* | [api] Move universe syntax to `Glob_term`Gravatar Emilio Jesus Gallego Arias2018-05-08
|/ | | | | | | | | | | | | We move syntax for universes from `Misctypes` to `Glob_term`. There is basically no reason that this type is there instead of the proper file, as witnessed by the diff. Unfortunately the change is not compatible due to moving a type to a higher level in the hierarchy, but we expect few problems. This change plus the related PR (#6515) moving universe declaration to their proper place make `Misctypes` into basically an empty file save for introduction patterns.
* Deprecate mixing univ minimization and evm normalization functions.Gravatar Gaëtan Gilbert2018-04-17

* Fixing the 3 cases of a "Stream.Error" ended with two periods.Gravatar Hugo Herbelin2018-04-12
| | | | | The "Stream.Error" printer does add a period, so, the messages themselves should not.
* [located] Push inner locations in `reference` to a CAst.t node.Gravatar Emilio Jesus Gallego Arias2018-03-09
| | | | | | | | | | | | | | The `reference` type contains some ad-hoc locations in its constructors, but there is no reason not to handle them with the standard attribute container provided by `CAst.t`. An orthogonal topic to this commit is whether the `reference` type should contain a location or not at all. It seems that many places would become a bit clearer by splitting `reference` into non-located `reference` and `lreference`, however some other places become messier so we maintain the current status-quo for now.

* | [econstr] Continue consolidation of EConstr API under `interp`.Gravatar Emilio Jesus Gallego Arias2018-02-28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This commit was motivated by true spurious conversions arising in my `to_constr` debug branch. The changes here need careful review as the tradeoffs are subtle and still a lot of clean up remains to be done in `vernac/*`. We have opted for penalize [minimally] the few users coming from true `Constr`-land, but I am sure we can tweak code in a much better way. In particular, it is not clear if internalization should take an `evar_map` even in the cases where it is not triggered, see the changes under `plugins` for a good example. Also, the new return type of `Pretyping.understand` should undergo careful review. We don't touch `Impargs` as it is not clear how to proceed, however, the current type of `compute_implicits_gen` looks very suspicious as it is called often with free evars. Some TODOs are: - impargs was calling whd_all, the Econstr equivalent can be either + Reductionops.whd_all [which does refolding and no sharing] + Reductionops.clos_whd_flags with all as a flag.

* [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.
* Use specialized function for inductive subtyping inference.Gravatar Gaëtan Gilbert2018-02-11
| | | | | This ensures by construction that we never infer constraints outside the variance model.

* Simplification: cumulativity information is variance information.Gravatar Gaëtan Gilbert2018-02-10
| | | | | | | | | | | | | | | | | | | | | | | | | Since cumulativity of an inductive type is the universe constraints which make a term convertible with its universe-renamed copy, the only constraints we can get are between a universe and its copy. As such we do not need to be able to represent arbitrary constraints between universes and copied universes in a double-sized ucontext, instead we can just keep around an array describing whether a bound universe is covariant, invariant or irrelevant (CIC has no contravariant conversion rule). Printing is fairly obtuse and should be improved: when we print the CumulativityInfo we add marks to the universes of the instance: = for invariant, + for covariant and * for irrelevant. ie Record Foo@{i j k} := { foo : Type@{i} -> Type@{j} }. Print Foo. gives Cumulative Record Foo : Type@{max(i+1, j+1)} := Build_Foo { foo : Type@{i} -> Type@{j} } (* =i +j *k |= *)
* [api] Also deprecate constructors of Decl_kinds.Gravatar Emilio Jesus Gallego Arias2017-12-23
| | | | | | | | Unfortunately OCaml doesn't deprecate the constructors of a type when the type alias is deprecated. In this case it means that we don't get rid of the kernel dependency unless we deprecate the constructors too.
* [vernac] Split `command.ml` into separate files.Gravatar Emilio Jesus Gallego Arias2017-12-17
Over the time, `Command` grew organically and it has become now one of the most complex files in the codebase; however, its functionality is well separated into 4 key components that have little to do with each other. We thus split the file, and also document the interfaces. Some parts of `Command` export tricky internals to use by other plugins, and it is common that plugin writers tend to get confused, so we are more explicit about these parts now. This patch depends on #6413.
