- prise en compte du niveau à la déclaration du type comme une fonction des sortes des conclusions des paramètres uniformes - suppression du retypage de chaque instance de type inductif (trop coûteux) et donc abandon de l'idée de calculer une sorte minimale même dans des cas comme Inductive t (b:bool) := c : (if b then Prop else Type) -> t. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@8845 85f007b7-540e-0410-9357-904b9bb8a0f7

2005-01-171. added code to handle the inclusion of inductive types and constructors insacerdot
parameters. 2. however, the code is still not working if the parameters are referenced later on in the module signature. To fix this the representation of terms must be changed to unify references to constants, inductive types and constructors. 3. thus the code above is prefixed by an error that suggest to the user how to avoid the problem right now. Note: the above code has not been commented out to keep it in synch with the other changes in the kernel. However, it is dead code for now. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@6600 85f007b7-540e-0410-9357-904b9bb8a0f7
2005-01-03HUGE COMMITsacerdot
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
2004-11-16Names.substitution (and related functions) and Term.subst_mps moved tosacerdot
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
2004-11-16IMPORTANT COMMIT: constant is now an ADT (it used to be equal to kernel_name).sacerdot
MOVITATION: in a forthcoming commit the application of a substitution to a constant will return a constr and not a constant. The application of a substitution to a kernel_name will return a kernel_name. Thus "constant" should be use as a kernel name for references that can be delta-expanded. KNOWN PROBLEMS: the only problem faced is in pretyping/recordops.ml (the code that implements "Canonical Structure"s). The ADT is violated once in this ocaml module. My feeling is that the implementation of "Canonical Structure"s should be rewritten to avoid this situation. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@6303 85f007b7-540e-0410-9357-904b9bb8a0f7
