2018-10-10[coqlib] Rebindable Coqlib namespace.Emilio Jesus Gallego Arias
We refactor the `Coqlib` API to locate objects over a namespace `module.object.property`. This introduces the vernacular command `Register g as n` to expose the Coq constant `g` under the name `n` (through the `register_ref` function). The constant can then be dynamically located using the `lib_ref` function.

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 This is a common operation throughout the code, some of the fold-and-test-if-empty occurences have been replaced by fold_undefined.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

2009-10-28Integrate a few improvements on typeclasses and Program from the equations ↵msozeau
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

2008-09-02Initial implementation of a new command to define (dependent) functions bymsozeau
equations. It is essentially an implementation of the "Eliminating Dependent Pattern-Matching" paper by Goguen, McBride and McKinna, relying on the new dependent eliminations tactics. The bulk is in contrib/subtac/equations.ml4. It implements a tree splitting on a set of clauses and the generation of a corresponding proof term along with some obligations at each splitting node. The obligations are solved by driving the dependent elimination tactic and you get a complete proof term at the end with the code given by the equations at the right spots, the rest of the cases being pruned automatically. Does not support recursion yet, a file with examples is in the test-suite. With recursion, it would be similar to Agda 2's pattern matching, except it won't reduce in Coq due to JMeq's/K. Incidentally, the simplification tactics after dependent elimination have been improved, resulting in a clearer and more space efficient implementation. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@11352 85f007b7-540e-0410-9357-904b9bb8a0f7

2008-03-28Improve error handling and messages for typeclasses. msozeau
Add definitions of relational algebra in Classes/RelationClasses including equivalence, inclusion, conjunction and disjunction. Add PartialOrder class and show that we have a partial order on relations. Change SubRelation to subrelation for consistency with the standard library. The caracterization of PartialOrder is a bit original: we require an equivalence and a preorder so that the equivalence relation is equivalent to the conjunction of the order relation and its inverse. We can derive antisymmetry and appropriate morphism instances from this. Also add a fully general heterogeneous definition of respectful from which we can build the non-dependent respectful combinator. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@10728 85f007b7-540e-0410-9357-904b9bb8a0f7
