2008-09-07Add the ability to declare [Hint Extern]'s with no pattern.msozeau
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
2008-09-07Fixes in typeclasses resolution. Avoid reducing instances types beforemsozeau
making the auto apply entry. Makes indexing better and avoid polution of [auto with *] with many abstract lemmas comming from [typeclass_instances]. Quite a nice speedup again, even Field_theory has dropped to 58s from 70s. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@11381 85f007b7-540e-0410-9357-904b9bb8a0f7
2008-08-22- New auto hints for transparency/opacity control, not bound to msozeau
syntax yet. Doesn't change the auto/eauto behavior either. - Typeclass resolution now considers everything transparent by default and does it consistently for "open" and closed terms. - Correctly declare singleton classes definition as opaque for proof search. - Add a few initial declarations to make iff, id, compose... opaque - Add definition of dependent signatures for dependent function types and remove corresponding exception code in class_tactics. The instance requires higher-order unification and is not really usable yet. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@11333 85f007b7-540e-0410-9357-904b9bb8a0f7

- evarconv: mauvaise idée d'utiliser la conversion sur la tête d'un terme applicatif au moment de tester f u1 .. un = g v1 .. vn au premier ordre : on revient sur l'algo tel qu'il était avant le commit 11187. - Bug #1887 (format récursif cassé à cause de la vérification des idents). - Nouveau choix de formattage du message "Tactic Failure". - Nettoyage vocabulaire "match context" -> "match goal" au passage. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@11305 85f007b7-540e-0410-9357-904b9bb8a0f7
2008-08-04Évolutions diverses et variées.herbelin
- Correction divers messages d'erreur - lorsque rien à réécrire dans une hyp, - lorsqu'une variable ltac n'est pas liée, - correction anomalie en présence de ?id dans le "as" de induction, - correction mauvais env dans message d'erreur de unify_0. - Diverses extensions et améliorations - "specialize" : - extension au cas (fun x1 ... xn => H u1 ... un), - renommage au même endroit. - "assert" et "pose proof" peuvent réutiliser la même hyp comme "specialize". - "induction" - intro des IH toujours au sommet même si induction sur var quantifiée, - ajout d'un hack pour la reconnaissance de schémas inductifs comme N_ind_double mais il reste du boulot pour reconnaître (et/ou réordonner) les composantes d'un schéma dont les hypothèses ne sont pas dans l'ordre standard, - vérification de longueur et éventuelle complétion des intropatterns dans le cas de sous-patterns destructifs dans induction (par exemple "destruct n as [|[|]]" sur "forall n, n=0" ne mettait pas le n dans le contexte), - localisation des erreurs d'intropattern, - ajout d'un pattern optionnel après "as" pour forcer une égalité et la nommer (*). - "apply" accepte plusieurs arguments séparés par des virgules (*). - Plus de robustesse pour clear en présence d'evars. - Amélioration affichage TacFun dans Print Ltac. - Vieux pb espace en trop en tête d'affichage des tactiques EXTEND résolu (incidemment, ça remodifie une nouvelle fois le test output Fixpoint.v !). - Fusion VTactic/VFun dans l'espoir. - Mise en place d'un système de trace de la pile des appels Ltac (tout en préservant certains aspects de la récursivité terminale - cf bug #468). - Tactiques primitives - ajout de "move before" dans les tactiques primitives et ajout des syntaxes move before et move dependent au niveau utilisateur (*), - internal_cut peuvent faire du remplacement de nom d'hypothèse existant, - suppression de Intro_replacing et du code sous-traitant - Nettoyage - Suppression cible et fichiers minicoq non portés depuis longtemps.

2008-06-27Enhanced discrimination nets implementation, which can now work withmsozeau
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
2008-06-16Add possibility to match on defined hypotheses, using brackets tomsozeau
disambiguate syntax: [ H := [ ?x ] : context C [ foo ] |- _ ] is ok, as well as [ H := ?x : nat |- _ ] or [H := foo |- _ ], but [ H := ?x : context C [ foo ] ] will not parse. Add applicative contexts in tactics match, to be able to match arbitrary partial applications, e.g.: match f 0 1 2 with appcontext C [ f ?x ] => ... end will bind C to [ ∙ 1 2 ] and x to 0.

2008-06-10- Officialisation de la notation "pattern c at -1" (cf wish 1798 sur coq-bugs)herbelin
- Changement au passage de la convention "at -n1 ... -n2" en "at - n1 ... n2" qui me paraît plus clair à partir du moment où on peut pas mélanger des positifs et des négatifs. - Au passage: - simplification de gclause avec fusion de onconcl et concl_occs, - généralisation de l'utilisation de la désignation des occurrences par la négative aux cas de setoid_rewrite, clrewrite et rewrite at, - correction d'un bug de "rewrite in at" qui utilisait le at de la conclusion dans les hyps. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@11094 85f007b7-540e-0410-9357-904b9bb8a0f7
2008-06-08- Extension de "generalize" en "generalize c as id at occs".herbelin
- Ajout clause "in" à "remember" (et passage du code en ML). - Ajout clause "in" à "induction"/"destruct" qui, en ce cas, ajoute aussi une égalité pour se souvenir du terme sur lequel l'induction ou l'analyse de cas s'applique. - Ajout "pose t as id" en standard (Matthieu: j'ai enlevé celui de Programs qui avait la sémantique de "pose proof" tandis que le nouveau a la même sémantique que "pose (id:=t)"). - Un peu de réorganisation, uniformisation de noms dans Arith, et ajout EqNat dans Arith. - Documentation tactiques et notations de tactiques. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@11072 85f007b7-540e-0410-9357-904b9bb8a0f7
2008-05-30Improvements on coqdoc by adding more information into .globmsozeau
files, about definitions and type of references. - Add missing location information on fixpoints/cofixpoint in topconstr and syntactic definitions in vernacentries for correct dumping. - Dump definition information in vernacentries: defs, constructors, projections etc... - Modify coqdoc/index.mll to use this information instead of trying to scan the file. - Use the type information in latex output, update coqdoc.sty accordingly. - Use the hyperref package to do crossrefs between definition and references to coq objects in latex. Next step is to test and debug it on bigger developments. On the side: - Fix Program Let which was adding a Global definition. - Correct implicits for well-founded Program Fixpoints. - Add new [Method] declaration kind. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@11024 85f007b7-540e-0410-9357-904b9bb8a0f7

2008-05-12- Add -unicode flag to coqtop (sets Flags.unicode_syntax). Used tomsozeau
change the default pretty-printing to use Π, λ instead of forall and fun (and allow "," as well as "=>" for "fun" to be more consistent with the standard forall and exists syntax). Parsing allows theses new forms too, even if not in -unicode, and does not make Π or λ keywords. As usual, criticism and suggestions are welcome :) Not sure what to do about "->"/"→" ? - [setoid_replace by] now uses tactic3() to get the right parsing level for tactics. - Type class [Instance] names are now mandatory. - Document [rewrite at/by] and fix parsing of occs to support their combination. - Backtrack on [Enriching] modifier, now used exclusively in the implementation of implicit arguments. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@10921 85f007b7-540e-0410-9357-904b9bb8a0f7
2008-05-11- Cleanup parsing of binders, reducing to a single production for allmsozeau
binders. - Change syntax of type class instances to better match the usual syntax of lemmas/definitions with name first, then arguments ":" instance. Update theories/Classes accordingly. - Correct globalization of tactic references when doing Ltac :=/::=, update documentation. - Remove the not so useful "(x &)" and "{{x}}" syntaxes from Program.Utils, and subset_scope as well. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@10919 85f007b7-540e-0410-9357-904b9bb8a0f7

2008-05-06Postpone the search for the recursive argument index from the user givenmsozeau
name after internalisation, to get the correct behavior with typeclass binders. This simplifies the pretty printing and translation of the recursive argument name in various places too. Use this opportunity to factorize the different internalization and interpretation functions of binders as well. This definitely fixes part 2 of bug #1846 and makes it possible to use fixpoint definitions with typeclass arguments in program too, with an example given in EquivDec. At the same time, one fix and one enhancement in Program: - fix a de Bruijn bug in subtac_cases - introduce locations of obligations and use them in case the obligation tactic raises a failure when tried on a particular obligation, as suggested by Sean Wilson. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@10889 85f007b7-540e-0410-9357-904b9bb8a0f7

2008-04-23Prise en compte des coercions dans les clauses "with" même si le typeherbelin
de l'argument donné contient des métavariables (souhait #1408). Beaucoup d'infrastructure autour des constantes pour cela mais qu'on devrait pouvoir récupérer pour analyser plus finement le comportement des constantes en général : 1- Pour insérer les coercions, on utilise une transformation (expérimentale) de Metas vers Evars le temps d'appeler coercion.ml. 2- Pour la compatibilité, on s'interdit d'insérer une coercion entre classes flexibles parce que sinon l'insertion de coercion peut prendre précédence sur la résolution des evars ce qui peut changer les comportements (comme dans la preuve de fmg_cs_inv dans CFields de CoRN). 3- Pour se souvenir rapidement de la nature flexible ou rigide du symbole de tête d'une constante vis à vis de l'évaluation, on met en place une table associant à chaque constante sa constante de tête (heads.ml) 4- Comme la table des constantes de tête a besoin de connaître l'opacité des variables de section, la partie tables de declare.ml va dans un nouveau decls.ml. Au passage, simplification de coercion.ml, correction de petits bugs (l'interface de Gset.fold n'était pas assez générale; specialize cherchait à typer un terme dans un mauvais contexte d'evars [tactics.ml]; whd_betaiotazeta avait un argument env inutile [reduction.ml, inductive.ml]) et nettoyage (declare.ml, decl_kinds.ml, avec incidence sur class.ml, classops.ml et autres ...; uniformisation noms tables dans autorewrite.ml). git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@10840 85f007b7-540e-0410-9357-904b9bb8a0f7
2008-04-21- Parameterize unification by two sets of transparent_state, one for openmsozeau
term unification (for constant and variable delta unfolding) and one to parameterize closed-term conversion. Most of the time conversion uses full delta and unification does no delta. This fine-grain is used in rewrite/setoid_rewrite, where only closed-term delta on global constants is allowed. - Interpret Hint Unfold as a directive for delta conversion in auto/eauto when applying lemmas (i.e., for Resolve and Immediate hints). - Remove ad-hoc support for this in typeclasses. Now setoid_rewrite works correctly w.r.t. the old version regarding local definitions. - Fix closed bugs which needed updating due to syntax modifications. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@10824 85f007b7-540e-0410-9357-904b9bb8a0f7
2008-04-15- Add "Global" modifier for instances inside sections with the usualmsozeau
semantics. - Add an Equivalence instance for pointwise equality from an Equivalence on the codomain of a function type, used by default when comparing functions with the Setoid's ===/equiv. - Partially fix the auto hint database "add" function where the exact same lemma could be added twice (happens when doing load for example). git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@10797 85f007b7-540e-0410-9357-904b9bb8a0f7

2008-03-28- Second pass on implementation of let pattern. Parse "let ' par [as x]?msozeau
[in I] := t [return pred] in b", just as SSReflect does with let:. Change implementation: no longer a separate AST node, just add a case_style annotation on Cases to indicate it (if ML was dependently typed we could ensure that LetPatternStyle Cases have only one term to be matched and one branch, alas...). This factors out most code and we lose no functionality (win ! win !). Add LetPat.v test suite. - Slight improvement of inference of return clauses for dependent pattern matching. If matching a variable of non-dependent type under a tycon that mentions it while giving no return clause, the dependency will be automatically infered. Examples at the end of DepPat. Should get rid of most explicit returns under tycons. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@10727 85f007b7-540e-0410-9357-904b9bb8a0f7
2008-03-07f_equal, revert, specialize in ML, contradict in better Ltac (+doc)letouzey
* "f_equal" is now a tactic in ML (placed alongside congruence since it uses it). Normally, it should be completely compatible with the former Ltac version, except that it doesn't suffer anymore from the "up to 5 args" earlier limitation. * "revert" also becomes an ML tactic. This doesn't bring any real improvement, just some more uniformity with clear and generalize. * The experimental "narrow" tactic is removed from Tactics.v, and replaced by an evolution of the old & undocumented "specialize" ML tactic: - when specialize is called on an hyp H, the specialization is now done in place on H. For instance "specialize (H t u v)" removes the three leading forall of H and intantiates them by t u and v. - otherwise specialize still works as before (i.e. as a kind of generalize). See the RefMan and test-suite/accept/specialize.v for more infos. Btw, specialize can still accept an optional number for specifying how many premises to instantiate. This number should normally be useless now (some autodetection mecanism added). Hence this feature is left undocumented. For the happy few still using specialize in the old manner, beware of the slight incompatibities... * finally, "contradict" is left as Ltac in Tactics.v, but it has now a better shape (accepts unfolded nots and/or things in Type), and also some documentation in the RefMan git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@10637 85f007b7-540e-0410-9357-904b9bb8a0f7
2008-03-07Fix bug #1704 (ordering of condition goals for (setoid)rewrite). As partmsozeau
of the fix I added an optional "by" annotation for rewrite to solve said conditions in the same tactic call. Most of the theories have been updated, only FSets is missing, Pierre will take care of it. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@10634 85f007b7-540e-0410-9357-904b9bb8a0f7
2008-03-06Syntax changes in typeclasses, remove "?" for usual implicit argumentsmsozeau
binding, add "!" syntax for the new binders which require parameters and not superclasses. Change backquotes for curly braces for user-given implicit arguments, following tradition. This requires a hack a la lpar-id-coloneq. Change ident to global for typeclass names in class binders. Also requires a similar hack to distinguish between [ C t1 tn ] and [ c : C t1 tn ]. Update affected theories. While hacking the parsing of { wf }, factorized the two versions of fix annotation parsing that were present in g_constr and g_vernac. Add the possibility of the user optionaly giving the priority for resolve and exact hints (used by type classes). Syntax not fixed yet: a natural after the list of lemmas in "Hint Resolve" syntax, a natural after a "|" after the instance constraint in Instance declarations (ex in Morphisms.v). git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@10628 85f007b7-540e-0410-9357-904b9bb8a0f7
2008-03-01Rework on rich forms of rewriteletouzey
1) changed the semantics of rewrite H,H' : the earlier semantics (rewrite H,H' == rewrite H; rewrite H') was poorly suited for situations where first rewrite H generates side-conditions. New semantics is tclTHENFIRST instead of tclTHEN, that is side-conditions are left untouched. Note to myself: check if side-effect-come-first bug of setoid rewrite is still alive, and do something if yes 2) new syntax for rewriting something many times. This syntax is shamelessly taken from ssreflect: rewrite ?H means "H as many times as possible" (i.e. almost repeat rewrite H, except that possible side-conditions are left apart as in 1) rewrite !H means "at least once" (i.e. rewrite H; repeat rewrite H) rewrite 3?H means "up to 3 times", maybe less (i.e. something like: do 3 (try rewrite H)). rewrite 3!H means "exactly 3 times" (i.e. almost do 3 rewrite H). For instance: rewrite 3?foo, <-2!bar in H1,H2|-* 3) By the way, for a try, I've enabled the syntax +/- as synonyms for ->/<- in the orientation of rewrite.

Par exemple, dans Ltac is := let rec i := match goal with |- ?A -> ?B => intro; i | _ => idtac end in i. l'évaluation de i est paresseuse, alors que dans une version non récursive Ltac is := let i := match goal with |- ?A -> ?B => intro | _ => idtac end in i. l'évaluation de i est forte (et échoue sur le "match" qui n'est pas autorisé à retourner une tactique).

2007-12-06Plus de combinateurs sont passés de Util à Option. Le module Options aspiwack
devient Flags. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@10348 85f007b7-540e-0410-9357-904b9bb8a0f7
2007-12-05Factorisation des opérations sur le type option de Util dans un module aspiwack
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
