merged

quotient types registered as codatatypes are no longer quotient types

added a friendly warning

extend the scope of limitation about nonconservative extensions

improved "merge_type_vars" option: map supersorts to subsorts, to avoid distinguishing, say, "{}", and "HOL.type"

Remove duplicate locale activation code; performance improvement.

added record field

added "whack"

handle "Rep_unit" & Co. gracefully

added support for "Abs_" and "Rep_" functions on quotient types

fiddle with specialization etc.

handle inductive predicates correctly after change in "def" semantics

don't specialize built-ins or constructors

more docs

prevent the expansion of too large definitions -- use equations for these instead

make nitpick accept "==" for "nitpick_(p)simp"s

fix bug in Nitpick's "equationalize" function (the prems were ignored) + make it do some basic extensionalization

deal correctly with Pure.conjunction in mono check

rename internal functions

remove buggy and needless condition

renamed internal function

Cycle breaking in the bounds takes care of singly recursive datatypes, so we don't need to do it again; the effect of removing the constraint varies on problem to problem, but it tends to be overwhelmingly negative in conjuction with the new datatype sym breaking stuff at high cardinalities

avoid "<=>" in sym break constraint generation (since these are SAT-unfreundlich) + fix "epsilon2" to "epsilon1" (subtle bug)

improve datatype symmetry breaking; all based on "datatype bin_list = BNil | B0Cons bin_list | B1Cons bin_list" example

merged

make SML/NJ happy

get rid of all "optimizations" regarding "unit" and other cardinality-1 types

tuning

better "Pretty" handling

change formula for enumerating scopes

example tweaking -- also prevents Nitpick_Tests from using more than 1 thread

speed up Nitpick examples a little bit

minor changes

updated example timings

more helpful message

also mention gfp

bump up the max cardinalities, to use up more of the time given to us by the user

make tracing monotonicity easier

more documentation, based on email discussions with a user

make example easier to parse

clarify attribute documentation

choose better example

fix newly introduced bug w.r.t. conditional equations

document something I explained in an email to a poweruser

make Nitpick more flexible when parsing (p)simp rules

fix soundness bug w.r.t. "Suc" with "binary_ints"

handle free variables even more gracefully; 1. show those that only occur in assumptions as part of the constants; 2. make sure locally defined Frees are given an Opt rep, just like constants generally owuld

optimize local "def"s by treating them as definitions

careful about which linear inductive predicates should be starred

help Nitpick

fix Skolemizer -- last week's optimizations resulted in UnequalLengths errors

prevent generation of needless specialized constants etc.

optimize generated Kodkod formula

prefer implication to equality, to be more SAT solver friendly

minor symmetry breaking for codatatypes like llist

fix bug with mutually recursive and nested codatatypes

fix minor bug in sym breaking
