2012-01-20Added new command "Set Parsing Explicit" for deactivating parsing (andherbelin
printing) of implicit arguments (a priori useful for teaching). git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@14928 85f007b7-540e-0410-9357-904b9bb8a0f7
2012-01-19Boolean Option Patterns Compatibilitypboutill
switch between "all arguments no parameters" and "explicit params and args" for constructor arguments in patterns. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@14919 85f007b7-540e-0410-9357-904b9bb8a0f7
2012-01-16Parameters in pattern first step.pboutill
In interp/constrintern.ml, '_' for constructor parameter are required if you use AppExpl ('@Constr') and added in order to be erased at the last time if you do not use '@'. It makes the use of notation in pattern more permissive. For example, -8<------ Inductive I (A: Type) : Type := C : A -> I A. Notation "x <: T" := (C T x) (at level 38). Definition uncast A (x : I A) := match x with | x <: _ => x end. -8<------ was forbidden. Backward compatibility is strictly preserved expect for syntactic definitions: While defining "Notation SOME = @Some", SOME had a special treatment and used to be an alias of Some in pattern. It is now uniformly an alias of @Some ('_' must be provided for parameters). In interp/constrextern.ml, except if all the parameters are implicit and all the arguments explicit (This covers all the cases of the test-suite), pattern are generated with AppExpl (id est '@') (so with '_' for parameters) in order to become compatible in any case with future behavior. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@14909 85f007b7-540e-0410-9357-904b9bb8a0f7
2011-11-07Allow "|_=>_" in "match" in patterns, no more forced enumeration of constructorsletouzey
For instance, consider this inductive type: Inductive Ind := A | B | C | D. For detecting "match" on this type, one was forced earlier to write code in Ltac using "match goal" and/or "context [...]" and long patterns such as: match _ with A => _ | B => _ | C => _ | D => _ end After this patch, this pattern can be shortened in many alternative ways: match _ with A => _ | _ => _ end match _ with B => _ | _ => _ end match _ in Ind with _ => _ end Indeed, if we want to detect a "match" of a given type, we can either leave at least one branch where a constructor is explicit, or use a "in" annotation. Now, we can also detect any "match" regardless of its type: match _ with _ => _ end Note : this will even detect "match" over empty inductive types. Compatibility should be preserved, since "match _ with end" will continue to correspond only to empty inductive types. Internally, the constr_pattern PCase has changed quite a lot, a few elements are now grouped into a case_info_pattern record, while branches are now lists of given sub-patterns. NB: writing "match" with missing last branches in a constr pattern was actually tolerated by Pattern.pattern_of_glob_constr earlier, since the number of constructor per inductive is unknown there. And this was triggering an uncaught exception in a array_fold_left_2 in Matching later. Oups. At least this patch fixes this issue... Btw: the code in Pattern.pattern_of_glob_constr was quadratic in the number of branch in a match pattern. I doubt this was really a problem, but having now linear code instead cannot harm ;-) git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@14644 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

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

2009-04-08Some dead code removal + cleanupsletouzey
This commit concerns about the first half of the useless code mentionned by Oug for coqtop (without plugins). For the moment, Oug is used in a mode where any elements mentionned in a .mli is considered to be precious. This already allows to detect and remove about 600 lines, and more is still to come. Among the interesting points, the type Entries.specification_entry and its constructors SPExxx were never used. Large parts of cases.ml (and hence subtac_cases.ml) were also useless. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@12069 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

2008-10-23Open notation for declaring record instances.msozeau
It solves feature request 1852, makes me and Arnaud happy and will permit to factor some more code in typeclasses. - Records are introduced using the syntax "{| x := t; y := foo |}" and "with" clauses are currently parsed but not yet supported in the elaboration. You are invited to suggest other syntaxes :) - Missing fields are turned into holes, extra fields cause an error message. The current implementation finds the type of the record at pretyping time, from the typing constraint alone (and just expects an inductive with one constructor). It is then impossible to use scope information to parse the bodies: that may be wrong. The other solution I see is using the fields to detect the type earlier, before internalisation of the bodies, but then we get in name clash hell. - In funind/contrib/interface I mostly put [assert false] everywhere to avoid warnings. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@11496 85f007b7-540e-0410-9357-904b9bb8a0f7

2008-05-06Postpone the search for the recursive argument index from the user givenmsozeau
name after internalisation, to get the correct behavior with typeclass binders. This simplifies the pretty printing and translation of the recursive argument name in various places too. 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

This factors out most code and we lose no functionality (win ! win !). Add LetPat.v test suite. - Slight improvement of inference of return clauses for dependent pattern matching. If matching a variable of non-dependent type under a tycon that mentions it while giving no return clause, the dependency will be automatically infered. Examples at the end of DepPat. Should get rid of most explicit returns under tycons. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@10727 85f007b7-540e-0410-9357-904b9bb8a0f7
