* Fixing alpha-conversion bug #2723 introduced in r12485-12486.Gravatar herbelin2012-03-20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The optimisation done of Namegen.visibly_occur_id did not preserve the previous behavior when pr_constr/constr_extern/detype were called on a term with free rel variables. We backtrack on it to go back to the 8.2 behavior. Seized this opportunity to clarify the meaning of the at_top flag in constrextern.ml and printer.ml and to rename it into goal_concl_style. The badly-named at_top flag was introduced in Coq 6.3 in 1999 to mean that when printing variables bound in the goal, names had to avoid the names of the variables of the goal context, so as to keep naming stable when using "intro"; in r4458, printing improved by not avoiding names that were short names of global definitions, e.g. "S", or "O" (except when the at_top flag was on for compatibility reasons). Other printing strategies could be possible in the non-goal-concl-style mode. For instance, all bound variables could be made distinct in a given expression, even if no clash occur, therefore following so-called Barendregt's convention. This could be done by setting "avoid" to "ids_of_rel_context (rel_context env)" in extern_constr and extern_type (and then, Namegen.visibly_occur_id could be re-simplified again!). git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@15067 85f007b7-540e-0410-9357-904b9bb8a0f7

* Try to fix the behavior of clenv_missing used when declaring hintsGravatar letouzey2011-02-22
| | | | | | | | | | | | | Before this patch, hints such as "Hint Resolve -> a" in success/Hints.v were erroneously considered "eauto-only". We try to clarify the big boolean expression via "if", and for the moment we remove the detection of "nonlinearity" via duplicated_metas : on the example, some nonlinearity was found for strange reason (beta expansion ?), and after some discussion with Hugo, it is unclear whether this nonlinearity stuff is useful at all.

* Clenv.connect_clenv without its Evd.foldGravatar letouzey2010-12-15
| | | | | | | | | | | Apparently, it seems that clenv.evd is either created from dummy_goal (in (e)auto) or from a copy of gls (in class_tactics). I've checked experimentally by some assert that on the stdlib the defined part of clenv.evd is always included in gls. I hence propose to simplify this function connect_clenv. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@13718 85f007b7-540e-0410-9357-904b9bb8a0f7

* In the computation of missing arguments for apply, accept that theGravatar herbelin2010-09-17
| | | | | | | | | | | | | | user either gives all missing arguments not dependent in the concl or all missing arguments not *recursively* dependent in the concl (as introduced by commit 13367). In practice, this means that "apply f_equal with A" remains allowed even though the new, recursive, analysis detects that all arguments of f_equal are inferable, including the first type argument (which is inferable from the knowledge of the function). Sized the opportunity to better explain the behavior of clenv_dependent. Also made minor code simplification. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@13426 85f007b7-540e-0410-9357-904b9bb8a0f7

* Removed an evar_merge in clenv_fchain which not only is incorrect butGravatar herbelin2010-05-10
| | | | | | | | | | | | | | | | | | | | | | | | | | | is an important cause of inefficiency when the number of evars is large. It is wrong in the sense that it assumes the two sigma given to clenv_fchain to be disjoint. This is true for metas, but not for evars. It used to be useful in some respect when clenv bindings were represented by open_constr, each of them having private evars (see r10151 which introduced this evar_merge), but determining what evars were private which and were shared is hopeless. Since the removal of private sigmas in r12603, evars in clenv bindings are assumed to be extended monotonically and clenv_fchain should only have to take the most recent evars - assumed to be the first argument - instead of a union. The function clenv_fchain remains anyway fragile since it is asymmetric. More should be done to clean it up so that it receives only one - unambiguous - evars argument, what would mean actually, receiving only one clausenv and the second argument being just a template pair (t:T). The call to evar_merge was source of inefficiency. On some calls to omega in contrib JordanCurveTheorem, removing it reduces the execution time by a factor larger than 5 (from 400s down to 70s on my Core 2 Duo). git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@13007 85f007b7-540e-0410-9357-904b9bb8a0f7

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
