* Improvements in typeclasses eauto and generalized rewriting:Gravatar msozeau2009-05-05
| | | | | | | | | | | | | - Decorate proof search with depth/subgoal number information - Add a tactic [autoapply foo using hints] to call the resolution tactic with the [transparent_state] associated with a hint db, giving better control over unfolding. - Fix a bug in the Lambda case in the new rewrite - More work on the [Proper] and [subrelation] hints to cut the search space while retaining completeness. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@12118 85f007b7-540e-0410-9357-904b9bb8a0f7

* Rewrite of setoid_rewrite to modularize it based on proof-producingGravatar msozeau2009-04-13
| | | | | | | | | | | | | | | strategies (à la ELAN). Now setoid_rewrite is just one strategy and autorewrite is a more elaborate one. Any kind of traversals can be defined, strategies can be composed etc... in ML. An incomplete (no fix) language extension for specifying them in Ltac is there too. On a typical autorewrite-with-setoids usage, proof production time is divided by 2 and proof size by 10.

* Rewrite of Program Fixpoint to overcome the previous limitations: Gravatar msozeau2009-03-28
| | | | | | | | | | | | | | | - The measure can now refer to all the formal arguments - The recursive calls can make all the arguments vary as well - Generalized to any relation and measure (new syntax {measure m on R}) This relies on an automatic curryfication transformation, the real fixpoint combinator is working on a sigma type of the arguments. Reduces to the previous impl in case only one argument is involved. The patch also introduces a new flag on implicit arguments that says if the argument has to be infered (default) or can be turned into a subgoal/obligation. Comes with a test-suite file. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@12030 85f007b7-540e-0410-9357-904b9bb8a0f7

* Last changes in type class syntax: Gravatar msozeau2009-01-18
| | | | | | | | | | | | - curly braces mandatory for record class instances - no mention of the unique method for definitional class instances Turning a record or definition into a class is mostly a matter of changing the keywords to 'Class' and 'Instance' now. Documentation reflects these changes, and was checked once more along with setoid_rewrite's and Program's. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@11797 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

The propagation of the evars associated to the lemma is only allowed when the evar flag is on (i.e. for [eapply]), otherwise they should be resolved by the end of the application.

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

Also add [Hint Transparent/Opaque] which parameterize the dnet and the unification flags used by auto/eauto with a particular database. Document all this. Remove [Typeclasses unfold] directives that are no longer needed (everything is unfoldable by default) and move to [Typeclasses Transparent/Opaque] syntax. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@11409 85f007b7-540e-0410-9357-904b9bb8a0f7

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

* Major speed and space improvements in setoid rewrite:Gravatar msozeau2008-08-27
| | | | | | | | | | | | | | | | | | - Avoid using projections for singleton classes. Divides the size of proofs by 2 and simplifies the typechecking as well. - Switch to the new discrimination net implementation for classes, with the current convention that all constants are unfoldable. Users can add "Typeclasses Opaque" declarations make the dnet discriminate more, otherwise it should be entirely backward-compatible. - Fix bug introduced in r11333 in "transitivity" tactic in presence of coercions. Up to 15% gains on setoid-intensive files like Ring_polynom and Field_theory. More importantly, performance should not decrease significantly by adding new Morphism/Setoid declarations. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@11337 85f007b7-540e-0410-9357-904b9bb8a0f7

* - New auto hints for transparency/opacity control, not bound to Gravatar msozeau2008-08-22
| | | | | | | | | | | | | | | syntax yet. Doesn't change the auto/eauto behavior either. - Typeclass resolution now considers everything transparent by default and does it consistently for "open" and closed terms. - Correctly declare singleton classes definition as opaque for proof search. - Add a few initial declarations to make iff, id, compose... opaque - Add definition of dependent signatures for dependent function types and remove corresponding exception code in class_tactics. The instance requires higher-order unification and is not really usable yet. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@11333 85f007b7-540e-0410-9357-904b9bb8a0f7

* Even better test for choosing rewrite or setoid_rewrite.Gravatar msozeau2008-07-26
| | | | | | | | | | | | | | | Now there is a class "SetoidRelation" for registering relations that should always be considered as setoids and never unfolded. Every "Add Relation" command adds an instance and impl,iff are there by default. Now the test is: if there is a SetoidRelation instance, use it ; otherwise, allow unfolding to find an eq or fallback on setoid_rewrite. To avoid searching for SetoidRelation instances repeateadly we check that it is really needed first by unfolding the hyp. Only two scripts relied on the now-forbidden semantics of rewriting by an @eq inside a setoid relation, in Numbers. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@11269 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

* Enhanced discrimination nets implementation, which can now work withGravatar msozeau2008-06-27
| | | | | | | | | | | | | | | | | goals containing existentials and use transparency information on constants (optionally). Only used by the typeclasses eauto engine for now, but could be used for other hint bases easily (just switch a boolean). Had to add a new "creation" hint to be able to set said boolean upon creation of the typeclass_instances hint db. Improve the proof-search algorithm for Morphism, up to 10 seconds gained in e.g. Field_theory, Ring_polynom. Added a morphism declaration for [compose]. One needs to declare more constants as being unfoldable using the [Typeclasses unfold] command so that discrimination is done correctly, but that amounts to only 6 declarations in the standard library. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@11184 85f007b7-540e-0410-9357-904b9bb8a0f7

| | | | | | | | | | | | | | | | | - 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
* Enhancements to coqdoc, better globalization of sections and modules.Gravatar msozeau2008-06-06
| | | | | | | | Minor fix in Morphisms which prevented working with higher-order morphisms and PER relations. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@11065 85f007b7-540e-0410-9357-904b9bb8a0f7
* - Add -unicode flag to coqtop (sets Flags.unicode_syntax). Used toGravatar msozeau2008-05-12
| | | | | | | | | | | | | | | | | | | change the default pretty-printing to use Π, λ instead of forall and fun (and allow "," as well as "=>" for "fun" to be more consistent with the standard forall and exists syntax). Parsing allows theses new forms too, even if not in -unicode, and does not make Π or λ keywords. As usual, criticism and suggestions are welcome :) Not sure what to do about "->"/"→" ? - [setoid_replace by] now uses tactic3() to get the right parsing level for tactics. - Type class [Instance] names are now mandatory. - Document [rewrite at/by] and fix parsing of occs to support their combination. - Backtrack on [Enriching] modifier, now used exclusively in the implementation of implicit arguments. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@10921 85f007b7-540e-0410-9357-904b9bb8a0f7
* - Cleanup parsing of binders, reducing to a single production for allGravatar msozeau2008-05-11
| | | | | | | | | | | | | | binders. - Change syntax of type class instances to better match the usual syntax of lemmas/definitions with name first, then arguments ":" instance. Update theories/Classes accordingly. - Correct globalization of tactic references when doing Ltac :=/::=, update documentation. - Remove the not so useful "(x &)" and "{{x}}" syntaxes from Program.Utils, and subset_scope as well. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@10919 85f007b7-540e-0410-9357-904b9bb8a0f7
