2010-01-07Include can accept both Module and Module Typeletouzey
Syntax Include Type is still active, but deprecated, and triggers a warning. The syntax M <+ M' <+ M'', which performs internally an Include, also benefits from this: M, M', M'' can be independantly modules or module type. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@12640 85f007b7-540e-0410-9357-904b9bb8a0f7
2010-01-04Specific syntax for Instances in Module Type: Declare Instanceletouzey
NB: the grammar entry is placed in vernac:command on purpose even if it should have gone into vernac:gallina_ext. Camlp4 isn't factorising rules starting by "Declare" in a correct way otherwise... git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@12623 85f007b7-540e-0410-9357-904b9bb8a0f7

2009-12-14Improved strategy for rewriting lemma possibly depending because of evars.herbelin
Explained in CHANGES how to cope with the change of semantics of abbreviations wrt implicit arguments positions propagation. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@12586 85f007b7-540e-0410-9357-904b9bb8a0f7
2009-12-13Addition of mergesort + cleaning of the Sorting libraryherbelin
- New (modular) mergesort purely using structural recursion - Move of the (complex) notion of permutation up to setoid equality formerly defined in Permutation.v to file PermutSetoid.v - Re-use of the file Permutation.v for making the canonical notion of permutation that was in List.v more visible - New file Sorted.v that contains two definitions of sorted: "Sorted" is a renaming of "sort" that was defined in file Sorting.v and "StronglySorted" is the intuitive notion of sorted (there is also LocallySorted which is a variant of Sorted) - File Sorting.v is replaced by a call to the main Require of the directory - The merge function whose specification rely on counting elements is moved to Heap.v and both are stamped deprecated (the sort defined in Heap.v has complexity n^2 in worst case) - Added some new naming conventions - Removed uselessly-maximal implicit arguments of Forall2 predicate git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@12585 85f007b7-540e-0410-9357-904b9bb8a0f7
2009-12-13Made the side-conditions of lemmas always come last when chaining "apply in"herbelin
in presence of destruction of conjunctive types. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@12584 85f007b7-540e-0410-9357-904b9bb8a0f7
2009-12-12Updated compatibility for rewriting equality proofs that are dependentherbelin
- made the new "subst'" the default by renaming it "subst"; - renamed old "subst" into "simple subst"; - add option for non-rewriting of dependent proofs in general_rewrite and co - kept use of dependent proofs in the "subst" call of "functional induction", in spite it introduced incompatibilities (in Compcert). git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@12578 85f007b7-540e-0410-9357-904b9bb8a0f7
2009-12-03Still continuing r12485-12486, r12549, r12556 (cleaning around name generation)herbelin
Removed one more bug in simplification of visibly_occur_id in r12549 + improved CHANGES message git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@12561 85f007b7-540e-0410-9357-904b9bb8a0f7
2009-12-02Continuing r12485-12486 and r12549 (cleaning around name generation)herbelin
- fixed misunderstanding of the role of nenv while simplifying code of occur_id in namegen.ml, - documented the possible incompatibilites in CHANGES - fixed output/Naming.v test, and fixed the count of misc. tests in test-suite/check. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@12556 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

abbreviations of applied references. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@12506 85f007b7-540e-0410-9357-904b9bb8a0f7
2009-11-11Added support for multiple where-clauses in Inductive and co (see wish #2163).herbelin
git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@12500 85f007b7-540e-0410-9357-904b9bb8a0f7
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
2009-11-04Fixed record syntax "{|x=...; y=...|}" so that it works with qualified names.gmelquio
Fixed pretty printing of record syntax. Allowed record syntax inside patterns. (Patch by Cedric Auger.) git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@12468 85f007b7-540e-0410-9357-904b9bb8a0f7
2009-10-28Made that notations to names behave like the names they refer to wrtherbelin
implicit arguments and scope (use Implicit Arguments or Arguments Scope commands instead if not the desired behaviour). git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@12439 85f007b7-540e-0410-9357-904b9bb8a0f7
2009-10-27Added option --external to coqdoc to bind an url to an external library.herbelin
git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@12426 85f007b7-540e-0410-9357-904b9bb8a0f7
2009-10-26New cleaning phase of the Local/Global option managementherbelin
- Clarification and documentation of the different styles of Local/Global modifiers in vernacexpr.ml - Addition of Global in sections for Open/Close Scope. - Addition of Local for Ltac when not in sections. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@12418 85f007b7-540e-0410-9357-904b9bb8a0f7
2009-10-08Fixed clash names in Relations (see bug report #2152) and make namesherbelin

2009-10-08Implicit argument of Logic.eq become maximally insertedletouzey
This allow in particular to write eq instead of (@eq _) in signatures of morphisms. I dont really see how this could break existing code, no change in the stdlib was mandatory. We'll check the contribs tomorrow... git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@12379 85f007b7-540e-0410-9357-904b9bb8a0f7
2009-10-03Added option "Unset Dependent Propositions Elimination" to protectherbelin
against the incompatibilities introduced by making "destruct" working on dependent propositions (incompatibilities come from uses of destruct in Ltac definitions such as "destruct_conjs"). git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@12367 85f007b7-540e-0410-9357-904b9bb8a0f7
2009-09-20Add "case as/in/using" and temporary "destruct" with n args.herbelin
git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@12347 85f007b7-540e-0410-9357-904b9bb8a0f7
2009-09-13- Inductive types in the "using" option of auto/eauto/firstorder areherbelin
interpreted as using the collection of their constructors as hints. - Add support for both "using" and "with" in "firstorder". Made the syntax of "using" compatible with the one of "auto" by separating lemmas by commas. Did not fully merge the syntax: auto accepts constr while firstorder accepts names (but are constr really useful?). - Added "Reserved Infix" as a specific shortcut of the corresponding "Reserved Notation". git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@12325 85f007b7-540e-0410-9357-904b9bb8a0f7

2009-09-11Added the following lemmas to homogenize Reals a bit:gmelquio
- Rmult_eq_compat_r, Rmult_eq_reg_r, Rplus_le_reg_r, Rmult_lt_reg_r, Rmult_le_reg_r (mirrored variants of the existing _l lemmas); - minus_IZR, opp_IZR (Ropp_Ropp_IZR), abs_IZR (mirrored Rabs_Zabs); - Rle_abs (RRle_abs); - Zpower_pos_powerRZ (signed variant of Zpower_nat_powerRZ). git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@12321 85f007b7-540e-0410-9357-904b9bb8a0f7

2009-08-24New tactic to rewrite decidability lemmas when one knows which sideherbelin
is true. E.g. "decide (eq_nat_dec n 0) with H" on H: n=0 |- (if eq_nat_dec n 0 then 1 else 2) = 1 returns H: n=0 |- 1 = 1 . git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@12291 85f007b7-540e-0410-9357-904b9bb8a0f7
2009-08-06Move out JMeq of subst for compatibility (it affects e.g. theherbelin
compilation of Grenoble/ATBR). Add subst' for subst extended with JMeq (maybe an option would be better??). git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@12264 85f007b7-540e-0410-9357-904b9bb8a0f7
2009-08-03Added "etransitivity".herbelin
Added support for "injection" and "discriminate" on JMeq. Seized the opportunity to update coqlib.ml and to rely more on it for finding the equality lemmas. Fixed typos in coqcompat.ml. Propagated symmetry convert_concl fix to transitivity (see 11521). git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@12259 85f007b7-540e-0410-9357-904b9bb8a0f7
2009-08-02Improved parameterization of Coq:herbelin
- add coqtop option "-compat X.Y" so as to provide compatibility with previous versions of Coq (of course, this requires to take care of providing flags for controlling changes of behaviors!), - add support for option names made of an arbitrary length of words (instead of one, two or three words only), - add options for recovering 8.2 behavior for discriminate, tauto, evar unification ("Set Tactic Evars Pattern Unification", "Set Discriminate Introduction", "Set Intuition Iff Unfolding"). Update of .gitignore git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@12258 85f007b7-540e-0410-9357-904b9bb8a0f7
2009-07-22Better comparison functions in OrderedTypeExletouzey
The compare functions are still functions-by-tactics, but now their computational parts are completely pure (no use of lt_eq_lt_dec in nat_compare anymore), while their proofs parts are simply calls to (opaque) lemmas. This seem to improve the efficiency of sets/maps, as mentionned by T. Braibant, D. Pous and S. Lescuyer. The earlier version of nat_compare is now called nat_compare_alt, there is a proof of equivalence named nat_compare_equiv. By the way, various improvements of proofs, in particular in Pnat. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@12247 85f007b7-540e-0410-9357-904b9bb8a0f7

2009-05-10- Addition of "Hint Resolve ->" and "Hint Resolve <-" continued: itherbelin
revealed a too strict test for detection of inferable metas in Clenv. Restored tolerance for unbound names in interactive tactic use. - Moral removals of some captures of Not_found in Environ.evaluable_* since kernel is assumed to deal with existing names. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@12122 85f007b7-540e-0410-9357-904b9bb8a0f7
2009-04-27- Cleaning (unification of ML names, removal of obsolete code,herbelin
reorganization of code) and documentation (in pcoq.mli) of the code for parsing extensions (TACTIC/VERNAC/ARGUMENT EXTEND, Tactic Notation, Notation); merged the two copies of interp_entry_name to avoid they diverge. - Added support in Tactic Notation for ne_..._list_sep in general and for (ne_)ident_list(_sep) in particular. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@12108 85f007b7-540e-0410-9357-904b9bb8a0f7
