define scala.home, for more robust startup of Scala tools, notably the compiler;

added jEdit Console and Scala compiler;

some attempts at Scala console plugin;

more precise treatment of document/state assigment;

more precise notion of bad messages;

use Text_Edit provided by Isabelle;

result.is_ready is not bad;

singleton status messages, with more precise patterns -- report bad messages;

back to explicit management of documents -- not as generic Session.Entity -- to avoid ill-defined referencing of new states; recent_document: require finished state assignment; explicitly typed Session.lookup_command;

slightly more uniform/robust handling of visible document; uniform changed_delay for view updates; misc tuning;

recovered explicit Changed.id (copy of future document) -- avoids premature joining of result; Change.ancestors: frugal iterator;

more explicit treatment of command/document state; misc tuning and clarification;

removed unused document_change bus;

tuned;

tuned;

misc tuning;

tuned Change: eliminated redundant copy of document id;

eliminated redundant session documents database; tuned;

use isabelle.Future; tuned;

renamed current_document to recent_document (might be a bit older than current_change); Change: explicit future value of Document.Change instead of implicit lookup in Session database; Document_Model: apply Document.text_edits here (as future);

renamed Proof_Document to Document;

tuned dialog;

improved dialog;

basic setup for synchronous / modal (!) prover startup;

tuned signature;

register Proof_Document instances as session entities -- handle Markup.EDIT messages locally;

tuned signature of isabelle.Position;

maintain generic session entities -- cover commands, states, etc. (but not yet documents);

unified Command and Command_State, eliminated separate Accumulator; Command.finish_static: idempotent transition from static to dynamic mode, taking snapshot of final state (which will never change later);

removed experimental history panel;

more explicit modeling of Command and Command_State as Session.Entity; misc tuning;

updated;

tuned;

tuned caret_listener/selected_command;

misc tuning;

eliminated global Session.document_0 -- did not work due to hardwired id; more precise Session.begin_document, avoid race on var prover; replaced slightly odd Session.document_versions by Sassion.documents table (cf. src/Pure/Isar/isar_document.ML); simplified edit_document in ML: initial empty command is identified by ""; misc tuning;

tuned;

tuned;

Standard_System;

slightly larger stack size -- default seems to be as low as 256k;

back to activate=startup (again) -- ensure that Isabelle_Encoding refers to valid Isabelle.system;

adapted to class Outer_Syntax;

renamed session.info to session.root;

tuned;

just one variable for outer syntax keywords and completion;

added isabelle-session mode for session.info files;

tuned keywords;

sort completions by plain string order;

cache results;

imitate PG 4 colors;

tuned;

simplified Isabelle_Process.Result;

explicit object Session.Global_Settings; misc tuning;

actually use JEDIT_JAVA_OPTIONS from settings, not ..._ARGS;

some explicit Swing_Thread guards;

direct apply for Document_Model and Document_View;
