tuned proofs

towards showing " in the tutorial

tuned proof in order to avoid warning message

remove unnecessary qualifiers on names

add lemma Suc_1

merged

Require "For" keyword to be followed by at least one whitespace, to avoid that identifiers starting with "For" are interpreted as traceability information

normalize defs (again, cf. 008b7858f3c0);

some context examples;

retain literal non-HHF assumptions, to facilitate re-import in Generic_Target.import_export_proof;

another attempt to avoid duplication of global vs. local syntax (reminiscent of old fork_mixfix);

export into target context (again), to retain its 'defines' (e.g. abbreviation lcoeff in theory HOL/Algebra/UnivPoly);

better drop background syntax if entity depends on parameters; more direct Type_Infer_Context.const_type instead of Syntax.check_term, which expands abbreviations (and potentially more);

more uniform abbrev vs. define;

tuned;

clarified generic_const vs. close_schematic_term;

tuned;

more uniform theory_abbrev with const_declaration;

avoid const_declaration in aux. context (cf. locale_foundation);

clarified background_foundation vs. theory_foundation (with const_declaration);

tuned;

more general standard_declaration; generic const declaration, which is applied to nested targets (named target only);

better restore after close_target;

tuned;

clarified standard_declaration vs. theory_declaration;

smarter generic_const: plain alias for non-dependent case (e.g. prospective datatype or record syntax);

tuned;

tuned;

tuned signature;

misc tuning and simplification;

better restore to first target, not last target;

refined define/abbrev: allow extra fixes in aux. context vs. bottom target (NB: export_term expands defined variables, leaving fixed ones);

more general Local_Theory.restore, allow any nesting level;

new tutorial

New manual Programming and Proving in Isabelle/HOL

add simp rules for dvd on negative numerals

merged, manually resolving conflicts due to session renaming (cf. 6488c5efec49)

clarified terminology; added reference to bundle component

less modest NEWS; CONTRIBUTORS

renamed import session back to Import, conforming to directory name; NEWS

more precise IsaMakefile (eg. see HOL-Algebra);

more keywords;

merged

merged

removed old HOL4 import -- corresponding exporter is lost, code is broken, no users known, maintenance nightmare

Modernized HOL-Import for HOL Light

merged

adapted Mira configuration to dd04c8173bb2.

removed Nat_Numeral.thy, moving all theorems elsewhere

less brutal return from function, to allow caller to report error;

more general context command with auxiliary fixes/assumes etc.;

more precise type annotation (cf. 6523a21076a8);

nothing specific about named target;

clarified Generic_Target.notes: always perform Attrib.partial_evaluation; more uniform Generic_Target.theory_notes/locale_notes: apply facts to all target contexts;

added Attrib.global_notes/local_notes/generic_notes convenience;

simplified;

tuned signature;

clarified Named_Target.target_declaration: propagate through other levels as well; tuned signature;

Local_Theory.map_contexts with explicit level indication: 0 = main target at bottom; Local_Theory.target refers to bottom; tuned signature;
