2010-02-17RelationClasses: adapt eq_Reflexive and co to avoid Universe Inconsistenciesletouzey
We explicitely take care of the argument A to be given to eq_refl,sym,trans when proving that Logic.eq is an instance of Equivalence. This should solve the recent Universe Inconsistencies encountered in CoLoR and FingerTree. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@12786 85f007b7-540e-0410-9357-904b9bb8a0f7

2009-11-30Fix backtracking heuristic in typeclass resolution. msozeau
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. It could be used to have a uniform notation for measures/interpretations in Numbers and be but in the interfaces too, only the mimimal change was implemented.

2009-11-06Numbers: finish files NStrongRec and NDefOpsletouzey
- NStrongRec provides a "strong" recursor based on the usual one: recursive calls can be done here on any lower value. See binary log in NDefOps for an example of use. - NDefOps contains alternative definitions of usual operators (add, mul, ltb, pow, even, half, log) via usual or strong recursor, and proofs of correctness and/or of equivalence with axiomatized operators. These files were in the archive but not being compiled, some proofs of correction for functions defined there were missing. By the way, some more iff-style lemmas in Bool. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@12476 85f007b7-540e-0410-9357-904b9bb8a0f7
2009-11-03OrderedType implementation for various numerical datatypes + min/max structuresletouzey
- A richer OrderedTypeFull interface : OrderedType + predicate "le" - Implementations {Nat,N,P,Z,Q}OrderedType.v, also providing "order" tactics - By the way: as suggested by S. Lescuyer, specification of compare is now inductive - GenericMinMax: axiomatisation + properties of min and max out of OrderedTypeFull structures. - MinMax.v, {Z,P,N,Q}minmax.v are specialization of GenericMinMax, with also some domain-specific results, and compatibility layer with already existing results. - Some ML code of plugins had to be adapted, otherwise wrong "eq", "lt" or simimlar constants were found by functions like coq_constant. - Beware of the aliasing problems: for instance eq:=@eq t instead of eq:=@eq M.t in Make_UDT made (r)omega stopped working (Z_as_OT.t instead of Z in statement of Zmax_spec). - Some Morphism declaration are now ambiguous: switch to new syntax anyway. - Misc adaptations of FSets/MSets - Classes/RelationPairs.v: from two relations over A and B, we inspect relations over A*B and their properties in terms of classes. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@12461 85f007b7-540e-0410-9357-904b9bb8a0f7

2009-11-02list, length, app are migrated from List to Datatypesletouzey
This allows easier handling of dependencies, for instance RelationClasses won't have to requires List (which itself requires part of Arith, etc). One of the underlying ideas is to provide setoid rewriting in Init someday. Thanks to some notations in List, this change should be fairly transparent to the user. For instance, one could see that List.length is a notation for (Datatypes.)length only when doing a Print List.length. For these notations not to be too intrusive, they are hidden behind an explicit Export of Datatypes at the end of List. This isn't very pretty, but quite handy. Notation.ml is patched to stop complaining in the case of reloading the same Delimit Scope twice. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@12452 85f007b7-540e-0410-9357-904b9bb8a0f7
2009-10-27Add a new vernacular command for controling implicit generalization ofmsozeau
variables with syntax: [Local?|Global] Generalizable Variable(s)? [all|none|id1 idn]. By default no variable is generalizable, so this patch breaks backward compatibility with files that used implicit generalization (through Instance declarations for example). To get back the old behavior, one just needs to use [Global Generalizable Variables all]. Make coq_makefile more robust using [mkdir -p]. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@12428 85f007b7-540e-0410-9357-904b9bb8a0f7
2009-10-22Fix new instances that could easily make class resolution loop on msozeau
unconstrained goals (e.g. PreOrder A ?). Allow the unconstrained use of [proper_reflexive] again. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@12407 85f007b7-540e-0410-9357-904b9bb8a0f7
2009-10-13MSets: a new generation of FSetsletouzey
Same global ideas (in particular the use of modules/functors), but: - frequent use of Type Classes inside interfaces/implementation. For instance, no more eq_refl/eq_sym/eq_trans, but Equivalence. A class StrictOrder for lt in OrderedType. Extensive use of Proper and rewrite. - now that rewrite is mature, we write specifications of set operators via iff instead of many separate requirements based on ->. For instance add_spec : In y (add x s) <-> E.eq y x \/ In x s. Old-style specs are available in the functor Facts. - compare is now a pure function (t -> t -> comparison) instead of returning a dependent type Compare. - The "Raw" functors (the ones dealing with e.g. list with no sortedness proofs yet, but morally sorted when operating on them) are given proper interfaces and a generic functor allows to obtain a regular set implementation out of a "raw" one. The last two points allow to manipulate set objects that are completely free of proof-parts if one wants to. Later proofs will rely on type-classes instance search mechanism. No need to emphasis the fact that this new version is severely incompatible with the earlier one. I've no precise ideas yet on how allowing an easy transition (functors ?). For the moment, these new Sets are placed alongside the old ones, in directory MSets (M for Modular, to constrast with forthcoming CSets, see below). A few files exist currently in version foo.v and foo2.v, I'll try to merge them without breaking things. Old FSets will probably move to a contrib later. Still to be done: - adapt FMap in the same way - integrate misc stuff like multisets or the map function - CSets, i.e. Sets based on Type Classes : Integration of code contributed by S. Lescuyer is on the way. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@12384 85f007b7-540e-0410-9357-904b9bb8a0f7

2009-09-28Fix the stdlib doc compilation + switch all .v file to utf8letouzey
1) compilation of Library.tex was failing on a "Ext_" in Diaconescu.v In fact coqdoc was trying to recognize the end of a _emphasis_ and hence inserted a bogus }. For the moment I've enclosed the phrase with [ ], but this emphasis "feature" of coqdoc seems _really_ easy to broke. Matthieu ? 2) By the way, this Library document was made from latin1 and utf8 source file, hence bogus characters. All .v containing special characters are converted to utf8, and their first line is now mentionning this. (+ killed some old french comments and some other avoidable special characters). PLEASE: let's stick to this convention and avoid latin1, at least in .v files. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@12363 85f007b7-540e-0410-9357-904b9bb8a0f7

2009-09-08Fix the bug-ridden code used to choose leibniz or generalizedmsozeau
rewriting (thanks to Georges Gonthier for pointing it out). We try to find a declared rewrite relation when the equation does not look like an equality and otherwise try to reduce it to find a leibniz equality but don't backtrack on generalized rewriting if this fails. This new behavior make two fsets scripts fail as they are trying to use an underlying leibniz equality for a declared rewrite relation, a [red] fixes it. Do some renaming from "setoid" to "rewrite".

2009-03-28Rewrite of Program Fixpoint to overcome the previous limitations: msozeau
- The measure can now refer to all the formal arguments - The recursive calls can make all the arguments vary as well - Generalized to any relation and measure (new syntax {measure m on R}) This relies on an automatic curryfication transformation, the real fixpoint combinator is working on a sigma type of the arguments. Reduces to the previous impl in case only one argument is involved. The patch also introduces a new flag on implicit arguments that says if the argument has to be infered (default) or can be turned into a subgoal/obligation.

2008-12-14Generalized binding syntax overhaul: only two new binders: `() and `{},msozeau
guessing the binding name by default and making all generalized variables implicit. At the same time, continue refactoring of Record/Class/Inductive etc.., getting rid of [VernacRecord] definitively. The AST is not completely satisfying, but leaning towards Record/Class as restrictions of inductive (Arnaud, anyone ?). Now, [Class] declaration bodies are either of the form [meth : type] or [{ meth : type ; ... }], distinguishing singleton "definitional" classes and inductive classes based on records. The constructor syntax is accepted ([meth1 : type1 | meth1 : type2]) but raises an error immediately, as support for defining a class by a general inductive type is not there yet (this is a bugfix!). git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@11679 85f007b7-540e-0410-9357-904b9bb8a0f7
