2008-07-04Fixes in handling of implicit arguments:msozeau
- Now [ id : Class foo ] makes id an explicit argument, and [ Class foo ] is equivalent to [ {someid} : Class foo ]. This makes declarations such as "Class Ord [ eq : Eq a ]" have sensible implicit args. - Better handling of {} in class and record declarations, refactorize code for declaring structures and classes. - Fix merging of implicit arguments information on section closing. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@11204 85f007b7-540e-0410-9357-904b9bb8a0f7
2008-06-21Code cleanup in typeclasses, remove dead and duplicated code.msozeau

2008-05-06Better parsing of typeclasses, any constr is allowed for ! bindings somsozeau
notations work and bug #1846 gets completely fixed. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@10890 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

2008-04-01Enhance handling of parameters in typeclass constraints: permit to specify ↵msozeau
any typeclass parameter by name anywhere in a typeclass constraint. This allows to share implementations easily and to give any subset of the parameters in any order in the constraints, whereas we are still restricted to a prefix of the typeclass parameters context when using "positional" specifications. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@10736 85f007b7-540e-0410-9357-904b9bb8a0f7
2008-03-31- Fix for rewriting under dependent products.msozeau
- Use support for abbreviations with params added by Hugo for inverse. - Standard priorities for operators on relations. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@10733 85f007b7-540e-0410-9357-904b9bb8a0f7

Example: "Notation reflexive R := (forall x, R x x)." git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@10730 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
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

2008-01-15Generalize instance declarations to any context, better name handling. Add ↵msozeau
hole kind info for topconstrs. Derive eta_expansion from functional extensionality axiom. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@10439 85f007b7-540e-0410-9357-904b9bb8a0f7
2008-01-07Cleaner quantifiers for type classes, breaks clrewrite for the moment but ↵msozeau
implementation is much less add-hoc. Opens possibility of arbitrary prefixes in Class and Instance declarations. Current implementation with eauto is a bit more dangerous... next patch will fix it. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@10432 85f007b7-540e-0410-9357-904b9bb8a0f7
2008-01-05Fix a naming bug reported by Arnaud Spiwack, allow instance search to create ↵msozeau
evars and try to solve them too. Finally, rework tactics on setoids and design a saturating tactic to help solve goals on any setoid. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@10428 85f007b7-540e-0410-9357-904b9bb8a0f7
