2012-10-26Change Hint Resolve, Immediate to take a global reference as argumentmsozeau
instead of a general constr: this is the most common case and does not loose generality (one can simply define constrs before Hint Resolving them). Benefits: - Natural semantics for typeclasses, not class resolution needed at Hint Resolve time, meaning less trouble for users as well. - Ability to [Hint Remove] any hint so declared. - Simplifies the implementation as well. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@15930 85f007b7-540e-0410-9357-904b9bb8a0f7

2012-07-09induction/destruct : nicer syntax for generating equations (solves #2741)letouzey
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

2012-07-05Notation: a new annotation "compat 8.x" extending "only parsing"letouzey
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

2012-04-06Fixing a few bugs (see #2571) related to interpretation of multiple bindersherbelin
- 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

2011-08-11SearchAbout and similar: add a customizable blacklistletouzey
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

2011-08-10Less ambitious application of a notation for eq_rect. We proposedherbelin
"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

Start of a uniform treatment of compare, eqb, leb, ltb: - We now ensure that they are provided by N,Z,BigZ,BigN,Nat and Pos - Some generic properties are derived in OrdersFacts.BoolOrderFacts In BinPos, more work about sub_mask with nice implications on compare (e.g. simplier proof of lt_trans). 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.

2011-03-17CompareSpec: a slight generalization/reformulation of CompSpecletouzey
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
2011-01-28Remove the "Boxed" syntaxes and the const_entry_boxed fieldletouzey
According to B. Gregoire, this stuff is obsolete. Fine control on when to launch the VM in conversion problems is now provided by VMcast. We were already almost never boxing definitions anymore in stdlib files. "(Un)Boxed Definition foo" will now trigger a parsing error, same with Fixpoint. The option "(Un)Set Boxed Definitions" aren't there anymore, but tolerated (as no-ops), since unknown options raise a warning instead of an error by default. Some more cleaning could be done in the vm. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@13806 85f007b7-540e-0410-9357-904b9bb8a0f7

2010-04-22Here comes the commit, announced long ago, of the new tactic engine.aspiwack
This is a fairly large commit (around 140 files and 7000 lines of code impacted), it will cause some troubles for sure (I've listed the know regressions below, there is bound to be more). At this state of developpement it brings few features to the user, as the old tactics were ported with no change. Changes are on the side of the developer mostly. Here comes a list of the major changes. I will stay brief, but the code is hopefully well documented so that it is reasonably easy to infer the details from it. Feature developer-side: * Primitives for a "real" refine tactic (generating a goal for each evar). * Abstract type of tactics, goals and proofs * Tactics can act on several goals (formally all the focused goals). An interesting consequence of this is that the tactical (. ; [ . | ... ]) can be separated in two tacticals (. ; .) and ( [ . | ... ] ) (although there is a conflict for this particular syntax). We can also imagine a tactic to reorder the goals. * Possibility for a tactic to pass a value to following tactics (a typical example is an intro function which tells the following tactics which name it introduced). * backtracking primitives for tactics (it is now possible to implement a tactical '+' with (a+b);c equivalent to (a;c+b;c) (itself equivalent to (a;c||b;c)). This is a valuable tool to implement tactics like "auto" without nowing of the implementation of tactics. * A notion of proof modes, which allows to dynamically change the parser for tactics. It is controlled at user level with the keywords Set Default Proof Mode (this is the proof mode which is loaded at the start of each proof) and Proof Mode (switches the proof mode of the current proof) to control them. * A new primitive Evd.fold_undefined which operates like an Evd.fold, except it only goes through the evars whose body is Evar_empty. This is a common operation throughout the code, some of the fold-and-test-if-empty occurences have been replaced by fold_undefined. For now, it is only implemented as a fold-and-test, but we expect to have some optimisations coming some day, as there can be a lot of evars in an evar_map with this new implementation (I've observed a couple of thousands), whereas there are rarely more than a dozen undefined ones. Folding being a linear operation, this might result in a significant speed-up. * The declarative mode has been moved into the plugins. This is made possible by the proof mode feature. I tried to document it so that it can serve as a tutorial for a tactic mode plugin. Features user-side: * Unfocus does not go back to the root of the proof if several Focus-s have been performed. It only goes back to the point where it was last focused. * experimental (non-documented) support of keywords BeginSubproof/EndSubproof: BeginSubproof focuses on first goal, one can unfocus only with EndSubproof, and only if the proof is completed for that goal. * experimental (non-documented) support for bullets ('+', '-' and '*') they act as hierarchical BeginSubproof/EndSubproof: First time one uses '+' (for instance) it focuses on first goal, when the subproof is completed, one can use '+' again which unfocuses and focuses on next first goal. Meanwhile, one cas use '*' (for instance) to focus more deeply. Known regressions: * The xml plugin had some functions related to proof trees. As the structure of proof changed significantly, they do not work anymore. * I do not know how to implement info or show script in this new engine. Actually I don't even know what they were suppose to actually mean in earlier versions either. I wager they would require some calm thinking before going back to work. * Declarative mode not entirely working (in particular proofs by induction need to be restored). * A bug in the inversion tactic (observed in some contributions) * A bug in Program (observed in some contributions) * Minor change in the 'old' type of tactics causing some contributions to fail. * Compilation time takes about 10-15% longer for unknown reasons (I suspect it might be linked to the fact that I don't perform any reduction at QED-s, and also to some linear operations on evar_map-s (see Evd.fold_undefined above)). git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@12961 85f007b7-540e-0410-9357-904b9bb8a0f7
2010-02-17Arith's min and max placed in Peano (+basic specs max_l and co)letouzey
This allow for instance to remove the dependency of List.v toward Min.v To prove max_l and co, we push Le.le_pred and Le.le_S_n into Peano. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@12784 85f007b7-540e-0410-9357-904b9bb8a0f7

2010-02-12CompSpecType, a clone of CompSpec but in Type instead of Propletouzey
In interfaces fields like compare_spec, a CompSpec is prefered to get nice extraction, but then no "destruct (compare_spec .. ..)" is possible in a Type context. Now you can say there "destruct (CompSpec2Type (compare_spec ... ...))" This translate to the Type variant, and make the analysis on it (which is equivalent to analysing the comparison directly). git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@12753 85f007b7-540e-0410-9357-904b9bb8a0f7
