2008-03-16Reorganize Program and Classes theories. Requiring Setoid no longer setsmsozeau
implicits for left, inl or eq, hence some theories had to be changed again. It should make some user contribs compile again too. Also do not import functional extensionality when importing Program.Basics, add a Combinators file for proofs requiring it and a Syntax file for the implicit settings. Move Classes.Relations to Classes.RelationClasses to avoid name clash warnings as advised by Hugo and Pierre. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@10681 85f007b7-540e-0410-9357-904b9bb8a0f7
2008-03-16Minor fixes on setoid rewriting. Now uses definitions of [relation] andmsozeau
[id] instead of their expansions. Seems to slow things down a bit (1s. on Ring_polynom). git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@10680 85f007b7-540e-0410-9357-904b9bb8a0f7
2008-03-08Fix bugs that were reopened due to the change of setoidmsozeau
implementation. Mostly syntax changes when declaring parametric relations, but also some declarations were relying on "default" relations on some carrier. Added a new DefaultRelation type class that allows to do that, falling back to the last declared Equivalence relation by default. This will be bound to Add Relation in the next commit. Also, move the "left" and "right" notations in Program.Utils to "in_left" and "in_right" to avoid clashes with existing scripts. Minor change to record to allow choosing the name of the argument for the record in projections to avoid possible incompatibilities. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@10639 85f007b7-540e-0410-9357-904b9bb8a0f7
2008-03-06Syntax changes in typeclasses, remove "?" for usual implicit argumentsmsozeau
binding, add "!" syntax for the new binders which require parameters and not superclasses. Change backquotes for curly braces for user-given implicit arguments, following tradition. This requires a hack a la lpar-id-coloneq. Change ident to global for typeclass names in class binders. Also requires a similar hack to distinguish between [ C t1 tn ] and [ c : C t1 tn ]. Update affected theories. While hacking the parsing of { wf }, factorized the two versions of fix annotation parsing that were present in g_constr and g_vernac. Add the possibility of the user optionaly giving the priority for resolve and exact hints (used by type classes). Syntax not fixed yet: a natural after the list of lemmas in "Hint Resolve" syntax, a natural after a "|" after the instance constraint in Instance declarations (ex in Morphisms.v). git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@10628 85f007b7-540e-0410-9357-904b9bb8a0f7
2008-02-28Do not open type_scope in SetoidClass.msozeau

2008-02-26Proper implicit arguments handling for assumptionsmsozeau
(Axiom/Variable...). New tactic clapply to apply unapplied class methods in tactic mode, simple solution to the fact that apply does not work up-to classes yet. Add Functions.v for class definitions related to functional morphisms. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@10589 85f007b7-540e-0410-9357-904b9bb8a0f7
2008-02-13Debugging of the class_setoid tactic and eauto. Prepare for move frommsozeau
class_setoid to class_tactics... git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@10563 85f007b7-540e-0410-9357-904b9bb8a0f7
2008-02-09Fix the clrewrite tactic, change Relations.v to work on relations in Propmsozeau
only, and get rid of the "relation" definition which makes unification fail blatantly. Replace it with a notation :) In its current state, the new tactic seems ready for larger tests. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@10543 85f007b7-540e-0410-9357-904b9bb8a0f7
2008-02-08Change implementation of resolution for typeclasses to use a customizedmsozeau
eauto instead of an arbitrary tactic. Export more from eauto to allow easier debugging. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@10534 85f007b7-540e-0410-9357-904b9bb8a0f7
2008-02-06New algorithm to resolve morphisms, after discussion with Nicolasmsozeau
Tabareau: - first pass: generation of the Morphism constraints with metavariables for unspecified relations by one fold over the term. This builds a "respect" proof term for the whole term with holes. - second pass: constraint solving of the evars, taking care of finding a solution for all the evars at once. - third step: normalize proof term by found evars, apply it, done! Works with any relation, currently not as efficient as it could be due to bad handling of evars. Also needs some fine tuning of the instances declared in Morphisms.v that are used during proof search, e.g. using priorities. Reorganize Classes.* accordingly, separating the setoids in Classes.SetoidClass from the general morphisms in Classes.Morphisms and the generally applicable relation theory in Classes.Relations. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@10515 85f007b7-540e-0410-9357-904b9bb8a0f7
2008-02-03Add new files theories/Program/Basics.v and theories/Classes/Relations.vmsozeau
for basic functional programming and relation definitions respectively. Classes.Relations also includes the definition of Morphism and instances for the standard morphisms and relations (eq, iff, impl, inverse and complement). The class_setoid.ml4 [setoid_rewrite] tactic has been reimplemented on top of these definitions, hence it doesn't require a setoid implementation anymore. It also generates obligations for missing reflexivity proofs, like the current setoid_rewrite. It has not been tested on large examples but it should handle directions and occurences. Works with in if no obligations are generated at this time. What's missing is being able to rewrite by a lemma instead of a simple hypothesis with no premises. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@10502 85f007b7-540e-0410-9357-904b9bb8a0f7
