* FSetCompat: a compatibility wrapper between FSets and MSetsGravatar letouzey2009-10-20
| | | | | | | | | | | | Thanks to the functors in FSetCompat, the three implementations of FSets (FSetWeakList, FSetList, FSetAVL) are just made of a few lines adapting the corresponding MSets implementation to the old interface. This approach breaks FSetFullAVL. Since this file is of little use for stdlib users, we migrate it into contrib Orsay/FSets. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@12402 85f007b7-540e-0410-9357-904b9bb8a0f7

* Merge SetoidList2 into SetoidList.Gravatar letouzey2009-10-19
| | | | | | | | | 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
* OrderedType2 : trivial lemmas are turned into tests for order.Gravatar letouzey2009-10-16
| | | | | | | In particular we remove them from the hint db, a few autos become calls to order. Moreover, lt_antirefl --> lt_irrefl for uniformity. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@12398 85f007b7-540e-0410-9357-904b9bb8a0f7
* Structure/OrderTac.v : highlight the "order" tactic by isolating it from ↵Gravatar letouzey2009-10-16
| | | | | | | | | | | | | | FSets, and improve it As soon as you have a eq, a lt and a le (that may be lt\/eq, or (complement (flip (lt))) and a few basic properties over them, you can instantiate functor MakeOrderTac and gain an "order" tactic. See comments in the file for the scope of this tactic. NB: order doesn't call auto anymore. It only searches for a contradiction in the current set of (in)equalities (after the goal was optionally turned into hyp by double negation). Thanks to S. Lescuyer for his suggestions about this tactic. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@12397 85f007b7-540e-0410-9357-904b9bb8a0f7

* Improved tactic "order" in OrderedTypeGravatar letouzey2009-10-14
| | | | | | | | | | | | | | | | | | | I forgot to mention in last commit message about MSets that the corresponding OrderedType2 comes with a redesigned "order" tactic. It should now be complete for its purpose (that is solve systems of (in)equations of variables over == < <= <>). Non-linear matching is cool, I love Ltac :-). Unlike the old "order", this new version is meant to completely solve the goal or fail. Speed might be an issue for big systems, but in pratice it is quite efficient on the examples encountered in FSets. This commit: - propagages this new "order" to the original OrderedType.v file used for the old FSet. - fixes a bug : the ltac loop shouldn't fail otherwise strange backtrack occurs. I hate Ltac :-( git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@12388 85f007b7-540e-0410-9357-904b9bb8a0f7

* MSets: a new generation of FSetsGravatar letouzey2009-10-13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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

* Fix the stdlib doc compilation + switch all .v file to utf8Gravatar letouzey2009-09-28
| | | | | | | | | | | | | | | | | | | 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
