2010-02-17Arith's min and max placed in Peano (+basic specs max_l and co)letouzey
This allow for instance to remove the dependency of List.v toward Min.v To prove max_l and co, we push Le.le_pred and Le.le_S_n into Peano. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@12784 85f007b7-540e-0410-9357-904b9bb8a0f7
2009-12-13Addition of mergesort + cleaning of the Sorting libraryherbelin
- New (modular) mergesort purely using structural recursion - Move of the (complex) notion of permutation up to setoid equality formerly defined in Permutation.v to file PermutSetoid.v - Re-use of the file Permutation.v for making the canonical notion of permutation that was in List.v more visible - New file Sorted.v that contains two definitions of sorted: "Sorted" is a renaming of "sort" that was defined in file Sorting.v and "StronglySorted" is the intuitive notion of sorted (there is also LocallySorted which is a variant of Sorted) - File Sorting.v is replaced by a call to the main Require of the directory - The merge function whose specification rely on counting elements is moved to Heap.v and both are stamped deprecated (the sort defined in Heap.v has complexity n^2 in worst case) - Added some new naming conventions - Removed uselessly-maximal implicit arguments of Forall2 predicate git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@12585 85f007b7-540e-0410-9357-904b9bb8a0f7

2009-11-11Improving abbreviations/notations + backtrack of semantic change in r12439herbelin
- Deactivation of short names registration and printing for abbreviations to identical names, what avoids printing uselessly qualified names binding where the short name is in fact equivalent. - New treatment of abbreviations to names: don't insert any maximally inserted implicit arguments at all at the time of the abbreviation and use the regular internalization strategy to have them inserted at use time. - The previous modifications altogether make redirections of qualified names easier and avoid the semantic change of r12349 and hence allows to keep "Notation b := @a" as it was before, i.e. as a notation for the deactivation of the implicit arguments of a. - Took benefit of these changes and updated nil/cons/list/app redefinition in "List.v". - Fixed parsing/printing notation bugs (loop on partially applied abreviations for constructors in constrintern.ml + bad reverting of notations with holes that captured non anonymous variables in match_cases_pattern). - Add support for parsing/printing abbreviations to @-like constructors and for reverting printing for abbreviations to constructors applied to parameters only (function extern_symbol_pattern). - Minor error messages fixes and minor APIs cleaning. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@12494 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

2009-10-19Merge 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
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
