2012-07-05ZArith + other : favor the use of modern names instead of compat notationsletouzey
- For instance, refl_equal --> eq_refl - Npos, Zpos, Zneg now admit more uniform qualified aliases N.pos, Z.pos, Z.neg. - A new module BinInt.Pos2Z with results about injections from positive to Z - A result about Z.pow pushed in the generic layer - Zmult_le_compat_{r,l} --> Z.mul_le_mono_nonneg_{r,l} - Using tactic Z.le_elim instead of Zle_lt_or_eq - Some cleanup in ring, field, micromega (use of "Equivalence", "Proper" ...) - Some adaptions in QArith (for instance changed Qpower.Qpower_decomp) - In ZMake and ZMake, functor parameters are now named NN and ZZ instead of N and Z for avoiding confusions git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@15515 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
2009-10-19Merge SetoidList2 into SetoidList.letouzey
This file contains low-level stuff for FSets/FMaps. Switching it to the new version (the one using Equivalence and so on instead of eq_refl/eq_sym/eq_trans and so on) only leads to a few changes in FSets/FMaps that are minor and probably invisible to standard users. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@12400 85f007b7-540e-0410-9357-904b9bb8a0f7

2008-12-26FMaps: various updates (mostly suggested by P. Casteran)letouzey
- New functions: update (a kind of union), restrict (a kind of inter), diff. - New predicat Partition (and Disjoint), many results about Partition. - Equivalence instead of obsolete Setoid_Theory (they are aliases). refl_st, sym_st, trans_st aren't used anymore and marked as obsolete. - Start using Morphism (E.eq==>...) instead of compat_... This change (FMaps only) is incompatible with 8.2betaX, but it's really better now. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@11718 85f007b7-540e-0410-9357-904b9bb8a0f7

2008-12-17FSet/OrderedType now includes an eq_dec, and hence become an extension of ↵letouzey
DecidableType After lots of hesitations, OrderedType now requires this "eq_dec" field, which is redundant (can be deduced from "compare"), but allows the subtyping relation DecidableType <= OrderedType, and hence WS <= S : ordered sets are now truly extensions of weak sets. Of course this change introduces a last-minute incompatibility, but: - There is a clear gain in term of functionnality / simplicity. - FSets 8.2 already needs some adaptations when compared with 8.1, so it's the right time to push such incompatible changes. - Transition shouldn't be too hard: the old OrderedType still exists under the name MiniOrderedType, and functor MOT_to_OT allows to convert from one to the other. Beware, for a FSetInterface.WS (resp. S) to be coercible to a DecidableType (resp. OrderedType), an eq_dec on sets is now required in these interfaces and in the implementations. In pratice, it is really easy to build from equal and equal_1 and equal_2. Some name changes : in FSetFacts, old WFacts now correspond to WFacts_fun, while WFacts now expects only one argument (WFacts M := WFacts_fun M.E M). Idem with WDecide, WProperties and WEqProperties. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@11693 85f007b7-540e-0410-9357-904b9bb8a0f7
2008-09-14Add user syntax for creating hint databases [Create HintDb foomsozeau
[discriminated]] with a switch for using the more experimantal dnet impl for every hint. Also add [Hint Transparent/Opaque] which parameterize the dnet and the unification flags used by auto/eauto with a particular database. Document all this. Remove [Typeclasses unfold] directives that are no longer needed (everything is unfoldable by default) and move to [Typeclasses Transparent/Opaque] syntax. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@11409 85f007b7-540e-0410-9357-904b9bb8a0f7
2008-06-27Enhanced discrimination nets implementation, which can now work withmsozeau
goals containing existentials and use transparency information on constants (optionally). Only used by the typeclasses eauto engine for now, but could be used for other hint bases easily (just switch a boolean). Had to add a new "creation" hint to be able to set said boolean upon creation of the typeclass_instances hint db. Improve the proof-search algorithm for Morphism, up to 10 seconds gained in e.g. Field_theory, Ring_polynom. Added a morphism declaration for [compose]. One needs to declare more constants as being unfoldable using the [Typeclasses unfold] command so that discrimination is done correctly, but that amounts to only 6 declarations in the standard library. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@11184 85f007b7-540e-0410-9357-904b9bb8a0f7
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
2008-03-19Do 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
2008-03-06Plug the new setoid implemtation in, leaving the original one commentedmsozeau
out. The semantics of the old setoid are faithfully simulated by the new tactic, hence no scripts involving rewrite are modified. However, parametric morphism declarations need to be changed, but there are only a few in the standard library, notably in FSets. The declaration and the introduction of variables in the script need to be tweaked a bit, otherwise the proofs remain unchanged. Some fragile scripts not introducting their variable names explicitely were broken. Requiring Setoid requires Program.Basics which sets stronger implicit arguments on some constants, a few scripts benefit from that. Ring/field have been ported but do not really use the new typeclass architecture as well as they could. Performance should be mostly unchanged, but will certainly improve in the near future. Size of the vo's seems not to have changed at all. It will certainly break some contribs using Setoid. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@10631 85f007b7-540e-0410-9357-904b9bb8a0f7

2008-02-04Reorganization of FSet+FMap : no more files specific to Weak Sets/Mapsletouzey
Thanks to Elie's work and especially "Include Type ...", full sets can be simply expressed as extensions of weak sets. Moreover, Facts and Properties functors can be factorized almost completely. As a result, things like FSetWeakAAA.BBB can now be found as FSetAAA.WBBB, Same with maps / weak maps ... No backward compatibility intended for weak sets / maps, but porting scripts should mostly amounts to name changes (see above). git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@10505 85f007b7-540e-0410-9357-904b9bb8a0f7

2007-10-29Revision of the FSetWeak Interface, so that it becomes a precise letouzey
subtype of the FSet Interface (and idem for FMapWeak / FMap). 1) No eq_dec is officially required in FSetWeakInterface.S.E (EqualityType instead of DecidableType). But of course, implementations still needs this eq_dec. 2) elements_3 differs in FSet and FSetWeak (sort vs. nodup). In FSetWeak we rename it into elements_3w, whereas in FSet we artificially add elements_3w along to the original elements_3. Initial steps toward factorization of FSetFacts and FSetWeakFacts, and so on... Even if it's not required, FSetWeakList provides a eq_dec on sets, allowing weak sets of weak sets. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@10271 85f007b7-540e-0410-9357-904b9bb8a0f7
