2008-04-16Definition of N moves back to BinNat (partial backtrack of commits 10298-10300)letouzey
This way, no more references to NBinDefs.N when doing "Print N". Long-term migration to theories/Numbers is still planned, but it needs more works, for instance to adapt both positive and N and Z at once. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@10806 85f007b7-540e-0410-9357-904b9bb8a0f7

2008-04-15- Add "Global" modifier for instances inside sections with the usualmsozeau
semantics. - Add an Equivalence instance for pointwise equality from an Equivalence on the codomain of a function type, used by default when comparing functions with the Setoid's ===/equiv. - Partially fix the auto hint database "add" function where the exact same lemma could be added twice (happens when doing load for example). git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@10797 85f007b7-540e-0410-9357-904b9bb8a0f7

2008-04-12Add the ability to specify what to do with free variables in instancemsozeau
declarations. By default, print the list of implicitely generalized variables. Implement new commands Add Parametric Relation/Morphism for... parametric relations and morphisms. Now the Add * commands are strict about free vars and will fail if there remain some. Parametric just allows to give a variable context. Also, correct a bug in generalization of implicits that ordered the variables in the wrong order. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@10782 85f007b7-540e-0410-9357-904b9bb8a0f7

- Use a notation for predicate instead of a definition (better pretty-printing this way, and no delta problem!). - Correct inadvertent import of Coq.Program.Program which sets implicit arguments for left,right and so on.

2008-04-08- A little cleanup in Classes/*. Separate standard morphisms onmsozeau
relf/sym/trans relations from morphisms on prop connectives and relations. - Add general order theory on predicates, instantiated for relations. Derives equivalence, implication, conjunction and disjunction as liftings from propositional connectives. Can be used for n-ary homogeneous predicates thanks to a bit of metaprogramming with lists of types. - Rebind Setoid_Theory to use the Equivalence record type instead of declaring an isomorphic one. One needs to do "red" after constructor to get the same statements when building objects of type Setoid_Theory, so scripts break. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@10765 85f007b7-540e-0410-9357-904b9bb8a0f7
2008-04-06Renoncement à rationaliser les Hints "real" vis à vis de Rle/Rge et Rlt/Rgt :herbelin
- si on met Rle_ge et Rge_le tous les deux en Resolve (et de même pour Rlt_gt et Rgt_lt) alors on introduit un cycle, - si on en met un des deux en Immediate, alors on perd la symétrie car si un développement n'a un lemme en hints que pour Rge (resp Rle), alors il ne sera pas utilisable si on met Rge_le (resp Rle_ge) en Immediate (et c'est ce qui arrive notamment dans HighSchoolGeometry). L'idéal serait d'introduire une notion de raisonnement modulo équivalence dans auto afin que chaque lemme sur Rle (resp Rge) soit systématiquement applicable aussi face à Rge (resp Rle) sans redondances et sans cycle. Ainsi Rle_ge and co n'auraient pas un statut de hints mais plutôt un statut de conversions implicites entre notions synonymes. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@10762 85f007b7-540e-0410-9357-904b9bb8a0f7

2008-04-03New file FMapFullAVL containing the balancing proofs about FMapAVL:letouzey
As for FSetAVL vs. FSetFullAVL, preservation of the balancing of trees is not necessary anymore for just fulfilling the Map interface. But we still want theses proofs to exists somewhere, since they ensure the correct efficiency of the FMapAVL operations. In addition, FSetFullAVL also contains the non-structural, ocaml-faithful version of compare. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@10748 85f007b7-540e-0410-9357-904b9bb8a0f7
2008-04-03Rework of FMapAVL inspired by recent changes of FSetAVL: letouzey
* pure functions comes first, proofs are isolated in a sub-module * lazy (&&&) = if ... then ... else true instead of strict (&&) = andb * equal and compare done via continuations * a more clever map2_opt suggested by B. Gregoire: no more intermediate conversion to lists, some sub-functions can handle trivial situations, etc. * map2 is now done via map2_opt and another new iterator: map_option. By the way, this map_option allows to define easily an efficient filter function. Both map2_opt and map_option are currently not available through FMapInterface.S, but they can be used by direct reference to the underlying Raw module. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@10745 85f007b7-540e-0410-9357-904b9bb8a0f7

2008-03-28Improve error handling and messages for typeclasses. msozeau
Add definitions of relational algebra in Classes/RelationClasses including equivalence, inclusion, conjunction and disjunction. Add PartialOrder class and show that we have a partial order on relations. Change SubRelation to subrelation for consistency with the standard library. The caracterization of PartialOrder is a bit original: we require an equivalence and a preorder so that the equivalence relation is equivalent to the conjunction of the order relation and its inverse. We can derive antisymmetry and appropriate morphism instances from this. Also add a fully general heterogeneous definition of respectful from which we can build the non-dependent respectful combinator. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@10728 85f007b7-540e-0410-9357-904b9bb8a0f7
2008-03-28- Second pass on implementation of let pattern. Parse "let ' par [as x]?msozeau
[in I] := t [return pred] in b", just as SSReflect does with let:. Change implementation: no longer a separate AST node, just add a case_style annotation on Cases to indicate it (if ML was dependently typed we could ensure that LetPatternStyle Cases have only one term to be matched and one branch, alas...). This factors out most code and we lose no functionality (win ! win !). Add LetPat.v test suite. - Slight improvement of inference of return clauses for dependent pattern matching. If matching a variable of non-dependent type under a tycon that mentions it while giving no return clause, the dependency will be automatically infered. Examples at the end of DepPat. Should get rid of most explicit returns under tycons. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@10727 85f007b7-540e-0410-9357-904b9bb8a0f7

2008-03-27Various fixes on typeclasses:msozeau
- Better interface in constrintern w.r.t. evars used during typechecking - Add "unsatisfiable_constraints" exception which gives back the raw evar_map that was not satisfied during typeclass search (presentation could be improved). - Correctly infer the minimal sort for typeclasses declared as definitions (everything was in type before). - Really handle priorities in typeclass eauto: goals produced with higher priority (lowest number) instances are tried before other of lower priority goals, regardless of the number of subgoals. - Change inverse to a notation for flip, now that universe polymorphic definitions are handled correctly. - Add EquivalenceDec class similar to SetoidDec, declaring decision procedures for equivalences. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@10724 85f007b7-540e-0410-9357-904b9bb8a0f7

2008-03-23Fix a bug found by B. Grégoire when declaring morphisms in modulemsozeau
types. Change (again) the semantics of bindings and the binding modifier ! in typeclasses. Inside [ ], implicit binding where only parameters need to be given is the default, use ! to use explicit binding, which is equivalent to regular bindings except for generalization of free variables. Outside brackets (e.g. on the right of instance declarations), explicit binding is the default, and implicit binding can be used by adding ! in front. This avoids almost every use of ! in the standard library and in other examples I have. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@10713 85f007b7-540e-0410-9357-904b9bb8a0f7

symmetric... classes for now, merging Relations with RelationClasses requires some non-trivial changes on implicits but also some definitions are different (e.g. antisymmetric in Classes is defined w.r.t an equivalence relation and not eq). Move back to Reflexive and so on. reflexivity-like tactics fail in the same way as before if Setoid was not imported.

2008-03-19Do another pass on the typeclasses code. Correct globalization of classmsozeau
names, gives the ability to specify qualified classes in instance declarations. Use that in the class_tactics code. Refine the implementation of classes. For singleton classes the implementation of the class becomes a regular definition (into Type or Prop). The single method becomes a 'trivial' projection that allows to launch typeclass resolution. Each instance is just a definition as usual. Examples in theories/Classes/RelationClasses. This permits to define [Class reflexive A (R : relation A) := refl : forall x, R x x.]. The definition of [reflexive] that is generated is the same as the original one. We just need a way to declare arbitrary lemmas as instances of a particular class to retrofit existing reflexivity lemmas as typeclass instances of the [reflexive] class. Also debug rewriting under binders in setoid_rewrite to allow rewriting with lemmas which capture the bound variables when applied (works only with setoid_rewrite, as rewrite first matches the lemma with the entire, closed term). One can rewrite with [H : forall x, R (f x) (g x)] in the goal [exists x, P (f x)]. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@10697 85f007b7-540e-0410-9357-904b9bb8a0f7

2008-03-17Add the possibility of specifying constants to unfold for typeclassmsozeau
resolution. Add [relation] and Setoid's [equiv] as such objects. Considerably simplify resolve_all_evars for typeclass resolution, adding a further refinement (and hack): evars get classified as non-resolvable (using the evar_extra dynamic field) if they are turned into a goal. This makes it possible to perform nested typeclass resolution without looping. We take advantage of that in Classes/Morphisms where [subrelation_tac] is added to the [Morphism] search procedure and calls the apply tactic which itself triggers typeclass resolution. Having [subrelation_tac] as a tactic instead of an instance, we can actually force that it is applied only once in each search branch and avoid looping. We could get rid of the hack when we have real goals-as-evars functionality (hint hint). Also fix some test-suite scripts which were still calling [refl] instead of [reflexivity]. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@10687 85f007b7-540e-0410-9357-904b9bb8a0f7
