* Fixing a few other inconsistencies with notations.Gravatar Hugo Herbelin2016-10-17
| | | | | `Notation ".a" := nat.' was accepted and used for printing but not recognized in parsing. Now it does. Other examples in test-suite.

* | A heuristic to add parentheses in the presence of rules such asGravatar Hugo Herbelin2016-04-27
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Notation "## c" := (S c) (at level 0, c at level 100). which break the stratification of precedences. This works for the case of infix or suffix operators which occur in only one grammar rule, such as +, *, etc. This solves the "constr" part of #3709, even though this example is artificial. The fix is not complete. It puts extra parenthesese even when it is end of sentence, as in Notation "# c % d" := (c+d) (at level 3). Check fun x => # ## x % ## (x * 2). (* fun x : nat => # ## x % (## x * 2) *) The fix could be improved by not always using 100 for the printing level of "## c", but 100 only when not the end of the sentence. The fix does not solve the general problem with symbols occurring in more than one rule, as e.g. in: Notation "# c % d" := (c+d) (at level 1). Notation "## c" := (S c) (at level 0, c at level 5). Check fun x => # ## x % 0. (* Parentheses are necessary only if "0 % 0" is also parsable *) I don't see in this case what better approach to follow than restarting the parser to check reversibility of the printing.

* 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

* Extension of the recursive notations mechanismGravatar herbelin2010-07-22
| | | | | | | | | | | | | - Added support for recursive notations with binders - Added support for arbitrary large iterators in recursive notations - More checks on the use of variables and improved error messages - Do side-effects in metasyntax only when sure that everything is ok - Documentation Note: it seems there were a small bug in match_alist (instances obtained from matching the first copy of iterator were not propagated). git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@13316 85f007b7-540e-0410-9357-904b9bb8a0f7

* Fixed some printing bugs.Gravatar herbelin2010-04-18
| | | | | | | | | | - Notations with coercions to funclass inserted were not working any longer since r11886. Made a fix but maybe should we eventually type the notations so that they have a canonical form (and in particular with coercions pre-inserted?). - Improved spacing management in printing extra tactic arguments "by" and "in". git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@12951 85f007b7-540e-0410-9357-904b9bb8a0f7
