2008-11-09More factorization of inductive/record and typeclasses: move classmsozeau
declaration code to toplevel/record, including support for singleton classes as definitions. Parsing code also factorized. Arnaud: one more thing to think about when refactoring the definitions in vernacentries. Add support for specifying what to do with anonymous variables in contexts during internalisation (fixes bug #1982), current choice is to generate a name for typeclass bindings. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@11563 85f007b7-540e-0410-9357-904b9bb8a0f7

2008-11-05Nouvelle syntaxe pour écrire des records (co)inductifs :aspiwack
CoInductive stream (A:Type) := { hd : A ; tl : stream A }. Inductive nelist (A:Type) := { hd : A ; tl : option (nelist A) }. L'affichage n'est pas encore poli. Il reste à choisir l'exact destin de la syntaxe qui était apparue dans la 8.2beta pour les records coinductifs (qui consistait à utiliser "Record" au lieu de "CoInductive" comme maintenant). VernacRecord et VernacInductive semblent maintenant faire doublon, il doit y avoir moyen de les fusionner. Les records mutuellement inductifs restent aussi à faire. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@11539 85f007b7-540e-0410-9357-904b9bb8a0f7
2008-11-05Better extraction renaming phase (fix #1914 plus other non-reported bugs)letouzey
Ocaml : - Fix the Coq__1 that was appearing in a .mli for some functor app in the corresponding .ml (virtual printing of the interface in the .ml + a pp_modname delayed in MTfunsig) - Cleanup in MTwith parts - Better handling of subst for MTsig - Correct push/pop_visible in pp_struct/pp_signature Common : - Merge most of pp_global and pp_module - Clarify the use of tables : remove some of them, attach many others to their corresponding function. - The "visible" table now groups mps, their content, and some subst (for the inside of MTsig) - Cleanup of tables is done via a registration mecanism - No more "initial" create_renamings, instead some fully on-the-fly renaming (thanks to the "Pre" phase) - opened libaries are computed between "Pre" and "Impl" phases - for simplicity, static_clash aren't computed statically anymore (cost?) Extract_env: - A "Pre" phase not only for Ocaml - Extraction Library is in fact also Recursive (for getting a right mpfiles_content) ... but only last item is printed to a real file instead of /dev/null Modutil: No more struct_get_references_* Util : fix the evaluation order of prlist_strict git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@11538 85f007b7-540e-0410-9357-904b9bb8a0f7
2008-10-26Fixes and refinements regarding occurrence selection:herbelin
- make the modifiers "value of" and "type of" for "set" working (it was not!), - clear unselected hypotheses in the "in" clause of "induction/destruct" when the destructed term is a variable (experimental), - support for generalization of hypotheses in the induction hypotheses using the "in" clause of "induction" (e.g. "induction n in m, H" will generalize over m -- would it be better to have an explicit "over"/"generalizing" clause ?). Added clause "as" to "apply in". git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@11509 85f007b7-540e-0410-9357-904b9bb8a0f7

2008-10-23Open notation for declaring record instances.msozeau
It solves feature request 1852, makes me and Arnaud happy and will permit to factor some more code in typeclasses. - Records are introduced using the syntax "{| x := t; y := foo |}" and "with" clauses are currently parsed but not yet supported in the elaboration. You are invited to suggest other syntaxes :) - Missing fields are turned into holes, extra fields cause an error message. The current implementation finds the type of the record at pretyping time, from the typing constraint alone (and just expects an inductive with one constructor). It is then impossible to use scope information to parse the bodies: that may be wrong. The other solution I see is using the fields to detect the type earlier, before internalisation of the bodies, but then we get in name clash hell. - In funind/contrib/interface I mostly put [assert false] everywhere to avoid warnings. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@11496 85f007b7-540e-0410-9357-904b9bb8a0f7
2008-10-23Generalized implementation of generalization.msozeau
- New constr_expr construct [CGeneralization of loc * binding_kind * abstraction_kind option * constr_expr] to generalize the free vars of the [constr_expr], binding these using [binding_kind] and making a lambda or a pi (or deciding from the scope) using [abstraction_kind option] (abstraction_kind = AbsLambda | AbsPi) - Concrete syntax "`( a = 0 )" for explicit binding of [a] and "`{ ... }" for implicit bindings (both "..(" and "_(" seem much more difficult to implement). Subject to discussion! A few examples added in a test-suite file. - Also add missing syntax for implicit/explicit combinations for _binders_: "{( )}" means implicit for the generalized (outer) vars, explicit for the (inner) variable itself. Subject to discussion as well :) - Factor much typeclass instance declaration code. We now just have to force generalization of the term after the : in instance declarations. One more step to using Instance for records. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@11495 85f007b7-540e-0410-9357-904b9bb8a0f7

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

2008-09-02Initial implementation of a new command to define (dependent) functions bymsozeau
equations. It is essentially an implementation of the "Eliminating Dependent Pattern-Matching" paper by Goguen, McBride and McKinna, relying on the new dependent eliminations tactics. The bulk is in contrib/subtac/equations.ml4. It implements a tree splitting on a set of clauses and the generation of a corresponding proof term along with some obligations at each splitting node. The obligations are solved by driving the dependent elimination tactic and you get a complete proof term at the end with the code given by the equations at the right spots, the rest of the cases being pruned automatically. Does not support recursion yet, a file with examples is in the test-suite. With recursion, it would be similar to Agda 2's pattern matching, except it won't reduce in Coq due to JMeq's/K. Incidentally, the simplification tactics after dependent elimination have been improved, resulting in a clearer and more space efficient implementation. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@11352 85f007b7-540e-0410-9357-904b9bb8a0f7
