* | Cleaning up the implementation of module subtyping in the kernel.Gravatar Pierre-Marie Pédrot2017-07-11
| | | | | | | | | | | | | | | | We export a function in UGraph to check that a polymorphic instance is a subtype of another, instead of rolling up our own in module code. We also add a few tests for module subtyping in presence of polymorphic constants.
* | Safe API for accessing universe constraints of global references.Gravatar Pierre-Marie Pédrot2017-07-11
| | | | | | | | | | | | Instead of returning either an instance or the set of constraints, we rather return the corresponding abstracted context. We also push back all uses of abstraction-breaking calls from these functions out of the kernel.
* | Less footguns in universe handling: remove subst_instance_context.Gravatar Pierre-Marie Pédrot2017-07-11
| | | | | | | | | | This function was lurking around, waiting to bite anybody willing to use it. We use instead a better API, correct and much less error-prone.
* | Asserting that monomorphic section variables have no abstracted context.Gravatar Pierre-Marie Pédrot2017-07-11
| |
* | Getting rid of simple calls to AUContext.instance.Gravatar Pierre-Marie Pédrot2017-07-11
| | | | | | | | | | | | This function breaks the abstraction barrier of abstract universe contexts, as it provides a way to observe the bound names of such a context. We remove all the uses that can be easily get rid of with the current API.
* | Removing a redundant universe instance information in native compute.Gravatar Pierre-Marie Pédrot2017-07-10
| | | | | | | | | | | | Global declarations used to carry universe instances with them, but it turns out this information is not used anywhere. Instead, instances were already properly encoded as the first argument of polymorphic definitions.

| * | Removing dead code in Subtyping.Gravatar Pierre-Marie Pédrot2017-07-04
| | | | | | | | | | | | | | | | | | | | | This code was a sketch of what to do when we properly implement module-level handling of instanciation of definitions by inductive types. It was completely dead code, called after an error, and somewhat incorrect. Instead of letting it bitrot, we remove it.
| * | Removing a few suspicious functions from the kernel.Gravatar Pierre-Marie Pédrot2017-07-03
| | | | | | | | | | | | | | | | | | These functions were messing with the deferred universe constraints in an error-prone way, and were only used for printing as of today. We inline the one used by the printer instead.
| * | Do not add original constraints to the environment in 'with Definition' check.Gravatar Pierre-Marie Pédrot2017-07-03
|/ / | | | | | | | | | | | | | | | | | | This was useless, because immediate constraints are assumed to already be in the current environment, while deferred constraints are useless for the conversion check of the definition types, as they only appear in the opaque body. This also clarifies a bit what is going on in the typing of module constraints w.r.t. global universes.

This is very peculiar and needs more investigation as the aforementioned file does not have any sections or any universe polymorphic definitions! commit fc785326080b9451eb4700b16ccd3f7df214e0ed Author: Amin Timany <amintimany@gmail.com> Date: Mon Apr 24 17:14:21 2017 +0200 Revert STL to monomorphic commit 62b573fb13d290d8fe4c85822da62d3e5e2a6996 Author: Amin Timany <amintimany@gmail.com> Date: Mon Apr 24 17:02:42 2017 +0200 Try unifying universes before apply subtyping commit ff393742c37b9241c83498e84c2274967a1a58dc Author: Amin Timany <amintimany@gmail.com> Date: Sun Apr 23 13:49:04 2017 +0200 Compile more of STL with universe polymorphism commit 5c831b41ebd1fc32e2dd976697c8e474f48580d6 Author: Amin Timany <amintimany@gmail.com> Date: Tue Apr 18 21:26:45 2017 +0200 Made more progress on compiling the standard library commit b8550ffcce0861794116eb3b12b84e1158c2b4f8 Author: Amin Timany <amintimany@gmail.com> Date: Sun Apr 16 22:55:19 2017 +0200 Make more number theoretic modules monomorphic commit 29d126d4d4910683f7e6aada2a25209151e41b10 Author: Amin Timany <amintimany@gmail.com> Date: Fri Apr 14 16:11:48 2017 +0200 WIP more of standard library compiles Also: Matthieu fixed a bug in rewrite system which was faulty when introducing new morphisms (Add Morphism) command. commit 23bc33b843f098acaba4c63c71c68f79c4641f8c Author: Amin Timany <amintimany@gmail.com> Date: Fri Apr 14 11:39:21 2017 +0200 WIP: more of the standard library compiles We have implemented convertibility of constructors up-to mutual subtyping of their corresponding inductive types. This is similar to the behavior of template polymorphism. commit d0abc5c50d593404fb41b98d588c3843382afd4f Author: Amin Timany <amintimany@gmail.com> Date: Wed Apr 12 19:02:39 2017 +0200 WIP: trying to get the standard library compile with universe polymorphism We are trying to prune universes after section ends. Sections add a load of universes that are not appearing in the body, type or the constraints.

| |_|/ |/| | | | | | | | | | | | | | | | | | | | | | | The [let _typ = ...] comes from before universe polymorphism. In those times it was [let _typ, cst = ...] which produced something of use. The asserts come from 359e4ffe3 and before (2006 and before). In those times [Typeops.infer] rebuilt the term being typed, but nowadays the assert seems of little use.

Developed jointly by Thomas Sibut-Pinote and Hugo Herbelin. Added support for printing effect in functions of tacred.ml.

* | Creating a module Nameops.Name extending module Names.Name.Gravatar Hugo Herbelin2017-05-31
| | | | | | | | | | | | | | | | | | | | | | | | This module collects the functions of Nameops which are about Name.t and somehow standardize or improve their name, resulting in particular from discussions in working group. Note the use of a dedicated exception rather than a failwith for Nameops.Name.out. Drawback of the approach: one needs to open Nameops, or to use long prefix Nameops.Name.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is the continuation of #244, we now deprecate `CErrors.error`, the single entry point in Coq is `user_err`. The rationale is to allow for easier grepping, and to ease a future cleanup of error messages. In particular, we would like to systematically classify all error messages raised by Coq and be sure they are properly documented. We restore the two functions removed in #244 to improve compatibility, but mark them deprecated.
