merged

added code certificates

tuned code equations

Matrices form a semiring with 0

incorporate "proofdocument" part into main Isabelle/Pure.jar -- except for html_panel.scala, which depends on external library (Lobo/Cobra browser);

ignore some src/Tools/jEdit stuff;

merged with converted/relocated copy of http://isabelle.in.tum.de/repos/isabelle-jedit/rev/93d884afa74b

more timing;

more tobust treatment of Document.current_state; some timing;

new unparsed span for text right after existing command; tuned;

Outer_Lex.is_ignored;

simplified Text_Edit;

eliminated strange mutable var commands; removed_commands: refer to old commands; misc tuning;

updated header;

eliminated obsolete isabelle.proofdocument.Token;

do not override Command.hashCode -- which was inconsistent with eq anyway; unparsed: no id, commands observe pointer equality; actually invoke edit_commands; more correct doc_edits; tuned;

renamed Command.content to source; reorganization of document parsing, using command spans etc. -- initial setup;

further tuning of command_start;

refrain from poking blink rate -- might get stuck in invisible state;

eliminated Command.stop, which tends to case duplicate traversal of commands;

iterators for ranges of commands/starts -- avoid extra array per document; try/finally for saved_color; misc tuning;

tuned document changes;

misc tuning and clarification of Document/Change;

adhoc reset of blink rate; bind "console" instance;

provide global "Isabelle" within interpreter loop -- using import instead of val avoids pontential conflicts with later import isabelle.jedit._;

redirect scala.Console output during interpretation; misc tuning;

bind "session"; added printInfoMessage; added stop -- re-inits the interpreter;

export isabelle_system, e.g. for use via "session" in Isabelle/Scala interpreter;

removed unused var plugin;

pass all jEdit jars to compiler as classpath -- to enable proper referencing of application name space; reduced predefined values, which take time and are static anyway;

provide some bindings of jEdit values; plain color for input;

more precise prompt etc.;

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;
