* Include can accept both Module and Module TypeGravatar letouzey2010-01-07
| | | | | | | | Syntax Include Type is still active, but deprecated, and triggers a warning. The syntax M <+ M' <+ M'', which performs internally an Include, also benefits from this: M, M', M'' can be independantly modules or module type. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@12640 85f007b7-540e-0410-9357-904b9bb8a0f7

* No more specific syntax "Include Self" for inclusion of partially-applied ↵Gravatar letouzey2009-12-07
| | | | | | | | | | | | | | | | | | | functors For Module F(X:SIG), making now a Include F will try to find the X fields in the current context, just as was doing earlier Include Self F. This specific syntax is removed, freeing the keyword "Self". Anyway, with the use of the syntax "<+" there was already hardly any need for syntax "Include Self". Idem for Include Type. Beware that a typo such as "Include F" instead of "Include F G" will produce a different message now, about a missing field instead of a not-enough-applied functor. By the way, some code clean-up and factorisation of inner recursive functions in declaremods.ml. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@12566 85f007b7-540e-0410-9357-904b9bb8a0f7

| | | | | | | | | | | | Fixed some bugs in -beautify and robustness of {struct} clause. Note: I tried to make the Automatic Introduction mode on by default for version >= 8.3 but it is to complicated to adapt even in the standard library. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@12546 85f007b7-540e-0410-9357-904b9bb8a0f7
* Module subtyping : allow many <: and module type declaration with <:Gravatar letouzey2009-11-18
| | | | | | | | | | Any place where <: was legal can now contain many <: declarations. Moreover we can say that the module type we are declaring is a subtype of an earlier module type. See DecidableType2 for examples. Also try to handle correctly the freeze/unfreeze summaries when simulating start/include/end (syntax ... := ... <+ ...) git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@12532 85f007b7-540e-0410-9357-904b9bb8a0f7
* New syntax <+ for chains of Include (or Include Type) (or Include Self (Type))Gravatar letouzey2009-11-16
| | | | | | | | | | | | | | | | | | | | "Module M (...) := M1 <+ M2 <+ M3 <+ ..." is now a shortcut for "Module M (...). Include M1. Include M2. Include M3... End M." Moreover M2,M3,etc can be functors as long as they find what they need in what comes before them (see new command "Include Self"). The only real constraint is that M1,M2,M3,... should not have common elements (for the moment (?)). Same behavior for signature : Module Type M := M1 <+ M2 <+ M3. Note that this <+ is _not_ a primitive construct of the module language, for instance it cannot be used in signature (Module M <: M1 <+ M2 is illegal for the moment). Some example of use in Decidable2 and NZAxioms git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@12530 85f007b7-540e-0410-9357-904b9bb8a0f7

* 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

| | | | | | | | | | | | | - 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
* Move Record desugaring to constrintern and add ability to use notationsGravatar msozeau2008-11-05
| | | | | | | | | for record fields (using "someproj : sometype where not := constr" syntax). Only one notation allowed currently and no redeclaration after the record declaration either (will be done for typeclasses). git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@11542 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
* Generalized implementation of generalization.Gravatar msozeau2008-10-23
| | | | | | | | | | | | | | | | | | | | | - 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).

* 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
* Improvements on coqdoc by adding more information into .globGravatar msozeau2008-05-30

Next step is to test and debug it on bigger developments. On the side: - Fix Program Let which was adding a Global definition. - Correct implicits for well-founded Program Fixpoints. - Add new [Method] declaration kind. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@11024 85f007b7-540e-0410-9357-904b9bb8a0f7

| | | | | | | | | | | | | | | | | | | name after internalisation, to get the correct behavior with typeclass binders. This simplifies the pretty printing and translation of the recursive argument name in various places too. Use this opportunity to factorize the different internalization and interpretation functions of binders as well. This definitely fixes part 2 of bug #1846 and makes it possible to use fixpoint definitions with typeclass arguments in program too, with an example given in EquivDec. At the same time, one fix and one enhancement in Program: - fix a de Bruijn bug in subtac_cases - introduce locations of obligations and use them in case the obligation tactic raises a failure when tried on a particular obligation, as suggested by Sean Wilson. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@10889 85f007b7-540e-0410-9357-904b9bb8a0f7

| | | | | | | | | | | | | | | | | | [in I] := t [return pred] in b", just as SSReflect does with let:. Change implementation: no longer a separate AST node, just add a case_style annotation on Cases to indicate it (if ML was dependently typed we could ensure that LetPatternStyle Cases have only one term to be matched and one branch, alas...). This factors out most code and we lose no functionality (win ! win !). Add LetPat.v test suite. - Slight improvement of inference of return clauses for dependent pattern matching. If matching a variable of non-dependent type under a tycon that mentions it while giving no return clause, the dependency will be automatically infered. Examples at the end of DepPat.

* Essai de changement de sémantique du %scope : Gravatar herbelin2006-10-05
| | | | | | | | | | | | | | | | 1- ne s'applique plus que sur la notation immédiate au lieu de s'appliquer récursivement pour toutes les notations de l'expression concernée; 2- désactive la pile de scope pour cette notation immédiate. Le point 2 est clairement préférable pour les notations de la forme 3%sc, où on ne veut pas que 3 soit interprété dans un autre scope que sc même si sc n'a pas de notations numériques. Le point 1 est plus discutable et risque aussi de poser des incompatibilité (mais le comportement récursif peut être rétabli en changeant la valeur de quelques booléens marqués "recursive" dans constrextern.ml, constrintern.ml, et notation.ml). git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@9208 85f007b7-540e-0410-9357-904b9bb8a0f7

* The "clean integration of subtac" patch.Gravatar msozeau2006-05-29
| | | | | | | | | | | | | Adds a new kind of casts (CastCoerce) for coercing an object to its base type (e.g. inductive). The new cast_type type subsumes usual casts ConvCasts. Much of the patch is just adding ConvCasts where needed. The Pretyping module has been adapted to this change, although it doesn't change anything yet, but this construct could have a use with current coercions also. Pretyping is also cleaned from the "Use type constraints under lambdas" patch which is not yet ready for wide use. It has been transferred to a copy of the Pretyping Functor in subtac_pretyping_F.ml. Subtac is now working as well as I demonstrated at TYPES. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@8875 85f007b7-540e-0410-9357-904b9bb8a0f7

* Si un fixpoint a plusieurs arguments, mais un seul de type inductif, Gravatar letouzey2006-04-14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ce patch dispense d'ecrire le { struct .. } En pratique, dans Topconstr.fixpoint_expr et Rawterm.fix_kind, l'index de l'argument inductif devient un int option au lieu d'un int. Les deux cas possibles: - Some n : les situations autorisées auparavant, a savoir {struct} explicite, ou bien un seul argument au total - None : le cas nouveau, qui redonne un entier lors du passage de rawconstr à constr si l'on trouve effectivement un unique argument ayant un type inductif, et une erreur sinon. Pour l'instant, on cherche l'inductif dans le type de manière syntaxique, mais il est jouable de rajouter un poil de reduction (au moins delta). Dans le détail, voici les coins que ce patch influence: - parsing/g_xml.ml4: continue pour l'instant a attendre un index explicite via un element xml "recIndex" - contrib/interface/xlate.ml: a priori ca marche, car il y avait déjà un cas ctv_ID_OPT_NONE correspondant à l'absence de struct. Par contre, dans le détail, le code pour un CFix utilise l'index de recurrence pour recouper au besoin le type du fixpoint en deux. Est-ce que je me gourre en supposant que si l'on a besoin de couper ainsi ce type, c'est qu'il provient non pas du parseur Coq, mais de l'impression d'un constr, et donc que l'index aura été correctement résolu ? - contrib/subtac/subtac_command.ml: - contrib/funind/indfun.ml: dans les deux cas, j'ai fait le service minimum, le struct reste obligatoire s'il y a plusieurs arguments. Mais ca ne serait pas dur à adapter pour ceux qui comprennent ces parties. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@8718 85f007b7-540e-0410-9357-904b9bb8a0f7
