2007-12-05Factorisation des opérations sur le type option de Util dans un module aspiwack
lib/option.ml(i) . J'en profite pour rajouter des primitives de lifting des fonctions (à un ou deux arguments tous ou partie de type option). Il reste quelques opérations dans Util à propos desquelles je ne suis pas trop sûr, ou simplement que j'ai oublié, mais qui attendront demain car il est tard (comme some_in qui devrait devenir Option.make je suppose) . Elles s'expriment souvent facilement en fonction des autres, par exemple "option_compare x y" est égal à "Option.lift2 compare x y" . Le option_cons devrait faire son chemin dans le module parce qu'il est assez primitif et qu'il n'y a pas de fonction "cons" dans OCaml. J'en ai profité aussi pour remplacer les trop nombreux "failwith" par des erreurs locales au module, donc plus robustes. J'ai trouvé aussi une fonction qui était définie deux fois, et une définie dans un module particulier. Mon seul bémol (mais facile à traiter) c'est la proximité entre le nom de module Option et l'ancien Options. J'ai pas de meilleure idée de nom à l'heure qu'il est, ni pour l'un, ni pour l'autre. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@10346 85f007b7-540e-0410-9357-904b9bb8a0f7

2007-10-17Major reorganisation of the extraction "backend".letouzey
Initial Idea: getting rid of nasty renaming issues in modules, in particular bugs #820 (part d) #1340 #1526 #1654 Final effect: lots of changes, simplifications, cleanups, unrelated fixes and ehancements, and also probably some regressions (time will tell). A few details: * no more experimental "Toplevel" language. * no more functors Make in Ocaml/Haskell/Scheme. The spirit of these functors and Mlpp_params was already not followed much, and this framework was more a nuisance that anything else. * instead, some records language_descr regrouping the specific features of the different output languages. * Common now comes before Ocaml/Haskell/Scheme, these ones are now independant from each others. print_structure_to_file is now in Extract_env. * A nice detail: no more duplications of warnings concerning axioms. * In modular extraction, the clashes due to the opened modules are now computed once and for all thanks to record_contents_fstlev, instead of re-asking Coq each time about these opened modules and using Extraction.constant_kind * some utilities about modules_path added and/or moved from Modutil to Table. * using a .v file as a module, e.g. in a functor application should now works in modular extraction. Now concerning renaming issues themselves: * printing is done twice, the first time toward /dev/null, in order to encounter the naming issues unsolvable by a simple qualification. On the second run, we create artificial modules Coq__123 for allowing qualification of these hidden objects. * names are now fully separated into their syntaxic categories: terms/types/constructors/modules * Only one last unsupported situation (but at least detected and signaled by an error): an object M.t from an external file-module M.v can't be printed when a local module M is in the way. This situation is really unlikely (in Coq you must use _long_ file-module name, e.g. Init.Datatypes.nat). It could be solved by inserting "module Coq_123 = M" at the beginning of the file, but then the signature of Coq_123 (that is, the one of M) should be written explicitely in the .mli, which is _really_ not nice. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@10232 85f007b7-540e-0410-9357-904b9bb8a0f7

2007-10-08Better use of tables for storing results of extract_ind (bug #1709)letouzey
It is critical to avoid duplicated calls to extract_ind (see e.g. example in #1709). But the same kernel_name can lead to different inductive bodies, due to module substitutions. So we used to factorize only "visible" kn, that were not subject to change under substitution. As shown by P. Cregut in #1709, this is not enough. New approach is now to store also Coq inductive data (mib). If the recorded mib matches the current one, we trust the recorded result, otherwise we start a fresh computation of extract_ind. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@10194 85f007b7-540e-0410-9357-904b9bb8a0f7
2007-10-06Allowing infix constructors/types in a Extract Inductiveletouzey
If a constructor has two arguments and the corresponding string given in a Extract Inductive is of the form "(foo)", then foo is used as an infix constructor. Idem for a inductive type name. Examples: Extract Inductive list => list [ "[]" "(::)" ]. Extract Inductive prod => "(*)" [ "(,)" ]. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@10188 85f007b7-540e-0410-9357-904b9bb8a0f7
2007-10-06Extraction: factorisation of identical branches in a matchletouzey
If a match has two or more identical branches (that moreover do not depend on their pattern variables), we merge them in a last branch whose pattern is _ If _all_ branches are identical, we just remove the match git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@10186 85f007b7-540e-0410-9357-904b9bb8a0f7
