2012-06-22Added an indirection with respect to Loc in Compat. As many [open Compat]ppedrot
were closed (i.e. the only remaining ones are those of printing/parsing). Meanwhile, a simplified interface is provided in loc.mli. This also permits to put Pp in Clib, because it does not depend on CAMLP4/5 anymore. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@15475 85f007b7-540e-0410-9357-904b9bb8a0f7

2012-06-14Internalization of pattern is done in two phases.pboutill
First Notations, syntactic definitions, primitive entries are tackled to build raw_cases_pattern_expr. Reference are revolved at this time too. Then raw_patterns are internalized as cases_pattern or applied inductive (dealing with implicit args, or_pattern refactoring, aliases). It is more uniform, it allows notations for non fully applied constructors but : - It does not raise a warning when an identifier is also a global_reference different than a constructor. - It looks for implicit arguments twice. (because finding scopes of arguments asks for implicit arguments). - It does not deal anymore with constants that evaluates to constructor. (This one is voluntary, dealing with implicit & notations is already a hell full of bugs so what will be next step ? Any terms that computes to a pattern ???) git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@15439 85f007b7-540e-0410-9357-904b9bb8a0f7

2012-04-06Fixing a few bugs (see #2571) related to interpretation of multiple bindersherbelin
- fixing missing spaces in the format of the exists' notations (Logic.v); - fixing wrong variable name in check_is_hole error message (topconstr.ml); - interpret expressions with open binders such as "forall x y, t" as "forall (x:_) (y:_),t" instead of "forall (x y:_),t" to avoid the "implicit type" of a variable being propagated to the type of another variable of different base name. An open question remains: when writing explicitly "forall (x y:_),t", should the types of x and y be the same or not. To avoid the "bug" that x and y have implicit types but the one of x takes precedences, I enforced the interpretation (in constrintern, not in parsing) that "forall (x y:_),t" means the same as "forall (x:_) (y:_),t". However, another choice could have been made. Then one would have to check that if x and y have implicit types, they are the same; also, glob_constr should ideally be changed to support a GProd and GLam with multiple names in the same type, especially if this type is an evar. On the contrary, one might also want e.g. "forall x y : list _, t" to mean "forall (x:list _) (y:list _), t" with distinct instanciations of "_" ...). git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@15121 85f007b7-540e-0410-9357-904b9bb8a0f7
2012-03-26Slight change in the semantics of arguments scopes: scopes can noherbelin
longer be bound to Funclass or Sortclass (this does not seem to be useful).

2012-03-20Fixing alpha-conversion bug #2723 introduced in r12485-12486.herbelin
The optimisation done of Namegen.visibly_occur_id did not preserve the previous behavior when pr_constr/constr_extern/detype were called on a term with free rel variables. We backtrack on it to go back to the 8.2 behavior. Seized this opportunity to clarify the meaning of the at_top flag in constrextern.ml and printer.ml and to rename it into goal_concl_style. The badly-named at_top flag was introduced in Coq 6.3 in 1999 to mean that when printing variables bound in the goal, names had to avoid the names of the variables of the goal context, so as to keep naming stable when using "intro"; in r4458, printing improved by not avoiding names that were short names of global definitions, e.g. "S", or "O" (except when the at_top flag was on for compatibility reasons). Other printing strategies could be possible in the non-goal-concl-style mode. For instance, all bound variables could be made distinct in a given expression, even if no clash occur, therefore following so-called Barendregt's convention. This could be done by setting "avoid" to "ids_of_rel_context (rel_context env)" in extern_constr and extern_type (and then, Namegen.visibly_occur_id could be re-simplified again!). git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@15067 85f007b7-540e-0410-9357-904b9bb8a0f7
2012-03-20Continuing r15045-15046 and r15055 (fixing bug #2732 about atomicherbelin
tactic arguments of ltac functions). Added support for recursive entries in ARGUMENT EXTEND, for right-hand sides of ARGUMENT EXTEND raising exceptions and for right-hand sides referring to "loc". Also fixed parsing level of initial value in create_arg (raw instead of glob). Thanks to the Ssreflect plugin for revealing these problems. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@15065 85f007b7-540e-0410-9357-904b9bb8a0f7
2012-03-18Fixing bug #2732 (anomaly when using the tolerance for writingherbelin
"f atomic_tac" as a short-hand for "f ltac:(atomic_tac)" for "f" an Ltac function - see Tacinterp.add_primitive_tactic). More precisely, when parsing "f ref" and "ref" is recognized as the name of some TACTIC-EXTEND-defined tactic parsable as an atomic tactic (like "eauto", "firstorder", "discriminate", ...), the code was correct only when a rule of the form `TACTIC EXTEND ... [ "foo" -> ...] END' was given (where "foo" has no arguments in the rule) but not when a rule of the form `TACTIC EXTEND ... [ "foo" tactic_opt(p) -> ...] END' was given (where "foo" had an optional argument in the rule). In particular, "firstorder" was in this case. More generally, if, for an extra argument able to parse the empty string, a rule `TACTIC EXTEND ... [ "foo" my_special_extra_arg(p) -> ...] END' was given, then "foo" was not recognized as parseable as an atomic string (this happened e.g. for "eauto"). This is now also fixed. There was also another bug when the internal name of tactic was not the same as the user-level name of the tactic. This is the reason why "congruence" was not recognized when given as argument of an ltac (its internal name is "cc"). Incidentally removed the redundant last line in the parsing rule for "firstorder". git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@15041 85f007b7-540e-0410-9357-904b9bb8a0f7

2012-01-16Parameters in pattern first step.pboutill
In interp/constrintern.ml, '_' for constructor parameter are required if you use AppExpl ('@Constr') and added in order to be erased at the last time if you do not use '@'. It makes the use of notation in pattern more permissive. For example, -8<------ Inductive I (A: Type) : Type := C : A -> I A. Notation "x <: T" := (C T x) (at level 38). Definition uncast A (x : I A) := match x with | x <: _ => x end. -8<------ was forbidden. Backward compatibility is strictly preserved expect for syntactic definitions: While defining "Notation SOME = @Some", SOME had a special treatment and used to be an alias of Some in pattern. It is now uniformly an alias of @Some ('_' must be provided for parameters). In interp/constrextern.ml, except if all the parameters are implicit and all the arguments explicit (This covers all the cases of the test-suite), pattern are generated with AppExpl (id est '@') (so with '_' for parameters) in order to become compatible in any case with future behavior. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@14909 85f007b7-540e-0410-9357-904b9bb8a0f7
