renamed rtype to typerep

added fold_rev; tuned dest, keys;

added del_node, which is more efficient for sparse graphs;

IntGraph.del_node;

join_results: special case for empty list, works without multithreading;

added dest_deriv, removed external type deriv; misc tuning of internal deriv; more substantial promise/fulfill; promise_ord: reverse order on serial numbers; removed unused is_named; get_name: unfinished proof term;

added conditional add_oracles, keep oracles_of_proof private; added fulfill; removed unused is_named; tuned some table operations;

Thm.proof_of;

Added coherent logic prover.

New prover for coherent logic.

Added setup for coherent logic prover.

Added examples for coherent logic prover.

Examples for coherent logic prover.

made the perm_simp tactic to understand options such as (no_asm)

type thm: fully internal derivation, no longer exported; incorporate former deriv.ML as internal abstract type; added rudimentary promise interface; tuned; added is_named (does not require finished derivation);

added is_finished;

added Promise constructor, which is similar to Oracle but may be replaced later; added promise_proof; export min_proof, mk_min_proof; moved infer_derivs to thm.ML as derive_rule0/1/2; tuned oracles_of_proof; added is_named;

removed deriv.ML which is now incorporated into thm.ML;

added reject_draft;

type thm: fully internal derivation, no longer exported;

generic quickcheck framework

TEMPORARY: make batch run happy

absolute Library path

different session branches for HOL-Plain vs. Plain

temporary workaround for class constants

corrected sort intersection

some steps towards generic quickcheck framework

fixed headers

added some fragments from website

made SML/NJ happy;

Isar toplevel editor model.

future tasks: support boolean priorities (true = high, false = low/irrelevant);

output_sync is now public;

added props_text (from isar_syn.ML);

moved Isar editor commands from isar_syn.ML to isar.ML; P.props_text;

moved Isar editor commands from isar_syn.ML to isar.ML;

added Isar/isar.scala;

avoid using implicit assumptions

add theory graph to ZF document

made SMLNJ happy

jar: include sources;

tuned;

eval_term: CRITICAL due to eval_result; simplified oracle interface;

begin_theory: Theory.checkpoint for immediate uses ensures that ML evaluation always starts with non-draft @{theory};

updated generated file;

simplified oracle interface;

show: non-critical testing;

added deriv.ML: Abstract derivations based on raw proof terms.

termination prover for "fun" can be configured using context data.

updated generated file;

unchecked $ISABELLE_HOME_USER/etc/settings;

use_text/use_file now depend on explicit ML name space;

threads work only for Poly/ML 5.2 or later; global ML bindings are now thread-safe;

* ML bindings produced via Isar commands are stored within the Isar context. * Command 'ML_prf' is analogous to 'ML' but works within a proof context.

added ML_prf;

updated generated file;

added inherit_env;

added map_contexts;

ML_prf: inherit env for all contexts within the proof;

shutdown only if Multithreading.available;
