2010-01-11Support "Local Obligation Tactic" (now the default in sections).msozeau
Update Numbers that was implicitely using [simpl_relation] instead of the default tactic [program_simpl]. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@12647 85f007b7-540e-0410-9357-904b9bb8a0f7

2009-12-24Opened the possibility to type Ltac patterns but it is not fully functional yetherbelin
- 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
2009-12-21Generic support for open terms in tacticsherbelin
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

2009-11-08Restructuration of command.ml + generic infrastructure for inductive schemesherbelin
- 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

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

2009-10-21This big commit addresses two problems:soubiran
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

2009-08-06- Cleaning phase of the interfaces of libnames.ml and nametab.mlherbelin
(uniformisation of function names, classification). One of the most visible change is the renaming of section_path into full_path (the use of name section was obsolete due to the module system, but I don't know if the new name is the best chosen one - especially it remains some "sp" here and there). - Simplification of the interface of classify_object (first argument dropped). - Simplification of the code for vernac keyword "End". - Other small cleaning or dead code removal. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@12265 85f007b7-540e-0410-9357-904b9bb8a0f7

2009-04-08Some dead code removal + cleanupsletouzey
This commit concerns about the first half of the useless code mentionned by Oug for coqtop (without plugins). For the moment, Oug is used in a mode where any elements mentionned in a .mli is considered to be precious. This already allows to detect and remove about 600 lines, and more is still to come. Among the interesting points, the type Entries.specification_entry and its constructors SPExxx were never used. Large parts of cases.ml (and hence subtac_cases.ml) were also useless. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@12069 85f007b7-540e-0410-9357-904b9bb8a0f7

Reduces to the previous impl in case only one argument is involved.
