2014-03-08 wenzelm 2014-03-08 keep current context visibility for PIDE markup and completion (in contrast to 8e3e004f1c31): Attrib.check_src of 9dc5ce83202c should intern/report attributes once, which happens for local_theory in the (visible) auxiliary context;
2014-03-08 wenzelm 2014-03-08 modernized Attrib.check_name/check_src similar to methods (see also a989bdaf8121); proper context for global data; tuned signature;
2014-03-05 wenzelm 2014-03-05 clarified init_assignable: make double-sure that initial values are reset; more systematic reports for Args.syntax: indicate Args.$$$ quasi-keywords and suppress confusing completion of single symbols like ":", "|", "?";
2014-03-01 wenzelm 2014-03-01 clarified language markup: added "delimited" property; type Symbol_Pos.source preserves information about delimited outer tokens (e.g string, cartouche); observe Completion.Language_Context only for delimited languages, which is important to complete keywords after undelimited inner tokens, e.g. "lemma A pro";
2014-02-25 wenzelm 2014-02-25 more positions; tuned messages;
2014-01-25 wenzelm 2014-01-25 define basic attributes in user-space Pure.thy -- which provides better hyperlinks and may serve as example;

2013-06-27 wenzelm 2013-06-27 manage option "proofs" within theory context -- with minor overhead for primitive inferences;
2013-05-17 wenzelm 2013-05-17 renamed 'print_configs' to 'print_options';

2012-04-01 wenzelm 2012-04-01 added Attrib.global_notes/local_notes/generic_notes convenience;
2012-03-18 wenzelm 2012-03-18 maintain generic context naming in structure Name_Space (NB: empty = default_naming, init = local_naming); more explicit Context.generic for Name_Space.declare/define and derivatives (NB: naming changed after Proof_Context.init_global); prefer Context.pretty in low-level operations of structure Sorts/Type (defer full Syntax.init_pretty until error output); simplified signatures;
2012-03-13 wenzelm 2012-03-13 suppress vacous notes elements, with subtle change of semantics: 'interpret' no longer pulls-in unnamed facts "by fact";
2012-03-13 wenzelm 2012-03-13 improved attribute "abs_def" to handle object-equality as well;
2012-03-03 wenzelm 2012-03-03 canonical argument order for attribute application;

2011-11-21 wenzelm 2011-11-21 drop vacuous decls;

2011-11-17 wenzelm 2011-11-17 partial evaluation in invisible context;
2011-11-16 wenzelm 2011-11-16 retain mixed attributes as dynamic theorem expression, but disallow subsequent static rules;

2011-04-17 wenzelm 2011-04-17 markup attributes/methods via name space; eliminated obsolete markup;
2011-04-17 wenzelm 2011-04-17 report Name_Space.declare/define, relatively to context; added "global" variants of context-dependent declarations;
