* 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| | | | | | | | | | | | | | | | According to B. Gregoire, this stuff is obsolete.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

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | - Cleaning and uniformisation in command.ml: - For better modularity and better visibility, two files got isolated out of command.ml: - lemmas.ml is about starting and saving a proof - indschemes.ml is about declaring inductive schemes - Decomposition of the functions of command.ml into a functional part and the imperative part - Inductive schemes: - New architecture in ind_tables.ml for registering scheme builders, and for sharing and generating on demand inductive schemes - Adding new automatically generated equality schemes (file eqschemes.ml) - "_congr" for equality types (completing here commit 12273) - "_rew_forward" (similar to vernac-level eq_rect_r), "_rew_forward_dep", "_rew_backward" (similar to eq_rect), "_rew_backward_dep" for rewriting schemes (warning, rew_forward_dep cannot be stated following the standard Coq pattern for inductive types: "t=u" cannot be the last argument of the scheme) - "_case", "_case_nodep", "_case_dep" for case analysis schemes - Preliminary step towards discriminate and injection working on any equality-like type (e.g. eq_true) - Restating JMeq_congr under the canonical form of congruence schemes - Renamed "Set Equality Scheme" into "Set Equality Schemes" - Added "Set Rewriting Schemes", "Set Case Analysis Schemes" - Activation of the automatic generation of boolean equality lemmas - Partial debug and error messages improvements for the generation of boolean equality and decidable equality - Added schemes for making dependent rewrite working (unfortunately with not a fully satisfactory design - see file eqschemes.ml) - Some names of ML function made more regular (see dev/doc/changes.txt) - Incidentally, added a flush to obsolete Local/Global syntax warning git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@12481 85f007b7-540e-0410-9357-904b9bb8a0f7
* This big commit addresses two problems:Gravatar soubiran2009-10-21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 1- Management of the name-space in a modular development / sharing of non-logical objects. 2- Performance of atomic module operations (adding a module to the environment, subtyping ...). 1- There are 3 module constructions which derive equalities on fields from a module to another: Let P be a module path and foo a field of P Module M := P. Module M. Include P. ... End M. Declare Module K : S with Module M := P. In this 3 cases we don't want to be bothered by the duplication of names. Of course, M.foo delta reduce to P.foo but many non-logical features of coq do not work modulo conversion (they use eq_constr or constr_pat object). To engender a transparent name-space (ie using P.foo or M.foo is the same thing) we quotient the name-space by the equivalence relation on names induced by the 3 constructions above. To implement this, the types constant and mutual_inductive are now couples of kernel_names. The first projection correspond to the name used by the user and the second projection to the canonical name, for example the internal name of M.foo is (M.foo,P.foo). So: ************************************************************************************* * Use the eq_(con,mind,constructor,gr,egr...) function and not = on names values * ************************************************************************************* Map and Set indexed on names are ordered on user name for the kernel side and on canonical name outside. Thus we have sharing of notation, hints... for free (also for a posteriori declaration of them, ex: a notation on M.foo will be avaible on P.foo). If you want to use this, use the appropriate compare function defined in name.ml or libnames.ml. 2- No more time explosion (i hoppe) when using modules i have re-implemented atomic module operations so that they are all linear in the size of the module. We also have no more unique identifier (internal module names) for modules, it is now based on a section_path like mechanism => we have less substitutions to perform at require, module closing and subtyping but we pre-compute more information hence if we instanciate several functors then we have bigger vo. Last thing, the checker will not work well on vo(s) that contains one of the 3 constructions above, i will work on it soon... git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@12406 85f007b7-540e-0410-9357-904b9bb8a0f7

| | | | | | | | | | | | | | 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.

* 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

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Quelques modifications autour (géographiquement) de Util.list_split_at Util.list_split_at devient Util.list_split_when (dénomination inventée arbitrairement par moi-même, mais qui ne devrait pas déranger grand monde vu qu'il semble n'y avoir que deux occurences de cette fonction). Pour laisser la place à la fonction suivante : Introduction de Util.list_split_at: qui sépare la liste à une position donnée (alors que la nouvellement nommé list_split_when sépare à la première occurence "vrai" d'un prédicat). Ajout de quelques commentaires dans util.ml (pas le mli) sur ces deux fonctions. Suppression de Impargs.list_split_at (appel à Util). Suppression de Subtac_pretyping.list_split_at (qui était du code mort de toute façon). Suppression Util.list_split_by qui n'est utilisé nulle part et est une réimplémentation de List.partition (qui est probablement meilleure, en particulier tail-recursive) git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@11851 85f007b7-540e-0410-9357-904b9bb8a0f7

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
