proper context is available -- notably for "inner" entities;

explicitly distinguish Output.status (essential feedback) vs. Output.report (useful markup);

fixed odd runtime type error, which appears to have escaped the scala-2.8.0.final compiler;

YXML.parse: refrain from interning, let XML.Cache do it (partially);

cache_string: store trimmed string value;

simple_dialog: allow scala.swing.Component as well;

simplified some Markup;

simplified type XML.Tree: embed Markup directly, avoid slightly odd triple; XML.cache_tree: actually store XML.Text as well; added Isabelle_Process.Result.properties;

more robust treatment of Markup.token;

simplified type XML.tree: embed Markup.T directly, avoid slightly odd triple;

concentrate structural document notions in document.scala; tuned;

maintain editor history independently of Swing thread, which is potentially a bottle-neck or might be unavailable (e.g. in batch mode);

tuned;

more explicit model of pending text edits;

more explicit treatment of Swing thread context; Document_Model.snapshot: require Swing thread;

replaced individual Document_Model history by all-inclusive one in Session; Document_Model: provide thy_name externally, i.e. by central Isabelle plugin; tuned;

misc tuning and clarification;

avoid null in Scala; tuned comments;

updated keywords;

removed obsolete Goal.local_future_enforced: Toplevel.run_command is no longer interactive, so Goal.local_future_enabled is sufficient (cf. 349e9223c685 and e07dacec79e7);

merged

merged

quotient types registered as codatatypes are no longer quotient types

added a friendly warning

extend the scope of limitation about nonconservative extensions

improved "merge_type_vars" option: map supersorts to subsorts, to avoid distinguishing, say, "{}", and "HOL.type"

Remove duplicate locale activation code; performance improvement.

added record field

added "whack"
