* Remove many superfluous 'open' indicated by ocamlc -w +33Gravatar Pierre Letouzey2014-03-05
| | | | | | | | With ocaml 4.01, the 'unused open' warning also checks the mli :-) Beware: some open are reported as useless when compiling with camlp5, but are necessary for compatibility with camlp4. These open are now marked with a comment.
* 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

* Makes the new Proofview.tactic the basic type of Ltac.Gravatar aspiwack2013-11-02
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On the compilation of Coq, we can see an increase of ~20% compile time on my completely non-scientific tests. Hopefully this can be fixed. There are a lot of low hanging fruits, but this is an iso-functionality commit. With a few exceptions which were not necessary for the compilation of the theories: - The declarative mode is not yet ported - The timeout tactical is currently deactivated because it needs some subtle I/O. The framework is ready to handle it, but I haven't done it yet. - For much the same reason, the ltac debugger is unplugged. It will be more difficult, but will eventually be back. A few comments: I occasionnally used a coercion from [unit Proofview.tactic] to the old [Prooftype.tactic]. It should work smoothely, but loses any backtracking information: the coerced tactics has at most one success. - It is used in autorewrite (it shouldn't be a problem there). Autorewrite's code is fairly old and tricky - It is used in eauto, mostly for "Hint Extern". It may be an issue as time goes as we might want to have various success in a "Hint Extern". But it would require a heavy port of eauto.ml4 - It is used in typeclass eauto, but with a little help from Matthieu, it should be easy to port the whole thing to the new tactic engine, actually simplifying the code. - It is used in fourier. I believe it to be inocuous. - It is used in firstorder and congruence. I think it's ok. Their code is somewhat intricate and I'm not sure they would be easy to actually port. - It is used heavily in Function. And honestly, I have no idea whether it can do harm or not. Updates: (11 June 2013) Pierre-Marie Pédrot contributed the rebase over his new stream based architecture for Ltac matching (r16533), which avoid painfully and expensively working around the exception-throwing control flow of the previous API. (11 October 2013) Rebasing over recent commits (somewhere in r16721-r16730) rendered a major bug in my implementation of Tacticals.New.tclREPEAT_MAIN apparent. It caused Field_theory.v to loop. The bug made rewrite !lemma, rewrite ?lemma and autorewrite incorrect (tclREPEAT_MAIN was essentially tclREPEAT, causing rewrites to be tried in the side-conditions of conditional rewrites as well). The new implementation makes Coq faster, but it is pretty much impossible to tell if it is significant at all. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@16967 85f007b7-540e-0410-9357-904b9bb8a0f7

* Added support for Ltac-matching terms with variables bound in the patternGravatar herbelin2010-06-06
| | | | | | | | | | | | | | | | | | - Instances found by matching.ml now collect the set of bound variables they possibly depend on in the pattern (see type Pattern.extended_patvar_map); the variables names are canonically ordered so that non-linear matching takes actual names into account. - Removed typing of matching constr instances in advance (in tacinterp.ml) and did it only at use time (in pretyping.ml). Drawback is that we may have to re-type several times the same term but it is necessary for considering terms with locally bound variables of which we do not keep the type (and if even we had kept the type, we would have to adjust the indices to the actual context the term occurs). - A bit of documentation of pattern.mli, matching.mli and pretyping.mli. - Incidentally add env while printing idtac messages. It seems more correct and I hope I did not break some intended existing behavior. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@13080 85f007b7-540e-0410-9357-904b9bb8a0f7

* Here comes the commit, announced long ago, of the new tactic engine.Gravatar aspiwack2010-04-22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is a fairly large commit (around 140 files and 7000 lines of code impacted), it will cause some troubles for sure (I've listed the know regressions below, there is bound to be more). At this state of developpement it brings few features to the user, as the old tactics were ported with no change. Changes are on the side of the developer mostly. Here comes a list of the major changes. I will stay brief, but the code is hopefully well documented so that it is reasonably easy to infer the details from it. Feature developer-side: * Primitives for a "real" refine tactic (generating a goal for each evar). * Abstract type of tactics, goals and proofs * Tactics can act on several goals (formally all the focused goals). An interesting consequence of this is that the tactical (. ; [ . | ... ]) can be separated in two tacticals (. ; .) and ( [ . | ... ] ) (although there is a conflict for this particular syntax). We can also imagine a tactic to reorder the goals. * Possibility for a tactic to pass a value to following tactics (a typical example is an intro function which tells the following tactics which name it introduced). * backtracking primitives for tactics (it is now possible to implement a tactical '+' with (a+b);c equivalent to (a;c+b;c) (itself equivalent to (a;c||b;c)). This is a valuable tool to implement tactics like "auto" without nowing of the implementation of tactics. * A notion of proof modes, which allows to dynamically change the parser for tactics. It is controlled at user level with the keywords Set Default Proof Mode (this is the proof mode which is loaded at the start of each proof) and Proof Mode (switches the proof mode of the current proof) to control them. * A new primitive Evd.fold_undefined which operates like an Evd.fold, except it only goes through the evars whose body is Evar_empty. This is a common operation throughout the code, some of the fold-and-test-if-empty occurences have been replaced by fold_undefined. For now, it is only implemented as a fold-and-test, but we expect to have some optimisations coming some day, as there can be a lot of evars in an evar_map with this new implementation (I've observed a couple of thousands), whereas there are rarely more than a dozen undefined ones. Folding being a linear operation, this might result in a significant speed-up. * The declarative mode has been moved into the plugins. This is made possible by the proof mode feature. I tried to document it so that it can serve as a tutorial for a tactic mode plugin. Features user-side: * Unfocus does not go back to the root of the proof if several Focus-s have been performed. It only goes back to the point where it was last focused. * experimental (non-documented) support of keywords BeginSubproof/EndSubproof: BeginSubproof focuses on first goal, one can unfocus only with EndSubproof, and only if the proof is completed for that goal. * experimental (non-documented) support for bullets ('+', '-' and '*') they act as hierarchical BeginSubproof/EndSubproof: First time one uses '+' (for instance) it focuses on first goal, when the subproof is completed, one can use '+' again which unfocuses and focuses on next first goal. Meanwhile, one cas use '*' (for instance) to focus more deeply. Known regressions: * The xml plugin had some functions related to proof trees. As the structure of proof changed significantly, they do not work anymore. * I do not know how to implement info or show script in this new engine. Actually I don't even know what they were suppose to actually mean in earlier versions either. I wager they would require some calm thinking before going back to work. * Declarative mode not entirely working (in particular proofs by induction need to be restored). * A bug in the inversion tactic (observed in some contributions) * A bug in Program (observed in some contributions) * Minor change in the 'old' type of tactics causing some contributions to fail. * Compilation time takes about 10-15% longer for unknown reasons (I suspect it might be linked to the fact that I don't perform any reduction at QED-s, and also to some linear operations on evar_map-s (see Evd.fold_undefined above)). git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@12961 85f007b7-540e-0410-9357-904b9bb8a0f7

* On remplace evar_map par evar_defs (seul evar_defs est désormais exporté Gravatar aspiwack2009-02-19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | par Evd). Ça s'accompagne de quelques autres modifications de l'interface (certaines fonctions étaient des doublons, ou des conversions entre evar_map et evar_defs). J'ai modifié un peu la structure de evd.ml aussi, pour éviter des fonctions redéfinies deux fois (i.e. définies trois fois !), j'ai introduit des sous-modules pour les différentes couches. Il y a à l'heure actuelle une pénalité en performance assez sévère (due principalement à la nouvelle mouture de Evd.merge, si mon diagnostique est correct). Mais fera l'objet de plusieurs optimisations dans les commits à venir. Un peu plus ennuyeux, la test-suite du mode déclaratif ne passe plus. Un appel de Decl_proof_instr.mark_as_done visiblement, je suis pour l'instant incapable de comprendre ce qui cause cette erreur. J'espère qu'on pourra le déterminer rapidement. Ce commit est le tout premier commit dans le trunk en rapport avec les évolution futures de la machine de preuve, en vue en particulier d'obtenir un "vrai refine". git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@11939 85f007b7-540e-0410-9357-904b9bb8a0f7
