* Noise for nothingGravatar pboutill2012-03-02
| | | | | | | | | | | Util only depends on Ocaml stdlib and Utf8 tables. Generic pretty printing and loc functions are in Pp. Generic errors are in Errors. + Training white-spaces, useless open, prlist copies random erasure. Too many "open Errors" on the contrary. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@15020 85f007b7-540e-0410-9357-904b9bb8a0f7
* Merge subinstances branch by me and Tom Prince.Gravatar msozeau2011-11-17
| | | | | | | | | | | | | | 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

* 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

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | branch and remove equations stuff which moves to a separate plugin. Classes: - Ability to define classes post-hoc from constants or inductive types. - Correctly rebuild the hint database associated to local hypotheses when they are changed by a [Hint Extern] in typeclass resolution. Tactics and proofs: - Change [revert] so that it keeps let-ins (but not [generalize]). - Various improvements to the [generalize_eqs] tactic to make it more robust and produce the smallest proof terms possible. Move [specialize_hypothesis] in tactics.ml as it goes hand in hand with [generalize_eqs]. - A few new general purpose tactics in Program.Tactics like [revert_until] - Make transitive closure well-foundedness proofs transparent. - More uniform testing for metas/evars in pretyping/unification.ml (might introduce a few changes in the contribs). Program: - Better sorting of dependencies in obligations. - Ability to start a Program definition from just a type and no obligations, automatically adding an obligation for this type. - In compilation of Program's well-founded definitions, make the functional a separate definition for easier reasoning. - Add a hint database for every Program populated by [Hint Unfold]s for every defined obligation constant. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@12440 85f007b7-540e-0410-9357-904b9bb8a0f7

* Some dead code removal + cleanupsGravatar letouzey2009-04-08
| | | | | | | | | | | | | | This commit concerns about the first half of the useless code mentionned by Oug for coqtop (without plugins). For the moment, Oug is used in a mode where any elements mentionned in a .mli is considered to be precious. This already allows to detect and remove about 600 lines, and more is still to come. Among the interesting points, the type Entries.specification_entry and its constructors SPExxx were never used. Large parts of cases.ml (and hence subtac_cases.ml) were also useless. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@12069 85f007b7-540e-0410-9357-904b9bb8a0f7

This is virtual in the sense that it is not activated since it breaks compatibility with the existing tauto. - Modified the notion of conjunction and unit type used in hipattern in a way that is closer to the intuitive meaning (forbid dependencies between parameters in conjunction; forbid indices in unit types). - Investigated how far "iff" could be turned into a direct inductive definition; modified tauto.ml4 so that it works with the current and the alternative definition. - Fixed a bug in the error message from lookup_eliminator. - Other minor changes. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@11721 85f007b7-540e-0410-9357-904b9bb8a0f7

* Add the ability to declare [Hint Extern]'s with no pattern.Gravatar msozeau2008-09-07
| | | | | | | | | | | | | | | This permits to create a database [relations] in [RelationClasses] with a single extern tactic in it that tries to apply [reflexivity] or [symmetry]. This is then automatically used in [auto with *] and repair backward compatibility. The previous commit broke some scripts which were using [intuition] to do (setoid) [reflexivity] or [symmetry]: this worked only by accident, because the hint database of typeclasses was used. Overrall, this also allows to put a bunch of always-applicable, related tactics in some database or to use [Hint Extern] but match only on hypotheses. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@11384 85f007b7-540e-0410-9357-904b9bb8a0f7

| | | | | | | | | | | | | | | | | goals containing existentials and use transparency information on constants (optionally). Only used by the typeclasses eauto engine for now, but could be used for other hint bases easily (just switch a boolean). Had to add a new "creation" hint to be able to set said boolean upon creation of the typeclass_instances hint db. Improve the proof-search algorithm for Morphism, up to 10 seconds gained in e.g. Field_theory, Ring_polynom. Added a morphism declaration for [compose]. One needs to declare more constants as being unfoldable using the [Typeclasses unfold] command so that discrimination is done correctly, but that amounts to only 6 declarations in the standard library. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@11184 85f007b7-540e-0410-9357-904b9bb8a0f7

Debugging the tactic I found missing morphisms that are now in Morphisms.v and removed some that made proof search fail or take too long, not sure it's complete however. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@10565 85f007b7-540e-0410-9357-904b9bb8a0f7

* Factorisation des opérations sur le type option de Util dans un module Gravatar aspiwack2007-12-05
| | | | | | | | | | | | | | | | | | | | | | | | | | | lib/option.ml(i) . J'en profite pour rajouter des primitives de lifting des fonctions (à un ou deux arguments tous ou partie de type option). Il reste quelques opérations dans Util à propos desquelles je ne suis pas trop sûr, ou simplement que j'ai oublié, mais qui attendront demain car il est tard (comme some_in qui devrait devenir Option.make je suppose) . Elles s'expriment souvent facilement en fonction des autres, par exemple "option_compare x y" est égal à "Option.lift2 compare x y" . Le option_cons devrait faire son chemin dans le module parce qu'il est assez primitif et qu'il n'y a pas de fonction "cons" dans OCaml. J'en ai profité aussi pour remplacer les trop nombreux "failwith" par des erreurs locales au module, donc plus robustes. J'ai trouvé aussi une fonction qui était définie deux fois, et une définie dans un module particulier. Mon seul bémol (mais facile à traiter) c'est la proximité entre le nom de module Option et l'ancien Options. J'ai pas de meilleure idée de nom à l'heure qu'il est, ni pour l'un, ni pour l'autre. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@10346 85f007b7-540e-0410-9357-904b9bb8a0f7

* Nouvelle stratégie d'unification des types des with-bindings dansGravatar herbelin2007-05-22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | apply afin de reculer au plus tard les décisions irréversibles et en particulier de pouvoir typer les with-bindings modulo coercions : - l'unification des types des métas données en with-bindings est retardé à après l'unification (unify_0) de telle sorte que les instances trouvées par unify_0 soient prioritaires et que la décision d'insérer éventuellement des coercions autour des valeurs données en with-bindings se fasse au dernier moment; - toujours pour permettre d'insérer ultimement des coercions, l'instantiation des with-bindings ne se fait plus l'appel unify_0 (cf clenv_unique_resolver); - pour permettre ce retardement sans limiter le test de conversion que unify_0 fait sur les termes clos, on transmet à unify_0 les métas données en with-bindings (ainsi l'instantiation de ces métas peut être faite dynamiquement au moment du test de clôture); - parce que les métas données en with-bindings qui sont en position de rédex (cas d'un "apply f_equal with (f:=fun ...)" peuvent simplifier le problème d'unification (et elles ne sont pas de toutes façons pas réinférables au premier ordre), on continue à les substituer avant l'appel à unify_0 (cf meta_reducible_instance); - pour l'unification du second-ordre, on continue d'instancier les with-bindings et d'unifier les types des with-bindings avant unification; - reste à régler un problème de compatibilité lorsque le résultat de l'unification des types des with-bindings est utilisé pour rendre un terme clos et pour permettre à unify_0 d'utiliser la conversion. + meilleure compatibilité de apply, split, left, right pour le code qui l'utilise avec des bindings clos + nettoyage et uniformisation des clenv_match_args, clenv_missing, et assimilés git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@9850 85f007b7-540e-0410-9357-904b9bb8a0f7
