* Proof using ...Gravatar gareuselesinge2011-12-12
| | | | | | | | | | | | | New vernacular "Proof using idlist" to declare the variables to be discharged at the end of the current proof. The system checks that the set of declared variables is a superset of the set of actually used variables. It can be combined in a single line with "Proof with": Proof with .. using ..

* Remove the "Boxed" syntaxes and the const_entry_boxed fieldGravatar letouzey2011-01-28
| | | | | | | | | | | | | | | | According to B. Gregoire, this stuff is obsolete. Fine control on when to launch the VM in conversion problems is now provided by VMcast. We were already almost never boxing definitions anymore in stdlib files. "(Un)Boxed Definition foo" will now trigger a parsing error, same with Fixpoint. The option "(Un)Set Boxed Definitions" aren't there anymore, but tolerated (as no-ops), since unknown options raise a warning instead of an error by default. Some more cleaning could be done in the vm. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@13806 85f007b7-540e-0410-9357-904b9bb8a0f7

* Remove the svn-specific $Id$ annotationsGravatar letouzey2010-04-29
| | | | | | | | | | | - Many of them were broken, some of them after Pierre B's rework of mli for ocamldoc, but not only (many bad annotation, many files with no svn property about Id, etc) - Useless for those of us that work with git-svn (and a fortiori in a forthcoming git-only setting) - Even in svn, they seem to be of little interest git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@12972 85f007b7-540e-0410-9357-904b9bb8a0f7

* Integrate a few improvements on typeclasses and Program from the equations ↵Gravatar msozeau2009-10-28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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

* - Cleaning phase of the interfaces of libnames.ml and nametab.mlGravatar herbelin2009-08-06
| | | | | | | | | | | | | | | (uniformisation of function names, classification). One of the most visible change is the renaming of section_path into full_path (the use of name section was obsolete due to the module system, but I don't know if the new name is the best chosen one - especially it remains some "sp" here and there). - Simplification of the interface of classify_object (first argument dropped). - Simplification of the code for vernac keyword "End". - Other small cleaning or dead code removal. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@12265 85f007b7-540e-0410-9357-904b9bb8a0f7
* Improved parameterization of Coq:Gravatar herbelin2009-08-02
| | | | | | | | | | | | | | | - add coqtop option "-compat X.Y" so as to provide compatibility with previous versions of Coq (of course, this requires to take care of providing flags for controlling changes of behaviors!), - add support for option names made of an arbitrary length of words (instead of one, two or three words only), - add options for recovering 8.2 behavior for discriminate, tauto, evar unification ("Set Tactic Evars Pattern Unification", "Set Discriminate Introduction", "Set Intuition Iff Unfolding"). Update of .gitignore git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@12258 85f007b7-540e-0410-9357-904b9bb8a0f7
* Backtrack sur la mémoïsation de nf_evar.Gravatar aspiwack2009-03-04
| | | | | | | | | | | | | | | | L'expérience prouve que ce n'est pas franchement concluant. On peut se risquer à une explication : - nf_evar, version mémoïsée n'est pas tail recursive - On retarde la substitution des hypothèses de l'evar en échange de faire moins de substitutions d'evars. Intuitivement c'est intéressant seulement si il y a plus de substitutions d'evar dupliquées que d'hypothèses dupliquées. Ce qui ne doit pas être le cas (ne serait-ce que parce que dupliquer une evar duplique aussi ses variables libres).

* 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
* DISCLAIMERGravatar puech2009-01-17
========== This big patch is commited here with a HUGE experimental tag on it. It is probably not a finished job. The aim of committing it now, as agreed with Hugo, is to get some feedback from potential users to identify more clearly the directions the implementation could take. So please feel free to mail me any remarks, bug reports or advices at <puech@cs.unibo.it>. Here are the changes induced by it : For the user ============ * Search tools have been reimplemented to be faster and more general. Affected are [SearchPattern], [SearchRewrite] and [Search] (not [SearchAbout] yet). Changes are: - All of them accept general constructions, and previous syntactical limitations are abolished. In particular, one can for example [SearchPattern (nat -> Prop)], which will find [isSucc], but also [le], [gt] etc. - Patterns are typed. This means that you cannot search mistyped expressions anymore. I'm not sure if it's a good or a bad thing though (especially regarding coercions)... * New tool to automatically infer (some) Record/Typeclasses instances. Usage : [Record/Class *Infer* X := ...] flags a record/class as subject to instance search. There is also an option to activate/deactivate the search [Set/Unset Autoinstance]. It works by finding combinations of definitions (actually all kinds of objects) which forms a record instance, possibly parameterized. It is activated at two moments: - A complete search is done when defining a new record, to find all possible instances that could have been formed with past definitions. Example: Require Import List. Record Infer Monoid A (op:A->A->A) e := { assoc : forall x y z, op x (op y z) = op (op x y) z; idl : forall x, x = op x e ; idr : forall x, x = op e x }. new instance Monoid_autoinstance_1 : (Monoid nat plus 0) [...] - At each new declaration (Definition, Axiom, Inductive), a search is made to find instances involving the new object. Example: Parameter app_nil_beg : forall A (l:list A), l = nil ++ l. new instance Build_Monoid_autoinstance_12 : (forall H : Type, Monoid (list H) app nil) := (fun H : Type => Build_Monoid (list H) app nil ass_app (app_nil_beg H) (app_nil_end H)) For the developper ================== * New yet-to-be-named datastructure in [lib/dnet.ml]. Should do efficient one-to-many or many-to-one non-linear first-order filtering, faster than traditional methods like discrimination nets (so yes, the name of the file should probably be changed). * Comes with its application to Coq's terms [pretyping/term_dnet.ml]. Terms are represented so that you can search for patterns under products as fast as you would do not under products, and facilities are provided to express other kind of searches (head of application, under equality, whatever you need that can be expressed as a pattern) * A global repository of all objects defined and imported is maintained [toplevel/libtypes.ml], with all search facilities described before. * A certain kind of proof search in [toplevel/autoinstance.ml]. For the moment it is specialized on finding instances, but it should be generalizable and reusable (more on this in a few months :-). The bad news ============ * Compile time should increase by 0 to 15% (depending on the size of the Requires done). This could be optimized greatly by not performing substitutions on modules which are not functors I think. There may also be some inefficiency sources left in my code though... * Vo's also gain a little bit of weight (20%). That's inevitable if I wanted to store the big datastructure of objects, but could also be optimized some more. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@11794 85f007b7-540e-0410-9357-904b9bb8a0f7
