2012-04-18Corrects a (very) longstanding bug of tactics. As is were, tactic expectingaspiwack
constr as argument (rather than openconstr) assumed that the evar_map output by pretyping was irrelevant as the final constr didn't have any evars. However, if said constr was defined using pre-existing evars from the context, the evars may be instantiated by pretyping, hence dropping the output evar_map led to inconsistent proof terms. This fixes bug #2739 ( https://coq.inria.fr/bugs/show_bug.cgi?id=2739 ). Thanks Arthur for noticing it. Note: change still has the bug, because more serious issues interfered with my fix. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@15207 85f007b7-540e-0410-9357-904b9bb8a0f7

2012-04-15Fixing tauto "special" behavior on singleton types w/ 2 parameters (bug #2680).herbelin
- 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

2012-03-30info_trivial, info_auto, info_eauto, and debug (trivial|auto)letouzey
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

2012-03-18Fixing bug #2732 (anomaly when using the tolerance for writingherbelin
"f atomic_tac" as a short-hand for "f ltac:(atomic_tac)" for "f" an Ltac function - see Tacinterp.add_primitive_tactic). More precisely, when parsing "f ref" and "ref" is recognized as the name of some TACTIC-EXTEND-defined tactic parsable as an atomic tactic (like "eauto", "firstorder", "discriminate", ...), the code was correct only when a rule of the form `TACTIC EXTEND ... [ "foo" -> ...] END' was given (where "foo" has no arguments in the rule) but not when a rule of the form `TACTIC EXTEND ... [ "foo" tactic_opt(p) -> ...] END' was given (where "foo" had an optional argument in the rule). In particular, "firstorder" was in this case. More generally, if, for an extra argument able to parse the empty string, a rule `TACTIC EXTEND ... [ "foo" my_special_extra_arg(p) -> ...] END' was given, then "foo" was not recognized as parseable as an atomic string (this happened e.g. for "eauto"). This is now also fixed. There was also another bug when the internal name of tactic was not the same as the user-level name of the tactic. This is the reason why "congruence" was not recognized when given as argument of an ltac (its internal name is "cc"). Incidentally removed the redundant last line in the parsing rule for "firstorder". git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@15041 85f007b7-540e-0410-9357-904b9bb8a0f7

2011-11-17Merge subinstances branch by me and Tom Prince.msozeau
This adds two experimental features to the typeclass implementation: - Path cuts: a way to specify through regular expressions on instance names search pathes that should be avoided (e.g. [proper_flip proper_flip]). Regular expression matching is implemented through naïve derivatives. - Forward hints for subclasses: e.g. [Equivalence -> Reflexive] is no longer applied backwards, but introducing a specific [Equivalence] in the environment register a [Reflexive] hint as well. Currently not backwards-compatible, the next patch will allow to specify direction of subclasses hints. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@14671 85f007b7-540e-0410-9357-904b9bb8a0f7
