| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | capturing bound names unexpectingly). We moved renaming to after finding bindings, i.e. in pretyping "fun x y => x + y" in an ltac environment where y is ltac-bound to x, we type the body in environment "x y |-" but build "fun y y => Rel 2 + Rel 1" (which later on is displayed into "fun y y0 => y + y0"). We renounced to renaming in "match" patterns, which was anyway not working well, as e.g. in let x := ipattern:y in (forall z, match z with S x => x | x => x end = 0). which was producing forall z : nat, match z with 0 => z | S y => y end = 0 because the names in default branches are treated specifically. It would be easy to support renaming in match again, by putting the ltac env in the Cases.pattern_matching_problem state and to rename the names in "typs" (from build_branch), just before returning them at the end of the function (and similarly in abstract_predicate for the names occurring in the return predicate). However, we rename binders in fix which were not interpreted. There are some difficulties with evar because we want them defined in the interpreted env (see comment to ltac_interp_name_env). fix ltac name

If this is too complicated to enforce, we might eventually consider another approach to the question of interpreting patterns in general. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@13428 85f007b7-540e-0410-9357-904b9bb8a0f7
* Improving a few error messages in Ltac interpretationGravatar herbelin2010-09-11
| | | | | | | | | | - improving error message when a reference to unfold is not found - repairing anomaly when an evaluable reference exists at internalisation-time but not at run time, and similarly for an arbitrary term (but the latter is new from 8.3 because of the new use of retyping instead of understand for typing Ltac values) git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@13408 85f007b7-540e-0410-9357-904b9bb8a0f7

* Added support for Ltac-matching terms with variables bound in the patternGravatar herbelin2010-06-06
| | | | | | | | | | | | | | | | | | - Instances found by matching.ml now collect the set of bound variables they possibly depend on in the pattern (see type Pattern.extended_patvar_map); the variables names are canonically ordered so that non-linear matching takes actual names into account. - Removed typing of matching constr instances in advance (in tacinterp.ml) and did it only at use time (in pretyping.ml). Drawback is that we may have to re-type several times the same term but it is necessary for considering terms with locally bound variables of which we do not keep the type (and if even we had kept the type, we would have to adjust the indices to the actual context the term occurs). - A bit of documentation of pattern.mli, matching.mli and pretyping.mli. - Incidentally add env while printing idtac messages. It seems more correct and I hope I did not break some intended existing behavior. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@13080 85f007b7-540e-0410-9357-904b9bb8a0f7

Par exemple, dans Ltac is := let rec i := match goal with |- ?A -> ?B => intro; i | _ => idtac end in i. l'évaluation de i est paresseuse, alors que dans une version non récursive Ltac is := let i := match goal with |- ?A -> ?B => intro | _ => idtac end in i. l'évaluation de i est forte (et échoue sur le "match" qui n'est pas autorisé à retourner une tactique).
