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
2008-12-16Move FunctionalExtensionality to Logic/ (someone please check that themsozeau
doc is ok). Rework the .v files in Program accordingly, adding some documentation and proper headers. Integrate the development of an elimination principle for measured functions in Program/Wf by Eelis van der Weegen. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@11686 85f007b7-540e-0410-9357-904b9bb8a0f7
2008-05-15Various fixes:msozeau
- Fix a typo in lowercase_utf8 - Fix generation of signatures in subtac_cases not working for dependent inductive types with dependent indices. - Fix coercion of inductive types generating ill-typed terms. - Fix test script using new syntax for Instances. - Move simpl_existTs to Program.Equality and use it in simpl_depind. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@10932 85f007b7-540e-0410-9357-904b9bb8a0f7
2008-05-12- Add -unicode flag to coqtop (sets Flags.unicode_syntax). Used tomsozeau
change the default pretty-printing to use Π, λ instead of forall and fun (and allow "," as well as "=>" for "fun" to be more consistent with the standard forall and exists syntax). Parsing allows theses new forms too, even if not in -unicode, and does not make Π or λ keywords. As usual, criticism and suggestions are welcome :) Not sure what to do about "->"/"→" ? - [setoid_replace by] now uses tactic3() to get the right parsing level for tactics. - Type class [Instance] names are now mandatory. - Document [rewrite at/by] and fix parsing of occs to support their combination. - Backtrack on [Enriching] modifier, now used exclusively in the implementation of implicit arguments. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@10921 85f007b7-540e-0410-9357-904b9bb8a0f7
2008-05-11- Cleanup parsing of binders, reducing to a single production for allmsozeau
binders. - Change syntax of type class instances to better match the usual syntax of lemmas/definitions with name first, then arguments ":" instance. Update theories/Classes accordingly. - Correct globalization of tactic references when doing Ltac :=/::=, update documentation. - Remove the not so useful "(x &)" and "{{x}}" syntaxes from Program.Utils, and subset_scope as well. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@10919 85f007b7-540e-0410-9357-904b9bb8a0f7
2008-04-05Minor fixes: msozeau
- Allow unicode superscripts characters. - Put Program notations in scopes. - Correct priority semantics in typeclasses eauto. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@10759 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
2008-02-26Proper implicit arguments handling for assumptionsmsozeau
(Axiom/Variable...). New tactic clapply to apply unapplied class methods in tactic mode, simple solution to the fact that apply does not work up-to classes yet. Add Functions.v for class definitions related to functional morphisms. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@10589 85f007b7-540e-0410-9357-904b9bb8a0f7
