Target "test" now depends on examples files

Target "test" now depends on examples files

fixed a bug in POLY.ML: delete_file didn't close streams; added function pwd to get current working directory

renamed hard-quant.ML to hardquant.ML

renamed int-prover.ML to intprover.ML, used exact theory names for use_thy

renamed int-prover.ML to intprover.ML, used exact theory names in ROOT.ML

now forbids semicolons in the body of br, etc. No longer requires it to end the line.

Minor changes; addition of counit.ML

change of my address

Added documenation of change_simp.

renamed co_inductive.ML to coinductive.ML

renamed twos-compl.ML to twos_compl.ML

renamed some files

commented out install_pp for term, typ

added infix delsimps

added function del_simps

deletion of obsolete/private files; update of README

minor changes e.g. datatype_elims

now uses datatype_intrs and datatype_elims

updated version to October 93

no longer specifies "-h 15000". Instead $ISABELLECOMP should include any switch settings.

corrected some spelling mistakes; removed a bug that made it impossible to read theories that don't have a ML file; extended syntax for bases in syntax.ML: a string can be used to specify a theory that is to be read but is not merged into the base (useful for pseudo theories used to document the dependencies of ML files)

added white-space; made ~: a fake infix;

added white-space; made ~= a fake infix;

removed a bug that occured when a path was specified for use_thy's parameter and the theory was created in a .ML file

ZF/ex/tf,tf_fn: renamed the variable tf to f everywhere

renamed some files

added -h 15000 for Poly/ML in Makefile, changed ROOT.ML for new Readthy

changes in Readthy: - reads needed base theories automatically - keeps a time stamp for all read files - update function - checks for cycles - path list that is searched for files - reads theories that are created in .ML files - etc.

delete_file now has type string -> unit in both NJ and POLY, use of Pure/Thy/ROOT has been moved to the end of Pure/ROOT again

changes for new Readthy

sample datatype defs now use datatype_intrs, datatype_elims

ZF/ind-syntax/fold_con_tac: deleted, since fold_tac now works ZF/intr-elim/elim_rls: applied make_elim to succ_inject! ZF/fin: changed type_intrs in inductive def ZF/datatype/datatype_intrs, datatype_elims: renamed from data_typechecks, data_elims ZF/list: now uses datatype_intrs

tactic/fold_tac,fold_goals_tac: now handle critical pairs on the right sides of the defs

goals/print_top,prepare_proof: now call \!print_goals_ref

Pure/drule/print_goals_ref: new, for Centaur interface Pure/tctical/tracify,print_tac: now call !print_goals_ref Pure/goals/print_top,prepare_proof: now call !print_goals_ref

/NJ,POLY/delete_file: new

simpdata/basify: now calls new fastype_of

logic/mk_equals,mk_flexpair: now calls fastype_of instead of type_of. So it no longer checks t properly -- but it never checked u anyway, and all existing calls are derived from certified terms...

now calls new fastype_of in three places

Pure/Syntax/printer/is_prop: now calls fastype_of1

Pure/term/fastype_of1: renamed from fastype_of Pure/term/fastype_of: new, takes only one argument (like type_of) Pure/Syntax/printer/is_prop: now calls fastype_of1 Pure/pattern: now calls new fastype_of in three places Pure/logic/mk_equals,mk_flexpair: now calls fastype_of instead of type_of. So it no longer checks t properly -- but it never checked u anyway, and all existing calls are derived from certified terms...

renamed: S4.thy to s4.thy, S43.thy to s43.thy, T.thy to t.thy

renamed: terms.* to term.*, types.* to type.*, wf.* to wfd.*

file_info now returns a string that does not contain the path/filename (so the string doesn't change when the relative path does)

added parser.ML, install_pp.ML

ZF/ex/tf/tree,forest_unfold: streamlined the proofs Updated other inductive def examples as per changes in the package.

ZF/ind-syntax/refl_thin: new ZF/intr-elim: added Pair_neq_0, succ_neq_0, refl_thin to simplify case rules ZF/sum/Inl_iff, etc.: tidied and proved using simp_tac ZF/qpair/QInl_iff, etc.: tidied and proved using simp_tac ZF/datatype,intr_elim: replaced the undirectional use of sum_univ RS subsetD by dresolve_tac InlD,InrD and etac PartE

classical/swap_res_tac: recoded to allow backtracking

Added gen_all to simpdata.ML.

renamed ordinal.thy to ord.thy

renamed ordinal.ML to ord.ML

renamed ordinal.* to ord.*

"The" now a binder, removed translation; improved encoding and translations of tuples; added parse rules for -> and *, removed ndependent_tr;

removed ndependent_tr (no longer needed, use _K);
