2013-05-09A uniformization step around understand_* and interp_* functions.herbelin
- Clarification of the existence of three algorithms for solving unconstrained evars: - the type-class mechanism - the heuristics for solving pending conversion problems and multi-candidates - Declare Implicit Tactic (when called from tactics) Main function for solving unconstrained evars (when not using understand): Pretyping.solve_remaining_evars - Clarification of the existence of three corresponding kinds of errors when reporting about unsolved evars: Main function for checking resolution of evars independently of the understand functions: Pretyping.check_evars_are_solved - Introduction of inference flags in pretyping for governing which combination of the algorithms to use when calling some understand function; there is also a flag of expanding or not evars and for requiring or not the resolution of all evars - Less hackish way of managing Pretyping.type_constraint: all three different possibilities are now represented by three different constructors - Main semantical changes done: - solving unconstrained evars and reporting is not any longer mixed: one first tries to find unconstrained evars by any way possible; one eventually reports on the existence of unsolved evars using check_evars_are_solved - checking unsolved evars is now done by looking at the evar map, not by looking at the evars occurring in the terms to pretype; the only observed consequence so far is in Cases.v because of subterms (surprisingly) disappering after compilation of pattern-matching - the API changed, see dev/doc/changes.txt Still to do: - Find more uniform naming schemes: - for distinguishing when sigma is passed as a reference or as a value (are used: suffix _evars, prefix e_) - for distinguishing when evars are allowed to remain uninstantiated or not (are used: suffix _evars, again, suffix _tcc, infix _open_) - be more consistent on the use of names evd/sigma/evars or evdref/evars - By the way, shouldn't "understand" be better renamed into "infer" or "preinfer", or "pretype". Grammatically, "understanding a term" looks strange. - Investigate whether the inference flags in tacinterp.ml are really what we want (e.g. do we really want that heuristic remains activated when typeclasses are explicitly deactivated, idem in Tacinterp.interp_open_constr where flags are strange). git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@16499 85f007b7-540e-0410-9357-904b9bb8a0f7

2010-12-23Change of nomenclature: rawconstr -> glob_constrglondu
There was a discrepancy of the notions "raw" and "globalized" between constrs and tactics, and some confusion of the notions in e.g. genarg.mli (see all globwit_* there). This commit is a first step towards unification of terminology between constrs and tactics. Changes in module names will be done separately. In extraargs.ml4, the "ARGUMENT EXTEND raw" and related stuff, even affected by this change, has not been touched and highlights another confusion in "ARGUMENT EXTEND" in general that will be addressed later. The funind plugin doesn't respect the same naming conventions as the rest, so leave some "raw" there for now... they will be addressed later. This big commit has been generated with the following command (wrapped here, but should be on a *single* line): perl -pi -e 's/(\W(?:|pp|pr_l)|_)raw((?:constrs?|type|vars|_binder| _context|decl|_decompose|_compose|_make)(?:\W|_))/\1glob_\2/g;s/glo b__/glob_/g;s/prraw/prglob/g;s/(\W)R((?:Ref|Var|Evar|PatVar|App|Lam bda|Prod|LetIn|Cases|LetTuple|If|Rec|Sort|Hole|Cast|Dynamic)\W)/\1G \2/g' `git ls-files|grep -v dev/doc/changes.txt` git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@13743 85f007b7-540e-0410-9357-904b9bb8a0f7

dev/ocamlweb-doc has been erased. I hope no one still use the "new-parse" it generate. In dev/, make html will generate in dev/html/ "clickable version of mlis".

2009-11-11Improving abbreviations/notations + backtrack of semantic change in r12439herbelin
- 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
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

2009-03-28Rewrite 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
2009-01-17DISCLAIMERpuech
========== This big patch is commited here with a HUGE experimental tag on it. It is probably not a finished job. The aim of committing it now, as agreed with Hugo, is to get some feedback from potential users to identify more clearly the directions the implementation could take. So please feel free to mail me any remarks, bug reports or advices at <puech@cs.unibo.it>. Here are the changes induced by it : For the user ============ * Search tools have been reimplemented to be faster and more general. Affected are [SearchPattern], [SearchRewrite] and [Search] (not [SearchAbout] yet). Changes are: - All of them accept general constructions, and previous syntactical limitations are abolished. In particular, one can for example [SearchPattern (nat -> Prop)], which will find [isSucc], but also [le], [gt] etc. - Patterns are typed. This means that you cannot search mistyped expressions anymore. I'm not sure if it's a good or a bad thing though (especially regarding coercions)... * New tool to automatically infer (some) Record/Typeclasses instances. Usage : [Record/Class *Infer* X := ...] flags a record/class as subject to instance search. There is also an option to activate/deactivate the search [Set/Unset Autoinstance]. It works by finding combinations of definitions (actually all kinds of objects) which forms a record instance, possibly parameterized. It is activated at two moments: - A complete search is done when defining a new record, to find all possible instances that could have been formed with past definitions. Example: Require Import List. Record Infer Monoid A (op:A->A->A) e := { assoc : forall x y z, op x (op y z) = op (op x y) z; idl : forall x, x = op x e ; idr : forall x, x = op e x }. new instance Monoid_autoinstance_1 : (Monoid nat plus 0) [...] - At each new declaration (Definition, Axiom, Inductive), a search is made to find instances involving the new object. Example: Parameter app_nil_beg : forall A (l:list A), l = nil ++ l. new instance Build_Monoid_autoinstance_12 : (forall H : Type, Monoid (list H) app nil) := (fun H : Type => Build_Monoid (list H) app nil ass_app (app_nil_beg H) (app_nil_end H)) For the developper ================== * New yet-to-be-named datastructure in [lib/dnet.ml]. Should do efficient one-to-many or many-to-one non-linear first-order filtering, faster than traditional methods like discrimination nets (so yes, the name of the file should probably be changed). * Comes with its application to Coq's terms [pretyping/term_dnet.ml]. Terms are represented so that you can search for patterns under products as fast as you would do not under products, and facilities are provided to express other kind of searches (head of application, under equality, whatever you need that can be expressed as a pattern) * A global repository of all objects defined and imported is maintained [toplevel/libtypes.ml], with all search facilities described before. * A certain kind of proof search in [toplevel/autoinstance.ml]. For the moment it is specialized on finding instances, but it should be generalizable and reusable (more on this in a few months :-). The bad news ============ * Compile time should increase by 0 to 15% (depending on the size of the Requires done). This could be optimized greatly by not performing substitutions on modules which are not functors I think. There may also be some inefficiency sources left in my code though... * Vo's also gain a little bit of weight (20%). That's inevitable if I wanted to store the big datastructure of objects, but could also be optimized some more. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@11794 85f007b7-540e-0410-9357-904b9bb8a0f7
2008-12-29- Added support for subterm matching in SearchAbout.herbelin
- Backtrack on precise unfolding of "iff" in "tauto": it has effects on the naming of hypotheses (especially when doing "case H" with H of type "{x|P<->Q}" since not unfolding will eventually introduce a name "i" while unfolding will eventually introduce a name "a" (deep sigh). - Miscellaneous (error when a plugin is missing, doc hnf, standardization of names manipulating type constr_pattern, ...). git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@11725 85f007b7-540e-0410-9357-904b9bb8a0f7

2008-05-30Improvements on coqdoc by adding more information into .globmsozeau
files, about definitions and type of references. - Add missing location information on fixpoints/cofixpoint in topconstr and syntactic definitions in vernacentries for correct dumping. - Dump definition information in vernacentries: defs, constructors, projections etc... - Modify coqdoc/index.mll to use this information instead of trying to scan the file. - Use the type information in latex output, update coqdoc.sty accordingly. - Use the hyperref package to do crossrefs between definition and references to coq objects in latex. Next step is to test and debug it on bigger developments. On the side: - Fix Program Let which was adding a Global definition. - Correct implicits for well-founded Program Fixpoints. - Add new [Method] declaration kind. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@11024 85f007b7-540e-0410-9357-904b9bb8a0f7
2008-05-06Postpone the search for the recursive argument index from the user givenmsozeau

Use this opportunity to factorize the different internalization and interpretation functions of binders as well. This definitely fixes part 2 of bug #1846 and makes it possible to use fixpoint definitions with typeclass arguments in program too, with an example given in EquivDec. At the same time, one fix and one enhancement in Program: - fix a de Bruijn bug in subtac_cases - introduce locations of obligations and use them in case the obligation tactic raises a failure when tried on a particular obligation, as suggested by Sean Wilson. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@10889 85f007b7-540e-0410-9357-904b9bb8a0f7
2008-03-24Finish fix in command where we still lost information on what was a typemsozeau
and needed coercions. Change API of interp_constr_evars to get an optional evar_defs ref argument. Makes Algebra compile again (at least). git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@10715 85f007b7-540e-0410-9357-904b9bb8a0f7
2008-03-15Do a second pass on the treatment of user-given implicit arguments. Nowmsozeau
works in inductive type definitions and fixpoints. The semantics of an implicit inductive parameter is maybe a bit weird: it is implicit in the inductive definition of constructors and the contructor types but not in the inductive type itself (ie. to model the fact that one rarely wants A in vector A n to be implicit but in vnil yes). Example in test-suite/ Also, correct the handling of the implicit arguments across sections. Every definition which had no explicitely given implicit arguments was treated as if we asked to do global automatic implicit arguments on section closing. Hence some arguments were given implicit status for no apparent reason. Also correct and test the parsing rule which disambiguates between {wf ..} and {A ..}. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@10677 85f007b7-540e-0410-9357-904b9bb8a0f7

This patch introduces type classes and instance definitions a la Haskell. Technically, it uses the implicit arguments mechanism which was extended a bit. The patch also introduces a notation for explicitely marking implicit, maximally inserted parameters.
