* Remove reference name type.Gravatar Maxime Dénès2018-06-18
| | | | | | | | reference was defined as Ident or Qualid, but the qualid type already permits empty paths. So we had effectively two representations for unqualified names, that were not seen as equal by eq_reference. We remove the reference type and replace its uses by qualid.

* [notations] Split interpretation and parsing of notationsGravatar Emilio Jesus Gallego Arias2018-05-31
| | | | | | | | Previously to this patch, `Notation_term` contained information about both parsing and notation interpretation. We split notation grammar to a file `parsing/notation_gram` as to make `interp/` not to depend on some parsing structures such as entries.
* [api] Make `vernac/` self-contained.Gravatar Emilio Jesus Gallego Arias2018-05-27
| | | | | | | | | | | | | | | | | | | | We make the vernacular implementation self-contained in the `vernac/` directory. To this extent we relocate the parser, printer, and AST to the `vernac/` directory, and move a couple of hint-related types to `Hints`, where they do indeed belong. IMO this makes the code easier to understand, and provides a better modularity of the codebase as now all things under `tactics` have 0 knowledge about vernaculars. The vernacular extension machinery has also been moved to `vernac/`, this will help when #6171 [proof state cleanup] is completed along with a stronger typing for vernacular interpretation that can distinguish different types of effects vernacular commands can perform. This PR introduces some very minor source-level incompatibilities due to a different module layering [thus deprecating is not possible]. Impact should be relatively minor.

* [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.

* [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.
* Change default for notations with variables bound to both terms and binders.Gravatar Hugo Herbelin2018-02-20
| | | | For compatibility, the default is to parse as ident and not as pattern.
* Notations: Adding modifiers to tell which kind of binder a constr can parse.Gravatar Hugo Herbelin2018-02-20
| | | | | | | | | | | | Concretely, we provide "constr as ident", "constr as strict pattern" and "constr as pattern". This tells to parse a binder as a constr, restricting to only ident or to only a strict pattern, or to a pattern which can also be an ident. The "strict pattern" modifier allows to restrict the use of patterns in printing rules. This allows e.g. to select the appropriate rule for printing between {x|P} and {'pat|P}.

* Respecting the ident/pattern distinction in notation modifiers.Gravatar Hugo Herbelin2018-02-20

* 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.

* Introducing an intermediary type "constr_prod_entry_key" for grammar ↵Gravatar Hugo Herbelin2018-02-20
| | | | | | | | | | | | | | | productions. This type describes the grammar non-terminal. It typically contains ETConstrList (now renamed ETProdConstrList) but not ETBinder. It is the type for metasyntax.ml and egramcoq.ml to communicate together. The type constr_prod_entry_key with ETConstr, ETBinder, is now used only in metasyntax.ml. This allows to get rid of some "assert false" in uselessly matching over ETConstrList in metasyntax.ml and of some "assert false" in uselessly matching over ETBinder in egramcoq.ml. Also exporting less of extend.mli in API.

* Separate vernac controls and regular commands.Gravatar Maxime Dénès2017-12-20
| | | | | | | | | | | | Virtually all classifications of vernacular commands (the STM classifier, "filtered commands", "navigation commands", etc.) were broken in presence of control vernaculars like Time, Timeout, Fail. Funny examples of bugs include Time Abort All in coqtop or Time Set Ltac Debug in CoqIDE. This change introduces a type separation between vernacular controls and vernacular commands, together with an "under_control" combinator.

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.

| |/ |/| | | | | | | | | | | | | | | | | | | An incoming commit is removing some toplevel-specific global flags in favor of local toplevel state; this commit flags `Flags` use so it becomes clearer in the code whether we are relying on some "global" settable status in code. A good candidate for further cleanup is the pattern: `Flags.if_verbose Feedback.msg_info`

* A little reorganization of notations + a fix to #5608.Gravatar Hugo Herbelin2017-08-29
| | | | | | | | | | | | | | - Formerly, notations such as "{ A } + { B }" were typically split into "{ _ }" and "_ + _". We keep the split only for parsing, which is where it is really needed, but not anymore for interpretation, nor printing. - As a consequence, one notation string can give rise to several grammar entries, but still only one printing entry. - As another consequence, "{ A } + { B }" and "A + { B }" must be reserved to be used, which is after all the natural expectation, even if the sublevels are constrained. - We also now keep the information "is ident", "is binder" in the "key" characterizing the level of a notation.

We support this by translating "x , .. , y , z" into "x , y , .. , z" and reassembling the arguments appropriately after parsing.

* [cleanup] Unify all calls to the error function.Gravatar Emilio Jesus Gallego Arias2017-05-27
| | | | | | | | | | | | | 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.

We don't print <unknown> anymore in the case there is no location. This is what the test suite expects. The old printing logic for located items was a bit inconsistent as it sometimes printed <unknown> and other times it printed nothing as the caller checked for `is_ghost` upstream.
