* Correct some spelling errorsmasterGravatar Benjamin Barenblat2018-07-22
| | | | | | | | | | Lintian found some spelling errors in the Debian packaging for coq. Fix them most places they appear in the current source. (Don't change documentation anchor names, as that would invalidate external deeplinks.) This also fixes a bug in coqdoc: prior to this commit, coqdoc would highlight `instanciate` but not `instantiate`.
* Change QuestionMark for better record field missing error message.Gravatar Siddharth Bhat2018-07-17
| | | | | | | | | | While we were adding a new field into `QuestionMark`, we decided to go ahead and refactor the constructor to hold an actual record. This record now holds the name, obligations, and whether the evar represents a missing record field. This is used to provide better error messages on missing record fields.
* 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).

* | Fix handling of universe context for expanded program obligations.Gravatar Matthieu Sozeau2018-06-22

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| * Fix an anomaly when calling Obligation 0 or Obligation -1.Gravatar Théo Zimmermann2018-05-21
| | | | | | | | | | | | | | | | | | I didn't change the parser which expects an integer instead of a positive number because changing it would also mean having worse error messages because of our current LL parser. The error message would have been: Syntax error: 'Tactic' ':=' expected after 'Obligation' (in [vernac:command]).

* [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.
* Evar maps contain econstrs.Gravatar Gaëtan Gilbert2018-04-13
| | | | | | We bootstrap the circular evar_map <-> econstr dependency by moving the internal EConstr.API module to Evd.MiniEConstr. Then we make the Evd functions use econstr.
* Allow using cumulativity without forcing strict constraints.Gravatar Gaëtan Gilbert2018-03-09
| | | | | | | | | | | | | | | | | | | | | | | | Previously [fun x : Ind@{i} => x : Ind@{j}] with Ind some cumulative inductive would try to generate a constraint [i = j] and use cumulativity only if this resulted in an inconsistency. This is confusingly different from the behaviour with [Type] and means cumulativity can only be used to lift between universes related by strict inequalities. (This isn't a kernel restriction so there might be some workaround to send the kernel the right constraints, but not in a nice way.) See modified test for more details of what is now possible. Technical notes: When universe constraints were inferred by comparing the shape of terms without reduction, cumulativity was not used and so too-strict equality constraints were generated. Then in order to use cumulativity we had to make this comparison fail to fall back to full conversion. When unifiying 2 instances of a cumulative inductive type, if there are any Irrelevant universes we try to unify them if they are flexible.

* [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.

* | Fix #6323: stronger restrict universe context vs abstract.Gravatar Gaëtan Gilbert2017-12-06

* Cleanup API for registering universe binders.Gravatar Matthieu Sozeau2017-12-01
| | | | | | | | | | | | | | | | | | | | | | | | | | | | - Regularly declared for for polymorphic constants - Declared globally for monomorphic constants. E.g mono@{i} := Type@{i} is printed as mono@{mono.i} := Type@{mono.i}. There can be a name clash if there's a module and a constant of the same name. It is detected and is an error if the constant is first but is not detected and the name for the constant not registered (??) if the constant comes second. Accept VarRef when registering universe binders Fix two problems found by Gaëtan where binders were not registered properly Simplify API substantially by not passing around a substructure of an already carrier-around structure in interpretation/declaration code of constants and proofs Fix an issue of the stronger restrict universe context + no evd leak This is uncovered by not having an evd leak in interp_definition, and the stronger restrict_universe_context. This patch could be backported to 8.7, it could also be triggered by the previous restrict_context I think.

Inductive P {n : nat} : nat -> Prop := c m : *m where "* m" := (P m). We seize this opportunity to make main calls to Metasyntax to depend on an arbitrary env rather than on Global.env. Incidentally, this fixes a little coqdoc bug in classifying the inductive type referred to in the "where" clause.

* Allow declaring universe constraints at definition level.Gravatar Matthieu Sozeau2017-09-19
| | | | | | | | | | | | | | Introduce a "+" modifier for universe and constraint declarations to indicate that these can be extended in the final definition/proof. By default [Definition f] is equivalent to [Definition f@{+|+}], i.e universes can be introduced and constraints as well. For [f@{}] or [f@{i j}], the constraints can be extended, no universe introduced, to maintain compatibility with existing developments. Use [f@{i j | }] to indicate that no constraint (nor universe) can be introduced. These kind of definitions could benefit from asynchronous processing. Declarations of universe binders and constraints also works for monomorphic definitions.
