2009-09-18- Fixed a bug in checking that implicit arguments are all correctlyherbelin
instantiated in tactics (here apply and apply in) that should not open existential goals (see Bas Spitters' coq-club mail about "exists" leaving open existentials). - Preserved the history of the evars occurring in bindings. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@12345 85f007b7-540e-0410-9357-904b9bb8a0f7

2009-08-13Death of "survive_module" and "survive_section" (the first one washerbelin
only used to allow a module to be ended before the summaries were restored what can be solved by moving upwards the place where the summaries are restored). git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@12275 85f007b7-540e-0410-9357-904b9bb8a0f7
2009-08-06- Cleaning phase of the interfaces of libnames.ml and nametab.mlherbelin
(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
2009-08-03Added "etransitivity".herbelin
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
2009-07-15- Fixing bug #2139 (kernel-based test of well-formation of eliminationherbelin
predicate called from proof refiner was failing because it was not aware of evars instantiation; I added a nf_evar in 8.2 branch but for the trunk, I propose to remove the elimination predicate well-formation test; we therefore assume that tactics build correct elimination predicates in Case, is it not too much demanding?). - Seized the opportunity to remove dead kernel code about non dependent elimination predicates (all predicates are stored dependent by default since a few years now). - Anecdotic complement to commit 12229 (removal of obsolete comment). git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@12241 85f007b7-540e-0410-9357-904b9bb8a0f7
2009-07-08Reactivation of pattern unification of evars in apply unification, inherbelin
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
2009-07-07Jolification : tentative de supprimer les "( evd)" et associés quiaspiwack
traînaient un peu partout dans le code depuis la fusion d'evar_map et evar_defs. Début du travail d'uniformisation des noms donnés aux evar_defs à travers le code. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@12224 85f007b7-540e-0410-9357-904b9bb8a0f7
2009-06-11Use a lazy value for the message in FailError, so that it won't bemsozeau
unnecessarily computed when the user won't see it (avoids the costly nf_evar_defs in typeclass errors). Add hook support for mutual definitions in Program.

2009-06-06Fixing bug 2110 (tactic "refine" was calling (co)mutual_fix with index 0herbelin
instead of the index required by the user; extended FixRule and Cofix accordingly). git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@12168 85f007b7-540e-0410-9357-904b9bb8a0f7
2009-06-02Backtrack on experimental unification with sort variables: it requires msozeau
major changes in [w_unify] and the conversion functions used by it to handle the sort constraints correctly. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@12159 85f007b7-540e-0410-9357-904b9bb8a0f7
2009-05-23A try at using sort variables during unification. Instead of refreshingmsozeau
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
2009-05-20- Fixing declarative mode in presence of high use of Change_evars nodesherbelin
(bug 2092 and decl_mode.v in test suite). - Added a debugging printer for pftreestate. - Fixing American spelling in RefMan-decl.tex. - Optimizing application of tactic validation by removing consistency test in descend. - Fixing printing ambiguity for Hint Rewrite ->/<- in extratactics.ml4. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@12134 85f007b7-540e-0410-9357-904b9bb8a0f7
2009-05-18Minor unification changes:msozeau
- 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

2009-03-20Many changes in the Makefile infrastructure + a beginning of ocamlbuildletouzey
* 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
2009-03-16Cleaning/improving the use of the "in" clause (e.g. "unfold foo in H at 4"herbelin
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

2009-02-19On remplace evar_map par evar_defs (seul evar_defs est désormais exporté aspiwack
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

2009-01-18Backporting from v8.2 to trunk:herbelin
- Filtering of doc compilation messages (11793,11795,11796). - Fixing bug #1925 and cleaning around bug #1894 (11796, 11801). - Adding some tests. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@11802 85f007b7-540e-0410-9357-904b9bb8a0f7
2009-01-04Fixed bugs #2001 (search_guard was overwriting the guard index givenherbelin

2008-12-29- Added support for subterm matching in SearchAbout.herbelin
- Backtrack on precise unfolding of "iff" in "tauto": it has effects on the naming of hypotheses (especially when doing "case H" with H of type "{x|P<->Q}" since not unfolding will eventually introduce a name "i" while unfolding will eventually introduce a name "a" (deep sigh). - Miscellaneous (error when a plugin is missing, doc hnf, standardization of names manipulating type constr_pattern, ...). git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@11725 85f007b7-540e-0410-9357-904b9bb8a0f7

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

2008-10-26Fixes 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

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
2008-06-16Add possibility to match on defined hypotheses, using brackets tomsozeau
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.
