2010-07-22Simplified the way internalization_data (i.e. bindings of bound varsherbelin
to their signature of implicit positions and scopes) is computed. A bit of documentation in constrintern.mli. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@13315 85f007b7-540e-0410-9357-904b9bb8a0f7
2010-06-30Move [delayed] to util and use [force_delayed] everywhere to forcemsozeau
thunks. Move from [lazy] to [delayed] in subtac. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@13227 85f007b7-540e-0410-9357-904b9bb8a0f7
2010-06-29Made tclABSTRACT normalize evars before saying it does not supportherbelin
them. This was the cause of the failure of compilation of CyclicAxioms after "replace" starting supporting open constrs (r13206). Seized the opportunity to clean a little bit things around nf_evar, whd_evar, check_evars, etc. Removed obsolete printer mod_self_id from dev/db. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@13214 85f007b7-540e-0410-9357-904b9bb8a0f7

2010-03-07Fix treatment of remaining unification constraints: raise a moremsozeau
informative exception if some constraints do not unify. All calls except one used to raise a less informative exception when the constraints weren't solved. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@12849 85f007b7-540e-0410-9357-904b9bb8a0f7

2009-11-27Added support for definition of fixpoints using tactics.herbelin
Fixed some bugs in -beautify and robustness of {struct} clause. Note: I tried to make the Automatic Introduction mode on by default for version >= 8.3 but it is to complicated to adapt even in the standard library. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@12546 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

2009-06-17Fallback on not using [fix_proto] if the right imports aren't there, the msozeau
tactics that use it won't be in scope either. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@12193 85f007b7-540e-0410-9357-904b9bb8a0f7

2009-04-24Backporting 12080 (fixing bug #2091 on bad rollback in the "where"herbelin
clause resulting in stray notations for e.g. variable named "le") and 12083 (fixing bug in as clause of apply in) from trunk. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@12103 85f007b7-540e-0410-9357-904b9bb8a0f7
2009-04-24- New cleaning phase for the entry points of pretyping.mlherbelin
- Uniformisation of ML names between pretyping.ml and subtac_pretyping_F.ml so as to ease the comparison between these files. Application of a change that cannot do harm: j_nf_evar now called after getting evd from consider_remaining_unif_problems in Subtac_pretyping_F.understand_judgment. Four differences remain (is it the sign of a problem?): 1) understand_type fails in Pretyping if evars remain but does not fail in Subtac_pretyping_F 2) resolve_typeclasses (when called) is called with ~onlyargs:false and ~fail:true in Pretyping.understand, Pretyping.understand_gen and Pretyping.understand_type but with true and false in these same functions in Subtac_pretyping_F 3) understand_ltac does not call typeclasses in Pretyping but it does call it in Subtac_pretyping_F 4) understand_judgment does call typeclasses in Pretyping but not in Subtac_pretyping_F git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@12099 85f007b7-540e-0410-9357-904b9bb8a0f7
2009-04-08Experimental support for automatic destruction of recursive calls andmsozeau
clearing of recursive protototypes in Program obligations. Relies on marking said prototypes with a particular constant and preprocessing obligation goals with an appropriate tactic. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@12071 85f007b7-540e-0410-9357-904b9bb8a0f7
2009-04-08Fix bug #2083 for good: verify that the measure and relation aremsozeau
well-formed before doing anything. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@12070 85f007b7-540e-0410-9357-904b9bb8a0f7
2009-03-28Rewrite of Program Fixpoint to overcome the previous limitations: msozeau
- The measure can now refer to all the formal arguments - The recursive calls can make all the arguments vary as well - Generalized to any relation and measure (new syntax {measure m on R}) This relies on an automatic curryfication transformation, the real fixpoint combinator is working on a sigma type of the arguments. Reduces to the previous impl in case only one argument is involved. The patch also introduces a new flag on implicit arguments that says if the argument has to be infered (default) or can be turned into a subgoal/obligation. Comes with a test-suite file. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@12030 85f007b7-540e-0410-9357-904b9bb8a0f7
