2011-11-06Fixing incorrect change to pattern-unification over Meta's introducedherbelin
in r14199 (June 2011). Meta's implicitly depend on the context they are defined in and this has to be taken into account for checking if occurrences are distinct (in particular, no Var's are allowed as arguments of a pattern-unifiable Meta). The example expected to be accepted thanks to r14199 is not a pattern-unification problem (it has more than one solution) and was anyway already accepted (strange). Compared to before r14199, aliases expansion and restriction of pattern unification check to variables occurring in the right-hand side are however now taken into account. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@14642 85f007b7-540e-0410-9357-904b9bb8a0f7

2011-10-22Use full conversion for checking type of holes in destruct over aherbelin
pattern; this fixes stupid causes of failure of destruct shown by compiling contrib Containers. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@14579 85f007b7-540e-0410-9357-904b9bb8a0f7
2011-10-11Completing r14538 (Chung-Kil Hur's trick for fast dependently-typedherbelin
second-order matching) which was not working correctly in the general case. Also made that second-order matching for tactics (abstract_list_all) uses this algorithm, along the lines of a proposal first experimented by Dan Grayson (see unification.v). git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@14549 85f007b7-540e-0410-9357-904b9bb8a0f7
2011-10-05It happens that the type inference algorithm (pretyping) did not checkherbelin
that the return predicate of the match construction is at an allowed sort, resulting in tactics possibly manipulating ill-typed terms. This is now fixed, Incidentally removed in pretyping an ill-placed coercion. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@14508 85f007b7-540e-0410-9357-904b9bb8a0f7

2011-06-18Relaxed the constraint introduced in r14190 that froze the existingherbelin
evars when rewriting. Use it for autorewrite and subst. Accept evars instantiation in multi_rewrite so that rewrite alone remains compatible (it is used in contribs, e.g. Godel, in places where it does not seem absurd to allow it), but there are no good reason for it. Comments welcome. + addition of some tests for rewriting (one being related to commit 14217) git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@14222 85f007b7-540e-0410-9357-904b9bb8a0f7

2011-06-12Added a new flag for freezing evars in tactic unification. Used thisherbelin
flag to forbid rewriting tactics to instantiate an evar of the goal while looking for subterms (this is not clear that we always want that for rewrite but we certainly want it for autorewrite; see comments by Charguéraud on coqdev Oct 2010). In a few cases in the theories, a pre-existing evar of an hyp used for rewriting is instantiated by the rewriting step. Let's accept this at the current time. We have to make progress towards documenting and stabilizing the strategy for matching/unifying subterms in rewrite/induction/set... git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@14190 85f007b7-540e-0410-9357-904b9bb8a0f7

2011-02-22Try to fix the behavior of clenv_missing used when declaring hintsletouzey
Before this patch, hints such as "Hint Resolve -> a" in success/Hints.v were erroneously considered "eauto-only". We try to clarify the big boolean expression via "if", and for the moment we remove the detection of "nonlinearity" via duplicated_metas : on the example, some nonlinearity was found for strange reason (beta expansion ?), and after some discussion with Hugo, it is unclear whether this nonlinearity stuff is useful at all. The next coqbench might provide some answer to this question, we'll see git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@13850 85f007b7-540e-0410-9357-904b9bb8a0f7

2010-11-19SearchAbout: who has never been annoyed by the [ ] syntax ?letouzey
Well, hopefully, that belongs to the past: you should now be able to do the very same queries as before, without typing the [ ]. For instance: SearchAbout plus mult. This removal of [ ] is optional, the old syntax is still legal: - for compatibility reasons - for square bracket lovers - for those that have "inside" or "outside" as legal identifier in their development and want to search about them. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@13654 85f007b7-540e-0410-9357-904b9bb8a0f7
