* No more states/initial.coq, instead coqtop now requires Prelude.voGravatar letouzey2012-08-23
| | | | | | | | For starting a bare coqtop, the recommended option is now "-noinit" that skips the load of Prelude.vo. Option "-nois" is kept for compatibility, it is now an alias to "-noinit". git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@15753 85f007b7-540e-0410-9357-904b9bb8a0f7

* isolate instances about Permutation and PermutationA which may slow rewriteGravatar letouzey2012-07-10
| | | | | | | | | | | | After discovering a rewrite in Ergo that takes a loooong time due to a bad interaction with the instances of Permutation and PermutationA : - PermutationA is now in a separate file SetoidPermutation - File Permutation.v isn't Require'd by SetoidList anymore nor MergeSort.v, just the definitions in Sorted.v - Attempt to put a priority on these instances. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@15584 85f007b7-540e-0410-9357-904b9bb8a0f7
* 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 tauto "special" behavior on singleton types w/ 2 parameters (bug #2680).Gravatar herbelin2012-04-15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | - tauto/intuition now works uniformly on and, prod, or, sum, False, Empty_set, unit, True (and isomorphic copies of them), iff, ->, and on all inhabited singleton types with a no-arguments constructor such as "eq t t" (even though the last case goes out of propositional logic: this features is so often used that it is difficult to come back on it). - New dtauto and dintuition works on all inductive types with one constructors and no real arguments (for instance, they work on records such as "Equivalence"), in addition to -> and eq-like types. - Moreover, both of them no longer unfold inner negations (this is a souce of incompatibility for intuition and evaluation of the level of incompatibility on contribs still needs to be done). Incidentally, and amazingly, fixing bug #2680 made that constants InfA_compat and InfA_eqA in SetoidList.v lost one argument: old tauto had indeed destructed a section hypothesis "@StrictOrder A ltA@ thinking it was a conjunction, making this section hypothesis artificially necessary while it was not. Renouncing to the unfolding of inner negations made auto/eauto sometimes succeeding more, sometimes succeeding less. There is by the way a (standard) problem with not in auto/eauto: even when given as an "unfold hint", it works only in goals, not in hypotheses, so that auto is not able to solve something like "forall P, (forall x, ~ P x) -> P 0 -> False". Should we automatically add a lemma of type "HYPS -> A -> False" in the hint database everytime a lemma ""HYPS -> ~A" is declared (and "unfold not" is a hint), and similarly for all unfold hints? At this occasion, also re-did some proofs of Znumtheory. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@15180 85f007b7-540e-0410-9357-904b9bb8a0f7
* MSetRBT : implementation of MSets via Red-Black treesGravatar letouzey2012-04-13
| | | | | | | | | | | | | | | | | | | Initial contribution by Andrew Appel, many ulterior modifications by myself. Interest: red-black trees maintain logarithmic depths as AVL, but they do not rely on integer height annotations as AVL, allowing interesting performance when computing in Coq or after standard extraction. More on this topic in the article by A. Appel. The common parts of MSetAVL and MSetRBT are shared in a new file MSetGenTree which include the definition of tree and functions such as mem fold elements compare subset. Note that the height of AVL trees is now the first arg of the Node constructor instead of the last one. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@15168 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
