2019-05-23do not parse `|` as infix in patterns; parse `|}` as `|` `}`Georges Gonthier
* use mixfix `(p1 | … | pn)` notation for nested disjunctive patterns, rather than infix `|`, making pattern syntax consistent with term syntax. * disable extending `pattern` grammar with notation incompatible with the nested disjunctive pattern syntax `(p1 | … | pn)`, such as the `(p | q)` divisibility notation used by `Numbers`. * emit a (disabled by default) `disj-pattern-notation` warning when such `Notation` is attempted. * update documentation accordingly; document incompatibilities in `changelog`. * comment special treatment of `(num)` in grammar. * update file extensions in `Pcoq` header comment. * correct the keyword declarations to reflect the contents of the grammar files; perhaps there should be an option to disable implicit keyword extension in a `.mlg` file, so that these lists could actually be checked. * parse the `|}` manifest record terminator as `|` followed by `}`, eliminating the `|}` token which conflicts with notations that use `|` as a terminator (such as, absolute value, norm, or cardinal in MathComp). Since `|` is now an `operconstr` _and_ `pattern` terminator, `bar_cbrace` rule checks for contiguous symbols, this change entails no visible behaviour change.

2019-03-31[parsing] Split Tok.t into Tok.t and Tok.patternEnrico Tassi
Tokens were having a double role: - the output of the lexer - the items of grammar entries, especially terminals Now tokens are the output of the lexer, and this paves the way for using a richer data type, eg including Loc.t Patterns, as in Plexing.pattern, only represent patterns (for tokens) and now have a bit more structure (eg the wildcard is represented as None, not as "", while a regular pattern for "x" as Some "x")
2019-03-29[parser] initialization based on Loc.t rather than Loc.sourceEnrico Tassi
In this way one can also set the current offsets in a file, useful if you are parsing a Coq fragment within a file instead of a full file starting from the first line.
2019-01-24[STM] explicit handling of parsing statesEnrico Tassi
DAG nodes hold now a system state and a parsing state. The latter is always passed to the parser. This paves the way to decoupling the effect of commands on the parsing state and the system state, and hence never force to interpret, say, Notation. Handling proof modes is now done explicitly in the STM, not by interpreting VernacStartLemma. Similarly Notation execution could be split in two phases in order to obtain a parsing state without fully executing it (that requires executing all commands before it).

The types are identical and we have no more reason for the split. Note the following TODOS: - discrepancy of `Ploc.after` with `CLexer.after` - discrepancy of `Ploc.comments` with `CLexer.comments` - `Ploc.dummy` vs `Loc.t option`

2018-11-21[gramlib] [build] Switch make-based system to packed gramlibEmilio Jesus Gallego Arias
This makes the make-based build system stop linking to Camlp5's gramlib and instead links to our own gramlib. We use the style done in the packing of `Stdlib` in OCaml 4.07. As to introduce a minimal amount of noise in history we use an autogenerated `gramlib__pack` directory. Co-authored-by: Gaëtan Gilbert <gaetan.gilbert@skyskimmer.net>

2018-07-29Adding support for custom entries in notations.Hugo Herbelin
- New command "Declare Custom Entry bar". - Entries can have levels. - Printing is done using a notion of coercion between grammar entries. This typically corresponds to rules of the form 'Notation "[ x ]" := x (x custom myconstr).' but also 'Notation "{ x }" := x (in custom myconstr, x constr).'. - Rules declaring idents such as 'Notation "x" := x (in custom myconstr, x ident).' are natively recognized. - Rules declaring globals such as 'Notation "x" := x (in custom myconstr, x global).' are natively recognized. Incidentally merging ETConstr and ETConstrAsBinder. Noticed in passing that parsing binder as custom was not done as in constr. Probably some fine-tuning still to do (priority of notations, interactions between scopes and entries, ...). To be tested live further.

2018-07-07Introduce a Pcoq.Entry module for functions that ought to be exported.Pierre-Marie Pédrot
We deprecate the corresponding functions in Pcoq.Gram. The motivation is that the Gram module is used as an argument to Camlp5 functors, so that it is not stable by extension. Enforcing that its type is literally the one Camlp5 expects ensures robustness to extension statically. Some really internal functions have been bluntly removed. It is unlikely that they are used by external plugins.
2018-07-07Remove dead code that used to be there for CamlpX compatibility.Pierre-Marie Pédrot
Part of this code has been introduced very recently in 7c62654 in spite of the existence of a proper API. This means that this should be better documented.
2018-07-06Fix compilation of Coq with camlp5 master branch.Pierre-Marie Pédrot
There was a conflict in the name of an exported function. A good argument in favour of PR #7898.
2018-06-29Use a homebrew parser to replace the GEXTEND extension points of Camlp5.Pierre-Marie Pédrot
The parser is stupid and the syntax is almost the same as the previous one. The only difference is that one needs to wrap OCaml code between { braces } so that quoting works out of the box. Files requiring such a syntax are handled specifically by the type system and need to have a .mlg extension instead of a .ml4 one.

2018-05-27[api] Make `vernac/` self-contained.Emilio Jesus Gallego Arias
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.

2018-02-28[toplevel] Move beautify to its own pass.Emilio Jesus Gallego Arias
We first load the file, then we print it as a post-processing step. This is both more flexible and clearer. We also refactor the comments handling to minimize the logic that is living in the Lexer. Indeed, the main API is now living in the printer, and complex interactions with the state are not possible anymore, including the removal of messing with low-level summary and state setting!

2017-12-20Separate vernac controls and regular commands.Maxime Dénès
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.
2017-12-09[summary] Allow typed projections from global state + rework of internals.Emilio Jesus Gallego Arias
In the transition towards a less global state handling we have the necessity of mix imperative setting [notably for the modules/section code] and functional handling of state [notably in the STM]. In that scenario, it is very convenient to have typed access to the Coq's `summary`. Thus, I reify the API to support typed access to the `summary`, and implement such access in a couple of convenient places. We also update some internal datatypes to simplify the `frozen` data type. We also remove the use of hashes as it doesn't really make things faster, and most operations are now over `Maps` anyways. I believe this goes in line with recent work by @ppedrot. We also deprecate the non-typed accessors, which were only supposed to be used in the STM, which is now ported to the finer primitives.

2017-09-19Allow declaring universe constraints at definition level.Matthieu Sozeau
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.

Today, both modes are controlled by a single flag, however this is a bit misleading as is_silent really means "quiet", that is to say `coqc -q` whereas "verbose" is Coq normal operation. We also restore proper behavior of goal printing in coqtop on quiet mode, thanks to @Matafou for the report.
