* Improving abbreviations/notations + backtrack of semantic change in r12439Gravatar herbelin2009-11-11
| | | | | | | | | | | | | | | | | | | | | | | | | | - Deactivation of short names registration and printing for abbreviations to identical names, what avoids printing uselessly qualified names binding where the short name is in fact equivalent. - New treatment of abbreviations to names: don't insert any maximally inserted implicit arguments at all at the time of the abbreviation and use the regular internalization strategy to have them inserted at use time. - The previous modifications altogether make redirections of qualified names easier and avoid the semantic change of r12349 and hence allows to keep "Notation b := @a" as it was before, i.e. as a notation for the deactivation of the implicit arguments of a. - Took benefit of these changes and updated nil/cons/list/app redefinition in "List.v". - Fixed parsing/printing notation bugs (loop on partially applied abreviations for constructors in constrintern.ml + bad reverting of notations with holes that captured non anonymous variables in match_cases_pattern). - Add support for parsing/printing abbreviations to @-like constructors and for reverting printing for abbreviations to constructors applied to parameters only (function extern_symbol_pattern). - Minor error messages fixes and minor APIs cleaning. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@12494 85f007b7-540e-0410-9357-904b9bb8a0f7

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | - Cleaning and uniformisation in command.ml: - For better modularity and better visibility, two files got isolated out of command.ml: - lemmas.ml is about starting and saving a proof - indschemes.ml is about declaring inductive schemes - Decomposition of the functions of command.ml into a functional part and the imperative part - Inductive schemes: - New architecture in ind_tables.ml for registering scheme builders, and for sharing and generating on demand inductive schemes - Adding new automatically generated equality schemes (file eqschemes.ml) - "_congr" for equality types (completing here commit 12273) - "_rew_forward" (similar to vernac-level eq_rect_r), "_rew_forward_dep", "_rew_backward" (similar to eq_rect), "_rew_backward_dep" for rewriting schemes (warning, rew_forward_dep cannot be stated following the standard Coq pattern for inductive types: "t=u" cannot be the last argument of the scheme) - "_case", "_case_nodep", "_case_dep" for case analysis schemes - Preliminary step towards discriminate and injection working on any equality-like type (e.g. eq_true) - Restating JMeq_congr under the canonical form of congruence schemes - Renamed "Set Equality Scheme" into "Set Equality Schemes" - Added "Set Rewriting Schemes", "Set Case Analysis Schemes" - Activation of the automatic generation of boolean equality lemmas - Partial debug and error messages improvements for the generation of boolean equality and decidable equality - Added schemes for making dependent rewrite working (unfortunately with not a fully satisfactory design - see file eqschemes.ml) - Some names of ML function made more regular (see dev/doc/changes.txt) - Incidentally, added a flush to obsolete Local/Global syntax warning git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@12481 85f007b7-540e-0410-9357-904b9bb8a0f7

* Integrate a few improvements on typeclasses and Program from the equations ↵Gravatar msozeau2009-10-28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | branch and remove equations stuff which moves to a separate plugin. Classes: - Ability to define classes post-hoc from constants or inductive types. - Correctly rebuild the hint database associated to local hypotheses when they are changed by a [Hint Extern] in typeclass resolution. Tactics and proofs: - Change [revert] so that it keeps let-ins (but not [generalize]). - Various improvements to the [generalize_eqs] tactic to make it more robust and produce the smallest proof terms possible. Move [specialize_hypothesis] in tactics.ml as it goes hand in hand with [generalize_eqs]. - A few new general purpose tactics in Program.Tactics like [revert_until] - Make transitive closure well-foundedness proofs transparent. - More uniform testing for metas/evars in pretyping/unification.ml (might introduce a few changes in the contribs). Program: - Better sorting of dependencies in obligations. - Ability to start a Program definition from just a type and no obligations, automatically adding an obligation for this type. - In compilation of Program's well-founded definitions, make the functional a separate definition for easier reasoning. - Add a hint database for every Program populated by [Hint Unfold]s for every defined obligation constant. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@12440 85f007b7-540e-0410-9357-904b9bb8a0f7

* This big commit addresses two problems:Gravatar soubiran2009-10-21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 1- Management of the name-space in a modular development / sharing of non-logical objects. 2- Performance of atomic module operations (adding a module to the environment, subtyping ...). 1- There are 3 module constructions which derive equalities on fields from a module to another: Let P be a module path and foo a field of P Module M := P. Module M. Include P. ... End M. Declare Module K : S with Module M := P. In this 3 cases we don't want to be bothered by the duplication of names. Of course, M.foo delta reduce to P.foo but many non-logical features of coq do not work modulo conversion (they use eq_constr or constr_pat object). To engender a transparent name-space (ie using P.foo or M.foo is the same thing) we quotient the name-space by the equivalence relation on names induced by the 3 constructions above. To implement this, the types constant and mutual_inductive are now couples of kernel_names. The first projection correspond to the name used by the user and the second projection to the canonical name, for example the internal name of M.foo is (M.foo,P.foo). So: ************************************************************************************* * Use the eq_(con,mind,constructor,gr,egr...) function and not = on names values * ************************************************************************************* Map and Set indexed on names are ordered on user name for the kernel side and on canonical name outside. Thus we have sharing of notation, hints... for free (also for a posteriori declaration of them, ex: a notation on M.foo will be avaible on P.foo). If you want to use this, use the appropriate compare function defined in name.ml or libnames.ml. 2- No more time explosion (i hoppe) when using modules i have re-implemented atomic module operations so that they are all linear in the size of the module. We also have no more unique identifier (internal module names) for modules, it is now based on a section_path like mechanism => we have less substitutions to perform at require, module closing and subtyping but we pre-compute more information hence if we instanciate several functors then we have bigger vo. Last thing, the checker will not work well on vo(s) that contains one of the 3 constructions above, i will work on it soon... git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@12406 85f007b7-540e-0410-9357-904b9bb8a0f7

* MSets: a new generation of FSetsGravatar letouzey2009-10-13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Same global ideas (in particular the use of modules/functors), but: - frequent use of Type Classes inside interfaces/implementation. For instance, no more eq_refl/eq_sym/eq_trans, but Equivalence. A class StrictOrder for lt in OrderedType. Extensive use of Proper and rewrite. - now that rewrite is mature, we write specifications of set operators via iff instead of many separate requirements based on ->. For instance add_spec : In y (add x s) <-> E.eq y x \/ In x s. Old-style specs are available in the functor Facts. - compare is now a pure function (t -> t -> comparison) instead of returning a dependent type Compare. - The "Raw" functors (the ones dealing with e.g. list with no sortedness proofs yet, but morally sorted when operating on them) are given proper interfaces and a generic functor allows to obtain a regular set implementation out of a "raw" one. The last two points allow to manipulate set objects that are completely free of proof-parts if one wants to. Later proofs will rely on type-classes instance search mechanism. No need to emphasis the fact that this new version is severely incompatible with the earlier one. I've no precise ideas yet on how allowing an easy transition (functors ?). For the moment, these new Sets are placed alongside the old ones, in directory MSets (M for Modular, to constrast with forthcoming CSets, see below). A few files exist currently in version foo.v and foo2.v, I'll try to merge them without breaking things. Old FSets will probably move to a contrib later. Still to be done: - adapt FMap in the same way - integrate misc stuff like multisets or the map function - CSets, i.e. Sets based on Type Classes : Integration of code contributed by S. Lescuyer is on the way. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@12384 85f007b7-540e-0410-9357-904b9bb8a0f7
