* Change in vo format : digest aren't Marshalled anymoreGravatar letouzey2013-08-22
| | | | | | | | | | | Since digests are strings (of size 16), we just dump them now in vo files (cf. Digest.output) instead of using Marshal on them : this is cleaner and saves a few bytes. Increased VOMAGIC to clearly identify this change in the format. Please rerun ./configure after this commit. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@16722 85f007b7-540e-0410-9357-904b9bb8a0f7
* Revising r16550 about providing intro patterns for applying injection:Gravatar herbelin2013-07-09
| | | | | | | | | | | | - Introduction of a specific notation for injection intropatterns: [= pats] - Use of this specific pattern also to apply discriminate on the fly Note: The automatic injection of dependent tuples over a same first component (introduced in r10180) still not integrated to the main parts of injection and its variant (indeed, it applies only for a root dependent tuple in sigT). git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@16621 85f007b7-540e-0410-9357-904b9bb8a0f7

* Making the behavior of "injection ... as ..." more natural:Gravatar herbelin2013-06-02
| | | | | | | | | | | | | - hypotheses are introduced in the left-to-right order - intropatterns have to match the number of generated hypotheses, and, if less, new introduction names are automatically generated - clearing the hypothesis on which injection is applied, if any. However, this is a source of incompatibilities (for a variant of injection that is hopefully not used a lot). Compatibility can be restored by "Unset Injection L2R Pattern Order". git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@16556 85f007b7-540e-0410-9357-904b9bb8a0f7

* induction/destruct : nicer syntax for generating equations (solves #2741)Gravatar letouzey2012-07-09
| | | | | | | | | | | | | | | | | | The ugly syntax "destruct x as [ ]_eqn:H" is replaced by: destruct x eqn:H destruct x as [ ] eqn:H Some with induction. Of course, the pattern behind "as" is arbitrary. For an anonymous version, H could be replaced by ?. The old syntax with "_eqn" still works for the moment, by triggers a warning. For making this new syntax work, we had to change the seldom-used "induction x y z using foo" into "induction x, y, z using foo". Now, only one "using" can be used per command instead of one per comma-separated group earlier, but I doubt this will bother anyone. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@15566 85f007b7-540e-0410-9357-904b9bb8a0f7
* Quick update to CHANGES, mention especially the new parsing of ->Gravatar letouzey2012-07-05
| | | | | | | | | | | | | | | So -> is at level 99 since commit 15515. In particular it has now *less* priority than <->, i.e. A->B<->C is now parsed as A->(B<->C) instead of the former awkward and beginner-misleading (A->B)<->C. Sorry, I was planning to do a separate commit for that, but I forgot. In fact, the parsing rules for -> were slightly changed during Pierre B's recent conversion of -> to a true Notation, leading to a nasty sitution : A->B<->C->D was parsed as A->(B<->(C->D)). With no obvious solution to restore full compatibility, we decided to go for the parsing described above, both easy to implement and to work with. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@15523 85f007b7-540e-0410-9357-904b9bb8a0f7

| | | | | | | | | | | | | | | | | | Why2 has not been maintained for the last few years and the Why3 plugin should be a suitable replacement in most cases. Removed tactics: simplify, ergo, yices, cvc3, z3, cvcl, harvey, zenon, gwhy. Removed commands: Dp_hint, Dp_timeout, Dp_prelude, Dp_predefined, Dp_debug, Dp_trace. Note that the "admit" tactic was actually provided by the Dp plugin. It has been moved to extratactics.ml4.

* Fixing tauto "special" behavior on singleton types w/ 2 parameters (bug #2680).Gravatar herbelin2012-04-15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | - tauto/intuition now works uniformly on and, prod, or, sum, False, Empty_set, unit, True (and isomorphic copies of them), iff, ->, and on all inhabited singleton types with a no-arguments constructor such as "eq t t" (even though the last case goes out of propositional logic: this features is so often used that it is difficult to come back on it). - New dtauto and dintuition works on all inductive types with one constructors and no real arguments (for instance, they work on records such as "Equivalence"), in addition to -> and eq-like types. - Moreover, both of them no longer unfold inner negations (this is a souce of incompatibility for intuition and evaluation of the level of incompatibility on contribs still needs to be done). Incidentally, and amazingly, fixing bug #2680 made that constants InfA_compat and InfA_eqA in SetoidList.v lost one argument: old tauto had indeed destructed a section hypothesis "@StrictOrder A ltA@ thinking it was a conjunction, making this section hypothesis artificially necessary while it was not. Renouncing to the unfolding of inner negations made auto/eauto sometimes succeeding more, sometimes succeeding less. There is by the way a (standard) problem with not in auto/eauto: even when given as an "unfold hint", it works only in goals, not in hypotheses, so that auto is not able to solve something like "forall P, (forall x, ~ P x) -> P 0 -> False". Should we automatically add a lemma of type "HYPS -> A -> False" in the hint database everytime a lemma ""HYPS -> ~A" is declared (and "unfold not" is a hint), and similarly for all unfold hints? At this occasion, also re-did some proofs of Znumtheory. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@15180 85f007b7-540e-0410-9357-904b9bb8a0f7

* MSetRBT : implementation of MSets via Red-Black treesGravatar letouzey2012-04-13
| | | | | | | | | | | | | | | | | | | Initial contribution by Andrew Appel, many ulterior modifications by myself. Interest: red-black trees maintain logarithmic depths as AVL, but they do not rely on integer height annotations as AVL, allowing interesting performance when computing in Coq or after standard extraction. More on this topic in the article by A. Appel. The common parts of MSetAVL and MSetRBT are shared in a new file MSetGenTree which include the definition of tree and functions such as mem fold elements compare subset. Note that the height of AVL trees is now the first arg of the Node constructor instead of the last one. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@15168 85f007b7-540e-0410-9357-904b9bb8a0f7

* info_trivial, info_auto, info_eauto, and debug (trivial|auto)Gravatar letouzey2012-03-30
| | | | | | | | | | | | | | | | | | | | | | | To mitigate the lack of a general "info" tactical, let's introduce some specialized tactics info_trivial, info_auto and info_eauto that display the basic tactics used when solving a goal. We also add tactics "debug trivial" and "debug auto" which display every basic tactics attempted by trivial or auto. Triggering the "info" or "debug" mode for auto, eauto, trivial can also be done now via global options, such as Set Debug Auto or Set Info Eauto. In case both debug and info modes are activated, the debug mode takes precedence. NB: it would be nice to name these tactics "info xxx" instead of "info_xxx", but I don't see how to implement a "info eauto" in eauto.ml4 (hence by TACTIC EXTEND) while keeping a generic "info foo" tactic in g_ltac.ml4 (useful to display a nice message about the unavailability of the general info). git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@15103 85f007b7-540e-0410-9357-904b9bb8a0f7

Techically, we simply allow the same label to occur at most twice in a structure_body, which is a (label * structure_field_body) list). These two label occurences should not be at the same level of fields (e.g. a SFBmodule and a SFBmind are ok, but not two SFBmodule's or a SFBmodule and a SFBmodtype). Gain : a minimal amount of code change.
