2008-12-17FSet/OrderedType now includes an eq_dec, and hence become an extension of ↵letouzey
DecidableType After lots of hesitations, OrderedType now requires this "eq_dec" field, which is redundant (can be deduced from "compare"), but allows the subtyping relation DecidableType <= OrderedType, and hence WS <= S : ordered sets are now truly extensions of weak sets. Of course this change introduces a last-minute incompatibility, but: - There is a clear gain in term of functionnality / simplicity. - FSets 8.2 already needs some adaptations when compared with 8.1, so it's the right time to push such incompatible changes. - Transition shouldn't be too hard: the old OrderedType still exists under the name MiniOrderedType, and functor MOT_to_OT allows to convert from one to the other. Beware, for a FSetInterface.WS (resp. S) to be coercible to a DecidableType (resp. OrderedType), an eq_dec on sets is now required in these interfaces and in the implementations. In pratice, it is really easy to build from equal and equal_1 and equal_2. Some name changes : in FSetFacts, old WFacts now correspond to WFacts_fun, while WFacts now expects only one argument (WFacts M := WFacts_fun M.E M). Idem with WDecide, WProperties and WEqProperties. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@11693 85f007b7-540e-0410-9357-904b9bb8a0f7
2008-12-11Structural definition of PositiveMap.foldglondu
This definition makes it usable in fixpoints over inductive types based on PositiveMap.t . git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@11668 85f007b7-540e-0410-9357-904b9bb8a0f7

With the previous definition, it was e.g. impossible to define a fixpoint for the inductive type: Inductive t : Set := T : PositiveMap.t t -> t. using PositiveMap.map. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@11664 85f007b7-540e-0410-9357-904b9bb8a0f7

- clarifications about Equality on maps Caveat: name change, what used to be Equal is now Equivb - the prefered equality predicate (the new Equal) is declared a setoid equality, along with several morphisms - beginning of a filter/for_all/exists_/partition section in FMapFacts git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@10608 85f007b7-540e-0410-9357-904b9bb8a0f7

2007-10-29Revision of the FSetWeak Interface, so that it becomes a precise letouzey
subtype of the FSet Interface (and idem for FMapWeak / FMap). 1) No eq_dec is officially required in FSetWeakInterface.S.E (EqualityType instead of DecidableType). But of course, implementations still needs this eq_dec. 2) elements_3 differs in FSet and FSetWeak (sort vs. nodup). In FSetWeak we rename it into elements_3w, whereas in FSet we artificially add elements_3w along to the original elements_3. Initial steps toward factorization of FSetFacts and FSetWeakFacts, and so on... Even if it's not required, FSetWeakList provides a eq_dec on sets, allowing weak sets of weak sets. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@10271 85f007b7-540e-0410-9357-904b9bb8a0f7
