* 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.

* More monomorphic List.mem + List.assoc + ...Gravatar letouzey2013-10-24
| | | | | | | | | | | To reduce the amount of syntactic noise, we now provide a few inner modules Int.List, Id.List, String.List, Sorts.List which contain some monomorphic (or semi-monomorphic) functions such as mem, assoc, ... NB: for Int.List.mem and co we reuse List.memq and so on. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@16936 85f007b7-540e-0410-9357-904b9bb8a0f7
