* Doc: solve the bad interaction between Declare Implicit Tactic and refine.Gravatar aspiwack2013-11-02
| | | | | | An implicit tactic was declared and made refine fail (trying to solve the open goals of the refined term resulted in an error). There was no way to remove the implicit tactic (it isn't managed by an option so isn't removed by Reset Initial). I added the option under the name Clear Implicit Tactic. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@17032 85f007b7-540e-0410-9357-904b9bb8a0f7

* Documentation for the backtracking features.Gravatar aspiwack2013-11-02
| | | | | | This required some reorganisation of the documentation of existing tacticals. I hope the result is consistent. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@17029 85f007b7-540e-0410-9357-904b9bb8a0f7

* push_rel_context: do not rename section variables.Gravatar aspiwack2013-11-02
| | | | | | Renaming section variables is incorrect. And interacts badly with Hints and Canonical Structures in sections. (bug noticed in ssreflect) git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@17024 85f007b7-540e-0410-9357-904b9bb8a0f7
* Refine now does iota reduction in addition to beta.Gravatar aspiwack2013-11-02
| | | | | | Restores more compatibility with the earlier implementation of refine. Needed in ssreflect. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@17023 85f007b7-540e-0410-9357-904b9bb8a0f7
* Fix compilation of pattern matching wrt variables: alias.Gravatar aspiwack2013-11-02
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Aliases (as clause) are a bit tricky. In Goal True, refine match 0 with | S n as p => _ | _ => I end Must produce the goal n:nat, p := S n : nat |- True However, in the deep branches: refine match 0 with | S (S n as p) => _ | _ => I end The alias is used to give a name to the variable of the first S : p:nat, n:nat |- True Before this patch, the goal would be p:nat, n:nat, p:=p : nat |- True Alias was used both to name the variable of the first S and to alias it. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@17022 85f007b7-540e-0410-9357-904b9bb8a0f7
* Restore Zsqrt compat now that refine works fine with match.Gravatar aspiwack2013-11-02
| | | | git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@17021 85f007b7-540e-0410-9357-904b9bb8a0f7
* Fix the compilation of pattern matching wrt to variables.Gravatar aspiwack2013-11-02
| | | | | | | | Compilation of pattern-matching used to systematically introduce a dummy alias x:=x in the typing environment for each variable x in the patterns (except for purely variable patterns which correctly alias the term being matched). This interfered badly with the new refine implementation. To correct this I changed the "all variables" case of pattern-matching compilation to check whether the term currently being matched is a term introduced by the user or a subterm which is necessarily a variable. In the latter case, no alias is introduced. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@17020 85f007b7-540e-0410-9357-904b9bb8a0f7
* Refine: Tactics.New.refine does beta-reduction.Gravatar aspiwack2013-11-02
| | | | | | | | Previously I had wrapped Tactics.New.refine with extra beta-reduction in extratactics.ml4, that is, only for Ltac. Ocaml plugins saw the version without reduction. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@17019 85f007b7-540e-0410-9357-904b9bb8a0f7
* Adds a tactic give_up.Gravatar aspiwack2013-11-02
| | | | | | Gives up on the focused goals. Shows an unsafe status. Unlike the admit tactic, the proof cannot be closed until the users goes back and solves these goals. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@17018 85f007b7-540e-0410-9357-904b9bb8a0f7
* A tactic shelve_unifiable.Gravatar aspiwack2013-11-02
| | | | | | | | | | | | | Puts on the shelf every goals under focus on which other goals under focus depend. Useful when we want to solve these goals by unification (as in a first order proof search procedure, for instance). Also meant to be able to recover approximately the semantics of the old refine with the new implementation (use refine t; shelve_unifiable). TODO: bug dans l'example de shelve_unifiable git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@17017 85f007b7-540e-0410-9357-904b9bb8a0f7
* Made multiple-goal tactic work after all: .Gravatar aspiwack2013-11-02
| | | | | | | | Internalization was done relative to a goal. It doesn't make sense in the case of all:. When we make a tactic with all: the environment for internalization is taken to be the global environment. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@17016 85f007b7-540e-0410-9357-904b9bb8a0f7
* Make multiple-goal tactics possible after a tclTHEN.Gravatar aspiwack2013-11-02
| | | | | | | | | Tacinterp used to interprete every tactics inside a goal, making multiple-goal tactics act on a single goal anyway. Uses a simple heuristic to decide when a goal is not needed. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@17015 85f007b7-540e-0410-9357-904b9bb8a0f7
* Corrects a bug on Proofview.Goal.enter whereby sigmas were captured and used ↵Gravatar aspiwack2013-11-02
| | | | | | | | | | at the wrong time. The bug was masked by the fact that Tacinterp uses many superfluous Proofview.Goal.enter, it so happens that the tactic Proofview.Goal.enter (fun _ -> Proofview.Goal.enter fun gl -> t)) had the correct semantics! git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@17014 85f007b7-540e-0410-9357-904b9bb8a0f7
* Adds a shelve tactic.Gravatar aspiwack2013-11-02
| | | | | | The shelve tactic puts all the focused goals out of sight. They can be later recalled by the Unshelve command. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@17013 85f007b7-540e-0410-9357-904b9bb8a0f7
* bootstrap/Monad.v: implements the writer monad in continuation passing style.Gravatar aspiwack2013-11-02
| | | | | | | Benefits: fewer pair constructed/destructed especially in split. Potential costs: plus and zero now have closures with 11 arguments. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@17012 85f007b7-540e-0410-9357-904b9bb8a0f7
* bootstrap/Monad.v: implements the environment monad in continuation passing ↵Gravatar aspiwack2013-11-02
| | | | | | | | | style. Benefits: the underlying monads are not referenced in the "current" primitive. Potential costs: some extracted functions now have 9 arguments, Ocaml may not be good at handling these. The split primitive, which is called often, now builds one extra closure. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@17011 85f007b7-540e-0410-9357-904b9bb8a0f7
* Factors the lifting of environment and writer monads in bootstrap/Monad.vGravatar aspiwack2013-11-02
| | | | | | | Takes a few extra lines but is probably more robust to future changes. Doesn't change the extracted code. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@17010 85f007b7-540e-0410-9357-904b9bb8a0f7
* Adds an experimental exactly_once tactical.Gravatar aspiwack2013-11-02
| | | | | | | | | | exactly_once t, will have a success if t has exactly once success. There are a few caveats: - The underlying effects of t may happen in an unpredictable order (hence it may be wise to use it only with "pure" tactics) - The second success of a tactic is conditional on the exception thrown. In Ltac it doesn't show, but in the underlying code, the tactical also expects the exception you want to use to produce the second success. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@17009 85f007b7-540e-0410-9357-904b9bb8a0f7
* Normalise goals with respect to evars in the new tactics.Gravatar aspiwack2013-11-02
| | | | git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@17008 85f007b7-540e-0410-9357-904b9bb8a0f7
* Made Proofview.Goal.hyps a named_context.Gravatar aspiwack2013-11-02
| | | | | | There was really no point in having it be a named_context val. The tactics are not going to access the vm cache. Only vm_compute will. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@17007 85f007b7-540e-0410-9357-904b9bb8a0f7
* Refine does beta-reductions.Gravatar aspiwack2013-11-02
| | | | | | To avoid the unpleasantness of having beta-redex in terms after an application of refine, refine is followed by lazy beta. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@17006 85f007b7-540e-0410-9357-904b9bb8a0f7
* A dedicated view type for Proofview_gen.split.Gravatar aspiwack2013-11-02
| | | | | | It doesn't seem to affect performances. But the generated code is slightly cleaner. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@17005 85f007b7-540e-0410-9357-904b9bb8a0f7
* Adds a tactical once.Gravatar aspiwack2013-11-02
| | | | | | [once t] does just as [t] but has exactly one success it [t] has at least one success. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@17004 85f007b7-540e-0410-9357-904b9bb8a0f7
* Corrects the semantics of the "+" tactical.Gravatar aspiwack2013-11-02
| | | | | | | - Treats goals independently - Honors failure levels git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@17003 85f007b7-540e-0410-9357-904b9bb8a0f7
* Less use of the list-based interface for goal-bound tactics.Gravatar aspiwack2013-11-02
| | | | git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@17002 85f007b7-540e-0410-9357-904b9bb8a0f7
* Tachmach.New is now in Proofview.Goal.enter style.Gravatar aspiwack2013-11-02
| | | | | | As a result the use of the glist-style interface for manipulating goals has almost been removed. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@17001 85f007b7-540e-0410-9357-904b9bb8a0f7
* More Proofview.Goal.enter.Gravatar aspiwack2013-11-02
| | | | | | | | | | Proofview.Goal.enter is meant to eventually replace the Goal.sensitive monad. This commit changes the type of Proofview.Goal.enter from taking a four argument function (environment, evar_map, hyps, concl) from a one argument function of abstract type Proofview.Goal.t. It will be both more extensible and more akin to old-style tactics. This commit also changes the type of Proofview.Goal.{concl,hyps,env} from monadic operations to projection from a Proofview.Goal.t. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@17000 85f007b7-540e-0410-9357-904b9bb8a0f7

* Added the tactical "tac1 + tac2".Gravatar aspiwack2013-11-02
| | | | | | It works pretty much like "tac1 || tac2" except that it has as successes all the successes of tac1 followed by all the successes of tac2 (whereas the latter has either the successes of tac1 (if there is at least one) or those of tac2 (otherwise)). git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@16998 85f007b7-540e-0410-9357-904b9bb8a0f7

* bootstrap/Monads.v: A more efficient split.Gravatar aspiwack2013-11-02
