* 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

* Attempt of fix for extraction of modules typesGravatar letouzey2008-03-05
| | | | | | | | | | | | | | | | | * When no explicit module type is given in Coq, extraction proceeds with more caution when recontructing a module type from the module. For instance, a module ident isn't keep, since it's the name of an implementation, not of a module type. Fix the bug functor M -> M : funsig M -> M instead of funsig M -> typeof(M) * Removed duplicated code with Modops * The call to replicate_msid doesn't seem to be as crucial as before. Let's try to remove it. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@10620 85f007b7-540e-0410-9357-904b9bb8a0f7

* Inversion de l'ordre de chargement des objets logiques et non logiquesGravatar herbelin2006-04-15
| | | | | | | | | | | | | | | | | | | | | à la déclaration des paramètres de foncteurs (problème de synchronisation révélé par bug #1118, apparu suite à l'appel de lookup_mind par load_struct, suite au passage à un discharge local) Les objets non logiques sont maintenant chargés après car ils peuvent dépendre d'objets logiques. Et comme les objets non logiques (p.ex. l'import récursif de modules dans la nametab) sont nécessaires au typage de l'éventuelle contrainte de module, on reporte la gestion de la contrainte au moment du end_module (on aurait peut-être pu faire plus fin et extraire dans do_module la partie purement module, mais après tout le report de la contrainte de type dans le end_module ne semble pas génante). À la date d'aujourd'hui, le bug #1118 reste toutefois ouvert avec les définitions de module non interactives. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@8721 85f007b7-540e-0410-9357-904b9bb8a0f7

* HUGE COMMITGravatar sacerdot2005-01-03
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 1. when applying a functor F(X) := B to a module M, the obtained module is no longer B{X.t := M.t for all t}, but B{X.t := b where b is the body of t in M}. In principle it is now easy to fine tune the behaviour to choose whether b or M.t must be used. This change implies modifications both inside and outside the kernel. 2. for each object in the library it is now necessary to define the behaviour w.r.t. the substitution {X.t := b}. Notice that in many many cases the pre-existing behaviour w.r.t. the substitution {X.t := M.t} was broken (in the sense that it used to break several invariants). This commit fixes the behaviours for most of the objects, excluded a) coercions: a future commit should allow any term to be declared as a coercion; moreover the invariant that just a coercion path exists between two classes will be broken by the instantiation. b) global references when used as arguments of a few tactics/commands In all the other cases the behaviour implemented is the one that looks to me as the one expected by the user (if possible): [ terminology: not expanded (X.t := M.t) vs expanded (X.t := b) ] a) argument scopes: not expanded b) SYNTAXCONSTANT: expanded c) implicit arguments: not expanded d) coercions: expansion to be done (for now not expanded) e) concrete syntax tree for patterns: expanded f) concrete syntax tree for raw terms: expanded g) evaluable references (used by unfold, delta expansion, etc.): not expanded h) auto's hints: expanded when possible (i.e. when the expansion of the head of the pattern is rigid) i) realizers (for program extraction): nothing is done since the actual code does not look for the realizer of definitions with a body; however this solution is fragile. l) syntax and notation: expanded m) structures and canonical structures: an invariant says that no parameter can happear in them ==> the substitution always yelds the original term n) stuff related to V7 syntax: since this part of the code is doomed to disappear, I have made no effort to fix a reasonable semantics; not expanded is the default one applied o) RefArgTypes: to be understood. For now a warning is issued whether expanded != not expanded, and the not expanded solution is chosen. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@6555 85f007b7-540e-0410-9357-904b9bb8a0f7

| | | | | | | | | | | the new module kernel/mod_subst.ml. MOTIVATION: mod_subst is compiled after kernel/term.ml; thus it is now possible to define substitutions that also delta-expand constants (by associating the delta-expanded form to the constant name). git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@6304 85f007b7-540e-0410-9357-904b9bb8a0f7

* Réforme de l'interprétation des termes :Gravatar herbelin2002-11-14
| | | | | | | | | | | | | | | - Le parsing se fait maintenant via "constr_expr" au lieu de "Coqast.t" - "Coqast.t" reste pour l'instant pour le pretty-printing. Un deuxième pretty-printer dans ppconstr.ml est basé sur "constr_expr". - Nouveau répertoire "interp" qui hérite de la partie interprétation qui se trouvait avant dans "parsing" (constrintern.ml remplace astterm.ml; constrextern.ml est l'équivalent de termast.ml pour le nouveau printer; topconstr.ml; contient la définition de "constr_expr"; modintern.ml remplace astmod.ml) - Libnames.reference tend à remplacer Libnames.qualid git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@3235 85f007b7-540e-0410-9357-904b9bb8a0f7
