Util only depends on Ocaml stdlib and Utf8 tables. Generic pretty printing and loc functions are in Pp. Generic errors are in Errors. + Training white-spaces, useless open, prlist copies random erasure. Too many "open Errors" on the contrary. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@15020 85f007b7-540e-0410-9357-904b9bb8a0f7

how the names of an ltac expression are globalized - allowing the expression to be a constr and in some initial context - and when and how this ltac expression is interpreted - now expecting a pure tactic in a different context).

- Many of them were broken, some of them after Pierre B's rework of mli for ocamldoc, but not only (many bad annotation, many files with no svn property about Id, etc) - Useless for those of us that work with git-svn (and a fortiori in a forthcoming git-only setting) - Even in svn, they seem to be of little interest git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@12972 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
