| | | | | | | | | | | | | - 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

| | | | | | | | | | | | | | | | | | | | | | | inductive types was not taken into account). - Virtually extended tauto to - support arbitrary-length disjunctions and conjunctions, - support arbitrary complex forms of disjunctions and conjunctions when in the contravariant of an implicative hypothesis, - stick with the purely propositional fragment and not apply reflexivity. This is virtual in the sense that it is not activated since it breaks compatibility with the existing tauto. - Modified the notion of conjunction and unit type used in hipattern in a way that is closer to the intuitive meaning (forbid dependencies between parameters in conjunction; forbid indices in unit types). - Investigated how far "iff" could be turned into a direct inductive definition; modified tauto.ml4 so that it works with the current and the alternative definition. - Fixed a bug in the error message from lookup_eliminator. - Other minor changes. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@11721 85f007b7-540e-0410-9357-904b9bb8a0f7

* Generalized binding syntax overhaul: only two new binders: `() and `{},Gravatar msozeau2008-12-14
| | | | | | | | | | | | | | | | | guessing the binding name by default and making all generalized variables implicit. At the same time, continue refactoring of Record/Class/Inductive etc.., getting rid of [VernacRecord] definitively. The AST is not completely satisfying, but leaning towards Record/Class as restrictions of inductive (Arnaud, anyone ?). Now, [Class] declaration bodies are either of the form [meth : type] or [{ meth : type ; ... }], distinguishing singleton "definitional" classes and inductive classes based on records. The constructor syntax is accepted ([meth1 : type1 | meth1 : type2]) but raises an error immediately, as support for defining a class by a general inductive type is not there yet (this is a bugfix!). git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@11679 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

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).

| | | | | | | | | | | | | | | - 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
* Open notation for declaring record instances.Gravatar msozeau2008-10-23
| | | | | | | | | | | | | | | | | | | | 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

| | | | | | | | | | | | | | | | | | | | | - 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
* A much better implementation of implicit generalization:Gravatar msozeau2008-10-22
| | | | | | | | | | | | | - Do it after internalisation (esp. after notation expansion) - Generalize it to any constr, not just typeclasses - Prepare for having settings on the implicit status of generalized variables (currently only impl,impl and expl,expl are supported). - Simplified implementation! (Still some refactoring needed in typeclasses parsing code).

* Add the ability to declare [Hint Extern]'s with no pattern.Gravatar msozeau2008-09-07

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

| | | | | | | | | | | | | | | | | | - Utilisation de notations de type "abbreviation paramétrée" plutôt que de notations introduisant des mots-clés, là où c'est possible (cela affecte QDen, in_left/in_right, inhabited, S/P dans NZCyclic). - Extension du lexeur pour qu'il prenne le plus long token valide au lieu d'échouer sur un plus long préfixe non valide de token (permet notamment de faire passer la notation de Georges "'C_ G ( A )" sans invalider toute séquence commençant par 'C et non suivie de _) - Rajout d'un point final à certains messages d'erreur qui n'en avaient pas. - Ajout String.copy dans string_of_label ("trou" de mutabilité signalé par Georges -- le "trou" lié aux vecteurs des noeuds App restant lui ouvert). git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@11225 85f007b7-540e-0410-9357-904b9bb8a0f7

* - Improve [Context] vernacular to allow arbitrary binders, not justGravatar msozeau2008-07-07
| | | | | | | | | | | | | | | classes, and simplify the implementation. - Experimental syntax {{ cl : Class args }} and (( cl : Class args )) which respectively make cl an implicit or explicit argument ({{ }} is equivalent to [ ]). Could be extended to any type of binder, eg. [Definition flip ((R : relation carrier)) : relation carrier := ...]. The idea behind double brackets is to distinguish macro-binders which perform implicit generalization from regular binders. It could also save [ ] for other uses. - Fix bug #1901 about {} binders in records. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@11210 85f007b7-540e-0410-9357-904b9bb8a0f7
* Fixes in handling of implicit arguments:Gravatar msozeau2008-07-04
| | | | | | | | | | | | | - Now [ id : Class foo ] makes id an explicit argument, and [ Class foo ] is equivalent to [ {someid} : Class foo ]. This makes declarations such as "Class Ord [ eq : Eq a ]" have sensible implicit args. - Better handling of {} in class and record declarations, refactorize code for declaring structures and classes. - Fix merging of implicit arguments information on section closing. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@11204 85f007b7-540e-0410-9357-904b9bb8a0f7
