* A slightly more efficient test of well-typedness of restriction ofGravatar herbelin2013-02-21
| | | | | | | | | | | | | | | evars (though this might be slighty more costly). This incidentally solves Appel's part of bug #2830 even though a conceptual problem around the interaction of unification with the proof engine has to be solved. Indeed, what to do when unification, called as part of a tactic, solves or refines the current goal by side effect. Somehow, unifyTerms or tclEVARS should take this possibility into consideration, either by forbidding the refinement of the current goal by side effect, or by acknowledging this refinement by producing new subgoals. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@16232 85f007b7-540e-0410-9357-904b9bb8a0f7

* Dir_path --> DirPathGravatar letouzey2013-02-19
| | | | | | | | Ok, this is merely a matter of taste, but up to now the usage in Coq is rather to use capital letters instead of _ in the names of inner modules. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@16221 85f007b7-540e-0410-9357-904b9bb8a0f7
* Classops : avoid some use of GmapGravatar letouzey2013-02-19
| | | | | | | | | | | | Gmap uses Pervasives.compare which may interact badly with structures like pairs of kernel names For the moment, we consider elements in classes and coercions only according to their user kernel name: this provides maximal compatibility. But it could be interesting to try using comparision according to canonical kernel names... git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@16218 85f007b7-540e-0410-9357-904b9bb8a0f7

* Displaying environment and unfolding aliases in "cannot_unify"Gravatar herbelin2013-02-17
| | | | | | | | | | | | error. Maybe displaying environment is making output overly verbose, but this can also be considered an IDE issue, which would e.g. provide a button to hide/display environment of the error message... Also added some "make_all_name_different" which should probably prevent some anomalies "index to an anonymous variable" at error reporting time. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@16208 85f007b7-540e-0410-9357-904b9bb8a0f7
* A more informative message when the elimination predicate forGravatar herbelin2013-02-17
| | | | | | | | | | | | destruct, rewrite, etc. is not well-typed. Also added support for a more informative message when the elimination predicate is not well-formed while using the smart "second-order" unification algorithm. However the "abstract_list_all" algorithm seems to remain more informative though, so we still use this algorithm for reporting about ill-typed predicates. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@16207 85f007b7-540e-0410-9357-904b9bb8a0f7

| | | | | | | | | | | - In the maybeflex/rigid (lambda) case, try eta if the maybeflex doesn't actually unfold (e.g. vars, or the transparent state says it's opaque). - In the flexible/rigid(lambda) case, try eta if miller-pfenning fails (as the stack might not be a purely applicative one). This will zip the flexible term (a case construct most likely) and try eta expansion on it. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@16134 85f007b7-540e-0410-9357-904b9bb8a0f7
