* - Cleaning phase of the interfaces of libnames.ml and nametab.mlGravatar herbelin2009-08-06
| | | | | | | | | | | | | | | (uniformisation of function names, classification). One of the most visible change is the renaming of section_path into full_path (the use of name section was obsolete due to the module system, but I don't know if the new name is the best chosen one - especially it remains some "sp" here and there). - Simplification of the interface of classify_object (first argument dropped). - Simplification of the code for vernac keyword "End". - Other small cleaning or dead code removal. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@12265 85f007b7-540e-0410-9357-904b9bb8a0f7
* Added "etransitivity".Gravatar herbelin2009-08-03
| | | | | | | | | | | | Added support for "injection" and "discriminate" on JMeq. Seized the opportunity to update coqlib.ml and to rely more on it for finding the equality lemmas. Fixed typos in coqcompat.ml. Propagated symmetry convert_concl fix to transitivity (see 11521). git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@12259 85f007b7-540e-0410-9357-904b9bb8a0f7

* Reactivation of pattern unification of evars in apply unification, inGravatar herbelin2009-07-08
| | | | | | | | | | | | agreement with wish #2117 (pattern unification of evars remained deactivated for 3 years because of incompatibilities with eauto [see commit 9234]; thanks to unification flags, it can be activated for apply w/o changing eauto). Also add test for bug #2123 (see commit 12228). git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@12229 85f007b7-540e-0410-9357-904b9bb8a0f7

* A try at using sort variables during unification. Instead of refreshingGravatar msozeau2009-05-23
| | | | | | | | | | | | | universes as usual, we add the new universes to the sort constraints and do unification modulo those ([constr_unify_with_sorts]): this allows to instanciate Type i with Prop for example and keep track of it. The sort constraints are thrown away at the end of unification for the moment, but we can detect inconsistencies during unification. Make unification more symmetric as well w.r.t. substitution of defined metas. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@12137 85f007b7-540e-0410-9357-904b9bb8a0f7

* Minor unification changes:Gravatar msozeau2009-05-18
| | | | | | | | | | | | | - Primitive setup for firing typeclass resolution on-demand: add a flag to control resolution of remaining evars (e.g. typeclasses) during unification. - Prevent canonical projection resolution when no delta is allowed during unification (fixes incompatibility found in ssreflect). - Correctly check types when the head is an evar _or_ a meta in w_unify. Move [isEvar_or_Meta] to kernel/term.ml, it's used in two places now. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@12131 85f007b7-540e-0410-9357-904b9bb8a0f7

* Many changes in the Makefile infrastructure + a beginning of ocamlbuildGravatar letouzey2009-03-20
| | | | | | | | | | | | | | | | | | | | | | | | * generalize the use of .mllib to build all cma, not only in plugins/ * the .mllib in plugins/ now mention Bruno's new _mod.ml files * lots of .cmo enumerations in Makefile.common are removed, since they are now in .mllib * the list of .cmo/.cmi can be retreive via a shell script line, see for instance rule install-library * Tolink.core_objs and Tolink.ide now contains ocaml _modules_, not _files_ * a -I option to coqdep_boot allows to control piority of includes (some files with the same names in kernel and checker ...) This is quite a lot of changes, you know who to blame / report to if something breaks. ... and last but not least I've started playing with ocamlbuild. The myocamlbuild.ml is far from complete now, but it already allows to build coqtop.{opt,byte} here. See comments at the top of myocamlbuild.ml, and don't hesitate to contribute, either for completing or simplifying it ! git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@12002 85f007b7-540e-0410-9357-904b9bb8a0f7
* Cleaning/improving the use of the "in" clause (e.g. "unfold foo in H at 4"Gravatar herbelin2009-03-16
| | | | | | | | | | | | | | now works correctly, "unfold foo at 4 in H at 3" now fails correctly, etc.). The terminology for clauses (though I don't find the term "clause" very intuitive after all) is mostly preserved except for "simple_clause" which becomes a light form of "clause" instead of being an atom of clause (what played the role of "simple_clause" is now called "goal_location" - better names are welcome). Main changes are in tacticals.ml and tactics.ml. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@11981 85f007b7-540e-0410-9357-904b9bb8a0f7

* 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

* About "apply in":Gravatar herbelin2008-12-09
| | | | | | | | | | | | | | | | | | - 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

Added clause "as" to "apply in". git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@11509 85f007b7-540e-0410-9357-904b9bb8a0f7

Aussi, discriminate sans argument essaie maintenant toutes les hyps quantifiées (au lieu de traiter seulement les buts t1<>t2). --This line, and those below, will be ignored-- M doc/refman/RefMan-tac.tex M CHANGES M pretyping/evd.ml M pretyping/termops.ml M pretyping/termops.mli M pretyping/clenv.ml M tactics/extratactics.ml4 M tactics/inv.ml M tactics/equality.ml M tactics/tactics.mli M tactics/equality.mli M tactics/tacticals.ml M tactics/eqdecide.ml4 M tactics/tacinterp.ml M tactics/tactics.ml M tactics/extratactics.mli M toplevel/auto_ind_decl.ml M contrib/funind/invfun.ml M test-suite/success/Discriminate.v M test-suite/success/Injection.v M proofs/clenvtac.mli M proofs/clenvtac.ml git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@11159 85f007b7-540e-0410-9357-904b9bb8a0f7
* Add possibility to match on defined hypotheses, using brackets toGravatar msozeau2008-06-16
| | | | | | | | | | | | | | disambiguate syntax: [ H := [ ?x ] : context C [ foo ] |- _ ] is ok, as well as [ H := ?x : nat |- _ ] or [H := foo |- _ ], but [ H := ?x : context C [ foo ] ] will not parse. Add applicative contexts in tactics match, to be able to match arbitrary partial applications, e.g.: match f 0 1 2 with appcontext C [ f ?x ] => ... end will bind C to [ ∙ 1 2 ] and x to 0.

* - Officialisation de la notation "pattern c at -1" (cf wish 1798 sur coq-bugs)Gravatar herbelin2008-06-10
| | | | | | | | | | | | | | | - Changement au passage de la convention "at -n1 ... -n2" en "at - n1 ... n2" qui me paraît plus clair à partir du moment où on peut pas mélanger des positifs et des négatifs. - Au passage: - simplification de gclause avec fusion de onconcl et concl_occs, - généralisation de l'utilisation de la désignation des occurrences par la négative aux cas de setoid_rewrite, clrewrite et rewrite at, - correction d'un bug de "rewrite in at" qui utilisait le at de la conclusion dans les hyps. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@11094 85f007b7-540e-0410-9357-904b9bb8a0f7
* - Extension de "generalize" en "generalize c as id at occs".Gravatar herbelin2008-06-08
| | | | | | | | | | | | | | | | | - Ajout clause "in" à "remember" (et passage du code en ML). - Ajout clause "in" à "induction"/"destruct" qui, en ce cas, ajoute aussi une égalité pour se souvenir du terme sur lequel l'induction ou l'analyse de cas s'applique. - Ajout "pose t as id" en standard (Matthieu: j'ai enlevé celui de Programs qui avait la sémantique de "pose proof" tandis que le nouveau a la même sémantique que "pose (id:=t)"). - Un peu de réorganisation, uniformisation de noms dans Arith, et ajout EqNat dans Arith. - Documentation tactiques et notations de tactiques. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@11072 85f007b7-540e-0410-9357-904b9bb8a0f7
