* Update headers following #6543.Gravatar Théo Zimmermann2018-02-27

* [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.
* Adding support for parsing subterms of a notation as "pattern".Gravatar Hugo Herbelin2018-02-20
| | | | | | | | | | | | | | | | | | | | This allows in particular to define notations with 'pat style binders. E.g.: A non-trivial change in this commit is storing binders and patterns separately from terms. This is not strictly necessary but has some advantages. However, it is relatively common to have binders also used as terms, or binders parsed as terms. Thus, it is already relatively common to embed binders into terms (see e.g. notation for ETA in output test Notations3.v) or to coerce terms to idents (see e.g. the notation for {x|P} where x is parsed as a constr). So, it is as simple to always store idents (and eventually patterns) as terms.
* Moving the argument of CProdN/CLambdaN from binder_expr to local_binder_expr.Gravatar Hugo Herbelin2018-02-20
| | | | | | | | | | | | | | | | | | | | The motivations are: - To reflect the concrete syntax more closely. - To factorize the different places where "contexts" are internalized: before this patch, there is a different treatment of `Definition f '(x,y) := x+y` and `Definition f := fun '(x,y) => x+y`, and a hack to interpret `Definition f `pat := c : t`. With the patch, the fix to avoid seeing a variable named `pat` works for both `fun 'x => ...` and `Definition f 'x := ...`. The drawbacks are: - Counterpart to reflecting the concrete syntax more closerly, there are more redundancies in the syntax. For instance, the case `CLetIn (na,b,t,c)` can appears also in the form `CProdN (CLocalDef (na,b,t)::rest,d)` and `CLambdaN (CLocalDef (na,b,t)::rest,d)`. - Changes in the API, hence adaptation of plugins referring to `constr_expr` needed.
* Use r.(p) syntax to print primitive projections.Gravatar Maxime Dénès2018-01-30
| | | | | | | | | | | | | There is no way today to distinguish primitive projections from compatibility constants, at least in the case of a record without parameters. We remedy to this by always using the r.(p) syntax when printing primitive projections, even with Set Printing All. The input syntax r.(p) is still elaborated to GApp, so that we can preserve the compatibility layer. Hopefully we can make up a plan to get rid of that layer, but it will require fixing a few problems.
* Removing cumbersome location in multiple patterns.Gravatar Hugo Herbelin2017-12-12
| | | | This is to have a better symmetry between CCases and GCases.
* [api] Move structures deprecated in the API to the core.Gravatar Emilio Jesus Gallego Arias2017-11-06
| | | | We do up to `Term` which is the main bulk of the changes.
* 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.

* Constrexpr.Numeral stays uninterpreted (string+sign instead of BigInt.t)Gravatar Pierre Letouzey2017-06-14
| | | | | | This string contains the base-10 representation of the number (big endian) Note that some inner parsing stuff still uses bigints, see egramcoq.ml
* Put all plugins behind an "API".Gravatar Matej Kosik2017-06-07
