* Swapping Context and Constr: defining declarations on constr in Constr.Gravatar Hugo Herbelin2018-06-27
| | | | | | | | | This shall eventually allow to use contexts of declarations in the definition of the "Case" constructor. Basically, this means that Constr now includes Context and that the "t" types of Context which were specialized on constr are not defined in Constr (unfortunately using a heavy boilerplate).
* Remove reference name type.Gravatar Maxime Dénès2018-06-18
| | | | | | | | reference was defined as Ident or Qualid, but the qualid type already permits empty paths. So we had effectively two representations for unqualified names, that were not seen as equal by eq_reference. We remove the reference type and replace its uses by qualid.

* [api] Move `Constrexpr` to the `interp` module.Gravatar Emilio Jesus Gallego Arias2018-05-31
| | | | | | | | | | | | | | | | | | Continuing the interface cleanup we place `Constrexpr` in the internalization module, which is the one that eliminates it. This slims down `pretyping` considerably, including removing the `Univdecls` module which existed only due to bad dependency ordering in the first place. Thanks to @ Skyskimmer we also remove a duplicate `univ_decl` definition among `Misctypes` and `UState`. This is mostly a proof of concept yet as it depends on quite a few patches of the tree. For sure some tweaks will be necessary, but it should be good for review now. IMO the tree is now in a state where we can could easy eliminate more than 10 modules without any impact, IMHO this is a net saving API-wise and would help people to understand the structure of the code better.
* [api] Move `Vernacexpr` to parsing.Gravatar Emilio Jesus Gallego Arias2018-05-23
| | | | | | There were a few spurious dependencies on the `Vernac` AST in the pretyper, we remove them and move `Vernacexpr` and `Extend` to parsing, where they do belong more.
* [api] Rename `global_reference` to `GlobRef.t` to follow kernel style.Gravatar Emilio Jesus Gallego Arias2018-05-04
| | | | | | | | | | | | | In #6092, `global_reference` was moved to `kernel`. It makes sense to go further and use the current kernel style for names. This has a good effect on the dependency graph, as some core modules don't depend on library anymore. A question about providing equality for the GloRef module remains, as there are two different notions of equality for constants. In that sense, `KerPair` seems suspicious and at some point it should be looked at.

* [ast] Improve precision of Ast location recognition in serialization.Gravatar Emilio Jesus Gallego Arias2018-02-22
| | | | | | | | | We follow the suggestions in #402 and turn uses of `Loc.located` in `vernac` into `CAst.t`. The impact should be low as this change mostly affects top-level vernaculars. With this change, we are even closer to automatically map a text document to its AST in a programmatic way.

* [location] Make location optional in Loc.locatedGravatar Emilio Jesus Gallego Arias2017-04-25
| | | | | | | | | | | | This completes the Loc.ghost removal, the idea is to gear the API towards optional, but uniform, location handling. We don't print <unknown> anymore in the case there is no location. This is what the test suite expects. The old printing logic for located items was a bit inconsistent as it sometimes printed <unknown> and other times it printed nothing as the caller checked for `is_ghost` upstream.
* Renaming local_binder into local_binder_expr.Gravatar Hugo Herbelin2017-03-24

* CLEANUP: Context.{Rel,Named}.Declaration.tGravatar Matej Kosik2016-02-09
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Originally, rel-context was represented as: Context.rel_context = Names.Name.t * Constr.t option * Constr.t Now it is represented as: Context.Rel.t = LocalAssum of Names.Name.t * Constr.t | LocalDef of Names.Name.t * Constr.t * Constr.t Originally, named-context was represented as: Context.named_context = Names.Id.t * Constr.t option * Constr.t Now it is represented as: Context.Named.t = LocalAssum of Names.Id.t * Constr.t | LocalDef of Names.Id.t * Constr.t * Constr.t Motivation: (1) In "tactics/hipattern.ml4" file we define "test_strict_disjunction" function which looked like this: let test_strict_disjunction n lc = Array.for_all_i (fun i c -> match (prod_assum (snd (decompose_prod_n_assum n c))) with | [_,None,c] -> isRel c && Int.equal (destRel c) (n - i) | _ -> false) 0 lc Suppose that you do not know about rel-context and named-context. (that is the case of people who just started to read the source code) Merlin would tell you that the type of the value you are destructing by "match" is: 'a * 'b option * Constr.t (* worst-case scenario *) or Named.Name.t * Constr.t option * Constr.t (* best-case scenario (?) *) To me, this is akin to wearing an opaque veil. It is hard to figure out the meaning of the values you are looking at. In particular, it is hard to discover the connection between the value we are destructing above and the datatypes and functions defined in the "kernel/context.ml" file. In this case, the connection is there, but it is not visible (between the function above and the "Context" module). ------------------------------------------------------------------------ Now consider, what happens when the reader see the same function presented in the following form: let test_strict_disjunction n lc = Array.for_all_i (fun i c -> match (prod_assum (snd (decompose_prod_n_assum n c))) with | [LocalAssum (_,c)] -> isRel c && Int.equal (destRel c) (n - i) | _ -> false) 0 lc If the reader haven't seen "LocalAssum" before, (s)he can use Merlin to jump to the corresponding definition and learn more. In this case, the connection is there, and it is directly visible (between the function above and the "Context" module). (2) Also, if we already have the concepts such as: - local declaration - local assumption - local definition and we describe these notions meticulously in the Reference Manual, then it is a real pity not to reinforce the connection of the actual code with the abstract description we published.

* Change of nomenclature: rawconstr -> glob_constrGravatar glondu2010-12-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* Rewrite of Program Fixpoint to overcome the previous limitations: Gravatar msozeau2009-03-28
| | | | | | | | | | | | | | | - 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
* Open notation for declaring record instances.Gravatar msozeau2008-10-23
| | | | | | | | | | | | | | | | | | | | 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

Subject to discussion! A few examples added in a test-suite file. - Also add missing syntax for implicit/explicit combinations for _binders_: "{( )}" means implicit for the generalized (outer) vars, explicit for the (inner) variable itself. Subject to discussion as well :) - Factor much typeclass instance declaration code. We now just have to force generalization of the term after the : in instance declarations.

For singleton classes the implementation of the class becomes a regular definition (into Type or Prop). The single method becomes a 'trivial' projection that allows to launch typeclass resolution. Each instance is just a definition as usual. Examples in theories/Classes/RelationClasses. This permits to define [Class reflexive A (R : relation A) := refl : forall x, R x x.]. The definition of [reflexive] that is generated is the same as the original one. We just need a way to declare arbitrary lemmas as instances of a particular class to retrofit existing reflexivity lemmas as typeclass instances of the [reflexive] class. Also debug rewriting under binders in setoid_rewrite to allow rewriting with lemmas which capture the bound variables when applied (works only with setoid_rewrite, as rewrite first matches the lemma with the entire, closed term). One can rewrite with [H : forall x, R (f x) (g x)] in the goal [exists x, P (f x)]. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@10697 85f007b7-540e-0410-9357-904b9bb8a0f7
