isabelle: Changelog

adapting mutabelle; exporting more Quickcheck functions

making quickcheck's result value more formal; allowing more result information to be returned after timeout; adding output of timing information in quickcheck

changing timeout behaviour of quickcheck to proceed after command rather than failing; adding a test case for timeout

added Syntax.const_abs_tr' with proper eta_abs and Term.is_dependent; recovered printing of Hoare assign statements from 45d090186bbe;

dependent_tr': formal treatment of bounds after stripping Abs, although it should only happen for malformed terms, since print_translations work top-down;

added Term.is_open and Term.is_dependent convenience, to cover common situations of loose bounds;

more direct loose_bvar1; tuned;

update_name: more uniform treatment of type constraints (NB: type equality is hard to establish in parse trees);

added editor mode line;

isolate change of Proofterm.proofs in TPTP.thy from rest of session; qualified Proofterm.proofs to facilitate grepping;

list Isabelle tools via perl script, which is much faster that bash plumbing, especially on Cygwin; exclude backup files;

updated contributed components

Z3 non-commercial usage may explicitly be declined

export status function to query whether Z3 has been activated for usage within Isabelle

avoid illegal variable names, which then yield "Not an identifier" errors in "rename_tac"

move "TPTP" wrapper and "Sledgehammer as a tactic" to "HOL/ex" default to "e" rather than "vampire" since E is part of the Isabelle bundle

replace hardwired MIRABELLE_OUTPUT_PATH by temporary directory derived from ISABELLE_TMP_PREFIX and $$ -- old behaviour can be achieved by manually setting MIRABELLE_OUTPUT_PATH

standardized headers

generalized Caratheodory from algebra to ring_of_sets

add ring_of_sets and subset_class as basis for algebra

added first-order TPTP version of Nitpick to Isabelle, so that its sources stay in sync with Isabelle and it is easier to install new versions for SystemOnTPTP and CASC -- the tool is called "isabelle nitrox" but is deliberately omitted from the tool list unless the component is explicitly enabled, to avoid clutter

added "TPTP" theory with IsabelleP tactic, so that it is maintained alongside with Isabelle and that the CASC version of Isabelle is provided by Isabelle itself instead of being stored on the TPTP servers

remove lie from documentation

let SMT errors through -- the main reason for keeping them quiet was that the SMT bridge used to suffer from internal bugs, but these have been fixed for some time now

make Minimizer honor "verbose" and "debug" options better

fixed a printing problem for bounded quantifiers and bounded set operators in the case of tuples

moved some configurations to AFP, and fixed others

more selective strip_positions in case patterns -- reactivate translations based on "case _ of _" in HOL and special patterns in HOLCF;

enable inner syntax source positions by default (controlled via configuration option); disable source positions for HOLCF, due to special pattern translations;

binder_tr: more informative exception;

Hoare syntax: strip positions where they crash translation functions; re-unified some clones (!);

update_name_tr: more precise handling of explicit constraints, including positions;

statespace syntax: strip positions -- type constraints are unexpected here;

let syntax: reverted to plain "id", since translations cannot cope with constraints (notably position information);

datatype case_tr: strip positions -- type constraints are unexpected despite the "any" category in "case_syn";

tuned indendation and parentheses;

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;

pretty_string: proper handling of negative max_len;

added Lexicon.encode_position, Lexicon.decode_position;

clarified Syn_Trans.parsetree_to_ast and Syn_Trans.ast_to_term;

added judgement day configurations

another attempt to exec ISABELLE_GHC robustly (cf. d8c3b26b3da4, 994d088fbfbc);

eliminated unnecessary generated ROOT.ML

more precise dependencies

small test case for main mirabelle functionality, which easily breaks without noticing

propagate mirabelle failures properly; flatten obscure return code semantics of Perl system command to 0/1

mirabelle: create modified theory file in original location, to ensure that its dependencies can be found (cf. aa8dce9ab8a9)

adapting predicate_compile_quickcheck; tuned

adapting SML_Quickcheck

passing a term with free variables to the quickcheck tester functions instead of an lambda expression because this is more natural with passing further evaluation terms; added output of evaluation terms; added evaluation of terms in the exhaustive testing

extending the test data generators to take the evaluation terms as arguments

adding option of evaluating terms after invocation in quickcheck

adding eval option to quickcheck

handling a quite restricted set of functions in Quickcheck_Narrowing by an easy transformation

adding minimalistic setup and transformation to handle functions as data to enable naive function generation for Quickcheck_Narrowing

adding a simple datatype for representing functions in Quickcheck_Narrowing

extending code_int type more; adding narrowing instance for type int; added test case for int instance

translating bash output in quickcheck_narrowing to handle special characters; adding simple test cases

adding size as static argument in quickcheck_narrowing compilation

modernized specifications;

dropped unused structure aliases;

NEWS: structure Timing provides various operations for timing;

simplified various cpu_time clones (!): eliminated odd Exn.capture/Exn.release (no need to "stop" timing);

pure Timing.timing, without any exception handling; clarified cond_timeit: propagate interrupt without side-effect;

structure Timing: covers former start_timing/end_timing and Output.timeit etc; explicit Timing.message function; eliminated Output.timing flag, cf. Toplevel.timing; tuned;

pervasive cond_timeit;

eliminated dead code;

parallel preparation of document variants, within separate directories;

Present.init/finish/no_document are not thread-safe -- eliminated futile CRITICAL sections; tuned;

eliminated redundant doc_prefix1; tuned;

renamed doc_prefix2 to dump_prefix;

tuned terminology for document variants;

replaced File.check by specific File.check_file, File.check_dir; clarified File.full_path -- include parts of former Thy_Load.get_file; simplified Thy_Load.check_file -- do not read/digest yet; merged Thy_Load.check_thy/deps_thy -- always read text and parse header; clarified Thy_Header.read -- NB: partial Path.explode outside of args parser combinator; Thy_Info.check_deps etc.: File.read exactly once;

preencode value of "need" selectors in Kodkod bounds as an optimization

ignore "need" axioms for "nat"-like types

added "simp:", "intro:", and "elim:" to "try" command

optimize Kodkod axioms further w.r.t. "need" option

optimize Kodkod bounds of nat-like datatypes

more optimizations of bounds for "need"

optimize Kodkod bounds when "need" is specified

always destroy constructor patterns, since this seems to be always useful

reintroduced "show_skolems" option -- useful when too many Skolems are displayed

reword Nitpick's wording concerning potential counterexamples

prevent an exception if "card" is empty (e.g., "nitpick [card]")

add option to function to keep trivial ATP formulas, needed for some experiments

add option to relevance filter's "all_facts" function to really get all facts (needed for some experiments)

support non-ground "need" values

recover Isabelle symlink for public distribution, notably website;

standardized headers;

reworked Probability theory: measures are not type restricted to positive extended reals
