* induction/destruct : nicer syntax for generating equations (solves #2741)Gravatar letouzey2012-07-09
| | | | | | | | | | | | | | | | | | The ugly syntax "destruct x as [ ]_eqn:H" is replaced by: destruct x eqn:H destruct x as [ ] eqn:H Some with induction. Of course, the pattern behind "as" is arbitrary. For an anonymous version, H could be replaced by ?. The old syntax with "_eqn" still works for the moment, by triggers a warning. For making this new syntax work, we had to change the seldom-used "induction x y z using foo" into "induction x, y, z using foo". Now, only one "using" can be used per command instead of one per comma-separated group earlier, but I doubt this will bother anyone. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@15566 85f007b7-540e-0410-9357-904b9bb8a0f7

* Notation: a new annotation "compat 8.x" extending "only parsing"Gravatar letouzey2012-07-05
| | | | | | | | | | | | | | | | | | | | | | Suppose we declare : Notation foo := bar (compat "8.3"). Then each time foo is used in a script : - By default nothing particular happens (for the moment) - But we could get a warning explaining that "foo is bar since coq > 8.3". For that, either use the command-line option -verb-compat-notations or the interactive command "Set Verbose Compat Notations". - There is also a strict mode, where foo is forbidden : the previous warning is now an error. For that, either use the command-line option -no-compat-notations or the interactive command "Unset Compat Notations". When Coq is launched in compatibility mode (via -compat 8.x), using a notation tagged "8.x" will never trigger a warning or error. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@15514 85f007b7-540e-0410-9357-904b9bb8a0f7

* Fixing a few bugs (see #2571) related to interpretation of multiple bindersGravatar herbelin2012-04-06
| | | | | | | | | | | | | | | | | | | | | | | | - 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

| | | | | | | | | | | | | | | | | | | | | | | | Instead of hard-coding in search.ml some substrings such as "_admitted" or "_subproof" we don't want to see in results of SearchAbout and co, we now have a user command: Add Search Blacklist "foo". Remove Search Blacklist "foo". (* the opposite *) Print Table Search Blacklist. (* the current state *) In Prelude.v, three substrings are blacklisted originally: - "_admitted" for internal lemmas due to admit. - "_subproof" for internal lemmas due to abstract. - "Private_" for hiding auxiliary modules not meant for global usage. Note that substrings are searched in the fully qualified names of the available lemmas (e.g. "Coq.Init.Peano.plus"). This commit also adds the prefix "Private_" to some internal modules in Numbers, Z, N, etc. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@14408 85f007b7-540e-0410-9357-904b9bb8a0f7

* Less ambitious application of a notation for eq_rect. We proposedGravatar herbelin2011-08-10
| | | | | | | | | | | | | | | | | | "rewrite Heq in H" but "rewrite" is sometimes used by users and I don't want to have to change their file. The solution to put the notations in a module does not work with name "rewrite" because loading the module would change the status of "rewrite" from simple ident to keyword (and we cannot declare "rewrite" as an ident, as shown in previous commit). Then we come back on notation "rew" (this name is also used by some users), in a module. This continues commit r14366 and r14390 and improves on the level of the notation. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@14400 85f007b7-540e-0410-9357-904b9bb8a0f7

In BinNat/BinPos, for uniformity, compare_antisym is now (y ?= x) = CompOpp (x ?=y) instead of the symmetrical result. In BigN / BigZ, eq_bool is now eqb In BinIntDef, gtb and geb are kept for the moment, but a comment advise to rather use ltb and leb.

* CompareSpec: a slight generalization/reformulation of CompSpecGravatar letouzey2011-03-17
| | | | | | | | | | | | | | | | | | | CompareSpec expects 3 propositions Peq Plt Pgt instead of 2 relations eq lt and 2 points x y. For the moment, we still always use (Peq=eq x y), (Plt=lt x y) (Pgt=lt y x), but this may not be always the case, especially for Pgt. The former CompSpec is now defined in term of CompareSpec. Compatibility is preserved (except maybe a rare unfold or red to break the CompSpec definition). Typically, CompareSpec looks nicer when we have infix notations, e.g. forall x y, CompareSpec (x=y) (x<y) (y<x) (x?=x) while CompSpec is shorter when we directly refer to predicates: forall x y, CompSpec eq lt x y (compare x y) git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@13914 85f007b7-540e-0410-9357-904b9bb8a0f7

We were already almost never boxing definitions anymore in stdlib files. "(Un)Boxed Definition foo" will now trigger a parsing error, same with Fixpoint.
