Scopes

A scope is a set of interpreters for symbols + optional interpreter and printers for integers + optional delimiters

type delimiters = string
type scope
type scopes

= scope_name list

val declare_scope : Notation_term.scope_name -> unit
val ensure_scope : Notation_term.scope_name -> unit
val current_scopes : unit -> scopes
val scope_is_open_in_scopes : Notation_term.scope_name -> scopes -> bool

Check where a scope is opened or not in a scope list, or in * the current opened scopes

val scope_is_open : Notation_term.scope_name -> bool
val open_scope : Notation_term.scope_name -> unit

Open scope

val close_scope : Notation_term.scope_name -> unit
val normalize_scope : string -> Notation_term.scope_name

Return a scope taking either a scope name or delimiter

val empty_scope_stack : scopes

Extend a list of scopes

val push_scope : Notation_term.scope_name -> scopes -> scopes
val find_scope : Notation_term.scope_name -> scope
val scope_delimiters : scope -> delimiters option

Declare delimiters for printing

val declare_delimiters : Notation_term.scope_name -> delimiters -> unit
val remove_delimiters : Notation_term.scope_name -> unit
val find_delimiters_scope : ?loc:Loc.t -> delimiters -> Notation_term.scope_name
Declare and uses back and forth an interpretation of primitive token

A number interpreter is the pair of an interpreter for **(hexa)decimal** numbers in terms and an optional interpreter in pattern, if non integer or negative numbers are not supported, the interpreter must fail with an appropriate error message

type notation_location = (Names.DirPath.t * Names.DirPath.t) * string

1st dirpath: dirpath of the library 2nd dirpath: module and section-only dirpath (ie Lib.current_dirpath true) string: string used to generate the notation

dirpaths are used for dumpglob and for Locate, string for printing (pr_notation_info)

type required_module = Libnames.full_path * string list
type prim_token_infos = {
pt_local : bool;(*

Is this interpretation local?

*)
pt_scope : Notation_term.scope_name;(*

Concerned scope

*)
pt_interp_info : PrimNotations.prim_token_interp_info;(*

Unique id "pointing" to (un)interp functions, OR a number notation object describing (un)interp functions

*)
pt_required : required_module;(*

Module that should be loaded first

*)
pt_refs : Names.GlobRef.t list;(*

Entry points during uninterpretation

*)
pt_in_match : bool;(*

Is this prim token legal in match patterns ?

*)
}

Note: most of the time, the pt_refs field above will contain inductive constructors (e.g. O and S for nat). But it could also be injection functions such as IZR for reals.

Activate a prim token interpretation whose unique id and functions have already been registered.

val enable_prim_token_interpretation : prim_token_infos -> unit

val availability_of_notation : Constrexpr.specific_notation -> Notation_term.subscopes -> (Notation_term.scope_name option * delimiters option) option

Test if a notation is available in the scopes context scopes; if available, the result is not None; the first argument is itself not None if a delimiters is needed

val toggle_notations : on:bool -> all:bool -> ?verbose:bool -> (Glob_term.glob_constr -> Pp.t) -> notation_query_pattern -> unit
Miscellaneous
val interpret_notation_string : string -> string

Take a notation string and turn it into a notation key. eg. "x + y" becomes "_ + _".

type notation_as_reference_error =
| AmbiguousNotationAsReference of Constrexpr.notation_key
| NotationNotReference of Environ.env * Evd.evar_map * Constrexpr.notation_key * (Constrexpr.notation_key * Notation_term.notation_constr) list
exception NotationAsReferenceError of notation_as_reference_error
val interp_notation_as_global_reference : ?loc:Loc.t -> head:bool -> (Names.GlobRef.t -> bool) -> Constrexpr.notation_key -> delimiters option -> Names.GlobRef.t

If head is true, also allows applied global references. Raise NotationAsReferenceError if not resolvable as a global reference

Same together with the full notation

val declare_arguments_scope : bool -> Names.GlobRef.t -> Notation_term.scope_name list list -> unit

Declares and looks for scopes associated to arguments of a global ref

type add_scope_where =
| AddScopeTop
| AddScopeBottom(*

add new scope at top or bottom of existing stack (default is reset)
