* Add type annotations around all calls to Libobject.declare_objectGravatar letouzey2011-11-02
| | | | | | | | | | | | | | | | | These annotations are purely optional, but could be quite helpful when trying to understand the code, and in particular trying to trace which which data-structure may end in the libobject part of a vo. By the way, we performed some code simplifications : - in Library, a part of the REQUIRE objects was unused. - in Declaremods, we removed some checks that were marked as useless, this allows to slightly simplify the stored objects. To investigate someday : in recordops, the RECMETHODS is storing some evar_maps. This is ok for the moment, but might not be in the future (cf previous commit on auto hints). This RECMETHODS was not detected by my earlier tests : not used in the stdlib ? git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@14627 85f007b7-540e-0410-9357-904b9bb8a0f7

* A tatical "timeout <n> <tac>" that fails if <tac> hasn't finished in <n> secondsGravatar letouzey2011-03-18
| | | | | | | | | | | | | | Note: even if this new tactical can be quite handy during the development phase, (for instance to bound the time allocated to some search tactics), please be aware of its main drawback: with it, scripts are no longer machine-independant, something that works on a quick machine may fail on a slow one. The converse is even possible if you combine this "timeout" with other tactic combinators. We strongly advise to not leave any "timeout" in the final version of a development. In addition, this feature won't probably work on native win32, since Unix.alarm isn't implemented. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@13917 85f007b7-540e-0410-9357-904b9bb8a0f7

* Change of nomenclature: rawconstr -> glob_constrGravatar glondu2010-12-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | There was a discrepancy of the notions "raw" and "globalized" between constrs and tactics, and some confusion of the notions in e.g. genarg.mli (see all globwit_* there). This commit is a first step towards unification of terminology between constrs and tactics. Changes in module names will be done separately. In extraargs.ml4, the "ARGUMENT EXTEND raw" and related stuff, even affected by this change, has not been touched and highlights another confusion in "ARGUMENT EXTEND" in general that will be addressed later. The funind plugin doesn't respect the same naming conventions as the rest, so leave some "raw" there for now... they will be addressed later.

* Made intros_until and onInductionArg a bit stricter and robustGravatar herbelin2010-06-13
| | | | | | | | | | | | | The tolerance for overloading "id" as quantified hypothesis and as declared variable is kept - because induction_arg entry is not available to extended tactics, e.g. "discriminate", and these extensions do not know a priori if a name is quantified or declared. However, an upstream check is done to ensure that an induction argument exists as term if not quantified so that the tactics do not have to check this individually by themselves. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@13125 85f007b7-540e-0410-9357-904b9bb8a0f7

* Added support for Ltac-matching terms with variables bound in the patternGravatar herbelin2010-06-06
| | | | | | | | | | | | | | | | | | - Instances found by matching.ml now collect the set of bound variables they possibly depend on in the pattern (see type Pattern.extended_patvar_map); the variables names are canonically ordered so that non-linear matching takes actual names into account. - Removed typing of matching constr instances in advance (in tacinterp.ml) and did it only at use time (in pretyping.ml). Drawback is that we may have to re-type several times the same term but it is necessary for considering terms with locally bound variables of which we do not keep the type (and if even we had kept the type, we would have to adjust the indices to the actual context the term occurs). - A bit of documentation of pattern.mli, matching.mli and pretyping.mli. - Incidentally add env while printing idtac messages. It seems more correct and I hope I did not break some intended existing behavior. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@13080 85f007b7-540e-0410-9357-904b9bb8a0f7
* Add (almost) compatibility with camlp4, without breaking support for camlp5Gravatar letouzey2010-05-19
| | | | | | | | | | | | | | | | | | | | | | | The choice between camlp4/5 is done during configure with flags -usecamlp5 (default for the moment) vs. -usecamlp4. Currently, to have a full camlp4 compatibility, you need to change all "EXTEND" and "GEXTEND Gram" into "EXTEND Gram", and change "EOI" into "`EOI" in grammar entries. I've a sed script that does that (actually the converse), but I prefer to re-think it and check a few things before branching this sed into the build mechanism. lib/compat.ml4 is heavily used to hide incompatibilities between camlp4/5 and try to propose a common interface (cf LexerSig / GrammarSig). A few incompatible quotations have been turned into underlying code manually, in order to make the IFDEF CAMLP5 THEN ... ELSE ... END parsable by both camlp4 and 5. See in particular the fate of <:str_item< declare ... end >> Stdpp isn't used anymore, but rather Ploc (hidden behind local module Loc). This forces to use camlp5 > 5.01. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@13019 85f007b7-540e-0410-9357-904b9bb8a0f7

Even before Spiwack's new proof engine, some Evd.fold were very costly, e.g. in check_evars or progress_evar_map. With the new proof engine, undefined evars traversals are apparently even more common (at least, it improves significantly the complexity of some calls to omega in JordanCurveTheorem - a new factor 5-7 after the factor 5-6 obtained by removal of evar_merge in clenv_fchain in commit 13007, arriving to figures comparable to the 8.3 ones). git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@13011 85f007b7-540e-0410-9357-904b9bb8a0f7

* Here comes the commit, announced long ago, of the new tactic engine.Gravatar aspiwack2010-04-22

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

In 8.2 branch, it remains fragile (syntaxes that were accepted remain accepted and a message warns if the occurrences coming after the "with" are not taken into account). git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@12614 85f007b7-540e-0410-9357-904b9bb8a0f7
* Safer, though ad hoc, approach to re-interpretation of the argument ofGravatar herbelin2009-12-28
| | | | | | | | | | | | | | | | | | general_multi_multi_rewrite. Due to the option "!" of rewrite, a lemma may need to be interpreted several times with different instances of the implicit arguments. Interpreting the term as a constr in tacinterp.ml would need to either refresh the holes (i.e. the evars) or detype what has been typed and in both cases, complicated things can happen because the evars associated to these holes may have been used in instantiating former evars of the goal. Leaving the term as a rawconstr would need to export the interpretation functions from tacinterp which is technically complicated in the current situation because equality.ml is currently linked before tacinterp. The solution used is to delay the interpretation using an ML closure. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@12610 85f007b7-540e-0410-9357-904b9bb8a0f7

* Opened the possibility to type Ltac patterns but it is not fully functional yetGravatar herbelin2009-12-24
| | | | | | | | | | | | | | | - to type patterns w/o losing the information of what subterm is a hole would need to remember where holes were in "understand", but "understand" needs sometimes to instantiate evars to ensure the type of an evar is not its original type but the type of its instance (what can e.g. lower a universe level); we would need here to update evars type at the same time we define them but this would need in turn to check the convertibility of the actual and expected type since otherwise type-checking constraints may disappear; - typing pattern is apparently expensive in time; is it worth to do it for the benefit of pattern-matching compilation and coercion insertion? git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@12607 85f007b7-540e-0410-9357-904b9bb8a0f7

* Generic support for open terms in tacticsGravatar herbelin2009-12-21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We renounced to distribute evars to constr and bindings and to let tactics do the merge. There are now two disciplines: - the general case is that the holes in tactic arguments are pushed to the general sigma of the goal so that tactics have no such low-level tclEVARS, Evd.merge, or check_evars to do: - what takes tclEVARS and check_evars in charge is now a new tactical of name tclWITHHOLES (this tactical has a flag to support tactics in either the "e"- mode and the non "e"- mode); - the merge of goal evars and holes is now done generically at interpretation time (in tacinterp) and as a side-effect it also anticipates the possibility to refer to evars of the goal in the arguments; - with this approach, we don't need such constr/open_constr or bindings/ebindings variants and we can get rid of all ugly inj_open-style coercions; - some tactics however needs to have the exact subset of holes known; this is the case e.g. of "rewrite !c" which morally reevaluates c at each new rewriting step; this kind of tactics still receive a specific sigma around their arguments and they have to merge evars and call tclWITHHOLES by themselves. Changes so that each specific tactics can take benefit of this generic support remain to be done. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@12603 85f007b7-540e-0410-9357-904b9bb8a0f7
