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
2009-10-16Structure/OrderTac.v : highlight the "order" tactic by isolating it from ↵letouzey
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
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

2008-04-03New file FMapFullAVL containing the balancing proofs about FMapAVL:letouzey
As for FSetAVL vs. FSetFullAVL, preservation of the balancing of trees is not necessary anymore for just fulfilling the Map interface. But we still want theses proofs to exists somewhere, since they ensure the correct efficiency of the FMapAVL operations. In addition, FSetFullAVL also contains the non-structural, ocaml-faithful version of compare. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@10748 85f007b7-540e-0410-9357-904b9bb8a0f7
2008-04-03Rework of FMapAVL inspired by recent changes of FSetAVL: letouzey
* pure functions comes first, proofs are isolated in a sub-module * lazy (&&&) = if ... then ... else true instead of strict (&&) = andb * equal and compare done via continuations * a more clever map2_opt suggested by B. Gregoire: no more intermediate conversion to lists, some sub-functions can handle trivial situations, etc. * map2 is now done via map2_opt and another new iterator: map_option. By the way, this map_option allows to define easily an efficient filter function. Both map2_opt and map_option are currently not available through FMapInterface.S, but they can be used by direct reference to the underlying Raw module. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@10745 85f007b7-540e-0410-9357-904b9bb8a0f7
2008-03-15Reorganisation of FSetAVL (consequences of remarks by B. Gregoire)letouzey
* FSetAVL is greatly lightened : modulo a minor change in bal, formal proofs of avl invariant is not needed for building a functor implementing FSetInterface.S (even if this invariant is still true) * Non-structural functions (union, subset, compare, equal) are transformed into efficient structural versions * Both proofs of avl preservation and non-structural functions are moved to a new file FSetFullAVL, that can be ignored by the average user. Same for FMapAVL (still work in progress...) git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@10679 85f007b7-540e-0410-9357-904b9bb8a0f7

2008-02-28Some suggestions about FMap by P. Casteran: letouzey

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
2007-07-18A generic preprocessing tactic zify for (r)omegaletouzey
------------------------------------------------ See file PreOmega for more details and/or test-suite/succes/*Omega*.v The zify tactic performs a Z-ification of your current goal, transforming parts of type nat, N, positive, taking advantage of many equivalences of operations, and of the positivity implied by these types. Integration with omega and romega: (r)omega : the earlier tactics, 100% compatible (r)omega with * : full zify applied before the (r)omega run (r)omega with <types>, where <types> is a sub-list of {nat,N,positive,Z}, applies only specific parts of zify (btw "with Z" means take advantage of Zmax, Zmin, Zabs and Zsgn). As a particular consequence, "romega with nat" should now be a close-to-perfect replacement for omega. Slightly more powerful, since (forall x:nat, x*x>=0) is provable and also slightly less powerful: if False is somewhere in the hypothesis, it doesn't use it. For the moment zify is done in a direct way in Ltac, using rewrite when necessary, but crucial chains of rewrite may be made reflexive some day. Even though zify is designed to help (r)omega, I think it might be of interest for other tactics (micromega ?). Feel free to complete zify if your favorite operation / type isn't handled yet. Side-effects: - additional results for ZArith, NArith, etc... - definition of Ple, Plt, Pgt, Pge and notations for them in positive_scope - romega now start by doing "intros". Since the conclusion will be negated, and this operation will be justified by means of decidability, it helps to have as little as possible in the conclusion. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@10028 85f007b7-540e-0410-9357-904b9bb8a0f7
