removed unnecessary parentheses from the generated rules

Simplification: used Logic.occs instead of mem add_term_frees

changed string scanner so that newlines ('\n') are allowed and ignored inside strings

changed syntax of datatype declarations (curried types for constructor parameters)

renamed theorem "apfst" to "apfst_conv" to avoid conflict with function apfst from Pure/library.ML

Corrected faulty reference to Hindley-Milner type inference

Added recursion equations for foldl to list_ss.

Modified If_def to avoid ambiguity.

changed syntax of tuples from <..., ...> to (..., ...)

fixed bug: parent theory wasn't loaded if .thy file was completly read before (regardless of the .ML file)

fixed bug: HOL_build_completed replaced by CHOL_build_completed

converted ex with curried function application

converted Subst with curried function application

changed syntax of Unity ("()" instead of "<>")

converted IOA with curried function application

changed syntax of "if"

fixed two severe bugs in calc_xrules and case_rule

Corrected a silly old bug in merge_tsigs. Rewrote a lot of Nimmermann's code.

Added a few thms to nat_ss and list_ss

Removed bugs which occurred due to new generation mechanism for type variables

Removed exception handlers, as they are now in ZF/Makefile.

removed print_msg parameter of infer_types

Now mentions Coind

Removed exception handlers, as they are now in ZF/Makefile.

Now calls exit_use instead of use, for prompt failure if errors are detected.

Declares the function exit_use to behave like use but fail if errors are detected. It can be used in all Makefiles except Pure, which will write the exception handler explicitly ("exit" will have been declared already).

Now the "use" call has an exception handler, for prompt failure if errors are detected.

Now calls exit_use instead of use, for prompt failure if errors are detected.

Removed an old bug which made some simultaneous instantiations fail if they were given in the "wrong" order. Rewrote sign/infer_types. Fixed some comments.

added exit 1

Removed superfluous type constraint

Changed treatment of during type inference internally generated type variables. 1. They are renamed to 'a, 'b, 'c etc away from a given set of used names. 2. They are either frozen (turned into TFrees) or left schematic (TVars) depending on a parameter. In goals they are frozen, for instantiations they are left schematic.

Added type constraints to enforce correct choice of variable names.

Put freeze into the signature TACTIC for export

Removed "localize"; instead, proofs refer to their own assumptions.

Commented isof(c,t)

Added dependencies on ../Provers/hypsubst.ML and removed those on ../Provers/ind.ML

Replaced read by read_cterm.

Enforced partial evaluation of mk_case_split_tac.

Enforced partial evaluation of mk_case_split_tac

Added dependencies on files in Provers

Added pretty-printing coments

Hoare logic

Changed Univ to Datatype in parents

Replaced rules by defs. Also got rid of tyconstU by including TyConst in the datatype's universe

Replaced rules by defs

Got rid of exvarU and constU by including ExVar and Const in various datatype universes.

Deleted constQU, exvarQU, expQU by including Const, ExpVar, Exp in Value.thy's codatatype declaration.

Replaced rules by defs

Moved declarations of @QSUM and <*> to a syntax section. Changed print_translation because <*> is now an infix.

Moved declaration of ~= to a syntax section

replaced Pure by ProtoPure

fixed a bug in infer_types/exn_type_msg

new version of HOL/Integ with curried function application

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";
