2009-10-08Implicit argument of Logic.eq become maximally insertedletouzey
This allow in particular to write eq instead of (@eq _) in signatures of morphisms. I dont really see how this could break existing code, no change in the stdlib was mandatory. We'll check the contribs tomorrow... git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@12379 85f007b7-540e-0410-9357-904b9bb8a0f7
2009-10-05Correctly do backtracking during type class resolution even if only newmsozeau
existentials are generated (at last!). The code simply keeps failure continuations and apply them if needed. Fix bottomup and topdown rewrite strategies that looped. Use auto introduction flag for typeclass instances as well. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@12374 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

2009-09-11Added the following lemmas to homogenize Reals a bit:gmelquio
- Rmult_eq_compat_r, Rmult_eq_reg_r, Rplus_le_reg_r, Rmult_lt_reg_r, Rmult_le_reg_r (mirrored variants of the existing _l lemmas); - minus_IZR, opp_IZR (Ropp_Ropp_IZR), abs_IZR (mirrored Rabs_Zabs); - Rle_abs (RRle_abs); - Zpower_pos_powerRZ (signed variant of Zpower_nat_powerRZ). git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@12321 85f007b7-540e-0410-9357-904b9bb8a0f7

2009-09-09Znumtheory + Zdiv enriched with stuff from ZMicromega, misc improvementsletouzey
Mostly results about Zgcd (commutativity, associativity, ...). Slight improvement of ZMicromega. Beware: some lemmas of Zdiv/ Znumtheory were asking for too strict or useless hypothesis. Some minor glitches may occur. By the way, some iff lemmas about negb in Bool.v git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@12313 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". Fix [is_applied_rewrite_relation]'s bad handling of evars and the environment. Fix some [dual] hints in RelationClasses.v and assert that any declared [Equivalence] can be considered a [RewriteRelation]. Fix minor tex output problem in coqdoc. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@12310 85f007b7-540e-0410-9357-904b9bb8a0f7

2009-08-04- Add more precise error localisation when one of the application failsherbelin
in a chain of apply or apply-in. - Improved comments on the notions of permutation used in the library (still the equality relation in file Permutation.v misses the property of being effectively an equivalence relation, hence missing expected properties of this notion of permutation). git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@12261 85f007b7-540e-0410-9357-904b9bb8a0f7
2009-08-03Added "etransitivity".herbelin
Added support for "injection" and "discriminate" on JMeq. Seized the opportunity to update coqlib.ml and to rely more on it for finding the equality lemmas. Fixed typos in coqcompat.ml. Propagated symmetry convert_concl fix to transitivity (see 11521). git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@12259 85f007b7-540e-0410-9357-904b9bb8a0f7

2009-07-24Remove the barely-used/obsolete/undocumented syntax "conditional <tac> rewrite"letouzey

2009-07-22Better comparison functions in OrderedTypeExletouzey
The compare functions are still functions-by-tactics, but now their computational parts are completely pure (no use of lt_eq_lt_dec in nat_compare anymore), while their proofs parts are simply calls to (opaque) lemmas. This seem to improve the efficiency of sets/maps, as mentionned by T. Braibant, D. Pous and S. Lescuyer. The earlier version of nat_compare is now called nat_compare_alt, there is a proof of equivalence named nat_compare_equiv. By the way, various improvements of proofs, in particular in Pnat. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@12247 85f007b7-540e-0410-9357-904b9bb8a0f7

2009-07-09Use the proper unification flags in e_exact. This makes exact fail a bitmsozeau
more often but respects the spec better. The changes in the stdlib are reduced to adding a few explicit [unfold]s in FMapFacts (exact was doing conversion with delta on open terms in that case). Also fix a minor bug in typeclasses not seeing typeclass evars when their type was a (defined) evar itself. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@12238 85f007b7-540e-0410-9357-904b9bb8a0f7

2009-06-07- Added two new introduction patterns with the following temptative syntaxes:herbelin
- "*" implements Arthur Charguéraud's "introv" - "**" works as "; intros" (see also "*" in ssreflect). - Simplifying the proof of Z_eq_dec, as suggested by Frédéric Blanqui. - Shy attempt to seize the opportunity to clean Zarith_dec but Coq's library is really going anarchically (see a summary of the various formulations of total order, dichotomy of order and decidability of equality and in stdlib-project.tex in branch V8revised-theories). git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@12171 85f007b7-540e-0410-9357-904b9bb8a0f7

2009-05-20Many fixes in unification:msozeau
- Restore failure when types don't unify in [unify_types] (undoing r12075) but try to be more clever about cumulativity using the meta's [instance_status] information. - Fix second-order abstraction when K is not allowed to ensure that we don't unify twice with the same subterm in [w_unify_to_subterm_list]. A more elaborate solution would be give the list to [w_unify_to_subterm] so that it keeps going when it finds an already-found instantiation. - Two "obvious" errors fixed: taking the wrong instance status when unifying with a meta on the right and forgoting type equations in [w_merge]. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@12136 85f007b7-540e-0410-9357-904b9bb8a0f7

- Decorate proof search with depth/subgoal number information - Add a tactic [autoapply foo using hints] to call the resolution tactic with the [transparent_state] associated with a hint db, giving better control over unfolding. - Fix a bug in the Lambda case in the new rewrite - More work on the [Proper] and [subrelation] hints to cut the search space while retaining completeness. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@12118 85f007b7-540e-0410-9357-904b9bb8a0f7
