2009-01-01- Fixed bug #2021 (uncaught exception with injection/discriminate whenherbelin
the inductive status of a projectable position comes from a dependency). - Improved doc of the stdlib chapter (see bug #2018), and fixed tex bugs introduced in r11725. - Applied wish #2012 (max_dec transparent). git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@11728 85f007b7-540e-0410-9357-904b9bb8a0f7
2008-12-26- Optimized "auto decomp" which had a (presumably) exponential inherbelin

2008-12-19Nettoyage des variables Coq et amélioration de coqmktop. Lesnotin
principaux changements sont: - coqtop (et coqc) maintenant insensible aux variables d'environnement COQTOP, COQBIN et COQLIB; le chemin vers les librairies Coq peut être spécifié par l'option -coqlib - coqmktop prend 4 nouvelles options: -boot, -coqlib, -camlbin et -camlp4bin; en mode boot, coqmktop se réfère à Coq_config pour les chemins des exécutables OCaml; en dehors du mode boot, coqmktop cherche les exécutables OCaml dans PATH - installation des *.cmxs *.o et *.a en plus des *.cm[ioxa]; ceux-ci étant installé en copiant l'architecture des sources (ie lib.cmxa est installé dans COQLIB/lib/lib.cmxa) - coq_makefile prend maintenant 3 paramètres sous forme de variables d'environnement: COQBIN pour dire où trouver les exécutables Coq, CAMLBIN et CAMLP4BIN pour les exécutables OCaml et Camlp4/5; les chemins vers les librairies sont déduits en utilisant -where Le tout a testé avec Ssreflect (cf coq-contribs) en essayant de simuler les conditions de la vie réelle (Ocaml pas dans le PATH, installation binaire relocalisée, ...). git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@11707 85f007b7-540e-0410-9357-904b9bb8a0f7
2008-12-16Finish fix for the treatment of [inverse] in [setoid_rewrite], making amsozeau
variant of the [unify] tactic that takes a hint db as argument and does unification modulo its [transparent_state].

2008-12-09About "apply in":herbelin
- Added "simple apply in" (cf wish 1917) + conversion and descent under conjunction + contraction of useless beta-redex in "apply in" + support for open terms. - Did not solve the "problem" that "apply in" generates a let-in which is type-checked using a kernel conversion in the opposite side of what the proof indicated (hence leading to a potential unexpected penalty at Qed time). - When applyng a sequence of lemmas, it would have been nice to allow temporary evars as intermediate steps but this was too long to implement. Smoother API in tactics.mli for assert_by/assert_as/pose_proof. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@11662 85f007b7-540e-0410-9357-904b9bb8a0f7

2008-12-02Miscellaneous fixes and improvements:herbelin

2008-11-07Slight change of the semantics of user-given casts: they don't reallymsozeau
help the type _checking_ anymore (they don't become typing constraints) but they permit to coerce a subterm in a type. In particular, when using a VM cast we avoid unneeded, unexpected conversions using the default machine (oops!). Also remove the corresponding comment in pretyping and fix the wrong use of casts in toplevel/command: accept the trouble of using evars. This has the somewhat adverse effect that when typing casted object we now have no typing constraints (see e.g. examples in Cases.v)! Probably, this will be backtracked partially tomorrow as many contribs can rely on it and the change could make some unifications fail (in particular with deep coercions). Let's try anyway! git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@11558 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

2008-10-19Retour en arrière pour raison de compatibilité sur la suppression du nf_evar herbelin
dans clos_norm_flags (cf échec dans CoRN.Transc.InvTrigonom.Tan_ilim). Ceci dit : - cela ne me parait pas moral que clos_norm_flags s'occupe de normaliser les evars, - mais comme "evar" n'est pas un flag supporté par closure.ml, on ne peut pas le donner à la demande comme argument de clos_norm_flags (question: pourrait-on faire supporter la réduction Evar par closure.ml ??). Plus généralement, il y a un problème avec la propagation des instantiations des evars à travers les buts (cf lemme eapply_evar dans test-suite/success/apply.v). git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@11470 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
