more operations on Time, Timing;

reverted slip introduced in f738e6dbd844

added 'print_defn_rules' command; tuned;

more item markup; tuned signature;

item markup for Proof_Context.pretty_fact; tuned signature;

obsolete, cf. Proof_Context.print_syntax;

paint bullet bar within text layer -- thus it remains visible with active selection etc.;

Pretty.item markup for improved readability of lists of items;

tuned message;

convenience check for vain instantiation

improved centering via strikethrough offset;

re-generated SMT certificates

new, simpler implementation of monomorphization; old monomorphization code is still available as Legacy_Monomorphization; modified SMT integration to use the new monomorphization code

ghost bullet via markup, which is painted as bar under text (normally space);

replace induction by hammer

merged

merged;

basic support for Pretty.item, which is considered as logical markup and interpreted in Isabelle/Scala, but ignored elsewhere (TTY, latex etc.);

maintain integer indentation during formatting -- it needs to be implemented by repeated spaces eventually; always round block indentation upwards, to ensure that text moves visually to the right of the "hanging" part;

tuned;

proper default browser info for interactive mode, notably thy_deps;

improved pretty printing for state set acom

Improvements to the print_dependencies command.

discontinued obsolete parallel_proofs_reuse_timing;

merged

separate isatest with skip_proofs, to give some impression of performance without most of the proofs;

merged

extra checkpoint to avoid stale theory in skip_proof context, e.g. in 'instance' proof;

tuned;

allow build with skip_proofs enabled -- disable it for sessions that would fail due to embedded diagnostic commands, for example;

more robust access Toplevel.proof_of -- prefer warning via Toplevel.unknown_proof over hard crash (notably for skipped proofs);

more liberal handling of skipped proofs;

explicit Toplevel.is_skipped_proof; tuned;

separate option editor_skip_proofs, to avoid accidental change of preferences for skip_proofs, which would invalidate batch builds;

more ambitious Goal.skip_proofs: covers Goal.prove forms as well, and do not insist in quick_and_dirty (for the sake of Isabelle/jEdit);

clarified Skip_Proof.cheat_tac: more standard tactic; clarified Method.cheating: check quick_and_dirty when it is actually applied;

tuned signature and module arrangement;

tuned;

tuned GUI;

centralized various multiset operations in theory multiset; more conversions between multisets and lists respectively

avoid odd foundational terms after interpretation; more uniform code setup

more uniform style for interpretation and sublocale declarations

merged

tuned session specification;

tuned proof;

tuned imports;

tuned proofs;

explicit sublocale dependency for Min/Max yields more appropriate Min/Max prefix for a couple of facts

merged

proper input event handling;

more standard imports;

more specific Entry painting; ignore theories with all commands below threshold;

tuned;

mixed theory/command entries; tuned;

dockable window for timing information;

no \FIXME macro for ProgProve (moved to book)

remove Metric_Spaces and move its content into Limits and Real_Vector_Spaces

rename eventually_at / _within, to distinguish them from the lemmas in the HOL image

move theorems about compactness of real closed intervals, the intermediate value theorem, and lemmas about continuity of bijective functions from Deriv.thy to Limits.thy

Series.thy is based on Limits.thy and not Deriv.thy
