2010-01-08Numbers: BigN and BigZ get instantiations of all properties about div and modletouzey
NB: for declaring div and mod as a morphism, even when divisor is zero, I've slightly changed the definition of div_eucl: it now starts by a check of whether the divisor is zero. Not very nice, but this way we can say that BigN.div and BigZ.div _always_ answer like Zdiv.Zdiv. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@12646 85f007b7-540e-0410-9357-904b9bb8a0f7

Old stuff DecidableType.v and OrderedType.v stay there and keep their names for the moment, for compatibility. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@12641 85f007b7-540e-0410-9357-904b9bb8a0f7
2010-01-07Include can accept both Module and Module Typeletouzey
Syntax Include Type is still active, but deprecated, and triggers a warning. The syntax M <+ M' <+ M'', which performs internally an Include, also benefits from this: M, M', M'' can be independantly modules or module type. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@12640 85f007b7-540e-0410-9357-904b9bb8a0f7

2010-01-07DecidableType2+OrderedType2 : notations in specific Module Type, slicing of ↵letouzey
OrderedType2 OrderedType2 is reorganized in atomic module type following the same approach used for DecidableType2. We use the following convention: module type Foo' is exactly module type Foo, except that some notations may have been added. In functor arg, we can use Foo or Foo' depending on whether we want nice notation or not. Note that any implementation of Foo is accepted as implementation of Foo' :-). For the moment, these notations are not placed in specific scopes, I think it isn't useful, but I may be wrong, we'll see later when using them. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@12635 85f007b7-540e-0410-9357-904b9bb8a0f7

This used to be convenient in FSets, but since we now try to integrate DecidableType and OrderedType as foundation for other part of the stdlib, this should be avoided, otherwise some eauto take a _long_ time. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@12626 85f007b7-540e-0410-9357-904b9bb8a0f7

2009-12-13Addition of mergesort + cleaning of the Sorting libraryherbelin
- New (modular) mergesort purely using structural recursion - Move of the (complex) notion of permutation up to setoid equality formerly defined in Permutation.v to file PermutSetoid.v - Re-use of the file Permutation.v for making the canonical notion of permutation that was in List.v more visible - New file Sorted.v that contains two definitions of sorted: "Sorted" is a renaming of "sort" that was defined in file Sorting.v and "StronglySorted" is the intuitive notion of sorted (there is also LocallySorted which is a variant of Sorted) - File Sorting.v is replaced by a call to the main Require of the directory - The merge function whose specification rely on counting elements is moved to Heap.v and both are stamped deprecated (the sort defined in Heap.v has complexity n^2 in worst case) - Added some new naming conventions - Removed uselessly-maximal implicit arguments of Forall2 predicate git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@12585 85f007b7-540e-0410-9357-904b9bb8a0f7

This specific syntax is removed, freeing the keyword "Self". Anyway, with the use of the syntax "<+" there was already hardly any need for syntax "Include Self". Idem for Include Type. Beware that a typo such as "Include F" instead of "Include F G" will produce a different message now, about a missing field instead of a not-enough-applied functor. By the way, some code clean-up and factorisation of inner recursive functions in declaremods.ml. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@12566 85f007b7-540e-0410-9357-904b9bb8a0f7

Now that backtracking is working correctly, we need to avoid a non-termination issue introduced by the [RelCompFun] definition in RelationPairs, by adding a [Measure] typeclass.
