new version of HOL/IMP with curried function application

new version of HOL with curried function application

added CPure (curried functions) and ProtoPure (ancestor of Pure and CPure)

added declaration of syntactic const "_abs";

Added initial /bin/csh line and comments

No longer calls maketest; instead, the Makefile writes the file test.

Uses "suffix substitution" to shorten macro definitions.

Re-organised to perform the tests independently. Now test is defined in terms of separate targets IMP, ex, etc. If ISABELLECOMP is set wrongly then "exit 1" causes the Make to fail. Defines the macro "LOGIC" to refer to the right command for running the object-logic. Uses "suffix substitution" to shorten macro definitions.

New example by Jacob Frost, tidied by lcp

Now prove_goalw_cterm calls print_sign_exn_unit, so that the rest of the error message ("The exception above was raised for...") will appear. And print_exn calls print_sign_exn_unit so that it can re-raise the SAME exception.

Updated the "version" variable (which was never done for Isabelle-94 revisions 1 and 2!)

Redefined functions to suppress redundant leading 0s and 1s

new in mixfix annotations: "' " (quote space) separates delimiters without adding extra white space for printing;

Added the exception handler handle _ => exit 1. This will catch all errors and force an exit with error code, causing Make to fail.

intro_tacsf now includes subsetI as an introduction rule. It is needed for rules like list_into_univ

Updated comment about list_subset_univ and list_into_univ.

exit: new, for use in Makefiles

Redefined arithmetic to suppress redundant leading 0s and 1s renamed the infix 2239 to the constant Bcons, as numerals eliminate the need for the infix.

Added integer numerals (mostly due to Markus Wenzel) renamed the infix 2239 to the constant Bcons, as numerals eliminate the need for the infix.

Proved zadd_left_commute and zmult_left_commute to define zadd_ac and zmult_ac. Deleted add_cong, add_kill and add_left_commute_kill as unused. Defined zadd_simps, zminus_simps, zmult_simps and added them to integ_ss.

New shell script for finding orphan .ML files (those with no .thy file)

added ExcludeThm; cleaned up Makefile; fixed isalpha bug (replaced by isalnum)

added check "length ts > 1" before printing ambiguity warning in infer_types

Improved test for looping rewrite rules.

replaced pair_ss by prod_ss

Improved check for looping conditional rewrite rules.

Tools description, largely taken from ../README

Moved description of tools to Tools/README

ord_iso_rvimage: new

Moved well_ord_Memrel, lt_eq_pred, Ord_iso_implies_eq_lemma, Ord_iso_implies_eq to top of file, as they do not require the other material. Simplified proof of ordertype_subset. Proved ordertype_eq: a short proof using deepen_tac! Deleted bij_ordermap_vimage and ordermap_Memrel "bij_ordermap_vimage and ordermap_Memrelf. [| f: bij(A,B); well_ord(B,r); x:A |] ==>\ \ ordermap(A,rvimage(A,f,r)) ` x = ordermap(B,r) ` (f`x)"; "\ ordermap(A,rvimage(A,f,r)) ` x = ordermap(B,r) ` (f`x)";i. [| Ord(i); j:i |] ==> ordermap(i,Memrel(i)) ` j = j" because ordertype_eq serves the same purpose. Proofs of bij_ordertype_vimage and ordertype_Memrel are now trivial.

qed is a utility that makes ML files store the defined theories in Isabelle's theorem database

Simplified proof of ord_iso_image_pred using bij_inverse_ss. Replaced not_well_ord_iso_pred_lemma by much simpler well_ord_iso_subset_lemma. Simplifed proof of well_ord_iso_unique_lemma using well_ord_iso_subset_lemma.
