FundefLib.try_proof : attempt a proof and see if it works

added lemmas

inner_syntax markup is back;

disabled inner_syntax markup for now;

added read_token -- with optional YXML encoding of position; tuned parse operations: print position instead of echoing input (now encoded!); do not export obsolete read operation;

parse_token: use Syntax.read_token, pass full position information;

tuned;

map_default: more explicit scope;

datatype lexicon: alternative representation using nested Symtab.table;

simplified Antiquote signature;

more precise positions due to SymbolsPos.implode_delim; added source' for SymbolPos.T;

simplified Antiq: regular SymbolPos.text with position; renamed read_arguments to read_antiq; tuned;

renamed SymbolPos.scan_position to SymbolPos.scan_pos; implode/explode: explicit type text = string; added implode_delim; explode: Position.reset_range;

only increment column if valid; more robust handling of invalid entries; clarified line/line_file: no column here; added start = (1, 1); added reset_range; tuned;

install_pp Position.T;

Position.start;

SymbolPos.explode;

improved position handling due to SymbolPos.T;

improved position handling due to SymbolPos.T; SymbolPos.scan_comment; tuned;

Antiquote.read/read_arguments;

updated type of nested sources;

improved position handling due to SymbolPos.T; SymbolPos.scan_comment_body; tuned;

adapted Scan.extend_lexicon/merge_lexicons;

renamed scan_antiquotes to read; renamed scan_arguments to read_arguments; improved position handling due to SymbolPos.T; tuned;

export not_eof;

reorganized lexicon: allow scanning of annotated symbols, tuned representation and interfaces;

advance: single argument (again); added range; tuned;

Symbols with explicit position information.

added General/symbol_pos.ML;

Interpretation command (theory/proof context) no longer simplifies goal.

added lemma

made SML/NJ happy;

Reverted last change, since it caused incompatibilities.

fall back on P.term_group, to avoid problems with inner_syntax markup (due to CodeName.read_const_exprs);

T.end_position_of; tuned;

adapted Antiq;

parse_sort/typ/term/prop: report markup;

sort/typ/term/prop: inner_syntax markup encodes original source position; added typ/term/prop_group (without inner_syntax markup);

removed obsolete range_of (already included in position); added end_position_of; replaced scan_string by scan_quoted (which keeps quotes and includes alt_string as well); misc tuning;

report markup;

Antiq: inner vs. outer position; scan_antiq: use T.scan_quoted;

of_properties: observe Markup.position_properties';

added position_properties'; renamed prop to proposition; added attribute, method;

token: maintain of source, which retains original position information; removed count/counted, advance position via scanned source;

moved OuterLex.count here;

improved recover: also resync on symbol/comment/verbatim delimiters;

advance: operate on symbol list (less overhead);

added token;

fix HOL/ex/LexOrds.thy; add to regression

added report;

removed axiom; added fact, dynamic_fact, prop;

get_fact: report position;

Facts.lookup: return static/dynamic status;

position scanner: encode token range;

added encode_range; tuned;

added end_line, end_column properties;

meta_subst: xsymbols make it work with clean Pure;

abstract type Scan.stopper, position taken from last input token;

abstract type Scan.stopper;

abstract type stopper, may depend on final input;

removed obsolete apply_theorems(_i);

tuned signature; eliminated obsolete pervasives;

removed obsolete note_thms_cmd;

simplified defer_recdef(_i): plain facts via Attrib.eval_thms;

tuned description;

replaced mercurial.cgi by hgwebdir.cgi, resulting in http://isabelle.in.tum.de/repos/isabelle/

Quoted terms in consts_code declarations are now preprocessed as well.

Exported eval_wrapper.

- corrected bogus comment for function inst_conj_all - tuned function obtain_fresh_name

removed dead code

simplified prepare_command;

Isar.command: explicitly set transaction position, as required for prepare_command errors; adapted Isabelle.command;

Updated locale tests.

Generalised polynomial lemmas from cring to ring.

Removed import and lparams from locale record.

made setsum executable on int.

Tuned (for the sake of a meaningless log entry).

New locales for orders and lattices where the equivalence relation is not restricted to equality.

added hint about writing "x : set xs".

simple lifters

dropped imperative monad bind

facts_of

improved morphism

SML_imp, OCaml_imp

clarified

tuned

Zorn's Lemma for partial orders.

Definitions and some lemmas for reflexive orderings.

Lemmas added

New theory on divisibility.

Renamed theorems; New theory on divisibility.

New theorems on summation.

Unit_inv_l, Unit_inv_r made [simp].

New theory on divisibility; Restructured presentation.

Unit_inv_l, Unit_inv_r made [simp]; Renamed theorems; New theory on divisibility.
