2011-03-22 wenzelm 2011-03-22 statespace syntax: strip positions -- type constraints are unexpected here;
2011-03-22 wenzelm 2011-03-22 datatype case_tr: strip positions -- type constraints are unexpected despite the "any" category in "case_syn";
2011-03-22 wenzelm 2011-03-22 support for encoded positions (for id_position, longid_position) as pseudo type-constraints -- still inactive; simplified/generalized abs_tr/binder_tr: allow iterated constraints, stemming from positions; Ast.pretty_ast: special treatment of encoded positions; eliminated Ast.str_of_ast in favour of uniform Ast.pretty_ast;
2010-09-12 wenzelm 2010-09-12 eliminated aliases of Type.constraint;
2010-05-31 wenzelm 2010-05-31 modernized some structure names, keeping a few legacy aliases;
2010-04-29 wenzelm 2010-04-29 uniform decoding of fixed/const syntax entities, allows to pass "\<^fixed>foo__" through the syntax layer (supersedes 1b7109c10b7b);
2010-04-28 wenzelm 2010-04-28 get_sort: minimize sorts given in the text, while keeping those from the context unchanged (the latter are preferred); tuned;

2008-06-18 wenzelm 2008-06-18 added type_constraint (formerly in type_infer.ML, which is now loaded later);
2008-06-13 wenzelm 2008-06-13 map_const: soft version, no failure here (recovers hiding of consts, because a hidden name is illegal and rejected later);
2008-04-17 wenzelm 2008-04-17 moved default token translations to proof_context.ML, if all fails the pretty printer falls back on plain output;
2008-02-04 wenzelm 2008-02-04 *** MESSAGE REFERS TO 1.29 and 1.44 *** sort_of_term: be permissive about _class *output* markers, to allow print translations invoke this function as well;

2005-02-13 skalberg 2005-02-13 Deleted Library.option type.
2004-06-21 kleing 2004-06-21 Merged in license change from Isabelle2004
2004-06-09 wenzelm 2004-06-09 removed separate logtypes field of syntax;
2004-05-29 wenzelm 2004-05-29 tuned _dummy_ofsort syntax;
2003-11-06 schirmer 2003-11-06 Records: - Record types are now by default printed with their type abbreviation instead of the list of all field types. This can be configured via the reference "print_record_type_abbr". - Simproc "record_upd_simproc" for simplification of multiple updates added (not enabled by default). - Tactic "record_split_simp_tac" to split and simplify records added. - Bug-fix and optimisation of "record_simproc". - "record_simproc" and "record_upd_simproc" are now sensitive to quick_and_dirty flag.
2003-07-02 nipkow 2003-07-02 Type antiquotations do not use the bracket syntax by default any longer.

2000-12-01 wenzelm 2000-12-01 no_brackets mode;
2000-06-14 wenzelm 2000-06-14 tuned tappl syntax;

1997-02-24 wenzelm 1997-02-24 added "_" syntax for dummyT;
1997-02-06 wenzelm 1997-02-06 improved comments; raw_term_sorts: improved handling of sort constraints (consistency); added term_of_sort; renamed "_emptysort" to "_topsort"; preparations for marking of class idts;
1996-12-18 oheimb 1996-12-18 little improvement for the handling of sort constraints: two non-identical explicit constriants are considered equal if they give the same set in different enumerations, e.g. {term,ord,ord} = {ord,term}
1996-02-16 paulson 1996-02-16 Elimination of fully-functorial style. Type tactic changed to a type abbrevation (from a datatype). Constructor tactic and function apply deleted.
1994-12-08 clasohm 1994-12-08 changed Pure's grammar and the way types are converted to nonterminals
1994-10-12 wenzelm 1994-10-12 removed old comment;
