From fa9df2efe5666789bf91bb7761567cd53e6c451f Mon Sep 17 00:00:00 2001 From: Emilio Jesus Gallego Arias Date: Sun, 18 Dec 2016 18:14:58 +0100 Subject: [stm] Break stm/toplevel dependency loop. Currently, the STM, vernac interpretation, and the toplevel are intertwined in a mutual dependency that needs to be resolved using imperative callbacks. This is problematic for a few reasons, in particular it makes the interpretation of commands that affect the document quite intricate. As a first step, we split the `toplevel/` directory into two: "pure" vernac interpretation is moved to the `vernac/` directory, on which the STM relies. Test suite passes, and only one command seems to be disabled with this approach, "Show Script" which is to my understanding obsolete. Subsequent commits will fix this and refine some of the invariants that are not needed anymore. --- vernac/metasyntax.mli | 63 +++++++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 63 insertions(+) create mode 100644 vernac/metasyntax.mli (limited to 'vernac/metasyntax.mli') diff --git a/vernac/metasyntax.mli b/vernac/metasyntax.mli new file mode 100644 index 000000000..57c120402 --- /dev/null +++ b/vernac/metasyntax.mli @@ -0,0 +1,63 @@ +(************************************************************************) +(* v * The Coq Proof Assistant / The Coq Development Team *) +(* unit + +(** Adding a (constr) notation in the environment*) + +val add_infix : locality_flag -> (lstring * syntax_modifier list) -> + constr_expr -> scope_name option -> unit + +val add_notation : locality_flag -> constr_expr -> + (lstring * syntax_modifier list) -> scope_name option -> unit + +val add_notation_extra_printing_rule : string -> string -> string -> unit + +(** Declaring delimiter keys and default scopes *) + +val add_delimiters : scope_name -> string -> unit +val remove_delimiters : scope_name -> unit +val add_class_scope : scope_name -> scope_class list -> unit + +(** Add only the interpretation of a notation that already has pa/pp rules *) + +val add_notation_interpretation : + (lstring * constr_expr * scope_name option) -> unit + +(** Add a notation interpretation for supporting the "where" clause *) + +val set_notation_for_interpretation : Constrintern.internalization_env -> + (lstring * constr_expr * scope_name option) -> unit + +(** Add only the parsing/printing rule of a notation *) + +val add_syntax_extension : + locality_flag -> (lstring * syntax_modifier list) -> unit + +(** Add a syntactic definition (as in "Notation f := ...") *) + +val add_syntactic_definition : Id.t -> Id.t list * constr_expr -> + bool -> Flags.compat_version option -> unit + +(** Print the Camlp4 state of a grammar *) + +val pr_grammar : string -> Pp.std_ppcmds + +type any_entry = AnyEntry : 'a Pcoq.Gram.entry -> any_entry + +val register_grammar : string -> any_entry list -> unit + +val check_infix_modifiers : syntax_modifier list -> unit + +val with_syntax_protection : ('a -> 'b) -> 'a -> 'b -- cgit v1.2.3
